18 Claims.

My invention concern a golf ball teeing machine, and in particular, one which will operate automatically to place a ball in teed position for driving each time a ball is struck from such position.

In order to improve the golfers form, particularly in driving, establishments known as driving ranges have been set up where golfers may drive repeatedly from a single location without playing the driven balls farther or retrieving them. Successive balls to be driven may be teed manually in the usual way, but for such establishments machines have been proposed to toe the balls, so that it will not be necessary for the golfer to expend the time and effort necessary for this purpose.

Most of the machines developed heretofore have required manual operation by the golfer, such as by means of a, foot lever, the operation of which, just as in manually placing the ball, has required the golfer to change his stance; so that he must reposition himself each time between successive strokes. Fully automatic Inachines have been proposed heretofore, but they have been unsatisfactory because their operation has been unreliable, and they have been of complicated construction and expensive to manufacture.

In general my mechanism includes a vertically reciprocable teeing member to which balls are fed successively, while in its lowered position, from a storage bin and gravity chute. Differentially reciprocable gates control movement of the balls through such chute for delivery one by one and in timed relationship with movement of the teeing member. Reciprocation of the tee and parallel gate members is effected by individual eccentric wheels disposed in vertical planes and. all secured to and driven by the same shaft; This operating shaft is rotated slowly by any suitable drive arrangement, such as an electric motor provided with gear reduction mechanism.

A very important feature of my machine is the system for controlling operation of the drive shaft. Such control system is electrically operated by the use of amechanically actuated circuit. breaking switch and a photoelectric cell. This cell is disposed at one side of the position occupied by a ball to be driven, while a cell energizing light source, continuously illuminated, is placed at the other side of such teed ball position. The photoelectric cell may be located above the tee member, for example, while the. light source may be below it. Such tee-is longitudinally apertured for transmission of a light beam through it to the photoelectric cell when a ball is not in teed position. As long as a ball occupies this driving position, the ball teeing control is quiescent, but when the ball isstruck or otherwise removed from the tee, the photoelectric cell is energized by the light source to close an electric circuit, for initiating operation of the machine to place another ball in teed position. When the ball has been located thus, the photoelectric cell is no longer energized, but the machine continues to operate until a mechanical circuit breaking switch is opened by the ball delivering mechanism, again to deenergize the machine drive with a ball in teed, driving position.

A principal purpose of my invention, therefore, is to provide an automatic golf ball teeing machine which is of simple construction, yet which is positive and'reliabl in operation. More specifically, such object is accomplished by the use of a photoelectric cell and light source combination located on opposite sides of the teed position of a golf ball, so that when a ball is not in such position the photoelectric cell will be energized by a light beam from the light source passing through such position.

A further object is to make such an automatic unit of compact construction, and one which may be connected in multiple with like units alloperated by a single drive. In such installations, of course, proper safety devices should be provided to guard against breaking the drive mechanism or the other units.

A unit embodying the principles of my invention is illustrated in the drawings. It will be evident that changes in details and construction may be made to adapt such unit to particular installations, or for structural or design reasons, without altering the general mode of operation of the machine.

Figure 1 is a plan view of my machine, and Figure 2 is a side elevation view thereof with parts broken away to show internal structure.

Figure 3 is a vertical section taken on line 3-3 of Figure 2, and Figure 4 is another vertical section taken on line 4-4 of Figure 1.

Figure 5 is a fragmentary section taken on line 5-5 of Figure 1, showing part of the control mechanism. I

Figure 6 is a diagrammatic perspective view illustrating the mechanical operation of the machine, and showing the wiring diagram of the electrical control system.

Each teeing unit is complete in itself, except for its. motive power which preferably is supplied by an external source. Golf balls are delivered to ed upon a base plate 3.

the teeing member from an inclined gravity feed tube or chute I, which in turn receives the balls from a storage container I0. These balls roll down the chute into an upright tube 2 within which the ball raising and teeing plunger 20 reciprocates. Preferably the tube or chute I is secured integrally to tube 2, from which it branches, to be supported by the latter. The upright tube in turn may be held in a flanged socket 2| mount- The upper end of this tube projects through a hole in floor F, and the ball storage container I may also be supported from the floor and project above it.

Only one ball at a time may be fed from the gravity chute I to the upright tube 2, and the timing of such delivery is controlled by differentially reciprocable gate bars II and I2, which are guided for lengthwise slots I3 projecting downwardly from sleeve I4, which latter may encircle and reinforce tube I adjacent to its connection with tube 2. Reciprocation of the gate bars II and I2 is effected by eccentric collars I5 and I6, respectively, pivoted to such bars, and encircling eccentric wheels 40 and 4|, respectively, carried by shaft 4. Differential movement of the bars is produced by setting the eccentric wheels 4!] and 4I in opposite phase upon the shaft, that is, spaced apart 180 degrees, so that as bar II is moved upward, bar I2 will be moved downward, and vice versa.

It is only necessary that the gate bars II and. I2 project upward into tube I a distance sufficient to prevent passage of the balls past these gates. The greater the diameter of eccentric wheels 40 and 4I, of course, the more quickly will they move between ball-holding and ball releasing positions. In Figure 2 gate II is shown in block- .ingposition, while in Figure 6, in full lines, it is shown in retracted position, which latter p0sition "is reached in the middle of a cycle. Gate I2, on'the other hand, is shown retracted in Figure 2, while in Figure 6, in solid lines, it has been raised to blocking position.

When a ball is released, in the manner shown in Figure 6, the lifting plunger must be in its lowered position. ,It is raised to the broken line position, shown in solid lines in Figure 2, by rotation of eccentric wheel 42, which engages roller 22 fastened to the plunger. Preferably, this roller is journalled on a spindle 23 integral with, and disposed centrally of, a plate 24, curved laterally to conform to the exterior of tube 2. Screws 25 extend through holes at top and bottom of this, plate for guiding engagement in a longitudinal slot 26 in the wall of tube 2, and are screwed into tapped holes in the body of plunger 29. Such interengagement of the slotted tube wall between plate 24 and block 20 prevents tilting of the plunger as it passes the junction of chute 2 with tube I, and also restrains rotation of the plunger as eccentric wheel 42 exerts a side thrust on roller 22.

In order to coordinate the movements of gate bars II and I2 with plunger 20, eccentric wheel 42 is secured on shaft 4 in substantially the same angular relationship as eccentric wheel 46. This insures that the plunger will be in its lower position when gate bar II is retracted sufficiently to enable the next ball B to be delivered from gravity chute I into upright tube 2, as shown in Figure 6. Moreover, the plunger will have descended far enough at such time so that the ball will roll onto the tee tube 24, extending axially through and projecting well above it. Preferably this tube is made of flexible material, such as rubber, so that movement in spaced guide when the ball is driven from it, or if the tube itself is struck by a golf club, it will bend, instead of it being broken, or the golf club being shattered, or some other part of the machin being damaged.

The structure for reciprocating plunger 2e and gates II and I2 may vary in construction and may be mounted in different ways. In order that each unit be compact, and as far as possible self-contained, however, I prefer that the driving mechanism be supported on standards 38 mounted on plate 3. Four of these standards may be provided, upon three of which a raised mounting plate 3! is supported. Two standards in alignment function as, or carry, end bearings 32 for a driven shaft 4 on which the eccentric wheels 40, 4| and 42 are secured. A driving shaft 53 is supported at one end by a third bearing 32 on a standard 30 aligned with the above-mentioned bearing standards. This latter shaft is continuously rotated at a slow speed by a pulley 34, driven by a belt 38 from a pulley secured upon a line shaft 31. This line shaft will extend ad J'acent'to all the several teeing units of a driying range installation, and will also be rotated continuously. The belt 36 interconnecting the driving and driven pulleys 35 and 3 respectively, will serve as a safety connection between each teeing unit and the master drive shaft, so that if, for any reason, the unit driven by it should jam, this belt would be thrown off the pulleys, enabling the other teeing units to b operated uninterruptedly without risk of injury.

It will be evident that driven shaft 4 must be mechanically separate from the continuously rotating drive shaft 33 in order to accomplish intermittent operation of the teeing mechanism. These shafts, however, may be in alignment, as shown, and in fact the end of shaft 33 adjacent to shaft 4 may be supported from it by a bearing 43, serving to restrict both radial and thrust movement of the shaft end, so that although shaft 33 may rotate continuously, it will not drive shaft 4 directly and synchronously, because of the interposition of this hearing.

In order to rotate shaft 4 intermittently by shaft 33, positive clutch mechanism, which may be of the claw clutch type, is provided. Such a clutch may incorporate a driving element 64 rotating continuously with shaft 33, adapted to mesh with a driven clutch element secured to shaft 4. Normally these elements would be held out of engagement by a clutch releasing spring it, interengaged between the clutch element 44 and a shoulder or an abutment on the end of shaft 33 engaged with bearing 43. To engage elements 4 and 45 for rotating shaft 4, a shifter 41 may be operated to slide element 44 along shaft 33 into contact with element 45. To enable element 34 to move thus it is slidably splined or keyed to shaft 33, such as by a feather or key 33, which constitutes the driving connection between the shaft and driving clutch element. By such movement between clutch element 44 and shaft 35 clutch spring 45 is compressed, so that immediately upon release of shifter 4f the clutch ele ments will be separated automatically b exp-an sion of this spring. Disengagement of the cit 11 elements can also be effected, even if the clutch spring 46 is not provided, by opposite movement of shifter 41.

As shown best in Figures 1 and 4, the driving clutch element 44 may be a disk having radial serrations about the margin of one face, with which complemental serrations on driven clutch a few circumferentiallyspaced. groupsof serra- Y tions are provided on one element, such asithe driven member 44.

In order to afford automatic control of the teeingmechanism, I prefer that the clutchbe electrically operated by a solenoid fi, which, when energized, will draw a plunger fail 'inward. This movement actuates a lever system d8, preferably of the compound type, as shown in Figural, to move clutch shifter ll. It will be evident, therefore, that whenever the solenoid is energized, plunger 50 will be moved to engage clutch elements 44 and 45 for driving shaft l, which in turn rotates eccentric wheels 48, M and t2, and upon deenergization of solenoid 5 spring 45; ex-

panding to disengage the clutch elements, will swing the levers 58 for again withdrawing plunger 5|! from solenoid 5. In addition, in order to stop shaft 4 and the eccentric wheels carried by it at the instant that clutch elements as and 15 are disengaged, I provide a brake head d9, carried by one lever of the lever system M3, which will be forced into engagement with eccentric wheel 42 by the expansion of clutch release spring it. Other suitable brake mechanism might be substituted for head 69, which .might act to stop any member connected to move with shaft 4.

Each time a ball is driven from the tee tube 2'1, it is only necessary that the mechanism move through a complete cycle executed by a single revolution of shaft 4 to deliver another ball to tube 2 and to raise it into teed position. Especially since it is desirable to drive eachunit from thesame power source, such as an electric motor, however, movement of themechanism of each in..- dividual unit should be controlled separately. In order to relieve the player from giving: any attention to the machine, however, such control should be automatic and absolutely dependable. I therefore have devised a control system which is electrically operated, and depends upon mechanical action as little as possible.

The heart of my electrical control arrangement is a photoelectric cellfii, which is energized to initiate a ball teeing cycle by light, such as from a lamp 52 which is illuminated continuously during use of the unit. Such photoelectric cell and lamp are positioned so that the photoelectric cell energizing light beam will pass through" the teed. position of the ball. When a ball is not in such teedposition to intercept the light beam, therefore, the photoelectric cell willbe energized to tee another ball. To this end the photoelectric cell 5| and lamp 512 may be placed in anyof various positions, on opposite sides of the upperend of tee tube 2?, but I prefer that one element, such as the photoelectric cell, be placed above theteed position of the ball, and the other element, such as lamp 52, below the tee, as shown in Figure 2. Light from the lamp will shine upward through the hollow tube 2'l, extending completely through plunger 26) and serving as the ball tee.

While the photoelectric cell has been shown above the ball, and the lamp 52, constituting the energizing light source, below the tee and within H tube 2, the positions of these elements might be reversed; With the photoelectric cell thusfligposedin the base of tube, 2, daylight, r 'thegeneral night: illumination of. the driving course, shininggdown through .tube. 21,, could replacethe by closing of switch special lamp 532 as the light source to energize the photoelectric. cell whenever such tube is not covered by agolf ball, provided that the. photoelectric cell is sufficiently sensitive. In whateverpositionphotoelectriccell 5! is located, its energizetion by a light beam from a light source on the opposite side of the teed position of the ball will operate. arelay 53 to close a normally opencontrol switch 53, which is in series circuit with clutch operating solenoid 5.

Assuming, therefore, that a golf ball B i in teed position on tube 21, photoelectric cell 5i will remain deenergized, and switch 54 will stay open, sothat current cannot now through solenoid 5 for effecting engagement of clutch members 44 and 45. When the ball is driven from the tee tube the photoelectric cell will be energized by the light beam passing through the teed position of the ball. Relay 53 will be actuated by the photoelectric cell to close switch 54, and current will flow through solenoid ii to draw its plunger 58 to the right in Figure 1, thus moving levers 48 and shifter if to engage clutch elements 44 and 45. Because shaft 33 rotates continuously, shaft 4 will be rotated with it by such clutch engagement, in turn to revolve eccentric wheels M), M and 52.

During the first portion of the rotation of eccentric wheel til a ball B will be released from chute l by retraction of gate bar H, to roll by gravity into upright tube 2. Meanwhile, rotation of cam wheel s2 to the position shown in full linesin Figure 6, has allowed plunger 28 to descend so that the top of tee tube 2'! is slightly below the junction of the bottom of tube I wit tube 2. Thus the ball will fall onto the tee tube, immediately intercepting the beam of light, until that time energizing photoelectric cell 5!, so that relay 53 will be deenergized and switch 54 will open. The electric circuit through clutch operating solenoid 5 will not thus be broken, however, because its circuit will still be completed through a normally closed switch 55, which is connected in parallel with switch #3.

tee, so that switch 54 remains open, the circuit through solenoid 5 will thus be disrupted with plunger 28 in its raised position, shown in FiguresZ and 3. Clutch spring it: will immediately separate clutch members 14 and it and withdraw plunger 5i! from solenoid 5, while brake flawill engage eccentric wheel filfi to stop and hold the mechanism positively in this position. Shortly after the next cycle is initiated 5% upon energization of sole noid 5i, cam hump 55 will pass beyond'switch 55 so thatit will again close before another ball enters tube 2 to intercept the photoelectric cell energizing beam.

While gate H is in its depressed position, as shown in solid lines in Figure 6, the balls in tube I, with the exception of the one between gates.

H and I2, are held back by upward projection into it of gate bar l2. Upon continued rotation of shaft 5, however, gate :2 is withdrawn as gate H is again raised, and all the ballsintthez-tube roll. down until. the new foremost one lodges against. gate. ll. Since only one: ball can. be

accommodated between gates I I and I2, on initiation of the next operating cycle this ball alone will be delivered into tube 2 in the manner described.

If storage bin IQ and tube I should be empty, no ball would be delivered to tee tube 21 during the above operation. There would be nothing to interrupt the beam of light through the teed position of the ball, and it would therefore continue to energize photoelectric cell 5!. Consequently relay 53 would remain energized to hold switch 54 closed, and despite the intermittent opening and closing of switch 55 by cam hump 56 as eccentric wheel 42 rotates, current would flow continuously to solenoid ti through switch 56 to hold clutch elements 44 and t5 engaged and thus to rotate shaft 4 indefinitely. Plunger 2|? and gates l i and I2 will continue 'to reciprocate up and down in timed relationship, therefore, until an additional supply of balls hasbeen fed into tube I.

Even though no balls are available each individual unit can be rendered inoperative bylmechanically preventing access of light to phtoelectric cell or by deenergizing the source of illumination, as by opening switch 51 which controls lamp 52. The photoelectric cell would not be energized to actuate relay 53, so that switch 54 would stay open and shaft 4 would remain stationary with plunger 29 in raised position, in which position switch 55 is held open by cam hump 56. Despite any single unit being thus rendered inoperative, the rest of the units can be operated continuously, if desired, by rotation of motor 58 driving line shaft 31,

It will be seen, therefore, that each unit will continue to operate as long as balls are supplied to it, irrespective of the other units, although all are driven by a single motor, unless voluntarily rendered inoperative. Only When a ball has been teed will each operating unit stop at the end of its operating cycle. As soon as the ball has been driven from teed position another cycle will commence Without fail, and this no matter what defect of shape, size or Weight the golf ball may possess.
