LAMP.

Specification of Letters Patent.

Application filed September 17, 1914. Serial No. 862,184.

To all whom it may concern.'

Be it known that I, FRED C. HOWE, a citizen of the United States of America, residing in the city and county of New Haven, State of Connecticut, have invented certain new and useful Improvements'in Lamps, of

l which the following is a specification.

This invention relates to a utility lamp, especially adapted to be carried upon automobiles, motor-boats, and the like, and aims to provide improvements therein.

The present invention provides a lam which is adapted to be turned so as to d1- rect its rays in any and all directions, as over the earth or sea, or sky, for searching out objects, or be directed upon parts of the Vehicle and its vicinity for making examinations or repairs.

The invention further provides a device which can be manipulated by a handle within the convenient reach of the operator of the vehicle, and which can be manipulated by a simple rotary movement of the handle, or combination of such movements.

Other features of advantage and importance will be hereinafter set out.

An embodiment of the invention is illustrated in the accompanying drawings, wherein- Figure 1 illustrates .the improved lamp a plled to an automobile; Fig. 2 is a side elevation of the device, with parts in section; Fig. 3 is a top plan view of the device; Fig. 4 is a longitudinal section of the handle-end of the device, and showing the manipulation of the device; Fig. 5 yis a front view; Fig. 6 is a section on line 6-`6, Fig. 2; and Fig. 7 is a section on line 7-7, Fig. 2.

Referring to said drawings, numeral 1 designates a lamp of any suitable kind or construction, and 2 its base or support. The lamp support is preferabl in the form of an arm or bracket 3, carried upon a sleeve 4 swiveled in a suitable bracket 5, b which it may be attached to the automobile body or other structure to whic the lamp is applied. The lamp is swiveled upon the arm 3, as atb, and is preferably ada ted to turn through an angle or arc of 360 egrees. The swiveling of the lamp support or base is preferably such that it also may be turned through an arc or angle of 360 degrees `in a plane at right angles to the axis of the lamp. A handle 7 which is conveniently accessible to the operator in his seat, is provided for turning the lamp, and also the lamp base or support 2. The handle oper- Patented J uly 27, 1915.

ates upon the lamp through a shaft 8 and `a suitable transmission such as miter-gears 9, fixed upon the shaft 8, and 10, on the axis of the lamp. The handle 7 operates upon the lamp support through a suitable clutch 11, which may be conveniently formed by nterengaging teeth or projections on the end of a projection or prolongation 12 of the sleeve 4, and on the end of a tubular projection 13 from the handle. The handle preferably slides upon the shaft 8 in such manner as to bring the clutch teeth thereon into and out of engagement with the clutch teeth on the part 12 of the lamp support. When the handle turns the lamp support 2, the pinion 9 is turned to the same degree so that the lamp is not turned on its axis during the turning of the lamp support. To prevent turning of the handle 7 on the shaft 8 the end 14 of the shaft 8 may be square, and the handle and the base of the tubular extension 13 may be provided with a corresponding square recess 15. A spring 16,1 bearing at one end against the handle and at its other end against a collar 17 on the shaft 8, normally pushes said handle out of clutching engagement with the lamp support 2. A friction device, suchas a split cupped washer 18, bearing against a shoulder on the sleeve 4, is preferably provided for restraining turning of the lamp sup ort in the bracket 7. Means are also pre erably rovided for lockingthe lamp support and) shaft 8 in one or more positions thereof, such means being a spring pressed finger-piece 19 having a projection 20 thereon adapted t0 enter slots 21, 22 in the sleeve extension 12 and the shaft 8 respectively. A casing 23 may be provided for the gears, and a weight 24 may be provided for counterbalancing the lamp 1.

Operation: The lamp being in the position shown in Fig. 2 can be turned on its axis so as to direct its beam in any direction within a radius of 360 degrees (Fig. 3) by pressing upon the finger-piece 19, so as to lift the projection 20 thereof from the slot 22 in the shaft 8 (but preferably not from the slot 21 in the sleeve extension .12), and turning the handle 7. Vhen it is desired to direct the light upbn a spot in another plane than that in which the lamp is shown in Fig. 2, the finger-piece 19 is pressed so as to withdraw the projection 2O from both slots 21 and 22. the handle 7 is pushed inward, against the tension of the spring 16, into clutching engagement with the sleeve extension 12 of the lamp support 2, and the handle turned so as to move the lamp support through a suitable angle or arc, as indicated in Fig. 5. The spring is then allowed to press the handle out of clutching engagement, and by then turning the handle the lamp can be swung through an arc of 360 degrees in the new plane. The lamp support being movable to any and all degrees within a circle, and the lamp being movable on its base or support to any degree Within a circle, it is possible to direct the beam of light in any and all directions, and upon substantially any desired object.

The invention may receive other mechanical expressions than those herein illustrated and specifically described.

What is claimed is 1. A Ydevice of the character described, comprising a lamp, a ivoted support for said lamp, said lamp eing pivoted on its support, a handle for moving said support and said lamp on their ivots, and a. clutch between said handle andp support.

2. A device of the character described, comprising a lamp, a pivoted support for said lamp, said lamp being pivoted on its support, a shaft adapted to turn said lamp on its pivot, a handle for turning said shaft, and a clutch between said handle and support', whereby said handle may also turn said support.

3. A device of the character described, comprising a lamp, a pivoted support for said lamp, said lamp bein pivoted on its support, a handle for moving said support and said lamp on their pivots, and a single means for locking said lamp and support against movement.

4. A device of the character described, comprising a lamp, a pivoted support for said lamp, said lamp bein pivoted on its support, a handle for moving said support and said lamp on their pivots, and a single means adapted to lock said lamp and support against movement, said means being also adapted to lock said support independently of said lamp.

5. A device of the character described, coinprisingia lamp, a pivoted support for said lamp, said lamp being pivoted on its support, a shaft adapted to turn said lamp on its pivot, a handle for turning said shaft, and a clutch between said handle and support, whereby said handle may also turn said support, said handle being slidable on said shaft for clutching said support.

6. A device of the character described comprising a lamp, a lamp-support, said lamp-support being pivotally mounted and said lamp being pivotally mounted on said support, a shaft for actuating said lamp and a shaft for actuating said lamp-su port, said shafts beingl coaxial, and a han le for operating said s afts, said handle being in constant operative connection with said lamp actuating shaft, and being adapted to to be moved into and out of operative connection with said lamp-support actuating shaft.
