I i mpro v'cments.

State of Massachusetts, have invented certam new and .useful'lrnprove'ments in Lasting and Tacking Machines for Shoes, [of which .the following is a specification.

This invention has relation to machines for tacking the edge of an upper to an inner sole of a boot or shoe, and'it has for its object to providecertain improvements in the mechanism for automatically grasping the upper, so that the operator can draw the upper taut about'the last, prior to the actuation of tlieta'cknpplying 'nozzle by the shoe to effect the operationof the machine. Provision is also made for causing the tack to.

be driven to a greater or lesser depth, as cirby shifting the range of the driver, and is hereinafter described in detail.

Referring to the drawings, which illustrate one embodiment of the invention, to the de-. tails of construction of which, however, the

invention is not limited, Figure 1 represents in side'ele'vation a machine embodying my Fig. 2 represents a portion of the machine, and illustrates the jaws of thdpincers in their open position. Fig. 3 represents a similar viewand shows the jaws of the pincer closed upon the upper. Fig. 4

represents a section through the upper portion of the pincer. Fig. 5 represents the movable catch on the Fig: 6 is a front elevation of the device by which the driver-bar may be shifted longitudinally.

For the details of construction of the tacking mechanism, and the mechanism by means'ofwhich the driving mechanism is caused to drive a-single tack when the nozzle is raised, as well as the mechanism for feed-' ing the tacks to thedriver, reference may be had, to the patent to E. Woodward, No. 389,275,'dated Sept. .11, 1888; and also to my oo-pending application, Serial- No.

the tack-deli vering Qn the drawings,

The

member or nozzle is indicated at 10.

driver. 100 is actuated by a cam 12' on a shaftgll, the latter being provided with a lo'os'efpulley 13 containing a clutch 14. The" 'movement of the clutch is controlled by the i i-140 and trip-mechanism, hQ in This is accomplishedpincer for engaging so as to Fig.1, by which when the nozzle 10 is forced ing this operation is not fully illustrated or described, as it forms no part of the present invention, being illustrated in detail in the Letters Patent of Woodward hereinbefore referred to. v

In order that the upper may be properly drawn about thelast into the inner solo, .a pincer is provided and is arranged in close proximity to the nozzle. Preferably one of thepincer members is apertured so that the nozzle may extend therethrough, in order to deliver a tack in properv relation to the stretched portion of the upper that is laid over the edge of the inner sole.

' In conjunction with the incer, mechanism is provided by means of w ich the advent or presentation of the shoe to the pincer causes the jaws of the pincer to close automaticallyupon the edge of the upper which is inserted between them by the operator. The operator may then draw the upper taut over the last and wipe the edge thereof down over the edge of the inner sole, and with practlcally the same motlon move the shoe so as to engage the'nozzle and lift it sufliciently to trip the mechanism by means of which the driver is caused to drive a. single tack or fastenerinto the Shoe.

In my copending application hereinbefore referred to, the incersare caused to close upon the u' per y the engagement of the shoe with a eeler'loeated so as to project below or beyond the jaws of the pincer, but according to the present invention, the simple movement of the incer itself effects theautomatic closing oi the jaws upon the work, this movement of the pincer being substantially in the lines of movement of the nozzle.

The pincer consists of twomembers 17 18, which are ivoted together intermediate of their ends y astud 19. Said members are provided with the jaws a 'and b, which are serrated as shown toengage the upper firmly revent it from slipping between them. Tl ie member 18 is with awipin the edge oft e stretched upper may be laid by the operator, prior to, the insertion of a tack through the upper.

further provided surface c-by means of which flat over the edge of the inner sole. The

member-.18 is extended rearwardly as at 20, and is pivoted u on astud 21, projecting from the head'of t e machine. A spring 22,

connected to the extension 20 of. the member- .to automatically close. the jaws upon the workwhen' ermitted. The tension of the spring may evaried by an adjusting screw 25. The nozzle 10 extends into a slot 26 formed in the member 18 and in the Wiping surface 0. v

31 indicates a hooked'la'tch which extends through an aperture 29 in the top of the member 17, and the hook of which is adapted to engage a movable'catch30, mounted to slide in the guideway formed in the said member 17. The hooked latch 31 is bent around the driver bar 100 and is connected to an ar 33 on an upright shaft 34, journaled in abearing 36 formed on the head of the machine. To the upper end of the rock-shaft 34 is connected another arm 35, held against the rear face of the cam12 by a spring 37.

The said rear face of the cam 12 is formed with a bunch or rojection for rocking the arm 35 and there y rocking the shaft 34 to move the hooked latch 31. The catch 30 is provided with a member 28, pivoted thereto and held in alinement therewith, by a spring 27. When the jaws of the pincer are open, this member 28 lies above. the feeler 26, which is fulcrumed upon a stud 40 and which is connected to the member218 of the pincer by a screw 41. The stud 40 is secured in any immovable portion of the head', so that when the pincer is moved. upward bodily, the feeler 26 is caused to swing upward about said stud 40, so as to engage the member 28 and lift the catch 30 against the tension of, aispring 43 so as to disconnect the catch from the latch 31. This allows the spring 24 to force the 11 per end of the pincer 17 away from the late 31 but as the movement is not sufficient. to-entirely disengage the pincer and the latch, the

latch may, u onlsubsequent movement, advance under t e catch 30.

In practice, theoperator presents a shoe to the machine when the parts are in the position shown in Fig. 2. The edge of the u per is inserted between the serrated aws o the pincer, and the shoe ismoved upward so as to raise the pincer and cause the tri ping of the latch from the catch, and al ow, the spring 24 to close the aws of the pincer upon t e uplper. The operator is then .able to draw t e upper around the last and lay it .upon the inner sole. When this is being accomplished, the operator is moving the shoe upward until. it comes in contact with the nozzle and lifts it to set in motion the tacking thereinto.

mechanism. After one tack is driven, the

' machine stops automatically.

The closing of the jaws causes the member 28 to swing away from the member 26, thus permitting the catch 30 to be drawn'dow'nwardly upon the end of the latch 31 by the spring 43.

During the rotation of the shaft 11, the arm 35 rides off from the bunch or projection on the cam 12, and the latch 31 moves forward so that its hook'sli s under the catch 30 and as the shaft comp etes its revolution, the projection or rise. forces back the arm 35 so as to rock the shaft 34 and draw the hooked latch and the catch to the rightso as to open the pincer and hold it in'open position and as the shoe is moved downward by the operator, \the feeler 26 drops and the member 28 slips into position above it. From this description,'it is apparent that the operator may manipulate the upper as much as he desires by the aid of the pincer to draw said upper taut about the last and lay it properly, over the edge of the inner sole, before he sets the machine in motion to effect the driving of the tack.

It will be understood that the shoe is supported upon a jack 50, and that'inechanism which is not shown is employed, by means of which the operator may raise and lower the jack to just lts proper position, and is swung by foot power toward and fromthe standard of the machine, so as to move'the work longitudinally of the horizontal portion 20 of the gripper member, as well as vertically 10p transverse to the sole of the shoe, and sub- 5 stantially in parallelism with the plane of the sole. To accomplish this, the portion 20 is provided with a slot 201, through which the stud 21 extends. Theipincer member 18 is provided with a bunch or cam' portion 23,

which is adapted to engage the stationary portion 32 of the machine or tack-guide, as the said member swings upward. The effect of this is to 'drawthe pincer as a whole tension of the spring 22, so that t e wiping surface 0 on the pincer wi es the upper over the-edge of the inner so e with a drawing stroke. The spring 22 o erates not only to swing the pincer bodily ownward but also longitudinally of theportion 20 a 'ainst the 5 to moveit to the right in 2, as it moves downward.

In Figs. 1 and 6, an-arrangement is shown by means 'of which the operator can adjust the driving mechanism so as to fully embed 12 the tacks in the work or drive them partially cam 60 which is actuated by the cam 12 is provided with guides 61 62, in which is It will be seen that the path I mountedla slide. 63. Said slideis provided the other so that by moving the slide 63 to one side or the other, the driver bar 100 may be raised or lowered relatively to the cam 60.

By this means, the bar may beadjusted so that it will fully embed the tacks in driving them in theshank and forepart of the sole, or drive them but partway, as in the case of the heel.

The tack-feeding mechanism is not described in detail as it is set forth in my copending application, Serial No. 152,326 filed concurrently herewith.

Having thus explained the nature of the invention; and described a way of constructing and using the same, without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, I declare that what I claim is 1. A machine for lasting boots and shoes comprising a movable pincer, andmeans for causing said pincer to automatically grip the upper on the movement of said pincer by a shoe. l

2. A machine for lasting boots and shoes comprising a movable pincer, and means rendered active by the inovingof the pincer due to the engagement of a shoe therewith for automatically causing the. pincer to grip the upper .ol' ash'oe presented thereto.
