18 Claims.
This invention relates to automatically interlocking couplings, particularly for toy railway cars, and to apparatus for automatically uncoupling selective pairs of cars as they pass a given place or station along the track. One object of the invention is to equip toy cars with couplers which will permit the coupled ends of adjacent cars to ride in close proximity as is desirable in model forms of stream line trains.
Another object is to provide a compound coupling of this nature in which plural couplers or draw hooks are employed in the same coupling mechanism and are free from cramping during their simultaneous coupling and uncoupling actions and also when one car is towing another car along curved as well as along straight stretches of track.
Another object is to provide coupling devices at each end of each car made of like parts and capable of mutually coacting in universal manner so that either end of any car may thereby be coupled to either end of any other car or to a toy locomotive or other rolling stock of a toy train.
A further object is to avoid the use of springs in couplings having the above characteristics preferably by providing two weighted draw hooks so arranged that both have to be lifted to eifect uncoupling.
A further object is to provide a coupling in which draft engagement may be had simultaneously between plural catch studs and plural couplers or draw hooks at spaced points in a common coupling mechanism and in a manner to insure dependable interlocking action and avoid tendencies to accidental uncoupling.
Avstill further object is to provide tripping means stationed along the track which may selectively be conditioned to cause uncoupling of adjacent cars by simultaneously lifting a plurality of couplers or draw hooks as they pass the uncoupling station.
' The foregoing and other objects of the present improvements include the general aim of simplifying the parts as heretofore constructed and ar` ranged in toy couplers, and these objects will appear in greater detail in the following description of illustrative embodiments of the invention, in which description reference is had to the accompanying drawings, wherein:

Fig. '7 shows on an enlarged scale the coupling of Fig. l together with a portion of the track and tripping devices that may be associated therewith for operating the coupling to disconnect the cars of Fig. 1.
Fig. 8 is a plan view taken in section `on the plane 8 8 in Fig. 7.
Fig. 9 is a view taken in central vertical section on the plane 9-9 in Fig. 7 looking in the direction of the arrows.
The iioors Ii) and II of adjacent car bodies are carried on their respective trucks I2 and I3 and swingably connected thereto by the vertical king bolt or pivot pin I4 which penetrates the circular table I5 or I5' of each truck and also the car floor, and whose head end and riveted over end give only suicient axial room to permit free relative swinging between the truck and the car body. Y V
Each truck table has secured against its under surface by the head of pin I4 a draw bar which is designated as a whole by I6 on the car at the left of Fig. l and which is designated as a whole by I6 on the adjacent car at the right thereof. Associated parts of the coupling are correspondingly designated by numerals unprimed and primed accordingly as they are carried by the draw bar I5 on car I0 or by draw bar I6' on car II.
Each draw bar comprises a horizontally disposed iiat strip of metal as best shown in Figs. 3 to 6, inclusive, in which the portions I'I or I'I between the bends therein produce an offset so that the free end I8 or" I8 of the draw bar is disposed at a lower level beneath the car floor than is the mounted end I 9 or I 9. This mounted end has the hole 20 or 20 fitting the pivot pin I4 or I4', and also the slot 2| or 2| which is snugly engaged by a tongue 22 or 22 bent down from the metal of the truck table I5 The free end portion I8 or I8 of the draw bar ,y
is reduced to less width than the mounted portion and is provided with the downwardly bent terminal lug 23 or 23 which carries a horizontallyV extending pivot and catch stud 24 or 24' having the head 25 or 25 and whose shoulder 26 or 2S of large diameter turnably its and occupies a hole in lug 23 and whose shoulder 2'!` or 2l of smaller diameter snugly ts a hole in the hook- like coupler 28 or 28 and is peaned over thereagainst" at 29 or 28 to make the coupler rigid with its pivot stud. rihe latter remains free to turn in the draw bar lug 23 because its shoulder 2S is longer than the thickness of the metal of the lug 24.
The coupler or draw hook 28 is thereby pivotally H mounted on the draw bar in a manner to swing freely in relation thereto within certain up and down limits. The up limit of swing of the coupler is determined by the engagement of its shoulder 3B or 38 with the shoulder 3l or 3|' on the draw bar. The down limit of swing of the coupler 28 or 28 is determined by the engagement of the extremity of its tail end 32 with the under surface of the free end portion I8 of the draw bar. Thus the hook head 33 or 33 of each coupler may swing from its full line position to its broken line position in Fig. 1. This hook head of each coupler contains a notch 34 or 34 whose width is considerably greater than the further reduced diameter of the catch stud 24 or 24' in its elongated portion 35 or 35.
Between its tail end 32 and hook shaped head portion 33, the coupler comprises a plate-like body portion 38 4or 3S' of enlarged area for weighting each coupler and giving the hook head thereof a dependable tendency to drop and assume its normal or full line position in all figures of the drawings. At the bottom edge of each coupler body the Vcurved flange 31 or 31' is rigidly carried and projects in the opposite direction from that in which catch stud 24 is elongated at its free end. As shown in Figs. l and '7, flanges 3l and 31 may be side by side in line with each other lengthwise of the train when the hook heads 33, 33 are pulling respectively on their catch studs 24, 24 as one car tows another along the track.
Figs. 7, 8 and 9 show apparatus with which the track may be equipped at any station for simultaneously lifting both couplers 28 and 28 and automatically disconnecting them respectively from catch studs 24 and 24 as the cars l) and Il pass this station on the track. Such apparatus may consist in a rod 4D having bearing in the sheet metal web of each of the track rails 4I` and spanning the space therebetween. Pinched up ears 42 provide the axial thrust constraint and one end 43 of rod 40 is bent at right angles to serve as a handle for turning the rod. Fixedly carried by rod 48 between the track rails are spaced cams 44 and 45, positioned respectively below the' paths of travel of coupler fianges 31 and 3,7 so that when turned to their full line positions in Fig. 7 they occupy said paths of travel. A leaf spring 45, one end of which is secured by rivets 4l' to the track supporting sleeper 48 bears at its free end on a square detent block 49 which is fixed onrod 4B outside the track rail and in a manner operatively to detain rod 48, its handle 4t, and cams 44, 45 either in their full line positions or broken line positions in Fig. 7 while yielding to permit manual shifting of these parts between their said positions as desired.
In operation the draw bars i8 and I6 extend parallel with the track rails 4l when the trucks l2 and i3 are on a straight stretch of track, but when rounding -a curved portion of track the trucks assume relative positions which may bring vthe draw bars into their relationship shown in Fig. 2. `Accordingly the catch studs 24 and 24 will depart from parallel relationship and this is permitted because of the play or lost motion permitted to the catch studs lengthwise of the notches 34' and 34 with which the studs cooperate to enable both hooks 33 and 33 to act as draft members. When the cars are rounding a curve as shown in Fig. 2 the hook head 33 and the catch stud 24 will alone act as the impelling elements of the coupling because the hook head 33 and the catch stud 24 are then so positioned that the catch stud yis spaced from the pulling edge of its hook head. This has the advantage of causing the coupling to drag one car after the other by means of a pull which is exerted upon the truck at a point of application and in a direction tending to swerve the truck in the direction it should swing to follow the curvature of the track and thereby reduces the tendency of trucks to jump the track when one car is pulling another around va curve at high speed.
For manual uncoupling, the body portions 36 and 3S or the flanges 3T and 31 may easily be reached by the fingers and simultaneously manipulated to lift the couplers 28 and 28 to their respective broken line positions in Fig. 1. In the automatic uncoupling, making use of the tripping apparatus of Figs. 7, 8 and 9, the handle 43 is swung to its full line position in Fig. 'I which swings the trip cams 44 and 45 into their upright full line positions in Figs. '7 and 9. In Fig. 7 the couplers 28 and 28 are riding toward the right carried by draw bars extending from the car trucks as indicated in Fig. 1. The hook head 33 of coupler 28 and the tail 32 of coupler 28' first pass over the tripping station after which the coupler flanges 3l and 3l' ride into contact respectively with trip cams 45 and 44 which cause both couplers to be lifted simultaneously so that the coupler heads 33 and 33 release the catch studs 35' and 35 respectively. In other words, by passing over these trip cams the couplers are swung upwardly to theirf broken line position in Fig. l thereby automatically todisconnect the cars it! and `l i. The width of flanges 31 and 3l makes uns action possible whether the tripping station at which rod 48 is mounted in the rails is on a curved stretch of track causing the-flanges to be related as in Fig. 2 or is on a straight stretch of track with the anges related as in. Fig. 8. The constraining eiect of spring 46 in bearing downwardly upon the detent block 49 holds the tripping cams 44 and 45 upright and undisturbed by the lforce of iianges 3l' and S'rubbing against them. Y A
Upon the approach of two cars whose trucks are equipped with the coupling devices heretofore described, the inclined edge 50 Yor 50 of each hook head of each coupler will cam over the catch stud upon which the other coupler is piV-.n
oted and thereby automatically interlock by re- 24diet assuming the coupled positions of parts shown in Fiss.. "1V and 7. t n The novel principles of coupling construction and action underlying these improvements as embodied in the devices herein disclosed are susceptible of embodiment in a variety of different forms all of which are intended to be included within the meaning of the following claims insofar as they fairly fall within the terms in which the invention is dei-ined therein.
