ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 440,002, dated November 4, 1890.

Application tiled March 2]., 1890. Serial No. 344,705. (No model.)

.To aZZ whom it may concern:

Be it known that I, JOHN BUCKLEY, of R'Jchester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Atomizers, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The object of my invention is to produce 1o an improved atomizer to be used for atomizing fuel for hydrocarbonfurnaces, the improvements and features of novelty of the invention being hereinafter fully described, and more particularly pointed out in the r 5 claims. This atomizer is constructed soA that the condensed waterlodging therein and in the steam-pipe leading to it may be blown out without being injected into the furnace, and

vthe atomizer is provided with an improved zo form of exit or discharge for the atomized fuel. This atomizer is used, preferably, in connection with the device forcontrolling the flow of oil to injector-burners shown and described in Patent No. 402,896, of date May 7,

1889, said device being referred to by G in said patent.

Referring to the drawings, Figure l shows a front elevation of the device, parts being sectioned as on the dotted line @c in Fig. 2;

3o Fig. 2, a view of the device seen as indicated by arrow y in Fig. 1, parts being longitudinally and centrally sectioned;.and Fig. 3 a view indicated by arrow z in Fig. l.

Referring to the parts shown in the drawings, A is the atomizing device or atomizer proper; B, the oil-controlling device shown in the patent above refeined to, and C a small tube connecting the steam-space within the atomizer directly with said device B, for con* 4o trolling the ow of oil to the atomizer. The atomizer is composed of cross-pipes a b c (Z, crossing at right angles. The inflow of live steam from the steam boiler is downward through the brancho, in the passage e, and the inflow of oil from the oil-valve B is upward through the branch c along ,the passage f. The passage e turns in a horizontal direction in the branch cZand opens out at s at the delivery end of the atomizer in one direction and into the space 71, in the branch b in 5o lthe opposite direction.

t' is a stopper or valve threaded in the branch Z), having its reduced conical inner end resting against a conical seat o, to close the passage for the steam into the space 7L, the 5 5 stopper being provided with awooden handle k forconvenience of handling.

- Z is an outflow or discharge opening from the space ZL.

The branch c is connected with the steam- 6o space of the boiler by a pipe of greater or less length, and there is always, when the atomiZer has been out of use for a time, a quan# tity of water from the condensed steam in the pipe lodging in the atomizer and the lower part of the pipe j ust above the atomizer. This condensation takes place while the atomizer is out of use and, where there is no provision to prevent it, when the steam is again let into the passage to operate'. the atomizer this 7o condensed Water is of necessity all blown into the furnace. This water coming in contact with the highly-heated surfaces of the combustion-tube or parts of the boiler results sometimes in cracking the plate, and is other- 7 5 wise injurious and objectionable. To avoid this injury and danger to the parts of the boiler, I form the atomizer with the opening Z, leading out from the steam-passage e, and provide the stopper or valve t for regulating 8o said outflow-passage, as above described.

Before steam is let into the opening e to start the atomizer the stoppert'is turned back from its seat to open the passage for the water out through the opening Z. Steam being then turned on, the water is forced out at Z, and the atomizer is thus cleared of water. When the atomizer is free from water, dry steam coinmences to issue from said opening Z. During this outiiow of waterand steam to clear the 9o atomizer the'latter is inactive, as no oil can pass through the valve B until the latter is opened by steam-pressure upon t-he contained diaphragm. Vhen dry or blue steam issues from the opening Z, the stopper t' is turned 95 against its seat o to conne the steam, which then iiows through the passage ninto the tube C and opens the oil-valve, and the atomizer commences to act. The oil is drawn by the steam flowing through the passage e up through the passage f, and thrown out in an` atomized state through the opening p in the screw-cap fr.

Heretofore, on account of the atomizer becoming clogged with condensed water, slender tubes of small caliber have been used to connect the atomizer with the steam-space of the boiler, so that the steam contained in the tube would produce as little water as possible when condensed. These tribes are weak and the breakage of them amounts to a serious loss. By providing this discharge-openingZ and the stopper with which to clear the atomizer and steam-pipe of water, larger and stronger pipes may be used to connect the boiler and the atomizer, as with these provisions for the atomizer the capacity of the pipe for holding steam is a matter of no account. The outlet s of the passage e is made flaring or conical, as shown, andjithe diameter of the outlet-passage p of the screw-cap is made about equal to or larger than the largest diameter of the conical opening "8. This insures the drawing of the oil from the reservoir and its discharge into the combustiontube E. Vithout this form of passage e and opening p the oil at times will not be drawn through the passage f, and steam only will be injected into the combustion-tube. It will be seen that the opening Z is below all parts of the steam-passage e, so that the flow of water from gravity will be downward and away from said steam-passage. This tends to draw the water out of the horizontal part of the passage e. Also the portion of the steam-passage e leading out at Z is larger in diameter than the part of said steam-passage 1n CZ,wh1ch causes the water when pressed by the steam to flow out at the opening Z, rather than at the opening s. The tube 'C is designedly about the shortest connection that can be made between the steam-space within the atomizer and the interior` of the oil-valve B, and is wholly outside of the combustion-tube and furnace of the boiler, and thus not subjected to any heat greater than that of the live steam.

Ihat I claim as my invention is l. A device for atomizing oil, consisting of the parts a b c CZ joined, there being a passage e extending through the parts CZ and d and communicating with the interior of the part b, the interior of the part c communieating with the part d, and to the end thereof separated by a partition from said passage e and the interior of the part Z), a cap for the part CZ, and a valve in the part b, substantially as shown.

2. A device for atomizing oil, consisting of parts or branches a b c CZ, there being a passage e extending through the parts a and CZ, t-he interior of the part b communicating with the passage e, a valve in the part b, the interior of the Dartc communicatingwith the interior of the part d, separated by a partition from said passage e and the interior of the part h, and a cap for the part CZ, there being a communication between the interior of the part b and the outside thereof, substantially as and for the purpose specified.

In witness whereof I have hereunto set my hand, this 19th day of March, 1890, in the presence of two subscribing witnesses.
