vAU'E(3TMA'.L1' C TRAIN-PIPE CONNECTER Application filed December 4, 131%, Serial My invention relates to automatic train i pipe connecters and has for its object to provlde' an unproved support for such con'neeters in which free'universal movement of the coupllng head will be allowed with the minlmum the supporting bracket.

of resistance to such movement, and in which the universal support of my improvement may "be shifted longitudinally of the car in- 1 dependent of movement of the upper'part of A further object of my invention is to provide an improved sup. porting bracket for automatic train pipe conn-ecters which will be simple and efficient, and economical of manufacture. And still another object of invention is to provide improved means for positively locking the bracket to the lug of a car coupler and for correctly positioning the bracket with respect to the lug.

tions, arrangements, and constructions descr bed 1n the followlng specificatlons,

pointed out in the annexed claims,andiIlus-r trated in the accompanying which t Figure 1 is a longitudinalelevation ofmy improved support, showing some of the parts insection.

Figure 2 is a longitudinal plan view of my improvement with some of the parts in section.

' Figure 3'is a detail of theupper part of the bracket of my improved support showing in elevation the connection between the members thereof, and

Figure 4 is an elevation of my improved support taken on the line of Figure 1,

' and showing some of the parts in section.

f Referring now to the drawingsrMy ini proved support consists of a bracket A'havdrawmgs, n

- ing a pair of ears 5 and (iadapted to be" securely clamped, as by means of bolts 7, to opposite sides of a lug 8 of the car coupler '9. Each ear is, provided with a seat orway 1i0 betwe-en which and the underside 11 0f the 1ug 8 a tapered wedge 12 is'driven. The forward end 18 of the seats 10 is curved u-pwardly to deflect the course of the forward end 14 of the wedge 12 as the wedge is driven home. lhis construction forces the forward improvement consists of the combine No. 342,456., Renewed November 10, 192s.v Y

end of the wedge upwardly around the corner 15 on the front face of the lug 8 and thus positively locks the wedge in position, g It will be observedthat the seats 10 and the wedge 12 are tapered, sothat, as the wedge is driven home the ears "5 and 6 are drawn tightly down upon the bolts 7 and are squared with respect to the lower face 16 of the lug. This construction 'efiiciently prevents back lash of the'bracket' A, and insures that at all times thebracket will be properly positioned with respect to the lug 8. Any wear upon the mating parts of the bracketand the lug isreffectively taken up by driving the wedge 12. forward. 4 i

Each of the ears Efand 6 have formed integrall-y with it'a perforated boss or seatl? 1 adapted to adjustably receive the upper ends 18 of the base 19 of the bracket A. The base i consists of a bar of iron, preferably cylindrical in cross section, formed into a U; shaped. memberas-shown, the upper ends 18 of which are disposed at substantially a right angle to the vertical walls thereof and are adjust-- a b'lymounted in the seats 17 onthe ears 12. These ends18 are threaded to receive nuts 21 whereby th'e'base 19Vmay be shifted longitudi;

vertically extending flange or projection 28,

the conduitbeing atthe forward end: of the body and the flange at therear end thereof andthe flange and the conduit being con- V nectedby spaced' wa l'ls or straps 24Qpre-fer- V I 'ably formed integrally with the conduitand the flange. he space'between the straps 24 forms-in effect a slot extending through the "pipe or member '13. The lower-end "25 of g the base 19-lies in the h-orizontal plane and extends transversely of said' hollow body and projects through the opening therein. Upon this portion 25 ofthe base 19 "I pivot ally mount a pivot bar on tie'rod' 26 the same having' perforated head 27 which embraces the-lower end 25 of the base and lies between the straps 24andwit-hinthe hollow of the body B, as shown. The tie rod extends rearwardly of said body through an opening 28 in the flange 29, and threadingly receives at its rear end a member or abutment 30 adapted to be manually adjusted along the pivot bar 26 for a considerable distance. Between this nut and the rear face of the flange 29 I mount a suitable buffer spring C. The spring surrounds the tie rod 26 and rests on a seat 31 formed therefor upon the rear face of the flange 29, and 0p. erates to maintain the flange normally in contact with the rear face of the base 19 with the body B normally disposed in the horizontal plane. Any desired tension of the spring C may be had by adjusting the nut 30, which operation will vary the force required to shift the body B from its normal uncoupled position, either longitudinally of the car or laterally thereof. Any suitable form of coupling head D may be used with my improved support and may, in any satisfactory manner, be mounted upon the body B. I preferably threadingly mount the head.

upon the forward end of conduit 22, and provide with a port 32 and gasket 33 both of which have communication with the conduit 22. i e H v To direct the fluid from the train pipe of the car to the connector, any satisfactory form of connection may be used. I show the usual section of air hose now universally in use upon railway cars, tho flexible metallic pipe may be employed for this purpose if desired.

It will be observed that the flange 23 contacts with the base 19 only at the sides-of the base and the flange, there being no contact between the flange and the base between the vertical walls of the latter.

be formed or" any desired shape in cross section, as for instance rectangular, I prefer ably form them round. This construction produces a universal joint in which .the curved faces of the mating members permit easy pivotal movement between them in all directions. e v

, In assembling my improved support the head 27 of the tie rod26 is passed over one end 18 of the base 19 and is then shifted to position on the base. Thereafter the base is hooked into the hollow body B by passing one end of the base through the body "from a side thereof after which the cars 12 are assembled onthe ends 18 ofthe base. The spring C is then passed over the tie rod 26 and positioned on the seat or lower end 25 of the base whereupon the nut 30 is applied and adjusted to place the spring placed undersuiiicient.v tension to properly support the coupling head D. This construction produces ahighly efiicient support, which will permit free universal movement to the'coupling head D with the minimum resistance to While the base 19 and the head 27 of the tie rod may such movement, and which may be adjusted longitudinally of the car coupler to compensate for wear upon the car coupler knuckle, or upon the parts of my improvement, and thus maintain a substantially constant degree of compression of the spring C at all times. Through contact of the straps 24 of the body B with the base 19 undue rotation of the coupling head and body B about their longitudinal axis is prevented.

Variations may be made in my improvement within the scope of my invention; I do not therefore desire to be limited to the exact construction disclosed.
