LIGHTING-FIXTURE SUPPORT.

Application m December 1a, 1920. Serial Il'o. 431,705.

7 To all whom it may concern! Be it known that I, BENJAMIN SoHAnrnn, a. citizen of the United States, and a reeldent of Jamaica, Long Island, in the State of New York, have invented certain newand useful Improvements in Lighting-Fixture Supports, of which the following is a specification.

This invention relates generally to a supporting structure and more particularly to an arran ement for attaching or securing a lighting fixture to a supporting element or surface, and has special reference to improvements in means for attaching or securing an electric fixture in position.

Among the more important difficulties generally encountered in such constructions are: the use of a complex construction which must be assembled and fitted in putting the fixture in place. resulting in an increase of cost of materials as well as labor in the installation of the fixture: inequalities in the element or the surface from which the fixture is to be carried or towhich it is to be attached, necessitating the use of tools, and the expenditure of time and labor; the lack of variability in the means for supporting the fixture, to accommodate variations in the fixture or in the surface or element from which the fixture is to be carried: and the necessity of using a number of alternative forms of supports dependent upon the character of the supporting element or surface to which it is to be attached.

The principal objects of my invention are: the provision of a support for a lighting fixture which is of universal application, regardless of whether outlet boxes are used or not or whether the surface or element to which the support is to be secured is the X wall itself, a pipe projecting therefrom, a

countersunk portion therein or a structure tions in the extent of the outward projection from the supporting surface of the supporting element, such as the gas pipe or the threaded part extending from the outlet box or fixture stud attached thereto; the rovision 'of' a supporting means for a xture which renders unnecessary the use of h1ckeys,crows feet, saddles and similar contrivance: the provision of an improved insulating arrangement; the provision generally of a simpler, less expensive and more efiicient lighting fixture su porting arran ment and construction, an one wherein number of arts and the initial cost is meterially re need and whereby the amount of time and labor necessary for its installation is extremely little, and one which, because of the universality of its a pli-cation, reduces the number of kinds 0 brackets that must be kept in stock.

In attaining the foregoing objects and certain additional advanta es that will either appear or be po-inte out below, I have provided a construction, one embodiment of which .is illustrated in the accompanying drawings in which- Figure 1, is a side view of the lighting fixture in' position shown partly broken away to bring to view my supporting means; Figure 2 is a perspective view'of the supporting means removed from its position of support of Figure 1;

Figure 3 is an end view of a detail;

Figure 1 is a view of a fragment of the support showing an alternative manner of securing the support in position.

Figure 5 shows a fragmentary section on line 55 of Figure 2;

Figure 6 is a detail sectional view; and

Figure 7 shows a modified embodiment of a detail illustrating a use to which my support can be put.

As will be obvious upon a reading of the ification, the embodiment of the inven tion illustrated in this application can be used equally well whether t e fixture is su ported from a side wall or from the cel ing, or even from an other character of supporting surface suc as a floor supported base. When therefore the terms wall and surface are used in the specification and claims, it is to be clearly understood that they are used merely for the purposes of convenience and in the generic sense to in dicate all the characters of supiorts to which the fixture could be attache For thepurpose of showing a manner of I as comprising the canopy 12, extension tube- 13 and electric socket 14 pendant! carried from said tube 13, in any desire or preferred manner. I want it to be clearly un; derstood that this fixture, which in the drawing is shown for the sake of convenience as a wall fixture attached to the wall A and provided with a pendant socket, may take any desired form other than that shown, such as for instance, a form adapted to-be suspended from the ceiling. By the use of my invention now to be described, this fixture' 10 is attached to or supported from a surface or wall such as A without the mutilation thereof by the use of nails, screws or other affixing means.

The fixture 10 is secured in position by a supporting structure or bracket clearly shown in Figure 2, and comprising generally two relatively adjustable members 15 and 16.

one of which is intended to serve as a mount ing frame to be. supported from or be secured to the wall or surface A and the other of which is intended to serve as an assembly member and to abut against and engage the fixture 10.

The mounting frame or member 15 is preferably though not necessarily made of a stamping of any desired metal and of. any desired or required dimensions. In the embodiment illustrated, this member 15 comprises generally the two flan es 17 and 18,

ment relatively thereto, this result being attained preferably by making the member 16 in the form of a threaded rod, received in the threaded opening 20 formed in the flan e 18.

e web or connecting portion 19 ma take any desired form and in the embodiment illustrated comprises the portions 22 and 23 substantially parallel to the length of the bracket, these portions being connected by the angularly arranged portion As a result of this arrangement the web or connecting portion 19 is arranged to the side of andoutof line with the path of movement of the screw rod 16,as well as out of the ath of the B as clearly shown in Igure 1. This result could be attained without arranging the part24 angularly to parts 22 and 23 as illustrate The .rod 16 is preferably although not necessarily threaded for its full length as as that indicated by the arrow in Fi shown, and receives on its outer end the tive movement of the tube 13 and the button' or head 26. This button 26 is preferably made of brass and its outer contour, 30 is curved as shown so as to form a harmonious design with the rest of the fixture.

In the use of thefsu port in connection with an outlet box having a threaded part extending therefromsuch as shown at C on Figure 1, the members 15 and 16 are first secured in threaded relation as shown in Figure 2. The bracket or-supporting unit 15 and 16 is then secured inposition on the pipe C by the interengagement' of the threads on the pipe C and the opening 21. This same operation will of course hold true, when the element 0 is a. gas pipe or other similar member.

The unitary fixture, comprising the memhere 12, 13 and 14 is then slipped over the unit bracket 15, 16' as shown in Figure 1, the threaded rod 16 having been positioned with reference to the member 15, so as to have its outer end project beyond the open outer end of the extension tube 13. The button or head 26 is threaded on the end of the rod 16, and, as is obvious, as soon as this button 26 is fully threaded on the rod 16, the continued rotation oi the button will cause the rod to rotate therewith, the member '15 of the bracket being held against rotation by the fact that the threads on the ipeC are of such a character that the tendiane of the member 15 to rotate with 16 will merely cause the screw threaded connection between the member 15 and the pipe 16 to be still further tightened. The rod 16 as it is rotated with the button 26, will therefore be moved longitudinally inwardly, due to the screw threaded connection between the me rabcrs 15 and 16, and the fixture 10 will thus be moved into position against the wall or surface A. The support or bracket thus far described IS an extremely sim 1e and inexpensive one,

the parts being stoc parts and few in number, readily assembled and secured in position without tools and without the loss of time. Furthermore it os'sesses the added advantage that should t e pipe C come out of the outlet box at an angle, as is frequently the case, the flange 17 can cured thereto in its angular position, and by then bending the web or connecting portion 19 of the member 15 at any point sue; the part 23 and the threaded rod 16 can be positioned so that the fixture willbe properly positioned against the wall or supporting surface. A still further advantage of my arrangement, is that the members 15 and 16 are universally adjustable, that is regardless of the length of the pipe C or of the fixture 10, there will be no necessity for cutting oif a portion of the rod 16 or of the piping or for using an extension coupling as would be the case otherwise. This result is obviously secured by the telescoping arrangement secured between the members 15 and 16. As a result-of my arrangement also, the universal adjustment will exist even where the'outlet box is countersunk in the wall, thus doing away with the necessity for extension pipings or couplings. Vhere these outlet boxes are not used, I have made my invention equally applicable and equally valuable by providing a supporting or attaching means which can be used under the circumstances, and for this purpose I have provided the flange 17 with such means, which in the embodiment illustrated, take the form of one or more openings 33, screw threaded if desired, to receive either nails or screws 34: whereby the support is secured in position.

In Figure 7 I have illustrated a suggested embodiment in which my supporting means are carried from the ceiling, and in which the button or head 26' is provided with the hook 38 from which a lighting fixture or dome may be carried or by which it may be supported.

Insulation of the supporting structure of my invention is attained by making the.

flange 17 more or less of insulating material. In the embodiment illustrated, I

- have provided an insulating bushing 40 externally threaded at 42 for its attachment in the opening 21, and internally threaded at 41 for attachment to the pipe or part C. The bushing is provided with the flange t3, the function of which is obviousfrom Figure 1. The bushing 40 can be secured in its position on the pipe 0 by any desired means such as a lock nut (not shown).

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is the following:

having the said closure mounted on its outer end and having its inner end threaded .to be screwed into said mounting frame whereby the shell is clamped against the wall and the said closure held in place over the outer end of the end body, said mounting frame including a member having a connecting web and two spaced flanges bent therefrom in the same direction and into substantial parallelism.

2. An electric lamp fixture having a mounting frame comprising a 'sheet metal member having a connecting web and two spaced flanges bent therefrom in the same direction and into substantialparallelism and adapted to be secured to a wall, a canopy like base or shell enclosing the said frame and bearing upon the wall and having its outer end open, and a closure for said open end, and a threaded rod in threaded engagement with said closure and with one of the flanges of said mounting frame for maintaining said parts in assembled condition.

3. An electric lamp fixture having a mounting frame comprising a sheet metal member having a connecting web and two spaced flanges bent therefrom in' the same direction and into substantial parallelism and adapted to be secured to a wall, a. threaded rod in threaded engagement with one of the flanges of said mounting frame, and a nut threaded on the end of said rod whereby a canopy engaged between the wall and the nut will be maintainedin adjusted position.

In testimony whereof, I have hereunto signed my name.

BENJAMIN SCI-IAEFER.
