Y ABSIGNOB, BY IESNE ASSIGNMENTS, '10 GILLETTE SAFETY RAZOR COMPANY, 01' BOSTON, MASSACHUSETTS, A CORPORATION OF DELAWARE man won Application filed January 15, 1927. Ierial 110. 101,80.

My invention relates to improvements in the class of safety razors in which several separate blades are maintained in position to be successively inserted in a blade hold- '5 er respecting its guard, with the cutting ed e of the blade in position for shaving.

n object of my invention is to provide means for successively feeding blades, as required forv use into the blade holder adjacent to a guard with means for automatically positioning the blade in the holder with its cutting edge in shaving relation to the guard. v

.Another object is to detachably retain a. 16 magazine containing several blades in position upon the handle of the razor so that when it is desired to remove a blade from the holder and replace it with another blade for use the magazine may be applied to the 0 handle adjacent to the blade holder, and when a new blade has been inserted in the holder from the magazine the latter may be removed for convenience in use of the razor.

My invention comprises novel details of 2 improvement that Wlll be more fully hereinafter set forth and then pointed out 1n the claims.

Reference is to be had to the accompanying drawings forming a part hereof, wherein a Fig. 1 is a perspective view illustrating the parts of my improved razor in position for removing one of the blades from the blade holder and inserting another blade therein;

Similar numerals of reference indicate corresponding parts in the several views.

In the accompanying drawings a blade holder is indicated at 1 ada ted .to detachably retain a blade 2. The lade holder is shown provided with a relatively flat seat at 1a upon which the blade rests for use and along which the blade may be slid to and from shaving position, the holder being shown provided with a spring-acting retaining member 3 having its free edge spaced or positioned at a suitable distance from the seat 1a to bear against the blade. to detachably retain it upon the seat. The rear edge or the heel 2a of the blade abuts against a longitudinal stop or wall 4 on the holder when in shaving position, a space at 5 being provided between the seat and the retaining member 3, whereby the latter is suitably positioned relatively to the blade. 85 A handle 6 is attached to the blade holder 1 in any desired way. In the form shown in Figs. 1 to 5 the handle is pivotally attached to the blade holder by a pivot at 7 and the holder is pro ided with a longitudinal recess 16 in which the handle fits so that the blade holder may be turned parallel to the handle for receiving blades (Figs. 1 and 4), or may be set substantially at a right angle to the handle for shaving, (Figs. 2 and 3). In the form shown in Figs. 9 to 11 the handle is secured to the blade holder 1 in a direction substantially at right angles thereto for shaving purposes. At 8is a magazine adapted to contain a plurality or stack of blades 2. The magazine is shown in box-like form having an inner chamber or space 8a for the blades that lie flatwise, the magazine having a cover at 9 which is removable to admit the blades into the magazine. I have shown the side walls of the magazine as provided with rooves 8b in which the cover slides, (Figs. and 13). Between the cover and the blades is a spring 10 normally bearing against the blades to keep them in stacked relation. The spring illustrated is shown rovided with a fiat back portion 10a bearmg against the cover and end portions 10?; bent reversely to bear upon the blades to keep them snugged in a stack. By pulling out the cover 9 the blades and spring may be placed in the magazine and the cover may be'slid back to retain the blades. At one end the magazine has an opening or slot at to permit ejection of the endmost blade, the latter slidably resting against the outer wall 8d of the magazine. A blade I ejector or plunger is indicatedat 11 which is slidable along the wall 8d and is shown ided-in lateral grooves 11' in the side walls of the ma azine, (Figs. 7 and 13).. The inner end 0 the ejector is maintained in line with the endmost blade of the stack, opposite the spring 10, and in register with the outer opening 80, whereby when the ejector is pushed inwardly a blade will be e'ected from the magazine, (Figs. 1, 6 and 8 The ejector 11 is shown provided with a stop 1111, which may be punched out of the metal of the ejector, slidable in slot 80 in wall 8d and adapted toengage end portions of the wall 8d to limit the motion of the ejector and prevent it from being pulled from the magazine and from pushing a blade too far into the blade holder 1.' A finger piece 11b on the ejector permits ready mani ulation of the latter.

n the form shown inFi'gs-l to 7 the magazine is adapted to be detachably supportedupon the razor handle 6 so'as to be located in juxtaposition to an end of the blade'holder 1 for insertion of'blades from the magazine into said holder. I have shown the meansfoi' detachably supporting the magazine upon the handle 6 comprising longitudinal grooves 6a in the handle slidably receiving inwardly extending spaced rojections'or ribs 8 on the spaced proecting walls 8" of the magazine that re- 4 of holder 1'.

tween the stops 13.

ceive the handle therebetween, and a screw 12 carried by one of said walls adapted to slid adjacent to the blade holder with the delivery opening or slot in juxtaposition to and in alignment with the end of the blade holder and with the endmost blade of the stack in such position as to slide into the holder along the seat 1a, and the magazine will be fastened to the handle b the screw 12, (Fig. 1). The ejector 11 will be drawn outwardly so that the endmost blade will be pushed by the spring 10 into position in front of the ejector and with respect to the seat 1a of the blade holder and the ejector then will be pushed inwardly, thereby sliding said blade into the blade holder between the seat 1a and the retaining member 3. As said blade slides into the blade holder it will engage a blade in the holder and push it therefrom, (Fig. 8), and at the termination of the inward stroke of the ejector the blade it is pushing will be located in the holder 1. The'blade engaging or delivery end of the ejector 11 is preferabl located atan angle to the plane of the si es of the ejector, as indicated at in Fig. 8, so'as toengage a portion of the blade at one side of its median line, thereb tending to cause the heel'of the blade to e pushed against the stop 4 of the holder 1 to guide the cutting edge of the blade in proper position for shaving. I have shown the edge 3a of retaining member 3 as angularly disposed respecting the shaving edge of the blade in the holder to aid the location of the blade in the holder as it is slid endwise thereinto, (Fig. 8).

I provide means to positively adjust the blade within the holder so that the cutting edge of the blade will be in proper shaving position. For such purpose movable stops or lugs 13' are adaptedto engage the corners of the cutting edge of the bladeand means are provided to cause said stops to tend to push the heel of the blade against the stop 13 as carried by a member 14 that is piv- I have illustrated the stops otally supported on the holder at 15 as by means of ears 16 on the latter, the member l l'having a portion at 14a in the form of a guard for the cutting edge of the blade be- VVhen the stops 13 engage the blade edge and snug the blade in proper position in the holder 1 the guard will be in proper shaving position respecting the blade edge. In the form shown in Figs. 1 to I provide means for automatically operating the guard and stops 13 when the holder 1 is turned from one position to edge. The spring 18 is shown in the form r of a bow-spring located in a recess 1' in the adjacent side of the holder and bearing against the member 14, (Figs. 3 and 5).

When holder 1 is turned to a position arallel with the handle to receive a bla e the spring 18 will ush the'member 14 and the stops 13 away rom blade-engaging position to permit insertion of a blade into the holder, (Figs. 1, 4 and 5), at which time the pro jections 14' on member 14 will engage the blade holder such as at the ears 16 to retain member 14 with the stops 13 away from the blade, as indicated in Fig. 5. When the blade holder has received the blade and is turned to shaving position respecting handle 6 the travel of the projection 14?) against the handle will cause tilting of member 14 toward the blade, whereby the stops 13 will engage the blade edge and member 14 and the guard will be retained in shaving'position, (Figs. 2 and 3).

In the form shown in Figs. 9 to 14 the blade magazine 8 and. the blade holder areassembled in cooperative relation for insertion of blades in the blade holder other'than by mounting the magazine upon the handle 6. In such form the ma azine 8 is provided, at one sideof the c amber or s ace 8a, with a spring-acting retainer 19 a ong one side of base 8;, shown having a curved portion 19a at its free ed e to on age a groove 1" in the back of lade ho der 1,

and with a retainer member 20 spaced on the other side of the base to enga e projection 14b of member 14 of the bla e holder, the operative edge 20a. of said member being shown curvedto receive a correspondingly curved portion 14" of rojection 146 as illustrated in Fig. 12. When a blade is to be applied in the blade holder the latter is inserted, in an inverted position, between the retainer 19 and the member20, and the engagement of said member with the projection 146 will cause the member'14 to tilt on its pivots 15 to move the stops 13 away from the blade edge. In such position of the parts of the seat 111 of blade holder 1 will be located, at one end of the holder in juxtaosition to the endmost blade of the stack in magazine 8, so that when the ejector 11 is pushed to the right in Fig. 11 the said blade will be slid from the magazine into holder 1 between the seat 1a and the member 3, discharging a blade from holder 1. The magazine is shown provided, on the side of the blade holder opposite the chamber or space 8a, with a blade-receiving chamber 21 to receive blades discharged from the blade holder, so that the discarded blades will not have to be handled by the user. hen the blade holder is removed from the magazine the spring 18 will cause the member 14 to be tilted on its pivots for engagement of the stops 13 with the blade edgetending to position the blade in the holderin the manner before described. The spring 18' in Fi s. 10 to 12, is shown inthe formof a cod spring located in the bore 6 in handle 6 j In accordance with my invention a supply of blades may be maintained in position to be inserted successively, as desired, in a safety-razor blade-holder in such a manner' that the blades need not be individually inserted' in the holder 1 by the user. When the magazine is empty a supply of blades may be inserted therein w1thout requirement for further handling of the blades. An advantage of my invention is that the magazine for blades and the blade holder may be assembled in cooperative relation for insertion of a blade in the holder 1 without requiring the magazine or stack of blades to be maintained upon or in connection with the razor when the latter is to be used for shaving, since the magazine and the blade holder may be so arated for use. By the means described the stack of blades will not be subjected to wetting when the blade holder is washed, thereby avoiding rusting of the blades.
