ALBION K. WASHBURN, OF BRIDGEWATER, MASSACHUSETTS.

SOLE-LEVELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 596,292, dated December 28, 1897.

Application filed January 30, 1897. Serial No. 621,330. (N0 model.)

To on whom it may concern.-

Be it known that I, ALBIONIK. WASHBURN, of Bridgewater, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Sole-Leveling Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates particularly to an attachment to the jack of a sole-leveling machine; and it consists in combining with the jack a swinging frame holding a toe-guard, said swinging frame being adapted to hold the guard firmly in place during the time that the sole-levelin g work is being done and then to swing away from the toe of the shoe, so as to admit of taking off the shoe and of putting another on. This mechanism is illustrated in the accompanying drawings, in which- Figure 1 is a side view showing the jack of a sole-leveling machine with my toe-guard device attached. Fig. 2 is an end elevation of the same.

In the drawings, A represents the base of the jack, and B a standard, to which the-shank O of an iron last or shoe-support L is held by a clamping-piece C and clamp-screws 0*, as shown. To complete the shoe-support L, an adjustable part L (see Fig. 1) is used. This part is connected to a lever N, which is pivoted at N, and is provided with an adjusting and clamping device of ordinary construction.

The above-mentioned parts need not be more fully described for the reason that they are old and of well-known construction.

The new part relates to the frame for holding the toe-guard R,'and consists of the following-described parts: A plate D, having downwardly-projecting arms D D is pivoted on the pins P P, so that it can tip laterally, as indicated by the dotted lines in Fig. 2. To this plate D an upright arm E is attached by a clamping-piece E, held by the clamp-screw E By this construction the upright arm E is free .to be set 011 any part of the plate D and securely fastened. This adjustment of the upright arm E is required in order to adapt the guard R to act for different-sized shoes. At the top of the upright arm E a guard R is attached. This guard may be of rubber or of any suitable yielding substance that will receive the leveling-roller and not injure it, the position of the guard in relation to the toe of the shoe being such that the roller in passing from the sole of the shoe to the guard, or vice versa, cannot injure the tip end of the toe by crushingit down in leaving or by bruising it in returning.

WVhen the leveling process is not going on and when it is desired to put a shoe onto the last or to remove it, then the lever M is allowed to raise up. This will cause the spring S and rod H to be forced upward, and, acting through the arm II, will swing the plate D and the upright arm E over to the position shown by dotted lines in Fig. 2, leaving the last L free from any obstruction, so that the operator may put on or take off a boot or shoe. The lever M is so balanced and controlled that it always comes to its highest position unless forced down by the operator.

To use my device, the operator simply takes his foot from the lever M. This allows the upright arm E and the guard R to fall back into the position represented by dotted lines in Fig. 2. Now the operator can place the boot or shoe in position on the last L, and having secured it thereon by the aid of the lever N in the usual manner he presses the lever M down. This, acting through the spring S,

rod H, and arm H, will bring the upright arm E and guard R to its normal position, the guard B being about on a level or in the same plane with the sole of the shoe. Now the machine may be started and the work of leveling the sole performed in perfect safety.

I claim- In a sole-leveling machine, a fixed last or shoe-support, a toe-guard support, adjustable on a line parallel to the long axis of the last, a toe-guard attached to said support; a frame tilting in a direction lateral to'the said long axis of the last, independent of the last or shoe-support and adapted to hold the said toe-guard support; and mechanism by which said tilting frame is operated whereby the ALBION K. WASHBURN.
