SAFETY RAZOR Filed Nov. 16, 1929 VPatented Feb. V1c, 1931 UNITED-,STATES PATENT OFFICE 'f BnAnDocK TAYIoIa or cHIcAGo, ILLINOIS w SAFETY RAZOR Application led November'lG, 1929.l Serial N o. 407,622(

Thefinvention relates to safety razors, Aand more particularly to a device of this class comprising ablade carrier adapted to have a removable blade mounted thereon, a blade 5 clamping member removably associated with v the carrier and serving to secure the blade in place, and a guard for the blade, the guard performing no function in holding the blade.

The main object of the invention is to pro- 'l vide a safety razor of the character described,

Another object of the invention is to pro-Y Q vide a safety razor'of the character described,

the blade of Whichmay be removably secured in position on the razor handle by means of a novel and improved clamping member, said clamping member being so constructed that both edges of lthe blade may be honed or Vstropped without any adjustment or changing Vof the parts other than the removal of the guard.

A further object of the invention is to provide a safety razor of the character described whichwill simulate as closely as possible, the

effect and Inode of manipulation, both in shaving and stropping, of a straight blade integral shank razor, and which shall, at the same time, embody the feature of having a double edge so that it may be used aeither right-handed or left-handed 'without change ing the position of the guard, and in which lthe guard performs no function in holding the blade. v f Y Ay still further object of the invention is to provide a simple, strong and'durable safety razor by means of which the operation of vshaving can-'be expeditiously and comfortably executed, inwhich the parts are releasably associated so that the device can be readily assembled and disassembled, which may be employed with a handle suchV as customarily associated with the ordinary razor,

and which may be stropped or honed without 59 the use of special appliances or attachments,

and while in operativev position on said handle. With the foregoing and other objects in view, which will appear'as the description proceeds, `the invention consists Vien-.certain novel and improved features of construction, arrangements,v and.v combination of parts, hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out inthe appendedclaims, it being understood that various `changes in the form, andpminor detailsof the structure i' be made withoutl departing from thespirit or sacrificing any of theadvantagesof the invention. e

Y tated generally, the invention comprises a bladev holder consistingY of two counter-part members, between which the blade is rigidly clampedwith its cutting edges protruding on opposite sides of the holder in position'not only-'for shaving with'either edge, at will, but also to expose both faces of the blade adjacent to each edge in position for stropping. A guard of the usual toothed or serrated form is provided forureleasable attachment with 7 l the holder, said guard fitting neatly upon the holder in guarding relation to both edges of the blade, but does not perform any function in holding the blade, thus when the guard isv removed the said device `may bemanipulated both in the operationv ofshaving and stropping, the same as arstraight-blade integral lshank razor.

vFor the purpose-of facilitating'anunderstanding of my invention, I have illustrated lin the accompanying drawings aperfected embodiment thereof, from an vinspection of which, when considered in connection with the following description, my invention, its. l

mode of construction, assembly, and many of and appreciated.

ts advantages` should be readily understood 'I Referring to the drawings, in which simi- Y lar characters of reference are employed'to indicate corresponding or similar parts throughout the several figures in the drawings Y 'Fig. 1 is a top plan view of an embodiment Y of my invention, illustrating the device fully assembled positlon-g F ig. 2 is a bottom plan view of the same;

Fig. 3, is a cross sectional view of the same taken on line 3 3 of Fig. 1;

Fig. 4 is a view in perspective of the blade clamping meinoer with the blade shown thereon in dottedlines;

Fig. 5, is alview in perspective of the body of the blade carrier and l Fig. 6, is a view in perspective of the guard member.

Referring more particularly tothe draw-J ings, the reference character 10, designates a blade carrier, which may be of suitable widtl and terminates at one end in a shank 11, which is pivotally mounted by means of the rivet 12, or the like, between the sides 13, of a handle. As clearly shown in Fig. 5, of the drawings, one side of the blade carrier is substantially flat, and isadapted to receive thereagainst the faceof the blade, whereas, the back face of said carrier may be slightly concave. The carrier 10, is provided intermediate the ends rthereof with pair of spaced openings, 141, and 15, said openings being substantially rectangular. A portion of the concave face of the carrier 10, adjacent each opening is cut away Ato forni` the rincer cutor countersunlr ledgesl, and 17, each of which .ledges has formed therein a small depression .18, substantially` in the central 4portion thereof. The construction of the blade carrier so far described is the same t "t disclosed in Patent No. 1,007,898, dated November 7, 1911, to T; C. Sheehan, and per seA forms no part ofthe present iii ntion.

A blade 19, having a longitudinal slot'20, therein, is adapted to be positioned on the Y dat surface of the blade carrier 10, said slot 20, being of siimcient length to permit the passage therethrough when .the blade is in operative position 'on the carrier, of a pair of resilient odset lugs 21, and22, provided on a blade clamping member 23, `which membei' is of substantially the same width as the blade carrier 10. The

lugs

21, and 22, are adapted when in operative position on the blade carrier, to frictionally engageV the

ledges

16, and 17, respectively, for clamping the blade l9,securely betweenthe said meiA bers. Y rThe underside of each of the lugs is provided with a projection 24, which is adapted forengagement within its cooperating indentation18, provided in the ledges, wherebydisplacement lof lthe

members

10, and 23, is prevented.'Y l. iA

The-resiliency of theoifset lugs causes a firm lockingengagement of the blade carrier and. blade clamping member, width the blade Y therebetween, and when so locked the edges of yand may if so desirechbe used .as a simple razor without a safety guard-' ,Y

- able guard 25, is added to the assembly of the parts previously described. The guard 25, is adapted for quick and ready attachment to the blade carrier 10, which blade carrier may be readily modiliedin construction to adapt it for the attachment of the guard. yThe guard 25, is provided at its forward extremity with a hooked tongue 26, which is adapted when in operative positionon lthe blade carrier 1G, to engage within a cooperating groove r recess 27, formed in the Lipper side ofthe carrier 10, at the forward end thereof. At the rear extremity, the guard is provided with an oifet lug 28,\which is adapted to pass through a catch opening 29, similar vto the opening 14,*said opening 29, being provided in the shank portion 1,1, of the carrier, which portion is also provided on the rear face thereof, with a countersunlr ledge 30, immediately acent the opening 29, said ledge beine,- adapted for frictional engagement by the ofi'- set lug 28, which is of suflicient resiliency to securely lock the guard in placeonthe'carrier.

ln order to prevent thedisplacement ofthe guard, when the latter is in operative position on the carrier, I provide a depression 31, in the ledge 30,-which indentation is adapted for receiving therein the projection 32, provided on the underside of the oifset lug 28, said depression and projection-cooperatitng to preif'enttho displacement'of the guard member;

the blade, as clearly shown in Figiire'l, ofthe drawings. ln order that the guard 25, may

be readily removed from the carrier, it is provided ith an uptiirned thumb piece 34, against which pressure may be exerted to slide the guard forwardlyout of its engaging -posltlirough the catch opening 29.

lt 1s to be notedv that the guard of the Arazor is entirely an added member, and that it performs no function in therazor assembly other than that of a mere guard, the blade being f held entirely bythe carrier andthe clampingV member. The guard may thus :be removed and leave the blade firmly secured in position onthe blade carrier, and when in such position theblade of the razor vmay be stropped tion until the 'offset' lug 28, is permitted to pass 120 stropping appliance or honed without makingit necessary to .em-

ploy a special stropping handle or a special or attachment. In shaving, the guard may thus be readily removed and the blade convenientlystropped that such parts be stamped from metal because of manufacturing economy, and tosecure the requisite resiliency and durability of the parts.

It is believed that my invention, its mode of construction, and many of its advantages should be readily 'understood from the foregoing without further description, and should be also manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of Wide variation within the purview of my invention, as defined in the appended claims.
