Application July 22, 1941, Serial No. 403,483 a 4 Claims.

My invention relates to a combined, or unitary. razor blade magazine and razor blade magazine holder and refers particularly to devices of the described character adapted for the removal of razor blades from razor head elements and for depositing razor blades thereon, these results be- 7 ing obtained simultaneously, or independently, of each other. l

One object of my invention are devices adapted to remove blades from safety razors and deposit blades thereon without contact between the blades and the hand of the operator.

Another object of my invention is a unitary construction adapted to carry a plurality of razor blades with means for allowing the withdrawal of a single blade therefrom while retaining the remainder of the blades within the device.

Another object of my invention is a unitary device adapted to carry a plurality of razor blades with means for allowing the withdrawal of a single blade therefrom while retaining the remainder of the blades within the device and means adapted to co-operate with razor heads to allow of the removal of a blade therefrom.

Another object of my invention is a unitary device adapted to carry a plurality of razor blades with means for allowing the withdrawal of a single blade therefrom while retaining the remainder of the blades therein and means adapted to co-operate with razor heads to allow of the deposit of a blade thereon.

The above, and other, new and valuable attributes of the devices of my invention, will be evident upon a consideration of my specification and its accompanying drawing.

Safety razors have been suggested from which properly positioned blades are practically imlow of the withdrawal of a previously deposited blade during said longitudinal movements, ii desired.

In the accompanying drawing, illustrating one form of the devices of my invention, similar parts are designated by similar numerals.

possible of removal without the assistance of special devices, the successful operation of which is dependent upon their special construction in consideration of the construction of the razor with which they are to co-operate.

The devices of my invention are of unitary construction and comprise a blade magazine adapted to contain a plurality of stacked razor blades, allowing the withdrawal of a single blade therefrom whileretaining the remainder of the blades within the magazine, in combination with a blade magazine holder adapted to guide my devices in longitudinal movement over the face of a razor head element and to allow blade withdrawal means of said razor head element to withdraw a single blade from said magazine and deposit it upon said razor head element during Figure 4 is an enlarged section through the line 4-4 of Figure l. I

Figure 5 is a section through the line 5-5 of Figure 4, the position of a razor head element in co-operating position with my device being indicated in dot-and-dash lines.

Figure 6 is a top plan view of the spring element of my device.

Figure '7 is a top plan view of a razor blade adapted for use with my described device.

The particular form of a combined razor blade magazine and razor blade magazine holder of my invention illustrated in the accompanying drawing comprises a casing having a top member Iii,

which is extended forwardly into the two spaced inclined blade guide members H, H, two side members each having a vertical member H, which is extended outwardly and downwardly forming a curved guide member 13, and thence inwardly forming a bottom member M, the two bottom members, thus formed, being spaced longitudinally of each other, and an end member ii. The ioreward end portions i6, J6 of the side members I3, l3 are flared slightly outwardly from each other,'and the foreward end portions l1, H of the bottom members i4, i4 are flared slightly downwardly. A used blade-recelving chamber 18 is formed by the top memher is, having a longitudinal recess 20, the side member 2|, 2i and the end member 22, the recess 20, however, not being an essential element of the device. I

Fixedly attached to the inner face of each side wall I2, and at the lower part thereof, is an elongated angular member having the sides 23 and 24, the latter of which are spaced from each other and form a blade magazine compartment 25 with the sides l2, l2 and the top i0.

While I have shown the guide members ll, H as spaced from each other, they may be a single piece, if desired.

The construction of the blade magazine porsaid longitudinal movements, and further, to altion of the above described blade magazine holder spring 33, the studs 30, 30 passing through the openings 34, 34 of the spring 33.

It will thus be seen that means may be employed whereby the outermost blade I may be withdrawn forwardly from the magazine and the magazine holder, while the studs 30, 30 will retain the remainder of the stacked blades I00, I00 within the magazine, and that, upon such withdrawal, the spring 33 will abut the then outermost blade I00 for a repetition of the withdrawal.

performance.

The operating mechanism for the withdrawal of a blade from the blade magazine and the magazine holder is not an element of the devices set forth in this application, but is an element of a razor head with which the described devices are adapted to operate.

The mechanism covered by a razor head adapted to remove a previously deposited blade, deposit a new blade, or both, is of various constructions, and, as it is not a part of this invention, it is described only in a general way in order to-indicate the operations of the elements of the combined blade magazines and magazine holders of my invention.

The devices of my invention are adapted to cooperate with razors in which the mechanism adapted for the purposes described operates upon a longitudinal movement of the razor head and of my devices with respect to each other. In order to accomplish this, the razor head carries at least one extended stud capable of being inserted within an opening in the outermost blade carried by the blade magazine, the construction being such that th stud is withdrawn'from its extended position during one directional longitudlnal movement of the device, thus allowing the free passage ofthe blade magazine to deposit the outermost blade above the said stud, and that, when so deposited, the stud will be extended into the opening of said blade. It is evident, therefore, that upon a reverse longitudinal movement, during which my device is withdrawn from contact with the razor, the outermost blade will be retained on the razor head, while the remainder of th blades in the magazine will be retained therein for a repetition of such blade withdrawal performance.

The mechanism may also be so constructed, if desired, that the withdrawal of the blade magazine will carry with it a previously deposited blade.

It is evident that, as a blade must be in a precise position upon the razor head in order that an opening in the blade will allow of the introduction of a razor head stud, guiding means must be supplied to insure an exact longitudinal movement of the razor head element and the magazine during the co-operation of these two devices and such means are a particular feature of my devices of this application The co-operating guiding elements of my described devices and a guard element of a razor head are shown in Figure 5, in which a vertical cross-section of a guard element of a razor head is shown in dot-and-dash lines.

The illustrated guard element is a part of a generally known safety razor and comprises the slightly convex body member 40, having a plurality of downwardly extended teeth 4|, 4| upon each side thereof, and a handle 42.

It will be noted that when the razor guard and my devices are in position for longitudinal movements with respect to each other, the guide elements 24, 24 abut upon opposite sides of the top 40 of the guard, and the guide members I3, I3 of my device abut upon the teeth 4|, 4| upon opposite sides of the guard, thus preventing any side movements between the guard and my device.

It will also be noted that the bottom members I4, I4 of my device are parallel with the lower faces of the teeth I4, I4 of the guard. and are separated therefrom by a distance just sumcient to allow the two elements to move easily with respect to each other, and hence, a vertical movement between the guard and my device is practicaliy impossible.

It will thus be seen that the guide elements of my devices will maintain it in a longitudinal position upon the guard of a razor during their longitudinal movement with respect to each other.

AS in some razors the guard member consists of a bar spaced from the body of the razor instead of a plurality of teeth, as described, by the "words guards or "guard elements, I mean both such bar guards and such teeth guards.

While I have described the application of my devices to the form of razor illustrated, I wish to be understood that I do not limit the application of my devices to that particular form of razor, which is shown and described simply for the purpose of explaining the operation of my devices with safety razors,

It will thus be seen that my invention presents devices comprised of a blade magazine adapted to contain a plurality of stacked blades from which one blade may be withdrawn while the remainder are retained within the magazine, said.

magazine being a unitary part of a blade magazine holder adapted to co-operate with a razor head element to allow and insure a longitudinal movement of my devices and the razor head element, and to position a blade within saidmagazine upon a razor head element, and allow blade withdrawaI mechanism of the razor head element to withdraw a single blade from said magazine.

I do not limit myself to the size, shape, number, arrangement or material of parts as shown and described, as these are given simply for the purpose of clearly describing my invention.
