JOHN O. JONES, OF TUCUMOARI, TERRITORY OF NEW MEXICO.

OIL-CONDUCTOR.

Specication of Letters Patent.

I Application filed January 10, 1906. Serial No'. 240,410.

To all whom t mrtg/concern; y

Beit known that I, JOHN O. JONES, a citizen of the United States, anda resident of Tucumcari, in the county of Quay and Territory of New Mexico, have invented a new and useful Improvement in Oil-Conductors., of

which the following is a specification.

MyA invention relates to feed devices for oil-conveying tubes, and the object is to -provide a device that will insure an even and steady flow of oil through a pipe leading from a lubricator to a chamber subject to variations in pressure--such, for instance, as the steamchest of a locomotive or engine, in which the changes of pressure are not only frequent and constant, but often very great. Experience has proved that in cases of this kind'the predominance of pressure first at one end of the conveying-tube and then atthe other causes the oil to be delivered to the slide-valve in a most irregular and unsatisfactory manner, supplying too much at one stroke and little or none at all at another, and ltherefore giving only poor results even when an excessive amount of oil is used. With my device this objectionable irregularity in the delivery of the loil is effectively overcome. thereby insuring the most satisfactory lubrication with a minimum expenditure of oil.

The invention consists in certain novel features and parts and combinations of the same, as will be fully described in the appended speciiication-and then pointed out in the claims, reference being had to the accompanying drawings, in whichv Figure 1 shows a side elevation of my improved oil-conductor in half-section and arranged in operative position in an oil-tube, said tube beingshown in section. Fig. 2 shows acentral vertical section of my device, taken online 22 of Fig. l: Fig. 3 is a plan View of the upper end of my improvement;

and Fig. 4 is a diagrammatic View of a locomotive-boiler and steam-chest, showing a luedto be introduced in a pipe-line, dividing f the same into two compartments, said body having a longitudinal passage-way therethrough and also oil and steam ports leading, respectively, from above and below said partition4 into said passage-way. I f

The letter A indicates my device as a whole, which-consists principally of the central plate l, the upper tubular extension 2,'and the lower tubular extension 3. The valve 4 at the upper end of the tubular extension 2 andthe securing-pin 5 forholding saidA valve in operative position constitute the remaining parts of my device. portions 2 and 3 are preferably formed integral with each other. tral bore 6 extends from the top of the device down to a point near the lower end l thereof.

This bore is provided with the enlarged. por-- tion 6a at its upper end, which forms a cham-y ber'for the valve 4. The oil-port holes 77 extend downwardly and inwardly at a sharp angle from the exterior of the upper tubular portion 2 into the central bore or chamber 6,y

(see Fig. 1,) while the steam-port holes 8 8,

.Fig 2, extend upwardly andinwardly at'a similar angle from the exterior of the lower tubular portion 3 into said chamber 6 andare considerably larger than the oil-port holes 7 7. 'The lower tubular extension 3 tapers downwardly from the plate l to a point near its lower end and terminates in a portion which flares first outwardly to produce a face in the formr of a truncated cone and then inwardly to a point, thereby forming the extreme lower end of the device into a cone 9. The diameter of this conical portion is less than the diameter of the upper end of the tubular extension 3.

The diminutive oil-outlet holes 10 10 are located at the lower end of the tubular portion 3 at its narrowest part or neck immediately above the truncated conical face..

These holes preferably extend downwardly and inwardly and communicate with the cen-` tral chamber 6 at its lower end.

The valve 4 is provided with a top fiange or cap portion 4a, which normally rests upon the top of the tubular portion 2 to close the upper end of the central chamber of thedevice.

annular groove 4b, lwhich provides space for the'transverse passage of the securing-pin 5, Fig. 3, which passes through suitable apertures in alinement with each other in the wall of the tubular portion 2 at one side ofthe cern...

rammed Aug. 1, 1905.

The plate l and the tubular The longitudinal cen- The valve is further provided with anter thereof, Fig. 3. This pin permits the valve to move up and down freely and to roy tate, but prevents it from being moved too far from its seat.

In use my device is placed in an oil-pipe B, at one of the joints thereof, with the central iange 1 serving as a gasket for the joint, as illustrated in Fig. l. When thus inserted, the part of the oil-pipe containing the device is practically divided thereby into two compartments, an upper and a lower, (designated by the letters B and B2.) The external diameter of the tubular portion of the device is smaller' than the internal diameter of the oilpipe B to provide a space between the two.

The operation is as follows: The oil passes down the upper compartment B' of the oilpipe till it reaches the ange l, and then through the oil-ports 7 7 into the central bore or chamber 6, and linally out through the openings l() 10 to fall in drops from the point of the cone 9. Since the valve 4 seats downward, it is apparent it will prevent oil entering the device save through the ports 7 7. When the pressure is increased in the lower compartment B2 of the oil-pipe, the air or steam in rushing upwardly toward the compartment B' will find its line of least resistance leading through the comparatively large steam-ports 8 8 into the upper part of the central bore 6 and out past the valve 4, thus leaving the oil-outlets l0 l0 and the oil-ports 7 7 practically as undisturbed Linder ordinary changes as if they were valved against the upward passage of iuid. The same is true of the oil accumulated in the lower portion 6" of the central bore or chamber 6, and also that which shall have accumulated in the chamber B, that forms the lower end of the compartment Bl between the upper tubular section 2 and the surrounding section of the oil-pipe. As Soon as equilibrium is restored in the upper portion of the pipe the valve 4 closes by gravity and the oil accumulated in the upper or external chamber B and the lower or internal chamber 6b iiows on by gravity, as usual. If the pressure be reduced in the lower compartment B2 of the oil-pipe, this will accelerate the downward How of oil, as is apparent. If the excess of pressure in the lower compartmentsuddenly becomes Very great, causing a sudden and forcible up-rush of steam, the cone 9 will deflect the steam outwardly and prevent it from directly striking the oil-outlets 10 10, and since the cone is smaller in diameter than the upper part of the lower tubular portion 3 the steam will not be deflected sufliciently to prevent it from easily striking and entering the steam-ports 8 8 without changing its general course.

My device also accelerates the downward movement of the lubricator in the oil-pipe by reason of the fact that when drops fall 4 from the point of the cone 9 they descend far more rapidly than if they were trickling down the walls of the pipe toward their final destination.

That portion of my device below the fiange l might be cut away and I would still have an effective device, or the upper portion might be removed and the same would be true if the lower part were left; but I grefer to use the device complete, as shown.

When it is desired to thoroughly clean my device, all that is necessary is to bring the upper end of the oil-tube into communication with the outer air by a cock or other suitable means and then turn a current of steam upwardly through the device.

From the foregoing it will be seen that my invention is specially desirable for high-pressure locomotives, since when they are worked at full throttle the back pressure from the steamchest is so great `that it causes the lubricator to feed imperfectly. Again, the oil that has been already fed into the feed-pipe will not flow against this excessive back pressure, even when ordinary feed devices are used, but will be checked in the pipe behind these devices.

With my device a constant flow ot' oil is secured regardless of the back pressure, the lubricator working perfectly and continuously and the oil being conducted to the valves as fast as the lubricator discharges it.

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