UNITED STATES JOHN S. HOGG, OF ROCHESTER, NEW YORK.
SHARPENING DEVICE.
Specification of Letters Patent.
Patented Oct. '22, 1907.
Application filed March 23,1907. Serial No. 364,181.
To all whom 'L'Fmug concern:
Be it known that I, JOHN S. Hooo, a subject of the King of Great Britain, and a resident of Rochester, in the county of Monroe and State ol New York, have invented certain new and useful Improvements in Sharpening Devices, of which the following is a specilication.
This invention relates to sharpening devices and has for its object to provide one that is adjustable and particularly adapted for scissors.
The novel features of the device will be disclosed in the course of the description.
In the drawings:Figure 1 is a top plan view; Fig. 2 is an end elevai ion; Fig. 3 is a crosssection through a clamp and part of the stone and bed-plate, showing a scissors-blade in position; and Fig. 4 is a rear view of the sharpening stone and its support.
The bed-plate or base '1. is prel'erably made of sheet metal, with a downwardly turned flange 2 to stiffen it.
An openin it in the center of the base 1 admits a hook 4, through the lower end 5 of which a thumb screw 6 extends. By turning the thumb screw 6 the base II is clamped to the edge of a table-top or bench 7.
A semicircular slot 8 is cut in the base 1 near its front edge, and bolts 9 pass through it, and also through one member 10 of a scissors clamp of which there are two shown. Ea h clamp is secured in place by means of a thumb-nut ll and the heads l2 on a bolt 9. The cooperating member [13 of each clamp is adjustably held in place by a bolt [4; that is tapped into the member 10, and has a knurled head 15.
The clamps 1t), 10, if their respective thumb-nuts 11, ll, are loosened, may be moved to any points in the slot 8, and alined with each other, as shown in Fig. 1. By tightening said nuts 11, 11, ,the clamps are secured rigidly in place. One of the blades 16 of a pair of scissors is placed within both clamps, and lirmly secured therein, edge uppermost, (see Fig. 3) by means of the bolts 15, 15, after the clamps have been adjusted properly to receive it.
At each side of the base 1 a tongue of metal 17 is punched out and bent upwardly, so that said tongues l'orm supports for a horizontal guide rod 18. Slidably mounted upon the rod 18 is a block 15), that has two lugs 20, 20, with notches 21, 21, (Fig. 4) in thcirupper sides, rcspectivel y.
The sharpening stone 22, which is represented as rectangular in cross-section, is set in a metal socket 23, from the rear lace oi which projects a pin 24, with an enlarged end 25. The pin 24 is adapted to rest within the notches 2], 21, whereby the stone 22 is revolubly supported upon the block 19. The block 19 is itsell' revolubly supported upon the rod 18. Thus the stone 22 is capable of three movements, viz: a horizontal movement in a direction parallel to the axis of the rod 18; a vertical movement about said axis and in a direction at right angles thereto; and a rotary movement about the axis of the pin 24.
The scissors blade should be so adjusted that the stone when replaced will rest upon it and lie approximately horizontal (Fig. 2).
When the blade is in place the operator grasps the stone, and slides it back and forth along the edge of the scissors blade. The stops 2G, 26 prevent the stone from striking the free blade (not shown) which will hang vertically away from theclamps 10, and will also prevent the stone from slipping off the end of the blade that is being operated upon. Said clamps slant inwardly so as to hold the average scissors blade at the properanglc to the stone, when the latter is horizontal. (Fig. 3).
If the cutting edge of the blade is curved, as indicated by broken lines in Fig. 2, the stone will turn on the pin 24, and follow the curve, though keeping approximately the same angle with reference to it at all points. The pin 24 is placed near the bottom of the socket 23 so that the stone 22 may remain approximately horizontal as it nears the end of the scissors blade. Furthermore, the stone becomes adjustable as to height by the position of the pin 24 at one side of the axis of the stone.
To obtain the best results the scissors should be placed as shown in the drawings, at an oblique angle to the axis of the stone 22. However, the scissors may be placed in any desired position with reference to said stone, by adjusting the clamps.
What I claim is:
1. in a sharpening device, the combination oi? a suitable base; a horizontal guide rod supported upon said base: clamping means at one side of said guide rod, for supporting the blade that is to be operated upon; a block adapted both to slide and to rotate upon said guide rod; :1 grindingstick adapted for attachment at one end to said block and to overhang the blade in its support.
2. In a sharpening device, the combination of a suitable base, having an are shaped slot; a horizontal guide rod supported upon said base and subtending said slot; clamp in means movable in said slot and thereby adjustable with reference to said guide rod; and a grinder slidably supported by said guide rod and adapted to overhang said clamping means.
3. In a sharpening device, the combination 00a suitable base; a horizontal guide rod supported upon said base; clamping means at one side of said guide rod, for support ing the blade that is to be operated upon; a block adapted both to slide and to rotate upon said guide rod, and having a transverse slot therein; and a grinding stick adapted to overhang said clamping means and having a pin that protrudes from one end, parallel to and at one side of its axis, adapted to lie rotatively within said slot in said block.
4. In a sharpening device, the combination of a suitable base; a horizontal guide rod supported upon said base; clamping means at one side of said guide rod, for supporting the blade that is to be operated upon a block adapted 10 both to slide and to rotate upon said guide rod, and hav ing a transverse slot therein and a grinding stick adapted to overhang said clamping means, rectangular in cross section, having a pin that protrudes from one end, parallel to and at one side of the axis, adapted to lie rotatively within said slot in said block.
