"o all wishful-fit muy concern." Re it known ther. l, Aereos Essener, e citizen of the United States, residing et Glevelend, Cuyahoga county, Ghio, lieve inl c vented. new und useful improvements in iCir-Couplers, of which the follovvin is e specification, reference losing had to t e ce coin in ,ving dretvings, in which*- iigure l is e. sectionsl plein of my im coupler showing the parte in locked 1; is section on linee ll--lll ou, 3' is s sectional pien, and melside vier, showing the pc itic'n; 5 is e sectional 1 ig. li sectional side view, showing 'the perte in hnuckietlirovvn position, und. Fig. 7 is e section.- o'n lines Vil: Vil ef l invention reiutes to our couplers and is i@ designed te provide u coupler in which the mejor portion ci the pulling' strains is carried louclr' tlirougli the knuckle-teil and is thence trensijnitted to the coupler heed, and o in which the knuckle pin is relieved of strein, thus enabling the huh of the knuckle und the eersjof the coupler heed .to he made of heevier section through the utilization of u pivot piu.

-To 'this end l provide e knuckle which is so constructed and supported by the coupler heed. that' under the heavy. pulling' strains ci service, inospite of the tendency of the knuckle nieve and stretch, the mainter o'f the preper between the gusrd volition else reietes to the various ich l' li ve particularly described timed he cn. listening to the drawings, .fi indicates the coupler heed, B the knuckle, the lock, D the opener, und E the lifter. The knuckle B is pivotefl to the-heed A oy the knuckle pin 2 and the knuckle pin holes in the ears ,3 are so enlarged that in the operation of the coupier the piu is entirely relieved of strain under all normal draft and bufiing stresses. Upon the uriner surface of the knuckleruil and its er eide is located s pulling Se lug or hook li, the forward surface of which is preferably concave and which coucts with u couvexly shaped shoulder 5 upon the roof el the coupler cavity.'

. To prevent the knuckle teil from bending nose ci the lmuckle will he in' downwardly when it. is under pulling 55 stresses transmitted through the hook l to the 'coupler-.heath and from vclisengeging from' thefshoulder 5, 'I provides shelf 6 on the floor ci' the coupler head. The shelfv 6 immediately underlies the rear end of theco knuckle teil when in locked position, thus giving enough clearance for thev normal movements o the knuckle, and providing en eil'ective support against vertical distortionof the teil and the consequent dise egeentof. the pulling hebk 4 and the Isoull el' 5. V

Upon the upper end lower surfaces ot the knuckle teil, just to the rear of tiie'hub.

7, nre formed inclined projections^8,f8, @D somewhat tf-shaped, which engage correspondingly inclined recess e9, 9f,on the roof anflpiioor of the coupler cad respectively. The projections 8, 8 und recesses 9,9', erel adapted to transmit a portionof the bung and pulling strains, and they also opereteto. prevent the forward end ofthe knuckle' from bending outwardly sway from the guardnrm when subjected to pulling strains.

Under heavy pulling strains .the knuckle 8o has e 'tendencyto pull out of, pleceend.1 with ordinary construction, if the knuckley does pull out of place its hub will travel" sway from the guard am side andthe proper gege between the nose of the knuckle und; the guard arm 1'0l Will not be meintsined. vThis condition, however, is obvieted in nay device, since, if the knuckle pulls forwardly, the forward Walls of the recesses 9:9', and the cooperating forward sides of 90 the projections 8, 8', being approximately parallel with the fece of the guardarmi 10, will prevent. the increasing' of the distance between the nose of the knuckle and the guard uri-n. The bosses er on the couplerf '95 ears 3 :assist these bearings in preventingv lateral movement of the knuckle. Builing bezirings on the coupler head for the knuckle ere provided in the raised bosses e, on the opposite inner ,surfaces of the coupler eers 3, at y on the coupler side Well to the rear of the hub, at e', z on the reer Walls of the recesses 9, 9 through the rear Wells of the projections 8, 8', and et lw, w l on thereer side of theknuckle tail and the side Well of the coupler head respectively.

In the drawings the knuckle is shown in the position which it occupies under a pulling- 3 0 i 'and its legl/l: will 'coperate with thei-arm strain, that is, there is clearance or.back` lashbetween the rear side w of the rknuckle tail and the side wall fw of the coupler head. It will bennderstood, however, that under builing stresses this clearance will be taken up and the surfaces w and w will come -into builing contact. There isno buing contact. however, between the rear end of the knuckle tail and the coupler head, in any position of the knuckle.

The construction and operation of the other parts of the coupler which prefer to use with the parts described above, are as.y follows: v

The lock Chas a lat face 12 for locking engagement with thel front face l1 of the f knuckle tail, anda vertical face 13 on 'the lsiflecgposite the face' l2, for; engagement' with the coupler head.

14 is the leg of the'lock, which eoperates with the opener Dj for locksettng and'knuc- :kle-throwing, hand' 15 is, the locksetting shoulder. thereon. Onfthe forward side of thelock is a rejection 16 which coperates with a shoul er l'n the cou lerheadfor, w rd of the ,lock cavity, so t at whenthe l is lifted by the'lifter E, which has a sldtted cnnectionwith the rear side of the lodk, the projectionll will engage the shouldei' 17 and the ylock, willf fulcrurnfthereabout 18 50i the knuckle thrower D, to swing the' khucklefthrower about ,its pivot 19, so that thefarin-QO will throw open the knuckle- The knuckle engaging end "of the opener? D has a curved surface which .is ydesigned vtovm'lg.- 1, in such a way that it will throw cooperate withv a surface ontheunder side .of the knuckle tailas shown 'in'dotted lines the. knuckle by means of a rolling action and withthe minimum amount of sliding friction, that is, vthe opener is so pivoted with relation to the length of its knuckle-throw ing-"end, that said end is caused to nieve in 4'substantially-.the same line as the line of .movernentof vthat portion of the knuckle tail with which it coperates. This prevents any binding of the pulling surfaces between the knuckle and the coupler head,

during the opening movement.

It is:I obvious that many changes may be made in the coupler which l have described i Witnesses:

and shown herein, without departing from.'

my invention, since- What I claim is:

1. In a car coupler, a coupler head, a knuckle having a tail, inclined projections on the knuckle tail, bearingsy in the coupler head coperating withsaid projections to force the nose of the knuckle as it moves forwardly under. pulling stresses, toward the guard-arm side of the coupler, the corresponding faces of said projections and bearings being arranged tangehtially to the bearing 'on "the hub and ysubstantially parfaces on the knuckle being substantially parallel with the guard arm .face to maintain the nose of the-knuckle substantially at the same distance from the guard-arm nnder pulling stresses.

3.-In a car coupler, coupler head, a

knuckle and apivot pin therefor, ears on said coupler head to which-said knuckle -is pivoted, inwardly projecting bosses integral therewith and concentric with the pivot pinV hole and o less Vdiameter'than said ears, coperati g 'shoulderson the hub of the knuckle, vre'rwardlyv inclined bearings -orming continnaticns `-of said shoulders arranged tangentiallythereto and substantially parallel .to the 'guardwarm face, and extending transvereelyv of l thel knuckle tail on'th upper and lower .surfaces thereof, 'and corresponding bearingsfin t 'i coupler head, sind bearingsucomprielngnnean's for causing' the nose of 'the knuckle to vincve` towardv the guard-arm side when thelmuc-- kle moves forwardly under pulling stress, ARTHUR J.
