United States Patent SHAVING IMPLEMENTS Jacob L. Kleinman, Arverne, N. Y. v Application July 29, 1953, Serial No. 371,065'

19 Claims. (Cl. Sli-40) 'I'his invention relates to the construction of shaving implements in general and more particularly to a type known as an injector razor or magazine feeding razor, which is constructed in a manner wherein the blades are fed from the magazine directly into the razor head and held in position in a locked manner for shaving purposes.

My novel construction is capable of being utilized in connection with Various types of shaving implements, but particularly so with a type of an injector razor adapted to hold a blade having two individual opposite cutting edges.

In accordance with my invention, I produce a shaving implement including a razor-head structure comprising an inner member having a top portion or platform adapted to form a seat for a razor blade having two individual cutting edges, and an outer member having a roof or plate portion adapted to hold the razor blade secured to such seat for shaving purposes, and wherein the said head structure is provided with a wall having a zig-zagged or corrugatedly-shaped slot to receive a zig-zagged or corrugated linger of a blade magazine to move or separate the platform and the plate portion from each other to an extent whereby a razor blade having two opposite cutting edges may be positioned therebetween without damaging such cutting edges.

To illustrate the ordinary commercial utility of my novel shaving implement in daily life, a shaving implement constructed in accordance with my invention, of whatever style or type it may be made, could be utlilized to great advantage. For illustrative and clarification purposes I desire to point out the following: Many attempts have been made to produce an injector razor wherein a double edged razor blade could be inserted therein directly from the blade magazine, but none of such attempts have met with any success. The reason for such unsuccessful attempts are as follow: It should be borne in mind, that for the purpose of moving a double edged razor blade from the magazine into the razor head, particularly so when such blade is to serve the purpose of pushing the used blade out of the head structure, the razor head must be so constructed that when the magazine finger is placed within the finger-slot of the head structure such linger must perform. the following functions.

First, the lugs engaging the cutting edges must be moved (horizontally or cross-sectionally of the handle) farther apart from each other to an extent whereby neither one of the two opposed cutting edges of the blade could touch such lugs while such blade is being moved into desired position for shaving purposes.

Second, the portions of the blade seat and of the roof section, of the razor head portion situated adjacent to the outlet slot of the magazine, must be separated from each other (longitudinally of the handle) only to such an extent whereby the blade may be permitted to enter the space therebetween; for example, if the thickness of the blade is .010 inch then the space between the front portions of the blade seat and of the roof portion, when so separated from each other, should be about .012 inch,

2,734,264 Patented Feb. 14, 1956 but the remaining portion of the space between such blade seat and roof portion must be of a lesser degree; (as a matter of fact, the rear portions of such blade seat and roof portion should, by means of spring tension, engage each other) so that when the incoming blade enters the space between the blade seat and the roof portion it will engage and eject, endwise, the used blade from its position within the razor head without distortion while such incoming blade is being held in frictional engagement within the remaining portion of the space between the blade seat and the roof portion. And when the magazine finger is removed from the head structure then such blade must be clamped evenly and rigidly between the portions of the blade seat and the roof portion, and also between the lugs engaging the end portions of the cutting edges, to an extent preventing lateral movements of such blade when positioned upon its seat for shaving purposes.

Third, the eXtreme rear end portions of such platform seat and roof portion must be tapered to an extent whereby when the finger moves the front end portion upwardly from the platform seat the rear end portions will rest upon a full surface and not upon edge portions so as not to distort the operation of the parts.

It can therefore be seen that an injector razor, to be practical and useful in combination with a razor blade having two opposite cutting edges, must be built to be able to perform the above-mentioned functions; none of the injector razors designed to hold a double-edged razor blade are able to perform such functions. It is for this reason that attempts, heretofore, to produce a practical and useful injector razor to be used in combination with a double-edged razor blade has been unsuccessful.

Whereas an injector razor made in accordance with my invention, which is designed especially to perform the above-mentioned functions, is fully applicable for use in combination with a double-edged razor blade. The blade seat is provided with two opposite comb-sections each to support its adjacent cutting edge. The blade can easily be fed from the magazine linto the razor head in a manner whereby the blade will be held under yieldable frictional engagement during its slidable movement, and be held, firmly, in its seat for shaving purposes.

It may also be pointed out that the corrugated slot is of a shape tapered, gradually, downwardly to a narrower size than that of its upper section, so that the magazine linger (which is of similar shape cross-sectionally), when inserted into the slot, will more readily move or separate the upper portions of the head structure further apart from each other without strain upon the movable parts of such head structure. j

In addition to the above the following may be pointed out: The size in width of an average double-edged razor blade is about seven eighths of an inch; the reason for such a size is that the average razor head, for holding a double-edged razor blade, is so built that it requires a razor blade of such a size in width. Whereas the structure of my invention is of such a type that the razor-head, in actual size, can be made to hold a double-edged razor blade of only one quarter (1A) of an inch in width.

It must be remembered, that a razor blade is used several times and then discarded, so that the material comprising such a razor blade becomes a completely useless Waste. Razor blades are made in the millions annually. A comparison will clearly show that the amount of material necessary to manufacture two (2) millions of the ordinary double-edged razor blades for `use in connection with the present type ordinary razors would be suliicient to produce seven (7) millions double-edged blades for use in combination with the razor head made in accordance with my invention. Such a tremendous savingof razor blade material, annually, is of such great importance to razor blade manufacturer that this in itself would cause my invention, which would be instrumental in procuring such tremendous annual saving of material, to be of great commercial value to the razor manufacturer.

There is, therefore, thus produced in accordance with my invention, an injector razor comprising a head structure adapted for use in combination with a razor blade of considerable narrow width having two individual opposite cutting edges, wherein each side-comb-portion of the head structure in combination with its respective cutting edge of the double-edged razor blade is adapted to shave without changing the position of the blade upon its seat, and wherein the head structure permits slidable movement of a double-edged razor blade upon its seat upon yieldable frictional engagement without injuring the cutting edges, and wherein the head structure is provided with a corrugated slot of a shape tapered downwardly to a narrower size than that of its upper section, to receive a magazine linger of similar shape cross-sectionally for readily operating the upper portions of the head structure to receive or eject a double-edged razor blade, thereby providing the user of an injector razor with a magazinefeeding shaving implement having two cutting edges for quick and satisfactory shaving purposes.

Thus, a shaving implement made in accordance with my invention, comprises a properly constructed razorhead, and a removable blade magazine, each built in a practical manner to cooperate with each other; such shaving implement comprising a practical long sought for double-edge magazine razor affording a maximum of shaving surface not obtained heretofore by an injector razor; and therefore provides fast and superb shaving performances, great satisfaction and comfort to the user. It is believed that such a shaving-implement can be utilized to great advantage and therefore prove quite valuable commercially.

The variety of possible application of my novel construction with different types of razors, as herein above indicated, is so prolific that for the purpose of illustrating the invention the specic embodiment of my invention in its application to a shaving-implement exhibiting the greatest diculties has been selected. Such a shavingimplement is one which necessarily must conform most rigidly to the contours of the portion to be shaved and one which has the eld of greatest possible commercial use. For this purpose I have selected for illustration of my novel construction, a shaving implement constituting a magazine feeding type razor, so that the principles of construction may be best illustrated in a razor known as a magazine razor or shaving implement.

The objects of the present invention are attained by a novel construction which will be hereinafter described and illustrated in the drawing in connection with a specific embodiment of the invention.

Referring more particularly to the drawings, in which similar reference characters identify similar parts in the several views, in my novel shaving-implement.

Arrow A indicates a razor head structure, usually known as a razor. 10 indicates the outer member and 11 indicates the inner member. The inner member 11 comprises a wall portion 12 and a platform 14. This platform 14 is adapted to form a seat for a razor blade 1S. The wall portion 12 is provided with a slot 16 so formed that when the platform 14 is bent upon its curvature 17 the blank 18, from the slot 16, is lifted simultaneously upwardly in line with the platform 14 forming a continuation thereof. The longitudinal front end portion of the blank 18 and the opposite longitudinal end portion 19 are each curved downwardly to form comb or guard sections 21. The platform portions adjacent the comb sections 21 are each provided with the usual slots or openings 22.

The outer member 10 is provided with a wall section 24 having outwardly extending end sections 25. These end sections 25 are shaped or bent into outwardly lz-ulfred curved sections as at 26 forming inwardly disposed flange portions 27 and 27'. These

flange portions

27 and 27 are carrying between them a blank element or cover element 28, for a purpose which will be hereinafter explained.

The wall section 24 is provided with inwardly disposed

wall portions

29 and 30. The wall portion 30 is provided with a zg-zagged or corrugatedly shaped slot 31 which is of a shape tapered, gradually, downwardly to a narrower size as shown at arrow B than that of its upper section indicated by arrow C.

The end portions 12' of the wall 12 are shaped or bent inwardly in a manner, for example, as indicated by arrows D, and are positioned against the inner faces of the

wall portions

29 and 30. This wall portion 12 is also provided with hook elements 32 and with an extension 12".

The outer member 10 is provided with a handle 35 secured thereto by rivets or screw elements This handle 35 is provided with a screw-threaded opening 37 and with a recess or groove 38.

My shaving implement may be assembled in the following manner; the hooks 32 are placed, in a hingeable manner, within the openings 33 thereby connecting the inner member and outer member to each other. The spring 39 is then placed into proper position, having its extension 44 placed within the recess or groove 38. The screw element 40 is then placed, loosely, within an opening in the spring 39 (opening not shown) and then in a rotatable manner into the screw-threaded opening 37 having the shoulder, of its knurled head 41, force the spring 39 towards the member 11 to an extent whereby the bulged portion 42 presses the inner member 11 towards eea-4,2m

Yopening or slot 45 and form a support for the cutting edge 84 of the razor blade 15 for shaving purposes; so that this comb or guard section 18 and the comb or guard section 19, which is adapted to support the cutting edge 81, form the support for the two cutting edges of a double-edged razor blade 15. Naturally, when the razor blade 15 is positioned upon the platform 14, the tension of the spring 39 pressing and forcing the platform 14 upwardly will hold such blade 15, frictionally secured, upon its seat between such platform 14 and the roof or cover 28.

Arrow E indicates a razor blade magazine carrying a stack of razor blades 15, supported by a spring 51 which is secured to the floor 52 by suitable means, for example, rivets or screw elements 53. The front wall 54, is provided with an outlet slot 55, having enlarged end openings 56 to prevent marring of the cutting edges of the razor blades 15, while such blades are being fed from the magazine into the razor head. 'The front wall 54 is provided with aV zig-zagged or corrngatedly shaped element or fin ger 57 of a style tapered, gradually, downwardly to a narrower size as shown at arrow Ba than that of its upper section indicated by arrow Ca, of a size titing slidably into the slot 31.

The inner face 58 of the frontv wall 54 and the inner face 59 of the rear wall 6i?, of the magazine arrow E, arc each provided with extensions 61 adapted to fit within the end portions of the slots 62 of the blade 15, thereby holding the stack of blades 15 in desired position within the magazine without marrin'g their cutting edges. The upper portions of the side walls 63 and 64 are each provided with a slot 65. A iiat shaped feeder 66 is positioned within such slots 65 having the end portions thereof bent upwardly and over the top wall 67, as at 68, forming gripping means 69.

When it is desired to feed a razor blade from the maga- Zine into the razor head; the magazine nger 57 should be placed into the finger slot 31, the frontportion 71 of the finger 57 will enter the space 72 and slide into position between the members and 11, separating these two members from each other, 'for example, in a manner as shown in Fig. 2. The upper end portion 73 of the ringer 57 will, slidably, engage the projection or shoulder portion 74 of the member 10, and the lower portion 75 will engage, slidably, the extension 12 thereby moving the inner member 11 downwardly separating the front-portion 76 of the platform 14 from the front portion 77 of the roof or cap 28, thus providing space for the blade to enter the seat'space 78. By moving the feeder 66 towards the outlet slot 55 the uppermost blade 15 will be moved into desired position within the razor head, for example, asl

shown in Figs. 3 and 15, and when the linger 57 is withdrawn from the slot 31 the inner member 11 will, by pressure of the spring 39, be forced towards the outer member 10, bringing the extensions'79 in direct engagement with the end portions of the cutting edge 81, as at 32, and will also bring the inner faces S3 of the bulged, curve or bent portions 26 in direct engagement with the end portions of the cutting edge 84, as at 85, and permit yieldable pressure thereon and also of the platform 14 against the blade 15, forcing same upwardly against the roof or cap portion 28, thus holding the blade 15 in a locked position for shaving purposes. The rear end p0rtions of the platform 14 and roof or cap 28 are tapered as shown at arrow F to facilitate the opening and closing operation of the front portions of such members.

It can be seen that turning the knurled head 41 into desired direction the tension of the spring member 39 will be increased, whereas turning such knurled head 41 into opposite direction will reduce the tension of the spring member 39, thereby adjusting the pressure ofthe spring member 39 against the inner member 11 to desired degree; whereas `thhe complete removal of the screw element 40 from the screw-threaded opening'37 will separate the parts of the structure from each other for cleaning purposes. it will thus be seen thatV the knurled-head screw structure performs several functions; namely, holding the parts in assembled form for shaving purposes, adjusting the spring tension to desired degree, and separating the parts for cleaning purposes. The extension 44 being positioned within the slot 38 prevents rotatable movements of the spring member 39 thereby holding the bulged p0rtions 42 and 43 in desired position. Of course, the disclosures herein are for illustrative purposes only and not for limitations; for example, if desired the screw-threaded member 40 may be eliminated and a rivet may be used instead in a manner holding the parts permanently together, or various other changes in form of structure may be resorted to without departing from the spirit of this invention.

For clarification purposes the following may be pointed out. While the ordinary type of razor blades may be made to be used in connection with my injector razor, yet, for the purposeof providing means whereby a superb shave may be obtained, I provide my razor blade 15 with a new kind of cutting edge; I over-grind the longitudinal upper end portion of the cutting section and form a convexed shape as shown at 91, and then I under-grind the underface of the razor blade as shown at 92, thereby forming an angled keen sharp cutting edge 9.3. It is believed that such angled cutting edge will afford a more satisfactory shave than may be obtained from the ordinary type of cutting edge. The thickness of the blade in the illustrations has been greatly exaggerated to show clearly the construction or shape of my new cutting edge.

I desire it to be understood that the disclosures herein are for illustrative purposes only and not for limitation purposes. My injector razor, and magazine, may be made of various suitable materials, the parts may be made in any desirable manner, for example, machined, stamped, molded, pressed, extruded, or die-casted, and be made in any suitable style, size or shape.

From the above it will be evident that my invention, hereinabove illustrated and described, teaches an entirely new principle in the art of shaving-implement construction. The novel manner, or form, of my injector razorhead structure, the two comb sections for supporting the two cutting edges of a double-edged razor blade, and the roof portion thereover and the adjustability of same with respect to each other, the yieldable engaging means of the head-structure for frictionally engaging the doubleedged razor blade during its slidable movement while being fed from the blade magazine into such head structure, the means for holding such double-edged razor blade in locked position for shaving purposes, the adjustable tensioning means, the simplicity of taking the sections apart for cleaning purposes and for reassembling same, the novel slot and key structure, are important and useful features. It will therefore be seen that the structure herein illustrated and described is of a novel patentable nature, practical, it can be utilized togreat advantage by the user, and is therefore believed to be of commercial Value.

From the above it will be seen that I have invented and perfected a shaving-implement comprising an injector razor of a new and unique design and structure, an injector razor which is practical, useful and therefore of commercial value, and although I have shown certain preferred forms or illustrations in order to explain Vand describe the novelty of my invention, yet, by showing such structure, I do not, by any means, limit myself to these structures, nor to the terms used in describing same, as they are for illustrative purposes only. Various suggestions and changes of structure may be resorted to, and I desire it to be understood that I have same in mind when showing and describing this invention, and seek protection by Letters Patent. And, although I have mentioned in describing this invention of what material certain parts may be made, how they may be formed, shaped or styled and how they may be assembled, yet I desire it to be understood that this structure, or parts thereof, may be made of any suitable material, and shaped, formed, styled or arranged in any desirable manner, and assembled in any convenient way so that the parts may be easily taken apart, removed, cleaned, replaced and reassembled, and that various changes in detail may be resorted to without departing from the spirit of this invention.
