WALL-SUPPORT FOR BRACKET-LAMPS.

Application flied January 11, 1913. Serial No. 741,539.

To all 'wlmmif mag) concern:

lie it known that I, 'lnnononn Inmnmsn,

a citizen of the United States, residing at .p

Vans Il arbor. in the county of Delta and State of Michigan, have invented new and useful Improvements in \Vall-Supports for Bracket-Lamps, of which the following is a specification.

This invention relates to an improved wall support for bracket lamps, and it has for its object to produce a support of simple and etlicient construction, including a sliding member, whereby the lamp is free to be supported vertically for convenience in adjusting the light to the position where it may be 'best utilized.

Another object of the invention is to produce a supporting device, including a rack bar composed of a plurality of units, which, when joined together, will form a supporting member of considerable or of any desired length, and which, when disassembled, may be stored or packed in small compass. With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications, within the scope of the appended claim, may be resorted to, when desired. In the drawings: Figure 1 is a perspective view showing a bracket lamp mounted on the improved support. Fig. 2 is a vertical sectional view taken through the lamp supporting slide and through proximate ends of two units of the guide. Fig. 3 is a perspective view, showing the ends of two guide units disassembled.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved supporting device comprises a rack bar which, for convenience, is made of a plurality of units, a top 1, a bottom unit 2, and one or more intermediate units 3, of which one has been shown, although such intermediate units may be disensed with. 4

Each unit of the rack bar is provided with ratchet teeth 4, and with laterally extending flanges 5. The-several units are also provided at their proximate ends with interengaging lugs (i and recesses 7, as clearly shown in Fig. 3. Each .unit is provided with one or more countersunk apertures 8 for the passage of fasteningmembcrs, such as screws 9. It will be seen that by using any desired number of the intermediate units 3, a supporting member or ratchet bar of any desired length may be produced. A slide 10 is provided, said slide being fitted on the' ratchet bar composed of the several units, and being suitably constructed to engage the flanges 5 on the ratchet bar. The slide is provided at its lower end with lugs 11, between which a dog 12 is pivoted on a pin 13, said dog being provided with a finger piece 14 which also serves as a weight, whereby the dog is maintained gravitationally in engagement with the teeth -or ratchets of the supporting bar. The slide 10 is also provided with forwardly extending lugs 15 having vertical apertures 16 for the passage 0 the spindle 17 of the lamp bracket 18 which is thus pivotally mounted for movement in an approximately horizontal plane. The lower end of the spindle 17 is adapted to rest on the dog 14 in advance of the pivotal point of the latter, thereby locking said dog securely in engaging position with respect to the teeth or ratchets.

It is obvious that when it shall be desired to adjust the lamp carrying slide, upward pressure on the head of the dog will serve to push the bracket spindle in an upward direction, until the dog is disengaged, after which the slide may be moved to the desired position, when, by releasing the dog, it will drop by gravity into engaging position with respect to the ratchets, where it will be maintained by the weight of the bracket ,spindle and the parts associated therewith.
