I Speei ficatiop forming part of Letters Patent No. 138,405, dated April 29, 1873 Reissue No. 8,153, (la-ted April 2, ,1878; application filed February 7, i878.

To all whom it may concern:

Re is known that I, ELI H. JANNE-Y, of Alexandria,connty of Alexan(lria,and State of Virginia, have invented a new and useful Car- Goupliig, and I do hereby declare that the followi g is a full and exact description of the same, reference being had to the accompanyingv drawings, and .to the letters of reference marked thereon.

This invent-ion relates to that class of carcouplings which may be termed twin couplings .-thatis, those in which the coupling parts, per se,are identical in construction and dide'rent species of the genus of hook-- couplings, which may be'properly designated.

by the term pivoted nose.

Its novelty consists, mainly, first, in making the nose, or that part which projects laterally beyond the inner line ofthe shank of the hook, independent of the shank itself, and in pivoting the same theretoin such manner as to be capable ofturning from the inner side of the same outward beyond the inner line of the shank, for the purpose of opening the entrance into the hook-recess; second, in'the combina tion, with a pivoted nose and rigid shank, of a guard-arm for preventing theseparation of thevparts in a lateral direction when the same are"coupled;-and, third, in the combination,

with a. pivoted nose, of a lever'arm and automatic mechanism forlocking the same in place.

In the drawings, Figure 1 represents a perspective view of the draw-head proper; Fig. 2, a perspective view of the rotary hook and pivot-pin; Fig. 3', a sectional elevation of the lockinglever; Fig. 4, aplan view of a. single coupling complete; Fig. 5, a front yiew-of the same; Fig. 6, a plan view of two couplingsin position for coupling; Fig, '7, a plan view of two couplings united; Fig. 8, a plan view of the same. in the position assumed in turning curves; Fig. 9, a plan view of two couplings brought together without uniting; Fig. 10, a plan view of two couplings, each of which has its movable portion in its open position; Fig.

11, a transverse section of a single coupling; andFigs. 12 and 13,- drawings illustrating the principle of operation of the coupling.

To enable others skilled in-the art to make and use my invention, I will now proceed to describe fully its construction and manner of operation. I

-A, Fig. 1, represents the draw-head-proper,' which may. be constructed generally in any suitable form. ever, with an extended portion, a, which projects forward from the front face of the main portion sufliciently far to form a suitable recess, n for receiving the proper parts of the fellow coupling. This extension, which is rigidly united to the main portion, forms, in fact, a shank for supporting the'independent hooknose hereinafter described. a represents a recess 'centrall y located on a vertical line through the shank a, nearits front end,'which It is essentially provided, how

is adapted to receive the hub of the pivoted nose before referred to. tical openings extending through the ears of the shank a, which are adapted to receivethe a a represent verpivot-pin upon which thehub of the pivoted nose rotates.

The draw-head is also provided, upon that side which is opposite to the extension a, with an extended portion, a, which projects for- .ward from the main portion of the draw-head beyond the transverse line :10, Fig. 7, reached by the extreme end of the opposite coupling, when thepa-rts are coupled andunder draftstrain, as shown, for the purpose of preventing absolutely, under any circumstances, the separation of the "coupled parts by lateral movement. This extension also, by means of its inclined face, serves as a guide to properly direct the parts as they come together.

a Figs. 1, 5, and 11, representsahorizontal recess formed .in the front end of the drawhead, which is adapted to receive the leverarm 7), Figs. 2 and 11, of the pivoted nose, as shown. extending about the front edges of thedrawhead upon its upper andlower faces, which is 0. represents a projecting Fib or flange.

tion, as shown-also. in Fig.

and 6,

employed for the purpose of enlargiug the .bearingsurfaceof the face without adding materially to the weight.

a a, Fi'gs. 1 and 7, represent slotted open-- ings in the upper and lower faces of thedrawhead,--wliich are adapted to receive the lock ing-leveij hereinafter described.

B represents whatma'y be termed-a hooknose,-consisting of avertical bar, b, nearly triangular in crosssectio'n, the inner -face b ofwhich is curved to correspond with the circular and of the draw-head shank a, against whichit bears, as shown in Fig. 4, the bear ing-face b of which is provided with proper curves -for permitting the parts to interlock when in their coupled p0si tion,'as shown in" Fig. 7, and the outer face b? of which is curved to furnish a proper inclinedbearing-snrface' to -fit properly the recess of the opposite coupling when the parts are in their coupled posipurposes hereinafter explained.

\ b,'-Fig. 2, represents theLhub of thehooknose, which is secured to the vertical center of the same,- upon its inner face, and is provided with a vertical opening, b, for the pivot-pin;

the "hub bf at'or' about right angles'to the nose, which-is provided at, its rear end with a beveled' orinclined face, b,-as shpwn. The ..hub

will be referred to under. separate heads, as follows: The operation in coupling, injuncoup? ling, in boiling and.=in-turning.icurves.,

The operation in coupling: The ends--of.ad-.

jacent cars having each been provided with one of the couplings described, the two may be united for the purpose'of attachingth'e' cars together, in the following manner: The

pivoted nose of one of the couplings,'before the cars come together, shouldbe rotated on its. axis in anloutwarddirection into abo'nt the position shownin. Fig.. 6', for the purpose of opening the entrance intoi'the recessa oi the draw-head; to admit the proper part ofthea fellowcoupling. When tu'rnedintothis tion, the lever-arm, :formin' a l 'igid-portionoi the arse, iscansed to eaten across the month- ,"and for other motion of the C, Fig. 3,-represents a' pivoted lever and 'cv a spring adapted, when free to act, to move. the leveri-nto proper position to lock the lever of the entrance in proper y-position to beacied upon by the-entering portion,as shown. When thus arranged, the-carsmay be brought to 'gether in the same manner'as when other antomaticcouplihgs are employed-that is,with sufiicient forceto-canse the parts to engage 'with each other. By this action the leverarm, which extends across the entrance, will be struck by the entering; part of the fellow coupling; and be consequently swung around on its axis intothe horizontal recess of the draw-head; The rearward movement of thisarm continues until itsextreme rear end has passed beyond the locking-lever, as shown in Fig. 11', the latter being moved back from its normal position, as indicated in dotted lines Fig. 3, to. permit -its passage by the inclined face b." By the-re't nrn movement of'the lock-,1 ing-lever to its normal position through-the action of )its spring c, 'afterthe 'levervarm .has 7 passed beyond it, aba'rrier is placed in the path of the'latter, so that its returnis i-mpossible.

o'ted nose attached tothesame is-turned in behind the locked nose of the-fe1low;- coupling as the latter enters the through-the. open entrance, and'is carried to bear against I its inner-face,- as shown in Fig. 7.

'Being locked-in this position by means, of its leven'arm, as before-described, the anion is; complete,- andseparation cannet occur; The-- -,enhir"e' coupling,-wlien one of the noses islocked,

is much the same as when any rack-bar is employed to revolve a piniontbat is, the teeth of the rack bar in its longitudinal movement successively engagew' ionand-causerevoiution. 1 From the nature'ofthis construction and op.- eration it follows that both of the parts a a? vof the rack-bar assist in the rotation ofth'e pinion-segment or pivotednose, the'ffirst, :0, act- -ing principally to give the initial movement, before described, and the latter, a, ,thefinal' movement, because atthistime thegtooth or:

itself. The nose alone, it will be understood,

is not a hook, but only'a part of ,one,'it being essential thatthe draw-head should unite'with the same to make it complete. The movable. portion B has also been considered'as a pin-o ion-segment, the axis of whichis simply supported by the draw-head; The nose portion, in this view of the case,is not a hook, but simply a pinion-tooth of modified form, the leverarm being another tooth of the same series. The movable portionBasawholethat is, as

united to its lever-arm-rnay be considered as a" simple hook, Fig. 13, which is pivoted in the angle of its.bend in such manner that a line through its pivotpoint will separate it into the two parts common to every hook of shank y and 'nose or, head In-this view of the case also the nose alone does not constitute a hook, for if the shank be omitted all resemblanceto alhook is entirely destroyed. V

The guard-arm serves, by means of its in'- clined face, to guide the parts properly as they come together. If desired, both of the movable parts of the coupling may be opened to effect a coupling,

as shown in Fig. 10, in which case the operation will be similar to that of two pinion-seg- .menrs turning on each other.

.When the parts are co'upled,aceidental sep' 1 aration is absolutely impossible while the cars remain on the track.- y

Separation cannot occur in a longitudinal direction, because the bearing faces-of the hook-nosesoverhang each other. Separation cannot occur in a lateral direction, because each guard-arm p ojects beyond the end ofthe felloycouplin'g L .der all circnm stanc'eaand prevents movement to either side.

The operation in uncoupiingiWhen it is desired-to detach the carsfrom each other, either one of the levers C is drawn back from its normal position sufficiently far to release the end of the leverarm. By this means the pivoted nose attached thereto is unlocked,and, being free to move, consequently offersnouesistance to the withdrawal of the other hook.

The operation in bufiing: The impact of the cars in buffing is taken by the'hook-heads, shanks a, and opposite draw-head recesses, so

that no auxiliary devicesare required for'this, purpose.

The line of curvation of the project ing portion of one draw-head and the recess of the other, in which it rests, are nearly the same, so that a large bearing surface is furnished to take the boiling-thrust.

, The operation in turning curves: Whenthe coupled parts lie in the same straight line, an

. height.

' open space, :8, Fig. 7, will tie-observed between the hook-head and adjacentface of the draw-head. By means of this space the head of the hookvis permitted to swing upon the bearing-,fa'ce of its nosez'as, a pivot-center, as

shown in Fig.8, topermit the couplings to change position relativelyto each other in passing curves. Bymeans .of this construction freedom of movement isobtained without longitudinal play, and without the-possibility of accidental separation.

If desired, separate cars maybe brought together at anytime without coupling by aim, ply'locking the nose vof each, as shown in' I igffl.

T Some of .the ad-vantages'of thedescribed construction areas follows: Theparw are readily connected with each other, and-when united are soclose'ly interlocked as to prevent longitudinal play. This is accomplished by the interrneshing of the tooth'i af, Fig. 12, of the pinion between the teeth 02 a. of the rackbar. The. nose of the coupling also, when in its open position, does not projectbeyond the outer line, is", Fig; 6, of the draw-head, in consequence of which it is possible to employ an. extended guard-arm, which ,will absolutely prevent separation in a-lateral direction under all circumstances. Perfect freedom is'permite' ted in turning curves withontunduetstrain on any part..- It is adapted for cars of varying Having thusfully described my invention,-
