SPECIFICATION forming part of Letters Patent No. 498,621, dated May 30, 1893.
Application filed January 11,1893. Serial No. 458,097. (No model.)
To all whom t may concern.- andthe other orhooked end e bearing against Be it known that we, FRANK H. CLARK, rethe coupling pin C. The form, dimensions siding at Saratoga Springs, Saratoga county, and material of the bell crank D andlever E and ROBERT C. TURNBULL, residing at Troy, may be altered as desired, so long as they are 5 Rensselaer county, New York, citizens of the capable of co-acting to produce the desired United States, have invented a certain new result. and useful Improvementin Car-Couplings, of The device operates as follows: It should which the following is a specification. l be understood that under normal conditions As is well known, the car couplings, inuse the bell crank lever, hook E, dac., remain in- 6o ro to-day are liable to be torn from the cars to operative. lf now, however, the coupler be which they are secured by accident or othertorn from the car, the chain will operate to wise, and, falling upon the track, to derail the draw the arm d of the bell crank toward the car. Some means is therefore desired which left (Fig. l). The arm d will then act to/de- Y shall act to prevent accidents of this characpress the end cof the pivoted hook lever, and I5 ter, and which shallpreferably operate to first raise the end e', thereby raising the locking uncouple the cars, and afterward to prevent pin and allowing the rotating hook to swing lthe detached coupler from falling upon the open to separate from the coupler with which track.- it is in engagement,after which the chain will It is the object of our invention to provide vact to sustain the coupler and prevent its 7oy zo a device of this character, and, stated generfalling upon the track. We thus provide ally, we accomplish this object by providing what may be called an emergency device the couplerwith suitable mechanism adapted, for uncoupling the coupler and preventing when the coupler is torn from the car, to enaccidents; and While we have described more gage with the locking pin to release the hook or less precise forms, we do not intend to 25 to unlock the coupler, and afterward to susunduly limit ourselves thereto, but contemt-ain such coupler and prevent its falling upon plate changes in form and proportion, and the track. the substitution of equivalent members as Our invention consists in the features, demaybe desirable or necessary. For example, tails and combinations hereinafter described itis not essential that the end of the locking 8o 3o and claimed. pin 'should extend below the draw head, as In the drawings, Figure l is a side elevathe form of the hookE may be so changed as tion of a coupler provided with our improveto engage with the locking pin, the only esments; and Fig. 2 a front elevation thereof. sential feature being that such engagement The coupler, so far as the draw head A, roshould exist as will permit the above described 35 tating hook B, and coupling pin C are conaction to take place.
cerned, may be made in any of the well known We claimstyles, which will enable the hereinafter de- 1. A coupler provided with two levers enscribed devices to act as set forth. We irst gaging each other one lever contacting with attach to one side of the coupler, which may the locking pin, and the other connected to a 9o 4o be either side desired, a bell crank lever D, point outside of the coupler, such levers bewhich is preferably so attached as to be capaing adapted to remain inoperative under norble of rocking in a substantially vertical. mal conditions, but acting in case the coupplane, with one armcZ extending upward, and ler is detached from the car to raise the pin, with the other d extending toward the car. release the hook, and prevent the coupler 45 The arm d is securely connected to the car D2 from falling upon the track. substantially as by means of a chain D', for the purpose heredescribed. inafter described. Ve then pivotally attach 2. In a coupler provided with a locking pin, to the draw head, at any suitable point, a lethe combination of a bell crank lever pivoted ver or hook E, preferably made in the form to the draw head, a chain attached to one arm Ico 5o shown, one end of this lever e being in enof such lever andto the car, and ahook lever gagement with the arm d of the bell crank, pivoted to the draw head, engaging with the other arm of the bell crank and with the coupling pin, substantially as described.
3. The combination with a draw head .provided with a rotating hook and a locking pin, of a bell crank lever pivoted at one side of the draw hcad, with the arms of the lever extending in substantially horizontal and vertical'positions, a chain attached to the car and to the vertical arm of the bell crank, a hooked lever pivoted beneath the draw head, one arm of such lever engaging with the horizontal arm of the bell crank and the other arm im pinging against the lower end of the locking pin, whereby when the coupler is' detached from the car, the chain will act on the Verti- 15 cal arm of the bell crank lever to rock the hook lever and raise the pin to release the rotating hook, thereby uneoupling the car, after which the chain will act to sustain the coupler and prevent its falling upon the track, zo substantially as described.
