Y Claims.

This invention relates to the class of razors and pertains particularly to an improved form of safety razor of simplified construction.

The primary object of the present invention is to provide a safety razor adapted to use the usual single edgetype of blade. which is of a design permitting its formation or stamping from a single body of material whereby it will be in its completed form of unitary construction, that is, devoid of separable or removable parts.

Another object of the invention is to provide an improved safety razor structure wherein the separation of two guard members between which a blade is mounted, is eifected simply by the compressing of the handle of the razor to effect the flexing of one of two portions thereof, release of the flexed portion permitting the guards to move back to blade gripping position under the inherent resilient action of the said flexed portion.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strictconformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

Figure 1 is. a view in topplan of a razor constructed in accordance with the present invention.

Figure 2 is a view taken partly in side elevation and partly in central longitudinal section through the razor.

Figure 3 is a view in elevation of the head end of the razor.

Figure 4 is a view in plan of a metallic blank stamped out for the formation of the razor.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the razor constituting the present invention is indicated as a whole by the numeral l and comprises, as more clearly shown in Figure 2, the two handle portions 2 and 3 which lie one over the other. These two handle portions are integrally joined at one end of the razor handle, as indicated at 4, while at the other end each has a guard plate integral therewith, the plate of the handle portion 2 being indicated by the numeral 5, while the other plate, which is carried by the handle portion 3, is indicated by the numeral 6. These plates may be referred to respectively as shield and guard plates, the shield plate covering the major portion of the outer face of a safety razor blade inserted between the plates,

as indicated at I, while the guard plate completely covers the inner face of this blade and extends below the lower or cutting edge of the same, as 5 shown.

The razor is formed or stamped from a single body of metal having the required characteristics, the blank, before being bent to form the razor as illustrated in Figures 1 and 2, appearing as shown in Figure 4, where it is ifldicated generally by the numeral 8.

As illustrated, the portion 2 of the handle is bent transversely intermediate its ends, as indicated by the numeral 9, whereas the under porlion 3 of the razor handle is straight and the plates 5 and 6 are bent back toward their respective handle portions until they lie in planes oblique thereto so, that the acute angle formed between the plate 6 and its handle portion 3 positions in the acute angle formed between the plate 5 and its handle portion 2, when the razor is assembled and the plates 5 and 6 lie in parallel planes. With the plates in these planes, it will be seen that the upper handle portion 2 is spaced away from 5 the portion 3 at the central partof the handle and it will be apparent that since the material is of a resilient character, a pressure exerted against the under side of the handle portion 3 will flex the latter or will create a common flexing of the two handle portions tending to move them together at the central parts and, therefore, tending to separate the plates 5 and 6. This will permit the insertion of the razor blade, which is indicated by the numeral 1. The free transverse edge portion of' the inner or guard plate Sprojects a substantial distance beyond the free transverse edge of the shield plate 5 and a portion of the plate 6 adjacent the free edge is bent inwardly out of the planes of the two plates, as indicated 40 at Ill, and immediately above this bent orangle portion IU of the guard plate the latter is provided with the slot ll, before which the cutting edge of the blade 1 lies. It will thusbe readily apparent that in the use of the razor, the opening ll permits lather and cut hair to pass over the cutting edge of the blade so that this matter will not clog up the razor.

In practice it is preferred that theblade I be provided with a central slot extending, prefo erably, transversely thereof, as indicated at l2, and that the guard plate 6 be provided with the forwardly pressed cusp l3 WhlChiiS adapted to engage in the aperture of the blade so as to assist in retaining the blade in position and also serve to center the blade with respect to the guard plates. The forward -or shield plate may have an aperture l4 formed therethrough in line with the cusp l3 which will permit the user of the razor to see at once when the cusp is engaged in the slot or aperture in the razor blade.

From the foregoing it will be readily apparent that a razor constructed in accordance with the present invention will be economical both to produce and to retail and will give satisfactory service as the blade will be firmly held in the at its bent portion away from the other part whereby to urge said plates together.

'2. A razor comprising a handle portion and a blade holding portion formed integrally there-.

with and the whole being shaped from a single piece of material, the said handle portion constituting two elongated. parts lying one over the other and connected together at one end of the handle, the blade holding portion constituting 7 two plates each carried at a free end of a handle part and' forming an acute angle-therewith, the two plates lying in relatively. close parallel planes, and'the two handle parts being normally resiliently urged apart whereby to effect the movement of the plates together into blade holding position.

3, A razor comprising a handle and a razor blade holding portion, the handle portion being in two elongated parts joined together at one end, said head portion comprising two plates each forming an integral part of a handle at the free end of the latter and forming an acute angle therewith, one 1am handle parts being straight throughout and the other handle partbeing bent 5 v end, said head portion comprising two plates each forming an integral part of a handle at the free end of the latter and forming an acute angle therewith, one of said handle parts being straight throughout and the other handle part being bent transversely intermediate its ends and spacedzo away from the straight part, the angle formed between the straight partof the handle and the plate thereof lying within the angle formed between the other handle part and plate, the said plates being normally in parallel planes, the said plate ofv the straight handle part having the edge lying transversely of the handle extended beyond the transverse edge of the 1 other plate and provided with a slot extendin transversely of the handle. I 1 5. A razor, comprising a'handle portionand a blade holding portion in which the handle portion constitutes two elongated members arranged in side by side relation and permanently joined at one end and the blade holding portion I constitutes two plates each carried by a handle member, one of said handle members being bent transversely and normally resiliently tending to move at its bent portion away from the other member whereby to urge said blades together.
