nfovzm RAILWAY-GAR- The Schedule referred to lath/ace Letters Patent and makingpart of the To all whom it may concern Be it known that I, OBY RQBIRDS, of St. Louis, in the county of St. Louis, and State of Misssouri, have made certain new and useful Improvements in Axle- Journals and Boxes for-ll-ailrcad-Oars, 'and' similar purposes; and I do hereby declare this to be a full and true description thereof, ref :rirrg to the accent, panying drawirjrgs, and to the letters of reference marked thereon;

It is wellknown that the weight of andfou railroad-cars and similar vehicles of ti-afiicy'is transmitted by properjournal-boxes upon journals of the can; axles, these being secured to the wheels, and as said (for instance, in passing curved portions of the track,) the jounrahboxes then have a"tendency to lateral movement, and to restrain this the journals have collars, the edges whereof project perpendicularly above the journals, and above t bearing-surfirccs of the journal-boxes or the brusscs therein. 4

The collars aforesaid are usually arranged with only a small projecting surface, in order that the wheels the part of the axle within or between tlrejoumrals, and this occasions greatn'ea'r of said' collars, and also of the journal-bones or their brasses, in the usual vibrations and lateral movements due to ordinary movement in running upon railroad-tracks.

The nature ofjhis invention is in the use of a series of slraped collars, between the end collars usually constructed upon car-axles, and in the formation of corresponding inder'itations for said [\rUOllilvlS in the journal-boxes, and int-he manner of r'cinl'orcirn; said portion of the jourrral'irr the nrauncr now who described.

To enable those skilled in these arts to make and use my said improvements, 1 will now'give a detailed description thereof, referring'to the accompanying Figure 1, as a vertical sectional elevation; to

Figure 2, as a plan; to r Figure 3, as an end "view; and to V Figure i, as an elevation of the axle-journal \ritlr out reinforced end. I

1 form the axle A,.of the usual material, and arange the same with the journal B between the end collars O and l). Y

Said journal will .be divided (usually irr'equal parts) by the -collars E and F, andas the end of the journal nearest to the col ars 1), acts more directly to transmit the strain from the journal-box to the wheels,

which are usually secured to the axle between the on pcsite collars D of a-axle) I reinforce said end by where the weight on the journal is equally distributed,

the journal then is arranged as indicated in fig. 4.

. 'lhe journal-box G is placed between the collars O and D, and has annular indentations H and 1,001- responding to the projecting collars E and E. The general arrangcmentof said boxes may beothem'ise, in any manner-usual or deemed advisable. It is plain that under lateral thrusts, the collars E and h, owing to increased surface obtained by theincliuation of. their sides, act clficierrtly to retain the journal-boxes, and that said inclination of the sides of said collars acts to case off or reduce the jardue to the usual side sway on movement of railroad-cars in passing curves or rails of unequal height.

The arrangement of anumber' of ccllarsintermediat-e of the ends 0 and D, atl'ords, also, additional safety in case the journal is broken at an intermediate point, since the parts of said journals between each collar E and F, and the end collar 1), are of themselv s a complete security against lateral disengagement.

The annular indentations of the boxes G, as at H and 1', act to retain oil, and thus lubricate the journal.

The arrangement of journal and journal-box, as aforesaid, may be usefully applied to all classes of axles or shafts, when there is a tendency to lateral play; "and" in all cases of applying the features of this invent-ion, the number of -collars used, and to a certain extent the angle of inclination. of the inclined sides of said collars, is determined in the discretion of the mechanic by the character and amount of the lateral strainwhich may act upon the axle or shaft.

Having thus fully described my iu'vcntiou,

I do not claim'r'einforcing the journal, .or placingtin tcrmediate collars thereon; but

What I do claim, is

The journal increased in size as the inner collar 1) is approached, by reinforcements, which are separated by- -collars E and F, r such thereof as may be deemed necessary, substantially as and for the pun poses set forth.
