SCISSORS SHARPENER AND STONE HOLDER Filed Feb. 15, 1957 gwucmtov W TNESS Patented July 13, 1937 UNITED STAi'i'ES PATENT QEFHQE 6 Claims.

The invention aims primarily to provide a new and improved device of simple and inexpensive nature for conveniently holding an abrasive stone and accurately guiding scissors blades while 5 sharpening them upon said stone.

A further aim is to so construct the device that it may be effectively used for holding the stone in various convenient positions for sharpening knives and other edged tools without dan- 10 ger of cutting the: hands.

While I refer above to an abrasive stone, the invention may be used in connection with a file instead of a stone if desired.

With the above objects in View, the invention 15 resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawmg.

Fig. 1 is a perspective view showing the man- 20 her in which the device is used when sharpening scissors.

Fig. 2 is a vertical sectional view on line 2-2 of Fig. 1.

Fig. 3 is an end elevation illustrating another 25 manner in which the stone may be held for sharpening edged tools.

Fig. 4 is a side elevation showing still another of the various ways in which the stone may be held.

30 Fig. 5 is a plan view illustrating a file instead of a stone, held by the device.

A preferred construction has been illustrated and will be specifically described, with the understanding, however, that variations may be 35 made within the scope of the invention as claimed.

The numerals 6 on the drawing denote two flat elongated jaw plates each having a free longitudinal front edge 1 and each provided with 4.0 a central handle 8 integral with and projecting rearwardly from its rear edge. The two plates are pivotally connected with each other and moved toward each other by means of a C-shaped spring 9 having slots l through which the han- 45 dles 8 pass, the edges of said spring being hooked over suitable ribs II on said plates.

Both ends of each plate 6 are bent laterally outward in the same direction to provide flanges [2, each flange of each plate being at an obtuse 50 angle to said plate. The outer edges I3 of the flanges l2 are preferably straight as shown, and the front edges i l of said flanges are also preferably straight, these edges being free or exposed and being disposed in the same plane with 55 the front edge 1. The outer front corner of each (Cl. l214) flange I2 is provided with a log l5 projecting forwardly beyond the edge M.

When a stone S is positioned between the plates 6 in the manner shown in Figs. 1 and 2, the outer edges E3 of two of the flanges l2 will 5 rest solidly upon any suitable supporting surface to support the device and the stone in position to sharpen scissors, using either of the uppermost of the flanges I2 as a guide along which to slide the blade B while sharpening its edge upon the 10 stone. The free ends of the handles 8 are preferably so positioned with respect to the flanges 52 that when either pair of these flanges rests upon a supporting surface, the lowermost handle will also rest on said surface, whereby the handle assists the flanges materially in rigidly supporting the device and the stone.

When the stone is to be held with one of its flat sides entirely exposed as seen in Fig. 3, said stone may be so positioned that it rests against the front edges 1 of the plates 6 and the front edges M of the flanges: E2, the edges of the stone being then gripped by the lugs i5. With the stone. and the holding device thus con nected, said holding device may be readily held in one hand while the other hand is used for sharpening a knife or other edged tool upon the stone. Also, with the stone held as" shown in Fig. 3, either edge of said stone may be used for sharpening a scissors blade, using one or another of the lugs l5 and the contiguous portion of the flange !2 as a guide for the blade, and by thus using the edge of the stone, no channel will be worn in either flat face of said stone to interfere with sharpening other tools.

If any sharpening operation may be more conveniently performed byholding the stone in an inclined position with one of its edges disposed upwardly as seen in Fig. 4;, the holder may be readily engaged with said stone as illustrated in this view, the holder and the lower corner of the stone then resting on a suitable supporting surface.

If desired, the device may be used in connection with a flle F (Fig. 5) instead of with a stone, principally for sharpening scissors, the scissors blade being guided in the same manner as explained in connection with Fig. 1. If it be desired to slightly corrugate the cutting edge of either blade of the scissors, said edge may be rested lengthwise upon one side of the file and firmly pushed transversely of said file, in the direction taken by the cutting edges E of said file.

It will be seen from the foregoing that a novel device has been provided for carrying out the objects of the invention, and while the details. disclosed are preferable, attention is again invited to the possibility of making variations within the scope of the invention as claimed. Moreover, it will be understood that the device may be constructed in numerous sizes for coaction with stones of different sizes.

I claim:-

1. A device of the class described comprising two flat elongated spring-closed jaw plates to lie against opposite sides of an abrasive stone, said plates having free longitudinal front edges and being provided with handles projecting rearwardly from their rear edges for use in spreading said plates: apart, both ends of one of said plates being bent laterally outward to provide transverse flanges, the outer edges of said flanges being shaped to rest on a fiat surface to support the device and the stone, at least one end of the other of said plates being bent laterally outward at an obtuse angle to constitute a guide against which to slide a scissors blade while sharpening the edge thereof upon the stone.

2. A device of the class described comprising two flat elongated spring-closed jaw plates to lie against opposite sides of an abrasive stone, said plates having free longitudinal front edges and being provided with handles projecting rearwardly from their rear edges, both ends of one of said plates being bent laterally outward to provide transverse flanges, the outer edges of said flanges and the rear end of one of said handles being relatively positioned to jointly rest on a fiat surface to support the entire device and the stone, at least one end of the other of said plates being bent laterally outward at an obtuse angle to constitute a guide against which to slide a scissors blade while sharpening the edge thereof upon the stone.

3. A device of the class described comprising two elongated spring-closed jaw plates having free front longitudinal edges for disposition at one side of an abrasive stone, said plates being provided with handles projecting rearwardly from their rear edges for use in spreading said plates apart, both ends of each plate being bent laterally outward to provide flanges, said flanges having free front edges to abut said one side of the stone, said flanges being also provided with lugs projecting beyond said free front edges thereof to engage the edges of the stone to grip the latter.

4. A device of the class described comprising two flat elongated spring-closed jaw plates to lie against opposite sides of an abrasive stone, said plates having free longitudinal front edges and eing provided with handles projecting rearwardly from their rear edges for use in spreading said plates apart, both ends of one of said plates being bent laterally outward to provide transverse flanges, the outer edges of said flanges being shaped to rest on a fiat surface to support the device and the stone.
