My invention relates to automatic trainpipe connecter heads Among the objects is to provide a coupling head of the pin and funnel type in which the gathering range may be substantir ally varied without destroying interchange with previous heads of the same type. This advantage is attained by placing the usual fluid conduit in the head, and by disposing the coupling face of the head obliquely to the longitudinal direction of the connecter, and with the face of the conduit, and the coupling face, of the head, in the plane of one wall of the funnel. The construction is simple, compact, and very effective. In the drawings I f Figure l is a sectional plan view of a pair of my improved coupling heads in the coupled position. One of the heads has a substantially greater gathering range than the other.

Figure 2 is a side elevation of the construc-- tions shown in Fig Figure 3 is a front view of the coupling head having the increased gathering range A hereinafter described. In this view the fitting 9 is omitted, and

Figure 4 is a detail of the plunger pin 12.

My improved coupling head 5 may be supported from the car coupler by any desired form of support 6. The head consists of a funnel 7 on one side of the longitudinal centre line of the connecter and in the rear of the vertical centre of the coupling face of the head, and a forwardly extending prong or pin 8 on the opposite side of the longitudinal center line of the connecter, and in advance of the vertical centre of the coupling face of the head. As appears particularly in Figure 1, the conduit 9 passes through the head obliquely to the longitudinal direction of the connecter. It is mounted in an opening 10, Figure 3, formed between the webs 11 of the pin 8 (a pin construction which may be described as hollow). A spring actuated plunger or pin 12, see especially Figure 4, passes downwardly through the hollow shank of the head through the lug 14 on the fitting 9 which lug lies in the hollow shank, and removably holds the fitting in place. A suitable gasket 15 is mounted in the forward end of the fitting, the gasket preferably being of the expansible type and having an interior annular groove which receives the compressed air, thereby forcing the front portion of the gasket forward against a mating gasket.

As shown particularly in Figure 1, the coupling face of my improved head, and the front face of the fitting 9, are in substantially the plane PATENT oFFICEf 1 of the inner wall -.of the funnels, '7. This is an important advantage. It permits the funnel '7 to be built up, that is lengthened, until the plane of the face thereof is practically in'the plane 'of the vertical centre of the front end of 'the fitting 9. The funnel thus lengthened or built up is shown at A in Figure 1. An increase in the gathering range of the coupling head of as much as 2 inches in all directions may be attained in this manner without adversely affecting interchange with. previous heads.

When in the coupled position shown in Figure 1, the pins 80f my improved coupling heads rest in sockets 16 formed in the apex of the funnels, as illustrated; These sockets are preferably of approximately the depth shown, and inasmuch as mated heads cannot rock? one upon. the other whilethe pins 8 are held in these sockets by the pressure of the spring 17, the sockets and the pins constitute interlocking means for preventing relative movement of the mated coupling heads. The joint formed between a pair of these improved heads is therefore immovably rigid so long as the cars remain coupled.

To permanently carry a suitable interchange for coupling a car not having the connecter to one equipped with it, I provide a perforated lug 18 on the underside of the head. A desirable form of interchange, similarly connected, shown in my co-pending application, Serial No. 229,235, filed October 27, 1927.

What I claim is:

1. A connecter head having a pin on one side and'a funnel on the other side of the longitudinal center line thereof, and also having a portion provided with a flat coupling face which lies on mating head, ,a conduit mounted in said opening 2. In a connecter head having a pin on one:

side and a funnel on the other side of the longitudinal center line thereof, and also having a portion provided with a flat coupling face which lies on both sides of said longitudinal center line, said portion having an opening arranged in substantially the longitudinal center line of the head, said funnel having its apex extending rearwardly from said face and the inclined surface thereof being substantially straight and merging with and lying in the same plane as said face, said pin extending forwardly from said face and having a cross-sectional area'substantially less than the cross-sectional area of said funnel, said pin having its front end rounded to interlock with the apex of the funnel in a mating head, a conduit mounted in said opening andarranged at substantially a right angle to said face, said'conduit having a perforated lug thereon, said head having a recess for receiving said lug, a springpressed latch carried by said head and extending transversely of said recess for engaging the perforation in said lug, said conduit being removable rearwardly from said opening when said latch isdisengaged from said lug.

3. In combination, a connecter head having a pin on one side and a funnel on the other side of the longitudinal center line of the head and also having a portion provided with a flat coupling face which lies on both sides of said longitudinal center line, said portion having an opening therein arranged in substantially the longitudinal center line of the head, a supporting shank for said head extending-rearwardly thereof on substantially said center line of the head, a coiled spring carried by said shank for pressing said head against a mating head, said funnel having its apex extending rearwardly from said face and the inclined surface thereof being substantially straight and merging with and lying in the same plane as said face, said pin extending forwardly from said face and having a cross-sectional area substantially less than the cross-sectional area of said funnel, said pin having its front end rounded to interlock with the apex of the funnel in a mating head, a conduit mounted in said opening and arranged at substantially a right angle to said face, said conduit having a perforated lug thereon, said head having a recess for receiving said lug, a spring-pressed latch carried by said headand extending transversely of said recess for engaging the perforation in said lug, said conduit being removable rearwardly from said opening when said latch is disengaged from said lug.

4. In combination, an automatic train pipe connecter head having a pin on one side and a funnel on the other side of the longitudinal center line of the head and also having a portion provided with a flat coupling face which extends diagonally of the longitudinal center line of the head and which lies on both sides of said line, said fiat portion having an opening therein arranged in substantially the longitudinal center line of the head, said head back of said opening being provided with a recess, a portion of which is formed with spaced walls, a supporting shank for said head extending rearwardly therefrom on substantially the center line thereof, a coiled spring carried by said shank for pressing said head against the mating head, a conduit mounted in said opening in the head and projecting rear- Wardly thereof at substantially a right angle to said flat face, said conduit on one side having a lug adapted to fit between said spaced walls of said recess, and a latch engaging said walls and said lug for locking the conduit in said recess.
