Description

atented OFFICE OB COMPANY, OF NEW YORK, N. Y., A CORPORATION SAFETY RAZOR Application led September 7, 1929. Serial No. 390,88?.

This invention relates to a razor of the magazine type which houses a stack of blades in a magazine and is rovided with an ejector which successively eeds 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 s ring which keeps the stack of blades presse against the ejector is igiaxllie inactive while the stack holder is drawn 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.

view ofthe razor with its parts separated.

Figure 3 is a perspective view of a form of clip for holding a stack of blades.

The preferred form of razor consists of a handle in which the magazine of blades is4 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 10 which forms three sides of a casing, the fourth side or top being supplied by a frame 11 which supports the anti-jam mechanism. These parts are held together by a sleeveV 12 which is forced over the outside with a very snug lit in order to prevent separation of the parts but loose enough to be taken oif by tools in case the razor is to be taken apart. The ejector 13.

has a top blade which has a projection 14. which picks up the end of a blade and forces it forward and side wallsl which fit inside the side walls of the member 10 and rest on the ribs 16 on each side of the member. The finger-piece 17 is used for manipulating the ejector which has a slot 18 wider than the blades in the stack which slot has itsfront end 19 positioned to act as a stop when 1t engages a stud 20 on the under face at the rear of the frame 11. This normal stop allows the ejector to move back far enough to allow the front end 14 tojenga e the rear edge of the top blade. The bla es 21 are arranged 1n a stack and are fed forward in succession by the ejector. A spring 22 presses on the under side of the stack to keep the blades together and to hold the stack up against the ejector 13. In commercial practice the stack is placed in a clip such as shown at 23, this for easy handling. The clip has a slot 24 in the bottom for the spring to pass through to engage the under side of the stack.

The st ck of blades, either alone or in a clip, is p aced in a stack-holder 25 which slides in the casing under the ribs 16, and has an upwardly projecting part 26 which slides between the ribs 16. I refer to make this holder of two members hinged together at 27. The inner member always remains in the casing but the outer member drops down and hangs suspended on the hinge 27 when the holder is partl withdrawn. The

inner member has an en wall 28 which co nsA liront end Il@ also serves to holf.
