To all whom it may concern:
Be it known that I, Herman Herder, a citizen of the United States, residing at Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Razor-Stropping Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to razor-stropping devices, and has for its object the provision of means in a suitable device whereby the blade of a razor may be suitably supported on the strap while being honed, and whereby the cutting edge on each side alternately is automatically presented to the strap only when the device is moved in a direction away from the edge of the blade, and, finally, whereby the blade edge is automatically presented to the strap in a longitudinally-inclined direction in imitation of the manual movement of a razor-blade on a strap, so as thereby to present the whole blade edge to the strap at each stroke.
To these ends my invention consists in the rotatable blade-holding device hereinafter described, having gearing mounted upon its end, in combination with a pivotally-mounted handle, with means to limit the pivotal swing thereof, and a toothed gearing upon its swinging end meshing with the gearing on the rotatable blade-holding spindle.
In the accompanying drawings, illustrating my invention,
Similar letters of reference in the several views refer to like parts.
The device consists of a holder (indicated at
The device has pivotally mounted upon the extension end
The operation of the device is as follows: The arms
I am aware that various razor-stropping devices have been devised to automatically throw the blade over by its back edge, (but none for inclined honing,) the nearest of which to mine for the first-named purpose being that shown in Patent No. 405,961, dated June 25, 1889; but that device requires that the arms
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is—
1. In a razor-stropping device, the combination with a frame carrying a pair of supporting-arms, adapted to rest upon a razor-strap, of a rotatable blade-holder centrally mounted, in said frame and provided with peripheral cog-gearing and an extension end or spindle journaled in said frame, a handle pivotally connected with said supporting-frame and carrying a sector end provided with rack-gearing meshing with the annular gearing on the rotatable blade-holder, and with means to limit the arc of rotation relatively, of the supporting-frame and the pivotally-connected handle; substantially as described.
2. In a razor-stropping device the combination with the supporting-frame
In testimony whereof I have hereunto affixed my signature this 9th day of February, A. D. 1900.
