To all whom it may concern:

Be it known that I, WILLIAM S. PATTER- SON, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented new and useful Improvements in Lubricators, of which the following is a specification.

My invention has relation to 'lubricators in which the oil is fed automatically and which depends more or less upon the jarring of the lubricator by the movement of the machinery with which it is connected to feed the oil.

The feeding device is adjustable from the outside and means are provided to indicate the quantity of oil in the cup at all times.

Simplicity has been an important object in working out this invention, and by it I am able to cast or mold in one piece the oil-cup, its top and bottom, the neck, the base, and a lateral housing for the adjusting device.

This fact minimizes the cost of manufacture and insures a very strong and compact structure.

The accompanying drawings illustrate the device, its various features being referred to by letters, similar letters denoting corresponding parts in the several views.

Figure 1 is a plan view of the top of the device with the oil-inlet closed. Fig. 2 is a similar view with the oil-inlet open. Fig. 3 is a side elevation of the invention Fig. 4 is a partially-vertical section on the line :20 9c of Fig. 1, the lubricator being mounted on a journal, which is shown fragmentarily. Fig. 5 is an elevation of an eyebolt, and Fig. 6 is a plan of the feeding-lever and a cross-section of the lugs.

The letter A designates the oil cup or reservoir. It is approximately square and is cast integrally with the neck 0, base E, lugs K, and housing I.

a is the oil-inlet opening into the cup A through the top a. This inlet is closed by a plate B, swinging on a pivot screw-bolt and nut b, which extends down through the top A spring b on this bolt 6 bears against the under side of the top a and the head I) on the bolt. By these means the plate B is held in close contact with the top of the cup A. A nib b on the under side of the plate B engages a socket a in the top a, whereby the plate is normally held in place' An oil-channel 0 extends downward from the cup A into the neck 0, having its lower end enlarged to form a chamber a, which opens downward through the base E.

L is aball-valveloosely seated in the chamber c and adapted when pressed upward to close the lower opening of the channel 0.

G is a lever loosely fulcrumed on a shaft g, which has bearings in the lugs K on the lower side of the base E. This lever G supports the ball F and moves it vertically to open and close the channel a. The lever G is provided with a finger g at a point opposite to its fulcrum, which is engaged by a loop h on the lower end of a spring H. The upper end of this sprin is attached to an adjusting-bolt 71. The middIe portion h of this bolt is angular and the bolt is longitudinally movable in the angular opening a through the housing I. The upper end of this bolt is round and threaded to engage a nut J, having a wrenchseat on its top and radial notches 7' on its lower face. These notches are engaged by teeth 'i on the upper surface of the housing I. L L are screw-eyebolts engaging from beneath holes 6 through the base E and extending into an oil-box M above the shaft or bearing N to be lubricated. The eyes of the bolts L are engaged by short bolts 0, which extend through the sides of'the oil-box. The small channels m and n conduct the oil from the box to the surface of the shaft N.

Theball F and the lever G are easily removed by unscrewing the nut J on the bolt h. Then by drawing down the spring II its loop is readily detached from the lever G and the ball drops out.

The oil-gage comprises a float P in the oilcup carrying a vertical wire p, which extends upward through a hole p in the top of the cup A. The middle part of the wire p is bent laterally and then downward outside of the cup and is terminated at a point in the same horizontal plane as the float P.

This lubricator is operated as follows: Move the plate B to one side and supply the cup A with oil. Adjust the lever G by means of the nut J on the rod h, so that the jarring to which the device will be subjected will give the lever G a very slight vertical movement. This movement raises and lowers the ball F, which opens and closes the oil-channel c and allows a limited downflow of the oil around the valve F and the lever G and on down to the part to be lubricated. If too much or too little oil is emitted, the nut J is turned to correct the difficulty and to secure the exact quantity required. The indicator announces at all times the quantity of oil in the cup A.

Having now described the invention and the manner of using it, what I claim, and desire to secure, is'

1. A lubricator whose oil-cup, neck, base, adjuster-housing and lugs on the lower side of said base are integral, an adjustable lever journaled in said lugs, an intake for the oil and an adjustable cover therefor as described.

2. A lubricator comprising an oil-cup, provided with an oil-inlet in its top, an oil-channel extending downward from said cup and opening into a chamber, a ball-valve in said chamber to close said channel, and an adjustable lever to support and vertically move said ball for the purpose specified.

3. A lubricator comprising an oil-cup pro- In testimony whereof I affix my signature I in presence of two subscribing witnesses.
