- use on passenger cars, locomotives, freight cars or other type of vehicles, and more particularly to the type of journal box known as the pedestal type.

In this'type of journal box it has been customary to provide vertical guideways to engage the pedestals of the trucks so as to permit a certain amount of up and down movement between the pedestals and the.

journal boxes, to provide easier riding. Of course, this up and down movement causes wearin both pedestal and box and. in the past various ways have been devised to decrease this wear. r

One of the methods used to decrease the wear has been to make the guideways of hard metal inserts; Another method has been to provide the guideways' with removable liners attached to the journalboxes so that when these liners are worn out they may be removed and new ones applied. However,

neither of these methods has been very satisfactory because, when the hard metal inserts are used it is only a question of time before they will be worn out, and then the box will have to be replaced. When the removable liners are employed these are soon worn out and then the trucks must be removed from under the car while new liners are put in place. Of course, the wear on the pedestals continues in spite of either of the above methods of solving the problem. Any such method as outlined above is objectionable because it calls for taking the car or locomotive out of service and the material and labor necessary to remove the trucks from under the car, replace the journal boxes or liners, and replace the truck under the car is great. Y

The primary object of my invention is to provide a journal box, particularly one for use with the pedestal .type of truck, which will be self lubricating, thereby avoiding all necessity for special inserts or liners, and providing a journal box which will greatly outwear any now known.

Another object of my invention is to provide a self lubricating journal box which may be easily made without any'complioated or inexpensivechange in-the presentform of journal b'ox. Inother words, my invention may be embodied in ajournal box-of-wellknown construction, withoutmaterially in creasing the cost of making the same.

In'the drawings forming a part of the specification in which Ihave shown a preferred embodiment-of my invention,

Referring now proved journal box is designated generally by the numeral 1 and is shown-in Fig. 1

supporting a pedestal 2 of atru'ck 3 of well-known type. The pedestal comprises members 2 which are designed to slide within the guideways 30f thejournal box 1, as is well-known in the art;

The journal box is provided with a front 4, having an opening closed by a cover 5. The guideways 3 are formed in the sides 6 and 7 respectively,

e5 Fig; 1 is' anelevation of a portion of a partly in horizontal section, of my improved i to the drawings, 1 my 1m Intermediate the ends of the sides and 7 there are provided inside lugs 8 which act as stops for the journal bearings and wedges, as is well-known in the art. It is common to make journal boxes of malleable cast iron, and in order to eliminate shrinkage cracks in the castings, due to unequal thickness ofthewalls, the sides 6 and 7 are usuallyrecessed at the lugs 8 so as to maintain the thickness of the sides constant. The result is the recesses 9 which form a three-walled pocket in the sides 6 and 7. The guideways 3 are formed on either side of these pockets by projecting flanges 10.

I make use of the recesses 9-for oil pockets or wells, completin them by cast ng integrally with the sldes 6 and 7 a fourth wall 11, and this oil pocket I pack with waste saturated with lubricating oil. It will be noted that the walls 11 project slightly from the sides 6 and 7 to provide sides 11 to co-operate with the projecting flanges 10 to form the guideways 3.

To permit the oil from the pocket 9 to reach the guideways 3 I provide openings 12 in the portions 11 through which the oil may flow to the guideways and into grooves 18 provided in the faces of the guideways. These grooves may be omitted, if desired, but in practice I have found that they are satisfactory asv a means toena'ble the oil to readily spread ut over the err-- tire width of the guideways and eifectively lubricate the wearing surface of; both the journal. box, and. pedestal during the up anddown movement of} the truck. These grooves-are: shallow: and I have showrrthem arnanged iina,zignagfashion, and arranged,

any type of truck where it is applicable.

It willv be-seen that my improved; journal box. maybe made from a single casting by a modification of a Standard journal, box which modification may be easily and in.- expensivelymada The result is a; self In,-

bricating journalzbox which has been found, in actual pract ce, to avoid any substantialwear' upon either journalbox; or; truck, and which has been found to be most efficient in operation, avoiding troublesome replacing of journal boxes or liners.

I am aware that changes in the form, construction and arrangement of parts may be made without departing from the spirit and without sacrificing the advantages of the invention and I reserve the right to make all such. changes as fairly fall within the scope of the following claims.
