JOHN OHESBRO, OF ONEONTA, NEW YORK.

- OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 745,152, dated November 24, 1903.

i Applicationled March 18, 1903. Serial No. 148,433. (No model.)

To all whom t may conlcern.:

Be it known that I, JOHN CHEsBRo, a citizen of the United States, and a resident of Oneonta, in the county of Otsego and State of New York, have made a certain new and useful Invention in OilCups; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which forni a part of this specification.

Figure lis a side elevation of the invention as applied. Fig. 2 is a central vertical section of the same. Fig. 3 isa detail perspective view of the cap c and its handle attachment. Fig. 4 is a top plan view of the cap c in detail. Fig. 5 is a plan View of cup with cap removed.

The invention relates to oil-feeding cups; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings the letter a designates the metallic case of the lubricator, and b the glass cup or tank which is seated therein and protected thereby. The case a is made in one piece with four openings in its side wall, so that the oil can be readily seen from any point of View in order to determine if the cup needs filling. The case is threaded around its upper end or mouth to engage the threaded cap c. The marginal portion of its mouth is radially recessed or notched at different points, this series of notches d being designed to engage the tooth e of a lever or handle f, which is connected to the cap c and extends across the same, its tooth extending downward through an opening g in said cap. The glass tank has its upper edge a little lower than the upper surface of the margin of the case to provide a seat for a gasket 7i, which in the construction shown closes the inner ends of the notches d and at the same time forms a packing for the upper end of the tank to prevent accidental escape of the oil. The lower endof the glass tank should be provided also with a gasket.

The cap is' provided with a central perforated downward-projecting lug e', having in its lower portion a threaded seat 7c, through which extends the stem Z of the regulatingvalve o, the upper end of which is provided with a boss or handle expansion m to enable the valve to be turned. Below the boss is a circular flange n, which serves as a stop to limit the upward movement of the lever.

The lower end of the stem is fashioned of acute conical form to serve as the valve which 'engages the taper seat at the opening of the exit-passage in the base of the case. Above the cone valve is the threaded portion tof the stem, and above this threaded portion is the iiuted, channeled, or ribbed portion r of said stern, which is of sufficient length to protrude through the central perforation of the cap above the upper surface thereof in any working position of the valve. In order to engage the iiuted portion of the stem to hold the valve in any adjusted position, the lever f is providedwith engaging teeth or catch projections 19 at the middle portion of its inner edge. t

As usually constructed the stop-lever f is made of spring-steel and is pivoted at its connection end to an under lug w, which engages a recess or seat s in'the marginal portion of the cap, or the lever may be pivoted to the cap. The pivot allows the lever to be turned when its tooth end is raised to elevate the tooth above the surface of the cap in order to uncover the oil-hole y and to disengage its middle catch projections from the fluted portion of the valve-stem. When so disengaged, the valve can be readily adjusted to such position as may be desirable for the rapidity of feed required and the cap may be readily screwed on or oi. When, however, the lever is down, its tooth e engages the rim-notches' of the case and its middle catch engages the uted portion of the Valve-stem in such wise that the cap is held securely from turning e parts of the engine required to be lubricated is designed to be materially diminished and IOO the engineer saved much time and worry. With propel' care in setting the valve there should be no Waste of oil, as the valve is locked positively against any increase or decrease of the feed. When the locking-lever is in engaged position, it holds the cap from turning, stops the oil-hole, and keeps the valve in adjusted position. The cup, it will be observed, is very simple in its construction and is readily taken apart for cleaning. It is designed for use not only on stationary parts, but also on those which have rapid motion, as it cannot be jarred out of adjustment.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

l. In a lubricator, the combination with the oil-cup, its engaging cap, and the adjustable feed-valveengaging said cap, ot a pivoted lever device carried by said cap, and engaging the oil-cup to lock the cap in adjusted position, and engaging the valve to look it in adjusted position, substantially as specified.

2. In a lubricator, the combination with the oil-cup, its engaging cap, and the adjustable feed-valve engaging said cap, of al horizontally and vertically movable pivoted lever de- Vice carried by said cap, and engaging the oil-cup to lock the cap in adjusted position,

and engaging the valve to lock it in adjusted position, substantially as specified.

3. In a lubricator, the marginally-notched oil-cup, the cap for the same having an ope11- ing in register with the notched margin of said cup, a threaded and iuted regulating feed-Valve engaging said cap, a locking-lever connected to said cap and having a tooth adapted to pass through the cap-opening into engagement with a notch of the oilcup margin and having a catch to engage the fiuting of said valve, substantially as specified.

4. In a lubricator, the marginally-notched oil-cup, the cap for the same having an openingin register Withrthe notched margin of said cup,aregulatingfeed-valveengagingsaid cap, and a lever device having means adapted to pass through the cap-opening into engagement with a notch of the oil-cup margin, and said device being also adapted to engage said valve to lock said valve and cap in adjusted position, substantially as specified.

In testimony whereof I affix my signature in presence ot` two WitnessesI JOHN CHESBRO.
