NVENTOR o WILLIAM H. NUNAMAOHER, OF NEWARK, NEW JERSEY.

Y FREIGHT-CAR.

No. creeis.

To all whomy it may concern.'

Be it known that I, WILLIAM I-I. NUNA- 'MAoiiEia a citizen of the United States, residi-ng in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Freight-(lars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pei'- tains to make, construct, and use the same.

In the present construction of box cars,

ent-ire reliance vis place/l upon. the frame work of the car to prevent distortion and the breaking` out of the ends ofthe car, duc to the shifting of the load. It frequently happens in shunting cars laden with dressed lumber, heavy package freight, and the like, that when such ear is suddenly stopped, as com# ing in contact with another car, or with the bumper at the end of the side track, the mo* mentuni of the lumber, package freight and l the like, is such that it will shift longitudinally of the car and break through the end,

while frequently this sliding motion of the freight, if insuilicient to break the end of the car, will so rack the frame as to necessitate the sending of the car to the repair shop` Where it is frequently out of commission of from two weeks to two months,

My 4invention has for its object, to so.

strengthen and brace the frame work of the car that the above named dilliculties will be completely obviated, and whilel my improvements are of such a nature as to make them readily applicable to new cars, yet they can as readily be applied toccars already in use. In carrying out my invention, l make use of the stiuctures illustrated in the accompanying drawings, which show merely the essential timber work of the car, omitting the side trusses and braces usually present.

' The improvement consists in the series of metallic braces in connection with a sheetnietal car end. y

rchords 1.

' The elements thus described are of the usual and ordinary construction.

I have omitted from the drawings the other wooden braces which are usually pres# ent in the frame work of a box car, the omission being for the purpose of clearness.

Completely spaniiii'ig the end of the car from the top chord to the sills and from side to side, is the large sheet-metal plate 8, located inside of the end timbers, and secured iii position bymeans of bolts. Running diagonalliY on cach side of the car between the upperl end of the corner post 5 and the lower end of the door janib 2, is the metallic brace 9,l the upper eiid of which is bent around and extends between the upper corners of the plate S Aand the end chord 7,`as clearly shown i'ii Fig. 1. The lower end of the brace 9 extends beneath the sill 3 and is lapped aroundthe under side and bolted in position.

Connecting the lower edge of the plate 8 with the longitudinal. car'sills is the angle bar 10, ruiming completely across' the lower edge of the plate and-the car sills. llie angle y plate 10 is rigidly secured to the plate 8 and to the car sills 3 and 4 by means of bolts or rivets 11 as shown.

Extending across between the end posts 5 is the end girth 12 located at the samelieight as the girths 6. Outside of the girth 12 I locate the tension. bar 13, the ends of whicli'lap around the corners of the car as illustrated in Fig. 3, and are secured to the girths- G by means of the bolts 14. The middle portion of the tension bar 1.3 is cambered away from the girth 12 and between such bar and the girth 12, I locate the strut 15. In this manner, I form a very rigid truss for the middle portion f of the'end of .'he car.

Between the plate 8 under the end girth 12, locate the middleportion of the long U- i shaped brace 16, the ariiis N,of which. extend 4along on the inside of the girth 6 with their extremities lapped around the door jambs 2 towliich they are secured by-.nieans of bolts.

located midway of the car body, I provideA page of. the car arid the inertia of the load are eiectually resisted by the two braces 9 and 16.

' In order to forman eil'ective' brace for the upper end chord 7, I provide'the following structure: Between the' upper chords 1 and the tubular carline 17 clearly shown in crosssection in Fig. 4. This earline is made from sheet metal rolled up so as to form the lower tubular compression member 18, with the iin .members 19 shaped to conform substanl tiall `with the inc ines of the-roof. Portions of t e lins 19 are cnt down Aand bent outward'ly as at 20 to receive the longitudinalroof timbers 21 The ends of the carline are -splayed outwardly so as to lie parallel with t le to'p chord and are secured to such top chords by means of the eye-bolts 22. Runni diagonally from the eye-bolts 22 to the mi dle of the end top chord 7 are the .diagonal braces 23, the forward ends of such rods running through castings 24 and 25, which have inclined faces, l'xerpendicular to the axis of lsuch rods 23, so that nuts 26 may be thread- 'ed u on the rods 23 and form an easy means of .at justing the tension in such rods. Without the diagonal brace 23, there might be a tendency for the top chord to fractureunder heavy stresses; the braces 23, however, bein f connected from each end of the car to the middle to the top chords will electuall y obviate this tendency.

In Figs. 1 2 and 3, I'h'ave illustrated about half ofthe car frame. It will be understood, however, that the braces,.end plate and tension members are to be applied to the opposite end of the car in the same manner as illustrated, so .that both ends of the car will be braced alike.

- Changes may be made in the form el structure of the several braces to suit the diile'rcnt conditions under which they are used; for example, the carline 17 may be of any other structure than 'that illustrated, as a plain cross piece of. timber to act as a spreader to prevent the two to) cl'iords from drawing together under 'the longitudinal strain produced by the rods 23. Again, the U-shapcd braces 16 may bc divided and extend only from the end girth 12 to the jalgnb 2, the outer end being bent around beneath the plate S for a short distance u )on the girth 12. 'lhe plate 8 is ofsubstantla-l thicknessand being of tough steel, will not fracture under the heavy-strains to which car ends are subjected, while the diagonal braces f serves to revent any racking or distortion of i ne car rame.

It will be seen that braces and end plates are as readily applicable to cars in present use as to newcars.
