UNITED STATES JAMES J. HENNESSY, OF NEW YORK, N. Y.
JOURNAL LUBRICATOR.
Application filed September 20, 1921.
To all whom it may concern:
Be it known that I, JAMES J. HENNnssY, a citizen of the United States, residing at city of New York, State of New York, have invented a certain new and useful Improve ment in Journal Lubricat'ors, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, forming part of this specification.
My invention relates to journal lubricators such as are used on railway rolling stock, and consists in an improved lubricant reservoir and pumping mechanism.
In copending applications filed by me, Serial Number 397,3 l1, and Serial Number 397,342 I show somewhat similar reservoir and pumping mechanisms in which the pump plunger is actuated in one direction by positive engagement of an operating rod by a journal or wheel element and is actuated in the opposite direction by the energy of a compressed spring.
The main object of my present invention is to eliminate the use of a spring for the purpose mentioned, and to provide a positive actuation of the operating rod in both directions.
In the accompanying drawings, which illustrate a selected embodiment of my invention,
Figure 1 is a longitudinal section through my lubricator as mounted upon the journal of a railway car.
Figure 2 is a transverse vertical section on line 22 of Figure 1.
The lower portion of the reservoir 1 forms an oil well and the upper portion of same seats a waste pan 2 adapted to hold the usual cotton waste against the journal and, away from the pump mechanism. The pump cyl inder is indicated at 3 and is provided with the usual plunger 4 which is designed to re ciprocate in a horizontal direction. Extending through the reservoir from end to end and projecting beyond the end walls thereof is a contact rod 5 which is connected to plunger 4 by means of alever 6 and a stud 7, the lever being fulcrumed to the bottom of the reservoir at 8.
Cylinder 3 terminates near the center of.
Specification of Letters Patent.
Patented July 25, 1922.
Serial No. 501,868.
The opposite end of rod 5 is adapted to be engaged by the side of a hub 13 of the wheel mounted on journal A.
It is well known that in the travel of railway rolling stock, ,there is a constant shifting back and forth between the journal and the journal box, and I rely upon this shifting to operate the pump by alternate contact of the hub B and collar 12- with the respective ends of rod 5. This is a positive operation which does not depend for its functioning upon a spring such as has hitherto been used and which is subject to the possibility of being broken or being clogged with dirt or other foreign matter.
While I have shown rod 5 of a length somewhat less than the distance between collar 18 and hub B, this is a preferred arrangement not essential, as the collar 13 may be positioned right against the adjacent end of rod 5.
I contemplate this and such other changes as are likely to be suggested in the commercial development of my devices, without any departure from the spirit of my invention, as set forth in the following claim.
' I claim:
In combination with the journal and hub of a car wheel, a collar adapted to be clamped to said journal at a point spaced from the wheel hub, a journal lubricator applied to said journal between the wheel hub and said collar, said lubricator comprlslng a lubricant reservoir and a pump for feeding lubricant from said reservoir to the jo urnal, a pump operating rod extending through the opposite walls of said lubricator with its opposite ends respectively oppos ng the wheel hub and collar, and a connectlon between said rod and said pump.
In testimony whereof I hereunto afiix my signature this 29th day of June, 1921.
JAMES J. HENNESSY.
