AUGUST G. SANDMAN, OF BALTIMORE, MARYLAND.

JOURNAL BOX.

Application filed August 2,

To all whom it may co'nccm:

Be it known that I, AUcUs'r G. SANDMAN, a citizen ofthe United States, residing at' Baltimore, in the State of Maryland,- have invented certain newand useful Improvements in Journal Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as 'will enable others skilled in the art to which it appertains to make and use the same.

y invention relates. to journal boxes and, generally stated, involves the provision of a renewable wear "plate or liner detachably connected to the journal box of a railway car for preventing destructive wear upon the car truck pedestal jaws and journal box associated therewith.

The principal feature of the present invention, particularly stated, resides in the production of a journal box having tapered pedestal guide ways, and associating therewith a liner or wear plate adapted to fit within the tapered guide ways.

Another feature of the invention consists in tapering the wear plate or liner laterally of the journal box from a lesser width near the center to a slightly greater width at the top and bottom thereof, whereby said journal box can move laterally in the pedestal ways said movement involving in addition to the relative vertical movement of the journal box pedestal jaws, a relative rocking or pivotal movement f said journal box and pedestal incident to axle thrusts and the like.

Another feature of the invention is to provide a flanged liner for journal boxes for pedestal trucks, the flanged port-ion of said liner being tapered to eflectively retain the liner in engagement with the journal box and provide lateral clearance for pivotal movement of said journal box with respect to the pedestal jaws.

A further feature of the invention consists in combination, a journal box having a reservoir adapted to receive a lubricant such as oil, a wear plate or liner adapted to be connected to said journal box for permittin relative pivotal movement between the pe estal jaws and the journal box, and means for establishing communication between the oil reservoir and the wearing surface of the liner whereby lubricant is permitted to flow to said wearing surface.

The invention further consists in the pro- 1922. Serial in. 579,263.

vision of a journal box renewable pedestal way flanged liner which can be inexpensively manufactured and easily attached to a journal box adjacent an oiling cavity preferably in the top of said journal box. There are other features of the invention as will more clearly appear from the detailed description taken in connection with the accompanying drawings in which Figure 1 is a view in side elevation of a railway car journal box showing my improved wear plate or liner applied.

Figure 2 is a vertical detail sectional view on the line 2-2 of Figure 1 through a portion of the journal box and oil reservoir at the top thereof.

Figure 3 isa' detail horizontal sectional view on the line 3-3 of Figure 1 showin the flanged liner cooperatively associated with opposite faces of the. journal box flanges.

Figure 4 is a detail central vertical transverse sectional view through the upper portion of the journal box illustrating the oil reservoirs and the attaching tongues of the liner engaging the walls of the reservoirs.

Referring to the drawings in which similar reference characters designate corresponding parts in the several views, the railway car journal box is indicated by the nu meral 1, said journal box being provided with the top wall 2 in which is formed the seat 3 adapted to receive the cushioning element, and the usual bottom wall 4. The opposite side walls 5-5 of the journal box are each provided with projecting adjacent ribs or flanges 6', each of which is tapered laterally of the'journal box so as to provide a lesser width between the flanges at or near the center thereof, than between said flanges at the top and bottom edges. The tapering flanges 6 and side wall portions of the journal box are formed with a guide way in which is provided a clearance between the pedestal jaws and the journal box flange, said clearance permitting relative pivotal or rocking movement between the journal box and pedestal. The inner opposed facesof adjacent flanges 6 are inclined from the top and bottom edges thereof respectively, toward the center, portions of said flanges extending out into the pedestal guide ways to form extensions in the nature of fulcrum points 7 A flanged wear plate 8 is adapted to fit within and line said pedestal guide wa the flanges 9 thereof being tapered to t the tapered portions of the flanges 6 formed on the journal box. The liner, and more particularly the flanges 9 thereof, is taered or inclined laterally of the journal box from a lesser width near the center to a slightly greater width at the top and also at the bottom thereof, the taper or incline of said flanges corresponding to the tapered portions of the journal box side wall flanges 6 with which latter the flanges 9 of the liner engage.

The web or body portion 10 of'the wear plate is arranged to engage the side wall 7 portion of the journal box adjacent the projecting flanges 6, as clearly shown in Figure 3. The wearing surface of the web portion and adjacent flanges 9 are lubricated by means of oil or other lubricant, .said lubricant being contained within a reservoir or cavity 11 preferably at the top of the journal box, an upstanding surrounding wall portion 12 serving to retain the oil. In the form of journal box shown I have provided a plurality of oil reservoirs, one on each side of the cushioning element seat, as shown, although it will be understood that a single reservoir may be used in some constructions.

Provided near the bottom of each reservoir is an opening 13, said opening being adapted to communicate with an opening 1a formed in the web portion of the wear plate, audit is through these registering openings that the oil or lubricant is conveyed to the wearin surface of the liner. Each opening 14:: in t e wear plate is preferably provided near the top thereof and adjacent the oil reservoir w as'to provide for the gravitation of the oil over the wearing surface of the liner. The wear plate is shown as formed with two openings, each of said openings, each of said openings being located relatively close to the adjacentflange 9 of the liner. In the type of journal box shown the liner is cut away intermediate said openings, as indicated by the numeral 15, so as to fit the journal box side wall beneath the oflset portion therein provided for the clearance of the equalizer bar, not shown.

The means for detachabl connecting the wear plate to the journal ox includes up--- extensions 17 are formed on the lower edge of the liner, said extensions forming tongues or tangs ada ted to be bent around the lower edge of the ournal box side wall, as shown. Other types of attaching meansrnay be utilized, as will" be understood. It will be the liner in engagement with the journal box, thereby supp ementing the upper and lower connecting tangs.

From the foregoing description it will be H apparent that T have provided a journal box having a tapered pedestal guide way adapted to be lined with a tapered flanged wear plate whereby relative rocking movement incident to service conditions can be eflectively permitted, and which, together with the adjacent means for lubricating, the wearing surface of said wearplate, serves tomaterially reduce the strain and wear and increase the longevity of use of the associated parts.
