JOURNAL-BOX- sPEcIFIoATIoN forming part of Lettere Patent No. 792,943, dated .rune 2o, 1905.

Application filed January 26, 1905. Serial No. 242,746.

To a/ZZ whom it may concern:

Be it known that I, JOHN W. STEPHENsoN, of Toledo, Lucas county, Ohio, have invented a new and useful Improvement in Journal- Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is an elevation, partly in section,`

of the journalbox and equalizing bar embodying my invention. Fig'. 2 is a vertical section on the line II II of Fig. 1. Fig. 3 is a View similar to Fig. I, illustrating a modified connection between the equalizingbar and the journal-box; and Fig. 4 is a vertical section on the line IV IV of Fig. 3.

In the construction of cars in which an equaliZing-loar is employed to connect the adjacent journal-boxes on the same side ot' the car difficulty has been experienced from the fact that the equalizing-bar is apt to sag and cause the boxes to tip laterally upon their pedestals, thus causing strain and wear upon the sides of the box and also upon the brass within the box, thus deteriorating these parts rapidly and constituting a source of annoyance and expense in the maintenance ofthe cars, besides increasing the friction on the journals of the axles and causing them to heat when in use. I have discovered a simple means by which these diiliculties can be overcome by interposing between the equalizingbar and the axle-box a rocking bearing, so that in case the equaliZing-bar sags it will adjust itself automatically to the box and will enable the box at all times to be in upright position parallel with the pedestals without grinding and wearing upon the latter, as above stated.

My invention, broadly considered, may be applied in many forms; but I have shown the preferable construction in the drawings,which I will now describe.

In Figs. l and 2, 2 represents the equalizing-bar; 3, the axle-box; 4, the axle; 5, the brass, and 6 the wedge. 7 7 are the pedestals between which the axle-box is set. I form on the top of the axle-box a rounded seat 8, preferably concave upwardly, on which is set a bearing-piece 9, the bottom of which is a counterpart of the bearing 8 and the top of which is provided with suitable projections 10, engaging a recess 1I on the equaliZing-bar, so as to connect thelatter to the bearing-piece 9. The use of the parts 10 and ll is not, however, essential to my invention, since these parts may be otherwise connected.

The bearings 8 and 9, as shown in Figs. 1 and 2, may be spherical in their surface contour, so that the bearings will adjust themselves in any direction, and in case the equaliZing-bar should sag or become displaced laterally Jfor any cause this self-adjustment of the bearings will prevent such shifting of the bar from canting the axle-box.

In the modification shown in Figs. 3 and 4 the curved bearing between the parts 8 and 9 is cylindrical in contour, so as to a'ord an adjustment only in the planes parallel to the equaliZing-bar, and thisconstruction for most purposes is preferable. In both cases it will be noticed there. is a clearance between the parts 10 and 1l, so as to allow a slight lateral sliding of the bearing-piece 9 on the equaliZing-bar, since this is necessary in order to obtain complete adjustment; but this sliding bearing may be provided for in other ways than as shown.

The parts may be modified. Thus the bearing-surface 8 may be convex and the adjacent surface of the part 9 may be concave.

I claim- 1. In combination with a journal-box and equalizing-bar, a rigid bearing-piece affording a rocking bearing between said journalbox and bar; substantially as described.

2. In combination with a journal-box and equalizing-bar, a rigid bearing-piece between these parts affording a rocking bearing and ai'ording also asliding bearing withthe equalizing-bar; .substantially as described.

3. In combination -with a journal-box and equalizing-bar, a bearing-piece having a rocking bearing of cylindrical outline on the top of the journal-box, and havinga sliding bearing on the equalizing-bar; substantially as de- In testimony whereof I have hereunto set scribed. my hand.
