Application lled August 28, 1924. v.Serial No. 218,679.

My invention relates to a system for lubricating 4the journal bearings in the journal box of a railroad car; the invention having for its object the provision of means whereby the journal bearings will be automatically 'l tional view of the lower portion of a journal box and my lubricating system, with portions broken away. 'Figure 3 is a sectional end elevation, taken v substantially on the line 3-3 of Figure 1,

looking in the direction of the arrows.

Figure 4 is a vertical sectionalview taken substantially :on the line 4-4 of Figure 1.

In the particular exemplification of the invention as disclosed in the drawing, the outer end of thel 'ournal is shown at 10, mounted in the. usual journal box which is enerally indicated at 11; the journal box. eing of the -usual standard construction, provided with the Babbitt-metal 12 in direct contact with the journal and beneath the brass 13 which is held in place by the usual. wedgeblock 14.

` The bottom of the journal box is pro-l vided with ay cylinder 15 of proper length .interme iate of its ends, is provided with a and dimensions; the cylinder being shown preferably provided with

nipples

16, 16 which are externally threadedand adapted to extend through suitable holes in the bottom of the journal box. The nipples are preferably provided with ports 1.7 in the sides to permit draining of the journal-box; while the exterior ends of the nipplesare provided with suitable'. caps 18 screwed l thereon. The caps 18, not only firmly secure the cylinder in place but may also hold suitable washers in place-on the vnipples to rovide fluid tight connection as shown in igure 2; while the caps at the same time provide closures for the nip les; the nipples 16 being intended for draining and cleaning out the cylinder .and the lower part of the journal-box l when occasion requires.

The ends of the cylinder 15 arel shown preferably provided with

removable caps

19 and 20, which screw onto the cylinder ex-` terior and are preferabl provided with the flanges having dished si es as shown in Figue 3, so as to provide suitable support vfor the ends of the c linder and maintain it in spaced relation with the bottomv of the jour-` nal-box, while at the same time preventin accidental unscrewing ofthe caps. The hu of the cap 20 is shown socketed or dprovided with an internal boreto receive an rovide bearingfor the spindle or shaft 21 o a suitable spiral or feed screw 22 which is vdisposed lengthwise of the cylinder. The cap 19 is apertured and shown provided with a bushin 23l for the passage or sha 21. j

The outer. endof the spindle or shaft 21 is preferably angular yin cross-'section and shown provided with `a sprocket 24 which of the y spindle is slidably mounted'on. the spindle or Shaft so as to rotate'therew'ith and at the Same time permit movementin keeping with the longitudinalmovement o f the journal. i The sprocket 24 is adapted to. receive a sprocket chain 25 which extends about al sprocket 26 which is suitably secured to the end of the journal 10 so as to rotate with the journal; the sprocket 26 in the exemplifica'tion being provided with a hub, extending from one side thereof, terminating in a flared portion or flange whereby the sprocket mayk be secured to the end of the journal as for examplezby means of suitable bolts or screws as at 27 in Figure 1. .v 5

The c linder 15, preferably, at a point the oil may plurality of openings28 whereby With my enter or iow into the cylinder.

. improved system, the bottom of the journal lbox is intended to be filled with oil to a into the oil holding portion .of thebox; the

dished portion of the plate. being provided with a suitable numberl of minute openings.

The cylinder 15 is thus fully immersed, thus causing the oil to enter the cylinder through the ports or openings 28.

T e cylinder is shown provided with a pair of conduits 30' and 31 which are pref' erably arranged to communicate with opposte ends of the cylinder 15. These

conduits orv tubes

30 and 31 are arranged to extend toward the outer end of the journalbox and lead upward beyond the end of the journal 10; with the upper ends of the conduits or tubes arranged to communicate with or extend into suitable longitudinal passagesl arranged Iin the brass 13. These passages extend from the outer end of the brass preferably to a point intermediate of the ends, where the brass 13 with the Babbitt-metal 12 are both provided with .a vertically disposed port or opening 32 extending through to the journal 10. The upper end of the port 32 in the brass 13 is shown preferably closed by a suitable plate as at 33 so as to induce the oil to flow out through the lower end of port 32 and therefore onto the end of the journal 10. The opening 32 is preferably of a size suiiicient to retain a considerable quantity of oildischarged therein by either conduit 30 or 3l; and in the event that the quantity of oil fed into the opening or well 32 is in excess of the oil being taken up by the bearings, the excess oil will `flow back through the non-feeding conduit or tube, either 30 or 31 as the case may be, into the cylinder 15 and again forced through the feeding conduit, thus maintaining constant circulation and an economic use of oil.

With my improved construction, it is apparent that the oil entering the ports 28 of the cylinder l5 will be caused to travel toward one end of the cylinder when the spiral or feed-screw 22 is in operation; that is to say, when the car is in motion, rotation of jlpurnal 10 causes the screw or spiral 22 to e rotated through Ithe medium of sprocket 26, sprocket chain 25 and sprocket 24, thereb forcing the oil toward one end of the cy inder 15 and therefore into the conduit or tube communicating with said and therefore cause the oil to be f end of the cylinder. Movement of the car .and its journal in the opposite direction will cause the spiral to reverse its o eration toward the opposite end of thecylinder and upward through the tube communicating with said end; it being understood that the oil is forced through one conduit or tube at a` time, depending upon the direction of'travel of the car. The oil forced upward through the tube, passes lthrough the respective longitudinal passage in the 'brass and empties into the port 32. In order that the oil may quickly find passage to the ends of the Babbitt-metal and thus ensure the entire bearing surface of the journal being fully lubricated, I prefer to provide the bottom surface In the particular exemplification, the

tubes

30, 31 are each shown provided with a head or intermediate connection 35 to receive the portions of the tubes which are rigidly connected with the cylinder 15; although it lis evident that the tubes may be made continuous and vconnected in any suitable way to' the cylinder; the construction illustrated permitting easy assembly of the parts and also enabling the tubes to be replaced or the cylinder to-be removed without disconnecting the upper ends of the tubes.

As is a parent from the construction shown Iin t e drawing, an automatic oiling system for the car or journal box is provided which will ensure complete lubrication after the car or journal box has been supplied with a suilicient quantity of oil; the excess oil delivered at the top of the journal being allowed to pass through the non-feeding tube back into the c linder from whence it is again forced t rough either one of the conduits or tubes. When the oil is to be renewed and the cylinder with the lower part of the journal box is to be drained, it is evident that removal of o the

caps

18, 18 will allow the oil to drain from the cylinder and also from the journalbox by means of the' holes in the sides of the nipples, thus permitting a complete draining of the cylinder and the journal-box.

I have shown and described what I believe to be the simplest embodiment of my invention and have described the same in 'terms which are employed merel as terms of description and not as terms of `mitation, as structural modifications are possible and may be made without, however, departing from the spirit of my invention.

What I claim is:

ios p 1. A system of the character described,

' comprisi in combination with a journalbox, a c linder located in the'bottom of the journalx and provided with clean-out nipples adapted to. extend through the bottom of the journal-box, closures for said terminating in a common port extending4 through to the bottom of the brass, a cylinder located in the bottom of the journalbox and rovided with inlet ports in the side wall or admitting oil into the cylinder inder disposed journal-box whereby the cylinder is re-I from the journal-box, an outlet from the cylthrough the wall of the movably held in lace and the oil ma be drained, a pair of conduits extending rom opposite ends of the cylinder and communieating with the ports in the brass, a feedscrew rotatably mounted in the cylinder adapted to force the oil toward either end of the cylinder, the spindle of the feed-screw being disposed through the end wall of the cylinder and provided with a sprocket slidably mounted thereon, a sproc et secured to the outer end of the journal, and
