To all whom it may concern:

Be it known that I, John Heissenberger, a citizen of the United States, and a resident of the borough of the Bronx, of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

One object of this invention is to provide a safety razor in which the Blade is easily attachable and detachable and while attached is retained upon the razor base or holder in a simple manner, the construction requiring very few parts and being considerably simplified.

The improvements will be more fully explained in connection with the accompanying drawings in which,

Figure 1 is a view in side elevation of the improved razor. Fig. 2 is a view in front elevation, with the handle indicated as being inserted in one end of the base or holder. Fig. 3 is a view in rear elevation with the handle indicated as being secured in the other end of the base or holder. Fig. 4 is a sectional view on a plane indicated by the line 4—4 in Fig. 3, and, Fig. 5 is a detail view showing a slight modification.

The blade a, which in the present case is illustrated as of the ordinary wedge-shaped form, is held in a base, holder or frame b which is provided with the usual guard c and with retaining means for the blade which constitute one of the features of the invention. These holding means include forward lugs d, preferably at the ends of the guard, end lugs e one at each end of the blade, and a single resilient finger f for the top of the blade. This finger is pivoted upon the rear side of the guard (Fig. 3) and extends down over the front face of the blade with its end bearing substantially upon the middle of the blade. In this way the blade is held from forward and endwise movement by the lugs d and e, and it is held flatwise upon the base and against backward or upward movement by means of the finger f. The finger f is preferably made springy in and of itself so that its forward end bears down yieldingly upon the front face of the blade, and the toe of this finger preferably bears against a spring finger g upon the rear side of the base, (Fig. 3) so that when it is moved into position upon the blade, the spring g will hold it in such position with a yielding pressure. The finger f bearing as it does upon the center of the blade will readily hold the blade flatwise upon the base. This finger will also, as was stated above, serve to hold the blade in its forward position. Thus this single finger performs the functions which have generally been performed by two or three elements heretofore.

The handle h may be secured, as in Fig. 1 by screwing the same into a seat i upon the rear side of the base b or it may be secured in the base at either end of the blade in seats which are similar to the seat i. One of these end seats is indicated by the character k in Figs. 1 & 4. By this means, the razor may be adapted for use in the same manner as other safety razors having handles perpendicular to the blades, or it may be used as an ordinary razor with a safety guard. Where it is used in the manner of an ordinary razor, it will be obvious that it may be adapted to be operated with either the right or the left hand according as the handle is inserted in one end or the other end of the base (Figs. 2 and 3).

In Fig. 5 one of the lugs d is shown as overlapping the corner of the blade, whereas the lugs d in the other figures do not overlap the blade. It will be obvious that the lugs may be formed in any manner and that other changes may be made without departing from the spirit of the invention.

I claim as my invention:—

1. The combination in a safety razor, of a blade, a base therefor, and means to secure the blade to the base including a resilient finger adapted to bear yieldingly substantial upon the middle of the blade and bent back over the top of the blade and base whereby said finger holds the blade flatwise upon the base and against upward movement, means to pivot said finger upon the base whereby it may be moved to permit the insertion and withdrawal of the blade, and a spring to hold the finger normally in position for securing the blade to the base.

2. The combination in a safety razor, of a blade, a base therefor, and means to secure the blade to the base including a resilient finger adapted to bear yieldingly substantially upon the middle of the blade and bent back over the top of the blade and base whereby said finger holds the blade flatwise upon the base and against upward movement, means upon the underside of the base to pivot said finger thereto, and a spring upon the underside of the base coöperating with said finger to hold it normally in position for securing the blade upon the base.

3. The combination in a safety razor, of a blade, a base therefor, and means to secure the blade to be base including lugs to limit the forward and sidewise movements of the blade and a resilient finger adapted to bear substantially upon the middle of the blade and bent back over the top of the blade and base to hold the blade flatwise upon the base and limit its upward movement, means upon the underside of the base for pivoting said finger thereto, and a spring upon the underside of the base, said finger having a toe adapted to engage said spring, whereby said finger is normally held in position for securing the blade upon the base but may be moved against the action of said spring to permit the blade to be withdrawn.
