Description: |
| Claim:
The object of my invention is to provide a perfect lubricating-cup for oiling all kinds of stationary machinery. Experiments have demonstrated to me that a perfect lubricating arrangement must be so constructed as to allow the operator to see exactly the amount of oil flowing, to the bearing, and so arranged as to allow of a greater or less amount, at the will of the attendant, to flow steadily to said bearing. Experiments have also demonstrated to me the necessity of having the oil flowing into the pipe from reservoir to said bearing per- feetly free from any sediment or settling; and to accomplish this I take the oil from one reservoir, after being settled, into another reservoir, and then from the second reservoir I take the oil to bearing through a pipe the mouth or opening of which is near the top of second reservoir. Experience has also demonstrated that particles of dust, &c., will naturally fall through opening where operator looks to view the amount of oil flowing onto bearing. |
