SAFETY RAZOR.

Application filed December 15, 1925. Serial No. 75,588.

This invention relates to safety razors and pertains to an improvement in the construction of both the blade and holder.

One of the main objects of the present invention is to provide a holder member which greatly facilitates the manipulation of the razor during the shaving operation, to prevent slipping or turning of the blade to a dangerous angle, and which augments the proper relative position of the blade with respect to the face.

The invention further comprehends a safety razor blade and holder which facilitates'the application of the blade to and the removal of the same from the holder.

The invention furthermore contemplates effectual co-operating means on the blade and holder for insuring the proper relation of the cutting edge of the blade to the guard teeth of the holder andwhich positively precludes accidental displacement of the blade during the shavingoperation.

As a still further object the invention re sides in an improvementin the construction of the blade rest, the formation of which prevents clogging and allows for the flushing away of the lather and particles of the beard.

The invention also comprehends a safety razor construction which is extremely simple, inexpensive and eflicient.

With the above recited and other objects in View, reference is had to the following.

specification and accompanying drawings in which there is exhibited one example or embodiment of the invention which isin no way intended as a limitation upon the scope of the appended claims as it is to be clearly understood that variations and modifications which properly fall within the scope of said claims may be resorted to when found expedient.

In the drawings- Figure 1 is a perspective view of the razor illustrating the blade and holder in assembled relation;

Fig. 2 is a planview thereof with the blade applied;

Fig. 3 is a fragmentary sectional view taken approximately on the line S-+3 of Fig. 2; g

Fig. 4 is a fragmentary plan view of the holder with the blade removed;

Fig. 5 is a plan View of the blade.

Referring to the drawings by characters of reference, the holder includes a substan tially fiat relatively wide handlc portion 10 formed at one end with a trai'isversely curved blade-supporting portion or rest 11 disposed at an obtuse angle with respect to the handle and formed at its free forward edge with downwardly curved guard teeth 12. The blade-supporting portion 1.1 is fur-' theiprovided at the forward corners thereof with a pair of front hooked and side upstanding abutment lugs 13 and 14, the latter being spaced apart approximately a distance equal to the length of the blade and the inner faces of the former lugs 13 being disposed substantially in almement with the medial portion of the guard teeth 12; The.

body of the blade-supporting portion or rest 11 is medially cut away as at 15 and is formed in its rear edges at opposite sidesof the handle 10, with notches or recesses 16. Resilient blade-engaging and retaining arms 1'? are secured to the opposite side edges of the handle and are formed with angularly disposed, hooked terminals 18, which proupper face of the blade rest or supporting portion 11. the inherent resiliency or springiness of the arms 17 tending normally to effect lateral movement of the arms and hooked terminals in a given direction ect through the notches 16 to overlie the toward one of the end walls of the notches or recesses 16.

The blade 19 constituting a feature of the present invention and especially designed for use in connection 'with the holder hereinbefore described, consists of a flat piece of material of generally oblong shape, having a forward cutting edge 20 and formed in the opposite rear edge with laterally spaced notches or recesses 21, the inner walls 22 of which are'inclined with respect to the the blade from the holder, while the edges of the arms adjacent the terminals 18 cooperate with the inclined inner walls 22 of the notches 21 to set up a camming action for forcing or urging the blade 19 forwardly with its front cutting edge in frictional contact with and under the front hooked lugs 13. In removing the blade from the holder, the operation is reversed.

In use, the opposite fiat faces of the handle are grasped between the thumb and fingers, as illustrated in Fig. 1. The relatively wide flat handle 10 greatly facilitates the holding of and proper manipulation of the razor during the shaving operation and positively precludes any chance of accidental turning of the blade and blade-supporting portion with respect to the handle as has often been found to be the ease in safety razors having the usual round handle. The curved bladesupporting portion or rest 11 a li'ords a ready outlet for the severed beard and lather. and permits of the flushing and cleansing of the razor during the shaving o eration.

The simplicity of construction as well as the facility with which the razor may be handled, are deemed to be innportant feitures of the invention and are thought to be readily apparent from the drawin s when taken in connection with the foregoing specification.

eague ing laterally spaced notches in its rear-edge,

and a holder therefor, said holder comprismg a flat, wide handle portion and a trans- :versely curved blade-supporting portion disposed at an obtuse angle from the free end" of the handle, guard teeth formed at the free forward edge of theblade-supporting portion, a pair of upstanding front hooked and side abutment lugs at the free corners of the blade-supporting portions, and resil lent blade-engaging and retaining arms secured to toe opposite side edges of the handle having hooked terminals engaging with the notched rear edge of the blade, the

inner wall of the notches being inclined with V respect to the rear edge of the blade for rngagement by the arms to effect impingement of the forward. cutting edge of the blade against and under the front abutment lugs.
