SAFETY-RAZOR.

new and useful Improvements in Safety azors, of which the following is a specificaftion.

This invention relates to the special forms of razors known as safety razors, that are provided with a guard portion in the nature of teeth, or. a comb, adjacent the cutting edge; which devices are usually provided with a readily removable blade so that when dull it can be removed for sharpening or substituted by another blade.

One of the objects of the present invention is. to provide an improved device in which the blade can be very easily and quickly insorted and removed. This 18 accomplished by the simple operation of supporting the holder member in one hand and grasping the;

blade between two fingers of the other hand;

insertingone end portion of the blade urider-' neath an overhanging lip ortion, which portion is made resilient ont e holder to spring back by the ressure ut on the blade, when the other en of the b adeis pressed down on .the holder and inserted under a lip portion at 31.! the other end of the holder; whereupon the reaction of the resilient portion will lock the blade on the holderbetween the lip portions.

A further object of the invention is to provide means whereby when the blade is locked position its cutting edges will be different y positioned or removed from the respective cooperative guard portions. In the accompanying drawing represent ing an embodiment of my invention Figure 1 shows the, device in perspective. Fig. 2 is a side elevation. Fig. 3 1s a partial vertical section. Fig. 4 shows the holder member separate from the handle. Fig. 5 shows the blade; Figs. 6 tolO show separately the con struction of the handle and its securing .means, and Fig. 11 is a vertical longitudinal section through the holder with the intermediate portion removed.

The device shownas comprising'a holder, denoted generally by 12, a blade 13,

and a handle member 14. The holder member 12 is shown as comprising a trough shaped portion 15' having the end portions 1p and 17. The holder isprovided with

opposite guard portions

the end members are provided with inwardly extending lip portions, that engage the end portions of the blade 13 which is shown as provided with

cutting ed es

20 and 21 on two 0 posite sidesthereof. n the-construction il ustrated the end member 17 is provided with the lip portion removed at the ntermediate part, forming two

lip portions

23 and 24 extending inward, forming an intermediate space or recess 25.

Atthe ,other end of. the holder a similar two-part overhanging lip member is provided, which in the construction shown, is formed of a U-shaped spring 26 secured at its intermediate part at the lower portion of the end member 16, by rivets or other suitable means. The

cnd portions

27 and 28 of the spring lip member overhang the end member 16 and have a recess 29 between them. The object of these

recess portions

25 and 29 is to permit engagement of the blade at the middle portions of each end by the thumb and finger of the operator and the blade is preferably provided with

extensions

30 and 31 at the end portions of a size to snugly fit in the

recesses

25 and 29 respee tively, and -project therebeyond, as indicated in big. 1. When so formed the blade is grasped between thethumb and linger by these extensions, and the-end 31 is placed in the recess at 29 between the spring lip portions, with the other end of the blade resting on top of the lip portions 23 and 24-. The end portion of the blade on the opposite sides of the extension 31 is caused to engage beneath the overhanging portions of the spring lips, and then pressure is brought to bear endwise on the extension 30, whereby the blade engaging the spring lip will bend it outward, until the end of the blade adjacent the )rojeotion 30 passes beyond the'end of the

lips

23 and 24, whereupon a downward pressureis exerted on the extension 30, that will bring this extension to engage in the recess 25, and the end portions of the blade on each side will then be in position. to be passed underneath the

lip portions

23 and 24. The blade will be pressed underneath these lip portions by the resiliency of the spring lip portions at the other end that have been. flexed, and the blade will be thereby engaged by the

lips

23 and 24 at this end, and will still be held by the overhanging

spring lip portions

27 and 28 at the other ,end. Atthe same time the blade will be support ed on the properly with regard to the

guard portions

18 and 19 respectively. The blade is prevented from sidewise movement when pressure is brought to bear on the cutting edges in the actof shaving, by the engagement of the side walls of the projections 30 and 31', with the side walls of the

recess

25 and 29, that is, with the opposite sides of the four lip portions, which are arranged to snugly engage the blade projections and prevent any lateral movement thereof.

The

guard portions

18 and 19 are formed relative to the blade when so positioned, that one of the cutting edges, as the cutting edge 20, isofi set or spaced from its guard portion 18, a greater distance than the cutting edge 21 is spaced or offset from its cooperating guard 19. By this arrangement the necessity for adjustment of the blade relative to the guard portions is obviated, as one edge can be used for an ordinary shave, and the opposite edge can be employed for a closer shave. The blade and the holder being symmetrieally arranged, it is obvious that the bladecan be removed and turned end for end and again positioned, so that either edge can be brought to the position of ordinary or close adjustment as desired.

The handle 14 can be secured to the holder, in any suitable manner, and preferably is adjustably attached so that the angle of the cuttin edge relative to the handle can be varied as ('esired. In the form illustrated the handle is shown as adjustable in any position be:

tween certainangular limits,- in a plane perpendieular to the cutting edges of the blade. The trou l1 portion 15 of the holder is provided wit a slot 32 at its middle portion that extends transversely to the guard portions. The handle member 14 is provided with a threaded member that screws into a nut member carried in the trough and is slidable in the opening. The nut member is permanently attached to the trough member and the handle member can.be screwed into and removed. from the nut member. When screwed up tight the handle member locked in position, but to adjust the-handle member it is only necessary to loosen it, then swing the handle and connected nut member to the desired angle, and then screw the handle u tight again. In the construction illustrate the tubular handle member 33 has a screw portion 34 permanently connected therewith,thatcomprises a screw 35 and a sleeve 36. The nut member as shown com rises an apex:- tured curved block 37 having tlie convex side curved. to fit the bottom of the trough ertion 15; a collar 38 having a face 29 curved to engage the outer side of the trough member 15 and an internally threaded sleeve 40 having a flange 41. The sleeve is passed the block 37 by flaring its end portion.

through collar 38 and its llange loosely engages a shoulder 42 therein. T he sleeve is assed through the opening 32 and loched in The collar 38 is loosely carried on the outer llange portion of the sleeve, whereby it is freely movable in the opening 32, yet cannot be removed from the holder. The handle member is attached by its screw 35 being screwed into the threadedbore of the sleeve 40, and when screwed up tight the end of the screw portion 34 will engage the collar 38 loosely carried by the sleeve 40, and ea use this collar to be pressed between the screw portion 34 and the trough member 15, whereby the bandle is securely locked in position.

From this construction it will be seen that the lather and hair not only can readily pass through the guard )ortion, but between the guard portion and the blade, trough ortionof theholder. And such Ina-ts ter can ereadilyremoved therefrom by holding it under a spigot or passing it through w ater that will pass in one side through the guard portion and force the lather and hair out the opposite side. Hence there is no possibility of the lather and hair clogging the blade. .l t will also be seen that there are no cavities to collect the lather and which would be dillieult to clean. By removal of the blade every part .is readily accessible, and can be at once cleaned by the application of water. The

directly into the only movable part for securing the blade is the spring lip, and this is normally held adjacent the end member of the trough. Furthermore, the device is very simple and economical of construction, consisting practically of the trough member comprising a. curved plate with two end plates rigidly secured thereto, one of these having overhanging lip portions at opposite sides and a spring lip that is a single member permanently secured on the outside of one of the end members, for engaging the blade. The blade for use in this razor does not require any opening therein, but is a rectangular member with a projection or ear at the middle portion of .each end.
