FRANK RHIND, OF BROOKLYN, AND JOHN FARTHING, OF NEW YORK, N. Y.

CHANDELIER.

SPECIFICATION forming part of Letters Patent No. 233,433, dated October 19, 1880.

Application filed August 3, 1880. (No model.)

To all whom it may concern Be it known that we, FRANK RHIND, of Brooklyn, in the county of Kings and State of New York, and JOHN FARTHING, of New York, in the county and State of New York, have invented certain new and useful Improvements in Kerosene-Chandeliers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to an improvement in kerosene-chandeliers; and it consists in using a sealing medium consisting of quicksilver or some equivalent substance which will always seal the tube through which the oil flows to the wick-cup when the chandelier is tilted over, whereby the oil is prevented from filling the wick-cup and running over upon the floor.

It further consists in the combination of two chambers, which are formed in the tube that conducts the oil to the wick-cups, one of which chambers serves to hold the sealing medium, while the other chamber serves to prevent the sealing medium from running out while the chandelier is in the course of transportation.

The object of our invention is to prevent an excess of oil from running into one of the wickcups when the chandelier happens to be tilted upon one side, and thus prevent the oil from running over the top of the cup upon the floor.

The accompanying drawing represents a vertical section of our invention.

A represents the receiver, in which the reservoir containing the oil is placed in the usual manner. This receiver is made of glass,.and has a number of openings made through its bottom, which openings correspond to the num ber of burners with which the chandelier is provided. Secured to thisreceiver at each one of these openings is a light tube, B, of any de-' sired size, length, or shape, through which the oil from the reservoir is conducted to the wickcup 0. At the lowest point of this tube B is formed an enlargement or chamber, D, in which the sealin g medium E, of quicksilver, glyceriue, or any other suitable substance, is placed. The end of this tube B projects some distance into this chamber, so as to leave a space all around it for the sealing medium to settle in when the chandelier is tilted up, and thus prevent the sealing medium from running out of the chamber down into the receiver. This sealing medium will be gaged in quantity, so that the slightest tip of the chandelier will cause it to seal the lower end of the tube F, and thus prevent the passage of a single drop of oil to the wick-cup; but at the same time this medium never rises above the end of the tube B so as to stop the flow of oil into the chamber. At the top of this tube F is formed a second chamber, G, into which the lower end of the tube I, which conducts the oil up into the wick-cup projects. This chamber is formed for the purpose of allowing the sealing medium to run down into it while the chandelier is packed for transportation, and as there is ample space around the end of the tube I in this chamber for the sealing medium to settle, there is not the slightest danger of the medium escaping into the wick-cup. The upper end of this tube I projects a suitable distance above the top of the bottom of the wick-cup, so as to prevent all of the sediment and dirt which may settle in the wick-cup from running down into the tubes. By means of this projecting end all pieces of wick and dirt are also prevented from getting into the tube and clogging it up.

The wick-cupGis made of glass,ashereshown, and this cup, the two chambers, the conducting-tubes, and the receiver are all made in one solid piece, so as to have no joints through which the oil can leak. By thus making these parts all of glass not only is all leakage absolutely done away with, but the parts can be manufactured much more cheaply than when made of metal.

The great trouble with oil-chandeliers has always been a tendency to leak, and this they will generally do in spite of every precaution which can be taken to prevent it. More or less sulphuric acid always remains in the oil after its purification, and this acid attacks the solder at the joints and in a short time causes a leakage. By the use of glass the parts are all made in one single solid piece, and, as will readlly be seen, leakage is absolutely impossible. Atter these parts above described have been made they are placed in a suitable metallic casing or holder, and, after having been adjusted 111 position therein, plaster-of-paris or other suitable substance is poured into this casing so as to cover over the glass to any suitable extent, and thus not only center it in position, but prevent it from being broken.

Of course the chandelier can have any desired number of arms, and, if so desired, any other substances than glass may be used; but glass is much to be preferred for the reasons above stated.

\Ve are well aware that valves have been placed in the arms of chandeliers for the purpose of preventing the oil rising above acertain level in the wick-cups, and this we disclaim. It is perfectly evident to every one who knows any hing of kerosene that no metallic valve can ever be made which will prevent the oil from leaking through.

\Ve are aware that the bowl of a lamp has been made separate from its stand, and then the two parts secured together by cement, and this we disclaim.

Having thus described our invention, we claim- 1. In a kerosene-chandelier, a chamber, 1), 25 formed in the arm B between the wick-cup and reservoir-holder A, and provided with a sealing medium, E, which, when the chandelier is tilted to one side, closes the lower end of the tube F, substantially as shown. 0

2. In a kerosene-chandelier, the two lower chambers or enlargements of the conductingtube between the receiver and the wick-cups, and having interior continuations of the conducting-tubes, which project into them as de- 35 scribed, the chambers being provided with a suitable sealing medium for preventing an excess of oil from flowing into the wick-cup, substantially as set forth.

In testimony that we claim the foregoing we 0 have hereunto set our hands and seals this 21st day of July, 1880.
