Patented Mar. i938 Claims.

This inventionrelates to an improved magazine razor ofthe type that positively feeds vblades endwise from a stack of blades in a. magazinel to a shaving head which can be either separable from r,th'es magazine or permanently attached thereto. v

I'he invention resides in a structure that in sures the feeding of )iut one blade ata time andv `thus prevents jamming which jamming is caused outlet slot ybefore the preceding blade has been fully ejected.' The insurance against jamming is due to the use of'a depressor which-is engaged by an electing slide which depressor holds the stack of bladesdown during and until the end 0f the electing stroke and then releases the stack only when the slide is in position to initiate the projection of the next blade.- e

'Ihe invention is illustrated in the accompanying drawing. Figure l 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blade depressing device incorporated therein; Figure 2 is a longitudinal section showing the ejecting slide partly withdrawn.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 thev magazine. Figure 4 is' a side View of the razor( showing the shaving headin position for receiving a blade. Figure 5, is a section 'taken on line 5 5 in Figure. 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 butwlth the depressor i'n section to show its engagement with the slide. A

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 inthe drawing as forming the handle of the razor. The magazine is designed to preventjamniing by de pressing'the 4stack of blades asvsoon as the top f' one is started on its passage from the ,magazine and holding thestack depressed until the blade in transit is iinally ejected. The depressor holds being engaged slide. i

The depressor retreated -entirely from. the stack by the ejec r slide only after theejector slide has fully completed the ejection Vof a blade and is returned to its rearmostA or pick-up position. i y The magazine comprises a easing I0, usually re in shape and containing a stack of blades. )stack is usually placed in the magazine from 2.111339; MAGAZINE FonMAGAzINE RAzoRs (lctavi'us Victor Rodrigues, Passaic, N.

' by feeding a second thin4 blade into 'a narrow the stacklow enough' to prevent the top bladev by the front end of the ejector (c1. ,zoe-16) the rear `and I show the commercial type vof holder I2 vslidable by a grip I3 and provided with a spring I4 which spring bears von the bottom of the stack to constantlyA press the stack upwardly toward the top plate I5 ofthe casing. Inside the casingI show a lining I6 includingfa top plate I I which is provided with a slot. I8. The slot has a broader top in the form of a groove I9' which construction provides a track 2li for the depressor. The depressor 2l is slidable inthe groove IB and has the anged part of which the flanges 22 slide in the groove I9. The depressor has bevelled edges,23 on the anges 22 and in the path of these bevelled edges are'projections 2d in the top plate Il at diagonally related corners of the groove part li 9oi` the slot I8. The depressor slides in the groove with a slight lateral play but is held in its path by friction on the @plates Il and I5. l

If desiredl this friction can be increased by spring iingers 25 formed by saw-cuts in the AiiangesA 22. It will be evident, that when the de- '.pressor reaches one end of the groove i9 it is shifted laterally to one side and when moved to the other end the depressor is moved .laterally to thev other side. One position is shown in liligurev .5 and the other position shown in Figure 7.

The ejector slide 26 for blades is at and slides -between the plate II and the stack holder I2 vand is provided with a grip 2l for its manipulation. The front Iend 2 2 of the slide engages and pro-- pels a blade from the stack. The slide is slotted from the front end rearwardly as at 29 and has an ofi-set portion 30 in the slot at its rear end. The slot29 is Wide enough .to receive the depressor 2| with a comfortable fit and the od`set part 20 is slightly wider and longer than the de` pressor -2I to receive it. 'Ihe magazine casing y is provided with a slit 2l for the escape of a blade propelled by the ejector slide. The magazine is long enough to provide a space 32 sumcient to allow the depressor to be carried beyond the stack to the rear in order to let 'the stack rise under the inuence of the spring Il to allow theftop blade of the stack to rise to the planev oi the slide 2t.

In operating the device we assume the depressor is in thespace 32 and the slide is in ndrmal position asin 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 yclears the stackffthe stack rises and rests against 4 the top plate I1. The slide 28. is now pushed forwardly and end 28 engages'the top blade and propels it through the slit 3I. 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 olf-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 oi-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 oif-set part to be retreated with the slide. 'I'his is the normal position of the depressor. v

When another blade is desired the slide 26 is pulledrgback by means of the grip 21 and the shoulder 34 of the oil-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 olf-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.
