. UNITED STATES PATENT OFFICE.
WILLIAM G. OLIVER, OF WAUPUN, VISCONSIN.
STREET- LAM P.
SPECIFICATION forming part of Letters Patent No. 408,988, dated August 13, 1889.l
' Application filed December l2, 1888. Serial No. 293,398. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM G. OLIVER, a citizen of the United States, residing at Vaupun, Visconsin, have invented certain new and useful Improvements in Street-Lamps, of which the following is a specification.
My invention relates to that class of streetlamps which are provided with two reservoirs, one of capacity to contain sufficient oil to burn a single night and which is provided with a suitable burner, and the second of larger size, to contain a quantity of oil sufcient to refill the smaller reservoir a number of times; and myinvention consists in certain improvements in the construct-ion of such lamps, as hereinafter described, but particularly pointed out in the claims.
In the accompanying drawings, Figure l is a perspective view of the portion of the lamp to which Vmy improvements particularly relate,
the burner being omitted and an airpipe which I use in connection with the lamp being shown broken away. Fig. 2 is a central vertical section of the parts shown in Fig. l, except as to a stopper for the supply-pipe.
In the drawings, A represents the main or large reservoir, which I prefer to construct of tin and square or nearly square in its outlines. It will contain sufficient oil to burn several nights when the ordinary burner is used. This reservoir may be set inside of the lamp-case, and its form will be adapted to the sort of lamp-case with which it is connected. B is the smaller reservoir, which is made of glass or other transparent material, so as to enable the attendant to observe the operation of filling and to be certain that he has supplied a sufficient quantity of oil to furnish light through the night. Its bottom portion will be flat, or, if preferred, slightly hollowed out, as shown in Fig. 2. A collar b will be connected by a branch d with a supply-pipe D, which will be projected into the reservoir A and nearly to the bottom thereof. C represents an air-pipe which communicates with the upper side of the reservoir A. The branch d is rigidly connected with the collar b, which' latter will surround the neck b of the bowl B. E is a semicircular flange fastened to and projecting outwardly at right angles from the top of the reservoir A and adapted to receive and form a stop for the head b2 on the bottom of the bowl B. WV hen it is desired to fill the bowl B, air is forced through the flexible pipe H by applying the mouth or an air-pump thereto, which, acting on the surface of the oil in reservoir A, causes it to iiow upward through pipe D and its branch CZ and discharge into the bowl. The latter has the vent F, which vpermits the air contained in the bowl to escape while it is filling.
In assembling the part-s the pipes D and C will be secured in place, the former having the branch CZ afiXed thereto. The bowl will beput in place on top of the reservoir, the bead b2 being shoved into the curved stop E, and the collar b, having a suitable aperture to receive the end of branch d, and secured in place on the lamp by means of the cement or plaster se. The branch d will then be secured to the collar by solder, and in this way the bowl is secured to the reservoir.
Of course branch d and collar b may be screw-threaded, or it may be secured in other equivalent ways, and therefore I do not limit myinvent-ion to the precise method above described.
I claiml. In a street-lamp, the combination, with the storage-reservoir, of a transparent burnersupply bowl mounted directly thereon, a supply-pipe' projected into the reservoir and rigidly secured thereto, said pipe being extended upward and communicating with the interior of the bowl and rigidly secured thereto, and an air-pipe projected into the upper part of the reservoir, whereby to force oil into the bowl, substantially as described.
2. In a lamp, the combination, with the storage-reservoir having a iiange extended from the top wall thereof, of a transparent burner -iupply bowl adapted to seat itself against said iiange and a connecting-pipe securing said reservoirs together, substantially as described.
