For the purpose of disclosure, two embodiments of the invention have been chosen for illustration and speciilc description, but the scope of the invention is not limited to theseembodiments and the appended claims should be construed as broadly as the prior art will permit.
The recent trend toward increased speeds in railway transportation has resulted in the development of light-weight streamline trains, usually powered by internal combustion engines which drive generators for energizing electric traction motors carriedon the car trucks. The streamline form of the cars has necessitated some changes in conventional car building practice, and one example of body framework which is suitable for cars of this type is shown in Fig. 1.
The main framework comprises a center sill I0, end sills II and I2 secured to opposite ends of the center sill, door end posts I3 and I4, and,
I5 and I6, rising from the end sills II and I2, respectively, anti-telescoping plates I1 and I3 supported by the door end posts, and top sills I3 and 20 connected by plates 2| and 22 to form a box girder which rests upon'and is secured to the anti-telescoping plates I1 and I3 and *the door end posts I3, I4, I5 and I6. Preferablythis portion of the car framework is designed to carry the major portion of the car load.
The shell of the car i's formed by a plurality of ribs 23 which connect the top'sllls I3 and 20 with the upper part of the center sill I0. These ribs lie in vertical planes and are connected together'by various longitudinal framing members, such as rof stringers 24, window header stringers 25, belt rails 26, side sills generally designated 2l,
and various floor stringers. The ribs when made in one piece, as shown in Figs. v1, 2'and 8 serve as combined carlines, side posts and floor supports, but in some cases, it is Ydesirable to form the side posts and floor supports in two pieces, as shown in Figs. 3, 6, and 7.
The vbelly of `the car is formed by arcuate J-bars 28 which connect the side sills 'to the bottom of the center sill. The J-bars are reinforced by struts 23 and 33. f
Referring nowto Fig. 2, the side sill21 is in one piece and is preferably made of aluminum or aluminum alloy formed bythe extrusion'proc ess. The side sill has a relatively deep body portion 3l which furnishes suiiicient resistance lto vertical deflection and is provided with longitudinal insets 32 and 33 adjacent tothe top and bottom edges ofthe sill. These insets are adapted to receive outside sheathing plates 34 PMENTv OFFICE and 35 flush Withtheexterior face 36 of the side f sill, as best shown in Fig. v2. Thetop portion of the side sill is further inset as shown at 31, so that the rivets 33 which secure the ribs 23 to the side sill are covered by the outside sheathing plate 34 (see Fig. 2). The vinsideface 39 of the top inset is slightly concave to conform to the curvature of the rib 23.y Rivets 40 secure the sheathing plate 34 to the extreme upper edge of the side sill, and rivets 4I do likewise, but include also the rib 23 and provides a suitable surface for riveting, the rivets being indicated at 45. In addition, the flanges 43 and 44 serve to materially increase the stiffness of the side sill and particu'- larly to resist bending caused by side impact against the car.
The side sills are connected to the end sills in a manner best shown in Fig. 1Q .i The end sill casting has a lug 46 which ,fits into the recess formed by the shoulder 41 of the inset 31 and the flange 43, and rivets 46 secure the two members together.
'I'he cross sectional shape of the side sills 21 in both embodiments of the invention, exemplifled by Figs. 2 and 3, resembles the lower case Greek alphabet letter lambda, as best shown. in Figs. 11 and 12 (the cross sections representing the side sill on the right hand side of the car when looking toward the end sill |21 in Fig. 1).
The side sill shown in Fig. 3 differs slightly from the one shown in Fig. 2 and is used when the ribs 33 are broken at the side sills for economy of manufacture.
As shown, the side sill comprises a body portion 50- and an inwardly extending inclined flange 5I, the body portion being somewhatthicker and not as deep as the side sill shown in Fig. 2. As before, the -side sill is in one piece and is preferably an extruded aluminum or aluminum alloy member.
When this form of side sill is used, the side post section 52 of the ribs 23, and the cross supports 53, are joined to the side sill and to each other by splice plates 54 and 55, the outside flanges 56 of the rib sections being cut away, as indicated at 51, 56 to accommodate the splice plates. The plates are provided with flanges 59 and 60, the former providing a suitable surface for riveting to the side sill with rivets 6I, and the latter provlding a bearing surface for the floor stringer 62 riveted to the splice plates `at 63V and 64. Rivets 65 secure the side post sections 52 to the splice plates and rivets 66 secure the floor support sections 53 to the splice plates.
The body portion 50 of the side sill has longitudinal insets 61 and 66 to receive the sheathing plates 34 and 35 ush with the outside face of the side sill, rivets 69 and 10 securing the sheathing plates and the splice plates to the body portion of the side sill.
The side sills of Figs. 2 and 3 are both relatively simple to form, particularly when made of aluminum or aluminum alloy and extruded. The same, or similar forms, however, may be made by casting or rolling, and material other than ed to be connected to the sheathing extending beneath the car.
2. A one piece side sill having a relatively deep body portion and an inwardly extending flange arranged at an acute angle to said body portion adjacent the lower edge thereof, the upper edge of said body portion having an inset extending in the direction of said flange.
3. Foruse in a railway car including body framework and sheathing over the framework. a one piece side sill formed by extrusion and4 comprising a relatively deep body portion, and an inwardly extending flange, said body portion having longitudinal insets -along its top and bottom edge adapted 'to receivethe outside sheathing of the car flush with the outer face of the side sill.
4. For use in a railway car having side posts and transverse floor supports, a one piece side sill having a. body portion adapted to be secured to the side posts, and an inwardly extending flange adapted to support the transverse oor supports and act as a stiffener for resisting side impacts,A the upper portion of said body portion having an.
apertured inset for receiving an attaching rivet.
5. For use in a railway car having side posts to which outside sheathing is applied, and transverse floor supports, a 'one piece side sill having a body portion adapted to be secured to the side posts, and aninwardly extending flange adapted to support the transverse -floor supports and act as a stiffener for resisting side impacts, said body portion having 'longitudinal insets" adapted to receive the outside sheathing flush with the exterior face of the side sill..v
6. For use in a railway car having side posts, transverse iloor supports and curved belly forming bars, an extended one piece side sill having a rigid body portion, the top of which'is adapted to be secured to the 'side posts and the bottom to the belly forming bars, and an' inwardly extending flange adapted to support the transverse floor supports and act as a stiffener for resisting side impacts. v 1. In a car body having side posts, sheathing secured to the outside of said posts, a sidesill comprising a. rigid member secured to said posts on the outside thereof and an inwardly extending member for attachment to transverse floor supporting means, and means for securing said sheathing to the upper and lower portions of said sill, the intermediate portion of said sill constituting a continuation of theouter surface of said sheathing. i
8. For use in a railway carincluding a body framework including posts and transverse floor supports and sheathing members over the framework spaced vertically apart, a side sill for bridging the space between the adjacent edges of said sheathing members, said side sill having insets or rabbets extending longitudinally of the sill along its upper and lower edges on its outer side for receiving the adjacent edge portions of said sheathing members flush with the outer face of the side sill, and means for securing said side sill to said posts and to the transverse floor supports.
