SPECIFICATION forming part of Letters Patent N 0. 693,070, dated February 1 1, 1902.

To call whom, iv may concern..-

Beitknown that I, EDWIN M. ROSENBLUTH, of Philadelphia, in the State of Pennsylvania, haveinvented certain new and useful Improvements in Carriage-Lamps, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to carriage-lamps arranged to burn oil within an inclosed flamechamber provided with means to draft a supply of air from the exterior of said chamber to supply the burner.

It is the object of my invention to provide a lamp of the class specified comprising a magazine arranged to contain an ample supply of free oil and an automatic capillary regulator, whereby the supply of-oil delivered from the magazine to the burner shall be uniformly maintained as required for the maximum efficiency of the lamp regardless of the vibration to which the lamp is subjected when attached to a vehicle. I

It is a further object of myinvention to so construct and arrange such a lamp that the operator may readily ascertain the quantity of oil available in the magazine at any given instant.

My invention consists in the novel features of construction and arrangement hereinafter more definitely specified and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view of a carriage-lamp convenientlyembodyingmyinvention. Fig. 2 is a side elevation of the oil-magazine and capillary regulator of said lamp, said magazine being partially sectioned to show the relation of the regulator-thereto.

Referring to Fig. 1, A is the inclosed flamechamber, whose floor A is provided with an upwardly-projecting air-draft dome B, having an air-outlet b at its top. The bottom of said dome B opens into the air-draft chamber A within the annular flange A depending from the floor of the flame-chamber. Said flange A is provided with air-inlet apertures a so arranged as to admit the proper supply of air to the flame-chamber A through the draft-chamber A and dome- B. The prod-. nets of combustion, &c., escape from said flame-chamber through the chimney A at the top thereof. The wall A of the flame-chamber A is provided with a socket a whereby the lamp may be supported upon a suitable bracket attached to a carriage. I find it convenient to-provide the flame-chamber A with a front lens or panel of glass A and a reflector A adjoining the rear wall A which reflector is apertured at a to permit the transmission of light through the rear signal-jewel a However, the precise details of construction of the flame-chamber are not of the essence of my invention, which relates more particularly to the combination of the burner and oil-magazine with an intermediate screen, which latter is in such capillary com n1 unication with the'burner-wick and with the free oil in said magazine as to render the delivery of the oilfrorn the magazine to the burner uniform regardless of the vibration of the lamp when attached to a vehicle.

Within the draft-dome B is mounted the burner 0, whose wick-tube 0 projects through the air-outlet b at the top of said dome. The regulator-casing D is removably secured to said burner O conveniently by the screwthread (1, and said casing comprises a laterally-extending circumferential flange (1, arranged to abut against the lower edge of the flange A to limit the upward extension of the burner C with respect to the flame-chamber A. Within said casing D is concentrically mounted a cylindrical partition D, which depends through the bottom flange d of the easing, to which it is soldered, and serves to support a screen of absorbent material D conveniently formed of a tube of wicking in which is embedded a mass of absorbent material 61 such as cotton fibers or the like, through which the oil is transmitted by capillary attraction to the burner-wick C.

The oil magazine F comprises a screwthreaded neck f, fitted to the screw-threadedflange A and the internal flange F upon the magazine is provided with a gasket f, arranged. to impinge upon the bottom flange d of the casing D and to make an oil-tight joint therewith. As shown, said flange F and gasket f incline downwardly toward the center of the magazine, so as to discharge within the latter any oil which may accidentally be deposited upon them.

The parts above described being assembled as shown in Fig. 1, the oil-magazine is in capillary communication through the screen D with the wick C", so that regardless of the vibration of the lamp when attached to a vehicle the wick 0 cannot be overchargedwith oil, theoil delivered to it being comminuted by its passage through said screen. Moreover, although said wick C is in capillary communication with the screen D it is capable of adjustment independently thereof through the burner C by means of the wickshaft 0 The operator may ascertain the quantity of free oil available in the magazine at any instant by partially withdrawing the regulatorcasing D from the magazine F, as shown in Fig. 2, the depending portion of the cylinder D being obliquely terminated, as shown, to

afford the maximum view of the interior of the magazine. Such an arrangement is also advantageous in that all of the oil dripped from said cylinder D is confined to the magazine F. The rod F fixed in the magazine F, indicates the depth to which the latter should be filled with oil and being resilient is not liable to be broken.

The tube of absorbent textile material com- Y prising the screen D is conveniently fixed serves as a waterproof shelter for the matchbox F whose basal flange F extends from said standard, as shown in section in Fig. 1,

- and serves as a pedestal for the oil-magazine F when in the position shown in Fig. 2. Said match-box F being provided with a detent-spring f which normally projects through the aperture f in the standard, may

7 be released and removed from the latter at 'the will of the operator by forcing said spring inwardly and withdrawing said box by its basal flange. There being a definite position of the burner O with respect to the draft-dome B, in which the maximum efficiency of the burner is secured, I find it desirable to so constrnct the regulator-casing D that the distance between its abutment-flange dand the top of the burner C may be adjustably varied in the primary assembling of the parts in correspondence with the slight variations in relative position of the dome B and the depending flange A unavoidable in the manual assembling of the latter, and therefore I construct said casing D of two sections telescopically fitted, as shown in Fig. 1, which sections are first adjusted in proper relation Within the assembled dome B and flange A andZ subsequently seamed or soldered together at Although I have found it convenient to form the cylinder D of a cut section of perforated metal, as shown in Figs. 1 and 2, it is to be understood that it may be formed of other material. On the other hand, my improvements above described are advantageous in that whereas the free oil is screened from the burner-wick, and thus prevented from splashing through the wick-tube, only a minute quantity of the oil is suspended in the absorbent material of the screen, the bulk of the supply of oil being free and visible within the magazine, so that the precise quantity thereof available may be ascertained atany instant. Moreover, the bulk of the absorbent material-being reduced to the minimum, a corresponding increase in the oil capacity of the lampv is secured. :For instance, amagazine of the size shown when filled with saturated absorbent material would contain asup ply sufficient for approximatelyliten hours, whereas with the improved'form constituting my invention an oil-supply for 'fifty hours service of the lamp may-be carried.

I, do not desire to limit myself to the pre cise construction hereinset forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention.
