ALBERT 0. 'BUCKIUS, JE., IOF CHICAGO, ILLINOIS, ASSIGNOR TO THE NATIONAL 'MALLEABLEOASTINGS COMPANY, OF CLEVELAND, 01-110, A CORPORATION OF'OI-IIO.

MANUFACTURE OF JOURNAII-BOXES.

Application filed July 23,1919.

To all whom it may concern Be it known that I, ALBERT O. BUCKIUS, Jr., a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented new and useful Improvements in the Manufacture of Journal-Boxes, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is an end elevationpartly in section showing the application of my invention to a journal box; Fig. 2 is a plan thereof, partly in section; and Fig. 3 is a side elevation thereof.

My invention relates to the manufacture of journal boxes and particularly to casting of inserts or wearing plates in the pedestal guides of journal boxes' I have found it desirable, especially where boxes made of malleable iron are employed, to apply the wear plates in the pedestal guides of the lzoxes after the malleableizing process has been completed. To this end I apply molds about the pedestal guides of the boxes and cast the wearing plates or inserts therein after the box has otherwise been finished. ly invention also consists in the features which I shall hereinafter describe and claim. 7

Referring to the drawings, 2 indicates the journal box pedestal guide flanges which preferably have machined faces so as to bring the distance between opposite flanges to a correct dimension. The mold 3 fits against the faces of the flanges 2 and has a projection 4 which extends between the flanges 2 leaving a space or cavity 5 conforming to the shape of an insert which is to be poured therein. The mold 3 also has portions 6 which overlap the top and bottom of the box respectively and comprise a closure over the upper and lower ends of the guides. Upon the top of each mold 3 is placed a mold section 7 which is provided with a pouring cup 8 and a pair of vents or risers 9. Where, as shown, the journal box is provided with two pedestal guides, gates 10 connect the pouring cup 8 with the cavities 5.

The molds 3 are secured to the journal boxes by clamps 11 which are provided at.

their outer ends with a bearing member 12, secured to the clamp by a cam arrangement 13 which allows the member 12 to tip slightly to accommodate itself to the outer Specifwation of Letters Patent.

face of the mold 3. The inner end of the clamp 11 extends through the dust guard opening in the rear of the box and bears directly on an inner surface 14 thereof.

When the molds are poured, the cavities 5 are filled with metal and form plates in the pedestal guides which interlock with the metal of the box in the recesses 15. If desired, ribs 16 may also be provided between the flanges to effect a more complete anchorin of the insert in the guide.

I3y casting gray iron inserts as described in the pedestal guides of a journal box, I have found that a superior product is obtained in which the inserts adhere properly to the box and present straight and very durable wearing surfaces engaging the truck pedestals.

The. terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described, but recognize that various modifications embodying the substance of the invention are possible with in the scope of the invention claimed.

\Vhat I claim is: i

1. Apparatus for casting a metallic insert in pedestal guides on the opposite sides of journal boxes, comprising a mold section forming with each pedestal guide a closed cavity conforming to the shape of the insert to be poured, the faces of the pedestal guide ribs being accurately spaced and machined so that the over all dimension of the inserts will always be the same regardless of variations in the other parts of the box, and a clamp for securing the mold section against the machined faces of the guide ribs during the pouring operation.

2. A mold for forming inserts in the pedestal guides on the opposite sides of an annealed journal box, comprising mold sections, accurately spaced and dimensioned surfaces on the opposite sides of the box against which a mold section is held to form with the box recesses for a plurality of inserts, and additional mold sections providing pouring cups and forming with each of the mold sections passages from said pouring cups to the said recesses.

3. Apparatus for forming metallic inserts in the pedestal guides of a journal box, comprising a journal box having pedestal guide ribs standard distances apart, mold sections secured against said guide ribs and against the top-and bottom of the pedestal guides, but spaced apart from the faces of the box between the guide ribs, the said spaces inclosed by the said box andmolds corresponding to the form of an insert.

4. The process of casting metallic inserts in the pedestal guides of a journal box,

10 Wl1lCh comprises forming the pedestal guide ribs of the box with their outer faces on opposite sides of the box a standard distance apart, securing molds against said faces, said molds being spaced from the other Vertical faces of the guides, and pouring metal into the spaces thus defined between the guides and molds, thereby forming inserts in the pedestal guides,
