face of the large cam-plate 25. The engagement of this cam-lug and roll will operate at the proper time, presently to be. mentioned, to break the clutch engagement of the driving-pulley and collar 37 and stop the Inachine.

37a is a coiled spring` on the driving-shaft 23 to bringabout the rengagement of collar 37 and pulley 24.

The lever 3S is jointed at e, so that its forward or free end 38 may be raised sufficient to clear the roll 10 from the cam-lug 41, and thus allowthe spring 37 to bring about such rengagement.

The operation is as follows: The knife is placed in position shown at Fig. 4, with the cutting edge down, and while the forward end of the frame is elevated. When, therefore, the cam-plate 25 has been turned to bring the roll 27 on the lowest point of said camplate, the back of the knife-blade will be just below the center of the glazing-wheel, and when the machine is started the blade is reciprocated rapidly across the face of the wheel, while at the same time the knife-supporting end of the frame is being gradually raised by the cam-plate 25, and when the said camplate is in the position shown at Fig. 4 the edge of the knife-blade will have been raised above the center of the glazing-Wheel and the operation of glazing on that side of the blade will have been completed. In the meantime the cam-plate will still continue to lift the forward end of the frame and carry the blade above the glazing-Wheel until the highest point of the cam-plate has been reached, when the engagement of the roll 40 of the cam-lug will stop the machine. The knife is then reversed by placing the handle in the hook-supports 20, so as to glaze the opposite side of the blade. The forward end 38 of the lever 38 is then raised to disengage its roll 40 from the cam-lug 41, and-thereby, as before mentioned, restart the machine. As the cam is at this time at its highest point, the first impulse of said cam in its rotative movement will be to cause the roll 27 to drop from the highest to the lowest point of the cam. This drop will bring the knife-blade again into operative position with respect to the glazing-wheel, and the side of the blade nearest to said wheel will be finished` by the two motions above mentioned-viz., the reciprocating and elevating. The pressure of the blade against the Wheel is regulated by thenutsl. Compressingthetension-springs 8 and 9 lightens the pressure, while elongation of said springs increases the pressure.

It will be observed (see Fig. l) that the reciprocating bar 17 is thinned down at the point 17h immediatelyunder the knife-blade. This is done to give a little spring of the bar at that point.

While I describe the machine as a glazing-machine, it will be understood that by simply changing the wheel it is applicable for grinding knife-blades.

From the foregoing description it will readily be seen that the machine, being automatic blade, beginning at the back, isl drawn backward and forward across the face of the wheel, and at the same time the blade is gradually rolled toward the edge, thus preserving this convex surface. In my improved machine this conveXity is preserved by the circular movement of the frame oscillating on the bar 3.

It will readily be seen that the adjustingrods 11 and 12 could be dispensed with, and the spring-rods 8 and 9 could be threaded a portion of their length sufficient to effect the necessary adjustment of the head 4 to and` from the bar 3.

Having thus described my invention, what I claim as new,and desire to secure by Letters Patent, isy 1 In a machine of the character described, comprising, in combination with a polishingwheel, an oscillating frame, adapted to be automatically operated, a support therefor, an automatically-reciprocatingknife-supporting slide mounted on said head, means for gradually elevating the knife-carrying end of said i frame while the reciprocating knife-support is in action, for the purpose set forth.
