LIMITED, or LoNDoN, ENGLAND, A BRITISH COMPANY j LUBRICAT'ING DEVICE Application led September 8, 1928, Serial No. 304,742, and in Great VBritain November 30, 1927.

This invention consists in improvements in or relating to lubricating devices particularly for use with steam locomotives and other steam engines and of the type consisting 5 of a chamberfor containing the lubricant and another chamber communicating there-` valves are provided to control the appara-V tus, i. e. a main steam-inlet control valve for admitting the steam to the condensing chamber, and a lubricant control valve for controlling -the flow of lubricant to the jets. These two valves have hitherto been independently operable and it frequently happens that the attendant will close the main steam valve and leave the lubricantvalve unolosed when the engine is not running, with a consequent waste of lubricant.

An object of the present invention is to overcome this diiiculty, and in lubricating apparatus of the type above described hav- `ing two independent valves, there is provided, according to the present invention, aV

single valve-operating member in combination with means coupling it with both the steam-inlet control valve and the lubricant control valve whereby both valves are actuated by said single operating member. The parts are preferably so constructed that as the operating member is moved to open the valves, the steam-inlet control valve will be opened prior to the opening of the lubricant control valve so that, by thismeans, at the commencement of operations, the requisite amount of steam may be allowed to condense in the condensing chamber before it is required to begin lubrication.

In one example of the invention, the steam-inlet control Valve comprises a main valve portion in association with a jockey valve, and means is interposed between the valve-operating member and the steam-.inlet control valve whereby the jockey valveV is first opened during the initial movement of the valve-operatingmember, and a further movement of the latter serves to open also the main steam valve portion and the lubricant control valve.

In order that the invention may be more clearly understood, one preferred construction will now be described, as an example only, with the aid of the accompanying drawings, in which Y Figure 1 is a sectional elevation taken through the steam-condensingV and lubricant-containing chambers on the line Il--l of Figure 2; i

Figure 2 is a section on .v the line 2-2 of Figure 1;

Figure 3 is a section on the Figure 1, and

Figure 4 is a plan view of the apparatus shown in Figure 1.

Like reference numerals indicate like parts in the several figures of the drawings.

The lubricating apparatus shown is of well-known construction, and, brieiiy, com.- prises a steam-condensing chamber 10 at the upper end of the apparatus, and a lubricant-containing chamber 11 beneath it. Water condensed from steam admitted to the chamber 10 passes by means of a conduit 12 past a non-return valve 13 and a manually-operable valve 14 toa passage 15 formed in a core portion 16 extending throughthe "I0 line 3- 3 of lubricant chamber 11. Y

The lubricant, which is floated on the water admitted through vthe passage 15, enters at 17 another passage 18 formed in the core portion 16 and passes from the-lower ,end of the passage 418 to a rotary plug valve 19, which is shown in the drawings in its closed' position. The valve 19 has in it .an .axial passage 20- with which communicates a 95 transverse passage 21, which can be brought into and out from register with the lower end of the conduit 18. A second transverse passage '22, which also communicates with the passage 20 and is arranged at rightangles to the passage 21, serves to connect the passage 2O with another passage 23 (Fig ure l) leading to the lubricant jets 24. It will be seen, from a consideration of the drawings, that when the valve passage 21 is closed to the passage 18, the passage 22 is also closed to the passage 23, and vice versa.

The communication between the passage 23 and each of the lubricantjets 24 is controlled lby the valve 25, and all the valves 25 can be manually adjusted. The jets 24 discharge upwardly into passages 26 and, as will be seen in Figure 3, these passages, at their upper end, are bent over horizontal- 1y and in the horizontal portion4 thej each communicate with another passage 2., into which steam is admitted in a manner to be described later. The oil is discharged lrom the horizontal portion of the passages 26 into conduits 28 leading respectively to the parts .to be lubricated.

In accordance with the present invention, steam is led from the boiler to the chamber 10 through a conduit 30, and the passage of the steam is controlled by means of a main valve 31 and a jockey valve 32 seated within an axial passage formed in the main valve portion 31. A transverse rock-shaft 33 situated below the

valve

31, 32 has secured to it a main operating handle 34 by which it can be rocked. On the rock-shaft and beneath the valve is fixed a cam 35 so shaped that the first portion of its movement will raise the jockey valve 32 from its seating in the main valve, and a further movementwill cause both the jockey valve 32 and the main valve portion 31 to be raised together. The flow of steam past the jockey valve, when that alone is raised, is relatively restricted, whereas when both the jockey valve and the main valve portion are open, a relatively unrestricted flow of steam occurs into the chamber 10.

Securedto the spindle of the valve 19 is a crank-arm 36, and interconnecting the main operating member 34 and the crank-arm 36 isa link member 37 pivotally connected to both the operating memberv and the crankarm.

TheV construction and arrangement of the parts is such that during the first movement of the main operating member 34, which will result in raising the jockey valve 32 only from its seat, the corresponding turning movement imparted through the link 37 and crank-arm 36 to the valve 19 will not turn the valve sufficiently to establish communication Y between they passage 22 in the valve and the passage 23 leading to the lubricant jets, so that although the jockey valve is opened to admit steam to the chamber 10, the flow of lubricantto the jets 24 is still shut off. When, however, the main operating member is moved further so that the cam 35 raises both the jockey valve 32 and the main valve member 31, the valve 19 opens communication between the passages 18 and 21 and the passages 22 and 23 respectively.

It will be seen that the

valve

31, 32 coni trois the admission oi steam to the passages 27, and the steam passing down these passages into the horizontal portions of the passages 26 serves to force oil into the parts to be lubricated. y Y

It will be appreciated that not only does lthe admission of steam to the apparatus en- 'In order toindicate ithe position of the,

valves, an indicator-arm 38 secured also to the rock-shaft 33 traverses a scale 39.0n which the various positions can be clearly marked. Conveniently, a spring-pressed detent 4() will snap into a recess'41 when the operating member 34 has been moved tofa position in which the jockey valve only is open. The attendant is thus given al clear indication when hehas moved the operating member to theveXtent required to open the jockey valve onlyv without-thenecessity of actually observing. the position of the indicator-arm; For the fully-open and fully-closed positions of the valves, the arm 38 can be arranged to engage iixed stops at the ends of the scale member 39. Y

Itis thought unnecessary to refer in further detail tothe construction of the lubricating apparatus as a whole, because this is of a well-known type, but it mayfbementioned that there is provided, as usual, a plug 42 closing the lubricant-filling orifice; a dis: charge-control valvev 43 for discharging the water from the chamber 11 when the lubri- Vcanthas all beenexpelled, and the usual 2.
