SAFETY-RAZOR.

Specification of Letters Patent.

Patented Sept. 21, 1920.

Application filed March 22, 1920. Serial No. 367,662.

To all whom it may concern:

Be it known that I, SETH G. MAPBY, a citizen of the United States, residing at Derby, county of New Haven, State of With the above and other objects in view,

the invention consists of the combination and arrangement of parts as now tobe' fully described and hereinafter specifically claimed.

In the accompanying drawing forming a part of this specification,

Figure 1 is a side elevation of the improved safety razor, showing the blade resting on the blade support;

Fig. 2 a longitudinal section, showlng the blade adjustedto its farthest position from the blade support;

Fig. 3 a perspective view, partly in section, of'the adjusting screw of the invention' Fig.4 a perspective view of the adjusting pin of the invention; and

Fig. 5 is a perspective view of the set screw of the invention.

10 denotes. the shank or hollow handle, 11 the blade support and 12 the clampmg member of the safety razor of the invention. These parts are not new, and, therefore, need but brief description to better explain the features which I have invented. The blade support is" provided with a threaded opening 13 and the threaded outer end of the hollow handle is removably connected therewith. The clamping member has a frictional engaging portion 14: and an upright portion.l5, said upright portion being provided with an extension 16 hav1ng therein an'opening 17, larger than the outer portion of the handle, through wh1ch sa d handle passes, as shown. ;Extens1on 16 is provided with a lug 26,wh1 ch bears against an inwardly extending portion 27, shaped as shown, on the blade support. The blade support and clamping member have connection wlth each other as shown at 18 in Fig. 1, the connection preferably being by means of bayonet slots inthe inner edge of the blade support and fingers on the clamping member. serted between the blade support and the frictional engaging portion of the clamping member. To insert or remove the blade, the handle is grasped'and the upright portion of the clamping member is pressed toward said handle, the result being that the frictional engaging portion is forced away from the blade support, as will be readily understood. When'now the upright portion is released, the blade support and the frict1onal engaging portion of the clamping member are pressed toward each other, by reason of the bayonet interlocking means between these parts, andthe bearing contact between lug 26 and inwardly extending,

portion 27, to a suflicient extent to grip the blade and hold it, as disclosed in Fig. 1.

20 denotes an adjusting pin having a head 21, 22 denotes an adjustlng screw having a hollow head 23 to accommodate the head of the adjusting pin and a set screw 24, the adjusting screw being also provided with a longitudinal opening of smaller size, denoted by 25, through which the adjusting pin is adapted to loosely pass.

As will be apparent from Figs-1 and 2, the razor blade is adjustable from and toward the blade support by means of the adj usting screw. It is essential that the maximum adjustment of the blade be fixed and determined, that is, the blade should not be capable of adjustment from the support a distance greaterthan a predetermined dis tance, this predetermined distance being the maximum adjustment to whichthe razor should be capable of being set for use. And further, when the blade is adjusted its farthest distance'from the blade support, the

head of the adjusting screw should rest 19 denotes a razor blade in-' NUFACTURIBNG COM- No. 1,288,045), h reinbefore referred to, and an adjusting pin which has a drive fit into an adjusting screw of the nature of the one disclosed in the present application, but the adjusting pins heretofore known have been; diflicult to manufacture, that is, in the manufacture of structure for adjusting the blades of razors of the present type-it has been necessary to maintain an almost impossible. perfection in the manufacture of the parts, it having heretofore been necessary to construct an adjusting pin of an exact andaccurate predetermined length to screwed into the hollow handle until its head rests against the inner end of said handle, as it is shown in Fig, 2, the ad usting, pin may then be inserted 1nto the ad justing' screw until its outer end. restsagainst the blade, oragainst the frictional engaging portion ofthe clamping member, and its head lies in the hollow head of the adjustingscrew but away from the lower wall thereof, and the Set screw may then be screwed into said' hollow head until the outer end of the adjusting pin has raised the blade a predetermined distance. from the blade support, or the adjusting pin may be first inserted into the adjusting-screw, the setscrewthen loosely set in the hollow head, the adjustingscrew then screwed into the handle until its head rests against the inner end ofsaid handle, and theset screw may then be screwed into the hollow head to raise the blade as before. If desired, the set screw may be coated with shellac, or other similar substanee, before it is screwed into the hollow head, to make certain that it will remain in the position to which it is inserted... It will benoted that the. set screw may be. inserted any desired distance into the hollow head, but it may be added that the head of the adjusting pin shouldbe loosely arranged in the hollowhead so that when the adjusting screw is turned to adjust the blade, the adjusting pin will have no turning movement. This is. an advantage notv found in adjusting meansof this character heretofore known, such previously' known adjusting means forcing the adjustingpinto turn to exert a twisting actioinon the blade, thereby forcing the blade f-roinitsproper position between the blade support and the frictional engaging portion of the clamping member. The adjustin means hereinbefore fully described forces the outer end of the adjusting pin against the under side of the blade without imparting thereto a rotary thrust.

it will be apparent that the present invention. affords a very simple and accurate means for adjusting the blades of safety razors of the present or similar type.

What I claim is:

1; In a safety razor, a hollow handle, an adjusting screw disposed therein and provided with'a hollow head, an adjusting pin carried by said adjusting screw and extending into said hollow handle and having a head disposed in said hollow head, and a set screw disposed insaid hollow. head and adapted to bear against said head of said adjusting pin.

2. in a safety razor, .a hollow handle, an adjustingscrew disposed therein and provided with a hollow head, an adjusting pin carried by said adjusting screw and extending into said hollow handle andagainst a blade carried by said razor, saidfadjusting pin havinga head disposedin said hollow head of said adjusting screw, and aset screw disposed in said hollow head and adapted tobear against the head of said adjusting pin,v whereby they adj usting. pin may; begiven longitudinal reciprocation to adjust said bladeinsaid razor.

'7. A safety razor, including a hollow handle, means for holding a blade thereto, an adjusting pin disposed in said hollow handle and adapted to have longitudinal movement only when actuated to adjust said blade, an adjusting screw, through which said adjusting pinpasses, disposed in said hollow handle and provided with a hollow head, and a set screw disposed in said hollow head of said adjusting screw, whereby said set screw may be forced against said adjusting pin to adjust said blade in said razor.

In testimony whereof I aflix my signature.
