JOURNAL LUBRICATOR Filed Oct. 29, 1947 WEI.
INVENTOR ATTORNEYS Patented Oct. 16, 1951 UNITED STATES PATENT OFFICE 2,571,235 JOURNAL LUBRICATOR I Alfred A. Hamer, Alexandria, Va.
Application October 29, 1947, Serial No. 782,929
3 Claims. (Cl. 308-87) This invention relates to journal lubrication, and particularly to journals mounted in journal boxes of railway rolling stock.
An important object of the invention is to provide a body portion constructed preferably of rubber known as Neoprene or other oil and acid resistant rubber composition, the construction of the body portion being such as to provide a reservoir with the bottom of the journal box in which the body portion is positioned.
Another important object of the invention is to so construct the body portion that the ends of the reservoir formed thereby, will be sealed against foreign matter entering the reservoir to impair the lubricating qualities of the lubricant.
Another important object of the invention is to provide means for conveying the oil in the reservoir, to the surface of the journal, through capillary attraction, the lubricant conveying means being in the form of suitable fiber material, such as fiber glass wool against which the journal contacts to pick up the lubricant which is carried to the journal and bearing.
Still another object of the invention is to provide a lubricator of this character wherein the body portion and web or wick will be maintained in a flat condition in contact with the journal throughout the entire length thereof, thereby insuring against the fibrous material or wick buckling to cause what is commonly known as waste grab which usually results in an overheated journal box and the resultant damage to the journal and in a great many instances, the rolling stock in general.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawing Figure 1 is a longitudinal sectional view through a journal box and lubricating device constructed in accordance with the invention.
Figure 2 is a sectional view taken on line 2-2 of Figure 1.
Referring to the drawing in detail, the reference character 5 indicates a journal box in which the journal 6 operates, the journal 6 contactin the journal bearing I in the usual and well known manner.
The device forming the subject matter of the which is of a length to extend throughout the length of the bottom of the journal box, the body portion being constructed preferably of rubber material of the oil and acid-resistant type, having absorbent qualities.
The body portion 1 is of a width to extend across the bottom of the journal box as clearly shown by Figure 2 of the drawing, the upper surface thereof being curved to conform to the curvature of the journal operating within the journal box, to the end that slight pressure will be directed upwardly against the journal.
The lower portion of the body I is cut away providing an oil reservoir 8 with the bottom of the journal box, the construction of the body portion being such that the reservoir 8 is closed at its front end by the wall 9 and closed at its rear end by the wall l0, thereby excluding foreign matter which would otherwise enter the oil reservoir to impair the efficiency of the oil.
An opening II is formed in the body portion I adjacent to the front end of the journal, so that lubricating material may be supplied to the reservoir 8.
Vulcanized to the upper curved surface of the body portion I, is the wick I2 which is constructed preferably of woven fiber glass wool or wear-resistant fabric material capable of absorbing the lubricant within the reservoir, and carrying the lubricant to the position where it will be picked up by the rotating journal, by capillary attraction.
As clearly shown by Figure 2 of the drawing, the ends of the wick I2 extend through openings formed in the body portion I, the extremities [3 thereof extending into the reservoir where they are submerged in the oil contained in the reser- Molded or otherwise secured within the body portion adjacent to the lower outer edges thereof, are reinforcing ribs I4 which are constructed of semi-rigid rubber, or metal if desired. These reinforcing ribs hold the flexible body portion I extended at all times, and permit the application of the body portion under the journal in such a way that the body portion will not buckle and become wedged to defeat the purpose of the invention.
Those ribs also tend to hold the body portion extended at all times preventing any possibility of the body portion I being carried upwardly by the rotation of the journal within the journal box.
From the foregoing, it will be seen that due to the construction shown and described, I have provided lubricating means for journal box construction, wherein'the journals and bearings are constantly fed with lubricant to maintain the journal cool.
It will further be seen that due to the construction, the lubricant contained within the reservoir of the device is maintained clean and guarded against foreign matter entering the reservoir to impair the efficiency of the lubricant.
In view of the fact that the body portion 1 is constructed of rubber material, it will be obvious that the body portion will adapt itself to the contour of the interior of the journal box, insuring a close fit therebetween to hold the body portion 1 in place.
It will be seen that the wick which carries the lubricant to the journal, contacts the journal throughout the entire length of the Journal insuring the lubrication of the journal throughout the entire length thereof.
What is claimed is:
1. The combiantion with a journal box and journal operating therein, of a journal lubricating device comprising a solid yieldable body portion consisting of a block of absorbent rubber material, fitted in the journal box in contact with the side walls of the journal box, said body portion having a recess in the bottom extending throughout substantially the entire length thereof forming a lubricant reservoir with the bottom of the housing in which the body portion is positionedfawick secured to the upper surface of the body portion, said wick being extended through openings formed in the yieldable body portion with the ends thereof disposed within the reservoir, whereby lubricating material is delivered to the journal from the reservoir, and said body portion having an opening through which lubricating material is directed to the reservoir.
2. The combination with a journal box and journal operating therein, of a journal lubricating device comprising a solid yieldable body portion constructed of a block of absorbent rubber material-fitted within the journal box, said body portion contacting the side walls and said recess providing a lubricant reservoir with the bottom of the journal box, the. ends of the reservoir being closed, a wide wick positioned ,on the upper surface of the body portion for contact with a journal extending into the journal box, portions of the wick being extended through the body portion with the ends thereof disposed within the lubricating material contained in the reservoir, whereby lubricating material is delivered to the journal by capillary attraction, and
said body portion having an opening establishing communication between the reservoir and atmosphere, whereby lubricating material may be delivered to the reservoir.
3. The combination with a journal box and journal operating therein, of a journal lubricating device comprising a yieldable body portion having openings extending vertically therethrough fitted within the bottom of the journal box, filling the bottom of the journal box, said body portion having a recess defining a reservoir in the bottom of the journal box, the ends of the reservoir being closed, a wide wick secured to the upper surface of the yieldable body portion throughout the length thereof, and adapted to contact with the journal, said wick being disposed within said openings and delivering lubribottom of said journal box, said body portion I having a recess formed in the bottom thereof.
cating material to the journal, the ends of the wick being extended into the reservoir through which lubricating material is fed to the upper portion of the wick, by capillary attraction, and ribs secured within the body portion and disposed longitudinally thereof, holding the body portion against displacement.
