As shown the journal box is indicated at [5 and the journal at It having a collar [1 and fillet It. A usual form of dust guard is indicated at I!) housed in aslot 20 at the rear of the journal box, the opening the fjournal box at -2I being of sufiicient size to passthe collar l1 in'theusualmanner. 1 v

I As shown,'-the lubricator comprises separate felt elements -2-2, shown i nelevat'ion, in Figure 2 and in perspective in Figure 4,, the elements formed ar'cu'eite at their surfaces 23 to substan tiallj fit the journal and having

Wick elements

24, 25, 2B projeetiiig downwardly from their bodies 21. To hold the arms of the bodies 21 in proper relation to the journal even when soaked with 'o'il, thereare shown spring wires 28 fastened to the bodies}? as by stiching 29 A To press the lubricate! elements 2? against the journal springs SiL'one being shown as supplied for each element 22, are shown reacting between thebodies 21 and the bottom of the journal box. The wick elements 24 are surrounded by the springs 30 as shown and thewicks 25 and 26' extend downwardl'y'irom the bodies 21 exterior of the springs whereby they are not subject to any compression or any action'of the springs which would interrere withtheir porosity and capillaritv -'Io preserve the elements 2; in vertical, latof its element 22 into the socket provided by the adjacent bushing 31. A

-To" hold the fro'nt' end of the-assembled lubrica'tdr in locationlaterally and circumferentially, while permitting vertical motion in response to the relative motion between the journal box and the journal, there is shown a bolt 36 engaged'in an opening in the front of the journal box-and secured therein by nuts '31 and lock nuts 38, the bolt having a plate 39' provided with a hinge member :40 acting with ahinge member H carried upon a fitting 52 shown in perspective in Figure: 5; The opening 43' in the fitting 42 is rectangular in cross section and the flattened rod '32 projecting iromthe front element 32 and deflected downwardly as shownat 44 to clear the collar 11 enters the opening 43 and thereby prevents twisting of the front end of the lubricator.

To prevent twisting of the rear end of the 111- bri'ca'to'r', thfere is shown a piece of rod of the same charaote'r as 32, 32" indicated at 45; which has its rear end turned downwardly'to a portion 46 secured to the U-iron d'l which may be in th form shown 'in Figures 1, 2, and 3, or that shown in Figures 11, 12, or 13.

The U-iron 41 is shown as provided with projections 48 from which portions may be ground in order to fit the U-iron to the interior of journal boxes of slightly different width so that the iron may move vertically with slight movements of the journal box relative to the journal. To hold the U-iron in place while the first element 22 is being assembled therewith, a socket 49 is shown as provided upon the edge of at least one of the arms which may be engaged by a hook to place the iron in position.

Considerable difiiculty has been encountered with an excess of oil escaping at the rear of the box as by splashing, when a lubricator of the present type is used, where there is a body of oil subject to such action. To' prevent this there is shown a splash guard 50 carried by the U-iron and preferably made of flexible synthetic rubber. In many cases the simple flap of flexible material will be sufficient but if it is found that there is still too much escape of oil, an additional rib i may be supplied upon the upper edge of the flap 50 of a proper vertical dimension to pass through the opening 2| into contact with the dust guard I9.

When the journal box l5 is jacked up for renewal of the brasses the springs 30 will be compressed, the fitting 42 will move about its hinge member and the upper edge of the flap 50 will contact with the fillet l8 of the journal which will result in deflection of the flap inwardly along the surface of the fillet.

To press the flap rearwardly into sealing position there is shown in Figure l a spring member 52 secured to the U-iron with its upper end inturned so as to yield inwardly when the journal box is jacked up but which normally presses against the flap 50. A similar member 53 is shown below the U-iron acting in a like manner for the lower portion of the flap.

An alternative structure for this purpose is indicated in Figure 6 where there are shown coiled springs 54, 55, which may be anchored to the arms of the U-iron and being stretched into position will yield inwardly with deflection of the flap but will normally be tensed to straight position by the anchors to hold the fiap in operative position.

In the form of Figure 6 a solid rod 56 is substituted for the sectional rod shown in Figure 1. The U-iron 41 is provided with a socket 51 to be engaged by a downwardly projecting terminus 58 of the rod 56, the front end of the rod entering a socket in the fitting member 42' as in the form of the device already described.

To prevent the installation of the rod 56 in inverted position, the socket 51 is shown as formed with a rib 59 and the terminus 58 with a groove 60 to match. In order to prevent the rod 56 from being inserted in the socket 51 wrong end to, the socket 51 and the terminus 58 are made of less width than the body of the rod 56.

The felt elements 22' to be used with this form of the device are similar to those of the form of Figure l but have plain bushings only extending therethrough.

To prevent rod 56 from coming into contact with the journal when moved abnormally, the end elements 22' as shown in Figure 6 are recessed at 6|, 62 respectively to project over the metal. The length of life of the lubricator will be determined by the wear of the felt elements and if they can be worn nearer to the surface of the rod 56 their life will be longer than would otherwise be the case. To give additional term of life the front end of the rod 56 is shown as thinned away at 63 through the portion which enters the socket of the fitting 42.

In the form of Figures '1 and 9 a socket member 64 is shown as secured to the rear wall of the box and a section of rod 65 formed with a downturned end 66 to enter the socket. In order that the wrong end of the section 65 may not be inserted into the socket, lugs 61 are shown formed upon the downturned end 66 entering grooves 68 in the socket. To prevent the rod 65 from escaping from the socket during abnormal movement, the upper edge of one groove 68 may be deflected inwardly as at 69 after the rod 65 is in place.

To enable the U-iron to be used with journal boxes of different sizes without excessive or even any grinding away of the projections 48, the U iron may be made expansible. In the form of Figure 11 the iron is shown as divided longitudinally into overlapping parts 10, 1| hinged together as at 12 and pressed outwardly by means of a fiat spring 13 secured at 14 to the main portion of the U-iron and pressing at its upper end against the member 10 to urge the same outwardly in the box. Two sockets 49 are shown upon this form of the U-iron which may be engaged by two tool hooks to hold the U-iron somewhat collapsed While it is being inserted after which it will be pressed outwardly by means of spring 13.

A further form of U-iron may have one of its arms adjusted relative to the other thereof as indicated in Figure 12 where two overlapping

parts

15, 16 are serrated at their meeting portions and clamped together by clamp bolts 11 when adjusted to the size required.

In Figure 13 an expansible U-iron is shown comprising one arm 18 hinged at 19 to the remainder of the iron and held in outward adjusted position by spring brace member BIJ'rigid- 1y secured at 8| to the hinged leg and co-acting with teeth 82 carried by the iron.

Figure 14 shows a form of spring to press the sealing flap to position comprising spring fingers 83, 84 secured to the bushing of the rear felt element 22. Secured to the U-iron 41 is shown a rod section 85 entering the bushing 3| and thus supporting the U-iron in position.

In Figure 15 is shown a fiat rod 56' of the form of Figure 6 but shorter and combined with a section of rod 32' carried by the outer element 22 coacting with the socket 42". The section of rod 32' is shown as downwardly off-- set and hence no part of it will contact the journal before the felt is completely worn down to the bushing. This form of the device cannot be installed wrong by unskilled labor.

Also in this form of the device the sealing flap 50' is extended to engage tie bottom of the box at 85. At times the U-iron is found to tilt forwardly in the box during movements of the box which allows the sealing flap to leave position. To prevent this there is shown in this figure a leaf spring 86 pressed by the U-iron and having a loop at its end bearing upon a wear-resisting rivet 61 carried by the flap.

A form of sealing flap carried by the dustguard 88 is shown in Figure 16 comprising a flap, as of rubber, riveted to the dustguard and retained in sealing position by a spring member 89.

The splash guard 50 of Figures 17 and 18 is shown as secured to the journal box structure. As shown a metal angle 90 is placed against the guard and cap screws 9! are passed through the angle and guard to enter screwthreaded openings in the wall of the dust guard channel. The angle may be welded in place or cast integral with the box and the splash guard slipped into the thus provided channel. In the event that it is desired to space the splash guard forwardly from the fillet of the axle a pair of such angles may be provided secured to the bottom and sides of the box or a pair of spaced ribs cast integral therewith to provide a splash guard receiving channel.

Tohold the splash guard in position, there is shown in these figures a coilspring 52' anchoredat its ends to the angle 90 under considerable tension. This spring may be secured between its ends to the splash guard in any desired manner, as shown by hasps 92. To give added clearance of the spring from the axle, the center of the spring is shown as tied down by a flexible member 93 anchored at 94 to the angle 90. When the box is jacked up to change brasses the guard and spring will yield, to be returned to normal position by the tension of the spring when the jack is removed.

As illustrated in Fig. 19 the felt elements are cut from the sheet in the relative positions as shown, to save material. To effect afurther saving the journal contacting surface is cut on a curve or less radius than that to be fitted. For instance for a inch journal the curve might be cut on an arc of a 4% inch circle. The wire 28 will be initially contracted more than desired in order that when contracted and attached to the felt it shall spread the felt to approximately the 5% inch circle.

Minor changes may be made in the physical embodiments of the invention within the scope of the appended claims without departing from the spirit thereof.
