'WILLIAM H. MINR, 0F CHICAGO, ILLNOIS Application led December 30, 1910. Serial No. 606,170.
To all 'whom it may concern Be it known that I, WILLIAM H. MiNER, acitizen of the-United States, residing in Chicago, in the county of Cook and State of Illinois. have invented a new and useful Improvement in DraweBar and Yoke Connections for Railway Draft-Rigging, of which the following is a specification.
My invention relates to improvements in car coupler draw-bar and yoke connections.
Heretofore, great difficulty has been eX- perienccd in draw-bar and yoke connections generally in use fromshearing-of the tivo ,rivets which extend through the draw-bar 15 and yoke under the heavy strains, shocksvv and blows to which railway draft rigging is sulnccted.
The object of my invention is to provide a draw-bar and yoke connection which will 'be very much stronger than the two rivets heretofore employed, and which at the saine tiinewill enable the yoke and. draw-bar to be connected by a pair of rivets when occasion may require for repairs or other purposes.
DMy invention consists in the means einployed to practically accomplish this object or result as herein shown and described and more particularly specied in the claims.
- In the accompanying drawing forming a part of this specification, Figure l is a plan View of a draw-bar and yoke 'connection enibcdying one form of my invention. Fig. 2 is a side elevation, partly iii central, vertical section on line 2 2 of Fig. 1. Fig. 3 is a detail plan view showing a preferred means for securing the key in place. Fig. l1 is a detail section online 4 4 of-Fig. 3. Fig.
5 is a detail section on line 5 5 of Fig. 4. Fig. 6 is a detail plan View, showing the filler block which is interposed in the key slot of the draw-bar When'it is desired to connect the same by' rivets. Fig. 7 is a horizontalsection showing the preferred form of the key slot injthe draw-bar and of the filler' block recess. Fig. 8 isadetail section o-n line 8 8 of Fig. 7. F 9 is a detail elevation of the filler block 4employed inY the construction shown in Figs. 7 and S and' Fig. 10 is a detail plan view of saine.

ward -ends of the two limbs of the draft yoke, the draw-bar preferably havingA transverse grooves 5 in its upper and lower faces to receive the gibs 4 of the draft yoke and thus affording further abutment shoulders 6 on the draw-bar for engagement with the draft yoke gibs.
The draw-bar is provided with an upright longitudinal slot 7 having semi-circular end walls 8, the transverse width of the slot 7 being the diameter ofthe customary rivets employed in Ithe regular Master Car Builders construction, and the length of the slot 7 correspondingto the spacing of the rivet lioles in the customary or standard Master Car Builders construction. The draft vokc 2 in like manner is furnished at its front ends with an upright, longitudinal slot 9 i having semi-circular front and rear Walls 10, 11 and conforming in shapeand size to 'the slot 7 in the draw-bar.
12 isa connecting key having a head 13 at its upper end and senii-circular curved front and rear walls 14, 1'5 adapted to snugly t the upright slots in the draw-bar and yoke. A 'Washer 1 6 is provided at the lower end of the key and a fastener 17, which is iiiseited through an opening in the lowereiid of the key and which serves to hold. the key in place. Filler blocks 18, having convexly curved front and rear Walls 19, 20 are adapted to fit in the slot of the draw-bar when the key connection is not employed, and rivets 21 are employed with a-rivet-liole yoke of the standard Master Car Builders present construction for connecting the draw-bar and draft yoke.
In the construction shown in Figs. 3, 4 and 5, a wedge 22 is employed as the fastener for securing the key 12 in position, the key in this construction having a slot 23 with an inclined face 21 for engagement With the'inclined face 25 of the wedge. The Wedge is secured in position by a locking device 26, the key having a series of holes 27 to receive the locking device 26.
In Figs. 7, 8, 9 and .10, which illustrate the preferred construction of filler block, the
iller block'is provided. with lugs 28 on its the upright side walls of the key slot 7, the
lugs 2 8 serving to hold the filler block in placevand giving the same anchorage in the draw-bar independent of the rivets. The filler block thus serves asan additional connection between the draw-bar and yoke in resisting bufng and pulling strains.
1. A draw-bar and yoke connection coinprising, in combination: a draw-bar provided with an upright slot therethrough of a Width equal to the diameter of a standard rivet and having semi-circular curved front and rear Walls, the centers of curvatureo said Jfront and rear Walls of the draw-bar slot being spaced apart a distance equal to the distance 'between centers of a pair of standardly spaced connecting rivets; a draft yoke, the arms of which are provided With perforations in alinelnent With the slot of the draw bar; means for connecting said draw-bar and draft yoke, said means, including a pair of connecting rivets extending through the draw-bar and yoke and a filler block; .and coperating means on the draw-bar and ller Block for anchoring the latter in position, substantially as specified. I
2. The combination with a draw-bar and draft yoke both provided With upright, longitudinally extending slots having semi-circular front and rear Walls spaced apart a distance corresponding to the distance be" concavely curvedl front and rear .Walls of said filler block, said filler block having anchoring lugs on its upriglf sides and the draw-bar having recesses to receive said anchoring lugs, substantially as specified.
