SPECIFICATION forming part of Letters Patent No. 289,053, dated November 27, 1883.

Application filed August 10, 1853. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM W. WonswIeK and NORMAN W. CUTTER, of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Axle-Journal Boxes; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use the same.

Our invention relates to improvements in axle-journal boxes for railwaycars; and it consists in certain features of construction and in combination of parts, hereinafter described, and pointed out in the claims. The object of our invention is to improve a journal box on which Letters Patent were granted to the said lVilliam W. W'orswick, March 11, 1879, No. 213,082, and to which reference is made in this specification.

In the drawings, Figure 1 is a plan view of the bottom of our improved journal-box. Fig. 2 is a view in elevation of the filling-piece D.

Fig. 3 is a transverse vertical sectional view of our bearing. Fig. 4 is a horizontal sectional View of the box with the axle and rollers removed, and Fig. 5 is a view in elevation of the end piece.

A represents the shell of the box, and, as shown in Fig. 1, has wings or fiangesA, suitable for attachment to horse-cars. The outer form of the box is changed more or less, ac cording to the different uses to which it is applied. Inside of the box are the anti-friction rollers B, surrounding the axle C. These rollers have each an annular groove in the center, that embraces the rib a on the inside of the box. This rib, at the bottom of the box,

1 about fills the grooves onthe rollers, but

gradually decreases in width in either direction, until at the top of the box the rib is quite narrow. As the rollers approach the Bottom of the box and are free from any pressone from the axle, they come in contact with the broad part of the rib a, and are there by brought into proper position lengthwise. As they again approach the upper portion of the box: and come in contact with the axle and receive the pressure thereof, the rollers are free from any contact with the guiding rib,and are only held endwise by friction on the box.

As shown in said former Letters Patent, there was an aperture through the box that severed the said rib, and through the gap in the rib the rollers were inserted endwiseinto the box and around the axle. These axles are frequently made smaller at the journal, leaving shoulders on either side, andin such cases the rollers could not be placed in the box in the manner just described. Instead of the short aperture that merely severed the rib a,we now make a chamber, as shown in Fig. 1, that is longer and broader than the rollers, and by means of which a roller may be placed sidewise into the box and between any shoulders, flanges, or collars that may be on the ends of the journal.

D is a cap with the raised portion d, that fits into the said chamber and comes flush with the inside of the box. There is also a part, d, that fills the gap in the rib, so that when the cap is secnredinits place in the box there will be a smooth surface for the passage of the rollers, both on the bottom of the box and on the sides of the rib. It was found that with 7 5 wholly of cast-iron the top part of the inner surfacethat is, the portion that sustains the weight-would soon wear and become out of round. As an improvement,we now chamber this part of the box on either side of the rib, and insert therein lining-plates, preferably of steel, although any other metal orsubstance may be used, if desired. There is little wear on other parts of the box,andthese steel plates, by means of their superior quality of metal over cast-iron, and by means, also, of an occasional renewal of the plates, render this part of the box equally durable with the other parts thereof. These plates areinserted from either end of the box and come in firm contact with the shoulders a, and are thus held without other fastening. These shoulders. and the edges of the lining plates are beveled, as shown, thus forming dovetails, that in any event will hold the edges of the plates back in their position against the box.

E is an end plate for the front or-outer end of the box, and is provided with a projection or raised part, c, that may project more or less into the box, as may be required. This projection is integral with the end plate, and is chilled in casting. The relation of the parts is such that the said chilled surface receives the end-thrust of the axle, and by this construction a cheap and convenient manner is had of supplying a hardened surface to receive the wear at this point. Attached to the outer side of this plate is a suitable oiling device, by means of which the box is supplied with oil. WVe do not limit ourselves to the use of these boxes on street or horse cars, as they are equally adapted to steam cars and various other purposes.

What we claim is 1. The combination, with a box or casing having a suitable opening formed therein on its lower side below the axle, the said opening being slightly longer than the anti-friction rollers, and the anti-friction rollers, of a filling-pieceseoured to-thebox orcasing'by-screws, andadapted toclose the opening in the box,

substantially as set forth.

2. The combination, with abo'x creasing ipro'v'id'ed withan internal rib, and liavi-ng'an I oblong opening through the bottom thereof for the introduction of anti-friction rollers, of the filling-piece D, adapted to close the opening, and provided with a projection adapted to register with the rib of the casing, and grooved anti-friction rollers, all of the above parts combined as described.

3. The combination, with a boX or casing provided with the ridge a, groovedanti-friction rollers situated within said casing, and an axle, of the end pieces, E, provided with ahardened projection, 6, adapted to receive the'endthrust of the axle, substantially as set forth.

In testimony whereof we sign this specifica tion, in the presence of two witnesses, this 6th day of August, 1883. I
