Application February 9, 1945, ‘Serial No. ‘577,055 ' 2 Claims. (El. 213-490) 1 2 This invention relates to coupling means which is especially, but not necessarily, adapted for use Figure 8 is a rear end elevational view of the fe male coupling head. in coupling mine cars or equivalent conveyances. Figure 9 is a perspective view of the special In carrying out the principles of the invention I have evolved and produced novel coupling means which, it is believed, is possessed of requi~ latch. ' Referring now to the drawings by distinguish ing reference numerals, it will be seen that the site factors of strength, durability and freedom‘ from liability, to derangement of parts. Secondly, I provide a coupler assemblage in which the female coupling head or unit is pro vided with a' simple and practicable cam-type latch, the latter being remote controlled by a rock , female drawhead or coupling proper is denoted by the numeral NJ. It is characterized by a sec tor-shaped shell having its ?aring end formed. ll. er shaft and a connection between same and said into a suitable mouth de?ned by a beveled lip II and cam-surfaced, opposed side walls [2.‘ This shell is bolted, or otherwise secured, as at iii, to a suitable base, for instance, a shelf-like exten latch, whereby to provide an assemblage of parts sion M on the body E5 of the car or other con which lends itself adaptable for coaction there C1 veyance or vehicle. The top wall thereof (see with of a companion male coupling head'having Fig. 5) is provided with a latch entrance and a simple free link which is virtually self-locating clearance slot l5 and at one end of the slot with and quickly and reliably engageable with said upstanding lugs ll’.

The rocker shaft is provided with lateral ends 32 which serve as handles. There is also a U shaped ?xture 33 bolted, or otherwise secured, to 40 the support, and this underlies the arm 29 and constitutes a suitable stop and rest therefor. The latch rocks toward its pivot means and trav els in and out through the slot H6 in the coupling head. It is normally closed, as shown in Figure 5, but is susceptible of being raised to releasing position, as shown in Figure 7. This is accom plished through the medium of the rocker shaft, handles, rocker arm and pull chain connection shown and described. elevation.

The link is anchored by a bolt, pin, 2,413,801 3 4 portion of said latch, said bar extending at its opposite ends beyond adjacent surfaces of said coupling head, coiled springs connected to the extending ends of said bar, and means anchoring the springs on said coupling head. or the like, 36. It protrudes through the open mouth and is in readiness to slip into the coupling head l0. When the coupling heads are brought together, the link unseats the latch by cam action, whereupon the latch is re-seated by the springs, thus e?ectively coupling the link to said head Ill. The release of the link is effected by disengaging the latch, as brought out advantageously in Fig 2.
