HEEL SANDING ATTACHMENT Filed Sept. 13, 1954 Giuseppe Mas/ran drea I N V EN TOR.
Y B M km nited States Patent HEEL SANDING ATTACHMENT Giuseppe Mastrandrea, Bluefield, W. Va. Application September 13, 1954, Serial No. 455,709 4 Claims. (Cl. 51-190) This invention relates to a heel sanding attachment and more specifically provides a device for attachment to a shoe machine for sanding heels on shoes and especially adapted for work on heels requiring sanding of areas that are hard to reach with the usual sanding attachment.
An object of this invention is to provide a heel sanding attachment for shoe machines that includes an improved and novel construction wherein the abrasive member utilized for sanding the heels will last a relatively long time, thereby increasing the efliciency of the sanding operation and decreasing the cost incidental to the replacement of the sanding member.
Another object of the present invention is to provide a heel sanding attachment that is easily and quickly attached to the shoe machine and one that is easily and quickly disassembled for replacement of the abrasive member. s
A still further object of the present invention is to provide a heel sanding attachment having a frusto-conical element thereon for receiving the abrasive member wherein the frusto-conical element is provided with a concaved outer surface, thereby permitting the sanding of all types of heels as the outer edge of the frusto-conical member presents a thin edge.
Yet another important object of the present invention is to provide a heel sanding attachment for shoe machines that is simple in construction, eflicient in operation, easy to attach, easy to assemble and disassemble for replacement of the abrasive member, provided with a long lasting abrasive member, well adapted for its intended purposes and relatively inexpensive to manufacture and maintain.
These, together with other objects and advantages which will become subsequently apparent, reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is a side elevational view of the heel sanding attachment of the present invention;
Figure 2 is a longitudinal, vertical sectional View taken substantially upon a plane passing along section line 2-2 of Figure 1 showing the details of construction of the heel sanding attachment of the present invention; and
Figure 3 is an exploded group perspective view showing the various component parts of the heel sanding attachment of the present invention and showing the manner in which they are interfitted and interrelated to each other when they are assembled onto the driving shaft of the shoe machine.
Referring now specifically to the drawings, it will be seen that the numeral generally designates the heel sanding attachment of the present invention for detachable engagement with the driving shaft 12 of any conventional shoe machine wherein the drive shaft 12 is telescopically received within the heel sanding attachment 10 and the drive shaft 12 is also provided with a flattened portion 14 at the end thereof for receiving and expediting the attachment of the heel sanding attachment 10.
The heel sanding attachment 10 includes a generally tubular elongated sleeve 16 having an externally threaded end portion 18 at one end thereof and a peripheral flange 20 at the other end thereof wherein the peripheral flange 20 is provided with a screw threaded opening 22 for threadably receiving a setscrew 24 which engages the flattened portion 14 of the drive shaft 12, thereby securely positioning the heel sanding attachment 10 on the drive shaft 12 for rotation therewith.
Positioned around the outer surface of the tubular sleeve 16 and engaging the inner shoulder of the peripheral flange 20 is a tubular collar 26 having a countersunk outer end portion 28 and a peripheral rib 30 at one end thereof, wherein the peripheral rib end 30 engages the inner shoulder of the flange 20 on the tubular member 16, and the countersunk end portion 28 of the collar 26 is provided with outwardly tapering side walls for a purpose described hereinafter.
Threadably engaged with the threaded end 18 of the tubular sleeve 16 is an internally threaded cap 32 having oppositely disposed, laterally projecting ears 34 on the closed end thereof, and the closed end of the cap 32, as indicated by the numeral 36, is generally concave for a purpose described hereinafter. A frusto-conical member 38 having a centrally located bore 40 is positioned over the tubular sleeve 16 with the cap nut 32 received in the bore 40 and engaging the threaded end 18 of the sleeve 16. The outer end or large end of the frustoconical member 38 is generally concave, as indicated by the numeral 42, and the concaved surface thereof is provided with a pair of diametrically opposed recesses 44 that are similar in shape to the laterally projecting cars 34 on the cap 32. It will be noted in Figure 2 that the thickness of the ears 34 is less than the depth of the recesses 44, thereby recessing the concaved closed end 36 of the cap 32 in relation to the concaved end 42 of the frusto-conical member 38, thereby assuring that the cap 32 will not engage the material being sanded by the heel sanding attachment 10. A frusto-conical, tubular, abrasive member 46 is positioned on the outer surface of the frusto-conical member 38 and the abrasive member 46 is substantially the same size as the outer surface of the frusto-conical member 38 and closely engages the entire surface as it is constructed of a single integral tubular member.
In assembly, it will be noted that the small or inner end of the frusto-conical member 38 and the tubular abrasive member 46 are received within the countersunk end 28 of the collar 26, thereby assuring that the abrasive member 46 will be forced outwardly into close association and engagement with the outer surface of the frusto-conical member 38. The particular positioning of the ears 34 and the recesses 44 prevent relative rotation between the frusto-conical member 38 and the tubular sleeve 16.
The frusto-conical member 38, as well as the collar 26, may be constructed of material such as hard rubber or plastics that will withstand the pressure exerted thereon but still will not mar the surfaces being sanded in the event of accidental engagement therewith. The abrasive member 46 may be of a type well known to the industry. However, it is constructed of a single thickness of abrasive material, thereby eliminating any overlap or seam wherein the abrasive member 46 will have long wearing qualities and the number of heels that may be sanded before changing of the abrasive member will be greatly increased. Obviously, if desirable, the tubular sleeve 16 and the collar 26 may be constructed integrally of the same material and the entire device may be quickly disassembled by holding the tubular sleeve 16 and rotating assert-r4 thecap nut 32anitheimstmconical-memben38,-thereby backing the cap nut 32.0ff of the threaded end 18 of the tubular sleeve 16.
T -tvrom the foregoing; :tIre'cGnStr'uctiOn-and eparation of the "device will be =-readily"understood;=-and-**further explanation is believed to be'unnecessaryi However,
