- nupnovnn RAILWAY-CAR muck I The Schedule referred to in those Letters Patent and making put of the lame.
Be it known that I, H. TninLsnN, of Burlington, in the county of Des Moines, and State of Iowa, have in vented certain new and useful Improvements in the Construction of Metallic Railroad-Car Trucks; and I do hereby declare that theibllowiu g is afull, clear, and
exact description thereof, reference being had to the accompanying drawings, making a port of this specification, in which Figure l, sheet 1, is tin-elevation of one end of the 'improved truck, mount-ed upon a track.

Figure 7 sheet 2, is a. perspective view 'of one of the metallic heard-pieces, constituting apart of the supporting-bemns. 7 7
Similar letters of reference indicate corresponding parts in the several figures.
The object of this invention is to improve those parts of a. railroad-cur truck which are employed for sustaining a. car-body upon its trusses, and relieving it from concussions und'undue oscillations, by so constructing them that-they will possess greater strength, duruhilit-y, and lightness than hitherto. The nature of my invention consists?- First, in constructing the horizontal eross-beams upon which the load is supported, as will be hereinafter explained, either of channel-irons, (a, section of which is shown in fig. 6,) or else of wrought-iron plates, arranged edgewise, and stiti'ened by means of angleiron bu rs secured rigidly to their upper and lower edges; and in sect-ring such beams to strong and metallic heudpieces, which are adapted for connecting the beams together at their ends, and securing them to the side trusses of thetruck.
Secondly, in'ahorizontal metallic swing-beam, which is nzude tubular, and in such manner as to afford greet st ength and inficxibility,combined with extreme lightness; said beam being adapted for receiving vertical supports for the trunsoin-slioulder abutments for the springs, and side guides, for preventing forward and backward motion between the cross-beams.
".lhirdly, in a. metallic 'iiu-ngcd transom, which is constructed with f: truss-rib for strengthening it, and also with a central step, which will assist in keeping it in its place, and allow it to vibrate in its socket bearing upon the swing-beam, all as wiil be hereinafter explained.
To enable others skilled intii'e art to understand nny invention, I will describe its construction and operation.
'In the accompanying drawings, I have represented my improved girders, or cross-beams H H, appliedm side trusses LL, by means of strong cast-iron boxes,
or head-pieces K K, which trusses may be applied to the journal-boxes M, on the axles P of wheels N, and constructed in the usual well-known manner, or in any other suitable way. i
Each one of the cross-beams H consists of a thin plate of wrought-iron, which ism-ranged in the truck, so that the whole of the vertical strain is supported by the depth of the plate, or in a direction with its width, rind which is stiffened, so as to resist forward and backward vibration by means of angle-iron bars It 11, arranged along its upper andlower edges, and rivet-ed to it. as shown in figs. 1, 3, and 5.
The beam thus constructed is very light, and also possesses grout strength and rigidity. Being made of wrought-iron, su-y boiler-iron, it will not be weakened by long usage, nor liable to break by sudden shocks.
Each one of these beams may be made of a. single piece of wrought-metal, bent in the form known as channel-iron, as represented in fig. 6, at H, which willrcnder unnecessary the riveting on of the angle-pieces, and possess a. capability of sustaining vertical strain equal, or nearly so, to the compound cross-beam H, above described.
, The cross-beams are firmly riveted to the vertical sides k k of the head-pieces K K, by means of rivets,
which leave a vertical space between the bea'nis, large enough to receive the swing-beam 0, upon which rests the transoui A, us'shown in the druwings'.
The head-blocks, or pieces K, are constructed of reel;- angular form with flanges k k kfl'and central strength-.- euing-(livisions k, as shown in fig. 7, thus adapting these heads to receive on their vertical sides the beams H, and on their horizontal sides the trusses L L, and having the said parts rigidly secured together. In this manner not only the heads K can be secured to the trusses, but the flanges, or angle-irons h h can be securedzit their ends to the trusses.
Within the vertical space included between the crossbecms H H, and their heads K K, is a swing-beam O, which is'so'mewhnt shorter than the cross-booms H, for allowing it to receive endwise'phiy, and which is sustuiued by means of suitable springs E E, upon a horizontal stand-board, F, as clearly shown in fig. '4.
The stand-board F rests upon horizontal swivel-stirrups it, applied to the lower ends of two pairs of haugers G G. I
These hangers are suspended from rods i i, which have their hearings in blocks h ii, that are bolted on top of the cross-beams H H.
The springs E E are interposed between the standboard F and flat-faced bearing 0 c, which are formed on or s flied to the bottom of the swin -.beam as shown in iig. and these springs may be retained in their places by means of'the through bolts, or guidepins 0. This allows the swing-beznn a free elastic play vertically, and also allows it to swing freely in a. direction with its length, to prevent undue lateral motion being communicated to the car-body.
Near the extremities of the swing-beam O, on top thereof, lure the vertical supports 0, for steady-lug the ends of the transom.vertically, and at the middle of the length of this swing-bezuu, and on top thereof, a-circular socket-bearing, 15,'is constructed, for receiving a. corresponding step formed on the lower edge, and in the middle of the length of the trmisum A, as shown in iigs.'4, 5, and'G.
' A hole is made' vertically through the centre of theswing-beam,-ibr receiving the king-boltthat unites the transointo it, which bolt also passes down through whole made through the stand-Marc], as shown in tigs.
' 1', 4,-5, and (5.
The swing-begnn ismade hollow, of cast or wroughtmet-al, and in cross-sectionit may be circular or ellip ticz l, while in longitudinalsection it may taper from the middle" of its length to its extremities. Such a. beam will beyery light, yet possess great strength for resisting vertical strain and shocks.
It is prevented from receiving forward and backward.
or 'lateml play between its beams H H by means of vertical olfsets b b, which slide vertically and horizontally'iigainst. corresponding ,ofi'sets, or guides y g, on the inner suriiwes of the said beams, as clearly shown in figs. 5 and 6. Said offsets will alsosustain the swing- 'of a socket-bearing, B, andbeam aminst rockim about its ion ituinel axis 0 e 5? holding it squarely in its place.
The transom, or bolster A is composed of it single piece of cast-iron, and has a horizontal surface terminoting in flanged edges (1. 60, adapted for receiving bolts through them, for securing this transom to the bed of wear-body. It is strengthened vertically by the tapering or truss-rib a, and it is alsoconstrncted with pendants a, a, which afford slides and abutmcuts for the bearihgs 0,0.
Having described ray-invention,
' 'What I claim as new, and desire to secure byLetters Patent, is-
1. The cross-beams H, composed of plates gu'rauged 1 on edge, stifi'enedoy means of angles along their upas described.
. 5. The construction of 'onepi'ece of metal of a. tran som, A, with flangcs'a,-rili a, and bezu'ings a; substantially as described.
