Elijah E. Deputy, of Wilmington, Delaware, assignor to Dilworth B. Perry, of Wilmington, Delaware. Machine for Stropping Razors.
No. 869,068. Specification of Letters Patent. Patented Oct. 22, 1907.
Application filed February 7, 1907. Serial No. 356,209

To all whom it may concern:

Be it known that I, Elijah E. Deputy, a citizen of the United States, residing at Wilmington, in the county of Newcastle and State of Delaware, have invented a new and useful Machine for Stropping Razors, of which the following is a specification.

This invention relates to machines for stropping razors and its object is to provide a simple, durable and efficient device of this character which will quickly sharpen a razor blade and which will automatically reverse the blade upon the sharpening surface whenever the movement of said surface is reversed.

A still further object is to provide a machine having a sharpening device formed with surfaces of different materials either of which may be used for sharpening the blade.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a perspective view of the device and showing a razor in position thereon prior to the rotation of the sharpening disk; Fig. 2 is a vertical section therethrough; and Fig. 3 is a section through a portion of the disk and showing one of the positions assumed by the razor blade and its holder during the rotation of the disk.

Referring to the figures by characters of reference, 1 is the tubular body of the device having jaws 2 and 3 extending therefrom and adapted to engage the edge of a table top or other support. A set screw 4 extends through one of the jaws for the purpose of engaging said support. A sleeve 5 is secured, as by means of a set screw 6, to the upper portion of the body 1 and has an angular bracket 7 extending therefrom. The upstanding portion 8 of this bracket is formed with a longitudinal slot 9.

Rotatably mounted within the body 1 is a shaft 10 having a crank arm 11 connected to the lower end thereof while the upper portion of the shaft is formed with a collar 12 which bears against the upper end of the body land acts as an end bearing. A screw threaded stem 13 projects from one end of shaft 10 and through a central aperture 14 formed in a holding disk 15. The ends of this aperture are countersunk as at 16 to receive one end of shaft 10 and a holding nut 17. Secured to one face of the disk 15 is a hard grinding or sharpening disk 18 of stone or other like material and a disk 19 of leather is secured upon the opposite face of the disk 15. By binding the holding disk 15 between the end of shaft 10 and the nut 17 the same can be caused to rotate with the shaft.

Extending through the slot 9 is a threaded stem 20 projecting from one end of a spindle 24. This stem carries a winged nut 22 by means of which the stem can be secured at any desired point within the slot 9. A tube 23 is loosely mounted on the spindle 21 and has an inturned portion 24 adapted to engage an annular shoulder 25 on the spindle so as to hold said tube against longitudinal movement. A spring clip 26 is formed at one end of the tube 23 and is so proportioned as to embrace the back edge of a razor blade 27 and hold said blade in position above the sharpening disk and at one side of the center thereof. The edge of the blade is adapted to project beyond the clip so that it can contact with the sharpening disk.

In using the device herein described the disk 15 may first be secured to shaft 10 with its hard sharpening surface 18 uppermost. The spindle 21 is then pressed toward the sharpening disk so as to cause the tube 23 to frictionally engage said disk. The parts are then locked by means of the nut 22. After the parts have been positioned in this manner the razor blade 27 is inserted into clip 26 and the shaft 10 is rotated by means of crank 11. This will cause the sleeve 23 to-partly rotate and swing the blade downward on to the sharpening disk which will revolve thereunder and in contact with the blade and quickly sharpen it. By reversing the movement of the disk the tube will be turned in the opposite direction so as to swing the other face of the blade against the sharpening disk. It will therefore be understood that by rotating the disk in opposite directions both faces of the blade will be automatically applied thereto. After the blade has been sufficiently sharpened the parts can be detached and the disk reversed so as to bring the leather disk 19 uppermost. The foregoing operation can be repeated and the razor blade will be thoroughly stropped. It will be seen that the device is very simple, durable and efficient and can be readily operated.

What is claimed is:

1. A device of the character described comprising a rotatable sharpening element, a rotatable device frictionally engaging said element, and a blade receiving clip movable with said device.

2. A device of the character described comprising a rotatable sharpening element, an adjustable rotatable device frictionally engaging said element, and a blade holding clip movable with said device.

3. A device of the character described comprising a rotatable sharpening element, a rotatable device adjustably mounted adjacent thereto, means for holding said device in frictional engagment with said element, and a blade engaging clip movable with said rotatable device.

4. A device of the character described comprising a movable sharpening element and a movably mounted blade holding device frictionally engaging said element and disposed to be actuated thereby to direct a blade onto the sharpening element.

5. A device of the character described comprising a movable sharpening element, means for actuating the same in opposite directions alternately, a blade holding device movably mounted adjacent, and frictionally engaging said element, said device being disposed to be actuated by the sharpening element to direct a blade onto said element.

6. A device of the character described comprising a bracket, a sharpening device rotatably mounted adjacent the bracket, a spindle adjustably connected to the bracket, a rotatable device upon the spindle and disposed to frictionally engage said element, and a blade engaging device movable with said rotatable device.

7. A device of the character described comprising a body, means for securing the same to a support, a sharpening element rotatably mounted upon the body, a rotatable device frictionally engaging said element, and a blade engaging device movable with the rotatable device.

8. A device of the character described comprising a body, a bracket extending therefrom, a shaft rotatably mounted within the body, a reversible sharpening element connected to the shaft, a rotatable device adjustably connected to the bracket and frictionally engaging said element and a blade engaging device movable with said rotatable device.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
