REPEATING SAFETY RAZOR Filed Jan. 18, 1946 Patented Aug. 7, 1951 "umreo STA PATENT "OFFICE REPEATING SAFETY'RZAZOR Ralph iGp A-rey, Swampscott, Mass.
:Application L'January 18, 1946, 'SerialNo. 41384 3 .Claims.
My presentinven'ti'on is a novel and improved safety razor, wherein a plurality ofblades-canbe successively and quickly brought into operative position and "as quickly and readily removed to permit a succeeding blade to be so positioned.
Hereto'fore in the construction of razors of'th'e magazine or repeating type, wherein successive blades "were fed, pushed, or slid into receiving 'tacts.
My present invention obviates the difficulties heretofore experienced in this class of safety razor and provides a relatively large number of new blades, with'each blade protected from damage, injury, or drilling contact-of its cutting edge, and yet is readily and quickly positioned for the shaving operation.
An important feature of 'my present invention is the novel construction of a blade-holding,
--;protecting, and -carrying element whereby a large number of blades such as sixty or more,
can be assembled in a relatively small and "compact roll-or cartridge for refilling, wherein-each blade is protected 'against'rust, injury, or dulling contact of its cutting edge with other blades or any portion of the razor construction and, there- "fore, is maintained in sharp and perfect condition for use.
This carrier element is, preferably, a "flexible waterproof strip and, preferably "also, "has "one surface prepared, coated, or otherwise treated to give a pressure-adherent feature so "that the blades may be positioned thereon and held many desired alignment/but will "be quickly freed from the carrier strip whenth'e blade has been moved into shaving position; whereupon that part of the carrier striputilized therefor can be torn off, freeing the surface of the blade.
I may employ any suitable flexible element as the carrier, such as paper, a thin textile, ='or fibrous strip, as well as a film of syntheticp'lastic. Any of these elements *can'be provided with a pressure-adherent surface on which the blades can be laid in alignment and insp'aced position;
whereupon the carrier and blades are formed into a compact package, such as a roll, which :1 have defined as a cartridge, for filling and refilling the razor o'f'my present novel construction. By having the series of blades relatively thin and narrow and the flexible carrier strip with a pressure-"a'dh'ere'nt "surface, -'a "large number of such blades "can he la id upon the pressure-adherent sur'f'ac'einpredetermined spaced relation andyet relatively close together; and thereupon the can rier rolled or folded into cylindrical or package "form, thus covering and rotecting "each of the blades'while still maintaining them enclosed and free of damage or dulling contact ''-With :themselves or other metal, and "in a dispensingposition ready for use. In place of rolling, the carrier "and its attached blade may be folded or otherwise assembled to protect the "blades in on- "closing and non-dulling contact.
Thus I provide "a magazine :or cartridge witha rlatively' large number of blades for the repeating "operation, all of which blades 'are protected from rust, damage, injury, or 'dulling contact withanymetal and 'yet are ready instantly to' be drawn into operative shaving position by the unwindingor unfolding of the "flexible carrier. cutting edge of each blade is thus perfectly protected until it is in operative shaving position in the "razor adjacent -'a safety guard and Iother holding instrumentalities.
My *novel razor construction for handling and utilizing "such a magazine carrier with repeating razor blades is of simple, eflicient, "and attractive appearance and cohstrutztioh, and without any objectionable weight, "attachment, or bulky handle such as certain prior types of repeater razor constructions wherein the blades are assembled in the handle.
"My novel razor construction comprisesa handle and "ahead, the latter having a suitable recess to receive and hold the carrier, as :a magazine, package, orcartridge containing the razor blades rolled, folded, or enclosed in their protecting carrier. The operative edge portion of the razor "may include a typical type of safety guard adjacent which the successive razor blades are fed, fitted, positionedand held. I prefer to form a movable, such as a hinged-top element which can he raised to facilitate fitting ina new cartridge or package when refilling the razor; and thereupon can be closed on top- 0f the carrier with the attached blade, which is fedin'to operative position by pulling the carrier Strip the :short space required between the successive blades thereon.
Each blade can be readily held in :fixed operative position by any suitable means, such for "ex- .eampl'e @as an edge guide and dowel pins fitting :into corresponding recesses at the edges of the 55 blade :or at any pointremote from the "cutting edge, the top being raised and lowered to facilitate this action, if necessary. After the shaving operation and in order to remove the used blade or position a new blade, the top can be lifted and the carrier pulled forward, the old used blade being displaced and removed while a new blade is brought into position.
Further advantageous features, novelties, combinations, and advantages will be hereinafter more fully pointed out and claimed.
Referring to the drawings illustrating a preferred embodiment of my present invention:
Fig. 1 is a side view with the head partly in cross-section illustrating my present novel safety razor and protecting and repeatingblade-holding construction;
Fig. 2 is a perspective view showing the unwrap ping of the carrier and a fragmentary portion of the safety guard, blade-holding means; :and'. a portion of the top;
Fig. 3is a plan view of my repeater blade;
Fig. .4 is a fragmentary diagrammatic view showing a spring clip to hold the top and guard portions together to lock-the blade inoperative position;
of other desired shape and contour, but is herein, 1
shown as. rounded at one end and extending to a curved flange 2 at the opposite end, to which flange a semi-cylindrical bottom portion3 is weldecl or otherwise secured. This member 3 has an angularly positioned safety guard lending in the usual type of curved projections 5 and constituting the guarding; element 7 during the shaving operation. r I
On the. opposite side of the cylindrical element 3 is pivoted at 6 a top or cover l which has its forward portion l2 of sufiicient length and size to extend in parallelism with the guard 4, as clearly shown in Fig. 1. The cover I2 can be easily lifted for refilling as well'as for feeding forward a new blade when discarding a prior blade.
Preferably the hinge 6 is normally a yielding connection to tend to spring the cover l0 and forward part I 2 into position; but in order to hold the same in rigid position on the guard 4, I provide a suitable latch or look as shown in enlarged perspective and fragmentary form in Fig.
4. Such a spring lock may comprise a clip I 4 pivoted at i to lugs It in the bottom of the guard 4. This spring clip I4 may be held in looking engagement with the .top 12 by fitting in the groov I! or in any similar suitable manner.
.My noveltype of flexible carrier is indicated as a strip 2i and is preferably coated on one side with a pressure-adherent adhesive 2!) across which, in spaced relation, are laid the series of blades 25- which are thereupon assembled in a roll, magazine, package, or cartridge 26. These blades are'positioned so that thecutting edge 38 of each will be in forward position during the unwinding of the carrier and the positioning and feeding of each blade into operative position adjacent the guard.
With the razor blades assembled and rolled into cylindrical protecting and carrying form, they are thus maintained in moisture-proof condition,
view of the carrier and v as well as having the edges protected against any dulling contact and are still ready for instant feeding into operative position. The carrier strip 2| readily unrolls in its position between the semi-cylindrical base 3 and the top l0 and is led forwardly, carrying a blade 26 with it, with the edge 30 in foremost position until adjacent the guard.
In order to insure the correct alignment and positioning of the blade, I'provide a flanged guide 3| on each edge of the guard adjacent the end and also aligning dowels or pins 33 which will register with corresponding recesses 34 in each end portion of each blade back of the cutting edge. The carrier 2| being fed forward with the blade in position with the recesses 34 over the dowels 33 will then be forced downwardly in locking engagement with the dowels by the closing of the cover [2, and the cover l2 and guard 4 are then looked in position by the spring clip [4 which is swung upwardly on its pivot and locked in the groove [1, thus exerting a spring tension on the guard and top as well as on the blade and holding same during .the shaving operation Thereupon the surface stripof the carrier 2l between the preceding blade, which is removed, and the succeeding orrepeating blade, which has now been moved into position, permits the end portion of the. carrier to be torn off by pulling it upwardly against the end of thetop I2, which may be formed as a tearing edge for this purpose.
After one blade v26 has been used and it is desired to discard the same and position a new blade, the clip M is snapped from looking position, the cover I2 lifted, the blade 26 raisedfrom engagement with the dowels 33, and the carrier strip pulled forward, rotating the magazine or cylindrical part of the head of the razoruntil a new blade is in position, being guided by the flanges 3| and fitted over the dowels 33, whereupon the cover I 2 is; closed, the clip I4 sprung upwardly and the surplus marginal portion of the carrier 2| torn off, and the razor is ready for use with a new blade. 7 1
Referring to Fig. 6, wherein I have illustrated a modified form of carrier, herein shown partly in perspective and in diagrammatic form, the carrier element 40, while preferably of flexible or pliable material similar to the carrier 20 above described, is not necessarily the same as long as the carrier can be folded into a series of carrying. and protecting leaves, havingthe blades 25 adhesively attached to one surface and capable of readily dispensing the successive blades 25 as the carrier 40 is drawn to operative position adjacent the guard 5.
For this purpose, the'carrier 4D is folded approximately along the dotted lines, as indicated at 4 lll, forming the series of leaves or sections whichenable the carrier to be folded into compact form for fitting within the razor. If this foldedform of protecting and dispensing carrier is employed, the head would not necessarily be in the curved contour as shown at 3, Fig. 1, although such folded construction could be appropriately fitted therein without difficulty and the dispensing portion led downwardly between the guard 5 and cover ID, as therein illustrated. In utilizing the folded carrier, while it is preferably in the form of a'strip, the carrier might be in sections or segments with one or more blades which could be readily assembled in stacked relationand separately and successively dispensed to the operative position of the razor at the guard portion. While I prefer to use a presportance.
sure-adhesive strip to retain the blades in protecting and dispensing position, it will be appreciated that any other suitable detachable blade-holding means may be employed to permit the blade to be readily separated from the carrier When the blade has been carried to operative position adjacent the guard of the razor. This feature of having the blades on the carrier, particularly where relatively narrow thin blades are employed, as in my present construction, and with the blades still attached to the carrier when moved into razor-shaving relation is of great im- It is also of importance to permit the used blade, with its attached and adjacent portion of the carrier, to be simultaneously removed, detached, or broken off when a new and successive blade is to be utilized. Furthermore, my invention of a carrier and blade construction comprises the novel means of removing a used blade and the attached portion of the carrier at a line or position which will free the cutting edge of the succeeding blade from immediate attachment to its adjacent portion of the carrier, thus presenting an entirely new, serviceable, sharpcutting edge while the rest of the new blade and the succeeding blades are still attached to the carrier. Preferably, also, I position the carrier on the top or upper side of the blades, thus attaching and feeding the attached blades underneath the carrier directly into a locking position with the razor, whereby the cutting edge of a blade is presented for a downward cutting stroke with the attached portion of the carrier on the top or upper surface.
These features are believed to be a distinct novelty in this art and I wish to claim the same herein broadly.
One of the important features of my invention is the large capacity of the blade-carrying element. While I have shown herein for illustrative purposes a relatively few blades in the roll 26, yet it will be appreciated that by having such an enclosing, protecting, and dispensing construction as herein illustrated, a very large number of blades can be rolled in the magazine or cartridge 25, the capacity of such a roll with thin narrow blades is easily sixty or more.
It will thus be seen that I have devised a novel and improved safety razor construction with a magazine, storage, package or repeating bladeholding element of suitable flexible material, which also protects all the blades in the magazine during storage, transportation, or while in the razor head, maintaining the cutting edge in perfect condition until actually positioned in the operative part of the razor, without dangerous handling by the user, and by a simple, quick, and expedient operation.
My novel blade-carrying element is believed to be a distinct novelty in this art, and I wish to claim the same herein broadly, as well also as the process of enclosing, folding, or rolling the plurality of blades in a package or magazine form for filling and refilling my novel razor.
1. Improved safety razor construction of the kind described, comprising a handle, a holder for a plurality of individual blades, a flexible carrier having a pressure-adherent surface for said blades, and means automatically guiding an individual blade into operative position by the unro11ing of the blade-holding carrier, during the removal of a used blade.
2. A repeating safety razor of the kind described adapted to receive a plurality of blades enclosed in an interrolled flexible carrier, said carrier having a pressure-adherent surface, on which surface the blades are detachably secured in spaced relation, a guard carried by the razor to hold successive blades in operative position, and means to feed, guide, and lock said blade successively adjacent said guard during the unrolling of the interrolled carrier,
3. A cylindrical interrolled magazine constructed and arranged to carry a plurality of blades and to be fitted in a razor holder formed with a recess to receive said cylindrical magazine, said magazine consisting in a flexible blade-carrying strip, with said plurality of blades adhesively secured to said strip and protected by the interrolled cylindrical form, the unrolling of the strip bringing successive blades into position for use.
