SUPPORT FOR ELECTRICAL FIXTURES.

i Application filed March 27, 1922. Serial No. 546,951. i

To all whom it may, concern:

Be it known that I, BURTON A. VAND a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Supports for Electrical Fixtures, of which the following is a specification. A

The present invention relates to supports for electrical fixtures and an object thereof is to provide an improved adjustable bridge adapted to be secured within a ceiling to be supported by two joists. Another object of the invention is to provide a bridge with position-defining devices which will so cate the bridge member on the joists that the fixture support on the bridge will be in proper position with reference to the laths and the plaster of the ceiling. Still another object of the invention is to provide a bridge which may be inexpensively made from sheet material and will have sufiicient strength to support the electrical fixtures on the bridge in such a manner that the latter may be adjusted and the securing means will also act to prevent a separation. of the members of the bridge. A further object of the invention is to. provide a loom holder which will support, in proper position in a ceiling, the looms through which the conductors pass through the ceiling. A still further object of the invention is to provide a loom holder which will also act as a support for the laths meeting such loom holder.

To these and other ends, the invention consists of"c'ertain parts and combinations of pants; all of which will be hereinafter I described, the novel features being pomted out in the appended claims.

In the drawings:

Fig. 8 is a section on the line 88, Fig. 4.

In the illustrated embodiment of the invention. there is employed a supporting bridge adapted to be secured to two joists 1 in order to extend between them. This bridge is formed of two members 2 and 3, both, in this instance, made from sheet metal bent into channel form, one being received within the other, their channel faces being opposed. The outer member has preferably at its inner end two lugs 4 bent inwardly over the outer face of the inner member to confine the inner member against lateral displacement at this point. Each member of the bridge has at the outer end thereof an anchoring means for abutment with and adapted to e secured to the joists 1. In this instance, the abutting and anchoring means is provided with positioning means for cooperating with the loweredges of the joists in order to determine the horizontal position of the bridge. This result is -'secured, in this instance, by providing each of the members 2 and 3 with two lugs 5 and 6, the former being shorter than the othei and both being formed by extending thc side walls of the two members beyond the bottom of the channel and below said extended positions at right angles. The edges 5 and 6 of these two pieces form the posi tioning means, the edges 5 on the two members of the bridge being situated at an equal distance from the longitudinal axis. of the bridge, the edges 6 on the two members being likewise positioned. These edges are adapted to be brought into alinement with the under edge of the joists 1' for defining the horizontal position of the bridge.

There may be associated with the bridge, a loom holder 7, Whichhas an externally threaded projection 8 or other means through which any suitable fixture may be attached. This loom holder is preferably supported from the bridge through an inverted U shaped securing device 9, the arms of which lie in ,close relation to the opposite sides of the brid e and depend below the latter. Between tl ese depending arms, a reduced portion 10 on an upwardly proecting portion of the loom holder 7 is extended, being held in this position by a bolt 11, the upper end of the loom holder abutting the under side of the bridge. 'The through which the looms 13 are passed,

.- these looms serving as non-conducting coverings for the conductors 14 extendin from insulators 15 secured to the oppose faces of the joists 1. On opposite 'SldGS of the line formed by the two openings through which the conductor looms 13 pass, the loom holder 7 is provided with two seats 16 which formrests for the laths 17, the vertical height of the loomfholder being so proportioned to the len the of the arms -5 that the seats '6 will be orizontally alined with the under-surfaces of the laths 17 secured to the joists 1. The thickness of the loom holder below the seat 16 is substantially equal to the thickness of the plaster applied to the laths so that the under face of the 100m holder with the exce tion ofbolts 10" are secured tothe outlet box and -also to a fixture anchoring member'19 of I known construction arranged within the said joists.

box.

From the foregoin itwill be seen that therehas been provided-abridge adapted to be supported 'by the two joists and adjustnd to the distance between his-bridge is formed by two members, one received within the other and able to corres preferably both of channel formation with their channel faces -opposed. At opposite ends of the bridge, anchoring and abutment means is provided which has thereon'posidifferent horizontal. to the lower edges 0 the joists. Themeans tioning means for positioning the bridge in ositions with reference which secures the part to be sus "ended from the bridge also acts to hold t e two 1 members of the bridge together, being preferably in'the form of an inverted U shaped member having its ends detachably secured to the part to be suspended. iA loom holder may be suspended from the bridge by said part and has .openings through which the conductor looms pass to theroom below the ceiling, On opposite sides of this loom' holder rests are provided for the ends of laths secured to the joists. The positioning means. are such that these rests may be arranged in proper position for laths secured to the under faces of the joists. The

positioning means also properly positions the bridge for outlet boxes of difierent.

de ths. 1

l Vhat I claim as my invention and desire to secure by Letters Patent is:

1. A support for electrical fixtures comprisin a bridge and abutments at opposite ends t ereof, each abutment formedwith a pluralit pf position defining'devices having ends ocated at different distances from the longitudinal axis of the bridge.

2. A support for electrical fixtures comprising abridge and abutments at opposite ends of the bridge each abutment formed by two oppositely extending projections of different lengths, the edge of-each projection having ends situated at distances from the longitudinal axis of the bridge equal to the distance that the edge of one of the projections at the opposite ends of the bridge is situated from such axis.

- 3. A, support for electrical fixtures comprising a bridge embodying two members, one of which has a'channel .in a vertical side and the other of which is received with-' in the channelled member and is flush with the edges of the channel, anchoring abutments at opposite ends of the bridge, andv a fixture securing member of inverted U shaped formq fitted about the channeled member in abutment with the top and verti'cal. wall thereof and "also in abutment with that wall of the other member which is flush with theedges of the channelled member, combined with a fixture secured to the ends oi the U- sha ting the under] wal of the channelled member 4. A support for electrical fixtures com: prising two. channel members one of which is received within the other and the channel.

in the members being opposed, and anchoring, lugs extending outwardly in opposite direction from the side walls of each of the channel members, said in at each end having different lengths, an each of said lugs d member and abuthaving its outer edge positioned to the same distance from the longitudinal axis of the hanger that a lug in the opposite end has its edge positioned fromsuc axis. t 5. In combination with abridge, an'invertedv U shaped member fitted about the bridge and having its arms deoendin below the latter, and a loom holder having a 'projectiofi extending between said arms and engaging the under side of the bridge, and a bolt passing through'the arms and the projection of the loom holder.
