Description: |
| Abstract:
This is an improvement in the class of engine-lubricators known as being automatic in action, in which a delivery-tube is placed within the cup or cistern, so as to receive the oil or other lubricant at the top of the cistern, the oil being supported at the proper level by the waters of condensation formed from the steam within the cistern. In oil-cups of this class a serious~ difficulty has been to render the automatic regulating-valve positive and reliable in its action and the principal cause of this difficulty has been the liability of ordinary valves to stick to their seats, or the passages to become obstructed from various causes, so as to render the steam-pressure on the exposed surface of the valve inadequate to lift the latter. It has also been customary to construct such lubricators with a cap screwing into the neck of the cup to prevent any escape of steam while in use without any means for supporting such caps while unscrewed for the purpose of refilling the cistern.
Claim:
The combination of the discharge-tube e, constructed with a countersunk or flaring upper end, forming the valve-seat at its outer edge, and the regulating-valve F, forming a sleeve, and constructed with lateral perforations at its upper end for the admission of steam to the cistern, and for the escape of the lubricant as floated up by the water of condensation. |
