UNITED STATES PATENT OEEICEo CHARLES SCHOTT, OF NASHVILLE, TENNESSEE.

IMPROVED LU BRICATOR.

Specication forming part of Letters Patent No. 57,196, dated August14, 1866.

To all whom it may concern:

Be it known that I, CHARLES SCHOTT, ofthe city of Nashville, in the county of Davidson and State of Tennessee, have invented ce1- tain Improvements in Automatic Lubricators for Machinery; and I do hereby declare that the followin g is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side view. Fig. 2 is a vertical sectional view, showing the internal construction of the apparatus.

The object of this invention is to obtain a lubricator for supplying oil to the journals of machinery, which will be automatically op erated by the motion of the machine to which it is applied, which will furnish a steady and continuous supply of the lubricating material to the journal during the operation ot' the machine, but stop such delivery when themachine is not in use, and Which will also possess the additional advantages of being adjustable in such a way as to regulate the quantity of oil furnished to the journal in proportion to the requirements thereof, and of delivering only the clean oil, the sediment being allowed to settle beyond the reach of the internal working parts of the device.

To enable those skilled in the art to understand the construction and operation of my invention, I Will proceed to describe it with reference to the drawings.

D represents the journal-box, and A the shaft or journal rotating therein. F is the cup which contains the oil. It is placed uponthe box D, and incloses those parts of the apparatus which act directly upon the oil to feed it t0 the journal, these internal parts being operated, as will be presently explained, by the movements ot' the lever B. This lever is pivoted at s to the outside of the cup F, as shown in Fig. l, the pivot s passing through the cup and connecting the lever with the internal mechanism.

Upon the opposite or extreme end of the lever B is a weight, G, which causes the said lever to fall and rest upon the stop z' when not in contact with the arm or cam I of the shaft A. This cam I may be made of a strip of screw 'v holds these ends w to ether and' 7 7 7 also contines thereto the supplemental plate w, which thus forms a portion ofthe cam I.

By making the plate fw longer or shorter the movement ofthe lever B will be ,made greater or less, thus varying the movement ot' the internal mechanism and increasing or diminishing in proportion the amount of oil supplied to thejournal.

It now remains to explain the construction of the parts contained in the cup F and clearly shown in Fig. 2.

a is a vertical tube, placed in the center of the cup F and passing through the bottom of the same. It is open at both ends, the lower end reaching to the shaft or journal A and the upper end extending upward above the surface of the oil. One side'or edge of this upper end is made higher than the other, and is curved, as shown at n, in such a Way that the dippel's m, which elevate the oil, coming in contact with the inclined surface u, will deposit their adhering oil thereon. The dippers m are simply pendent pieces of Wire pivoted at one end to the ratchet-wheel c, near the perimeter thereof, the said wheel being placed close to the tube a at one side thereof. The ratchebwheel c receives a-n intermittent rotary motion from the pawl e, which is pivoted at o to the arm r, the said arm r being rigidly attached to the pivot s of the lever B. The lower edgeof the wheel c is immersed in the oil, through which the dippers m pass as the Wheel revolves.

The shaft or journal A heilig rotated as indicated by the arrow, the cam I strikes against the under side of the lever B and elevates the same, thus moving the pawl c back over the teeth of the ratchet-Wheel c.A The continued rotation of the cam 1v releasing the lever B, the said lever falls until it strikes upon the stop i, its falling motion pushing the pawl e forward and partially rotating the wheel c. The dippers m are thus passed in succession through the oil, and when elevated above the surface thereof the oil adhering to them collects upon their lower ends. The said lower ends strike against the curved surface n of the tube a carryingthe dippers, pawl 6,1ever B, and edm I, in relation to the journal-box, in the mauner and for the purpose herein set forth.

CHARLES SCHOTT.
