N° 21368 A.D. 1895

Date of Application, 11th Nov., 1909—Accepted, 14th Dec., 1895 COMPLETE SPECIFICATION. Improvements in Safety Razors

We, Frederick Kampfe, Richard Kampfe and Otto Kampfe, Manufacturers, of No. 8 Reade Street, in the City of New York, in the County of New York and State of New York, in the United States of America, do hereby declare of this invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement:—

This invention relates to improvements in safety razors. The object of our invention is to provide a new and improved safety razor which is so constructed that the lather can easily be removed and the razor thoroughly cleaned with great facility and a further object of our invention is to provide a skin stretching attachment which can readily be applied for stretching the skin in advance of the cutting edge of the blade.

In the accompanying drawings forming a part of this Specification and in which like letters of reference indicate like parts in all the figures.

Figure 1 is a perspective view of our improved safety razor provided with the skin stretcher.

Figure 2 is a vertical transverse sectional view of the same on the line 2, 2, of Figure 1, the skin, stretcher being detached.

Figure 3 is a plan view of the same, the skin stretcher being shown in dotted lines.

Figure 4 is a plan view of the same, the swinging top being swung back and the skin stretcher shown in dotted lines.

Figure 5, is a vertical longitudinal sectional view on the line 5, 5, of Figure 3.

The shell frame or casing A, for holding the blade C is made approximately U shaped in cross section, preferably of sheet metal and is provided at its top with a cross piece K at each end, which cross pieces connect the front and rear walls of said casing.

A handle B is provided at its upper end with a ball B¹ fitting in a socket B² having a threaded neck B³ which can be screwed into a threaded aperture in the bottom of the casing.

Each cross piece K is provided on its outer edge with an angle lug E, each containing an adjusting screw E¹ for adjusting the blade to project a greater or less distance beyond the front edge of the top of the casing.

The angle lugs E are bent over the upper surfaces of the cross pieces K and toward each other and the blade is confined between said angle lugs and the cross pieces K.

A spring latch D pivoted on the back of casing A bears against the rear edge of the blade C and presses same forward and against the inner ends of the screws E¹.

A top F provided with slots and having at its front edge bent prongs G, forming a guard comb, is hinged to the top edge of the rear wall of the casing A and is adapted to rest at its sides and near the front edge, on two screws H screwed through lugs J formed on the outer edges of the cross pieces K and bent under said cross pieces, as shown.

A spring finger M is made integral with said hinged top and is bent over the upper surface of said top, so as to press against the underside of the blade to assist in holding the same securely in place.

The screws E¹ and H can easily be adjusted by means of handle extension piece L which is provided in its closed end with a squared aperture for receiving the squared heads of said screws.

When the blade C is held in place on the casing A the cutting edge projects a greater or less distance beyond the curved ends of the guard teeth or prongs G which prevent the edge from putting into the skin.

After the razor has been used and the blade removed the hinged top can be swung up and easily wiped clean, thus facilitating the cleaning of the casing.

By means of the universal or ball and socket joints the casing A or blade can easily be adjusted at any desired angle most convenient for the person using the razor, thus rendering the operating of shaving very easy and pleasant.

The skin stretcher consists of an angle plate N having an aperture O through which the threaded neck B³, of the handle B can be passed for the purpose of holding said angle plate on the underside of the casing A, as shown in Figure 1 in full lines and in Figure 2, in dotted lines.

To the upturned front edge of the angle plate N a series of upwardly inclined prongs P are fastened the upper ends of which are a short distance from the ends of the guard teeth G, when the plate N is held on the underside of the casing and thus serve to stretch the skin in advance of the cutting edge of the blade.

In case the skin stretcher is not required it can easily be detached and the razor used without the same.

R is a holder for holding the blade while stropping it, the handle B which is unscrewed from the casing A serving as a handle for said holder R.

Having now particularly described and ascertained the nature of our said invention and what manner the same is to be performed, we declare that what we claim is:

1. In a safety razor, a blade holder having a hinged top provided at its front swinging edge with a guard, substantially as herein shown and described.

2. In a safety razor a blade holder provided with a hinged top having a spring finger on its upper surface and provided at its front edge with a guard, substantially as herein shown and described.

3. In a safety razor, the combination with a blade holding casing having two end cross pieces on its top and a hinged top between said end cross pieces, which hinged top has a guard at its front edge, substantially as herein shown and described.

4. In a safety razor, the combination with a blade holding casing, having a cross piece at each end of its top, each cross piece being provided with a downwardly bent lug, an adjustable stop in each lug, and a top hinged to said casing between the cross pieces to rest on said adjustable stops, said hinged top being provided with a guard, substantially as herein shown and described.

5. In a safety razor, the combination with a blade holding casing of a detachable skin stretcher held on the casing in advance of the front top edge of the same, substantially as herein shown and described.

6. In a safety razor, the combination with a blade holding casing of a detachable skin stretcher, substantially as herein shown and described.

7. In a safety razor, the combination with a blade holding casing, of a detachable handle and a detachable skin stretcher held on said casing by the detachable handle, substantially as herein shown and described.

8. In a safety razor, the combination with a blade holding casing, of a detachable handle and a plate having an aperture, through which part of said handle can be passed, and a series of prongs projecting upward from said plate, to the front top edge of the casing, substantially as herein shown and described.

9. A safety razor having a blade holding, case and a handle connected therewith by a universal joint, substantially as herein shown and described.

10. In a safety razor, the combination with a blade holding casing of a handle provided with a ball at the upper end and socket for receiving said ball, screwed into the bottom of said casing, substantially as herein shown and described.
