SAFETY RAZOR Original Fild Nov. 26, 19 28 INVENTOR MM ATTORNEY Patented Feb. 9, 1932 UNITED STATES HENRY J. GAISMAN, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, T0.

PATENT OFFICE GILLETTE SAFETY RAZOR COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF DELAWARE SAFETY RAZOR Application filed November 26, 1928, Serial No. 321,793. Renewed February 24, 1931.

holder serving to discharge a used blade therefrom.

An object of my invention is to provide blades of such a shape that they will cooperate with complemental portions of the blade holder for maintaining proper shaving position while being inserted into the holder without injury to the cutting edges of the blades, my invention being particularly aplicable to double-edged razor blades.

Another object of my invention is to provide a clip or retainer for a stack of blades, which may be inserted in a magazine to retain the blades therein with their cutting edges out of contact with the magazine and in position to be pushed into the blade holder. My invention comprises novel detailsv of improvement that will be more fully herein-' after set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part hereof, wherein Fig. 1 is a perspective view illustrating my improved razor in position for use;

Fig. 3 is a similar view illustrating the blade shaped for use;

Fig. 4 is a partly vertical section through an %z 1g. 5 1s a cross section of the blade holder of Fig. 1;

Fig. 6 is a partly sectional side view, illustrating the blade holder in position to receive a blade from a magazine;

Fig. 7 is a lon itudinal section illustrating the position of t e parts when a blade is being inserted into the blade holder from the magazine;

Fi 9 is a cross section on line 9, 9, in Fig. Fig. 10 is a. sectional detail of the razor 5Q- handle;

gig. 11 is a perspective of the blade clip, an v Fig. 12 is a perspective view illustrating a stackof blades in the clip.

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

A blade holder 1 is shown pivotally connected at 2 with a handle 3. The holder 1 is 'shown provided with a longitudinal recess 1a in one side in which the reduced end portion 3a of the handle is pivoted, so that the holder may be turned to the shaving position relatively to the handle, as shown in Fig. 1, and the holder may be turned to a position in alignment with the handle to receive blades 4 from a magazine or chamber 5 in the handle, (Fig. 7). The blades are shown of the variety having two cutting edges, and the blade holder is shown provided with spaced seats or guiding portions 6 upon which adjacent portions of the blade rests when sliding'into and in shaving position in, the holder. The blade holder is also shown provided with guards 7, on opposite sides beyond the seats 6, and with blade retainers 8 over the respective seats, (Figs. 1 and 5). The retainers are resiliently supported by springlikearms. 9 extending from the blade holder, and so positioned as to provide guiding spaces 10 for the blades between the retainers and the seats 6. The blades are shown of permanent curvilinear or non-flat shape in the transverse direction between the cutting edges, (Fig. 8) and the seats 6 and the inner edges of the associate retainers 8 are shown located at an acute angle so that the marginal portions of the blade will be retained in the holder with the cutting edges projecting beyond the seats 6 adjacent to the guards. The holder is shown provided with a longitudinal rib 1?), between the seats 6, to engage the curved mid-portion 4 of the blade to guard the latter as it slides into the holder, to keep the blade edges out of contact with the holder. The curved mid-portion 4" of the blade and the rib 1b cooperate to retain the blade from edgewise movement and with the cutting edges of the blade in shaving relation to the guards. To form and retain the blades in the curvilinear shape shown the portions, indicated at 4a in Fig. 2, of metal sufliciently soft to permit the blades to be bent to the shape desired, the outer portions 4?) of the blade being properly hardened for the cutting edges.

The blades described are adapted to be placed in a stack or pile to be retained in the magazine 5 of the handle 3 in position to be pushed into the blade holder as required, (Figs. 7, 8 and 9). A clip for retaining the stack of blades within the magazine is indicated at 11. The clip 11 may be made of metal, having spaced sides 11a curvedtransverse connecting members 116, and inwardly bent or extending fingers 110. When the. stack of blades is slid into the. clip 11 the inner blade will rest against the members 116 and the outer blade willbe engaged by the fingers 110, the slip parts including the fingers preferably being resilient to flexibly.

grip the blades, and retain their cutting ed cs out of contact with the sides of the c 1p, (Fi s. 9 and 12). The sides of the clip 11 pre erably fit snugly against the side walls of the magazine 5, and the wall 12 of the mag azine is shown curved at 12a, substantially corresponding to the curvature of the blades,

so as to guide the latter as they are pushed out of the clip and the magazine into the blade holder and keep the cutting edges of the blade out of contact with the handle 3,

(Fig. 9

The clip 11 with its stack of blades is adapted to be inserted into the magazine 5 through the open side 5a thereof, (Fig. 10) A movable cover or closure 13 for the magazinc is shown pivoted to. the handle 3, at 14,

and a spring catch 15 is shown on the handle to keep the cover closed, (Fig. 7). A spring 16, which may be riveted on the cover 13, at 17, is adapted to bear against the blades within the magazine, tending normally to press said blades against the wall 12. The handle 3 is shown provided with an outlet opening at 18, through which the innermost blade may be pushed into the blade holder 1, (Figs. 7 and 10). An ejector 19 is slidably guided by the handle 3, in alignment with the outlet openlng 18, to push the innermost blade through said opening into the blade holder. The ejector is preferably curved to substantially conform to the curvature of the portion 12a of wall 12 and the curvature of the blades, (Fig. 9), whereby the ejector is slidably guided. The ejector is shown provided with a handle-like head 19a, adapted to abut against the outer end of handle 3 to limit inward sliding of the ejector. The ejector is also shown provided with an opening 19' adapted to receive a projection 2011 from a spring 20 that is located within a recess 21 in the handle, to limit outward movement of the ejector, (Figs. 7, 8 and 10). The projection 20a is shown inclined to permit the holder, an. ejector, and means to ejector to slide over the pro'ection on the blade-ejecting stroke of the e ector.

When a blade is to be inserted into the blade holder the ejector will be drawn outwardly (from a position over the stack of blades) and the innermost blade will be pushed into alignment with the outlet opening, against the wall 12, in front of the ejector. The ejector will be pushed inwardly thereby engaging the adjacent end of the last named blade and will push the latter through the opening into the blade holder, ejecting from the latter a used blade, in manner illustrated in Fig. 7. When the blade is being pushed from the magazine the curved portion 12a of wall 12 and the fingers 1100f clip 11 will guide the blade so that its cutting edges will not engage the clip nor the handle 3. When the blade is being pushed into the blade holder the angular seats 6 and the retainers 8, in conjunction with the curvature of the blade, as well as the rib 16, will maintain the proper shaving alignment or posi'-- tion of the blade respecting the guards of the blade holder, until the blade rests in its final shaving position, where said seats, retainers and rib will keep the blade in 1ts proper shaving position. During such sliding movement of the blade the seats, retainers and rib will maintain the blade edges free from contact with any parts of the blade holder, so as not to dull the blade ed es,'since the angular seats, retainers and rib eep the blade from sliding angularly or to either side of the shaving alignment or position.

My improvement will be found of particullar advantage in'the class of razors having double-edged blades, since neither of such edges should slide against metal to guide the blade to shaving position for fear of dulling the cutting edge.

improvements are not limited to the details of construction set forth, as the same may be varied, within the scope of the a pended claims, without departing from t e spirit of my invention.
