TROUBLE LIGHT Filed July 12, 1941 2 Sheets-Sheet 1 Inventor jesierBernaraf 6 1'6 L. CURTIS 2,299,683 Q TROUBLE LIGHT Filed July 12, 1941 2 Sheets-Sheet 2 Him Patented Oct. 20, 1942 UNITED STATES PATENT OFFICE TROUBLE LIGHT Lester Curtis, Ness City, Kans.

Application July 12, 1941, Serial No. 402,213

2 Claims.

This invention relates to shop or trouble lights, generally used in automotive and analogous machine shops to provid proper illumination, more or less concentrated, on the work; and an object of the present invention is to provide a light of this character which may be readily moved from plac to place; will not readily tip over, and can be readily adjusted and manipulated to give the desired illumination.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure l is a side elevational view of a light embodying the features of the present invention.

Figure 2 is an enlarged detail elevational view of the upper portion of the standard of the light, and associated parts, with certain parts broken away and shown in section.

Figure 3 is a fragmentary detail view partly in section and partly in elevation illustrating certain details hereinafter more fully referred to.

Figure 4 is an elevational view of a sleeve and associated parts hereinafter more fully referred to.

Figure 5 is a fragmentary longitudinal sectional view through two of the telescoping sections of the standard showing the manner of securing the sections in adjusted position.

Referring more in detail to the drawings it will be seen that in accordance with the present invention there is provided a suitably shaped base 5 from which rises a short post 6 that embodies opposed spaced parallel portions between which is pivoted, as at I, a disk-like head 8 provided on the lower end of an extensible standard, indicated generally by the reference numeral ID.

The standard I is composed of a plurality of telescoping sections II, I2 and I3 and the head 8 is formed integral with the section I I as shown.

The standard In is secured at the desired position of angular adjustment relative to the vertical through the medium of a screw I4 that threads through the post IE to bind against one side of the head 8.

Outward movement of the sections of the standard In relative to one another is limited by providing each of the standard sections I 2 and I3 at their respective inner ends with springpressed detent balls I5 that are urged outwardly through openings I6 through the medium of an interposed spring I1; and recesses I 8 provided internally of the sections and into which the balls spring as one section is moved outwardly towards the extremity of the free end of the telescoping section as will be clear from a study of Figure 5.

Also the sections are secured in extended position relative to one another, and at-the desired adjustment, through the medium of screws I9 threaded through openings provided on the telescoping sections II and I2 and adapted to bind against the telescoped sections. Thus it will be seen that the section I2 is secured at the desired adjustment relative to the section II by threading the screw I9 associated with the section II into binding engagement with the section I2, and the section I3 is secured at the desired position of adjustment relative to the section I2 by threading the screw I9 associated with the section I2 into binding engagement with the section I3.

At its free end, the section I3 is provided with an integral yoke 20 between which is pivoted a disk 2| as at 22.

Th disk 2| is secured at the desired position of rotative adjustment through the medium of a thumb-screw 23 that threads through one leg of the yoke 20 into binding engagement with the disk 2| as illustrated to advantage in Figure 3.

Secured on the periphery of the disk 2I and extending substantially tangential to th disk is a sleeve 24.

The sleeve 24 has extending from one side thereof a tubular shank 25 that is fitted in a radial socket 26 provided in the disk 2I as shown to advantage in Figure 2.

A rod 21 has a working fit through the sleeve 24 and is frictionally held in adjusted position longitudinally with respect to the sleeve 24 through the medium of a ball detent 28 that is housed within the shank 25 and is normally urged into frictional contact with the rod 21 through the medium of a coil spring 29 as also shown to advantage in Figure 2.

The rod 2! is positively secured at th desired position of adjustment relative to the sleeve 24 through the medium of a thumb-screw 3|], as also best shown in Figure 2.

At one end thereof, the rod 21 is equipped with a conventional switch-equipped lamp socket 3| to accommodate an electric lamp bulb (not shown) and a reflector 32.

A- conventional lamp cord 33, connected with the socket 3|, extends through the rod 21 and at its free end is suitably equipped with a plug for connection with a suitable electrical receptacle for placing the lamp in an electrical circuit.

It will be apparent that the rod 21 can be shifted longitudinally through the sleeve 24 to extend the rod 2! laterally relative to the standard l0, and the disk 2| and associated parts rotated to place the rod 27 at the desired position of angular adjustment relative to the standard {0; while the standard m, as before mentioned, may be rotated and secured to any desired position of angular adjustment relative to the perpendicular. Thus it will be seen that the lamp has a wide range of adjustability.

In actual practice, it is intended that the parts of the lamp be of metal, but light enough in weight so as to render the lamp portable.

It is also apparent that the adjustment, as desired, may be quickly and readily made thus enhancing the value of the lamp for the purpose intended, namely as a trouble lamp in automotive and similar shops.

While I have herein illustrated. and described what is considered the preferred embodiment of the invention, I do not wish to limit myself to the precise details of construction, combination and arrangement of parts as herein illustrated 1. In a lamp stand of the character described, a standard, a disk rotatably mounted on the upper end of the standard, means on the standard and engaging the disk for securing the latter at the desired position of rotative adjustment, said disk having a radial socket in its periphery, a sleeve having a lateral extension positioned in the socket, said sleeve having its axis disposed substantially tangential to the disk, a rod having a sliding fit through said sleeve, and means on the sleeve and engaging said rod to secure the latter at the desired position of adjustment longitudinally relative to said sleeve.

2. A lamp stand comprising a standard having a bifurcated upper end, a disk rotatably mounted thereon, means carried by said bifurcated end engaging the disk to secure the latter in rotatably adjusted position, said disk having a radial socket in one edge, a sleeve having a tubular extension communicating with the interior of the sleeve, said extension being positioned in the socket, a rod slidably mounted in the sleeve, and friction means in the extension engaging the rod to secure the latter in adjusted position in the sleeve.
