Janney has secureda patent on an improvement in car-couplers, which is particularly ap-plicable to couplers of the Janney a coupler head, a pivotedknuckle and a locking member. Theinvention- consists of a change in thehead of the pin, as she .vn in the ac-companying illustrations, and preventsthe pin from turning round with theknuckle when the latter is swung toopen and closed positions. There arca number of reasons that experiencereadily demonstrates that the turningof the pin should be avoided, amivarious devices have been used withsuccess as long as the specially de-signed pin was used for the particularcoupler, but as pins often becomebroken or lost, unless a similar pin wasat hand the coupler and car were con-sequently placed out of DETAILS OF IMPROVED CAR-COUPLER. It will be noted that Mr. Janneys de-vice takes the form of a D-head pin,for the reception of which the coupleris furnished with an upstanding flangeor rib which is adapted to co-operatewith the head of the pin to completelyprevent the pin from turning, and atthe same time the flange or rib is farenough removed from the longitudinalaxis of the pin to permit the insertionof an ordinary round-headed pin suchas are generally carried in the equip-ment of trains. A round-headed pinof course will not be prevented fromturning, but will temporarily suit thepurpose until the proper type of pincan be procured. It may be added that it has been thecustom heretofore to provide a D-headpin by tangentially shearing off a por-tion of the head of the ordinary round-headed pin, so that the straight portionof the head was parallel with the outeredge of the pin. and any p
