To all when it may concern;

Be known-that I, CHARLES S. SIIALLF.N' BnneER, aeiti'zen'of the United States,-residing at StgLLouis, Missouri, have invented a certain and useful Improvement in Draft-Riggings for Railway-Cars, of which" the following is'a full, clear, andexactdescri )tion, such as will enable others skille in t e 'a'rtto which itappertains to make an use; the samarelference being had to the accompanying'flrawings; forming part of this 'lhisinveritidi'i re .es'to draft l'iggings, and particularly to e-drawbar yokes used in tandem draft riggings.v

One object-of my invention is to provide a yoke that is composed of a number of independent sections which are detachablyconneoted together so that a new section can be substituted for a broken section and thus overcome the necessity ofdiscarding the en. tire yoke in case any portion thereof breaks. And another object of my invention is to provide a cast metal yoke for tandem draft riggings which is stronger than the yokes that have heretofore been in use.

Briefly described, my invention consists in a yoke composed of a number .of separate sections or members arranged in'longitudinal alinement with each other and detachconneeted together. y the'preferred form of .my invention, as hereinshown, the sections of the yoke are approximately .Ushaped, and each section has a portion that interlocks with an adjacent section so as'to enable the sections to be takeh apart and assembled easily. The first section of the yoke is connected to'the drawbar and the other section or sections are arranged one behind the other in longitudinal .alinement with the first section, the cross webs of said sections cooperating with the followers of the draft rigging and the legs of said sections embracing said followers and the shock-absorbing elements of the rign A yoke ofthe construction above described greatly reduces the cost of maintaining draft riggin 's owing to the fact that the entire yoke does not have to be dlscarded -in case any portion thereof breaks.

Fi urel; of the drawings is a side eleva not View of adraft rigging constructed in iccomancej'withmy invention; Fig, 2 1s a ileriri pe ly nhofiz n l vs c .of said draft rigging; Fig. 3 is a perspective view of the yoke; and Fig. 4 is a perspective view of a yoke of slightly different constructionfrom the one shown in Fig. 3.

Referring to the drawingswhich illustrate a draft rigging-that comprises two setsof omen springs orshock-absorbing elements, 1 designates the springs or shock-absorbing elements.-each of which is.arranged between a front follower 2 and a rear follower 3 which cooperate with lugs or stops-on-cheek plates 4, as shown clearly in Fig. 2. v

My improved yoke is composed of'a plurali t y of separate sections or members which are substantially U-shaped'and arranged in longitudinal alinement with'each other, the front section A being connected to the drawbar 5 by fastening-devices'6, and the rear section B being detachably connected to-the front section A. The front section is preferably provided with lips7 which interlock with lugs on the'drawbar so as to reduce the shcaring'strains'ou the fastening" dex'ices 6, and the rear section B is provided with lugs, or extensions 9 that project into slots or pockets 8 in the rear end of the section A. A fastening device 10 is preferably passed through the rear section B and the portion of section A which said rear section embraces so as to hold said sections in longitudinal alinement with each other and also into the notches 8 in the front section A, re-' ceire some of the shocks and strains to which the cross web of the section A is subjected and thus reduce the liability of said cross web being sheared off or broken and the fastening device 10 that passes through'the sections reduces the shearing st-rains on the extensions 9. v

In case one section of the yoke breaks it is not necessary to discard the-entire yoke for anew section can be'substituted easily for thebroken section and thus repair the yoke at approximately one-half the cost of a onepiece metal yokeof the kindheretofore n use' i If desired,the cross webs of the sections A and B can be provided with curved faces 11 as shown 'in Fig. 2 so as to permitthe draw-bar to swingor rock while the car is going around curves.

In Fig. 4- I have illustrated a slightly modified form of my invention wherein the rear section B of the yoke is provided with lips or projections 9 having concaved inner edges which conform to the concaved bottom walls of the slots 8 into which said lips project, the legs of said rear section B also being'provided with concaved faces 12 that engage convexed surfaces on the front section A, as shown clearly in Fig. 4 With such a construction it is not necessary to connect the sections of the yoke together by means of fastening devices as the shocks to which the yoke is subjected when in use do not tend to make the sections rotate relativelyto each other. In assembling the parts of the yoke shown in Fig. i the lips or extensions 9 011 the rear section B are partially inserted in the slots 8 and one section of the yoke is prising two substantially U-shaped members arranged in longitudinal alinement with each other and with their legs projecting in the same direction, the cross web of the front member being provided with slots whose bottoms are convexed, and lugs on the rear member that project into said slots,.the lower ends of said lugs being concaved so-that they will'conform to the shape of the bottoms of said slots.

In testimony whereof I hereunto 'aflix mysignature in the presence of two'witnesses,

this twenty-fourth day ofvOctober 1908.

CHARLES S. SHALLENBERGER.
