SPECIFICATION forming part of Letters Patent No. 578,961, dated March 16, 1897.

Application filed Septemherl 1895. Renewed January 29, 1897. Serial No. 621,222. (No model.)

To all whom it may cancel 'n:

Be it known that I, ALEXANDER T. BALLAN- TINE, of Cleveland, in the eounty of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Oiling Devices, of which the following is a specification.

My invention consists in an improved de- Vice for automatically oiling the pistons of an ammonia-pum p, hereinaftcr fully described and claimed.

Figure 1 is a side elevation, with the pump in section, of my improved device. Fig. 2 is aside elevation of the valve mechanism. Fig. 3 isa vertical central section the'eo'f on line a', Fig. 2 and Fig. 4 is a detail sectional View of portions of one of the eylinders and of the casing, the pisten being in elevation and the plane of section being at right angles to the plane of section of Fg. 1.

A represents the casing of an ammoniapump, in which B represents the cylinders, T T the pistons, E a rock-shaft actuated by a suitable motor, and D a walking beam whose ends are connected by eonnecting-rods C with pistons T, all this being the same as in my Patent No. 4:7 6,358, dated June 7, 1892.

J represents a disk loosely sleeved on shaft E and provided with a set of ratehet-teeth II, with which eng-age a pawl t', carried on an arm I, secured to the casing A to hold disk J against rotation in one direction, and another pawl h, carried on walking-beam D, to turn said disk J step by step to the right, Fig. 1. The lower part of the casingA is intended to contain oil, into which the disk J clips, and by touching each pisten T when at its lowest point leaves a little oil the-eon, all this being substantially the same as in ny pending application for patent, Serial No. 491,55S, filed November 21, 1893.

The invention of this present application relates to a device for maintaining the oillevel in casing A, the device described in my pror application being an ordinary floatvalve. Inasnueh as the pressure in casing A s comparatively small, twenty to thirty pounds, while the pressure under which the ol is delivered to said casing is ordinarily quite high, one hundred and fifty to one hundred and sixty pounds, the work imposed upon the float-valve in my former application is quite severe, and the mechanism in this application is designed to relieve the float from this Work by causing the Valve to be opened and closed positively by a moving part of the pum p, while the float simply throws the valve mechanism in and out of contact with the moving part by which it is actuated.

K represents an oil-inlet pipe leading into the bottom of casing A, the other end of which is connected with an oil-Separator, in which the oil and ammonia separate, and which is under the pressure of the compression side of the machine, which often runs to onehundred and sixt'y pounds.

Q represents a plug-valve in a casing L on 'the upper end of pipe K, the opening through said valve being represented by g.

J represents a stem connected with plug Q, adapted to Work in a slot R in casing L, so as to throw opening g in or out of communication with a small passage k, connecting with pipe K.

P represents abar through which is formed a hole m to loosely embrace sten j, and at one end bar P is connected with a lever M, which is pivoted on a pin N, Secured in the end of casing L, and said lever M is slotted, so as to be eapable of both swinging on its pivot M and of rsing and falling thereon. At the upper end lever M has a shoulder a and at the lower end a shoulder b.

d represents a float adapted to rise and fall with the varying oil-level in casing A, and connected with one end of a rod e,which passes under bar P and is pivoted at f to a lug n on casing L. I preferably curve the rod c where it passc's und er bar P in order to make it clear the casing L, but of course it can be fnlcrumed at a higher point and be straight, 'if dcsircd.

F represents a tappet on walking-beam D, so placed that when lever M is at its lowest position, as shown in Fig. l, its line of travel as said walking-beam swings will be' above the shoulder a at the top of said lever. v

G represents a tappet Secured to the end of walking-beam D and so proportioned that when lever M is at the highest point of its travel the end of said tappet G will as it is moved downward pass below the shoulder I and the lever M.

The operation of my invention is as follows: When there is no oil in casing A or too little oil, the fioat d falls, dropping lever M to the position shown in Fig. 1. As the lefthand end of walking-beam D descends, the end of tappet G strikes shoulder b, forcing it to the right, Fig. 1, and turning the plug Q, through the medium of bar P and stenj, un til the opening g therein 'egisters with the pipe K, when oil passes through the valve and flows into chamber A. As oil rises in said chamber, fioat d rises, raising bar P and lever M until finally shoulder a, comes in the line of travel of tappet F, and the notion of said walking-beata throws the npper end of lever M to the right, thus closing the valve and checking the further flow of oil. It will be seen, therefo'e, that the only work which the float d is called upon to perform is that of raising the bar P and lever M which are small light affairs, and that the opening and closing of the valve are done by the power which drives the pump. This enables me to use a small float and light red, and still to govern the oil-valve against very heavy pressure.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. In combination with a pune p-casing having moving mechanism therein, an oil-inlet ppe, a valve controlling said inlet-pipe, a movable lever connected with said valve, and governed by a float, and two tappets on the moving nechanism adapted respectively to move said lever in one direction when raised, and in the other direction when lowered, and to moving mechanism therein, two tappets on said nechanisn traveling in different paths, an oil-inlet pipe, a valve controlling said inlet-pipe, lever movably connected with said valve, shorter than the distance between the paths of said tappets, and a float operated by the oil in the pump-casing to carry said lever into the path of one tappet when the oil-level rises to a certain height, and into the path of the other tappet when the oil-level falls, whereby the valve is opened and closed by said tappets, substantially as shown and descrbed.

In combination with a vessel anchnoving mechanism theren, two tappets movng in different paths, a valve cont'rolling an inlet-pipe in said vessel,an actuating-leve' movably connected with said valve, a float and a pivoted lever connected with said float and governing the position of said valve-lever, substantially as shown and described.

4:. In combination with casing A, walkingbeam D, having tappets F and G, inlet-pipe K, valve Q, lever M movably connected with valve Q, fioat (land pivoted rod e connected to lever M, substantially as shown and described.
