JOURNAL-BEARING FOR MINE-CARS'.

SPECIFICATION forming part of Letters Patent No. 681,997, dated September 3, 1901.

Application filed December 6. 1900. Serial No. 38,934. (No model.)

To all whom t may concern:

Beit known that I, DAVID J. SULLIvAN,a citizen of the United States, residing at Jermyn, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Journal-Bearings for Mine-Cars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to an improved automatic lubricating journal-bearing for minecars.

The object of the invention is to provide a journal-bearing of this character from which the journal when bent, broken, or otherwise injured may be readily removed to detach the axle without the necessity of unloading the car or tipping it over on its side.

With this and other minor objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is an outer or front side elevational View of a journal-bearing embodying my invention. Fig. 2 is a top plan View thereof. Fig. 3 is a vertical longitudinal section on line 3 3 of Fig. 2. Fig. 4 is a similar view on line 4 et of Fig. 2. Fig. 5 is a vertical transverse section on line 5 5 of Fig. 1. Fig. 6 is a similar view on line 6 6 of Fig. 1. Fig. 7 is a detail bottom perspective view of the upper or fixed section of the bearing. Fig. 8 is a detail top perspective View of the lower or sliding section of the bearing; vand. Fig. 9 is a view similar to Fig. 2, showing the sliding section opened to release the axle-journal.

Like reference characters designate corresponding parts throughout the several Views.

Referring now more particularly to the drawings, the numeral 1 represents the iixed or stationary section, and 2 the movable section, of my improved journal-bearing. The stationary section comprises in its construction a horizontal plate or bracket 3, provided with openings 4. for the passage of' bolts or other fastenings for attaching it to the car.

Between these openings the plate or bracket is provided on its under side Withan exten- .sion 5, which is concaved on its under side, as shown at 5, to form the upper portion of the box or bearing for the axle-journal 6, and in the plate 3 above said concavity is formed an oil chamber or reservoir 7. The top of this chamber is formed by the plate 3 or an extension from the upper surface thereof, and access thereto is obtained through a hinged or pivoted door 8, located upon the outer side of the plate or bracket. From one side of the said extension 5 a box-section 9 projects downwardly and is provided upon its inner face with an inclined shelf 10, a recess 11 at the base and outer side of said shelf, and an inclined conducting-wall 12, leading from the adjacent side of the base ot' the extension 5 to said shelf. The box or bearing portion formed by said extension is open at one side for the passage of the axle-journal and partly closed at the outer side by the outer or front wall 13 ofthe extension 5 and box-section 9. Feed- passages 15 and 16 extend from the oilchamber 7 through the bottom of the extension 5 and open at their lower ends upon opposite sides of the concavity 5a. These passages are adapted to feed the oil or lubricant to opposite sides of the journal-box in the manner hereinafter described.

At the side of the extension 5 opposite the box-section 9 the bracket or plate lis grooved at 17 to receive tongues 18, formed upon the upper surface of the body orr bracket portion 19 of the movable bearing-section 2. This body or bracket portion carries at its inner end a box-section 20, which cooperates with the section 9 to form a complete journal-box and oil-reservoir. This section 2O is composed of an outer side wall 21, a bottom wall 22, afront wall 23, and a rear wall 24E, the latter having its upper edge concaved in conformity with the part 5@ to serve as a bearing for the axle-journal. The outer side wall 21 is formed at its upper end with a shoulder 25, upon which the lower and outer edge of the extension 5 at one side of the concavity 5L rests, while the upper and inner vertical edges of the front wall 23 and the inner edge of the bottom wall`22 are formed with a continuous tongue or ilange 26, which enters the recess 1l and a groove or recess 11, formed in the box-section 9 and upon the inner side IOO of the front wall 13 of the extension 5, whereby when the section 2 is closed a liquidtight connection between the two box-seetions is insured. The inclined shelf 10 of the part 9 laps over the portion of the flange 26 along the inner edge of the bottom wall 22 of the box-section 2O and lies flush with the said inner edge of said bottom wall, which is beveled or inclined, as shown at 27. By this construction a continuous inclined conductor is formed by the parts 12, 10, and 27 for the free flow of the lubricant from the passage 16 past one side of the journal and into the base of Vthe box-section 20', which forms a chamber or reservoir 28 to receive the Waste which is kept saturated with oil to lubricate the journal. The passage 15 in like manner feeds oil to the opposite side of the chamber 28, the oil iiowing down the outer side wall 21 of said chamber. When the section 2 is closed, it will be noted that the rear of the journal-box is left open to receive the bearing, While the frontV thereof is closed by the walls 13, 14, and 23 to exclude dust and dirt as much as possible.

The two sections 1 and 2 are adapted to be secured in closed position by a key 29, mounted to slide in a keeper 30 on the section l and to engage a corresponding keeper 30 on section 2. This key is provided at its lower end with a bit or lug 3l, adapted when the key is moved to pass through the clearance slots or notches 32, formed in said parts, and to abut against a shoulder 33 to limit its retracting movement when drawn up to release the section 2. A longitudinal groove 34 is formed in the under side of the plate or bracket 3 of the section 1 and has at one end a shoulder 35. A set-screw 36 on the section 2 is adapted to traverse this groove and to bind against the bracket 3 to hold the parts securely connected, also to abut against said shoulder 35 to limit the outward movement of said section 2 and prevent entire disconnection thereof from the section 1.

In practice the plate or bracket 3 of the section lis bolted or otherwise secured to the mine-car, the journal 6 of the axle placed in position in the part 5, and the section 2 then closed up to confine the journal. The oil or lubricant is then placed in the chamber 7 and feeds automatically by gravity through the passages 15 and 16 to the chamber 28, by which the journal is at all times effectually lubricated.

When a wheel or axle becomes bent or broken, the car may be jacked up without unloading, and by simply sliding back the section 2 of each journal-box, as shown in Fig. 9, the journals will be released, leaving the axles free to drop out of the bearings. A new axle may then be quickly and conveniently placed in position and the boxes closed up to confine the journals thereof.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood, and it will be seen that an extremely useful and desirable journal-bearing is provided.

While the preferred embodiment of the in ven tion is as herein disclosed, it will of course be understood that changes in the form, proportion, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacriticing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In combination with a car-axle journal, a journal-box comprising a stationary member adapted for attachment to the car, and a movable member slidable transversely of and toward and from the journal, said members havinginterfittin g portions forming a divided box to inclose the journal, substantially as set forth.

2. A journal box or bearing for car-axles, comprising a stationary section composed of a bracket adapted to be attached to a car and having a transversely-extending box-section and longitudinaledge and intermediate guidegrooves, a movable section provided with a complementary transverse box-section and tongues slidably engaging the edge guidegrooves on said stationary section, a set-screw on the movable section and entering the intermediate guide-groove on the stationary section, and a key for holding the movable section fixed and the box-sections in engagement with each other, substantially as set forth. p

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
