Specilicatinn forming part of Letters Patent No. llqli, dated December 29, 1874; application tiled December l2, 1874.

To all whom it may concern:

Be it known that I, UHARLEs E. ROBINSON, of the city oi' Brooklyn, in the county of Kings and State otlNew York, have invented an lmproved Atomizer, oi'- which the following is a speeiiication:

My invention consists in the construction and combination ofthe liquid or oii valve and the gas or steam valve in an atomizer iu such a manner that, while the steam-valve surrounds the oil-valve, both may be adjusted independent of each. other, to regulate the quantitative proportion of the oil and steam jets, the outer valve being so ar 1anged, with respect to the valve-seat, that the oil and steam, in issuing from their respective valves, will form jets ot' the shape ot' thin, hollow cones inverted toward each other and intersecting each other, thereby insuring their thorough mixture and atomization. lt further consists in the combination ot' the valves with the ind uction-pipes, and also the adjustment for the valves, as will be hereinafter described with reference to the accompanying drawing, in which- Figure l is a longitudinal section of an atomizer constructed according to my present invention. Fig. 2 is a detail section of thc burner, taken through the line c .c oi' Fig'. l. Fi 3 is a cross-section taken through the line y 1/ ot' l. Figs. Il and 5 are end views ot' the stuffing-boxes t'or the steam and oil valves, respectively. Fig. (i is a detail longitudinal section ot' oil-valve stem and stuiiing-box. Fig. 7 is a detail section of a n'iodiiication ot` the burner. Fig. 8 is a section of the same taken through the line e c of Fig. 7.

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

A is a tube closed in one end, and there provided with the stuffing-box B for tightening around the stein oi" the steam valve, which, at or near the other end, is guided in a bridge-piece, a', formed in or attached to the tube A. O is the steam-valve, consisting ot' a tube, one end of which is turned conical outside to form the steam-valve surface proper, and also conical inside to form the seat for the oil-valve. Dis a short tube joining' by screw-threads .the tube A to the burner. ln

this tube D is provided the seat d1 for the valve U, and also a bridge-mecc, d", for guiding the elongated stem ot' the oil-valve. rllhe stem of the steam-valve O is threaded, at c, on the outside a distance from its outer end i'or the reception of a hand-nut, E, provided with a circular iiange, c', which revolves in lugs b formed on the stutiing-box B. The hand-nut L being thus held in position onto the smiling-box B, a turning' of the same on the threads ofthe valve-stem C will cause the latter to slide back or forth, as the case may be, thereby regulating the size of the steamvalve opening at d1, and consequently the quantity ot' steam required to atomize the oil. F is the oil valve and stem Working inside of the steam valve and stem C. Itis threaded at f a distance from its outer end, and regulated by the hand-nut G, having a circular flange, g', revolving in lugs or cleats, h', on the storting-box H in a manner exactly simila-r to that above described or' regulating the steam-valve U. To prevent the stem ot the oil-valve F from turning' with the nut, (whereby the necessary sliding motion would be defeated) a key, I, is fastened in the stuffing'- box H, and tits in a groove provided iu the end j" ot' the valve-stein F. The stuffing-box H is secured at the end of a T-joint, J, forming an elongation to the pipe C, to which it is united by an ordinary pipe titting,j. K is the oil-supply pipe, and L the steam-supply pipe. For heating the oil, its pipe K is carried for some distance inside ot' the steam-pi pe L until it branches oit' to the T-joint J and atomizer, the steampipe L being' secured by coupling to the tube A, and the oil-pipe K being secured as well to the pipe L as to the T-joint J', and the latter being' firmly secured to the valve-stem C. rlhis last is therefore prevented from turning with the hand-nut E, while the distance, from the atomizer to the portion ot' the steam-pipe parallel thereto, is made sutiicientl y large to allow them to spring and yield so as not to interfere with the sliding' motion ofthe valve U when being adjusted. The passage of the steam is indicated on the drawing by arrows l, and that ot the oil by arrows 2. The oil being forced in by steam-pressure from a separate steam-pipe, and the valve- Q ramene openings at F C d1 being of the shape of two hollow cones inverted toward each other, the jets of oil and steam must assume the shape corresponding, and, intersecting each other, become most thoroughly atomized and mixed before entering the burner. M is the burner, made, preferably, of the shape shown in the drawing.

In order to secure the most economical and effective combustion of the atomized oil and steam for fuel in a furnace, I construct the openings in the burner as follows: I make a line slit or cut, mf, either lengthwise, as shown in Figs. I and 2, or crosswise, as shown in Figs. 7 and 8, and not quite through the thickness of the metal in the burner M. In the bottom of the cut m I then make one or more very small holes, n. By now closing the slits partially, so that the thickness of the cut will be less than the diameter of the holes u, the gas-jets issuing through the holes a will be flattened out and spread in the slits m', leaving the burner as thin flames of intense heat.

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

l. In an atomizer, the combination of a valve-seat, d1, and the valves F C, one placed inside of the other, and both adjustable by means of the hand-nuts E G, in the manner substantially as specified.

2. The combination of the valve F, the tubular valve C, the Valve-seat, and the pipes A, L, and K, substantially as and for the purpose described. v

3. The combination of the stuffing-box H, having lugs h', with the key I, valve-stem j", and hand-nut Gr, substantially as and for the purpose described.
