CAR-CCU PLINGJ SPEGEFICATION forming part of Letters Patent No. 567,465, dated September 8, 1896.
" Applieationfiled April 3, 1896. $erial No. 586,067. (No am.)
T0 on whom it may concern: V
Be it known that I, THOMAS GALLIGAN, of Bradford, in the county of Miami and State of Ohio, have invented new and useful In1- provements in Oar-Couplings, of which the following is a full, clear, and exact description.
This invention relates to car-couplings of the J anney type, in which a drawhead having a pivoted laterally-movable knuckle is provided.
The object of the invention is to provide a car-coupling of the indicated character with novel features of simple construction, which will render the improved coupling very effective in operation and adapt it for release from another coupling of similar construction in a safe manner from the side of the car having the improvements.
The invention consists in the construction and combination of parts, as is hereinafter described, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a reverse plan View of two main portions of two car-couplings having the in1- provements, and of a car-frame portion shown in dotted lines, one coupling being represented in place thereon. Fig. 2 is a detached and partly-sectional plan View of the main portion of the improved car-coupling. Fig. 3 is a front end view of the improved coupling. Fig. 4 is a detail View.
In carrying into efiect the features of invention, 10 indicates the novel draw-head, which is integral with the elongated draw-bar 11, the latter being in service secured to the frame A of a car by any preferred means". The draw-head 10 projects at one side of the draw-bar and is forwardly curved a suitable degree, having a convex outer side and a concave front produced thereon, which converge and afford a horn a. Thedraw-head is chambered, so as to provide a receptacle for the tailpiece 13 of the knuckle 12, and the upper and lower sides of said chamber 7) are rendered level and parallel, so that the tailpiece may freely rock therein, the chamber having an opening 0 at the front and side opposite fromthe horn a for the free introduction of' which is concentric with the'pivot-h ole formed.-
in the tailpiece for the reception of the pintlebolt 14, said hole being in alinem'ent with opposite perforations of equal diameter therewith, whichare produced at a correct point in the upper and lower walls of the draw-head chamber. There is a toe 13 formed integral with the tailpiece 13;, which toe projects therefrom, having suitable length and breadth to adapt it for effective service, and between the forward edge of the toe and a shoulder e, where the thicker knuckle-body 12 integrally joins the tailpiece,the peripheral portion. 9 of the latter is convexly curved, and its arc may be concentric with the convex-curved edge portion cl.
The kn uckle-body l2 and its integral latching-jaw 12? l are. preferably made equal in thicknesswith that of. the draw-head 10, and said parts are laterally curved to produce a hook-like formation, the jaw being rendered substantially ovate edgewise and curving slightly rearward when ina normal position,
so as to insure its latching engagement with a similarjaw on a mating car-coupling and maintain such a connection until designedly released. It will be seen that, the width provided for the knuckle-body 12 at its shoulder c being less than, the transverse diameter of the tailpiece 13, an opening for the limited rocking movement of the knucklebody is afforded at the rear edge of thelatter, where it joins the tailpiece. It'is essential that such a relative proportion be had with regard to the construction; of parts j list described as will permit a sufficient rocking movement of the knuckle-jaw 12 for its release from a coupled condition, as will be more fully explained. The knuckle-block 12 is furnished with a laterally-extending limb 12 which projects nearly opposite from the latching-jaw 12 and has an oblong orifice 2' formed in it, which extends across the limb, as indicated by dotted lines in Figs. 1 and 2.
Anarm lO is formed on the draw-head 10 V near its junction wit-h the draw-bar 11, said arm projecting at the same side of the coupling with the limb 12". On the outer end of the arm 10 there is a spring carrier-rod 15, pivoted by its rear end, as at 70, the free front end of said rod loosely passing into the orifice i of the limb 12".
The carrier-rod 15 is furnished with avcollar 'm, that is formed or secured thereon near the point of its pivotal connection with the arm 10. A strong spiral spring 16 is mounted on the carrier-rod 15, having such a length as will permit its ends to respectively press on the collar m and on the rearside of the V limb 12", thereby normally effecting a contact of the toe 13 with the rear wall of the draw-head chamber 1), as shown in Fig. 2,
which will .give to the latching-jaw 12 a correst position for a coupling engagement with a similarly-positioned jaw on a car-coupling of like construction.- On the outer end of the limb 12*. a link-bar 17 is pivoted, the other end of said link, thattrends toward the carframe A, having: a pivotalconnection with one endnof the lever .18. As shown in Fig.
1, the lever. 18 is laterally bent to adaptit for efficient service, and at a suitable distance fromthe pivoted connection 41, between the lever and linkba-r, the lever is pivotedon the car-frame A, as represented at 0. -A
sufficient lenglh is provided for the main portion ofthe lever 18 to extend its free end 18 near. tothe side of the car-frame, so that said end may be safelymanipulated as a handle byanoperatoralongside of the car. The portion ofthe lever. -18 thatis between the pivot o and free end 18 is preferably sup-- ported by thebracket-plate 19, that is in the form of a bent bar having its ends secured to the car-frame and so offsetted between these points of attachmentthat the long member of the lever Willbe adapted for vibration while resting on the bracket-plate.
'lhehracket-platelil is provided with a loopedprojection pron its lower side, that is I provision of the lever 18 and link 17 con-,-
venient: and reliable, means are afforded for the outward-and rocking movement of the knuckle 12, against the stress of the spring 16, to release two couplings that are on cars and) have coupled engagementwith each other,.so that a disconnection of two coupled cars maybe-safely and convenientlyeffected.
The. latching-jaw 12 is caused,-when in normal position, to project its nose one-half of the length ofsaid jaw across a straight line thatiextends longitudinally through the transversecenter ofthe draw-head 11,-so that the center of the draft strain applied to two coupled draw-heads on two of the improved car-couplings will be represented by a line 1 1, that crosses the centers of the pivot-bolts 14: and transverse centers of the latch-jaws 12 and draw-bars 11, as clearly shown in Fig. 1.
The manner of constructing the knuckle and chambered draw-head insures the release of the knuckle-block in case the pivot-bolt 14 should be detached or broken, and as the link 17 is still in connection with said knuckle it will be evident that the latter will be prevented from falling on theground, whereby it is saved from loss or from producing an accidental derailment of cars, that might occur if this part of the coupling should fall on one of the track-rails.
' It willbe evidentthat in the improved car? coupling there is no need toprovide means for locking the knuckle in closedadj ustment,
as the application of draft force totwo of said i couplings that are connected being central on the line 1 1 insures a maintenance of their ,a
coupled condition at all times until one or both of the knuckles are laterally swung on their pivot-bolts to uncouple the draw-heads. I It will be apparentthat the stress ofithe springs 16 holds the mating jaws 12 in position for an automatic coupling engagement when two of the improved car-couplings are brought together, the convex andrearwardlysloping faces of the front sides of their hooked members facilitating a latching connection of saidparts. The hook nose of the latchingjaw 12 is horizontally slotted at its center of thickness, as shown at r in Fig. 3, and said nose is also vertically perforated, as at s, for the reception of an ordinary coupling-pin, (not shown,)'so that a com mon coupling may -be connected by its elongated link with the improved car-coupling if the link is placed 1 in the slot 0" and-thensecured by a pin dropped into the perforations s. Having thus described my invention, I claim as-new and desire to secure by Letters Patent-- 1. The combination with a chambered-drawhead, and a pivoted knuckle having a hook like latching-jaw and a lateral projection op= positesaid jaw; of a rod pivoted to said drawhead and supporting a spring adapted to hold said jaw in'coupled engagement, the free end of said rod passing through saidprojection,
