Application April 30, 1947, Serial No. 744,896 2 Claims. (Cl. 173-328) 1 This invention relates to fluorescent -lighting fixtures.

It is an object of the present invention to provide an end bracket carrying contact terminal for delivering current to a fluorescent tubewhich is supported from the same whichis divided in two parts and so constructed that the parts can be separated and such wherein that one of l the parts i-s broken only the one part need to be replaced.

Another object of the present invention is to provide a bracket for supporting a fluorescent lamp which cannot be easily broken and which will permit the attachment of the fluorescent lamp to one of its parts so that the part may be in turn in difilcult locations the mounting of the lamp may be facilitated.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a fragmentary view of a fluorescent lamp connected with the bracket embodying the features of the present invention. l

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 2.

Fig. 4 is a fragmentary and cross-sectional view of a. modified form of' bracket construction.

Fig. 5 is a collective view of the coupling parts of the bracket shown in Fig. 4.

Fig. 6 is a rear elevational view of the bracket construction shown in Fig. 4 and illustrating the manner in which the parts are disposed to connect them together.

Fig. 7 is a top plan view of the screw contact terminal.

Fig. 8 is a side elevational view of the terminal and taken on line 9 9 of Fig. 7.

Referring now to the figures, I represents a base having a fixed part II of a bracket thereon. This fixed part II has a dovetail groove I2 in its front face for receiving a dovetail projection I3 of a separable bracket part I4. 'Ihe bracket part II has openings or chambers I therein in which there are spring pressed terminal elements I6 adapted to project through the front of the bracket and into the dovetail groove I2 thereof. These terminals I6 will engage with heads Il of screws extending from the rear of the front bracket part I4. These heads I1 are hollowed or provided with a hole I8 for receiving the rounded end of the terminals IB. A slot I9 is provided l5 connected to the fixed part of the bracket whereby 2 lon the head for the attachment thereto of a screw driver. The hole I9 is not disposed at the same depth as the slot I9 so that the end of the screw driver will have engagement throughout 4the entire length of the slot I9. Extending `from the heads I'l of the screw is a shank 2I whichA is threadingly connected to a spring clip terminal 22 which has a bent portion 23 for receiving a pin 24 of a fluorescent tube 25. 'Ihe forward end of the bracket part I4 has the usual opening 26 through which the pins 24 are extended for engagement with the contact portions 23 of the contact spring 22.

It will be apparent that when the bracket part I4 visslid downwardly -so that its dovetail projection I3 is received in the dovetail groove I2 of the bracket part I I that an engagement will be made of the pin terminals I6 with the holes in the heads I1. By this engagement the bracket will be rigid and become a unitary structure. The bracket part I4 will be retained against further sliding movement by the contacts or terminals themselves and at the same time a good circuit connection is established.

Referring now particularly to Fig-s. 4, 5, and 6,

there is shown a modified form of bracket where there is a bracket part 21 having a central proward end of the part 33 is of' similar construction to that shown in Fig. 2. l

While-various changes may be made in the detailed construction, it shall be understood that such changes shall be within the lspirit and scope of the present invention as defined by the appended claims.

' Having thus set forth and disclosed the nature of this invention, what is claimed is:

1. A bracket mounting for a fluorescent lamp comprising a base, a, two part end bracket extending from the base and adapted to receive the fluorescent lamp, one part of the bracket being fixed to the base, having spring biased pin terminals, the other part being separable from the Cil to engage respectively with the spring biased pin 3 terminals, means for releasably securing the parts together including the provision o! a dovetail groove on one part and a dovetail projection on the other part adapted to slidably engage with end terminal of a uorescent lamp, one of the' parts having spring pressed pin terminals, the other part having screw terminals with heads which are hoiiowed to receive the ends of the pin terminals whereby to prevent the displacement of 4 the parts from one another when connected together, the said parts (having guiding means extending between the same for causing the same to be fitted together in tight engagement with one another, the pin terminals engaging with the screw heads at the end of the tting movement.
