FRANK RHIND, OF BROOKLYN, NEw YORK, AssIeNoR oF ONE-FOURTH OF Hts RIGHT To FREDERICK A. LEHMANN, OF WASHINGTON, D. c.
SPECIFICATION forming part of Letters Patent No. 224,226, dated. February 3, 1880. Application filed December 2, 1879.
To all whom it may concern:
Be it known that I, FRANK RHIND, ot' Brooklyn, in the county of Kings and State of New York, have invented certain newand useful Improvements in Coal-Oil Chandeliers; and I 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 bein g had to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in chandeliers; and it consists in a bent pipe which has an oil-reservoir placed upon one end and a number of" cups placed along at intervals to receive burners, the said pipe being suspended from above by means of rods, as will be more fully described hereinafter.
Figure l is a perspective of my invention. Fig. 2 is a vertical section ot` the glass top.
c represents the wick-cup of a coal-oil chandelier, or device for lighting windows `and fac tories, and which is placed upon a branch pipe or tube, c, which leads out from the bottom of the reservoir d, which works upon the barometrica-l principle. This reservoiris placed at one end ot' the supply-pipe, which runs along under all the cups. This tube c is supported from above by means of the rods or pipes g, and which hold the pipe c rigidly in place. Of course, this pipe c will be of any desired length, according to the size of the window, and will be provided with any suitable number of burners. For the sake of convenience the tube c is so bent that the end upon which the reservoir is placed will extend into the store, or up in one corner of the window, where it is not only readily reached, but is out of the way and takes up no room.
By means of a device of4 this kind windows of all kinds can be most brilliantly lightedby meansot' coal-oil, and at a far less price than by gas.
In order to prevent the oil from creeping up -over the tops of the cups, as it will do when the cups are made of metal, no matter to what height they may be made, I make the top c of each cup of glass, which is secured to the cup by any suitable wax or cement. Each one of these glass tops e has a flange, n,
projecting out from its lower edge, and on its bottom is made a shoulder or oft'set, o. By means of this flange, which projects out over the top of the cup or bowl and the shoulder, a joint is made, through which it is impossible for the oil to escape. Oil will not creep up a glass-surface by capillary attraction as it will a metal one; and when the Oil reaches this glass top it will go no farther, and hence never creep up over its top and run down upon the iioor.
In order to save the expense and time of cementing on the usual collaror female screw t', into which the burner screws, I apply the collar to the top while it is hot and soft, and, the glass catching in the threads on the outer side of the collar, the two parts will be secured together as one solid piece. This collar may be dropped in the molds, and the top pressed uponV it, or the two may be stuck together in any other manner preferred. This glass top is equally applicable to metallic lamps, which are being driven out ot' use on account of the oil rising overthe top and running down over the sides.
Where the conducting tubes, pipes, or arms are made of iron, their insides are thoroughly coated with lgum-shellac, or any other suitable compound which is not affected by the coaloil, so as to stop up all of the holes in the pipes through which the oil would leak.
The glass tops e may be made to cover the ventire top of the lamp or wick-cup, or the collar alone may be made of glass. It' preferred, any other substance having a vitreous face or coating may be substituted for the glass.
Having thus described my invention, I claim- A device for lighting shop-windows, consisting of the bent pipe c, upon which are placed the cups a and reservoir d, which pipe is suspended from above by means ofthe rods or pipes g, substantially as shown.
In testimony that I claimthe foregoing I FRANK RHIND.
