RAZORr-STROPPING DEVIGE. I

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed May 20, 1911.. Serial No. 628,539.

To all whom it may concern: a

Be it known that I, OHARLEY ELGRnnN WOOD, citizen of theUnited States, residing at McKinney, in. the=countyof Collin and State of Texas, have invented certain new and useful Improvements. in Razor-Strep ping Devices, ofjwhich the following. is a specification.

This invention relates to razor. stropping.

devices. a

One object istoprovide a device embodying such characteristics that the razor blade may be held upon an incline .to insurean efficient sharpening of the edge of the blade Another object resides in1the provision of a razor sharpening device embodymg com:

paratively fewparts with the various parts constructed and arranged for. easy and quick.

cooperation and with one movable part cush ioned at each limit of its movement to provide for an eiiective engagement of the razor blade witht-he strop.

With the above and other objects in view, the present invention consists in the con: struction and arrangement of; parts herein-1 after more fully described, illustrated in the accompanying drawings 1 and; particularly pointed out in the appended claim. it being:

understood that changes may be made in the form, proportion, sizeand minor details without departing from the/spirit or sacl'i ficing any of the advantages of the invention. a

In the drawings :-Figure 1 is a perspec other suitable device 14 whereby the casing.

may be secured to a book? (not shown) for operation of the device to sharpen the razor blade. The outer ends of theside pieces 1 and 2 are connected by the pairl of rods 5 and also by the outer rods 6to prevent spreading of the :outer ends of thel side pieces 1 and 2, there being guide rollers 7 mounted on the outer rods 6 as shown.

Mounted withinthe casing for swinging movement is a frame consistingof theends Fig. 4 is a face view. Fig. 5 is a;

8 and?) mounted on thepivot rod 1.0 which connects the side pieces 1 and 2 of the casing, the end pieces 18 and 9 being connected by the rods 11 and 12 on which are loosely mounted guide rollers 13 and 14 and also connected by a rod 15 to which latter and adjacent the outer faces of the end pieces 8 and 9 are secured the legs 16 and 17 of the blade holder 18, said legs 16 and 17 of the blade holder being mounted to swing on the rod 191which connects the side pieces 1 and :9 of the casing substantially intermediate the ends of the latter.: By virtue of the particularpivotal mountings of said frame and blade holder, the swinging movement of the frame inmone direction; effects swinging:

movement of the blade holder in the opposite directionfora purpose presently explained and as Will be brought out more in detail.

hereinafter. The leg117 of the blade holder 18 is shorterthan the log 16 and it will} be notedthat the difference in the length of the legsis to provide for aninclined disposition of the blade holder 18 withinthe casing and that the blade holder instead of being dis posed straightacross the casingis disposed upon an inclination so as to provide for an efiicient sharpening of the blade.

Connecting the side pieces 1 and 2 of the.

oasing anddisposed upon anincline substan tially parallel with the incline of the lower edge of the blade holder 18 are inclinedlrocls.

20 and 21 onwhich are loosely mounted the ihclined guide rollers 22 and 23, respectively go The blade holder 18 maybe of any, form desired, but as shown, it includes spring aws 24 and 25 and has mounted within it andsecured; in any suitable manner against the inner :face of its back a a fiat or other spring: 26 which has one end. bent to provide a 1 1 shoulder 27 to limit the inward movement of. if

the razor blade 28 whichlatter is positioned in the holder through the opposite end lot the. latter and through the open1ng;29 1n the side piece 2 of the casin The: character 30 indicates a leather or other-strop havingits ends provided with hand or finger rings 31 and 32. Tolposition 1 the strop it maybe done in various ways,

one :way being to insert the strop between 1 the bight portion 3 and the swinging frame. 1 andlpermit the strop .tolie adj acent. opposite sides of the casingandl onthe upper rollers a i 13 and 14 of the swinging frame. The end of. the strop having the ring 32 is then di rectedinwardly of the casing andunder the 1 "35 thess'trop -j Copies. bf this patent may be obtained for inclined roller 23 and down between the roll ers 7 and the corresponding rod 5. The-other end of the strop having the ring 31 is disa posed in like manner with respect to the opposite rod 5 and opposite rollers 22 and 7. The device is then in the condition illustrated in the drawings andbyengaging the attaching means 4 to a hook (not shown); and pulling von opposite rings 31 and 32 alternately the 10 strop is worked back and forth. In working thestropzback and forth and the strop being.

mounted on the swinging frame the latter caused to swing in opposite directions on its pivot 10 according to the pull onopposite ends offthe strop. This swinging movement of said'frame causes swinging movement of the inclined razor blade holder 18 in a di-' ;;;rection opposite totheswinging movement of ,the frame. For instance by pulling ,O'utr' 20 wardlyv. on the ring, 32 the "frame will be caused to swing :to the left whichwill result the blade holder being swung to :the right, gasvvill be seenin Fig. 15 and causing; the i b1ade 28 to be thrownagainst the innerface of the strop; By thennpulling'on the ringi.

' '31 Ithe frame will swing in the opposite di: rection ;;and cause an opposite swinging movement of the razor holder to dispose the s blade 28 against the inner face of the oppo- 30 1 site side of the strop.- In this way, the blade- I ,m'ay ibeieffectively sharpened to give it a proper shearingedge rather than a straight 7311p and down edge as whe'nzthe holderis'disposed to present. :the blade straight across The swinging movement of the 'frame is cushioned by means of the lugs 33 and 3t '1 -f11whichiproject through the openings 35 and 136 of theend piece 2 and which are formed.

4Oby bending; the extremities ofthe spring: rmemberi '35 secured by soldering; orrin' any;

i suitable manner to the outer face 'of' the'end lof'the'casing, the lower reduced'part' d; piece 9 of the swinging frame be- T ing so disposed as to engage said lugs 33 i I and 34 alternately according to the swinging a movement of the frame and the openings 7 through .xWh-lGll said lugs project being (of such size as to permit movement of the lugs, L

in the openingsyand effect an efiicient cush ioning action against the swinging frame.

This cushioning "actionipermits the blade to be pulled in proper tight engagement with the strop without danger of breakingany; part of thedevice. What is claimed is':-
