2,111,739 MAGAZINE FOR MAGAZINE RAZORS Octavius Victor Rodrigues, Passaic, N.J., assignor to Magazine Repeating Razor Company, New York, N.Y. Application filed Feb 12, 1936. Serial No. 63,507 5 Claims. (Cl. 206—16)

This invention relates to an improved magazine razor of the type that positively feeds blades endwise from a stack of blades in a magazine to a shaving head which can be either separable from the magazine or permanently attached thereto.

The invention resides in a structure that insures the feeding of just one blade at a time and thus prevents jamming which jamming is caused by feeding a second thin blade into a narrow outlet slot before the preceding blade has been fully ejected. The insurance against jamming is due to the use of a depressor which is engaged by an ejecting slide which depressor holds the stack of blades down during and until the end of the ejecting stroke and then releases the stack only when the slide is in position to initiate the projection of the next blade.

The invention is illustrated in the accompanying drawing. Figure 1 is a cross section of a blade magazine of a conventional type having my improved blade depressing device incorporated therein; Figure 2 is a longitudinal section showing the ejecting slide partly withdrawn. Figure 3 is a perspective view of a depressor used in the magazine. Figure 4 is a side view of the razor showing the shaving head in position for receiving a blade. Figure 5 is a section taken on line 5—5 in Figure 3. Figures 6, 7 and 8 are similar views showing the ejector slide in various positions and its action on the depressor. Figure 9 is a section similar to Figure 8 but with the depressor in section to show its engagement with the slide.

The invention is applicable to razors that feed blades endwise into a shaving head, the blades being stored until used in a stack placed in a magazine. The magazine is shown in the drawing as forming the handle of the razor. The magazine is designed to prevent jamming by depressing the stack of blades as soon as the top one is started on its passage from the magazine and holding the stack depressed until the blade in transit is finally ejected. The depressor holds the stack low enough to prevent the top blade being engaged by the front end of the ejector slide.

The depressor is retreated entirely from the stack by the ejector slide only after the ejector slide has fully completed the ejection of a blade and is returned to its rearmost or pick-up position.

The magazine comprises a casing 10, usually square in shape and containing a stack of blades. The stack is usually placed in the magazine from the rear and I show the commercial type of holder 12 slidable by a grip 13 and provided with a spring 14 which spring bears on the bottom of the stack to constantly press the stack upwardly toward the top plate 15 of the casing. Inside the casing I show a lining 16 including a top plate 17 which is provided with a slot 18. The slot has a broader top in the form of a groove 19 which construction provides a track 20 for the depressor. The depressor 21 is slidable in the groove 18 and has the flanged part of which the flanges 22 slide in the groove 19. The depressor has bevelled edges 23 on the flanges 22 and in the path of these bevelled edges are projections 24 in the top plate 17 at diagonally related corners of the groove part 19 of the slot 18. The depressor slides in the groove with a slight lateral play but is held in its path by friction on the plates 17 and 15.

If desired this friction can be increased by spring fingers 25 formed by saw-cuts in the flanges 22. It will be evident, that when the depressor reaches one end of the groove 19 it is shifted laterally to one side and when moved to the other end the depressor is moved laterally to the other side. One position is shown in Figure 5 and the other position shown in Figure 7.

The ejector slide 26 for blades is flat and slides between the plate 17 and the stack holder 12 and is provided with a grip 27 for its manipulation. The front end 28 of the slide engages and propels a blade from the stack. The slide is slotted from the front end rearwardly as at 29 and has an off-set portion 30 in the slot at its rear end. The slot 29 is Wide enough to receive the depressor 21 with a comfortable fit and the off-set part 30 is slightly wider and longer than the depressor 21 to receive it. The magazine casing is provided with a slit 31 for the escape of a blade propelled by the ejector slide. The magazine is long enough to provide a space 32 sufficient to allow the depressor to be carried beyond the stack to the rear in order to let the stack rise under the influence of the spring 14 to allow the top blade of the stack to rise to the plane of the slide 26.

In operating the device we assume the depressor is in the space 32 and the slide is in normal position as in Figure 4. The stack is pressed by the spring against the slide 26. The slide is drawn all the way back and its front end 28 clears the stack, and the stack rises and rests against the top plate 17. The slide 26 is now pushed forwardly and end 28 engages the top blade and propels it through the slit 31. As the slide and the blade proceed the end 33 of the slot 29 engages the depressor which is in the position shown in Figure 7, that is, not in the off-set part 30. When the end 33 of the slot reaches the depressor it pushes the depressor forward and still free of the off-set part 30, as shown in Figures 2 and 9 and the bottom of the depressor rests now on the stack in the same plane as the bottom face of the slide. Any rearward movement of the slide 26 after a partial forward movement leaves the depressor on the stack as the slot 29 does not frictionally engage the depressor which is clear of the off-set 30. This allows the depressor to remain in depressing position and the slide can not pick up another blade. In fact a blade can not be picked up until the depressor returns to the chamber or space 32.

When the slide fully ejects a blade the depressor engages the cam or off-set edge 24 shown at a in Figure 8 and is moved laterally as shown in Figure 5. This moves the depressor over into the off-set part 30 and the depressor is engaged by the front edge 34 of the off-set part to be retreated with the slide. This is the normal position of the depressor.

When another blade is desired the slide 26 is pulled back by means of the grip 27 and the shoulder 34 of the off-set part 30 engages the depressor and pulls it back until the depressor is in the recess 32. At this point the depressor engages the cam edge 24 at b, is moved laterally and released from the edge 34 of the off-set part 30. The slide continues to travel back until it picks up a fresh blade and the operation described above is repeated. This device insures against two blades being jammed in the magazine as the ejecting stroke of the slide causes the depressor to be pushed over the stack to hold the stack down and it does not retreat until it is engaged by the shoulder of the off-set part of the slide at the completion of the stroke to be carried back to clear the stack at the next operation of the slide.

Various changes can be made in the form and proportion of the parts without departing from the invention as set forth in the claims.
