SPECIFICATION forming part of Letters Pa tent No. 389,343, dated September 11, 1888.

Application filed December Q2, 1886. Renewed April 11, 1898. Serial No. 270,278. (No model.)

To aZZ whom it may concern:

Be itknown that I, FRANCIS SHALISTULL, of Galveston, in the county ofGalveston and State of Texas, have invented certain new and useful Improvements in Railway-Oarlrucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to railway'car trucks; and it consists in providing the axle inside the wheel with asupplementaryjournal and shoulder and a supplementary journal-box supported above the inside journal by the truckframe, said supplementary journal-box being immediately over the inside journal and arranged so as to support the truck on the inside broken or inoperative by reason of a hot box or otherwise, all of which will be more fully hereinafter specified, and pointed out in the claim.

In the accompanying drawings, Figure 1 represents a front sectional view of a railwaycar wheel and a portion of an axle provided with the usual outside journal, and also provided with my supplementary inside journal and journal-box. Fig. 2 represents a side ele vation of the supplementary journal-box, and also a sectional view of the axle therein. In this view the parts are shown in their normal position, the brass being elevated above the inside journal. Fig. 3 represents aside elevation of the supplementary journal-box and journal, the several parts being shown in the position they occupy when the truck-frame and car are supported by the inside supplemental box.

Like letters of reference indicate like parts in the several views.

The letter A indicates the car-wheel, and B the usual outside journal.

C represents the hub of the wheel, and D the axle inside the wheel. Said axle is provided with a shoulder, E.

F is a supplementary box encircling the inside journal, G. The inner side of the hub G acts as a shoulder for the box F, and theinner side of the hub and the shoulder E limit the lateral movement of the box F. The upper part of the box F (indicated by the letter F) is secured to the underside of the truck-frame by bolts or other suitable means. This supplementary box is normally carried above the inside journal; but it is lowered to engage and rest upon the axle or supplementary journal G should the outside journal be broken.

Hindicates a brass block seeu red in the box F and supported above the inside journal or hearing, G. This block is shown in Fig.2 in its normal position when the outside journal is unbroken.

The letter I indicates an oil-reservoir in the supplementary box F. This reservoir is located immediately above the inside journal, G. The reservoir I is provided with a central bottom opening, J. Said opening communicates with a corresponding opening in the brass H, whereby com munieation may be had with the oil-reservoir I and supplementary journal G, so as to admit oil to said journal when the box is called into requisition.

K is a valve fitting into a circular bevel-seat in the bottom of the reservoir I. This valve is provided with a stem, K, which projects downwardly through the openings in the reservoir and brass. It will be observed, Fig. 2, that this stem is normally carried immediately above, but in close proximity to, the upper side of the insidejournal, so that should the outside journal become broken and inadequate to support the truck, the truck-frame thereby being lowered and supported by the inside box, the said stem and valve are thereby elevated, thus permitting the oil in the reservoir to flow and lubricate the supplementaljournal G. The valvestem is of less diameter than the openings through which it passes, so that when the stem and valve are elevated the oil will llow freely onto the supplemental journal.

Owing to the fact that the whole weight of a car rests on the journals, said journals frequently break from the excessive weight. The greatestdangcr, however, to the journal arises from hot boxes. The excessive friction incident thereto is a frequent cause of breakage of thejournal, and such an accident is usually attended with disastrous results.

The object of my invention, as hereinbefore specified, is to temporarily provide a means for supporting the truck and car when these breaks of the journal occur, and it will be ap ICO parent that the means above described effecttruck in case of breakage of the outer or end to ively serve that purpose. journal of the axle, substantially as set forth. Having thus described myinvention,I claim In testimony whereof I have signed this as new and desire to secure by Letters Patent specification in the presence of two subscrib- The combination, with a car truck, wheel, ing witnesses.
