PARK, ILLINOIS, ASSIGNOR TO THE ELECTRO AUTO- MATIC SAFETY RAZORA COMPANY, OF ORANGE, CALIFORNIA, A CORPORATION OF CALIFORNIA.
SAFETY-RAZOR.
Specification of Letters Patent.
Patented Nov. 1:2, 1907'.`
Application filed April 22. 1907. Serial No. 369.496.
To all 'whom it may concern:
Be it known that I, ISAAC N. BRIGHAM, a citizen of Canada, residing at Melrose Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare that the following is a full, clear, and
'i exact description of the same, reference being had to tion on line 5 5, Fig. 3. Fig. 6 is a longitudinal section on line 6-6, Fig. 3. Fig. 7 is a View showing the connecting end of the power shaft. Fig. 8 is a detached view of one oi the blade-clamping nuts.` Fig. 9 is a detached view of the pintle driving head. Fig. l0 is a detached view of the lower blade clamping plate. Fig. Il is a detached view of the blade. Fig. l2 is a detached view of the upper clamping plate and its blade-holding screws. Fig. 13 is an enlarged transverse sectional view showing one of the guard fingers in proper relationship with reference to the blade.
The present invention has relation to safety razors, and it consists'in the novel arrangement hereinafter described and particularly pointed out in the claims.
Similar numerals of reference indicate corresponding parts in all the figures of the drawing. I
In the accompanying drawing, 1 represents the housing,Ik which is substantially of the form shown in the drawings, and as shown it is provided with the hollow connecting shank 2,' which is internally screw threaded for the purpose hereinafter described. The housing l is provided with the guard fingers 3, which. guard fingers-are curved at their outer ends so as to provide a smooth contact surface. The housing l is provided with .shoulders or what might be `termed guide ways 4, which are for the purpose hereinafter described. The housing 1 is formed of comparatively thin material and is stamped yor bent into the form shown. The razor blade 5 is formed of sufficient thickness to prevent any springing, bending or buckling and its edges beveled so as to produce razor edges uponboth sides of the blade.
For the purpose of providing means for carrying the blade and clamping the blade the clamping plates 6 and 7 are provided which clamping plates are located upon portions of the opposite faces of the blade 5 as best illustrated in Figs. 1, 4, 5 and 6.
l -The shank 2 is connected to the motor casing 8by means of the screw threaded extension or shank 9, which shank may form a bearing for the armature shaft 10, which armature shaft is provided with the reduced portion l1, upon which reduced portion is located the driving headl l2, which driving head is rotatably connected to the armature shaft l0 in any convenient and Well known manner but preferably by means of the key l3-and the groove 13, but I do not desire to be confined t`o any particular way of connecting the driving head, owing to the fact that it is simply mechanical. The driving head l2 is provided with the pintle 14, which pintle is extended through the elongated slot l5 formed in the clamping plate G. The slot l5 is located at right angles to the plate 6, and is so located for the purpose of imparting a reciprocating movement to the plate 6 and the different parts connected thereto. The plate G is `provided with the apertures 16 .through which apertures the clamping bolts 17 are passed, said clamping bolts also passing through the apertures-18 formed in the blade 5. The clamping bolts I7 are for the purpose of connecting together with the plates 6 and 7 and the w blade 5, said parts being securely clamped by the nuts 19 or their equivalents. i
For the purpose of providing guide Ways for the clamping plates 6 and 7 the casing is provided with the guide ways 4 and 20, which guide ways will prevent any lateral movement of the clamping plates 6 and 7 and the razor blade 5.
In use I prefer to form the housing l of a single piece of metal, in order to provide a more rigid structure and hence it is necessary to form the end guards 22 by bending the metal into the form illustrated in the drawings, thereby leaving the ends of the housing in a rigid condition.
` The clamping bolts are provided with the enlarged portions 23, which enlarged portions are formed of a size to correspond with the size of the apertures 18 formed in the blade 5 and are so formed for the purpose of bringing the razor blade 5 into true alinement with the guide ways 4 and 20 said blade being held in true I alinement with the outer edge or curved surface of the guard fingers 3 by means of the guide ways formed in I the casing and the clamping plates 6 and 7. l
It will be understood that -there can be no relative movement as between the clamping plates 6 and 7 and the blade 5 when the clamping bolts have been properly connected so as to clamp the razor blade 5 between said plates. In razors of this c'lass it is of importance that there be no perceptible-variation at any time as to the distance between the cutting edges of the razor blade and the guard ngers.
It Will be'understood that by this peculiar arrangement the razor blade will reciprocate in true parallelism with .the guard fingers or in other words the razor llade will be held in true and exact alinement at Jall times and under all circumstances with the guard fingers. For the pu pose. oi providing a means for easily detaching the blade from the clamping plates 6 and T said clamping plates arel provided with the recesses 24, which recesses provide room to insert the end oi the finger to disconnect the parts. v
Having fully described my invention what I claim as new and`desire to secure by Letters Patent, is-y 1. ln u po\ver drivenrsafety 4 with luide ways, a razor blade, clamping plates located upon opposite sides or' the lrazor blade, one of said clampingl plates provided with a longitudinal slot, a power shaft provided with a detachable/'Y driving head, said drivingv head provided with a pintle adapted for engagement with the .elongated slot, means for clamping'thdrazori'blade :ind plates `together'aud the housings provide lingers, substantially as and foi` lthe purpose specified.
A2. In a power driven safety razorf/tlie combination of a driving shaft, a casing provided with guide ways and curved guard fingers', a razor blade and clamping plates, said razor blade located internediate the clamping plates, and means for imparting reciprocating movement to the razor blade and clamping plates, substantially as and for tlie'purpose specified.
In a power driven safety razor,
o. the combination of with guardi "i i razor, a housing provided yblade and guided by a casing providedwith guide ways and guard ngcrs, a razorblade, clamping plates, saidV razor blade located between said clampingplates. said razor blade provided with apertures, clamping adapted to'fit the apertures in the razor blade and menus for imparting a reciprocating movement to the razor blndv, substantially :is and for tliepurpose spcciicd.
1. In a power driven safety raiaor, a motor, a casing connected io said motor said casing provided with guide ways, a razor blade, clamping plates located upon opposite sides of the razor the guide ways of the casing, and
means for imparting; a reciprocating movement to the razor blade and clamping plates, substantially as and for v40 the purpose specified. y
Inla safety razor, .thecombination of a easing provided with guard fingers clamping plates, means for clamping the razor blade and clamping' plates together, said clamping plates provided with recesses :it their ends, substantially as and for the purpose spcciliod. I
