BOOT OR SHOE JACK.

SPECIFICATION forming part of Letters Patent No. 787,557, dated April 18, 1905.

Application filed June 23, 1904. Serial No. 213,881.

To (all whom it may concern:

Be it known that we, ALBERT BOURGET and FRANK ROBERTS, J12, citizens of the United States, residing at Turners Falls, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Boot or Shoe Jacks, of which the following is a specification, such as will enable those skilled in the art towhich it appertains to make and use the same.

This invention relates to boot and shoe jacks; and the object thereof is to provide an improved device of this class which is simple in construction, comparatively inexpensive, and may be conveniently used in all places where boots and shoes are manufactured or repaired; and with this and other objects in view the invention consists in a boot or shoe jack constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanylock-plate which forms a part of the, opera tive mechanism of the jack; Fig. 4, an edge view of said plate, and Fig. 5 a side view thereof at right angles to that of Fig. 4:.

In the construction of our improved boot or shoe jack we provide a base a, having a central upright standard (f, the top portion ofwhich is segmental in cross-section, and mounted on the standard a is a ball or spherical body Z), having a radial bore or passage 6 in the bottom portion of which the standard a of the base a fits, and the bottom portion of said bore is preferably larger than the top portion thereof, as shown at 6 The ball or body 6 is provided in an upper front quarter thereof with a quadrantal recess 6*, which communicates with the bore 6 and one side wall of which is radially corrugated, as shown at 12 and mounted in the other side of said quadrantal recess is asegmental plate 0, the inner side of which is radially corrugated, as shown at 0 and the plate 0, is provided with pins 0 which fit in corresponding recesses 0* in the side of the quadrantal recess 6* adjacent to whichsaid plate 0 is placed, and mounted on said pins are springs (Z, which force said plate inwardly.

In the upper end portion of the bore 0 in the ball or body 6 is mounted a pivot-pin 6, provided at its lower end with a spherical head 6 and which projects above the ball or body, and said pin is free to swing or turn through the quadrantal recess 6*, the upper end of the enlarged portion I) of the bore 6 forming a socket for the head 6 of the pivot-pin e and the standard a of the base a forming a support for said head 6 of the pivot-pin c.

Mounted on the upper end of the pivot-pin e is a standard j, which is adapted .to turn with said pin and the lower end of which is preferably enlarged to form a head f the bottom surface of which is segmental in form, as shown in cross-section at and the said bottom surface of the head f of the standard f is thus made to fit snugly on the corresponding surface of the ball or body Z), and the standardfis secured to the pin 6 by a screw or other device f We have also shown in Figs. 1 and 2 a last g,'which is adapted to be placed on the upper end of the standard f in the usual manner and to be held thereon by a band it,

provided with a hook it, which is adapted to A be connected with an ear [1. secured to the opposite side of the standard f.

At the front of the standard f is'a strong spring-arm 2', which is passed through keepers j, secured to said standard, and said springarm 6 is provided with holes 71 at the lower end thereof and through any of which may be passed a pin, plug, or similar device 70, adapted to be inserted into a corresponding socket or hole in the standard f, and by means of this construction the arm 2' may be vertically adjusted. The upper end of the arm t' is provided with a shoe or head m, segmental in cross-section and adapted to fit beneath the front portion of the last 9, and said arm 2' aids in holding the last 9 in proper position on the standard f. In the form of construction we have indicated at a a pin which enters the top of the standard f and also enters the last 9, and the last g, as shown, is provided with a rib member g which ranges longitudinally of the top of the foot portion thereof and at the base of which is anose-piece g, which fits in the corresponding recess in the top of the standard 7". The parts a and g are of the usual construction and form no part of this invention, and the last 9 may be connected directly with the upper end of the standard f in any desired manner, the parts of our invention which pertain to the standard and are connected thereto being limited to the band g and the arm i.

WVhen constructed in the manner described, it will be seen that our improved boot or shoe jack comprises in substance a base, a ball mounted thereon and adapted to turn thereon and provided in one quarter with a quad rantal recess, a pivot-pin mounted in said recess and held therein and adapted to turn in a vertical plane through the quadrantal recess, said pin projecting from said recess, and a standard connected with the end of said pin and adapted to turn therewith on said ball and with said ball.

()ur invention is not limited to any particular kind or class of lasts, and any preferred form of last may be employed. By means of the construction herein shown and described it will be apparent that the standard f may be held in a vertical position, as shown in Figs. 1 and 2, or it may be turned into a horizontal position, or it may be held at any desired angle to said vertical and horizontal positions, and in addition to these movements the standard f may also be rotated when in either of the positions specified, and by means thereof the operation of lasting boots or shoes or repairing boots or shoes or of making new boots or shoes may be more conveniently performed than with other apparatus of this class as usually constructed.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A boot or shoe jack, comprising a base, a ball mounted thereon and provided in one quarter with a quadrantal recess, a pivot-pin mounted in said recess and projecting therefrom and adapted to turn therein and in avertical plane and a last-holder secured to the projecting end of said pin, substantially as shown and described.

2. A boot or shoe jack, comprising a base, a ball mounted thereon and provided in one quarter with a quadrantal recess, a pivot-pin mounted in said recess and projecting therefrom and adapted to turn therein and in a vertical plane, and a last-holder secured to the projecting end of said pin, said ball and lastholder being adapted to turn on said base, substantially as shown and described.

3. A boot or shoe jack, comprising a base, a ball mounted thereon and provided in one quarter with a quadrantal recess, a pivot-pin mounted in said recess and projecting therefrom and adapted to turn therein and in a vertical plane, and a last-holder secured to the projecting end of said pin", said ball and lastholder being adapted to turn on said base, and said last-holder being also adapted to turn on said ball, substantially as shown and described.

4, A boot or shoe jack, comprising a base, a ball mounted thereon and provided in one quarter with a quadrantal recess, a pivotpin mounted in said recess and projecting therefrom and adapted to turn therein and in a vertical plane, and a last-holder secured to the projecting end of said pin, said ball and lastholder being adapted to turn on said base and said last-holder being also adapted to turn on said ball, and means forholding the pivot-pin at any desired angle in said quadrantal recess,

substantially as shown and described.

5. A boot or shoe jack, comprising a base, aball mounted thereon and adapted to turn horizontally, said ball being provided in one side thereof with a radially and vertically arranged recess, a pivot-pin mounted in said,

recess and adapted to turn in a vertical plane therein, means for holding said pin at any desired angle in said recess, and a last-holder connected with the end of said. pin which projects from said recess, substantially as shown and described.

6. A boot or shoe jack, comprising a base, a ball mounted thereon and adapted to turn horizontally, said ball being provided in one side thereof with a radially and vertically arranged recess, a pivot-pin mounted in said recess and adapted to turn in a vertical plane therein, means for holding said pin at any desired angle in said recess, and a last-holder connected with the end of said pin which projects from said recess, said last-holder being adapted to turn with said ball and independently thereof, substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of the subscribing witnesses, this 20th day of June, 1904.
