ATTACHMENT FOR EDGE-SETTIN G MACHINES.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed November 14, 1914. Serial No. 872,070.

To all whom it may concern Be it known that I, RAOUL J. B. MON- CHAMP, a subject of the King of Great Britain, residing at Manchester, New Hampshire, United States of America, have invented certain new and useful Improvements in Attachments for Edge-Setting Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

The invention to be hereinafter described relates to an attachment for edge setting machines. v

In order to more clearly disclose the construction, operation, and use of the inven- I tion, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings like reference characters designate the same parts.

In the drawings: Figure 1 is a front View of the device, partly broken away to show its interior construction; and Fig. 2 is an underneath View partly broken away.

The main objects of the invention are, to provide a neat, compact, durable, and efficient device for use in connection with edge setting machines, in the manufacture of shoes and footwear, for burnishing purposes.

Referring to the drawings in detail, 1 designates a steel head of circular cross section, the upper portion of which is of frustoconical shape. A heavy shank 2 is made integral with the head and is threaded at its upper end, for attaching purposes. The under face of head 1 is centrally recessed to receive superposed heating coils 8. An opening is provided through the center of the coils, and a screw 4 is inserted through this opening and threaded into a suitable bore in a plug 5 centrally located above the heating coils. The coils 3, screw 4, andplug 5, are all effectually insulated from each other and from head 1, by thick layers of asbestos cement, or other suitable insulating material. To prevent heating of the coils, they are each halved by a bridge 6 of asbestos cement. Several layers of mica are placed between the heating coils and the removable bottom plate 7, so as to prevent heating thereof. A sleeve 8, of material of high electrical conductivity, is mounted about the upper portion of screw 4, and effectually insulated therefrom by an asbestos sleeve 9. This sleeve is also insulated, at its upper end, from bottom plate 7 by a thick mica washer 10, and at its lower end, from the head 11 of the screw 4, by a similar washer 12. Sleeve 8 and screw head 11 are each grooved, near their lower ends, to receive collared connecting members 13 and 14, respectively. These members are snugly, but not tightly, mounted and are detachably connected, by wires 15, to opposite sides of a suitable electrical circuit. One end of the coils 3 is connected to sleeve 8 by means of a wire 16 passed through, the insulation between the coils and plate 7 plate 7, and washer 10, and secured to sleeve 8. The other end of the coils is connected to plug 5, which is of a high electrical conductivity, by wire 17 which passes through bridge 6 and the insulation about the plug, and is secured thereto. I

When wires 15 are properly connected, the electrical current will enter coils 3 by screw 4 and plug 5 and leave by sleeve 8, or vice versa. The flow of the electrical current through coils 3 will soon render them very hot, which will raise the lower portion of head 1 to a high temperature. The head 1 is provided, with two diametrically opposite, integral, and angularly disposed pins 18, which project beyond its under face. These pins are adapted to fit snugly into the tubular shanks 19 of properly shaped burnishing irons 20, the head being properly recessed about the pins to snugly receive the shanks. By this means, very intimate contact is established between the irons and the head 1. To secure the irons in position, a fiat steel arm 21 is provided. This arm has lateral tabs 22 which straddle each side of head 1 and are pivotally connected thereto by screws 28. The upper end of the arm is forced outwardly by a pressure coil spring 22*, which has its inner end seated in a suitable bore in the head and its outer end fitted over a pin integral with the arm. The lower end of the arm is turned inwardly to form a short cylinder 23 which fits tightly into a semicylindrical groove 24 adjacent the upper outer edge of the head of the iron 20, when the iron is in operative position. By this means, the iron is securely retained in operative position, but may be quickly and easily mounted, or demounted, as required. As the head 1 heats the heat is transmitted to irons 20, by pins 18, which are quickly raised to the proper temperature for use.

Due to the fact that connecting members 13 and 14: are not tightly mounted about sleeve 8 and screw 4, this device may be revolved, as desired, without in any way interfering with its connections or operation, as will be clear from Fig. l of the drawings. In use, this device may be attached, by

means of shank 2, to the ordinary edge settin machine, in place of the setting tool,

and then may be used in the ordinary It is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition of the several parts of-the invention without in any way departing from the field and scope of the same, and it is meant to include all such within this application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a device of the character described; a head, having its under face recessed; attaching means integral therewith; heating coils mounted in the recess of the head and insulated therefrom; means for electrically connecting the said coils to an electrical circuit, such means being arranged to permit revolution of the head; irons carried by the head and detachably mounted therein; and means for securing the irons in operative position.

Copies ofthis patent may be obtained for '2. In a device of the character described; a head having its under face recessed; integral attaching means therefor; heating coils mounted in the recess of the said head and insulated therefrom and from each other; a plug of material of high electrical conductivity centrally located above the coils and electrically connected to one side thereof, and insulated therefrom and from the head, and having a centrally screw threaded bore; a plate removably secured on the lower faceof thesaid'head; a screw inserted through the plate and the coils and threaded into the said plug, the said screw being insulated from the said coils and plate and having an annularly grooved head; an .annularly grooved sleeve of high electrical conductivity mounted about the -:upper portion thereof and insulated therefrom and from the said plate and electrically connected to the other side of the said coils; means for connecting the said sleeve and screw to opposite sides of an electrical circuit, so as to permit revolution of the said sleeve; diametrically-opposite angularly disposed pins integral with the said head and (projecting beyond the lower face thereof; ironsvadapted to be mounted on the said pins; and means for holdingthe irons in po- 8 s'ition, such means being carried :by the said head.

In witness whereof I have hereunto set my hand in the presence of two witnesses. RAOULJ. B. ,MONGHAMP. Witnesses:
