RAZGE-STRGPPH DE Application T 0 all whom it may concern:

Be it known that l, ELMER l. Yours, a citizen of the United States, residing at Montclair, in the county of Essex and State of New Jersey, have invented anew and ful Razor-Shopping Device, of which the following is a specification My invention relates to improvements in razor-stropping devices, and more particu- 19 larl to devices for shopping razor blades use in safety razors.

The objects of my invention are, first, to provide a stropping device simple in its construction, but positive in its action; second,

a stropping device in which there is no mechanism intermediate of the friction-roller and the blade-holder; third, to provide a. strepping-de'vice adapted to strop blades oi any thickness, with or without backs; fourth, to

20 increase the surface of contact between the friction-roller and the strop; andfifth', a stropping device that can be quickly and easily taken apart OT assembled.

Further and other objects will more definitely appear from the detailed description to follow.

I accomplish the objects of my i"ention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is illustrated in the accompanying drawings, forming a part of this specific-a tion, in which- Figure l is a top View of my improved shopping-device, showing a razor-blade held in one stropping position by the bladeholder. Fig. 2 is a side view. 3 is an end view, showing a razor strop and blade in situ. Fig. 4t is an enlarged perspective view of an auxiliary blade-holder.

In the drawing: similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, the frame of my improved razor-shopping device consists of a base-plate A and parallel standards I) D rigidly secured thereto,-said standards 1) 1) being connected to each other by the member I) and adapted to support a strep S. The base-plate A-is preferably formed from sheet metal, suitably shaped by bending the metal over upon itselfand bringing 5 the ends together at right angles thereto to base-plate i1 etporl van. a

so handici5 is drawings, erably l3. 7 lteinovably secured to and perpendicuh r thereto, spindles E lfi sonnet,

piece E. Upon the spur. I irevoluel mounted the blade-bolder l while u on the spindle l is revolubly mounted s trim to. tion-roll'er (5, preferably made or rubber, though any other suitable material may be used. Suitable means are provided for actuating the bladc-hohler by the roller C In the best embodiment of my invention, 1 arrange the spindles E E adjacent to each other, so that the roller G will be in trictional contact with tho blade-holder and the travel of the blade will be away from on either side or the roller .2. As shown in the u" drawings, i prefer to form the two swindl. it E integral with the connecting pi and reniovably secured to the base-plate A in a plane perpendicular to the plane o." standards D l The en s E pass through the base-plate clampin. nieniber C, where they rigidly e v a screw ll which.

es the notches r lower surface oi the roller u, so tl at w. the strop 5 passes over "the standa ds D E and under the roller G, it will tend. to envelop the roller G and thus largely increase the surface of contactbetween. the roller G and the strep. As the device is moved over the strap, the base plate A will act a guide, thus keeping the roller and blade- 10 holder transverse to the strep.

The blade-hol ler l may be of any desired construction adapter to tirinly hold a razor blade K. While bein, stropped. As shown, the blade-holder if is provided with two 10 spring which are adapted to receive-and hold firmly the back is of the blade K. l Vhen it is desired to strep blades having no backs, I provide an auxiliary blade-holder formed from strip of s metal bent over upon itself and having edges Z Z to engage the blade, entrance of the blade. This auxiliary bladeholder L is adapted to be inserted in the blade-holder F and to be heldiirmly by the jaws f f.

My improved stropping device is adapted to be used With the ordinary and well-known form of strop, which usually is a strip of leather. As indicated in Fig. 3, the strop S runs over the two standards D D and under the roller G. As the stropping-device is moved backward and forward, the friction of the strop upon the roller G causes the latter to rotate upon the spindle 1G and directly actuate the blade-holder 1 which will hold the blade K against the strep at the proper angle for stropping. As soon as the movement of the device over the strop is reversed, the roller G will reverse it rota tion 'hnd cause the blade-holder F to oscillate or reverse and assume the dotted position shown in Fig. 3. By removing the screw 11, the spindle E E can be withdrawn from the base-plate, in order to receive a new bladeholde or anew friction-roller if desired, and tie handle B can then be withdrawn. The parts can be reassembled in the reverse order.

While I have shown and described a device embodying my invention in the form preferred by me, yet it is capable of consid erable structural variation without, however, departing from the spirit of my IRVQHUOIL What 1 claim as new, and desire to secureby Letters Patent, is:

1. In a razor-stropping device, the combination of a base plate adapted to guide the strep, a handle secured thereto, for imparting bodily movement to the device, a

friction member to engage the strop, and bladeholderzin frictional contact with the peripheral surface of said friction member.

2 In a razor-stropplng device, the combination of a frame adapted to support and guide the strop, a handle secured to the frame for imparting bodily movement thereto, a roller to engage the strep, and a bladeholder in frictional contact with the peripheral surface of said roller.
