United States Patent O MECHANICS LIGHT SUPPORT Richard D. Barton, Wilkinson, Ind.

Application May 10, 1957, Serial No. 658,313

1 Claim. (Cl. 240-88) The present invention relates to new and useful improvements in supports particularly for mechanics trouble lights of the type including an electric lamp on one end of a conductor cord and has for its primary object to provide, in a manner as hereinafter set forth, novel means for adjustably suspending such lights for rotary and universal swinging movement from a ceiling or other suitable elevated support.

Another important object of the invention is to provide a support of the aforementioned character which is counterweighted for automatically elevating the mechanics trouble light to an out-of-the-way position when it is not in use.

Still another important object of the invention is to provide novel means for adjustably and detachably hanging the mechancs light from the support.

Other objects of the invention are to provide a support of the character described which will be comparatively simple in construction, strong, durable, compact, of light weight and which may be manufactured and installed at low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference bein-g had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a view in side elevation, illustrating a support embodying the present invention in use, showing the counterweight broken away in section;

Figure 2 is a view in horizontal section through one end portion of the device, taken substantially on the line 2 2 of Figure l;

Figure 3 is a view in transverse section, taken substantially on the line 3-3 of Figure 1; and

Figure 4 is a view in transverse section, taken substantially on the line 4 4 of Figure 1.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a tubular boom 5 of suitable material and dimensions. The boom 5 is suspended off center for rotary and substantially universal swinging movement from a ceiling 6, for instance, through the medium of a hanger 7 comprising a swivel 8.

Mounted for longitudinal sliding adjustment in the forward end portion of the tubular boom 5 is a resilient, tubular extension 9 of rubber or other suitable material. Adjacent its free end, the tubular resilient extension 9 has formed in its upper portion an opening 10. The opening 10 is for the passage of the conductor cord 11 of a mechanics light which is designated generally by reference character 12, said light including an electric lamp 13, etc., on one end of the cord 11. A clamp 14 compresses the forward end portion of the resilient tubular extension 9 around the cord 11 (see Fig. 2) for frictionally clamping said cord in adjusted position in said extension. Bands ICC 15 secure the cord 11 to the boom 5 at longitudinally spaced points. Of course, the cord 11 is provided en its other end with a suitable plug (not shown) for insertion in an electric receptacle in the usual manner.

Mounted on the rear or other end portion of the boom 5 is a counterweight 16. The counterweight 16 includes a cylindrical container 17 of suitable material which is lled to the desired level through an opening 18 in its upper portion with sand, as indicated at 19.

The rear end portion of the tubular boom 5 extends lon-` ygitudinally into the upper portion of the container 17 through a circular opening 20 provided therefor in the forward end 21 of said container. Bolts 22 are mounted vertically in the rear end portion of the boom 5 at longitudinally spaced points and rise from said boom. The bolts 22 pass through apertures provided therefor in the upper portion of the container 17 and have threaded thereon wing nuts 23 for securing the container 17 in position.

It is thought that the use of the support will be readily apparent from a consideration of the foregoing. Briey, the cord 11 of the mechanics trouble light 12 is threaded through the forward end portion of the tubular extension 9 and the opening 10 and secured at 15 on the boom 5. The clamp 14 is then applied to the free end portion of the tubular extension 9 for frictionally securing the cord 11 in adjusted position. The weight or counterbalance 16 is filled to the desired level with the sand 19 for counterbalancing the mechanics light 12. The hanger 7, comprising the swivel 8 permits the boom 5, with the mechanics light 12 suspended therefrom, to be readily turned or rotated and swung in substantially any direction. When the mechanics light 12 is not in use the counterweight 16 is permitted to actuate the boom 5 for elevating said mechanics light to an out-of-the-way position in an obvious manner. rIf desired, the boom 5 may be adjusted longitudinally on the hanger 7.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

A support of the character described comprising: a tubular boom, a hanger connected off-center to the boom for suspending same for swinging movement from an elevated support, a resilient tubular extension removably mounted for longitudinal sliding adjustment in one end portion of the tubular boom and projecting longitudinally therefrom, said extension having an opening therein at an intermediate point, a conductor cord mounted for sliding adjustment in the forward end portion of the extension and emerging therefrom through the opening and the free end thereof, an electric lamp on one end of the cord, a clamp contracting the free end portion of the extension for frictionally securing the cord in adjusted position, and a counterweight on the other end portion of the boom.
