LEONARD Gr. WOODS, 0F PITTSBURGH, PENNSYLVANIA.

JOURNAL-BOX.

Application filed December 19, 1910.

To all whom t may concern.'

Be it known that I, LEONARD Gr. WooDs, a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have 1nventeda new and useful Improvement in Journal-Boxes; and I do hereby declare the following to be a full, clear, andexact description thereof.

My invention relates to railway journal boxes. Its object is to provide a form or construction of box which may be manufactured of cast metal, such as cast steel or cast iron and whichis both light and capable of resisting excessive stresses in tra'ic when used with carsof large capacity.

I am aware that journalboxes have been constructed of malleable iron with thin sides, and also that pressed steel boxes are made with corrugations extending down the sides. My invention contemplates, however, a construction of box in which it is feasible to provide very thin side and bottom walls, and which is at the same time so braced by fa preferred arrangement of beads or ribs that it will have the requisite stiffness to withstand the heavy jars and shocks incident to use in modern railroad and street railway traffic. l

While my invention is yapplicable to journalboxes for use with all types of cars or trucks, it is especially valuable fin connection with railroad ycars of great capacity in which it is necessary to brace the box in the region receiving the greatest strains. By my invention I also aim to provide a construction of journal box which may be made of cast steeland still have very thin walls, the bracing beads or ribs forming in casting, runner portions of the cavity in the mold; so that premature chilling of the metal is prevented and a satisfactory pereentage of commercial castings is secured.

rIo these ends my invention contemplates,

-generally stated, a cast metal journal box having thin side and bottom wall portions and an integral bracingY rib or bead extending continuously around the box in its central portion or region of greatest strain,

" preferably two or more of such beads being employed.

serial No. 597,971.

My invention also contemplates the employment of a series of bracing ribs extending around the journal box body at intervals fromits front to its rear end.

My invention also consists in yproviding in combination with the bracing beads, above referred to, a bracing rib extending longitudinally of the bottom wall of the box and bracing beads or ribs arranged to stiffen the front wall thereof beneath the lid opening; and also includes preferably a bracingvbead on the rear wall preferably extending around the opening for the axle as well as other features of construction, as vhereinafter more particularly pointed out and claimed.

By the term rib as used in the accom'- panying claims I mean to include a bead or swelling enlargement of an equivalent nature as distinguished from a mere corruga tion. A journal box of pressed metal having pressed interior corrugations is to be distinguished from my construction n which the continuity of the outer wall surface directly outside of an internal bead or rib is preserved, the total thickness of the wall being thus greatly increased at the bracing rib.

In the drawings illustrating my invention, Figure l is a longitudinal vertical section parallel to the axle (not illustrated) showing one form of my invention. Fig. 2

'is a horizontal section of the same on line metal integral with the side walls 2 andl provided preferably with transverse ribs. 5 to brace it at the point yof greatest strain. It will be understood that .the truck arch bars or pedestal guides grip the box about the mid portion or region of the transverse ribs 5, 5 of the top 4. The wedge guides 6 extend downwardly in this portion of the boxy and serve to further strengthen it as well as to position the wedge and bearing (not illustratedfi.

The front wall 7 of the box is usually of cylindrical form, its axis being at right angles to the axis of the cylindrical or otherwise curved bottom wall 3. Above the front wall 7 is situated the opening 8 which isv normally closed by the lid (not illustrated).

The dust guard pocket 9 is situated between the back walls 10, 11 of the box, which may be of usual or any desired form, 'although my invention permits of a thinner wall 11/v on account of the braced construction of the box in general, and the bead 17, extending around the journal opening 8.

The main bracing ribs 13 are integral wit-h 'the side walls 2 and bottom walls 3 point of greatest strain, the opposite wall surface being continued in its contour, and not being dipped or depressed to form a corrugation such as those employed in some types of pressed metal boxes. As these ribs or beads carry the main portion of the load, it is obvious that their weight should be considerable, and also that any increase therein not only strengthens the box, but renders its manufacture of cast metal easier.

The ribs or beads 15 extend preferably diagonally ofthe box along the lines of intersection of the front wall 7 and the bo-ttom 3 to intersect at the point 16 The said ribs 15 preferably taper off in an upward and forward direction so that they become, when their upper extremities reach the top of the front wall 7, if desired, large fillets. The ribs 15 may, however, obviously be cast of any desired thickness so as to brace the -front portion of the box.

The longitudinal rib 18 extends preferably internally along the bottom portion 3 to meet the ribs 15 at their point of intersection 16. The rib 18 is of the same character as the ribs 18 and completes a truss of basket rib construction, which forms in eifect the load carrying frame of the box, comprising the transverse ribs 13, the intersec'ting longitudinal rib 18 and the di- -agonal or upwardly extending ribs 15. By

increasing the size ofrsaid ribs the box is not only strengthened but the possible thinness of the wall portion proper is increased, as in making the casting the cavities in the molds which provide for the ribs at the same time provide runners or channels to facilitate the distribution of the molten metal.

The ournal box bolts 19 illustrated in Fig. 2 are of usual construction, being situated on the outside of the side walls 2 opposite to the wedge guide 6 andextending from the bottom lug 14 to the top 4 of the box Vbeing illustrated as seated within the journal box bolt depressions or corrugations 19A 'preferably employed.

Fig. 4 illustrates a modification in which the longitudinal rib 20 and forward diagonal ribs 21 are in all respects similar to the vribs 18 and 15 respectively, described above.

The transverse bracing rib construction'is here shown in the form of a series of swellings or ribs 22 which extend around the bottom portion of the box 23 and up itsr side walls 24. The number of such ribs employed is sufiicient to effectively brac'e'the box from its front to itsrear end.' This construction is especially adaptable to boxes for use with railroad cars employing trucks of the pedestal type,'the box illust-rated in Fig. 4 having guides 25 suitable vfor use with the jaws of a pedestal truck frame. The swellings or ribs 22 not only leffectively brace the box, but also greatly facilitate the 'flow of molten metal inY casting.

What I claim is:

1 A journal box having integral side and bottom walls of thin metal, wedge guides extending inwardly from said side walls, and an inwardly extending box bolt corrugation arranged in each side wall, and internally thickened integral bracing ribs extending continuously across said side and bottom walls and connecting'said wedge guides to brace the box in the region of greatest strain.

2. A cast metal journal box having side lverse integral ribs in its top portion, t-hin yside walls and wedge guides integral therewith and extending downwardly to brace the same, a bottom wall of thin metal integral with the side walls, anda pair Vof continuous ribs of thickened metal extending across said side and bottom walls and connecting the wedge guides to `brace the box in the region of greatest strain.

`and bottom walls of thinZmetal, and a top 4. An integral cast metal journal box ing of thin metal integral with said truss having transversely extending ribs in its framework. 10 top portion, wedge guides depending there- In testimony whereof, I the said LEON- from, and continuous connecting ribs ex- ARD G. WooDs have hereunto set my hand. tending downwardly from said wedge LEONARD Gr. WOODS. guides and across the bottom portion of the Witnesses:
