P. L sNEsKY Loom PLQ@ ELECTRIC FIXTURES Filed June 412?" 119,32 4
APatented Mar. 18, i924.
PAUL LESNESKY, OF DETROIT, MICHIGAN.
LOOM PLATE FOB EIE'C'IIRIICZ FIXTURES.
Application filed June 12, 1922. Serial No. 567,728.
To all whom 'it may concern:
Be it known that l, PAUL LEsNnsKY, a eitinen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Loom Plate -tor Electric Fixtures, of which the 'following is a specilication.
This invention relates to loom plates for supporting electric lixtures. n
The object of the invention is to providea loom plate and mounting therefor adapted to be supported by the licor oists of a building and to torni a hanger for supporting an electric iixture, and in which the formation and association ot the parts is such as to permit of rapid assembly in an interlockofthe plate longitudinally of the mounting and also for the retention. of the parts 1n the desired vposition of adjustment without necessitating the `ei'nployment of bolts, set screws or similar tensioning members.
A preferred embodiment of the invention is illustrated. inthe accompanying drawings, in, which,
Fig. 1 is a bottoni view of the loom plate and its mounting indicating by dashed lilies the joists supporting the same.
F1g. 2 is a side elevation 'View of the parts shown in Fig. l.
F ig. 3 is an enlarged longitudinal sectional View taken on line 3--3 of Fig. 1.
Fig. fi is a cross-sectional view taken on line f-4 of Fig. l.
In these views the reference character l indicates a peripherally flanged loom plate havin the usual circular series of plugged loom openings 2. The plate 1 centrally ear* ries a depending stud bolt 3, the shank there of passing through an opening 4 in the plate, and having its head 5 seating on top of the plate. Said head engages in a channel shaped depression 6 lformed in the face of the plate and has beveled edges 5 registering with the sides of said depression to prevent turning of the bolt. The plate is carried by a bar 7, preferably of metal reetangular in torni, which bar is adapted to span adjacent joists 8 and is formed terminally with screw or nail holes 9 adapting'it to be fastened to said joists.
The mounting of the loom plate. u on the bar 7 is eli'ected by a bridge mem )er 10,
ing relation so as to provide for adjustment y iaee groored lo receive the lower face of said bar, as is clearly seen in Fig. li, and thus the bar holds the stud against rotation and additionally prevents any'upward shitting oit the stud from its proper osition, as shown. Any shitting of the lbom plate lengtlm'ise upon the bar is resisted by the i'rietional engagement of the bar between the stud head 5 and the member 10. The resistance to such movement, however, is so predetermined as to permit such adjustment ol the plate upon the bar as maybe neces'- sary to properly install the device. It is to be understood that the stud 3 is adapted for engagement by any suitable electric fixture (not shown) for lights or other purposes, such as is commonly supported from walls or ceilings.
v It is a distinctive .teature of the described invention that proper positioning of the loom plate upon its supporting bar is ac- Acomplished without manipulation of any nuts or screws, and also that the desired rigid. relation between the stud bolt 3 and the loom plate .is established without such manipulation. Furthermore these results are'obtained without especiallyA machining or otherwise fashioning the rectangular supporting bar.
wWhat l claim is:
l. The combination with a supporting bar, of a loom plate, and a bridge member having arched extremities embracing said har and rigidlyk secured to said plate, said bridge having a deflected portion engaging the bar and frietionally resisting movement of said plate longitudinally of said bar.
2. The combination with a supporting bar, oi a loom plate, a bridge member having arched extremities embracing said bar' and secured to said plate, said bridge having a deiiected intermediate portion frictionally engaging said bar, and a fixture support extending through the loom plate and having ahead portion interposed between said bar and plate and. co-aetng 'with said bridge to rctenally resist movement of said plate along Sad bar.
3. The combination with a suppertmg bar, of a loom plate, a1 bridge member llering its extremities secured to said. plate and* ntermediately deflected to eugege seid i3-1351"l` and a lxture support extendlug tluougm said plate having a head between said bar and. plate recessed to 'receive said. bar, said. head ce-aetiug with said bridge to friction-qll): restrain said members against relative movement.
