WILLIAM E. JANNESS Patented June 16, 1953 ELECTRIC LIGHTING FIXTURE SUPPORT 'William E.Janness,' Wheeling, Ill., assignor to Lighting Products, Inc., Highland Park, 111., a corporation of Illinois Application ctober 28, 1947, Serial No. 782,663

This invention relates in general to a hanger for electric lighting fixtures and is more particularly described in connection with the straight gas-filled tubing types of lamps which are now commonly installed directly upon the ceiling or in a recess or trou'ghbetwe'en frames, joists, or other supports so that the lower edge or bottom of the fixture will be flush with the ceiling or with the lower edges of the supports.

An important'object of the invention is to provide a flexible hanger which is acceptable of much adjustment in its mounting so far as the ceiling, troughs, joists, or other mountings are concerned and also to provide a quickly adjustable and flexible supporting means for attaching a tubular type lamp housing thereto.

. A further objectof the invention is to provide improved means for adjustably connecting a tubular lamp housing to a hanger, to move the lamp housing transversely in the hanger, to raise or lower either side of the housing in the hanger.

Still a further object of the'invention isito provide a hanger which may be variously connected to the ceiling,to side joists, or other supports, to attach the hanger by rivets, screws, angle brackets, and T-bar supports.

' A further object of the invention is to provide a hanger of this kind which has adjusting and supporting means extending through the top of the lamp housing so that after the lamp has been installed, it may be adjusted in the hanger vertically, laterally, or in transverse inclination from the inside of the lamp housing without removing the lamp housing or the hanger.

Other objects of the invention will appear in the specification and will be apparent from the accompanying drawings in which,

Fig. 10 is a View in vertical section of the hanger as secured to a' lamp housing.

For mounting electric lighting fixtures of the straight tubular'lamp type, it is current practice to locate the lamp housing in wall or ceiling troughs between joists, furring, or other supports with the outer or lower edges of the fixtures fiush with the surface in which the recesses or troughs are provided.

Since it is not convenient to work upon the lamp supporting means after the wall parts are in place, the present invention provides means for installing the'hangers' of this invention at spaced distances apart between the various wall supports so that it necessary only to insert the fixture housings within the lamp trough, to position the housing so that the projections of the hanger will extend through perforations suitably provided in the top of the housing and then to insert fastening means from the inside of the housing through the hanger and in engagement with the fastening means of the hanger not only to supportthe lamp housing, but also to adjust it vertically and transversely in the hanger and to vary the inclination of the lamp housing in the hanger asdesired. Referring now more particularly to the drawmgs, the hanger It as shown more clearly in Figs. 1 and 2 comprises a channel-shaped yoke with parallel ends having anumber of openings I 2 extending through the central web of each end and the channel opening inwardly.

In the cross piece of the hanger is a central slot I4 located in a counter-sunk portion l3 and two end perforations l5. In the side edges of this portion of the channel are slots l1, one at each side of thecenter, registering with each other in opposite edges of the channel.

A short channel bar 20 is disposed within the hanger and has a fastening screw 2| extending through the slot I4 and through the bar with a slot 22 in the end of the screw opposite the head 'so that it may ,be turned by a screwdriver from either end of the screw. Mounted at each side of the bar 2|] upon a pivot. 24 are

links

25 and 26 whichextend within the hanger [0, the

upper end of each link being perforated and disposed adjacent one of the slots I! so that a cotter pin 26 may be inserted therethrough and through the perforation of the corresponding link connected to the other side of the bar 20. At the outer sides of the hanger Ill, each cotter pin is provided with washers 21 for holding it in place and asisting its movement longitudinally of the slots ll. Extending through each end of the bar from the outer and (under) side thereof is a set screw of sufficient length and adapted to engage the inner side of the connecting web of the hanger. By adjusting the central screw 2i and these end rscrews 3ll, the.

height of the bar 20 or its distance from'the hanger it! may be adjusted and set, and because of the slots 14 and H, the bar 20 may be adjusted transversely in the hanger, that is longitudinally of the hanger itself.

Secured to the channel bar 20 and extending through it from the outer or under side are screws 32 located between the central screw 21 and the end screw 30, and these screws 32 are adapted to be inserted through suitable openings 34 in the top 35 of a lamp housing 36. Attachable at the ends of the screws 32 as they protrude through the top of the housing are wing nuts 38 or other suitable fastening devices for engaging the screws and holding the fixture in place. The top of a lamp housing is also provided with a central opening 39 through which the end of the screw 2| may protrude or through which the slot in the end of the screw may be engaged by means of a screwdriver from the inside of the lamp housing. Openings 40 are also provided in the top of the lamp housing through which the end screws 30 may be inserted through the plate 20 to engage the inside of the hanger H] for the adjustment purposes as set forth.

In the application of this hanger for supporting a lamp fixture, it may be desired to support the fixture directly from a wall or ceiling 42 .as shown in Fig. 7. In this case, fastening screws 43 are inserted through the openings l5 in the connecting portion of the hanger. For this type of installation, the central slot I4 is located in the counter-sunk recess l3 so that the head of the screw 2| is freely movable for the transverse adjustment of the bar 20.

The hanger may also be located directly between parallel joists 45 or other supports by interposing blocks 46 between the ends of the hanger and the joists, the hanger being secured by fastening screws 48 inserted from the inner sides of the hanger into the blocks and the blocks being secured to the joists 45 in any suitable manner.

As shown in Fig. 5, lamps may be installed in the space between wood furring 50 by mounting the hanger upon angle brackets 52 at the upper edges of the furring, a, fastening screw 53 being inserted through an opening 54 (Fig. 8) of the bracket and fastening screws 55 (see Fig. 3) being connected through perforations 56 (Fig. 8) in the other portion of the bracket.

As shown in Fig. 4 and Fig. 9, the ends of the,

hanger may be attached to fasteners Bl! by means of screws or bolts inserted through openings Bl in the fastener and through the openings i2 of the hanger. At the under side of the fastener are inwardly turned flanges 53 adapted to engage a T-bar 65 connected to side pieces 66 at the outer edges of the lamp fixture housing.

For mounting lamp housings of this kind, projecting flanges 1U are usually provided at the lower or outer side edges to fit between the supports which form the trough and the outer edges of the flanges may be substantially flush with the outer edges of the hanger so that a hanger may be inserted in any location where the lamp is to be supported. Each end as 12 of the lamp housing may be provided with a partially severed knock-out plug 13 by means of which adjacent lamp housings in line with each other may be electrically connected for operation together.

With this construction, the hanger may be applied in a Variety of ways some of which are shown by way of illustration and in each installation the lamp housing may be adjusted relatively to the hanger before the hanger is applied, and also after the fixture is in place. In some cases, the hanger may be applied to the lamp housing before the hanger is applied to its support, and

in other installations, the hangers are placed in position and then the lamp housings are connected to the hangers. Since the

openings

34, 35 and 40 are provided in the top of the lamp housing for receiving the adjusting screws from the hanger, it is necessary to locate the hangers at spaced distances apart so that the lamp housings may be applied thereto. After the fixture has been installed, if it is necessary to move the fixture transversely to adjust the height of the fixture or to adjust the transverse inclination of the fixture, this may all be accomplished from the inside of the housing when removing it or the hanger from its set position. The lamp housing may be moved transversely by means of the hanger slots [4 and 11 and the fixture may be adjusted vertically in an inclination by manipulating the central screw 2| and the side set screws 30 from the inside of the housing. In the tubular lamp type of fixture, these fastening screws 2| and 30 may be accessible without removing the tubular lamps, but even if it is necessary to remove the tubular lamps, it is a simple matter to do so to adjust the housing in the hanger.

While the preferred construction and several applications have been described in some detail, it should be regarded by way of example and illustration rather than a limitation or restriction of the invention, as various changes in the construction, combination and arrangement of the several parts may be made without departing from the spirit and scope of the invention.
