OF CHICAGO, ILLINOIS, ASSIGNOR TO AOORN BRASS MANUFACTURING COMPANY,A CORPORATION OF ILLINOIS.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed Apri125, 1908. Serial No. 429,277.

To all whom 'it may concern:

Be it known that I, HARTT H. EASON, a citizen of the United States, residing in Ohicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Lamp and Feeding- Tube Connections and Supports, of which the following is a specification.

This invention relates to that class of gas lamps or fixtures having a supporting bracket which is provided with an upper ring portion adapted to support the hollow wires or feeding tubes forming part of a gas or gasolene lighting system, and having depending clamping arms adapted to support and permit the adjustment of-the lamp fixture properafter the hollow Wires or tubes of the 'ghting system are first mounted in position and supported by one or a series of such clamping and tube-supporting bracket members.

The principal object of the invention is to provide a simple, economical and efficient combined hollow wire and gas lamp or fixture supporting bracket.

A further object of the invention is to provide a combined hollow wire and gas lamp or fixture supporting bracket, having a grooved upper ring portion and depending clamping arms, so constructed that a series of such brackets may be employed to support the horizontal or main wires or tubes of a gas or asolene lighting system, and enable the amps or fixtures to be mounted and adjusted in said brackets, and the tubes leading to the lamps or fixtures to be connected with the tubes of the main wiring or feeding. tube system after the laying of the feeding tubes of the main system and the mounting of the clam ing and tube supporting brackets is comp eted.

Other and further obj ectsof the invention will appear from an examination ofthe drawings and the following description and claims.

The invention I consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accom anying drawings Figure 1 is a view in side e evation of a plurality of my improved upper bracket mem ers in position Fig. 2, a central sectional view in elevation of my improved tube supporting and fixture clamping bracket mem er connected with a gasolene lamp and showing the manner of connecting and supporting the tubes and fixture; Fig. 3, a plan view of the bracket shown in liigs. 1 and 2. and Fig. 4, a bottom view of the same.

In constructing a combined lamp and feeding tube supporting and connecting bracket in accordance with my improvements, I provide a bracket or bracket member a formed preferably of cast metal and consisting of an upper ring portion b having radial grooves 0 preferably in its upper side, in position to old hollow wires or feeding tubes d in position between the upper ring or grooved Wiresupporting portion of the bracket and ceiling or support to Which the bracket is to be attached. Depending arms e preferably integral with the upper feeding-tube supporting or ring portion of the bracket, extend downward and toward the center on opposite sides of the vertical or axial center of the ring portion of the bracket and are each provided with substantially semi-circular grooves f at their lower ends respectively. These grooves form a substantially cylindrical opening between the lower ends ofthe said arms, which is adapted to receive the upper portion of a fixture, g which may be in the form of a chandelier, depending tubular arm or any other desired type of lamp bracket proper or supporting device connected direct y with or forming a direct support for a lamp or burner, and having a smooth or nonthreaded upper portion adapted to be clamped between and adjusted to the desired position with relation to the bracket member or bracket a, and the feeding tubes su plorted thereby.

e depending arms 6 are sufficiently flexible to permit them to be spread apart very slightly but to a sufficient extent to admit the upper end of the fixture or lamp engaging and supporting member g when such spreading is necessary by reason of the size of the member 9. Ordinarily, however, the spreading of the arms is not necessary or desirable, and their flexibility is desirable principally for the purpose of enabling them to be clamped to the member or lamp supporting tube 9 in an efiicient manner, so as to enable the latter and the feeding tube or hollow wire 72, contained therein to be adjusted with the necessary degree of accuracy to be properly connected with the T-joint 'i and thereby with the feeding tubes (1 by means of flanged nuts 8 and 0 and nipples t. The lower end of each depending arm e is provided with a lat erally projecting portion j on each side thereof suitably perforated, and in one or both sides suitably threaded, to admit a clamping screw k. These screws may each be provided with a nut if desired, and are adapted to clamp the spring arms 6 firmly into supporting engagement with the upper cylindrical portion of the depending member 9.

The upper ring portion of the bracket a is provided with a plurality of perforations Zfor receiving screws, not shown, by means of which the bracket is secured to the ceiling of a room or to a desirable support, and the upper radial portions it between the radial grooves e have their upper surfaces all on the same plane and are arranged at such close intervals that the bracket may be turned to any desired position to enable the screws to enter a rafter or any desired portion of a rafter or othersupport without seriously affectingor making it necessary to change the position of the feeding tubes or hollow wires by reason of the positions of the grooves or upper radial portions of the ring which are between the grooves.

By the above arrangement it will be seen that an entire system of hollow wiring may be completed, all of the feeding tubes which compose the system being sup orted by the above described combined ho ow wire and vfixture orlamp supporting bracket members.

Any desired number of said bracket members may be thus mounted in positions corresponding with desiredpositions in which the fixtures or lamps are to be mounted. The brackets support the feeding tubes in the grooved portion of the upper rings so as to hold them in just the position in which they are tobe used. The depending arms of each of these bracket members being smooth, or

.without threads, and the upper end of the fixture or lamp which is to be clamped between said arms, being likewise smooth and free from threads, it will be readiiy seen that the tubes which extend vertically inside of the fixture may be fixed to the fixture or lamp in the factory, and the connection with the hollow wires of the feeding tube system may be made after the construction of the system is complete and after the improved upper bracket members are mounted in place. The facility with which the fixtures may be mounted and connected with the hollow wires or feeding tubes of a lighting system is thus greatly increased. The facility with which the parts of the fixture including the vertical tube It the outer tube or fixture member 9, the nut 0, the nipple p, the nut g and the lamp 1", can be assembled is also ward and inward and provided with a space between the ends of said arms and means for ing said depending arms together.

v n a bracket of the class described, the comblnation of a ring portion provided with radial grooves in its upper side for receiving clam feeding tubes to be supported by the bracket,

and having flexible depending arms on the under side of said ring portion extending downward and inward and providedwith a space between the lower ends of said arms, and means for clamping said arms in engagement with a device to be supported thereby.

3. In a bracket of the class described, the combination of an annular upper portion provided with radial openings for receiving feedmg tubes and having flexible depending arm portions on its under side extending downward and inward and normally out of contact with each other, and screw mechanism mounted in and connecting the lower ends of said arm portions.
