CA3 SIDE CONSTRUCTION.-

Application filed August 29,1924. Serial No. 734,842.,

My inventionrelates to improvements in is car side construction.

It is an object of my invention to improve the construction of car sides formed of trussed construction and especially in the lower chord thereof. 5 It is another object of my invention to secure in a car side truss lower chord which, will be disposed partly above and partly. be- 1 low thefloor' line of the car. It isalso a particular object of myinven. tion to secure in a car side-truss. a lower, chord which will beadequately anchored to the transverse members of the underframe andwherein the lower margin thereof is of great strength' and rigidity to prevent buckling. i

It is also a particular object of the invention' to formin-a car side truss the lower chord of two members and secure the same together thereby providing a truss, the lower partof which is of thicker material than the upper part thereof.

Further, my invention resides in certain improvements and details of construction such as will more fully appear hereinafter in the specification andjclai'msif In the-drawing, Figure 1 is side, elevational viewot one-half of a car showin my improved construction, the other end of the car being a counterpart" of that shown.

Figure 2 is a vertical, transverse, sectionalfp view showing ion an enlarged scale that portion 01. the, car construction which illustrates v connection thereof with one ofthe transverse; members, said sectionbeing taken on a line" corresponding substantiallyto theline 2 2 ofFigurel.

In said drawing the car is shown, to include the side truss A, only one-halter the same being shown, as will "be understood, floor B, transverse beams 0, body bolster D,-

and end walls E. The side truss Act the car consists ot vertical stakes 10 and corner" bands 11, upper chord l2jpreferably con sisting of a, bulb angle member and lower.

chord 18 preferably formed as indicatedof two members 14 and 15' suitably riveted together at intervals by means of rivets 16, the lower of said members 15 is 'oi' angular shape and preferably consists of a bulb angle member having one flange 17 in engagement with the horizontal flange 18 of-ijthe curing a suitable connection with the car un derframe. Above the member 15 andrest the construction of'the lower chord'and the transverse beam C and having the adjacent flange lfldwehdifi wnwa d y v ic ly. wit et p f hate n r q llfl i l cured to the vertical flange 20,- of the said 7 vnsve se be m, The. v ti lfle g 19 ha the; 1ower margin thereof formed ,with a to short ii -turned heavy flange 21 which conu s. the b lb por ion o e ul -E angle member 15. The beam O has a recess or, cut-awayportion 22 adapted to receive the saidbulb; portion -.2l 'an'd to compensate for h .v ress an. e gle employied c ni ,necting the stake 1O and the transverse beam (l the stakes 10;,being extendedbelow the level of the truss A, for the purpose jof see ing on the same is theangle. member hi .which ispreferably formed with a long ver: s

tical flange 24 which, extends upwardly e t e f o ine,., hi1 e e jacent a ge 25 is securely riveted to the fiangel'? of the bulb angle member by the rivets as heretofore described and also by rivets whiche xs tend through the'flfiange 180i the beam C. The two members 14 and 15, thus together form a strong member of considerable, depth to, which the loweriportion of the diagonal members 26, 27,, 28 and 29 are secured both directly by means of rivets as indicated at- 30,,and by means of securing means 81"ex f i tending jthroughthe verticaljstak'es 10. A

referred mannerof constructing the truss is to extendthe lower portion of the diagonal i members, asindicated ;'at 32, somewhat belowf the level of the bottom chord and connect suclrportion with the downwardly eX-, tending, port-ionof the side stakes 10. The 7 "connectionsofthe upper portion of thediagonal members 7 and vertical stake may be carried out ,in'theusual manner common to thistypefof truss and ,as showrr on the drawing. i i

The upper flange member 14 of the truss formsia conveni'entsupport forthe floor Y B and the sideplanking 2330f thecar. The 10 double horizontal ,flange. of the lower truss member as provided by thetwo members 14 and To -forms an especially. suitable lower chord for a 'car of the type shown, which is or the dump car type. The outer end of vthe floor door shown at V3 iis adapted to be raised and lowered by means of the operating shaftz35, suitable connecting nieansbeing. provided between the shaftand doors, as shown conventionally aatl,36. On such cars, mainly due to a large portion of the floor area being devoted to dump doors, there is a tendency for the car to rack, and the use of a strong member suitably anchored at the floor line in the manner shown becomes of the greatest importance.

The combination of the two sections 14 and 15 in effect provides a lower side mem her which is substantially of T-shape and with the double flanges disposed substantially at the floor and united to each other and to the transverse beams, these sections serve as a column of great strength to sustain the racking strains to which the car is subjected in addition to the function which they exercise as the lower chord members of the trussed sides.

WVhile I have shown the lower chord member in two pieces, it will beevident that the equivalent of the two sections would be secured by a rolled unitary member, and I wish to include all constructions which come within the scope and spirit of the claims appended hereto.

What I claim is:

1. In a railway car, the combination with the transverse members of the under-frame; of a trussed side including an upper chord, a lower chord, Vertical members and diagonal members, said vertical members and diagonal members being extended downwardly below the lower chord and secured to the transverse members of the underframe and to the lower chord, said lower chord having a horizontal flange in engagement with the cross-beams and having vertical portions extending above and below said horizontal flange.

2. In a railway car, the combination with the floor of said car; of a trussed side including in its lower chord two angularly shaped beam members having horizontally disposed flanges placed back to back and arranged to support said floor, one of said members having its vertically disposed flange extending outwardly of said trussed side and said floor, and the other of said members having a flange extending below the trussed side, said latter flange on its lower extremity being provided with a bulb formation.

3. In a railway car, the combination with the transverse beams; of a trussed side including an upper chord, a lower chord; vertical and diagonal members secured to said upper and lower chords, and to said transverse beams, said lower chord comprising two angular beam members having angular portions extending on the outer side of said trussed side, and connected to said vertical and an angular portion extending below said trussed side, said latter angular portion being provided with an excess of metal along its lower extremity.

4. In a railway car, the combination with transverse beams; of a truss side including a lower chord formed of two angle bars extending longitudinally the full length of the car side, and each having a flange arranged in horizontal position and disposed back to back with reference to each other, and having vertically disposed flanges extending in opposite directions in a common vertical plane, the lower of said vertical flanges being reinforced by an outstanding marginal portion of less extent than the remaining flanges of said chord, the horizontally arranged flanges being disposed inwardly with reference to the car side, the combined vertical width of said angle bars forming a lower chord of restricted depth below the floor of the car as compared with the depth of said transverse beams.

5. In a railway car side, including fabricated elements forming a truss having a lower chord comprising two angle-shaped beam members united together and extending longitudinally throughout the car side, one of said members being disposed above the other with their vertical flanges superposed in a common vertical plane, the lower beam member being in the form of a bulb angle member, said trussed elements being secured to the vertical flanges of both of said members.

6. In a railway car tru-ss'side, the combination with the diagonal and vertical members of said side; of an upper chord; and a lower chord, said lower chord being formed of two vertically superposed angle bars, each having a flange inwardly disposed with reference to the truss side in a horizontal direction, and being placed back to back, the vertical flange-s of said members being superposed in a common vertical plane, and the lower of said vertical flanges having a bulb formation forming the extreme lower margin of the lower chord, said diagonal and vertical members of the trussed side having their lower ends overlapped and secured to the vertical flanges of both of the angle bars forming the lower chord.

7. In a railway car side, havin vertically and diagonally disposed trussed members and a lower ch ord, the latter being formed of two angle-shaped members secured together, one of said members beingdisposed above the other and the lower of said members consisting of a bulb angle bar with the bulb portion thereof defining the lower margin of said chord, the lower ends of said trussed members being arranged in overlapping relation with each other and secured to the vertical flanges of each of said angleshaped members.

8. In a railway car, the combination with a transverse beam, of a car side including: an upper chord, a lower chord and vertical stake members secured to said upper and lower chords and also to said transverse beam said lower chord comprising two angular members placed back to back and having adjacent flanges horizontally disposed and secured to each other and to the transverse beam, the upper of said angular members having a vertical flange extending up- Wardly above the top of the transverse beam and the other of said members having a vertical flange extended downwardly, said last named flange being provided With an excess of metal along its lower extremity, the vertical stake member being secured to the vertical flanges of both members and extended for an appreciable distance below the said extremity and secured to the transverse beam member.

In Witness that I claim the foregoing I have hereunto subscribed my name this 18th day of August 1924.

ARGYLE CAMPBELL.
