TOY TRAIN COUPLER Filed March 22, 1944 BY way/Mm Patented Nov. 19, 1946 UNITED STATES PATENT OFFICE TOY TRAIN COUPLER Lawrence H. Strayer, Kent, Ohio Application March 22, 1944, Serial No. 527,601

9 Claims.

This invention relates to improvements in couplers for connecting cars on other units into a train, and has particular reference to an improved coupler for connecting the cars of a toy train.

Objects of the invention are to provide a coupler of the character above indicated which can be manufactured at a low cost; which will be strong and durable; which will be automatic in operation when used with a like coupler, and which is provided with means automatically operable to couple or uncouple the cars, while the same are relatively in motion.

The above objects are accomplished and other obvious ends attained by the novel construction hereinafter described with reference to the particular embodiment thereof disclosed in the drawing, it being understood that the invention is not confined to the particular form shown and that changes and modifications may be made which come within the scope of the claims hereunto appended.

In the drawing:

Figure 1 is a top plan view, on an enlarged scale, of two identical toy train couplers constructed in accordance with the invention, the same being shown in a coupled'condition.

Figure 2 is a'simllar view showing one coupler in an uncoupled or open position.

Figure 3 is a front elevational View of the coupler at the left of Figure 1, or a rear elevationa-l view of the coupler at the right of Figure 1.

Figure 4 is an end elevational view. of the coupler, as seen from the inner or couplings ends of either of the couplers in Figure 1.

Figure 5 is a rear elevational view of the improved coupler at the left of Figure 1 or a front elevational view of the coupler at the right of Figure 1.

Figure 6 is a bottom plan view of the two coupler units shown in Figure 1, but with the couplers in open positions either for a coupling or an uncoupling operation.

Referring to the drawings, the invention will be best understood by means of a detailed description of the coupler unit shown at the left of Figure 1, like parts of the coupler unit at the right of Figure 1 being given like numerals. The numeral 6 denotes a drawbar which is provided intermediate the length thereof with a bore 1 for receiving a pin or bolt by which it may be pivotally attached, for example, to a car or other unit of a toy train to swing relatively thereof in a horizontal plane. A reduced rear end extension 6a of drawbar 6 is provided with a bore 8, spaced from bore 1, adapted to receive a spring device (not shown) for yieldably holding the drawbar in alignment with said center line of the car or train unit to which it is pivotally attached. An oppositely extending forward end portion 61) of the drawbar is substantially wider than the portion 6a and is provided with an apertured lug or flange 9 at one side of the longitudinal center line of the drawbar.

A fixed jaw II] on the forward end of drawbar portion [ibis arched laterally outwardly and inwardly substantially in the same horizontal plane as flange 9, the free end of said jaw terminating just short of the drawbar center line.

The free end of said fixed jaw It] is provided with a vertical bar I l forming a T head.

The numeral l2 denotes a relatively movable jaw having a base portion provided with a recess in which the flange 9 is received, a pin !3 being positioned through aligned bores in the base portion and flange 9 whereby the jaw i2 may swing substantially in the horizontal plane of fixed jaw Hi. The jaw I2 is provided with spaced parallel prongs which curve oppositely of fixed jaw II) in the closed position of the jaws (Figure 1)., the free ends of said prongs Ma and l2b terminating in closely spaced relation to or in contact with the bar II in said closed position.

The jaw I2 is provided with an integral lever I20, which is an extension of prongs i2a and MD and extends substantially in the samehorizontal plane as jaws Ill and 12. the closed position thereof the free ends of the prongs of the lever 12c extend at opposite top and bottom sides of fixed jaw Ill and project beyond the same, as shown in the drawing.

A rectangular lug 14 projects downwardly from the drawbar 6 at the forward end portion 61) thereof, and a latch l5 is pivotally connected to the rear end face of said lug by means of a pin it. The latch l5 has an arm l5a which extends beyond one lateral edge of the drawbar 5 and is provided with a forwardly projecting member |5e having an upwardly extending head I5 for engaging the lower lever 12d to retain it in the closed position thereof, against the yielding action of a suitable spring H. The head 15) has a downwardly inclined forward face which, when the lever We is swung to closed position, is engageable by the lower prong l2c yieldingly to urge latch 15 downwardly, and thereby releasably lock the jaw 12f in said closed When the jaw I2 is in 7 to open the jaws 2 and uncouple the units of the train.

The T-head ll of the fixed arm It! is provided with forwardly inclined cam face i Ea, Which may be engaged by a like cam face of another coupler unit to guide the respective fixed arms of the units toward proper coupling relation thereof.

In use the drawbar 6 is secured to the floor or chassis of a toy car, engine or other train unit, preferably by a pin or bolt (not shown), and a spring or other means may be secured to the part 6a yieldingly to hold the drawbar 6 in longitudinal alignment with the center line of the train. Any suitable means, such as a relatively fixed cam, may be employed to engage the lever I5g when the train is moved past it, thereby yieldingly to disengage the latch I5 and automatically open the jaw !2 while the train is in motion. With the jaws E2 of two coupler units thus opened, when the train cars or units are relatively moved'toward each other, the main body of the fixed jaw l of each coupler unit will be received between the spaced prongs l2a and I2!) of the other, and the respective bars l I will be moved to engage the levers I20 and thereby operate the jaws l2 to a closed position. With this movement latch l5 engages the lever prong l2d and securely locks the couplers in coupled relation, as shown in Figure 1.

While the improved coupler unit has been described in reference to a preferred position, it will be understood that the same may be operated in any position and that the terms upper, lower, lateral, etc., apply to the coupler wherever used when placed in the position shown.
