IMPROVEMENT IN LAMPS.

The Schedule referred to in these Letters Patent and making part o! the same.

'Be it known that we, LEONARD S'rnnLINe and 'l. W. WILLSON, both of the city, county, and State of New York, have invented a new and useful Improveinent in Lamps, of which the following is a full,

clear, and exact description, reference being'had to the accompanying drawing'forming part of this specification, and which represents asectional elevation of a lamp in bracket form constructed in accordance with our invention. y

'Our invention, while applicable to variouskinds of lamps or illuminating coutriva'uces, including table lamps, chandeliers employing any number of burners, and bracket lights of different kllldS,'Wil1 here be de-' scribed as applied to a bracket designed to be used against a wall or other suitable support.

Although, like a certain kind of lamp, theflamc is supplied with oil or fluid at one side of the reservoir by means of a siphon-shaped tube, it essentially differs therefrom in the extension of the one leg of said tube through the fluid in the reservoir, and to or near the bottom of the latter, and in a suitable arrangement of an independent wick-holder or chamber, whereby the oil or fluid is supplied to the latter exclnsively by siphonic action, and i not by capillary attraction, aswhere the tube only connects with the top of the reservoir, and is not projected through the fluid therein, and whereby thebent supply-pipe or tube is ope'rative withoutthe insertion ot'a wicktherethrough, and otheradvantages are obtained.

Referring to the accompanying drawing- A represents the .oil or fluid-reservoir, carried by an upright back or frame-piece, B, to facilitate itsbeing hung against the wall or other support.

0 is a siphon-tube, the onelegof which is arranged to project through the cap or top of the reservoir, and down, through the oil or fluid, to or near the bottom of the reservoir, where, on its being suitably perfoi rated or formed at its lower end, as at a a, to estab lish communication with the fluid, it may rest, to form a support for the siphon in turning it, shoifld it be desirable to make the bracket a swinging one.

The other or outer end or leg of the siphon O is connected with a wick-holder or chamber, 1), of suitable depth and size to hold a fiat or other-shaped wick, I), and copious supply of oil or old thereto.

This chamber 1) carries a suitable burner, and is arranged so that its base cxtends'to within a short distance of the bottom of the reservoir A.

By this construction and arrangement of the parts there is no troublesome insertion of the wick within orthrough the siphon-tube, but it is or may be restricted exclusively to the independent holder D, that also forms an enlarged fluid-chamber, for the perfect saturation of the wick, while the tube 0 is 'clear to operate as a siphon, its projection beyond the top of the reservoir and through the fluid, down to or near the bottom of the reservoir, securing such action for it and insuring its retention of fluid at all times, 'as

well as a perfect siphonic action, as contradistinguished from a capillary'one, so long as the level of the fluid in the reservoir A is even with or above the bottom of the chamber D, which, being arranged as described, efi'ects, purely on a siphonic principle of action, the supply of the whole or greater portion of the fluid in the reservoir to the outside wick b, that, as before ob served, is altogether independent, so'far as its situation or arrangement is concerned, alike of the reservoir A and siphon-tube O, and which may readily be inserted or removed, .as in the case of anprdinary lamp, within or from its holder and secondary fluid-reservoir D, on taking oli the top of the latter.

By means of the back or frame-piece B, the siphonbracket or whole device, as thus constructed, may readily be hung against a wall, and its two reservoirs A and D retained in a vertical position.

In conclusion, it may be well to note, in connection with the operation of our improved lamp, whether in bracket-form or otherwise, that, when the wick'b has absorbed all the oil or fluid in the chamber D, and the oil or fluid in the reservoir A has, by the action of the siphon'G, reached a depth or level corresponding with the bottom of the chamber or wick-holder D, there will still remain in the siphon and reservoir a certain amount of fluid not accessible to the wick, since the bottom of the wick-holder D is always at a small distance above the bottom of the reservoir A. The furtherac'tion of the siphon-tube is consequently undisshown and described.
