CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 434,757, dated August 19, 1890.

Application filed May 7, 1890. Serial No. 350,928. (No model.)

' which consists of the details of construction hereinafter more fully described, and illustrated in the drawings, in which Figure 1 is a side elevation showing two draw-heads with a link engaged in one and about to enter the other, the latter being shown in section. Fig.2 is a plan view of one of the draw-bars. Fig. 3 is a cross-section of a draw-head through the block therein. Fig. at is a perspective detail of the lower half of the draw-head, showing one of the members of the draw-bar in position. Fig. 5 is a perspective view of the link.

A designates the car-body, having the transverse bars B, and B is the draw-bar, comprising three members, having the squared heads H and shanks 71, adapted to fit into correspondingly-shaped recesses or notches N in the two halves of the draw-head D. In rear of the shanks h "the bodies of the members of the draw-bar B are preferably round, as shown at G, and transverse aligned openings g are formed therein for the reception of a rod R in rear of a Washer-plate W, as shown in Fig. 2, whereby the draw-bar is held in the transverse bars B of the car-body. Around the round shanks G, between the rear end of the draw-head D and therearmost of the transverse bars B, are located strong coiled springs S, forming a bumper or butter, as is usual in car-couplings.

The draw-head D is divided longitudinally and horizontally at about its center, whereby it is formed in upper and lower halves, these halves being connected by vertical bolts 0,

as shown. The mouth 0 of the draw-head may or may not be divided by horizontal webs, as shown; but if such webs are used their free ends are beveled or inclined, as is also the lower edge of said mouth. This incline is obviously for the purpose of guiding the approaching link into the mouth in a manner which will be explained hereinafter.

The pin P passes vertically through a hole'in,

grooves V, extending longitudinally of the draw-head, and terminating slightly in rear of said webs if they are employed. A pinsupporting block E slides within the drawhead and has lateral tongues c loosely engaging said grooves V. An operating-handle 1; extends from the upper end of this block through a slot K in the upper member of the draw-head to within easy reach of an operator; but if preferred the block E maybe pressed normally forward by a spring. (Not shown.) The front face of this block is provided with apertures k, approximating the shape of the end of the link, which will presently be described.

The linkL which I prefer to use is preferably of iron and is tapered both vertically and horizontally and slightly flattened at its ends, as shown at Z, and when this link approaches the open mouth of one of the drawheads it is guided thereinto by the inclines above mentioned.

The two cars approaching each other with the link seated in one draw-head, the block E in the other draw-head forward, and the pin P thereof supported at its lower end on said block, when the free end of the link enters the mouth of the draw-head, it passes into one of the apertures in the front of the block and pushes the latter rearwardly from beneath the pin, the pin falling through the link, as is common in devices of this character.

The advantage in having the draw-head formed in two halves detachably connected to each other, and also detachably connected to the draw-bar, is that when it is desired to gain access to the interior of the drawhead, as for the purpose of repairing or replacing the pin-support, two members of such drawhead may be disconnected and may be re moved from the draw-bar, the latter being first removed from the rearmost transverse bar B. It will be understood from the drawings that the body of the draw-head slides in the outermost transverse bar B, and hence the removal of the same outwardly therefrom is necessary before its two halves can be separated vertically.

What I claim is- 1. In a car-coupling, the combination,with a draw-head divided on a central horizontal line and having longitudinal recesses at the opposite sides of its opening, of bolts retaining the members of the draw-head in connected position, a longitudinally-sliding pinsupporting block within said opening, and lateral tongues on said block engaging said openings, substantially as and for the purpose set forth.

2. The combination, with a draw-head divided on a central horizontal line, the two members thereof having registering recesses with enlarged inner ends, of means, substantially as described, for holding said members in connected position, a transverse bar on the car-body, a draw-bar comprising a plurality of members fitting said recesses and having heads engaging the enlarged inner ends thereof, said members passing loosely through said transverse bar, a pin passingthrough the rear ends of said members, and springs around their bodies between the rear end of the drawhead and the front side of said bar, substantially as and for the purpose set forth.

3. The combination, with a draw-head divided on the the central horizontal line, the two members thereof having registering recesses with enlarged inner ends, a draw-bar comprisinga plurality of members fitting said recesses and having heads engaging the enlarged inner ends thereof, and a pin passing through the rear ends of said members, of transverse bars on the car-body, through the forward one of which the draw-head slides loosely and through the rear one of which the members of the draw-bar slide loosely, bolts retaining the members of the draw-head in connected position, and springs around the members of the draw-bar between the rear end of the draw-head and the front face of the rearmost transverse bar, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.
