This invention relates to an improved device for feeding blades from a stack of blades and is particularly adapted for use in razors known in the trade as magazine razors.

The object of the invention is to insure the feeding of only one blade at a time to insure against jamming more than one blade in the a restricted passage through which they are advanced one at a time from the stack.

Another object of the invention is to prevent the feeding of the top blade by frictional engagement with the feeding slide or tongue.

A still further object is to cause the withdrawal of a blade partly fed if such feeding is inadvertently done while the shaving head is not in position to receive the blade.

The device for feeding keeps control of the blade until the blade is entirely ejected and at that time the slide automatically re- 22 leases the blade. This is of particular advantage in those razors that include a tilting shaving head and the head is free to be tilted in view of the release of the blade, which it contains, from the feeding means.

The invention is illustrated in the accompanying drawings in which Figure l is a central longitudinal section of a magazine razor with the shaving head in position to, receive a blade and showing a blade in position in the shaving head, the shaving head being shownpartly in elevation. Figure 2 is an enlarged section on line 22 in Figure 1 but showing the stack of blades in elevation. Figure 3 is an end view of the razor shown in Figure 1. Figure-4 is an enlarged sectional vlew of the shaving head and part of the blade magazine, this section being taken on the plane of the top surface of the blade.

Figure 5 is a detail section of the front part of the stack and the ejecting slide and the rear end of the stack of blades.

'- Figure 6 is an end view of the blade magazine with the post that supports the shaving head in section. Figure 7 is a detail section and slide in feeding position and Figure '13 is a similar view with the slide in releasing position. F lgure 14 1s a perspective view of the end of the slide shown in Figure 10.

The invention is illustrated as embodied in a razor of a known commercial type and comprises a handle 10 which is square in cross section and is hollow. The top of the handle is provided with aishaving head 11 pivoted at 12 on a post 13 whichis on a foot 14 inserted in the end of the handle and forming a closure except for the restricted passage or slit 15 for the passage of a blade. A pin 16 can be used to hold the foot 14 in place. The shaving head includes a blade platform 17 and a guard 18 and also a gripping means for the blade such as the strip 19 of spring metal. The blade in the head 1's shown at 20.

Inside thehandle which forms a magazine is placed the stack of blades 21 usually supplied, for convenience, in a. clip 22. The clip has end walls 23 and 24, the rear wall 24 usually having a rearwardly extending lip 25. The clip has a slot in the bottom through which a spring 26 extends to push the stack of blades upwardly for feeding. The spring is insertable and removable by the bolt 27 to which it is secured. The clip rests on a track 28 formed by the inwardly bent sides of the sleeve 29 held in the handle by the projection '30. The blades are fed by a slide 31 which fits into the handle and is U-shaped and has.

a grip 32 at its end-by means of which it is slid back and forth. The slide 31 passes with a sliding fit between the bolt 27 and the top 45 of part of a blade and the ejecting slide in wall of the handle which is above it and also 'passes over the stack of blades and is used for projecting a blade at a time from the top of the stack. The parts as described up to the point are old and well-known and are subject to equivalent constructions and devices.

The invention resides in means for retaining control of a blade both in advancing it or pullin it back until the blade arrives at a point w ere it is to be released and at that point the release is made. The release is preferably automatic and is usually made after the blade is wholly outside the casing or holder. The slide that controls the blade and the blade itselfhave co-operating means for connecting them and in the form shown it is the blade that is recessed and the slide that has a tongue held in alignment with the 7 blade and thus interlocked until the tongue is 'moved laterally relative to the plane of the blade at the point where the release takes place. The spring "action resident in the tongue can be utilized to cause this lateral release.

The blade is propelled by the front ed e of the slide 31 as by the end 31. The sli e is provided with a tongue 33 which has a spring action to move it so that the enlarged end 34 of the tongue is out of the plane of the slide. This will be noted from Figures 1,3,8 and 9.

The blade 20- is provided with a recess 35- blade by the inside face of the handle ll).

When the slide is pushed forward toward the shaving head the blade is pushed ahead of the slide. The tongue engages only the.

top blade as it is no thicker than a blade and has a tendency to spring away from the stack and has an additional safeguard in a slightly rounded lower edge 36. If, during this forward feeding of the blade there is any reason for pulling the blade back, as in case the shaving head is not aligned with the handle the blade can be pulled back as'the enlarged end '34 of tongue 33 is in the recess 35. It will thus be seen that the slide and each blade having co-operating means for preventing longitudinal separation of any blade and the slide until the blade is full shaving head, that' is, until t e blade is completelyejected, The release of the blade is automatic as the clearance under the spring plate 19 of the shaving head and any necessary clearance'in the enlarged part 37 of the restrlcted pasage 38 of the handle allows seated in the.

the tongue 33 to'snap out of the plane of the blade 20 and thus out of the recess35. When the slide is pulled back to pick up the next blade it is -free of the blade 20 and when it reaches the inner end of the assage 38 it is in the plane of the to wall o the slide 31.

The edge or zhoul er 31'. of the slide is in advance of the shoulder39 on the other side of the tongue. This causes the blade to be pushed on its outer edge and the tendency is to push the blade with a slightbackward in-. clination along the uiding edge 40 of the head. This seats thefiilade paralled with the giiggli when the feeding of the blade is com- P e Various forms of recesses and ton ues forv connecting the. slide and blade can used and other means of release can beemployed to separate the blade and slide when the blade has been delivered into the shaving head. y The head 11 can be tilted readily as the head is cutaway at 41 to allow it to pass the pujecting-ton ue 34. The blades are of the wa er type an the recesses and tongues employed are small with the result that the tongue that normally projects from the handle is'hardly noticeable.

' In Figures 10 to 14 a modification is shown. In this form the spring tongue 33 has a tendency to bend toward the stack, or inwardly. This necessitates'the placing of the clearance or cut-away portion of the passage 38 on the inner face shown at 39 in Figure 11. In this construction the tongue is held in the plane of the slide which in turn is held in place by the spring 26. When the tongue in either of the above constructions is pulled all the way back, as in Figures 4, 5 and 10 the spring 26 forces the stack with suflicient energy to insure the seating of the tongue 34 of the slide in the recess 35 of the top blade.

In case the slide is made of material with no spring to it the tongue can be'made as in Figure 14. In this form the tongue projects from a small plate 42 and this in turn is welded or otherwise secured in a cut-away part of the slide 31 Various changes can be made in the form and proportions of parts ofthe device without departing from the scope of the invention.
