CAR-COUPLING.

Specification of Letters Patent.

Patented Feb. 20, 1906.

To all whom, it may concern;

Be it known that I, WILLIAM McCoNWAY,

Jr., a Cll3i7l6l1 of the Urited States, residitg at Pittsburg, in the county of Alleghety aid State of Pennsylvania, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will er able others skilled in the art to which it appertains to make and use the same.

My invention. relates to the construction. of couplir gs for railway-cars, and has for its object to produce a simple, efficient, and easily- I 5 mar ipulated device whereby a car or the like equipped therewith may be readily coupled with other cars, Whether the latter be pro vided with couplers of the vertical-plane or Master OarBuilders type or with link or chain couplings or with coupling devices of the character of this invei tion.

To this end my invention, generally stated, may be said to reside in a construction wherein a suitably-formed hook or equivalent linkengaging device is pivotally mounted upon the head of a car-coupler of the vertical-plare or Master Car-Builders type, said hook memher or link-er gaging device being adapted. to actuate and to control the movements of the usual coupler-knuckle and being itself restrained in locked or coupled position by means of said knuckle and its locking mechanism.

There are other features of invention residirg in particular combinations and elemental corstructiot, all as will hereinafter more fully appear.

In the draWi-r s chosen to illustrate the preferred form of my invention, the scope whereof is pointed out in. the claims, Figure 1 is a plan view of a coupler embodyirg my invention shown in. confection with the adjacent portion of a car, the relative positions the severalparts occupy when the link-engagiig member is it; locked or coupled position being shown full lir es and the open or urcoupled position of the link-engagii'g member at d the knuckle being shown in dotted lines. Fig.2 is a side elevation of the coupler and a portion of the end of the car to whichit is attached, the parts beir g in the coupled position illustrated in Fig. 1. Fig. 3 is an inverted planview of the coupler, the

several parts being positioned preparatory to couplii': g with another car provided with a vertical-plane coupler or with a coupler of the form of the present invention. Fig. 4 is a vertical section taken in the plane of the lire 4 4, Fig. 1, illustrating one form of lock, knuckle, and knuckle-opexirg mechai' ism. Fig. 5 is a view similar to Fig. 1, but illustrating a modified form of myinvention. Fig. 6 is a front elevation of the modified form of my invention illustrated in. Fig. 5, the parts being shown in the positions they occupy when the link-ergaging member is in locked or coupled position. Fig. 7 is a plan view of a coupler embodying my invention, illustrating a knuckle and locking mechanism of different forms from those previously shown. Fig. 8 is a vertical section of the coupler shown in Fig. 7, taken in the plane of the line 8 8 thereof. Figs. 9 and 10 are a plan and side elevation, respectively, of a coi'struction embodyijg my invention, the coupler-head beirg attached to a plurality of stems.

Like symbols refer to like parts wherever they occur.

I will 110w proceed to describe my invention more fully, so that others skilled in the art to which it appertains may apply the same.

In so far as this device corresponds to couplers of the vertical-plane type it is obvious that any of the various well-known forms may be employed.

In the drawings, 1 is a coupler having a shank 2, which is attached to suitable draftrigging appliances (not shown) in any desired manner, the coupler being supported. at the forward end of the car by the carry-iron 3.

The head of the coupler, which may be of any usual or particular form desired, is provided with a knuckle 4 of such configuration as to properly cooperate with the form of head and locking mechanism employed, said knuckle being pivotally attached to the head by the knuckle-pin 5 or in other suitable manner. A look or locking mechanism 6 is provided for the knuckle, the said knuckle and its lock being formed in any desired or well-known manner to coact with each other, and, if desired, the mechanism may be adapted to perform other functions, such as supporting the lock in unlocked position until the knuckle is subsequently opened, locking the lock against an accidental unlocking or automatically opening the knuckle, all in a manner well known.

In the constructions shown in Figs. 1 to 6, inclusive, the vertically-sliding lock 6 is of a form adapted to coperate with a knuckleopener and lock-set or lock-supporting member 7, and for this purpose is provided with a notch or cavity 6 and with a lug or projection 6 below the same. The lock-set and knuckle-opener member 7, which is preferably secured in the coupler-head in such manner that it may have a slight freedom of movement in all directions about its pivotal point or pivot-pin 8, is provided with a plu rality of lugs or fingers, one of which, 7 is adapted to enter the notch or socket 6 of the lock to su port the same in an unlocked position an is also adapted to be engaged by the lug or rojection 6 of the lock to cause a rotation of the member 7 when the lock is raised above a certain point. The lug or finger 7 of the lock-set and knuckle-opener member 7 normally stands slightly above the knuckle and in the path of movement of the double inclined projection 4 whichis formed upon the tail of the said knuckle 4. The depending finger 7 with which the member 7 is provided, extends downwardly behind the tail of the knuckle 4, and when the said member 7 is caused to rotate through the operation of the lock 6 engages the rear of said knuckle-tail to cause an outward rotation or opening thereof.

In the construction shown in Figs. 7 and 8 no mechanism is provided for performing either the function of setting the lock preparatory to opening or for automatically opening the knuckle. The lock 6 shown t erein is a vertically-sliding in having an inclined or beveled face a, tl fe tail of the knuckle 4 being so formed that it engages said inclined face upon a closing or locking movement of said knuckle, whereby the lock is forced upwardly to permit the knuckle-tail to pass, the lock thereafter falling by ravity in ont of said knuckle-tail, and thus Iocking the coupler.

In connection with the lock shown in Figs:

7 and 8 a well-known form of device for preventing an accidental unlocking thereof is illustrated. This device I) is housed within a slot in the lock, its lower end extending beneath a portion of the coupler-head when the lock 6 is in locked position. When, however, the lock is raised throu h the agency of the uncoupling-lever 9, the st movement of the latter causes the withdrawal of the head of the auxiliary locking device I) from beneath the adjacent portion of the c oupler-head, the lock being thereafter freely raised by the further movement of the said uncoupling-lever.

The uncoupling-lever 9, by means of which the lock 6 is caused to assume an unlocked position, is or may be of the usual and well} known form and may be connected to the lock 6 in any suitable manner. Preferably, however, the connection 10 between the lock 6 and uncoupling-lever 9 consists of a plurality of relatively slidable parts 10 and 10, which are telescoping with respect to each other in such manner that the opening for the bight of a coupling-link between the hook 11 and lock 6 in a construction such as shown in Figs. 1, 2, 3, and 4 is not impeded.

While the connection 10 may be formed in any desired manner, it is preferred to rivet the parts 10" and 10 thereof together after they are in position by upsetting the end of the member 10 to form a rivet-head.

Referring now more particularly to the novel features of construction which form operative combinations with parts of a verticalplane coupler of such character or functions as heretofore described, 11 is a link-engaging member which is preferably pivotally mounted upon the guard-arm side of the couplerhead between perforated lugs P 1 integral with the latter, a pivot-pin 12 passing through said link-engaging memberand said lugs. The said link-engaging member 11 preferably consists of a horizontally-extend- 1ng arm 11*, a knuckle-actuating portion 11 and a hook or equivalent portion 11.

The horizontally-extending arm 11, the inner contour of which may conform to the con tiguous face of the coupler-head, carries at the end opposite its ivotal point the vertically-extending knuckle-actuating portion or member 11 the latter being preferably of general cylindrical or columnar form and integral therewith. The hook portion 11 or equivalent device for receiving a couplinglink may be attached to or formed on the link-engaging member 11 at any suitable point, but is preferably integral with the knuckle-actuating portion 11? in order that the draft may be maintained central or approximately central of the device.

Two forms of the hook member 11 are shown in the drawings. In Figs. 1, 2, 3, 7, 9, and 10 the hook member 11 rises vertically from and is preferably formed integral with the knuckle-actuating portion 1 l of the linkengaging member 11, while in Figs. 5 and 6 said hook 11 extends horizontally outward from the knuckle-actuating member 11*,-

passing through a suitable slot or bifurcation in the face of the knuckle 4.

As a preferred means for controlling the movements of the link-engaging member 11 a horizontally-extending controlling-lever 13 is pivotally mounted upon the coupler-head, so that it has the same axis of rotation as the said link-engaging member. For this purpose said rotatable lever 13 may be formed with a boss 13, through which passes the pivot-pin 12, upon which said link-engaging member 11 is mounted, a nut 14 being em- ICC ployed to retain said lever in proper position. One arm of the lever 13 extends toward the knuckle-actuating portion 11 of the link-engaging member 11 and is provided with a vertical lug 13*, having a reduced cylindrical extension which enters a corresponding socket or cavity in the base of the said knuckle-actuating portion or member 11 The other arm of the controlling-lever 13 is preferably formed with a slot 13, adapted to receive and form a pin-and-slot connection with the arm 15 of the hook-coupling-operating member 15, said slot 13 being preferably of cam form to more easily permit the cooperation of the parts and to permit a complete actuation of the said lever .with a comparatively small movement of the operating member 15.

The hook-coupling-operating member 15 is preferably a bar or rod having an arm 15 for engagement with the slotted arm of the controlling-lever 13 and having handholds 15 at each end thereof. As a means of attaching the operating-bar 15 to the car suitable stirrups or hangers 16 may be employed, such hangers being preferably of sufficient width to permit a slight lateral movement of the said operating-bar 15 in the direction of length of the car, whereby the arm 15 of such bar may accommodate itself to the various positions of the slotted arm of the lever 13 without binding upon the same.

The operating member 15 extends transversely of the car, so that one of the handles or handholds 15 is accessible from each side of the car.

In the construction shown in Figs. 9 and 10 sufficient only of the novel features of my invention have been illustrated to show the ap plicability thereof to couplers of the type wherein the head is flexibly attached to the draft-rigging appliances, as by means of a plurality of suitably-formed stems 2 which are pivotally connected to said coupler-head.

The construction being substantially such as hereinbefore pointed out, the operation of the device will be as follows: When the several parts of the device are in the relative position illustrated in full lines in Figs. 1, 2, 4, 5, 6, 7, 8, 9, and 10, a coupling may be made with a link. In such position the bight of a link may be engaged with the hook 11 of the link-engaging member 11, the lat ter being locked in position by the engagement of the knuckle actuating portion or member 11 thereof and the knuckle 4, said knuckle 4 being itself locked, and therefore restrained from outward rotation by the lock 6, which obstructs the path of the knuckletail. If now the parts are in a link-coupled position, as just described, and it is desired to make a coupling with a car equipped with a vertical-plane coupler of the Master Car- Builders type or with a coupler of the character of this invention, the uncoupling-lever 9 may be manipulated to bring the lock 6 to an tion, and as the latter engages the knuckleactuating portion 11 of the link-engaging member 11 such link-engaging member is rotated horizontally outward to an open or uncoupled position in which it does not obstruct the coupling movements of a knuckle, such as 4. As the link-engaging member 11, bearing the hook 11", is rotated to an uncoupled position the knuckle 4 is also opened through the agency of the knuckle-actuating portion 11 of the said member 11, the latter pressing upon the outer end of the knuckle 4, with which it contacts, until the knuckle is substantially fully opened. Such open or uncoupled position of the link-engaging member 11 and knuckle 4 are illustrated in Fig. 3 and in dotted lines in Figs. 1 and 5. When the link-engaging member 11 is in its open or uncoupled position, the device may be coupled by impact with a vertical-plane coupler of the Master Car-Builders type or with a device such as this invention, in which the linkengaging member is also in an open or uncoupled position. In either case the knuckle of the coupler on the other car is caused to engage the corresponding knuckle 4 in a well-known manner, the lock 6 assuming a locked position when the said knuckle is fully closed, and thus completing the coupling of the cars.

It is to be noted that the knuckle 4 of this device after having been opened, as above described, may be closed or brought to a coupled position independent of and without actuating the link-engaging member 11, the latter having been rotated sufficiently far to one side to be clear of the path of the said knuckle 4 during a closing movement thereof.

Should the parts be in an open or uncoupled position and the car with which a coupling is to be made be provided only with a link or chain coupling, the link-engaging member 11 may be returned to and locked in a coupled position by moving the hook-coupling-operating member or bar 15 in the proper direction to-cause the slot-engaging arm 15 thereof to rotate the lever 13 about its pivot 12. Such rotation of the controlling-lever 13 induces a corresponding rotation of the coacting link-engaging member 11, the knuckleactuating portion 11 whereof forces the knuckle 4 to a closed position by impinging upon and forcing the tail of said knuckle inward while itself moving to a closed or coupled position. When the knuckle 4 is re- IIO " the knuckle 4 being acted upon by the tail of the latter. So, also,by a mechanism such as this the knuckle 4 may be rotated outward to an open position independently of the linkengaging member 11 when the latter is in open or uncoupled position.

The operation of a mechanism of this character such as heretofore described is as follows: The lock 6 being lifted through the manipulation of the uncoupling-lever 9, the lug '7' of the member 7 gravitates into engagement with the notch or cavity 6 of the lock when said lug and notch come into apposition. In this position. of the parts the lock is maintained in an unlocked position until the knuckle 4 is subsequently opened. As the knuckle4 opens the double-inclined lug 4 upon the tail thereof engages the triplug 7 b of the member 7 and rotates the lug 7' backwardly out of engagement with notch 6*, the lock 6 then dropping upon the hook portion of the tail of the knuckle and being supported thereon until the knuckle is again returned to a closed position, at which time, the support of the tail of the knuckle being re moved, said lock6 drops in front of the tail of the knuckle and locks the same. If the lock 6 is raised sufficiently to cause the lug 6 thereof to engage the lug 7 of the member 7, the continued upward movement of said lock Will cause an extended rotation of the lock set and knuckle-opener member 7 about its pivot 8, thus causing the depending finger 7 thereof to engage the rear of the knuckle-tail and force said knuckle 4 to an open position. When the knuckle 4 is thus opened, the lock 6 drops upon the tail of the said knuckle and is supported thereon until returned to a locked position by the closing of the knuckle, as before described.
