Description
Oct. 28, 19 1- J. J. HENNESSY LUBRICANT DISTRIBUTOR Filed July 5, 1940 INVENTOR.
JAMES J. HENNESSY Patented Oct. 28, 1941 UNITED STATE s PATENT OFFICE 9 Claims. (01
The invention relates to mechanical lubricators of the type particularly adapted for use in railway journal boxes, and the invention consists in the means by which lubricant pumped to the journal is distributed over the journal surface.
In an application for patent filed by the present inventor December 1, 1939, Serial No. 307,057, there is illustrated a mechanical lubricator applied to a journal boxhaving an Association of American Railroads contour, there being a relatively short distributor plate applied to the journal and receiving lubricant from the pump, there being hanks of yarn packed under the journal between the ends of the distributor plate and the ends of the journal. Theamount of this yarn, the manner of its packing, and its effectiveness for the intended purpose will vary with the experience and carefulness of the workmen.
O-ne object of the present invention is to provide a distributor unit including a metal platelike member for application to the journal and pads of absorbent material associated therewith so as to obtain the beneficial results of the loose yarn packing previously used and also to obtain more uniform results from the absorbent material.
Another object of the invention is to facilitate the application and removal of a distributor unit, extending substantially the full length of the journal, when the space between the journal and the adjacent journal box wall and pump members is restricted as is the case with an assembled A. A. R. journal and box.
In some cases it has been necessary to jack up the box and remove the journal bearing and wedge and then lower the box onto the axle before the lubricator device could be applied or removed, and it is a further object of the present invention to make possible the application and removal of the lubricator device and, particularly, a distributor of the desired type without such manipulation of the box and journal.
In the accompanying drawing which illustrates a selected embodiment of the invention- Figure 1 is a vertical longitudinal section through a journal box equipped with a mechanical lubricator including the novel distributor, the
journal, journal bearing and wedge being shown also.
Figures 2 and 3 are detail vertical transverse sections taken on the corresponding section lines of Figure 1.
The journal box I, axle 2, with journal 3, bearing 4 and wedge 5 are of usual construction and require no detail description. The mechanical lubricator consists essentially of two units, a pumping unit 6 and a distributor unit I. The pumping unit may be as disclosed in the abovementioned application, Serial No. 307,057, and will not be described here except to note that a reciprocating piston 8 is actuated through a lever 9 by the play of the axle and journal longitudinally of the box to draw oil from the bottom of the box into a cylinder in the pump body In from which it is discharged through a passageway H to a cup-like recess in which there is seated the spherical lower end 12 of anarm l3 of the distributor device.
Arm I3 is pivoted at l4 to depending hinge bu'tt elements I5 on the upwardly-facing concave plate l6 which has upstanding ribs ll at its ends disposed to engage the surface of the journal. A lubricant passage I8 extends through elements II, l3, I4 and one of elements l5 to the upper face of plate It. A spring l9 thrusts plate l6 and the swinging end of arm I3 away from each other whereby the plate is held against the journal and is pivotally supported by element I2 on member l0.
At each end of plate "5 is a shallow pan 20 with its end portions 2| at opposite sides of the longitudinal center line of the lubricator inclined upwardly. Upright side flanges 22 extend from end to end of each pan 20 and end flanges or lips 23 at the ends of portions 21 extend horizontally. Elements 20, 2|, 22 and 23 form a receptacle for one or more felt pads 24 having arcuate upper faces for engaging the journal, having end portions shouldered at 2'5 for engaging pan lips 23, and having depending tongues 26 extending through openings in pans 20 and arranged to extend into the lubricant in the bottom of the journal box.
Hinge lugs 21 depend from plate l6 and hinge pins 28 extend through lugs 21 and pivotally mount arms 29, the outer ends of which are pivotally anchored to the bottom walls of pans 20 whereby the latter and the pads carried thereby are free to swing about pins 28. Springs 30, coiled about pins 28, bear against the bottom of plate I6 and pans 20 and thrust the latter upwardly against the journal.
Pads'24 are saturated with oil which travels longitudinally of the journal beyond the ends of plate t6 and also with oil which is lifted by capillary attraction from the bottom of the box. They provide for the wiping of surplus oil from the end portions of the journal or for the distribution of oil to the end portions of the journal as may be required.
The hinging of pain; 20 on plate I6 and the yielding nature of the portions of the pads projecting upwardly and downwardly from pans 20 facilitate the insertion of the distributor unit through the space between the end of the journal and the bottom wall of the journal box and the upwardly curved end wall, such insertion and removal being accommodated also by the movement of arm l3 towards plate I6. While spring [9 is adequate to hold the distributor elements against the journal, it is readily compressed between the fingers and thumbs of workmen when the distributor is to be inserted or removed to, and from its functioning position. In practice, the distributor unit 1 will be inserted beneath the journal before the pump unit 6 is applied and, in the event of replacement, the pump unit will be removed before the distributor unit is removed. I
The interengagement between the pads and the, pans where tongues 26 pass through the bottom of the pans and at shoulders 25 holds the flexible pads in place and prevents their be ing drawn out of position by contact of the rotating journal. Grooves such as are indicated at 3|, for example, may be formed in the pads to provide pockets for lubricant pools. If the bearing becomes overheated because defective, or
for any other cause, the felt pads will char, and
smoke discharged from the box will attract attention to the box so that the cause of the overheatingmay be remedied.
These elements and other elements .of the structure may be varied and some features may be omitted entirely without affecting the essential features of the device, and the exclusive use of those modifications which come within the spirit of the claims is contemplated.
What is claimed is: 1.
