'VVILLIAM S. G. BAKER, OF BALTIMORE, MARYLAND.

CAR-AXLE Box;

SPECIFICATION forming part of Letters Patent No. 292,399, dated January'22, 1884.

Application filed September 21, 1883. (No model.) I

To 0. whom it may concern Be it known that I, WILLIAM S. G. BAKER, of the city of Baltimore and State of -Maryland, have invented certain new and useful Improvements in Gar-Axle Boxes, of which the following is a specification.

My improvements relate to car-axle boxes of the class shown and described in United States Letters Patent heretofore granted to me; and my present invention is designed to afford means for completely closing the box, so as to exclude dust and other foreign matter. My improvements, therefore, have reference to the box-lid and to the washer or washers interposed between the wheel and the box.

In the accompanying drawings, Figure lis an elevation, partly in section,- of my improved axle-box; Fig. 2, an end view thereof; Fig. 3, a sectionshowing the arrangement of washers, and Figs. 4, 5 illustrate a modification of my improved lid.

The outer end of the boxA is formed with an opening, B, the sides of which are preferably inclined from top to bottom, as shown. At the upper end of the opening is a shoulder,

a, which extends transversely across the box.

The top of the shoulder is preferably on a somewhat lower planethan thetop ofthe box, and a transverse channel, 0, is preferably formed between the shoulder or rib and the portion 6 of the box. The .lid 0 is formed with a hooked end, D,'the socket d and shoulder d corresponding, respectively, with the shoulder a and channel 0 on the box, so that when the lid is in position there will be a neat fit, the top of the lid being parallel with the top of the box. The lower end of the lid is hinged on a pin, E, which is supported in brackets e on the box. On the outside of the lid are formed lugs F, preferably elongated, as shown, which are provided with slots f, through which the hinge-pin extends. The slots are of sufficient length to allow the lid to be lowered to its locked position, or raised sufficiently to clear the shoulder a. WVhen thus raised, the lid may be swung back on its axle, as illustratedby dotted lines in Fig. 1. When the lid-is closed, it is held firmly in position by the set-screw G, which is carried by a frame,

g, hinged to the pin E. The screw works against a lug or bracket, g, formed on the lid.

cam, I, carried by a hinged frame, 2'.

When it is desired to open the box, the screw may be loosened and the lid raised and turned on its hinges, as illustrated .in Fig. 1.' The frame 9 of course moves with the lid, and finally abuts against the stop H.

The details of construction in my improved lid may be somewhat varied.

In Figs. 4 and 5 I have shown a substitute for the set-screw. It consists of an eccentric The cam works against a bracket, formed on the lid'.

The operation of the cam need not be described, as it is merely amechanical equivalent or substitute for the set-screw.

The general formation of the inner end of the box is similar to that shown in my United States Patent No. 276,210, of April 24, 1883.

My improvements now relate to the formation and arrangement of the washers which areinterposed between the wheel and the box. In the patent above mentioned Ihave shown a car-wheel provided with pins or lugs which fit into sockets in an annular metallic washer, whereby the washer is held so as to revolve with the wheel. Between the pins are arranged coiled springs, which are secured to the washer, and which bear against the face of the wheel, and tend to hold the washer against the face of the axle-box.

My present improvements consist in an annular metallic washer, J, formed with pins or dowels j, which fit into sockets k in the wheel K. Alternating with the dowels are coiled springs L, which are secured to the washer in sockets Z, and bear against the face of the wheel, and tend to hold the washer against the face of the axle-box. The washer J is preferably formed with segmental flanges j, into which fits-a fibrous washer that bears against the face of the box.- The washers fit neatly over the axle N, and effectually exclude from the interior of the box dust and other foreign matter.

It is advantageous to form the dowels on the washer instead of on the wheels, because the dowels are, then not so likely to be bent or broken, and it is more convenient to thus manufacture them, and, in case of breakage, a new washer may readily be'substituted, if necessary.

I claim as my invention- 1. The combination, substantially as set forth, of the box, the hinged lid, theloeking-shoulder thereon, the hinge-pin carried by the box, the slotted bearings in the lid through which the pin extends, and means carried by the box for holding the lid in its locked position.

2. The combination of the box,the lid hinged thereto, the locking-shoulder on the lid, the hinge-pin carried by the box, and the slotted bearings in the lid through which the pin extends, and which permit the lid to have a slight vertical movement to disengage thelocking-shoulder, and then an outwardly-swinging movement to open the box, substantialy as set forth.

3. The combination of thebox,thelid hinged thereto, the slotted bearings in the lid, the swinging framemountecl on the box,and means carried by the frame for holding the lid in position, substantially as specified.

4. The combination of the box, the vertically-sliding lid, theloekingshoulder thereon, the frame mounted on the box, and means carried by the frame for holding the lid in its locked position, substantially as described.

6. The combination of the box, the wheel,

the dowel-sockets therein, the washer interposed between the wheel and the box, and the dowels formed on the washer, which fit'into the sockets in the wheel, substantially as and for the purpose specified.

7. The combination of the box, the wheel, the dowel-sockets therein, the washer, the dowels formed thereon, which fit into the sockets in the wheel, and the springs which are attached to the washer and bear against the face of the wheel to hold the washer in position, substantially as set forth.

In testimony whereof I have hereunto subscribed my name this Llth day of September, A. D. 1883.

WILLIAM S. G. BAKER.
