GEORGE J. HOLTON, OF GALESBURG, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO JOHN N. SHEHI, OF MONMOUTH, ILLINOIS.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 233,152, dated October 12, 1880. Application tiled April 5, 1880. (No model.)

To all 'whom t may concern Be it known that I, GEORGE J. HoL'roN, a citizen of the United States, residing at Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Oar-Axle Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the4 same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart of this specification, in which- Figure l is a vertical longitudinal sectional elevation of a car-axle box embodying my invention. Fig. 2 is a transverse sectional elevation. Fig. 3 is an elevation of the inner side of one side of the box. Fig. 4 is a perspective, showing only the lower part of the box, the upper part and axle-journal removed. Fig. 5 is a bottoni plan of the box, seen from below. Fig..6 is a perspective of the cap or cover. Fig. 7 is a perspective of the packingplates.

My invention relates to car-axle boxes in which means are provided for excluding dust, saving lubricant, and for holdingl the sliding cap or cover open, closed, or partly open; and the invention consists, first, in a novel combination of parts adapted to prevent the lubricant-vehicle coming against the upper and lower sliding plates; second, in a novel combination of parts adapted to hold the brass and also the lubricant-vehicle away from the upper slidingplate; third, in combination with a car-axle box and its sliding cap or cover, a plate attached to the cover and adapted to shield the cap or cover and carry oil thrown against it back into the chamber of the box.

The invention further consists in constructions and combinations hereinafter referred to, and set forth in the claims hereto annexed.

Referring to the drawings by letters, the same letter indicating the same part in the different gures, letter A represents a railway-car axlebox constructed in an ordinary manner, except as hereinafter described. B is one end of a caraxle, with the ordinary journal b, shoulder b', and collar b and O is an ordinary bearing or brass held against movement lengthwisein one direction by a ledge, d, on a plate, D, and in the opposite direction by a plate, E, which is fitted in grooves e in the sides ofthe box A, and has a semicircular groove, c', in its lower side, adapted to rest a short distance above the shoulder b of the axle.

F is a plate with a semicircular groove, f, in its upper side, and its vertical sides fitted between the wall a of the box A, and a shoulder,

f, formed by cutting` away a portion of the box A, so that the plate F may slide freely up and down. F is a spring located beneath the plate F, so as to press it upward against the shoulder b. A slot, g, extends transversely across the bottom of the box A, through which the plate F and spring F may be inserted or withdrawn. The slot g is dovetail-shaped in its cross-section, and is closed by a slide, g', on which the spring F rests when in place.

H is a plate, with its lower side grooved to t the shoulder b', and is seated between the wall a ofthe box and lthe plate E, so that it may slide up and down. The plate H may be inserted and removed through a slot, a', in the box A, and is held to the journal b by gravity. The ends h ot` the plates F and H are rabbeted so as to break joint between them,as shown at Fig. 7.

I is a partition extending across the bottoni otl the chamber in the box A, and located a short distance interior to the plate F, and so as to leave a small chamber, i, between them.

J is a sliding plate, similar in form to the plate F, with a spring, j, beneath it. The plate J rests against the partition I and ledge l on one side and against a ledge, I, and ledge 1" on its other side. Theledge 1" only extends part way down from the top ofthe box, so that by pressing the plate J downward its top may be turned outward to remove it, as shown by dotted lines at Fig. l. The plate J is located so that its upper grooved side is a short distance below the journal b and its lower part a short distance from the partition I, and serves as a shield to prevent the cotton or lubricant-vehicle coming in contact with the plate F. Any lubricant that is forced over between the plate J and journal b will pass down between the plate J and partition I and IOO find its way back into the chamberAthrough a groove or notch, i', in the ledge 1".

With the plates I" and 1I secured as hereinbet'ore described. they may be made ot' wood witholltdanger ot'breakiug,r by the longitudinal movements ot` the axle, and I prefer wood to any other material t'or the purpose. The plate E not only serves as all end support for the brass C and guide and guard for the plate 1I, lult also serves to hold the cotton or other vehicle containin; r the lubricant away from the l plate ll. The plates H and 1 will exclude very nearly all dust, and any small portion that may pass them will be inoisteued and fall into the chamber i, from which it may be removed as occasion requires.

K is an ordinary axle-box cap or cover ot' the class which is fixed iu place and opened by sliding,r in grooves in the side walls ot' the box.

L is a spring-plate, attached at its upper end to the interior side ot' the cap lx', and its lower portion inclined away from the cap, as shown in the drawings. The sides ol'the plate L slide in grooves l in the walls ot' the axlebox as the cap 1i is slid into place, and the plate slightly curved, as shown in the drawings, will cause it to bind in the grooves l sutliciently to hold the eapclosed, and also to hold it when partly opened, so as to nearlyentirely uncover the opening, which it covers when closed. The lower end ot' the plate L should preferably' rest against the end wall ofthe axlebox. Any lubricant which is thrown by the motion ofthe car or otherwise against the plate L will run down and drip t'rom its lower end into the axle-box chamber, and all lubricant be thus prevented l'rom cominglr in contact with and wasting at the sides or ends of the cap K. The plate L maybe made Without 4o any spring;r and formed and attached in various ways, either to the cap or to the box, and may be used without the grooves l.

I claim as new- 1. In combination with the axle-box, axle, slidiiugr plates F II, and partition I, the sliding and vertically-yielding' plate J and plate E, adapted to prevent the lubricant-Vehicle coming against. the plates F H, substantially as and for the purpose specified.

L. The combination, with the axle-box, axle, brass U, and plate H, of the plate D, having,r ledge 1, and the plate E, adapted to hold the brass U and also the lubrieantvehicle away from plate II, substantially as described, and for the purpose specified.

il. lu combination with a ear-axle box and its sliding cap or cover, a plate attached to the cover and adapted to shield the cap or cover and carry oil thrown against it back 6o into the chamber of the box, substantially as and t'or the purpose specited.

4. lu combination with a ear-axle box and l its sliding-cap or cover, a spring-plate attached to the, cap or cover and adapted to shield the cap or cover and slide iu grooves in the side or walls ofthe axle-box, and hold the cap or cover closed, open, or partly' open, substantially as and for the purpose specified.

In testimony whereof I atix my signature 7o iu presence ot' two witnesses.

GEORGE J. IIOLTON. Witnesses:
