Application November 18, 1950, Serial No. 196,388 2 Claims. (01. 30-62) The present invention contemplates the provision of a very compact unit substantially the size of. a fountain pen which will contain in a single housing the essentials of a, razor and.

toothbrush kit. There-are many persons'whose nomadic habits require that they have a toilet kit that can be easily transported upon the per- 'son.-; This is true of travelers generally, of sportsmen,-hunters, fishermen, and the like, but most especially is it true of members of the armed services; Members of the armed ground forces I are constantly finding themselves in positions ,where in order to carry their essentialcombat weapons and impedimenta they must many times desirable that a unit of this order be small enough that it can be carried clipped into a pocket, similarly to a fountain pen. M Our recent wars have shown great ingenuity .on the part of manufacturers endeavoring to supply toilet kits and equipment suitable for personal us but in those instances observed the I problem has generally been solved by re-combining; or' re-housing existing types of equipment, and; when so employed the bulk of the same became so great that they must of'necessity be carried in a kit bag and thusmany times are not available for use atthe time conditionspermit of their use. With this present invention in its preferred form a person can carry conveniently,

as clipped into a shirt pocket, a single container which will house a toothbrush, a razor kit, and

asupply of razor blades. The housing, being .shaped similarly to a fountain pen and provided with asimilar type of clip, serves as a handle for the use of either the toothbrush or the razor.

,With slight substitution of parts it then follows that by having two such units a person could have a toothbrush, together with a supply of tooth past'e'and, in .a separate unit, have a razor',com-

plete with blades and a supply of shaving cream.

This latter modification would require a duplicationlof the handle portion to a degree ,but still thebulk would not be excessive. To achieve these results" it is .necess'ary that the functioning ele- 'ments', the razor head and the tooth brush head propen'ibe carefully re-designed so as toadapt ithem n this use. This present application showsonesuch'preferred development,

The principal object of the invention is to provide an improved razor head.

A further object of this present invention is to provide in a single container similar in size and shape to a fountain pen all the elements necessary for brushing ones teeth, shaving the face, and trimming or cutting the hair.

A further object of this invention is to provide in a single unit that is compact and easily carried all the essential elements of a toothbrush and safety razor with a supply of blades, in which each of the elements are fully protected until the moment of use occurs. 1

A further object is to provide a safety razor of very compact form in which blades suitable for shaving the face or for trimming the hair can be employed.

Further objects of the invention are to provide means whereby a storage compartment is provided for either the-razor or the toothbrush head and in conjunction therewith a chamber equipped with expelling mechanism so that suitable cream can be carried for use with the razor, on one hand, or the toothbrush on the other.

Further objects, advantages and capabilities will be apparent from the description and disclosure in the drawings, or may be comprehended or are inherent in the device.

In the drawings:

Figure 11 is a longitudinal sectional view in which the handle portion is shown without shading, so as to better illustrate the manner in which the razor blades and the toothbrush head are stored within the same.

Figure 12 is a perspective view further illustrating the form of razor head used With this device.

Referring more particularly to the disclosure in the drawings the numeral 10 designates the handle of my travelers kit. ThisI' preferto form after the general proportions of a'fountain pen, to the end that it may beiconvenientlycamied about in the pocket, and the same may beprovided with a spring clip l3 following outthefountain pen carrying principle. Adapted to be secured to one end of handle 10 is a razor head I2.

This is made after'the general principles of safety razors except thatit is of modified structure to adapt it to the compact arrangement which is'an essential of the present invention. To facilitate inasmuch as the razorwill berepeate'dly removed and be reassembled into the shaving position it has been found desirable to provide an internally threaded metal bushing 1'6 which can be molded into the body and which will'have threads that will be durable and give lasting usefulness over long periods. Co-acting with the internal threads of bushing I6 is the joiner'portion 18 which is formed as part of the razor head. This joiner portion normally extends outwardly from the back surface of therazor head, positioned longil tudinally ofthe razor at right angles to the same, and transversely of the razor 'head'it is set at an angle so as to provide the convenient angular positioning of the razor bladewith respect to the longitudinal axis of the handle much after the teachings of the presentsafety razor construction. Joiner portion I8 is exteriorly threaded to coact with the internal threads of bushing is.

The razor head is provided with a'base member 2!! which is rather substantial in design and preferably formed .ofmetal although certain of the plastics might be made to serve. The exterior face or thatface opposite from the joinerportion [.8 is longitudinally .provided with a transverse curved surface. The transverse section shown in Figure 2 is illustrative of about the curvature that has been found most. acceptable. The shaving edge of base member 20 is reduced or tapered and terminates in aplurality of similar'teeth 22 whose construction will be best understood by a study of Figures 2, 3, and 4. Teeth of this order are common in safety razorbladeconstruction and their function in this instance is similar to that of an ordinary'safety razor. An elongated clamp member is disposed on the outer'surface of base member 20 and spaced away from the same substantially the thicknessof therazorblade used :in the .device. Clamp member .24 terminates in downturned ends 26 which are given considerable gerat-ed thickness. treme curvefound desirable in the blade it should bea 'yery -.-thin1blade, should be no thicker than blades.

not observable by the user.

between the clamp member 24 and. base member 20. The preferred cross-section of clamp member 24 taken transversely of the same is shown in Figure 2 and as it is outwardly curved on both sides it produces a convexo-convex section.

Clamp bar 24, due to its rather substantial cross section and substantial down-turn portions 26, may be merely snap-clamped onto base 20. This is a mostiideal arrangement in that minor variations of pressure can be applied to'the razor blade and thus hold it securely in position; yet the "frictional grip must be such that the razor blade canzbe easily inserted and removed.

Razor blade 28 is shown in Figure 2 in exag- Actually, because of the exthe thinnest of the presently available wafer Blade 28 is seated in its adjacent position by shoulder portions 30 which abut the curved end portionsflfi. Asia convenience in removing blade L28, longitudinal slots are zprovided as 31, on'e'at each-rend of'theiblade so that -the finger or thumb nail: or some other suitablesobject canbe inserted in these slots' and make the vvithdrawa'l of the blade :a: convenient operation. In

Figures 6 and '7 have 'been illustrated the two types of blades normally supplied with' this razor. The wider of these two blades shown iri Figure-6 is the one normally used for shavingthe:skimand the narrower blade,- shown 1 in "Figure 7, has been found to be more satisfactory for cutting the hair, particularly f or trimming the margins of the hair, the difference in the two blades -be'ing that portion extending outwardly from notches'ill to the cutting edge 32 of the blade. This-means in fact that the narrower blade "willhave" its =-edge --withdrawn upwardly from the position shown Figure 2 and, while serving to cut the hair quite effectively or for dry shaving, would "not "be as suitable for 'soap ore-ream shaving, andbythe same token, thereis a l-essened' da-nger of cutting oneself, particularly when the blad-e is used withoutanysoap or other preparation and for the most part will be used under conditions that are When the "*blade shown inFig-ur-e "7 is used "in dry shaving, the

blade engages guard very tightly and is absolutely safe as thereis'not space between the blade and teeth 22 due to the curvature of the blade. This sameprincipl'e canbe applied in making a curved razor, that ca-n' be used to shavethe-arm pits and-other places of a rounded nature.

In Figureli I have shown'the preferred :form of handle when my device is to be'used "merely as aqrazor. Under "such "conditions "an intermediate'portion gof "the handle :42 providingthe *bore fl' is .adaptedto be securedto' the topjportion I l by means of co-acting external "and .internal threads .44 and "46 respectively.

Tofacilitate charging chamber 50 with shaving cream the interior bore of boss is threaded at 59 to accept a standard threaded end of a collapsible tube. To charge/the tube is screwed in place,

piston 16 is retracted-to plug 62 and the same is it can have molded into it an operating screw for the cream expulsion mechanism. The end portion, however, must be capable of free rotation and, to achieve this, a preferably metal ring member M is provided which is threaded onto barrel by the internal and external threads 66 and 68. Ring 54 is preferably molded onto closure 62 so that a free slipping surface is achieved so that continued rotation of closure 62 will have no tendency to wear out the threads that hold the device in place.

Longitudinally disposed within bore 50 is the cream expulsion screw 72. This terminates in an unthreaded end portion 14 which is deformed or configured so as to provide a firm gripping surface so that it, in effect, becomes a part of closure 62 and turns with it at all times. Disposed upon the threaded portion of screw 12 is the cream expulsion piston 16. This piston has been found to have considerable frictional engagement with the cream; consequently as the screw 12 is turned by revolving closure member 62 the piston will be caused to travel along the length of the screw and thus provide an expulsion means for the cream.

Under conditions where extreme compactness of a toilet kit is desirable, and this is especially true of the members of the armed ground forces, the modified form of this device as illustrated in Figure 8 through 11 make a very complete unit. In this instance bore 40 is used for the storage of a toothbrush element 80 which has a joiner portion 82 adapted to engage the internally threaded bushing It. When bore 40 is used for the purpose of carrying a toothbrush it is very desirable that adequate ventilation be provided; and while a certain degree of ventilation is provided through the bore of bushing l6 it is found desirable to supply one or more ventilating openings 84 at the opposite end of the chamber to the end that air can circulate therethrough and dry the bristles 86 of the toothbrush after the same has been used. In this connection it is desired to point out that the joiner portion 82 is substantially in a prolongation of the general plane of the ends of the bristles 85. This makes a toothbrush that is most convenient in use and permits the storing of the same in a small chamher, as 40, which would be difficult to do with toothbrushes of more conventional shapes.

When using this device as a complete travelers kit, employing the toothbrush in chamber 40, it is desirable to re-arrange the opposite end of the handle and to this end, portion 90 which is comparable to portion 5| of the preferred form, is provided with an offset partition having the axially disposed wall 92 and the transverse connecting walls 94 and 95. This forms, in effect, two compartments, a compartment 96 for the storage of razor blades, and at the other end a compartment 97 for the storage of the razor head l2. In order to eifectively house the razor head without increasing the overall length of the device which it is very desirable to keep within the limits of afountain pen so that a solider may carry the samein his shirt pocket, the modified closure member 98 is provided with an interior recess as 99 so that a portion of the razor head can extend into the same after the showing of Figure 11.

It is believed that it will be clearly apparent from the above description and the disclosure in the drawings that the invention comprehends a. novel construction of a combination razor and toothbrush kit for travelers.

Having thus disclosed the invention, I claim:
