9, Claims. (c1. 51-211) This invention appertains to new and useful improvements in the art of abrading, and more particularly to a novel stone holder.

The principal object of this invention is to provide a stone holder wherein the stone is' revolvable in oil or some other suitable lubricant. Another important object, of the invention is to provide a stone holder wherein the stone will'always be maintained sufliciently lubricated, and cleaned or washed oi adhering particles caused by abrading.

Anotherv important objectof the invention is to provide a stone holder provided with means whereby the stone can be retained in the desired angular position to suit convenience, such as for presenting the abrading surfaces for abrading of a tool or other object and for presenting said surfaces to the oil for lubricating the same and for cleaning or washing the same of adhering 90 particles mentioned above.

Other important objects and advantages of the invention will be found in the following specification and claims.

In the drawings:---

Figure 1 represents a perspective view of the novel unit.

Fig. 2 represents a perspective view of the stone proper.

Fig. 3 represents a cross sectional view of the assembly.

Fig. 4. represents a longitudinal sectional view through the assembly.

Fig. 5 represents atop plan view of the stone holder. Fig. 6 represents a cross sectional view of the "assembly.

ferring to the drawings wherein like numorals designate like parts, it" can be seen that the invention includes a rectangular shaped trough or container 5 having a circular opening 6 in one end wall thereof and a vertically disposed slot 2 in the opposite end wall thereof.

Numeral t represents the elongated stone having the slabs a-a secured. to a pair of opposite in Fig. d The threaded pintle is disposed through the slot 7' while the smooth pintle is disposed through the one s. a winged nut 11 is engageable on the threaded pintle and adapted to be" tightened against the adjacent end of the trough 5 for securing the stone 8 in a suitable or predetermined position convenient to the user.

Numeral 12 represents the oil which is prei- 'erably of a baseless value and which always has the stone 8 with its lowermost iace immersed therein.

Obviously, the stone can be retained against rotation by the winged nut 11 and when desired, the winged nut can be released and the stone moved or rotated to the desired angular position, whereupon the winged nut can be again tightened for securing the stone in the angularly set position.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes inthe shape, size and materials may be resorted to without departing from the spirit and scope of the invention as planned hereinafter.

Having thus described my invention, what I claim as new is:

l. A stoneholder comprising a frame, a ,stone provided with a pintle at each end thereof, said frame being provided with an opening at each end thereof for receiving the corresponding pintles, one of said pintles being provided with threads and aunt seatable on the threed pintle and against the frame to bind the adjacent end of the stone against the irameto prevent rotation-thereof, the opening at oneend of the ire through which the threaded pintle extends being in the form of a notch laterally through which the threaded pintle may readily be removed when the nut is loosened.

'2. An abrading device comprising a. receptacleconstructed and arranged to maintain a body oi oil of substantial depth therein, a stone; pintles embedded in and projecting from the end portions as of said stone in line with the axis thereof, said pintles being rotatively mounted in the upper portions of the end walls of said receptacle in such manner that the stone is rotatable within the receptacle, and a clamp member, one of pintles and said clamp member having complemental means constructed and arranged to tightly hold the contiguous end of the stone in non-rotatable frictional engagement with the 1% inner surface of the adjacent end wall, said box, said stone and said pintles being so relatively positioned and arranged that as the stone rotates the faces thereof will be lubricated d i also washed of foreign particles, and portions no of the stone are submerged in the oil while the stone is at rest. v

3. An abrading device comprising a receptacle constructed and arranged to maintain a body of oil of substantial depth therein, a stone having a plurality of sharpening faces, pintles projecting from the end portions of said stone in line, with the axis thereof, said pintles being rotatahly mounted inthe upper portions oi the end walls of said receptacle in such 7-"- :m that the stone may be rotated in a complete circle to selectively bring said surfaces to the top of the receptacle, and a clamp member, one of said plntles and said eaaeaa clamp member having complemental means constructed and arranged to tightly hold the con tiguous end of the stone in non-rotatable fricwith one of said faces in an approximately hori- 20mm plane at th t Jam
