JOURNAL-BOX.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed February 28, 1918. Serial No. 219,632.

To all whom it may 00mm.-

Be it knownthat I, THOMAS H. WHITE, a citizen of the United States, residing at South Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Journal-Boxes, of which'the following is a specification.

This invention has relation to journal boxes for railway rolling stock and has for an object to provide primarily a journal box adapted to be closed and locked in a manner to prevent removal of lubricant or waste, also brass bearings.

Another object of the invention is to provide a journal box formed with an opening through which waste and lubricant may be introduced, and closed by a screw threaded plug comprising a locking means operable by a key to retain the plug against rotation and consequent removal when once in serted without the use of the key for which the lock is designed.

In addition to the foregoing my invention c-omprehends improvements in the details of construction and arrangement of the correlative parts to be hereinafter more fully described and particularly set forth in the appended claims:

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several'views inwhich they appear Figure 1, is a view in longitudinal section taken through a journal box embody ing my improvement. Fig. 2, is a view thereof in end elevation.

Fig. 3, is a detail view in perspective illustrating a receptacle for holding the weight, and

Fig. 4, is a detail view onan enlarged scale illustrating the locking mechanism. With reference to the drawings, 10 indicatesthe casing of the journal box, and 11 indicates the journal. The brasses 12 are superposed upon the upper surface of the journal in the usual manner. Mounted upon the uppersurface of the brasses is an angular plate including, an attaching portion 13, an upwardly extending portion 14, and a horizontal portion 15 extending toward the outer end of the journal boxand through an opening 16 in the upperplate thereof. -The opening 16 and the angular plateis covered by a movable hood 17 having its frontend open whereby the interior may be viewed. Extending centrally from the end of the journal is a pin 18 to which the lower end of a vertically extending gage rod 19 is pivotally secured. The upper end of the gage rod 19 extend-s through an opening in the horizontal portion 15 of the angular plate and is provided upon its front surface with a series of vertically spaced graduations.

. The front end of the journal box is left open and provided with a plurality of inwardly extending lugs 20 which are apertured to receive bolts. A relatively thick plate 21 is applied to said open end of the journal box and is formed in its body with holes and in its outer surface with countersunk rectangular openings 22 registering therewith and of a size topermit the introduction therein of bolts 23 and to snugly engage the endsyof the bolts to prevent rotation thereof. The threaded portion of the bolts extend through the lugs 20 and nuts 24 are applied to the inner ends of the bolts to bind the plate 21 in place. The bolts 24 may be applied by inserting the hand through a circular internally threaded opening 25 formed in the covering plate 21. It will be obvious that after the bolts 24 are once secured in place they cannot be removed from the outside of the journal box because of the tightly fitting opening 22 which precludes the application of a wrench or other tool to the bolt. The internally threaded opening 25 is closed by a plug 26 having a rectangular extension 27 thereon to permit the application of a wrench thereto. The plug 26 is formed with a recess 28 adjacent the periphery to contain locking mechanism, and a radial opening 29 intersects the recess 28 to guide a. radially movablelooking bolt 30 which may extend beyond the periphery of the plug. The inner end of the locking-bolt 30 is provided with a. rightangul ar extension 31 engagealole by the ward 32 of the key which may be inserted through the keyhole 33. The bolt 30 is formed with a pair of spaced notches 34 in either of which one end of a leaf spring detent 35 may engageto releasably retain the bolt in either a locked or unlocked position.

Disposed. beneath the journal 11 within the journal box, is an elongated receptacle 36, shown in detail. in Fig. 3, and which secured at a point interme iate their ends to the under side of the receptacle whereby opposite ends may extend downward in diverging relation to resiliently support the receptacle and to urge the same against the under side of the journal. The receptacle 36 is filled with waste, and the waste is caused to bear against the under side of the journal to lubricate the same. I employ a novel form of lubricating device which con sists of ar vertical pipe 38 mounted in the rear end ofthe journal box and having its lowerend extended at right an glesas at 39 and disposed adjacent the bottom of the journal box. Thepipe 38 is formed with a horizontal braiieh or extension 4t0'at a point adjacent the journal 11. The 38 extends into the branch 40 through the medium of a lip 41 which extends well into said branch 40 and the branch a0 is furthermore in communication with the horizontal portion 39 as will be readily seen from Fig. 1. The branchlOis provided witha plurality of j'ets 42 which are directed toward the journal, and the upper end of the pipe 38 is connected to avalve casing 43 having a valve l-l located therein and held in nor mally closed position by means of a comparatively heavy spring 45. he valye casing 48 is placed in communication WIT/l1 the brakepipe of the air brake system by means of ahose connection 46 andthe valve 4% is designed to open to permit the entrance of air from the system into the branch 40 when the pressure exceeds the strength of the spring 45 to retain the valve ltclosed. The pipe 38 is of a comparatively small diameter so that very little of the air of tl ie system may be required to supply the lubricant.

In practice, during (the time that the train is in motion, the brake pipe will obviously be supplied with. air at standard brake pipe pressure. It is necessary therefore, when the train is running to i.nsure proper lubrication of the journal, To this end the spring 45 is adjusted so as to open when, the brake pipe pressure reaches its predetermined running point whereby air is forced through the pipe 38 and deflected by the lip 41 into, the branch 4:0 thereby pro ducing an injector efl'ect whereby oil or lubricant is elevated frointhe portion- 39 which is submerged in oil into the branch 40 and directed by the force of air through the jets 42 upon the journal. Excess oil is wiped off the journal by the waste contained in the receptacle 36 and said receptacle may be formed with an opening- .in its bottom to permit the oil todrainbaek into the reservoir. It will be noted that when the train is not runningthe main brakepipe pressure will be, but this is as it should be inasmuch as the necessity for lubrication while the train is not in moti o n is not as imperative.

It will be noted that after the waste is introduced into the journal box and the plug 26 inserted it can be rotated until the plug 30 is broughtto a pointto enter a recess 47 in the wall of the threaded opening 26 i'vh'ereby when the key is rotated to'the left the locking bar may be moved thereinto and the threaded plug thus held against rotation. The theft of waste and lubricant is thus effectually prevented and the loss to railroads from this source, which is considerable, thereby precluded. The condition of the brasses may be observed without opening the journal box, inasmuch as the proximity of any one of the graduations on the vertical gage bar 19 to the lower edge of the portion 15 of theangular plate will indicate the brasses. j

Thus it will be seen that I have provided a journal box embodying many novel features of construction, which is simple in constructioii and whose slight increase in cost of manufacture will be amply compensated by a saving in the loss of lubricant and waste. It will furthermore be seen that the damage to journals and rolling stock would be prevented owing to the method of lubrication which insures lubrication of the journals at a time when the lubrication is most required. Other uses and advantages will be readily apparent to those skilled in the art to which this invention appertains. V

While Ihave illustrated and described my invention with some degree of particularity I realize that in practice various alterations thereover may be made, and I therefore desire to reserve the right and privilege of changing the forn'i of the details of construction and arrangement of the correlative parts without departing from the spirit of the invention or the scope of the appended claims. j p X H v I Having thus described my invention what I claim as new and desire to secure by Letters Patent is j 1.
