Oct. 27, 1931. J. B. RHODES SHARPENING DEVICE FOR RAZOR BLADES Filed Feb. 4. 1929 Patented Oct. 27, 1931 JAYnnHoDEs, or xALAMAzoo, MICHIGAN SHRPENING (DEVICE FOIR RAZOR BLADES Application-filed February 4, 1929. Serial No. 337,327.

The main objects of this invention are:

First, to provide a sharpening device for razor blades andthe like which is highly eiicient and atthe same time capableof easyv manipulation.

Second, to provide a sharpening device in which the blade is held in proper relation to various kinds of sharpening elements, that u is, -flexible straps such as razor straps or sharpening elements presenting non-flexible surfaces.

Third, to provide a sharpening device having these advantages which is very simple and economical in its parts and at the same time strong and durable in use. l

Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The `invention is defined in the claims.

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawings, in which:

F ig. 1 is a plan view of my improved sharp- A ening device in operative relation to a strap, 25v

portions being broken away to show structural details.

Fig. 2 is an inverted viewy of the device with the handle partially broken away.

Fig. 3 is a side view of the device in operative relation to a strap and illust-rating the position of the parts when a stroke is being made toward the left.

eccentrically relative to the axis of the roller or are substantially spaced from the axis of the roller. On these pivots I mount a carrier 7, stop shoulders 8 being provided on the roller for limiting the swinging movement of the carrier.

The carrier is provided with a holder for a blade such as 9, which consists of a cross member f 10 and a blade clamping member 1] which is slidably mounted on the carrier and provided with keepers 12 engaging with lugs 13 on the carrier. The member 10 is provided with studs 14 while the clamping member 11 is longitudinally slotted at 15 to receive these lugs'. The lugs are adapted to engage the openin gs commonly found in certain vtypes of safety .razor blades.

With the parts thus arranged the Carrier and roller are supported for limited relative pivoted and swingingmovement." The roller` has a recess or flattened portion 16 between the pivots and adapted to provide blade engaging shoulders 17. These shoulders swing downwardly upon the edge of the blade as indicated in Fig. 4 and hold it in engagement with the strap.

In use the device is pressed upon the sharp-y ening element f and reciprocated back and forth thereon. Assuming that it is laid upon the strap or other sharpening element with the carrier in advance of the roller or in the direction of the first stroke, the initial movement will cause the roller to swing up to the firmly and in proper relation to the strap. On reversing the stroke the carrier is swung vover they roller and the parts assume the opposite position,that is, the carrier is Vswung into a position in advance of the roller and i vpositionshown in Fig.- 4 holding the blade l My improved sharpening device is economical in its parts, is very convenient to use and is highly eiiicient. I have not attempted to illustrate or describe certain modifications or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.

Having thus described my invention what I claini as new and desire to secure by Letters Patent is:

l. Ina sharpening device, the combination with a handle, of a roller rotatably mounted on said handle and provided with radially projecting ears and having a recess in its periphery between said ears, and a blade carrier pivotally mounted on said ears, said roller beingfprovided with stops limiting the swinging movement of said blade carrier, sain car ier being adapted to support a blade with the edge thereof to be sharpened adja cent the roller and positioned to be engaged by one edge of said recess.

2. In a sharpening device, the combination with a handle, of va roller rotatably mounted on said handle, and a blade ca rier pivotally mounted on said roller, the axis of the carrier being radially spaced relative to the axis of the roller, spaced stops on said roller coasting with said carrier, said roller being pro vided with a flattened portion between the pivots of the carrier, said carrier being adapted to support a blade with its edge to be sharpened in position to be engagedby the flattened portion 0I" the roller.

3. In a sharpening device, the combination with a handle, of a roller rotatably mounted on said handle, and a blade carrier pivotally mounted on said roller, the axis ot the carrier iicing radially spaced from the axis of the holder, the carrier being provided with a blade holder adapted to support a blade with its edge to be sharpened adJacent the roller, the roller having peripherally .spaced blade engaging shoulders.

In a sharpening device, the combination with a holder, of a roller rotatably mounted on said handle and provided with radially pro'ecting ears and peripherally flattened be-V l with a handle, of a roller rotatably mounted I on aid holder, and a blade carrier pivotally .pivots oi' the carrier, said carrier being adapted to support a blade with its edge to be sharpened in position to be engaged by the liattened portion of the roller to be dellected and supported thereby against a sharpening element.

6. In a sharpening device, the combination with a handle, a roller rotatably mounted on said handle, and a blade carrier pivotally mounted on said roller, the axis of the carrier being spaced radially from the axis of the roller, stops limiting the relative movement of the roller and carrier, the carrier being adapted to support a blade with its edge to be sharpened adjacent the roller .and the roller having spaced blade engaging parts.

In witness whereof I have hereunto set my hand. y

JAY B. RHODES.
