Application filed January 16, 1922.-V Serial No. 529,597. i
Machine, of which the following is a specir`v ication.'
rllhe object oiu my invention is to piovide an improved machine for 'sharpening and polishingdisks; to provide the' novel devicev and combinations of `devices "hereinafter described.
It is further my object to provide an improved machine which is a disk Sharpener and polisher and which can be so adjusted as to sharpen the edge of the 'disk and polish or bud the inner surfaceoi the disk in one operation; or to polish the surface of the disk only; or to sharpen only, as desired.
It is further my object to provide a machine which is simple'in mechanical construction, durable, relatively inexpensive and easily operated. I attain theseand other objectsof my invention by thev mechanism illustrated in the accompanying drawings in which- Figure l is a side elevation of the invention showing two disk sharpening machines one of which is in position for grinding the disk and the other'ot which is in disconnected position with the machine tilted back in position to permit of convenient removal and replacement of the disk that is. to be ground;
Fig. 2 is a top plan of two disk operating mechanisms both in position for ypolishing or grinding the disks;
Fig. l is a plan view of the disk niuiler which I preit'er to employ.'
Iiike 'characters of reference indicate' like B indicates a conventional pedestal on whichY is mounted the shaft E carrying the drive pulley 'C and also carrying conventional4 emeryand polishingw'heel'sl Drive pulley C is driven by abelt D.
Referring Yto Fig. 1,' I provide a suitabley base '1 on whichris mounteda diskholding and operating pivot A disk"hfolder-`V iff is pivotallg;7- atof one of theY mechanism swingably mounted on the'base by a suitable hinge or' tached to the upper end of upright 2 and at the 'other end of the disk vholder al suit'- able hub 6, p'referablyhaving ball bearings, is provided on which the'disk l0 to be ground is attachedas shown in F ig'. 2. I may provide a suitable bracket 7 and clamping ring 8, secured in place by wing nut 9, for supporting the ball bearing hub member 6 on the endet the disk holder et, as shown in Fig. l. I provide a tension rod l2 secured by trunnions 1l to disk holder 4: and having its other end slidably engaged in bracket' or support member'lel. I also provide a compression spring 13 one endY of which bears against 'the bracket 14 and the otherend of which bears against 4the nut l5 adjustably mounted on the threaded portion of tension'ro'd 12 as lshown in F ig; l for'resiliently holding'the disk to operative engagement with the emery wheel while it is being ground and polished.A lI further provide a weighted lever 16 Amounted Vby means'of pivot 16 "on upright 2 and pro-` vided with cross armor othersuitable mem-l `ber 17 for engaging the disk holder 4. I
provide a-suitable pin 17}to act as a stop or support' for the disk holder 4f.A The other end 'of weighted lever 16 carries an adjustable weight 19 securedinthe desired place by Vasuitable set screw"-20. I further provide a dog or latch'22 pivotally mounted by any suitable hinge 24 to the upright` 2- and having its upper end releasablyY engagable in suitable notch'- 2l in vweighted lever 16 as shown in Fig. 1. The uppercnd of latch 22 is suspended from' the weighted lever by a' suitablyslidable link or support 23.
sharpening and polish-ing simultaneously,
I provide means for regulating the position or' and foroscillating the. upright 2 and v,conseqm-jntlythe diskk holder 4. Mv pre` ferred means foracconiplishingthisobject, as shown in the drawings, consists of plates '32 attached to upright?, and carrying guide pins 3l thatengagein longitudinal slots 31 in the'bracket 30 in which is mounted the threaded shaft or crank 33 which tune-f` ltionsas a strokeadjuster.`v` The adjustable bracket 30 is provided with`a`pinf29 with which one ot th'eslets 28 cfa? link or pitmanV` extension27is'lengaged; "Link27 mounted. y
by means of pivot 26 on the end of pitman 25 which extends through the pitman guide or support 34 and has its other end adjustably attached to the adjustable wrist pin plate or stroke adjuster 35 which is adjust` ably secured'by suitable bolts 36 on the pitman wheel 37 which in turn is mounted on the gear wheel 38 that drives the pitman and thus oscillates upright 2 and disk holder 4 to vary the point of Vcontact of the disk with the emery wheel A. Gear wheel 38 meshes with a pinion 39 mounted on shaft 40, lon which shaft the drive pulley 42 also is mounted and driven by the driving belt 43 as shown in the drawings. I provide a suitable support 44 on which the driving mechanism above described is mounted in the manner illustrated in the drawings.
As illustrated in the drawings I prefer to provide a pedestal B preferably of T-form whereby an emery wheel may be mounted on each end of the shaft E and driven by a single belt pulley at the center so that two disk polishing machines may be simultaneously operated; and when such arrangement is provided I also provide a jack 44 as shown in Fig. Q'arranged to drive two pitmen one connected with each of the disk holding mechanisms for simultaneously oscillating said mechanisms. It is, however, within the contemplation of my invention to build a machine in single form for operation on one disk at a time.
Referring to Fig. 4, showing disk muffler 48, this member is a disk of sheet steel provided with a suitable canvas padding 49, the device being designed to deaden the noise made by the disk grinding machine in sharpening and polishing disks, the muf-y fier being bolted on the disk that is to be ground or polished.
Referring to Fig. 2, I provide screw eyes 45 attached to uprights 2, and to which suitably braced rods 46 are secured, said brace rods being fastened to the floor by screw eyes 47, whereby to suitably brace uprights 2 without interfering with their oscillatory movement.
In operating the invention, thc uprights Q are moved to a rearward slanting position to permit of applying the disk l0 couveniently to the hub 6. When the disk l() and muflerl 48 have been secured on the machine the upright is then moved to an upright position, in which position the edge of the disk will engage with theemery wheel A for sharpening the disk. If the disk is to be polished, the extension 27 of pitman 25 is engaged with pin 29 of bracket 30, and the desired adjustment is secured by turning crank 33 which engages upright 2. Upright 2 is oscillatedby pitman 25 which is driven by gears 38 and 39, the latter being mounted on the driving shaft 40, as shown in Fig. 2. The disk 10 which is resiliently held to the surface of the emery wheel A is moved to and fro under the Grinding wheel and the polishing is thus quickly performed. An adjustment of nut 15 on threaded rod 12 will regulate the degree of spring tension used in holding the disk against the grinding wheel A, and regulation or adjustment to a further extent may be obtained by moving the weight 19 on arm 16, the reverse end of the arm by means of pins 17 and 17% engages the pivoted disk holder 4.
I claim-- l. In a disk sharpening and polishing machine, the combination of resilient disk holding means, a support on which said means is mounted, adjustable weight means, operatively connected with the disk holder, and means releasably holding the disk on the disk holding means.
2,.'In a machine of the class described, the combination of a pivotally mounted support, a disk holding device carried by said support, resilient means in connection with said disk holding device for resiliently supporting the disk in contact with a grinding wheel, and means for adjusting the disk holder, said means including a weighted arm.
