J. H. D. EVERETT SAFETY RAZOR Filed Sent. 4, 1923 mfm Patented pi'. 22, i;
JOHN H. D. EVERETT, QF SAULT STE. ll
Application led September 4, ,1928. Serial No. 660,688.
To all whom. it may concern:
Be it known that I, J oHN H. D. Evnnn'r'r, a citizen of the United States, and a resident of the city of Sault Ste. Marie, county of Chippewa, and State of Michigan, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.
VMy invention relates to new and useful improvements in4 safety razors, and has for its object to provide an improved const-ruction of this class which is particularly adapted for shaving hollow portions of the body, such as the arm pit, and the like; and
is durable in construction, highly eflicient in use and at the same time economical in manufacture.
Other objects will appear hereinafter.
The invention consists in the combinations and arrangements of parts hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawin j forming a part of this specification, and in which,
Fig. 1 is a plan- View of a blank from which my improved blade holder is formed;
Fig. 2 is a side elevational view of my improved safety razor;
Fig. 3 is a top plan view thereof;
Figs. et and 5 are vertical sectional views taken respectively on lines 4.-4 and 5 5 of Fig. 3; and
Fig. 6 is a view of the razor blade with its supporting jacket.
In manufacturin my improved safety razor the blade hol ing portion 8 and handle 9 are formed from a blank stamped or' cut from a single piece of material. preferably spring metal, and having an integral portion 10 for forming the handle, and di verging strips or arms 11 extending therefrom and each carrying oppositely arranged jaws 12 at the outer ends, said jaws bein connected by an intermediate bowed guar portion 13, which is integral with the jaws 12 and which contains serrations 14 flattened at the outer portions. The blank 10 is preferably constructed from spring steel and-is 5o folded on the longitudinally central line, shown by dotted lines in Fig. 1, and the arms bein@ curved upward and outward with the jaws extending arallel and the intermediate portion 13 eing bowed or curved outwardly as shown in the wings.
The jaws 12 are provided with lu s 15 which are bent over for engaging and olding the razor blade in positio-n.
The razor blade 16 is referably made of spring `steel and is bowe or curved in conformity with the curvature of the bowed portion 13, substantially in the form of a sector or quadrant of a circle, and is provided with projections 17 at each end and a notch 18 therebetween. A reinforcin 65 member or jacket 19 is folded or double over and clamped over the dull edge ofthe razor blade extending over a portion of the outer face of the razor blade as shown at 20 and extending over the larger part of the inner face of the razor blade as shown at 21, said jacket being curved in conformity to the blade and possessing suiiicient rigidity to substantially retain the blade in its proper bowed shape. Lugs 22 are provided on each 75 end of said jacket and are curved over the edge of the projections, 17 of the blade to prevent the blade from withdrawal from the jacket, and for reinforcement. p
In mounting the blade with its jacket on a0 the blade holder the resilient arms 11 are slightly bent apart and the bent over lugs 15 of the holder are engaged in the notches 18 of the blade, and are seated between the projections 17 of the blade and the lugs 85 22 of the jacket, thereby positively and firmly holding the blade in position. ln order to support the razor blade and positively retain it-in its outwardly bowed position, an elongated tooth 23 is provided, 90 on the bowed guard portion 13, preferably at the middle part thereof, and the point of this tooth engages beneath the inner face of the blade thereby spacing it slightly above the attened faces of the teeth or serrations 14, and projections 23 are also provided adjacent the ends of the portion 13 and assist the tooth 23 in preventing the blade from descending upon said flattened faces of the serrations. a
It is apparent from the above disclosure that this form of construction, with the use of the' jacket and the raised tooth, retains the blade in its roperly curved or .bowed shape` and that t e resilient arms with the ma lugs 15 thereon firmly and positively retain the blade with its jacket in proper shaving position and at the same time permit convenient removal of said blade from the holder. lt is also apparent that the device ma provides a very edective and efficient razor for shaving hollow portions of the body such as the arm pit.
While I have illustrated and described the preferred form of construction for carryin my invention into effect, this is capable o variation and modification without dep-arting from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
Having described my linvention what I claim as new and desire to secure by Letters Patent, is:
1. In a safety razor, the combination with a bowed cutting blade having a notch provided in each end, of a holder for said blade and comprising a handle with means for engaging in said notches to hold the blade in position, and a serrated member under said blade and containing an elevated serration engaging the under face of said bowed blade to prevent it bending onto the other serrations.
2. In a safety razor, the combination with an outwardly bowed cutting blade having a notch provided in each end intermediate the corners, of a holder for said blade and comprising a handle with diverging members containing jaws with means for engaging said notches to hold said blade in position, and a serrated member joining said jaws and containing serrations located slighlty beneath said blade, and an elevated tooth engaging the 'under face of said bowed blade to prevent it bending onto the other serrations.
3. In combination, a safety razor comprising a bowed blade, a reinforcing jacket doubled over an edge of said bowed blade and engaging both faces thereof to retain said blade in curved shape, means on said jacket to hold said blade therein, a notch formed on each end of said blade between said means, and a handle with means engaging in said notches to hold said blade in po-v sition.
4. In combination, a safety razor comprising an outwardly bowed blade, a reinforcing jacket doubled over the back edge of said blade and engaging both faces thereof to retain it in its bowed shape, lugs on said jacket bent over the ends of said blade, a notch formed between said lugs, and a handle having side members with a serrated portion extending beneath said blade and having side lugs engaged in said notches to hold said blade in position.
5. A safety razor holder formed of an innannten tegral connected blank, comprising at one end a handle portion doubled centrally upon itself and at the other end a transverse upwardly bowed guard portion, the ends of the guard portion being connected with the handle portion by curved separate arms, said arms being bent up at the ends of said guard'to form spring clamping jaws to yieldingly clamp the bowed ends of a razor blade therebetween, and a tooth on said bowed guard portion for engaging the inner faces of said razor blade.
6. In combination, a safety razor comprising a blade holder formed from a blank punched from a single piece of material, said blank being folded centrally to forni a handle portion and to form separated arms with jaws thereon, an outwardly bowed serrated guard portion connecting said jaws, a bowed safety razor blade having notches in its ends, a reinforcing jacket mounted over said blade to retain it in its curved position, lugs on each side of said jaw for engaging said notches to hold the blade in position, said arms being resilient to ermit convenient insertion and removal o said blade, and an elongated tooth on said bowed serrated portion engaging under the inner side of said blade to retain it in its bowed position.
7. In a safety razor, the combination with an outwardl bowed cutting blade, of a holder for said blade and comprising a handle with resilient means for engaging the ends of said blade to hold it in position, and a serrated guard member connecting said blade engaging means and spaced slightly beneath said blade, said member being curved to correspond to the curvature of said blade, and elevated means on said serrated member for engaging the under face of said bowed blade to prevent it bending onto the other serrations.
8. In combination, a safety razor comprising an outwardly bowed blade, reinforcing means mounted on said blade, and bowed to correspond to the curvature of said blade for retaining said blade in its bowed shape, means on said reinforcin means to retain said blade firmly in position therein, and a handle with means for mounting and retaining said blade and its reinforcing means in bowed position therein but permitting convenient removal thereof from said handle.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
