@C QI M INVENTOR M ATTORNEY I BY TED STATES JOSEPH SACI-IS, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE SACHS LABORA- TORIES, INCORPORATED, 0F HARTFORD, CONNECTICUT, A CORPORATION OE CON- NECTICUT.

LAMP-CORD ADJUSTER AND THE LIKE.

T 0 all whom if may concern Be it known that I, JOSEPH SACI-rs, a citizen of the United States, and resident of Hartford, in the county of I-Iartfo-rd and State of Connecticut7 have invented certain new and useful Improvements in Lamp- Cord Adjusters and the Like, of which the fol-p lowing is a specification.

rI he object of the invention is to produce al device of the class specified having features of novelty and advantage.

In the drawings Figure l is a side elevation of the complete device. Fig. 2 is an edge view thereof. Fig. 3 is a central vertical section of the upper member. Fig. 4 is an inside view of one side thereof. Fig. 5 is an inside view of the opposite side. Fig. 6 is a transverse section of the lower member. Fig. 7 is an inside view of one side thereof. Fig. 8 is an inside view of the other side thereof. Fig. 9 is a perspective view of one of the weights.

I have shown my invention in connection with its use for the purpose of adjusting the position of an incandescent lamp, although it is evident that the adjuster can be used for other purposes. The description will be confined to the embodiment which has been selected for illustration.

In the drawings, a denotes the base of the rosette which is fastened to the ceiling and b the removable cap to which the conductor c is connected.

The adjuster comprises an upper member l and a lower member 20. The cable c passes through a direct channel 2 in the upper member, thence through a return channel in the lower member formed by the pulley QQ, thence up and through a return channel in the ripper member formed by the pulley Ll, thence down and through a direct channel 2l in the lower member. The upper member is supported by the chains Z which are attached to the ceiling in any desired way as by the hooks e-e whose ends slip under the rosette, thus relieving the cable and rosettecap from the strain of supporting the weight of the parts of the adjuster. The lower memberA is weighted to meet the requirements of a given case, but always in such a i manner that the light will stay where it is positioned.

In detail the ripper member l is formed of insulating material such as porcelain and is made in two parts 5 6, These two parts Speccaton of Letters Patent.

are oppositely grooved as at 77 so that when fitted together they form the direct channel 2 and preferably the cable is of such a size that it lits snugly in this channel, the channel being given a curved form so as to assist in the frictional attachment of the upper member to the cable. The section 6 is provided with a hub 8 upon which the pulley 4L is mounted. The two parts are secured together by a pin l0 under the heads of which lie the ends of the wire bands 11 to which the chains CZ are attached. In detail the lower member 2O is also made of insulating material and is formed in two parts 30-31, the part 31 having a hub 32 on which the pulley 22 is mounted. Extending centrally across the inner face of the part 30 is a groove 84 forming, with the grooved top and bottom, projections 35-36 on the part 31 and the grooved end 37 of the hub 32. Recesses 38 are provided in one or both faces of the lower member to receive weights 39 the number or size of which can be varied to increase or decrease the weight of the lower member as desired. rI`he two parts of the lower member are held together by the spring ring 40 or in any other desirable manner. To lower the light it is only necessary to draw down on the end of the cable, which action, of course, draws the upper and lower members nearer together. To raise the light it is only necessary to lift up on the lower end of the cable when the weight of the lower member 2O will cause it to drop separating the upper and lower members and taking up the slack of the cable.

All parts of the upper member except the pin l0 and the wire bands 11 may be made of insulating material and all parts of the lower member, except the spring ring which holds the two parts together, may be of insulating material. The chains CZ provide for supporting the complete device independently of the cable and rosette, thus removing any danger of the rosette cap being pulled out during the ordinary use of the apparatus.

It is to be particularly noted that by the herein described construction and arrangement of parts the upper and lower ends of the cable are in substantial alinement affording a symmetrical arrangement and obviating any possibility of the various twisted together due to the sectional construction.

The device can be applied to an existing installation by merely positioning the cable properly in the channels and clamping the parts together.

am aware that the device as herein illustrated and described is susceptible of alterations and modifications and of other uses than as an adjustable support for an incandescent lamp and it is not my intention that the appended claims shall be limited to the exact structure or use illustrated.

I claim my invention:

l. In a device of the character described the combination with a supporting cord, of an adjuster therefor comprising an upper and a lower member each of which is provided with a, direct and return channel through which the cord passes, means for supporting the upper member independently of the cord, said lower member being supported by the cord from said upper member.
