journal, due to the fact that the vibration to which thejournal boxes are subjected causes the waste to settle andpack, thereby=leaving a space between the waste and the ournal. Furthermore, difliculty is OftBII- BXPGIlGIICGd with what is commonly termed waste grab, that is, portions of the waste'get in between the journal and its bearing. a This condit on is usually brought about by the bearingbeing lifted from its journal, due to severeshocks' caused by emergency application of'the car brakes or sudden stops from any cause.-

These'conditions, namely, first, the journal and waste not being in. contact and,second,

portions of the waste getting-in between the bearing and journal cause the bearing to heat inducing what; is commonly known as a hot b0x a The primary objects ofmy invention are, therefore, to provide simpleand reliable means for holding the waste in. contact with the journal and in preventing'circumferential movement of the waste.

A primary feature :of the invention consists inassociating with the journal box a pair of pivotally mounted members, each of which is provided with a plurality'of fingers for maintaining 40 withthe-journal. 7

Another feature of the invention consists in providing the interior surface of the jour-f nal box with arcplurality of recesses respec tively adapted to receivethe fingersof. the

waste cooperating members so that whenthe latter are in inoperative positions the lower inner surface of the box will be practically free of projections or protuberances to permit the waste to be easily and conveniently in serted into and withdrawn, from the box;

the waste in proper contact 7 center of. the

' ,Still another feature ofthe invention con sists in combining with'the waste cooperat ing members spring means normally urging themember's in a direction so'as to maintain the waste in engagement with the journal.

Other and more specific features of the invention "residingin; advantageous forms, combinations and relationsof parts will hereinafter' appear and be pointed out in the claims. q r

Referringmore particularly to the drawindicates the journal box, only the" lower half beingillustrated as'the construc- I tion of the upper half ofthe box, since it forms no part ofthe invention, may*be of any usual or desired construction. The major portion of the lower half of the interior sur faceof'the box issemi cylindrical in section,- the -'center of curvature thereof beingfpreferably-disposed in the same vertical planeas the center of the journal 2. As is usual in', journal box construction the rear wall or walls 3thereofare suitably apertured asat; 4 to receive the j ournal'anclthe opposite-wall is formed withan opening5 normally closed by alid (not-shown). y i Pivotally mounted within the box is a pair of members 6, each of which comprises a main rod or shaft 7 and a plurality of spaced arms orfingers 8'. The members'fi :are=respectively disposed on opposite sides'of-the V ournal and are preferably mounted adjacent the side walls 'ofthebox."

P TE TOF E I The inner ends of the shafts 7 are respectively journaled in openings 9 formed in the rear wall 3 of the box. Surrounding these apertures the rear wall may advantageously be formed with inwardly projecting bosses 9a and in order to prevent longitudinal movement of the members 6 toward the rear wall 3 the portions of the shafts cooperating with the apertures are preferably reduced to form a shoulder 10.

To support the outer ends of the shafts 7 the side walls of the box may be conveniently integrally formed with inwardly projecting lugs or brackets 11.. Each of the brackets is substantially U-shape in cross section and is provided with an end wall 12 to prevent the associated shaft 7 from movinglongitudia nally in a direction toward the front wall of the box. The shafts 7 may be retained in their respective brackets 11 by any suitable means such as screws 13 respectively adapted to overlie the shafts thereby preventing their unintentional or accidental upward movement.

The waste cooperating fingers 8 are preferably formed integral with their shafts 7 and while any number of the fingers may be used it has beenfound that three will sufficiently and adequately perform their intended function. The fingers are preferably shaped so as to conform to the contour of,

adjacent portions of the interior of the box and since, as has already been stated, the

interior surface of the boxadj acent the lower portion is semi-cylindrical the fingers are curved, their center of curvature being coincident with that of the curved inner surface of the box. The interior of the box is formed with a plurality of recesses or de-.

pressed portions 14 for receiving and hous-' ing-the fingers 8 so that when they are in inoperative position their outer surfaces will be flush with adjacent portions of the inner surface of the box. Thus it will be perceived that the lower portion of the inner surface of the box is free from projections andprotuberancesthereby permitting the ready insertion of Waste into the box.

bodiment of the invention this means consists iently formed integral with the associated shaft'7, a spring 16 and mechanism for vary-i ing the force exerted by the spring on the Associated with each'of the members 6 is a means for exerting suflicient pressure on the oil waste to maintain it in proper contact with the journal and for preventing displacement of the waste. In the'present emof 3. depending arm 15 which maybe convenarm 15. As the arms 15'are disposed substantially vertically when the members6 are in inoperative positions the' box is formed With cavities or recesses 17 for receiving or housing the arms 15. 3

Whil'e the spring 16 and its associated arm 15 -may be operatively connected in any de- -formed with a head, such as a hexagonal nutlike portion 21 for cooperating with a wrench or the like, which may be employed for rotating the sleeves in the desired direction. The end of thecoil spring 16 opposite to the end attached to the arm 15 is disposedwithin the sleeve 20 and abuts against its closed end. It will thus be perceived that by rotating the sleeves to cause them to move inwardly force is transmittedto the arms 15 through the intermediacy of the coil springs 16 whereby the shafts 7 are rotated in a direction to move the fingers 8 upwardly. Any suitable means such as a lock nut 22 may be employed for maintaining the sleeve 20 in a desired position of adjustment.

The manner of associating and disassociating the members .6 with the ournal will, of course, .bereadily appreciated. When the parts are in the position as indicated in Figure land it is desired to remove them from the box, the members 6 are rotated by hand to withdraw the coiled springs 16 from their sleeves 20. The screws 13 are then withdrawn from the brackets 11 to permit the outer ends of the members 6 to be elevated, After this is accomplished the inner ends of the shafts 7 may be readily withdrawn from the apertures 9 in the inner wall of the box and the members bodily removed from the box through the opening 5. In assembling,

the members practically the reverse operation is performed,-namely, the members 6 with their coiled springs attached, are inserted into the box through the opening 5, the

Rand-the coil springs 16 inserted in their sleeves 20. I v a After the parts have been also assembled the sleeves 20 are so adjusted that the fingers 8 and the arms 15 of the members may fall by gravity into their respective recesses or housings. T he waste [which has. already been saturated with the required amount of oil may then be inserted in the box. Under present approved methods of packing journal boxes enough waste must be used to fill the space between the underside of the journal and the bottom of the box so that the Figure 1.

waste will be held firmly in contact with the journal. By the use of the present invention, however, smaller quantities of waste may be employed than heretofore considered essential for efliciently lubricating the journal, as the members 6 are operated to support or hold the waste in contact with the ournal. Thusit will be perceived that considerable saving may be eflected by the use of the present invention due to the fact that smaller quantities of waste may be used. Since, the members 6 are operated through the intermediacy ofthe springs 16, the latter will not only constantly exert sufficient force tending to keep the waste in contact with the journal but will also absorb vibrations tending to condense the waste. Although the waste is a comparatively homogeneous mass, due to its inherent resiliency and the fact that the fingers are'spaced a relatively great distance apart, portions of the waste between the fingers will expand or sag downwardly, as shown in dotted lines in Thus portions of the waste will always remain in contact with any oil that may be in the bottom of the box so asto maintain a thread connection between the latter and the journal. Furthermore, since portions of the waste, when the fingers are 1n operative position also extend downwardly between the fingers of both of the mem-' bers, the waste is effectually prevented from movement longitudinally and circumferentially of the journal.
