15 Claims.

This invention relates to train line connectors, particularly of the type designed for use with couplers that are rigidly interlocked. My invention comprises a novel mechanism simple in construction and positive in operation and includes a pair of relatively movable members, one of which is fastened to theunder side of the car coupler and the other movable with respect to the first member and provided with suitable connections and ports for the air, signal and steam lines. The novel features to be described and claimed will be more clearly understood in conjunction with the accompanying drawings, in which:

Figure l is a view in side elevation of a pair of my train line connectors applied to interlocked couplers.

Figure 2 is a bottom plan view of Figure l with a sectional view of one of the connectors taken on line 2--2 of Figure 1. 1

Figure 3 is a vertical sectional view through a pair of engaging connectors, taken on line 3-3 of Figure 2.

Figure 4 is a front view of a connector.

Figure 5 is a transverse vertical sectional view taken on line 55 of Figure 3, and

Figure 6 is an elevational view showing a connector in uncoupled position.

Referring to the drawings, I have shown my improved connector in conjunction with a typical tight, lock coupler, similar to the one shown in my application Serial No. 53,012, filedDecember 5, 1935, although it will be understood that the connector may be used with any suitable tight lock coupler. In the drawings the couplers A and B are similar in construction, each being provided with projection l adapted to enter a recess 2 in the opposing coupler to align and position the couplers during the coupling operation. The

horizontal surfaces 3, 3 of each projection are positioned between corresponding surfaces 4, 4 of each recess to limit relative vertical movements between mated couplers. Extending downward from the bottom of each coupler is a vertical web 5 terminating in a substantially horizontal flange 6, which flange provides a seat or abutment for fastening the train line connector.

Referring particularly to Figs. 4, 5 and 6, it will be seen that the connector comprises an outer housing 1 provided with vertical walls 8, bottom wall 9, and top wall l0, forming a box-like structure, the top wall being extended laterally as at I l and I2, so as to form horizontal flanges underlying fiange 6 of the coupler. Openings are provided in the flanges 9, H and I2 to receive bolts l3, which together with nuts l4 secure the housing to the bottom of the coupler.

Mounted in each housing and adapted to slide relative thereto is a connector member Hi. This member is provided with lateral projections 11 5 that enter longitudinally extending slots l8 in the side walls 8 of the housing member 1. These slots, as will be seen from Fig. 2, do not extend clear through the housing but terminate in shoulders or abutments l9, which abutments when en- 10 gaged by the projections l1 serve to limit forward movement of the connector member relative to the housing. Side walls 8 of the housing are shown offset at I5 and the lower end of member [6 narrowed a corresponding amount so as to 15 prevent incorrect assembly of the parts. If desired, this construction may be omitted without affecting the operation of the device.

Extending rearwardly from the front portion 20 of the connector member is a hollow pro- 20 jection 2| which serves as a conduit for the air used to operate the brakes and also forms positioning means for

springs

22 and 23, which springs are housed in a recess 24 in the connector member l6. These springs bear at one end against 25 abutments 25 and 26 in the forward part of the recess and at the other end against a transversely extending member 21. Side walls 8 are recessed at 49 and 50 to receive the ends of member 21 and the latter is secured to laterally extending 30

flanges

36 and 31 of the housing by bolts 28 and nuts 29. An opening 21' in member21 receives the rearward projection 2| of member IS. The purpose of the recesses 49, 50 is to position member 21 forwardly a distance such that the heads 35 of bolts 28 will not intefere with the train line connections to be later described. Member 21 is offset rearwardly intermediate the ends thereof, as at 38, and provided with

slots

39, 39 which in effect are continuations of slots I8 so as to obtain 40 the desired rearward movement of the connector member relative to the housing. When the member 21 is assembled with the housing, springs 22,

23 are placed under initial compression, so that when the connector is not coupled with a mating 45 connector the springs move connector member l6. forward relative to the housing until projections i1 engage the abutments 19.

It will be noted that considerable clearance is provided between connector member l5 and the 50 inner walls of housing 1 and also between prejection 2| and opening 21' in member 21. This clearance assures flexibility between the housing and connector member so that two mated.con-

v'nectors in effect float in their housings and are 55 34 for the signaL air and steam lines respectively.

These gaskets are of the usual type and when the connector is uncoupled, are adapted to project a slight distance beyond the front face 35 of the connector member. When two connectors are engaged in the coupling operation of adjacent cars they are moved rearwardly, thus compressing

springs

22 and 23 in each connector. The pressure exerted. by the springs forces the gaskets into close contact to prevent escape of -the air or steam.

The opening 30 extends at right angles to the connector at the rear end thereof as at 40 and may be threaded to receive pipe 4|. As will be clearly seen from Figs. 1 and 2, the flange 36 has been curved in a forward direction at 42 so as to provide a recess to receive the pipe when the connector is in a forward position. The pipe 4| extends laterally outward beyond the flange 36, so that the union 43 which joins the pipe with the signal hose connection 44 will not come into contact with said flange.

The hollow projection 2| is threaded at its rear end to receive an elbow 45 which is joined to the air hose 46 by means of a pipe 41 and a union 48.

The opening 3| for the steam line is preferably bent at an angle at the rear of the connector, as shown at and threaded to receive a pipe 52 that is connected with the steam hose 53 by a union 54. In this manner the steam hose con nection is positioned laterally of the center line of the coupler and thus interference with the carry iron and other parts of the car structure is avoided. It will be noted that at the left side of Fig. 2 the steam hose connection on the connector is illustrated by dot-dash lines, full line not being shown due to the section being taken on the transverse center line of the connector.

It will be understood that the train line connectors will be prevented from separating by the interengaged knuckles and locking mechanism of the car couplers. I prefer to take care of the preliminary alignment of the connectors both vertically and laterally by means of the guiding surfaces on the car couplers. To this end the front faces of the connectors, even when projected fully forwardly, are positioned to the rear of the gathering surfaces of the respective car couplers. However, it is not feasible to align the connectors by such means to such an extent that they will at all times come into an exact alignment. I, therefore, provide the connectors with guiding surfaces sufficient to perform any additional gathering that may be necessary to make them properly engage each other.

Referring particularly to Figs. 1, 4 and 6, each connector is formed with an upper forward projection 55, which for the purpose of illustration I have shown on the same side of the connector as the knuckle of the car coupler. On the opposite side of the connector and below projection 55 is another projection 56. Directly below projection 55 and directly above projection 56 the member |6 has been recessed at 51 and 58, respectively. The bottom of projection 55 and the top of projection 56 are formed with oppositely sloping

surfaces

59 and 60, respectively, which surfaces extend into and form the top and bottom walls of the corresponding recesses respectively. When a pair of connectors are brought together the projection 55 of one connector will enter the recess 58 of the opposing connector, and at the same time projection 56 of the first connector will enter recess 51 of the other. If the connectors are slightly out of alignment in a vertical direction, the sloping

surfaces

59 and 60, one on each connector, will engage, and as the connectors continue to move toward each other, the above surfaces will bring them into vertical alignment. It will be apparent that no matter which connector happens to be above the other, one surface 59 and one surface 69 on each connector will be sufiicient to gather the mating connectors within the gathering range of these surfaces.

I have arranged the springs in my connector and provided for sufficient longitudinal movement of the connector member such that if one or more of the springs in one of two mating connectors are broken, the connector member of the opposite connector will force the connector member of the first connector into its housing, the capacity and travel of the springs of the second connector being sufficient to maintain a tight connection between the gaskets.

To assist in aligning the connectors in a horizontal direction the

projections

55 and 56 may be beveled as at 6| and 62, and in a similar manner the

recesses

51 and 58 may be constructed so that their vertical walls are sloped as at 63 and 64. The projection and recess engagement also serves to prevent relative vertical and lateral movement's between the mated connectors. It will be observed that wall 63 of recess 51 is offset inwardly from wall 66 of member l6, forming a shoulder 61 at the bottom of the recess. The bottom surface 68'of the projection 56 on the opposing connector will engage the shoulder 61 and also prevent relative vertical movements of the connectors.

If desired, the connector housing 1 may be provided with

projections

69, 69 extending upwardly from flanges II and I2 in front of the horizontal flange 6 on the coupler. These projections will prevent rearward movement of the housing relative to the coupler, and thus relieve the bolts |3 from shearing stresses.

The above described connector is for use particularly in passenger service. In freight service where no steam line is used the bottom wall 9 may be moved up to a point in line with the offset portion |5 of side walls 8 'of the housing and bottom part of connector member |6 cut off a like amount to eliminate the steam line port 3|. The connector will otherwise function in the same manner as the passenger connector.
