MYRON L. SEVERSON, OF PASSAIG, NEW JERSEY, ASSIGNOR OF ONE-HALF TO WILLIAM S. SPEIGELBERG,

OF PASSAIC, NEW JERSEY.

SEARCH-LIGHT.

To all whom 'it may concern:

Be it known that I, MYRON L. Snvmzson, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented new and useful Improvements in Search-Lights, of which the following is a specification.

This invention is designed primarily to provide a search light which may be operated from a distant point and yet admit of the beam of light being thrown to any elevationor to any angle so as to illuminate any desired point.

The invention provides a mechanism utilizing fluid as the power transmitting means in the adjustment of the light both with reference to altitude and horizontal angular ad ustment.

'lhe invention provides a search light which may be mounted upon the mast of a or'located in any convenient position an adapted to be operated from a distant oint without exposing the manipulator, the invention bein of special advanta e in locatin the lig t upon the mast oi a ship or ot er elevated point.

The invention consists of the novel features, details of construction and combination of arts, which hereir fter will be more particu arly set forth, illustrated in the accompanyin drawings, and pointed out in the a pen ed claims.

Re erring to the drawings, forming a partof the specification, Figure 1 is a view in elevation of a search light and operating means embodying the invention. Fig. 2 is a vertical section of the lamp su port and the controlling means admitting o directing the beam of light in the desired direction. Fig. 3 is a horizontal section on the line H of Fig. 2. Fig. 4 is a horizontal section on the line 3 of Fig. 2, lookin upward, as indicated hy the arrows. lg. 5

is an enlarged section of the'cylinder and means whereby the lamp is turned about a vertical axisl Corresponding and'like parts are referred to in the following descrl tion, and indicated in all the views oft e drawings, by the same reference characters.

(The lamp support 1 consists of a stand of suitable construction, the same having a vertical 0 ening 2 and bores 3 and 4 forming cylin ers in which pistons 5 and 6. are arranged to operate. The lamp 7 for propecificatlon of Letters Patent.

jecting the search light may he of any construction and is mounted upon an upri ht 8 so as to'turnabout a vertical and a lint-i zontal axis to admit of throwing the beam of light in the required direction both horizontally and vertically. A sleeve 9 is mounted in the opening 2 and has a flange 10 at its upper end to extend over the stand 1 and support the sleeve within the opening 2. The upright 8 is mounted upon the flange 10 of the sleeve 9. The pivotalconnection 11 of the upright 8 with the lamp 7 is to one side of the vertical axis about which the lamp turns. The upper end of the part 8 is forked, the fork members being pivotally connected to opposite sides of the lamp 7. A pinion 12 is secured to the lower end of the sleeve 9 and meshes with a toothed segment 13 secured to the lower end of a stem 14 which extends into the cylinder 4. When the lamp is arranged to oint straight ahead or inline with the travel of a vessel the middle portion of the segment 13 is in mesh with the pinion 12 so that upon turning the stem 14 either to the right or to-the left the lamp is caused to make a corresponding revolution. Suitable stops 15 are had to limit the movements of the toothed segment 13 in each direction. The piston 6 is revented from turning in the cylinder 4, t is being accomplished .by means of a stud 16 on the piston entering a vertical groove 17 formed in the wall of the cylinder 4. The piston 6 has a hollow stem 18 which receives the stem 14. -A spiral slot formed in the hollow stem 18 re- 'ceives a stud 20 projecting from the stem 14, hence movement of the piston 6 in the cylinder 4 causes rotation of the stem 14 and a like movement of the toot-lied segment 13 and the latter meshing with the pinion 12 turns the sleeve 9 and the lamp 7 so as to project the beam of light in the desired direction. .A passage 21 is formed in the stand 1 and communicates with the upper end of the cylinder 4. A pipe 22 connects with the passage 21 and with a suitable source of supply of compressed air or ot-her fluid motive medium. A two-way cock 23 is located in the length of the pipe 22 at a convenient point and by manipulatin said valve a fluid medium may be admitte into .the cylinder 4 or exhausted therefrom. When the two-way cock 23 is turned to out inder 4 and to open the outlet the piston 6 is moved upwardly in the cylinder by means of an expansible helical spring 24.

A rod 25 is mounted in the sleeve 9 and extends therethrough. A link 26 connects the upper end of the rod 25 with the lam 7. Ball and socket joint connections are liad between the link 26 and the lamp and the rod 25 to admit of angular adjustment of the lamp as well as vertical adjustment thereof. The lower portionof the rod 25 extends laterally, as indicated at 27, thence vertically, as shown at '28, and connects with the piston 5. A spring 29 of the expansible helical type is located in the cylinder 3 and normally exerts an upward pressure upon. the piston 5. A passage 30 is formed in the stand 1 and communicates at its upper end with the cylinder 3. A pipe 31 connects with the passage 30 and leads to a suitable source of supply of compressed air or other fluid medium. A two-way cock 32 is located in the length of the pipe 31. Upon turning the cock 3?. to supply compressed air or other fluid medium to the upper end of the cylinder 3 the piston 5 is depressed, thereby moving the rod 25 downwardly and throwing the beam of light upwardly. Upon moving the cock 32 to a position to relieve the upper end of the cylinder 3 of pressure the spring 29 forces the piston 5 upwardly, thereby elevating the rear end of the lamp an throwing the beam of ii ht downwar ly. By proper adjustment 0 the controlling means 23 and 32 the lamp 7 may be moved so as to throw the beams of light to any altitude and horizontal angular adjustment as may be required.

From the fore oing description, taken in connection with t e accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such chan s may be made when desired as are within the scope of the claims appended hereto.
