The invention relates to a safety razor and more especially to a rotary adjustable safety razor.

The primary object of the invention is the provision of a razor of this character, wherein the head of the razor is in the form of a circular body embraced by a sleeve, the latter having cut and bent therefrom cutting blades, these being uniformly spaced from each other and each is adapted for shaving, the razor being of novel construction and is readily adjustable for the use of the cutting edges in accordance with the condition of the same.

Another object of the invention is the provision of a razor of this character, wherein the cutting element is made from a blank of sheet steel bent into cylindrical form and having struck therefrom a series of cutting edges, these being properly angled or disposed tangentially to the cylindrical formation and are usable singly for shaving purposes, the cylindrical element being readily adjustable for the selection of the individual cutting edge for use during shaving.

A further object of the invention is the provision of a razor of this character, wherein the head thereof is formed with a gutter for the catching of spent lather and cut hairs during the use of the razor in shaving, the cutting element of the razor being readily adjustable so that a selected cutting edge can be brought into position for service at the will of the user of the razor and in this position will be held fixed, thus assuring extended service without danger of the cutting of the person while shaving.

A further object of the invention is the provision of a razor of this character, which is extremely simple in construction, thoroughly reliable and effective in operation, assuring comfort to a user without liability of the cutting of the skin during shaving, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Referring to the drawing in detail, the safety razor constituting the present invention comprises a roller-like head or a circular body 10 which has centrally fitted therein at one end the axle stub 11 formed with and at right angles to the stem 12 of a handle 13, the stub being held secure through the medium of a fastener or key 14 suitably fitting the head or body 10 and such stub so that the body or head will be prevented from rotation on this stub 11.

Encircling the head or body 10 is a longitudinally split sleeve-like cylinder 15 preferably made from a blank of sheet steel A normally flat and having cut and struck outwardy therefrom the series of cutting edges 16, these being uniformly spaced from each other and are disposed longitudinally of the cylinder 15, they being disposed tangentially to the latter and are adapted for use singly in shaving. The cylinder 15 snugly embraces or clamps the head or body 10 and is inherently expansible and contractible for snug tight embracing action through contraction thereof while on expansion the cylinder 15 can be loosened from the head or body for the turning thereof under adjustment of the same. In this manner a cutting edge 16 can be selected for service in shaving.

The cutting of the edges 16 and the angular disposition of the same with respect to the cylinder 15 provides next thereto slots 17, the head or body 10 being provided with a substantially V-shaped channel or groove 18 therein which is disposed longitudinally of the same to afford a catch trough for cut hairs or spent lather during the use of the razor and such cut hairs and lather will pass through the slot 17 in confronting relation to the trough 18 for deposit in the latter.

The cylinder 15 next to the outer end thereof is formed with an instruck annular bead 19 fitting in a companion seat or groove 20 in the head or body 10 so that the said cylinder 15 when embracing the latter will be held against slippage longitudinally on said head or body.

The cylinder 15 at the other end has formed therein notches 21, these aligning with the edges 16 and any one of the same is adapted to accommodate the stem 12 of the handle 13 when the bead 19 is engaged in the seat or groove 20 and thus in this manner the cylinder 15 is held against rotation or turning upon the head or body 10 while one of the cutting edges 16 with its companion slot 17 aligns with the trough 18 in the said head or body so that this cutting edge 16 in such alignment will be the active edge during shaving while the cut hair and spent lather will be deposited within the trough 18 during the use of the razor.

By the turning of the cylinder 15, any selected one of the cutting edges 16 may be brought into position for service in shaving.

In Figure 5 of the drawing the cylinder 15 has exteriorly applied thereto a protective covering 22 which is of cylindrical form and has provided therein overlying the edges 16 tearing sections 23 created by weakened lines 24, these having pull tab ends 25 beyond the outer end of the cylinder 15 so that on the tearing of a selected section 23 a cutting edge 16 of the cylinder 15 can be exposed for use, normally these cutting edges being covered and protected by the covering 22 when the razor is not in use. The stem 12 is provided with a slit 26 effecting a flat contact 27 for the notches 21, this being clearly shown in Figure 6 of the drawing, and thus there is no possibility that the cylinder 15 will turn on the body 10 when the razor is in use.

When it is desired that the cylinder 15 be adjusted to bring a cutting edge 16 into working position for cutting or shaving purposes, it is only necessary to press upon the notched end of said cylinder 15 causing the annular bead 19 to ride out of the channel or groove 20, the said cylinder 15 being longitudinally split and inherently expansible allows the riding of the bead out of the groove or channel so that the stem 12 becomes disengaged from a notch 21 in the said cylinder 15 and the latter now being free from locked engagement with the stem 12 may be turned on the body 10 to bring a selected cutting edge 16 into workable position. Thereafter the cylinder 15 is shifted on the body 10 to have the bead 19 ride into the channel or groove 20 and also to bring the stem 12 into a notch 21 for the locking of the cylinder 15 on the said body 10.

The edges 16 are sufficiently spaced arcuately from each other so that only one of these edges will be in cutting relationship with a user for the cutting of hair or shaving purposes. As it will be noted, the circular contour of this cylinder 15 protrudes these cutting edges 16 materially in different planes with respect to each other in their distributed relationship peripherally about the said cylinder so that but one edge 16 is active at a time in the use of the razor and there is no liability of the inactive edges 16 cutting or injuring such user.
