LAMP-HANGER.

ornsso.

life all whom it may concern:

lie it known that I, WAL'rnn M. Rausnr, a citizen of the United States, residing at the city of Kalamazoo, county of Kalamazoo, State of illichigan, have invented certain new and useful Improvements in Lampllangers, of which the following is a specitication.

This invention relates to improvements .in lamp hangers.

In the use of incandescent lamps of the tungsten type, the lamps are likely to be injured by shocks or vibrations.

My improved hanger is especially designed and adapted by me for use as a hanger for incandescent lamps of this type to relieve them of shocks and vibrations, although it is desirable for use as a hanger for other styles of lamps.

The main objects of this invention are: First, to provide an improved hanger for lamps by which a lamp is supported so as to be effectively relieved of jars or vibrations of the building. Second, to provide an improved lamp hanger, which is compact and simple in structure. Third, to provide an improved lamp hanger which can be quickly and easily placed in position for use and connected to the circuit wires and to the wires of the lamp.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means,described in the following specification.

The structure described constitutes one effective embodiment of my invention. Other embodiments would be readily devised by those skilled in the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an etfective and preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this Specification of Letters Patent.

Application filed May 7, 1909.

of Fig. Fig. -'l is a perspective view of the inner sections of the hanger member disconnected from the outer sections of the hanger members. Fig. is a detail side eleration. showing the hanger members partially disconnected, to a [ford access for making the connections.

In the drawings, similar reference characters refer to similar parts throughout the several views. and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1, represents the ceiling to which the hanger is attached. The lamp 2 illustrated is of the incandescent tungsten type, the lamps proper being shown in (onventional "form. The lamp support 3 is preferably hollow or tubular and forms a conduit for the lamp circuit wires 1-. ceiling member 5 illustrated is of the crow foot type and is provided with suitable perforations (3 to receive the attaching screws T. This ceiling member 5 is provided with a threaded opening 8 to receive the nipple 9 of the upper hanger member 10, the circuit '\\'ires '11 being arranged through this open ing and the nipple. as is clearly shown in Fig. 3. The lower hanger member 12 is provided with an internally-threaded nipple 18 to receive the upper end of the lamp support 3, the circuit wires 4; being arranged therethrough. See Fig. 2. The hanger members and l) are preferably stirrup-like in form, as illustrated, and are arranged in an pp sitely-disposcd telescoping relation, the lower member being inverted. These mem bers are preferably madenp of detachable section, the detachable portions comprising the inner ends 14; which have side portions or arms to thereon, the arms being secured to the outer sections of the members by suitable screws, as 16. The ends 1 L are provided with guide openings or slots 18 to receive the arms of the opposite member. slots or guides are so arranged as to permit a limited swinging or oscillating movement of the lower men'iber, which is supported upon the upper member by the coiled spring 1:). cally-coiled type, and is arranged between the inner ends of the hanger members, with its apex upwardly, the base of the spring resting on the inner end of the upper hanger member, the inner end of the lower hanger member resting on the spring. The openlng l7 in the inner end of the lower hanger The These This spring is preferably of the hclimember is provided with a thimble 20 on which the upper end of the spring is engaged. Byproviding this form of spring, a very resllient sprlng may be secured, and the spring tends to hold the lower hanger member in an upright position, allowing the lamp to oscillate, as stated, and supporting it effectively, to relieve it of shocks or vibrations of the ceiling.

In the outer ends of the hanger members are insulating blocks 21, in which the binding posts 22 are mounted. These binding posts are connected by the circuit coupling wires 23, the coupling wires being arranged through the openings 17 in the inner ends of the hanger members through the spring. The circuit wires 4. and 11 are connected to these binding posts. These coupling wires 23 are of such length as to permit the movement of the lower hanger member as the spring is collapsed. The thimble 20 also serves as a shield for the coupling wires so that they are not worn or abraided by movement of the lower hanger member.

In placing the hanger, one pair of the screws 16 is removed,that is,one screw on each side, when the inner sections of the hangers can be swung off on the other pair of screws, as indicated by the dotted lines in Fig. 5, to permit the convenient attachment of the circuit wires to the binding posts, so that the hanger may be very quickly and easily placed and the proper connect-ions made.

I preferably provide the hanger with a casing 2a, which is, in the structure illustrated, secured to the ceiling by suitable screws, as 2-5, the lower end of the casing having an opening therein of suflicient size to permit the free movement of the support 3 therein. It is obvious that the casing might be otherwise mounted.

By my improvements, I provide a hanger which enables the use of lamps of the tungsten type in factories and other places in which they could not be used otherwise on account of the shocks, jars and vibrations to which they would be subjected.

My improved hanger is comparatively simple and economincal in structure and can be very quickly placed and electrical couplings made, as described.

I have illustrated and described the same in detail herein in the form preferred by me in an embodiment which I have found satisfactory. I desire, however, to be understood as claiming the same broadly as well as in detail in the form illustrated.
