ELECTRIC SEARCH-LIGHT.

SPECIFICATION forming part of Letters Patent No. 513,052, dated January 16, 1894.

Application iiled August 22, 1893. Serial No. 483,756. (No model.)

T0 all whom it may concern.:

Be it known that I, CHARLES EDWARD ONG LEY, a citizen of the United States, residing at New York city, in the county and State of New York, have invented a certain new and useful Improvement in Search-Lights, of which the following is a specication.

My invention relates to improvements in Search lights and particularly a means for exposing and concealing the light, in a way to make a ash light for signaling purposes, together with means for holding and adjusting the lamp to throw the light in any desired direction. The same is illustrated in the accompanying drawings, in which like letters refer to like parts.

Figure lis mainly a vertical section of the lamp, taken through the center of the base. Fig. 2 1s a side perspective View of the lamp, wlth portions broken away in section. Fig. 3 is a horizontal section of the carbon point and screen or sleeve. Y

The' base A is cored through the center and provlded preferably with ball or'other antifrlction bearing a2 a2. B is a bracket having a base b', arranged to be seated on the base A and provided with like bearings b2 and b2. The shaft bs is fixed to the base b and passes freely through the core of the base A. It is provided with the hand wheel b4. The shaft h3 1s also cored through the center to receive the sleeve and rod b5. The rod is provided with the crank arm 57 and the sleeve is internally threaded to receive the screw be, which 1s provided with the friction wheel bs. Extending out of the bracket base b are the forked arms b and b9, having journal bearlngs at the ends thereof blo and bw; these arms are preferably made hollow to carry the electr1c wires to the lamp, and are bent out ofthe. vertical plane as illustrated in Fig. 2.

O is the rellector, and D an arc lamp.

1 prefer to construct the reflector with the cyhndrical hood lined with a non-reiiecting surface c4, a reilecting surface 'c' being placed atone end thereof, and I prefer to construct th1s reliecting surface of glass, of concave form, hollow and filled with water or other liquid. Secured to the outside of the cylinder C are the single shafts c2, c2 which are journaled in the bearings b1 and 61, and on the under side of the same are secured the ways cs in which travel the friction wheel bs. The are lamp is secured within the cylindrical hood on the base d orin any convenientmanner, and is suitably connected with an electric circuit, preferably through the hollow arms b9 and b9.

While I have shown an arc lamp, as the light employed, I do not intend to limit myself to that form of light, but I may use any light with which my device may be employed.

E is a screen in the form of a sleeve of a size to receive the carbons of the arc lamp, and to move freely about them, it is pivoted to an arm e as shown in horizontal section in Fig. 3, said arm being pivoted to the interior of the cylinder at e2. The armature lever e3 is pivoted to the upright stay e4 and provided with the armature e5 at one end, andthe other end isadjustably connected with the arm c by the rod e". The electromagnete7 is in an electric circuit controlled by a key. I have shown the same in a shunt from the main light circuit controlled by the key es. I disclose this electrical means of operating the screen or sleeve E and I prefer to operate the same in this way, but it may be controlled mechanically by using the armature lever as a key or otherwise. I have also shown the screen in the form of a sleeve, which is aconvenient form to use with the arc lamp, but may use other forms and do not limit myself to a sleeve.

The operation of my device is as follows: The making and breaking of the electric circuit by the key es causes the screen or sleeve E to conceal or expose the light as the same may be required, enabling the operator to signal by flashes of light.

In the construction shown, the lamp is arranged to be secured to the roof of the pilot house of a vessel by the bolts a-a or otherwise, with the hand wheel b4 and crank arm hl passing through said roof and within reach of the pilot on the under side of said roof. A horizontal movement of the lamp is obtained by turning the hand wheel b4, which causes the bracket B to revolve on its bearings. A vertical movement is obtained by turning the crank arm bi, which operates the screw arm b and causes the friction wheel b8 to run in the Ways c3 as the reflector is raised or lowered, the bearingvbeing at aneccentricto tlie point at which the reflector is pivoted to the bracket arms.

What I claim is- 1. The combination of means forsupporting and adjusting'a Search light, consistingI of a base upon which is seated and pivoted to move horizontally a bracket having two arms between which is pivoted to move vertically a reiiector the horizontal movement" being controlled by a shaft passing through said base, and the vertical movement by a bar passing through said shaft and bearing on the rellector at an eccentric to its pivotal point, substantially as described. l

`2.` Ina Search light,lthe combination of a light, ascre'en an'd means for reciprocating said screen to inclosel or expose the light, a reflector containing the light, and means to support and; adjust said reflector consisting of a basef upon which is" seated a bracket pivoted to move horizontally and having two arms between which is pivotedthe reeetor to move vertical`ly,a= shaft secured tothebracket l and passing through the base anda bar, pass'- ingithrough' said shattand bearing on the reflector atan eccentric` to its pivotal poi-nt, substantially as=describedL 3. Ina search light, the combination ot` a light, a screen and means for reciprocating said screen toy inclose or expose the light coirl sistingi of an electroy magnet in circui-t and means to control said circuit, and an armasarms between which is pivoted the rellector "to move vertically, a shaft secured to the bracket and' passing through the base and a bar passing through said shaft and bearing on thereector at an eccentric to its pivotal point, substantially as described.

4. In a search light, the combination of a light, a screen and means for reciprocating `said screen to inclose or expose the light, consisting of an electro magnet in circuit and means to control said circuit, and an armature for the magnet connectedwith thescreen by the: levers'. and adjustable arm;y arellector containing the light',l andfme'ansf to support and.' adjust; saidreflector consisting. oli a base upon which is seated a bracket pi'votedV to move horizontally andfhaiving twovarms between which is pivoted thorellectorto move vertically, a shaft secured to'therbracketand passing through the'base andf a b'a-r passing through said shaft and bearing orr the. retlector at an eccentric-to its pivotal point, substantiall'y as described.
