HENRY C. IICDGES, OF DETROIT, MICHIGAN.
CAR CONSTRUCTION.
SPECIFICATION forming part of Letters Patent No. 468,176, dated February 2, 1892.
Application tiled August 28, 1891. Serial No. 403,958. (No model.)
To all whom t may concern:
Beit known that I, HENRY C. IIODGES, a citizen of the United States, residing at De troit, county of Vayne, State of Michigan, have invented a certain new and useful Improvement in Car Construction; andI declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specication.
This invention has for its object the construction of cars and similar structures where great length of frame is required and where the entire structure must be supported on few points; also, where destructive strains are brought about not only by a proper motion or draft in hauling, but by concussion of sudden stopping or collision.
The requirements of modern commerce make it necessary to employ cars of large carrying capacity, of great strength, and of considerable weight. It is desirable that capacity and strength be increased without a corresponding increase in weight.
The only practical way to increase the ca-` pacity of a railway-car is to build it longer, as both width and height must conform to adopted standards. Vhen, however, the car is lengthened, the frame must be strengthened without a corresponding increase in weight. I attain this result by the use of a frame-work constructed in accordance'with the following specifications, and illustrated in the accompanying drawings.
Figure l shows one end of a floor-frame, showing sills and the manner of connecting studding to the sills. Fig. 2 shows a corner detail. Fig. 3 shows a cross-tie and brace detail. Fig. 4 shows in section the fastening of a stud to the side sill. Fig. 5 shows a connecting-fillet. Fig. 6 shows in detail the fastening of the cross-tie to the middle sills. Fig.
-7 is a sectional elevation of a portion of a car,
the roof, the rootframe, the floor-sills, and fcontinuous draw-bar.
This canti-ame, as shown, is made entirely A of metal, of shapes easily rolled, and, in fact,
commonly found on sale.
A represents the side sill made of two channel-bars c c', placed with their concave faces toward eachother. One or both of these may, if preferred, bemade of an I-beam; but for readiness in turning corners, as appears hereinafter, the channel-bars are preferable.
B2 represents a corner and shows the manner of turning an angle with the side sill without breaking o-r cutting the beam. To make this corner, I cut a gore from the fiange or flanges of the channel or angle bars a, bend the bottom of the channel to the required angle, and strengthen with a fillet b. By using angles formed in this way the entire outside sill,including cross-sills at the ends and both side sills, may be made continuous of the two members d af, or the outer member may be made continuous and the inner member placed only along the side sill. I prefer the latter construction, because I thus employ the cavity in the end or cross-sills within which to secure the ends of intermediate sills.
C Care studs of I or channel iron fastened to the side sills by bolts and a fillet D. The iillet D is made of peculiar form to fill the channels of both the sill and the stud, and for that purpose is made in the form of a cross, of which one arm is sunk slightly within the other, as though mortised into it. The upper side of the channel-bara has a gain cut in it, within which is received the part of the upright lying behind the outer face of the horizontal arm d. The lower side of the channehbar c is not provided with a gain and the end of the upright rests on the side of the channelbar. (Jn the obverse side of the arm d is a step d2, upon which rests the lower end of the stud C. It will be seen that when the joint is completed, as shown in Fig. i, each part has a bearing directly against another part, and the bolts holding the parts together are relieved from all shearing strain.
E E (the sills adjacent to the side sills) are compound channel-bars formed by two angle or Z bars together, the channel or concave side being placed downward. At points where the cross-ties G, hereinafter described, cross them there is bolted to each bar a support or standard E E', serving as a compression mem- IOC ' ing with the tie-plate G and the sills E E F F `ber to act as a support resting on the crossbrace H.
F F represent the middle sills. These are also composite beams made of angle-iron, channel-iron,or bars rolledinto Z shape, arranged to form two flanged channel-beams, with the flanges of one opposite to the flanges on the assembled compound beam, are rectangular in form, with a middle flange on either side eX- tending from end to end.
G is a cross-tie plate passing between the members of the upper half of the beam E and those on the lower half, the flanges ff coming above the tie-plate and the fiangesf coming below the tie-plate. Y
It is not necessary that all of the sills E E F F be made of metal, as any or all of them or the parts of the compound sills may be constructed of wood.
His a brace-plate bolted to the side sills and passing und er the inner sills and formatruss across the car-bottom, serving to cause each one of the sills to be sustained by all the others'and to distribute the load. I is a similar brace-plate passing from the side sills over the middle sills.
F F (the two middle sills) have their under halves e e, Fig. l, extended under and beyond the end cross-sill J, and between themV is attached a draw-head K. The two middle sills thus form a draw-bar continuous from end to end of the car, and so connectedto the framework as to form a part of the car itself. The
dead-woods or bumpers may be bolted to the upper sides of the flanges e e, and any blow received against the bumpers will be resisted by that part of the frame best calculated to withstand it. The upper halves of the sills E E F F are received within the channel of the end cross-sill` and are bolted to it either with or without an included fillet.
Instead of making the corners of' this car rectangular, I make the endbayed, preferably making thecar a long Octagon, havingtwo long sides, two ends, each about four feet long, and four corner-faces, each about or a little less than three feet. With this construction the meeting faces or ends of the cars extend only two feet (more or less) from the coupling-pin to the part where they begin to widen out, and the liability of accident to the train-men in coupling cars is greatly reduced and the car is strengthened.- On the corner-face of each car I place the rounds of a' ladder L, which the train-man may grasp and by which he can sustain himself if threatened from any cause.
cc c are tie-rods passing from the side-sills to the roof-plate and forming with the studs, sills, and roof-plate a number of truss structures along the side walls of the car, there beingone such truss over each truck.
Hanging tie-rods h h and a truss-rod h support the inner ends of the side trusses just described.
Upon the side walls rests a root` of corrugated iron or other suitable material.
In the construction of this car of iron beams in the way described-each joint can be easily packed with felt or paper or other non-conducting material, the parts being so firmly held together that Vsuch packing will not be destroyed by any slight motion of one part upon another. At the same time the interposed packing will effectually prevent any creaking, straining, or rattling noise.V It will be noticed that throughout the structure there is kept in view constantly the dispersal or scattering of forces, both of draft and of concussion. The dead-wood bolted to e e serves to receive and transmit to the middle sills, to t-heA cross-sill J, and through that and the bracing angle-sills J J. the force of a push or stroke. It also serves when the car is-pulled from the other end (to scatter the forceof draft in the samev way, and the bracingY or arched form of the ends of the licor-frame by dividing the force among a. number of resisting members decreasethe liability to injury from either draft or concussion strain. In passenger-cars ythe doors maybe placed'in the corners and the sidetrussing carriedthrough below the windows.
M represents the root` of corrugated metal or any other suitable material. The siding is also of corrugated metal or wood or other suitable material. Vhere wood siding is used, a wooden furring is bolted to the sills and the siding nailed to it.
The car-frame thus constructed of metal is light in proportion to the strength, and I am able to increase the capacity very much in proportion to the weight of the car, while at the same time the construction causes. the strains of draft or concussion to be met by a practically solid frame.
IOO
If desired, any or allof the-channels within the beams may be filled with Wood or any proper tilling material, and, if desired, in place of the side channel bar or bars-a a an I-beam having a single vertical web may be used.
