eees JAMES F. TRAVIS, 'OF YORK, N. Y. Letters Patent No. 84,975,:lated December 15, 1868.
INIPROVEMENT IN CHANDELIERS.
, -v- The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that 1, JAMES F. TRAVIS, of the city, county, and State of New York, have invented a new and useful Improrement in Extension-Chandeliers, of
.which the following is a full, clear, and exact description, reference being bad to the accompanying drawing, forming part of this specification, and in which- Figures 1 and 2 represent mostly sectional elevations at right angles to each other, and showing the extension-portion of the chandelier in raised and lowered positions. I
. Similar letters of reference indicate corresponding parts.
lates to the connection of the extension-portion with the gas-inlet above, by means of a rubber or other flexible tube; and
My invention, in such connection, consists in a novel construction and combination of the extension-portion with the chandelier, or gasolier proper, so as to present .a. neat and uniformly symmetrical appearance,in what- E is the pendent fixed tube, up or down and within.
which the sliding tube D works.
F I are the weights, connected by chains 0 c, that pass ovef pulleys d (l, with the extension-portion O, for the purposeof balancing the latter, as well known and understood. v
This, my improvement, in extension-chandeliers, re-
- While thus employing a sliding tube, D,open at its upper end, to establish the supply of gas to the extension-portion O, and working within a fixed tube, E, I
dispense with water or other packing, to preventleak- 0 age through the lower end of the fixed tube, by connecting said sliding tube with the inlet A, by a flexible tubing, G, of sufficient length to admit of the extension-portion G being-raised or lowered, as desired, without breaking the connection of the extension-portion with the gas-inlct above.
This flexible tubing may be made of any suitable material, say rubber, having acoil of wire lapped around the outside of it.
Thus, on raising the extension-portion G, as represented in fig. 2, the flexible tube or tubing G is made to coil itself within the enlarged hollow fixed portion or chamber H, and on lowering the extension-portion G to the position represented, say, in fig. 1, to uncoil or straighten itself. I
I am aware that flexible tubing has heretofore been used forcouuecting the sliding pendant with the servicepipe, and that it has also been concealed from view;
. this, therefore, I do not claim broadly; but
i What is here claimed, and desired to be secured by Letters- Patent, is- V The chandelier or gasolier, provided with a chamber,/--
H, connecting the inlet-pipe A and guide-tube E, in combination with the flexible tube G, pendant O, and
its counter-balance I, all constructed and arranged to operate substantially as shown and described, as a new article of manufacture.
