Description: |
| Abstract:
This invention concerns lubricators or oil-cups used for supplying lubricant to moving and operating parts of machinery, and relates more particularly to devices of the type known as "gravity-feed" cups. They are usually provided with a sight-feed chamber, which permits observation of the feed action, and they have a valve whereby the flow of the oil may be regulated as to the quantity passing and also entirely cut off. A stein is provided for the manipulation of the valve, the operation for the purpose being a rotary one.
Claim:
In an oil-cup, the combination of an oil-reservoir, consisting of a top, a bottom provided with an outlet-opening and an intervenient shell, a tie-post seated in the bottom and projecting above the top, a nut provided thereat to hold the parts of the cup together, a valve controlling the outlet, a rotary stem for actuating this valve, a pivotally-attached handle to manipulate this stem, a notched locking-arm adjustably mounted on the projecting end of the tie-post and above the nut thereon and adapted to engage the handle to hold the valve-stem against rotation and a o clamping-nut also fitted on the projecting end of the tie-post above the locking-arm to hold the same in its adjusted position. |
