. To all whom it may concern.- A v A Y Beit known that we; MADIsQN J. LORRAINE and CIiARLEs T.. AUBIN, of the eityof St. .Louisg in the lSuite of Missouri, have jointly invented a new and useful Improvement in Oar-Couplings, o f which the following' isn full, clear, and exact description. l

Our invention relates to thatA class of carcoupling'sknown'as vertical plane, and havrg ing aY pivoted outwrdlyopening coupling head or clutch and an extended arm orbu'er. The object of our invention is to provide a vertical-plane-coupling free'from complicated parts, locking by means of a simplelautomatic x s -gravity-pin, requiring no adjusting and made in onepiece; to provide a'verticatplane coupling ih which, when the coupling-head is unlocked and released', said eoupling-head,' by Vreason of ,its .own weight, will tn rn outwardly and open', and thusnautomatically sethitself in position to effect'a coupling with a similar opposing coupling-head, whichmay be either o pcn orelosed to provide anilnproved and slmpliedmeans ot setting noty to couple; to so constructand arrange thecouplinghead that it will be unusually strong,'and to make a coupling .that will perform the work underY 'fall circumstances, as well on the sharpest f curves as on a tangent, 4and with they greatest variations in height of theopposing parts-in lact,` toJprovide a ear-coupling that-will be simple in :consti-notion, automatic in action.' und free from springs and' superfluous yund loosey parts, that willv combine strength and durability with simplicityandfperfection of action.

The arm A' of coupling-headV is divided, so 'as to receive link when coupling with common draw-head.

The ctionof coupling is as follows: Should the two similarly-constructed draw-heads approach each other in -the positionshown in Figs. 9 and 10,the arm A of the closed coupling-head encounters the point of t-he arm L of `the pen coupling-head, turning it partly inward, when the point of the arm A of the open coupling-head then encountersthe concave face of the buffer-arm B, which forces it compl'etely aroundto the limit. of its inward movement. As the coupling-head turnsinwardly, the projecting knob or pin D' being at the commencement of this movement at the top of the inclined or curved groove D,the upper side of the groove travels up and across the pin D', and'by this movement raises the coupling-head up into a space left at .the top to allow for this upward movement. At the same time the coupling-head is turning, andv raising the pin H, which rests on top of the inner arm, L, is

operatgnided in the guide, groove G toward the hole F', and when it is'oversaid hole the pin Hfalls through it and into the hole F, andI thus se The rib S', fitting into the recess S, is intended to give' the coupling -head a solid bearing against draw-head when the coupling-head is locked by the pin H.

For uncoupling, the lever-'aria N, or any suitable dcvce,is used. To uncouple,the arm N is raised,and this 'in turn, through the chain M, raises the pin H. The coupling-head has then nothingto retain and support it, and as the opposing head ldraws away from it the action of gravity draws the coupling-head down into the vacant space beneath, and as it falls, by reason of the top of the groove D traveling down ajnd across the knob or pin D', the couplinghead turns and opens andis set into position for another coupling. Should b oth heads he closed when desiring to make a coupling, the pin H israised, and the automatic action of the coupling-head immediately opens and turns it vready for coupling. After the coupling-head is operi the pin H is allowedto fall, and rests (in the position shown in Figs. 7 and 10) in'the groove andou top of the arm L of the coupling-head. Should it be'neeessary to set not to couple, the lever-'arm N is raised and pushed or pulled on top of the block P,

Fig. 9, and as this keeps the pin H in a raised position the coupling-head can therefore not be locked and a coupling cannot be e'ected.'

its center is threefold: First, if the coupling- -head was otherwise pivoted, by reason of its shape, when uncoupled, the arm L ofthe unlocked head would bind with arm A fof its. neighbor and prevent uncoupling with fa cility, and this it would do' especially on curves; second, if the coupling-head werepivoted back of its center or in the arm -L,-it would then be necessary to open bothheads to either couple or uncouple, which would bc unnecessary and faulty; third,i f theycoupliughead were pivoted in its forward arm, A',when the coupling-head wasentirely open, the arm L would then come entirelywithiout the drawhead, and there would be nothing to support the locking-pin in a raised position, .and it would accordingly fall, and when coupling Ait would be necessary to construct some mechanof this class are cut away, weakening them at the place where strength is most requsite,are by this construction strengthened, and the metal is distributed at the points most needed,

'and when the coupling-head is removed froln the draw-head,'which can bcdone by withdrawing the pin E, the remaining portion of the construction constitut asutiicicnt means ot' itself for coupling with anycenter-draft coupling.
