APPARATUS FOR FEEDING ABRASIVE MATERIAL TO GRINDING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 748,855, dated January 5, 1904.
Application filed April'27, 1903. Serial No. 164,411. [No model.) I
To all whom it may concern.-
Be it known that I, Isrnoa FLEXNER, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Apparatus for Feeding Abrasive Material to Grinding- Machines, of which the following is'a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification, in which Figure l is a vertical section of my improved apparatus. Fig. 2 is a horizontal section of the hopper on the line II II of Fig. 1, and Fig. 3 is a detail view showing the lower end of the agitating-shaft.
The purpose of my invention is to provide means for feeding crushed-steel abrasive to a grinding-machine for beveling the edges of plate-glass. It is important that this operation be performed uniformly and efiiciently, and the devices which have been heretofore employed for feeding sand and emery are not suitable for this purpose, owing to the peculiar difficulty of causing the crushed steel to mix with water.
In the accompanying drawings, 2 represents the frame of the grinding-machine, and 3 the rotary grinding-wheel driven by a shaft 4; and a. suitable pulley or gear-wheel 5.
0n the frame of the machine I mount a hopper 6, which is adapted to contain the abrasive material and has a discharge-nozzle 7, situate directly over the wheel and controlled by a valve 8, preferably a sliding valve, by which the discharge of material may be regulated or may be cut off altogether.
9 is a rotary shaft extending within the hopper driven by gearing 11 and journaled in suitable bearings 10 10. On this shaft within the hopper are radial arms 12 12, which rotate with the shaft and are adapted to agitate the material contained in the hopper. The base of the hopper is conical, as at 6, and the discharge-nozzle 7 is cylindrical. At the lower end of the shaft 9 is a triangular agitating-arm 13, having at its lower end a reduced extension or blade 14, the shape of which is shown in the detail view, Fig. 3. Water is supplied to the hopper from a pipe 15, and when the hopper is filled with the crushed-steel abrasive material the rotation of the shaft agitates the material and keeps the water mixed in and through it, so that when the valve 8 is opened a constant stream of mingled water and abrasive will be discharged upon the wheel, the rate of which can be regulated, as above stated.
Within the scope of my invention as defined in the claims the device maybe modified.
The combination with a glass-grinding machine, of a hopper having a conical lower end, a water-supply, and arotary shaft having agitating-arms within the hopper, and having a tapering agitating-blade at the conical part of the hopper; substantially as described.
In testimony whereof I have hereunto set my hand.
ISIDOR FLEXNER.
