OVERHEAD TRAVELING CRANE.
SPECIFICATION forming part of Letters Patent N 0. 585,277, dated June 29, 1897.
Application filed July 15,1896.
T0 ctZZ whom it may concern.-
Be it known that 1, WILLIAM HENRY MOR- GAN, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Overhead Traveling 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 overhead traveling cranes, and is designed more particularly for carrying ladies, the object being to provide devices which when ladle is elevated, as when discharging into a converter, holds the ladle suspendin g devices rigidly against movement, but which are disengaged from said suspending devices when the ladle is lowered.
With these ends in View my invention consists in the parts and combinations of parts, as will be more fully explained, and pointed out in the claims.
In the accompanying drawings, Figure l is a view in transverse section through a bridge, showing a trolley thereon embodying my invention. Fig. 2 is a View in side elevation of same, and Fig. 3 is a View in section through one of the guides.
Arepresents an elevated trackway running lengthwise the shop on which the bridge travels. This bridge is composed of end carriages C (only one of which is shown) and two girders 1), preferably box-girders. Secured to the upper surfaces of the girders D are the rails E, constituting a trackway on which the trolley F runs. This trolley F is propelled lengthwise the bridge in the usual manner by an electric motor and suitable provided near its opposite extend in the direction of the length of the bridge and are so located with relation to the bridge girders that the hoisting chains G pass downwardly on the outer side of the girders D. The two drums G are actuated by the electric motor H, carried by the trolley F, preferably at a point between the drums and geared to the drums in the manner shown, so
that both drums are actuated simultaneously to wind and unwind equal lengths of chain. The gearing shown comprises a pinion 1 on Serial No. 599,248. (No model.)
the armature-shaft of the motor, meshing with the pinion 2, fast on shaft 3. The pinion 2 meshes with the pinion 4 on shaft 5, and at its other end is a pinion (not shown) which meshes with the pinion 6. The shafts carrying the pinions 4 and 6 are each provided with a pinion, the one on shaft 5 meshing with the toothed wheel 7, fast to one drum, while the shaft carrying pinion 6 also carries a pinion (not shown) which meshes with the toothed wheel 8, fast to its drum. The trolley is provided near its front and rear ends with the transverse girders I, which latter project at both ends beyond the bridge-girders for the attachment of the depending guides J. These guides project below the bridge-girders and are secured at their upper ends to the girders I and are suitably braced on their outer sides to prevent them from spreading. These guides have flanges a and are formed with slightly-flaring months b.
Each drum carries two chains G, which latter are secured at their lower ends to the upper ends of the bail L. This bail can be of any approved construction, but is preferably provided at each side or end thereof with a frame M, to which the lower ends of the chains G are secured. Each frame carries at its upper end, at its opposite sides, two antifriction-rollers d, which latter project beyond the sides of the frame and adapted when the latter are elevated to enter the guides J, the rollers being partly overlapped by the L- shaped flanges a of the guides. Each frame is also provided on its outer face with the Vertical guiding-strips a, forming a guidinggroove within which the roller 1) of its respective guide rests when the frame is in its elevated position.
In a crane designed for carrying ladies it is desirable to support the ladle by flexible devices, so that when the ladle is lowered it can be readily moved and handled and also to enable the ladle to yield or give in the event it comes in contact wit-h an obstruction while being transported from one part of the mill to another. When, however, the ladle is in its elevated position for discharging its contents into a converter, it is essential that its bail be held immovable or rigid, so as to overcome the tendency of the ladle to swing while being tilted. This is accomplished by ICO the guides J and frames M above described. When the frames M are below the guides J, the bail and ladle carried thereby are supported solely by the flexible chains. Hence the ladle is free to be moved and free to swing. \Vhen, however, the frames M enter with the grooves, the bail then becomes locked against lateral movement, thus rigidly holding the ladle in position to be tipped for discharging its contents.
In the drawings I have shown in dotted lines the ladle discharging into a converter, and while the construction described is admirably adapted for use in connection with a converter I do not intend to be understood as so limiting its application, as the device is equally well adapted for pouring metal direct into molds.
For tilting the ladle I employ an auxiliary trolley O, which latter travels on the trackway 0, formed on the lower flanges of the bridge-girders. This trolley carries a hoisting drum and chain, which latter is designed to engage a ring or hook on the under side of the ladle and tilt the latter while the bail carrying same is held against movement.
I can, if desired,locate the guides between the bridge-girders instead of on the outside of same, and instead of employing an auxiliary trolley for tilting the latter result can be accomplished by an auxiliary drum on the hoisting-trolley.
It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention, and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In an overhead traveling crane, the combination with a bridge and a traveling trolley thereon, of a hoisting-chain carried by the trolle and carr in 'aladle a uide de endy a a c p ing from the trolley, and means carried by the ladlesupporting bail adapted to enter the guide and lock the bail, substantially as set forth.
2. In an overhead traveling crane, the combination with a bridge and a traveling trolley thereon, the trolley having flexible hoisting devices, of guides depending from the trolley, a ladle having a bail and devices carried by the bail and adapted to rest in the guides when the ladle is in its elevated position, substan- 1 specification in the presence of two subscribtially as set forth.
3. In an overhead traveling crane, the combination with a bridge and a traveling trolley j thereon, the trolley having two hoistingdrums and a chain on each drum, of guides 1 depending from the trolley, a ladle, and devices carried by the ladle-bail and adapted to rest in the guides when the ladle is in its elevated position, substantially as set forth.
4. In an overhead traveling crane, the combination with a bridge and a traveling trolley thereon, the trolley having two hoistingdrums and a chain on each drum, of guides outside of the bridge-girders and depending from the trolley, a ladle and devices carried by the ladle-bail and adapted to rest in the guides when the ladle is in its elevated position, substantially as set forth.
5. In an overhead traveling crane, the combination with a bridge and a traveling trolley thereon, of flexible hoisting devices carried by the trolley, ladle-carrying frames connected to the hoisting devices and guides depend in g from the trolley and adapted to be engaged by the ladle-carrying frames when the ladle is in its elevated position.

8. In an overhead traveling crane, the combination with a bridge, a traveling trolley thereon, and hoisting devices and two guides carried by the trolley, of a bail, two frames integral therewith and connected to the hoisting devices, and antifriction-wheels carried by the frames and adapted to engage the sides of the guides, substantially as set forth.
