'WORK-SUPPORT.

Specification of Letters Patent.

Patented Oct. 29,1912.

To all 'LU/1.0m I? may concern Be it known that 1, RONALD F. MoFnnLY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in TWork-Supports, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several iigures.

rihis invention relates to shoe supports or jacks and is shown as embodied in a machine for shaping a lasted shoe to prepare it for the reception of an outer sole.

Features of this invention include novel characteristics of the mounting for the forepart support for the shoe.

Another feature of this invention is found in the construction and arrangement of the shoe support to adapt it to receive a boot or long legged shoe without bending or crumpling the leg portion.

These and other features of the invention will be more fully explained in connection with the description of the machine in which they are herein shown and embodied and will then be pointed out in the claims.

Figure 1 is a side elevation of the jack and of the machine which is of the same general type as that shown in my earlier Patent No. 1,019,067, granted March 5, 1912. Fig. 2 is a front view of the jack; Fig. 3 is a perspective view for the purpose of illustrating the side beater, and Fig. 4 is a perspective view of the forepart support.

The column 2 of the machine has a head 4 provided with bearings in which is mounted a shaft 5 which drives, by means of an eccentric stud, a V-shaped rocker 6. In the front face of the rocker is formed a groove by which is made a sliding connection with a link 8, having formed upon it. or upon a block connected with it, a segment rack by means of which the link can be moved toward and from the center of oscillation of the rocker which is at 10. The rack is engaged for this purpose by a pinion 12 meshing with a segment lever 14 connected with a foot treadle which, as in the machine of the prior application, is a starting treadle and is arranged to be first depressed for throwing in a clutch that drives the shaft 5, and then to be further depressed for adjusting the link relatively to the rocker to vary the length of the stroke imparted to the link.

The link 8 is joined at its front end to a vibrator 15 for the tool carrier 16 in which is mounted the bottom pounding tool 20. The vibrator and the carrier are both mounted on the same pivot or fulcrum 18 and the upper arm of the vibrator extends into an inclosed space in the tool carrier where it is located between two cushions 19, which preferably will be rubber blocks. The ar-- rangement of these cushions within an inclosure in the tool carrier is an improvement over my prior construction in that it protects therubber blocks from the oil and dust which would otherwise deteriorate the rubber. rihe bottom pounding tool will preferably be mounted in its carrier and actuated to operate substantially as in the earlier machine.

The shaft 5 is provided with a cam 25 adapted to operate a vibrator 26 which is fulcrumed in the machine at 28 and connected to a tool carrier 30 on which the side beating tools are mounted. A spring 32 normally holds the vibrator and the tool carrier forwardly with relation to the fulcrum 28 and maintains the vibrator out of contact with the cam 25. rlhe tool carrier 30 is at its forward end forked to extend under the bottom pounder and has laterally projecting ledges 34 arranged between a supporting member 35 on the head 4 and a plate 36 at the lower end of a spring pressed plunger 38. rilhe ledges 34 are inclined as appears `clearly in Fig. 1, so that as the tool carrier is moved forwardly, the side beaters are given a componentof upward movement which causes them to work the upper toward the edge of the last. rThe side beating tools 40, of which one is arranged on each side of the bottom pounder, are swiveled upon the tool carrier 30 to turn about horizontal and upright axes. as shown, to enable them to adapt themselves to the contour of the shoe. The tool carrier has stop faces at 42 which limit the tipping movement of theside beaters about their horizontal axes and the beaters are formed with downwardly and backwardly receding faces.

The shoe support is mounted for inward and outward adjustment at 50 and for vertical adjustment at 52. The post extends through an eye 54 which limits the movement of the shoe support away from the machine. The post terminates in a fork 55 to the outer ends of which are pivoted hangers 56 with which the side plates 58 of the jack carriage have sliding engagement. The side pla-tes support a front cross-bar 60 which is held in adjusted position thereon by a locking pin 62 taking into o-ne of several recesses in one of the plates 5S. The cross-bar 60 is forked or laterally recessed in its front side to receive an adjusting nut 64 upon the toe post 65. provided, as shown in Fig. 4, with a head having an arc-shaped guiding portion 66 curved about a center located in substantially the plane of the bottom of a shoe rested upon the shoe support. Upon this guiding surface is mounted a block 68 with which the toe pad 70 is connected by a transverse pivot G9. rllhis mounting for the to'o pad permits the pad to adjust itself angularly in two directions to adapt itself to the shape and position of the shoe being supported, and enables the pad to give firm support to shoes made on lasts of widely varying shapes. The forepart rest is arranged relatively to the heel rest to support the shoe with its forepart in a substantially higher plane than the shank so that, as the shank is reached inthe progress of the poundingup operation. the side of the shank engages a lower portion of the receding face of the side beater and permits the beater to move under the influence of spring 32 forwardly away fromv and out of operative relation to its actuator 25 so that the beating operation is discontinued at the shank without special' attention from the operator. Of course the beating operation can be continued if desired, by pressing the shoe further in under the bottom pounding tool. rlihe side beating operation can be resumed at any time,

asfor example when the heel is reached, by such an inward movement of the shoe.

The heel rest comprises a pin to enter the usual pin hole in the last. The pin is pivotally supported upon a post 76 which rises from a yoke 78, see Fig. 2. The upper ends of the arms of this yoke are formed to have sliding engagement with the side bars 58l of the jack and the yoke is provided on one of said end portions with the locking pin 80 to engage a hole in the side bars for securing the heel support in adjusted relation to the forepart rest. The arrangement by which the heel post is connected to the side bars by a yoke enables the boot to be applied with the leg extending between the arms of the yoke and the post without crumpling the leg portion of the boot.

The novel features of the machine herein shown for operating upon the shoe carried by this work support are not claimed in this application but are claimed in another application filed by me, Ser. No. 523,072, filed The upper end of the toe post is.

Oct. 16, 1909, for improvements in shoe forming machines which is a continuation of this present application as to subject matter which is common to the two applications.
