BoAatsmRcH-LIGHT.

To all whom it may concern Be it known that I; CHARLES MANN, a citizen of the United States, and resident of Santa Ana, in the county of Orange and State of California, have invented new and useful Improvements in Boat search Lights, of which the following is a. specification.

The present-invention relates to searchlights, and more particularly those mounted for turning movement to direct the beam of light in various directions at will.

It is the object of the invention to provide a searchlight mounted for turning movement and having novel means of manual control, in order that the light can be readily moved in various directions by the simple manipulation of a handle. 1

Another object is'the provision of such a device which enables the searchlight orlamp located above the roof or deck of a boat or vehicle to be readily controlled from below,

in order that the light can be directed in different directions even though the lamp is on the exterior and the operator positioned within the cabin .or the like.

A further object is to provide controlling means for the searchlight so arranged that the turning movement of a handle will turn the lamp in a horizontal or other plane with a sweeping action, and through a complete circle if desired, while the handle can also be shifted to turn or tilt the lamp in a vertical or other plane, to change the plane in which the lamp turns with the handle when turned. Thus, for example, the lampcan be turned about a vertical ornearly vertical I inspection light about the boat or vehicle.

The invention also aims to provide a' searchlight and control of the character -specified which will be simple and inexpen- Specification oi Letters Patent.

With the foregoing and other objects in view, which will 'beapparent as the invention is better understood, the invention resides in the construction and arrangement of parts as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated inthe accompanying drawings, Wherein Y Figure l is a side elevation of the Search light and control, a portion being broken away. A

Application filed July 1, 1918. Serial No. 242,832.

Fig. 2 is a side elevation showing the searchlight as used as a hand lamp for 10- cating trouble or making inspection.

, Fig. 3-is a perspective view of the stand with the lamp removed.

Fig. 4a is a side elevation of the handle. The mounting for the searchlight embodies a suitable stand or support 1 having a base 2 to be fastened in any preferred manner on the roof 3 of a boat cabin'or to any other supporting member. The lamp 4 (an electric lamp being preferably used) is mounted on the stand 1 for turning movement in two different planes at right angles with one another, and although the lamp is I shown as being capable of horizontal and vertical turning movements, it can be readily arranged'to turn in other planes as circumstances may dictate. In order to so mount the lamp 4, the upper end of the stand 1 has a fork 5, and a'lamp supporting arm 6 has a bearing 7 at one end pivoted within the fork 5 on a horizontal pivot 8 to swing upwardly and downwardly in a vertical plane,f

split and provided with a clamping screw 10.

. in-g stem 11 provided with a, depen ingshank 12 journaled for rotation throu h the bearing 9. The shank 12 has a shoul er 13 seatable above the bearing 9 to support said and the pivot 8 can also be a screw to clamp shank, and said shank being loose within the bearing 9 permits the lamp 4 to turn about the vertical or substantially vertical axis of the shank 12 in a horizontal plane, so as'to directthe light in, various directions around the stand 1, and when the arm 6 is swung upwardly and downwardly onthe pivot 8 the lamp is tilted vertically, for either raising or lowering the beam. of light as desired and to determinethe plane in which the lamp 4 will turn with the shank 12. The electrical cord 14 containing the conductorsforthe lamp 4 dangles from the end of the stem 11, so as not to impede the movement of the lamp. By' tightening the screw 10, the shank 12 will be clamped in the bear.- ing 9 to prevent turning movement thereof,

the bearing 7 in the fork 5 when turning movements of the shank 12 and arm 6 are,

not wanted. A cotter pin 15 or other retainingelement is inserted through the shank' 12 underneath the bearing 9 tohold said shank in lace.

tive, and includes a rod 16, disposed vertically as shown, in substantial alinement wlth the shank v12 below the. same and sliding loosely through an aperture or opening 17 in the base 2 of the stand 1. The rod 16 also extends through an opening provided in theroof or support 3 and is provided at'its I lower end or that end remote fromthe lamp with a suitable handle 18 for turning and sliding said rod, which has its upper end connected by a universal joint with the lower end of the shank 12. This joint includes a coupling 19 pivoted, as at 20, to the upper end of the rod 16, and by means of a cotter pin or removable pivot 21 to the shank 12 at right angles with the pivot 20. 7 Such joint enables the shank 12 and rod 16 to assume different angles relatively to one another and still rotate as a unit.

In operation, it will be noted that the handle 18 by being grasped by the hand and turned with the rod 16 will turn the shank 12 and lamp 4 carried thereby, so as to turn the light to different directions around the stand 1, and through a complete circle. By pushing upwardlyor pulling downwardly on the handle, so as to shift or slide the rod 16 longitudinally,fthis will either raise or lower the shank 12 and-arm 6. In this way,

the lamp can be tilted or turned upwardly and doWnwardly,-and the universal joint or flexible connection between the shank 12*ofv the lamp mounting and operating rod 16 enables said rod to readily turn the shank 12 at various angles thereof. The two motions of the handle. 18 can be accomplished either individually or jointly, whereby the operator has full control of the position of the lamp. The handle member serves as an extension for the lamp shank to permit con- ,swinging the mounting.

The control 1s .verysimple yet very efl'ec trolthereof easily and in a simple manner and the handle member forms a, unit with the shank to move as a part or extension thereofinsteadfof through the medium of levers, links and the like.

To use the lamp as a hand lamp, trouble 7 light or inspection light, it is only necessary to remove the cotterpins 15 and 21, which permits the shank 12.to be lifted from the bearing 9 with the lamp 4, as seen in Fig. 2.
