LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 243,900, dated July 5, 1881, Application iled May l2, 1881. '(No model.)

To all whom it may concern:

Be it known that I, TIMOTHY HOLLAND, of Troy, in the county of Rensselaer and State of New York, have invented a new and useful Improvement, in Lubricators, of which the following is a specification.

My improvements relate to lubricators for the cylinders of steam-engines, particularly locoinotive-engines, and have for their object to obtain a constant and uniform delivery of lubricant under the varying conditions incident to the operation of' engines.

In my improved lubricator I utililize the steam-pressure for forcing the oil from the chamber and into adrop-chamber, from whence the oil passes to the pistons, and I further supplyr both cylinders of the locomotive from one oil-chamber. The steam-pressure is equalized by connections of novel arrangement, and an automatic valve prevents any evil effect from airpressure when the locomotive is ruiming without steam.

The construction and operation will be de scribed in detail with reference to tbe accompanying drawings, forming part of this specifcation, wherein- Figure 1 is a side elevation of a locomotive, showing the arrangements of the lubricator thereon. Fig. 2 is a vertical section of the lubricator. Fig. 3 is a similar section at right angles to Fig. 2. Fig. 4 is a detail section in larger size, showing the drop-valve and tube; and Fig. 5 is a detail section, showin g the air valve and chamber. v

Similar letters of reference indicate correponding parts.

A is the main chamber or vessel of the lua bricator, fitted at one side with a screw-nipple, a, by which it is to be secured to the front plate of the boiler, as illustrated in Figs. 1 and 3. At the upper side is attached a steam-pipe, b, that extends through the chamber and into a smaller chamber, a', that is formed on the bottom of chamber A. A screw-valve, c, and stufng-gland are fitted in the chamber a', so that the valve-seats 011 the end of pipe b can be used to regulate the outlet of steam. The upper end of pipe bwill be connected, as shown in Figi. 1, directly with the steam-dome by a I e p the upper side the chamber A is tted with a filling-plug, e. At opposite sides, and at the top ot' the chamber, are tubular plugs g g, for outlet of oil, which being of similar construction, the following description applies to either. ,I

On the outer end of plug g there is formed a downwardly-extending nipple, g,l1aving an aperture connecting with the main apertureof the plug and brought to a point at the lower Y end, so that the oil will drop readily therefrom.

To the nipple g is connected one end of a tube, 7L, of glass or other Inaterial, preferably transparent, and the lower end of the glass lis sustained by a hollow plug, fi, that is tapped into the side of chamber A, there being, however, no communication between the chamber and the plug t', except through tube h. From the plug t' a pipe, la, passes to the one steamchest at the engine, and a similar connection is made from the plug t' at the other side to the other steam-chest.

'The plug g is provided with a screw-valve, l, fitted for closing the outlet through nipple g. There is also titted on the side of the plug a hollow nipple, m, that connects by an aperture or port, m', with the tube h, and to this nipple m is connected one branch of a steampipe,a, from the boiler, so that steam may pass directly to tube h and pipe k, and the pressure from the steam-chest be thus equalized.

To prevent the water of condensation from interfering with the drop, the nipple g is eX tended within the drop-tube h a short distance and the end beveled to form an annular col lectin g-chamber, the bottom of which is formed by the acute angle of the nipple end that is nearly in contact with tube h. The water will thus be led down upon the sides of the tube h, instead of passing beneath the nipple to the droppoint.

It will be understood that the steam-pipe a connects both plugs gwith the boiler, and the pressure will thus be equalized in both. A cock will be fitted in the pipe a.

The screw-valves l allow regulation of the outlet of oil to the respective steam-chests and cylinder, so that the flow can be regulated according to the varying suction or pressure. I find it necessary to regulate the flow to each cylinder separately, for the reason that one cylinder will often take more oil than the other.

IOO

To facilitate a uniform supply to both cylinders from the one oil-chamber, the chamberA is tted with a vertical partition, o, which divides the space into two portions, having no communication, except at the bottom of tube b through the small chamber c. The plugs g enter at opposite sides of the partition, and the oil being thus kept separate, the ilow to either plug will not be affected by superior suction at the other.

In the pipe 7c, near the steam-chest, there is coupled a hollow valve-chamber, p, which may be simply a tube of larger size than the oilpipe. In this chamber is a loose ball-valve,q, playing between the opposite ends of the pipe lc,which are ground to form seats for the valve. Normally the valve q rests between the ends, separate from both, so that the oil can pass freely to the steam-chest; but in case the pressure at either side overbalances, the valve is carried against the end of the pipe," and thus the oil is prevented from being driven back through the tube k, or into the steani-cl1est in ajet, as the case may be. The principal object of the valve q is to prevent the interruption or variation of the supply-oil by the airpressure when the engine is ruiming without steam. In that case effects of the suction and compressing created by the movement of the piston in the cylinder are cut off by the described movements of the automatic valve;

In operation the lubricator is to be supplied with oil to about one-half or two-thirds the depth of the chamber, and water then supplied until the surface of the .oil is level with the outlets to plugs g. Steam being then admitted by pipe b, the oil will be forced into the plugs g, and will flow down through nipple g as fast as permitted by valves l to the end, from whence the oil will drop4 by gravity to the plug t'. From plugt' the oil will flow to pipe 7c and the steam-chest. The tube h being transparent, the operation can be seen and excess or lack of feed detected.

Vhile I prefer the described relative location and arrangements of the parts, I do not limit myself in those respects. The construction shown insures a uniform and separate supply of lubricant to the cylinders, and provides for the convenient regulation of the feed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In a lubrieator, tbe nipple g', extended down a short distance within tube h, and cut out to form an angular collecting-chamber for the water of condensation, as described.

2. The combi-nation, with two devices, one at each side, for conveying the oil separately to each chest, of an oil-reservoir A, having the bottom chamber, a', and a partition extending dowu into, but not quite to, the lower end of said chamber, as shown and described.

3. 'In lubricators, the combination, with an oil chamber or reservoir fitted with a steamsupply pipe, ot' two oil-conduit plugs and outflow pipes for delivery of the oil to the separate chests of a locomotive, and a steam-pipe connecting the outflow-pipes directly to the boiler, substantially as shown and described.
