Fig. 4 is a longitudinal front of the other. These bearings are prosection of the central way on the line 1 y of vided with vertical slots at in each side to re- Fig. 3, showing the movable arms connected ceive the journals of magnet-wheels F, that by the conductors in the groove of the way. are adapted to fit therein, and around each 50 Fig. 5 is a longitudinal section of the central slotted side of the bearings there is a coil or at once pressed back into position and held there by the spring.

The wheels F are strong magnets and rest upon metallic section-plates J, that cover the central way and have direct contact with the conductor inside the car.

Near each end and in the center of the rockbar E there are depending rods G, so situated that there is one at the front and rear of each wheel F. On the lower end of these rods there are metallic plates g, near to and over the way-plate, that set well up under the wheels F on each side and extend in front and rear of the trucks. These suspended plates 9 constitute strong magnets that act by induetion upon spring-arms L beneath the wayplate, and in the event of any loss of magnetic power in the contact-wheels F that operate through the way-plate J to raise the springarms in contact with it, these suspended magnetized plates 9 aid the wheelsin performing their perfect function.

The central way H is upon the bed of the road parallel to the path over which the vehicle moves, and it is composed of a bed-piece, preferably of cast metal, about eight inches wide, having upwardly-projecting flanges h on each side. This bed-piece is lined with dry wood, vulcanite, or other suitable non-conducting material I, extending over the top of the flanges h, leavinga groove 11 within the lining, though it has been found most convenient to use strips of wood an inch thick and of sufiicient width for this purpose. The bedpiece thus constructed is covered with iron plates J about one-half inch thick laid in sections of about ten feet each in length over the groove and disconnectedat their ends to prevent the magnetic current from passingfrom one plate to the other. If found desirable these plates may be placed near together and their ends insulated by ebonite or other suitable non-conducting material j, as shown in Fig. 7. These insulators also serve the purpose to prevent water and other foreign matter from entering the groove and disturbing the conductor. Within the groove 1; ofthe central way there are spri ng-arms K arranged in pairs and independently secured to the lining I of the bottom, which are preferably made angular in form with a base-piece resting on the bottom of the groove and secured thereto by projecting pins and 0. From the outer ends of the base-pieces there are vertical portions of the spring-arms K, rising to near the plates J, covering the groove, when they are turned laterally in opposite directions from each other to form spring-arms L, which are parallel and near to the plate above. Two of these spring-arms are placed under each section-plate J andare providedwith an insulated conductor-plate l on the under side of the ends of each arm. The insulators 9% thus used may be of glass, porcelain, vulcanite, or of any other well-known suitable material. Underneath the conductorplates Z there are metallic contact-posts M secured to the bottom of the groove, which extend upward and are provided with a flat head upon which the plates of the spring-arms rest when not drawn upward to theway-plate above by the contact-magnets of the train, which move upon the section-plates over the line-conductor.

It is sometimes preferable to make the conductor-plates l serrated on their under side and to form the top of the contact-posts M with corresponding serrations, as shown in Fig. 11, so that after the passage of the train as the arm drops down upon the post to again form the regular conductor-line, the contact between the roughened plate and head of the post will be insured as against all jarring or vibrations of the road-bed resulting from the fast movement of the train over it and keeps the regular current-line intact.

Between the vertical portions of the springarms K and the pins 70 and 0, that hold their base-pieces to the bottom of the groove, there are metallic circuit-posts N, that project upward from the bottom of the groove to about the same height as the contact-posts M under the ends of the arms and terminate in an enlarged head. These circuit-posts N, together with the contact-posts M and plates Z on the spring-arms, form the points of attachment and serve as a part of the regular line-conductor n (shown in solid lines) when the contact-magnets of the train are not over them upon the sectionplates J. When the magnets F of the car are over the spring-arms, the arms are instantly drawn from the coutact-posts Mto the section-plate J beneath the magnets, thereby breaking the regular linecurreut n beneath the car and forcing it through another line of conductors. For this purpose switch-conductors r and s are secured to the posts in the groove of the bed-piece, so that when the regular line conductor a is broken the current will be discontinued at the rear and front of the car on the regular line conductor, to establish a perfect line with the switch-conductors.

As shown in Fig. 5, the spring-arms K of two sections being drawn to the plates J by the contact-magnets F 01": the car on the plates, thereby breaking the regular line conductor n, the current is discontinued, takes back on the regular line n at the circuit-post N, to which a switch-conductor 1 (shown in a line of dots and dashes) is secured and follows this switch to the'pin 0, its next point of attachment, which secures one of the raised spring-arms in the groove under the magnet-- wheel of' the vehicle, the current passing down through the pin 0 into the base and then up through the spring-arm to the sec- IIO tion-plated. This raised spring-arm K then being in contact with the plate J, and all conductors in the groove beneath the car being cut off by the raised arms, the entire current of the conductor is then forced through the raised arm and section-plate to the magnetwheel on the plate, thence through the indicator in the car to the contact magnets F on the other end of the vehicle, when it passes down through another section plate and raisedarm to the pin 70, holding the arm, to which a switch-conductors is secured, (shown by a line of dashes in the drawings,) which conveys the current to the contact-post M beyond the car and the next point of attachment of the switch, where it again takes into the regular line-circuit 41 until it comes in contact with another train provided with like magnets for taking up the current, when it is thrown through the car in like manner, as before, and so on without limit to distance or the number of trains through which it may pass. I do not, however, limit my invention to the particular form of spring-arm hereinbefore described, as they may be constructed in various other forms without departing from the spirit of my invention.

As illustrated in Fig. 7, the spring'arms L may be extended beyond the contact-postsM and be weighted at O on the under side of their ends to insure their being more quickly seated on the post and to provide a steady contact therewith during the short period of jarring and vibration of the road-bed after the train has passed.

I also show another form of the spring-arm L in Fig. 8, enlarged in Fig. 9 and 10, that is more simple in construction, which is sometimes preferred, that is operated by substantially the same line of conductors as those heretofore described. In this form I substitute for the angular arm K, heretofore set forth, a coil-spring secured to the bottom of the groove and surrounding the contact-posts M to its top, where there is an arm in the form of an insulated button secured to the end of the wire and held in contact with the top of the post by the contraction of the coil. In making the additional connections with this form of arm it is only necessary to provide a substitute connection for the vertical portion of the angle-arm before described, which is readily done by extending the switchconductors from the elevated pins and 0 to the top plate of the insulated button or springarm. This spring-arm maybe made in acontinuous bar of sufficient length to cover an entire section, as shown in Fig, 12, instead of using two arms. In this instance the insulated bar or arm L is provided with a divided plate on its upper side and with a continuous plate Z on its under side, which is held down upon the top of the contact-posts Mby means of a coil-spring secured to its center and fastened to the bottom of the groove. If desired, two or more coil-springs may be used for this purpose. In this form of arm the plate I constitutes the regular line conductor between posts M of each section, and the switch-conductor r is secured to the extreme end of one of the upper plates of each sec tion-bar, and attached to the contact-post M at the extreme other end of the adjoining section, and the switch-conductor s is secured to the extreme end of the upper plate of the section bar or arm and fastened to the coilspring in the center of the adjoining sectionbar. This form of arm is more simple of construction and is manufactured at a greatlyreduced expense. As the magnets of the train pass over the section under which it is placed an oscillating movement is produced, raising first one end ofthe bar and then the other to the section-plate J, and releasing them in the same order, when they resume their'position upon the contact-posts and are held there by the slight traction of the coilspring.

From the arrangement of the conductor in the central way it will be observed that a loop may be readily attached thereto and the current carried through the stations along the wayin the same manner as heretofore in using the conductor on poles or in the ground, so that the information conveyed from one running train to another as to their location and approach can be known at the way-stations at all times. In like manner the switches along the road are readily connected by loops to the conductor of the main line in the central way.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is
