P. H. DIXON MACHINE FOR CUTTING SHOE TREEING STICKS Filed Feb. 1, 1938 Patented Jan. 23, 1940 UNITED STATES PATENT OFFICE MACHINE FOR CUTTING SHOE TREEING STICKS Paul H. Dixon, Swampscott, Mass, assignor to United Shoe Machinery Corporation, Borough of Flemington, N. J., a corporation of New Jersey Application February 1, 1938, Serial No. 188,112

2 Claims.

placed between these members, thereby being placed under tension and as a result will prevent the sole of the shoe from turning up. In order that the stick may function efficiently as a shoe tree it must be properly proportioned to the -lengths vary with different styles and sizes the sticks must be individually cut for the shoe in which they are to be used.

It is an object of this invention to provide a machine for cutting shoe treeing sticks which, in combination with the shoe to be treed, will enable the operator to determine readily the proper length of stick for that particular shoe and to cut the stick to that length forthwith. To this end, and as illustrated, the machine provides a frame having a knife slidably mounted therein and means thereon for engaging a shoe when presented to the machine and holding the rear. portion thereof a determined distance from the knife whereby the latter may sever the projecting portion of a treeing stick at a fixed distance from the counter.

These and other features of the invention will appear more fully in the following detailed description when read in connection with the accompanying drawing and will be pointed out in the appended claims.

Fig. 1 is a front view of the machine embodying this invention; and

Fig. 2 is a sectional view taken along line II-II of Fig. 1 and illustrates a shoe in operative position relatively to the knife.

The illustrated machine comprises a. frame Ill having a rectangular recess formed in the head thereof in which is slidably mounted a plunger l2. Attached to the front face of the head is a guide plate l4 having a cutting blocks 5 fastened to the inner face thereof, the cuttingblock being received in a channel l8 formed in the upper portion of the plunger I2. The top of the cutting block has formed thereon a knife 20 which is arranged to cooperate with a knife 22 attached to the plunger l2 at one side by an v extension 24 formed on the plunger. The knife 22 is open at one side so that long reeds or sticks may be inserted sideways from the open side.

The adjoining surfaces of the knives 2D and 22 are made convex and concave respectively in order that the severed face of the treeing stick which is to engage the counter will be rounded so as not to damage the shoe.

The upper portion of the front face of the guide plate M has a heel seat 25 formed therein for engagement with the rear portion of a shoe and thus to hold the heel spaced from the knives, as shown in Fig. 2, thereby controlling the point at which the stick will be severed. The slidable.

blade 22 is moved downwardly by a rod 26 fastened at one end to the plunger l2 and con-' nected at its opposite end to a treadle-lever 28 pivotally mounted on a base 30. The plunger [2 and blade 22 are biased in an upward direction by a spring 32 surrounding the rod 26 and held between a plate35 which engages a table 34 and a collar 36-fastened to the rod 26.

The treeing sticks are out each to an appropriate length in the following manner. A stick such as 38 is first inserted in a shoe so that one end Will engage the tip thereof, as shown in Fig. 2, with the opposite end portion extending outwardly over the edge of the counter portion of the shoe. Then the shoe is presented to the machine heel first, so that the heel will be received in the seat 25. When in this position the projecting portion of the resilient stick 38 will lie between the knife blades where it may be severed by the operation of the treadle-lever 28.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

.1. A machine for cutting shoe treeing sticks comprising a'fixed knife, a work locating member extending along one side of the knife and having a curved seat adapted to engage and position the counter portion of a shoe in spaced relation to the edge of the knife, and a movable knife on the other side of the fixed knife and cooperable therewith to sever the treeing stick at a predetermined distance beyond the counter portion of the shoe.

2. A machine for cutting shoe treeing sticks comprising a fixed knife and a movable knife having curved cutting edge portions cooperable to sever a treeing stick projecting from a counter portion of a shoe presented to the machine, and a work locating member adjacent to the knives :and having a curved seat constructed and arranged to engage the counter portion of the shoe to position it in predetermined spaced relation to the cutting edge portions of the knives.
