ELECTRIC TRAIN-CONNECTOR.

SPECIFICATION forming part of Letters Patent N0. 706,226, dated August 5, 1902.

Application iiled November 29, 1901. Serial No. 83,985. (No model.)

[o all whom, .it may concern:

Be it known that we, CHARLES E. FELT and DANIEL A. KIMBARK, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Electric Train-Connectors, of which the following is a full, clear, and exact specification.

Our invention relates to that class of electric train-connectors employed for connecting the wires or conductors of railway-cars where the wires of one car are necessarily disconnected `from those of the contiguous cars to permit the cars to separate; and the invention has for one of its important objects to provide a connector which shall be of such a character that the knife-switch principle of Contact may be employed, whereby a perfect electrical communication will be iusured and sparking avoided.

Another object of the invention is to cause the members of the connector to automatically separate should the connectors be forgotten when the cars are uncoupled.

Another object ofthe invention is to have the construction such that one member of the connector may be inserted from below, whereby it will be more convenient to handle and a large part of the slack heretofore required in the short conductors between the carsmay be dispensed with.

Another object of the invention is to provide the connector with a jumper as a permanent part thereof, which shall be of the knife-switch character, for connecting the conductors or wires of the same car together when the car is cut loose.

A still further object of the invention is to provide a lug for the stub ends of electric wires or conductorslwhich may be readily connected to either the side or the back of the electrical member with which connection is desired.

Vith these endsin view our invention con sists in certain features of noveltyin the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to thel accompanying drawings and more particularly pointed out in the claims.

In the said drawings, Figure] is a side elebottom view with the male member and the bottom cover of the female member removed from the line 3 3, Fig. 5, down. vertical longitudinal sectional View of the two members complete, taken on the line 4 4,

Fig. 2. Fig. 5 is a similar section taken on the line 5.5, Fig. 2. Fig. 6 is a transverse section taken on the line G 6, Fig. 5. Fig. 7 is avertical longitudinal sectional view of both members, taken on the line 5 5, Fig. 2, showing the members in the act of being pulled apart by accidental longitudinal strain, as hereinafter described; and Fig. 8 is a detail perspective view of a clutch which constitutes a part of the lock hereinafter described.

The connector comprises two members-a male member and a female member--one of which is secured to the car in any suitable position or place, but usually and preferably 'under thehood over the platform, while the other is connected to the short conductors which extend between the cars and is adapted to be engaged with the member fixed on the car or disengaged therefrom at will, as may be necessary. Inpractice it is preferable to secure the female member to the car, and this one will be first described.

l 2 3 are a plurality of metallic plates equal in number to the number of wires or conductors 5 6 7 carried by each car, three being ordinaril y employed. Each end of each of these plates l 2 3 is provided or formed with an angular bend comprising two parts 8 9, prefer ably arranged at right angles to each other and situated near one end of the female member in such a position that the angular part 8 will be opposed to the end of the female member, while the part 9 will be opposed to the sideor top thereof, and these plates l 2 3 are covered over at top by a cover 10, composed of any suitable insulating material, and at the end by a plate ll, of insulating material, cover l0 being formed with an aperture directly opposite each of the angle parts 9 and the plate 1l with an aperture directly op- Fig.4is a4 IOO posite each of the angle parts 8, so that the conductors 5 6 7 may be inserted through either the side or the end ofthe connector, as the conditions of each particular case may require. In order that the conductors 5 6 7 may be secured to one or the other of the angie parts 8 9 belonging to their respective plates 1 2 3, a lug 12 for each of the conductors is provided. 'lhese lugs are each formed with a socket 13, into which the metallic stop 14 of the conductor is inserted, and the end of each lug is provided with a threaded tenon l5, adapted to be inserted through eithera perforation or socket 16 in the angle part 7 or a similar socket or perforation 17 in angle part 9 and firmly bound therein by nut 18, threaded on tenon 15 and engaging against the opposite side of the angle part through which the tenon is inserted. By this means it will be seen that one or more 'electric conduct-ors may be readily attached electrically to the, part with which connection is desired without unduly bending the connector and without having any contacting surface eX- posed, it being understood that the apertures in the insulations 10 11 being formed in each instance either in the side or the end, according to the requirements of the particular case.

To the plates 1 2 3 are secured lingers 19 2O 21, respectively, arranged in pai rs and con stituting the forks of the female member. These lingers may be attached to their re- Ispective plates 1 2 3 in any suitable Way or, if desired, formed integrally therewith. In

the example shown the plates 1 2 3 are slitted and the edges of the fingers inserted in the slits and then riveted through by rivets 22, as shown in Figs. 2, 5, and 6. Arranged between the lingers of each pair is a triangularshaped block 23, secured to the fingers by rivers 24 or any other suitable means and constiluting an incline 25. The lower edges of the fingers 19 2O 2l preferably project downwardly through a bottom cover 26, composed of any suitable insulating material and secured in any desired way to the lower edges of the end plate 11 and two plates 27 28, which constitute the sides, and a third plate 29, which constitutes the end opposite the plate 1l, thus forming a complete inclosure or box in which the

plates

1, 2, and 3 are housed, in the example shown the bottom cover 26 beingr provided with sockets 30 for the accommodation of the nuts 18. The female member thus constituted may be secured to the car or other suitable support by side brackets 3l.

The male member will now be described.

32 is a block or plate of insulating material upon which are mounted a plurality of blades 33 equal in number to the number of forks 19 20 2l employed on the female member, the blades 33 being secured to the block 32 in any suitable manner, as by means of transverse dowels or rivets 34 passing through foot pieces or bars 35 at the lower edges of the blades. These bars 35 are also formed with sockets 36, into which are inserted the stub ends 37 of the short conductors 38, which extend between the cars, the sockets 36 beinginclosed by an enlargement 39 ofthe block of insulation 32, so that the male and female members may be fitted together in the manner shown in Figs. 1, 4, 5, and 6, with the fingers between their respective forks.

The male and female members are hinged together book fashion by detachable male and female hinge parts. The male hinge member is shown in Figs. 1 and 2 in the form of a pin 40, projecting from each side of the female member of the connector, while the female part is in the form of an open hook 41, carried by the male member of the connector and engaging partially around the male part 40. The pins 40 are supported by a strip 42,

v passing around one end of the female member and secured to the insulation by screws 43 or any other suitable way, while the hooks 41 are formed on a similar strip 44, which passes under the male member of the connector and is secured thereto by screws 45 or other suitable devices, the bottom of the block 32, if desired, being reinforced by a metallic sheet 46, arranged below the strips 44.

By the means described it will be seen that one end of the male member may be readily supported upon and attached to the female member by inserting the male member upwardly from below until the hook 41 has engaged over the pin 40, when if closed bookfashion the end of the male member carrying the hooks 40 will be prevented from dropping down. In order that the opposite end may also be held from downward displacement, a pair of clutches, one on each side,'or any other suitable means is provided. These clutches each comprise a pair of pivoted jaws 47, secured to the sides of the female member ofthe connector and having their opposed sides so curved as to constitute more than one hundred and eightydegrees of a circle. To one of the jaws 47 is secured a spring 48, which overlaps the other one and possesses a tendency to force the jaws together. Immediately below each pair of these jaws is located a head 49, secured to the male member of the connector in any suitable way and having its periphery constituting more than one hundred and eighty degrees of a circle or having any other suitable form that will adapt it to enter between the jaws 47 and to be grasped and held thereby. These heads 49 for convenience are formed on a strip 50,which passes under the block 32 and up on each side thereof, where it is secured by screws 5l or other suitable devices. By the means described it will be seen that if the hook 41 be iirst placed over the pin 40 the male and female members may be thereafter locked together and held in firm contact for all practical purposes by simply pressing the heads 49 upwardly into the jaws 47; but should the cars accidentally uncouple or the connectors be forgotten when the cars pull apart the incline 25 on the female member IOO IIO

will be engaged by a companion incline 52, formed at the outer side or end of each of the blades 33,as soon as the male member receives any appreciable degree of longitudinal strain, and the male member will consequently be forced downwardly as it moves longitudinally, and thus disengage the heads 49 from the jaws 4:7 while the hook il pulls away from the pin 40, the pivotal character of the jaws 4-7 permitting of this lateral motion.

53 54 are L-shaped contact-fingers arranged between the pairs of fingers 2O 2l and connecting electrically therewith, respectively, so as to constitute a fourth fork for the reception of the jumper-blade 55, which latter, as will be understood, is employed foi` connecting two of the circuit-wires together at the end of the car when it is uncoupled from the train, so as to keep the lights in circuit with the local storage battery or other means provided on the car for supplying current when the car is detached from the main generator. These fingers 53 54 are connected with the forks 2O 2l in any suitable way. In the example of the invention shown in the drawings their transverse portions are arranged between the plate 29 and the ends' of the forks 2O 21, while their longitudinal portions extend between the two plates 2 3, butin such a manner as to be out of contact therewith, strips of fiber or other suitable insulation V56 57 being arranged between the plates 2 3, so as to avoid the possibility of electrical communication between the jumper-blade and plates 2 3 when the blade is withdrawn and at the same time constitutu ing a guideway for the blade to slide in, the blade being provided at one end with a handle or stem 58, secured to but insulated from the blade by block 59 or other suitable means and sliding through the end plate ll to the exterior, whereit is provided with a suitable handle 60. Thus when the handle is drawn out the blade 55 will be withdrawn from between the fingers 53 5ft and will then stand between the insulating plates or strips 56 57, but will always be carried by the female member as a permanent part thereof and in readiness to be inserted between the fingers 53 54:.
