I Application filed March ll, 1896. Serial N0. 582,704. (N0 model.)

To @ZZ wiz/0m, it' may concern:

Be it known that I, HARRY C. REAGAN, Jr., a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Electric Railways, which improvement is fully set forth in the followin gspeciication and accompanying drawings.

My invention relates to electric railways in which the feed-wire is located in a closed conduit and is adapted to be suitably supported thereon and to serve as an axis for oscillating contacts of a novel construction, said contacts having a portion thereof provided with a resilient arm or extension, by means of which the circuit is completed between the feed-wire and cond uctor and thence to the car-motor, said contacts being actuated at the proper time by means of a magnet carried on said car, as will be hereinafter cxplained.

It also consists of novel means for charging or energizing the magnet which is employed to actuate said contacts at the proper time.

It also consists of a novel construction of collector-wheel or roller, which is constructed in sections mounted on yielding supports, whereby provision is made for positively7 insuring that some portion ot' said roller will always be in contact with the conductor under all conditions.

It further consists of novel details oi construction, all as will be hereinafter set forth, and specifically pointed out in the claims.

Figure l represents a diagrammatic view ot an electric railway embodying my invention, the same being shown as especially adapted to an underground conduit, which latter and its adjnncts are shown partly in section, the other portions being in elevation. Eig. represents, on an enlarged scale, a transverse sectional view of an underground conduit, feed-wire, and oscillating cont-act mounted thereupon and its adjuncts. Eig. 3 represents, on an enlarged scale, a side elevation of a roller or collector-wheel employed, a portion of the same being shown in section. Fig. i represents a front elevation of Fig. S. Fig. 5 represents a diagrammatic view of a small charging-motor or generator employed,

the same being similar to the one shown in Fig. l, but here shown as in detached position. Fig. (3 representsa section on lineas x, Eig. 2, showing a portion of the feed-wire, an. oscillating contact mounted thereon, and insulating or non-conducting material or washers therebetween. Fig. 7 represents a transverse sectional view ot' annndergronnd conduit, showing an oscillating Contact mounted on the feed-wire, which has one arm of rcduced thickness, so as to impart the necessary resiliency thereto. Fig. S represents a transverse sectional view ot a portion of an underground conduit, showing a modified form of device for attracting the oscillating contact-s which arc mounted upon the feedwire. Fig. 9 represents a transverse section of a modiiied form of conductor and its adjuncts. Eig. l0 represents a sectional view of the same on line y y, Fig. 9. Eig. ll represents a perspective view of said conductor removed.

Similar letters of reference indicate correspondin g parts in the several iigu res.

Referring to the drawings, A designates a longitudinally-extending feed-wire, which is supported within the closed conduit H in any suitable manner, and has mounted thereon the oscillating contacts B, the same consisting of the body portion C, which has extendin g therefrom the arm or iron armature D.

E designates a spring which is adapted to have one end seated within a pocket or cavity F, while its other end is in contact with a suitable portion of the arm D, thus tending to press the latter downwardly.

G designates the top portion of said conduit H, which it will oi' course be understood is composed ot any suitable non-conducting material, and is shown inthe present instance as being located underground and between the car-tracks.

J designates a ledge or stop located within said conduit II, upon which the arm D is adapted to rest after the car and the magnet have advanced beyond it, as will be hereinafter explained.

K designates a spring-contact which is mounted upon the feed-wire A, the extremity L thereof being adapted to Contact with the conductor P at the proper intervals, which ICO latter, it will be understood, is made in sections havin insulation therebetween.

N designates a sleeve-like body portion of the contact K, to which the latter is attached by means of the portion M, although it is evident that, if desired, the contact K can be secured directly to the armature D by means of a pin or rivet P3, as indicated in Fig. 2, it being understood that said armature D and the spring-contact K are thus enabled to oscillate freely in unison upon the feed-wire A.

rlhe conductor P is preferably of angular shape, being composed of the members P2, P3, and Q, the laterally-extending exterior member Q being located without the conduit, and said conductor being held in position between the top G and a side of the insulated conduit by means of the screws R or other similar devices.

S designates an asphaltum or other paving which is of suitable non-conducting material, which is placed over the top G of the insulated conduit H.

T designates a pin or stud, of iron or other suitable conductive material, which passes through the paving S and the top G of the conduit, so that its free end terminates at a point adjacent the armature D, but normally out of contact therewith, the function of said pin being to form a magnetic path into the conduit to the armature D, it being understood that a number of said pins are aii'ected by the magnet employed at the same time.

U designates a magnet which is supported upon the car in any suitable manner so as to travel therewith. V and lV designate conductors leading from said magnet to the commutator-strips of a suitable small hand-generator H', the said magnet U, as well as the conductors V and XV, having leading there- Afrom the conductors X and Y, which are in communication with the positive and negative poles, respectively, of the battery A', which, it will be understood, is also carried upon the car, switches B' C' being inserted in the circuits or conductors X and V, respectively, the function otl which will be evident.

D' designates a pinion which is mounted upon the shaft E' ot' the generator H', thelatter being provided with the pole-pieces D3, and having eommutators of usual construction, with which the conductors V and VF are connected.

F' designates a gear which is in mesh with the pinion D', said gear being' rotated by means of the crank-handle G', whereupon it will be seen that a 'few rotations of said gear F' will cause the magnet U to be energized whenever desired for the purpose of attracting the armature D upwardly toward the pins 'l for the purpose of making a contact between the resilient arm or strip L or its equivalent and the conductor P.

J' designates a collectorwheel which is shown in detail in Figs. 3 and 4, the same consisting of a plurality et disks or rings K',

which are provided with grooves or ridges, as shown in Figs. l, I3, and a, the several disks composing said wheel being supported by means of the yoke L', which, it will be understood, is carried upon the car in any suitable manner, the conductor M', which leads from said yoke L' to the car-motor N', mounted on the axle P', serving to complete the circuit between the feed-wire A and said motor, as will be understood from Fig. l.

Q' designates sockets which maybe of any desired number, the same being located within the inner periphery of the rings K' and having one end of the springs R' seated therein, the other ends of the latter being seated in the sockets S', which are located in the hubs T', it being of course apparent that the number of sockets Q' and S' must be in alinement with each other when the springs R' are inserted therein, said springs having the function of yielding spokes, whereby it will be seen that it' any slight obstruction, as a pebble, stick, the., is encountered on the conductor Q, one or the other of the disks K' will still remain in contact with said conductor, since, ii its neighbor is raised by the obstruction, it will not necessarily raise the adjacent ring by reason of the yielding connection between said rings and the hubs P'.

In Fig. 7 is shown another embodiment of the principle of my invention, Y' designating the body portion of the oscillating contact, which is mounted on the feed-wire A, as before, and has the arm or iron arlnature Z' attached thereto and projecting' therefrom, as indicated,while the opposite extremity oi' said contact is of reduced thickness, as indicated at A2, and is thus caused to be more or less resilient and thus impart a downward movement to the armature Z' after the contact has once been made between it and the conductor P, said down ward movement being positively assured by the spring E, while the abutment A3 serves as a support for said arm or armature Z' when the contact is broken.

In Fig. S the construction is substantially the same as in Figs. l and 2, the only dil't'erence being that the pin 'l is replaced by the pin B3, which has in its lower extremity the socket C2, in which is inserted the pin D2, suitable insulation L2 being attached to the extremity of the latter, whereby it will be apparent that the arm or armature D will never come directly in contact with said pin D2.

In Fig. G is shown the manner of insulating the contacts B from each other, the same being threaded upon the Afeed-wire A and each having interposed between itself and its neighbor the sleeves or washers B2, of suitable Vlibrous or other non-conducting material, the object ot which is evident.

The operation is as follows, reference being First had to Figs. l and L): The contacts B normally assume the position seen in dotted lines, the extremity ot the iron arm or IOO IIO

armature D resting upon the ledge or abutment J and the spring-contact L being then removed from contact with the conductor l), the spring E also assisting to hold the arm D in its inferior position, in which position the circuit. is broken. As the car progresses, the magnet U, when it reaches the pins T, will cause the lines of force to enter theI same, and thus will instantly attract the armature D, the same then assuming the position seen in full lines in Figs. l, 2, 8, and 9, whereupon it will be seen that the circuit is completed from the feed-wire to the conductor P and thence to the lateral portion or tread Q, and through the wheel J/ and its connection to the car-motor N'. After the progression of the car the magnet U, moving therewith, leaves the pins T, and the contacts D, falling by gravity, their movements being assisted by the spring E, assume the position seen in dotted lines, the circuit between the feedwire A and the conductor P thus being broken, while the downward movement of the armature D is aided through the agency of the spring-contacts L, as will be evident. The operation in Figs.,8 and 9 is substantially the same, the resilient contact A2 being the full equivalent of the contact L. (Seen in Figs. l, 2, and 9.)

When for any reason it is desired to energize the magnet U, so as to cause the lines of force to pass through the pin T, and thus attract the armature D, Z, or Ul, as the case may be, it is only necessary to employ the auxiliary device seen in Figs. l and 5 and to give a few turns to the crank-handle G of the small generator H, which is to be carried on the car, whereby the magnet will be instantly energized, provision being also made for utilizing the battery A with said magnet, as indicated in Fig. 5, said magnet being normally in connection with the main circuit.

The construction in Fig. 9 is substantially the same as in Fig. 2, except that the pin T is now designated as B3 and is provided with a socket C2, in which the pin D2 is inserted, said pin having insulation E2, of anysuitable non-conducting` material, attached to its extremity, so that the armature D will never come in contact with said pin D2 under any circumstances, it being understood that this is the case in the other constructions.

l desire to call especial attention to the function attained by the employment of the resilient portion of the contacts L, U, or A2, (seen, respectively, in Figs. l, 2, 7, 8, or 9,) since it will be evident that by reason of the resiliency of said contacts the tendency will be for the armature D to be sprung back after the circuit is once completed and to fall upon the abutment J or A3, as the case may be, the downward movement of said armature being further positively assured by reason of the spring E.

The manner of operation of the conductorwheel J has been already explained and it is thought will require no further description.

In Figs. l0 and ll l have shown the preferred manner of constructing the conductor P, it being noted that that portion of the same which extends within the conduit may be recessed at intervals intermediate the contacts, there being as many depending arms P4 as there are contacts, thus effecting a great saving of material and reducing the weight and expense to a minimum.

lf desired, instead of recessing the depending portion of the conductor P, depending pins may be attached thereto which have the same function, as is evident.

The arm or armature D is in practice made of magnetic material, while the resilient strip L is of non-magnetic material.

lt will of course be understood that various changes may be made in the manner of mounting an d assembling the different elements constituting my invention which will come within the scope of the same, and I therefore reserve the right to make such changes as will come within the spirit of my invention, and do not desire to be limited in every instance to the exact construction I have herein shown and described.
