SAFETY-RAZOR;

I Application filed February 21, 1914. serial No. 220,242.

To all whom it may concern Be it known that l, JOSIAH PERCIVAL STE- VENS, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to improve-- ments in safety razors, and it is intended to provide a cheap and simple form of safety razor in which the razor blade is firmly held in place when desired, and in which the parts are readily assembled and disassembled for the purposes of cleaning, renewal, or the like. i

It is well known that with the safety razors now generally in use, there is more or less annoyance in taking the razor apart and cleaning up the same, and restoring the parts to the assembled position each time the razor is usedyand the object of my present invention is to simplify and reduce the number of these parts, and to facilitate the operation of assembling and disassembling the same, as will be hereinafter described and claimed.

Reference is had to the accompanying drawings, in which Figure l is a plan view of the safety razor with the parts assembled and ready for use; Fig. 2 shows an inverted plan of the device, with the parts as shown in Fig. 1; Fig. 3 shows the razor blade in position, and the resilient clamp swung away therefrom; Fig. 4: shows the parts in the position of Fig. 3, 'exceptthat the razor blade has been removed from its support; and Fig. 5.

shows a section through the support, razor blade, and resilient clamp, along the line 5-5 of Fig. 1, and looking in the direction of the arrows.

A represents the rigid supporting piece, or support, on which the razor blade is mounted when in use. This support is provided with the usual guard teeth a, and is )rovide'd with any suitable means for bold-- ing the razor blade in place, such, for instance, as the lugs a. Oh the opposite side,

near its outer end, the support is provided with the stud a to engage the fork in the resilient clamp, as will be hereinafter described.

The outer end of the support is preferably curved slightly, as at a and this support is provided with a flattened portion a. and an inclined face a near the handle B. This handle is pivoted to the blade, as at Z); The stud O is secured to the flattened portion a of the razor support, and has its shank c projecting down through the slot 6 in the resilient clamp E, the rear end of which clamp is provided with a'thumb lug e. The front end of this clamp is bent over, as at 6 to engage the front end of the razor support, and this bent-over portion 6 is provided with beveled jaws e terminating in the holding notche adapted to engage the stud a on the razor support when the clamp is in the locked position shown in Figs. 1

and 2.

To assemble the parts, swing the clamp E clear of the support, as shown in Fig. 4, apply the razor blade, as shown in Fig. 3, then swing the clamp until the jaws c are in line with the axis of the razor blade, at the same time moving the clamp forward longitudinally relative to the stud C, so as to permit it to pass freely over the end a of the support A, and then slide the clamp backward until the stud a guided by the beveled jaws a, enters the slot (-1 These jaws will bind the clamp in place against longitudinal displacement, and the razor may be used as in the ordinary way. To dis-assemble the parts, press the thumb lug e outward, causing the stud a to disengage from the notch 0 and clear the jaws c, then swing the clamp to the position shown in Fig. 3 and remove the razor blade. It will thus he noted that the clamp E is locked and unlocked by a sliding motion, and held permanently attached to the razor support, but at the same time readily accessible for the purpose of cleaning; thus the only rcniovable part is the razor blade.

While I have shown the razor blade slotted, as at (I, and attached to the support by lugs a in the usual way, it will be obvious that the razor blade may be connected to the support in any convenient way, and clamped in place by the improved resilient clamp herein dcscribci'l. it will also be obvious that various other changes might be made in the construction, cmnbinut-ion and urrangement of parts which could be used without departing from the spirit of my inrearWardly-projecting arm, means for detachably connecting said blade to the support, and a resilient clamp engaging the outer end of said arm and having a slot en gaging said pin, said clamp being adapted to swing lateral-1y about said pin and to slide longitudinally thereon, thus to release the razor blade when desired and to lock the said razor blade on said holder, substantially as described.

2. In a safety razor, the combination with a razor support provided with means for attaching the razor blade to one side thereof, a headed stud connected to said support on the same side With said razor-holding means, a'lug provided on the opposite side near the outer end thereof, and a resilient clamp slotted longitudinally to engage said stud and bent over at its outer end, and promeans, a lug provided on the opposite side near the outer edge thereof, a resilient clamp slotted longitudinally to engage said stud and bent over at its outer end, and provided with jaws to engage said lug, and a thumb lug provided on the inner end of said clamp in rear of said slot, the said resilient clamp being adapted to lock saidrazor blade in place and to release same when desired, substantially as described.

In testimony whereof, I aliix my signature, in presence of two Witnesses.
