MAGAZINE SHAVING IMPLEMENT Filed Feb. '4, 1952 United Stats atent O F MAGAZINE SI-IAVING EMPLEMENT Jacob L. Kleinman, Arverne, N. Y. Application February 4, 1952, Serial No. 269,782
11 Claims. (CI. 30-40) This invention relates to the construction of shaving implements in general and more particularly to a type known as a magazine 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.
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 a double cutting edge.
In accordance with my invention, I produce a shaving implement comprising a razor head having a seat for holding a razor blade having two cutting edges wherein the guard sections are adjustable with respect to said seat and such cutting edges, and wherein the head structure is provided with adjustable means for flexing the blade upon its seat to tilt the cuttnig edges into desired position for shaving purposes, and with means norm?l1y blocking the removal of the blade from its seat or the insertion of a succeeding blade and with a wall portion having a zig-zag or corrugatedly shaped slot for a finger of similar shape to be inserted therethrough into the interior of the razor head to move the guard sections away from the seat and from the cutting edges of the blade and to move the blocking means into a non-blocking position permitting the removal of the blade from its seat or the insertion of a succeeding blade, and upon the retraction of such finger from the slot the blocking means will revert back to its normal locking position and the guard sections will adjust their positions with respect to the cutting edges of the blade.
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 utilized to great advantage; it is a well known fact that the head structure of the present type injector razor comprises two separate members, one having a seat for the blade and the other forming a. blade cover, so that when a magazine finger isplaced within the space between these two members, these members will flex away from each other moving the cover away from the seat for placing a blade upon the seat, but instead of a magazine finger, a screw driver, nail or the like can easily be placed within the space between these two members, moving the cover away from the seat so that a foreign blade can be inserted by hand into the head structure without the use of a blade magazine feeder, especially so when the razor head is not provided with blocking means to prevent such blade insertion. Such foreign blades are usually constructed in a defective manner and of inferior quality, and are known as bootleg blades; they do not function in a satisfactory manner and are apt to bring about hazardous after shaving effect. The average shaver is an ordinary layman who does not know the manner in which razor blades are constructed and cannot judge blade quality, and therefore buys such defective blades ignorant of the danger involved especially when a quick ward position that is, while the projecting corrugated 2,821,779 Patented Feb. 4, 1958 shave is desired. It is an object of the present invention to protect such inexperienced layman and shield him against possibleshaving injuries by preventing the use of such inferior and defective blades. It can therefore be seen that a shaving implement constructed in accordance with my invention will prevent the use of defective blades and will therefore eliminate the hereinbefore mentioned features and protect the user against hazardous shaving effects, and instead such user will derive the full benefit of superb shaving performance, especially so because applicants structure provides a double edge magazine injector razor using a double edge blade, thus providing the user with a maximum of shaving comfort to an extent whereby such shaving implement would become an indispensible item with the user and therefore quite valuable to the trade commercially.
There is, therefore, thus produced, in accordance with my invention, a shaving implement comprising a head structure for using a blade having two cutting edges, wherein said structure is provided with means normally blocking the removal of the blade from its seat or the insertion of a succeeding blade, thus eliminating the use of foreign blades, protecting the user against persuasion to buy blades which may be made of inferior material or constructed in a defective manner, and guarding the user against possible injuries or hazardous after shaving effects, and wherein the cutting edges of the blade are shielded against injuries while such blade is being moved from the magazine into the razor head thereby affording the user double means for quick and satisfactory shaving.
Thus, a shaving implement made in accordance with my invention comprises a properly constructed razor head and a removable blade magazine built in a practical manner, such shaving implement affording a long sought for superb shaving pzrformance. It can be used with considerable ease and provides 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 applications of my novel construction with different types of razors, as hereinabove indicated, is so prolific that for the purpose of illustrating the invention the specific embodiment of my invention in its application to a shaving implement exhibiting the greatest difiiculties has been selected. Such a shaving implement is one which necessarily must conform most rigidly to the contours of the portion to be shaved and one which has the field of gre"test possible commercial use. For this purpose I have selected for illustrationa shaving implement constituting a magazine feeding type razor so that the principles of construction may best be illustrated in a razor known as a magazine razor or shaving implement.

Referring to Fig. l", numeral arrow indicates a razor head having a top or cap 21 for covering the upper part of'a razor blade, the razor head being adapted for housing' a double edged razor blade. The front wall 22 of the'razor'has a projecting member 23 which is adapted to fit' within the recessed portion 24 formed in the front wall- 25 of the magazine 26. Wall 22 of the razor is'provided with a horizontally formed zig-zag or corrugatedly shaped slot 27 located in any suitable position, for example, beneath the projecting member 23' for receiving a corrugatedly shaped finger 28 of the magazine 26. Directly above the sloping top 29 of the projecting member' 23 there is a horizontal slot 30 to permit entrance within the razor of' the uppermost blade of the magazine 26'. The cap 21 of the razor is arcuately formed toperrnit the flexing of the blade 63 within the head'structure of therazorwhen such blade 63 is forced upwardly by the shoulder portions 74 of the centralizing member 46; Within the head structure of therazor there isa platform' 32' having" an under face 32' and an upper face 32", said" upperface32" forming a seat upon which th'eblade is seated. On either side of the platform". 32 there is a pair of opposed guards 33 which are caused to. move in; opposite lateral directions with respect to the seat 32" whenthe corrugated finger 28-is. inserted within the corrugated. slot 27. At opposed ends of the guards 33 there are stops 34 to engage the end portions of the cutting edges of the razor blade within the razor. Secured. within the front and rear of the razor there are centrally disposed opposed spring members 35 positionedv along. the longitudinal medial line of the razor, the said springs. 35 protruding upward through the slots 36 of the platform. The end portion 37 of the spring 35 rests against the underside of the platform. 32, thus controlling the upward movement of. the spring. Guards 33 are formed with depending legs 38 and have openings 39 at the lower ends thereof for receiving pivot pins 40. The platform 32-has two pairs. of opposed slots 41 for guiding the upper portions 42 of the guards. In order to hold the: guards in their normal position,v two pairs of opposed springs 43 are-provided, the: said. springs being; attached to. the inside 05 the side walls 44 of the razor 2D. The. platform 32:
is also provided with a slot 45 located centrally along the longitudinal medial lineof therazor to permit'tho blade centralizing member 46 to pass therethrough.
Referring to the magazine structure, this magazine is adapted to house double edged blades and has a top 47 having two longitudinal opposed slots 48 within which a pair of feeding members 49 move. Attached to the top of feeding members 49 there. is a fingerpiece 50 which moves alongthetop47 andhasdepending opposed flanges 51 for guiding the fingerpiece and the feeding members on the magazine. The front wallv 25 is recessed and has a horizontally disposed slot 52 directly beneath the top 47 to permit the uppermost blade to pass from the magazine to the razor. Projecting from the bottom 53 there is a horizontal corrugated finger 28 and beneath the longitudinal medial portion of the top 47 there is a groove 54 within which is positioned a pair of spring elements 55 which are adapted to be positioned within the longitudinal slots 56 of the blades of the stack of razor blades within the magazine so that the blades cannot shift laterally, thus preserving the cutting edges of the blade during movement of the blade at the time it is being ejected. A spring member 57 is attached to the bottom 58 of the magazine which creates a forward pressure upon the stack of blades so that the uppermost blade is always in position to be ejected from the front of the slot.
In the magazine there is a rear wall 59 which is spaced inwardly from the rear edge 60 of the magazine so that there is ample. space for the feeding members 49 and the fingerpiece 50 to move behind the stack of blades within the magazinein order to permit the feeding members 49 to engage the rear edges of the uppermost blade for the purpose of ejecting such blade. The rear wall 59 has a vertical ridge 61 running up to just below* the uppermost blade in the magazine for aiding in the alignment of the stack of blades to prevent lateral movement of the stack of blades, thus ensuring against marring of the cutting edges. The front wall 25 has a similarvertical ridge 62 of suflicient height to act for the same purpose upon the front of' the stack of blades as the ridge 61.
By inserting the corrugatedly shaped finger 28 within the slot 27, the projecting member 23 will fit within therecessed portion 24, thus aligning the slot 52 of the magazine with the slot 30 of the razor, thus preventing lateral movement of the magazine and ensuring perfect alignment of the slot. and thereby permitting the uppermost blade to move freely into the razor without any danger of marring the cutting edges of the blade. The sloping top' portion 29 of the projecting member 23 guides the front edge of the uppermost blade into the slot 30' of'the razor. During the ejection of the uppermost blade from the magazine, the spring members 55 guide the uppermost blade against lateral movement and when the. front of the blade enters the slot 30 of the razor, the spring 35 falls within the front slot 56' of the blade so that it. is also. guided within. the, razor and ensures against. lateral. movement of the blade, thus. eliminating any danger of marring the cutting edges. During the ejection. of the. uppermost blade from the. magazine, the spring members 55 are lifted from the leading slot. 56 and ride over the bridges. 63 of the blade and thensprings 55 fall into thelsucceeding openings 56" of the blade. It should be noted that the front and rear slots of the blade have tapered corners 64 so that when the leading; edge of the blade enters the razor through slot 30, the tapered corners. 64 will locate the adajacent spring 35 which will guide and position thethe finger 28 will engage the opposed curved portions 66 of the legs 38 and force the legs 38 and guard 33 outwardly away from the seat and from each other,"thus releasing the blade 65 from the grip of the stops 34. When the finger 28 is completely within the razor, the fingerpiece St) is then moved towards the razor, ejecting the uppermost blade from the magazine and injecting the new blade into the razor head and while this action is taking place, the used blade 65 is simultaneously ejected by such incoming blade. This form of structure assures proper relation of the cutting edges of the blade 65 with respect to the front edges of the guards 33. The fact may be pointed out (for explanatory purposes) that the cross-sectional width of razor blades are not all of the same size, they dilfer in size for various reasons, for example, a long strip of razor steel can not be uniformly hardened, while being heat-treated, throughout its full length; the blades of such strip of steel are therefore not all of the same spring temper, so that during the grinding process more steel may be removed from the edges of the blade which is of a weaker springtemper than that of the blade which is of a stronger spring-temper, thus a blade of a weaker spring-temper may be of a lesser size in width cross-sectionally than the cross-sectional width of a blade of a stronger springtemper. It can therefore be seen that my movable guard portions 33 which are movable independently of the blade seat and are provided with stops 34 for engaging the end portions of the cutting edges of the blade 65 are a very important contribution to the art of making razors or razor blade holders. The stops 34 will always hold the front edges of the guards 33 in proper relation with respect to the cutting edges of the blade 65 regardless of the size of the cross-sectional width of the blade.
The member or movable element 70 (which is positioned underneath the under face 32' of the platform 32) is provided with upwardly projecting portions 70'. These upwardly projecting portions 70', when in normal shaving position, block the removal of a blade from the head structure or the insertion of a blade into the head structure. When the corrugated finger 28 is being inserted into the head structure through the space, slot or opening 27 the leading edge of such finger will, while being moved inwardly, engage the lower portion 67 of the lever 68 and cause such lever 68 to pivot about the pivot, element or pin 69 and draw the movable element or member 70 with its upwardly projecting portions 70 downwardly, thereby clearing the front slots 30 and 30; and, simultaneously therewith, pivoting the opposed lever 71 which in turn will draw downwardly the blade centralizing member 46, thereby removing the uppermost end portion of such member 64 from the slot 56 of the blade 63, thus clearing such slot 56 and permitting the removal of the blade 63 from the head structure of the razor or the insertion of a blade within such head structure, and upon the removing of the finger 28, the spring elements 72 and 73, the upper ends of which press upon the end portion 67 of the levers 68 and 71, will cause the upper portions of the said levers to rise and carry with them the movable element and its slot closing portions 70' and also the blade centralizing member 46 to their uppermost position, in which case the end portions 70 will pass the platform or seat 32 and also the blade thereon until they reach the cap structure 21, and the upper portion of the centralizing member 46 will enter the opening 56 of the blade 63 holding such blade centrally located within the head structure of the razor. thus effectively closing the slots 30 and 30' and also flexing the blade within the razor by the shoulders 74 of the member 46 engaging and pressing upwardly the bridge portions 63 of the blade 63, thereby flexing the blade to the desired position shown in Fig. 3.
The tension and the flexing of the blade within the razor can be adjusted to the desired curvature and positioning of the cutting edges by turning or rotating the screw 75 which holds the terminal orspring' 72. It should be noted'that the nut 76 is held by the inside face of one of the walls 44 against rotation so that nut 76 will travel up or down by the turning of the screw 75, thus adjusting the tension of the spring.
The screw 75 is provided with a shoulder 77 and is inserted through the large opening 78 of the slot 79 and is then moved into position in the portion 80 against the wall 44 and is held against movement by the terminal loop of spring 72.
It is naturally understood that the disclosures herein are for illustrative purposes only and not for limitation purposes, it is therefore obvious that various changes and modifications may be made in the details of construction and arrangement of parts without departing from the general spirit of the invention.
