.SAFEQY RAZOR. APPLICATION IILBD JUNE 11, 1910.

ALLISON M. MAOFARLAND, OF PHILADELPHIA, PENN SYLVANLQ SAFETY-RAZOR.

Specification of Letters Patent.

vinterned Dec. 24, 1912.

Application filed June 11, 1910. Seria1 No. 566,425.

To all whom it may concern. I '5 Be it known that I, ALLISON M. MAC- FARLAND, a citizen of the United States, re-

siding in the city and county of Philadel' phia, State of Pennsylvania, have invented a new and useful Safety-Razor, of which the following is a specification.

My invention consists of. an improved safety razor of the straight type.

It further consists of improved means for guiding and holding'a double. edged blade.

It further consists'of improved means for removably guiding and holding such double edged blade.

It further consists of other novel features of construction, all as will be hereinafter fully set' forth. r i

For the purpose of illustrating my invention; I have shown in the accompanying drawings one form thereof which is at pres- Qent preferred by me, since the same has my improved safety razor.

been found in practice togive satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limitedto the precise arrangement and organization of these instrumentalities as herein shown, and described.

Figure 1 represents a perspective view of Fig. 2 represents a longitudinal section of the body portion and blade. Fig. 3 represents a trans verse section on the line mm in Fig. 1. Fig. 4 represents a transverse section on the line y-y in Fig. 1. Fig. 5 represents a face view of the body portion. Fig. 6 represents a face view of the blade.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :The razor has a flat body portion, .1, formed with guard-fingers, 2, upon its side edges, and with a shank, 3, which may be pivoted in a handle, 4:, of the old and well-known form in straight razors, although, if desired or required, the shank may form the handle or be rigidly secured in a handle. One face of the body has a longitudinal guide formed by a rib, 5, the ends, 6, of which are raised from said face and formed with laterally projecting spring fingers, 7 forming yielding retaining members,four such fingers being illustrated at each end of the rib. The blade 8 is thin and fiat and has prefer ners. A longitudinal slot, 10, open at one end, is formed in the blade, and said slot is .of a width to snugly engage and slide upon the rib, and the blade is'of a thickness which will allow the same to slide beneath the ably two cutting edges, 9, and rounded cor spring fingers and to be held by the friction of the same against'endwise movement.

In practice, the blade is slid with the open end ofits slot upon the rib and beneath the spring fingers, which will frictionally retain the blade .in position against lengthwise movement. The blade may easily be slid out from the rib and retaining fingers for the purpose of sharpening or renewal.

Both edges of the blade may be used so as to shave in opposite directions without the necessity of reversing the razor.

Inasmuch as the' rib is substantially only.

as high as the thickness of the blade, and.

the spring fingers require but slight thickness, the blade holder and the blade are comparatively thin and light and need not be thicker nor heavier than-the blade of an ordinary straight razor. This is of considerable advantage, inasmuch as the majority I of existing razors of this type, on account of the. construction of their blade-holding means, are considerably thicker and in some instances, considerably heavier, than the common straight. razor, and their thickness has prevented such razors from being applied fiat to the face for lightshaving. The present razor can, on accountof its thinness and that of the spring fingers be applied equally as flat as the common straight razor.

Having thus described my invention, what I claim as new and desire to secure by Let- 3 ters Patent, is

1. In a safety razor, a body portion, a longitudinal guide rib upon one face of said body portion and having raised ends provided with laterally projecting spring retaining fingers, and a blade having a longitudinal slot open atone end and adapted to slide upon the rib and beneath the spring fingers to be frictionally retained by them against longitudinal displacement.

2. In a safety razor, a body portion, a longitudinal guide upon one face of the same, a blade having a longitudinal -.slot open at one end and fitted to slide upon said members supported above the body portion and between which members and the body portion the blade is seated, said members frictionally and yieldingly engaging the 1 face of the blade beyond the opposite ends ot' the rib and forming sole means to prevent longitudinal displacement of the same.

3. In a safety razor, a body portion, a longitudinal guide rib upon one face of the l body portion and having spring fingers 1atplacement.

4. Ina safety razor, a flat body portion provided with guard fingers at its edges, a longitudinal guide rib upon one face of said body portion and having raised ends formed 1 with fiat laterally projecting spring retaining fingers, and a blade having a longitudinal slot open at one end and fitted to slide upon the rib and beneath the spring fingers f to be frictionally retained by them against longitudinal displacement. I

- 5. In a safety razor, a body portion havi ing a rib, a blade having an open ended slot with straight and uninterrupted edges to receive said rib, and spring fingers projecting outwardly at the ends of said rib to friotionally engage the face of said blade to retain the same against longitudinal displacement and disengagement from the rib.
