JULIUsu. rncns,or SEATTLE, wasnumron.-
To all whom it may concern:
Be i-t known that I, .lomos U. Focus -a citizen of the' United States, resil at cattle, in the countyV of King and te of- Washington,-haveinvented a new and 'useful Improvement inv Blade-Sharpenin Attachments for Phondgraphs, of whic the following is a specification.
.The primary object of 'my invention is to utilize the motor-power employed for driving the rotatory table which supports the record-disk in 'a phonograph, for sharpent ing blades, and more especially safety-razor blades. To that end my invention is an attaclunent comprising a pair of stropping or honing members geared 'together to be "rotated on their axes in relatively opposite directions by rotation of the table, and a blade-holder connected with the gearing to be'os'cillatorily actuated to bear against the opposite edges of a blade held in the holder alternately against the aforesaid members.
In the accompanying drawings, Figure 1 is a broken plan view of a phonograph with my attachment in place thereon; Fig. 2 is a plan View of the attachment with the topplate of the frame removed to display the gearing and other parts-g Fig. 3 is a front end view of the attachment; Fig. lis a view in elevation of the supporting leg and top plate of the attachment; and Fig. A5 is a section on line 55, Fig. 1, showing the blade-holder and other parts in elevation.
The frame of the device, when constructed as shown, though itniay 'involve any other suitable construction, has a top-plate 7 witlr a lil-shaped leg 8 on one end provided with an 'expanded bas; l. A thumb-screw 10 secures the leg and the plate together` and `isfastened by a nut 11. A rectangular bracket 12 is secured at one end to the vunder side of the plate 7 near its rear end and is provided at its opposite forward end with an expanded base 9a, on a level with the base 9. A shaft 13 is journaled in the base 9a and bracket 12 and passes through the plate,l below which it carries a relatively large friction drive-wheel 14 adapted to be adjusted up and down on the shaft and fas- 50 ytened by a set-screw 15 in itsiadjusted position. In a relatively small rectangular bracket 16 secured to the underside of the plate near its forward end is journaled a shaft/13* extending parallel with the shaft lili ,'13 and thrpugh'the plate. These two shafts y:itrgetlrer by corresponding .u nr'racmmnr ron. Pnonoamrns.

l I l toothed wheels 417, 17 secured on them below the plate; and each carries, above the plate, and, removably, a cylindrical razor-'.
stroppingor razor-honing Sharpener 18. Thepurpose of rendering t ese members removable, as b withdrawing each lengthwise from its s aft, is to adapt the s tropping cylinders to be substituted for the honing cyllnders 'and vice versa The shaft 13* 85 carnes on its lower end a pinion 19 meshing wlth a relatively large toothed wheel 20 journaled on the under side of the plate 7 near its cen-ter and carrying a semi-circular cam 21 in position to engage the adjacent 70 end of a spring-pressed arm 22 pivoted at its opposite end, at 23, to the under side of the plate near the rear end of the latter.A This arm carries between its ends a finger 2l projecting upwardly through an elon- 75 gated transverse'sloti25 in the plate 7.
-A shaft 26 rises rigidly from the top of the frame-plate behind and on a line midway between the Shafts 13 and 13a and carries, to be oscillated,\a blade-holder 27 30 having a rearwardly-extending tail-piece 28, through an openin in which the finger 2i projects. This hol er has a pair of fol'- Wardly converging spring jaws 429, 30. A screw- 31 projects from the inner face of 85 the jaw 29 through the companion-jaw 'and carries a thumb-nut 32, by tightening of which as afety-razor blade 33 may be clamped between the jaws in position to cause oscillation of the holder to bear the edges of the blade to be stropped or honed alternately against the Sharpeners 18. An adjustable gage 34 is provided on the outer face of the jaw 29 for properly setting the blade in the holder.
The operative position of my attachment is on the platform 35 of -a phonograph, to' which it issecured, at'the bases 9 and 9, adjacent the rotating table 36 for carrying the record-disks. In that position, when the 100 attachment is outofuse the Wheel 14 is held by the set-screw in a plane 4dii'erent from that occupied by the record-table. When it is desired to use the attachment, after adjusting in the holder 27 a blade to be sharp- 10b' ened, the wheel 14 is adjusted onjthe shaft 13 into position to contact its perlphery with that of the table 36, driving of which by the phonograph-motor drives the parallel s afts 13 and 13a in relatively opposite directlons, 110 andthe gear 2O to rotate the cainl. In one-half oi'each revolution of this. gear'20 the anni beerl v:ignimit the :irin und turns it, in opposition to its spring, in e direction wherein resultant engagement of the linger 24; with the teil-piece 28 turns the bledeholderto bringl one edge of the blade to be sharpened against one of the two rolls or Sharpeners 18. "At the end of that lia-lf of rotating sharpening medium during onehnlf o'j the revolution ol the gear 20, thus for n sullieient length of time is the stroppinp; or honing operation against each eide of the blade-edge.
The blade-holder may he readily lifted off its supporting shaft for lnnidling it in removing a. sherpened blade and adjusting n blade to be sharpened between the holder jews; and it muy be as readily returned to its operative position.
I realize that considerable variation is possible in the details ol' construction thus specifically shown and described, and l do not. intend'by illustrating n. single speeiie embodiment o'iny 'invention to be limited thereto, my intention being in the following' 'claims to claim protection upon ell the nov! elt)v there muy be in 'my invention' :1s fully ne the stilte of the nrt 'will permit.
