Specification of Reissued Letters Patent. Reissued Mar. 19, 1912.

Original No. 872,617, dated December 3, 1907, Serial No. 336,279. Application for reissue filed February 26, 1909. Serial No. 480,289.

To all whom it may concern:

Be itknown that I, IRA E. FLETCHER, a citizen of the United States, residing at Montello, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Rotary Heel- Seat Makers and Counter-Founders, of which the following is a specification.

The endeavor at present in shoe factories is to secure speed, uniformity and perfection of work, and accordingly I have invented the hereinafter described heel-seat maker and counter shaper or pounder for accomplishing the objects mentioned with relation to the heel part of the shoe.

In carrying out my invention I provide 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 proceeds with great rapidity so that the heel-seat is made quickly and with entire uniformity throughout all parts thereof. The rotary hammer not only gives great idity of blows butkeeps the machine in lance so that it can be run at a high speed with great uniformity of operation.

In the drawings: Fi re 1 represents in side elevation and part y in section a preferred embodiment of my invention; Fig. 2 is a top plan view thereof.

On a suitable pedestal 1 is mounted a frame or head-piece comprising opposite supporting walls 2, 3 having a cavity or channel 4 between them and supporting a shaft 5 provided with fast and loose pulleys 6, 7. Centrally secured to said shaft is a transverse hammer-head 8 and at the opposite sides thereof are eccentric straps 10 whose rear arms 11 are pivotally connected at 12 with a depending hammer or pounder 13 whose head 1 1 curves forwardly in position to operate against the vertical counter portion 15 of a shoe 16, the upper end of said pounder 13 being pivotally mounted at 17 in adjustable blocks 18. The hammerhead 8, which as shown has a plurality of striking ends extending radially in different directions from the axis of rotation, rotates in the direction of the arrow Fig. 1 and its striking faces are eccentrically curved as clearlyindicated 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.

Preferably, and as shown, the relative construction and arrangement of the heaters 8 and 13 is such that the rotary beater 8 engages the bottom of the shoe with a wiping action directed from the shoe edge inwardly while the reciprocating beater 13 delivers blows against the side of the shoe at its edge. The timing of the action of the eccentric straps 10 which operate the pounder 13 is such with relation to the revolution of shaft 5 to which is secured the pounder 8 that the two pounders strike the shoe substantially simultaneously, the blows of the side beater 13 substantially registering with the action of one of the striking faces of the pounder 8, while the action of the other striking face of-the pounder 8 alternates with the blows of'the side beater 13, with the result that the blows from the reciprocating beater 13 alternate with the wiping contacts of the striking faces of the ro-- tary pounder 8.

The shoe and its contained last are mounted on any suitable kind of work rest such for instance as a post 22 operated by a foottreadle 23.

It will be understood that I have shown my invention in its simplest form and have omitted many of the minor constructional details in order clearly to show the essential features. Preferably a work positioning plate or rest 24 is secured to the front lower end of the head and is apertured at 25 to permit the hammers to operate on the shoe and the rest has an angular bend as shown in Fig. 1 to form a seat or rest-cavity for receiving the shoe and aiding the operator in properly positioning 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 upper materials and the counter about the heel-seat and at the same time a slower series of lateral blows is delivered against the side of the shoe, the result being that the upper materials and the 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 portions of the hammer, or two-hammers-in-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 oblique ended hammer serves to crush down and form the leather while the middle portion and end 21 press the leather hard down and set the tacks in solidly as required in the best grades of work. By shifting the hammer 13 slightly, its angle and character of blow may be changed although the character of the blow is regulated mostly by the position in which the operator holds the shoe and the pressure applied through the footlever, this being especlally the case as to the vertical pressure, or blows from the hammer 8.

While I have herein shown and described my invention in its preferred embodiment I wish it to be understood that I am not limited to the precise details shown.
