FREDERICK NATHANIEL DAVIDSON, OF LONDON, ENGLAND.
Specification of Letters Patent.
Patented Jan. 18,1916.
Application filed September 9, 1913. Serial No. 788,782.
To all whom it may concern:
Be it known that I, FREDERICK NATHAN- IEL 1)AVIDSON, a subject of the King of England, residingat London, England, have invented certain new and useful Improve ments in Razors, of which the following is a specification.
This invention is for improvements in or relating to razors and has for its object to enable the user to see clearly that portion of the surface to be shaved which lies immediately in front of the razor edge.
As is well-known various illuminating means have been provided for shaving purposes, one of which comprises a mirror having in it an orifice fitted with a lens behind which is an electric light so that a pencil of light is projected from the front of the mirrow through the'lens. This, however, necessitates that the surface to be shaved must be continually moved to keep that part which at the moment is under the razor in the pencil of light.
The present invention comprises a device constituting a source of light and adapted to be borne on a razor in such position as always to illuminate that portion of the surface to be shaved which lies immediately in front of the razor edge. More particularly an electric lamp bulb connected by a flexible wire to a source of electric supply is provided with means for securing it on the handle of the razor in such a way that it illuminates the razor blade and moreover together with the handle it forms a handhold by which to grip the razor. It will be seen that as the lamp bulb is connected to the razor, it will always follow the same, so that no movement of the person being shared is necessary to get the properillumination.
It has heretofore been proposed to mount an electric lamp on a pen or pencil so as to illuminate a small region about the point. No claim is made broadly to the use of an electric lamp mounted on some article to illuminate the place of operation of the article. nor is any claim made broadly to the particular means hereinafter described whereby the lamp is mounted on the razor so as to be adjustable with respect to it.
The socket for the lamp-bulb may be permanently attached to the razor or it may be carried by a clip which can be secured to any existing razor, the clip preferably being such as to permit adjustment of the socket of the lamp-bulb to permit of the bulb being brought to such position as to most advantageously illuminate the surface to be shaved.
The accompanying drawing isv a perspective view of a safety razor with a lamp-bulb attachment according to the present invention.
The lamp-bulb A is mounted in any convenient form of socket, which in turn is carried by a clip B adapted to spring on to the handle C of a safety razor and hold the lamp-bulb beneath one or other of the edges of the razor blade. From the lamp-bulb socket a. flexible wire 1) extends having a plug D at the other end for connection to a corresponding receiving-piece in circuit with a battery or other source of electric supply. In this form of the invention, the only adjustment possible is lengthwise of the handle to bring the lamp-bulb nearer to or farther from the surface to be shaved, but an adjustable arm pivoted on the clip so that it may be adjusted thereon may be provided to carry the lamp-bulb at its outer end if desired.
Although the invention has been described as provided with an electric lamp, it will be appreciated that any source of light of sufiicient illuminating power can be used instead of electric light.
It will be appreciated that the socket for the lamp-bulb A may be made integral with or permanently secured to the handle of the safety-razor if desired; other minor modifications will suggest themselves in connection with the apparatus shown, and all such modifications are considered to fall within the scope of the present invention.
\Vhat I claim as my invention and desire to secure by Letters Patent is:
1. The combination of a razor frame hav-v ing a blade holder and a handle approximately ..1181.penlic11l:i1' to the blade holder, an electric lamp socket extending parallel to said handle, means for securing the lamp socket to the handle at the side of the handle which lies beneath the blade edge when in use, an electric lampin the front end of the socket adapted to throw its light rays b ow the blade holder, and a flexible electrical conductor extending from the rear of the lamp socket, said lamp socket and handle forming a hand hold; substantially as described.
2. The combination of a razor frame havrays below the blade holder,
ing a blade holder and a handle approximately perpendicular to the blade holder, an electric lamp socket extending parallel to the handle, a clip for adjustably securing the lamp socket to the handle at the side of the handle which lies beneath the blade edge when in use, and arranged to permit the socket to be adjusted longitudinally along the handle toward and from the blade holder, an electric lamp in the front end of the socket and adapted to throw its light and a flexible electrical conductor extending from the rear of the lamp socket, said lamp socket and handle forming aihand hold; substantially 15 as described.
In testimony whereof I have signedmy name to this specification in the presence of two subscribing witnesses.
FREDERICK NATHANIEL DAVIDSGN.
