DRAFT ANDBUFING APPARATUS.
Application filed May`11, 1906. Serial 110.316,40. I
To @ZZ whom/ it may concern.;
Be it known that I, SAMUEL l. BUSH, a resident of Columbus, inn the county of Franklin and State of Ohio,- liave invented certain new andy useful Improvements in Draft and Bufiing Apparatus; and l dohereby declare the following to be -a full, clear, and exact description of the invention, such as willeiiable others skilled in the art to which it appertains .to make and -use the4 same.I `My invention vcntion being .to'provide improvements of this characterJ comprising few and simple parts, which shall be easyand cheap to construct,.strong and. durable in use, universal in application andvery accessible.
i A further object is to provide an improved draft and buiiing'ap aratus whichwill be direct in action and o superior .to indirect wedge acting friction devices suchasheretofore known, and 'having a small reaction isy superior to strictly spring devices, at the same time having all the facilities formodifying or absorbing shocks between cars, as: possessed by either or both the Ordinar v spring and friction devices.
iiivention'consists in certain novel features of construction and' combinationsand arrangements of parts as will be more fully hereinafter described and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view in side elevation withdraftiron removed, illustrating my improvements. ig.
.2 is a view iii-cross section on the line mthereof. Fig. '3 is a viewV in crosssectionthroughtlie followers, and Figsl and 5 are views of afmodification. Figs.` 6 and 7 1 are;- views showing the.. positions 'of the parts .atv

Each ofthe followers 5, 6 is made witli The engaging facesl lateral trunnions 10 at their vlower ends and against each other takes place This is {ley 'sirable to cushionlight jars vand strains.
The draft irons 3 are provided with shoull i ders 12 to be struck by the followers 6 and limit their movement. i
' The operation of the device 'is as follows :'-v
The followers of one set move for the forward `action or pull and the other set take the buffing-strains.
I 0 5 e then stationary rear followers) will ycreate` IIO being released, the followers will be returned coupling, will move rearwardly toward theA i fulcrum of the latter on the bearings 14, and
, those that contact with each other.
the point of contact of the s ring with the follower 6 will move rearwar ly away from the fulcrum Aof the latter on the lugs 11. This arrangement allows the movements of the sprin(lr to be made greater than the movement oftthe coupling and results in a largely increased resistance to the action of the coupling toward the end of the. movement.
The contacting surfaces of the'followers, which may or may not be V-shaped, may consist of a number of friction vpieces 13, movably locked in recesses in the wearin faces of the followers as shown in Figs. 4 an 5 or in one of each pair of followers. These loose pieces are in the natura of inserts set loosely ir. cavities or housings in the face of the followers, so that the surfaces, whether they be fiat or V-shaped may adjust themselves readily, one to the other, that is to say But as thefollowers move and the contacting surfaces slide with relation to each other in opposite directions, these pieces will be restricted or not permitted to get out of position by reason of the confines of the cavity'in which they are set in the follower, but by having -some little latitude within this cavity on account of the separation, the surfaces can adjust themselves more readily to each other Y and get a more perfect contact.
.Various slight changes might be resortedto in the relative arrangement of parts shownand described without departing from the spirit and scope of my 'invention hence I would have it understood that I do not wish to limit myself to 4the exact construction of parts shown and described, but,
Having fully described my invention what i I claim as new and desire to secure by Letters- Patent, is z" 5o `1. The combination of contacting frictionv elements movable simultaneously and having pivotal mountings located in proximity to each other, and a resisting spring pressing against said elements.
2. The combination of contactingfriction elements movable together in the same plane,
means for imparting a subsequent pivotal' movement to said elements whereby they will lbe moved relatively to each other and a spring pressing against said friction elements.`
3. T e combination of two contacting friction elements, means affording pivotal mountings for the lower ends of said friction elements and a spring pressing against -said .friction elements.

The combination of a draw bar, a yoke and' draft ironsof a. friction element bearing against the draw bar, a second friction elevment contacting with the first mentioned friction element, al spring bearing against the second friction element and means for permitting said elements to turn on pivotal supports located below the same and. supported by the draft irons.
5. The combination of two contacting friction elements normally disposed in an inclined position, means under said elements aording pivotal mountings therefor and a spring pressing one friction element toward the other. A
6. The combination with two contacting friction elements normally disposed in an inclined'position, pivotal mountings for said elements, said mountings being spaced apart and permitting an initial simultaneous movement of said elements and a subsequent pivotalmovement, and a spring pressingone 7.

8. In a friction draft and buing apparatus, 'the combination of contacting friction elements having fixed fulcrums, anda resisting spring bearing against the said friction elements. Y l 9. In a friction draft and bufng apparal tus, the combination with a yoke, of two sets of friction elements, pivotal bearings for each of said friction elementsl fixed to a part stationary with respect to the yoke and friction elements and a resisting spring between said friction elements.
10. In a friction draft tus, the combination of fulcrumed friction elements, each element having a series of beveledfaces contacting with the other friction element, and a resisting spring bearing against said friction elements.

14. In a draft and buing apparatus, the
combination of .pivoted or fulcrumedxfricl tion elements, an actuating device contacting with one element, a s ring pressing^ against the other element, said) points of contact being so located relatively to the fulcrums of the elements as to increase the movement transmitted to the spring beyond that ofthe actuating device.

combination with a cou ler, draft irons and a yoke scoured thereto, of) a pair of friction elements at both ends of the yoke one pair bearing against the coupler` and the other against the end 'of the yoke, a coiled spring supported on lugs on the inner friction elements, and 'fixed pivots or fulcrums for all of said friction elements, su ported b the draft irons.
1S. In a raft and uffing ap aratus, the combination with a coupler, an a yoke securedthereto, of a pair of friction elements vat both ends of the yoke, a springr between the pairs of friction elements, draft irons having shoulders to limit the movement of the .friction elements, and carryingirons providing pivots orjfulcrums for' the friction elements.
19. In a draft and bufiin apparatus, the
