Application tiled August 31, 1894. Serial No. 521,838.

(No model.)

To all whom t may concern:

Be it known that I, THEODORE A. ME1TZ,of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Shoe-Repairing Jacks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in shoe repairing novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure l is a vertical longitudinal section of my complete invention. Fig. 2 is a cross section taken on the line xof Fig. l. Fig. 3 is a bottom plan view of the detachable last rest. Fig. 4 is a plan view of theupper end of the jack. Fig. 5 is a top plan view of the pivotal portion of the jack; and Fig. 6 isa side elevation of the upmetal lastin position thereon.

The object of my invention is to construct a repairing jack in such a manner that the same can be adjustedin any and all -positions necessary for a perfect repairing of boots or shoes, the several parts of which the same is composed being constructed and made adjustable in a manner as I shall now describe. Referring to the drawings, 1 represents a 'fixed base which is usually secured to a bench and formed in the receives the lower in any suitable manner, same is a socket 2 which reduced end of a movable vertical member 3 whereby the latter is permitted to be turned within said base. Formed in the reduced lower end of the member 3 is an annular groove 4t which receives the projecting end of a thumb screw 5 carried by the fixed base 1, which as clearly shown in Fig. 1 allows the member 3 to turn, but prevents the same from being withdrawn from said base. Movably secured between the forked upper end of the movable member 3 is the upperl end of a movable arm 6, the two parts being united by a bolt 7; and formed integrally with said arm is a supporting base 8 which is adapted to be moved to and from the bench.

9 represents a socket which is formed in the casting that composee the arm 6 and base jacks and consists inthe S, and which receives the lower reduced end lO ot' the'coinbined detachable and adjustable post l1, the two parts being so adjusted and held in position by the thumb screw 12. The upper end of the post 11 is provided with flanges 13 between which a suitable last 14 is placed, and projecting from the solid portion lbetween said flanges 13 is a pin 16 which passes into said last and temporarily secures the latter in position as clearlyshown in Fig. 1. 17 represents a detachable last rest the lower end of which is provided witharounded portion 18, semicircular resting portion 19 and a neck or narrow portion 2O connecting said semi-circular portion and rounded portion; and formed in the upper end of the post 1l is a rounded cavity 2l which receives the rounded portion 18 of the last rest, a semi-circular shoulder 22 upon which rests the semi-circular portion 19 of said rest, and

a space 23 communicating with the cavity21- for receiving the neck 20 also of said rest, whereby, when the said rest is in its position as shown in Fig. 1the same is held secure to said post and yet easily detachable. Formed on the opposite edges ofthe curved upper end of the arm 6, and arranged in line with one another are depressions 24 which receive the engaging ends 25 of the spring actuated pawl 26, the said pawl being movably united between ears 27 forming a part of the vertical member 3; and, interposed between the lower end ofsaid pawl and member is a coiled spring 28 which operates to hold said pawl in its engaging position.

In order to hold the shoe upon the last 1l the usual strap 29 is passed over said shoe as shown in dotted lines in Fig. l, and in order to keep the strap in proper tensionupon the shoe in all positions, it is necessary to form in said jack a continuous passage for said strap. This I accomplish in the following manner: Formed inthe post 11 at a suitable distance from the upper end thereof is a passage 30 which is in communication with a similar' passage 3l formed in the arm 6, the upper end of the latter passage communicating with a rounded depression 32 formed in the upper end of said arm, and communicating also with a vertical passage 33 formed in the vertical member 3, and a similar passage 34: formed in the ixed base 1. Movably mounted at the juncture 34;' of the passages 30 and 31 is a pulley 35 around which the strap 29 passes. The end of the strap that projects below the fixed base 1 may be attached to any suitable device for giving the proper tension to said strap.

In Fig. 6 Ihave shown a metal last secured to the upper end of the post 11 which is employed where nails are to be used in securing the sole or heel to the shoe and in which instance the detachable last rest is dispensed with.

From the foregoing description it will be seen that the jack can be adjusted or turned to any position desired for the convenience of the Workman, one position which is very essential being that shown in dotted lines in Fig. 1, it being a position which is generally employed in trimming the edges of the soles.

Having described my invention, what I claim is-- 1. A shoe repairing jack composed of a fixed base, a movable vertical member secured to the same, an arm hinged to the upper end of `said member and having a base, an adjustable post movably secured to said arm and adapted to carry a last, a continuous passage running through the several parts, and a pulley mounted at the juncture ot the passage of the post and arm respectively, substantially as set forth.

2. A shoe repairing jack composed of a fixed base, a movable member secured to the same, an arm hinged to the upper end ofthe movable member and having a base, a post 11 ad justably secured to said arm and adapted to support a last, a continuous passage running through the several parts, a pulley 4c mounted at the juncture of the passage of the post and arm respectively, and means oarried by said movable member and co-operating with the arm about its pivotal connection for holding said arm in any adj usted position, substantially as set forth.

3. In a shoe repairing jack, a post l1 having a rounded cavity 21, a semi-circular shoulder 22 separated from said cavity by a suitable space 23, and a suitable last rest having a rounded portion 18, a semi-circular resting portion 19, and a neck or connecting portion 20, all respectively co-operating with the similarly shaped portions of the post, substantially as set forth.

4. A shoe repairing jack comprising a fixed base 1, having a socket 2,a movable member 3 having a reduced portion, an annular grooveV 4 formed on said reduced portion, a thumb screw 5 co-operating with said groove, an arm hinged to the upper end of said movable portion, a base forming a part of said arm, a post 11 adj ustably secured to said arm and adapted to support a last, depressions formed curved upper edges of said arm, a spring-actuated pawl carried by the `movable portion the engaging ends of which co-operate with said depressions, passages formed in the several parts and in communication with one another, and a pulley mounted at the juncture of the passages of the post and arm respectively over which a suitable strap is adapted to pass and through said passages, substantially as set forth.

In testimony whereof I affix my signature inthe presence of two witnesses.

THEODORE A. MEITZ.
