SPECIFICATION forming part of Letters Patent No. 496,430, dated May 2, 1893.
Application filed May l0, 1892.
To all whom if; may concern.-
Beit known that I, WILLIAM HENRY MoR- GAN, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Locomotive J ib- Cranes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in locomotive jib cranes, and more particularly to devices for conveying the current from an overhead conductor to the motors carried by the movable platform and truck.
The object of my invention is to provide means for conducting the current from the overhead wire to the motors on the platform and on the truck irrespective of the relative positions of the platform and truck, and it consists in the parts and combinations of parts as will be more fully describedv and pointed out in the claims.
In the accompanying drawings Figure 1 is a view in side elevation of a crane embodying my invention. Fig. 2 is a plan View with the trolley pole removed, and Fig. 3 is a view of the king bolt.
A represents a truck of any approved form provided with an electric motor a and gearing b connecting same with the main driving shaft B, which latter is geared up with the axles C carrying the track wheels D.
The truck A carries on its upper surface the large spur wheel E, fast to the truck and forming a turn table on Which the movable platform F rests. The turn table can be formed independentlyof and be located within the wheel E and in either event it supports the platform F, the latter being prevented from displacement by the large king bolt I. The king bolt I is secured in bearing c shown in dotted lines in the drawings, and is provided at its lower end with an enlarged head d which latter bears against the under side of said bearing. The upper end of this bolt is screw threaded for the reception of the nut or roller head f (see Fig. 3) the under sideof which is grooved for the reception of the conical rollers g. These rollers rest on a suitable base or plate on the platform and relieve the latter and the king bolt of considerable strain Serial No. 432,499. (No model.)
when the crane is at work. The platform is vrotated by the motor H acting through the intervention of suitable gear wheels, on the shaft h (see Fig. l) the latter being provided at its lower end with a toothed wheel h which From the foregoing it will be seen that there are three motors, two of which aro on the movable rotary platform while the third is on the truck. The current is taken from an overhead wire, and as it is essential that the trolley wheel' or shoe should be in contact with the overhead wire at all times and under all conditions, it is absolutely necessary that the trolley pole should be so constructed or attached that the movement of the platform does not turn or otherwise change the relative position of the wheel or shoe to the wire.
If the trolley pole were attached to the platform it would necessarily turn with the platform land thus cause the overhead wire to ride up on the side flanges of the Wheel or shoe and thus permit the wheel or shoe to leave the wire. In order to prevent a change in the relative position of the contact wheel or shoe and the overhead wire I have connected the trolley pole M directly to the king bolt I, which is practically a part of the truck. This trolley pole is provided at its upper ends with the wheel or shoe supporting frame N, consisting essentially of the two bars'acrossing each other and pivoted at the point of crossing to a collar n3 swivele'd on the pole M. These bars n are in turn, each pivoted to the end of barsn the latter being connected together at their other ends and carrying the wheel or shoe. To the lower ends of the bars n are attached the depending links n4 which latter are connected at their lower ends to the collar a5. This collar o5 embraces the pole M and is free to slide and turn thereon and forms abearing for the lower end of spring n, the upper end of which bears against collar n3. By this ar- ICO rangement of parts the spring, by pressing down on collar a5, tends to straighten out the bars n and I1t,which constitute in eifect lazy tongs, and holds the contact wheel or shoe firmly against the under side of the overhead conductor. By swivelin g the lazy tongs to the top of pole M, the former is free to turn while the crane is rounding a curve and thus prevent any tendency on the part of the conductor to creep up over the side flanges of the Contact wheel or shoe.
The conductors pass downwardly through or alongside of the pole M and are connected to copper strips (not shown) secured to the outside of the pole and encircling same in the form of bands. These copper bands or strips are located within the box or casing O, and make contact With brushes (not shown) carried by the platform and leading to the two motors thereon. The conductors on, or in the pole, are then continued downward to the motor on the truck. By this arrangement of parts the platform is free to turn in any direction Without moving trolley pole M and the motors thereon and on the truck are always in electrical contact with wires carried by the trolley pole.
It is evident that many slight changes and alterations might be resorted to in the relative arrangement of parts herein shown without departing from the spirit and scope of my invention hence I would have it. understood that I do not confine myself to the exact construction herein described, but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is*
l. In an electric crane, the combination with a f ruck and a rotary platform thereon, of motor on the truck, a motor on the platform, a trolley pole carried by the truck and a swiveled frame on the trolley pole the said frame carrying a contact wheel or shoe, substantially as set forth.
2. In an electric crane, the combination with a truck and a rotary platform,a motor on the truck and a motor on the platform, of a trolley pole secured to the truck and a swiveled extensible frame carried on the upper end of said pole, the said frame carrying a Contact wheel or shoe.
3. In an electric crane the combination with a truck, a rotary platform thereon, a motor on the truck and a motor on the platform, of a trolley pole secured to the truck in line with the axis of the rotary platform, substantially as set forth.
it. The combination with a truck carrying a king bolt and a platform mounted on said king bolt, of a motor carried by the platform, a motor carried by the truck and a trolley pole carried by the king bolt, substantially as set forth.
5. The combination with a truck carrying a king bolt and a platform mounted on said king bolt, of a motor on the truck, a motor on the platform, and a single trolley pole carried by the king bolt and provided with conductors for supplying current to the motors on the truck and platform, substan tially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
WILLIAM HENRY MORGAN.
