NIRGEMANN, or HARTFORD, WASHINGTON, AssIGNoR To LIMA LocoMoTIvE woRKs, INCORPORATED, or NRW YORK, N. Y., A coRroRA'lIoNon VIRGINIA LocoMorIvE j f Application med April 21,

This invention relates to locomotives, and more particularly to locomotive lubrication, and is especially useful in, and applicable to, locomotives of the gear-drive verticalengine type, in connection with which it will, therefore, be described herein. `@ne of the primary objects of my invention is to providefor lubrication of locomotive parts, particularly the cylinders, in pro- 5"-0 portion to the operating conditions of the locomotive, i. e. to provide means whereby the rate of feed of the lubricant may be variedas operating conditions vary, it being Y. understood, that with locomotives in gene' eral, andmore particularly with those used in "certain kinds of service, of which the geared engine is a good example,` operating conditions Vvary at frequent intervals and overa wide range, so that at one moment the engineuwill be pulling hard `and at another itfwill `be drifting, the former condition denanding greater lubrication, and the latter, l v ess.

More specifically, therefore, it is an obj-ect Qf this invention to provide means under the ready control of the engineman, for directly altering the rate of feed of the lubricatorin accordance with changes in operating conditions, whereby over-lubrication while drift ing and under-lubrication while working (such as commonly results from va fixed, compromise adjustment of the lubricating de-` vice) is obviated.

` How the foregoing objects and advantages are obtained together with such others as are Vincident to my invention or will occur to those skilled in the art, will appear clearly from the following description of the invention viewed in the light of the accompanying drawings, wherein: A

Fig. 1 is a view looking forward in the cab of` a geared locomotive embodying my invention, certain partsbeing in section and other parts broken away; l Y

Fig. 2 is an enlarged elevational view of theadjusting mechanism and a common form of lubricator to which it may be applied, a portion of the casing of the latter being broken away, better to illustrate certain parts thereof; and

Referring first to Fig.` 1,it will be seen that -I`have therein illustrated, in a geared engine having the usual boiler 2,throttle` and reverse levers 3 and-14',rand cylinders 5 (the rear cylinder', only,`being shown), alubricator 6, which. maybe mountedron a shelf or bracket 7 in the cab,*-as shown, andadrive connection 8 for the lubricator, pivotally connected at 9 to an arm 10 onthe valve stem 11. `It should be understood, however,

. that the connecting or driving'rod-S may be driven fromany Vother suitable moving part of the locomotive which is 'solocated that the rod can be extended up into the cab where' Iflocate the lubricator 6.

L Thelubricator `6;(see Fig.` 2) which is not, Y

`per se, a part'of the `present invention, Vhas anoperatingiarm 12 which isjmade fastat one end to a short shaft 13 bymeansof `a bolt 14.v On the inner end of` shafty 13, in-

Vside the casing 15 of the-lubricator is an arm 16 carrying a pawl 17 which, upon up nand down swinging ofthe arm 12`fintermittently drives the ratchet wheel 18 which shaft, `:by degrees rotates the eccentric disc 20 which, in turning, moves the-embracing U-shap'ed Amember 21 up and down, thereby actuating the plungers 22, 23, to `pump-theoil (in a manner well understood in thisart) from the reservoir v24through suitable pipes .25, and 2,6, gauge 27, and pipes28', 23 to the .feed pipe 30, Vwhence it is delivered to the engine cylinders -5 or `other working parts. The pump is setin4 practice, for' acertain feed by an adjustmentof the plunger 22 through the screw 31.'- 1 'A "The ,foregoing brief description ofthe operation of a pump Vsuitablefor use in association with my invention (of which other forms or types mightV well be used) willfrnake clearer the operation of my, improvement, which as follows: y

I provide on the operating arm 12 of the pump a cross-head 32, slidable thereon, Vand said driving rod, and releasable latch means equipped with a locking orY latch devise for said member. Y l Y comprising a pin 33 adapted to be pressed In testimony whereof I have hereunto by a Vspring. 34 into engagement with adsigned my name. d.. 5 justment notches 35 on the armr 12, said pin GEORGE F. NIEGEMANN. #9

having. a convenient handle 36 for rdisengaging it fromthenotches. Attached tothe cross-head, as by a pin 87 with an enlarged headShaving a set-screw 39, is the upper endoif'the connecting rod S'eXtendinlg'up into f the cabi from the va-l'vestem '11.4 Y

It will now be seen thatby locating the 1 pump in a convenient position, as, for in-` stance, in the cab within ireach of the en-VV f v .o gineman, by providing an operating rod up Y Y o lint@ Athe cab from thecylinder Vvalvefstem or other suitabley moving part, and -equip- .v .ping the pump with a notchedfoperating arm v and: an':adjustablecross-head thereon to whichV i0 the'operating rodmis connected, lI make it' possible for the engineman to regulatethe feed of the pump lthat will in Vaccordance -with'rthe working conditions of the eng-ine,

for by moving thefcrosshead outwards on Y Y Y Y no I vv1everl2 theV effective stroke thereofffor a Y Y Y given movement of connecting' rod 8)is reduced and thepump willfeed less oil. .and by moving it inwards the' effective stroke'is Y increased and thelpump will feed'moreoil.
