SAFETY-RAZOR.

Specification of Letters Patent.

Patented Dec. 20, 1910..

Application filed May 28, 1910. Serial No. 563,854.

To all whom "it may concern:

Be it known that 1, JOHN HmssnNBERenR, a citizen of the United States, and resident of the borough of Bronx, city of New York, in the county of New York and State of E New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

My invention has to do with safety razors of the general classin which a supporting frame is provided with an operating handle detachably secured thereto, and a locking means for retaining a cutting blade in operable position upon the frame.

It has as its novel features a spring operated means secured to or formed integral with the comb or frame for retaining the blade in proper position, and in a device for moistening the face of the operator in advance of the cutting edge of the razor.

Other novel features of greater or less importance will appear as the specification ad- The following is what I consider the best means of carrying out this invention.

In the accompanying drawings which form a part of this specification, Figure 1, is a plan view, showing the lower side of the razor. Fig. 2, is an end view partly in horizontal section showing the razor in operable position, the handle extending downwardly. Fig. 3, shows a modification. Fig. 4, is a plan yiew from the upper side, the blade being omitted for clearness. Fig. 5, is an additional modification; the operating spring is transverse with the one already shown.

Similar letters of reference indicate like parts in all the figures where they appear.

Referring to Figs. 1 and 4. A indicates a plate, which is the main operating member of the razor. The plate is flat except for the ends where a rib A is formed to secure suflicient rigidity in the plate A and to serve as a support for the cutting blade. The depth of the rib A varies for its entire length b'eing shallowest near the front edge.

Also formed integral with the plate A is the comb or guard A which is not unlikethe guard employed with safety razorsbf this general class, although I prefer that the downwardly extending portion of the guard A shall be short. Lugs A retain the razor blade secure against longitudinal displacement. They are bosses thrown up in the metal that forms the plate A. The lugs A,

A also formed integral with the plateA bear against the ends of the cutting edge of the blade and insure that the blade will not be forced forward beyond the guard.

The depressed central portion of the plate A is provided with slits b, 71 whereby the spring members B B and B result, and so that the three will have a nearly equal amount of flexibility I perforate the center {)nember in its thickest part as indicated Referring to Fig. 2 it will be noted that I have turned the outwardly extending ends of the outermost sections B B in such a manner as to produce a hook on each part, these hooks serving as bearings for the trunnions C C formed integral with the lever member C. The lever member or cam C is of an extended S shape and the trunnions C C are quite near the lower end. The upwardly extending longer part bears against the rear side of the razor blade and is sufficiently long to allow room above the blade for the engagement of the finger of the operator when itbecomes desirable to disengage the lever. The lower end of the lever is retained continuously in intimate contact with the center section B and it will be understood that the action of the lever is controlled by the springs B B and B D indicates the operating handle. Aboss A, formed in the plate A is drilled and screw-threaded on its interior and the upper end of the handle D is provided with a screw-thread matching closely the screwthread in the boss A The upper end of the handle is screwed firmly into the boss and adds greatly to the ease of operation.

A portion of my apparatus not before described but to which I attach importance is the moistener F and the parts immediately adjacent which assist in making the action of the moistener satisfactory and complete.

Referringuto Fig. 4, the moistener F, is shown as a roll, it may be of perforated sheet metal, or it may be of perforated sheet metal covered with a semi-porous fabric, or it may be made in a way which I deem preferable, that is of a solid iece of pliable felt formed on a shaft. Tf first two forms'are used, means are provided for making the cylinder water tight either of at the ends and means are provided for Q erases with a saponaceou-s mixture, but if the felt roller is used it is only necessary to wet the cylinder before commencing the shave. Brackets F 3 and F one supporting each end ofithe roller F are, by means of the pivots F and F, removably secured to the down turned sides of the plate A. Springs F, F secured on the under side of the ribs in the plate A are adjacent to the upper ends of the brackets Ft, 1 andact on the upper ends of these brackets continuously. I it is desired to use the moistening roller it is left in the position as shown in Fig. 2, and the light springs F and F insure that the roller will remain in position slightly in advance of the razor blade but if the mois tening roller is not desired, it is only necessary to push down on the roller sufficiently to cause the upper ends of the brackets F F to pass through the axial center of their retaining means when the springs F, F will cause the roller to assume the position shown in dotted lines in Fig.

The remaining descriptio'. is drawn to the modifications shown invhigs. 3 and 5.

I have shown in Fig. 3 a structure whereinthe moistening means comprises a perforated comb or guard M arranged adjacent to the cuttin edge of the razor, a tube or a series of tu es M extending rearwardly therefrom and a fount M connected to the tubes and by them to the perforated comb.

The fount may be wholly or partly pliable or compressible and so arranged that a slight pressure of the thumb or finger of the operator will force a small portion of the liquid frontthe fount to the edge of the perforated comb there to be distributed evenly over the surface upon which the razor is soon toact "lt may be an advantage to increase the length of the spring, thus securing greater flexibility, l have shown in the modification, 5, a means for attaining this end. In this figure the downwardly extending outside edge of the ribs A are bent at right angles inwardly and upon the shoulders. thus formed 1 rest a bowed spring V. The

' spring in this figure is transverse to the spring in the other figures and although ll hayeashown both ends of the spring resting npoiii -shoulders formed in the frame, I do not deem it necessary to follow this construction as l have found in my experiments that if one end of the spring be periinanently secured to one side of the frame the spring can be shortened to just pass the center, or rather the space occupied by the Having carefully and fully described my invention, what I claim and desire to secure by Letters Patent is 1. In a safety razor, a plate having a guard formed on one edge and having its rear portion provided with slits, thereby forming a tongue, a cam carried by said plate, means on said cam in engagement with said tongue for holding said cam in operative position.

2. In a safety razor a plate having a guard formed on one edge, and having its rear portion provided with a plurality of slits, thereby forming tongues, a cam, means on said cam in engagement with said tongues for holding said cam in operative position.

3. In a safety razor, a plate, a guard formed integral with said plate, the center portion of said plate being depressed, means for supporting a blade upon the plate, the depressed portion of said plate being provided with a series of slits resulting in projecting tongues, and a cam in engagement with the outer end of said tongues and adapted to force the blade into operative relation with said plate.

4. A safety razor, having a plate, a guard, means for securing a razor blade upon said plate, and a moistener pivotally secured to said frame adjacent to and cpiiperating with the cutting edge of said blade, as specified 5. In a safety razor, a plate provided with.

brackets integral with said plate, a guard formed integral with said plate, means for holding a razor blade in operable position on said plate, a moistener supported by said brackets and cooperating with the cutting edge of the blade, and a spring secured to the under side of said plate and adjacent to said brackets and cooperating with said moistener, as specified 6. A safety razor having a plate the center portion of which is depressed, said depressed portion being provided with a screwthreaded hole for engagementwith a handle, means for supporting a blade upon the plate, a series of tongues formed in the depressed portion of said plate and projecting rearwardly, and a cam in engagement with the outer end of said ton es adapted to force the blade into operative relation with said plate,
