ENGINE OIL CONNECTION.

Application led February 16, 1912.

To all vvwhom it 'may concern.'

Be it known that I, WILLIAM L. MORRIS, a citizen of the United States, residing at Fort lVayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Engine Oil Connections, of which the following is a specification.

The invention relates to feed connections in Isystems for supplying lubricating oil to engine bearings.

The object is to provide an improved construction and arrangement of engine lubr 1 cating oil connections, whereby the saine is rendered more eticient, and more easily maintained in a condition for normal operation.

A further object is to provide an 1mproved construction and arrangement of engine oil connections and fittings whereby the same may be easily and positively cleaned out without interfering with the running of the engine. 1

To attain these ends and to accomplish certain other new and useful'objects, the invention consists in the features of novelty hereinafter described, shown in the accompanying drawings forming a part of the specification, and nally pointed out more specifically in the appended claims.

In the said drawings, Figure 1 is a per spective view of an engine, to which my improved oiling device is shown applied. Fig. 2 is a view of a portion of an engine showing the application of the improved oiling connections to the connecting rod bearing at the crank shaft end. Figs. 3 to 5 inclusive illustrate various forms of supports by which the oil headers and mains are attached to various parts of the engine to be lubricated. Figs. 6 to 9 inclusive illustrate the details of construction of three way blow-off valve positioned at a right angle turn in the header conveniently arranged for cleaning` obstructions from the headern Figs. 10 and 11 illustrate the details of construction of the preferred form of angle valve for use with brass or copper tubing, Fig. 10 being in section; and Fig. 12 illustrates a firm of angle valve adapted for 'use with ironftubing.

ln the ycxemplification of the invention illustrated, the oil main leading from any suitable source of oil supply not shown, is indicated by the reference character 10, and lubricating oil may besupplied thereto from.

a tank by gravity or any other suitable means. Preferably the main 10 is merely a branch leading from a main supply pipe, particularly where there are a number of engines in any one immediate locality to be lubricated. The oil main 10 is'controlled by a valve indicated at 11, which may be of any desired construction, but since the main 10 lies preferably below the bed plate of the engine as shown, the bed plate being indicated by the reference character 12, a valve operating wheel as indicated at 13, secured to the upper extremity of valve stem 141-, is mounted in the stand 15 and operatively connected with valve 11, for the purpose of opening and closing it. By means of the valve 11 oil is simultaneously admitted to the. two branches 16, 17, the first of which leads to a header 1S, from which branches extend to the chief moving parts of the engine to be lubricated, except the out-board bearing which -is supplied from the branch pipe 17. The feed pipes. 16, 17 are both valve controlled, as by the hand-operated valves indicated at 19, 20 respectively. Beyond the valve 19 the feed pipe, which eX- tends upwardly to the header 18, connects with the rearward extremity of the header, the pipe of the same entering a T fitting, one branch of which is in communication with the header 1S extending over the top of the crank case. The other branch of the T fitting, which fitting is indicated by the reference character 20, may be closed with a suit able cap or plug but which is preferably removable in order that a short pipe 21 may be. connected therewith, which pipe is connected at its other end to angle valve 22, into which is adapted to be screwed or otherwise secured tle depending feed pipe 23 of a reservoir 24, the purpose of which will be hereinafter described. The header 18 is Secured to the cross head casing of the engine, indicated by the reference character 25, by suitable clips which may be formed as shown in detail in Fig. 4, and consisting of an1ember 26 provided at one end with ran eye through which the pipe 18 may be passed and being screw-threaded for attachment to a similarly threaded fastening member-"27 which is secured to the cross-head casing. 25 by screws as illustrated in Fig. 4f, or other suitable means. From the header 18 branch oil pipes extend to all the principal bearings of the engine except the out board bearing. The pipes 28, 29 extend to the eccen rio LLL)

tric valve rocker bearings, the feed pipe 30 extending to the cross-head lubricator, the feed pipes 31, 32 extending to the governor bearings, the branch feed pipe 32 leading to the lubricating device for the main crank shaft bearing, and the feed pipes 33 to 36 inclusive leading from the header 18 to the main crank shaft and eccentric bearings, the first two of said pipes feeding the main crank shaft bearing and the last two supplying the eccentric bearings.

The details of arrangement of the oil header and supply pipes will of course vary with the size and organization of the inachine to be lubricated, and the engine to which the invention is shown vapplied is merely one example of a common form of steam engine in which the main bed plate is indicated as stated by the reference character 12., the cylinder by 37, the governor by the reference character 38, the casing rovering the eccentric at 39, and the c 1ank shaft at 40. The out-board bearing support is indicated by the reference character 41, and the bearing itself at L12.` Beyond the valve 20a and connected therewith is supply pipe 413, from which lead the branch pipes 14, 415 to the out-board bearing.

It has been heretofore proposed to run lines for feeding oilup to where. they branch and to place a cross or T joint in place of an L joint, two openings in the cross being plugged and one in the T joint. Under such conditions, if the lines become blocked they could be shut oi at the engine oil stop valve, as for-example, the valve 11 or the valves 19 and 20a, as shown in the present drawings. This would enable the lines to be cleaned by running a wire through the pipes, but provides for only a partial cleaning` and much oil is usually spilled around and wasted in doing so. The present invention permits of different methods throughout. Primarily the system lconsists of a S- inch oil header, which is the size preferred and shown, although any other desired size of header may be employed. This header is provided with a stop valve as the valve 11 in the branch oil main 10, or either of the stop valves 19 or 20, which control the oil systems, fed by oil passing through each of the last mentioned valves. The header 18 beyond the stop valve 19 is provided with a valve at or near the other extremity thereof, as for example, the three-way valve indicated by the reference character 50, which reference character refers to the casing of the valve shown in detail in Figs. 6 to 9 inclusive.v The valve casing 50 is provided with the valve member 51, having three way passages therein, and being provided with the valve stem 52 and hand Wheel 53, by which the valve member 51 may be positioned as in Fig. 9 to direct oil only through the header, which is the position in which the valve normally operates,

with the branch closed. ln case it is desired to blow oil through that portion of the header between the stop valve 19 and the valve 50, the valve member 51 may be positioned as in Fig. 7. The valve member 51 may be positioned so as to direct into the crank pit, the eccentric oil guard, or as illustrated in the present embodiment of the invention, to be discharged laterally and horizontally striking the inside edge of the crank wheel 40, from which the oil will be discharged downwardly into the drippan 54 and out through the discharge duct 55 and oil conducting pipe 5G to any suitable. means for the deposit of the waste oil, as for cxample, to a filter, not h erein shown and forming no part of the present invention, but through which the oil may be passed in a well known manner and puriiied to be afterward returned to the s vstcm.

In equipping an engine with my improved oil connections, the header consisting of that portion of the pipe indicated by the reference characters 16, 18 and 43 may be either formed of iron pipe or of brass pipe. lf brass.

pipe be used it is necessary that an angle valve of the type shown in Fig. 10 be employed, in which view the header pipe is indicated by the reference character 18, and is provided on the upper side of the pipe with an opening as 18C leading into the casing of the angle valve iitting, which casing is indicated by the reference character 57. Fitting 57 is providedwith a valve member as indicated at 59 and a branch opening 58 leading to the opening 18c along the top side of the header 18 which is closed by the valve 59, having valve stem (30 and hand wheel (S1, the entrance of lthe valve stem to the chamber 58 being closed by the packing gland 62. For the branches leading from the header, as the branches indicated by the reference characrc1-S 1e, es, 29, so, 31, se, .ae-1,33 t@ :ic inelasive, and 414 and 45, it is preferred that copper be used as it'is capable of standing the bell mouthing or expanding of the ends and the making of the short bends necessary in many of the connections. ln the form of angle valve adapted for use on brass header pipes'lS, as shown in Fig. 10, also in Fig. 11, there is attached to the same a' piece of bell mouth copper tubing, which is indicated by the reference character G3, which is of the form as any of the copper tubes of the branch connection leading directly from the bearings of the header. The manner of securing the joint between the copper branch pipes and the angle valve casing is shown in detail, the bell mouth portion of the tube 63 being indicated at 63, the same impinging between the conically formed threaded nipple on the valve chamber 57 and the threaded clamping nut 611. The copper branches are secured to' the form of angle valve ada pted for use with iron pipe as illustrated 1n ico Fig. 12, in the same manner as With the angle valve shown in Fig. 10, and the same reference characters are employed to designate the parts in'that illustration. The form of valve, however, is different for to the iron header pipe, as indicated also by the reference character 18, the angle valve is secured by having the lower nipple on the casing, indicated by the reference character 65, screwed into an opening on the upper side iron pipe 18. A header pipe constructed of iron will be of sufficient thickness and strength to stand the tapping and threading. The angle valve casing is provided with a valve chamber, from which a passage 66 leads through the nipple to communicate with the opening in the header pipe 18, this opening being closed by a valve 67 similar to the valve -59 carried by stem G8 screwthreaded for adjustment in the valve casing 65 and secured in position by a packing gland, the nut of which is indicated at 69, and the hand wheel for operating the valve at 70.

Ifan engine is practically free from polished Work, painted iron headers would be most suitable. 1f lubricator cups and other parts shovi a tendency of brass finish, then the header and oil lines should be polished brass, but if all these parts are nickel plated, then. the oil headers and branchesv should be nickel plated also, the header of brass and' oil headers and the branches can be cleaned While the engine is in operation 'Without interfering With the continuous feeding of lubricant to the various bearings, which is an important consideration. lf cups at the extremities of the branch feed pipes immediately leading to the various bearings be of 'th'ge'combined pipe and hand feed type, sometimes c'alled pressure cups, as illustrated immediately over `the bearings at the eX- tremities of branch feed pipes 33 to 36 inclusive, and 14 and 45, for example, any of the branch feed pipes may be shut oif for cleaning and oil supplied through these hand-fed cups until the particular branch or branches shut off be again placed in condition for normal use. The time required for cleaning any branch Will ordinarily not exceed one filling of the cup. However, in the event that feeds be provided which do notcontain reservoirs for any considerable .quantity or supply of lubricant, then it Will he necessary to provide means for admitting oil to each series of branch feeder pipes,

which series would be shut oif with the same stop valve. I show such an arrangement in connection w1th my system, illustrated 1n Fig. 1, allof the branch feeding pipesileady the stop valvev 19 for the purpose of clean- 'i ing or repairing thepipes leading to this portion of the system, the T connection 20 may have the plug-removed therefrom and a reservoir connected to the same by means of a short sectionY of pipe 21 threaded at one extremity into an angle valve 22, and screwthreaded at one end into the T connection 20. The angle valve 22 may be in communication with a discharge spout 23 of reservoir 2li of funnel form as illustrated, and after stop valve 19 be closed oil may be admitted to the system beyond the stop valve 19 from the reservoir 24 as desired. The reservoir 24 will of course be positioned so that oil may reach all parts of the system by gravity. lVhen the system is used in connection with the form illustrated in Fig. 1, it will not be necessary to have the reservoir more than about twelve inches above the level of theA main portion of the header 18.

In Fig. 3 there is shown a form of base clip indicated bythe reference characterv 70, adapted to secure the branch feed pipes to various parts of the engine, as for eX- ample, to the main crank shaft bearing and the casing over the eccentric. It is desir'- able that the header pipe 18 be supported some distance from the engine parts and for this purpose I show two forms of specially designed supports, one of which is'described in connection with Fig. 4, and the other of which is illustrated in Fig. 5, the latter being particularly designed to support the angular branch ofthe header 18 adjacent the main crank shaft bearing and consisting of a casting 7 2 adapted to he secured by suitable screws to portions Iof the engine, and being provided with a threaded nipple adapted to receive the interior of the threaded end of a section of pipe 73 cutoff to any desiredlength, the other end of Which is likewise interiorly threaded and adapted to receive a threaded nipple on the end of an eye 74 adapted to surround the header pipe 18.

It is important that the branches leading directly from the headerto the various cups and portions to be lubricated should be supplied With unions at each end so that they may be readily detached for cleaning purposes. The header of the oil main should y k\ clean the same or to get it out of the Way of other parts that may require disconnecting while the engine is in operation.

In order to avoid the possibility of accumulation of foreign materials and ingredients that sometimes are found in lubricating materials which may clog and stop the iow, it is desirable that the oil mains and the header in particular should have smooth bottoms along as much of their length as possible, and it is to provide particularly an oil header with branches leading therefrom in which there will be no obstruction to the low ot the oil along the bottom side of the pipes that is one of the principal objects of the invention. It is also found that screw fittings and nipples placed in line, particularly in assembling the branch pipes, are not desirable, as the thi' l.ads may not be entirely uniform on the ends oi the pipe which will result in various sections of the pipes being out ot' alinement when assembled and hence disl'iguring the appearance of the system. To this end the features shown in l `igs. 10, ll and l2 are particularly desirable, since it enables me to employ a header of a continuous section ot tubing, as when brass tubing is employed with the fittings shown in Figs. 10, and 1l the fitting may be `soldered around the pipe, and when iron header tubing is employed as in Fig. 12 theI pipe maybe tapped and the fitting att-ached without cutting` the pipe. rlhus it will be seen that when fittings ot the type shown in Figs. V1() to 12 are employed for connecting the branch pipes with the header the mlmber ot' joints in the pip'eI will be, greatly reduced in each installation. In some `,ases where my improved system has been applied to engines o't the type similar to that illuS- trated herein. it has been found that the` number of joints in the pipe has been reduced to about one-.tenth that was formerly necessary where systems were installed with the ordinary threaded j forms ol littings. 'lhe necessity 'for reducing thel nun'iber ot joints as much as possible on account ot clogging of joints and leakage has already been explained and will be obvious to those skilled in they art.

ln order that the invention might be understood the details of the preferred embodiment have been shown and described, lult it is not desired to be limited to the exact details, 'tor it will bel apparent that those skilled in the art may resort to modifications and various adaptations of the invention without departing from the` purpose and lspirit thereo't'.
