"Specification of Letters Patent.

Patented 'Dec. 8, 11908.

Application-filed July 18, 1908. Serial No. 444:,221.

To all whom it may toncern: Be it known that I,- TERENCE F. Ormmnga citizen of the United States, and a resident of the city of New York, borough of Brooklyn,

in the county of Kings and Stateof New York, have invented a new Improvement in Safety-Razors, of which the following is a full, clear, and exact description.

The invention relates to safety razors having thin, flexible blades, and its object is to provide a new and improved safety razor, arranged to permit of conveniently placing the razor blade into accurate position on-the frame or holder relative tothe guard thereof, and to provide a back plate for giving the desired rigidity to the razor blade and which back .plate can be readily opened or closed and securely locked in place when in :a closed position.

'(llhe "invention consists of novel features an whic will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented .in the accompanying drawings forming a part of this 'SPBOlfiCfi/tlOIl, in which similar characters of reference indicate corre.

sponding parts in all the views.

Figure 1 is a perspective view of the improvement; Fig. 2 is an enlarged front elevation of the improvement, the razor blade being removed and the back plate being swung rearward; Fig. 3 is a cross section of the improvement; Fig. 4 is a rear elevation of the same, and Fig. 5 is a erspective view of the locking lever for the ack plate. Y

The razor-blade A, preferably formed of a thin, flexible piece of steel, is supported at its front and rear portions by front and rear members B and C of the frame or holder for the razor blade A. The front frame member B is provided with the usual guard D, operating in conjunction with the cutting edge of the razor blade A, and on the said front frame member B are formed the upwardly and rearwardly bent stops E for receiving the front corners of the razor blade A, to limit the forward movement of the said razor blade and to bring the cutting edge thereofinto pro er relation to the guard D. The front mem er B of the frame is also provided at its sides with upwardly-extending guide-lugs F, for engaging the side edges of the razor blade A,

Iparts and combinations of the same,

the form of a pocket in which the back of the razor blade can be inserted.

The front and rear members B and C of the frame or holder are provided with downwardly-extending arms B, 0?, riveted or otherwise secured to the 11 per ends of the shanks H, H of a hand e H, preferably made of spring metal bent into .U-shape, as shown in Fig. 3. The shanks H, H have a tendency to move towards each other, owing to the resiliency of the handle, so as to hold the razor blade A securely in position on the front and rear members B and C, it being understood that the retaining-means C tends to press the blade forwardly to firmly engage the latter with the stopsE.

In order to give the desired rigidity to :the

razor blade A, aback plate I is provided,

. by trunnionsC projecting sidewise from the rear members C of the frame or holder, so that the back plate I- can be sprung rearwardly into an open position, as shown in Fig. 2 and in dotted lines in Fig. 3, or forward into a closed position onto the top of the razor blade A at a point near the cutting edge of the blade and above the front member B of the frame, as plainly indicated in Figs. 1 and 3.

In order to firmly hold the front end of the back plate I in engagement with the razor blade A, and at the same time lock the back plate I in place, the following arrangement is made: A leverJ is fulcrumed on a bolt K held on a boss L attached to the rear of the depending arm C of the rear frame member C, and the lever J is adapted to engage the rear end of the back plate I at or near the middle thereof, and in the rear of the axis of the trunnions 0 so as to press the rear end of the plate I upward and consequently the front end of the plateI downwardly against the razor blade A. The lever J is provided with a suitable handle J and with a lug J adapted to snap into a recess L formed in the face of the boss L so as to hold the lever J in a locked position when engaging the back plate I (see Fig. 3 and dotted linesin Fig. 4).

When using the safety razor the several parts are in the position shown in Figs. 1 and 3, that is, therazor blade A is securel held in osition on the front and rear mem ers B an C, and the desired rigidity is given to the razor blade A by the back plate I locked in place by the lever J. When it is desired to wash the razor it is only necessary for the operator to swing.the lever J into an open position, as shown in Fig. 4, to release the the razor blade A from the retaining means C and the stops E. The screw K previously mentioned preferably extends through an opening in t e shank H to the front thereof, and on this front end of the bolt K is formed a head K, to prevent the handle shanks H, H from being pressed too far apart.

The safety razor shown and described is very simple and durable in construction, com osed of comparatively few parts, and not iable easily to get out of order.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A safety razor rovided with a frame for the razor blade, a ack plate mounted to swing onthe rear of the said frame and adapted to engage with its free end vthe razor blade adjacent to the cutting edge thereof, and a lever fulcrumed on the frame and ada ted to engage the rear end of the said back p ate for ressihg' the free front end of the back plate .into contact with the razor blade adjacent to the cutting" edge thereof.

2. Asafety ra'zor rovided with a frame for the razor blade, a ack plate mounted to swing on the rear of the said frame and adapted to engage with its free end the razor blade adjacent to the cutting edge thereof, a lever fulcrumed on the frame and ada' ted to engage the rear end of the said bac plate for pressing the free front end of the back plate into contact with the razor blade adjacent to the cutting edge thereof, and means on the said lever for looking it in a closed position.

3. A safety razor rovided with a frame for the razor blade, a ack plate mounted to swing on the rear of the said frame and adapted to engage with its free end the razor blade adjacent to the cutting edge thereof, a lever fulcrumed on the frame and ada ted to engage the rear end of the said bac pressing the free front end of t e back plate into contact with the razor blade adjacent to the cutting edge thereof, and a lug onthe lever adapted to engage a recess in the frame for locking the lever in a closed position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
