ROY E. SAGLE, OF ROSEVILLE, OHIO.

SPOT-LIGHT.

Application led December 27, 1919.

To all fen/"10m z'z may concern.'

Be it known that I, Roy E. SAGLE, a citizen of the United States, residing at Boseville, in the county of Muskingum and State of Ohio, have invented certain new and useful Improvements in Spot-Lights, of which the following is a specification.

This invention relates to an improvement in spot lights more particularly for use on motor vehicles, and constructed with a view ling the beam direction, and to providing a mounting for the spot light so that complete regulation and control .thereof may be had without the necessity of reaching beyondl the side of the car for such purpose.

The improved spot light is supported in a bracket made up of independent tubular sections, cables arranged to pass through such tubular sections being provided for adn justing the light, such tubular sections also housing the electric conductor. jacent ends of alined sections through which the cables pass, have threaded connection in a bearing sleeve, whereby the sections may be adjusted as a proper tension on the cables may require. The bearing sleeve is rotatively mounted in a bracketsecured to the car, so that the operating end of the structure may project within the car, to thereby permit Jfull control by the driver without the necessity of reaching beyond the protected area of the car Jfor such purpose.

In the drawing:

Figure 1 is a view in vertical section illustrative ol the invention.

Fig. 2 is a plan of the same.

The present invention is directed more particularly to what may be termed the arm member of the spot light, and which, as shown is made up of a hollow yoke 1 and tubular sections 2 and 3 projecting therefrom. The section 2 is secured to the yoke, and said sections 2 and 3 are arranged in alinement and their proximate ends are threaded at 4 into a bearing sleeve 5. The lamp casing or bowl 6 is mounted for the usual swinging movement between the ends of the yoke, and aside from the following particulars may be of any desired form or structure. The bowl 6 is held in the yoke at diametrically opposite points, one such connection. comprising a tubular extension 7 on the bowl, to rotatively engage a correspondingly shaped lateralprojection 9 of one yoke end. The opposite mounting ot Specification of Letters Patent.

the bowl involves a cylindrical enlargement .10 of the yoke end, opening toward the bowl, in which enlargement is arranged a pulley memberv 11 liXed to the bowl by a bolt 12, which has a rotative mounting in the outer wall of the enlargement and is held within the bowl by a nut 13. The bowl is thus rotatlvely mounted within the yoke, and is provided with a relatively fined pulley completely housed within the hollow yoke.

The free or inner end of the section 3 is circumterentially enlarged to provide `a casing 14 the side opening of which isclosed by a removable plate 15. A shaft 16 is mounted transverse the casingrlt, and provided within the casing with a pulley 17, and beyond the casing with a hand wheel 18.

Operating cables 19 and 2O connect the respective pulleys 11 and y17 and between the pulleys are housed in the tubular formation of the parts. These cables are mounted so as to bear approximately centrally of the respective pulley, and are oppositely 'Yoonnected to said pulleys. Forfexample cable 19 passes centrally over pulley 17, with its end deflected from the center line of thev pulley and connected to one side of such line on the lower side of said pulley. The

cured on the upper side of the pulley.

Cable 20 is similarly though reversely connected to the respective pulleys, the operating parts of the cable 2O passing over the center line of the pulley.

With this arrangement it is apparent that by manipulation of the hand wheel 18 the spot light may be moved as desired in its pivotal mounting in the yoke, each pulley taking up the slack of the nonactive cable. Furthermore by the obvious rotation of the bearing sleeve 5 the sections 2 and 3 may be spaced as required to properly tension the cables and thereby maintain the adjusting means eilicient, notwithstanding the stretch ot the cables following continuous use.

The energizing conductor 21 tor the lamp socket lpasses through the mounting 7, through the hollow yoke and through a protected tube 22 secured to and resting within the section 3 and extending into but not secured to the section 2. The conductor passes through a nipple 23 to the battery, and from the battery a conductor 24 extends through the nipple 23 into the tube 22 and to an insulated contact point 25 in the wall of the housing 14. A switch plate 26 is adapted to be engaged with the contact point 25 at will, to thereby close the light circuit, the other side of the circuit being grounded through the structure.

The spot light as a whole is mounted in a bracket 27 to be removably secured to the automobile as the wind-shield post, or other appropriate part. The receiving end of this bracket comprises

separable sections

28, 29 adapted to be clamped about the bearing sleeve 5 with suicient friction to support the structure without interfering with rotative movement of such sleeve and spot light structure. This mounting provides for the adjustment of a spot light in the direction at right angles to that permitted by the yoke mounting, thus providing the necessary universal adjustment.

The receiving end of the bracket end 27 is mounted at right angles to the length of the car, and such bracket may if desired be fixed in this position` The free end of the spot light structure is thus arranged wholly within the car, and all adjustments of the like, as well as the energization and denergization thereof may be carried out by the driver without the necessity of reaching beyond the car. This is a desirable feature particularly in closed cars, or where there is a necessity for the use of protected curtains in open cars. By this mounting the driver has perfect control of the spot light without the necessity of opening a window or loosening the curtains.

What I claim is:

1 A spot light including a hollow yoke having a threaded extension, a lamp bowl pivotally supported between the ends of the yoke, a tubular section threaded at one end and formed at its opposite end with a circumferentially enlarged casing, a threaded bearing sleeve flanged at opposite ends, the threaded extension of the yoke and the threaded end of the tubular section engaging the threaded nut, a bearing supporting the nut between the fianges, a pulley mounted in the housing, a pulley mounted to rotate with the lamp bowl, and a cable passing around the pulleys to turn the lamp bowl.

2. A spot light having a hollow yoke provided with a threaded extension, a lamp bowl pivotallymounted in the yoke, a tubu` lar section in alinement with the extension and threaded at one end, a tube secured within the tubular section and extending into the tubular extension, a threaded bearing nut engaging the threaded ends of the extension and the tubular member, the opposite ends of the bearing nut having flanges, a support engaging said nut between tlie flanges, and means carried by the tubular member and extending through same and the yoke to the lamp for turning the latter.

In testimony whereof I aiiix my signature.
