SPECIFICATION forming part of Reissued Letters Patent No. 9,925, dated November 15, 1881, Original Nam-1,801,. dated September 4, 1877. Application lorreissnc'filed Angustlfi, 1851.

To all whom it may concern:

Be it known that I, SUMNER A. Beans, of Springfield, county of Hampden, in the State of Massachusetts, have invented a new and' usefubImproved J ournal-Box for Railway-Car I box is also arranged to hold the brass firmly in its proper position and yet allow it to move with the axle. The box is also provided with lugs below the'axle, which operate to hold thelatter in its proper relativeposition within the box.

It also consists of a projecting sleeve made upon the innercnd ot' the box, with a metallic housing also made upon the inner end of, the box, outside of and surrounding the sleeve, and extending inward in the same direction with said sleeve, the space outside of the sleeve and within the housing surroundin g it being adapted to contain a wood blocking and suitable packing, and to receive an annular flange cast on the car-wheel, said flange being inclosed and protected by the housing. A washer is placed against the end of the sleeve, where it is held by suitable packing placed between it and the car-wheel, and a washer is also placed against a shoulder at the opposite end ofthe sleeve and betwecn'it and the axle-bearin The axle is held securely within the box by a forked key fitting into an annular recess at the outer end of the axle, and also into a vertical recess within the box nearits outer end, all which will be more fully hereinafter described.

Figure I is a halt end view of the box with its end cover removed, showing the axle and key and the position of the box in its jaws when attached to a car. Fig. 11 is a longitudinal vertical section through the box and its attachments at the axis of the axle. Fig. III is a transverse vertical section at the line 0 l t of l ig.'l l. l ig. l V is a plan view of the adletters of reference marked.

justable journal-bearing. Fig. V is a I transverse vertical section of the box through the 'lugs which assist in holding the axle in place.

Fig. VI is. a vertical section through the step, showing the-elongated hole for allowing side movement of the car and springs. Fig. VII is aside view of the holder for distributing the oil to the axle. Fig. VIII is an end view of the same with the material placed therein, and Fig. IX is a front view of the key. v In thedra wings, A represents the box, which is of general rectangular shape and adapted to contain the journal'and its bearings, and having a sleeve, as F, made on its inner end, extending inward toward the car-wheel Gr,-and outside of thissleeve is a housing, as B, also made on the inner end of the box, and also extcudin g inwardiu a direction parallel with the sleeve. This housing is-adaptedto contain suitable wood blocking, as O, whichis secured therein by means of suitable bolts, and the annular flange, as G, cast on the side of the carwheel Gp'rojects into the housing between the wood blocking and the sleeve F when in' use.

A washer, .as a, is placed'upon the car-axle A, and against the end of the sleeve F, and is held firmly in that position by any suitable packing material placed between the washer and the canwheel, similar packing being placed around the sleeve and opposite side of the washer, and also around the end of the flange G, which projects into the housing. It will thus be seen that as the axle between the bearing and the car-wheel is inclosed by the sleeve 1*, and the latter is inclosed by the flange G on the car-wheel, and said flange is inclosed by the housing, thejourual-bearing within the box is most efl'ectually protected from the entrance of dust and dirt at the-inner end of the box, and the dust would be compelled to take a very circuitous route to reach the hearing by enter ing between the car-wheel and the box, even if there were no protcctionof packing. The box A is provided with a recessed part, I on its upper side, which is made concave on its lower side; and 11 represents the brassmade upon its lower side, oi a form to fit the upper half of the axle A, and provided upon its up:

per side with a spherical protuberance of such [00 4s 1 *"andfltwogjaws, P,'extend down vfrom the strap der, 0', in the box, between the brass II and the sleeve F.

The box A is provided with a horizontal partition or web, (1, extending from one end of the,

box to the other inside, and this partition is provided with alongitudinal opening,h, (shown clearly in Figs. III and V,) forming a space, D,

beneath this partition in the box, which serves as the oil-reservoir, and which isfilled, or partially filled, with oil when the device is in use. A spring-holder, made somewhat in the form of a letter V,with an ear,-K bent outward on each side, as shown in Figs. VII and VIII, and containing any material, L, which will readily absorb oil, is inserted into the opening h, and extends nearly to the bottom of the reservoir D, the ear K extending out each side and resting-.uponthe partition (1, as's'hown in Figs.YI and III, the oil-conductor or material L extendin gup and bearing against the axle A, as shown inFigIIILz. 7 -1 W The box A has lugs n cast on the inside and projecting partially beneath the axle A, as shown in Figs.I and V, which'prcvents the axle from having'too much vertical movement in the'box, or the box from tilting upward at the outer end whenever the wheel strikes an, obstruction upon the track. 7 The onter'end of the axle is, provided with an annular'groove or recess, m, (shown clearly in Fig. II,) and a key, k, made forkedand; of I 'sufificient width' to extend from one side of the box to the other, is inserted into the box hetweenthe ribs 1 and l', and astride the axle in the groove m. v

" The tepgMi is made nponthe lower part of the box-A, on eacli jside, which supports the springs O and'th'e strap M, resting thereon,

one jaw on each side of the box A, witha butnper spring, 0, over the box, to break the tforceof any extraordinary jar-of the wheels.

The'holes through the step through which the bolts 9 extend, to hold the springs and strap thereto, are made elongated in the same-direc- 7, tion as the length of the box A, so that as the car'is swayed from one side to the other from side to side, the springs .0 will operate to ease' and somewhat limit such side motion of the car.

When the device isto be set upfor use the proper quantity of packing E isfirst placed inside the annular flange G and the washers placed upon the axle A. The latter is theninserted through the sleeve F and the second washer, 0, placed n pen the axle, and the brass H is then held inside the box, with the spherical part H in th'e recess I in'the upper part of thebox- The axle is then inserted into the box,

with the washer a and the packing E pressed firmlyagainst the end of the sleeve F, theholder K, with the material L placed therein, having been first placed in the openingh through the partition (I, in the position shown in Figs. II and III.. The key is is then inserted between the ribs 1 and l, pushed down astride'the axle in the groove on, as shown in Figs. I and II. The reservoir D is then filled, or nearly filled,

with oil, and the cover N is then secured inplace by the ordinarybolts and nuts, N. .As the car is used the material L, upon which the axle, presses or bears, absorbs a sufiicient portion of the oil fromthe reservoir D and deposits it upon the axle as it is needed and used, the holder by its elastic. earsK always keeping the material L pressed up against the axle and keeping them'in constant contact.

It will be seen that the brass H, having a bearing against the-upper part of the box, in-

side onlyat the spherical part H, is free to inove in any direction, and its; hollow'part, against which the axle has its bearing, is always parallel with the axle, and is'in contact with the axle, and wears equally its whole length. The lugs or also operate to prevent the axle 'from moving away from its bearing in the brass and prevent rattling, keeping'the parts close together and in proper position.

It will be seen that, although the jaws P extend down on each side of the box A,'they are both independent of the box, as the la tter has a longitudinal movement between the jaws whenever the caris inclined to. sway from one side to the other. This is an im-' 'portant feature ot; my invention, as the car is made to ride muclife'asier' and with much less wear between thei'rictioual parts.

The bumper-springzt)", aside from its usefulness in obviating: the jar in running over obstructions, is also "intended to take a'bear- ,-ing on the top of the box A when the car is too heavily loaded, andtherebyprevent the 1 springs 0 from being permanently injured.

Having thus described. my invention, what I claim. as new is- 1. A car-axle box having a metallic housing made on the inner end thereof, and an inclosed annular sleeve surrounding the axle,

- with a space between to inclose a; suitable and sleeve to receive a projecting annular flange made on the side of the car-wheel, substantially as described. 7

3. Inn car-axle box,'a metallic oil-pad holder preventing the oil from getting out'of the box provided-with elastic supportin g-ears, for the end the dust from getting in, substantially as 10 puilpolse'of'keeping the oil-distributinglmatgset forth. ria a ways in contactwith tie jonrna su s 5 stantially as described.
