Specification of Letters Patent.

Patented May 6, 1913.

To all whom t may concern.'

Be it known that we, ARTHUR BATES and ERNEST A. CRIDLAND, subjects of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in VVork-Supports, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

rThis invent-ion relates to improvements in or relating to machines for reforming turn shoes or for leveling the bottoms of boots or shoes.

More particularly the invention is applicable to machines for reforming turn shoes of the type described in an application for United States Letters Patent Serial No. 492,489 filed Apr. 27, 1909.

The object of the present invention is to provide a device for holding the shoe firmly on the jack or for both holding it and molding the waist of the shoe.

A feature of the invention, which is applicable to machines for reforming turn shoes or for leveling the bottoms of boots or shoes, comprises means for holding the shoe firmly on the jack or for both holding it and molding the waist of the shoe comprising a stirrup the shoe bottom and hold it there under pressure while the shoe bottom is being operated upon.

As another feature of the invention the strap holding means is arranged so that it will yield whereby the stirrup or strap is held yieldingly or resiliently in contact with the shoe bottom and preferably means is also provided for varying the pressure applied by the yielding means.

These and other features of the invention, including novel details of construction and important combinations of parts, will appear more fully from the following description when read in connection with the accompanying drawing and will be pointed out in the appended claims.

In the accompanying drawing,-Figure l is a front elevation of a machine embodying the present invention; and Fig. 2 is a side elevation, partly in section, of. the machine shown in Fig. l.

or stra-p and mechanism operatively connected thereto which is adapted to forcel the said stirrup or strap into contact with Referring to the accompanying drawing the machine comprises an upright frame or support2 at the head of which is mounted a rack bar 4. Mounted on the rack bar 4 is a toe pad 6 for supporting the toe and at its other end a last pin 8 for supporting the. heel end of a last upon which is carried the shoe to be operated upon. The toe support 6 and the heel support 8 are mounted so that they can be adjusted toward and from each other by means of

hand wheels

10, 12.

A leather stirrup or strap 14 is adapted to embrace and bear on the waist of the shoe as shown in Fig. 2 and is attached in any convenicnt manner, for example by hinged connections having longitudinally extending

pintles

16, 18, and

transverse pivots

17, 19, to a fork or yoke 20, having

arms

22, 24. The said strap is preferably attached to the fork so that it is readily detachable. The

arms

22, 24 are situated one on either side of the rack bar 4 at points adjacent to the heel support as shown and the said fork or yoke 20 is provided at its lower end or bightwith a hollow boss 26 through which passes a tubular post 28 having a head 30 which is adapted to rest on the boss 26.

When the strap 14 is released from pressure against the shoe it may be raised from contact therewith by a spring 66 and may then be swung backwardly over the heel of a shoe on the support and relatively to the yoke about the

transverse pivots

17, 19, the yoke and post remaining in a posit-ion of substantially stable equilibrium over the pivot 48 about which further movementof the strap may be had if desired. By reason of the pivotal connection of the yoke 2O with l the post 28 the strap is adapted to be turned around by the yoke for use upon right and left shoes without removal from the yoke which carries it. This construction enables a non-symmetrically-shaped strap to be used which has one end thickened so as to fit the unequally inclined sides of the unsymmetrical shanks of right or left sho-es, for, as is well-known, the shanks of shoes, particularly ladies shoes, are unequally inclined at the opposite sides, the greater lateral inclination of the shank being upon the inner side. Inside the said tubular post 28 is situated a rod 32 having a block 34 secured thereto by means of a` knurled headed set screw 36. A spring 38 is provided which surrounds the said rod and contacts at one of its ends with the block 34 and at its other end with a plug 40. The plug 40 is iiXed in the interior of the post 28 at its lower end by means of a clamp 42 which surrounds the lower end of the post 28 and is provided with a screw 44 so arranged that when the screw is turned it will act to contract the lower end of the post to hold the plug in place, a slot 46 being provided in t-he post to permit such contraction. The rod 32 is thus yieldingly supported in the post 28.

Thelower end of the rod 32 is pivoted at 48 to a treadle 50 fulcrumed at 52 to the frame 2 of the machine and it will be understood that when the treadle is depressed the strap 14 will be pulled downwardly against the shank of the shoe through the rod 32, spring 38 and the parts just described. A handle 54 is provided for raising the block 34 and connected parts. The handle 54 has a shoulder and a reduced threaded portion which is screwed into the block, the Vshoulder preventing contact of the threaded po-rtion with the rod 32. Slots are provided in the post 28 for the handle 54 and the set screw 36. The pull on the work is determined by the tension of the said spring 38. In order to vary the tension of this spring the set screw 36 `is unscrewed and the block 34 raised or lowered by means of the handle 54. When the required adjustment is obtained the screw 36 is again set up tight.

In order to hold the treadle 50 in its lowermost position and consequently maintain the pressure on the shank of the shoe while the work is operated on, a pedal 56 is provided which is pivoted to the treadle 50 at 58 and is acted upon by a spring 60 one end of i which is attached to the pedal 56 and the other to the treadle 50 so that when the treadle 50 is in its lowermost position (see Fig. 2) the pedal 56 will engage, by means of a face 62, a catch 64 fixed to the frame 2 of the machine. It will be understood that when the pedal 56 is depressed the face 62 will be released from the catch 64 and the treadlel 50 will then return to its inoperative position under the action of the spring 66. The face 62 and catch 64 are lheld in place by screws so that a new. face and catch can be substituted therefor if they become worn.

The screw 36 prevents rotative movement between the post 28 and the rod 32 and when the treadle 50 is in its highest position it will bear against the top of the slot 53 and lift the post 28 bodily upward so that the said strap is clear of the work and can he swung` away therefrom to enable the shoe to be lifted from 01T the jack, the said vspring supported rod 32 swinging about its pivot48 on-the pedal 50. The boss 26 beside being loose on the post 28 may be arranged for longitudinal movement thereon so that the post will slide through the boss without raising the yoke when the treadle is raised by the spring 66. The strap may in this case be lifted off t-he shoe by hand and hung upon the projection of the ack.
