IMPROVEMENT IN HEAD-LIGHTS FOR LOCOM OTIV-ES.

Specification forming partof Letters Patent No 35,486- a ed J n 1 2- To all whom it may concerrzr.v

Be it known that LSAMUEL E. CLEVELAND, of the city of Buffalo, county of Erie, and State of New York, (assignor to Jonathan Mayhew lowing is a full, clearpand. exact description thereof, reference being bad to the accompanying drawings, and the letters of reference marked thereon, in which- Figure 1 is a front elevation of my improvement; Fig. 2, avertical longitudinal section of the same; Fig. 3, a vertical section of the burner-tubes at right angles to Fig. 2; Fig. 4, a cross-section of Fig. 3 on line 1 2, and Fig. 5 a cross-section of Fig. 3 on line 3 4. 7

Letters of like name and kind refer to like parts in each of the figures.

The nature of my invention relates to several improvements in theconstruction and arrangement of a lamp for the purpose of a heat light'for locomotive-engines.

My improved lamp is so constructed as to form an annular oil and wick chamber, as represented at A, which chamber by means of the tube 13 connects with an oil-reservoir, C, so that thefehamber will be constantly supplied with oil from the reservoir. The central tube, D, (which forms the inner wall of the chamber,) is open at both ends, and, in connection with the tube E, feeds air to the interior of the wick and flame. The tube E is connected to the bottom of the annular chamber and extends downwardly, so that when the lamp is put into its place in the reflector it will pass through and below the reflector. This tube is perforated with small holes e, so as to modify the supply of air for the interior of the wick and flame. Were it not for this tube with its fine perforations, or were the tube left open at the bottom, the rush of air would be so unsteady as to greatly impair the 1ight,and at times so great as to extinguish it. The bottom of this tube should be kept closed when the lamp is burning; but it is desirable to have it open at the bottom for cleaning and trimming the lamp. For this purpose I have put in a sliding bottom, as shown at F, which may be opened and closed as desired. This annular chamber is also surrounded near its top by a perforated shield, G, to modify the supply of air for the exterior of the flame, the air for the exterior of the flame being admitted only through the perforated shield.v 'A cone-cap,H, resting upon the upper base of the shield,causes the draft through the perforated shield to strike the flame at the proper point. In order to be enabled to use a circular wick and to raise and lower it by means of a rack and pinion, I have extended the annular oilchamber downwardly by adding thereto the flat tube I, whichmakes room for the rack and pinion and enables me to run the rack up into the annular chamber for carrying the Wick up as desired.

The rack J is connected at its upper end to a narrow flat ring, K, to which ring the circular wick L is connected, so as to allow the wick to project upwardly from the ring. This ring slides over the central tube, D,and with it the circular wick. Consequently when the rack is run up or down the flat ring and wick must go with it, and will be carried perfectly true and even. When a new wick is put onto the ring'and put into place,the rack-bar will drop down into the flat tube I and gear with the pinion at. As the wick burns away,it may be run up by the rack and pinion,the rack passing into the annular chamber as far as is necessary.

A stuffing-box, N, is connected to the flat tube 1, and is made large enough to receive double glands. Thelarger or outergland,(),is of greater diameter than the pinion m, and screws into the stufling'box N, and has a leather washer, as shown at n, for packing. The inner or smaller gland, 1), screws into the larger gland, the larger gland forming its stuffing-box. The spindle Q passes through the inner gland and receives the pinion upon its inner end and the milled wheel R upon its outer end for revolving the pinion. The objectof this construction (of acompound stuffing-box having two glands) is to allow of the ready removal of the pinion with the glands, while the stuffing-box remains permanently connected to the flat tube This makes the pinion and rack conveniently accessible at all times for repair andadjustment. The stuffing for the inner gland and spindle is shown at s.

T representsthe lamp-chimney; u,drip-pan,

which is connected to the bottom of the perforated tube; V, basin for holding the drip; XV, parabolic reflector; X, standards upon which the oil-reservoir and reflectorare supported; Y,springs which are connected to the reflector for the purpose of steadying the chimney.

This construction and arrangement enable me to use kerosene and other heavy oils to great advantage.

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

1. The combination and arrangement of the perforated tube E,oiland wick chamber A,and perforated shield G, the said perforated tube being connected to the bottom of the oil-chamher for the purpose of modifying the supply of air to the interior of the wick and flame, and the perforated shield being connected to the top for the purpose of modifying thesupply of air to the exterior of the wick and flame, substantially as described.

2. A double or compound stuffing-box hav ing two glands, the smaller within the larger, constructed and operating substantially as herein set forth.

3. The extension of the oil-chamber downwardly, as represented by the flat tube I, in combination with the rack and pinion and narrow ring for raising and lowering the circular Wick, substantially as set forth.

4. The sliding bottom F, in combination with the perforated tube E, for opening and closing the mouth of the tube, substantially as set forth.
