MACHINE FOR GRINDING DISKS.
sPEcrFrcATIoN forming part of Letters Patent No. 723,051, dated Marci. 1r, ieo. Application filed November 29. 1902. Serial No. 133,221. (No model.)
To all whom, it may concern/r;
Be it known that I, ABIJAH T. SHIPP, acitizen of the United States, residing at Renner,
`in-the county of Collin and State of Texas,` r have invented new and useful improvements in Machines for GrindingDisks, ofwhich the following is a specification.
My invention relates to newand useful improvements in grinding-machines; and it is more especially adapted' for sharpening or A grinding the edges of concave-convex disks.
The object of the invention is to provide means for holding the disk rigidly at a desired angle, said holding means being adjustable from or toward a grinding device.`
Another Objectis to employ a novel arrangement of driving-gears whereby rotary motion may be imparted from the fixed shaft of the grinding device to the disk-holder, such 'transmission of` motion being unaffected by which will be more fully hereinafter described and claimed.
In the drawings, Figure 1 is a side elevation of the grinding-machine, showing a disk Fig. 2 is a vertical longitudinal `section through the machine. Fig. 3` is an end elevation. Fig. 4 is avertical transverse section on line 4 4, Fig. 2. Fig..5
. is a section through the adjusting mechanism of thedisk-holder. Fig. 6 is a section on line 6 6 of Fig. 5,`and Fig. 7 is a. detail view of the locking-plunger of the disk-holder-adjusting mechanism.
Referring to the figures by numerals of refi erence, 1 is a frameof any suitable form having a horizontal guideway 2 thereon, within which is mounted a slidable plate 3, having standards 4 thereon. A shaft 5 is secured in ment withthe flange by means of-a spring"11. The socket 7 is adapted to receive a pin 12, extending downward from the center of a beveled holding-gear 13, the upper face of which is `concave and preferably provided at the center with a vertical screw-threaded pin 14, upon which is mounted a thumb-nut 15. The gear 13 meshes with a beveled gear 16, mounted on the inner end of a shaft 17. This shaft is journaled in suitable brackets 18, arranged upon frame 1, and is provided at its outer end with a sprocket 19. A chain 20 extends over this sprocket and also over a sprocket 21, secured at the outer end of a stud-shaft 22, eXt-endinglaterally from a casting 2 This casting is suspended from and pivoted to a stud-shaft 24, projecting laterally from standards 25, secured upon frame 1 near the rear end thereof. A gear 26 is connected to and revolves with the sprocketwheel 21 and meshes with a smaller gear 27,
`mounted on a stud-shaft 28, located intermediate the shafts 22 and 24, before referred to. This smaller gear is also connected to and revolves with a larger gear 29, meshing with a smaller gear 30 upon shaft 24. A large gear 31 revolves with this gear 30 and meshes with a gear 32, which is arranged at the outer end of a shaft 33, journaled in standards 25. A grinding-wheel 34 is secured to the inner end of this shaft 33. A rod 35 is provided atopposite ends with sleeves 36, which are mounted upon the shafts 22 and 17, respectively, and this rod serves to hold said shafts at'the same distance apart at all times. If desired,however,suitable adjusting means, as a turnbuckle 37, may be provided upon the rod, so as to permit the chain 20 to be tightened by pressing said shafts apart. The slide `3 is provided at its forward end with an internally-screw-threaded ear 38, which is engaged by a screw 39, journaled in a standard 40, and provided at its outer end with a crank 41 or other means whereby the same may be readily turned. By means of this screw the slide 3 can be moved from or toward the grinding-Wheel 34.
A standard 42 is arranged upon the frame 1 near the rear end thereof, and a beam 43 is pivoted in the top thereof. An inclined bracket 44 is secured to the lower surface of this beam at the inner end thereof, and a IOCI roller 45, of rubber or other similar material, is journaled within this bracket and is adapted to bear upon the inner surface ot' the disk 46, which has been placed upon the gear 13, in the manner hereinafter described. This roller is normally pressed downward by a spring 47, which encircles a threaded rod 48, extending through the outer end of beam 43 and pivoted at its lower end to a rod 49. eX- tending upward from frame 1. A nut 5 0 is mounted on the rod 49, and by means thereof the tension of the spring 47'l may be regulated.` By providing a series of apertures 51 in the beam 43 said beam may be adjusted from or toward the gear 13.
In operation the disk to be ground is placed upon the concave face of the holding-gear 13, the threaded pin 14 extending through the aperture formed in the center of said disk. By screwingthe nut 15 down upon the disk the same is held firmly in position upon the holder 13 andv is prevented from rotating independently thereof.v The beam 43 is then raised andthe gear 13 moved inward toward the grinding-disk 34 by means of feed-screw 39. After the edge of the disk has been brought to a point belonT the roller 45 the beam 43 is released, and spring 47 promptly throws said roller into contact with the upper surface of the disk. Motion is then imparted to the grinding-wheel in any suitable manner, as by means of a belt arranged upon a pulley 52, and motion will be transmitted from the shaft of this grinding-wheel to the shaft of gear 16 by the train of gears arranged upon casting 23 and the chain 20. The gear 16 will revolve the holding-gear 13. By means of the feed-screw 39 the slide 3 and the gear 13` arranged thereabove, may be moved toward the grinding-disk, and the edge g of disk'46 can be held into contact with said disk until suflicientlygronnd. It will be understood that as the slide 3 is moved toward or from the grinder 34 the distance between the shafts 22 and 17 remains unchanged and the revolution of the gears 16 and 13 continues uninterrupted.
By means of the plunger 10 and the apertu red flange 8 the holding-gear 13 may be held at any angle to which it is adjusted. There'- fore the disk 46 can be fed to the grindingwheel 34 in such a way as'to secure an edge thereon of any desired bevel.
In the foregoing description I have shown the preferred form of my invention, but do not limit myself thereto, as I am aware that modifications may be made therein without sacricing any ot' the advantages thereof, and I therefore reserve the right to make all such changes as lfairly fall within the scope of my invention.
Having thus described-the invention, what is claimed as new is- 1. In a machine of the character described, the combination` with an adjustable gear for holding a disk, a grinding-wheel and means for imparting motion from said wheel to the naled upon the sleeve, and means for securing a disk upon the gear.
