This invention relates to a razor of the magazine type which houses a stack of blades in a magazine and is provided with an ejector which successively feeds a blade at a time from the stack into a shaving head which head is usually pivoted on the end of the razor. The head is swung to a position with its blade channel in line with the blade-feeding passage of the magazine when a fresh blade is to be placed in the head.
The object of the invention is to provide a blade feeding device which is not subject to jamming either by two blades being advanced or partially advanced at the same time into the blade slot or a blade and the thin ejector being jammed in the blade slot. This prevention is due to a construction which guards against the feeding of the top blade of the stack unless the ejector is fully returned and also guards against such full return while a blade is in transit to the shaving head.
Another object of the invention is the provision of a stack holder which is limited in its return or outward movement in the blade magazine which provides a wide accessible opening for the insertion of the stack of blades which are usually in a clip, and which provides a spring depressing or compressing element by which the spring which keeps the stack of blades pressed against the ejector is made inactive while the stack holder is drawn back.
Another object of the invention is to provide a latch by means of which the initiation of movement in the ejector secures the stack holder against movement and vice versa and in this way there is an insurance against the simultaneous withdrawal or movement of both the stack holder and the ejector.
The invention also has for an object the provision of certain details of construction which details will be hereinafter more fully described and embodied in some of the claims.
The invention is illustrated in the accompanying drawing in which
The preferred form of razor consists of a handle in which the magazine of blades is placed and a shaving head pivoted on the end of a post projecting from the handle. The handle is composed, in the form illustrated, of a trough-like member
The stack of blades, either alone or in a clip, is placed in a stack-holder
The inner member has a slot
The spring is held by the pin
The frame
It will be evident that when the ejector is pulled back to pick up a blade the spring
To prevent the ejector and the stack holder from being pulled out at the same time I provide a latch which prevents each from moving when the other is moved from its inner position.
The form shown is a latch
The various parts can be varied as to shape and modified in proportion without departing from the scope of the invention as set forth in the claims.
I claim:
1. A razor, a magazine for holding a stack of blades, a shaving head, an ejector for moving the top blade endwise into the shaving head, and means actuated by a blade in transit for preventing the complete return of the ejector.
2. A razor comprising a magazine for holding a stack of blades, an ejector and means actuated by a blade in advance of the stack for preventing the complete return of the ejector.
3. A razor comprising a magazine for holding a stack of blades, an ejector for a single blade from the stack and means for preventing the movement of a blade from the stack while the ejector is advanced in front of its pick-up position.
4. A razor comprising a magazine for holding a stack of blades an ejector for advancing a blade from the stack, a pivoted lever having one end to engage the stack and the other end to engage the ejector to limit the rearward movement of the ejector when a blade is in transit.
5. A razor comprising a device for ejecting a blade from a stack of blades and means operated by a blade in the state of ejection for preventing the full return of the ejector.
6. A razor comprising a magazine for a stack of blades, a pivoted lever in the magazine, an ejector having means for limiting its rearward movement, and means on one end of the lever for forming an additional limiting means for a shorter stroke of the ejector when the other end of the lever is engaged by a blade moved from the stack.
7. A razor comprising a magazine for a stack of blades said magazine including a casing, one wall of which guides an ejector, an ejector for advancing a blade from the stack, a pivoted lever with one end to engage the stack and the other end to engage the ejector, and a spring in said wall to resiliently hold the lever in normal position.
8. A razor comprising a magazine for a stack of blades said magazine including a casing, one wall of which guides an ejector, an ejector for advancing a blade from the stack, a pivoted lever with one end to engage the stack and the other end to engage the ejector, and a spring in said wall to resiliently hold the lever in normal position, the casing wall having a notch to receive the end of the spring whereby said wall is locked against longitudinal movement.
9. A razor comprising a magazine for holding a stack of blades, an ejector for pushing a blade from the stack, and a means for holding the top blade against movement by friction with the face of the ejector.
10. A razor comprising a casing, a stack holder slidable in the casing and adapted to receive a stack of blades, a spring for normally bearing under a stack and means for making the spring inoperative when the stack holder is retreated.
11. A razor comprising a casing, a stack holder slidable in the casing and adapted to receive a stack of blades, a spring or normally bearing under a stack, the holder and spring having a connection whereby the spring is flattened when the holder is partially withdrawn.
12. A razor comprising a casing, a stack holder slidable in the casing and adapted to receive a stack of blades, a spring for normally bearing under a stack and a connection between the holder and the spring for utilizing the spring as a means for limiting the outward movement of the holder and for utilizing the holder for making the spring inoperative under the stack.
13. In a razor, a casing, a jointed stack holder slidable in the casing, and means for limiting the movement of the holder whereby the free end of the holder uncovers the inner end for the endwise insertion of a stack of blades.
14. In a razor, a casing, a jointed stack holder slidable in the casing, and a spring in the casing, the spring having a limited sliding connection with the holder whereby the spring is made inoperative and acts as a stop for the holder in its outward movement.
15. In a safety razor, a slidable stacky holder comprising two members hinged together, one member forming a grip and the other member receiving a stack of blades when the grip member is swung on the hinge.
16. In a safety razor, a casing, a slidable stack holder in the casing, a leaf spring secured at one end to the casing and having a longitudinal slot, a bar on the holder and over the spring and a pin on the bar and riding in the slot.
17. In a safety razor, a casing, a slidable stack holder in the casing, a leaf spring secured at one end to the casing and having a longitudinal slot, a bar on the holder and over the spring and a pin on the bar and riding in the slot, the holder consisting of two hinged members one of which swings down to give access to the other member when the holder is partly withdrawn.
18. In a razor, a casing, a slidable stack holder in the casing, a slidable blade ejector in the case, and a latch disposed in a manner that causes either of the sliding elements, when moved, to hold the other element against movement.
19. In a razor, a casing, a slidable holder in the casing, a slidable blade ejector in the casing, and a transversely movable latch engaged by an operated slidable member to hold the other against movement.
20. In a razor, a casing, a slidable holder in the casing, a slidable blade ejector in the casing, and a transversely movable latch, the holder and ejector each having a rounded notch engaging the latch, the latch having rounded ends to engage the notches alternately in order to clear one notch when seated in the other.
In testimony whereof I affix my signature.
