T0 all whom z't may concern.'

Be it known that I, ISAAC N. WEBER, a citizen of the United States, and resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and useful Improvement in Safety-Razors, of which the following is a full, clear, and exact description.

This invention relates to cutlery and has particular reference to safety razors.

Among the objects of the invention is to provide a safety razor of peculiar form and construction adapting it for convenient carrying in the pocket, the entire construction being no thicker and but slightly broader in practice than an ordinary lead pencil, while the length thereof is materially less than that of a pencil.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is a plan view of the device complete adjusted for use.

Fig. 2 is a vertical longitudinal section of the same.

Fig. 3 is main parts, and closed.

Fig. 4 is a vertical transverse section on the line 4-4 ofl Fig. 2; and

Fig. 5 is a detail pers ective view -of one of the blades, a supply o which may be carried in the end of the handle.

Referring now more particularly to the drawings I show my improved safety razor in a simple and practical embodiment comprising a hollow handle 10 of substantially elliptical cross section and made of any suitable thin strong material such as sheet metal. Both ends of the handle are open, the inner end at 11 being cut off substantially in a plane at right angles to the axis of the handle while the outer end 12 may be somewhat convex.

Fitted into the inner end 11 is a holder 13 having an extension 13 adapted to telescope into said inner end -of the handle. This a longitudinal section of the but with the device collapsed holder is 'intended to hold av plurality of spare blades 14 for the razor.

Slidably fitted in the outer end of the handle is a stem 15 having formed therewith or secured thereto in any suitable manner a shank 16 from which extend inv opposite directions two series of' fingers 17 forming guards fora purpose well understood in the safety razor art. shank is formed a head 18 having a transverse slot 19 formed therein, the metal betweenthe slot and the extreme end of the head constituting a pivot' 20, the axis of which is perpendicular to the axis' ofl the shank. From Figs. 2 and 3 it will be noted that the guard lies in a plane at one side of the center of the axis of the handle or close to the plane of the inner surfaceof one of the broader sides of the handle. More specifically, however, the blade 14 whenY fitted in operative position-upon theguard lies practically in alinement with the said inner surface of one broader 'side of the handle.

At the outer end of thel At the inner end of the guard are formed l a pair of short upstanding lugs 21 and at the outer end of the guard are similar guards 22. The guards of each pair are spaced laterally from the axis of "the guard far enough to receive the adjacent corners of a blade 14 when clamped in position. In other words the two pairs of lugs 21 and 22 e111- brace the corners of the blade so as to hold the blade indeinite position with respect to the axis of the implement and with the cutting edges of the blade properly spaced from theguard fingers. It is to be noted that the preferred form of the blade has two opposite ,cutting edges both held in convenient operative position.

' The keeper 23 serving to lock the blade in position is formed preferably of spring metal and is connected to the head. 18 for free swinging movement around the pivot 20, as by means of a loop 23 formed at one end of the keeper. The opposite or otherwise free end 24 is adapted to be inserted into a pocket 25 formed by al slight swell or Ionvexity at the upper face of the outer end 12 of the handle. The width of this pocket as indicated in Fig. 4 is made to conform to the width of the end 24 of the keeper so that the keeper, when introduced into the pocket by a slight inward or telescopic action of the slidable stem 15 will be held positively from lateral movement and it together 4with the guard will be held frictionally from outward movement, so that the keeper in practice is not likely to release its proper hold upon the blade.

The stem l5 is positively limited in its reciprocating movements in both directions by any suitable means. For instance the inner end of the stem is adapted to strike against a lug 26 which may be formed in the handle as by striking in a fragment thereof. At thc outer end l2 of the handle are formed one or two lugs 27 which extend inwardly toward the center of the handle in position to be struck by shoulders 28 formed on the lower face of the stem by the dressin down of a portion of the front end thereof as indicated at 29 of Fig. 4. The length of the keeper is such that the free end 24 thereof is adapted to be received in the concavity formed at 29 when the device is to be folded. See Fig. 3. In this position the keeper is swung outwardly and downwardly around the pivot 20 of the head in which position it is expedient for the stem carrying the guard and nested keeper to be telescoped into the handle until it is stopped by the lug 26.

In this movement the keeper swings in a plane perpendicular to the plane of the blade and guard and practically through a full circle, or from one side of the guard to the other side thereof. By this fact it is expedient for the inner or free end of the keeper to coperate in an interlocking manner with the pocket 25. In other words since the blade lies against the guard in alinement with the inner edge or surface of one side of the handle there is no room for the keeper to be telescoped with the guard and stem Iinto the handle when the keeper is acting to hold the blade in operative position. In the inoperative position of the keeper, however, it is swung around through a circle so as to lie adjacent to the inner or opposite side of the guard where there is ample room for the keeper and guard to telescope into the handle. In this position the head portion of the guard projects slightly so as to be grasped for 'drawing out the stem into operative position. When the device is to be used the cap 29 which is normally carried upon the outer end l2 of the handle inclosing the guard will be removed and the head 18 of the guard will be grasped by the thumb and linger and drawn out until the shoulders 28 strike the stop lugs 27. The keeper may then be swung freely around the pivot 20. A blade which may be taken from the holder 13 is then dropped into place upon the guard between the lugs 2l and 22 and the keeper is then sprung down flatly upon the central portion of the blade bringing the free end 24 thereof into alinement with the pocket 25. The

'end of the nannte guard and connected blade are then forced inwardly, bringing the end of the keeper into the pocket and the device is ready for operation.

A safety razor made in accordance with this invention is not only safe and practical, but is of the utmost simplicity and cheapness. Furthermore this razor is of exceedingly convenient structure with respect to transportation as well as manipulation.

I claim:

1. In a safety razor, the combination of a tubular handle of a fiat oval form in cross section, a guard, a member slidable within the handle and holding the guard in a plane at one side of the center of the handle and approximately in the plane of the inner surface of one side of the handle, a blade, and means carried by the guard to hold the blade in operative position against the outer face of the guard, said holding means including a keeper pivotally connected to the outer guard and adapted to swing through approximately a full circle around its axis from one side of the guard in operative position to' the other side of the guard in inoperative position whereby the keeper is adapted to telescope with the guard into the handle.

2. In a safety razor, the combination of a handle, a guard slidabley longitudinally into and out of the handle, the outer end of the guard constituting a head provided with a pivot the axis of which is transverse to the axis of the guard, a blade for the guard, means carried by the guard to prevent lateral movement of the blade with respect to the axis, and a keeper to hold the blade from outward movement, said keeper comprising a loop embracing said pivot and movable around the axis of the pivot so as-to lie liatly against the central portion of the blade, the inner end of the keeper being movable into a pocket formed at the guard end of the handle to prevent undesired movement of the keeper away from the blade.

3. In a safety razor, the combination of a tubular handle, a stem slidable therein, means to limit the endwise or sliding movement of the stem, a guard connected to the stem and movable with the stem within the handle, a blade, 'means carried Iby the guard to engage the ends of the blade to hold the same from lateral movement, and a bow shaped keeper permanently connected at its outer end to the guard and movable with respect to the guard into position along the central part of the blade to clamp the blade from outward movement, said keeper cooperating with the handle to prevent the guard and attached blade from sliding into the handle.
