To all .whom t may concern:

the following is a full, clear, andexactde- `scription', such as-willenable others skilled in the art to4 which it appertains to make and use the' same, reference beingmad `tothe ac# companying drawings, forming part of this specification, in which--. V

Figure l4 isa side' elevational view, partly insection, of myimproved draft rigging; Fig. 2 is a top plan view, partly in horizontall sectionyshowingthe draft rigging applied to thel cheek plates of a railway car; and Fig. 3 is a horizontal sectional viewtaken on theline 3-3 of Fig. 1.

This invention relates to new and useful.

improvements in .draft riggings for railway cars. v

In the preferred form of inv invention, a

yoke, which embraces or partially embraces springs constituting. theshock-absorbing inediuin of the draft rigging, yis built up of sections pivotally connected together, one ofv said yoke sections being secured-tothe drawbar. This construction allows a portion of 3c, the yoke to swing horizontally on.a pivot,

and the said yoke is thereby relieved ofthe abnormal stresses to which it is subjected when the car is going around acurve.

My improved .yoke is. particularly adapted for use in connection with a tandem spring'` draft rigging, but I'wish it to 'be under-` stood that the use of my invention isnot limited to this or any other particular form vof'draft ri ging. 3,

The draft rigging herein shogvvnis of the ordinary tandem type, and is composed of `two springs 1, interposed between follower plates 2 and 3. The follower plates normally engage lugs on cheek plates 4,',as shown in mally engagesl the frontv 'follower plate 2.

Fig. 2. 5 indicates the drawbzft'whichnor- Yoke members @are secured to the drawbar by means, of rivets 7, or other suitable fastening-devices, the forward ends of 'said members being provided with lips 8 which are arranged between lugs 5a and 5b formed integral with the drawbar. Thus themeinbers 6 may be said to constitute rearward extensions of the drawbar. The members 6 constitute the front section of va yoke and absoi'" have curvedr'rear endswhich engage correspondinglyshaped shoulders 9 on. the reary v -yoke section. The rear yoke sectionprefen ably'embracesfthe rear draft spring and4 is provided. withan enlarged front portion l() havin curved faces 11.0%l which normally engage t eintermediate follower plates 2 and 3, respectively, The rearvv end 'of each nicmber 6 isiprovided with a circular boss l1 'which extends into a circular socket in the rear yoke-section; A bolt or rivet l2, ar-

yoke section. The circular bosses ll forml a `'ranged 'within a 'piece of' pipe 13,' passes through the center of the bosses lll through the enlarged portion 10 of the rear PVOm1 Connection. between the front and"` f rear yoke sections and prevent the rivet 12 and pipe 13 from receiving a shearingv strain during butling and pulling shocks..

Thesprings 1 are compressed between `the the' drawbar and yoke moveV the ollower plates 2 rearwardly and the follower plates 3 are prevented from lmoving by lugs'on the cheek. plates ll. The pulling shocks on the follower plates when the car receives a builtu ing or pulling shock. During buiin shocks drawbarcause the yoke to move the follower I plates 3 forward and during this movement the follower plates 2 are held'stationary by lugs on the cheek plates 4.

Having thus described my invention, what I claim as new and vdesire to secure by Let ters Patent is: lain4 a `draft rigging, @shock-absorbing device, a drawbar, and a yoke, said yoke be ling composed of members that are pivotally connected together intermediate the ends of Vsaid. shock-absorbing device. i i 2. Ina draft rigging, a, shock-absorbingw means comprising a plurality of elements,

and an actuating means coperating with said shocloabsorbing means, said actuating.iv means comprising members that are pivotjally connected together at a point between the elements of the shoclcabsorbing means-,1,

-3. [jn a draft rigging, followeraa shock#- iig matineeinterposed between said follower, 'Dite member, and a drawbar for `actuating said followers, saiddrawbar being provided withrearward extensions that are pivoted .to said yoke member at a pointl between the followers.

t. In a draft ri O'ino" end followers 'inf ico? eiid and intermediate followers, a yoke member, and a drawbar having rearward extensions that are pivotally connected to said yoke member at a point between two of the intermediate followers.

5. In a draft rigging, a drawbar, a yoke composed of sections pivotally connected together, one of said yoke. sections heilig secnred to the drawbar, and a shock-absorbing element actnated by said yoke and drawbar.

6. in a draft rigging, a drawbai', a yoke composed of a lplurality of sections, one of which is securedto the drawbar, and a shock-absorbing element embraced by said yoke.

7. In a draft rigging, a plurality of shockaiisorbing devices, a yoke embracing' said devices and comprising a plurality of sections thatvare pivotally connected together intermediate said devices, and a drawbar connected to one of said yoke sections.

.8. A tandem draft rigging comprising end followers and intermediate followers, shock-absorbing devices arranged 'between' said follo\vers,members cooperating with said end followers, and a pivotal connection between said members located between the intermediate followers.

9. In a draft rigging, a drawbar, end followers, intermediate followers, a shock-absorbing device interposed between each end and intermediate follower', a yoke comprising two sections, one of which entirely surrounds one of the end and intermediate fol` lowers, theother yoke section beingin the form of bars rigidly connected to the drawbar and pivoted to the first-mentioned yoke section.

10. i yoke for draft rigging, comprising sections pivotally connected together.

11. A yoke for tandem draft riggings,l comprising a rear section having an integral portion that is adapted 'to lie between the intermediate followers of the rigging, and

integral portion.

12. A yoke for tandem draft riggings,

` comprising a rear section having-an integral g portionthat is adapted to lie between the intermediate followers of the rigging, and a front section having integral projections that fit in sockets in the integral portion of said reail section so as to pivotally connect said sections together.

13. AA tandem draft rigging', comprising end followers and intermediate followers, a pair of shock-absorbing devices coperating with said followers, a yoke surrounding the rear shock-absorbing device and the followers that cooperate therewith, and a drawbar coperating with the end follower of the front shock-absorbing device and having rearward extensions thatare pivotally connected to said yoke.

14. A- tandem draft rigging, comprising end followers and intermediate followers, a pair of shock-absorbing devices copcrating with said followers, a yoke surrounding the rear shock-absorbing device and the followers that cooperate therewith, and a. drawbar cooperating with the end follower' of the front shock-absorbing deviceand having rearward extensions that are pivotally connected to said yoke, said yoke having lcurved surfaces that bear against the intermediate followers.

15. A yoke for draft rigging, comprising two sections, one of which is in the form of a continuous loop, the other section being in the form of bars, each of said bars being provided with an integral projection which interlocks with thev other section.

16. ln a draft rigging, a drawbar, a yoke connected thereto and consisting' of members that are pivotally connected together, and a shock-absorbing device interposed between the drawbar and the' pivotal connection of said' yoke members.

17. In a tandem draft rigging, a drawbarl otal connection and coperating with the a front section pivotally connected to said yoke member. In testimony whereof I hereiinto afiix my signature in the presence of two witnesses, this twenty fourth day of October, 1908.
