4 Claims. (01. 30-96) The principal object of this invention is to provide a device that when installed on a safety razor of the Gillette type will protect and shield the razor blade in the razor.

A further object of my invention is to provide ablade shield for safety razors that when installed on the razor when not in use will be rigidly secured to the razor and free of any independent movement relative to the razor.

A still further object of my invention is to provide a safety razor blade shield that not only successfully protects the. delicate edge of the razor blade, but automatically wipes the blade of moisture or other foreign matter at the time of attaching, thereby preventing undesirable rusting of the blade when not in use.

Astill further object of my invention is to provide an easily detachable or attachable guard shield for safety razor blades that. is light in weight, economical in manufacture, and durable in use.

These; and other objects. will be apparent to those skilled in the. art. 7

My invention consists in-the construction, arrangementand combination of the variousparts of the device, whereby the objects contemplated are. attained as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, in which:

Fig. 1 is a side view of my device directly after being first loosely assembled on a razor.

Fig.; 2 is a top plan view of my blade shield installed on a razor.

Fig. 3 is an end cross-sectional view of my blade :guardtaken on line 3- 3 of Fig. 1 and shows the position of the various parts of the razor relative to my device before the blade guard shield and razor are rigidly secured together.

Fig. 4 is an end cross-sectional view of my device rigidly secured to a razor and in use.

Fig. 5 is a perspective view of my safety razor blade shield and more specifically illustrates its construction.

Every one who travels knows the desirability of a guard to protect and shield the blade of a safety razor when not in use and which is usually carried loose in the grip or suit case. Although my device is highly desirable for travel usage to thus protect the blade and cuttable items in the carrying case, and to prevent items in the case from becoming soiled by the wet razor blade, the device is also quite desirable for use when at home. The reasons for this are that the blade is protected and preserved against rusting and against damage by coming into contact with items that might damage the razor blade. Also, my device prevents the accidental cutting of ones self when the razor is not in use.

Referring to the drawing, I have used the nu- 5- meral H] to designate the head plate of an ordinary safety razor. The numeral ll designates the guard part of such a razor and the numeral l2 the handle. As is well known, the handle l2 or a part of the handle 12 is threaded onto the shank l3 of the head I! in order to move the head Ill and guard portion H toward or away from each other. The numeral l4 designates the usual razor blade designed to be held between the head Ill and guard portion l I. It is to such a 15 razor that my device is applicable and which I will now describe.

I have used the numeral 15 to designate the housing of my blade protective device. This housing is open at both ends and has a longitudi- .20

, nal slot opening I 6 extending its entire length and located at its center top. The marginal edges of the housing at this slot I 6 are both bent downwardly and inwardly to conform with the longi- 7 I tudinal depressions in the guard II, respectively, which are just above the outer edge portions of the blade I 4 as shown in the drawing. By this construction of the housing a channel chamber in the housing is provided at each side of the longitudinal slot Hi. In each of these channels I have mounted a resilient, flexible bar element ll of suitable material such as cork. These bar elements I! each have a width less than the top portion of the housing above them, thereby the marginal edge portions of the housing adjacent its slot I6 will overlap or protrude substantially beyond these bar elements, respectively, as shown in Fig. 3.

Obviously, any suitable method may be used to hold the bar elements I! in their respective positions in the housing. In the drawing, I have formed downwardly extending indentations l8 in the top portions of the housing for engaging these elements. In the free face of each of these bar elements I I I have provided a Iongitudinal razor blade receiving slit l9. These two slits 19 are directly opposite from each other and are designed to receive the two cutting edge portions of a razor blade M, as shown in the drawing. They are so designed that when not engaging a razor blade they tend to completely close.

The practical operation of the device is as follows: With the razor in loose condition, that slidably engaging the inside bottom of the housing and the guard portion ll above the housing. The razor is thus moved until it assumes a position such as shown in Fig. 3. During this operation the cutting edge portions of the razor blade will automatically slide into and engage the two slit openings 58 of the resilient bar elem-ents W, as shown in the drawing. These slit openings H! are mere cuts in the bar elements and therefore this sliding of the blade into them will wipe the blade of all moisture and foreign matter. As these bar elements are of cork or like they will readily absorb any moisture frorn the blade and will not harm or damage the cutting edges of the'hlade. The bar elements I! are so spaced apart-that the head N3 of the razor will loosely rest between them and under the razor blade. a.

The slits is in the cork elements H are of such height from the bottom of the housing and in such positions relative to the marginal edge portions of the housing adjacent the slot It, that the top ofthe blade will be closelyadjacent for engagement with the marginal edge portions of the housing, which as we have seen, are bent downwardly and inwardly to conform with the curvatures of the guard ii and to engage the top of the razor blade as shown in the drawing. After the razor and its blade have thus been placed in my device it is merely necessary to tighten the razor by rotating the handle in the same manner as when it is desired to tighten the blade in the razor for shaving purposes. This tightening of the handle of the razor will bring the head and guard closer together, but the razor blade will not be flexed such as is theordinary casewhenit is desired to tighten the razor. to shave. The reason for this is that the top of the blade will be drawn tightly upwardly against the downwardly and inwardly extending marginal edge portions of the housing adjacent the slot opening it and the guard portion of the razor will be drawn downwardly onto these upper portions of the housing, as shown in Fig. 4, thereby rigidly securing the razor and its blade to my device and against accidental'removal or displacement. To! all intents and purposes, my shield becomes a rigid part of the tightened razor when not in use. In other words, the safety razor is first assembled to my device in a loose condition and then tightened. To remove the razor from my protective shield it is merely necessary to loosen the razor by rotating the handle in the opposite direction and sliding the razor longitudinally out of and from the device. The removal and insertion of the razor is facilitated by rounding the corners of the upper portion of the housing adjacent the slot 16, as shown in Fig. 5. Obviously, due to this and the downwardly and inwardly extending marginal edge portions of the housing adjacent the slot opening, the razor will be guided into its place in the device and out of the device and the razor blade will fall into line with the slits IS without much attention from the operator.

One of the important features of my device is that'during the insertion of the razor and even after the razor has been tightened, the razor blade will be maintained in a straight, flat condition.

Some changes may be made in the construction and arrangement of my improved safety razor blade shield without departing from the real spirit and purpose of my invention, and it is myintention to cover by my claims any modifiedforms ofstructure or use of mechanical equivalents which may be reasonably included withinftheir scope.

I claim:

1. In a safety razor and blade shield, a housing having a slot opening, and a bar of cork inside said housing having a slit opening designed to receive'theblade of the razor to be held.

2. In a safety razor and blade shield, a housing having a slot opening, and two spaced apart elements of resilient material inside said housing each having a longitudinal razor-blade slit opening designed to receive one of the cuttin edge portions of a safety razor blade.

3. In a device of the class described, a housing having a slot; said housing having its marginal edge portions adjacent said slot designed to extend between the guard portion of .a safety razor and a double-edged safety razor blade, and two spaced apart resilient elements inside said housing designed to engage the cutting edge portions of said razor blade. I

' 4. In a device of the class described, a housing open at both ends and having a centrally located side slot opening extending its entire length, downwardly and inwardly extending flanges adjacent said slot opening, and two slitted cork bars spaced apart from each other and; positioned at each side of said slot opening respectively.
