Eeunmzme JOURNAL-Box.

T o @ZZ whom t may com/:em: Y

Be it known that I, ARTHUR BEASLEY, a citizen of the United States, and a resident of East St. Louis, Illinois, have invented certain new and useful Improvements in Equalizing Journal-Boxes, of which the following is a specication containing a full,

clear, and exact description, reference being had to the accompanying drawings,forming a part hereof.

My invention relates to an improved equalizing journal-box for car trucks, and

consists in the novel construction and combination of parts' hereinafter described and particularly pointed out in the claim found atzthe end of this specification.

Heretofoie much trouble and delay has been caused by hot boxes during the operation of trains and cars, and I have .discov` ered that in a great many cases the. trouble is caused by unequal distribution of the weight of the load upon thev car-axle journals and bearings.,l Y

The object of my invention is to provide animproved means whereby the weight of the load will be imposed equally at both ends of the journals and theirv bearings or brasses, and'thus prevent friction and its, consequential overheatmo` and undue wear and cutting of the journa sand brasses. y In the drawings, Figure l is a side-elevation, partly in section, of acer-truck side frame and its journal-boxes, having my invention applied thereto, and

Fig. 2 a transverse section, taken on the line 2 2 of Fig.'1'.

Y. The numeral 1 designates a car-truck sideframe, which mayl besof the usual construction except as to the points hereinafter particularly described 'and claimed. A The numerals 2, 3, indicate the usual' carwheels and axles, respectively. 'v

The journal-boxes t are of the yusual con-v struction, except that they each are provided with a transverse semi-circular bearing recess 5 upon their upper portions, the said bearing being located, in the present illustration ol my invention, upon the exterior of the boxes; and the bearing 5. is engaged by a cylindrical journal 6 formed. integral with and extending .longitudinally of the side-frame 1, whereby the boxes and side-frame will be hingedly or pivotally connected, and permit thesaid Aboxes to rock freely, without any correspending movement of the frame, and there- Specification of Iet''rs Patentatented June i0, QQ.

common bolt 9 extends across the bottom of said boxes 4t and connects the lower portions of said 'aws below said boxes, to prevent the boxes" om being accidentally separated from said pedestals, as well as to strengthen said jaws'. It will be observed that the said semi-circular bearing recess 5, as well as the cylindrical journal 6,v extends completely across the topV of the journal-box 4; 'thus providing a very longwearing bearing thereat, which occupies the -entire space be tween the upper ends' of 'Y the spaced-apart jaws of said pedestals 8, such a construction being made possible by the fact that the emergency means (to prevent separation of the sidevframe and journal-box) is located at thelower ends of said pedestal jaws, lin the form of thesaid bolt '9 extending across the space between said jaws, below, and entirely underneath the journal-box, as previously described.

The numeral 10 designates the brass or bearing, which rests upon said journal 7, and l1 indicatesthe usual wedge which rests upon said brass.

The operation is as follows:

When the car. carrying the side-frame and boxes, arranged as described, in accordance with my invention, runs over a rough or uneven track, the journals 7 of the axles' 3 will be alternately moved Vup and down;v but noundue 'strain will be thrown upon said sideframe, or the journals, nor upon the brass 10, because said side-trame and said boxes arein loose relation to each other, and in fact are (in the present showing) pivot ally connected; which construction will effectually prevent undue warping ortwisting of said'side-fram'e (and possible break- .age thereof at itsfweakest point, near the lwith the journal, and the wedge and lubri-v eating substance are, often displaced, the oiledr'waste being forced away from the inner end of the journal and box, leaving tile journal and brass dry, and causing heating Ysind cutting, and possible breakage of the journal.

do not limit myself to the'exact form of parts herein shown sind described, as itis clear that many changes may be mafie by skilled Workmen without departing rom the spirit and scope of my invention. A f
