J ., a corporation of Delaware Application January 29, 1943, Serial No. 473,914 1 Claim. 1 This invention relates to lubricators and more particularly to a novel combination of a steam pressure actuated lubricator and a valve chest of a steam engine, the steam end of a recipro cating pump or like mechanism. Steam engines, steam pumps. and analogous (01. 184--55) 2 of a reciprocating pump showing a lubricator at tached thereto or combined therewith in‘ the manner forming the present invention.

These lubricators pump or like structure which has a valve chest have generally been attached to the engine or 2 attached thereto in which the steam valve pump by means of a bracket and require a pipe mechanism 3 operates for controlling the deliv to supply the actuating mechanism of the lubri ery of steam to the cylinder and consequently cator with steam at alternating high and lower 15 controlling operation of the engine or steam end pressures, this steam at alternating pressures be of the pump or analogous structures. ing available because of the reciprocating nature The steam valve gear illustrated in the draw of the steam cylinder and another pipe to supply ings is of an approved type such as shown in the steam to heat the oil in the reservoir of the lubri patents to J.

The housing 20 is provided with apass'age ‘2| which opens through a port 22 into the steam space 5 at one end of‘ the valve housing 2 and also opens into the steam space 23 at the inlet end of the cylinder l4 so as to provide actuating 4 actuating mechanism without the necessity of exteriorly located and. unsightly piping.
