UNITED STATES PATENT EEIGEK GEORGE WILLIAMS, OF MYSTIO RIVER, ASSIGN OR OF ONE-HALF HIS RIGHT TO FREDERICK A. HOLMES, OF STONINGTON,CONNECTICUT.

IMPRQVEMEN'I'I IN CAR-AXLE BOXES.

Speeication forming part of Letters Patent No. 169,664, dated November-9, 1875; application tiled september 25, 1875.

To all whom it may concern Beit known that I, GEORGE WILLIAMS, of Mystic River, in the county of New London and State of Connecticut, have invented certain new and useful Improvementsin Oar Journal-Boxes; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use-the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this spec iflcatiom The nature of my invention consists `in the construction and arrangement ot' a car-axle journaLbox, as will be hereinafter more fullyset forth.

In the accompanying drawing, Figure 1 is a longitudinal vertical section of my car-axle journal-box. Fig. 2 is an end view of the same. Fig.- 3 is also an end View with the outer collar removed. Figs. 4, 5, 6, and 7 are detached views of parts thereof. i

A represents the box proper. B is the journal; C, the bearing-block for the same, and E the wedge-piece as generally used ou top of the bearing-block. The outer end of the box A is curved substantially as shown in Fig. l, and terminates in a round opening at, A', on the interior of which, at the extreme edge, are formed four or more inclinedor wedge-shaped ribs or l'langes, ct a. D is the cover to'close the opening A', said cover being provided on its inner side with four or more hook-shaped lugs, b'b, to catch on the flanges ct a, and thereby form a right or left screw for fastening the cover. On the inner end of the box A is a collar, G, provided' with a circular inside col 1 lar, G', fitting tight around the journal, the two collars overlapping each other, as shown `in Fig. l. The outer collar G is on each side provided with a vertically-slotted projection,

d, fitting on the square head of a bolt, f, which is secured to the box, and the collar is held up by means of springs e inserted in the slots` of the ears d above the bolts, as shown in Fig. 2.' Within the box A near the inner end is a slide, H, fitting tight tothe journal, forming with the-slot in the box a tight-tting oil-joint. Under the lower end of the slide H is a spring, h, to raise the slide and take the weight from the journal. Between the slide H and the col larsG G' there is left a space, t', on the journal, which is to be stuli'ed or packed with wool, asbestus, or other suitable material to keep the oil in the box in and the ldust out. This packing is set up at the bottom by means of a follower, J, and set-screw I operating thereon.

The great trouble in car-axle journal-boxes now in use is, that bythe lateral motion of the journal in the box, and the rising of the journal caused by the wearing" of the seat, the dust Works into the box and on the bearing, causing friction and heat, wearing the metal or seat and journal, and as the dust can get in, of course the oil escapes. This difculty is entirely obviated by my invention.

Having thus fully'described my invention, what I claim as new, and desire to secure by Letters Patent, is-.

The combination, with the box A and journal B, of the collar G with slotted. ears d d, interior collar G', square-headed screws f, and springs e, substantially as and for the purposes herein set forth.

In testimony-that I claim the foregoingV as my own I ax my signature in presence of two witnesses.

GEORGE WILLIAMS.
