LUBRICAITT-NEBULIZER.

Patented Mar. 10, 1914. Serial No. 747,764.

To all whom it may concern Be it known that I, BENJAMIN F. How- Ann, a citizen of the United States, residing at Indianapolis. in the county of Marion and State ot Indiana, have invented certain new and useful Improvements in Lubricant-Nebulizers, of which the following is a specifica-tion.

The object of this invention is to mix a regulated quantity of lubricating oil with an auxiliary supply of steam, and then to discharge the mixture into a main pipe which supplies steam to the cylinder of a steam motor; and the object more particularly is to utilize the heat of the auxiliary steam supply to vaporize the oil, and then to bring the oil vapors and steam into direct contact with each other preliminary to more thoroughly nebuliziug the vapors by discharging them through a nozzle into the main steam supply pipe.

I accomplish the objects of my invention by the mechanism illustrated in the accompanying drawing, in whichk Figure 1 is an elevation and partial vertical section of a main steam pipe and a lubricator, with my invention applied in operative relation thereto. Fig. 2 is a vertical section on the line 2 2 of Fig. 1, and Fig. 3 is a horizontal section ou the line 3-3 of Fig. 1, the arrows indicating in both sections the direction of view.

Like characters of reference indicate like parts throughout the several views of the drawing.

1 is the main steam supply pipe through which live steam is conveyed in the direction of the arrows shown in said pipe to the cylinder of a steam motor (not shown).

2 is an oil container' into which a pipe 3 from a steam condenser 4l extends to near the bottom of the container 2. The condenser 4l is connected by a branch pipe 5 with the main steam supply pipe 1.

6 is a valve in pipe 5 for regulating the discharge oi steam through it.

The height of the oil in the container is shown by a glass gage 7, and on the other side of the container is a stand pipe C, preferably of glass, which communicates at its lower end with the container 2, near the bottom of the container 2. The stand pipe 8 discharges at its upper end into a horizontal pipe 9 and the pipe 8 is filled with water, glycerin, or the like, to which oil globules coming from the container 2 are floated to the level of the pipe 9, and the oil thus delivered in regulated quantities to the pipe 9 is conducted by the latter to au imderside discharge opening 10. The openlng 10 is preferably countersunk, as shown, to better collect the lubricating oil for discharge through the discharge opening 10. A drill hole in the diametrically opposite upper wall of the pipe 9, normally closed by a screw plug 11, affords means for the initial formation ot' the discharge opening 10, and also means for cleaning out the opening' should it become clogged.

Surrounding the pipe 9 between thereontainer 2 and discharge opening 10 is an annular chamber 12 (see Fig. 2), through which steam delivered from the branch pipe 5 through an auxiliary pipe 13 circulates. The annular chamber 12 discharges at its bottom into a chamber 14 extending horizontally under the pipe 9 in the direction of the main pipe 1, and separated from the pipe 9 by a common wall through which the discharge opening 10 is formed. The hot steam coming through the auxiliary pipe 13 and passing around the pipe 9 through chamber 12, and also filling and passing through the chamber 14, heats the pipe 9 and volatilizes the lubricating oil in the latter, causing it to discharge 1n a vapor through the opening 10 into the chamber 14v where it mixes with the steam in said chain ber 141-.

An extension 15 of the chamber 10 projects through the wall of the main pipe 1, an appreciable distance into the pipe 1. The chamber 14 and extension 15 are in two transversely divided parts which are united by means of a coupling 1G, and the chamber 10 also terminates in a nozzle extension 17, located within the chamber extension 15. The steam delivered under pressure to the chamber 14, and there mixed with the vaporized lubricant, as above described, is discharged with its burden oi oil through the nozzle 17 and t-he mixture .is thereby more thoroughly nebulized and blended.

The liointed construction united by coupling 16 allows the parts to be taken apart at the joints for greater convenience in manufacture and for convenience in cleaning out or changing the nozzle. In practice the nozzle 17 is made as ,a detachable part.

The auxiliary pipe 13 is in a plurality of transversely divided parts, secured by means of a coupling 18, which construction allows for the disconnection of the pipe for convenient renewal and cleanout purposes. The auxiliary pipe 13 is provided with the valve 19.

It will be observed that my invention is constructed so as to be readily applicable to use with lubricators now in common use for the purpose of rendering the latter more economical and efficient in the supply of lubricants.

While I have described my invention with more or less minuteness as regards details of construction and arrangement and as being embodied in certain precise forms, I do not desire to be limited thereto unduly or any more than is pointed out in the claims. On the contrary, I contemplate all proper changes in form, construction and arrangement, the omission of immaterial elements and the substitution of equivalents as circumstances may suggest or necessity render expedient.

I claim:

l. The combination with a main steam pipe of a mixing chamber in two transversely separable parts discharging into said pipe, an oil supply pipe discharging into said mixing chamber, means Jfor supplying oil in drops to said pipe, a steam chamber through which the oil supply pipe passes, an auxiliary pipe supplying steam to said cham- A ber, said steam chamber discharging into said mixing chamber.

one joint being `.this 6th day of February, sand nine hundred and thirteen.

2. The combination with a main steam pipe of a mixing chamber in two transversely separable parts discharging into said pipe, a nozzle in said chamber at the joint between said two parts, an oil supply pipe discharging into said mixing chamber, means for supplying oil in drops to said pipe, a steam chamber through w ich the oil supply pipe passes, an auxiliary pipe supplying steam to said chamber, said steam discharging into said mixing chamber.

3. The combination with a main steam pipe of a mixing chamber discharging into said pipe, said mixing chamber being in two transversely separable parts, a nozzle in said chamber at the ]oint between the two parts discharging toward the main steam pipe, an oil supply pipe discharging into said mixing chamber through a reduced opening in the lower wall between the oil supply pipe and mixing chamber, means for supplying oil in drops to said oil supply pipe, a steam chamber through which the oil supply pipe passes to volatilize the oil, and an auxiliary pipe supplying steam to said chamber, said steam chamber discharging into said mixing chamber.

In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana,

A. D. one thou- BENJAMIN F. HOIVARD. [Ls] Vitnesses F. IV. VOERNER, I. L. LARsoN.
