4stropped bybein-g placed between adouble and face butted endless belt strop 11. The belt 11 is mounted onpulleys v12 and 13, the former of which is power driven, being mounted for. that purpose on a rotary shaft 14, .which is provided with suitable bearings in the frame 15 of the machine. `13 an idler, and is mounted on a vertically.. disposed shaft 16. The pulleyflf is pro` vided witha bushing .17 to forma bearing for the diminished section of the shaft 16,'

The pulley as shown bestin Fig. of the drawings.

rl `he shaft 16 is upbent from a'threaded` ortlon 18, the threads whereof are -engagedby the threads of anut 19. The end of the portion l18 beyond the threaded section 'is provided with a guide block 20, 'whic eX- tends `within the' rectangular tubul` ramevr 15. By means` of Athis constructionitis ob- Vious that the separation of` thjeypulleys 12 y and 13 may be ivaried` 'at-twill, therebv increasing or. diminishing the tensii on the l belt `11. A The belt 11 is illustrated in the drawin as composed of two duplicate belts, ithe hair sides of which are `laidtcgether andthey esh sides of .which are outwardly disposed.

This arrangement of thebelts forms a very convenient manner of protecting the same against settlement of dust on the surface thereoforming-.a grit unnatural and unde; sired. This .is particularly truev when the strop surfaces are dressed or otherwisev pre;

pared. v v -f i --As shown inFig, 7 of the drawings, the

frame is provided .with a hand hold 21,` which may be grasped by the hand of the' operator, andthe shaft 14 is providedwith` dit ssl.

a Acrank attachment 22. The attachment l22 4 is mounted on the' Vsquared end 23 of the shaft 14 sothatthe handle- 21 may" be `ro.

tated to drive thebelt 11, 11. In thisl manner thev machine isV hand-loperated,j landf manipulated.

The blade A1 Ais pl'aedwiithin a cup heide-r 24. The ciip'hoidef 24g-fis mountedfon a stationary' arm 25, being provided with a sleeve arm 26` whichffii'tsfover the "armf25' 'and is secured thereo I armjis provided with ajsc'rew threaded endy section 28, having afshoulder 29 t o` rest again'stthe side ofjtheframe 15y when the tions in'thesa'idyramemsshown in, yiglof the drawings. The fed section 28 is screw' threaded to receive a nut whereby the end section and the arm 25'lconnected therewith are clamped rigidly in adj ustedaposition. The sleeve 26 and the clip holder 24 connected therewith are rocked to throw theblade A Vfrom side to side on the pivotal center of the arm 25, forcing outwardly alternately the said

belts

11, 11. The lateral swing ofthe blade when mounted in the clip holderl 24 is equal on each side of the pivotal center of the said arm, and this because of the fact that the oscillation of the sleeve 26 is mechanically produced. The sleeve 26 has an off set arm'31 extended fromthe lower end of the said sleeve. The arm 31 is loosely'c'onnected by means of a screw 32 with the eye leted end of a connectin 'rod 33. The rod 33 is bent to any suitab e shape, and is secured to the pulley 12 by a screw 34 set out from the center of the said'pulley 12. The disposition of the screw 34'with reference to fthe center of the pulley 1'2 regulates t-he throw of the arm 31 and the sleeve 26 connected therewith. The connection between the screw 34 and the rod v33, it will be understood, is a loose `or pivotal connection. v 1. A'

When using the short or safety type of blade, the same is introduced within the clip holder 24, much in the same manner as the l, same type ofblades are placed within the `hand stropping devices now 1n use. .When

-manipulated manually, the operator so disposed, and when the machine is being the handle 21, as shown .in Fig. 7 drawings, and turns the crank 22 rapidly or slowly, as desired. The turning of the crank 22 when fast to the shaft 14 rotates the

pulleys

12 and 13 carrying the

double belts

11, 11 constantly in one direction. 'The pulley 12 carries the screw 34 about the v center of the said ulley, and by reason of l'GIS the connectin ro 33 connecting the said pulley yand s eeve 26, the said sleeve is rocked on the arm 25 carrying alternately Ato opposite sides of the median line of the

belts

11, 11, the holder 24 and fblade A mounted therein. 'It will also be observed that the arm 25 is disposed in angular relation to the travel `of the belt, :as seen in Fig.

:7. The angular disposition of the arm 25' is varied by loosening the nut 30 and setting-y the arm 25 to the desired position, and then the said nut 30. The. connection ti htenin v of the roi? 33'with the arm 31 and the pulley 12 is suiciently loose to provide for a suitable'and desired'adjustment of these'parts without cramping. It is obvious that with the operation of the crank 22 the blade 'A is alternately forced against the outer and inner belts l11,11, supporting` the same and receiving on the edge of the blade the full tension of the said belts. Also, by reason' lof/the inclined disposition of the arm 25jit will be observed that the blade is constantly' the tray 35 may be slidably mounted 48 that the disk 46 is secured.

and steadilyheld in the most' favorable posi-l tion for 'receivin the most perfect edge. When the st-ropplng has proceeded to the desired extent the machine is arrested .and the blade A withdrawn from the clip holder 24.

.When the long blade or exposed blade type of razor is stroppedfthe-blade is inserted between the clip holder 24 in the same `manner as that above described with reference to the short or safety razor type,\but there `is provided a further handle holding device or tray 35. The tray 35 is provided with a supporting rod 36. The rod 36 is providedvatthe lower end with a slide 37. The slide 37 is locked in position onthe frame 15 :by means of a clamp 38, the sa'id' clamp being at will forced against the frame 415 by setting u the screw 39. Seek articularly Fig. 8 o the drawin for t is construction. By

it will be seen that the slide-37 may be ad! means oft is Vconstruction justed lengthwise on 1tliessframe 15, tofsuit the disposition ofthe blade/A and the handle B t ereof'.. .If desired, means for retain. ing the handle B in the tray 3 5 may be provi ed. Also, for convenience `of ackinlg, ont e rod 36 and secured lengthwise thereon by-a set screw 40, as seen in Fig. 7 of the draw-A ings. The operation, as far as stropping is concerned, Vwhen using the machine forsharpening razors of the long blade type, is

similar to the operation above d ribed as `when using the machine to Sharpe blades of the short or safety razor type.

When thev machine is attached for\me chanical manipulation there is provided a stand 41,'-upon which'is suitably mounted -a supporting frame 42, between the 'arms whereofV is clamped the frame15, using for that purposeVt a wing nut" 43. Suitably mounted :tlieMs'Etand 41 is an electric motor 44, upon the amature shaft of which is mounted a suitable friction. pulley 45. The pulley 45'4is arranged and provided to rotate on alfriction4 disk 46 to thereby rotate the'shaft 14. The shaft 14 is operatively connected `with the disk 46 by a shaft 47 The shaft 47 is /clampedin' fixed relation to the disk 46 by means of a screw-nut 48.' The shaft 47 is provided with a pivotal extension 49,v which 1s rotatively mountedin a standard 50 suitably arranged d 'xedly secured on the. stand Q41. Th shaft 47 may be adjusted vertically by means of a collar 51, which is slidably mounted on the e'xtension 49 of the said shaft, and which is fixedly secured thereto by means-of a set screw 52.- AIt is betweenthe collar land the nut When the machine is mounted -in connec-v v vtion with the 4mechanical means above described, the o consists in holder 24, and turning on the electric current for the motor 44. This having been accomplished, and the motor having gathered headway, the barber is at libert-y to attend to any other office in his profession whilefthe' razor is being stropped. Further, the stropping-is executed more evenly and `more quickly thanby the hand methodat 'present used. Further, it Will be seen that\ the stropping may be continued to an extent beyond 'the endurance of the ordinary operator, thereby-giving to the blade a finer and more perfect edge than imparted by the nect'ingl 4usual hand method.

Having thus described my invention, what Iclaim'as new and desire to secureby Letters Patent is 1. A razor stropping machine, comprising a plurality of overlaid face-bu'tted endless stropping belts; a plurality of pulleys to'supportsaid belts; a frame to support `said pulleys; a blade holding device disosed between said belts and supported on said frame; lrneans for adjusting said blade holding device in inclined relation to said belts; an arm laterally extended from said Vblade holding device; a pitman rod 'consaid arm and one of .sai pulleys to rock t e said blade holding device; and a' tray supported on said frame for holding the handle of a folding razor when the blade thereof is held by said blade holding device'.

2. In a. razor stropping machine a straight bar frame provided at the one end thereof with a. holding handle; a plurality of shafts mounted on said frame and extended perpendicularly therefrom; a plurality of pulleys mounted on said shafts in `Tit-ned relation; a plurality of-overlaid face butted endless stropping belts mountedon said pulleys; a blade holder pivotally mounted in said frame and extended between.l said belts in an inclined position therein, said= blade holder having an extended arm; a pitnian ypivotally connected with the said pulleys at a point relnoved from the center tllereof and the said arm extended from: said blade holder; and means 'connected `with one of said. pulleys for rotating the saine to clrive the said belts and reciprocate vthe said pitman.

In testimony whereof I have signed this specification in the-presence of two subscriblng Witnesses.
