CHARLES I1- WHITE, OF MEDINA, NEW YORK.

ELECTRIC HEATER FOR SHOE MACHINERY.

Application filed. January 24, 1921.

T 0 all whom it may concern Be it known that I, CHARLES L. l/VHITE, a citizen of the United States, and a resident of Medina, in the county of Orleans and State of New York, have invented certain new and useful Improvements in an Electric Heater for Shoe Machinery, of which the following is a specification.

The invention relates to improvements in heating devices for use in connection with certain of the working elements of shoe machinery, and more particularly to an electrically heated element adapted to be asso ciated with the edge setting element of such machinery.

In shoe machinery repair outfits and the like, it is common practice to associate with certain of the working elements thereof, a heating means generally of the gas burner type, and, in the use of which, often results in serious injury to the operators thereof by their hands being burned by reason of having to manipulate the shoe on such working element in the immediate proximity to the heating means.

The primary object of the invention is therefore, to provide a heating means of the character mentioned, and one so associated with the working element of a machine as to be positioned at one side of the latter removed from the working position of the operator, and, consequently, at a point different from that now occupied by known heating devices.

Another object of the invention is to provide for a heating means which may or may not be permanently associated with certain working elements of a machine of the type mentioned, and which may, when permanently associated therewith, be moved away from the working element so as to vary the degree of temperature of the latter if desired, and also may be readily and quickly rendered active or inactive as necessary during the operation of the particular working element with which it is associated.

,With the foregoing and other objects in view, the invention resides in the certain new andusefularrangement and construction of parts as will be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawing, in which Figii'rel is'anend portion of a driven Serial No. 439,416.

shaft of a shoe machine showing the preferred embodiment of the invention associated with an edge setter tool thereon.

Fig. 2 is a transverse section through the driven shaft showing one end of the heating device in elevation, and,

Fig. 3 is a view similar to Fig. 2 wherein is shown the opposite end of the device in elevation.

Referring to the drawing, in Fig. 1 thereof is shown the outer end portion of a driven shaft 10 which projects outwardly of a bearing 11 and carries at its free end an edge setting tool 12, all of conventional form and arrangement.

Slidably mounted ,on the shaft 10 and free from rotation therewith is a heating collar 13, which is circular throughout a greater portion of its facial edge and formed to provide a squared end portion 14 at one side of the circular edge, which portion 14 has a longitudinally extending bore into which is fitted an electrical heating coil 15, the latter being preferably reinovably held in the bore so as to be readily withdrawn for repair or replacement as desired or necessary, and the same is connected to a suitable source of current supply (not shown) by the compound lead 16, extending rearwardly therefrom.

The heating collar 13 is connected by means of oppositely, disposed metal strips or bars 17 to a slidable bearing 18, the strips or bars 17 being suitably soldered or welded at or cast with the opposite sides of the collars 13 and 18 in a plane parallel to each other and to the shaft 10, and are of a length to hold the collars spaced apart one from the other, whereby the collar 18 is not subjected to any appreciable heating effect from the collar 13. The collar 18 is provided with a radially extending interiorly threaded nipple 19 in which is threaded an actuating handle 20.

The total length of the device is substantially less than the distance between the opposed faces of the bearing 11 and the tool 12, so that the heating collar 13 may be moved away from the tool a sufficient distance to allow sufficient room for the operator to take the latter off of the end of the shaft for the substitution thereon of another, or similar tool of the same size. or of a difi'erent size, without burning his hand in the operation. w

For holding the device in its normal position, as shown in Fig. 1, to prevent the re tation of the same with the shaft 10, the outer face of the bearing collar 18 is formed with an angular recess 21, one wall of which, as at 22, is disposed in the plane of the horizontal axis of the same, while the wall 23 is disposed at an angle thereto and is adapted to function as a cam surface. if desired, and into this recess is projected, a pin 2-1, which is carried in the adjacent face of the bearing 11.and lies in a plane parallel to the shaft. This pin 2-4-1: of a length to remain engaged in the recess 2i at all. times, and if the collar 18 is given a quarter turn in its movement to bring the heating collar 13 in abutting relation with the opposite face of the tool 12, the wall 23 of the recess 21 is engaged by the head of the pin and the device is forced outward from the bearing 11 and the heating collar 13 held as firmly desired against the tool 12. However, the device may he slid away from the bearing 11 without the quarter turn movement aforesaid. but in any case the same will be permanently held against complete rotation with the shaft.

It is to be understood that various changes in the detail construction and arrangement of the parts of the device may be resorted to without departing from the spirit and scope of the invention.
