SPECIFICATION forming part of Letters Patent No. 610,865, dated September 13, 1898.. Application filed January 31, 1898. Serial No. 668,541. (No model.)
.To (LM whom t may concern.- Y
Beit known that I, WILLIAM LOUDEN, a citizen of the United Statearesiding at Fairfield, in the county of Jefferson and State of Iowa, have invented a newv and useful Improvement in Trip-Couplings, of which the following is a specification.
My invention relates to trip-couplings for use in hay-slings and kindred devices; and it consists of the features herein described, and particularly set forth in the claims.
In the accompanying drawings, Figure lis a horizontal section on the line l l of Fig. 2, the view being from the under side. Fig. 2 is a vertical section drawn on the longitudi# nal center of the coupling as indicated by line 2 2 of Fig. l. Figs. 3, 4, and 5 are vertical cross-sections of a'complete coupling, drawn at the points indicated by lines 3, 4, and 5, respectively, in Fig. 1.l
A represents the main casting ofthe coupling, one end of which is made forked and the other is iitted with an eye, while its body has a cavity for the incasement of the trip mechanism. One of the prongs B is made substantially straight, and the other is bent toward it, so as to form a hook or lug C.
D is a trip-plate having two eyes E for the attachment of a rope F and a central eye G for the attachment of a rope I-I. The opposite end of the trip-plate D has aloop I', which is adapted to catch over the hook C.
J is a slidable trip-bolt fitted in ,the cavity in the body ofthe casting A and is adapted to close the opening between the prong B and the hook C and hold the loop I in engagement with the hook. The rear end of the trip-bolt J is fitted with fingers M, around which coiled springs N are placed. The ends of the fingers M are adapted to enter and slide in openings O, which are formed by semicircular cavities in the casting A and in the guideplate l?, riveted thereto.
The coiled springs N, resting against the edges surrounding the openings O, will press the tr-ip-bolt J outwardly into the opening between the prong B and hook C, and will thus prevent the detachment of the loop I from the hook C. In the central part of the bolt J is an eye K, into which a cord L is secured, and the free end of the cord is passed over the rounded edges Q of the guide-plate P. Apull on the cord L will overcome the resistance of the springs N and withdraw the trip-boltJ from theopening between the prong B and hook C, and thus permit the release of the loop I.
To lock the coupling, press the end of the loop I against the bolt J until it is pushed back horizontally far enough to let the loop catch over the hook C, when, if the cord L is free, the springs N will push the trip-bolt J out horizontally into its normal position and close the opening between the prong B and hook C. The ends of the hook C and bolt J are beveled to facilitate this operation.
To more securely hold lthe trip-bolt J in position inwardlyf'extending lips R are formed on the lower edges of the main casting A near the Vcentral or forward part of the bolt J, ori in place of two lips R, as shown in drawings, one on the lower edge of the prong B will suffice, so as to hold the head of the bolt J in place and let it slide freely in and out. It is also preferable to have two fingers M, each encircled with coiled springs N, so that if one should fail the other will remain; but, if desired, one finger only may be used and any other suitable kind of spring may be substituted.
Eyes S are formed on the sides of the main casting A for the attachment of a rope T. These eyes are set below the center of the casting A, so the rope T may be passed down through them and under the coupling between them, and the ends of the rope will draw in line with the horizontal center of the coupling. An eye U is also formed on the rear end of the main casting A and is set so that the rope V may be passed into it from the under side and knotted above and will draw on the line of the horizontal and longitudinal centers of the coupling. By setting the eye lU above the center instead of below ample room is provided for the passage of the trip-cord L.
The end of the trip-plate D stands in a vertical position and at right angles to the hook C, with which it connects. The other end of the trip-plate is disposed horizontally and contains the eyes E, through which the rope F is horizontally passed. The eye Gr is dis- IOO posed vertically and the rope II is looped through it. This arrangement secures a complete center draft of the ropes on the tripplate D.
It will be further observed that all the ropes will draw in line with the horizontal center of the coupling, and the connecting-loop I and hook C being free to accommodate themselves to any lateral strain the coupling will not be liable to become cramped in operation. This construction also permits the trip-plate to be made very light and yet have great strength.
The eye G is set so one edge of the wall surrounding it will bear against the rope F between the .eyes E and will thus prevent it from slipping. It is preferable to have the ropes F and T in one piece each and to have them passed through from one side to the other of the coupling; but each rope may be of two pieces, and each piece passed into its respective eyes, as shown, and then be knotted or otherwise secured, so it will draw true on the horizontal line of the coupling, as before stated.
If only two ropes at each end are required, the center ropes may be dispensed with, or, if only one rope at each end should be needed, the side ropes may be taken off and the center ropes left on, and under all these conditions the draft will always remain true on the longitudinal centers of the coupling, both horizontally and vertically. If desired, a pory tion of the prongB may be cut off so the tripbolt J Will project out beyond it; but in this case the bolt J would be more exposed and would have to be made stronger to stand the strain of the loop I upon it.
By making the guide-plate P separate and afterward securing it to the main casting A it can be more easily made smooth for the passage of the trip-cord, and the trip-bolt J can be first placed in position behind the lips R, and the plate then be secured to the main casting, so as to permanently hold the bolt J in place.
