MEGHANIGALLY OPERATED SEARCH LIGHT.

APPLICATION FILED SEPT. 12, 1911.

Patented May 28, 1912.

MYRON L. SEVERSON, OF PASSAISJ, NEW JERSEY, ASSIQNOR F ONE-HALF TO WILLIAM S. SPIEGELBERG, OF PASSAIQ, ,NEW JERSEY.

To all whom, it may concern Be it known that I, MraoN L. Snvnnsox, a citizen of the United States, residing at Passaic, in the county of Passaijc and State of New Jersey, have invented new and useful Improvements in Mechanically-Operated Search-Lights, of which the following is a specification. p

The purpose of this invention is the provision'of a search light which may be operated at a distant point to enable the rays of light to be directed to any angle above or below the horizon or to any desired angle approximately in the plane of the horizon, so that the rays of light may be directed upon any object or point in substantially the same manner as a manually operated search light, the invention providing means for controlling the various movements of the light from a convenient point. i

i In its specific application the invention-is designed'to provide a search light for use upon board of ships or other water craft, so

that the light may be operated from the 3 pilot house and the rays directed in any direction.

The invention enables the lamp to be located forward of thevessel well in advance of. the pilot house and enables the' rays of light to be thrown in the desired direction, which of especial advantage in inclement weather and under conditions requiringthe pilot tobot h control the movements of the vessel and at the same time illuminate the pointor object to be clearly discerned.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawing, and pointed out in the appended claims.

Referring to the drawing, forming a part of the specification, Figure 1 is a side view of a search light and operating mechanism therefor embodying the invention. Fig. 2 is a sectional detail, showing the parts on a larger scale.

Corresponding and like parts are referred to in the following description, and indicated in both views of the drawing, by the same reference characters.

The numeral 1 designates the deck of a vessel or other support upon whlch the lamp is mounted. A stand 2 is secured to the support 1 and {is provided with a vertical open- Specification of Letters Patent.

ing in which is mounted a sleeve 3, the latter havingai cap 4: at its upper end which overlaps the stand to support the sleeve therein. A bevel gear 5 is secured to the lower end of the sleeve and is in mesh with a companion vbevel gear 6 secured to one end of a. horizontal tube 7, which is provided at its opposite end with a hand wheel 8; A fork 9 is secured to the cap 4: so as to turn with the sleeve 3. A lamp 10 of any variety or make is mounted between the fork members of the bracket 01' support 9 so as to turn freely about a horizontal axis. The tube 7 may be of any length or construction and serves as meansfor transmitting motion from the hand wheel 8 to the gearing and 6 for turning the sleeve 3 in the stand 2. 'It' is to be understood that the lamp may be located in any desired position and that the hand wheel or like part 8 is arranged within convenient reach of-the operator to be actuated when it is desired to move the lamp.

A rod 11 gasses througli the sleeve 3 and is movable therein. A link 12 is pivotally connected at its upper end with the lamp 1O andhas a ball and socket joint connection with the rod 11 so as not to interfere withthe angular movements of the lamp about a vertical axis. The lower end of the rod 11 has a slot.l3 through which the horizontal member 1st of a bell crank pivoted at 15 passes. A rod 16 passes through the tube 7 and a link 17 connects one end of the rod with the vertical member 18 of the before mentioned bell crank. The rod 16 PI'OJGCtS beyond the tube 7 and is provided with a.

hand wheel 19. A longitudinal movement of the rod 16 within the tube 7 causes a pivotal movement of the bell crank and a vertical movenientof the rod 11, with the result that the lamp '10 is turned about a horizontal-axis so as to throw the rays of light upwardly or dowi'iwardly may be required. For convenience of moving-the rod 16 and holding the same in the adjusted position it is preferred to provide a screwthread connection between the said rod and the tube 7. This construction necessitates the provision of a universal joint in the rod 16 and by preference said rod is connected to the link 17 by means of aball and socket joint.

The parts being assembled substant-iall in the manner indicated rotary movement of the tube 7 effects a corresponding rotation .(i C E.

angle the hand wheel 8 is turned to move the lamp about a vertical axis to throw the light to the required angle with reference to the horizontal.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction'and of the method of operation will be readily ap parent 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 changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention what is claimed as new-,vis:'

1. In search light operating means, the

combination of a lamp support mounted to turn about a vertical axis, a lamp mounted upon said support to turn therewith-and adapted to turn about a horizontal axis, a member mounted centrally within the lamp support and having connection with the lamp, a tube having an approximately horizontal arrangement, gearing between the tube and lamp support to admit of turning the.

latter to cause the rays of light from the lamp'to sweep the horizon, a rod mounted within the tube and having screwthread connection therewith, and connecting means between said rod and the member mounted axially within the lamp support to move the lamp to elevateor lower the rays of ligh emanating therefrom. I i

2. Search light operatlng means comprisinga stand, a sleeve mounted vertically withinthe stand, a lampsupport mounted upon the sleeve, a lamp plvotally connected with the lamp support to turn about a horizontal axis, a tube having arr-approximately horizontal arrangement, gearing between said tube and the said vertical sleeve, a rod mounted in the vertical sleeve and having connection with the lamp to move the same about its horizontal axis, a second rod mounted in the tube and having screw-,

thread connection therewith, and connecting means between the horizontal and vertical rods.

3. Search light operating means comprising a stand, a sleeve mounted vertically in the stand and having a cap at its upper end, a bevel gear secured to the lower end of the sleeve, a tube having an approximately horizontal arrangement, a bevel gear secured t the tube and in mesh with the bevel gez: connected with the sleeve, means for impar ing rotary movement to the tube, fil -13.11. support mounted upon the sleeve, a lamp mountedupon the lamp support to turn about a horizontal axis, a rod mounted ecu-1.

trally within the said sleeve, a link connecting the upper end of said rod with the lamp, a bell crank mounted beneath the stand and having its horizontal member connected to the lower end of the rod mounted in the sleeve, second rod mounted within the before mentioned tube and having screw thread connection therewith, and a link connecting the vertical member of the bell (rank with the rod threaded into .the tube.

In testimony whereof I affix my signature m presence of two witnesses.
