W. E. LAWSON. SAFETY RAZOR. APPLICATION FILED JAN. 14, 1913.
Patented Nov. 10, 1914.
Inventor Attorneys U ITED STATES PATENT OFFICE.
' WILLIAM E. LAWSON, F RAI-IWAY, NEW JERSEY.
SAFETY-RAZOR.
Application filed January 1 1, 1913.
To all whom it may concern Be it known that T, WILLIAM E. LAwsoN, a citizen of the United States, residing at Rahway, in the county of Union and State of New Jersey, have invented a new and useful Safety-Razor, of which the following is a specification.
The present invention aims to provide means for connecting the blade holding head of a safety razor with the handle thereof.
Another object of the invention is to provide novel means whereby the blade holding head may be connected with the handle for rotation, without effecting a separation of the blade holding members of the head, or the blade-holding head from, the handle, the construction being such that the cutting edge of the blade may be disposed at an angle to the handle or approximately parallel to the handle, thus permitting therazor, in the one instance, to be used as an ordinary safety razor, and permitting the razor, in the other instance, to be, used as a razor of common type, or as a compromise between the two types.
The invention aims, further to improve generally and to increase the utility of, devices of that type to which the present in vention appertains.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawing :Figure 1 shows the invention in front elevation; Fig. 2 is a side elevation; Fig. 3 is a longitudinal section, the handle being rotated through an angle of 90 degrees from the position shown in Fig. 1; Fig. 4 is a perspective showing the several constituent parts of the razor separated; Fig. 5 is a fragmental longitudinal section of the head engaging portion of the handle; Fig. 6 is a perspective showing a slight modification in the blade holding head; and Fig. 7 is a longitudinal sectional detail showing a slight modification in the socket portion of the handle.
lln carrying out the invention there is provided a handle 1 terminating in a laterally extended, tapered neck 2 terminating in a Specification of Letters Patent.
Patented Nov. 10, 1914.
Serial No. 741,987.
socket 3. A lug 4 or a screw 4 as shown in Figs. 5 and 7 projects into the interior of the ends of the guard, other openings 8 are formed. The opening 7 is of slightly less diameter than the diameter of the socket 3, so that the socket 3 may constitute an abutment for the guard.
The blade 9 preferably is a double edged blade and may be equipped with a longitudinal slotlO provided intermediate its end with an enlargement 11, the enlargement being located opposite to the opening 7 in the guard 5, when the parts are in cooperating relation. The precise manner of forming the openings in the blade 9 may be varied without jeopardizing the utility of the invention.
The blade carrying head of the razor further includes a transversely curved, resilient cap 12 provided with projecting pins let which, if desired, may be flattened upon opposite sides, as indicated at 15. Projecting from the cap 12 between the pins 14 is a boss 16 which is rooved circumferentially to form a neck 1 and to define ahead 18 located at the extremity of the neck. The head 18 is provided with a transverse slot 19. The slot 19 opens toward one end of the cap 12 and opens transversely of the shorter dimension of the head. When the screw 41*- is used the groove 25 only is employed the slot 19 being omitted.
In practical operation, the pins 14 of the cap 12 are engaged in the slot 10 of the blade 9, the boss 16 being located adjacent the enlargement 11. The pins 14 enter the openings 8 in the guard 5, and the head 18 of the boss 16 extends beyond the opening 7 in the'guard. The head 18 enters the socket 3 upon the handle 1. The lug 4.- which is located within the socket 3 is adapted to traverse the slot 19, then by rotating the handle 1, or by rotating the blade carrying head, the lug 4 will look behind the head 18 and thus hold the guard 5 and the cap 12 in clamping relation upon the blade 9. During this operation. the resilient, transversely curved cap 12 will be flattened out slightly, but the blade 9 will not be curved, the blade are separated, the blade 9 will not dropv away.
Attention is directed to the fact that the blade carrying head may be rotated upon the handle 1 so as to assume any desired angle with respect to the handle which the user vmay require. This operation takes place without causing a separation of the guard 5 and the cap 12, because the lug 41 is continuously engaged-behind the head 18.
Attention is directed to the fact that the slot 19 does not open toward either of the longer edges of the cap 12, neither does the slot 19 open toward either of the cutting edges of the blade 9. As a consequence, either of the cutting edges of the blade may be disposed inwardly and may be disposed transversely of the handle 1, as shown in Fig. 1, to permit the razor to be used after the manner of a safety razor. Further, owing to the location of the groove 19 it is possible to rotate the blade holding head until the cutting edge of the blade 9 lies approximately parallel to the handle 1. Under such circumstances, the razor may be used after the manner of an ordinary razor of the common and well known type.
It is obvious that the foregoing advantages may be secured by shifting the slot 19 and the lug 4 so that the lug is not opposite the-slot when either of the cutting edges of the blade lie parallel to the handle. V
Having thus described the invention,
what is claimed is In a safety razor, cooperating parts comprising a curved resilient cap and a handle, one of which cooperating parts is provided with a socket having a projection, the other of which cooperating parts is provided with a stud which is received within'the socket, the stud having a superficial transverse FRED W.
