CAR JOU RNAL-BOX.

SPECIFICATION forming part of Letters IPatent No. 36,355, dated September 16, 1890'.

Application filed DeoemberS, 1839. Serial No. 334,201. (No model) To all whom it may concern.-

Be it known that I, EDWARD WILLIAM MACKENZIE-HUGHES, of Ohicago.0ook county, State of Illinois,-have invented a new and useful Improvement in Car Jour11all3oxes,of which the following is a full, true, and exact description, reference being had to the accompanying drawings. 7

This invention relates to an improvement in journal-boxes for cars, made of pressed steel and with but a single joint or weld. Heretofore journal-boxes have generally been made of cast metal, or when made of steel have required several weldings. My journalbox is made of a single piece of metal pressed and shaped as will be hereinafter described.

My invention will be readily understood from the accompanying drawings, in which Figure 1 represents a cross-section through the metal plate to be shaped; Fig. 2, an elevation of the box shaped by the first process; Fig. 3, a perspective view of the box when completely bent and welded; Fig. 4, a perspective view of the strengthening crownpiece; Fig. 5, a cross-section through the completed box, showing the crown-piece in position; and Fig. 6, a general view of the blank from which the box is pressed.

In forming my box I take a sheet of steel having approximately the cross-section as shown in Fig. 1, which may be out by a die or otherwise to the general shape shown in Fig. 6. rolled continuously and afterward out off to the proper lengths, if desired. The sheet shown in Fig. 6 is then bent hot, preferably by the Fox process of pressing steel as, for instance, that patented to Samson Fox on the 5th day of February, 1889, No. 397,179

The section shown in Fig. 1 may be into the shape shown in Fig. 2, the ofiset K forming the part K shown in Fig. 2. The upper edges of the box are then pressed over a former and butt-welded, as shown in Fig. 3. I prefer to do this welding by electricity. I prefer to strengthen the upper part of the box by the crown-piece E, having ears F F, which may be welded in or riveted, as desired. I finish the box by cutting the slot G by an'ernery-wheel or otherwise. The exterior flanges O D strengthen the box, and the u described.

A journal-box for cars, formed of a continuous piece of pressed steel, and having flanges surrounding the same pressed from part of the metal of the box, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
