PUTTEE-SHAPING APPARATUS Specification of Letters Patent.

Patented June 19, 1917.

Application filed February 9, 1917. Serial No. 147,594.

To all whom it may concern:

Be it known that I, KALMAN F. SENTI- VANY, a subject of the King of Hungary, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Puttee- Shaping Apparatus, of which the following is a specification.

This invention relates to an apparatus for shaping puttees or leather leggings.

The object of the invention is to provide a simple apparatus which can be easily manipulated by anyone for setting the leather of puttees or leggings so that such articles will conform to and remain in the shape of the limbs of the persons by whom they are to be worn.

The apparatus which embodies this invention has a forming block of the desired shape and that can be readily heated arranged for the convenient application of the leather from which the article is to be made, and has a sectional mold of a corresponding shape that is arranged so that it may be easily placed upon the leather for pressing it to the forming block and quickly opened to permit the free removal of the leather from the forming block after the leather has been set in the desired shape, the edge outline of the mold being of such a shape that it forms the pattern by means of which the leather can be trimmed to final shape before being removed from between the forming block and the mold, and the mold lining being so made that it will score the leather where it is to be stitched, where the straps are tobe fastened and where the loop slits are to be cut.

Figure 1 of the accompanying drawings shows a side elevation of the apparatus with a small portion broken away. Fig. 2 shows a section on the plane indicated by the dotted line 22 on Fig. 1. Fig. 3 is a view looking at the outside of the flattened mold lining and showing the scoring means.

The apparatus is mounted on a. plpe l which may be supported by any suitable means and connected with any convenient source of steam supply. The forming block 2, desirably of cast iron, is shaped so that it will give the desired conformation to the puttee or legging which it is desired to make.

The block will, of course, vary somewhat in size and shape according to the diflerent sizes and shapes of puttees or leggings to be made and it is loosely mounted on the supporting tube so that it may be moved longi block so'that when the block is slipped onto 7 the angular portion of the tube the apparatus will remain upright, but when the block is slipped longitudinally off from the angular portion of the tube the apparatus is free to be rotated.

The mold, which is desirably formed of iron, has a back section 1, the inside of which conforms to the back of the forming block, that is, that section of the forming block which shapes the back or that part of the puttee which is to conform to the calf 0f the leg of the wearer. Hinged to each side of the back section of the mold are two side sections 5 and projecting from the free edges of these mold sections are lugs 6. The ends of the lugs are slotted and to the slotted end of one a clamp screw 7 is pivoted. On the threaded end of the clamp screw is a clamping nut 8. When the clamping screw held by one lug is swung into the slotted end of the opposite lug the clamp nut may be turned up so as to draw the two lugs together and force the two hinged sections of the mold against the forming bloc-k. When the nut is loosened and the clamp screwturned out of'the slot the hinged sections of the mold will swing out so as to free the mold from the forming block.

The mold is supported by a yoke 9, being held'thereto by the press screw 10 and guiding rods 11. The press screwis threaded through the yoke and its lower end is rotatably held in the boss 12 on top of the back section of the mold. Therpress screw has a handle 13 by means of which'it may be rotated. The lower-ends of the guiding rods are fixed in the boss and the upper ends extend loosely through the yoke. The yoke at one end is hinged by a pivot 11 to an arm 15 which extends outwardly from the forming block. "At the other end'the yoke is adapted to be temporarily fastened by a pin 16 to a lug 17 which projects from the forming block. When the pin is removed the yoke may be swung up so as to lift the whole mold up and away from the forming block. -A lug 18 is desirably provided on the arm 15 to form a stop which will support the yoke and hold the mold in an upright position when it is'swungaway from the forming block. The inside of the mold is preferably lined by a piece of leather 19 which is secured in place by screws 20 and nuts 21.

The yoke is unlocked by withdrawing the fastening pin and the mold swung up". A piece of moistened leather 22 is laid on the forming block and the mold is swung down and the yoke fastened. The back section of the mold is then forced down by turning the press screw so as to press the leather and cause it to closely conform to the back of the forming block. The whole apparatus is then moved bodily lengthwise until it is free from the squared portion of the supporting tube and is turned over until the yoke hangs down. The free edges of the leather to be shaped, which is already clamped by the back portion of the yoke, are brought in against the forming block and the hinged sections of the mold brought together and tightened on the leather by the nut and clamp screw. The apparatus can then be rotated until the yoke is up and moved longitudinally until the forming block is again engaged with the squared portion of the supporting tube. In this condition the apparatus remain-s until the leather has dried and set in the desired shape. The edges of the leather may be trimmed off by means of a knife which is drawn around the end edges of the mold and along the meeting edges of the mold. This gives the leather the finished shape. A strip of wood may be set into the iron block along the meeting edges of the mold section so that the knife used in trimmingthe leather will not be dulled; To remove the leather the clamp screw is u-nfastened so as to release the hinged sections of the mold, and after the fastening pin is withdrawn the yoke and the mold swing up leaving the leather free to be removed. A number of these devices, the same or different sizes and shapes, may be arranged on a bench in a row and by the time all are filled with leather and the molds clamped the one in which the leather was first placed is ready to be opened and the leather removed.

The leather lining 19, which is shown opened out in Fig. 3, has the contour of the finished puttee or legging. In order to mark the leather which is pressed the lining is stitched with heavy threadat various localities in such manner that the thread will form a welt on the inside which will be im-- pressed in the puttee leather and score it when in the mold. This is desirably stitched completely around the edge 2ft to provide a trimming, near the top 25 and near the bottom 26 of one meeting edge to show where the ends of the straps are to be attached, and at 27 and 28 to indicate where the leather is to be slitted to form the loops through which the binding straps are passed. By this simple means every puttee shaped in the apparatus is marked so that it may be quickly and neatly finished.
