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.
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
If desired this friction can be increased by spring fingers
The ejector slide
In operating the device we assume the depressor is in the space
When the slide fully ejects a blade the depressor engages the cam or off-set edge
When another blade is desired 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.
1. A magazine for magazine razors comprising a casing, the casing having a chamber for storing a stack of blades, a slide for ejecting a blade at a time from the stack, the slide having a slot arranged longitudinally therein, a depressor slidable in the casing and located in the slot, said depressor being slidable along the top of the stack and beyond the stack at the rear thereof, and co-operating means on the depressor and the slide for moving the depressor rearwardly beyond the stack by engaging the slide, said means being disposed to initiate said engagement at the expelling position of the slide only.
2. A magazine for magazine razors comprising fa casing having a chamber for a stack of blades, a spring under the stack, an ejector slide for ejecting the blades successively from the top of the stack, a depressor for holding the stack down, the depressor being slidable beyond the rear of the stack, and co-acting means for moving the depressor by means of slide, and projections at the ends of the path of the depressor for shifting the depressor into co-operative contact with the slide only at the end of its path of travel.
3. A magazine for magazine razors comprising a casing having a chamber for a stack of blades, the magazine having an outlet slit for the endwise passage of a blade from the stack, a spring for holding the stack in raised position, a depressor slidable over the stack of blades and to the rear thereof, a slide for ejecting a blade from the stack and having an edge to engage the depressor to move it forward over the stack, the depressor and slide having co-acting means for engaging the depressor to return the depressor to its position in rear of the stack, and automatic means for releasing said depressor from the slide at the completion of the return movement of the slide.
4. A magazine for magazine razors comprising a casing having a chamber for a stack of blades, a spring under the stack, a guide plate over the stack and having a slot therein with off-set portions at diagonal corners, a depressor slidable in the slot and with a limited side movement therein whereby the depressor is shifted laterally by engagement with the said off-set portions, a slide for ejecting blades and having a slot with a laterally off-set portion at the rear end of the slot, said off-set portion receiving the depressor when the depressor is moved laterally at the end of its forward stroke.
5. A magazine for magazine razors comprising a casing for a stack of blades, a spring holding the stack in position for feeding, a slide movable across the top of the stack for ejecting blades successively from the stack, a fixed guide blade above the slide, the guide plate having a slot with off-set portions at two diagonal corners, the slide blade having a slot under the slot in the guide plate, a depressor for engaging the top of the stack and slidable in the slots, the depressor having guiding edges for moving it laterally at the ends of its sliding movement, the slide having a side off-set portion in the slot and at the rear end of the slot, the chamber having space for the depressor to clear the stack at the rear thereof.
