Claims. (Cl. 213--'20) The present invention relates to new and useful curved and provided with a horizontally extending improvements in couplings for mine cars and slotted opening l3 having flanges l4 secured at similar vehicles in which the respective sections the edge portions thereof and projecting through of the coupling may be automatically secured in the opening is the coupling stem l5 having the 5 position for coupling the cars together without cylindrical coupling head H5 at the outer end necessitating a person entering between the cars, thereof for insertion into and engagement by the as well as providing means for releasing the coufemale coupling member I. pling mechanism alongside of the cars and the The inner end of the stem I5 is reduced as primary object of the present invention is to proshown at I? and is slidably mounted in the bore vide apivoted coupling stem carriedby one of the i8 of a socket member [9 which is formed with 10 cars to enable the free turning movement of the upwardly and downwardly extending trunnions adjacent cars as the same are rounding a curve 20 and 2i respectively, journalled in openings in the track and also to provide means for mainformed in the upper and lower plates l0 and l I, taining the coupling stem in the desired position respectively, as shown in Figure 3 of the drawings.
for coupling cars positioned on a curve in the The socket member I9 is formed with forward- 15 track. ly eirtending spaced parallel arms 22 between A still further object is to provide a device of which the stem i5 is freely positioned, the stem this character of simple and practical construcbeing provided with a coiled spring 23 for yieldtion, which is efficient and reliable in perably projecting the stem outwardly, the stem beformance, relatively inexpensive to manufacture ing provided with upwardly and downwardly 20 and maintain in operation and otherwise well extending pins 24 and 25, respectively, adapted adapted for the purposes for which the same is to abut the inner edge of the flanges M to limit intended. outward movement of the stem. Also as shown to Other objects and adavantages reside in the deadvantage in Figure 4 of the drawings, the inner 25 tails of construction and operation as more fully edges of the flanges M are curved to facilitate the 25 hereinafter described and claimed, reference beriding of the pins 24 and 25 along said flanges ing had to the accompanying drawings forming during the swinging movement of the stem. The part hereof, wherein like numerals refer to like stem is normally maintained in a centrally disparts throughout, and in whichposed position in the slotted opening l3 by means Figure 1 is a top plan View of the adjacent ends of coiled springs 28 and 21 attached to the arms 30 of a pair of cars in position the same would 00- 22 and 23, respectively, one end of each of said cupy relative to each other when on a curved springs being anchored to an adjacent side of track, the housing 8.
