GEORGE H. HAMILTON. OF NEW YORK, N. Y., ASSIGNOR TOBIlRHAM SAFETY RAZOR 0., O1

YORK, N. Y., A CORPORATION OF NEW sarn'rr-nazoa.

To all whom it may concern: a

New York andState of vented new and useful Improvements in Safet -Razors, of whichvthe following is a speci 'cation; 1

This 'nvention'relates to safety razors, the object in view being to provide a simple and inexpensivetype o razor of this character embodying. an improved construction of. holderfor the blade, wherebythe blade is firmly and securely held in use and" adapted to be easily and. conveniently applied and removed without liabilit of injury to the perator, and whereby t e pressure of the b ado-retaining means may be regulated and ready adjustment of the blade permitted for a and in such case the arms 12 will extend an ordinary or a close shave.

With these and other objects in view, the

invention consistswof the features of conedge to bear u struction, combination and: arrangement of parts hereinafter fully described and claimed, reference being bad to the accompanying drawing, in whiche- Figure 1' is a perspective view of a safety razor embodying my invention. Fig. 2 1s a side view of the same. view with arts broken away. Fig. 4 is a side view 0 a modified form ofrazor. Fig. 5 is a top planviewof the same.

The frame or holderconsists of a handle 5 carrying a triangularframe embodying a base plate 6 and a back plate 6 risin at ri ht angles from the/rear ed e of said ase p ate, the latter having: com 7 at its front on t f Stamped from t c base plate 6 and back plate 6" are inclinedstrips 8 extending be.- tween the upper edge of the backplate and front edge of the base plateandfinterrnediately. downwardly bowed or dished so as to provide reduced bear-in oints, edges or rests 9 to support the b at e 10 at its front and rear edges and at or near its ends, thus reducin friction as the blade is inserted and removed. The handle 5 is fixed to and extends at ri ht angles from the base late 6 and in a plane parallel with the bac plate 6, as shown, and, hence, the rests 9 and a blade 10 bearing thereon inclinedownwardly and forwardly at an obligue angle to the Specification of Letter- ?atent.

the blade ata proper angle to be held easily The bladeis retainer in its place on the i frame and against the rests by means of the pressure bar 11 which unites the ends of the s ring arms 12 which rise from the back of t e base plate 6 andproject forward, and

these spring arms may be bent and thus adjusted to causethe bar 11 to bear with a greater or less degree of pressure upon the a blade and depressit between the front and rear bearing points, so as to elevate or lower the edge 0 the cutting blade withrelation to the comb 7. If desired, the 11 per edge ofthe back plate may be forms with an o wardly pro ecting sto shoulder 6 against w ich the rear ed e of t e blade 10 bears to hold said bade rom rearward movement,

from this shoulder. This adjustment of the cutting edge isfor the purpose of giving more or less cutting effect'to the blade so that a close or coarse shave may he obtained to the liking of the user. The razor maybe sold with the pressure bar set to act with a desired ressure force, which may be regulated su degree desired.

lnrthe modified form shown in Figs. 4 and 5, the blade 10 is supported along its front and rear edges by means of forwardly and rearwardly extending onsets forming shoulders or rests 13 and 13 which extend along the length of the holderrespeetively at the front edge of the base plate and at the upper edge of the back plate. The bar 11 and and without materialstrain when the blade is disposed in working osition.

quently by the purchaser to the s ring arms 12 are also used in this form and t eirpressure not only holds the blade lirlnly, but maybe so regulated as to meet the re- T he rear edge of the bladegrestsagainst an upturned longitudimil stopshou der 14 at thcrear edge of the rest 13 on the back plate, and fingers 15 on said shoulder are provided to overlap and prevent upward movement of the rear edge of the blade at that point. This shoulder 14 corresponds to the shoulder 6 shown in Figs. 1, 2 and 3. -This arrangement of the blade and its holder crmits of the instant inscrtion or remova of the blade and allows the removal and insertion of dill'erent blades for trial until one suited to the use of the owner is secured. It will be understood. that in removing or inserting the blades they are caught at their ends by the thumb and forefinger and slid longitudinally into place from either side of the holder between the spring bar and the rests, and this manner of handling precludes any danger of cutting the fingers or dulling the cutting edge. I

It will be seen that the cutting edge 10 of the blade is chisel-shamd and it is obvious that a. different shaving effect may be pro duced in accordance with the manner in which this blade is turned. The reversal of the blade is equivalent to an adjustment to carry the edge awayfrom or toward the comb to secure a shave of more or lesscloscness.

It is obvious that, within the scope of the invention as defined in the claims, other modified means for holding a blade by spring pressure between its supports may be adopted Without departing from the essential features above described.

l-Iaving thus fully described the invention, what is claimed as new is:

1. A safety razor embodying a triangular frame stamped from a single piece of sheet metal and embodying a base plate and a back plate rising at right angles from the rear edge of the base plate, the front edge of said base plate being formed with a comb, a handle fixed to the base plate and extending at right angles therefrom parallel with the.

back plate, offsets on the frame at or near the front edge of the base plate and upper edge of the back plate and forming rests inclined at an oblique angle to the base plate, a blade adapted to bear upon and be supported by the rests at a correspomling angle to the base plate, and a spring clamp carried by the back plate to engage the blade between the rests and hold the same pressed against said rests.

2. A safety razor embodying a triangular frame stamped from a single piece of sheet metal and embodying a base plate and aback plate rising at right angles from the rear edge of the. base plate, the front edge of said base plate being formed with a comb, a handle fixed to the base plate and extending at right angles therefrom parallel with the back plate, offsets on the frame at or near the front edge of the base plate and upper edge of the back plate and forming rests inclined at an oblique angle to the base plate, a stop shoulder extending upward from the upper edge of thev back plate, a blade adapted to rest upon and be held by the rests at a corresponding angle to thebase plate and to bear at its rear edge against said stop shoulder, and a. spring clamp extending from the stop shoulder to engage the blade between the rests and press the same against said rests.

3. A safety razor comprising atriangular frame stamped from a single piece of sheet metal, said frame embodying a base plate and a back plate extending at right angles from the rear, edge ofthebase plate, the

l front edge of the base plate being provided with a comb and an offset bearing shoulder along the inner edge of the comb and the upper edge of the back platehaving a rearwardly projecting offset bearing shoulder, the said. bearing shoulders being inclined at an oblique angle to the plane of the base plate, a handle fixed to the base plate and extending at right angles therefrom parallel with the back plate, a blade adapted to rest at its frontand rear edges upon said bearing shoulders and supported thereby at a corresponding angle to the base plate, and a spring clamp carried by the back plate for pressing said blade against said shoulders.

4. A safety razor comprising a triangular frame stamped from a single piece of sheet metal, said frame embodying a base plate and a back plate extending at right angles from the rear edge of the base plate, the front edge of the base plate being provided with a comb and an offset bearing shoulder along the inner edge of the comb and the upper edge of the back plate having a rearwardly projecting offset bearing shoulder, and a stop shoulder projecting upward therefrom, the said. bearing shoulders being inclined at an oblique angle to the base plate, a handle fixed to the base plate and extending at right angles therefrom parallel with the back plate, a spring clamp carried by the back plate, and a blade adapted to rest at its front and rear edges upon said bearing shoulders at a corresponding inclination to the back plate and bear at its rear edge against said stop shoulder and to be held in contact with said shoulders by said, clamp.

In. testimony whereof I affix my signature in presence of two witnesses.
