SAFETY-MZOR.

Letters Patent. Patented May 3, 1910.

Application filed MaNf, 1909. Serial No. 496,344.

To aZZ w7wm it may concern:

B'e 1t known that I, CHARLES F. SMITH, a c1t1zen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and'useful Improvements in Safety-Razors," of which the following 1s a specification.

My invention relates to improvements in safety razors, and the objects of my improvements are simplicity and economy in construction and convenience and efliciency in use.

In the accompanying drawings :-Fignre 1 is a longitudinal section of my razor. Fig. 2 is a plan view of the same. Fig. 3 is an end view of the same; .Fig. 4: is aside elevation of the stropping device to my.razor and a blade. Fig. 5 is an endrview "of the same. Fig. 6- is a perspective view of my guard piece and handle. Fi 7 is a perspective view of a blade and hlade back with the blade out about half way from the normal position.

.My safety razor is of the type provided with a removable blade and a stropping device for 'holdin the blade for convenlence in stropping, al as will be hereinafter described.

A is the guard piece to my razor and comprisesv a piece of sheet metal doubled back on itself longitudinally to form a tubular back '10, a guard wing 11 on the front side comprismg first a flat portion forming essenh tiall 1; d dl j ti fl e 12 j the bearing points for the front member be-' along the edge of the slot in the said tubu lar back 10, then abackwardly projecting upper bearing rib 13, below which the said guard Wing swells outward and again back and is provided at the lower end with'a closed combformation l4 comprising'a series of teeth 15, closed at the'outer edge by a bar 16, the said teeth beginning inter-- mediate the said swelled portion and curving backward to a point near the lower edge to form. an interrupted lower bearing rib 1.7, and then bending abruptly outward to the said bar 16 at the extreme edge,

The back member of my-guard piece A comprises a downwardly and forwardly pro ecting clamping wing 18, forming essentially a flange extending from the back side of the slot in the said tubular back 10, and has at the lower extremity the bearing edge 19 extending longitudinally intermediate thc sjaid upper bearing rib 13 and the hold the said blade B within the said in use.

said lower bearing rib 17. The ends and corners 28 of the said tubular back are cut away for facilitating the removal of the blade B and blade back C to be described, leaving a central portion 20, the resiliency of winch is adapted to hold the blade B when in position and in use.

The blade B comprisesaflat piece of steel of rectangular shape, provided along the center. of the back edge with a short cylindrical guide lug 21, preferably cast on in some'suitable manner, of a diameter to fit within the said blade back C.

The blade back C comprises a slotted tube of sheet metal having a tubular back 22 and provided with short downwardly rojecting flanges 23, along the edges of the s 0t 24:, the

tubular back 22 being adapted to receive 1on gitudinally the said castguide lug 21 on the blade B and the said flanges 23 bei adap t-' ed to bear against the faces of the lads B and to serve as clamping members to r' l'dy a 9 back C. Exteriorly the said blade back C is adapted to be received longitudinally within the uard piece A, the downwardly projecting an cs 23 located between the said downward y projecting flange l2 and the back clampin wing 18,150 that the said blade back C and the blade B are adapted to be received as a unitwithin the guard iece, the blade being clamped between the root and back members ofthe guard piecegi 9.0 rib.17 an "for back 10 and the said closed comb ortion 1,4,

in a plane at right an has to t e general alincment of the gua piece and at an angle to the wings suitable for convenience The outer end of the handle I) is internally threaded as at 24 to receive the threaded outer tip 25 of the strapping dc;

vice E. Inwardly from the said threaded tip 25, the said stroppin device E comprlses a slotted tube 26 adapte to be received within the said tubular handle I) and the inperend 27 up to the division notch 30 being essentially the counterpart-of the saidtubuwhen not in use may blanked 'out and rolled up to the tubular said blade back C with the blade B con' -ingfof the flanges 23, without appreciably p I ablyspaced and as;

lar back 10 of the guard piece ingly is adapted to receive and hold the vice.

results described are tion'th'at iseoinpact, efficient and reliable.

A and accord I blade B and blade baclp-C as a unit. The outer end 31 beyond the said division notch 30 serves conveniently as a handle, and i'na'y have a portion 28' roughened for a friction holding surface. The slot in the handle end 31 of the stropping device is essentially closed, so. that the edge 32 opposed to the blade B serves as aback stop for the same when inserted. The stropping device E be conveniently stowed, within the handle I), and secured in by means of the said threaded por- 24 and 25 of the handle and stropping The stropping device a strip of sheet metal,

away place tions device respectively. as described is made of formation and has the outer end closed by the said threaded tip As described. my razor comprises essentially' a blade holder, guard piece, handle and receptacle for the stroppingdevice as a unit, and combined with the same a stropping device all self contained and conveniently available for use. The blades are in diridnally removable and replaceable in the blade back, and the blade and blade back as a unit are removable and replaceable in the guardpiece and also in the stropping dc The stropping may be effected by means of. the stropping device provided'es scntially as is the case with an ordinary razor. The cutting away of the ends and corners 28 of the tubular back 10, exposes forconvenience in removal, the ends of the tained therein. The closed comb formation 1% of the guard piece A. avoids exposed projecting ends of the teeth. The single short guide lug 21 at the back of the blade serves effectively to hold the blade rigidly in the blade back in combination with the clampthe flexibility of theblade. The

effecting,

obtained by a construe of sheet metal, and comprising handle,

I claim as my invention 1- i 1. In a. safety razor, a flat, thin, sheet metal blade having a cylindrical guide lug adjacent to its back edge, a combined spring holder and a guard formed of sheet metal and comprising two clamping members suitthe said handle.

a holld'w back by which the said clamping members are united, and a second spring holder formed of sheet. metal and comprising two clamping members suitably spaced, one o the said members having a safety guard formed thereon, and a hollow back that connects the said two members and into which second holder the said first holder and blade are adapted to be received and held.

2. In a safety razor, a flat, thin, sheet metal blade having a cylindrical guide lug adjacent to its back edge, a holder formed of sheet metal and comprising two clamping members suitably spaced and a hollow back by which the said clamping members are united, and a second spring holder formed two clamping members suitably spaced, one of the said members having a safety guard formed thereon, and a hollow back that connects the said two members and into which second holder the said first holder and blade are adapted to be received and held, with a handle secured to and extending at a right angle to the length of the said second spring holder.

3. In a safety razor "having a removable blade, a blade having a back edge, a short guide lug on said back edge, a blade back fitting and adapted to receive said guide lug andprovided with blade clamping members, a holder fitting and adapted to receive said blade and blade back as a'unit, clamping members on said holder adapted to clamp" saidblade and blade back as'a unit, and a guard comprising an extension of one 0 said clamping members on said blade holder.

e. In combination in a razor having a reinovable blade, a handle, and a stropping device, the said handle tubular in formation,

having an open end, otherwise complete and unbroken in its inclosing walls and provided with an internal screw thread adjacent said end, the said stropping device generally tubular information, receivable withinsaid provided adjacent one end with a screw thread adapted to fit and be received by the said screw thread on said handle, and

at the extreme'end having a tip suitableformanipulation in inserting and withdrawing said stropping device and for a finish for oiiAnLns F. s MITn. Witnesses:
