To all whom 'it may concern:

Be it known that l, RICHARD D. GAL- LAGi-IER, J r., a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Car Construction; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates particularly to the construction of passenger cars and to the underframing, buifing and draft mechanism of the same.

The objects of the invention are to improve the construction and arrangement of the movable and resilient elements of the bufling mechanism, as well as the fixed pressure resisting elements for transmitting the strains to the body of the car.

The invent-ion consists incertain novel details of construction and combinations and arrangements of parts, all as will now be described and pointed out particularly in the appended claims.

Referring to the accompanying drawings-Figure 1 is a plan view of a portion of a car frame and bufiing mechanism at one end of a car lying on one side of the longitudinal center, the flooring and super-structure being removed; Fig. 2 is a front elevation of the parts shown in Fig. 1 with the movable parts of the bufng and draft mechanism removed. Fig. 3 is a vertical section on a line corresponding to the line 3-3, Fig. 1, but illustrating parts on the opposite side of the car from those shown in Figs. 1 and 2. Figs. 4 and 4A are sectional views in a central vertical plane, said views illustrating continuations of the same parts. Fig. 5 is a vertical section on the line 5-5, Fig. 1, with parts broken away. Fig. 6 is a transverse section on the line 6-6 Fig. 4A. Fig. 7 is a section on the line 7 7, Fig. 4A. Fig. 8 is a detail side elevation of a part of the draft gear centering mechanism. Fig. 9 is a top plan view of the centering mechanism, including the stop castings or spring pocket. Fig. 10 is a transverse section through the draft springs and parts immediately associated therewith.

Similar letters of reference indicate like parts in all the views.

The car frame illustrated in the accompanying drawings embodies main longitudinal sills A of channel-iron section and preferably extending from end to end of the car. In addition to the longitudinal sills A, supplemental longitudinal sills B are provided which, on the inner side of or between the end sills C of the body, are adapted to lie flat against the longitudinal sills A, as best seen in Fig. 7, the two thereby forming, in effect, longitudinal sills of I beam section.

The supplemental sills B are bent down to pass beneath the end sills C of the car, as best seen in Fig. 4A and they extend to the end of the car to form the draft timbers. By thus bending or offsetting the supplemental sills B they are, at a point within or between the end sills of the car elevated to a suiiicient height to afford the necessary space for electric motors, etc., without weakening the frame construction and without tendency to throw the parts outof aline-- ment under severe bufiing or draft strain.

To reinforce the supplemental sills B, they may be provided with reinforcing angle iron edge pieces B at the lower edge and where they depart from the plane of the longitudinal sills A they may be conveniently riveted to suitable bottom strengthening plates B2 (Fig. 4A).

The end sill C is built up across the ends of the sills A and is preferably formed of angle irons o riveted together and suitably connected to the ends of the sills A. Said end sill C is further braced and strengthcned by an inverted truss-iron D secured thereto at its ends and passing down beneath the sill B and beneath the spacers or queen posts D through which bolts cl pass upwardly to connect the truss and center sill at each side of the center. By this construction the supplemental sills B are held firmly against the bottom of the end sill C or the end sill is held firmly down on the supplemental sills B and the whole structure is united rigidly together. Forward of the end sill C longitudinal platform sills E are introduced above the supplemental sills B as best seen in Fig. 8, the said platform sills being of channel iron section and arranged reversely with respect to the supplemental i by a filling sills B whereby the overlapping flanges may be readily riveted or otherwise permanently connected together so as to form deep girders of great strength well adapted to resist lateral deflection and to transmit the bufling and draft strains to the body of the car. The buffer beam which is also built up of angle irons and plates, is rigidly mounted on the ends of the supplemental sills and longitudinal platform sills, thus, as shown particularly in Fig. 5 it will be seen that a curved channel iron F forms the front of the body of the buffer beam, and angle irons F connected by a plate F 2 form the rear wall of the buffer beam. The plate F2 it is obvious need not be continuous from end to end of the buffer beam, but may be interrupted between the central longitudinal platform beams, but it is connected to said platform sills and to the supplemental sills B by brackets f. Between the angle iron F and channel F suitable bracing plates F3 may be introduced, as shown in Figs. l and 5. To the front of the channel iron F at the center of the buffer beam there is secured the butler beam extension G preferably madeof malleable iron. Conveniently the extreme ends of the supplemental sills B extend under and support the buffer beam extension, The general contour of the forward face of the buffer beam extension is curved and at the ends of said extension, the buffer beam is strengthened and rounded piece Gr which may be of wood with a metal face g, the general curvature of said face conforming to the general curvature ofA the buffer beam extension for a purpose which will presently appear.

The lower angle iron F of the buffer beam is preferably arranged in the form of a downwardly bowed truss iron, as best seen in Fig. 2 of the drawings, so as to form .with the bottom plate f2 a connection which passes beneath the supplemental sills B and serves to impart additional strength to the buffer Abeam structure.

To the outer sides of the forward ends of the supplemental sills B there are attached hanger straps H for the carry-iron H of the draft mechanism, as will be readily understood from Figs. 2 and 4. To provide a smooth bearing for preventing the draft mechanism from moving upwardly and at the same time to permit it to swing laterally on the carry-iron H, a wear plate I is mounted on the lower corners of the supplemental sills B and extends from one of the hanger straps H to the other, thus confining the draw bar to its channel between the irons H and I.

The draw-bar indicated by the letter K is, at its inner end, connected directly or indirectly with a yoke or strap K which is adapted t0 pass around the usual followers 7c having between them the draft springs /v (Fig. 9). The followers c are confined loosely within stop irons or spring pocket L (Fig. 4A) depending from the under edges of the supplemental sill B and securely bolted to the strengthening flanges of said sills. For restoring the draft bar to its central position, the strap K at its forward end is provided with a block K2 adapted to bear against the forward follower 7c and at its rear end it is provided with a cup or spring box K3 adapted-to confine within it a supplemental spring K4L which rests against the rear follower le, the said spring K4 being of less initial capacity than the draft springs, and there being only a slight play allowed between the spring box K3 and-the rear follower c. lVth this arrangement any draft strain or radial movement of the draw bar will initially compress the spring KL and if the draw bar is released while the spring is under compression it will be returned to its central position. The draft-springs it" cannot ordinarily be utilized for this purpose, because of the difiiculty in arranging the followers within the yokes sothat no play can occur. Thus, if the spring pocket is too long, the device would be inoperative to bring the draw bar back to the center of the car, but with the present arrangement the parts are held tightly together and the spring K4 exerts a constant tendency to return the parts to their central position, even though the follower and draft springs should not fill1the space between the stop faces of the spring pocket.

By reference to Fig. 2 it will be seen that the buffer beam extension and buffer beam are provided with bearings M and M for the center and side stems m and m of the buffer. Said stems are pivotally connected with the buffer at their forward ends and at their inner ends cooperate with the buffer,

springs and parts to be now described. The center stem m at its inner end passes through a bracket O held by a bridge piece O between the longitudinal platform sills and is prevented from outward movement by a key m2. This limits the outward movement of the buer at the center but without interfering with the capacity of said buffer to move angularly from, say the position indicated in full lines in Fig. l to the position indica-ted in dotted lines in said figure.

The side stems m at their inner ends are supported in brackets O2 and carry spring followers P and P', the latter being mount' ed on the bracket O2 and forming bearings for the inner end of the stem. Between the followers P and P two springs are confined, one lettered p being a relatively light spring with a long range of elasticity and the other 7? being a relatively heavy spring. Said springs may be conveniently separated by a spacer 792 and in operation it is intended that initial inward movements of the buffer shall be resisted practically exclusively by the lighter springs 79, the range of movement being such that the buffer may be moved 1nvvardly until coupling is effected without undue resistance but from the coupling position to the final seating of the parts the resistance shall be greatly augmented owing to the fact that the movement of the outer springs is then entirely absorbed and the heavier springs are brought into action. To prevent deformation or setting of the lighter springs the follower P and spacer P2 are adapted to contact when the initial movement resisted by said springs is ending and from thenceforth inward movement is resisted entirely by the heavier springs. During the initial inward movement of the buffer the center stem m (Fig. 4) is not designed to exert any outward pressure, owing to the fact that its shoulder is normally spaced away from the cooperating shoulder q of its forward follower .Q and consequently the center stem spring Q located between the follower Q and the bracket O is not put under increasing tension until the shoulders g and g engage and move the follower Q inwardly. Forward movement of the follower Q is limited by the buer beam, whereby the side springs p will, in effect, give the final outward movement to the buffer and will alone resist initial inward movement of the same.

The arrangement of the springs described permits of a very wide range of angular movement of the buffer as, for instance, when rounding short curves and, in order to take care of the cooperating buffers under extreme conditions, the parts are so proportioned and the outer face of the buer beam is so shaped at the ends that the coopera-ting buer will, when occupying a position at one side of the center, bear against the rounding face of the buer beam. This extreme condition is illustrated in Fig. 1 where the cooperating buffer or buffer on the adjacent car is indicated by the dotted lines S and it will be noted that in the extreme position indicated, one car being on a tangent and the other on a short curve, the buffers are parallel with each other, but are displaced transversely and each will partly rest against its cooperc ting buffer and partly against the cooperating filling piece of the buffer beam. The arrangement insures a good platform or bridge between cars at all times and further insures a proper bufhng action, even under extreme conditions.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is
