cAR-coUPLlNG.
SPECIFICATION forming part of Letters Patent No. 487,924, dated December 13, 1892.
' Application iiled March 15, 1892. Serial No. 425,036. (No model.)
To a/ZZ whom t may concern.-
Be it known that I, WILLIAM N. HARING, of Nyack, in the county of Rockland and State of New York, have invented a new and useful Improvement in Car-Couplings, of which the l following is a speciication.
My invention relates to an improvement in car-couplings in which provision is made for the locking of the coupling-heads together either automatically or by hand and in which the heads may be released either by drawing upwardly directly upon the locking-pin or elevating it by an indirect attachment from the side.
A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a top plan view of one ot' the coupling-heads and the parts which support it. Fig. 2 is a horizontal section through the draw bar and head. Fig. 3 is a view of the same in side elevation, showing, also, one of` the side supports and a portion of the buffer; and Fig. 4. is a vertical transverse section through the coupling-head on line wx of Fig. l.
The supporting-beams between which the coupling is mounted are represented by A and A', and they are connected at or near -their front ends bya bader-beam a, (see Fig.
3,) to the front of which a buffer Bis securedin the present instance by means of bolts b, extending through the buer-beam. Between the said beams A and A there is iixed a heavy bracket O, the forward end of which is bifurcated to receive between its lugs c the head d ofthe plunger D. A heavy cross-bolt c extends through the lugs c and the head d of the plunger to secure it to the bracket O. The plunger rod or stem is denoted by d and it has mounted thereon the end washers d2' The plunger is locked Within the socket in the draw-bar E by means of keys e', which extend downwardly through the rear end of the draw-bar, upon opposite sides of the plunger, as clearly indicated in Figs. l and 2, and form abutments for the end washers d2, so that when the draw-bar Eispulled outwardly it will slide the washer d2 on the stem of the plunger, and thereby compress the springs d5 and d6. The limit vof the outward movement of the draw-bar is determined by the engagement of the shoulder e2 on the under side of the draw-bar with the fixed cross-bar a', bolted or otherwise secured to the under sides of the supports A and A. The draw-bar E is held in position between the supports by means of a cross-bolt c2, extending through the supports A and A and through an elongated slot e3 in the side of the bar. The washer d3 abuts against internal shoulders e4 within the drawbar, and when the draw-bar E is forced inwardly it carries the washer d3 with it, and thereby compresses the springs d5 and d6. The limit of the inward movement of the draw-bar is determined by the engagement of shoulders on the coupling-head with the front of the buffer B.
The body portion of the coupling-head or draw-head is represented by F, and it is provided with a hinged jaw f and a stationary jaw f', between which the hinged jaw of the opposite coupling-head is received when 'the two are brought together into interlocking adj ustment.` The head F has extended rearwardly therefrom a stem f2, (see Fig. 2,) adapted to seat within a socket e5, formed in the front end of the draw-bar-E, and is secured therein by means of a coupling-pin G, extending downwardly through the draw-bar and the stem f2, so that if from any cause the draw-head becomes useless it may be removed and an ordinary link-and-pin lattachment may be made directly with the front end of the draw-bar. The head F is provided with a socket f?, extending transversely therein, and in said socket there is seated a sliding bar II. The projection f4 on the swinging jaw f projects within the socket f3 and seats loosely within a recess h, formed in the front of the bar H, so that as the jaw f opens and roo closes on its pivot to release or lock the corresponding jaw on the opposite draw or coupling head it will slide the bar H inwardly or outwardly in the socket f3, and if the bar H be locked against an inward movement it will thereby lock the head F against swinging outwardly to release the corresponding jaw of the draw-head. A locking-pin g is seated within the head F so as to have a limited vertical movement therein and is adapted to drop downwardly through an opening h' in the bar H when the latter is at the limit of its outward movement, and thereby lock it againstinward movement until the pin g is withdrawn. The pin g has a guiding-prong gthereon,ex tending downwardly through the head F, and is iitted at the top to receive an operating chain or cord. The pin g may also be operated bymeans of an angle-lever pivotally secured to the head, as at I, one arm 1l of said lever extending within the head and loosely engaging within a recess g2 in the side of the pin g and the other arm i being fitted for the attachment thereto of an operating-chain K, leading to the side of the car. By pulling upwardly on the pin g by a cord or chain attached to its top and leading, for example, to the top of a freight-car the bar H may be released and the jaw f thereby allowed to swing outwardly and uncouple. By pulling outwardly on the chain K the. angle-lever, pivoted at I,will rock in a direction to lift the pin g, and thereby release the bar H and permit the jawf to swing and uncouple. As two opposite draw-heads come together the jaws f will be swung simultaneously inwardly, and the bar H will thereby be moved outwardly until the pin g drops under the influence of gravity through the bar H, and thereby locks the couplings together. In case the pin gshonld become broken or jammed, so that it could not be utilized to lock the bar H in its outward adjustment, I provide for locking it in such position by hand by forming a perforation h2 downwardly through it near its outer end for the purpose of receiving an ordinary coupling-pin. The free end of the jawfis bifurcated and provided with the perforation f5 therethrough to receive the ordinary link and coupling-pin, as is usual.
Nhat I claim isl. The draw-head comprising a body portion, a swinging jaw secured thereto, a coupling-pin, and a sliding bar having aloose connection with the swinging jaw and couplingpinto lock and release the jaw when the bar is locked or released by the pin, substantially as set forth.
2. The draw-head comprising a body portion, a swingingjaw secured thereto, a laterally-sliding bar having a loose connection with the swinging jaw, a locking-pin having a limited movement into and out of engagement with the sliding bar, and a lever having a loose engagement with the locking-pin for operating it and hence releasing the bar, substantially as set forth.
3. The combination, with the draw-barand draw-head secured thereto, of a plunger inserted within the rear end of the draw-bar, a bearing on the plunger, and keys extending downwardly through the draw-bar in engagement with the bearing forlocking the plunger therein in removable adjustment, substantially as set forth.
