Application 'filed September To all whom it may concern:

Be 1t known that I, IRA E. l nn'rcnnn, a

citizen ofthe United States, residing at Montello, in the county-of Plymo-uth and State of Massachusetts, have invented an Improve ment in Rotary Heel-Seat Makers and (lounter-Pounders, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The endeavor at present in sh'oe factories is to secure s eed, uniformity and perfection of .work, an accordingly I have invented the hereinafter described heel-seat maker and counter shaper or pounder for accom plishing the objects mentioned with relation to the heel part of the shoe.

In carrying out my invention I rovide a rotary hammer-for pounding and shaping the heel-seat, and in connection with said rotary hammer I provide a pounder or shaper for the adjacent vertical portion of the counter, said counter hammer moving preferably at a slower speed than the rotary heel-seat hammer. The latter hammer .is so, constructed that its initial blow is light, followed by a smoothing movement and then a hard striking or pressing blow. The result is that the comparatively stiff bends of leather which form the heel-seat are neatly bent over and smoothed down,,- the light blow serving to bend them down and push the folds forward gently, While the harder pressure draws the leather of the counter, and sets the tacks solid at the same time. This operation pro ceeds with great rapidity so that the heelseat is made quickly and with entire uniformity throughout all parts thereof. The rotary hammer not only gives great ra idity of blows but keeps the machine in balance so that it can be run at a high speed with great uniformity of operation.

In the drawlng Figure 1 represents in side elevation and artly in section a preferred embodiment of my invention; Fig. 2 is a top plan view thereof.

On a suitable pedestal 1 is mounted I a comprising opposite supframe or head-piece porting walls 2, 3having a cavity or channel .4 between them and supporting a shaft 5 Specification of Letters Patent.

ate against the vertical counter portion 15 of a shoe 16, the upper end of said poundcr 13 1 being pivotally mounted at 17 in adjustable l blocks 18. The hammer-head 8 rotates in the direction of the arrow Fig. l and its forward revolving end is ccccntrically curved as clearly indicated at 19 so that the forward engaging portion 20 is at a shorter radial distance from the center 5 than the rear or following end 21 The shoe and its contained last are mounted on any suitable kind of jack such for inhead 14 curves 'l'or\ v:i.rdly in position to operdle 23,

It will be understood that I have shown my invention in its simplest form and have omitted many of the minor constructional seat or rest-cavlty for engaging the shoe and the same.

In use the ,operator'places a shoe on the post 22 and raises the same with the foot lever into position as shown in Fig. 1 whereupon the rapidly rotating hammer- 8 delivers a series of quick blows on the projecting edges of the leather and counter about the heel-seat and at the same time a slower seeside of the shoe, the result being that the leather and counter of the shoe are rapidly worked into correct position and given the superior formation and shaping which are desired. The rotary hammer not only does its work with great speed but its movement is very uniform inasmuch as the opposite ortions of the hammer or two-hammersin-one balance each other and also aid by their centrifugal force in giving a precision and uniformity of movement. The shorter end 20 of the obli ue ended hammer serves to crush down anr form the leather while the middle portion and end 21 ress the leather hard down and set the tac s in solidly as required in the best grades of work. By shifting the'hammer 14 slightly, its an- 1 gle and character of blow may be changed, althougir the character of the blow is regulated mostly by the osition in which the l operator holds the s 0e and the pressure stance as a post 22 operated by a foot-treadetails in order clearly to show the essential aiding the operator in properly positioning ries of lateral blows is delivered against the Patented Dec. 2,1907.

-Wish it to be understood that I am not limited to the precise details shown.-

iiaving described my invention, what I desire to secure by Letters Patent is:

l. A heel-seat maker, comprising a heel rest, a rotary liammerabove said heel rest for delivering a series of swinging blows to form the heel-seat, combined with a swinging side pounder in the same vertical lanewith said hammer below and back of the hammer for simultaneously pounding the counter immediately next to the portion of the heel-seat being crushed down by the hammer, said hammer and pounder being constructed and arranged to strike the leather in directions tending to work the leather forward in the same direction over the edge of the last and inwardly on the heelseat.

the heel-seat, and means for operating said side pourder to deliver a slower ser es of blows than and rotary hammer.

3. A heel-seat maker, comprising a rotary hammer for delivering a series of swinging blows to form the heel seat, a swin ing hammer acent said rotary hammer for simultaneously pounding the counter adjacent said "e l seat, and a connection from said 7 T mmer to said swinging hammer rang the latter by the former.

forward horizontal, sliding,

4..A heel-seat maker, having an angular heel rest to position the heel of a shoe, a transverse rotary shaft mounted approximately vertically above said heel rest, a radially extending hammer mounted to revolve' with said rotary shaft, said radial hammer having the front edge of its outer end beveled and at such a distance from the shaft that when a shoe is in lace, in said heel rest, the beveled end of t e hammer first strikes a light blow which is followed by a crushing pressure of the back ortion of said outer end of the hammer on the heel-seat of the shoe, an eccentric on said shaft, a laterally movable hammer having its striking end opposite the lower portion of said heel rest to strike against the counterof the shoe, and an eccentric strap from said eccentric to said hammer, arranged to move the latter at each revolution of said shaft to-strike a blow against the counter of the shoe.

-5. A heel-seat maker, comprising a heel rest, a shaft mounted transversely above said. rest, a radial hammer fast on said shaft and arranged to-swing across said heel rest for giving a long sliding blow and rubbing pressure aerossthe heel-seat of the shoe, a

swinging hammer pivotally mounted above I said shaft, having its lower end curved forwardly toward said heel rest, and operatin means extending from said shaft to said swinging hammer for simultaneously swinging the latter hammer as the first mentioned hammer rotates.

' In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.-
