COUPLING YOKE AND DRAFT ATTACEIMENT.
Application filed June 24,
To all iii/0m it may concert/rt.'
Be it known that l, EDWIN C. WAsHBUnN, a citizen of the United States, residing at Englewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Coupling Yokes and Draft Attachments and l do hereby declare the following'to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a coupler yoke and draft attachment especially designed for use in railway cars.
t is an object of this invention to provide an improved means for attaching the ends of the draft yoke to the coupler head, such. means comprising the use of poured cast metal.
Vlt is a further object of this invention to provide an improved structure of draft frame including the stop members for theA yielding draft gear.
These and other objects and advantages of the invention will be fully set forth in the 'following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which Fig. l is a plan view of 'the draft mechanism;
Fig. 2 is a view in side elevation of said mechanism, a part thereof being shown in section;
Fig. 3 is a vertical section taken on the line 3 3 of Fig. 2; and Fig. l is a vertical section taken on the line 4-4 of Fig. 2.
Referring to the drawings, the usual draft timbers or draft sill members are shown as l. and in the embodiment of the invention disclosed comprise oppositely disposed channel members of standard form. .at the front end of these members are secured channel members 2 having their flanges facing inwardly, said channels being s cured the channel members 1 by rivets or other means which pass through the said channels and through plate members 3 disposed inside of the channels 2 in contact with the webs thereof. The members 2 and 3 are of standard structural material through which the necessary holes may be punched. As shown 1921. Serial No. 480,157.
in l, the channel members 2 are tapered adjacent their front ends to provide suitable clearance for the coupler head. The members 2 and 3 have their rear ends flush and forni stop members for the follower member a which co-operate with the yielding draft gear. f
A rear follower member is shown which co-operates with the other end of the yielding draft gear and the stop members in this follower comprise a pair of standard I-beam sections 6 disposed, one above the other, and connected by their flanges with the draft members l. Interposed between the flanges of the members 6 and members l are plates 7C and these three parts are irmly secured together by rivets or other means, as shown. The webs of the -bea-ms 6 are cut away at 6a to form an opening to accommodate the motion of the draft yoke 7.
A coupler butt or shank shown as 8 eX- tends rearwardly between the membersv 2 and is formed with a head portion l0 which 'is provided at its top and bottom portions with sockets 8a. The draft yoke 7 extends about the yielding draft gear and embraces the followers aand 5 and has its free ends bent inwardly or toward each other to enter the sockets 8, and these ends are then again reversely curved outwardly and terminate near the ends of said sockets, as clearly Ishown in Fig. Flaring holes Bb are formed through the sides of the sockets 8a and holes lc are also formed 'through the sides of the sockets 8, The ends of the yoke 7 are provided with holes extending therethrough in alinement with the holes 8" and the yoke is permanently connected to the member 8 by cast metal which is poured into the socket 8a and surrounds the ends of said yoke. One or both of the holes 8b can be used as a pouringhole and the socket at the open portion can be suitably surrounded with molds or cores to retain the molten metal therein. The metal Hows into the holes 8b and 8C, and results in forming substantially a connecting pin extending through the ends ot the yoke and the openings 8b to tie the sides of the socket rigidly together, the other sides of the socket are also tied together by the metal entering the holes 8C. WTith this structure, owing to the curved shape of the ends of the yoke, the same is firmly and permanently secured to the coupler shank 8 and said ends cannot be pulled therefrom. A filler plate 7a is disposed inside the rear end of the yoke and is provided with lianges 7b projecting at each side of the rear end of the yoke 7 held in position thereby.
The member 8 is formed at its side portions with projecting oblong bosses 8d through which an oblong slot 8e is formed. er key member 9 substantially lills this slot and extends transversely therethrough and also extends through slots 3a through the members l, 2 and 3, which slots, as shown in Fig. 2, are considerably longer than the slot 8e, to provide for the longitudinal motion of members 7 and 8. The key 9 is shown as having a head at one end and a cotter pin 9L passed therethrough at the other end.
F rom the above described structure it is seen that longitudinal draft movements will be transmitted by the coupler shank 8 to the yoke 7 and by said yoke to the followers 4; and 5 which will, in turn, compress the draft gear in either direction, the relative movement between the parts 7 and 8 and the draft frame members being peri'nitted by the slots 3a.
Owing to the outwardly curved. ends of the yoke, when longitudinal stress is placed thereon there will be a tendency to spread the top and bottom sides of the sockets 82. Any such spreading, however, will be absolutely prevented by the cast metal connection extending through the holes 8b. Such a connection as disclosed. between the yoke and coupler head has been found to be so efficient that the yoke member will be broken before the ends thereof could pull out of the sockets in the coupler head.
From the above description it is seen that applicant has provided a simple and yet strong and rugged structure of draft gear.
The parts are of great strength and yet can be made of much lighter Weight than draft gears heretofore constructed.l The use of standard structural material for the members l to 3 and 6 and 7 affords a much cheaper construction than the cast members heretofore used for these parts.
lt will, of course, be understood that various changes may be made in the form, details and proportions of the parts without departing fromthe scope of applicants invention, which, generally stated, consists in the matter shown and described and set forth in the appended claims.
W hat is claimed is:
1. A draft mechanism consisting 4of a yoke member having its ends permanently secured to a head member by means of a filler element cast in place.
2. A draft mechanism comprising a mem'- ber recessed to receive the ends of a yoke,
formed-A and a yoke having its ends disposed in said recesses and permanently secured therein by filler element-s cast in place.
it. draft mechanism comprising` a member having recesses therein to receive the ends of the yoke, and a yoke having its ends disposed in said recesses, a hole for said member communicating with each recess, said yoke ends being bent and disposed in said recesses and permanently secured therein by a filler element cast in place in said recesses and extending. into said-holes;
el. A draft mechanism comprising a couplershank having sockets formed therein, and a draft yoke having its ends curved inwardly land disposed in said sockets and then curved. outwardly in said sockets and secured therein by a filler member cast in place. i l
5. A' draft mechanism comprising a coupler shank having sockets formed vtherein and holes extendingffthrough said sockets, a draft yoke having its ends disposed insaid sockets, andr a metal filler cast in place in said sockets surrounding the ends of the yoke and extending through saidholes to form a rivet.
6. The structure set forth in claim 5, said holes in said sockets being in' alinement and iiaring outwardly, whereby the'ller member cast therein forms a tie member for the sides of said sockets. y
7. The structure setI forth in claim 5, said ends of the yoke having apertures therein through which said fillermember extends.
8. The structure set forth in claim 7, the holes formed in the ends of said yoke and the holes formed inV said sockets being substantially in alinement.
