HYoRooARsoN STREET-LAMP.

SPECIFICATION forming part of Letters Patent No. 739,711, dated September 22, 1903.

Application filed September 20, 1901. Serial No. 75,753. (No model.)

`To all whom t may concern:

Be it known that I, CHARLES PERILLAT, a citizen of France, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Hydrocarbon Street-Lamps, of which the followingdescription, in connection with the accompanyin g drawings, is a specification, like characters on the drawings representing li ke parts.

This invention relates to a hydrocarbonburning lamp especially designed for lighting streets and like places exposed to the weather. In street-lights employing a hydrocarbon oil as the illuminant and as now commonly constructed and known to me the vaporizer is located in close proximity to the mantle within the ordinary glass globe or lantern, which is provided with suitable means by zo which access may be had tothe said vaporizer and mantle. The globe or lantern is located at the upper end of a post, which is of such height as to require the use of a ladder in order to obtain access to the vaporizer to light 2 5 the lamp with the usual torch. It frequently happens that when the door of the lantern is opened to light the lamp the mantle is shattered by the force of the wind, thereby inl creasing the cost of maintaining this system 3o of lighting.

This invention has for its object to-provide a street-lamp of the class referred to in which the lamp canbe lighted without exposing the mantle to the wind and without the use of 3 5 the ladder usually employed. For this purpose I employ a hollow post provided at its upper end with a glass globe or lantern and at its lower end with an enlarged base, which may and preferably will be made of suflicient 4o size to contain the oil-tank and vaporizer and in general all the operative parts of the lamp except the burner and mantle, which are 1ocated in the globe at the top of the post. The hollow post contains within it means for lighting the gas or vapor as it issues from the burner within the globe at the top of the post, which means is under the control of the operator from within thehollow base of said post. Provision is made within the hollow base, whereby the kerosene or other liquid hydrocarbon used may be prevented from freezing in extremely cold weatherfas will be described. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a partial section and elevation of a hydrocarbon street-lamp embodying this invention; and Fig. 2, a section on the line 2 2, Fig. l, looking toward the left.

In the embodiment of the invention herein shown a represents the globe orlantern,which is located at the upper end of the hollow post b, provided with a substantially large base c.

The post h and base c may be of metal and made in Aone or more parts, as desired, and

the globe a is-made of glass and is provided with a suitable cap d, which may be of metal.

In accordance with this invention the hollow base e contains within it the main operative parts of the lamp proper-namely, the

`oilsupply tank e,- vaporizer f, connected thereto by a pipe g, provided with a valve h; a vapor-mixing chamber i, into which the vapor is discharged fromV the vaporizer and wherein said vapor is admixed with air supplied by the air-tubesj; a heater or burner lo, l

which is connected with the mixing-chamber il by a pipe Z, provided with a shut-olf valve The vaporizer may be of anysuitable or desired construction, but preferably that shown in United States Patent No. 654,669, granted to me July 3l, 1900, it being provided with a 'needle-valve n, by which the quantity of vapor discharged into the mixing-chamber may be'regulated. The mixtureof vapor and air is conducted from the chamber t' to one or more burners o, located within the globe d, and in the present instance two burners are shown, (see Fig. 2,) which are connected to the mixing-chamber il by a pipe p, extended through the hollow post and intothe hollow base, wherein it may be provided with a shut-off or valve q. n

The burners'o ma;7 be of any suitable or usual construction and are `provided with mantles s, such as now commonly employed with this class of lamps.y As above stated, provision is made forigniting the vapor at the y I i y burners from within the hollow post, and in the present instance I have shown one means for accomplishing this result.

In the present instance the mixing-chamber 7l has connected to it a pipe 3, extended up into the globe a and provided with branches 4, which cooperate with the burners 0.

l The pipe 3 is located adjacent to and substantially iu line with the'vapor-conducting pipe p, and the branches 4 are similarly located with relation to the burners 0, as clearly shown in the drawings. The pipe 3 and its branches 4 are provided with a line of perforations 5 on the side adjacent to the pipe p andthe burners o, so that vapor issuing from the said perforations may be ignited and the iame .employed to heat the pipe p and also ignite the vapor at the burners. The pipe 3 may and preferably will be provided with a shut-off or valve 6, which is accessible from within the hollow base of the lamp-post.

To facilitate an even distribution of the vapor throughout the length of the tube or pipe 3, which latter in practice may be of considerable length, the latter may be separated into an upper and a lower chamber 'by a flange 7 on a tube 8, which latter is located within the'v lower part of the tube 3 and is of smaller diameter than the same. The tube or pipe 3 lnay be made in three parts, as represented in Fig. 1. By means of the smaller tube 8 a portion of the vapor may pass directly up into the upper chamber or portion of the tube 3.

The base c may be provided with a suitable door 9. (Shown in its open position in Fig. I.)

The perforated tube or pipe b constitutes one form of igniter, which is located within.

the hollow post and is accessible from within the base thereof.; but I do not desire to limit my invention to the particular form shown.

When the lamp is not in use, as in the daytime, the valves 6 q are closed, while the yvalves m h may be closed or open, according to circumstances, as will be described. As-` suming the valves m h closed and that it is desired to light the lamp, the operator iirst opens the valve m and heats the vaporizer by means of a hand-torch or in any other suitable or usual manner. The valve his then opened, which permits the oil contained in the tank c under pressure to flow up into the vaporizer, wherein it is vaporized, and the needle-valve n having been opened the vapor passes into the mixing-chamber t', from which it passes through the pipe Z into the heater or4 auxiliary burner la and from which it issues, being ignited by the hand-torch. As soon as the flame appears at the auxiliary burner they valve 6 is opened and vapor from the mixingchamber passes into the tube or pipe 3, from which it issues through the perforations 5 and is ignited'by the hand-torch.

When blue flame appears in the globe or lantern a, the valve q is opened and vapor from the mixing-chamber passes up through the tube p to the mantles, where it" is' ignited by the flame of the igniter. The valve 6 is then closed. It will thus be seen that the gas issuing from the burners and mantles located in the globe or lantern at the top of the post may be ignited from within said post, thus enabling the lamp to be lighted without the necessity of opening the globe or lantern, thereby avoiding the danger of shattering or breaking the fragile mantles by the wind, also dispensing with the use of the usual ladder now commonly employed and enabling the lamp to be lighted in a minimum time.

It is to be 'observed that the auxiliary burner-k heats the interior of the hollow post while the lamp isin use, as at night, and in extremely cold weather the interior of the hol- -low post may be maintained sufficiently warm Y during the day-time to prevent the oil in the l. In a lamp ofthe class described, the combination of a hollow elongated post, a globe or lantern at the upper end of the post and having lthe chamber within the globe communicating with the chamber in the post, a burner in the globe, a burner-tube extending from the chamber in the post to the burner in the globe, means for igniting the globe-burner extending from the chamber within the post to the chamber in the globe, a liquid-supplying receptacle in the post remote from the passage of communication between the post and the globe, a vaporizer, an auxiliary burner and a mixing-chamber all within the post and adapted to supply vapor to the burner within the globe, substantially as set forth.
