RAZOR-STROPPING MACHINE.

' No. scan-11.

Specification of Letters Patent.

Patented June 30, 1908.

To allwhefln it may concern:

Be it known that I, AUGUsT \VILLIAM SCHEUBER, a citizen of the United States, residing in Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Razor- Stroppin Machines, of which the following is a ull, clear, and exact specification.

My invention relates to machines for stropping razor blades and is articularly useful or stropping detachable lades such as are used in many safety razors. It may also be used for stropping the blades of ordinary razors.

The invention has for its object to provide a Si111pl6,&11(l. economical structure wherein the blade shall be securely held and exposed,- with slight movement, to the action of the tra and wherein tie blade holder is dicct T connected with, and controlled by, the friction roller, and thereby doing away with gears and separate s rings to operate and return the parts, an providing a structure which is not liable to get out of order nor Wear out quickly.

The invention consists in a pivoted bladeholder and a pivoted friction roller adjacent and. directly connected thereto by a connection which rocks the blade holder in the opposite direction to that in which the friction roller is rocked, and by the spring action of which the blade is quickly returned to central position.

It also consists in sundry details of cons'truction hereinafter described and illustrated in the accompanying drawing, wherein Figure 1 is a side view of my improved stropping machine, partly broken away; Fig. 2 an end view t iereof; and Fig. 3 a vertical section taken 0 the line 33 of Fig. 1.

The side frames 1, 2, are connected by a series of rods 3, 4, 5, 6, and 7, and by a supporting loop 8. RodS is principally a connecting or .ytrcngthening rod, although it also serves 'to maintain the strop in posit-ion. Rods 6, 7, guide the strop and maintain it in pro )er position to engage the blade.

pon the rod- 5 is mounted the bladeholder 8, which, as illustrated, is made of a single piece of stiff material adapted to hold its shape and possessing resiliency such as thin sheet iron or, steel, although, of course,

IZdo not confine myself to a single-piece structure. 'This blade-holder 8 is constructed with a central, longitudinal channel 9,

'vided with the blade-receiving lips 10, W

formed by bending out its material, and into this channel rod 5 enters, and ermits the blade-holder to rock freely t ereon. Upon its lower side the blade-holder is roare bent substantially to the siape of the I back of the blade to be held, and owing to the slight-spring of the sheet metal, will hold the blade firmly. The upper end of the blade-holder is formed into a tailiece or feather 1 1, through which the bladeolder is rocked and returned to central position.

A- semi-cylindrical friction member 12 is mounted to rock freely upon rod 4, and this is perferably formed of material such as is used for the blade-holder. This rocker has an upper friction surface 13 over which the strop 18 passes, and its lower part, on each side, is formed into wings or flanges 14, which receive the tail-piece 11. Midway of its length each of the wings 14 has a portion of its material separated by slots from the main body forming spring tongues 15, which are pressed toward the center and are in close contact at all mes with the feather -11, preventing all play of the latter and always tending to press the blade to central position out of contact with the stro The blade 16' is inserted in tlie holding lips 10 of the blade-holder from the end, and to permit this the side frames 1, 2, are cut away, as at 17, thereby forming two pendent portions in each. frame, which receive the connecting and strop-guiding rods 6, 7, at their lower ends.

The operation of my device is exceedingly simple and certain and will be readily understood. The strop and blade being in position and the device being suspended by the loop 8, the strop is grasped at the ends by each hand and pulled first one way and then the other, and the strop, bearin on the friction rocker 14, will cause the biade to be rocked, bringing it into position to be stropped by the descending side of the strop: c. 9., in Fig. 3 the left-hand portion of the strop is moving in the direction of the arrow, and the razor is then rocked to stro ping position in contact with that part of't 1e strop. This will cause rib 11 to press the oppositely disposed spring tongues 15 apart (Flg. 3), thereby flexing said springs and operating to return quickly the blade to central position the instant the movementof the strop is reversed. A reversal of'the movement will cause the razorto engage the opposite part ofthestrop. -This arrangement ossesses many advantages, among others, t e quickness of responseof the razor to the. friction rocker; the absence of play between them; the doing away with wire parts of the frame forming the inner walls of recesses 17 may form sto s to limit the rocking movement of the b adeholder.

It is obvious that many modifications and changes may be made in my invention without departing from the spirit thereof, and I do not mean to limit myself to the gxact construction shown and described,

What I claim and desire to secure by Letters Patent is;

1. In a stropping device, strop guiding means, a'friction rocker disposed in operative relation to the strop, pendent flanges on'said rocker, spring ton ues in said. flanges, a blade-holder pivota y supported in said device, blade-holding means in said blade holder, and a projection therefrom adapted to be received between said pendent flanges and to be embraced by said spring tongues, substantially as described.

2. In a stropping device, side frames, strop guiding and connecting rods mounted therein, a friction rocker mounted to swing therein, pendent flanges thereon, spring blade-holding lips therein, a blade-holder mounted in said frames to rock, and a pro-I j ection' adapted to enter between the flanges and to be embraced by the spring tongues of the rocker, substantially as described. v

3. In a stropping apparatus, a rocking device having spring tongues, and-a blade holder having a projection adapted to pass between and be embraced by the said spring tongues and to flex the same when oscillated, substantially as described. *4. In a stropping device, side framesrecessed at their lower parts, strop-guiding rods connecting said lower parts, a friction rocker mounted to swing in the frames, integral flanges" depending'from said friction rocker, spring tongues in said flanges, a blade-holder mounted to rock in the frames, a projection therefrom adapted to pass between said fianges and spring tongues, and spring blade-receiving lips, said projection and ii s formed in one piece, substantially as descri ed.

5. In a stropping device, side frames 1 and 2, recessed at 17, connecting" and guiding rods 6 and 7,. connecting and bearing rods 4 and 5,.friction rocker 3 on rod 4, pendent flanges 14 and. spring tongues 15 integral therewith, blade support 8 on rod 5, comprising rockin feather 11, hearing channel 9, and spring ho ding lips 10 in one piece, said lips 10 extending within recess 17 substantially as described.

In testimony whereof, I have hereunto set witnesses.
