SAFETY-RAZOR.

Specification of Letters Patent.

Patented March 27, 1906.

Application filed May 26, 1905. Serial No. 262,404.

a very simple and effective type of safety-' razor so constructed that two removable and interchangeable blades are employed which when placed in a body-frame back to back present two opposing cutting edges, the blades being primarily sha ed for. the purpose intended and made 0 sufficient thickness to admit of beveling their cutting edges, which bevel is so deep that the blades can be repeatedly honed, ground, and stropped with the best results.

Another purpose of the invention is to provide a frame constructed in detachable and adjustable sections and to provide simple and conveniently-operated fastening devices for the frame, whereby as the blades are lessened in width by reason of repeated sharpening the sections of the frame can be adjusted -to maintain proper relation to the blades.

It is also a purpose of the invention to provide removable clamps for the blades and fastening devices for the clamps readily accessible andconveniently operated.

A further purpose of the invention is to so construct the razor in its entiretly that all of its parts may be separated, enab ing them to be readily and quickly cleaned and rapidly and conveniently assembled and secured in assembled position.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 'is a perspective view of the improved razor, drawn upon an enlarged scale and viewed from the back. Fig. 2 is a central transverse section through the bodyframe of the razor and the blades, the handle appearing in side elevation. Fig. 3 is a central lon itudinal section throng 1 the bodyl'rame of the razor, the handle and fastening devices for the sections of the frame appearing in side elevation. Fig. 4 is a plan view of a section of the body-frame. Fig. 5 is a per spective view of one of the clamps for the blades, and Fig. 6 is a plan view of oneof the blades.

The razor consists, primarily, of two blades A, a body B, and a handle C. The blades A. are made of plate-steel and are sufficientl thick to prevent them from bending. Each blade is provided with a bevel section 10 upon both of its side faces at its cutting edge, as is particularly shown in Fig. 2, and between the said bevel-sections and the heel of each blade a slot 11 is produced in each end of a blade. In the construction of the blade the back edge or heel thereof is made perfectly straight.

The frame B is constructed in three sectionsnamely, a central bar-section b and two wing sections 6, adapted to be located one at each side of the bar-section. The said bar-section bis provided at each side adjacent to its under face with flat surfaces 13, a ainst which the rear edges or heels of the b ades 10 abut when the said blades are in position on the frame. The bar-section b is provided at each end with a horizontal threaded aperture 14, and "these apertures'l are adapted to receive the threaded shanks of set screws 15 for a purpose to be hereinafter mentioned. The bar-section b of the frame is further provided with a. central threaded aperture 16, extending through from back to front, and with a similar aperture 17 at each side of the central aperture 16, as shown in Fig. 3. The apertures 17 receive the threaded shank'portions of setscrews 18, and the central aperture 16 receives a threaded stud 19, extending from the outer end of the handle 0, as is also best shown in Fig. 3. The set-screws 18, acting in conjunction with the hold the sections of the frame B together.

Each wing-section b is constructed as particularly shown in Figs. 2 and 4. The wingsections are made of sheet metal brass, for example-and each comprises a horizontal member 20, provided with a central slot 21 and with slots 22, one at each side of the cen-' tral slot, the said slots being produced in. the inner edge of the saidmember 20, extending quite close to its forward edge; A guardsection 23 is integral with the horizontal section 20, which may be termed the body-section of a wing, and this guard-section 23 handle C, serve to curves downwardly and more or less outwardly from the body-section and then u wardly, the outer longitudinal edge of t e guard member being nearly in a plane with the outer edge of the body-section 20, as is shown in Fig. 2. The guard member 23 of a wing b is transversely slotted, forming thereby a number of guard-fingers 26, the upper ends whereof are bent outwardly and downwardly, forming a series of hook-terminals 27.

In assembling the parts of the razor, suposing all of the parts to have been separated, the handle 0 is loosened and likewise the setscrews 18. Then the body portions of the wings I) are passed one over the other beneath the bar-section b in such manner that the threaded shank of the handle C will enter the central slots 21 in the wings and the slots 22 of the said wings will receive the threaded shanks of the set-screws 18. The blades are then laced in position on the wings, the back or eel portions of the blades bearing firmly against the flat longitudinal faces of the barsection b, while the cutting edges of the blades are adapted to be supported upon the upper end portions of the guard-fingers 26, as is shown in Figs. 1 and 2. After the wing-sections b of the body-frame have been adjusted so as to be in proper relation to the cutting edges of the blades the handle C and setscrews 18 are screwed tightly to place, so as to clamp the body portions of the wing-sections 6 firmly against the under face of the bar-section b. The blades A are now in position; but it is necessary that they should be held so while in use. To that end a clamp D is provided for the ends of the blades, two clamps onl being necessary, as a clamp at each end 0 the body-frame will engage with both of the blades.

One of the clamps D is shown in detail in Fig. 5, and said clamps are preferably made of sheet metal, such as brass. A clamp D consists of a bar member 28, having an upwardly-extending ear '29 at the central portion of its upper edge, the said ear being provided with a smooth aperture 30. At the bottom central portion of the bar member 28 a horizontal inwardly-extending foot 31 is formed, while at each end of the bar member 28 an angular finger 32 is produced, the horizontal member whereof extends inwardly, so that when a clamp is in position on the bodyframe the horizontal V 32 will extend over t1e upper faces of the blades at their edges. In applying these clamps one clamp is first laced at one end.

of the bodyframe, and the orizontal portio of the angular fingers 32 are pressed over the outer faces of the blades A at that end of the razor-frame, the vertical portions of the said angular fingers 32 being received in the slots 11 at that end of the blades.v

portions of the fingers When a clamp is be opposite the threaded aperture 14 at the end of the bar-section b, and-the clamp is held in place by the set-screw 15 at that end being passed through the aperture in the clamp and screwed into the aperture 14 in the bar, as shown in Fig. 3 and likewise in Fig. 1, at which time the foot member 31 of the clamp will extend inward beneath and in engagement with the under face of the lowermost body member -20 of a wing section 1). Finally, the clamp D for the opposite end of the body-frame is placed and screwed in position in the same manner ashas been described with reference to the opposing clamp.

In order to enable the blades to be accurately and speedily set upon the wing-sections of the frame, lugs 32 are formed upon the hook-terminals 27 of the end guardfin gers 26, against which lugs the cutting edges of the blades are made to bear at their end portions.

The safety-razor constructed as above is very simple, its parts are all firmly held together when assembled and locked, and it is possible at any time to expeditiously and conveniently separate all the parts for cleaning or remove one or both blades for sharpening purposes, and as the blades become narrow through wear the guard members of the wingsections may be adjusted properly relative to the edges of the blades.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. A safety-razor consisting of a bodyframe constructed in two sections adjustable relative to each other, an intermediate connecting member for said .sections, blades placed back to back and locked to the intermediate connecting member, being supported at their cutting edges b the two adjustable sections, means for ing the blades in osition, and adjusting devices for the said rarne-sections.

2. A safety-razor consisting of a central bar-section, slotted upwardly-curved wingsections mounted u on the bar-section for movement to and ffiom eachother, blades placed back to back on'the bar-section above said wingsections, their cuttin edges resting u on the wingsections, an locking devices for the wing-sections and the said blades.

3. A safety-razor consisting of a central bar-section, slotted wing-sections adjustably mounted upon the bar-section, blades having retaining connection with the bar-section and supporting engagement with the wingsections, locking-clamps for the ends of the blades, and a handle adapted for connection with the bar-section.
