Application filed June 20, 924, Serial No This invention is concerned With supporting or positioning the Workor a tool in op: erations on shoes or parts thereof, and particularly relates to the supporting of shoes when on their lasts by a projection, knovvn as a last-pin or spindle, which enters an opening in the last. Shoes are commonly supported in this manner for many operations where pressure is to be applied. Ainong'these operations may be given as examples, heel-attaching and sole-lay ng or leveling. Sometimes the last-engaging spindle is utilized to guide a driver for inserting a nail or other fastening to hold a heel temporarily upon a shoe, a hole being bored through the cone of the lastfor this purpose. 1 This is as illustrated in British PatentNo. 177,015, Haldinst'e-in, March 23, 1922. r Iii-attaching heels in the manner indicated above, there is sometimes difiiculty in securingthe heel firmly, owing to its tendency to turn "about the "axis of the fastening. f The removal of this difliculty is oneof'th e objects of the invent on, and for; thispurpose We provide a support having a last-engaging projection, inwhich a plurality" of tools, as

'sides'of the-axis of said projection and pardrivers, may operate together at opposite "a'l lel thereto'to effect the insertion of a plurality of fastenings .side by side in the'heel. By the insertion of a plurality of such fastenings, the heel can be held against'any twisting itendency Withouturidueif any, en'- largement ofth'e hole in the last, since the drivers and driver and fastening-guides may be of less diameter than when asingle fastening is used.

When 'such 'a device is, employed upon heel-attaching mac'hinesof the usual character, thefact that thel'ast must be placed upon and removed from a last-entering spindle, which, to guide the fastening or fastenings, must be approximately of the full depth of therear ofthe last, requires a clearance bet-Ween the'upper and lovver Workengaging niembers of the machine, that is substantially greater than thatneeded' when inside attaching is being' performed Without a last in the shoe. This clearance may be greater than the machine is designed to provide, and With the correction of thisdefect as one of its objects, this invention furnishes a support having upper and lower sections 721,193, and in area Britain July 24', 1923.

I pivoted together, i the upper section carrying the last-engaging projection. This permits the last-entering spindle to be swung out'to a point atgivhich theopera-tor has free access to it, for the purpose ofapplying and removing the lasted shoe.- I

One form of Work-support .or'jack embodying our invention is illustrated in the accompanying drawing, in which- "Fig.1 is a central, vertical section through the. improved support,.the parts being, in Work-receiving position; I I f Fig. 2 is a partial vertical section with the elements innailing position; and

Fig. 3 is a horizontal section on the line 33ofFig.2.1"1

This organization may be employed, for 'eXample,*in such machines as those. disclosed in United States Patent No. 1,195,134, Gouldbourn, 'Aug. '15, 1916, and No. 1,269,- 654, Standish, June 18,1918. At 10 appears the top of a jack-base, having reciprocating Within it, a driver-actuating member 12. Mounted inthe upper extremity of the base is'the lower section 1 1 of thebody-portion of the jack, and pivotedgat 1,6 to this isthe upper section 18of the j ack-body. Opposite surfaeesQO, 20 upon the adjacent ends of these sections contact to hold said sections is normal. axialjalinement, this being the na1l-dr1v1ng relation. .The pivotal connection permits the upper section to be swung outwardly, asindicated in Fig. of-the drawing, to an extent limited by contacting stop-surfaces. 21 associated ivith the pivot. to a position convenient for the application of the Work to the jack. j Botlrsections are tubular, the upper being closed at the topby a head 22. Rising from this head is a projection 24c,'furnishing a spindle adaptedto enter the pin-hole of a last. Through the spindle are a plurality of longitudinal passagesiof which two are illustrated, .these being parallel to the axis, at opposite sides thereof, and receiving operating. tools,1as drivers 26. The drivers are held by some s'uchfastening device as a pin '27, passing member 28 movable in the axial bore of the section 18. This connection of the drivers to the plunger is preferably such as to give some lateral play, to better allow the drivers through horizontal boresjin them, ithin sockets formed in the end-and at opposite sides of the axis of a plunger or carrler V spindle.

to aline themselves with the passages in the The bottom of the "plunger 28 is divided at 30 "to receive the pivotal connection of a link 32 articulated at its lower ex-f tremity to a divided portionof aplunger 34 movable in the boreof the 'jaclnsection 14.

The upper pivot-pin of the link maybe re- 7 duced at 36 and enter a groove38 inthe wall of the section 18, this preventing the plungers from rotating, maintaining the ahnement-of the drivers with the spindlepassages. The plungerfliahas a depending stem 40' passing through a contracted opening in the section 14 and contacting with the actuating member 12. The plungers] and drivers are 7 held yieldab-lyj in theirdepressed positiomat which the upper ends of the drivers are below the tops of the spindleepassages, by. a spring 42 surrounding the plunger 28 and the drivers, this spring abutting at one end against a shoulderui aon the plunger, and at the opposite end against the inner side of the head 22.

V In using the jack, the section 18 is swung forward to the position appearing in Fig l, at which it is clear of the abutmentmember which exerts pressure upon the heel to hold it in place for nailing. Nails are now sup plied to the spindle-passages, their heads resting upon the upper extremities of the drivers,and a last-ed shoe is placed upon the spindle, which enters the hole in the rear Gib portion of the last, passingthrough this into proximity with the heel-seat, the crown ot the last resting upon the upper surface of the head 22. The section 18, with the jacked shoe, is then "returned to its vertical .position, and the'machine started, to cause the actuating member 12'to rise, this, by its contact with the stein 40, elevating the plunger 34, which," in turn, carries up the plunger 28 with the drivers, forcing the nails through the heel-seat of the shoe into the heel, to fixthe latterin place.

Having describedour invention, what we claim as new'a nd desire to secure by Letters Patent of the Unit-ed States is;

V

8. A support comprisinga body-portion havinglow-er and upper sections pivotally connected, the" upper section'b-eing provided vwithfa tubular "projection arranged to enter an'opening in a last, co-operating plunger-s movable 1n thesections, a drlver mounted -upon thecplunger in the upper section and extending into the projection, and means for actuatlng the plunger of the lower section. gt.
