retain the oil or lubricant within the 3X16.

boX, and thereby prevent waste and keep the axle lubricated, and, second, toreturn to the axle all the oilwhich maybe thrown against the lid of the box. These objects I accomplish by means of the mechanism illustrated in the accompanying drawings, in which' I Figure 1 is a side elevation ofan axle-box constructed in accordance with my invention. Fig. 2 is a longitudinal section view through the center of the same. Fig. 3 is a front view with the lid secured and with a portion of the outer flange cut away, showing the groove between the flanges and oil-drip opening from the groove to the inside of the axle-box. Fig. 4c is a detail view showing, on an' enlarged scale, the construction for preventingaccess of water to the axle-box through the joint formed by the closed lid.

Similar letters refer to similar parts throughout the several views.

A represents the outer shell or case of the axle-box, the same being constructed of any suitable material.

B represents the lid hingedto the case.

with an opening for the reception of the hingebolt E, which attaches the lid to the shell or case A. The front upper edge of the case extends upward, forminga shoulder D, which when the lid is closed comes in contact with the shoulder D of the lid, making a close-fitting joint, as shown in Figs. 1 and 4. It will be noticed that the shoulder D is onthe front upper edge of the box and'that the shoulder D is on the lid B, so that when said lid is closed the said shoulders D and D are in close contact with each other and make a tight joint. Just back of this joint there is a transas shown in Fig. 2 by dotted lines. 0 is a lug or projection on the case, provided Serial to. 680,495. (No model.)

Verse depression or channel L, which is eX-' having sufficient depth to pass to the interior I of the inner rib H, hereinafter described.

' G is an outer rib or flange made integral with the case,-and H is an inner rib' or flange. These ribs or flanges G and H are located in the box-opening to which the lid B is fitted,

and they are suitably spaced apart, as shown in Fig. 2. Between the ribs or" flanges Gand H is a groove or space which may be fitted with a packing, as shown in Fig. 2 by J. The packing, however, may be dispensed with.

K is a notch or hole throughth e rib H, designed to allow any oil which may be driven beyond the rib H into the groove to flow back into thebox. Any suitable form of spring may be used to retain the lid closed.

The axle-box is designed to contain oil or fluid lubricants, and the motion of the car will throw the oil against the lid and, as axleboxes are usually constructed, more or less is wasted. This is obviated in my invention by the use of the two ribs G and H, with the groove between such ribs, and the lid with the flange F, adapted to fit into the opening closely and extending when the lid is closed to or beyond the inner side of the inner rib, The oil thrown in contact with the lid will necessarily drive a small quantitybeyond the inner rib H, but not sufficient to pass the second or outer rib G, and consequently this oil will run down into the groove and escape by means of the vent-opening K into the body of the box. The use of the packing J will make a closer joint than can be made without it; but I have found in practice that substantially no oil will escape even when no packing is used.

Having thus described my invention, what I claim to have invented, and desireto secure by Letters Patent, is.

1. In an axle-box, the combination of a case or shell provided with a lid-opening having an outer rib G and an inner rib H therein, a. groove or space between said ribs, a dripvent K located in the inner rib and establishing communication between said groove and the interior of the case or shell, and a lid 13 hinged to the case and provided with a flange F adapted to extend inward beyond the groove between said ribs when the lid is closed, substantially as described.

2. In an axle-box, the combination of a case or shell provided with a lid-opening having an outer rib G and an inner rib H therein, a groove or space between said ribs, packing
