SPECIFICATION forming part of Letters Patent No. 389,510, dated September 11,1888,

' Application filed May 4, 1888. Serial a... 272",177: no model fl To all whom it may concern:

Be it known that I, JAMES A. HINSON, a citizen of the United States, residing at Des Moines,in the county of Polk and State of Iowa, haveinvented certain new and useful Improvements in CarOouplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to carcouplers of that type known as twin jaws, in which jaws pivoted in the draw-bars interlock to couple the cars; audit has for its object to provide a very simple and durable coupler of but few which will automatically couple, and which may be uncoupled from the side of the car at the end almost instantly and with great ease; and it consists of the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specifieation,'Figure 1 is a perspective view of my improved coupler in position on the end of a car; Fig. 2, a vertical longitudinal section through the draw-bar; Fig. 3, a horizontal section on the line mm, Fig. 2; Fig. 4, a side view of the draw-bar; Fig. 5, alike view partly broken away to show the means for securing the movablejaw to the draw-bar; Fig. 6, a detail view showing a modified arrangement of the latch; Fig. 7, an end front perspective view ofthemovablejaw; Fig. 8, a perspective view of the movable jaw, looking toward its inner side; Fig. 9, a horizontal section on the line 3 y, Fig. 7; and Fig. 10', a detailview of the end of one of the arms and a block.

Similar letters refer to similar partsthroughout the several views.

A represents the draw-bar, which is made hollow, and so connected to the car as to have a limited longitudinal movement, its rear end being cushioned against a spring to dead'en the effects of concussion,'as is customary. At the front end of the draw-bar two flaring arms, B B, the latter being merely a guard-arm,are

. cast, between which is a recess, a, to receive the branch b of the movable jaw G, as will be explained hereinafter. A hollow offset, 0, is also cast integral with the draw-bar, which forms a shoulder to abut againstthe front beam,

D, of the car, as shown in Fig. 1, when the draw-bar is driven back. The arm B of the draw-bar is cast with flanges (1, having circular recesses e formed in their contiguous faces and slots f enterin g said recesses from the outer edges of said flanges, for a purpose which will be described hereinafter. On the inner face of the arm B, at a suitable distance from its end, a wedge-shaped recess or depression, g, is formed to receive the hook-shaped projection h on the branch b of the movable jaw 0 when the coupling is made. In the lower part of the draw-bar, immediately beneath the offset c, a recess, 70, is formed, in which the lower end of the latch E-is pivoted, as shown in Fig.

2, and a spring, F, having one end bearing against said latch, is adj ustably secured in the draw-bar in the rear of said latch. The upper end of the latch extends into the hollow offset 0, and is connected to one end ofa short chain,

Z, the other end'of said chain being attached to a pin, on, having a collar, a, and an eye, 0, cast thereon, said pin passing through an opening in the upper part of the offset 0 to make the connection. The collar it prevents the entrance of dirt in the offset. To the eye- 0 of the pin the crank-arm p of the rod 1' is at tached, said rod beingsnitabl y attached to the end of the car, so as to be easily turned by its handle .9 to lift the pin, and thus draw the latch backward against the spring and release the branch b of the movable jaw to uncouple.

The spring F will hold the latch normally in the positionshown in Fig. 2, and will throw it back into such position after the latch has been forced back by the branch I) in coupling or by the rod 1" in zuncoupling, so that the latch will be always in position to lock the. branch b in place.

In Fig. 6 I show the latch E provided with a shoulder, t, and pivoted at its upper end in the offset 0 and its lower end projecting through a slot, 14, formed in the bottom of the 9 5 draw-bar, and connected to a rod, 1), by means of a chain, 10, said rod '0 being suitably journaled to a hanger, w, extending from the car, so that upon turning the rod the latch will be drawn back to release the branch I) of the [O0 movablejaw, while a spiral spring, a, in the offset 0, and resting on the shoulder It, will throw the latch forward or into its'normal position again when the same is released. It

will be understood that both the rods 1' v are not to be used at the same time, although they are both shown in Fig. 1 to more clearly explain the means for operating the latch Ewhen pivoted above and below.

As shown best in Figs. 7, 8, and 9, the movable jaw O is formed with branches 1) and b, the former, when the jaw is in position on the draw-bar, extending back into the recess a in said draw-bar and having the projection or hook it on its outer face and its end 0 tapering oil, so that it will the more readily slip past the latch in coupling the ears. The branch I) is rounded or curves on its outer face, as shown at s in Fig. 7, to form a buffer, and has a slot or pocket, d, formed through the same to receive a link when one of the cars it is desired to couple together is not provided with my improved coupler, but only with the ordinary link, and an opening or perforation, c, is formed vertically through branch I) at right angles to the pocket d to receive a pin, t, to secure the link in position and complete the coupling. This pin rests on a shoulder, a, (shown in dotted lines in Fig. 2,) which is cast in the front side of opening 0, so that when the draw-heads come together in coupling the shockor concussion will jar the pin off of the shoulder and cause the same to drop into the opening 6 and through the link.

On the body of the jaw G, at thejunction of the branches 1) b, oblong journalsf are cast. As will be noticed, the branch I) is wider or longer than branch b, and the reduction of the latter leaves shoulders g at the ends of the branch 0, which are curved or hollowed out, so as to lit the rounded ends of the flanges d of arm B snugly, and the journals f are at right angles to said curved shoulders. The journals are adapted to fit the recesses 6, formed in the flanges (1, they being inserted endwise therein through the slotsf and the jaw given a short turn, so as to bring thejournals lengthwise across the inner ends of the slotsf, and thus prevent their accidental displacement. To guard more securely against any displacement, I form the curved grooves p in the jaw immediately opposite the journalsf and fit a perforated block, 11., having a shoulder, at, into the slotf, and there secure it by a screw or bolt entering its perforation through a perforation formed in thejaw, while its shoulder at enters the groove p and serves to limit the swinging movement of the jaw.

Thus it will be seen that the strain in drawi ng the cars is borne by the latch and hook it, and that I provide a very strong coupler, there being but three pieces practically forming the same, and that the means employed to effect the journaling of the jaw to the draw-head forms a very secure and strong attachment which is not liable to break or get out of repair.

Having thus described my invention,whatI claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a car-coupler, of the draw-bar having the hollow offset 0, the arms B B, the former having the flanges d cast integral therewith, the recesses 0, formed in said flanges, the slots entering said recesses, the rnovablejaw 0, having the branches I) b, the oblong journals cast with said jaw, the pivoted latch,and means for operating said latch, sub stantially as described.

2. The combination, in a car-coupler, of the hollow draw-bar having the offset a and arms B B cast therewith, the latch E, pivoted in said draw-bar, the spring bearing against said latch, the chain connected to said latch, arod connected to said chain, and the movable jaw pivoted to said arm B and having the branches bb', one of said branches being adapted to swing against the latch, substantially as described.
