LAMP.

SPECIFICATION forming part of Letters Patent No. 247,114, dated September 13, 1881. Application filed May 5, 1881. (No model.)

To all whom t't may concern:

Be it known that I, STERNE RUSSELL, of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Lamps, of

which the following is a specification.

My improvements are especially applicable to the style of lamps known as students lamps, wherein the oil-reservoirs are isolated from the wick-tube and burner, and connected therewith by a laterallyextending supplytnbe. Some or all of the improvements are, however, applicable to other styles of lamps.

The improvements consist in a novel means 1 5 whereby the oil reservoir of a lamp may be conveniently filled, and in means whereby the wick-tube will be prevented from overflowing while the reservoir is being filled.

They also consist in a novel means for adjusting the wick of a lamp.

They also consist in a novel means for fastening an adjustable wick-tube, oil-reservoir, and appurtenances in ditferent positions upon a supporting'rod.

In the accompanying drawings, Figure l is a sectional elevation of a lamp embodying my improvements, with the chimney-gallery and the base omitted. Fig. 2 is a horizontal section taken through the oil -reservoir on the plane indicated by the dotted linear ac, Fig. 1.

Fig. 3 is a horizontal section through the oilreservoir on the plane of the dotted line 1 3 Fig. 1, looking upward. Fig. 4. is a vertical section of the wick-tube on an enlarged scale.

55 Fig. 5 is a top View. of the wick-tube ou the same scale. Fig. 6 is a view of the under side of the adjustable slide which fits the supporting-rod of the lamp and of certain ofitsappurtenances, and Fig. 7 is a top view of a catch for retaining said slide in position on the supporting-rod and of certain of its appurtenances.

, Similar letters of reference designate corresponding parts in all the figures.

A- designates the oil-reservoir of the lamp.

5 It may be made in the usual cyliudric form, as shown, and of sheet metal. Atthe upper end it is provided with a filling-chamber, A, and near the lower end it communicates with a supply-tube, B, extending laterally to and communicating with an upright wick tube, G.

The reservoir is permanently connected with the supply-tube B, and may be considered as v non-detachable" from other parts of the lamp. The supply-tube, as shown, is provided with a slide-tube, D,fittingasupporting-rod, E, which may be erected on any suitable base. The reservoir and the wick-tube are arranged on opposite sides of the supporting-rod E.

The filling-chamber A of the oil-reservoir may-be made of sheet metal, and it is fitted and supported within a flange, a, extending downwardly into the reservoir from the top, so as to be free to rotate or turn within said flange. In the upright wall of the filling-chamber A is an aperture, b, and atcorresponding elevation in the flange a is an aperture, 0. There is also in this wall of the filling-chamber an aperture, d, (shown at a slightly higher elevation,)and at a corresponding elevation in the flange a is an aperture, 6. These aper- 7o tures b c and d e are so arranged that when the filling-chamber is rotated or turned into one position the apertures b and c coincide, and the apertures d and 0 also coincide, and the former afford a passage for oil from the filling-chamber into the reservoir, while the latter at the same timeafford a passage for the escape of air from the reservoir. The apertures d and c are shown as somewhat smalleras well as higher than the apertures b and c. The bottom of the filling-chamber preferably slants downward to the lower part of the aperture b, so that all the oil introduced into the fillingchamber will flow into the reservoir. When the filling-chamber is rotated or turned in the 8 5 opposite direction theapertureb is thrown out of coincidence with the aperture 0 and the aperture d is thrown out of coincidence with the aperture e, so that all communication between the filling-chamber and the reservoir 0 is out Oh. Pins w on the filling-chamber, acting in conjunction with a lug, z, on the flange a, limit the rotation or turning of the fillingchamber. I

A designates a cap or plug fitting in an opening in the top of the filling-chamber A, and provided with pins f, which engage with notches g in the top edge of the filling-chem; ber, so that by rotating or turning the cap. the. filling-chambermaybe rotated orturned. This we cap is removed from the filling-chamber when it is desired to fill the reservoir, and oil may be introduced by means of an ordinary oilcan.

F designates a valve for controlling communication between the reservoir A and supply-tube B. As here shown, it is of globular form and adapted to fit a seat in the end of the supply-tube B and to be moved toward and from the end of said tube to close and open the same. It is arranged on the lower end of a lever, F, which is fulcrumed at h in the reservoir, and whose upper end bears on the face of a cam, G, afiixed to the fillingchamber. TheleverF may swinger vibratein a direction transverse to the length of the reservoir. This cam is rotated or turned with the fillin g-chamber, and hence constitutes arotarydevice for operating the valve F. When the fillingchamber is rotated or turned so as to cut off communication between it and the reservoir through the apertures b c and d c, this cam G withdraws the valve F from its seat in the supply-tubeB by rocking theleverF butwhen the filling-chamber is rotated or turned so as to establish communication between it and the reservoir, the cam Gr recedes and allows a spring, F acting on the lower part of the lever F, to rock the lever so that it will carry the valve F into its seat in the supply-tube. It will thus be'seen that during the filling of thereservoir communication between the reservoir and the supply-tube is cut off,but that communication between them is afforded at allother times. If the fillin g-chamber A is turned so as just to remove the apertures b (I out of line with the apertures c e, the valve 1 will still be left closed, owing to the position of the cam Gr with reference to said apertures.

It is obvious that in lieu of the particular form of cam G and the spring F which I have shown, a cam having a slotted or grooved operating face corresponding in shape to that of the face of the cam G, and receiving the upper end of the lever F within it, may be used, and that the spring F may then be dispensed with. In such case the cam will operate the'lever F and valve F in both directions, and the lever will preferably be made slightly resilient, so that it will yield to allow the cam to press the valve tightly in its seat after the valve'is carried into contact with its seat.

The wick-tube O is of cylindric form, and may be constructed in any suitable manner and of any approved material. It is shown as permanently secured to and supported by the supply-tube B. As usual, it is composed of au'inner and outer part, which are united at the bottom, leaving an annular open-topped space between them in communication with the supply-tube. In this space is contained the wick I, and also. a wick-adjusting tube, J, having a screw-threaded exterior, which, when rotated, operates on the inner surface of the wiclr'to raise or lower the wick, the outer part of the wick-tube,by its friction on the exterior of the wick,serving to prevent the latter from turning with the said wick-adjusting tube. At the upper end the wick-adjusting tube is provided with a cross-bar, t, which interlocks with notches j in the top of a tube, K, arranged inside the inner part of the wick-tube, and hence when the tube K is turned the wick-adjusting tube is turned also. The tube K is supported by means of ascrew-rin g, L, screwed into a socket on the bottom of the wick-tube, and embracing between it and the bottom of the wick-tube a flange extending from said tube K. This ring L is provided at its inner edge with a notch, 70, to allow it to pass over a pin, 1, with which the tube K is provided.

M designates a drip-cup, fitting on the lower end of the tube K and retained there by friction. At its upper edge is a notch, m, which interlocks with the pin lon the tube K. Hence by turning the drip-cup the tube K and the wick-adj usting tube J are turned, and the wick raised or lowered.

' On the supply-tube B, near the wick-tube G, I

is a regulator controlling the flow of oil to the wick-tube. It consists of ach amber, N, mounted on the supply-tube B, and having communication with it through an opening, 42. Above this opening the chamber is provided with transverse plates 0p, which have in them openings q r at remote points. Near the top of the chamber and above its said plates is a hole, 8, establishing communication between the chamber and the external atmosphere. When the oil by consumption becomes sufiiciently lowered air enters the chamber and passes or bubbles up into the reservoir and permits more oil to flow to the wick-tube; but while the oil is high in the wick-tube air is precluded from entering the reservoir, and as no oil can then flow from it the overflowing of the oil from the wick-tube is prevented.

On a tube arranged below the slide-tube D is a laterally extending hand piece, 0, by grasping which the said tube and attached parts of the lamp may be raised and lowered. In its under side is a cavity, t, in which is pivoted a lever, P, forming a catch or tooth, so that when its end which is adjacent to the supporting-rod E is impelled downward by pressing upward its other end it will be disengaged from the rod, and so that when its end which is adjacent to the supporting-rod is impelled upward it will engage with the rod and sustain the slidet-ube and attached parts of the lamp. At its outer end this lever P has a finger-piece, P, which may be conveniently manipulated, and conforms to the cavity tin the hand-piece O. The lever P and fingerpiece P are approximately parallel with the hand-piece 0. Between this finger-piece P and the hand-piece O are spiral springs a, which tend to depress the outer end of the lever P and to elevate its inner end, so as to cause it to engage with the supporting-rod. Hence whenever the finger-piece P is not manipulated the lever P is in engagementw-ith the supporting-rod, and the weight of the slidetube and attached parts of the lamp tends to hold it in firm engagement with the supporting-rod.

The spiral springs u may be attached to the finger-piece P, and the lever P may fit between and be steadied by bars 1; in the cavity t of the hand-piece O.

It is obvious that the hand piece 0 might be upon the slide-tube D, if desirable.

When the slide-tube and the tube or section of tube which is provided with the hand-piece O are made separate the slide -tube and attached parts can always be turned around to any position without manipulating the handpiece or appurtenances.

It will be seen that by my invention I produce a lamp which may be very easily filled, which aflords great convenience for the adjustment of the wick, and for the adjustment of the wick-tube and reservoir to different elevations.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a lamp, the combination, with an oilreservoir permanently connected with the supply-tube, of a filling-chamber arranged at the upper part of and connected to said reservoir, said filling-chamber having an opening at the top and being adapted to be rotated, while the reservoir remains stationary, to establish or cut off communication between it and said reservoir, substantially as specified.
