OIL-BOX.

SPECIFICATION forming part of Letters Patent No. 626,740, dated June 13, 1899. Application filed March '7, 1898. Serial No. 672,948. (No model.)

T0 all whom, t may concern:

Be itknown that I, EDWIN O. VASHBURN, a citizen of the United States, residing at Minneapolis,in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Oil-Boxes; and I do hereby declare the following to be af ull,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to oil-boxes such as employed in car-axle journals, and has for its object to improve the same in the several particulars hereinafter noted.

My said invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The preferred form of my invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout both views.

Figure l is a view, partly in elevation and partly in central vertical section, showing` an oil-box and one end of an axle constructed in accordance with my invention; and Fig. 2 is a transverse vertical section of the oil-box and axle.y

In accordance with my present invention I provide the axle at a point just inward of its bearing-brass with a plurality of annular grooves, between which is at least one sharp-edged annular ledge or oil-dripping collar, which cooperates with a surrounding oil-groove or catch-channel, which in turn is formed in the oil-box, as will presently be specifically described.

1 indicates the car-axle, which, as is ordinary, is provided at its ends with reduced journal portions 2.

3 indicates the journal-box, which, except as hereinafter noted, is of the ordinary construction and is secured to the truck-frame in the ordinary way. The bearing-brass 4C works on a reduced bearing-section 2 of the axle l and is itself held in the usual way by a lock block or wedge 5 and engages its top and is secured thereby against the top of the box 3. This constructionis such that the axle l is free for a slight endwise movement with respect to the bearing-brass 4L and the journal or oil-box 3. At its upper end, adjacent to the bearing-brass 4, the box 3 is provided with an approximately annular channel a, that extends over the top of the axle and runs to the bottom or lower portion ofv said box. In line or approximately in line with the oil-channel a below the axle the box 3 is provided with a segmental web or cross-bar a,for a purpose which will be hereinafter par- .ticularly noted.

In transverse line with the oil-groove a the axle is provided with several grooves, (as shown t\vo,) which are located so close together and so near to the journal portion 2 as to form a pair of annular flanges b and b'. `The annular flange h, which is farthest from the reduced portion 2, has quite a sharp edge, so that it will afford very little surface for oil to cling to, and hence .will facilitate the discharge of oil therefrom either under the action of gravity or centrifugal force. This flange h is so located with respect to the oilchannel a, that it will always stand in a position to discharge into the same throughout all of the possible longitudinal movements of the axle with respect to the box. With this construction any oil which Works its way over the flange b', which stands closest to the reduced portion 2 of the axle, will run into the first groove, and from thence onto the sharpedged flange b. Now if the axle is turned at a slow rate of speed the oil will, under theaction of gravity, be dropped from the flange b and will run back into the box. other hand, the axle is turned at a very high rate of speed, the oil will be thrown from the iiange Z) under the action of centrifugal force into the oil-channel a, and by the latter will be conveyed to the bottom of the oil-well.

The segmental cross-web a prevents the waste z, which is contained within the oil Well or box, from coming into contact with the Iianges b and h', and thereby prevents this waste from interfering with the throwing or discharging actions of said flanges b and h. Again, this cross web or bar a serves to keep the lower portion of the oil-channel a clear of Waste and open, 'so that .oil may always run to the bottom of the well.

c indicates an ordinary or suitable oil-box lid or cover, which, as shown, is pivoted to a hinge-lug or pin-seat a2 on the oil-box 3 by means of a pin c. This lid or cover serves to close the mouth or opening a3 of the oil-box.

If, on the IOO Well Without necessitating the rel'noval o`f the Waste, the oil-box is provided With an oildelivery channel a4, which leads from the mouth of the opening a3 to the bottom of the box or Well. It will be noted that the upper extremity or mouth of the oil-passage fis Within the oil-box,vso that when the lid c is in position to close the mouth or opening a3 it cuts off access to the said oil-channel d4. This feature is of importance.

oil-channel a4. the oil-delivery channel it is, of course, not necessary to remove the Waste in oilling, nor is it necessary for the oiler to Wait for the oil to percolate or soak into the Waste.

`The oil-channel a4 may be filled with oil the lid c closed, and the oil will gradually distribute itself through the Waste under the lact-ion of capillary attraction and gravity.

6 indicates an ordinary sand-guard. It will of course be understood that minor changes in the specc details' of construczindicatesabody of oil contained Within the oil-Well and the; Vith this arrangement of,

tion above described maybe made Within the scope of my invention.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

l. An oil-box provided with a transverse web or bar extending close to but spaced apart frolnthe axle, the inner Wall and the bottom of said box, for keeping Waste from .contact with the axle, at a point in line with ltheinner Wall of the box, substantially as described.

2. The combination with the oil-box 3 prolvided with the' .approximately annular oil- 3 groove ct andthe transversely-extended Web or bar d spaced apart from the bottoni and side of said box, ofthe axle lv provided with the oil-discharge flange or rib b Working in line with said oil-channel a, substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of tvvo witnesses. n n A EDWIN C. WVASHBURN.
