Applieation'iled January 6, 1905. Serial'No. 239,926.

y full, clear, concise, and exact description,

reference being had to the accompanying drawing, forminga part of this specification. .f I

The present invention relats to improvements in automatic couplings which are adapted to be employed on railroad trains toA connect the sections of the train lines automatically upon connecting the cars or units of the train. f

The cars or units of railroad trains areA usually each provided with' a section of a train line, such as a pipe line or an electric line, the sections of the train line being connected between the adjacent cars or units of the train.

An object of the present invention is to provide a coupling which may be employed to connect the sections of the train line automatically upon bringing the cars or the units of the train. together.

Another object of the present invention is to rovide a coupling which will be es pecially adapted to connect the sections of an electric train line.

4The present invention has various other objects which will be apparent from the disclosure of the' invention which is made herein.

.The coupling contains a pair of coupling members which are adapted to engage each other. When the present invention is embodied in the preferred form thereof, means are provided to retain the members of the coupling in fixed positions in relation to each other while the same are in engagement. Furthermore, said members are supported by means which permit each member to move independently of the car by which itis supported whereby the cars may move relatively without changing the positions of the members of the coupling in relation to one another.

The coupling shown in the accompanying drawings which will be hereinafter described will' serve to explain the present invention. It will of` course be understood 'ous ways and` that it may be 'applied to other purposes.

The views in the accompanying drawings are as follows:

Figure 1 is a side view of the cou ling arranged between two adjacent cars o a train. Fig. 2 is a side view of one ofthe coupling members, parts thereof being in section. Fig. 3 is a sectional view on the line 3 3 of Fig. 2. Fig. 4 is a plan view of one of the coupling members. Fig. 5 is a horizontal sectlonal view taken through the coupling with the members thereof in engagement. Fig. 6 is a back view of one of the coupling members, and Figs. 7 and 8 are a plan View and a front view, respectively, thereof.

The cars land 2 each carry a coupling member or block 3 which is provided upon one side thereof with a pair of Aguides 4 and upon the other side thereof witha single 4guide 5, said guides preferably being attached to said member by bolts 6. The outer ends of the

guides

4 and 5 are inclined outwardly, and the inner ends of the guides 4 are vpreferably separated from each other. The coupling member or block is preferably provided with posts 7 which are arrangedl upon the top and bottom thereof.

Upon the back. of the coupling member are formed arms 8 which are connected to a rod 9, said rod being mounted in a sleeve 10 through which it may slide or in which it may rotate. The sleeve 10 is preferably pivoted upon trunnions 1l which bear in a yoke 12,;the stem 13 of said yoke being fastened in the outer end of a slidable tube 14 and preferably made in two parts. The coupling member is preferably suspended upon a spring 15 which is connected to a lug 16 formed upon the top of the coupling member and a lug 17 formed upon theyoke 12. may be changed by having the rod 9 slide through the sleeve 10 or revolve therein. The spring 15 will yield to permit such movements of the coupling member.

The slidable tube 14 extends into a pivoted tube I18, and may be moved inwardly and outwardly and also revolved therein. The inner end of the pivoted tube has a hub 19 'fastened thereto, said hub being journaled upon a. bracket'QO which is fastened to a suitabie par; of the car. The outer end of The position .of the coupling member the pivoted tube bears uponl a spring 21 which is interposed between a collar 22 fastened upon the pivoted tube and a plate 23 mounted upon a suitable part of the car, said collar and said plate being provided with pins which keep the spring 21 in place. y

Within the pivoted tube is arranged a flat torsion spring 24, the inner' end of which is fastened in the hub 19. The outer end of the torsion spring passes through a slotted diaphragm 2,5 which is arranged within the slidable tube 1st. When the slidable tube is moved inwardly and outwardly, the torsion spring passes through a slot in the diaphragm 25, and a pin 26 carried by said spring prevents said slidable tube from being withdrawn from the pivoted tube. The flat torsion spring tits closely within the slot in the diaphragm, and will yield to permit the slidable tube to' be revolvedslightly in the pivoted tube. f The slidable tube is preferably surrounded by helical spring 27.- which is interposed between a collar 28 mounted upon the outer end of the pivoted tube 18 and a loose collar 29 bearing against lugs 3() carried by the sleeve 10. The spring 27 presses the slidable tube outwardly and also offers a yielding resistance to the rotation of the sleeve 10 upon the trunnions 11.

If the coupling members are out of alinement when the carsm are brought together, the guides t and 5 will bring the same into alinement, saidmembers being permitted to move independently of the cars in the requi site directions. Theposts 7 of each coupling member are adapted to engage the outer ends of the guides l of the other coupling member, and the same increase the bearing surface of each coupling member. The single guide 5 of each coupling member passes between the guides @c of the other coupling member and thereby the coupling members are locked against vertical relative move ment. The guides 4t and 5 of each coupling member engage the sides of the otherk coupling member and thereby the coupling members are locked against horizontal relative movement. The coupling members are pressed firmly together by the springs 27 when the same are in engagement, the slidable tubes being forced inwardly.

The coupling members are permitted to move vertically by the pivoted tubes 18 turnn ing on the pivots thereof, or the rods 9 rotating in the sleeves 1G; and also the same are permitted to move horizontally by the rods 9 sliding through the sleeves 10 and the sleeves 10 rotating on the trunnions 11. Moreover, the coupling members are permitted to move longitudinally by the slidable tubes 14 sliding inwardly andA out- Wardly and to turn on the longitudinal axis vthereof by the slidable tubes turning. The

coupling members rua-v. therefore move in.

such directions independently of the cars by which the same are supported, that said cars may move relatively without changing the positions of the coupling members in relation to one another.

The outer face of each couplingl member may. be provided with a recess 31 in which may be mounted a plurality of contact Suipports 32. Each Contact support preferably has a contact shoe 33 formed'upon one end thereof. The other end of the contact support preferably has mounted thereon a cup 34 carrying brushes or contacts 35 and a contact shoe 36. A cable lug 37 arranged upon the baclr of the coupling member and having a cable 38 of a train line connectedl thereto is preferably connected to the conM tact support by bolts 89, said bolts serving to`electrically connect the contact ,support and the cable lug, and also retain the same in position. The contact shoe 36 and the cup 34 are preferably secured upon the contact support by one of the bolts 39. rIlle cable lug 37, the bolts 39 and thev contact supports 32 are preferably insulated from the coupling member by insulating material 470.

The brushes'35 of each coupling member are adapted to engage the contact shoes 3G and 3S carried by the other member andv corresponding thereto. lhen the members of the coupling are in engagement, the ends of the brushes are sprung lbaclrwardlm and.

thus firm contact is obtained between the brushes and the contact shoes.

Each car in the train may carry a coupling member upon each end thereof, and between the coupling members of each car may extend the cables 38 of the train line, said cables Abeing connected to the contacts of the coupling members. When cars are brought together, the coupling members carried thereby will automatically connect the sections of the train line. It is obvious that the number of conductors or cables which the coupling may be adapted to connect may be varied according to the circumstances.

It will be understood that the coupling may be applied to purposes other than those which have been setforth, and that the construction thereof may be readily adapted to vsuit the circumstances under which it is to be employed. Y

The embodiment of the invention which has been particularly set forth herein for the purpose of disclosing the invention may bechanged nifyvarious ways and still retain the features which are contemplated by the claims of this specification.
