IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 178,588, dated J une 13, 1876; application filed December 9, 1875.

To all whom it may concern:

Be it known that I, CHARLES C. BLISS, of Norwich, in the county of New London and State of Connecticut, have' invented an Improvenient in Lamps, of which the following is a specification:

The object of this invention is to regulate the llow of oil to a lamp-burner, So as to maintain uniformity in the height of the oil, and to allow the reservoir to be put at any convenient height above the burner, and to allow the same reservoir to be used for different burners. I accomplish this object by employing a fountain above the b'urner, and a valve in the pipe leading to the burner, which valve is closed by a uoat when the oil rises to the maximum level, and opened more or less when it descends below that level 'by the consumption thereof by the tlame. By this means the difculties in ordinary atmospheric lamp-fountains are avoided, and the supply rendered uniform and very gradual, instead ot' heilig' irregular and causing the llame to flicker.

ln the drawing, Figure 1 is a vertical section of the supply-regulator between the lampfountain and the burner, and Fig. 2 is a sectional plan above the valve.

The reservoir a is at a suitable height above the socket b, to which socket a lamp-burner of any desired character is screwed or otherwise attached, the wick ot' the lamp hanging into the oil in said socket. The socket b and reservoir a. are connected by a suitable tube, d, the portion c of which is enlarged sufliciently for receiving the float f upon the lever h, the fulcrum fi of which is located sufciently near the valve l to give the necessary leverage in opening said valve against the pressure of the Spring o. `This valve i is preferably a small disk upon a stem. The seat is ilat and circu- V lar, and the spring acts to keep the valve tightly closed except when the oil is consumed, and the level thereof descends sufficiently to cause the lloat to open the valve l and admit a' fresh suppl y otA oil.

The lloat may be annular and within the burner-socket, with the wick hanging inside such float, and the lever and valve may be connected, so that the valve will be closed by the rise of the iloat instead of a spring. rEhe supply of oil becomes automatic, and the valve will be opened only the amount that is necessary t0 maintain uniformity in the level ofthe oil as it is consumed.

The tube l may have a screw-coupling at r, to allow the parts to be disconnected for giving access to the valve for cleaning the Same.

I claim as my invention- 1. The combination, with the burner and elevated reservoir, of a float, lever, and valve, all within the tube or oil-conduits between the reservoir and burner, Substantially as set forth.

2. The valve l, stem 0, lever h, and tloatf, in combination with the valve-seat, tube d, and burnersocket b, substantially as specied. v

Signed by me this 6th day of December, A. D. 1875. y
