(Cl. 213*405)‘ ‘ 1 My invention relates to toy trains and .has among its objects and advantages the provision of . , .. 2 . . one end lying in a notch‘ 50 in the head 22. This spring includes two arms, the arm .52 engaging one wall» of the slot'28 and the end 54 having a bend 56 engaging a concaved face 58v on the arm an improved car coupler designed to permit the coupler to be madein accordance with a prede termined scale, and-in‘which the couplers oper Cl “ 32. The tension of the spring 48 yieldingly urges ate ef?ciently, in addition to being interchange the arm 32 in a clockwise direction when viewed according to'Figures 1- and 2. ~ able with scale model couplers of other design. In operation, Figure 1 illustrates the coupler While scale model couplers have been employed members l2 engaged for car coupling purposes. in connection with toy trains, such couplers are not entirely dependable, 10 The flat faces 26 of the two jaws 24 lie in face to face engagement, this engagement being yield In the accompanying drawing: Figure 1 is a top plan view of a coupler in ac ingly maintained by reason of the pressure of the arms 32 on camming faces 60 on the respective cordance with my invention.

In the embodiment of the invention selected for illustration, Figure 1 illustrates a coupler l0 com ciently far to permit the hooks 24 to pass there between, with the camming surfaces 60 spreading the members 32 as the heads 22 are moved into coupling engagement. The tension of the springs 48 is suf?cient to hold the hooks 24 effectively in prising two identical coupler members l2. Since the members 12 are identical in construction, the 30 coupled engagement, and the faces 26 are of suf ficient extent to maintain such coupled engage description of one will apply to both and similar reference numerals are applied to both parts. ment. ‘ To uncouple the heads 22, either or both springs The member l2 includes a shank I4 provided 36 are pivoted in counterclockwise directions with a centering spring l6 coacting with suitable structure not shown, and which forms no part of 35 when viewing Figure 1.
