MOTOR.

SPECIFICATION forming part of Lette-rs Patent No. 737,115,.da,ted August 25,1903. Application filed March 3,1903- Serial No. 146,028. (No model.)

To all whom it mafyrconcern: Y Be it known that I, CHARLES M. KILER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State,

of Indiana, have invented certain new and useful Improvements in Motors, of which the following is a specification. f

This invention relates to improvements in motors operated by weight or spring, and preferably by weight, for pumping, grinding, andv doing all kinds of lightwork on a farm or in 'a shop; and the object of the invention is to` .ture and easy to operate by an inexperienced person.V

I accomplish the objects of the invention by the mechanism illustrated in the accomvpanying drawings, in which- Figure 1 is a perspective view of my invention connected up for pumping purposes; Fig. 2, a vertical section of the Weights used in the device shown in Fig. 1; Fig. 3, a detail in side elevation and partial section of the mechanism for shifting the governor-fans; Fig.` 4, a typical detail in perspective of the lever and sliding pinions used at several parts of my invention to disconnect certain of the parts;` Fig.' 5, a side elevation of the pawl mechanism for holding the drum on which the weighted cable is wound; and Fig. 6, a detail in transverse section of the auxiliary or crank drum, showing the details of `mechanism by which the crank-pawl is disengaged from the druml ratchet.

' as shown in dotted lines in Fig. 5.

the top of the tower o is made fast` 'to the weights 6. By winding the cable upon the drum the weights are hoisted in the air, and the lowering of the weights by gravity furnishes the power for the motor, the purpose of the latter being to husband the power andl make it available for practical purposes.

7 is a shaft from which the power is taken and which I shall hereinafter refer toas the v power-shaft. On it is mounted the wheel 8, which may serve as a belt-wheel--when it is desired to transmit rotary motion, or it may be a crank-wheel, asin the drawings, when it isA desired to transmit reciprocatory movement. The shaft on which drum 2 is mounted is connected with the shaft 7 by a train of cogwheels 9, 10, 1l, 12, 13, and 14, which increase speed at the expense of power. The wheel 10 (see Figs. 1 and 4) is splined to its shaft and is shifted longitudinally of the shaft into pawl-lever 17 during the winding process to keep the weight from running down by any accidental release ot' the drum. This pawllever 17 is drawn into contact with the ratchets by spring 18 and is thrown out of engagement by the outward throw of bent lever 19,

The opposite en d of power-shaft 7 from wheel 8 proi jects beyond the frame l, and on this projecting end'are the four governor-fansr20, which bythe "resistance of the air through which they are forced to travel regulate the speed of said power-shaft. The resistance will be greatest when the fans are turned broadside to the direction of their travel and least when turned edgewise. to said .travel. Between these extremes are many variations of resistance, and I' provide the following-described means for adjusting the fans:

The fans have stems 2l, which are round in cross-section next to the fan and squared at their inner portions.

22 is the spider to the arms of which the fan-stems are secured. These arms have inside lugs 23 with radial bores to receive the stems 21.

24 represents levers or cranks having lateral shanks 25 with longitudinal holes squared in cross-section to receive the squared ends of stems 2l. Said stems have longitudinal adjustment iu said shanks Within certain limits while being compelled to rotate with the shanks. The given adjustment of the stems is held by set-screws 26.

27 is a hub splined to shaft 7, so as to rotate with said shaft, but adjustable longitudinally thereon. It has the lugs 28, which are connected by links 29 with the levers 24, as shown in Fig. 3, so that by the longitudinal movement on shaft 7 of said hub the levers 24 will be moved to rotate the fans. The hub 27 has a circumferential groove to receive the collar 29, having trunnions which pivotally engage the opposite forks of the bifurcated lever 30. The opposite end of lever 30 is pivotally secured to lever 3l. The latter is pivoted to the frame of the motor and has a dog 32 to engage the rack 33 and hold any given adjustment of the fans. By means of the lever 31 the fans may be adjusted without stopping the motor. This is particularly desirable with motors operating a pump where the pump has to be primed on starting and requires to be operated at a higher speed at that time than lateron while pumping Water. By adjusting the fans longitudinally, as above provided, the leverage exerted by them is increased or diminished, thereby affording an additional regulation.

I will now describe the Winding mechanism employed by me.

34 is a shaft supported by the motor-frame and having the small pinion 35, which is splined to its shaft-like pinion 10, and said pinion 35 is thrown in or out of engagement with wheel 9 by being moved longitudinally of shaft 34 by the lever 36. The construction and adaptation of lever 36 is the same as lever 15. (Shown in Fig. 4.) It has a shifting plate like 16, engaging a groove in the hub of pinion 35 in same manner as the pinion shown at 10 in said Fig. 4. This shaft also has the larger cog-wheel 37, which engages the pinion 38 of adjacent parallel shaft 39.

Mounted either on shaft 34 or shaft 39, and here shown as on shaft 39, is the drum 40, to which the cable 41 is fastened and several turns of said cable wound upon the drum. By hitching a horse to the other end of the cable and drawing it out in the direction shown in Fig. 1 the drum will be rotated in a direction to operate the mechanism which will wind the cable 3 on the drum 2. The two rims ofv the drum will be provided with ratchet-teeth, which are in reverse order for the two rims, and these will be engaged by the oppositely-acting pawls 42 and 43, which will be brought into ilse one at a time, de-

remis pending on the direction which it is desired to move the drum. The pawl not desired to be operative at a given time will be thrown 4 back out of engagement with its ratchetwheel.

Mounted on the shaft 39 is lever 44, having pawl 45 to engage the teeth of the adjacent rim of the drum in the manner shown in Fig. 1, and the upper end of the lever is connected by the cable 46 with a third drum 47, supported at the side of the motor-frame 1. The drum 47is loosely mounted on the shaft 48, and the shaft 48 is rotated by means of the crank 49. The crank-lever has the paWl 50, which contacts with the si-ngle tooth 51 on the adjacent rim of the drum 47, so as to lock the crank and drum together and cause the cable 46 to be wound upon the drum 47 when the crank is turned in the properdirection and draw the lever over toward drum 47, thereby through the connecting-train of gears causing the drum 2 to be driven in direction to wind cable 3 on it. When the end of lever 44 has reached the limit of its movement, the pawl 45 is raised by the incline 52, acting on pin 52 from pawl'45, out of engagement with the tooth 51, thereby releasing the loosely-mounted drum. Thereupon the lever 44 is returned toits first position by the weight 53 or by means of a spring (not shown) substituted for the weight and connecting the end of the lever with the motorframe. In operating with the lever 44 the pawl 42 will be first thrown out of engagement With the drum. By the use of lever 44 I get the advantage of the long leverage in raising the weight 6 and by means of the associated mechanism am enabled to operate the lever by a continuous turning of the crank 49.

The weights 6 are here shown as a plurality of separate plates or disks having a radial slot 54 to allow them to be slipped laterally upon the cable and having holes and dowelpins 55 of one entering the holes of the disk nnderit to prevent displacement. ln assembling the disks the radial slots will be turned ninety degrees from the direction of the one adjacent to it to better hold the positions of the disks on the cable. The disks will be of cast-iron; but other forms of weights and other material may be used without departing from the spirit of this invention.

Mounted at the rear of motor-frame lis the horizontal shaft 56, on which is loosely mounted the arm 57, which is connected by link 58 withtherodofpump). Alsomountedloosely on shaft 56 is the approximately vertical lever 60, which is held a predetermined angular distance from arm 57 by the bar 61. The bar 6l has a series of perforations to receive bolt 62, which connects it with the lever 60. The lever 60 is connected by pitman 63 with the Wrist-pin 64 on the side of wheel 8. The lever 60 extends a considerable distance above its connection with pitman 63 and is provided with the weight 65, which by its gravity assists the motor in operating the pump, for

when the purnp is lifting water lever 60 and its Weight are on the downstroke of'the oscillatory movement of said lever around shaft 56. The return stroke when the piston of the pump is descending requires much less power Afrom the motor, andthe excess is utilized in raising the weight 65. The lever 60 and the pitman have a series of perforations for the connecting-bolt to allow of adjustment. The

wrist-pin 64 is adjustable radially on wheel 8,

and a radially-adjustable counterweight 66 is provided on the opposite side of wheel 8.
