To all whom it may concern.-

ductors, the contact device adapted to slide along said conductors, and a detachable connection with said device. Fig. 2 is a plan of the contact device and a section of the detachable connecting part. Figs. 3 and 4 are corresponding views of another form of my invention. I

In Fig. 1 K represents a slotted conduit in-? closing the two line-conductors A and A, which are supported upon insulating-pins d from the side walls of the conduit and form the direct and return branches of the electric circuit.

C C are two bow-shaped pieces of insulating material-such as stout hickory woo.d

' connected together at their ends, as shown in Fig. 2-, and leaving a central opening or pocket between them. Upon the under side of each of these two bows are two contact makers or shoes F and F, adapted to fit onto the conductors A and A and to travel along in electrical contact therewith.

B represents a flat strip of insulating material extending into the conduit through the slot, and having embedded therein two inctallic strips a a. At their lower ends these metallic strips are bent out,- as shown in Fig. 1, and form two elliptic springs, which rest against the two shoes F and F, respectlvely. The lower ends of a and a are left free,'so that they can be readily compressed. These springs constitute an automatically-detachable connection, by which the contact device is normally united with 'the locomotive both electrically and mechanically, while at the same time it permits the ready separation or disengagement of the contact device therefrom. It is also to be observed that this spring-connection is a. yielding one, which will permit all slight movements'between the depending plow and the contact-shoe which may be necessary in order to compensate for irregularities in the line, and'that, too, without breaking the line-connection.

E E, Fig. 2, represent two metallic protecting-pieces placed in line with the insulatingstrip 13 to protect the same from wear against the edges of the slot and extending down to engage with the two ends of the insulatingframe formed by the two pieces 0 O,so as to propel the contact deviceformed by the said frame and the shoes F F.

The strip B with its protecting-pieces E E and its conductors a a form a plow anlogous to that shown 'in my patent, N 0. 305,731, dated September 23, 1884, and this plow is supported in any well-known way from an electric lccomotive or vehicle traveling upon a track over the conduit, as is indicated in said patent.

It is apparent that should'the plow for any reason be pulled upward the whole plow will be pulled out of the contact device, the springs a a slipping up out of contact with the shoes F F, and being compressed against the sides of B, so as to be readily withdrawn through the slot.

In Figs. 3 and 4 the contact-shoes F F are replaced by eight grooved rollers, two above and two below each of the conductors AA. The rollers are journaled to the bow-shaped pieces O G, which in this case are of metal, and are insulated from each other at the ends where they are joined, the whole forming a trolley which is adapted to travel along thetwo conductors and collect. the current I form a track along the line of the conduit upon which the trolley is supported, the up- It is alsoto be .observed that the conductors themselves per set of rollers running onthe track and the lower set extending down below-the track and bearing upwardly against the lineecondoctors. The plow is of the same construction as'th'at in Figs. 1 and 2. j
