Description

Oct 1956 w. J. WALSTAD ADJUSTABLE RAILROAD JOURNAL LINER Filed Nov. 3 1954 IN VENTOR ATTORNEY United States Patent 2,766,077 ADJUSTABLE RAILROAD JOURNAL LINER Walter J. Walstad, Flint, Mich. Application November 3, 1954, Serial No. 466,599 1 Claim. (Cl. 308554 This invention relates to railway car journal box liners and brasses wherein the contacting elements are positioned in the upper end of a journal box and wherein, due to the diameter of the journal or axle is invention is to provide means for continuously adjusting the inner surface of the brass of a railway car journal box so that the same bearing elements may be used throughout the life of the journal.

With ordinary use, a conventional journal or axle of a railway car decreases from the original size, such as /2" in diameter to a minimum size, such as 5", and is then discarded. As an example, in being reduced from a 5 /2 journal to a 5" journal, open spaces are found on the sides and the only actual bearing surface is at the top. With this thought in mind, this invention contemplates the use of hinged bearing segments in the liners with set The object of this invention is, therefore, to provide means in a railway car journal box liner whereby wearing surfaces of the liner are adapted to be adjusted to journals or axles of different diameters.

Another object of the invention is to provide adjusting means in a journal box liner without increasing the size of the liner and wherein the parts are adapted to be installed in journal boxes now in use.

A further object of the invention is to provide an improved railway car journal box liner in whichrthe bearing surface thereof is adjustable and in which the device is of a simple and economical construction.

With these and other objects and advantages in view, the invention embodies an improved railway car journal box liner patterned to be installed in the upper end of the journal box and having wearing elements hinged at the center and adapted to be adjusted with set screws threaded in the sides of the liner.

The invention also includes a reinforcing center strip corresponding to the end plates of a railway car journal box whereby the cover or wall of the journal box is supported at the ends and center.

Other features and advantages of the invention will appear from the following description, taken in connection with the drawing, wherein:

Figure 1 is a cross section through a railway car journal box with the box and axle shown in broken lines and showing in particular a liner with hinged wearing elements therein, said section being taken on line 11 of Figure 2.

Figure 2 is a view looking upwardly toward the under Patented Oct. 9, 1956 Figure 3 is a cross section through the bearing taken on line 33 of Figure 2, the wearing elements being adjusted to positions for contacting a journal of a reduced diameter.

Figure 4 is a view showing the hinged wearing elements with the liner and other parts omitted.

Referring now to the drawing, wherein like reference characters denote corresponding parts, the improved bearing of this invention includes wearing segments 10 and 11, screws 12 and 13 pivotally connecting the segments, a continuous liner 14 having

end plates

15 and 16 and a center rib 17 and set screws 18 threaded liner or brass and positioned to engage outer surfaces of the segments 10 and 11 whereby the segments are adjustable to compensate for wear of journals or axles, as indicated by the numeral 20.

The liner or brass 14 is lines, and with the liner positioned as shown in Figure 1', the segments 10 and 11 are adapted to engage the surface of a journal or axle. As the journal or axle wears, such as from the large diameter indicated by the broken lines 20 to the smaller diameter as indicated by the broken lines 23, the positions of the segments are adjusted accordingly by the set screws 18.

In the design shown, the brass or liner 1 4 is formed with a fiat upper surface 24 and inclined surfaces 25 and 26 at the corners, however, it will be understood that the brass or liner may be designed to correspond with upper inner surfaces of journal boxes or other types and de- The edges of the liner are pnovided with vertically disposed walls 27 and 28 and

projections

29 and 30 are provided at the lower edges of the walls. The

flanges

15 and 16 are provided at the ends and a similar flange, as indicated by the numeral 17 is provided at the center, and as shown in Figure 3, the flange 17 forms a rib on the The segment 10 is provided with tongues 32. and 33 that extend into recesses in the

are provided with stepped The pin 13 extends through an opening 48 in the tongue 37 and also through an opening 49 in the flange or end wall 16.

Should it be desired to carry the rib or center flange 17 downwardly to the surface of the axle or journal to correspond with the

end walls

15 and 16, segment assemblies, as shown in Figure 4, may be provided at both sides of the rib.

With the pants assembled as the improved adjustable journal and 11 contact the surface of the journal. These wearing plates or segments are adapted to be adjusted as the journal wears so that continuous contact is provided between the inner surfaces of the bearing elements and the journal.

The wearing elements or segments 10 and 11 are adapted to 'be removed and replaced as desired.

It will be understood that modifications, Within the scope of the appended claim, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

In a bearing for use with a car journal bearing in a railway car journal box, the combination which comprises a brass having a cavity in the under surface with flanges at the ends of the cavity and with a rib corresponding with the flanges in the center of the cavity, hingedly connected wearing segments pivotally mounted in the brass and positioned with the pivotal mounting in a vertical plane extended through the axis of a journal of the journal box, and positioned to engage and set screws threaded in the brass the upper surfaces of extended ends of the segments.
