JOURNAL-1B OX.

To all whom it may concern:

Be it known that I, WVILLIAM citizen of the United States, residing in the city of Baltimore and State of Maryland, have invented a new and useful Improve ment in Journal-Boxes, of which the following is a specification.

This invention relates to improvements in journal boxes and more particularly to those used on railway locomotive tenders, assenger, freight and other car boxes Whic have the journal boxes located on the axles outside of the wheels. It will be understood, however, that the invention may be applied toother forms of journal boxes without departing from the spirit of the invention.

The improvements consist essentially 1n providing means for ventilating the interior of the journal boxes so that the stale air within the journal box, external to the journal and bearing and alongside of same, is

E, Cxisr, a

change being caused by nozzles either of the direct or the induced draft type and so 10* inside the journal box directly alongside o the journal and its bearing.

My invention consists more specifically in providing an air inlet and an air outlet communicating with the space inside of the joun nal box directly around and about and alongside the outside of the journal bearing. These inlet and outlet orifices may be combined in a single hole or orifice, or there may be two such orifices, one ip the Forward and one in the rear side of the main portion of the journal box or ,two sets of such inlet and outlet holes arranged as desired on the journal box.

urthermorflny improvements may consist in a structure wherein the cool or outside air passes directly into the journal box from the .front or advance sideof the our- .nal box as thetrain is moving, and which will thus force the heated air within the journal box out at the rear side, and the cool thus replace the heated air. The ingress and egress of the air may be made through orifices directly in line with each other or the air may be made to follow a more tortuous course. On the other hand, the inlet and outlet orifices maybe so constructed that the cool air is drawn into the journal box from the rear side of the mov- Speeification of Letters Patent.

ing journal box, and the heated air drawn out at the front side, and in this latter case, the use of a partial vacuum is employed, as will be better understood from the following description.

By the structure which I employ, a convthat is practically non-heating, and thus prevents the delays in operating trains caused by heated car journals, and thereby materially reduces the cost of maintenance of the same. It will also be obvious that my be applied not only to My invention furthermore consists in the novel lmprovements m the parts and devices and in the novel combinations of parts and i devices herein shown, described and claimed. cated that they will act upon the air space In the drawing, wherein is illustrated one form of my invention, and the one which I now considerpreferable, Figure 1 is a side view of a journal box showing my improvements. Fig. 2 is a vertical section of the improved journal box, taken on the line 2-2 of Fig. 1, and looking in the direction of the arrows, Fig. 3 is an enlarged detail, sectional view taken on the line 33 of Fig. :2, looking in the direction of the arrows.

In the drawings, 10 represents the main portion of the journal box, which is provided with the usual lugs 11 and 12 on the sides thereof, by means of which the journal box is adapted to-be bolted to the car truck. On each side of t hmmain portion 10 of the journal box is a shel or outside member 13, forming with the inner portion 14:, a. vertically extending recess 14., as more clearly shown in Fig. 2, and having an open ing 15 at the bottom thereof and also an opening 16 at the top. The innemportion 14 of the main member of the journal box is provided also on each side with a hole or orifice 17, which is located substantially opposite the hole or orifice 16 in the outer shell member 13, as shown in the drawings which are merely illustrative. Located between each of the outer portions 13 and the inner member 1a and preferably cast integrally therewith, is a Web or plane 18, each of said plates 18 extending beyond the lower portions of the holes or recesses 16 and 17.

Preferably located in each of the orifices 17 is a screen 19, removably secured therein as by means of t resilient coil member 20 adapted to be seated in a groove 21 in the inner portion 14' of the journal box, said screen 19 abutting a ledge 22 in the mem' her 14.

It Will be apparent that it the journal box is mounted on a train going in the direction indicated by the arrow (0 in Fig. 2, that the atmosphe'ie pressure will be increased on the for vard or advance side of the journal box, and that a current of air will flow in the direction, as indicated by the small arrows 6. Such a flow of air will produce a partial vacuum between the Web 18 and the inner portion 14;, thereby drawingthe heated air from the interior of the journa box through the orifice 1?, which will then mix With the flow of air being forced through the hole 16 and which. will then pass out at the hole 15. in this way, a partial vacuum is created in the interior oi the journal box, which in turn induces un inflow of air through the orifice 17 on the rear side of the journal box. it will be oh- YlOHS "when the train goes in the opposite direction, that the low oii air through the journal box will be in the reverse direction, or in other Words, that up n the train going in one direction, one hole or orifice errc as the inlet hole and the other for the m hole, and that upon going in :iuotl direction,jthe function of hen Any suitable form of cover or n be used 'With the journal box.
