To all wh'omit't may Concern: v 7

Be itknown that-'1, JOSEPH VfRoBINsoN, a citizen'of' the 'Un'ite'dStates, residing at "-Mmri'smwn, Morris County, in the State of N'ew' Jersey, have invented certain new and useful Improvements in .Arut'omati'c Train.- P-ipdConnectors, of which the following is "My invention relates toimprovements in automatictrainpi'pe connectors and aims to improve'eertain features of the train pipe "oonnectors described in' my earlier :"applica- 'tion's. v

Oneef the objects of the invention is to support the connector head-and the'body enits base, or supporting bracket, so that there 'will be the minimum of resistance to fi'ee universal movement of the head when connectedto a mating head, thus insuringa perfect connection between the heads and preventing them from opening up or rooking one uponthe other under the sharp mund a curve or run over uneven track Another'object of my invention is to sup ipolt {1190011'116Ct0fl162td with the minimum resistance to universal movement as afore sa' id, and proje'ct it longitudinally of the sar -by a force'the resistance of which 'to "such i longitudinal movement will increase in greater progress than the extent of such movement of the head, thus effectually avoiding undue shooks' and strains upon the 'heasd,

SUill' other objects and novelfeatures of m invention will be apparent from the followin description taken in connection with v the drawings, in which? Figure l is a side elevation of the coniiB'CtOI";

" =Fig1'11'e2 is a vertical longitudinal seohon-or the same with the'pipe connection turned partially to show in' 'se'ction Figure 3 is a horizontal longitudinalsecof the same, the parts on a mating conmeter being shown in plan;

Figures is a'fro'nt elevation of the connector;

- 'Figure 5 is a' rear elevation of the same.

"and comprises two similar halves which when "bolted to the hanger 10 I form a} loose fitting collar surrounding the body of the 'connector,'1 2 designatinglthe Opening in the basellthroug h which the body of the cm 'Iiector extends. 11 "is flflti and forms .abe'a ring or abutment for flanges or projections'13, 14, cast inte The'rear face of-the base "gral with the connector body. "The body comprisesa "hollow member or casting A slotted at33, 34,535 and '36 and cast integral with the "oppositely disposed projections the "vertical ipla'ne uniform when one car is higher "than the adjacent one. In a coiip'lingunder vertical disalign'ment, "the higher connector isrequ'ired to lift the lower one 'and'theweight "ofthe head of the higher etrnneotor tendsto force it downward,

*Wlr'ereas the weight of the head on "the awer connector "tends to "hold it down. This oausesqthe higher connector: to drop *more" than 5 the "lower one rises 5 when cou- -P1i-ngmider these Conditions, and'con'sequenti-ly thefheads tendto jam orcramp. To over come this objection, the upper flange "13 is "made of greater length than the lower one, so that the higher connector is stiffened against movement downwardly inithe vertiplane same-eas to equal the resistance 0f the lower "connectorin moving upwardly "iiithevertical plane. At its forward end the body "A "is provided with a, hub 17 which lias holes'drilled'fin diametrically opposite --"sidjes thereof toreceiveapin 18." The pin 18 passing through the holes in the hub 17 is for? the purpose of attaching'the shank 19 tothe body, the shan'kbe'ing constructed "soas to fit into the hub f7 and being pro- 'videdwithholes to receivethepin' 18; This arrangement produces --a construction in which the connector head B and the shank 1' 9w :i th 'its nipple-20 maybe readily rernove'dirom the'hubl'i. The head of the :connector comprises a fitting or"nipple 20 to which the-shank 19 is integrally conn'ected, andthe rearward end-of the fitting '20 having a port opening "21 therein which is providedwith a suitable gasket which gages a mating connector. The rod 42 it will be, noted; is adapted to rotate universally as respects. the base 11, but only in the horizontal plane as respects the pivot bar 47 While the pivot bar 47 itself is adapted to rotate in the vertical plane only as respects the base 11.

In assembling the connector the head end ofthe rod 42 is passed through the neck 36 of. the body A and the yoke or pivot bar 47 is then inserted from either side through the larger end of the tapering slot in the body until the flat section 45 of the pivot bar fits the oblong opening 414 whereupon the rod 42 is drawn rearwardly and the halves of the base 11 are bolted about the body with the ends 46 of the pivot bar 47 fittingimthe bearings 48 of the base 11. The conical: spring 38 is then passed around the rod 42 and the nut 40 is fitted on the rod 42 to suitably tension the spring and form an abutment for its outer end. The resistance of the spring and its normal compression are determined by the Weight of the con- -nector head, plus an additional resistance sufficient to prevent undue swinging of an uncoupled head; when the cars are in motion.

It will be observed that by drawing up on the nut 40 the resistance. of the spring against the body of the connector is varied and the movement of the connector head from its normal position is proportionately resisted, but the body and head are normally supported in substantially horizontal position. The nut 40 is locked against rearward movement from the adjusted, position by a pin 50 Whichpasses through slot 51 in the threaded end of the rod42. v

The operation of the connector will be clear from the foregoing description. When two cars equipped with the connector are moved into engagement the pin and funnel gathering devices on the connectors will guide the ports of the connector heads into register and any tendency for the connector heads topart angularly or rock one upon the other will. be prevented by means of the rib onthe pin which engages the groove in the funnel, and by reason of theinterlocking connections between the members 28 and the recesses 29. The connector is sosupported that it may be freely moved in any direction so as to bring the ports therein into register With the ports of opposing connectors and may be readily. assembled and adjusted to suit varying conditions of service. Undue rotation of the connector head B about its longitudinal axis is prevented by the pivot bar 47 engaging the walls of the slots. 35 and 36. It will be noted that the pivot bearing connection between the pivot bar 47 and the rod 42 is in the same plane as the pivot connection between the pivot bar -17v and the base 11, these two pivot connections of course being at right angles as illustrated in Figure 3. This facilitates the vertical movement of the heads inthe act of coupling and renders it unnecessary to have a wide slot in the member A.

It will be clear that, various changes be made in the construction without departing from the spirit of the invention, and therefore I do not wish to be limited to the exact details as shown and. described;

Having thus described my invention what I claim is:
