To all whew it may concern:
Be it known that I, August William 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-Stropping Machines, of which the following is a full, clear, and exact specification.
My invention relates to machines for stropping razor blades and is particularly useful for stropping detachable blades 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 simple and economical structure wherein the blade shall be securely held and exposed, with slight movement, to the action of the strop, and wherein the blade holder is directly connected with, and controlled by, the friction roller, and thereby doing away with gears and separate springs to operate and return the parts, and providing a structure which is not liable to get out of order nor wear out quickly.
The invention consists in a pivoted blade-holder 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 construction hereinafter described and illustrated in the accompanying drawing, wherein

A semi-cylindrical friction member
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
It will be observed in
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 exact construction shown and described, but
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 tongues in said flanges, a blade-holder pivotally 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 projection adapted to enter between the flanges and to be embraced by the spring tongues of the rocker, substantially as described.
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 frames recessed 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 flanges and spring tongues, and spring blade-receiving lips, said projection and lips formed in one piece, substantially as described.
5. In a stropping device, side frames
In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses.
August William Scheuber.
