UNITED STATES I OLE PETERSON, or CLEVELAND, oHIo.

SEOE-GEMENTING- PRESS.

Application filed February 27, 1928. Serial lfTo. 257,335.

My invention relates to shoe presses, or

clamping devices for cementing full soles,

half soles, or soles with French heels, to a boot or shoe. In general my object is to provide a universal shoe-press adapted to permit different kinds of repairs to be made on various types and kinds of shoes without alteration or change or substitution of parts in and to the press, and to provide a simple and sturdy device which may be easily manipulated and facilitate the operations of cementing full soles or half soles on shoes of different size and form. A further object of my invention is to provide a shoe supporting member slidably arranged for horizontal adjustment with" respect to a device for pressing the shoe downwardly upon said supporting member. Furthermore, according to my invention a yielding support is provided for a shoe, the suporting surface being flexible and self-adaptable to the form or shape of any bottom or sole portion of a shoe. i

In the accompanying drawing, Fig. 1 is a vertical section centrally of the shoe, and

Fig. 2 a side view thereof; Fig. 3 is a perspective View of one of the shoe supporting members; Fig. 4 is a perspective view of the frame and working parts of the shoe 30. supporting member without the tubular rubber pad, and Fig. 5 is a perspective view of the pad itself. Fig. 6 is an enlarged perspective view of a portion of the pad.

The present device facilitates sole cementing operations on either new work or a repair job, but it is especially useful in repairing shoes as it permits quick and accurate repairs to be made in shoes of all sizes and shapes. In practice, the worn sole of a shoe S to be repaired is first removed; then a suitable cement is applied to the exposed bottom of the shoe and to a new sole. The shoe and new sole are then jointly seated upon a flexible pad or cushion P, and pressure applied to the top of the shoe through a wooden 0r metal shoe-last L previously inserted within the shoe. In general, such pressure applying devices are old and well known, and called shoe cementing presses. The present device is designed for universal repair work, including shoes in which the sole or part of the sole extends flownwardly over the breast portion of the eel.

The press comprises a base plate 2 having a yoke-shaped frame 3 extending across its middle from end to end. The top portion 4 of frame 3 is provided with vertical openings and guides 5 for a pair of toothed racks or lun ers 6-6 each 0f which is -6 p z: a

adapted to be raised and lowered by a small gear or pinion 7 .and a crank or handle 8. A locking pawl 9 is pivotally mounted upon the cross part 4 adjacent each gear or pinion. Each plunger is provided with a presser foot 10 extending -rearwardly at a right angle and thence downwardly and forwardly at an inclination, to provide an inclined foot part 10 having dependant projection 10 to engage the inclined top face 11 of a shoe last L at two separated places during pressing operations when a shoe is sleeved upon the last and seated upon the yielding pad P. The pad is secured to an open skeleton frame 12 having legs 13 to permit it to be seated upon base plate 2 and shifted into any desired Working position beneath the presser foot 10. Thus the shoe may be placed with a separate sole upon pad P and with thebreast of the heel abutting the thickened and rounded end 1 1- of the pad. lVhen the pad and its frame is properly situated on base 2 with respect to presser foot 10 a uniform pressure may be applied over the face of the sole, and the downward movement of the shoe also applies pressure to the breast at the juncture of the heel and the shoe bottom.

In Figs. 1 to ,6, I show an irregularly curved pad P made of flat tubular rubber stock, the end portions 15 of which are folded inwardly to provide rounded end edges and increased thicknesses of rubber at opposite ends of the pad, thus making such end portions more strongly resistant to stretch or less elastic than the main or middle portion of the pad, and thereby also producing a fold line or buckling shoulder inwardly of the end about at the point Where the inner end edge of a half sole terminates when placed on a shoe bottom. The pad being tubularalso permits it to be sleeved over a pair of stretching and holding elements, comprising two round-rods 1616 having downwardly bent end portions 17-l7 which may be inserted ,within suitable openings in the top part of one end of frame 12. The tension rods may be detached from the frame but when connected thereto are free to swing in a horizontal plane, either toward or away from each other. Thus when the tension rods are moved or turned approximately parallel the free ends thereof are ada ted to engage curved projections or 1100 is 18-18 at opposite sides of frame 12. Accordingly pad P may be attached in a fixed position and stretched tightly over the open top of frame 12 by sleeving the rubber tube over the two rods and then spreading the rods apart until the free ends are interlocked with hooks 18-18, the rubber stretching in the operation and the inherent tension in the rubber serving to lock the rods and pad in a simple and effective way to frame 12. The opposite end of the pad is also stretched over the rods but may be fasprojected therethrough.

tened additionally to frame 12 by an angular clamping bar 19 and screws or bolts 20. Such additional locking anchors the pad the full width of that end of the pad, and pre vents creeping or displacement. The bottom wall of the tube where inturned at its ends is slit or perforated at 21 near each corner of the pad sothat the hooks 18-18 and the bent ends 17 of the tension rods 16 may be 7 The rods are also curved downwardly for a greater part of their length, and the rubber tube or pad is stretched to a correspondingcurvature to provide a curved seating surface for the shoe, while the'arched middle portion of the shoe and the heel breast is accommodated and placed under pressure by the stiffer four ply end portion of the pad. The degree of clamping pressure on the shoe and pad is controlled by the presser foot and its operating rack and gear, see Figs. 1 and 2.

lVhat I claim, is:

1. A shoe cementing press, comprising a U-shaped frame having a flat base, a presser foot having rack and gear means supported upon said frame, and an open frame movably mounted upon said base beneath said presser foot and having a yielding seating pad for a shoe.

2. A shoe cementing press, comprising'a base member having a yoke-shaped frame extending across the same, a rectangular open frame seated for free movement horizontally upon said base member, an elastic pad carried upon said rectangular frame and adapted to seat a shoe and a sole for the shoe, and a presser member movable vertically upon said frame, including a rack and gear for raising and lowering said presser member.

3. A shoe cementing press, comprising a base member having a frame bridging the same, a vertically movable presser element supported by said frame, and means for raising and lowering said presser element, said element having a bent offset of V-shaped form terminating in a slanting extremity and said extremity having a depending projection at its rear portion to permit the support of said presser element, on two sepa rated places of the slanting surface of a shoe last.

4. In a shoe cementing press, vertically movable shoe clamping means, and a shoe supporting member having an elastic pad, one end of which is projected beyond the rear edge of said member to also engage the breast of the heel of a shoe.

5. In a shoe cementing press, a frame having a pair of rods pivotally secured thereto, and a tubular pad detachably connected to and stretched between said rods.

6. In a shoe cementing press, a pair of hinged elements, and an elastic tubular shoe seating member sleeved over and stretched by said hinged elements.

7. In a shoe cementing press, an open frame, a-pair of rods pivotally connected to said frame, a rubber tube sleeved upon said rods, and means on said frame for locking the rods thereto when spread apart and the tube is under stretch and tension.

8. A shoe cementing press, including a rectangular frame, a rubber tube, and means on said frame for supporting and stretching said tube to form a curved surface across the top of said frame.

9. A shoe cementing press, including a frame, a rubber tube folded at one end, and means hinged to said frame for securing said tube upon said frame, said means being adapted to stretch the folded end of said tube when placed in proper working position.

1.0. A shoe cementing press, including a frame having projections, tension elements pivotally secured to said frame and engageable with said projections, and a tubular pad of elastic material sleeved upon said tension elements.

In testimony whereof I afiix my signature.
