To all whom it may concern:
'Be it known that I, CARL Gnsrnv Sonne- KAT, acitizen of the Unite States, residing at Fremont, in the county of Sandusky, State of Ohio, have invented certain new and useful Improvements in Safety-Razors; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures or" reference marked thereon, which form a part of this specification.
This invent-ion relates to razors of the safety type, wherein a thin blade is movably held in position with its cutting edge adjacent a guard which projects beyond the edge of the bladetto prevent cutting the face, it being customary to furnish with razors of this type a number of blades so that when a blade becomes dull, a sharp blade may be quickly substituted therefor; and the invention consists in the construction and arrangement of parts hereinafter more fully set forth. and. claimed.
The primary object of the invention is to produce a razor of the character described, of comparatively simple and inexpensive construction, wherein the arrangement is such as to enable a blade having two cutting edges to be supported in amanner to render it adaptable for use, and at the same time enable the blade to be easily inserted and quickly removed.
A. 'further object is to provide means for supporting a blade having two cutting edges without injury to the cutting portion of .either edge of the blade, and in a manner to enable the blade to. be readily handled for insertion and removal without danger of cutting the hand. I
A further object is to provide a holder for the blade of such construction that the blade shall be supported at its ends only, the intervening portionof the frame between the supporting ends which carries the guard teeth, being, depressed so as to afford a space between the edge of the blade and the guard for the passage of hair and lather, the blades employed being sufficiently rigid to render them operative for shaving without any support except at their extreme ends.
A further object is to provide means for positioning the blade in the holder and maintainin the cuttin edo'e thereof alb b 0 ways straight with theguard.
A further object is to provide means for holding the blade yieldingly in place with sufficient force to prevent movement of the blade during the operation of shaving.
The above objects are attained by the structure illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a razor embodying my invention, showing the blade in position. Fig. 2 is a side elevation thereof. Fig. 3 is an enlarged sectional view throughthe blade, the supporting-plate or frame and the guard, as on line 3-3 of Fig. 1. r Fig. 4: is a top plan view ofFig. 1. Fig. 5 is a similar view showing the position of parts during the operation of removing or inserting a blade. Fig. 6 is a top plan of the blade-supporting plate with the blade removed. Fig- 7 is a perspective view of the spring which is mounted onthe back of the supporting-plate or frame and carries on its ends the angle brackets which engage the rear corners of the blade and through the tension of the spring force the forward edge of the blade against the stop lugs on the end portions of the spring frame. FigfS' is a rear elevation of the razor. Fig. 9 is an end elevation of the blade. Fig. 10 is a longitudinal section as on line.'l010 of Fig. 4:.
Referring to the characters of reference, 1 designates the handle, of any suitable construction, having a reduced threaded stem 2. The frame or blade-holding plate Ei'is oblong and quadrangular in form, having a dependin back portion 4 terminating in a reduced orwardly extending part 5 which is provided with a tapped aperture to receive the threaded stern of the handle-where by the supporting-plate may be detachablymounted on the handle, as shown. The central portion of the supporting plate is depressed, as shown at (S, leaving the end portions 7 of said plate above the plane of said depressed portion. The forward edge of the depressed portion-of the plate between the supporting end portions 7, is provided'with a plurality of teeth or downwardly curved fingers 8 which form a guard that prevents the edge of the blade cutting the face, as will be well understood in the art. By 'depressing the guard portion of the supporting-plate between the end portions 7 thereof, a space 9 (see Fig. 3} is formed between the when said blade is placed upon the supporting-plate, whereby the blade may be held employed having the centrally depending to theback 4 of the supporting-plate.
plane of said plate, as shown.
are not dulled or injured by the means of inserting it in or removing from the concaved, as shown at 17 in Fig. 6. to facili tatc the handling of the blade in the manner f guard and the edge of the blade 10 when said blade is in position for shaving, affording a free passage for the hair and lather andpreventing the clogging of the lather between the guard and the edge of the blade, a result common in razors of this type where the blade rests directly upon the guard. An accumulation of lather between the teeth of the guard and the edge of the blade holds the blade from contact with the face and renders the razor inoperative until said accumulation is removed.
Upon the end portions 7 of the supportingplate at their outer edges are formed the' stop lugs 11 under which the forward edge of the blade at the corners is adapted to engage, whereby the blade is caused to stand in alinement with the guard and is held in proper relation thereto. For the purpose of pushing the forward edge of the blade against the stop lugs 11, a spring arm 12 is ear 13 which is riveted or otherwise fastened Said spring arm extends transversely across the back of the supporting-plate and its end portions are curved forwardly, as shown at 1%. Each of the forwardly curved end portions of said spring is provided with a vertically extending cornpr bracket 15. Said brackets lie in the right-angle recesses 16 formed by cutting away the rear corners of the supporting-plate and extend above the The shape of said brackets is such as to cause them to embrace the rear corners of the blade only at its corners, and at the same time properly positioned longitudinally. The distance between the stop lugs 11 and the brackets 15 is less than the width of the blade, so that to place the blade in the holder its rear corners are caused to engage in" said brackets, when by applying a rearward pressure to the blade, the spring arm 12 will yield sufiiciently to allow the forward cor-. nersiof the blade to engage under the stop. lugs 11, when by releasing the blade, the ten sion of said spring arm will crowd it forward against said lugs and'hold it with sutiicient tension to maintain it in place during the ope- "ion of shaving. It will be noted that tl stop lugs and the spring sup ported brackets the blade only at the corners so that the cutting edges of the blade which holds the blade in place.
in. manipulating the blade for the purpose frame or holder, it is grasped at the between the thumb and finger, the end portrons (if theholder or sup portingplate being stated. By this arrangement a blade with parallel cutting edges may be readily hell in a manner to enable the blade to be. easily reversed when one edge becomes dull, thereby rendering the blade doubly serviceable with comparatively little additional expense,
the arrangement for holding the blade beingsimple and inexpensive and of a character to prevent injury to the edge not in use while said blade is being held in operative position in the holder. The pressure e2:- erted by the end portions of the spring arms against the rear corners of the blade is such as to crowd the blade forward against the stop lugs, thereby obviating the possibility of the cutting edge of the blade being held at an angle to the guard, and insuring a perfect positioning of the blade under all conditions.
Having thus fully set forth my invention what I claim 'as new and desire to secure by Letters Patent, is
1. In a razor, the combination ofa bladeholding member having a guard along one edge, a blade having parallel cutting edges, stops upon the blade-holding member adapted to engage the forward corners of the blade for alining said blade with respect to said guard, a spring arm mounted on the back of the blade-holding member having brackets at its ends to engage the rear corners only of said blade and press the blade forward against said stops, said brackets having engagement also with the ends of the blade to prevent. longitudinal moven'ient thereof on the blade-holding member.
2. In a razor, the combination of a bladeholding member having an immovable guard along one edge, a blade having paral .lel cutting edges, the blade-holding member .having stops at its forward. edge to engage the front edge of. the blade at its corners only and aline said blade with respect to said uard, a spring arm fastened at its center to the back of the blade-holding member the free ends of said arm being formedto engage the rear corners only of the blade and carry the forward corners thereof against said stops, said engaging ends of said arm preventing longitudinal movement of the blade while carrying said blade into operative position.
