IMPROVEMENT lN COAL-OIL LAMPS FOR LOCOMOTIVES.

Specification forming part of Letters Patent No. 38,001, dated March 24, 1863.

.To all whom it may concern.-

Be it known that I, PETER B'UDENBAOH, of the city, county, and State of New York, have invented a new and improved coal-oil lamp, designed as a headlight for locomotives; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a vertical section of my invention, taken in the line aa, Fig. 3; Fig. 2, a vertical section of the same, taken in the line y Fig. 3; Fig. 3, a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to obtain a lamp for burning coal-oil which may be used as a head light for locomotives and operate better than the whale-oil lamps hitherto used, and one which itis believed possesses advantages over the coal-oil lamps hitherto c011- structed for a similar purpose.

The invention consists, first, in an improved arrangement of the adjustable button for spreading the flame; second, in a horizontal perforated partition-plate placed in the wickchamber; third, in an improved draft arran gement; and, fourth, in an improved apparatus or device pertaining to the oil-fountain, as hereinafter fully set forth.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a vertical tube, to the lower end of which a perforated cylinder, B, is attached by any suitable fastening which will admit of said cyinder being readily attached to and detached from the tube A. The cylinder B may be made of wire gauze or perforated sheet metal. The latter would probably be preferable. On the upper end of the tubeA there is fitted a band, a, to which the cone or deflector O is attached. This cone or deflector may be of the usual shape or form, and it is adjusted higher or lower on the tube A, by raising or lowering the band a. By this arrangement the cone or deflector may always be adjusted so as to have a proper relative position with the flame of the lamp.

Vithin the tube A there is placed concentrically a tube, D, which is sufliciently smaller in diameter than A to admit of a requisite airspace, 11, between A and D, and within the G is a tube, which is fitted within the tube E, and is allowed to slide freely up and down within it. This tube G has a rod, H, secured vertically and centrally in it, said rod having a button, I, attached to its upper end. The button I may be of the same form as those generally used in lamps of this kind. By this arrangement it will be seen that the button is retained in proper position by the friction of the tube G in E; but the friction is not de signed to be sufficiently great to prevent the free adjustment (raising and lowering) of the button, which is accom plished by grasping the button with the fingers, or byany suitable implement or device. The tube G, in consequence of having a good bearing-surface within the tube E, prevents the casual movement of the button.

Within the wick-chamber b there is permanentl y secured a horizontal perforated partition, J, (shown in Fig. 1.) This partition may be of the same material as the perforated cylinder B.

K represents the oil-chamber, which may be described as being a flat box. This oil-chamher is made to communicate with the wickchamber 1) by means of an inclined tube, L, the lower end of which is below the perforated partition J in the wick-chamber. Within the wick-chamber there is placed what may be termed a bridge, which is constructed of a curved top plate, 0, both ends of which are in contact with the bottom of the oil chamber. This bridge is not quite equal in width to the oilchamber, and its front and back sides are formed of perforated plates d 0?. (See Figs. 1 and 2.) Within the bridge, to the under side of its top plate, 0, there is attached a perforated cylinder, M, which extends down to the bottom of the oil-chamber K and covers the orifice of the tube L. it will be seen that the oil which enters the wick-chamber I) must necessarily pass through the perforated plates d d of the bridge, and throughthe perforated cylinder M, and,then ce down through the inclined tube L into the wick-chamber below the perforated partition J and up through said partition to the wick. By this arrangement the wick is supplied uniformly with oil as the latter is consumed, the oil being prevented from rising to an undue heightin the wick-tube under the unsteady motion of the locomotive. ThiS result is due to the number and arrangement of the perforated plates or surfaces through which the oil is required to pass in order to reach the wick. The top plate, 0, of the bridge also serves to prevent the commotion or agitation of the oil above it being transmitted to the oil below it. .Ooaloil, inorder to be burned in lam psofth isclass, nust be prevented from ascending too near the flame, a contingency which frequently happens by the shaking and unsteady movement oft-he locomotive. My invention fully obviates thisdifliculty. The perforated cylinder B at the bottom of the tube A, and extending below it, admits of a uniform supply of air to the flame by adirect and uninterrupted passage or route. The ordinary lamps ofthis class have their outer tube encompassed by a perforated cylinder, which gives a sinuous passage to the draft-that is to say, a downward and thenan upward direction-and this greatly impedes the draft, rendering it fluctuating or variable.

Having thus described my invention, what I claim as new, and desire to secure by Letters Pat n v -1. Attaching the button I to a sliding tube,

G, which isfitted within the tube E, all arranged, as shown,to support the button in proper position and admit of the-readyvadj ustment of the same, as set forth.

2. The perforated cylinder B, attached to the lower end of the outer tube, A, of the lamp,

when said cylinder is made to project below- PETER BUDENBAO-H.
