JAMES MILTON WAUGH, OF CHICAGO, ILLINOIS.

J URNAL-SPRING.

Application filed February 15, 1913.

To all whom it may concern:

Be it known that 1, Jaime MILTON VVAUGH, a citizen of the United States, and

a resident of the city of Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements in Journal-Springs; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

The entire load of the truck, car body and car contents is carried wholly upon the ex tended ends of the car journals in all railway rolling stock. Even under the best attainable track conditions, the inequalities in the track, or flat wheels, are sufficient to cause constant vibration and shock upon the journal and also upon the truck. Such shocks, in the majority of instances, are imparted practically as hammer blows to the end of the journal and the box supported thereon. It is undoubtedly true that a large amount of journal trouble is occasioned more by such shocks and such vibration than by the weight of the load supported thereon, and many railway accidents, with loss of life and large destruction of property annually, are occasioned thereby.

Such shocks and blows, when the journal is at normal running temperature, are destructive, in many cases breaking off the ends of the journals, and when the journal becomes hot, as sometimes occurs, such shocks and blows, if not causing breakage, cause deflection of the journal end, which, even though very slight, renders the journal a constant source of danger, causing frequent heating and delay. The defect can only be remedied by replacement of the journal.

The truck springs, as ordinarily placed, receive and absorb more or less of the shock, but only after the blow or shock has been delivered substantially as a hammer blow from the journal to the journal box, which has heretofore been supported directly and imediately upon the filler for the brass, affording a continuous and rigid unyielding metal contact from the journal to the box, so that the chief utility of the truck springs as Specification of Letters Patent.

Serial No. 748,630.

ordinarily installed, is to cause the load to ride somewhat more easily and to protect the load in the car from the shock due to inequalities in the track, such truck springs having little effect to protect the journal or track (in the event of flat wheels) from injury.

It is an object of this invention to afford a. construction in which resilient means are provided within the journal box to' support the load on the journal, and to protect the track and journal by absorbing shocks, from track inequalities and from fiat wheels, within the journal box.

It is also an object of the invention to afford a construction in which, in addition to the usual truck springs, an additional or journal spring is inserted to receive and absorb vibration and shock within the journal box.

It is a further object of the invention to afford a construction in which a railroad truck, which may be provided with the ordinary or usual truck or pedestal springs of any kind, is also equipped with springs within he journal box and on which the journal box and load is supported upon the j ournal.

it is a further object of the invention to afford a construction wherein a railway journal box of standard construction, is provided in the top thereof with a journal spring, adapted to be supported upon the brass or filler to absorb the shocks imparted to the journal as near as possible to the journal, the ordinary or usual truck or pedestal springs acting to absorb the shocks beyond the capacity of the journal spring.

It is also an object of the invention to afiord a construction wherein the journal spring is maintained in the top of the journal box from displacement while renewing or inserting the brasses or filler blocks.

It is important object of the invention to afford construction in which the load is supported evenly and uniformly upon the journal end for the entire length thereof, thereby avoiding the unequal distribution of pressures on the journal sometimes occurring when a truck is somewhat sprung or distorted, or the car improperly balanced on its truck.

The invention (in a preferred form) is illustrated in the drawings, and is hereinafter more fully described.

In the drawings:

Figure 1 is a central, longitudinal section of the journal box and contents, showing the journal in elevation.

Fig. 2 is a section on line thereof.

Fig. 3 is a front elevation of the journal box with the journal and brasses removed.

Fig. a is a section broken away on line 4-4 of Fig. 1.

Fig. 5 is a similar section on line 55 of Fig. 1.

Fig. 6 is an enlarged end elevation of a filler block such as shown in Fig.

Fig. 7 is a section similar to Fig. 1, and illustrating a construction in which a convex bearing member is supported in the journal 2;) box and affords the lower bearing member for the spring, and rests flat upon the top of a filler block of the ordinary construction.

Fig. 8 is a transverse section thereof.

Fig. 9 is a view similar to Fig. 8, but

showing a filler block having a concave upper surface complemental with the convex under face at the top of the journal box and against which the journal spring bears.

As shown in the drawings: 1, indicates so the end of a car journal, which may be of the usual or any desired construction. 2, indicates the journal box, which may be any desired railway journal box, except that preferably (though not essentially) the top of the journal box at the inner side, is transversely concave, as shown in Figs. 1, 2, 8, 7, and 8, affording a spring recess 3, or convexly curved transversely, as shown in Fig. 9, afiording a convex spring abutment at.

Engaged in the top of each journal box, as shown, is a spring comprising a plurality of fiat spring plates 5, of a length corresponding approximately with the length of the journal bearing, and of a width to extend a from side to side of the journal box on its inner side, and above the vertical ribs 6, one of which is located in each side of the journal box at about its middle to reinforce the same around each of the bolt apertures, as

is usual, and secured on each of said ribs near the top thereof, and assisting to retain said spring plates in position, are steps 7, which extend downwardly and serve as spacing members at each side of the brass filler block.

The brass 8, is any standard or preferred journal brass. Supported thereon is a filler block 9, which, as illustrated in Figs. 1, 2, and 6, is convex transversely at its top, the

curvature thereof corresponding approximately with the concave curvature in the top of the journal box, so that the flat spring plates rest thereon longitudinally thereof directly above and along the axis of the journal, the ends of said spring plates engaging in the top of the journal box at the extreme sides thereof, as shown more plainly in Fig.

' 2. If preferred, however, instead of using a special filler blockthe ordinary fiat top bearing block 10, may be employed and a bearing member 11, having a convex upper side,

is inserted thereover, as shown in Fig. 8, resting flat thereon, and the convexity thereof corresponding with the curvature in the top of the journal box, and supporting the spring thereon, as before described, with reference to Fi 2. Of course, if preferred, the convexity maybe provided in the top of the journal box, as indicated at 4-, and the filler block 13, concave on its upper side, may be employed, or if preferred, a concave spacing or hearing member may be provided to rest upon the top of an ordinary filler block and to engage the spring at the extreme sides of the journal box somewhat as illustrated, with the convex bearing member shown in Fig. 8. Preferably, the springs are assembled in the journal boxes at the factory, and are retained in place by stops 7, which engage beneath the ends thereof, as shown in 00 Figs. 2 and 9, or. if a bearing member be employed the bearing member may be inserted with the spring above said stop 7, to

be retained in place thereby, said parts being assembled to slightly tension the springs to hold the same from displacement during shipment.

The operation is as follows:

The springs usually employed in a truck, operate, of course, as such springs usually do in absorbing track shocks and stresses, and in addition thereto, the journal spring within the journal box serves to yieldingly support the journal box and its load upon the journal, so that track shocks are immediately absorbed thereby between the journal and the top of the box. The resistance of said springs is su'iiicient to yieldingly support the load without material deflection of the springs. Said springs, however, af- 1119 ford a yielding and resilient member between the journal and the journal box, which serve to absorb shock, not only because of the resiliency of the spring, but as well because of the frictional engagement of the spring 5 plate face to face.

Such resilient, frictional absorbing member acts, of course, to protect the rolling stock from injury, but what is equally (if not more) important, greatly reduces the shock imparted to the rails during the passage of the train thereover. Such shock absorption reduces the tendency of crystallization of the rail and obviating, in a large meiisure, expense due to breakage of the rai s.

It is to be understood, of course, that I have shown but a preferred construction embodying my invention, and I do not purpose limiting the patent otherwise than necessitated by the prior art, but purpose claiming broadly any construction wherein a shock absorbing member is disposed within the journal box to support the load upon the journal.

I claim as my invention:

1. In a device of the class described a journal box, a curved filler block therein, a journal, a journal bearing mounted thereon supporting said filler block, and resilient flexible shock absorbing means inserted between the filler block and the journal box acting to absorb shocks from the journal bearing.

2. A device of the class described embracing a journal box, a filler block having a convex outer surface, a bearing brass supporting said filler block upon an axle, and a group of separable resilient friction plates supported 011 said filler block and acting to support said journal box thereon.

3. A device of the class described embracing a car journal box, and journal bearing members, said box and one of said members having adjacent surfaces complementally curved, spring friction plates inserted between said curved surfaces and held in position thereby, and means on the journal box to limit lon itudinal movement of the I I b a journal bearmg members therein.

a. A device of the class described embracing a journal box, a journal bearing brass therein,'spring friction plates engaged within the journal box and acting to support the journal box on the journal bearing brass, said resilient and friction members engaging one of said elements at its ends and bear- Gopies of this patent may be obtained for five cents each, by addressing the ing against the other at its middle, said elements being complementally curved to afford equal cushion space on each side of the journal members.

5. A journal box of the class described transversely curved in its top at the under side thereof, a journal brass filler block therein, and spring friction plates permanently engaged in the top of the journal box and bearing on the journal brass filler block, said filler block being transversely curved 011 its upper face complementally with the curvature in the top of the journal box.

6. The combination with a railway truck, of journal boxes and journals, a journal brass on each of said journals, the usual truck springs, of a group of separable resilient friction plates in each of'the journal boxes supporting the same with its load on the journal brass, the line of bearing thereof both in the journal box and on the journal being parallel the axis of the journal.

7. The combination with a railway truck and its springs, of journals, journal boxes therefor, a journal brass and filler block on each of said journals, groups of resilient frictional shock absorbing plates of equal length yieldingly secured in each journal box and acting to support the load directly upon the filler block of the journal brass.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
