AUTOMATIC FEEDING AND WlCl =RAlSING LAMP.

EBPI-JCIPICATION forming part of Letters Patent No. 311,972, dated February 10, 1885.

Applirntion filed February 15, 1884. (No model.)

To ctZZ whom it may concern.-

Be it known that I, Ti-rorms A. Frrzsmron's, of the city and county of San Francisco. and State of California, have invented an Improvement in SelfFeeding Lamps and Clock Attachments for Feeding the Wick; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful selffeeding lamp and clock attachment for feeding the wick; and it consists in an oil-reservoir from which is suspended, by an air and an oil pipe, a peculiar cup containing the burner mechanism, to the wick of which a feeding deviceis applied, to which motion is transmitted to feed the wick by suitable gearing connected with a clock suspended from the cup, as I shall hereinafter fully describe.

The connection of the oil-reservoir, cnp,and clock, the shape of said cup, the arrangement of the wick, the construction of the feeding device,and the arrangement of gearing by which the power is transmitted from the clock, and other details, all form part of and are included in my invention, as I shall hereinafter particularly point out.

The object of my invention is to provide a lamp capable of burning a considerable time without attention by reason of the automatic feeding of the oil and wick, and therefore particularly adapted for use in churches as a sanctuary-lamp, the light of which is not intended to be extinguished. The further object is to provide in a practical manner for a combined lamp and timepiece, whereby the functions of both may be exercised and their uses enjoyed together.

Referring to the accompanying drawings, Figure l is a perspective View. Fig. 2 is a side elevation of the wick-feeding device and gear-wheels. Fig. 3 is a transverse section. Fig. 4c is a detail to be referred to.

A is the main receptacle or reservoir for V oil, and it may be of any desired shape in general outline and cross-section,and suitably ornamented. The shape which I prefer is that shown as giving the greatest interior capacity with the least outside dimensions. This is provided with a feed-aperture, a, covered by an air-tight cap, a. Into one side of this oilreservoir is let a tube, 13, the top of .which opens close under the cap a at an elevation above whatever level of oil may bein the reservoir. Into the opposite side of the reservoir is let a tube, 13, opening on the inside near its bottom. These tubes extend down wardly and open into opposite sides of the cup 0, and support said cup. The tube B is for air, and the tube 13 is for oil, the self feeding operation from the upper reservoir being thus periodical, as the end of the air-tube is exposed or covered by the receding or augmenting of the oil in the cup 0. The peculiar shape of this cup is a novel feature in this connection. Its bottom or lower portion, from a point about on aline with the air-tube, is very much narrowed, receding rapidly, as shown. Its upper portion is widened out, and it is provided with a gallery or shelf, 0, and an encircling flange, c. The object of this shape is to provide increased capacity on a line with and above the entrance of the air-tube, in order that a large supply of oil may be fed and contained at and above that level, the period of consumption of which will be considerable, while just below the line of the air-entrance, the capacity being materially reduced, the consumption will take place rapidly, and there fore will hasten the self-feeding operation by uncovering completely the air-entrance, and thus prevent the exposure of too great a portion of the wick. The shelf 0 promotes this result and acts as an overflow-bed, and the flange c is a guard to prevent the spilling of any oil by the accidental tipping of the cup.

Over the end of the oil-tube B, I have a cut-off slide, 1), though a valve of any other deseription would answer.

Standing within the cup 0 is a light frame, D, from which an arm, (1, extends upwardly, and carries the slotted burner-plate l3, through which the wick F projects. The wick is rolled on a reel, G, on one of the tubes B B, and thence extends downward over a gutter-way, g, to catch the drippings, and under a guideroller, 9, to and under a guide-roller, d, on

arm (I, and up through the burner-plate, as shown.

H is the globe fitted over the cup.

I is a clock of suitable description, the dialplate of which is in full view. This clock is suspended from the cup 0 by means of arms roo .6 from the cup, secured to the clock by means of screws 6.

In Fig. 2, J is the shaft which carries the hour-hand of the clock. Its gear J meshes with a pinion, k, on a shaft, K, above, and which also carries a pinion, 7a. This pinion meshes with a large gear, L, which meshes with a gear, M, on a shaft, m, mounted over the edge of cup 0. This shaft carriesa-pinion, N, which meshes with a gear, 0, on a shaft, 0, mounted within the cup in the top of frame D. This shaft carries afeed-pinion, P, which operates against the wick, said wick being held in contact with it by means of a roller, 1), on the other side. By this mechanism the power of the clock is transmitted up to, over, and down into the cup, and feeds the wick constantly as it is consumed. The amount of this feed is a matter of calculation, and is determined by the character and number of the intervening gears.

With the clock I have used I have found it necessary to reduce the motion by the interposition of the large gear L; but from the gear M it will be observed that the times of revolutions of each of the succeeding gears are equal, and therefore I am enabled to indicate on said gear the amount of feed which the wick has undergone. This I accomplish by a plate, Q, (shown in Figs. 2 and 4,) acting as a face for said gear M, the plate being properly graduated.

On the shaft which carries gear M is a dial.- finger, g, which moves over the graduated plate Q, for the purpose referred to.

Any proper face-plate may be used to conceal the gears, and the whole device may be suitably ornamented.

By removing the small screw which holds the frame in which the plate Q, gear M, and its shaft are contained, these parts may be removed and the lamp and clock thrown out of engagement and each perform its function separately, and, if desired, the clock itself may be removed by taking out screws 6.

I am aware that clocks and lamps have been heretofore combined in the same frame-work, each having its own function, and I do not, therefore, claim such, broadly.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a lamp having an oil-reservoir from which an air tube or passage and an oil tube or passage open out separately, a cup containing the burner devices, and into which the said air-tube and oil-tube open to accomplish the automatic feed of the oil thereto as the mouth of the air-tube is covered or uncovered by theoil, as described, said cup having a wide upper portion beginning about on a line with the mouth of the air-tube, and a lower portion rapidly contracting or narrowing where it joins the wide upper portion, substantially as and for the purpose herein described.
