CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 564,856, dated July 28, 1896.

Application filed July 27,1895. Renewed June 13, 1896. Serial No. 595,498. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT AUGUST WEBER,

a citizen of the United States, and a resident of San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Car- Axle Boxes; and I do declare the following to be a full, 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, reference being had to the accompanying drawings, and. to figures of ref erence marked thereon, which form a part of this specification.

Figure 1 is a central vertical section through car-axle box with invention applied thereto, brush and actuating parts being shown in full. Fig. 2 is a section on line x a, Fig. 1. Fig. 3 is a section on line y y, Fig. 1, capplates 17 and 18 removed. Fig. at is a front view of one of yokes. Fig. 5, is a similar view of the other yoke. Fig. 6 is a rear view of yoke shown in Fig. 5. Fig. 7 is a plan view of axle-box, cap-plates, and top spring 20 removed. Fig. 8 is a perspective view of capplates fastened. Fig. 9 is a perspective view of box-cover.

This invention is designed to provide a dust-proof car-axle box; and it consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, the numeral 1 designates a car-axle box having therein a lubricant-chamber 2 and a brass or bearing 3 for the car-axle 4. 5 is the cover of said box, which is formed at its upper edge with a beveled inclined flange 6, which engages over a beveled rib or flange 7 on the top of said box. Near the lateral edges of the cover on its inner face are secured strips 7 which fit neatly within the opening in the end of the box, while the marginal portions 8 outside of said strips seat neatly upon the inclined ends of the lateral walls of said box. Between said strips 7 near the bottom edge of the cover, is a transverse strip 9, whose lower edge is beveled, as shown at 10, to form with the cover a seat to receive and fit closely the bottom beveled edge 11 of the opening in the box. The object in view in the abovedescribed construction of the cover is to secure a perfectly close fit which will prevent dust from entering the box and the lubricant from escaping therefrom.

The inner end of the box is formed at its lateral edges with the projecting flanges 12, which form between them a seat for a gasket or packing device of the construction now to be described. This gasket consists of two plates or yokes 13 of similar form, having each the approximately semicircular bearing 14 and block 15 secured thereto. These two plates 13 are applied to each other reversely, the arms of one piece fitting neatly the lateral edges of the block 15 of the opposite piece, with the two semicircular bearings 14 uniting to form a complete bearing which is de-. signed to fit neatly the axle 4.

16 designates two springs,which are secured one to the face of the yoke piece or plate 13 nearest the car-wheel and the other to the block 15 of the other of said pieces or plates. These springs are engaged by the sliding cappieces 17 and 18 to press the two plates or pieces 13 into close contact with each other and with the seat. 19 designates similar springs,which are placed at the lateral edges of the gasket and against the inner faces of the flanges 12. 20 is a spring which is secured to the upper edge of one of the yoke pieces or plates 13 and which is engaged by the horizontal flange 23 on the upper edge of the cap-plate 17 to hold said piece or plate in close contact with the axle. are formed at their lateral edges with guideways 21, which slide upon ribs or guides 22 of the flanges 12. Each of said plates is cut away at 22 to fit the axle, and the said flange 23 of the upper plate 17 fits over a dust-strip 23, secured to or formed on the top of the box.

24 designates suitable fastening devices, by means of which said plates 17 and 18 are secured to each other.

25 designates a lubricating-brush whose shaft 26 is journaled to rotate in lugs 26* of a slotted plate or bracket 27, which is fastened to the bottom-of the box underneath the car-axle and its brass by means of a bolt 28, which engages the slot, of the plate and is secured by a nut 29 upon the outside. On

Said cap-plates ICO the outer end of the shaft 26 is fixed a ratchetwheel 30.

31 is a lever which is fulcrumed at its lower end upon a pin or stud 32 of the plate or bracket 27, and whose upper portion has an elongated slot 33, which engages a wrist 34 on the end of the car-axle. Carried by a stud of said lever 31 is a pawl 35, which is held in engagement with the ratchet -wheel by means of a spring 36. 37 is a gravity-pawl,

which prevents said ratchet-wheel from turning backward.

It will be readily understood that the rotation of the car-axle will, through the wrist 34c, actuate the lever 31 and pawl to cause a step-by-step rotation of the brush 25. brush takes up the lubricant in the chamber 2 and applies it to the surface of the-caraxle, thus keeping the latter properly lubricated so long as anyoil remains inthe said chamber.

Thefeature of the -slot,which is engaged by the bolt 28, not onlypermits the proper a'dj-us'tn ent of the brush with relation to the axle-journal, but l'U"kl;lSO p6I1I1ll)S'tlIe bracket 2-7 to bemoveden d'wise toward the outer end of the box, where the brush-shaftcan be'lifted out of bearings and a'n'ew brush put'i-n.

Inasmuch as the brushes becomeworn or unfi t for use after some time, is desirable to renew them, and'werefthe bracketfixedunderneath the axle-j ournalit'wouldnot be an easy matter to do thisthroug'h the opening in the outer end of the box; bu t-b'ythe provis'ionof the slot this can be readily accomplished.

The bracket may a'lso be moved in .thisman- This ing in its inner end and the projecting flanges 12 at the lateral edges of said end, of the gasket or packing device seated between said flanges, and consisting of two similar plates or yokes 13, applied to each other reversely and cut away each to form an approximately semicircular bearing-openin g 14 for the axle, and a block 15 secured to each of the said pieces and engaged by the cut-away portion of the opposite piece, the sliding cap-plates 17, 18, springs 16 seated between said capplates and the plates 13, springs 19seated between the lateral edges of the said plates 13 and the flanges 12, and a spring 20 secured to the upper edge of one of the plates 13, and engaged by one of said cup-plates, substantially as specified.

In :a dust-proof car-axle boxgthe combination with the box having an 'openimgin'its outer end, the lower edge of said opening having an outwardr'and downward bevel, rand a beveled rib 7 secured transversely across the upper edge portion of the said opening, of =the-cover 5 for the said opening, said cover having on its upper edge a beveled, inclined flange '6 which engages ever the beveled 7.,.and near each latera il edge fa strip which fits within the said opening, and theit-ra-nsverse strip 9 which is securedto'the lower im ner portion of said -cover between the strips 7, and which is beveled on its lower-edge to form with the 'lower-'edge;portion-of '-th'e cover a seat :or groove which receives the beveled lower edge of the :said opening subs'tantially as specified.
