To all whom t may concern,.-

Be it known that I, JOHN E. MULLINS, a citizen of the United States, residing at Magnolia, in the county of Columbia and State of Arkansas, have invented a new and useful Car-Coupling, of which the followingis a specijtication.

This invention relates to car-couplings, and the object of the same is to provide a device of this character possessing certain improvements in construction and operation, all as hereinafter more fully described and claimed, and as illustrated in the drawings,in which- Figure l is a central longitudinal section of the end of a car with my improved coupling attached thereto. Fig. 2 is a front elevation of the end of a car and its coupling, show- .ing the parts in their normal positions with a link locked therein. Fig. 3 is a cross-section on the line 3 3 of Fig. l,showing the uncoupling devices in position when the pin is raised. Fig. 4 is a plan view of the dravhead. Fig. 5 is a horizontal section on the lines 5 5 of Figs. l and 2. Fig. Gis a perspective detail of the three levers and the catches operated thereby.

Referring to the said drawings, theI letter D designates a draw-head, Within which is a longitudinally-moving block B, pressed normally forward by a coiled spring S in a wellknown manner. The front end of the drawhead is of the construction best seen in Fig. -that is to say, its sides project inwardly at I on opposite sides of its mouth, and within said mouth is arranged a number of lips L, which rise and fall loosely upon said proj ections I and which have sharpened front edges, as seen in Fig. l. Below the lowermost lip is arranged a link operating device O, borne normally upward within the mouth of the draw-head by a pair of coiled springs C, which surround the arms of the U-shaped yoke U. 'lhelatter projects upwardly through holes in the bottom of the draw-head, the plate O being secured to its upper ends and limited in its downward movement by a stud or stop P. The body of the yoke stands beneath the bottom ot' the draw-head and receives a finger F, projecting forwardly from and secured rigidly to a transverse rod T, mounted in eyes t' in the draw-head and having operating-handles h at its opposite ends. By this means when the link is iu place the handles h can be operated to adjust its outer end vertically, so as to guide it into the mouth of an approaching draw-head. At the. same time the several lips L permit the link to enter the mouth of the draw-head at any vertical point within reasonable limits, and the plate O when moved vertically raises and lowers the lips L, and with them the link,in a manner which will be clear to any person skilled in this art.

The block B is provided on its upper side with a cross-bar X. Above this cross-barlies a longitudinal arm A, pivoted near its rear end to an upright stud a, rising from the block B and pressed upwardly in rear of said stud by a coiled spring S. The front end of this arm is bifurcated, as shown in Fig. 4, and receives the head of the coupling-pin P, said head being pressed normally forward in the bifurcation by a coiled spring O, surrounding the arm A, as seen in Fig. l.

At about the cent-er of its length the arm A is provided with a downwardly-projecting tooth A', having a rounded front face.

N, Fig. 5, is a bar passing transversely through the draw-head and through a horizontal slot b in the block B, and this bar is provided with a notch n at its center, in which the tooth A stands when the pin is lowered. Then the pin is raised, it will be evident that the rounded front face of the tooth will press the bar N forwardly against the tension of the leaf-springs L', located in the body of the draw-head on either side of the block, and when the tooth has passed bythe bar the latter springs to the rear beneath the lower end of the tooth, whereby the latter, and with it the arm A and pin P, are supported in elevated position. Then alink enters the mouth of the draw-head and drives the block B to the rear, the tooth thereon is moved off the bar and the tooth allowed to drop, and the pin P is thus shot downwardly through the link by the force of the spring S.

Mounted in studs u u at the outer ends of the cross-bar X are the levers V and V, having L.-shaped handles H andll at their outer ends borne upwardly by leaf-springsl and I. The inner end of the lever V is bent upwardly over the arm A and then downwardly at its IOO point, and a link Q is pivotally connected at its ends to the inner ends of the two levers.

l.ivotall v mounted upon the lever 'V at points above the sides ot' the arm A are catches K K, the latter having an Lshaped body, as best seen in Fig. 3, and to these catches be low their pivots are pivotally connected the inner ends of pitmen M M', which extend thence outwardly and connect with the lower ends ofthe handles ll ll.

Pivotally connected to the innercnd of the horizontal arm in the catch K is a pitman mi, which extends upwardly and is connected to the end of an operating handle ll?, pivoted between its ends to the top of the car. The lower ends of the catches are provided with J in wa rdly-extemling poin ts 7.', which are adapted to enter recesses in the upper side of the crossbar X and pass beneath the arm A when properly manipulated.

With the above construction ot parts the operation of uncoupling is accomplished in the following manner: One of the levers Y or the handle ll is operated to move the catches downwardly. 'lhehandle ll'ea-n then be moved to throw the point L of the catch K beneath the arm A, or the handle Il can be similarly moved to throw the catch K into operative position; but if the catches are operated from the top of the ear the downward movement ou the pitman in, tending to throw the point 7s of the catch K outwardly, is resisted by the pitman M and the handle ll. Then the pitman 'm again moves upwardly, the iirst portion of its motion turns the catch K on its pivot and throws its tip 7c beneath the arm A, and the balance of its motion lifts said arm in a manner which will be easily understood.

'lhe letter E designates an elbow-lever ex* tending from the pivotal point 1l of the lever Y and engaging a pin N in abroad notch n. in the outer end of the bar N, and this lever causes the bar to move transversely through the draw-head as the lever 'V is operated.
