HULL.
Patented May 12 UNITED STATES PATENT CFFIGE.
LIVERUS HULL, OF GHARLESTOWN, ASSIGNOR TO TUCKER MANUFACTURING COMPANY, OF BOSTON, MASSACHUSETTS LAM P-PENDANTS.
Specification forming part of Letters Patent No. 150,861, dated May 12, 1874 application filed March 11, 1874.
To all whom it may concern: Be it known that I, LIVERUS HULL, of Gharlestown, of the State of Massachusetts, have invented a new and useful Improvement in Lamp-Pendants and do hereby declare the same to be fully described in the follow ing specification and represented in the accompanying drawings, of which Figure 1 is a front elevation, and Fig. 2 a vertical section, of an extension-lamp or chandelier pendant, provided with my invention.
In such drawings, instead of the tube A, to which the lamp or burner is to be aflixed or suspended, being made to slide on a solid rod, it has a tube, B, to slide lengthwise within it, and upon such a rod, the clamp-lever a of the clamping apparatus shown at '0 being to embrace the said tube 13. The tube B, near its upper end, is furnished with a rosette, D, and a tubular neck, F, and a clamp-screw, E, the latter being screwed laterally into the neck and against the supporting-rod G, upon which the neck and tube slide longitudinally, the clamp-screw serving to fix the neck to the rod. The said rod G, at its upper end, is provided with a disk or head, H, from which there is projected, as shown, a male screw, I, and a coupling or tube, K, provided with a female screw, 0. The tube is concentric with the screw I, all being as shown.
The addition of the tube B and its clampscrew E tothe rod G, and the tube A provided with the clamp mechanism 0, (which is described and claimed by me in the United States Patent N 0. 142,107, recently taken out by me,) enables the pendant to be adapted to rooms of different heights. Furthermore, with-the screw I and screwcoupling K, the pendant may be either screwed into a ceiling or upon the end of a gas conduit or tube projecting therefrom, the disk or head H serving to enable a person to readily revolve, by one or both hands, the rod and the screw and coup ling, in order to eflect either the attachment of the pendant to a ceiling or gas-pipe, or the removal of such pendant from such ceiling or gas-pipe, as circumstances may require.
From the above it will be seen, with respect to the co-operative action of the screw I and the coupling K, that when the part H is used to sustain the pendant the coupling K acts as a shoulder against the ceiling; also, that when the coupling K is used on a gas-conduit the screw I will extend up into the said conduit,
and not only allow the coupling to be screwed to it, but serve to steady the connection.
Upon the lower end of the short rod (1, projecting down from the slide-tube A, a screw, h, is cut to receive the lamp or chandelier, or a nut, L, provided with one or two hooks or hooked arms, 2' 1'. Upon either one of such arms a German study-lamp may be hung, and the apparatus or pendant thus be utilized for the purpose of supporting such a lamp.
The clamp mechanism 0, hereinbefore mentioned as applied to the tubes A and B, consists of the clamp-lever a, with its elevator or operative rod 1 and spring H connected with it and the head F, all being as represented, such being claimed by me in the first claim of my said Patent No. 142,107, and there, as in my present application, shown as provided with a check, L, which, with the clamping devices, constitutes the subject of the second claim of my said patent.
I herein make no claim in a chandelier-en tension to the tube A and its clamp (3, combined with and to slide on a support-rod, G; nor do I claim a tube and rod arranged and combined with burner-reservoir and provided with a friction apparatus, as shown in the United States Patent No. 64,719, dated May 14, 1867, as I employ, with the rod and tube to slide thereon, an additional tube, and a friction'and holding apparatus to slide on the first-named tube, and to support the lamp or Y burners, such not being found in the said patented apparatus.
What I claim as my present invention isl. The lamppendant or chandelienextension, substantially as described, composed of the rod G, the tube B, head F, clamp-screw E, the tube A, and the clamp-lever a, spring H, head F, elevator I (with or without the check L,) all arranged and combined essentially as specified.
2. The coupling screw-tube K and the male screw I, arranged together and combined with the suspension-rod G of the lamp-pendant, substantially as set forth. 7
LIVERUS HULL.
