Application filed August I6, 1905. Serial No. 274,494.

a citizen of the United States of America, and resident of Porter, Porter county, Indiana,

have invented acertain new and-useful Imrovement in Safety-Razors, of Which the lollowing is a specification.

' vide an improve My invention relates to safetyrazors, and contemplates an improvement on the forms of razor shown in my priorap lication No. 263,715, filed June 5, 1905, an No. 266,881 filed June 24, 1905. v

Obj ects of my present invention are to pro construction and arran ement whereby the head of the blade-hol er may consist of a casting suitably joined to the edge of a sprin y sheet-metal portion,"the said s rin y-meta portion being adapted to hold t e b ad'e firmly up surface of the said casting proved construction and arrangement where:

y a double-edged blade may be inserted endwise in the razor without danger of the blade slipping sideways and injuring one; of

its edges; ?to provide an improved construc-' tiori and arrangement whereby the lprojecting end-portionsiof a double-edged b ade can be more readily and firmly grasped by the thumb and forefinger, for the urpose' of removing the blade from the lade-holding member; to provide the head or holder with a slidin ing the' ladei and features of im crease the genera ability of a safety razor of this character. v I,

c To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed In'the accompanyingdrawings, Figure [is a side elevation of a safety razor embodying the principles of my invention.

As thus illustrated, my invention comprises a combined guard and blade-holder A,

i a blade B,

and handle 0. The said combined guard and blade-holder can be formed of one on the flat seat or top to provide an 1II1* rovement tending to in'- integral piece of metal 1, stamped and pressed or otherwise given the desired shape and construction, and a casting 2. As shown, the said combined blade-holder and guard constitutes the head of the razor, and is rigidly secured or united to the upper end of the handle C. Preferably, the said head or portion of the razor thus made in part of fstantially flat and horizontal portion a ada ted to serve as a seat or base upon which the lade B may restflat-wise. At each end,

j ecting flanges or edge-portions a and a the former being at the front and the latter at the rear oftherazor. Consequently, the portions 0/ are separated from the portionsa, by notches or recesses a At its rear, the head A is formed with an upwardly and forwardly projecting foot or springyclamping portion a, the same being adapted to reach upwardly and over and exert a yielding pressure upon the up or surface 'ofthe. blade B. In this Way, t e said blade-is held removably in place by springy pressure, the spring tension, however, being of .such character that the blade can be readily removed. The edge 3 of the portion 1 is adapted to be inserted endwise and retained in the groove 4 in the portion 2. its forward edge, the head A is provided with a guard having teeth a, this guard being of any suitable known or approved formation,that is, toothed or comb-like character.

As shown, the blade B is provided with parallel sharpened edges 6, and also with projecting end- 'ortions'or tangs 5. When the blade is ad usted in place, tangs b accurately fit the recesses or notches and it Will'also be understood that the accurately fits the space between the flanges or edge po'rtions at oppositeends of theseat or base a. Furthermore, the parts are so relatively formed and so proportioned, that the blade is held in place with one of its-edges ,properly positione the usiialor suitably formed teeth a With can be conveniently gras ed by the thumb and forefinger, and by a s ight upward presspringy foot or clamping springy sheet metal is provided with a sub it may be of the usual these lugs or 7 blade is preferably of such a length that it along the guard having the portion a is provided with upwardly proioo this arrangement, one of the lugs or tangs b sure, just suflicient to slightly flex the v portion a, the end normal position, the blade can then obviously 3 be readily withdrawn from under the springy' foot or clamping portion a Also, with this construction, the blades can be readily inserted in place, it being only necessary to grasp the blade at one end and then insert its other end under this s ringy portion a, and to then shove the blade along until its two end-portions snap into place under the pressure of the said spring portion. When a blade is being inserted or removed, the proj ection 5 on the end of the blade engages the groove 6 and thereby prevents lateral displacement. In other words, these small rounded projections slide in the grooveone at a time, of "course, depending on which way the blade is movingand thus guide the blade into and out of place in the holder. The groove 6 may be found useful or advantageous in other ways. Obviously, the construction is such that the blade is'removable independently of all other parts, and in such a way that the removal is accomplished without even mani ulating any other parts of the structuretlat is to say, the blade is removable and insertible by simply holding the handle C in one hand and grasping one end of the blade with the other hand. In fact, the entire razor comprises but two relatively removable members,to-wit, the combined handle and blade holder and guard, the same being all in one part, and the'blade, which latter is, of course, in one piece. The blade when removed leaves the 10ld61 without movable arts-that is, parts which must be adjusted when the blade is replaced, and the blade alone is removed. After the blade is withdrawn, there are no other portions to be taken apart or to be moved or manipulated in any manner Whatsoever. Consequently, owing to the extreme simplicity of the razor, it can be cheaply manufactured, and can ';'.be easily taken care of.

Notwithstanding theextreme simplicity of the structure, the r I find, thoroughly efiective, and satisfac ory for the purpose for which it is intended. Of course the spring jaw I can be made removable from the casting, but this is not necessary as far as the use of the razor and the removal and insertion of the blade is concernedat least, not when the tangs or handles b are used or maple long enough. Obviously, however, if suc is for any reason desirable, the spring iaw Z canbe removed before removin' the b ade. Also, the blade can be inserte in place, and the s ringj aw can then be inserted to hold the b ade upon its seat. I do not, therefore,

limit myself to the exact construction shownand described.

It will be seen that the portion 0. provides blade.

overhangin portions. which bear upon the top of the 'lade to prevent the latter from rising. portions which hold the lade against ed ewise displacement in any direction.

said overhanging means or portions can be located in any suitable manner, and upon any suitable portions of the holder, as, for example, upon a rearward extension of the holder. The said upstanding and overhang ing portions are comprised in the instrudisplacement upon the holder. It is by relative movement between these retaining instrumentalities that the blade. is releasably uncovered, leavingit free to drop or be lifted out of the holder. The said upstanding lugs or portions are disposed in position to engage the corners, or substantially at the corners of the rectan uiar blade, the holder bein also substantia y rectangular in form. A s iding connection 1s provided by which the relative movement between the retaining instrumentalities in a horizontal direction is effected for the purpose of releasably uncover ing the blade. By movement in ahorizontal direction, I mean a movement in the plane of the blade, or substantially in the plane there- The lugs a and a lprovide upstanding V mentalities for holding the blade fixed from of, or in a plane substantially parallel there with. As shown, the retaining instrumentalities comprise overhanging portions which are adapte to slide ina direction parallel with the length of theblade, but this may be varied without de arting from the spirit of my invention. he edge 3 is slidably mounted, and when moved causes the overhanging means to releasably uncover the portions provided by the spring member a are all integrally connected, orv joined together, inasmuch as the said member is composed of an integral piece of sheet metal; but this may also be varied without departing from the spirit of my invention.
