Be it known that I, PEARL J. WENT- wonrr a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Shoe-Shaping Machines, of which the following description, in connection with the accompanying draw ings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the manufacture of boots and shoes and particularly to machines for use in the shaping of turn shoes to conform the shoe accurately to the shape of the last and to give it a smooth and finished appearance,

An object of the invention is to effect improvements in the construction of machines of this general class, and to this end a feature of the invention resides in means which may be suitably positioned to treat a shoe presented thereto at one side of the machine, with provision for bodily movement of the shoe treating means laterally at the convenience of the operator from its location for use to an idle position upon the machine. One form of such means may comprise, as shown, a tool arranged to beat the Work by rapid impulses, together with an operating device, such as a suitably rotated cam, for imparting tothe tool its shoe beating movements and into and out of operative relation to Which the tool is mounted to swing. a i

A. further feature of the invention conin the combination of shoe beating means and shoe ironing means movable alternatively'into operative position for treating a shoe presented at one side of the machine. As herein shown the machine includes upper beating and ironing tools that are in some respects similar in construction and relative arrangement to those disclosed in United States Letters Patent No. 87 6,249, granted to S. J. Wentworth, Jan. 7, 1908, with provision for lateral movement of the spindle which carries the beating tool and is encircled by the ironing tool, so as to bring either of said tools into suitable relation to the operator as he stands in front of the machine. With this arrangement it is not necessary for the operator to change his position materially in presenting the rod in both directions.

embodies means to enable him to bring the different tools to position quickly without material effort or waste of time.

A further feature of the invention resides in thecombination of a beating tool and an ironing tool movable alternatively into position to treat a shoe and means for maintaining said tools in heated condition. Either tool is thus maintained in readiness for instant use whenever required. In the preferred arrangement, which includes a reciprocatory spindle that is encircled by the ironing too], the heater comprises an electrical heating unit located at that portion of the spindle which is within the ironing tool.

These and other features of the invention, including certain details of construction and combinations of parts, will now be described with reference to the accompanying drawings and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a machine embodying the preferred form of the invention, Fig. :2 is an enlarged perspective view of the upper portion of the machine, with certain portions broken away for clearness, Fig. 3 is vertical section through the machine head and the shoe treating tools, Fig. 4- is a fragmentary plan view illustrating the operation of the beating tool upon a shoe.

Upon the frame 2 of the machine is formed a boss 4 which provides a bearing for a vertical spindle 6. Secured to the spindle at its upper end by means of a pin 8 is a tool carrying head 10 which is thus rotatable with the spindle and rests upon the upper end of the boss 4-. The head is bored horizontally to receive a reciprocatory rod or spindle 12 which carries at its outer end a beating tool 141. A key 16 enters a flat keyway 18 in the rod 12 and serves to prevent rotation of the rod and to limit the reciprocato-ry movement of the The rod 12 is held normally at its forward limit of movement by a spring 20, and in operation is moved backwardly by the pressure of a shoe against the beating tool 14, with the upper presented to the tool in the relation shown in Fig. 4., until the rear end of the rod projects into the path of a rotary cam 22 which will thus impart to the rod and beater a rapid awe:

succession of forward shoe beating movements as long as the shoe is pressed against the beater. The cam '22 is carried by a belt driven shaft mounted in a bearing carried by a standard 23 on the frame.

Secured to one side of the head 10 is a bar 24 which is bored to receive one end of a rod 26 and has a. spring 28 in the bore to force the rod out vardly. The rod 26 is provided with a bracket 30 which carries a roller The arrangement is such that this roller is below the heater and projects somewhat forwardly therefrom. Rotation of the rod 26 is prevented by a rod 34 carried by the bracket 30- and projecting operation to that disclosed in United States Letters Patent No. 844,293, granted to S. J.

' Wentworth, Feb. 12, 1907.

Encircling the spindle 12, somewhat in themanner disclosed'in United States PatentNo. 87 6,249, previously referred to, is an ironing tool 36 which. is mounted rotatably on a bearing 38 on the head and has a. flange 40 which. is held against the end of this bearing by one end of the spring 20. In

. the ironing operation the shoe ismoved in the lever.

rolling contact with the periphery of the tool 36 which is rotated on its bearing through contact with the shoe.

It will be readily seen that for the beating operation the spindle 12 should project forwardly toward the operator, while for the ironing operation the tool 36 should project laterally in front of the operator to bring its peripheral surface into proper position to receive the shoe. To effect such change of position of the tools the arrangement provides for rotation of the head 10 back and forth through substantially ninety degrees. The spindle 6 projectsdownwardly through a bearing 42 formed in a bracket 44 on the frame and has at its lower end a crank arm 46 with axpin 48 that engages in a slot 50 for'me'din a lever 52 which is pivoted at 54 to the bracket 44. At its forward end the lever carries a member 56 to be engaged by the operators leg for swinging With .the parts arranged as shown it will be clear that a comparatively small movement of the lever will serve to rotate the head 10 sufiiciently to bring the parts may be returned to their first position to beat a shoe. For retaining the head 10 in either position of adjustment the boss 4 is provided with two depressions 5S substantially ninety degrees apart. and the head 10 has a projection 60 which is bored to receive a spring held plunger (52 the end of which is rounded to enter said depressions so as to oppose but not prevent rotation of the head. As an additional safeguard to prevent rotation of the head when the shoe is pressed against the ironing tool, the boss 4 is provided with a projection 64 with which the projection 60 on the head engages When the parts are in the dotted line position. This arrangement effectively prevents further swinging movement of the ironing tool away from the operator.

It is necessary to provide heating means for the ironing tool, and for the best results also it is desirable that the tool 14 be heated to some degree. The machine includes an arrangement whereby both tools may be heated effectively from the same heating device. As shown in Fig. 3, an electrical heating element 66, supplied with current by wires 68, is located within the spindle 12 at such a point as to be encircled by the tool 36. The heater will thus serve to heat the ironing tool to the required degree, and at the same time is sufliciently close to the tool 14 to impart to this tool also a substantial degree of heat. The wires 68 extend, as shown, through a bore in the spindle 12 and out at one side of the spindle and through a notch 7 0 in the head 2 so as not to interfere with the reciprocation of the spindle in beating a shoe. With this arrangement both tools are maintained in heated condition ready for instant use.

In using the machine, the workman stands in front thereof with one leg in engagement with the member 56. With the parts in the position shown in the drawings the spindle 12 is in operative relation to the cam 22 so as to be engaged by the cam when the spindle is moved endwise by pressure of a shoe against the tool 14. The cam will thus impart a rapid succession of shoe beating movements to the tool. When it is desired to iron the upper the operator swings the lever 52 a short distance and thereby turns the head 10 so that the tools assume the position represented by dotted lines, the plungcr 62 slipping out of the forward depression 58 and into the rearward depression and the projection 64 effectively preventing further rotation of the head in this direction. The ironing tool is now in position to treat the shoe in the well known manner.

When it is desired to resume the beating operation the parts may be returned instantly to their first position by a reverse movement of the lever 52.

Although the machine has been described as especially intended for operating upon turn shoes, it will be obvious that it may be used to treat any shoe that may be subjected advantageously to upper beating and ironing operations. It will be understood also that although the invention has been dis closed as embodied in a machine having the specific features of construction shown and described, the invention is not thus limited in its application, and that other embodiments are comprehended within the spirit and scope thereof as defined by the claims.
