HAROLD Gr. EITZ GERALD, 01* LOS ANGELES, CALIFORNIA.
LAMP ATTACHMENT.
Application filed February 20, 1923.
To all whom it may concern.
7 Be it known that I, Harrow G. Frrz GERALD, a citizen of the United States, residing at Los i-ingeles, county of Los Angeles, and State of California, have invented a certain new and useful Lamp Attachment, of which the following is a specification.
My invention relates to device for regulating the movement of electric lamps, and more particularly it refers to a means, that may be in the form of an attachment, whereby the light of the lamp may be controlled.
The object of the invention is to provide a device for association with a lamp, by which the lamp may have an unrestricted vertical movement and an unrestricted horizontal movement, except within a definite area in order that a vertical movement of the lamp shall be necessitated to permit a continuous horizontal movement of the same.
Another object of the invention is to provide a control by which the light of a lamp shall be automatically extinguished when moved vertically in a certain area of its horizontal movement, but in which no interference shall occur with the circuit when the lamp is moved in areas other than previously determined for its extinguishment.
A form of device is shown in the accompanying drawing.
Fig. 1 is a side view showing a lamp and its mounting and the operative position of a circuit breaker, and Fig. 2 is a section on line 2-2 Fig. 1.
An association of my invention with a lamp of spot-light style and construction is shown at 1, and comprises the usual parts as the reflector 2, and the electric light, not shown. A support 3, provides a pivotal mount for the lamp which may have a vertical movement in said support, and the pivotal mount is formed with a post 4, arranged to be clamped by bracket members 5, in which said post may have a horizontal movement. The lamp thus has substantially a universal movement with an unrestricted vertical movement and a horizontal movement unrestricted, except in a definite area and by the means described as follows:
On the bracket 5, is a support 6, in which is secured in any suitable manner, a socket member 7, the bottom 8, of which is pro vided with a central opening 9, for the accommodation of a spring-pressed stem 10, to which is attached a contact member, generally shown at 11. This contact member is Serial No. 626,207.
connected with one terminal of the lamp socket, not shown, by a wire 12, and the other terminal of said socket is connected with a battery 13, by a wire 14. The bracket 5 is also included in the electric circuit by being grounded through wire 15, and obviously when the contact member 11, is in normal engagement with the bottom ofthe socket member 7, the circuit will be complete and tne beam of light projected from the lamp. Such normal position of contact is insured by the spring 10 coiled about the reduced portion 10 of the stem 10, which projects above the socket member 7, and in the path of the horizontal swing or move ment of the lamp, and specifically of an extension 16, provided on the lamp. The horizontal movement of the lamp in the plane of the projecting stem is impossible, but a hori zontal movement in a plane higher than that of the stem is possible, and such movement may be accomplished by vertically moving the lamp, whereby the extension lti, may escape contact with the stem. Should a vertical movement of the lamp downwardly be made while the extension is in line with the stem, the stem will be depressed with the resultant efiect of interrupting the circuit and extinguishing the light.
The aforesaid contact member 11 is preferably associated with the reduced portion 10 of the stem 10, by a screw 17, and may comprise the parts illustrated, to wit, a hollow metal body, constituting essentially the contact member 11; a metallic annulus 18, in contact with said metal body, to which the wire 12 is connected; an insulating disk 19, a washer 20, and suitable rings 21, for insulating the metal body and annulus from the screw 17.
It will be obvious that, with this arrangement, no beam of light from a lamp with which this arrangement is associated, can be projected straight ahead at any height, above the level of the ground, prohibited by law, and that a free and universal movement of the lamp outside of a defined area is not impaired.
What I claim is: V
1. A lamp, a universal mount for same, to enable the lamp to swing horizontally and vertically, an electric circuit including the lamp and mount, means to prevent horizontal movement of said lamp past a certain point comprising a yielding stop member, a
support for same in said circuit, and a contact member on and insulated from said stop member, said stop member operable by the vertical movement of said lamp to move said contact member and interrupt the circuit.
2. A lamp, a universal mount for same to enable the lamp to be swung horizontally and vertically, means to limit the movement of said lamp in a certain plane of its horizontal swing, comprising a stem, a support for said stem, a contact carried by and insulated from said stem, an electric circuit including the lamp, support and said contact, said stem operable by the vertical. movement of said lamp to move said contact and break the circuit, thereby extinguishing the light.
3. A lamp, a bracket, a connection for said lamp carried by said bracket and arranged to enable said lam-o to swing in a horizontal and vertical direction, a socket on said bracket, a spring-pressed stem operable in said socket and carrying a contact, said. stem projecting normally in the path of and arranged to limit the movement of said lamp in a certain horizontal plane, and an electric circuit, including the lamp, bracket and contact, said stem and contact carried thereby operable by the vertical movement of said lamp to break the circuit and e tinguish the light.
4:. A lamp, a bracket in which said lamp may be moved vertically and horizontally, a contact, an electric circuit including said lamp, bracket and contact, and a means on said bracket to limit the movement of said lamp in a horizontal plane and operable by and when said lamp is moved vertically out or such horizontal plane to operate said contact and extinguish the light.
5. A lamp, a bracket in which said lamp may swing vertically and horizontally, a contact, an electric circuit including said lamp, bracket and contact, and a stop member to prevent the movement of said lamp in a horizontal plane, said stop member movable by the vertical movement of said lamp to operate said contact and extinguish the light of the lamp.
6. A lamp, a mount therefor providing a universal swinging movement for said lamp, an electric circuit including the lamp and mount, and means to restrict the movement of said lamp in a certain horizontal plane, comprising a socket member carried by said mount, a stem in said socket, a resilient means to press and hold said stem pressed beyond said socket and within the area of a certain plane of the horizontal swinging movement of said lamp, and a contact member on and insulated from said stop memher, said stop member operable by the vertical movement of said lamp to move the contact and interrupt the circuit.
In testimony whereof l have set my hand.
HAROLD G. FITZ GERALD.
