SPECIFICATION forming part of Letters Patent No. 511,656, dated December 26, 1898.

Application filed January 18, 1893. Serial No. 458.816. (No model.)

To @ZZ whom, t may concern.'

Beit known that I, WILLIAM SMALL, `Ir.,of Kansas City, in the county of Jackson and Stateof Missouri,have invented certain new and useful Improvements in Journal-Bearings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements in journal bearings, for railway cars, shaftings, the.; and my invention consists in certain features of novelty hereinafter described and pointed outin the claims.

Figure I, represents an elevation of a railway truck, with my improved journal box and bearings in connection therewith. Fig. II, is an enlarged front elevation of the bearing and box, with the front plate removed. Fig. III, is a vertical sectional view taken on line, III, III, of Fig. II. Fig. IV, is a front elevation, with plate removed, showing a slight modification. Fig. V, is an enlarged detail perspective view of the hinged supporting bar. Fig. VI, is a perspective view of the serrated wedge for holding` bearings Fig. VII, is a transverse section taken on line, VII, VII, of Fig. II, looking upward. Fig. VIII, is a transverse sectional view taken on line, VIII, VIII, of Fig. II, looking downward. Fig. IX, is a transverse sectional View taken on line, IX, IX, of Fig. II. Fig. X, is an enlarged detail perspective of one of thebearing blocks or brasses. Fig. XI, is an enlarged detail side elevation of the hinged supporting bar.

Referring to the drawings: l, represents the wheels of a railway truck, resting on rail, 2.

3, represents the supporting frame, supported by an upper bar, 4, and a lower bar, 5; the lowerbar, 5, forming an arch, and secured to a horizontal bar, 6, which in turn 4is secured to the boxes, 7, in which the axles have their bearing, said bar, 5, thus forming a brace in connection with the bar, 6, thus bringing a portion of the strain on the lower portion of the box. The bar, 4, passes beneath the frame, 8, and extends up to and is secured to the top of the boxes, 7.

8, represents a top horizontal bar, which is also connected with the boxes, 7, at their up per ends. The box, `7, is constructed of two sections, 9 and 10, divided vertically, so that one section may be removed in order to place the bearings within the box, the section, 10, having a lip, 11, beveled as shown at 12, and the section, 9, having an under lip, 13, beveled, as shown at 14 thus providing a scarf joint between the two sections 9 and 10 at the top; said sections being also provided with a beveled scarf joint at their bottoms, as shown at 15, thus forming a close union, and bracing each other when the two sections of the box have been placed in position. Each of the sections, 9, 10, of the box is provided with lugs, 16, having central apertures, through which bolts, 17, are inserted, for holding said sections together.

18, represents bolts extending up from the bottom of the box through the lower bar, 6, through lugs, 19, 20, cast on the box, and having nuts, 21, secured thereto for holding the lower bar, 6, in contact with said box.

22, represents bolts extending downwardly through the upper bars, 4, 8, passing through lugs, 19, 20, in the same manneras atthe lower end of the box, and held in position by nuts, 23. The bars, 4, 8, are provided with hinged sections, 24, 25, hinged to the main portion of the bar, as shown at 26; whereby, when it is desired to remove t-he section, 9, of the box, said hinged sections maybe raised, as shown in Figs. V and IX. After the outer bolt, 22, has been' removed, then by removing the outer bolt, 18, and the cross bolts, 17 the outer section, 9, of the box may be removed, in order to place or re-adjust the bearings to the axle or shaft, which greatly facilitates the repairing and the insertion of said bearings in the box.

27, represents an axle having bearing blocks or brasses, 28, with lugs, 29,0n the rear of the same, whereby said brasses may be secured at the lower end of the box to form a bearing for said axle. After the blocks, 28, have been placed in position, keys, 30, are dropped down through the openings, 81, at the rear of said blocks, to hold them in close connection with said axle.

32, represents a rubber dust cap around the axle, 27, for the prevention of dust entering the box.

33, represents roller bearings, or wheels,

IOO

having a shaft 34, said wheels, 33, resting on the axle, 27, and having bearing blocks, 35, at each end of the shaft, 34, said bearing blocks being held in contact with said shaft by means of set screws, 36, working in brackets, 37. By this means the bearings, 35, can be changed to compensate for wear of the shaft, either in a horizontal or in a vertical direction; the brackets, 37, having openings,38, in order to give access to the set-screws, said set-screws having threaded bearings on either side of said opening. I

39, represents a larger wheel resting on the shaft, 34, between the roller bearings, or wheels, 33, said wheels, 33, being provided with bosses, 40, which guide the wheel, 39, and keep the same in alignment; said wheels, 33, also having bosses 4l, on their 4outer sides, which form bearings against the sides of the blocks, 35, in order to assist in keeping said wheels in alignment.

42, represents blocks set within the box, and resting on the axle, 43, of the wheel, 39; the upper portion of the box resting on said blocks,

2, and having oil chambers, 44, therein, said oil 4chambers connecting with the interior of the box and bearings, by means of apertures, 45, in the blocks, 42; said box where it rests upon the blocks, 42, being'provid ed with packing, 46, which prevents the escape of oil around said block.

47, represents a recess in the top of the box between the lugs, 16,in which the supporting strap or braces, 4, 8, rest.

48, represents a door having a lug, 49, at its upper end, which fits over a liange, 50, on the box, having an end piece, 51, for raising said door, said door being held in close proximity to the box at its lower end by means of a flange, 52, extending outwardly from the box a sufficient distance to permit of a recess, 53, into which said door slides:

In lieu'of the'smooth key, 30, I have provided as a modification a serrated wedge, 54, to be inserted behind the wearing blocks, 28; the box also having a serrated face, 55, with which said serrated wedge engages. Thus, as said blocks Wear, the wedges,'54,wil1 descend, keeping the bearing close to the axle,and the serrated edgesof the same,preventing the wedges from becoming loosened, or jumping out of the recesses into which they are placed. The wheel, 39, is also provided with bosses, 56, which come in contact with the sides of the blocks, 42, and serve to assist in keeping the Wheel, 39, in alignment.

By means of my vertically divided box, and

the construction shown, I am enabled to remove one side 'of the same, and readily place the bearings in position, or repair the same; it having been found to be agreat disadvantage to be under the necessity of placing the bearings in endwise from the front of the box.

I claim as my invention- 1. In a journal-bearing, thecombination, with upper and lower supporting bars; of the box constructed of two sections having beveled scarf joints located at the top and bottom of the box, the perforated lugs at the top and `bottom of the box, and the perforated upper and lower .lugs located at the sides of the box, and the top, bottom, and side bolts by which the parts are secured together; substantially'as and for the purpose set forth.

2. In a journal bearing, the combination of a vertically divided box, lower supporting bars, hinged upper supporting bars, and upper and lower bolts engaging Vsaid bars and said box, for connecting said Abars with the box; substantially as and 'for the purpose set forth.

3. In ajournalbearii-ig,"the combination of a box for containing the bearings, upperand lower supporting bars, bolts for holding said bars in connection with said box, said upper bars being provided with a hinged section; substantially asand for the purpose set forth.

4. In ajournal bearing,the combination of a vertically divided box having lugs, 19, 20, bolts, 18, 22, supporting bars, certain of'said bars being provided with hinged portions, in order that one section of said 'box may be readily removed from the remaining portion of the box; substantially as and for the purpose set forth.

5. In ajournal bearing, the combinationot' a shaft or axle va box, bearings, 28, and serrated wedges for holding said bearings in (contact with the shaft or axle; substantially as and for the purpose set forth. K

G. In a journal bearing, the combination of a journal box formed of sections having bearing blocks, 35, brackets, 37 having openings. and set screws engaging in said brackets and operated through the opening for holding said bearing blocks in position; and a rollerbearing havinga shaft mounted in the blocks substantially as and for the purpose set forth.
