EMOBY D. FINCK, OF ATLANTA,
NEW YORK.
AUTOMOBILE-SIGNAL.
Specicaticn of Letters Patent.
Patented Dec. 19, 1916.
Application led August 18, 1914. Serial No. 857,359.
To all whom it ma concern:
Be it known that I, EMORY D. FINCH, citizen of the United States, residin at Atlanta, in the county of Steuben and tate of New York, have invented certain new and useful Improvements in AutomobileSignals, of which the following is a specification.
My present invention relates to an auxiliary circuit for a portable electric hand light, such as may be conveniently employed about motor vehicles in case of trouble, this auxiliary circuit including a detachable plug and socket connection between the light cord of the portable light itself and the permanent wiring of the vehicle.
One object of my invention consists in making up the wires of the auxiliary circuit in the form of an expansible cable and in roviding means for locking the plug and soc et connection against separation so that this cable may be stretched when in use.
With these and other objects in view, my invention will be more fully described, illustrated in the accompanying drawing, and then s ecifically pointed out in the claim which is attached to and forms a part of this ap lication.
he drawing is a view of the portable light, together with its plug socket connection, the latter being shown in section.
Corresponding and like parts are referred to ,in the following description and indicated in the drawing by the same reference characters.
I have shown my invention in connection with a portable electric light 23 havingwires 24 and 25 leading to a plug and socket con.
nection 26 from which wires 27 and 28 lead to any suitable source of energy. The plug and socket connection may be secured in any part of a vehicle body, in the present case bein illustrated as applied to the vehicle das 29. This connection includes a cylindrical socket member 30 formed of insulating material and carrying spaced contact members 31 to which the Wires 27 and 28 are permanently connected. These contact members are preferably in the form of cylinders provided at their free ends with sockets 32 which open through the outer face of the socket member 30. Co-acting with this socket member is the plug member 33, the body of which is also formed of insulating material and which carries the contact members 34 to which the wires 24 and 25 are connected. The free ends of these contact members, which are in effect pins', project beyond the outer face of the plug member 33 in such ya manner that they may be inserted in the sockets 32 of the socket member, as clearly shown. One or the other of the members 30 and 33, in the present case the member 33, is provided with a spring catch 35 having a hooked terminal 36 adapted to seat in a notch 37 formed in the other member, when the members are connected to prevent accidental separation of the members. This is of considerable importance as otherwise the two connecting members are apt to be separated by undue pulling upon the wires 24 and 25 during manipulation of the prtable lamp 23. This lamp is preferably provided with a handle 38 by means of which it may be conveniently carried from place to place and with a protective cage 39 of relatively stiff wire to keep the light bulb from injury. The wires 24 and 25 are, of course, of the insulative type and are preferably formed of resilient wire wound in helixes, one helix being disposed within the other in such a manner thatthe resultant cable 40 may be stretched longitudinally to a considerable extent.
In operation, the portable hand light may be connected by inserting the pins 38 of the plug member into the sockets 32 of the socket member and the light may then be readily moved to any part of the vehicle. This is of particular importance, in view of the fact that under many circumstances the employment of oil or acetylene lights or the lighting of matches about the vehicle might be dangerous. The lock for the plu and socket connection prevents accidenta disconnection during use and the peculiar cable construction of the current carrying wires avoids practically all likelihood of breaking the wires under excessive strain.
It will of course be understood that I reserve the right to make any changes, within the scope of the a pended claim, which may be found advisab e, without in the slightest degree departing from the spirit of my invention.
Having thus described the invention, what is claimed as new is:
In an electrical apparatus, a cable including supply and return conductors, each being in the form of a resilient and insulated wire Wound in a, helix, `with the helix of one In testimonywhereof I ax my signature disposed Within vand throughout the length in presence of two Witnesses. of the other, the resiliency of the wires nor- EMORY D.
