IMPROVEMENT IN STREET-LAM PS.

Specification forming part of Letters Patent No. 162,728, dated April 27, 1875 reissue No. 6,789., dated December 7, 1875; application filed October 20, 1875.

To an whom it may concern Be it known that I, HENRY WELLINGTON,

of the city, county, and State of New York,

have invented certain Improvements in Street- Lanips, of which the following is a specification:

First, my invention consists in the combination, in a street-lamp, of a reservoir forholding the burning fluid, a glass globe resting against the reservoir, a support, against which the base of the globe rests, and a hollow supply-tube leading downwardly from readily removed for the purpose of cleaning,

without disturbing any part of the burner or flu'id s'upply tube; second, in certain improvements in connecting the burner with said reservoi r and its vaporizing'chamber and, third, in providing a hinged screen for the base of the globe, so that it may be readily opened in the operation of ligh ting-the lam p, as will hereinafter appear.

Figure 1 is an elevation of the lamp with all its attachments in proper position. Fig. 2 is a sectional view of the same; and Fig. 3 is. a section of the burner as used in said lamp.

At A is shown the top of the lamp-post, to which are attached rods B for supporting the reservoir, the inner face of which serves as a support for the globe, as represented in the drawings, and upon the said inner face of said reservoir are placed suitablemetal pieces to hold the globe in a vertical position, and

to leave room for the upward passage of air between the globe a'nd'reservoir, while its lower end rests upon a slightly-yielding base, as at E.

In" the plans hereshown the reservoir is directly attached upon the rods B, and one of said rods is hollow, as seen at F, to conveythe fluid to the burner. K is an openingfthrough which to fill the reservoir, having; a suitable plug or stopper to close the The tube F is provided with a cock, L, fbr shutting 011' the 'fluid from the burner,

.for repairs or other purposes. The lower end of the wick-tube L is secured to the cock L,

as shown, and the upper end is secured by a closely-fitting ground joint within the socket L in Fig. 3, without the' supporting wicktube inserted therein, and a chamber is also there shown at f, which extends down from the top-of said socket, and which would be along the side of the wick-tube L when it is inserted therein, and said channel serves as the vaporizing-channel or gas-generator, and leads directly to the valve at M, which controls its outlet tothe burner at N.

This means of connecting the burner with the supply'tube by a socket andground joint Without a screw or packing is very essential, and in practice is found to entirely prevent leakage, and convenient to take apart for cleaning and rewicking.

P is the valve-stem, by which the flow of of the fluid to the burner is governed. Around this stem is arranged a spring, on which rests the perforated disk or base E, said disk forming the lower support for the globe, in such a manner as to slightly yield upon the spring B. This disk is made in two parts, hinged together as shown in Fig. 2, so that one portion may be depressed by the lamp lighter pressing against a pin projecting below, and which may be forced down, as indicated by the dotted linesin Fig. 2, so that a torch may be inserted to the burner.

It will be observed that by the construction of the fluid-reservoir, the manner of supporting the globe, and the tube leading from the reservoir under the globe, that the said globe can be removed from its position for the purpose of cleaning the same without disturbing any part of the lamp, its burner, or feed supply tube, which cannot be accomplished in any of the street-lamps of this character as heretofore constructed.

I claiin. 1. The combination, in a street-lamp, of

the reservoir D, for holding the burning,

fluid, the glass globe O restingagainst the reservoir, a support, E, against which the base of the globe rests, and a hollow supplytube leading downwardly from the reservoir, andforining part of the frame, substantially as described.

2. The vaporizing-eha1nber, consisting of 4. The sp'ringR for supporting in a yielda tube L, the socket L, and the channelf iug manner the disk E and globeO, as and. communicating with the said socket and the for the purpose set forth.

burner, substantially as described. HENRY WELLINGTON.

3. The hinged perforatel base, constructed Attest: and arranged substautiallyos and 'for the TRUMAN P. DOANE,

purpose specified. BOYD "ELIOT.
