SAFETY-RAZOR.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application iiled February 3, 1966. Serial No. 299.278.

To all whom it may concern; I

Be it known that I, FREDERICK H. AE- NoLD, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

This invention relates to improvements in safety-razors; and the object of my present invention is to provide a device of such arrangement and dimensions that it may be easily carried in the vest-pocket without inconvenience.

The present device is intended more particularly as an improvement on the devices shown and described in my pending applications, Serial Nos. 275,514 and 290,701.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawings, in which- Figure 1 shows my device complete closed. Fig. 2 is a longitudinal sectional view of the device open and ready for use. Fig. 3 is a detail view of the backing-plate. Fig. 4 is a detail view of the guard-plate. Fig. 5 is a detail view of the blade. Fig. 6 is a crosssectional view taken on line a; :l: of Fig. 2 enlarged.

The numeral 1 designates a tubular casing having a reduced rear end 2. The numeral 3 designates a cone-shaped plug adapted to fit into the open end of said casing. This plug is reversible, as both its ends are adapted to engage said casing. The plug is screwthreaded internally.

The numeral 4 indicates the backing-plate, and 5 the guard-plate.

6 designates the razor-blade.

The backing-plate 4 is formed with an angled hook 7 at its outer end and a lug 8 near its rear end. The plate terminates in a tapered half-round externally-screw-threaded stem 9. The guard-plate is formed with a recess 10 at its outer end adapted to be engaged by the hook 7 and an opening llnear its rear end adapted to receive the lug 8. This plate is also formed with a corresponding half-round stem 12. The backing-plate is formed with a central longitudinal V- shaped rib 13, extending nearly its entire length, and the guard-plate is formed with a registering V-shaped longitudinal depression 14. The blade is formed with a recess l5 at either end adapted to register with the hook 7 and the lug 8. The blade is placed between the backing-plate and the guard, the hook and lug entering the end recesses and engaging the openings 10 and 11 in the guard-plate. The half-round stems are then insertedinthe screw-plug, and the drawing up of said screw-plug will compress thelplates, and the V-shaped rib willltend to drawthe outer edges of the blade into proper adjustment with relation to the guard-teeth.

The numeral 16 designates a cap adapted to fit onto the rear end of the casing 1. This cap is of sufficient length to carry a supply of reserve blades. When the razor is not in use, the plug is inserted in the casing with the plates inside thereof. as shown in Fig. 1, making a compact device. To use the razor, the plug is withdrawn and replaced in the casing in reverse position, as in Fig. 2. The cap 16 may be dispensed with when an additional supply of blades is not required.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a device of the character described, two plates, one of which is provided with a longitudinal depression and the other with a corresponding rib, a blade adapted to be clamped between said plates, means for securing together said plates at oneend, and means located at the opposite end for holding them compressed.

. 2. In a safety-razor, a guard and a clamping-plate, one of which 1s provided with a central longitudinal depression and the other with a central longitudinal rib, a blade adapted to be clamped between said guard and plate, means for securing together said guard and plate at one end, and means located at the opposite end for compressing and holding them.

3. In a safety-razor, a guard and a clamping-plate, one of which is provided with a substantially V-shaped longitudinal depression and the other with a corresponding rib, a blade adapted to be clamped between said guard and plate, means for securing together said guard and plate at one end, a plug located at the opposite end adapted to compress them, and a tubular handle adapted. to receive either end of said plug.

4. In a safety-razor a razor-blade, a pair of clamping-plates, one of which is formed with a central longitudinal V-shaped rib and a hook at its outer end, and the other with a corresponding V-shaped depression and a recess at its outer end for engaging said hook,
