PHILLIP DANIEL SERRURIER, OF SAVANNA, ILLINOIS, ASSIGNOR OF ONE-HALF TO HANS THOMSON, OF SAVANNA, ILLINOIS.

CAR-COUPLING.

Specification of Letters Patent.

Patented July 10, 1906.

Application filed March 27,1906. Serial No. 308,232.

Be it'known that I, PHILLIP DANIEL SER- RURIER, a citizen of the United States, and a resident of Savanna, in the county of Carroll and State of Illinois, have invented certain new and useful Improvements in OarCouplings, of which the following is a specification.

My invention is an improvement in carcouplings, and has for an object, among others, to avoid the objections resulting from the breaking of the coupling when in use and the invention consists in certain novel constructions and combinations of parts hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a coupling embodying my invention. Fig. 2 is a horizontal longitudinal section thereof. Fig. 3 is a detail rear elevation of the removable draft section. Fig. 4 is a front elevation of the coupling, the draft-section being turned ninety degrees from position for use. Fig. 5 is a perspective view of the coupling with the removable draft-sec tion turned to the position it occupies in inserting it in and removing it from the drawbar preliminary to turning it to or from the position shown in Figs. 1 and 2. Fig. 6 is a detail vertical section on about the line 6 6 of Fig. 2. Fig. 7 isa detail perspective view of a portion of the draft-section. Fig. 8 is a detail perspective view of the knuckle.

The purpose of my invention is to overcome the delays to trains caused by the breaking of the draft devices. It has beenfound that in most cases the part which breaks is the lug holding and forming a pivotal support for the knuckle. I have so constructed my coupling that when the lug is broken it may be removed and a new one applied without disturbing the draw-head proper. To this end I make my coupling in two sections A and B, and for convenience of reference I term the section A the draw-bar and the section B the removable draft-section, the latter being so fitted to the draw-bar that it can be readily removed therefrom when it is desired to replace it with another.

In the construction shown the draw-bar A has the draft iron or shank A and at the front end thereof the wings C and D, arranged at its opposite sides and diverging, as shown in Figs. 1, 2, and 5, and provided in their inner faces with vertical grooves C, D, and D The outer walls of said grooves are preferably curved concentrically 011 an arc struck from the center midway between the basewalls of the grooves C and D, so the ribs on the head of the removable draft-section may be moved into and out of said grooves as the said draft-section is oscillated or given a quarter-turn in the operation of applying and removing said section, as will be more fully described hereinafter. This is an important feature of my invention-that is to say, the rocking or oscillating of the head of the draftsection into and out of interlocking engagement with the head of the draw-bar-and I preferably secure this result by the construction shown and which will be more fully described hereinafter.

The draft iron or shank A has a longitudinal bore extending through the front of the head, and this bore has its front end elongated vertically and is provided in rear of said vertically-elongated entrance portion a with a recess a, elongated horizontally or in a direction out of alinement with the elon gated entrance portion, whereby the lateral wings b on the rearwardly-projecting rod B of the section B may be inserted through the elongated entrance portion a and then turned to interlock with the front walls of the recess a, as will be understood from Figs. 2, 6, and 7 of the drawings. 1) cooperates with ribs on the head B of the section B in securing the said section in connection with the section A, and means are provided for preventing the accidental turning of the section B from the position shown in Fig. 1 to that shown in Figs. 4 and 5, and these include a tapered pin E, passing down through the head A of the section A and through the rod B, as shown in Fig. 2. This pin E may be secured at its lower end by any suitable form of split key.

The section B has the head B provided with a forwardly-projecting lug b to which the knuckle F'is pivoted at F, and this head B is provided with the laterally-projecting ribs G, H, and I, which operate, respectively, in the grooves C, D, and D as will be understood from Figs. 1 and 5 of the drawings, and fit securely in the said grooves when the draft-section is pushed back to its rearmost position and turned from the position shown in Fig. 4 to that shown in Figs. 1 and 2 of the drawings, such position being also indicated in dotted lines in Fig. 4 of the drawings.

This winged construction When the head B is adjusted to the position shown in Figs. 1 and 2, it is locked in such position by the bolts J and K, (see Fig. 2,) extending through suitable openings in the head B and the head A and secured at their rear ends by any suitable form of split keys, as shown in Fig. 1 of the drawings.

These bolts J and K supplement the bolt E in preventing any accidental oscillation or turning of the head B from the position for use, as shown in Fig. 2, and thus preventing any accidental detachment of said parts and may be readily removed when it is desired to remove the head B from the body ofthe drawhead for any purpose. I

As will be understood from Fig. 8, the knuckle F has its rearwardly projecting tongue F constructed to cooperate with the locking-pin K, which latter may be connected to any suitable form of pin-lifter and is so constructed that it will remain in elevated position and will be caused to drop when the knuckle is closed, so it will lock the knuckle automatically in the coupled position. (Shown in Figs. 1 and 2 of the drawings.) This locking-pin K may be secured at its lower end by any suitable form of split key, so it cannot be entirely withdrawn from the head 13 of the draft-section.

I claim 1. A car-coupling comprising a bodyportion having a head provided with the side wings grooved vertically in their inner faces and having a longitudinal bore extending rearwardly from said head and having a transversely-elongated front portion and a recess in the rear thereof and elongated out of alinement with the elongation of the front entrance portion, a draft-section having a head provided at its opposite sides with ribs and adapted to be oscillated to adjust said ribs into and out of the grooves in the wings aforesaid, the said head being provided with a couplingknuckle and having a rearwardlyprojecting rod provided with lateral wings to cooperate with the entrance portion and recess of the bore of the body portion of the coupling, a bolt passing through the head of the body portion and the rod of the detach able section, and bolts. passing through the head of the detachable section and the head of the body portion whereby to prevent any accidental turning of the detachable section, substantially as set forth.

2. A car-coupling comprising a drawbar or body portion having a head, and a draftsection having a head rocking or oscillating on a horizontal axis into and out of interlocking engagement with the head of the body portion, said oscillating head being provided with coupling devices adapted to operate independently of said rocking or oscillating of the head.

3. The combination in a car-coupling of a body portion having the forwardly-projecting wings, a draft-section adapted to be fitted between said wings and rocking or oscillating on a horizontal axis into interlocking engagement therewith, and a rod secured to and projecting rearwardly from the head forming a horizontal axis for the rocking or oscillating of the head of the draft-section.

' 4. A car-coupling comprising a draw-head or bodysection, and a draft-section having coupling devices and arranged to be rocked or oscillated on a horizontal axis into and out of interlocking engagement with the head of the body portion, said draft-section and body portion being provided with cooperating up right ribs and grooves, substantially as set forth.

5. The combination in a car-coupling, of a draw-bar or body portion having a head provided with the forwardly-projecting wings at its opposite sides and having upright grooves in the inner faces of said wings, and a bore or opening extending rearwardly between said grooves, and a draft-section having a rod provided with a rib operating in said bore or opening, and lateral ribs to enter the upright grooves in the head of the body portion, and coupling devices carried by the head of the draft-section, substantially as set forth.

6. The combination of a body portion having a head and a central bore or opening leading rearwardly therefrom, and a draft-section having a head rocking or oscillating into and out of engagement with the head of the body portion, and a rod projecting rearwardly from the head of the draft-section and having lateral wings interlocking with shoulders within the central bore or opening of the body portion, substantially as set forth.

7. The combination of a draw-bar or body portion having a head and a removable draftsection having a head provided with coupling devices, and oscillating or rocking on a horizontal axis into and out of interlocking engagement with the head of the body portion, and bolts between the heads of the removable draftsection, and body portion or draw-bar whereby to prevent the accidental rocking of the draft-section head out of locked engagement with the head of the body portion or draw-bar.
