NELSON H. FAIRWEATHEB, OF EVERETT, AND LEROY H. CROSBY, OF WALTHAM, MASSACHUSETTS; SAID FAIRWEATHER ASSIGNOR OF HIS ENTIRE RIGHT TO SAID CROSBY.
SAFETY RAZOB.
Application filed April 18, 1922. Serial No. 554,760.
To all whom it may concern:
Be it known that we, NELSON H. FAIR- WEATHER and LEROY H. CROSBY, citizens of the United States, residing at Everett and Waltham, respectively, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Safet Razors, of which the following is a speci cation.
This invention is embodied in a safety razor of improved construction, adapted to be carried in a garment pocket, when not in use, and to be readily converted into an gitudina edges of a head, the
operative razor, the construction being such that the blade-holding head may be stored in one end portion of the structure, and a plurality of blades in the opposite end portion.
Of the accompanying drawings forming a part of this specificat1on,-
Figure 1 is an end view of a razor embodying the inventgg n, adapted for use.
Figure 2 isa side view of the same.
Figure 3 is a side view of the blade.
Figure 4 is a fragmentary perspective view, showing a portion of the head.
Figure 5 is a longitudinal section showing the entire structure, including the head-con taining sheath hereinafter described, adapted for carriage in a pocket.
Figure 6 is a section on line 66 of Figure5.
Figure 7 is a section on line 7-7 of Figure 5.
The same reference characters indicate the same parts in all of the figures.
The head or blade-holdm portion of our improved razor is preferab y made from a blank of resilient sheet metal, bent to form a blade-rest portion 12, a guard portion 13, extending downward and forward from the rest portion, a resilient partially tubular neck 14, forming a socket portion, adapted to receive, the reinforcing back of the blade hereinafter described, and a clamping lip 15, which is normally held by the resilience of the neck in yielding contact with the rest portion 12. The socket portion or neck 14, and the uard portion 13, form opposite lonength of which is much greater than its width, or the distance between said longitudinal edges. The guard portion is apertured for the passage of lather through 1t, preferably by slots 17, as shown by Figure 4, so that the guard portion has a continuous lower edge. The
clamping lip is immediately over the ridge formed by the junction of the rest portion 12, and the guard portion 13.
Projecting inward from, and rigidly secured to the rest portion 12, is a shank 18, which is obliquely arranged or inclined relatively to the rest portion. The width of the head between the socket and guard portions is such that the head is adapted to be inserted in a cylindrical sheath 19, of a diameter suitable for carriage in a vest pocket, the longitudinal edges of the head bearing upon, or being in close proximity to opposite sides of the internal surface of the sheath, and the shank occupying a portion of the interior of the sheath at one side of the head, as shown by Figure 6. We are enabled by this arrangement, not only to enable a shank of suflicient operative length to be stored in a relatively small sheath, but also-to enable the shank when en aged'with a cylindrical handle'20, in accordance with our invention, to stand with the head inclined relatively to the longitudinal axis of the handle, as shown by Figure 2.
The handle 20 has a reduced portion 21 at one end, containing a socket 22, which is coaxial with the handle, and is adapted to detachably engage the shank 18, the socket and shank being preferably screw-threaded. The reduced portion 21 permits the insertion of the shank in the handle socket without contact between the guard portion and the handle, as shown by Figure 2.
The blade 22 is flat-sided, and has a single cutting edge 23, its opposite orback edge being inserted in a slot in a cylindrical reinforcing back 24. Said slot is formed to receive the back edge and minor portions of the sides of the blade, so that the major portions of the blade sides are exposed. The blade is therefore adapted to occupy a space of minimum width between the rest 12 and the clamping lip or ear 15. The back and blade are formed to be engaged with the head by sliding the back into the socket portion 14, and the blade between the rest portion 12 and the clampin ear 15. This operation expands the soc et and raises the car, which exerts a clam ing pressure on the blade. Displacement o the blade in all directions, excepting endwise, is-prevented by the he. To prevent acciden endwise displacement, we provide the back 24 with a positioning depression 26 (Figure 3), and form an inwardly projecting positioning boss-27 (Figure 1) on the socket wall, adapted to spring into the depression when the blade is in its operative position, so that endwise pressure on the back is regui to displace the blade from said osition.
The blade is narrow 1% its cutting edge projects sli htly forward from the rest 12, and over t e inner portion of the guard. 'lo permit the convenient removal ot the blade from the head, the back 2% 1s ag than the blade, so that its ends project from opposite ends of the socket suficicntly to form short handle portions 24, adapted to be grasped, these portions b6 preferably knurled, or otherwise corru etc The handle 20 has a tubu ar end rtion forming a cavity 29, adapted to receive several blades. A cap 30, forming an extension of said cavity, is removably engaged with the handle. The depth of the cavity 29 is such that when the ca is removed, rtions of the blades project t erefroin, so t at they ma be t and remov.
s here sown. the handle is adapted to contain three blades, which may be arranged as shown by Figure 7. llnjurious contact of the blades with each other is prevented by spacing members 32, which are separtitions fixed to the handle. A lining 33 of thin sheet cork, inserted in the cavity, prevents injury to the cutting edges of the lades.
It I now M seen that the head, the handl and the sheath constitute a safety razor structure, the head and a set of the blades of which are adap to be he in the handle and shea, these to :u structure adapted to be carried in a ,m -ut like a fountainn, and th adapted for use v a y ,i "i til shank We cl an:
