DIBIGIBLE LAMP.
Specification of Letters Patent.
Patented Mar. 19, 1918.
Application filed March 10, 1917. Serial No. 153,843.
and EDWARD C. HUMPHREYS, citizens of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Dirigible Lamps, of which the following is a specification, reference being had therein to the accompanying drawings. o
This invention relates to dirigible lamps and has special reference to that style of lamp commonly known as a spot light used on an automobile or similar vehicle and adapted to be manually adjusted to cast rays of light in a desired direction.
The primary object of our invention is to provide a forked support, a trunnioned lamp in the support, and means extending through a portion of the support for adjusting the lamp therein.
Another object of the invention is to provide a lamp of the above type having .a support that may be rotated with the lamp held in the support and adapted for adjustment about an axis at right angles to the axis of the support, such adjustment permitting of light rays bein cast in a desired direction relative to the Front and sides of an automobile provided with, a lamp.
A further object of our invention is to provide a lamp and supporting means therefor so constructed that the lamp will have a universal movement, and novel means are employed for conducting an electric current to an incandescent bulb used as a source of light for the lamp.
The above are a few of the objects attained by our invention and reference will now be had to the drawings, wherein- Figure 1 is a side elevation of the lamp, partly broken away and partly in section;
Fig. 2 is a plan of a portion of the lamp support; and
Fig. 3 is a cross sectional view taken on the line III-III of Fig. 1.
In the drawings, the reference numeral 1 denotes a bracket that may be conveniently attached to the frame 2 of a windshield and mounted in said bracket is a horizontally disposed and normally stationary tubular arm 3, havin the outer end thereof provided with a clrcular hollow head 4. Extending into the hollow head 4 is the hollow head 5 on the tubular or hollow yoke having arms 6 and 7. The yoke head 5 has a central bearing 8 and mounted on said bearing is a tubular shaft 9 within the arm.3. The tubular shaft 9 terminates in a stepped hub 10 of a hand wheel 11 at the inner end of the arm 3, said stepped hub cooperating with the prevents accidental rotation of the hand wheel 11 and the tubular shaft 9.
J ournaled in the tubular shaft 9 is a shaft 13 extending through the bearing 8 of the yoke head 5 with a sheave 14 on the end thereof. A detachable plate 15 on the yoke permits of the sheave 1 1 being placed in position. The opposite end of the shaft 13 has a crank 16 and a hub portion 17 rotatable in the hand wheel 11. A spring pressed detent 18 carried by the crank 16 holds said crank against accidentalmovement relative to the hand Wheel 11.
Trunnioned in the arms 6 and 7 of the yokeis a lamp housing 19 provided with a solid trunnion member 20 and a tubular trunnion member 21. .The solid trunnion member 20 has a sheave 22 within the arm 6 and trained over this sheave and the sheave 14 is an endless cable or belt 23. The belt is In the lamp housing 19 is a lamp casing 28 containing a reflector 29, a lamp socket 30, and an incandescent bulb 31. The lamp casing 28 has a reel or drum 32 for an electric cable or conductor 33 which is wound on the reel with the innermost convolution thereof extending into the reel or drum 32 and connected to the lamp socket 30. The outermost convolution of the cable extends through the hollow trunnion member 21 and is connected to a disk 34. Engaging the disk 34 are resilient contact members 35 in the arm 7 and insulated therefrom, said contact members being connected to electric conductors 36 extending through the arm 7 and connected to binding posts 37 carried by the yoke head 5. The contact posts 37 have resilient contact members 38' engagin contact rings 39 on an insulator 4O mounte in the arm head 4;" The contact rings 39 have binding posts 41 and connected to said binding posts are lead-in wires or conductors 42 that extend through the hollow arm 3 and preferably through the bracket 1 and windshield frame 2 to a suitable source of electrical energy, as batteries (not shown).
The lamp casing 28 is detachable relative to the housing 19 and is held in engagement therewith by an ordinary bayonet slot and pin connection generally designated 43, and this connection is rendered more effective by a compression spring 44 mounted in the housing 19 and bearing against the reel 32 or the inner end of the casing 28.
To facilitate assembling the parts in the yoke arms 6 and 7 said arms have the ends thereof provided with detachable side plates 45.
From the foregoing it will be observed that by turning the hand wheel 11 the yoke head 5 may be rotated in the arm head 4 and in this manner the lamp turned in the longitudinal axis of the arm 3. By manipulating the crank 16, the lamp may be turned about the axis of the trunnions, thus permitting of all adjustments necessary for directing light rays from the lamp in a desired direction.
What we claim is 1. A dirigible lamp comprising an arm, a hollow yoke at the outer end thereof held for rotation about the axis of said arm, an electric lamp trunnioned in said yoke, means extending through said arm and a portion of said yoke adapted for shifting said lamp in said yoke, and means extending through another portion of said yoke for conducting an electric current to said lamp.
2. A dirigible lamp comprising a hollow yoke, an electric lamp trunnioned between arms of the yoke, means extending through one of the arms of the yoke adapted for shifting said lamp in said yoke, and means extending through the other arm of the yoke adapted for conducting an electric current to said lamp.
In testimony whereof we aflix our signatures in presence of two witnesses.
