Be it` knewn that l, EDWARD CYRIL BOWDEfSMiTH, a subject of King-.of Great Britain, residing at Careys, Brocken-k 5 -hurst, in the county of Hampslnre,`. England, have invented certain newV and`i'iseful 1mg 'provenients in Razor-Stropping Machines, of.- Wh'ich the following is a specificati -This invention relates to 'an-,1^

i l roved 'strulnents requiring a very sharpedg'e, and tomeans for carrying it into practice,V

The object of this invention -isvjte fren `erv "-thesuecessful stroppingrof a razer'independent ,of the skill of the operator and to con struct apparatus of a 'simple and efficient na-` ture in which the razor may be readily inserted and withdrawn after stropping; Theseobje'cts are attained. l yftlfelmechan 2o 'is'rnT illustrated in the accompanying drawings, in which Q Figurev 1, is an end view of the machine in elevation; Fig.' 2, is aside elevation 'of Fig. l;

provided attached to the roller 'A and a spring ratchet S is carried by the base E so as togear into thev ratchet teeth, thus allowing movementJ in onedirection only.

VThe razor holder is formed oftwo angular plates T, and T, embracing the lcross bar 'I between. them after the fashion Vof a hinge and combiningr togetherbeneath the cross bar to form the-jaws which grip the razor V;

as will seen from the. drawings, these jaws have a series oi corrugations so that they are adaptable to razor blades of diilerent depths or vso that the position of the blade against therollers may be varied. The jaws are kept closed on the razor bymeans of springs U, U1, in the upper portion oi the holder.` f

In operating the .niachine, the springs N N Iare ilrst pressed out or" the grooves O of the spindle J, which being released allow of the roller B being turned back as shown in Figj, (or as dotted in Fig. 2,); the .razor holder 'l,", T1, is then turned into the position shown inFig. 3,' andthe razor inserted, after which 1t V1s turned. downv again until the razor .touches the surface of roller A; thcroller B is then turned back into contact with A, and upon replacing .the springs. N in the grooves itvcompres'ses the cdge of the razor we tween the rollers; by turning the handle F', the stropping is eiiected and the razor may be withdrawn by'againreleasing the roller B.

Varices substances may be used as the `covering surface of` the rollers, for instance,

bluckfskin', leather, or any substance that is now in use on an ordinary strop for imparting a quicker stropping eil'ect to the razor. Paste or'powdersA maygalso be applied to the roller in' ,the-saineway, f

Ifam'aware that prior te'my invention razor strepping machines have been made with stropping rollers revolving on each side of a razor bladc and in slropping contacttlierewithlml therefor-edo net claim such a combination broadly, but,

'lfvfhat I do claim as my invention and desire to secure by Letters Patent, is: l

l. In a razor stropping' machine, the com binatioh with a roller covered with stropping material, ol a frame work having end plates with bearings for theI roller spindle, a cranked handle for turning same, brackets onthe end plates carrying Va cross bar, a razor holder pivoted ou the said cross-bar. a-Jsecond roller covered with stropping materi'al'andfineans roe 2o handle for turning same, brackets lalso pivoted 'on the cross bar rorsupporting 'same in removable and adjustable contact with the lirst mentioned roller.

" 2. In a razor stropping machine, the corn- 5 hination with a roller covered with strepping imaterial, of a frame-work having en'd plates `with bearings f'o the roller spindle, a cranked handle fortnrning` same, brackets on the .end plates carrying a cross bar, a razor holder le' pivoted on the cross bar, a second roller covered with stropping material, pivoted links carrying hearings for the second roller, forks in the end frames -lormin Y guides for the latter, and means for retaimng the roller in the i 5 said uides.A

S. n a razor stropping machine, the coin- -bination with 'a roller ooveredwith stroppingr material of a frame-work havin end plates with bearings for the roller spindlgie, a cranked on the end plates carrying a cross bar, a razor holder pivotedXon the cross bar, a second roller covered withstropping material, pivotedlinksy carrying hearings for the second roller, forks 2 5 in the end frames forming guides for the latter, a groove in the end of the second roller spindle7 a spring actuatedv angular lever for retaining the roller in the said guides, hinges for same, and a shoulder on the base against which the end thrust istaken.

4. In a razor stroppingr machine, the coin- 'ibination with two revolving rollers covered with stropping material, of .a traine l'or'sup- ,porting same, 'a crossbar supported by hraek- Iets on the said frame, a razor blade holder composed of two crossed plates so Vas to forni ivot on the cross bar, and means for envab' ing the`fsaid plates to vsecurely grip and holdthe razor between the revolving,r rollers.

4o K 5. Ina razor stropping machine, the combination with two revolving rollers covered v'with/s tro'pping material, oi a frame for sup# orting same, a ,eros/Shar supported -hy liraokets on the said frame, a razor holder eomposed. of two crossedplates so as to lorin a pivot on th(` erossfhar, and one or more coiled springs pressing outward on the crossed plates so es to canse the opposite ends of the plates/to grip the razor.

(i. ln a razor .stirnipingfl nmchine, the com` hination of a rollencovered with siroppinj.:

' material, with a framework having end plal es with hearings for the roller spindle, a cranked handle for turning same, a cross har snported adje-Gently tothe rollers, a rar/lor llolder connected to the cross lnlr having` spring actuated corrugated jaws to irl-ip the razor, a second roller covered with stropping material, links pivoted on the alinenien-l tioned cross har having hearings for the sec ond roller, forks on the end plates to not :is a

ping n1at(.rial,'links ypivoted on the alorementioned cross har having hearings for the second roller, lorks on the end plates lo :tot

as a guide lorrtheroller, spring actuated levers lor pressingr the rollers into Contact with each other,v and a ratchet wheel on one el" the rollers with a spring ratchet preventing the revolution ol' the rollers in a backwardv direc tion.

ln testimony whereof l have signed in v naine to this s'nei'lioation in the presence oll two subscribing witnesses.
