Application filed August 4, 1920. Serial No. 401,144.
To all whom it may concern:
Be it known that I, WILLIAM LUTES a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Electric Edge Heel and Shank Setters; and I do hereby declare the following to be 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 the same.
The present invention relates to improvements in electric edge heel and shank setters for shoes, and has for an object to provide a device of this character which may be applied upon the ordinary shoe machinery either for manufacturing the shoes in the first instance or for repairing the shoes when worn. Another object of the invention resides in providing an improved wheel having portions against which the edge of the sole, heel or shank of the shoe may be placed, arid Within which is provided an improved elec-' tric heating apparatus having connection to an outside sourceof current.
A further object of the invention resides in providing a simple and inexpensive construction of electrically heated edge setter" for setting the edges of soles, shanks and heels of shoes which will be durable in use and may be mounted on existing forms of shoe machin s.
In the acc mpanying drawings forming a part of this application, and in which simi lar reference symbols indicate corresponding parts in the several views: Figure 1 is a. front View showing a portion of a shoe machinery apparatus having the invention applied thereon.
Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1.
Fig. 3 is a longitudinal sectional View through the heating Wheel showing a portion of the shaft of the shoe machine.

units.
Fig. 7 is an enlarged cross sectional view the method of fastening the coil thereto. Fig. 8 is an inner face view of a supporting head through which the current is carried to the collector rings. I
Fig. 9 is a fragmentary plan View of portion of the supporting head with the casing removed; and
Fig. l0 is a cross sectional view taken. on
the line l010 of .Fig. 9, with the casing in place. Referring more particularly to the drawings, 1 designates the shaft of a usual form of shoe machine which, for instance, among a number of other devices, carries an emery wheel 2 and pulley wheel 3. At 4 is represented a portion of the framework of the machine and 5 designates the usual bar pass ing between the various spaced apart frames 4 of the machine.
Over the shaft 1 and at a Suitable point thereon as, for instance, between the emery wheel 2 and the wheel 3, I mount a-wheel 6 designed to be heated and. to rotate with the shaft 1 so that the edge portion of the shoe sole or shank may be applied to any one of the various stepped surfaces 7 with which the periphery of the wheel is formed.
Set screws or other suitablev fastenings 8 serve to pass through the wheel 6 and engage the shaft 1 to compel the wheel to rotate when the shaft is put in motion, as, for instance, by a belt from a suitable source of power engaging the pullev wheel 3. The wheel is preferably made of some metal which will receive heat from the electric coils which are placed within the body of the wheel, and which will readily impart this heat to the shoe. As illustrated more particularly in Fig. 5, recesses 9 and 10 are made through the wheel in order to receive the two resistance coils employed.
The recesses open at both ends of the wheel and are closed by a cap piece 11 which may also be provided with a set screw 12 to hold it in place.
Each resistance coil is preferably built up substantially as indicated in Fig. 6, wherein 13 and 14 represent two separated plates of mica or some suitable insulating material between which are laid the windings 15 of the coil. These windings are preferably of flat wire, and the windings are made by carrying of a detail showing one collector ring and the wire from one side to the other alternately of the mica plates in a looping operation, with the ends of the loops left open.
Binding strips of U formation in cross section are indicated at 16 and 17, and are adapted to embrace the longitudinal edges of the mica plates 13 and 14, suitable cement being applied, if desired, to hold the parts in the relation shown in Fig. 6. The mica fplates are curved laterally for the purpose of tting into the recesses 9 and 10 which are struck from a suitable curvature to conform to the wheel 6 in which they-are made, with the resistance coils so built up that. they slip axially into the recesses and are withdrawable for the purpose of making repairs and substituting new coils for burnt out coils.
Access is had to the recesses by the removal of the cap piece 11. The opposite larger end of the wheel 6 is formed with a lip 18 0verhanging a groove 19 in which may be removably placed a disk of asbestos 20 or other insulating material.
Inner and outer collector rings 21 and 22 of copper or other suitable metal are affixed to the larger face of the wheel as by the screws 23 and 24 entering perforated lugs 25 and 26 which project inwardly from the rings, insulated washers surrounding screws 23-24. By reference to Fig. 3, it will be apparent that the lower recess 10 diverges at a greater angle toward the larger end of the wheel 6 than does the upper recess 9, and I follow this construction in order to bring the ends of the coils respectively opposite the two collector rings so that they may be put in electrical connection therewith.
Tn Fig. 7 I show a preferred form of electrical connector which embodies a post 27 having a slit 28 made therein so that the material to the opposite sides of the slit may be compressed and expanded, as the material is to be of a resilient character.
A set screw 29 passes through the slitted portion and acts to clamp'the bifurcated portion of the post about the terminal 30 of the coil, which terminal is seated in the base of the slit 28, as indicated in this figure. In this figure is also shown a slightly modified form of coil inasmuch as double mica plates are provided, the outer of which are designated at 31 andv 32.
The end of the upper coil 9 is, of course,
connected to the collector ring 21 in the same manner as the lower coil is coupled to the icing 22, as just described in connection with it their forward'ends the terminals 33 and 34 of the two coils are coupled together as indicated in Fig. 5, and an arcuate piece of mica is secured as by the screws 36 or other fastenings to the wheel 6, in order -to conceal this joining of the twoterminals and to insulate the same. The two resistance coils are therefore placed in series and receive current through the collector rings as hereinafter described. A
The collector rings are inclosed by the head 37 carried by an arm 38 which has a divided bearing 39 adapted to fit over the bar 5, as shown in Figs. 1 and 2. The head also fits loosely about the shaft 1 and is pro vided withan opening 40, as shown in Figs. 8 and 10 to permit the two rollers 41 and 42 to project into contact respectively with the collector rings 21 and22.
As shown in Fig. 10 the rollers are carried on arms 43 of a substantially bell. crank form, being pivoted at 44 and having tail pieces 45 to which electric loads 46 and 47 are connected. The arms 45 also form suitable parts to which to connect one end of springs 48; the other ends of the springs are connected to lugs 49 on sleeves 50 which surround the upper rounded end 51 of the supporting arm 38. A ring of insulation 52 is also placed between the arm and the sleeve 2 This sleeve furthermore is provided with an ear 53 which carries the pivot for the bell crank lever 43. Set screws or other fastening means 54 pass through the sleeve 50 and into the rounded end 51 of the 38, in order to secure the sleeves a turning movement. A casing is about the opening 40 at the side away the wheel 6 and is adapted to i working parts. A lining of asbestos 5t may be placed on the interior of the casing, if desired.
In operation the leads 46 and 4'? are connected to a suitable source of current which enters through one of the leads and is fed, for instance, by the inner contact roller 41- to the smaller collector ring 21.
The current thence passes through the upper coil through the leads 33 and 34 to the lower coil, and after traversing the latter it issues through the post 27 to the larger collector ring 22 and passes thence to the companion roller 42 which delivers it to the opposite lead and back to the source of current.
The coils are made of any suitable resistance in order to develop the required heat in the wheel 6 which receives such heat from the coils and is raised to the proper temperature for the setting of edges, heels and shanks of shoes which are applied to the wheel in a well understood manner while the Wheel 6 is being rotated together with the shaft 1.
The springs 48 keep the contact rollers in active engagement with thecollector rings fore I do not wish to be limited to such features except as may be required by the claims.
