SHOE-FINISHING JACK.

SPECIFICATION forming part of Letters Patent No. 317,091, dated May 5, 1885.

. Application filed March 5, 1885. (No model.)

To all whom it may concern:

Be it known that I, JONATHAN FRANK CHILD, of Marlborough, in the county of Middlesex and Commonwealth of Massachusetts,

have invented certain new and useful Improvements in Shoe-Finishing Jacks and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,form- 1-0 ing a part of this specification, in which- Figure 1 represents a top or plan view of a shoe-finishing jack embracing my said improvements, the drawings being one-half full size. Fig. 2 represents a side view of the parts shown in Fig. 1, looking in the direction of arrow 1 and Fig. 3 represents a central vertical section on line A B, Fig. 1, looking in the direction of arrow 1.

To enable those skilled in the art to which my invention belongs to make and use the san1ne,I will proceed to describe it more in detai The object of my present invention is to produce a shoe-finishing jack adapted for use upon any'work that is required to be done on ashoe after the last is taken out or removed from it, and which improved jack, with but slight and simple adjustments, can be used with all sizes of shoes, from and including childrens shoes to and including mens large brogans.

In the drawings, the part marked 0 represents a section of the bench having an opening, 0, cut out to receive the duplicate coils a a of spring D, operating treadle cord or chain E, and guide-stem or projection Eof the adjustable jack-stand F, the latter being held upon the jack-base G by means of lugs G, which are fastened to its under side and project under the inwardly-projecting flange b of the base G, which latter is securely fastened to the top of the bench C. With this arrangement the jack-stand F can be turned round and afterward fixed in any desired position by means of the lug c on the end of thumb-screw d, as fully indicated in Figs. 2 and 3 of the drawings. From the upper side of the jack-stand F rises a projection, F, the upper end of which is cored or bored out to 5 receive the stem H of .the standard H of the ,E in any suitable manner.

last part I, the part I being cored out on its under side, as seen at I, with an opening, e, in the rear part, as fully indicated in Figs. 2 and 3 of the drawings.

Upon the rear end of the adjustable jack- Stand F are cast or otherwise secured two flanged guidepieces, f f, between which is held the sliding heel part J ,"said part J being provided with projecting flanges to slide underneath the flange parts of the guide-pieces f, as fully indicated in dotted lines, Fig. 1,

and full lines, Fig. 3.

In the upper inner face of the heel part J is formed a slot, in which is hinged or pivoted the heel end of the shank-supporting piece J.

A double spring, B, is secured between the front stationary part, II, and the adjustable part J, as follows: The loop part h of said spring rests or bears against the inner face of the movable part J, a pin, h, passing through the loop into the adjustable part J, while the ends of the double spring are bent and entered into holes formed in the inner side of the stationary projection F. By this arrange ment an open space is left between the loop of spring D and the arms 9 thereof, and through this opening the chain or treadlecord E passes, the upper end being fastened in any convenient and proper jmanner to the adjustable jack part J, and then passing between the loop and ends 9 of spring D over'a pulley, E, pivoted in a slot formed in the lower part of the upwardly-projecting piece F, thence down through the guide-piece E and opening 0, and connected to a foot-treadle, K, said tradle being arranged and secured to the lower end of the operating cord orchain In the drawings the operating-cord is shown secured to the treadle in the same manner as theupper end by means of a screw, while it has a swivellink, L, for the purpose of permitting the jack to be turned on the base-piece G into any de-.

sired position without twisting or cramping the operating cord and treadle.

Instead of the treadle-cord being fastened, as indicated in the drawings, it may be drawn through and bent up against the'treadle and a screw passed through it or fastened in any other convenient manner.

To prevent the heel part of the jack from slipping out, a stop-screw, M, is secured tothe adjustable jack-stand F, and the base of the heel part J is slotted out to allow it to slide out, as indicated in full lines, Fig. 1. The part which supports the front of a shoe and which is made in the form of a last can be removed with its standard H and stem H, and another (smaller or larger) last part I substituted therefor, thus enabling this part of the jack to be adjusted quickly for supporting the front part of different sizes of shoes.

The heel part N of the jack part J is also made so that it can readily be removed and a larger or smaller piece substituted for the purpose of supporting the heels of different-sized shoes. This is accomplished by cutting away a portion of the upper rear part of J and applyingapieee, N, having apin, N, which passes down into a hole in the upper end of jack part J. For instance, if it is desired to apply a heel part which proj eets farther back, the one shown in full lines, Fig. 3, is removed and another inserted in its place extending back, as indicated in dotted lines, same figure.

If desired, a spring-plate and pin may be applied to one side of the projection F for holding the stem H from being pulled out while the jack is in use. This spring-plate can be easily sprung back, thereby withdrawing its pin from the holes in the part F and stem H, thereby permitting the stem to be withdrawn and another with a different-sized last part I inserted in lieu thereof.

From the base-piece G projects an arm, 0, to which is pivoted the piece P, which in turn is secured in any proper manner to the top of the bench, and by which arrangement the jack can be swung over to one side for the purpose of finishing the edge of the shoe, and as the jack-stand F can be turned round the shoe can be turned, so that without changing the position of the piece I each edge of the shoe can be alternately turned up and exposed to the view of the operator for finishing, thus rendering the device very convenient in this respect, and, if preferred, in any case the part 1? can be quickly removed from the bench and fastened to it in any other position less than an entire revolution of the base-piece G.

In Fig. 1 of the drawings is shown in dotted lines one position in which the parts F, I, J, and N may be turned when necessary for convenience in finishing a shoe.

The parts shown in full lines in the drawings represent such an arrangement of parts as will enable the jack to be used in finishing shoes of the sizes six to eleven, inclusive, and by taking off the last part I and substituting one corresponding to the front part of the last for a boys shoe, the device will be adapted to finishing numbers one to five, including womens shoes, and by substituting a youths size last part I, the device can be used on all childrens shoes. Then, again, by substituting in lieu of the part N,a heel part of the size indi cated by dotted lines in Figs.:2 and 8, the device as thus shown in the drawings is adapted for use in finishing sizes eleven to thirteen, inclusive, Inens brogans.

One great advantage of my present improvethe heel part N, when the part J is allowed to move back by the action of spring D, thereby causing the shoe to be held in an easy and perfect manner during the operation of finishing, the action being so easy and perfect as not to remove or injure the crimping of the shoe, but to leave it just as perfect in this respect as when it comes off the last.

My jack is also adapted for use in performing all light stamping required to be done on a shoe, and that, too, without any fear of breaking it.

The operator in removing a shoe from the jack has only to place his foot upon the treadle K and give a slight pressure, when the jack part J will be drawn forward, as indicated in dotted lines, Fig. 3, thereby relieving the part N from pressure against the heel part of the shoe, which can then be readily slipped off and another placed thereon, after which, the foot being removed from the treadle, spring D causes the movable part J to move back into its normal position, thereby holding the shoe in an easy but secure position for finishing.

Owing to the manner of holding the base of part J under the flange-pieces f f of the flanged pieces f f, the friction is such that the force exerted upon the upper part of the jackpiece J in finishing the shoe is not sufficient to move the part J out of position. Vhen the movable part J of the jack is moved forward, the point an of the hinged shank supporting piece J will run up on the inclined face a of the part H, and, passing through the opening a, will run into the openingin the last part I.

Those skilled in the art to which my invention belongs will readily understand and appreciate the great practical advantages due to its use.

Having described myimprovements in shoefinishing jacks, what I claim therein as new and of my invention, and desire to secureby Letters Patent, is

1. The combination, with base F, for supporting the jack, of the base-piece G, provided with flange b, lugs G, thumb screw d, and lug c, substantially as and for the purpose set forth.
