pose of temporarily connecting said upperE and inner sole'in the opei'ation of lasting.

The invention consists as a whole in an organized hand-machine, in which are combined a supporting-frame having a handle adapted to be grasped by the operator and provided with a throat or channel arranged to guide staples into the work to which the machine is: presented, a removable staple-holder or chute` arranged to deliver staples to said throat and pro ided with a spring-impelled feeding device or follower, whereby a row of staples on said chute are pressed forward as fast as they are driven, a driver arranged to pass through said throat and eject staples therefrom one at a time, and a pneumatic operating device for said driver, whereby the driver may be forcibly depressed to driveastaple and raised preparatory to driving another staple.

The invention also consists in the combination, with a portable frame and alstapleholder or chute, a driver, rand a driver-operating device carried by said frame, of a pair of pineher-jaws and a fulcrum therefor, said jaws and fulcrum being reiatively arranged, as in a pair of lasting-pinehers, one jaw constituting the throat through which thc staples are driven and the other being movable toward and from said throat, the arrangement being such that the operator can use the jaws in drawing v.the edge of the upper over the bottom of the last, and then, while holding the drawn-over portion of y'the upper in place, can drive a staple through the said combined throat and jaw, and thereby fasten the upper close to the point where it is held by the jaws.

The invention also consistsn certain minor improvements incidental to the foregoing, all

of which l will now proceed to describe and claim.

in the acconipanying drawings, forming a part of this specification,Figure l represents a side elevation of a racking-machine embodying inyinvention. Fig. 2 represents a longitudinal Section through the handle, the nail-guiding throat, and the pneumatic driving mechanism. Fig. S represents aside View, and Fig. 4L. an end view, of the detachable staple-holder or chute removed from the machine.

ln thed'rawings, Ct represents the stapleguiding th roat, which is formed ou or attached to the frame of the machine and projects downwardly theretrom, so that its lower endg,l

in which the staple-chann el a terminates, may be conveniently applied to the surface into which the staples are to be driven, the machine being held by the operators hand and moved about from point to point to drive the staples whereverthcy may be desired.

'c represents the driver, attached to a driverbar c', which is adapted to reciprocate and carry the .driver back and forth in the staplechannel a. To the driver-bar is attached a pistonldpwhich is fitted in a cylinder e, affixed to thelrafme .chaine machine, and is provided with ports ,fi/"done near its lower andv itheothcr near its upper end. Said ports communicate with a valve-cylinder 71., which contains a double puppet-valve composed of two heads n" anda connecting-stellig'. The valvecylinder has an air-inlet 7i; about midway between 'it-spinte, and said inlet is connected by a flexible tube Z with a suitable air-compressor adapted to supply com pressed air to the valvecyli nder 7l..

In the constructies; shown-:in required to press the slide s toward the throat Fig. 1 the chute or staple-holder-isstraight, n, the slide being adapted to move baci; and and the feeding-slide s is provided with rollforth in the arc et a circle on. the segmental chute 'lhr rear end ol the slide iff. made `ers t t', arranged to run the one on the upper wedge-shaped, as shown at s s', Figs. 7 and '8,

and-when thewslidcv is moved back it enters the space between the cars 0 9 and forces-'said ears apart, as shown in Fig. 7, thereby releasing the chute q. The slide s has recesses 17 17, which are engaged by projections 1S '1S on the ears 9 9, the slide being thus held in said ears until the chute is reinserted between them.

From the foregoing' it willjbe seen that the operator is enabled to holdlthe machine in one hand and present the throat a, at any point where it is desirable to estafa'steiiing in the edge of a boot or shoe upper, during the operation of lasting, the fastening being driven by each upward movement of thevalve' of the pneumatic driving device.

I have here shown the throat a formed asy a jaw which is serrated a `ene, side, and `1n' connection therewith I shi wl: a movable jaw 18, which is pivoted at 19 and has an arm or lever 20 arranged to be acted upon by a lever 21,'which is pivoted at 22 to the supporting` frame, said lever 21 being located in such relation to the part 23 of the frame which serves as the handle of the machine that the operator can grasp said handle and move the lever 21 in the direction required to close the jaw 1S upon the throat or jaw e..

24 represents a foot which is attached to the frame of the machine, and is arranged in such relation to the jaws a and 1S that it is adapted to serve as a fulcrum-bearing on the inner sole while the upperris being drawn by saidI jaws over upon the bottom of the inner sole, the relative arrangemcij" e'rtlieia'fvs ct and .i8 and foot 24 being thelsanlie as that of the jaws and foot or fulcrum of an ordinary pair of lasting-pincliers- The operator is enabled by the described jaws and foot to draw thel edge of the upper over upon the bottom of theTsole and then fasten said edge to the innbrisole by operating the driving mechanism, as above described, while the edge is being held 'by the jaws, the fastening being drij'ven through the fixed jaw close to the pointwhere the upper is grasped by the two jaws. [iA spring 25, interposed between the jaws a and 18, normally forces the latter back, as shown.

My invention is not limited to the use of the jaws and foot, andthe machine can be used without the same. lVhen the jaws and foot are not used, the cylinder e maybe utilized as the handle of the machine, in which case the handle portion 23jwill not be required.

The forward portion of the chute q is provided with side pieces 27 27,. nlffl., extend across the slot q and hold the divisions of the chute formed by said slot so that neither can spring away from the other. Said pieces 27 are cut away at their inner sides, as shown in Fig. 4, to permit the legs of the staple to pass them. I. l

Referring tothe construction shown in Fig. l, the latch 3 has a downwaidly-projeeting lller l. on the slide .s lie slide is moved to thesrearff jl. ci the clrnte. Said `rollerI en- -rions points, according to the discretion oi' the operator, and, although I have particularlydescribed its use in` lasting boot and shoe..uppersylidenot limit it to such use, but

may use it tor tackin'guon tap-soles or for :other like purposes.

When the valve o't the pneumatic operating device is at its lowest point, one side ot' j its lower head e' bears on an inwardly-pro` jecting seat or lip /1/ at the lower end of the cylinder 7.-. and prevents any escape of air through. that-'Lend of the cylinder. At the upper end ot' the cylinder is another seat Il?, which co-operates in like manner with the head t" in preventing the escape of air through the upper end of the cylinderwheu the valve is at its highest point. The cylinder 71. is internally reduced in diameter at its upper portion to correspond with the reduced diameter of the upper head il', said reduction being effected `in this case by a lining-tube 713 inserted 'in the cylinder, the upper portf being foi-ined partly in said tube. The seat 7g3 may be omitted', as the valves t' l1I only remain raiseil while the operator holds the le ver m.l u llence the valve t" seldom reaches the seat/1i. tigt im i c. cg represent yielding .buffers or washers in the ends of the cylinder c to cushion the piston as it roaches the en ds of its stroke. 'lhe washer c is annular and serves as a packing to prevent theleakagc ot' air around the drh er-bar` c",
