To all whom t may concern:

Be it known that I, WILLIAM E. WINE, a citizen of the United States, and a resident of Toledo, county of Lucas, and State of Ohio, have made and invented certain new and useful Improvements in Underframes for Railway-Cars, of which the followingis a specification.

My invention relates improvements in underframes for railway cars, and more particularly to a reinforcing and strengthenlng means that may be applied to the wooden center sills of freight cars to materially strengthen the same.

'llhe tendency toward longer and heavier trains naturally increases the severe bufling and pulling stresses to which the cars are subjected, which often results in damaged cars, and it hasI become a common practice to remove the wooden center sills to which the draft rigging is secured, and substitute therefor steel center sills or steel underframes at comparatively great expense.

The object of my invention is to provide a novel construction adapted for use in the repair of wooden cars which have become damaged by bung shocks or severe strains, or to apply directly to wooden cars which are in good condition but which would in time become ldamaged bythe strain which they are now subjected to.

Another object of my invention is to provide a reinforcing means that may be readily applied and which will only necessitate the removal of the old wooden end sill,jack ing the car body 0H of the holsters and needle beams and inserting the reinforcing means longitudinally of the center sills.

Still another object of my invention is to provide a reinforcing means that may be inserted .between the wooden center sills and will produce a lower center of gravity of the section, which is greatly desired for two reasons, first, it brings the neutral axis of the beam or member in line with the coupler horn for buiiing, and second it reduces the eccentricity of the center line of the draft gear from the neutral axis.

Still another object of my inventlon is to provide a reinforcing means that is made up entirely of standard commercial bars .of steel or sections, and requires no special dies or machinery for its manufacture.

to new and useful Still another object of my invention is toy so join the sections that the rivets are located approximately of the neutral axis ofv the member, thus'not having to punch the rivet holes through that part of the beam which is subjected to the tensile or compression strain.

Still other objects of my invention are to provide a reinforcing means which is light 1n weight and providing a maximum of strength fora minimum amount of material used; to provide a reinforcing means that will be neat in appearance and readily assembled and cheap to manufacture.

With these and other objects in view, my invention consists in certain new and novel constructions and combination of parts which will be hereinafter more fully described and pointed out in the claims. l

ln the accompanying drawings: Figure l is a fragmentary top plan view of my improved reinforcing means; Fig. 2 is a side elevation of the same; Fig. 3 is an end view; Fig. 4 is a sectional view taken on lines i-4t of Fig. l; Fig. 5 is a fragmentary top plan view of a slightly modified form; Fig. 6 is a side elevation of the same; Fig. 7 is an end View of the same, and Fig. 8 is a sectional view taken on lines 8 8 of Fig. 5.

Referring now to the drawings, it will be seen that the reinforcing means is made up of four angle sections; two of the angles Il and 2 formed with relatively long vertical legs or webs 3 and 4 and upper portions 0r flanges 5 and 6 which extend inwardly. Securely riveted to these web portions are the other angle members 7 and 8, the webs of these angles 9 and 10 extending completely under the wooden center sills 9 and 10. This reinforcing member is adapted to extend the entire length of the wooden center sills, and although only one end is shown, it will be understood that the illustration and description of one end portion is a complete description and illustration of the remaining end portion.

By providing a wide bottom web which extends completely across the bottom of the wooden center sills, two advantages are obtained, in that the web reinforces the old wooden sills laterall and also renders the application of the evice to the car much more simple, as the web will be provided riveted to the bottom webs 8 and 9, and -the with holes that register with the.I bolts that already extend vertically through the wooden sills, thus doing'away with the necessity of boring separate bolt holes through the said sills. Furthermore the distribution of the metal in the bottom webs lowers the center of gravity of the center sills,

which as heretofore mentioned is greatly desired.

The draft arms 11 and 12 are securely low center of gravity of the section by the use of the wide bottom webs brings the neutral axis of the beammember nearerin line with the coupler horn for buiiing. Secured to the ends of the angle members 1 and 2 are the reinforcing plates 13 and. 14, which contact with'the tie plate 15. Also at different oints throu hout the length of the reini, ers are located separators 16,

orcmg mem which are shown in dotted lines in Fig. 1,

which separators may be of any desired shape or length and extend from the vertical flange of the bottom member on one s1de to the vertical iange on the other s1de, and

which separator may be solid or of stamped metal, the object being to additionally reinforce the angles and guard against the transverse strains of the center sills. These separators 16 are securely riveted to the.

members mentioned, and as many rivets being used as desired. The separators that are used over the bolster are of course provided with a passageway for the admission of the king 1n.

Re errin now to. the modified form shown'in Figs. 5 to 8 inclusive, it will be seen that in this instance slightly diii'erently shaped angular members are used, as the members 19 and 20 when assembled in'this` instance form a structure box-like in cross section. Also securely riveted to these members 19 and 20 are the sections 21 and 22 which extend transversely across the center sills, but extend longitudinally of the ycenter sills for only a portion of their length. The end plates 23 and 24pm this instance .are secured to the inner sides of the members 19 and 20 in contradistinction to the outer side as shown in Fig. 1. By providing angles of suicient weight it is possible to t reconstruct the wooden underframe of old cars and at the same t1me make them nearly as strong and substantial as an all-steel underframe one, and at the same time the expense far less than an all-steel underframe.

From the foregoing it will be seen that the structure er Ise may be quickly and readily assemb ed, and that-it may also be applied to the wooden center sills at a relatively small labor expense. 'Furthermore the bottom webs are bolted tothe center sills, it being possible to use the old bolts now in use, thus doing away with the expense of drilling additional holes throughout the length of the center sillgfffurthermore, the lower center of gravity is obtained and the vposition of the -rivets is such that the strength of the angles is not materially lessened.

Variations may be made without departing from the spirit of the invention.

- Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A reinforcement for wooden underframe railway cars, comprising angle members adapted when placed in position to extend along the inner adjacent sides of the sills of the underframe, a second set of angle members the flan es of which are secured to the webs of the rst mentioned angle members, and the webs of the second set of angle members extending outwardly, and means secured to the webs of said second set of 86 angle members for the reception of a draft.
