CAR CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 432,273, dated July 15, 1890. Application filed February 25, 1890. Serial No. 341,684- (No model.)

strong and durable car at a minimum of cost and of the lightest weight consistent with servieeability.

lhe leading feature of my improvement is a construction which will permit of the frame members being secured together without the necessity of welding, bolting, riveting, or of weakening them by gaining, mortising, slotting, or puncturing With bolt or rivet holes. Incidental to this main feature of my invention are certain novel structural features adapted to the carrying out of the principal invention in an economical and etficient manner.

In carrying out my invention I employ, preferably, for the principal parts of the framework of the car metal beams having the maximum strength with minimum weight and size, and I find well adapted to these ends the channel-beams of commerce, which are adapted for use in a car of my improved construction for sills and top plates without change of form, and I can buy in the markets beams of the precise length required and use them exactly as they come from the dealer. reasons channel-beams are best adapted for the sills and top plates; but other forms of beams may befound entirely suitable, such forms including, among others, I and T beams and angle-irons. Keeping in mind the desirability of securing great strength without unduly increasing the weight and bulk, me-

' tallic beams of the sort mentioned are preferably employed; but my invention is capable of embodiment in a car wherein these beams are of wood, and in the particular construction herein described the metallic beams are in some cases lined or filled with wood to secure increased strength, and also to provide for securing to the frame the siding, roof, or sheathing. I take, by preference, as the substructure of the car side sills consisting of two metallic beams, channel or U beams be- For certain ing the best, and for the longitudinal beams or sills to support the floor of the car between vthe side sills I may employ for the central sills channel-beams turned back to back, and

for the intermediate sills the I-beam is well adapted. For the end sills I use, by preference, a channel-beam turned with its open side to receive the ends of the longitudinal beams or sills and secured thereto in any convenient manner. The standards or uprights, which form the frame-work for the vertical walls of the car, are also preferably composed of metal beams, channel or angle bars being Well adapted for the purpose, and these standards are secured with the side sills by having their lower ends projected below the bottom of said sills and passed through plates on the under side of said sills, the lower ends of the standards being apertured to receive keys or bolts, or threaded to receive nuts, whereby they are clamped, together with the plates, securely to the sills.

In the preferred form of construction the side sills will be composed of two parallel beams arranged side by side and a suitable distance apart to permit the lower ends of the standards to pass between them, and the plates through which the lower ends of said standards pass'will be fitted to receive the beams and apertured for the passage of the lower ends of the standards, as before stated. The top plates may consist of similar beams having caps fitted to embrace their upper edges and apertured for the passage of the upper ends of said standards, which are perforated for the passage of the key or bolt or threaded to receive nuts. In this way the sills, standards, and the plates are all firmly anchored together, and the frame may be f u rther strengthened by diagonal struts or a side elevation of a frame of a car containing some of my improvements. Fig. 2 is a trai'isverse sectional elevation thereof on the line 2 2 of Fig. 1. Fig. 3 is a broken plan 5 view of the side sills, the standard showing in transverse section. Fig. t is a side elevation of the same parts shown in Fig. 3. Fig. 5 is a detail in broken elevation of one of the side sills at the junction of a standard therewith,

IO and showing a peculiar form of securingplate forthe tie-rods and said standard. Fig.

6 is an end elevation of the parts shown in Fig. 4. Fig. 7 is an end elevation of the side sills and the bottom plate for securing the IS standard and tie-rods. Fig. 8 is a section showing composite channel-beams suitable for use as side sills. Fig. 0 is a perspective view of the lower end of a double standard,

as shown in section atthe left of Fig. 3. Fig.

10 is an inside view of the lower end of one of these standards adapted to receive a wooden lining, and showing provisions for securing thelining, the same parts being shown in transverse section at the right of Fig. 3.

Fig. 11 is a transverse section through the side sills (single in this instance) and through its securing-plate, a tie-rod and standard showing in broken elevation. Fig. 12 is a transverse section through a side sill, which in this instance is a U-beam, and showing also the lower end of the standard and the tie-rod secured with the sill by a cap. Fig. 13 is a perspective view of the lower end of an upright standard, the flanges whereof are cut away 3 5 and the web left intact and apertured forthe passage of a securing-wedge. Fig. 14 is a side elevation of a needle-beam. Figs. 15 to 18,

inclusive, are detail views of castings for securing the tie-rods to said needle-beam, and

Fi 18) is a broken perspective of the longitudinal and end sills.

In the drawings, the double side sills are indicated by A, and in the construction shown in Figs. 2, 3, 6, 7, and 8 are composed of channel-beams placed side by side and preferably with their flanges extending in horizontal planes and projecting toward the middle of the car. These beams need no special preparation whatever for use in the car, as they may be purchased in the markets of lengths adapted to the standard lengths of cars without cutting; but as it is cheaper to use composite beams than those integrally formed I have shown in Fig.8 types of this sort of beam 5 5 which are adapted to my purposes.

B indicates a bottom plate, which may extend along the entire length of the sill; butit may be constructed in separate sections and will have its uppersurface adapted to receive the particular form of sill selected. As shown particularly in Figs. 2 and 7 of the drawings, the upper surfaces of these plates have the projecting ribs 1), the central one separating the channel-beams and the outer ones confining them to prevent lateral movement, at the same time equalizing or distributing the strains on the parts of the side sills. These plates may be cast of the form shown in Fig. 1- or wrought to the form shown in Fig. 5.

Referring particularly to Fig. 2, C C represent the members of the central sills, which members are channel beams, whose lower flanges are seated upon a bottom plate 13 and whose upper flanges are adapted to support the floor, which may be anchored by means of the bolts 0, passed between the webs of the channel-beams and through an aperture in the plate 13 and secured by the nuts 0'. The intermediate sills I) may be I-beams.

E E represent the members of a standard whose lower ends have their flanges cut away and their webs perforated, as shown particularly in Figs. 9 and 10. and these beams may be placed together back to back and have their lower ends passed between the members of the side sills, as shown in Figs. 2 and 6. The apertured ends of these standards are projected through suitable openings in the bottom plate B, and will be secured by belts or keys F; or they may be threaded and secured by nuts. The plates are marked G G, Fig. 2, and they may be formed of channelbeams the same as the side sillsthat is, two of them being employed and separated to permit the passage of the upper ends of the standards, which may be formed in all respeets similar to their lower ends.

G represents a cap for the top plate, which may be formed in short sections; or a single continuous plate might be employed. As an additional means of strengthening the frame, I may employ the tie-rods H, (see Figs. 1, 2, t, and 5,) which may be extended diagonally between the side sills and plates, their ends projected between the members thereof, respeetively, and passed through apertures in the cap and bottom plates and secured by nuts or keys. The end sills are shown in Fig. 19 and are channel-beams whose flanges receive the ends of the longitudinal beams.

Instead of the double sills heretofore described, I may employ a single sill, as shown in Figs. 11 or 12, the former showing a single channel-beam supported by means of a standard having its web passed down on the outside of the channel-beam, and preferably welded thereto, and its extreme end passed through an aperture in a bottom plate, the other side of said plate being supported by a tie-rod H, while in Fig. 12 the U-beam is shown,the open side of the U turned downwardly. In Fig. 13 is shown the manner of forming the lower end of the standard when used as just described. In Fig. 11 the upper flange a of the channel-bar forms an acute angle with the web, and the standards have their flanges correspondii'lgly inclined, the result of which construction is that when the parts are secured together the inclined surfaces prevent lateral separation. In Fig. 10 the lower end of the standard has its web otfset at the junction of the sills or plate, and the web also has longitudinal slots (2 for the passage of screws or nails to secure the wooden filling E and also providing spaces for the passage of nails to secure the inside sheathing.

Referring now to Figs. 14 to 18, inclusive,

K represents a needle-beam, which may be an I-beam, and in order to stiffen this beam I employ the tie-rods L, which are passed beneath a block M, whose upper surface is fitted to embrace thelowerfianges of the I-beam and whose under su rfacc is grooved, as at m, to furnish seats for the tie-rods. The outer ends of these rods are passed through apertures in a clamp N, having grooves 12 in its front face to adapt it to embrace the end of the web and flange of the I-beam, and apertures 'n for the passage of the tie-rods, and which will be supported beneath the bottom of the car transversely to its sills, as shown in Fig. 1, or in any other convenient manner. I do not of course intend to limit my invention to the precise construction herein particularly illustrated and described, as the principle of my invention might be utilized where the structural adaptations were different. The resultant effect of my method of securing the frame members together is to obviate entirely any sheering effect, as the strains to which the joints are subjected are all tensile, and this is a matter of great importance in the construction of cars, which are subjected to continual and Violent oscillations when in use. This method of construction has other features of utility, such as the interchangeability of parts, and a consequent reduction of the cost of construction and the capability of replacing worn or broken parts For example, the standards are all interchangeable in cars of the same height. The cap and base plates may also be so made as to be interchangeable and adapted to cars of varying heights. These parts may also be used in the construction of various kinds of carssuch as freight and passenger carsand a car may have its construction changed, for example, to provide for doors or for closing openings in cars by the insertion or removal of one of the standardsreadily effected by the loosening of the wedges or nuts; and the height of a car may be changed by the removal of the standards and the substitution of others of greater or less length.
