COMBINATION JACK FOR TWO LASTS Filed March 7, 1933 4 Sheets-Sheet 4 Inventor Patented Feb. 13, 1934 UNITED STATES PATENT oFFIcE 5 Claims.

The present invention relates to a jack for supprovide a shoe repair stand to hold two lasts and repair two shoes, during the needed repairs on both shoes, while holdingv the tools to do the operation, thereby saving considerable labor.

A further important object of the invention resides in the provision of an apparatus of this nature which is simple in its construction, comparatively inexpensive to manufacture, strong and durable, fairly efiicient and reliable in use and operation and otherwise well adapted to the purpose for which it is designed.

Another important object is to provide a stand or apparatus of this nature, the height of which may be adjusted and which includes means whereby the lasts may be simultaneously hammered from the sockets in which they are supported,

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

Figure 16 is a perspective view of the tool tray or bench.

Referring to the drawings in detail, it will be seen that the numeral 5 denotes a base which may be screwed or otherwise fastened to the floor, as is indicated at 6. Numeral 7 denotes a hollow standard or column threaded into the base and rising therefrom. A tubular bar or post 8 is telescoped into the upper end of the column 7 and is held in the desired adjusted position by means of set screws 10. From the upper ends of this post 9 there diverge upwardly and outwardly brackets 11 terminating at their upper ends in blocks 12 having sockets 14 tapered downwardly to receive the shanks of conventional lasts 15. Between these bracket arms and socket blocks there is mounted a bench or Work plate 16 with suitable receptacles 17 or the like for tools and working materials. Angle irons 18 are fastened under the side edges of this plate 16 and are of a V-shaped formation in cross section and are secured by screws or the like 19 to the blocks 12, as indicated to advantage in Figure 10. In the brackets 11 are rockably mounted hammers 20 by means of pins 21. Each hammer is of an elongated construction terminating at one end in a head 22, the bottom of which is provided with a socket 23 in which is mounted a pin 24. A spring 25 is engaged with the pin and engaged as at 26 on the post to hold the hammer in down position. The other end of the hammer is bifurcated as indicated at 2'7 and has a pin 28 between the furcations. An elongated rod 29 has a pair of hooks on opposite sides of its upper end, as indicated at 30, engageable with the ends 28. A yoke 31 is swiveled on the bottom end of the rod. On one side of the lower portion of the column 7 is a vertical slot 33 through which extends a pedal shank 34 terminating in a pin 35. This pin 35 is adapted to project through a resilient elastic-like plug 36 which may be inserted in any one of a vertical series of openings 3'? in the other side of the column opposite to the slot. This series of openings 37, of course, takes care of any adjustments which are made between the post and the column. By pressing down on the treadleplate 40, of course, the hammers may be swung so as to knock the two lasts out simultaneously. In order to hold the pin 35 in place, I utilize the spring 41, a washer 42 1 and a cotter pin or the like 43, this assembly being clearly illustrated in Figures 10 and 11. It will be understood, of course, that the yoke 31 straddles the pedal shank 34 and is attached thereto by a pin 44.

It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. An apparatus of the class described including a hollow post, a pair of bracket arms diverging upwardly from the post, socket blocks in the brackets having last receiving sockets therein, last ejecting hammers rockably mounted in the brackets below said socket blocks, and means extendingthrough the post to actuate the hammers.

2. An apparatus of the class described including a hollow post, a pair of bracket arms diverging upwardly from the post, socket blocks in the brackets having last receiving sockets therein, last ejecting hammers rockably mounted in the brackets below said socket blocks, means extending through the post to actuate the hammers and springs associated with the hammers to normally hold them in inactive position.

3. An apparatus or the class described including a hollow post, a pair of bracket arms diverging upwardly from the post, socket blocks in the brackets having last receiving sockets therein, last ejecting hammers rockably mounted in the brackets below said socket blocks, means extending through the post to actuate the hammers, a column, said post being telescoped in said column, and means for holding the post in adjusted position in the column.

4. An apparatus of the class described including a hollow post, a pair of bracket arms diverging upwardly from the post, socket blocks in the brackets having last receiving sockets therein, last ejecting hammers rockably mounted in the brackets below said socket blocks, means extending through the post to actuate the hammers, a column, said post being telescoped in said column, means for holding the post in adjusted position in the column, said means extending through the post also extending through the column, and a pedal mounted in the column and connected with said means for actuating the same.

5. An apparatus oi the class described including a hollow post, a pair of bracket arms diverging upwardly from the post, socket blocks in the brackets having last receiving sockets therein, last ejecting hammers rockably mounted in the brackets below said socket blocks, means extending through the post to actuate the hammers, a work bench plate, and angle irons under the side edges of the plate of substantially V-shaped cross sectional formation and fixed to said block.
