SAFETY Razon.

Application led May [21,

Safet Razors, of which the following is a speci cation.

`The object of my invention is to provide a safety razor whereby parts of the holder and the blade may 'be separated to enable ready cleaning of the parts, and may be restored to operative relation, without requiring said parts and blade to be detached from one another.

In the form of invention illustrated in the accompanying drawings I have shown a type of safety razor comprising a holder having a handle, a guard, a-blader and a backing member forl the blade to clamp the latter over the guard, with means to'temporarily support the blade and backing member spaced from the guard and from each other,

to permit ready washing and wiping of the parts, and 'their ready reassembling for use.-

My invention also comprises novel details of improvement that will be more fully here inafter set forth and then pointed out in the claims. v 1 `Reference is to be had tothe accompanying drawings forming part hereof, where- 111-- Fig. lis a partly sectional ,side view of my improved razor; Fi 2 is a plan view; Fig. 3 is an edg'e view; 1g. 4' is avertical section on

line

4, 4 in Fig. 3; Fig. 5 is avfragmentary detail view, and Fig. 6 is a section on

line

6, 6 in Fig. 5.

Similar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates a guard member or late having guard teeth 2 and provided wit a tubular' handle 3, whichrmay'be attached to the guard member in any suitable frictionally receiving. the end of theliandle. The blade is indicated at 5, shownA ofthe two-edge variety, adapted to be` clamped -upon member 1 with its cutting edges in shaving relation to the guard teeth, A backing plate or member 6 for the blade is adapted to clamp the latter 'on the guard member.

The backing 6 is shown providedfwith rod 7 td'pass'through a'fhole in the blade and manner, as by means of a hub 4 on member 1 1921. Serial No. 471,333.

with pins 8 to pass through spaced holes 5b in the blades. The rod 7 passes through a Central hole in member-l and into handle, and the pins 8 pass through holes 1. The

parts

1, 3, 6 and 7 compriseva vholder for the blade. The blade vis detachably secured to a slidable support 9, shown inthe 'form of a tube, adapted to enter and to be partly pulled out of the handle. -Rd 7 isfslidable withinbla'de support 9 and is longer than vthe latter. The outer end of support 9 is shown provided with an annular groove 9 to receive hole of the blade, and said end is split longitudinally in one or more places, as at 9, for the material to expand elas Atically within hole 5 to detachably retain the blade on said support. The outer end of support 9 is shown beveled or rounded at 9".- to readily enter hole 5l of the blade.-

Means are provided lto limit the outward movement of rod 7 and blade support 9 from the holder parts 1, 3.l 1 have showny lsupport- 9 provided with a longitudinal slot 9d and rod 7 with a longitudinal .groove 7a which register to receive a stop 10 on handle 3, shown in the vform of a screw or pin extending from the wall of the handle into its bore 3? to enter slot 9d and groove 7. The metal atthe bottom l ot said slot and Vgroove engages stop l0 to limit the outward sliding of rod 7 and supporting tube 9, and said stop also serves to resist rotation of said rod and tube within the handle. The relative proportions of rod 7 and support 9 are such that when they are pulled out of the handle to theirlimit thc blade will be spaced between the l"guard member 1 and the backing 6 (Fig. 4).

Rod 7 is shown pro-vided with a projection or shoulder 7c to engage support 9-to push the latter outwardly with the blade.

Any suitable means ma be provided to retainrrod 7 to Vpress'on lade 5 to clampv the latter onl guard member 1. I have .shown a nut 11 to screw on the inner thread- 'ed end 7d of `rod 7 when the parts are assembled for use, (Fig. v1). Said nut is shown provided with a hub 11 having an annular groove 1-1b to receive a retaining spring `member 12 in handle 3. Member 12 -is shown in the form of"a split wire ring received in a recess 13 in thewall of the handle and projecting inwardly `suiiciently to rotatively retain nut l1 .onthe handle The spring ring member l2 will expand to there retained.

permit hub 11a to be pushed into and removed from said member.

1Vhen the parts are assembled, as illustrated, a blade may be applied .by unscrewing backing 6 from rod 7 at the threads lei, when the rod has been pulled-out, (Fig. l), placing a blade 5 upon the rod, re-attaching backing (3 to the rod, and pushing said backing toward the guard, the rod sliding in the handle, the blade being held toreceive the.

p pins 8, the backing pushing the blade to the guard. The nut ll1 will be screwed on the end 7d of rod 7. whereby the backing and blade will be clamped on the guard member. lVhen the backing is thus clamped Iupon the blade it will force the blade, at its hole 5, upon the end of support 7 to be Adjustment of the blade edge to the guard teeth may be made by operating nut il to press the backing more or less against' the thin HeXible blade, in a manner well known with safety razors of the variety referred to. When it is desired to clean the razor the nut is unscrewed from rod 7, the backing 6 and rod 7 are pulled outwardly and with them the support 9 is advanced to raise the blade from the guard,

such as illustrated in Fig. fl, the blade re' lnainlngfixed on said support. With the parts in such position, vretained collected but spaced apart, the blade and other parts are free and exposed to be washed and wiped,

overcoming the objection to separately l1an.

dling razor blades for cleaning purposes, and reducing the liability,7 of cutting the iingersof the user. 'After cleaning the parts it is merely necessary to push the backing toward the guard to restore the blade against the latter and screw the nut upon rod 7, the latter and support 9 sliding Within the handle. When it is desired to renew a blade the backing 6 ,is .pulled out, causing rod 7 to push out support 9 and the attached blade, the backing is'unscrewed from the rod, and the blade removed, a new blade is placed upon the rod, the backing is screwed back upon the rod, and the said parts are pushed toward the guard, and the nut is screwed on the rod, as previously described.

The advantage of being able to clean the parts of the razor Without requiring the blade to be removed from theA holder and replaced will be apparent, the only time lthe lblade need be manipulated being when're. newin it. v p

My invention is not limited to the details of construction set forth, as the same may be varied, within the scope of the appended claims, without departing from the spirit of my invention.
