This invention relates to car couplers, and has particular reference to an improved coupler for connecting. thecars and locornotives of toy railway trains. An object of the invention is to provide a coupler which is adapted for connection with a duplicate coupler, thereby to avoid the necessity of providing so-called. male and female, structurally different couplers, at the opposite ends of a car or locomotive, as has heretofore beencommon practice, and to avoid the objection of turning cars or locomotives end for end when forming. a my train, as is frequently required when the cars or locomotives are provided with so-called male'and' female couplers. 7

Another object of the invention is to provide a coupler embodying a construction affording positive connection with a duplicate muplernnder all conditions of move ment of a toy train, and which is yieldable topermit relative lateral movement of the ends of adjacent cars as in rounding curves inthe track and under similar conditions.

Another object of the invention is .to provide acoupler which will automaticallyconnect with a duplicate. coupler by relative movement of the couplers towardsv one another, and which may readily be uncoupled without removing the car or locomotive from thetrack. a 1

Another object ofthe invention is to pro-, vide a coupler which is adapted-tor connection not only with couplings which areduplicates thereof, but which also. is adaptedfor connection with other wellknown structural: ly different types of'oouplers. I 1

A in her object of the invention is to pm. vide'acoupling having the characteristics mentioned which is relatively cheap and easy to produce, which strong and durable, and which is thoroughlyreliableiand .eflicient in use.

With the foregoing and other objects in view, the invention consists in the novel features of oomdsruction, combination and arrangement of parts as will be hereinafter more fully" described, illustrated in the accompanyingdrawingsand definedin the appendedclamis. r

In the drawings, wherein like charactersof reference denote corresponding parts in the different views Figure 1 is a plan view of a pair of couplers embodying the novel features of the present invention, the couplers being shown in separated relation. 3 Y

. Figure 6 is a plan view illustrating the adaptability of the present couplerfor con nection with one well known structurally differentcoupler. 7

Referring to the drawings in detail, it will be observed that the present coupler is composed of only, two main Parts viz, a shank Aand alatch B andthat these, are of a design adapting them to be produced: economir cally in the form of; sheet metal stampings.

The shank A, which preferably is in the form of a sheet metal strip of suitable length, width and thickness, is inclusive of innerand outer end portions 10 and 11, respectively, which are laterally olfset with respect to one another, whereby the inner'end portion 10 is adapted to be mounted atthe transverse center of a car or locomotive and the outer end portion'll is adapted to overlap the outer end portion llofa duplicate coupler whenthercspective couplers are disposed in longitudinal alinement with their related cars or locomotives. Preferably, butwnol' necessarily, the outer .end portion 11 also is offset downwardly with respect to the inner end portion 10 to'dispose the connection between a pair of the couplers at a desired elevation. i

At its inner end, the portion 10- oi': the shank A is provided withan aperture 12 to receive apin or rivet 13 for pivotally con necting the coupler to a car or locomotive thereby to provide for lateral swinging movement of the coupler. v

The latch B is somewhat elongated and of inverted U-shape in cross section, being inclusive of a pair of side walls 15, 15 and a top wall 16. This latch is pivoted at its innerend on a pin 17 which passes through the ears 14-, 14 and through the side walls 15, 15, whereby the outer end 'ofthe latch is adapted to be raised and lowered, its normal position being horizontal and resting upon the outer end portion 11 of the shank A as is manifest. At its rear end, the latch B preferably is provided with an upwardly directed tongue 18 for finger engagement to effect pivotal movement of the latch in a directionto elevate its outer end, as. when effecting disconnection of a pair of the couplers, while intermediate its ends,.said latch has its top wall 16 cut away, as at 19, to provide an opening for the upward projection through said wall of a cooperating part of a companion coupler, and also to provide a strap or yoke element 20, which is part of the top wall 16, connecting the side walls 15, 15 between said opening and the outer or free end of the latch.

Formed preferably as an integral part of the inner car 14 and extending forwardly from the forward edge of said ear, is an arm 21 which is laterally offset, as at 22, to adapt its free or outer end portion to aline with the latch B of a companion coupler, and which terminates at its free or outer end in an upwardly directed extension 23 providing a rearwardly facing shoulder 24' for cooperation with the inner edge of the yoke or strap portion 20 of the latch of a companion coupler. From the top of said shoulder the edge of said extension 23 is sloped downwardly and" forwardly to the forward or free end of the arm 21, as at 25,

and from said free end, the lower edge of said arm is'sloped downwardly and rearwardly as at 26.

In view of the foregoing it is believed that the operation of the present coupling will be apparent as follows: As a pair of the couplings are moved relatively towards one another with the arms 21 alined respectively, with the latches B, the inclined lower edges 26 of said arms first engage-with the downwardly curved outer or free end portions 27 of the shanks A whereby said arms are directed over the tops of said shanks, and as the relative inward movement of the couplings is continued, the ends of the arms 21' enter the outer-ends of the latches B until the-inclined upper ed es 25 of said arms engage the strap or yoke portions 20of said latches and lift the outer endsof said latches. Then, asfurther relative inward movement of the couplings continues, the extensions 23.

of the arms 21 ride beneath the yoke or strap portions of the latches until the shoulders 24 of said extensions pass the inner edges of said yoke or strap portions 20, whereupon the latches gravitate to their normal position .tive inward movement of the couplings, since manifestly relative outward movement of the couplings cannot take place due to the abutting relation of the shoulders 24: with the inner edges of the yokes 20. However, to disconnect the couplings, all that is necessary is to effect upward swinging movement of the latches B, either by means of the tongues 18 or in any other suitable manner, to effect elevation of the inner edges of the yokes or straps 20. above the upper ends of the extensions23, whereupon the couplings may be moved relatively outward or separated as is obvious.

When a pair of the present couplinges are operatively connected with one another as illustrated in Figs. 3 andt of the drawings, the latches B manifestly provide means positively preventing any accidental disconnection of the couplings, and as is also manifest, the present coupling not only is adapted for connection with a duplicate coupling, but when a pair of the present couplings are connected with one another provision for ample relative lateral movement of the couplings is afforded by reason of the narrow width of the arms 21 as compared with the relatively wide space between the sidewalls ofthe yoke B.

To adapt the present coupler for connection with other well known structurally different types of couplers, the free end of the shank A preferably is provided with an outwardly directed lateral extension 28 having a slot 29 therein to receive the downward extension 30 or equivalent formation of well known types of other couplings as illustrated, for example, in Fig. 6 of the drawings.

Without further description it is thought that the features and-advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction maybe resorted to, without departing from the spirit of the invention and scope of the appended claims.

I-claim:

1. A car coupler comprising a shank, a pair of cars extending upwardly from opposite sides .of said shank, an arm extending forwardly from one'of said ears, said arm having an upward extension providing a hook, a latch pivoted between said ears and provided with an abutment for cooperation with the hook of another coupler to connect the couplers together, and means for holding the latch normally in an operative position for automatic connection with the hook of an 7 arm of another coupler when the couplers are moved together, said arm and said hook being laterally spaced from each other.

2. A car coupler comprising a shank, a pair of ears extending upwardly from opposite sides of said shank, an arm extending forwardly from one of said ears, an upward extension on said arm providing a hook, and a' latch of inverted U-shaped cross section ivoted between said ears with its lower e ges resting normally on said shank whereby it is held normally in an operative position, said latch having an o ening in the top thereof to receive the hoo of another coupler.
