SAFETY-RAZOR.

Specification of Letters Patent.

Patented Aug. "Z, 191'?.

Application filed November 10, 1916. Serial No. 130,642.

To all whom t may concern Be it known that I, PETER BUSCEMI, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Safety-Razors, of whichthe following is a specification.

This invention relates to that class of devices known as safety razors and has for its principal object the provision of a blade holder which is constructed from a single piece of material slotted along its longitudinal edges to provide guards and bent adjacent to the guards into lips to receive the blades and lips to hold the same uniformly positioned relatively of the guards.

Another object of the invention is to provide a blade holder in which the blades will be securely held against accidental derangement when associated with the holder.

A still further object of the invention is to provide a retaining device forming a part of the holder and provided with adjustable means which can be brought to bear against the adjacent ends of the latter blades to hold the same in accurate cutting positions.

With the above and other objects in View which will appear as the nature of the in vention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described and particularly pointed out in the claim.

In the drawings Figure 1 is a side view of the device.

Fig. 2 is a plan view of one of the blades.

Fig. 3 is a transverse section on the line 3 3, of Fig. 1.

Fig. 4L is a section on the line 4 4 of Fig. l.

The device comprises a blade holder 1, which is preferably constructed from a single piece of sheet metal bent inward and folded upon itself at each side of its longitudinal center so as to produce walls of double thickness with rounded outer edges as seen in Fig. 3. rlhe inner leaf of each wall near the center of the sheet is then bent again outward into a lip 3, but the same is not folded down closely against the leaf, the bend being rather gentle and the tip ofthe lip deflected inward toward thea leaf as best seen in Fig. 3. Thus is produced a pocket at the inside of the wall of double thickness, the pocket constituting a blade holder in which the blade is free for longitudinal sliding movement. At the iuner end of each of said lips the metal is up` set against the adjacent leaf of the structure so as to form a stop i, which is designed to limit the sliding adjustment of the blade in one direction.

The lips terminate within the longitudinal edges of the holder, and beyond them the double walls of the holder are slitted to provide comb-like guards 6, against which the cutting edges of the blades may lie. Relatively narrow blades 7, are employed in combination with the holder just described and said blades are adapted to be inserted under the lips and moved in a longitudinal direction until their inner ends abut against the stops 4:. The outer ends protrude slightly beyond the adjacent end of the holder in order that a retaining device such as the nut 8, can be brought thereagainst and thereby hold the blades in confinement against said guards, 6. rlhe nut is removably mounted upon a short threaded stem 9, which extends from the main body of the holder l. By this simple expedient is produced from a single piece of sheet metal a double blade holder, each half of which includes a comb-link guard having teeth of two thicknesses and round.- ed at their outer ends, and a pocket composed of one wall of said guard and a resilient lip whose tip springs toward it so as to clamp the blade firmly therein. The longitudinal movement of the blade in this pocket brings one end up against the stop 4l when the nut 8 is adjusted against its other end, and therefore if the biting` action of the lip should not be sufficient to hold the blade in the pocket, the clamping action exerted longitudinally of the blade would surely hold it in place. A. holder of this class can be very cheaply manufactured from sheet metal by common and well known forms of machinery not necessary to specify in this instance, and the cost will be so small that il it should get out of order the user may well throw it away and purchase another. The blades when they become dull are also thrown away and others inserted.

The main body of the holder is extended into a shank 10, and the latter has pivotal connection at l1, with a handle 12, of any suitable well known design and into which the blade holder can be housed and the device folded into a relatively compact package when not in use.

What is Claimed as new is i" The herein described safety razor, the same comprising a pair of narrow blades, each sharpened along its outer edge; a blade holder made up of a single piece of sheet metal initially substantially rectangular, bent upon itself along each longitudinal edge and folded inward in two leaves, and each leail then bent again outward and rolled into a lip Whose tip bears yieldingly against said leaf, the outer rounded edges of said holder being slitted to produce comblike guards, and the inner ends of said lips being upset against the contiguous leaves to produce stops for the inner extremities of the blades, a threaded stem at the outer end of said holder, and a nut thereon to Contact with the outer extremities of the blades; and a handle for the holder.

In testimony whereof I, aliix my signature. Y
