In the drawings, G'is a razor blade which may be of any usual or desired type and which, in the present instance, is shown as being of the double edge type. It will be distinctly understood,.however, that the device, while particularly desirable for stropping this type of blade, is not limited in but may be used for ropping single edge-blades.

manner to a suitable is mounted to rock ab hearings provided in the fra 'Also journaled in suitable bearings in the frame 8,,1 provide a pair ofstropping drums, which are designated by numbers 9 and 10. Preferably, the blade andits holder are mounted between the drumsin such a manner that as the blade is rocked ton-nil fro both sides of ,both edges of the blade will be stropped without removingthe blade from the holder and reversing the same. i

To operate the blade holder and the drums, I- provide a suitable manually op eratable actuatingmember 11 consisting of a wheel iourna'led on the blade holder 7 and provided with a crank 13. This crank may be or detachably attached-t preferably the latter, in the present .instanc wheel as being provided with lateral projecting pins 1%, 14 fitting into r e respectively, provided in the crank 12. The wheel 11 is connected with the drums 9' and 10 to rotate the same and for-this purpose I employ suitable gearing pr-eferab y of the meor casing 8.-

either permanently o the wheelll and and for this purpose, e, I have shown said spur type so that the driving connection be-' journaled on studs ms the proper rotation to correspond with the positions assuinedby the blade with-respect thereto'fTThe wheel 11, which constitutes the driving member, is connected to the bladeholder by suitable frictional rotary driving means which, inthe "present instance, consists of a spring. washer 25 interposed. between the wheel 11 and a collar 26 fixed on the holder 7. The

riction of the driving proper amount of f surfaces is obtained by means of an adjusting nut 97 having screw-th'readed engageand an adment with the blade holder 7 screw 28, the head of justment locking against said nut and locks. the

12 having {lj' handle cesses 15. 15.

of these intermediate "The operation" of the stropping device liereinbefore specifically describedis as follows: Assuming that the blade is in place on the holder with the crank 13 attached to the wheel l1, the user holds the frame or easing 8 in one handjor places the same upon a suitable support and with the otherhand grasps the handle 13. 'He then rotates said rhandle alternately in opposite directions,

preferably'several rotations in each dircc-' 't1 o11. Assuming that at the start, thecblade occupies the position shown in Fig. 4c. and

the handle is rotated clockwise, Fig. 2, it will be evident that the drums 9 and .10 will be positively rotated by reason of the gearing connecting the same to the driving gear 1.6,whileat the same time since the connection between the gear 16 and the blade holder? is' a-slippin'g driving connection, a slipping *action will immediately take'place, since the blade is in connection with the drums 9 and-10, and it will be evident that this frictional driving connection which'has' just been referred to forms a meansior furnishing the desired pressure of't he blade against thestrop'pingdrums.

I If now, after several turns of the handlein a; clockwise direction, the direction. of the handle'be reversed-itwill be evident that .the position-- of the blade will be reversed,

since the blade will move freely across the intervening. space between the drums until the blade-occupies the position shown in Fig. ,5, whereupon the blade encountering the drums, ceases to rotate, is held with the *p'ropenpressurelagainst the drums, and the drums are then rotated inan opposite direc -tion for, in other words, counterclockwise.

The operator continues to rotate the handle alternately in opposite directions until the blade has been sutficiently stropped, after which the blade may be removed from its qholder.
