- riage 7 is a second dove-tail track: 9 which extends transversely of said carriage and receives slidahly thereon a second carriage 10 which is thus movable arallel with the axis of the grinding whee l 5. The under side of the carriage 10 is provided with a rack bar 11 received sliclablyin a slot 12 formed through the track 9, said barnieshing with a pinion 13 on the inner end of a shaft 14 which projects rotatably and slidably through a bore 15 formed through the front portion of the track 6, said track being recessed at 15 to permit the pinion to move back andforth with the carriage 7 as the latteris adjusted. The outer end of shaft 14 is provided with a' hand wheel 16 by means of which it may be rotated to cause the pinion 13 and rack 11 to adjust equipped with a vcrticaldovetail track 20' receiving thereon a vertically moving can.
be groundriagc 21 which carries the Work-to as will be described.
An archedmatrix support22 straddles the track 17 and rises from the carriage 7,
said support having above the track 17 apair of seats to receive matrices 23 and24 which are held in place by screws or the 1ike'25 as shown clearly in Figs. 2 and 8. Each matrix is providedv yrith one irregular edge as will be clear fr'oi'n Figs 3 audit is the til-inaction of these edges to move the carriage 18 along? the-track l7 and to shift the carriage'2l a. (mg the track 20 agains'tth'e tension of coiled springs 26 and 27 respectively, thus causing the work carried by the carriage 21 to move in the proper direction with respect to the wheel 5 for impart in the necessary formation to said, work.
fiihe carriage 18- is provided with a roller QE'traVeIing-on the irregular edge of the i 23 while the correspondin edge of matrix 24 receives thereon a rel er 29 on the lower end-0f carriage'Q-I so that these two carrlages are moved in the required manner against the tension of their springs 26 and 27 respectively.
The springs in question may be mounted any preferred manner but the inner endsthereof preferably bear against abutmente 30 and 31 secured respectively to the outer end of the carriage 18 and the upper end of carriage 21, the outer ends of said springs being received slidably in tubular, housings 32 and 33 secured respectively to the true cs 17 and 20, adjusting screws 34 and 35 being threaded through the outer ends of said housings for varying the tension of the springs 26 and 27 as occasion may require.
A bracket arm 36 is secured by screws or the like 37 to the carriage forwardly therefrom toward the grinding edge of the wheel 5, the outer end of said arm having a horizontally'extcnding split bearing 58 receiving rotatablytherein the arbor 39 of a work holding head 40, said head being preferably in the form of a flat metal block flanged at its ends at 41 and having suitable stop pins 12 and clamps 43 for securing blades or The arbor 39 as shown extends parallel with the shaft 4 of the grinding wheel 5 and may be locked against possible rotation by tightenin the set screw 45 of the split bearing 38. store tightening the screw, however,
1 the arbor is temporarily locked against movement by means 116w to be described.
A disk 46 is carried rigidly end of the bearing 38 and a threaded into an opening in said disk, said screwpassing throu h an arcuate slot 48 in a second disk 49 w ich contacts with the other and is rigidly mounted on the outer end of the arbor 39 so that after the head 40 has been properly adjusted, the parts may be locked in this position temporarily by tightep'ing the screw 47, screw 15 being then tightened to lock the arbor against possible turning.
The head 40 is provided with two sets of stop JlDS 12 and clamps 43 in'order that two b ades such. as el may be ground with-' out varying the position of the matrices '23 and 24, thus insuring that the two blades be by the outer of exactly the same contour. This is highly essential when grinding the blades of ma chines such as those used for turning heels,
since it is necessary that both blades of the right as well as the left hand arbor be of the exact shape.
In operation, the blades to be 'groundare clamped upon the head 40 as depicted clearly in Fi 2 and the carriage 7 is then fed orward y the required amount to properly .10- cats the uppermost of said blades with re spect to the periphery of the grinding wheel 5. This havin been done, the set screw 8 of'the carriage is locked and the set screws 34 and 35 are turned to place their respective springs .26 and 27 under the required ten sion. The wheel 5 is now or previously set in motion and the carriage 10 is fed along the tr'ack9 by means of the wheel 16 so that the blade being ground is moved back and forth across the wheel 5. During this more 21' and extendsening the first blade.
the like a l in place.-
screw 47 1s shaped face,
the blade being ground as to cause the grinding wheel to impart the required shape thereto. After the uppermost blade has been ground, the head 10 is inverted by loosenin the screws 15 and 47 so. that the other b ade may be sharpened while the matrices 23 and 24 remain in the same positions in which they were placed while sharp- This insures that the cunvl-ature of both blades shall he symmetrica After sharpening, say a pair of right hand blades in the manner above described, the matrices 23 and 2 1 may be reversed and the machine will then be in condition to sharpen,
a pair of left hand blades, the operation being the same.
Screws 8 and 8 similar to the screw 8 are by preference provided in order that the carriages 18 and 21 may-be locked against movement So that the machine may be employed for grinding straight surfaces when required, it being understood that no matrices are then needed and consequently, the springs 26 and 27 may be thrown out of action by loosening their respective screws 34 and 35.
From the foregoing, taken in connection with the accompanying drawings, it will be clear that although the invention is of rather simple and inexpensive nature, it willjbe highly efficient and durable. For these reasons, the construction shown end described constitutes the preferredform of the ma chine but it is to be understood that within the scope of thcinvention as claimed, numerous changes may be made without sacri ficing the principal advantages.
