To all whom it may concern:
Be it known that I, Albert L. Silberstein, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Razor-Stropping Machine, of which the following is a full, clear, and exact description.
The invention relates to razor-stropping machines for use with separate strops; and the object of the invention is to provide a new and improved razor-stropping machine which will readily accommodate handled razors having blades of different sizes and which is arranged to allow of conveniently placing the razor in position in the holder and securely holding it in place therein, the machine when in use giving the blade the desired inclined position while drawing it over the strop in either direction, so as to present the entire cutting edge of the blade to the strop at each forward and backward movement.
The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, in which similar characters of reference indicate corresponding parts in all the views.
On the forward end
The blade-holder
The frame
It is understood that when the arms
In order to limit the swinging movement of the frame
In order to accommodate razor-blades of different thicknesses in the same holder
Having thus described my invention, I claim as new and desire to secure by Letters Patent—
1. A razor-stropping machine, comprising a handle, having a fixed segmental rack and inclined shoulders, a frame pivoted on the said handle and having a pair of arms adapted to rest on the strop, the said frame having the flat back of its heel arranged to abut alternately on the said shoulders when the machine is in use, a blade-holder journaled on the frame between the said arms, and a pinion on the spindle of the said blade-holder and in mesh with the said segmental rack, as set forth.
2. A razor-stropping machine, comprising a handle having a fixed segmental rack and inclined shoulders, a frame pivoted on the said handle and having a pair of arms adapted to rest on the strop, the said frame having the flat back of its heel arranged to abut alternately on the said shoulders when the machine is in use, a blade-holder journaled on the frame between the said arms, a pinion on the spindle of the said blade-holder and in mesh with the said segmental rack, and a spring pressing the spindle of the blade-holder for returning the frame and blade-holder to a normal central position, the heel-back then being out of engagement with the said shoulders, as set forth.
3. A razor-stropping machine having a blade-holder provided with means secured to the holder and extending at the inside thereof for engaging the back of the blade inserted into the holder for pressing the blade outwardly and forcing the sides of the blade in firm contact with the sides of the holder, as set forth.
4. A razor-stropping machine having a blade-holder and a spring extending length-wise of the blade-holder along the bottom thereof for engaging and pressing against the back of the blade inserted into the holder, one end of the spring being secured to the blade-holder at the entrance end thereof, as set forth.
5. A razor-stropping machine having a blade-holder for receiving the blade of the razor and a handle-support mounted to slide on the said blade-holder so as to form an extension thereof, as set forth.
6. A razor-stropping machine having a blade-holder for receiving the blade of the razor, a handle-support mounted to slide on the said blade-holder to form an extension thereof, and means for limiting the outward sliding motion of the said handle-support on the said blade-holder, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
Albert L. Silberstein.
