To all whom it may concern:
Be it known that I, Charles F. Pluemacher, of Norristown, in the county of Montgomery and State of Pennsylvania, have invented a new and useful Improvement in the Manufacture of Razors, which improvement is fully set forth in the following specification and accompanying drawings, in which—
Similar letters of reference indicate corresponding parts in the several figures.
My invention consists of a razor-back formed tubular, with spring clamping-jaws, whereby the blade is securely held by said jaws, and its application to and removal from the back is accomplished by sliding motions, said blade having a projection, which engages with the tang for laterally bracing the connection of the blade.
Referring to the drawings,
The blank is placed on a mandrel and drawn thereover by hammering or otherwise, so as to bend the blank and form a tubular shape, (shown in
The back of the blade is introduced between the jaws
It will be seen that the back and tang are cheaply constructed, as they may be made at one operation and of one piece, and are strong and serviceable, there being no joint between them.
The back of the blade rests against the inner face or crown of the back
Should the blade break, and thereby or for other causes require removal, it is only necessary to draw or drive the blade from the back
By this construction, also, I am enabled to construct the blade of the finest stock, and make the razor lighter and cheaper than those formed of one solid piece of steel.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is—
