Be it known that I, J. VINCENT RENCHARD, a citizen ofthe United States, residing at Windsor, Ontario Province,I Canada, have invented an Improved Lubricator, of which the following is a specification.

The object of this device is to provide for a simple yet effective method of infusing the steam-engine with lubricants, more especially thereof', also showing its communication with pressure-pipe C' the boiler S by `means of the In the aggregate views, A is the oil-magazine; B, the steam-chest; G, the pressure-tube.

engine at Filling the device with` lubricant, its operation is as follows: The engine being at rest, valve E is opened, then valve c,when the water from boiler will force its way through the pressure-pipe G into the oil-magazine A, then out through discharge-channel c3 and c, passing valve E. When the magazine is presumably clean, the valve c is closed,likewise valve E. Cap D is then removed and magazine A filled with lubricant, after which D is replaced and valve c opened, when the deviceis ready for use. As soon as the locomotive is put in motion the valve-rod imparts motion to the connecting-arm M, lever K, and piston-valve H,

the latter being provided with drilled oil-pockets or oil-cells, and these are alternately brought under and over the inlet and discharge channels P and Q, receiving and discharging the oil that is forced into them by the superior pressure under the oil in maga-zine, which is forced upward by the hydraulic and steam pressure from the boiler through the pipe C. Remaining imbued with this pressure, the oil of its own force easily discharges into the channel Q, when the cells or oil-pockets communicate therewith. i

It will be observe-d that the number of cells which become filled with lubricant are governed by the stroke of the valve-rod O,which,

if traveling full stroke, will draw all the cells under the inlet-channel P, and if traveling short stroke will only bring underv channel P the number of cells proportioned to such travel. However, all the cells on their dischargemovement will communicate with the dischargechannel Q. As the lubricant is required by the engine the valve-rod will cause it to be delivered.

This device differs from my former application only in construction and the absence of a contractible oil-pocket.77 Although not so complete in theory, yet sufficiently practicable for all general requirements, the spirit of my invention is in this device more simply explained, and consists in placing betweenthe oil, subjected to steam and hydrostatic pressure and the various pressures and vacuum in the engine, anymechanism which may reciprocate, oscillate, revolve, or gyra-te.

IOO

being placedon the line of the discharge-tube' io and down near the steam-chest. By this plan the oil itself would exert the superior pressure against the pressure fromthe steam-chest by its own weight.

I am familiar with the patent to O. H. Pari shall, No. 126,572, iii which a disk containing a cavity which can be increased or diminished mechanically from time to time is used to convey lubricant from an inlet to a discharge channel. In his device, like others of the class, the

2o oil is subjected to the various lpressures and vacuum from the engine, not only indirectly through the cavity in the disk by induction,

` but through the pipe f f, which communicates between the eiigine-pressures and the lubricant. The tube fj' is intended principally to convey caloric to the hot-air chamber77 P,

as well as exert a downward pressure upon the lubricant, which is no greater than the variable engine-pressures, and vto which the lubricant is at all times subjected. The lubricant is dependent entirely upon its gravity,or

a weight equivalent to the height of the oil in y the oil-chamber, as shown in the drawings, to seek egress through thecavityinto the engine.

` 3,54 The lpipeff, by discharging steam into the oilchamber, creates condensation. rIhe resultant wat-er, bein g reasonably greater in volume than the oil required by the engine, seeks the bottom of the lubricant, and -is injected into the 4o engine, instead ofthe lubricant,while the latter rises in theoil-chamber and iinds egress to the engine through the pipe f f,- hence the operation of the disk and its adjustable cavity is but chiinerical. The tube f f also causes ebullition, disintegration, and oxidation of the lubricant in the receptacle, and when steam is shut off the resultant vacuum in the engine draws the lubricant out of the oil-receptacle. In his device the variable travel of the valve- 5oy rod cannotvary the discharge of the lubricant, as the single cavity in the disk can receive only a previously-regulated quantity of lubricant.

The device patented to J.w. Reed, No.

168, 671, is intended to lubricate only when the locomotive operates withoutsteam, as the lubricant therein is continually communicative with the atmosphere. My device differs entirely from the foregoing, aswell as others of similar construction, and consists in placing an intervening mechanism between the variable pressures and vacuum from the engine and I the lubricant, the latter, however, being subj ected to the steam and hydraulic pressures from the boiler, or any pressure greater than that at any time delivered to the engine. The lubricant in my device is not subjected to either the engine-pressure, vacuum7 or atmosphere v automatic regulation, while the variabletravel of the engine-valve rod or its equivalent, in combination with two or more cavities*V in the piston H, creates the mechanical regulation of the oil-discharge. The two sources combined form the auto-mechanical means.

Having described my invention, I desire to secure the following claim: A. j

rlhe method herein 'described of injecting lubricants, consisting in the employmentof the piston H, provided with oil pockets or cells, and receiving motion from' a moving member of the engine or other transmitting medium, and intervening in a channel-space, in which it operates to effect the transition of lubricant from the receiving-chaniiel Pto the dischargechannel Q, the lubricant being subjected, through the vpipe C, to the hydraulic and steam pressure from the boiler, orother pressure superior to that delivered to the engine, substantially as specified. l
