JOSEPH FLEET, OF HARRISBURG, PENNSYLVANIA, ASSIGNOR 'lO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEWV JERSEY, A CORPORATION OF NEW JERSEY.

WORK-SUPPORT.

Specification of Letters Patent.

Patented Sept. 19, 1916.

To all whom it may concern Be it known that I, JOSEPH FLEET, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain Improvements in Work-Supports, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indlcating like parts 1n the several figures.

This invention relates to shoe machines, and particularly to a work support which may be found of especial use in connection withbed lasting machines.

In lasting shoes upon machines of the bed type, such, for example, as that shown in United States Letters Patent to Brock, No. 1,018,477, the toe portion of a shoe rests upon a pad against which it is held more or less securely by the jacking mechanism and preferably also by a hold-clown, and the wipers are closed in against the side of the toe portion and are moved upwardly to bring the upper into close contact with the last, to remove wrinkles therefrom, and after applying substantial tension thereto to wipe the upper over the feather of the insole and hold it in place during the application of the toe wire. In performing this operation, however, some difficulty has been experienced, especially when making shoes on lasts having high toes, because of the tendency of the upper to bridge across the low part of the last between the toe and the instep. Another difliculty consists in distortion or bowing of the tip line due to the tension applied to the toe of the upper while insuflicient pressure was applied over the tip line to hold the upper firmly against the wood of the last.

It is accordingly an object of the present invention to provide, in connection with means for supporting the toe, means for preventing the bridging of the upper by holding the upper against the wood of the last and also for keeping the tip line straight by pressure exerted along the tip line.

An important feature of the invention consists in means for applying pressure 10- cally to the box of the toe, preferably along the line, or lines, where the box is sewed to the upper, commonly known as the tip seam. This localized pressure is preferably applied resiliently through a rather stiff spring, and

preferably means is provided for equalizing the pressure upon the different portions of the tlp seam to which pressure is applied.

It 1s also a feature of the invention that the means for applying pressure locally to the tip seam is combined with means which may be relatively movable and of usual construction for supporting the toe of the shoe. As embodied herein a toe rest of usual construction is provided and in the rear of the toe rest is located an additional narrow pad WlllCh is adapted to engage the shoe along the tip seam and is so mounted in its sup port that it may tip about an axis extending longitudinally of the shoe and substantially in the plane of the sole to accommodate itself to variations in the relative thickness of the two sides of the last. The pad carrymg member may be supported on suitable plungers, as shown, and may be forced upwardly to engage the shoe by a suitable spring.

These and other features of the invention, including novel arrangements and combinations of parts, will appear more fully from the following detailed description, when read with reference to the accompanying drawings and from the appended claims.

Figure 1 is a perspective view of a toe rest embodying the invention; and Fig. 2 is a side elevation partly in longitudinal section of a machine provided with a toe rest embodying the present invention.

In the drawings, Fig. 2, the reference character A indicates the toe head of a lasting machine upon which the mechanism for carrying and operating the wipers B is located. The toe head A is provided with a rearward projection 2 having a vertical hole in which the toe post 4: is mounted for longitudinal movement, a screw 6 being arranged to enter a groove in the post 4 to prevent rotation of the post. Upon the upper end of the post a is a block 8 on which the toe pad 10 is mounted by a block 12 having the usual transverse slide 14 and longitudinal slide 16. At the rear of the pad 10 is mounted a rocking clamp comprising a pad 20 and a box 22. The pad is preferably of rubber, and of such extent longitudinally as to engage the shoe locally in the region of the tip seam. The pad 20 is preferably crescent-shaped and is mounted in the box 22 which is segment-shaped and is seated in a segment-shaped cavity in 1104 a block 24:, the latter being mounted for vertical movement on plungers 26 which extend through the sleeves 28 rigidly mounted in the block 8. Between the plunge'rs 28 is a third plunger 30 which passes freely through a hole in the block 8 and upon which is a spring 32 acting to elevate the pad 20. Limiting stops are provided by pins 33 passing through the lower ends of the plungers 26 and engaging the lower face of the block 8. To retainthe pad 20 and boX 22 in position in the block 2% a pin 34 is provided which passes through the pad 20 and box 22 and rests in slots 36 formed in the sides of the block 24 and curved from the center of movement of the box 22.

In operation the shoe is jacked in the usual way, the post 4 being raised to press the pads 10 and 20 with considerable force against the shoe which is held in position, not only by the usual heel lasting mechanism but preferably also by a hold-clown 0. During this jacking operation the pad 20, being normally located above the pad 10 (as shown in Fig. 1) engages the shoe first and presses the upper .at the tip seam firmly against the last before the pad 10 engages the shoe, and aids the pad 20 in holding the upper in position. The pressure of the pad 20 locally at the tip line continues during the lasting operation and prevents the central portion of the tip seam from being drawn forward by the tension applied to the upper in the lasting operation resulting in a bowed tip seam which is unsightly and otherwise objectionable.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A work support comprising a vertically rigid toe rest, a yielding presser located at the rear of the rest, normally projecting above said rest and adapted to contact with the shoe along the tip seam, and means for equalizing the pressure applied by said yielding presser to the tip seam.

2. A work support comprising a crescentshaped member which is mounted for lateral rocking movement, is restrained from horizontal movement and is adapted to contact with the toe locally along the tip seam to clamp the upper of the shoe against the last and to prevent movement of the upper longitudinally of the last during the lasting of the toe.

3. A work rest comprising a rigid support for the toe of a shoe and laterally rocking supplemental means for conforming to the surface of the last and applying equalized pressure to clamp the upper to the last along the tip seam..

4. A work support comprising a pad for sustaining the toe portion of the shoe and means movable about an axis extending longitudinally of the last arranged to act upon the shoe prior to its contact with the pad to force the upper against the last and prevent bridging of the upper between the instep and toe when operating upon shoes with high toes.

5. A Work support comprising a pad for sustaining the toe portion of the shoe, and means arranged to contact with the shoe prior to its contact with the pad and to exert a pressure along the horizontally disposed portion of the tip seam to force the upper closely against the last along its thinnest portion, said means being mounted for movement about an axis extending lengthwise of the last and lying substantially in the plane of the sole.

6. A work support comprising vertically rigid means for sustaining the shoe, a clamp mounted for rocking movement and arranged to clamp the upper against the last at the tip seam, and means independent of the rocking movement for yieldingly supporting the clamp.

7 A work support comprising a toe rest and a tip seam clamp located toward the heel of the shoe from the rest, resilient means for upholding the clamp, and a structure in addition to said means whereby the clamp is mounted to rock transversely of the shoe to adapt its position to the shape and position of the last at the tip seam.

8. A work support comprising a two-part toe rest, one part being vertically rigid but constructed to permit movement thereof by the shoe in a plane parallel to the last bottom and the other part being restrained from movement in said plane and mounted to slide vertically.

9. The combination with a base 8 and a toe pad 10, of a pad 20, a plunger 30 passing through the base and secured to the pad 20, a spring 32 on the plunger and adapted to sustain the pad 20, guides 26 and stops 33 on the ends of the guides 26 for limiting the movement of the plunger 30.

10. A work support, having in combination, a toe rest 10 having horizontal slides 12, 16 at right angles to each other, and a tip line rest 20 resiliently mounted on a spring 32 and having guides 26 to permit movement of the tip line rest in a vertical direction only.

11. In a lasting machine, a toe rest comprising a vertically movable stem having a head, a toe support unyieldingly mounted on the head, a tip seam clamp mounted on the head in the rear of the toe support to have a bodily yielding movement downwardly and means normally holding said clamp at a higher elevation than the toe support.

12. In a lasting machine, a toe rest comprising a vertically movable stem having a head, a toe support unyieldingly mounted on the head and a clamp also mounted on along the tip seam to clamp the upper of the shoe against the last and cooperate with 15 the toe rest in, preventing movement of the upper longitudinally of the last during the lasting of the toe.

In testimony whereof I have signed my name to this specification in the presence 20 of two subscribing witnesses.
