SHABPENINZ DEVICE FOR RAZOR-BLADES.

Specification of Letters Patent.

- Patented May 24, 1921.

Application filed May 28, 1919. Serial No. 800,397.

following is a full, clear, and exact description, such as willenable others skilled in the art to which it pertains to make, construct, and use the same, referencebeing had to the accompanying drawings, and to numerals of reference marked thereon, forming a part of'this specification.

The object of my invention is the production of asharpening device for safety razor blades, which shall'be simple and effective in construction, comparatively inexpensive in cost, and rovided with securing means to engage wit corresponding means formed on a stropping device whereby the said sharpening device can be readily and conveniently secured to or removed from the stroppin device, in order that the cutting edge of t e blade may be sharpened without removing the blade from the stropping device. I

With this end in view, my invention con sists in certain novelties of construction and arrangements of parts, as hereinafter set forth and pointed out in the claims.

In the accompanying drawings,

Figure 1 represents, a side elevation of my improved sharpening device.

Fig. 2 represents, a front elevation of the same.

Fig. 3 represents, a rear elevation of the same.

Fig. 4 represents, a side elevation of a razor stropping device, in section, showing my improved sharpening device secured thereto and in operative position, and

Fig. 5 represents, a front elevation of thestropping device, a portion of the handle being broken away.

Similar numerals of reference refer to like parts throughout thespecification and draw- I he razor stropping device illustrated in the accompanying. drawings, (forms the subject matter of atent application, Serial No. 280,982,,filed arch 6, 1919) is provided with receiving means to engage with corresponding recelving means formed on the sharpening device, whereby said device can be readily and conveniently secured to or removed from the stroppin device, in order that the cutting edge of t e blade may be sharpened without removing the blade from the stropper.

The said razor stropping device comprises a frame adapted to slide longitudinally of a strop, said frame comprising a body portion 1 and two opposite end ortions 2-2 parallel each to each. A han le 3 is ivotally connected to the frame for permitting movement of the frame relative to the handle, and a blade holder 4: is rotatively connected to the said side portions of the frame. roller 5 is also connected to said s1de port1ons of the frame, and means are carried by said roller for transmitting rotary movement to said blade holder.

. The body or frame of my improved stroppmg devlce may be stamped from; sheet metal or the llke, and afterward bent into the desired shape .as shown.

The front and rear longitudinal edges 66, of the body or frame are preferably bent upwardly to present bearing or guiding surfaces of the strop.

hese bearing or guiding surfaces 66 are provided with receiving means which as illustrated are alined openings 77 formed near the side portions of the frame to en gage with the receiving means formed on bracket 10 and has secured thereto the gear 17 designed to mesh with a gear 18 secured to the rod 9 and which serves to impart rotary motion to the roller.

The bracket 10 in which said honing or abrading roller is journaled may be stamped from sheet metal or the like and afterward bent into the desired shape as shown.

The lower edge of the bracket is provided with two parallel and outwardly extending tongues 12-12, designed to be received in the alined openings 77, formed in the front and rear longitudinal edges 6-*6, of the body or frame of the stropping device, properly positioning the sharpening device.

is also journaled in one of the arms of the are the side portions of a bracket 14 which may also be stamped from sheet metal or the like and afterward bent into the desired shape as shown.

To the inner surface of said bracket 14 in any desired or convenient manner, preferably by means of the plus 15--15, 1s secured a curved spring 16 extending lengthwise thereof. a v

This spring 16 is preferably made from asingle piece of suitable material bent upon itself as clearly shown and designed to bear upon one side of the razor blade so that the required degree of pressure can be exerted against the blade by pressing the pivoted bracket 14, by means of the operators fingers, toward the roller 8.

To operate my sharpening device, 1t 1s only necessary to insert the integral tongues 12-12 of the bracket 10, intothe almed slots 7-7, in the body portion 1 of the razor stropping frame, thereby pos1t1on1ng the sharpening device, and then causin the curved end of the spring tongue 13 o the bracket 10 to snap over one of the longitudinal edges 6, in order to lock the sharp ening device to the frame of the stropping device.

The pivoted bracket 14 is then in the position indicated in Fig. 4 of the draw-- ungs with the longitudinally arranged sharpening operation.

spring 16 bearing against the razor blade 19.

By pressing against the bracket 1 1 with the spring 16 bearing against the razor blade 19 the desired degree of pressure can be exerted against the blade during the Rotation of the roller by means of the handle will sharpen and polish the edge of the blade.

In order to remove the device from the frame, it only becomes necessary to disengage the spring tongue 13 from the longitudinal edge 6 and causin the tongues 12-12 to become disengaged rom the openings 7--7. v

I am aware that changes may be made in the several arrangements of the various parts, as well as in the details of construc tion thereof, without departing from the scope of my present invention; hence I do not wish to be limited to thearrangements and combinations of parts as herein shown and described, as obviousmodifications will suggest themselves to those skilled in the art.

I claim.

1. A device for sharpening razor blades, comprising a frame made from a single piece of suitable material, the lower portlon of said frame being provided with integral means for securing said device to a frame carr ing a razor blade holder, the upper portion of said frame being provided with integral brackets for supporting a roller, a sharpening roller rotatably mounted in said supporting brackets, a handle journaled in one of the roller supporting brackets, means carried by the handle and roller for transmittin rotary movement to said sharpening ro ler, and means to press a blade in said holder against said roller.

2. A device for sharpening razor blades,

comprising a frame made from a single piece of suitable material, the lower portion of said frame being provided with integral means for securing said device to a frame carrying a razor blade holder, the upper portion of said frame being provided with integral brackets for supporting a roller, a sharpenin roller rotatably mounted in said supporting brackets, a bracket pivotally securedto the outer portions of the roller supporting brackets, a spring secured to and extending lengthwise of said pivoted bracket and located in close proximity to the said roller, and adapted to bear upon the razor blade, a handle, means carried by the handle and roller for transmittin rotary movement to said sharpening rol er.

3. A device for sharpening razor blades, comprising a frame made from a sin le piece of suitable material, the lower portion of said frame being provided with outwardly extending integral tongues for positioning and a centrally arranged integral spring tongue for locking said device to a frame carrying a razor blade holder, the upper portion of said frame being provided with integral brackets for sup orting a roller, a sharpening roller rotatab y mounted in said supporting brackets, a bracket pivotally secured to the outer portions of the roller supporting brackets, a spring secured to and extending lengthwise of said pivoted bracket and located in close proximity to the said roller, and adapted to bear upon the razor blade, a handle, means carried by the handle and roller for transmitting rotary movement to said sharpening roller.
