April 29, 1930. A. LIEBOWITZ n LSGPM@ v I HICKEY AND MOUNTING THERE'FOR Filed April 25,` 1928 Patented Apr. 29, 1930 iastate PATENT OFFICE ALFRED LIEBOWITL OF MOUNT VERNON, NEW YORK HICKEY AND MOUNTING THEREFOR Application led April 23,

This invention relates to improvements in electric lighting appliances, and has particular reference to a hickey and mounting therefor.

6 An object of the invention is to provide an improved hickey of simple and practical construction which is capable of having connected thereto various sizes and types of tubes utilized as supports for electrical fixtures.

Another ob`ect is to provide a hickey or coupling member by means of which an elec. trical fixture may be securely supported in position and which will provide an effective ground connection between the fixture and wall casing that carries the hickey, thereby preventing'A the possibility of short circuits due to faulty and loose connections.

A further object is to so construct the hickey that the same may be mounted in various standard types of wall casings without altering the construction of the latter.

The above and other objects will appear I more clearly from the following detailed description, when taken in connection with the accompanying drawing, which illustrates preferred embodiments of the inventive idea.

In the drawing- Fi ure 1 is a sectional view of a casing showlng the hickey therein in operative position; l

Figure 2 is a bottom plan view;

Figure 3 is a fragmentary sectional View showing the manner of mounting the hickey in position in a standard type of casing;

Figure 4 is an elevation, partly broken away and shown in section, of the hickey illustrated in Figures 1 and 2; and

Figures 5 and 6 are plan views of slightly different Jforms of hickeys.

The present invention is designed primarily to avoid the objections arising from the use of a xture wherein a strap having but a single opening therein for receiving the screw threaded end of' a fixture tube is secured in position across the open end vof the wall casing or box through which the various electric conductors are led. It sometimes occurs that the fixture tubes suppliedy for a certain installation are of a size which will not fit the strap opening and unless the in- 1928. seria1No.272,os2. i

staller is aware of this condition before starting the work it becomes necessary to replace the straps with ones having different sized openings, thus causing more or less delay in completing the installation.

Accordingly, to overcome this difficulty, the present hickey or coupling is provided and its construction is such that it may be mounted within the confines of various standard types of casings, one of which is shown for example in the drawing. This casing 10 is adapted to be mounted in a wall or ceiling and adjacent the inner or closed end is formed with the usual openings 11 for receiving the cables 12 through which the various conduc- 65 tors 13 extend into the interior of the casing.

It is customary to fix the cables in position by means of straps 14: which straddle adjacent cables and hold the same against the inner end of the casing, the straps being `se 70 cured in position by screws 15 threaded in said end. Depending upon the points of entrance of the cables into the casing, which may be through the sides or ends thereof, the straps are arranged adjacent the sides, as '55 shown in Figures 1 and 2, or at the ends, as illustrated in Figures 5 and 6.

The hickey of the present invention is constructed in such a manner that the airlxing means for the cables above described will af- 8u ford a secure'mounting for said hickey. To this end, the hickey comprises a body 16 in the form' of a sleeve extending from a central portion 17. The opening through the body is so formed as to provide inner and 8a outer screw threaded portions 18 and 19 of different diameters while the exterior surface of said sleeve is also screw threaded, as indicated at 20, to provide a third threaded diameter. The latter threads are capable of being engaged by the internally threaded end of a fixture tube 21, as shown in Figure 1, while the other threads 18 and 19 receive the external threads of other tubes of different diameters. Thus the arrangement provides for the accommodation of fixture tubes of three different diameters.

To mount the hickey in position, the portion 17 has extending laterally therefrom on opposite sides the arms 22 provided adjame cent their extremities and on the same side edges (Figure 2) with notches 28 adapted to receive the screws 15 with said extremities interposed between the heads of the screws and the straps 14. By tightening the screws it will be obvious that the hickey will be secured in a xed position within the casing and the various conductors 13 may then be extended through the opening in the bdy 1G and the tube 21 which is threaded upon said body.

" In Figures 5 and 6, hickeys are shown which are adapted to extend lengthwise ot the casing instead of transversely, as shown in Figure 2. In this case, the arms 24 are simply made longer so as to extend between the straps 14 at the ends of the casing. In Figure 5, the extremities of the arms are provided on opposite edges with notches 25 to receive the screws 15 while in Figure 6 one extremity is shown with a notch 26 in one side edge with the other extremity having a longitudinal notch 27 therein.

What is claimed is:

1. In an electrical connection. a casing,

.straps therein for securing electric conduits in position in the casing, fasteners for fixing said straps in the casing, and a hickey in said casing including laterally extending arms engaging said straps and fasteners and secured in position by the latter.

2. In an electrical connection, a casing, straps therein for securing electric conduits in osition in the casing, screws for fixing 'sai' straps in the casing, a hickey in said casing including a body, and arms extending in opposite directions from said body and having notches therein to receive said screws, said arms engaging said straps and being secured thereto by said screws.

In testimony whereof I havel affixed my signature.
