` SHOEMAKERS JACK.

Application filed July 6, 1920, Serial No. 394,329.

To all whom t may concern.'

Be it known that I, JAMES ASTRANGE, a citizen ofthe United States, residing at Ellensburg, in the county of Kittitas and State of Washington, have invented a certain new rand useful Improvement in Shoemakers acls, of which the following is a specification.

My invention relates to improvements in shoemakers Vjacks and the object of my invention is to 'provide a jack comprising a vertically adjustable telescopic standard, the male member of which is rotatably mounted within the 'female member thereof and adapted to be releasably engaged therein in any desired position. l.

Anotherobject is to provide a telescopic and rotatable shoemakers jack embodying a removable arm adapted to-be disposed on the tongue or upper end ofthe said jack, the said arm comprising a relatively fixed socket member and a relatively movable member which is mounted for rotation on its own axis in the said socket member and which is further adapted to be clamped in any desired position in the said socket member.

Al further object is to provide a shoemakers jack ythat embodies simplicity, economy and durability in construction, tha-t is positive and efficient in operation and that will not readily get out of order.

With the above and other objects in view the invention consists of the novel construction7 adaptation and combination of parts as will be hereinafter described and claimed.

I accomplish these objects by devices illustrated in the accompanying drawings wherein Fig. ,1 is a side eleva-tion, partly in vertical section, of-a shoemakers jack constructed in accordance with this invention.

Fig. 2 is a view in horizontal section, substantially as shown on a broken line 2, 2 of Fig. l;

Fig. 3 is a view in horizontal section, substantially as shown on a brokenl line 3, 3 0f Fig. 1.

Fig. 4 is a front elevation, partly in vertical section, showing the means by which the upper end of the lifting rod is attached to the standard, and with the removable arm in adjusted position.

Fig. 5 is a plan view withthe removable arm in an adjusted position; and

said standard. Spaced at convenient intervals, transverse holes 8 are provided in the female member into which fits a pin 9, said pin carrying the Yweight of said male member by fitting into slots 10 or 11 provided in the lower end of said male member. A foot lever l2 isV secured to said female member by a pivot 13,.'and to a lifting rod 14 by a pin 15. The'upper end ,of said lifting rod 1 is bent to form a loop 16 which lits' under a collar 17, said collar being adjustably secured to the male member 7 by means of a set screw 18. Said malle member terminates in a tongue 19 to which either a last 20 or a removable arm 21 is mounted by means of a rectangular slot 22. Said removable arm is composed of an offset member 23 and a longitudinal member 24, revolvably mounted therein by a reduced end 25 secured by a set screw 26. The end of a hook 27 passes through said longitudinal member, secured to the hook end of which is a spiral spring 28 to `which a cord 29 is fastened. Said cord passes around the last or shoe and is secured to the other end of said hook substantially as shown. The longitudinal member 24 terminates in a tongue 30 to which a last is secured -in the usual manner. j

VVith'the aforesaid objects inview, and with reference to the drawings, it will be seen that instead of the Shoemaker having to contortv himself into awkward, unnatural and uncomfortable positions While engaged at his trade, with the device herein described, he can readily adjust his work to suit his comfort and convenience. This is accomplished by sliding the stand along the floor to any position desired for convenience of light, heat, ventilation, etc. Then by operating the foot lever and inserting the pm 9 in the hole 8 at the desired height the device is ready for use in working on the soles of foot Wearing apparel. It will be seen that by providing two slots at right angles to each other in the 'lower end of the'male member 7, the workman may readily turn the shoe, upon which he is working, to vany one of two different positions by lifting the male member by means of the foot lever and its associated parts until the slot clears the pinv and revolving same to the desired position. When sewing or working on the upper partpof -a shoe the arm 21 replaces the last 20, which is shifted to the tongue 30,

and the shoe or other foot wearing apparel is seeurelyheld on the last by fastening the cord around same at the desired tensions,

and the work is revolved vertically by use Y of the set screw 26 and horizontally by turning the male member 7 within the female member G tothe desired angle.

F rom the above description takenin connection with` the accompanying drawing, the advantages Vof the construction and .of

the. method of Aoperation of my shoemakers stand willl be readily lapparent -to` those skilled inthe art to which the invention relates, but, While I have described .the4 principle of zoperation of the 'invention together with .the device which I now consider to be the best embodiment thereof, I desire to `have it Yunderstood .that the stand shown isv merely illustrativeand Vthat 'such changes may be made vas are within the scope of the following claims.v

f 1; A jack comprising a base, a telescopic standard consisting of `male andfemale members, a pin removably positioned at different heights transversely of the female member, the lower end of the male member Y having crossed slots for selective seating on said pin, a collar adjustably connected to the malemember, a foot'lever pivoted tothe female member, a link rod connection between the collar and lever for elevating the main member, and a last carried bythe other end of the male member. f

2. A jack comprising a base, a telescopic K standard consisting ofl male and female lar, and alast carried by the other end ofV the male member.

In witness whereof, I hereunto subscribe my namethis 25th day of June A. D. 1920.V
