To all ill-11. 0111, may concern.-

Be it known that 1, JOHN F. (.lCoinqon, 2i citizen of the U nited. States, residing in Chicago, in the county of Cook and State illinois, have invented a new and useful linprovemcnt in Railway Dre-1 Rigging for Tenders or other Cars, of which the following is e specification.

Ixiyinvention relates to improvements in draft-rigging for railway-tenders or other cars, and more particularly to the improveinentsinthe construction of the shop-misting on the draft-rigging for railway-tenders or other cars in which the stop-casting is composed. of single piece extending between the sills or frame-pieces of the canto which the draft-rigging is secured.

As is Well known, the stop-cestings of railwaydraft-rigging are subjected in practical use to enormous blows, shocks, or strains, and heretofore greet clifiiculty has been experienced from the rlrsit-i'i ging breaking or giving away, and especial y at the points where the steps or shoulders, against which the followers clout, join or unite with the main body of the casting. Heretoiore railway stop osstings have" usuallyvsried very greatly-in thickness at d:L"-- ferent parts of the casting, and especislly at me intersection of the stops or shoulders with the main bogiy of the casting, from which said shops or shoulders project. According to my observation. she breakage most frequently occurs at such inset-sections where the es ring is of a f-osotion and Where an increased bodyof mete-l. or increased This (lifiiculty or hreekl have discovered is very lr-rgely due to clef-eels, blowholes, castinq strains, or other unequal cooling and contraction, owing to the unequal body of metal end unequal thickness in dii'ierent parts of the casting The ohject of 11:57 invention is to provides. one-piece railway draft-rigging stop-casting suitable for use upon tenders one other cars which will obviate the difliculties heretofore experienced and which will he of a simple, strong, efficient, safe, and reliable construction and capable of successfully withstanding the strains anal blows to which the cirsfi rigglng is subjected in actual emetic-cl use.

My invention consists in the 1-. sons 1 e111- of the casting, the convolutions being trans-- factors the slopes/s ploy to practically accomplish this object or result thstis to say, it consists, in connecties. with the drew-her, springs, followers of'the limit-rigging, 0: a one-piece o zast-ing, in sale as usual of malleable iron or other annealing nietzil and provided with a plurality of steps or' should s for the followers 20 shut against, and Whi h is composed throughout of s oas s web of uniform i'l'iiclniess both at the stops or shoulders as Well as elsewhere, so that the stop-casein es sv whole will he of unil'ormjthickness an" entirely free from T-eeotions or other seetions that would result in giving the casting a, greets" thickness or body of metal at some points ftlien others, with the consequent im pei'i'ections, casting strains, and defects which have heretofore been inciuent to the making or" stop-castings of the old construcsions, wherein the steps or shoulders form right/angle or T sections Witht-hemeinhody of the cast rein which they pro ieot.

In practicing my invention the stop-shook ders are formed on the stop-casting by infogrel bends or co'nvolntions in she main web verse to the lengon of the casting the bends or convoiutions being continuous and. without producing any increased thicknees. in mein webof cestii st any point.

My in! h H '0 consists in the novel construcion pa. anal devices and in the novel combinations of aris and devices .eein shown e115 describe By my invention i am on not only a In All siren" casting and (lief than fore use, but i e soled'to menuv'ei: much cheaper, as by my inven'bi-o' scarcely any defective castings are pronlueerl, Whereas in making the stop washings heretofore in use there has always be :3.- very heavy percentage of castings first in test; have to be broken up and rejected unlit for use.

In the accompany drawings, forming a partof specification,Figure 1 is n side elcvction, "psi-fly T vert cal lcngilu-flinol section, of din horlying my invention. Fig 2 is n w (lilOI'l on line an l J, 2 or 21%.}, section .i.- a 'lin fine drawing. A moiesenismue centres sills or frame-pieces of the tender or car to which the draft-rigging is to be secured; A, the end sill; B, the draw-bar; C C, the springs, and D the followers.

F is the stop-casting, the same having a main web F of substantially uniform thickness throughout, the stop-casting fitting and. extending between the sills A A, to which it is secured by bolts or rivets a. The main web F of the casting is of an inverted-U form in cross-section and comprises outer limbs f f, which fit against and are secured to the center sills A A, and an integral invertedportion or member comprising the inclined limbs f, the upright limbs f and the horizontal limbf all said parts f, f f and f being in .one' continuous web of substantially uniform thickness, as will be readily understood from 2 of the drawings The main web F of the casting is also furnished with a plurality of transverse integral bends or convolu tionsf 4 f forming integral. stops or shoulders f f for the followers to abut against. The single-piece casting F thus has a plurality of longitudinal bends, folds, or convolutions, which give-its main web a general inverted-U form in cross-section, and also a plurality of transverse integral bonds or convolutions, which form the stops or shoulders for the followers to abut against, as well as the intermediate shoulders to limit the compression of the springs, while at the same time the main web F of the casting of substantially uniform thickness throughout its entire extent, so that the casting may be readily, conveniently, and perfectly formed without danger of producing blowholes, defects, casting strains, or other Weaknesses, and. at the same time my improved stop-cast ing is given an. exceedingly strong and. rigid form and construction, as will be readily understood from the drawings,

I claim- 1. In a draft-rigging, the combination with the draw-bar, springs and. followers, of a one i l l piece stop-casting comprising a main cast web. of uniform thickness throughout free from T and other flange-like sections, and having a plurality of longitudinal convolutions and a plurality of transverse convolutions to form stops or shoulders for the fol lowers to abut against, substantially as specified.

2. A one-piece stop-casting for railway draft-rigging, consisting in a continuous cast. Web of substantially uniform thickness free from T and other fiange-like sections furnished with longitudinal convolutions, and with a plurality of transverse convolutions to form stops or shoulders for the followers to abut against, substantially as specified 3. A one-piece stop-casting for railway draft-rigging, consisting in a continuous cast web of uniform thickness free from T and other flange-like sections provided with a plurality of transverse convolutions to form stops or shoulders for the followers to abut against, substantially specified.

4. A one-piece stop-casting for railway draft-rigging, consisting in a continuous web of uniform thickness provided with a plurality of transverse convolutions to form stops or shoulders for the followers to abut against, and provided also with intermediate convolutions to limit the compression of the springs, substantially as specified.

5. A one-piece stop-casting consisting in a i continuous single-piece web having upright outer limbs f, adapted to fit against and be secured to the car-frame sills or pieces, and integral inclined members f, integral upright members f and integral horizontal members f", said web being also provided with transverse convolutions to form steps or shoulders for the followers to abut against, substantially as specified;
