UNITED STATES JAMES JQHENNESSY, F NEW YORK, N. Y.
LUBRICATOR.
Application filed May 22, 1923. Serial No. 640,646.
My invention relates to journal box lubricators such as are usedupon railroad rolling stock and consists in a modification of my copending application Serial Number 578,-
O18, filed July 27, 1922.
The particular object of my present invention is to afford a gravity-operated return device for the pump plunger to be used in place of the returnv spring shown in the Y0 above-mentioned application,l and, in the accompanying drawings illustrating my present invention,-
Figure 1 is a vertical longitudinal section through my improved lubricator. i
Figure 2 is a vertical transverse section on lin-e 2 2 of Figure l.
In these drawings, A represents the axle of a wheel to be lubricated and B indicates the collar or flange of the wheel which operates the lubricator. The body of the lubricator is box-like in general appearance and comprises a bottom wall 1 and side wall 2 from the former of which rises a central projection or wall 3 and adjacent thereto a cylindrical projection 4. The lower portion of wall 3 is provided with a horizontal passage 5 which forms a pump cylinder and receives the sliding plunger 6 equipped with a flop valve 7. The inner Iend of passage 5 communicates with the lower end of cylinder 4 and upon operation of the plunger supplies lubricant to the axle through cylinder 4 which is equipped with a ball check 8.
The plunger 6 is moved back and forth by a rod 9 provided with a rigid connection 10 to plunger 6. Rod 9 extends through the side wall 2 of the lubricator body and is adapted to contact at its outer end with the collar or flange B of the wheel. The inner end of rod 9 is slidably journaled in wall 3 and projects into a recess 11 formed in the upper part of the latter. Extending through recess 11 at right angl-es to rod 9 and plunger 6 is a pintle 1Q journaled in the wall 3 at opposite sides of recess 11. This pint-le has a finger 13 fixed to its middle portion and extending upwardly into contact with the inner end of rod 9. Secured to the outer ends of pintle 12 are weights 14. It will be noted that these are secured off-center or eccentrically so that they are held by the pintle, finger 13 and rod 9 in such position that their weight tends to turn the pintle and finger 13 to move rod 9 to the left. The weights, pintle7 and finger form l a yielding device for returning rod 9 and plunger 6 to the left after each movement `of these parts to the right by the thrust of with the axle by any suitable means, such as the pan 15 illustrated, which .is yieldingly supported against the axle by spring 16.
The construction shown in my present invention may be advantageously employed at times when the spring shown in the abovementioned application is undesirable. It is not subject to variations as are ordinary manufactured springs, nor will it crystallize and break as springs of poor quality often do.
The rod and plunger connection 10 may be adjusted lengthwise of rod 9 without inter ference by the return device as is the case with the spring construction shown in my copending application.
I claim:
1. In a journal lubricator, a horizontal pump cylinder.y a piston in said cylinder, a wall above said cylinder7 a transverse pintle journaled in the upper portion of said wall, weights at the sides of said wall fixed offcenter on the ends of said pintle, an up standing finger fixed to the middle of said pintle, a horizontal slidable rod engaging said linger and ext-ending outside of said lubricator to contact with a movable actuat-v ing element, and a rigid connection between said rod and said piston.
2. In a journal lubricator, a box-like lubricant reservoir7 a wall in said reservoir having a passage in its lower portion forining a pump cylinder7 a plunger therein, a recess in the upper portion of said wall.v a pintle extending at right angles to said cyl inder passage through said recess and journaled in the Walls thereof, Weights eccentrically ixed on said pintle at the sides of said Walls, a nger fixed on the middle of said pintle in said recess, an actuating rod parallel with said plunger extending through an outer Wall of said reservoir to Contact With a Wheel hub or the like and extending through a Wall of said recess to Contact with said finger, and a rigid connection between 10 said rod and said plunger.
In testimony whereof I hereunto affix my signature this 12th day of May, 1923.
JAMES J. HENNESSY.
