Application filed July 26, 1904. Serial No. 218.247. A

draft or bufring gear or rigging for cars.

Theobject off the invention is to construct a rigging' of a' minimum number yof parts and .economical and durable in constrnction.

y Anotliei'"object of the invention is to construct a rigging which 1s provided with rein- .forcing means adapted t'o be positioned within thekeyways formed in the draft-timbers.

t A still further object of the invention is, to

provide reinforcing means forthekeyways, which are formed in the draft-timbers, and to improve the construction of the rigging, which is movably mounted between the drafttimbers. i Y

' With` these and other objects' inv view the invention consists in certain novel constructions` combinations, and arrangements of parts, :as will be hereinafter fully described, illustrated in theacco'mpanying drawings, 'out in the claims hereto appended.

In the drawings, Figure 1 is a plan' View of a mechanism constructed in accordance with the present invention. Fig. 2 is aplan'view i of another embodiment ofthe present invention.` Fig. 3 is avertical central sectional View of the mechanism, taken on. lines A A, Fig. 1, showing the draw-bar removed therefrom. Fig. 4 is a plan view of the keywayliner or housing member, which is adapted to be inserted into the elongated apertures formed in the draft-timbers, into which the cross keys or heads are inserted. Fig. 5 is an end view in elevation of the' front cushioned follower. Fig; 6 is a reverse view of the construction o'f the follower depicted in Fig. 5.

ig. ..7 is a View in side elevation of the `front of the housings 4 is provided with integra-l webs of a follower employed in the construction of the mechanism. Fig; 8 is an end -view of the member depicted in Fig.' 4, the same being shown in its normal horizontal position.

In carrying out the present invention I have provided a pair of metallic keyway liners or irons 1, which are to be positioned within elongated apertures formed in the draft-timbers in combination with draft and buffmg gear means which is positioned between the metallic members 1, secured to the draft-timbers. i

The keyway liners ,or irons comprise in ytheir construction an approximately iiat body portion 2, which is provided ,with parallel iianges 3. extending longitudinally thereof. Said iianges 3 are constructed for the purpose of forming a guideway for cushioned followers, hereinafter described. The iianges 3 extend from the bodyportion 2 upon one side thereof, and integrally secured to and projecting from'the opposite side of said body portion 2 is a plurality of housings 4 4. The housings 4 4 are approximately rectangular in construction and are of sufiicient length to vextend through the apertured portion of the draft-timbers 5 for the purpose of forming a metallic reinforced surface, which is adapted to be engaged bythe cross keys or heads 6.6. The portions44 of mem-ber'l are positioned in elongated apertures, said portions 4 entirely filling the apertured portion of members 5,V thereby retaining members 1 in an assembled. position with drafttimbers5,`without employing bolts or any similar secu ring means. Each 7, forming braces therefor, which are secured 4also to the body portion of member '1, said webs 7 being formed diametrica'lly in oppo- `site positions upon the housing 4. Vhen the key way-liners 1 have been properlypositioned 90' upon the draft-timbers 5`, the anged portions thereof willbe extending toward the opposite member 1, thereby presenting two hanged metallic surfaces which are adaptedto be engaged by the spring-followers and reltain the same in an operative assembled posi- K tion with the other elements employed inthe draft-rigging mechanism. ,A stop Slisformed i to extend.

' way-liner 1.

upon the follower-engaging face of the body portion 2 of member 1. I have shown in the L accompanying drawings a, plurality of aperi tures 9, formed upon 'the forward end of key- 2 Said apertures are constructed l for the purpose of permitting of thepassage l of bolts 10 therethrough for assistingin positively retaining keyway liner or iron inV position.

. After the metallic reinforcing means for the elongated apertures which are formed in the draft-timbers has been positioned it will be necessary for theassembling of the other parts of the mechanism to position within the housings formed upon the forward portion of lmember 1 a cross key or head 6. upon which is mounted a draw-bar 11. The draw-bar is provided with a suitable recessed portion 12, which`is adapted to receive a boss 13. formed upon the front or shank-engaging surface of a follower 14.

The cushioned follower 14 comprises in its construction an approximately rectangular body portion 15, which is adapted to be movably positioned within the flanged portionof the keyway-liners 1. Upon diametrically opposite portions of the body portion 15 there are formed semicircular extensions 16, which are provided with a plurality of parallel lianged integral 'portions 17, which are adapted to extend from portion 16 to the outer engaging face` upon which is integrally secured the hollow boss 13. A plurality of hollow bosses 18 are formed upon the inner or springengaging surface of member 14. The bosses 18 are constructed for the purpose of providing suitable means for positively retaining one end of each of the springs 19 19 in an assembled position therewith. The body portion 15 of follower 14 is provided with a plurality of cells 20.

The rear or auxiliary follower 21 is constructed similarly to the fron t or primary follower` 14, except that upon its outer or engaging surface 22 there is not formed a boss similar to member 13. In this instance two of the parallel webs of reinforcing members 17 are extended at 23 to approximately a central point upon the surface 22, terminating in an oval slot or cut-out portion 24, into which one of the oval edges of member 6 is adapted 1t will be apparent that by means of the recessed web extensions 23 a positive lock is formed for the rear or auxiliary follower when itis in an assembled position with members 1 and rear cross-key 6, thereby preventing any oscillatory movement provided the guideways are worn sufliciently for per-- mitting of the followers to be loosely mounted therein. The springs 19 19 are positioned upon the bosses 18. formed upon the front or primary follower subsequent to the positioning of said follower between the engaging faces of the keyway-liners after the forward cross-key 6 has been positioned within the housings 4 4, formed upon the forward end of members 1 1 when they are in an operative assembled position with draft-timbers 5 5. Subsequent to the positioning of springs 19 19 upon the primary follower the auxiliary or rear follower 21 is positioned such as to permit of the bosses 18 18 to extend into the helical spring 19 19. and then it will be necessary to position the rear cross key or head 6 within the two housings 4 4, formed'upon the approximately parallel members 1 1, carried by the draft-timbers. After the cross-keys 6 6 have been positioned as described the coupling-links 25 are positioned upon the outer end of cross-keys 6 6 and secured thereon by any suitable means which is adapted to be positioned in the aperturedportion 26, formed near each end of the keys 6 6. v

Referring to Fig. 2, the same principle of construction is employed as has been heretofore described for the construction depicted in Figs. 1 and 3. The essential difference between thesc constructions is that instead of employing wooden draft-timbers 5 5, as in the described construction, I employ metallic draft-sills 5, which are provided with apertured portions 27, through` which are passed securing means for retaining the rsills 5 to the central stringers of the car floor or frame. The construction and arrangement of the cross-keys 6 6 lin k-cou pling members 25, and draw-bar 11 in the embodiment depicted in Fig. 2 are similar to that depicted in Fig. 1. The construction of the primary follower 14 and the auxiliary follower 21L (shown in Fig. 2) is similar to that shown in the other [igures of the drawings, except that in the embodiment Fig. 2 the followers 1,4EL and 21a are positioned transversely and not vertically, as is the ease of the preferred construction. The cushioning members 19* are arranged in parallel transverseposition upon followers 14 and 21.

Each of Figs'l and 2 of the drawings depicts a complete draft-bufhng mechanism for one end of each car, and it will be obvious that it will be necessary to position upon each car, near the ends thereof, a similarly-con- IOO structed mechanism when it is desired to couple the car with other cars.

The modus operandi is as follows: After the coupler which is secured to draw-bar 11 has been connected with an engaging coupler l when outward pull or draft is made on member 11 motion is thereby imparted to the front cross key or equalizing pin 6, and subsequently movement is imparted to approximately parallel coupling-links 25 and thence end portion of the housings 4 4 of members l, and after this positioning has been obtained the draft or drawing is exerted directly upon the reinforced surface of stringers 5 5 or sills 5. It will be obvious that by this construction when initial movement is imparte'd to draw-bar 11 pressure is exerted upon the cushioning means instead of directly upon a metallic rigid surface, as would be the case if ting of-the saine to be'mourited upon each* the cushioning means and its followers were obviated from the construction. If the members were of such construction as to extend the entire length of the cars, thereby permitend of equalizing pins or keys 6 6 of each complete mechanism, the drawing upon one of the slianks 11 would, through the coupling-links 25, also cause movement vof the i cushioning means arrangedin the mechanism secured iipon the opposite end of the car.' W'hen the shank 11 is forced inward, the primary follower 14 will compress cushioning means 19 and 19".

It will be apparent from the foregoing description that 1 have provided a peculiar-constructed mechanism which produces a draftrigging to which is assembled a draw-bai' or at certain times a buffer-rigging for the drawbar, such mechanism being advantageous for the purpose of preventing unnecessary wear upon the assembling means for the draw-bar with the draft timbers 'or sills, whether the drawing or draft is exerted upon draw-bar 1l or an inward pressure, the bumping of an adjacent coupler mounted .upon another car, is the cause of movement of the mechanism.

While I have described in the foregoing description the preferred embodiments of the .present invention and have depicted the same.

in the accompanying drawings, it will be apparent thatvcertain alterations, modifications,

and changes may be made in constructing mechanisms according thereto, and l reserve the right to make such alterations, modifications, and changes as shall' fairly fall within thescope and spirit of the claims.
