ABRASIVE AND HOLDER THEREFOR Filed March 5, 1952 i 4/ I c/wezflw N MW 4? @zzm Qfmw a 73, 9M 9M Patented May 16, 1933 UNITED STATES WILLIAM Gr. DUNN, F CLARINDA, IOWA ABRASIVE AND HOLDER THEREFOR Application filed March 5,
An object of my invention is to provide an abrasive and a holder therefor which are particularly adapted for sharpening and stropping safety razor blades and which are, from a manufacturing standpoint,comparatively simple and durable as well as inexpensive.
A further object is to provide an abrasive and a holder, opposite edges of the abrasive being pivotally, connected with supporting members of the holder, the supportingmembers being closer together than the distance between said edges of the abrasive so that the abrasive must assume a curved position when held in the holder, thus making it adaptable for safety razor blade honing and sharpening.
Still a further object is to form the abrasive of relatively thin stiff flexible material so that it will retain its curved position when held in the holder, the edges of the abrasive being pivotally connected with the holder so that such curvature can be reversed without removing the abrasive from the holder.
Still a further objectis to provide an advertis-ing novelty including an abrasive sheet of material with advertising printing printed on the abrasive surfaces thereof.
Another obj ect is to provide a holder having a pair of spaced supporting members and one or more forms of rigid connecting memhere between the supporting members.
Still a further object is to form the holder of relatively rigid material such as'iron wire, but which may nevertheless be manually reformed so as to vary the spacing between the supporting members of the holder and thereby vary the curvature of the abrasive so as to adapt the device to fit different widths of safety razor blades or those having diflerent bevels on their sharpened edges.
With these and other objects in view my invention consists in the construction, arrange ment and combination of the various parts of 5 device, whereby the objects contemplated are attained, as hereinafter more fully set forth,'pointed out in my claims, and illustrated in the accompanying drawing, in which:
Figure 1 is a perspective view of an abra- 1932. Serial No. 597,080.
sive and holder therefor embodying my invention. I
Figure 2 is a side elevation of the same showing it in use. I
Figure 3 is a perspective view fied form of holder.
Figure 4 is a perspective view of still another modified form of holder; and
Figure 5 is a bottom plan view of Figure 4.
On the accompanying drawing, I have used the reference character A to indicate a holder and B an abrasive. The holder A hasv a connecting member 10 terminating in sup-' portingmembers 12.. The holder A as disclosed, may be made of heavy wire and the portion 10 thereof is preferably curvedas shown. 7
The abrasive Bis a sheet of fiber or other suitable material, thesurface 14 of which is of a modiadapted for stropping'a razor. The reverse surface (16) is coated with abrasive material so that the surface 16 may be used for honing a safety razor blade.
The eye members 18 receive the supporting members 12 of the holder A and the supporting members are spaced closer together than the initial distance between the eye members-that is, whenthe abrasive sheet B is flat. This causes the abrasive sheet to assume a curved position. l
The abrasive sheet B is of comparatively thinflexible material having sutficient stifiness to retain it in its curved position even though slight pressure may .be applied against it.
In Figure 3, I have shown a modified form of holder A for theabrasive. It has parts 10a and 12a corresponding to the parts 10 and 12 of the holder A. The difierence of construction lies in the connecting. portion 10a which instead of curving directly from one supporting member 12a to the other one, curves also across the face 16 of the abrasive sheet B. In side elevation, however, the appearance would be substantially as shown in Figure 2.
In Figures 4 and 5, I have shown a modified form in which the holder A comprises a pair of members with supporting ends 12?) and connecting portions 105 which curve toward each other and may be secured together by a clip 24. In side elevation, this holder would also be substantially similar to F igure 2.
An abrasive sheet of this character lends itself readilyasan advertising novelty and accordingly advertising printing 26 may be directly applied thereto, as shown in Figuret.
The printing is inked on the abrasive surfaces and does not afi'ect the honing and stropping characteristics of the sheet.
In Figure 2, I have shown the abrasive and holder in use. The abrasive B is reversed in this figure relative to its position in Figures 1 and 4 and the same as its position in Figure 3. The abrasive is formed of comparatively thin stiff flexible material so that force can be applied thereto to buckle it from the curvature of Figure 1 to the reverse curvature of Figure 2, the members 18 pivoting on the members 12. The users hand is indicated at 28 and the holder is held between the heel 32 of the hand and the fingers'34" as illustrated. A safety razor blade 35' I ative to the abrasive sheet.
As shown by dotted lines in Figure 2,-the radius of curvature'of the connecting memberlOof the holder A may be reduced, or the holder may be otherwise manually reformed to space the supporting members 12 closer together and thus reduce the radius of curvature of the abrasive sheet B. Inversely, the spacing between the members 12 can be increased for increasing the radius of curvature of the sheet B where the character of the blade requires it Some changes may be made in the construction and arrangement of the abrasive sheet and the holder with respect to each other without departing from the real spirit and purpose of my invention. It is therefore my intention to cover by my claims, suchmodified forms of structure or use of mechanical equivalents which-may be reasonably included within their scope.
the normal distance between said opposite edges whereby said abrasive assumes a curved position, the space between said supporting members being unobstructed whereby said abrasive may be reversed without removal from said holder and means for rigidly connecting said supporting members together.
2. An abrasive and a holder comprising a pair of spaced supporting members coacting with opposite edges of said abrasive to support it and means for rigidly connecting said supporting members together, said supporting members being closer together than the distance between said edges of said abrasive whereby the abrasiveassumes a curved position and said means being clear of the abra sive to permit its reversal without removal from the supporting'members.
3. An abrasive and a holder comprising a pair of spaced pintles pivotally coacting with opposite edges of said abrasive to support it and means for rigidly connecting said pintles together, said means being manually bendable to vary the space between said pintles. a
4. An abrasive and a holder comprising a pair of spaced pintles pivotally coacting with opposite edges of said abrasive to support it, means for rigidly connecting said supporting members together, said pintles being closer together than the distance between said edges of said abrasive whereby the abrasive assumes a curved position and said means being manually bendable to vary the space between said pintles.
I 5. An abrasive comprising a sheet of material and a holder therefor connected with opposite edges of said abrasive, said abrasive being curved when so connected with said holder and being formed of stifi flexible material whereby-to retain its curvature and its whereby the curvature may be reversed without removal of said sheet from said holder. 7
6. An abrasive comprising a sheet of material and a holder therefor connected with opposite edges of said abrasive, said abrasive being curved when so connected with said holder and being formed of stifi flexible material whereby to retain its curvature,-said connections each beingof pivotal character whereby the curvature of the abrasive may be reversed without removing the abrasive from the holder.
7. An abrasive of flexible sheet material having fine and coarse grain surfaces and a holder therefor, opposite edges of said abrasive sheet coacting with said holder and the I abrasive sheet being supported thereby in curved position, each coaction being pivotal and the holder being so formed whereby said curvature can be reversed while the abrasive sheet remains in the holder without said holder interfering with such reversal;
8. An abrasive comprising a sheet of abrasive material and a holder therefor comprising supporting members coacting with opposite end edges of said sheet for holding the sheet in curved position and means rigidly connecting said supporting members together, said means being curved to position adjacent the plane of curvature of said abrasive sheet and arranged along one side edge thereof.
