- This invention relates to improvements in force feed mechanism for-supplying :oil'to bearings. f 1"; -The primary object of the presentinven- D I tionis to provide an improved force 'feed vide a force feed oiler for railway car and lo- 1 -oiler designed particularly for use upon the r trucks of locomotives 1 and railway cars,'. the

-- power for forcing the lubricant through 5 various supply pipes being obtainedithrough 10 xthefutilization of "the relative movement be- I tween the 'car axle and the body of the" truck -vwhile the car is running,.the axle of thetruck and body thereof normally having relative -'.movement at this time."- c r Another -object of the invention is to prov, comotivetrucks so designed that-the supply of oil to the various bearings of the truck may be regulated and oil'ejected from certain g ,v-e ector mechanism 1DC6XC6SS"OIE'D the. amount which the supply lines forgthe bearings can handle may be shunted to return to the res'er 1 voir from-which it is taken. '1

v v Axstillxfurther obj ect'of the invention is to provide: a force feed lubricator ofthe character above described which may be readily applied toc'ar trucks and which will operate findefinitely without "attention except for pe- 4 riodic rep'lenishments of the oil supply in the gqtank' of the device. 7. i

'QOther objects and advantages of the present' invention will-beco'mei apparent as .a description of the same proceeds-andthe'invention will be best understood, from af'consider- 'ation-of the following detailed'description taken in connection with Ithe accompanying drawings forming a part ofthe. present. specification' with, the understanding, 7 however, that the invention is not confined'to any strict I conformitywiththe showingof the drawings -but may 'be'changed or-modified so longas such changes or modifications mark no materialdepar'ture-from the salient features of the invention,. as expressed in the appended claims. In the drawings I Figure 1 is a view in plan of a locomotive or railroad car truck'showing the application of the present force feed lubricator;

on Figure 2 shows the lubricatoridevice partly "in end elevation and section. 7 Figure 3 is a view in side elevation of the device showing the oil distributing pipes and -manifold therefor;

. Figure 4 is'a View of the inner face of a standardbearing brass showing the means employediforlejectingthe oil therethrough to 1. the face of the bearing.

Referring Imore' particularly to the drawings wherein like numerals of'reference indicate correspondingparts throughout the several views, the numeral '1 indicates an oil supply'tankwhich is here shown as of cylindrical construction and relatively'long.

.Thistank when applied'to a car truck, such for example as thatindicated generally by'the-numeral 2 and 'shownin Figure 1, is mounted directly above an axle of the truck, preferablyupon supporting bands 3:m ountled upon t hetruck' frame transversely of" and --above the axle .in such a manner as to pro- .vide'acradle for .the tank. a

The tank 1 has, opening through the wall thereof, a'nipple 4, this nipple beingprefv erably welded 'tolthe tank'wall and having external screw threads for the'reception of a "sleeve: 5' whi ch is normally closed at its upper end byia cap 6 whichhasthreaded con- "nection therewith, as shown in Figure 2. The sleeve ..5 :when secured in place upon the nipple 4 maintains in position inthe nipplea wire gauze strainer 7 through which the oil introducedto'the tank must pass before it-is used tolubricate'the truck bearnin'gsx. In order to prevent damage tothe strain'er'by the careless insertion of a funnel spout, the sleeve 5 is provided with a pair 0f balfie plates18. arranged in the staggered ure'lation shown; 1

From the underside of'thetank 1 which would-beat a point. diametrically opposite the inlet sleeve 5 in the case that a cylindriacal tanki's employed, there is secured a-suitable stud 9 which has a reduced terminal portion 10 provided with screw threads. The lower face of this terminal portion is formed to provide a seat-'11 for a'valve, hereinafter described, and'formed longitudinally through the stud is a pair "or more of oil outletpaspartly in longitudinal sages 12 which, at their inner ends, open into the tank 1, as shown. In the central portion of the stud there is formed a bore 13 which at its external inner end is of reduced diameter and internally threaded to receive the end of a bolt 14.

This bolt 14 passes through a sleeve 15, one end of which slidably extendstinto the bore 13. This sleeve carries, intermediate its ends, a disc valve 16 which is formed to position, during certain periods in the op eration of the lubricator, upon the seat 11 to close the passage 12 and prevent flow of oil from the reservoir. v V

The reduced portion of the stud 9 threadably engages in one end of. a. cylinder 17 which cylinder has formed transversely thereof and adjacent the end attached to the stud 9, an. apertured partition 18-.

In the lower end of the cylinder 17 a piston head 19 positions, there being secured to the face of this piston heada suitable washer 20 which is heldto frictionally engage the wall of the cylinder. The piston head 19 carries a relatively heavy rod 21 and. this head is prevented from accidental displacement from. the cylinderby thecap 22 which threadably engages the lower end of the cylinder and through which the rod 21 passes.

A portion of the bore through the. cap 22 is of av diameter materially greater than the rod. 21 so that space is provided for packing material 23 and this packing material is held in place by a suitable gland 24 which in turn is forced inwardly by a nut'25- which receives the outer end of, the; gland and which has threaded engagement with a. re duced portion 26. forming a terminal part and extension of the cap 22;

7 At its outer end the rod 21 is. threaded as at 27 to receive the adjusting nut- 28 and locking nut 29.

As previously stated the lubricator is so mounted on a truck as torposition over an it is fixed by thelocking nut29. A portion of an axle is indicated in Figure 2 by'the nu- :ineral 30.

In order to maintain the/piston. 19 in out-' wardly extending or projecting position there is housed within: the cylinder 17 between'the partition. 18 and the face of the piston a coiled spring 31 0f suitable weight, the oilice of which is to keep-thepiston. in the outer or lower end of the cylinder.

Leading from the upper end of the cylinder17 is an outlet nipple 32,: which at its outer end opens into one branch of a threeway coupling 33, a second: branch of this coupling having joined thereto anupwardly extending pipe 34 which, at its upper end opens into an oil manifold 34' which is supported at some point adjacent the upper part of the oil reservoir 1, preferably by welding or otherwise securing it directly to the body of the reservoir. The third outlet of the coupling is connected by a suitable coupling witha lateral pipe 35 which opens into the casing of an adjustable spring pressed valve 36. This valve may be of any suitable type which can be so adjusted that a predetermined amount of pressure must be applied thereto before it will open and it is so positionedthatthe pressure must be applied from the pipe 35 so that when it opens it will permit the passage of oil fromthe pipe 35 into the return pipe 37 which leads back to the oil reservoir 1, discharging preferably through: the top. .thereoflas indicated at 38.

..From-the' n1anifold34 there extends four lead-off nipples 39, one for each of the hearing brassesofthevtruck and each of these nipples has coupled thereto by a reducer couis indicated as a whole by the. numeral 42 and the oil pipe. extending longitudinally there-" I through is indicated by the numeral 43. Two "of thesebrasses, which areof usual construc tion, are employed in association with each axle, one adjacent eachwheel thereof in the usual well-known manner and each of the.

pipes 43 thereof has one of the oil supply pipes 41 connected thereto-j Suitable oil escape apertures 44 are formed in the face of the brass and each of these apertures connects with. the arcuate distributing grooves. 7

Extended into the reservoir 1 through the top: or upper portion thereof is a graduated measuring rod 46 having a head 47 which rests upon the wall of the tank to hold the rod: in position. The height of the oil in the tank can be readily determined by withdrawing' this rod and observing the point where the oil film ceases.

In operation, the present lubricator is mounted, as previously described upon suitable supports; over an axle of the truck and the piston rod nuts 28 and 29 are then adjusted. so-that they'will be in close proximity to the axle. After the proper connection has been made between the pipes 41 and the brasses of the truck, the spring controlled check valve 36. is adjusted to: approximately the correct position and the lubricator is then ready for use.

During the running of the truck to which the lubricator is appliedthere will be a slight verticalmovement of the truck frame upon the supporting axles which movement will cause the axle adjacent the lubricator to come into contact with and move the piston rod 21, thus forcing the piston head 19 upwardly to eject oil from the cylinder into the lateral lead-ofi pipe and into the manifold from which it will be distributed through the pipes 41 to the various brasses to lubricate the same. It will be obvious that upon certain occasions when the pressure of the axle against the piston rod will be greater than upon others, more oil Will be ejected from the cylinder than can be carried off by the manifold and the pipes 41 and when this occurs a portion thereof will be forced through the valve 36 into and through the pipe 37 which leads back to the reservoir, thus rupture of any of the pipes through the application of too great pressure will. be avoided.

Having thus described my invention, What I claim is 1. A bearing lubricator for trucks of the character described, comprising a receptacle designed to be positioned over an axle of the truck, an apertured lead-0E body at the uni7 derside of the receptacle, a piston cylinder attached to said body and having the same opening thereinto, a check valve controlling the passage of oil through the lead-off, a piston within the cylinder having a rod extending downwardly to a point adjacent the underlying axle, adjustable elements carried upon the lower end of the rod for governing the clearance between the same and the axle, lead-off means from said cylinder at the upper end thereof, a manifold for receiving oil from the lead-off, and distributing pipes leading from said manifold to the bearings of the trucks.

2. A hearing lubricator of the character described, for trucks, comprising an oil receptacle positioned over an axle of the truck, a stud formed on the exterior surface of the receptacle wall and having passages formed therethrough and in communication with the interior of the receptacle, a cylinder threaded at one end onto said stud and having said passages discharge thereinto, said cylinder having an apertured partition wall therein, a stem carried by said stud, a valve mounted on said stem to close said passages, a piston mounted in said cylinder and having a rod extending from the other end thereof to a point in close proximity to said axle, resilient means interposed between said partition wall and said piston normally urging the latter outwardly, and means for conducting oil from said cylinder from a point adjacent said valve to bearings for said axle.

3. A hearing lubricator of the character described, for trucks, comprising an oil receptacle positioned over an axle of the truck, a stud formed on the exterior surface of the receptacle wall and having passages formed therethrough and in communication with the interior of the receptacle, a cylinder threaded at one end onto said stud and having an apextured partition wall therein, a stem carried by the stud, a valve mounted on said stem to close said passages, a piston mounted in said cylinder and having a rod extending from the other end thereof to a point in close proximity to said axle, a manifold comprising an elongated casing mounted upon said oil receptacle, a plurality of pipe lines leading from said manifold to bearings of the truck, a pipe line leading from said cylinder from a point of the latter adjacent the end connected with said stud, to said manifold, and a check valve controlled pipeline in communication with said last mentioned pipe line and leading therefrom to the oil cylinder.

In'testimony whereof I hereunto aflix my signature.
