CAR-JOURNAL BEARING.

SPECIFICATION forming part of Letters Patent No. 591,807, dated October 19, 1897.

Application filed November 4, 1896. Serial No. 611,087. (No model.)

To all whom it may concern.-

Be it known that we, VILLIAM RUSH'ION Bowman and JOHN RUsHToN BOWKER, residents of lValtham, Middlesex county, Massachusetts, have invented certain new and useful Improvements in Lubricators for J ournals of Car and Locomotive Axles, of which the following specification contains a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof, and in which- Figure 1 is a longitudinal vertical section of the improved lubricator and of the jour na l-box containing it. Fig. 2 is a transverse vertical section on line 2 2 of Fig. 1, and Fig. 3 is a view similar to Fig. 1 of a modified form of lubricator.

The invention relates to that class of lubricators which are provided with a pump for supplying the journal with oil from the bot tom of the box.

The object of the invention is to render the piston of the lubricator operative, wholly independent of the journal, by allowing it free movement in the barrel or receiving chamber or chambers, so that the piston will be moved back and forth by the jolting or lateral movement of the car; also,to simplify the lubricator, so that no valves or parts other than the piston and its barrel or chamber will be required; also, to render the piston sensitive to such jerky or jolting movements by mounting it upon wheels or rollers travel ing on the bottom of the box.

The invention consists primarily, therefore, in one or more barrels or piston-chambers provided with an outlet nozzle or nozzles to discharge the oil upon the j ournal,and a piston freely mounted in said barrel or barrels, so as to be moved back and forth by the jolting or lateral movements of the car, and the Whole being adapted for location in a journal-box independent of the journal.

The invention also consists in the construction and combinations hereinafter described, and specifically pointed out in the claims.

A represents the journal-box, the bottom portion of which forms the oil-reservoir, and B is the journal mounted in said box. These parts may be of any approved construction.

The lubricator is mounted in the bottom of the box and comprises two piston-barrels E E, mounted at opposite ends of the box-bottom with their open ends facing each other. In Fig. 1 both of these barrelsor chambers are provided with discharge-nozzles H H and lateral inlet-openings I I, for the free entrance of the oil contained in the box, while in Fig. 3 but a single discharge-nozzle is provided,the other barrel or chamber E simply serving as a piston-guide. In Fig. 3 the nozzle is in the form of a pipe overlying both pistonbarrels E E, extending practically from end to end of the box and having discharge-apertures in its upper side, which lies adjacent to the under side of the journal B. These piston barrels or chambers are oblong in cross-section and rest fiat upon the bottom of the box.

The piston F is in the form of a plain oblong block and extends at its ends into the two piston-chambers E E, and fits sufficiently snug to expel the oil through the nozzle or nozzles, but is free to be reciprocated by the jolting or lateral vibration of the car. When the piston is moved in one direction, one inlet-port I will be opened for the free entrance of the oil, and theoil will be forced out of the opposite chamber E.

G G are rollers or wheels pivoted at opposite sides of the piston between the barrels or chambersE E, and running on the bottom of the box' A. 7

As the inlet-ports I I open into the box A below the level of the oil and the piston ends open and close them it is obvious that no valves are required.

The whole lubricating mechanism may be readily inserted or removed from the box for cleaning or repair.

What we claim is 1. A lubricator for j ournal-boxes, comprising a barrel or casing to rest in the bottom of the box and having an inlet and a suitable discharge-nozzle to direct the oil upon the journal, and a freely-movablepiston for'said barrel or casing, operated solely by the vibra tion of the car and independent of the journal, substantially as described. v

2. A lubricator for journal-boxes comprising piston-barrels adapted to rest at opposite ends of the bottom of the j ournal-box, and one I or both provided with an inlet and a dischargenozzle to supply oil to the journal, and a piston working freely at its ends in said two barrels past said inlet or inlets and operated solely by the vibrations of the car, substantially as described.

3. A lubricator for journal-boxes comprising the oblong piston barrels or chambers to rest on the bottom of a journal-box'at opposite ends thereof and provided with an inlet and a discharge-nozzle to direct the oil up to the journal, and a piston in the form of an oblong block, working freely in said two barrels or chambers and operated by the vibrations of the car, substantially as described.

4:. A lubricator for journal-boxes, comprising the two piston-barrels to rest on the bottom of a j ournal-box and having an inlet and a nozzle to discharge the oil upon the journal, and the piston working in said two barrels or chambers, and provided therebetween with rollers or wheels running on the bottom of the box, substantially as described.

5. The combination with the box and the journal, of a lubrioator comprising a pistonchamber in the bottom of the box, having an inlet and a nozzle to discharge upon the overlying journal, and a freely-movable piston working in the said chamber past said inlet and operated by the vibrations of the car, substantially as described.

6. The combination with the box and jour:

nal, of a piston barrel or chamber in the bot- 7 YVILLIAM RUSHTON BOVVKER. JOHN RUSHTON BOWKER.
