LUBRICATING SYSTEM.

Specification of Letters Patent.

Application filed November 25, 1907. Serial No. 403,621.

To all whom it may concern:

Be it known that I, WILLIAM J. SciiLAons, a citizen of the United States, residing at Chicago, in thecounty of Cool; and State of Illinois, have invented certain new and useful Improvements in Lubricating Systems, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a lubricating sys tem for locomotives and the like, and comprises as its essential parts a lubricating mechanism having a rotatingshaft, and a mechanism intermediate the lubricating mechanism and a moving part of the device to be lubricated, such as the rockerarm of an engine, and adapted to transmit rotary movement to the shaft.

In the accompanying drawings, which illustrate an embodiment of my present invention-Figure 1 is aside elevation of a locomotive equipped with my present lubricating system, the cab being broken away to show the oil pump located therein; Fig. 2 is a sectional view of one form of lubricating mechanism which may be employed;

Fig. 3 is a front elevation of the transformer with the face plate removed; Fig. 4: is a vertical sectional view of the transformer on the line 4-l of Fig. 5, and Fig. 5 is a horizontal view of the transformer on line 5-. of Fig. 3.

The locomotive shown is of the usual construction comprising among other things a boiler, cab, steam chest 7, and rocker-arm 8 of the steam-distributing mechanism.

The lubricating mechanism comprises an oil-reservoir 9, preferably mounted in the cab adjacent the engine controlling mechanism so as to be under the immediate observation and supervision of the engineer, and one or more force-feed pumps 10 of any suitable construction mounted in the reservoir and adapted to be actuated by a drive shaft 11. These lubricating pumps are shown in Fig. 2, and in general construction and mode of operation are the same as the double-acting pumps disclosed by Letters Patent of the United States No. 797,867, to I. A. Randel, dated August 22, v1905, to which reference is accordingly made for a detail description thereof, it being understood that any.nuniber of these, or other suitable, pumps may be mounted in the reservoir, with their heads suitably connected to actuating yokes 12 cooperating with cams or eccentrics13 on the drive shaft. The reservoir is provided with asuitable'supply ,opening, and the discharge pipes 14 lead reservoir into the casing of a transformer- 16 suitably mounted by its base 17 upon the engine. In the embodiment shown the transformer is outside of and in front of the cab practically in horizontal alinement with the Oil reservoir, but it obviously may be set at different positions and elevations on the engine, and for this purpose the shaft 11 may have flexible portions or sections 18 to accommodate itself to the different locations or elevations of the transformer. Obviously the shaft may be of the ordinary flexible type, but I' prefer to construct it with joints or flexible sections as stated.

The casing of the transforn'ier is provided in its side wall with a bearing.,19 for the shaft 11, which extends into the casing where it is provided with a bevel-gear 20. the bearing having a suitable stufiing-box 21. The casing is in the form of a cup or reser- ,1 voir, and comprises a head 22 suitably secured in place by screws 23. and is provided with a suitable .filler 24 in its top. The head or closure has a central bearing'for a cross-shaft 25 passing therethrough and provided with a suitable stuffing-box 2G. The shaft 25 is provided on its outer end with any suitable means as the rocker-arm 27 adapted to be moved by any moving part or element of the engine to communicate rocking or reciprocating motion to the shaft; in the present cn'ibodiment the arm 27 is connected by a link 28 to an arm 29 which .with the rocker-arm 8 forms a bell-crank lever; either or both arms 8 and 27 may be provided witha series of holes shown in dotted lines in Fig. 5 so that the connection may be adjusted to vary the throw or movement of the cross-shaft. The inner end of the shaft 25 is reduced and is seated in a bearing 30 in the opposite wall of the casing, and the shaft is held against longitudinal displace ment by a suitable pawl-lever 31 pinned thereon and bearing against the inner face of the head. The shaft 25 carries a sleeve 32 loosely mounted thereon adjacent the pawl-lever-and provided with a bevel-gear 33 meshinggwitlis thegear- 20. The-shaft is held from: longitudinal displacement by thecoiiperationzofftlidpartsijust described. The sleeve isiprovidedi with a: ratchet wheel 34 splinedthereto: between the pawl-lever 32land gean=33tliez diameter ofthe'; wheel being somewhat. less; than; the length of the pawl lever. The; rocking or reciprocating movement off sha-tlz causes the pawl-lever to .similarliy move; and its motion is transmitted to the ratchet-wheel 34: bypawls' 35- loosely mounted onpivots 36 on the pawlF-lever and extending into the plane of the ratchet wheel and engaging; the teeth thereof; The endsof the pawl leven' are somewhat extended, and. each. emensilom provided at one end a; stop-pin passing through a Bella 2a timely epenihg-imthe associated pawl,

and the other end with a to Wl'I-lltlll:

one: of a. spring: 39 the springbeing; wound upon. the associated pi t 361 :11: at'its outer end enga' the pawl to it; register with the teeth: of the wheel.

G na or more dogs 10-are provided to prevent backlash of the; ratchet wheel, and preferahly the dogs are mounted on pivots 41 on 3 the inner face of the head 22-. They may be of any suitable form, and the construction illustrated are counterparts of the pawls 35 being provided with similar openings to engage associated. stop-pins 42 and held to 35 their work by sprin 43.

The ratchet, paw lever, gear 33, pawls, dogs, and shaft 25 are all connected to the removable head 22, so that all of these parts form a unitary or self-contained structure so adapted to be assembled and disassembled wit respect to the casing or support at one and the same time by one and the same operation,'the gears 20 and 33 being placed in mesh when the inner end of the shaft is seated inits bearing 30. v The removable section or head forms a closure for the casing which preferably contains grease or lubricating oil for the operating parts, the stuflingboxes for the shafts preventing leakage, and the joint between thehead and easing being oil-tight'for this purpose.

The pawls are arranged'a half tooth apart so that one pawl operates at a time, the dogs being similarly arranged and operative, and a movement equal to one half of the pitch of the teeth'is obtained from each movement of a pawl. By this construction larger and heavier teeth may be employed on the ratchet, thus reducing the wear and doubling the resistance to'the strain.

The transformer prevents the necessity of extending a reciprocating rod from a point.

Where the power is taken to the lubricating mechanism. It also changes ,the rccipro eating motion of the rocker-arm or other parts of the steam/distributing mechanism to rotary motion of; the pump-actuating shaft, and reduces the more or" less extended throw or motion oi the, operating simple rotation OflElIGSlItIzft, By employing a separate transformer; as distinguished f'rom a structure: wherein this transformm =ti'on is accomplished? withinthev pumping mechanism itself, the latter is simplified and reduced to the lfeast possible number of parts, whereby the liability of the lubricating :mechanism becoming deranged or inoperative is reduced to a minimum, and any trouble in the transforming devices may be readily remedied without in any manner disturbiug the lubricating mechanism; by l 1 son of the unitary construction or orga-niation; or: thetranszliormer parts their assembliazgeand dis assemlhlage are easily accomp shed by the. operator; Also, the best res are obtained by having; the pumpu-rg nurcl mnism located in proximity to the engiuicanntrolliing mechanism, as the engineer is. thusenabl'ed without leaving his place to observe and regulate the rate of feed of the v pumps, each of which is independently ndjustable by a set-nut 44 which allows a greater or less lost-motion or sliding of the cross-head 45 on the pump-plunger 4.6 in a manner now Well understood in the art, and as it is desirable to economize in the size of the oil reservoir in order to occupy as liille space as possible at the engineers station, the independent transformer permits the oil reservoir to be so located while occupyinga minimum of space, and also aflords more room for oil in the reservoir. The transformation of the motion is effected at a right angle, and this is important for the reason that as the pump-actuating shaft extends longitudinally of the engine the right-angled transformer places its rocker-arm parallel with the engine and so in appropriate position to receive its movement from themoving parts of the engine. 1

\Vhile the system is illustrated in connection with a locomotive, it is of course obvious that it may be used upon other forms of engines without departing from the invention, and while I have described by invention with relation to a structure in which its variousfeatures may be embodied I do not limit myself to any such specific forms, as changes .in details and constructions fall within the scope of my invention.
