Letters Patent No. 111,105, dated January 24, 1871.

f IMPROVEMENT IN AUTOMATIC MI UBRICATING-SUPS.

The Schedule referred to in these Letters Patent and making part of the, same.

To whom it may concern u i Be it known that we, JAMES A. BRYAN and WIL- .LIAM Smnvmnnn, of Kent, in the county of Portage laccompanying drawing and to the letters` of reference marked thereon and being a part of this specification, in whichp Figure l is a vertical section of our improvement, and

Figure 2 is a detached viewV of the valve-eage.`

Like letters indicate like parts in each figure;

The nature of this invention relates to an improvement in devices for supplying fluid lubricants to crankpins and other revolving bearings automatically and without waste.

Theinvention consists in thc novel and peculiar arrangement, within a closed oil-cup, of a valve iu a channel leading to the bearing to be lubricated, and in a cage 0r strainer surrounding` the head of the valve, whose lift is adjusted by a temper-screw passing down through the cover of the oil-cup, the whole arranged and operating as more fully hereinafter set forth.

A representsa metallic oil-cup, closed at the top by a cap, B, threaded therein.

The cup is provided at the bottom with-a hollow stem, A', which is tapped through the strap or cover, and the box of the bearingto be lubricated.

C is an ordinary wing-valve, opening inward, and seated at the top of the hollow stern A. f

Dis a perforated cage or strainer, closed at the top,

fitting loosely over an annular elevation in thc bot-l tom of the cup, concentric with the valve. .At the greatest depression of the strainer the valve will have a slight upward plaT from its seat.

E isa threaded stein, provided at the top with a propel' head for turning it, and is screwed through the cap, its lower end stepped in a socket on the strainertop. For obvious reasons it is also with a checknut, F.

Gr is a screw in the cap, by removing which the cup ma \r be filled with a suitable lubricant. V

The cage D serves not only to keep the valve from lifting beyond the limit set by the stem ll, but also to prevent the access of any impurities in the oil to the valve-seat to interfere with the operation loi' the valve. The flow of the oil is regulated by the stem E, which is adjusted to allow the valve and strainer to lift more or less, as may be required.

The device being tapped into the upper side of :t

crank-pin, pitman-wrist, parallel-rod, or other revolving bearing, its valve is closed' during the entire circle.

described by the revolving part to which itis attached, except for an instant after passing the highest point, when the downward throw of the crank allows the centrifugal force developed. to lift the valve and thusV -permit the u regulated famount of oil to flow down through the stem to the bearing.

Having lthus described our invent-ion,

That we claim as new, and desire to secure by Letters Patent, is

`The construction and arrangement, with relation to the cup A and cap B, of the valve C, cage 0r strainer i
