CAR-COUPLING.
SPECIFICATION forming part of Letters Patent N 638,505, dated December 5, 1899.
Application filed June 21,1899.
T0 all whom, it may concern:
Be it known that I, MASON B. GIBnRsoN, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Oar-Couplers, of which the following is a specificatiomreference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in car-couplers.
The general object of this invention is, first and broadly, to provide a locking-bar with means for preventing it from jarring out of locking position in its relation to the knuckle, and, second and specifically, to provide a locking-detent for such locking-block, such locking-block havingalifting-pin loosely connected therewith, so that an initial movement of such pin will disengage such detent from such block, whereby the further movement of such pin will act to lift the locking-block out of locking position.
The second object of my invention is to provide for returning the locking-block to locking position in those cases in which the purpose to cut or couple two cars is suddenly changed to a purpose not to cut or uncouple them; and this feature of my invention has to do with returning the locking-block to locking position before the knuckle has been swung out of locking position, although the locking-block has been momentarily elevated to unlocking position, and this' object is effected by so arranging the lifting-pin, locking-block, and the guide-pin for the latter that by the lateral thrust of the elevated liftingpin it will shift the foot of the locking-block from its supporting-shoulder in the head and allow it to drop down into locking position.
This invention also relates to details of construction and arrangement hereinafter appearing, and particularly pointed out in the claims.
In the accompanying drawings, on1 which like reference-letters indicate corresponding parts, Figure 1 is a sectional view of my improved coupler on the line o@ :I: of Fig. 2; Fig. 2, a side elevation of the same; Fig. 3, a crosssectional view on the line y y of Fig. l and showing the locking-block held in locking position byalocking-dog; Fig. 4, a similar view Serial Nol 721,290. (No model.)
to Fig. 3, showing the locking-dog out of locking engagement with the locking-block and in a position to permit such block to be elevated; Fig. 5, a similar view to Fig. 3, but lshowing the locking-block out of engagement with the swinging knuckle; Fig. 6, a similar view to Fig. 3, showing the manner in which the locking-block is held out of locking contact with the swinging knuckle; and Fig. 7, a detail perspective view of the lifting-pin, locking-block, and locking-dog and also showing their relative relation to each other.
The letter A represents a car-coupler drawbar having a head B. To this head is pivotally connected a swinging knuckle O by means of a pin Dor in any other suitable manner. This-knuckle has a shank E normally projecting within the head and adapted to be locked therein, so that the forward end F of said swinging knuckle may normally stand partially across the forward end of the coupler. Such forward end of the knuckle is provided with a hole or opening Gr for the reception of a pin for use in connection with an ordinary link-and-pin coupling, it being understood that such forward end is bifurcated, as clearly illustrated in Fig. 2, the space for the reception of such link being indicated at H, (see Fig. 2;) but to this special construction I lay no claim, as my invention has reference, among other things, to means for holding this locking-block down in locking position, as illustrated in Figs. l and 2.
The letter I represents a lockingblock sloping or beveled atfits lower end, as seen at ct, to permit its more ready withdrawal from between the knuckle E and guide W and also having an elongated opening or slot, as shown at J, within which projects a stud K, extending from a lifting-pin L, such lifting-pin extending above the upper wall of the head B through the hole M, the hole being considerably larger than the pin. The outer end of this pin is provided with a hole O for the attachment of operating devices. A shoulder P, formed on the pin, limits its downward movement. From this description it will be seen that as the pin is raised the stud K will move from the lower end of the slot J to its upper end in the locking-block, and when still further raised the locking-block itself will be llO moved out of engagement with the inner arm Eot` the swinging knuckle, as illustrated in Fig. 5.
I will now refer to the preferred form of means for holding the locking-block normally in its locking position, so as to preven tit from being raised when it is unduly jarred, as when traveling over rough roads. From Figs. 2 to 7, inclusive, it will be seen that upon apin Q, extending within a hole or opening R in the head B, (see dotted lines in Fig. 2 particularly,) is mounted a locking-pawl F, which extends over the stud K and down upon the lockingblock I and abuts against a stop I. Thislocking-pawlprevents the locking-block from being elevated or withdrawn from its locking position until after the locking pawl has moved out of locking engagement therewith, which is accomplished by raising the pawl K through the littingpin L until the stud reaches the upper end of the slot J, by which time the locking-pawl is moved out of locking contact with the locking-block to permit such locking-block to be elevated. Thus it will be seen that my invention, broadly, has reference tomeans to hold the locking-block in locking position, and specificallyit has reference to a locking-pawl, which pawl may be moved out of engagement with said bloc-k before the block is elevated by the lifting-pin, such lifting-pin carrying a stud projecting within an elongated opening orslotin the locking-block to permit this to be accomplished.
l will now refer to the manner in which the locking-block is normally held out of engagement with the swinging knuckle. Referring again to the pin Q, it will be observed that it passes through the slot T in the lockingblock. While this slot permits the lockingblock to be elevated, as above described, it also permits the block to pivot about said pin, and thereby performa a very useful function, as will shortly appear. Let us suppose that the lifting-pin has been elevated sufliciently to release the locking-block from engagement with the swinging knuckle. In this position the block will swing into engagement with the shoulder U of the interior of the housing B, where it will be held out of locking position until the brakeman cants the lifting-pin to the position illustrated in dotted lines in Fig. 6, which will cause the locking-block to pivot about the stationary pin G and out of engagement with the shoulder U, so that it can again quickly drop into locking position. The locking-block swings into engagement with the shoulder U by reason of the prepo'nderance of weight of the locking-block B being at one side of its pivotal connection of the lifting-pin-that is, on the side away from the shoulder U. From Fig. 1 particularly it Willlbe seen that a guideway W is formed in the inner wall of the housing in front of the shoulder U. This is for the purpose of guiding the' locking-block and holding it more irmly in position. Thus with my invention, while I have provided for locking the lockingblock so that it cannot be accidentally raised from engagement with the swinging knuckle, due to shocks and jars, ttc., and also for holding the locking-block out of locking engagement with said swinging knuckle, it will be understood that such locking-block may be instantly thrown to locking position while the swinging knuckle is in coupling position, such position being illustrated in the drawings. This is of particular advantage, especially when a signal has been given to cut the cars for switching, the., and the signal is suddenly given not to cut them. Consequently without the necessity of separating the cars and then bringing them together again the locking-bar may be quickly thrown to locking position by the brakeman simply eanting the lifting-pin, and thereby pivoting said locking-block about the fixed pin out of engagement with the shoulder U, thereby again coupling the cars, which saves a great amount of time and annoyance.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
