To all whom, it may concern:

Be it known that I, CLARENCE L. TAYLOR, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Vertical Charging-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 Vertical charging-cranes, the object of the invention being to provide an ingot-crane capable of being used in any building withroofchords sufficiently high to permit of the free and unobstructed movements of a bridge carand the invention consists in rying a trolley; a traveling bridge and trolley thereon and telescopic tongs-carrying devices carried by the trolley.

My invention further consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of an overhead traveling crane embodying my invention. Fig. 2 is a plan view of the trolley. Fig. 3 is a view in side elevation of the trolley, showing the depending frame rigid therewith and the tongs-carrying frame within the rigid frame. Fig. 4 is a detached view of the tongs-carrying frame. Fig. 5 is a View of a portion of the tongs-carrying frame, and Fig. 6 is a sectional view of the double cylinder and rack for turning the tongs.

Arepresentsan-overhead traveling bridge mounted at its ends on the elevated rails B and propelled back and forth on the bridge by an electric motor C, carried on the bridge,

through the shaftct,which latter is provided at its ends with pinions b, engaging the toothed wheels 0, fast to the flanged track-wheel d.

Secured on the upper faces'of the bridgegirders are the rails D, on which the trolley E travels. 2, is mounted on the flanged track-wheels e and e, the former of which are the drivingwheels.

The driving or propelling motor F of the trolley is provided on its armature-shaft with This trolley,which is shown in Fig.

a small pinion f, which latter meshes with a larger pinion f on shaft f This shaft f carries a pinion f meshing with alarger pinion f on shaft f which extends transversely across the trolley and carries the two pinions each of which meshes with a pinion f rigidly secured to the axle of its respective driving flanged wheel 6. The trolley E also carries the drum G, which latter sustains the movable section of the gripping-tongs sup port. This drum is actuated through the motor G, located on the trolley E, and the following described mechanism. The armature-shaft of the motor G carries a small pinion which meshes with a larger pinion, both of which are inclosed within the casing G This larger pinion is keyed to the shaft g, which latter carries at its opposite end the pinion g. The shaft 9 also carries the clutch G designed to prevent the load from racing. This clutch forms the subject of a separate application, Serial No. 721,109, filed by me June 19, 1899, and hence is not fully illustrated or claimed herein. The pinion g meshes with the larger pinion g on shaft and the latter carries at its inner end a piniong which meshes with the larger wheel g on the drum G.

The trolley E in addition to the motors F and G and their gearing also carries the mo tor H, which ing pump H through the gear-wheel h and h.

The trolley E is provided at the four corners of its central open portion (shown in Fig. 2) with the L-shaped angle-irons I, which latter, as shown in Fig. 3, depend from the trolley between the bridge-girders and form guides for the movable section L of the tongssupport. These angle-irons I are suitably braced together to form a rigid support for the movable section L and also carry and support the operators cage J, in which are located the several valves for controlling the admission and'escape of air from the several cylinders and controllers for regulating the motions of the several motors on the bridge and trolley and under which is carried the compressed-air tank J Suspended by cables K from the drum G is tongs-carrying frame L. This frame is comlatter actuates the air-compresslatter is mounted to turn in said bearing and is supported in said hearing by the nut M resting on the washer M the latter resting on the top of the bearing. Rigidly secured to the lower end of shaft M is the head N, provided at its sides with inclined grooves, within which rest the blocks N, carrying the tongs-arms N These arms N are pivoted at a point between their ends to the cross- .head N carried by the lower end of the actuating-rod A. This rod passes upwardly through the shaft M and is provided at its upper end with a piston N located within the cylinder N mounted on supports 0, carried by the bearing M. With this arrangement it will be seen that when the piston is in its lowest position, as shown in Fig. -t, the blocks N, carrying the tongs-arms N rest in the lower ends of the slots in the head N,

and as the slots diverge downwardly the lower ends of tongs-arms are as close together as they ever get and are of course sufficiently close to engage the end of any ordinary size ingot. By now introducing air below piston N the latter with its rod N are raised and carry with them the cross-head N and tongsarms. As the latter rise the blocks N on the upper ends thereof are forced upwardly in the converging slots and the outer or lower ends of the tongs opened. Hence when it is desired to grasp an ingot the piston N is elevated and held so until the tongs arms or jaws N are on opposite sides of the end of the ingot, and then by releasing the piston and allowing same to descend the arms Nare closed against the ingot. As the weight of the ingot and tongs is borne by the blocks N, it will be seen that as soon as the tongs arms or jaws begin to lift the ingot the weight of the latter falling on the blocks causes the latter to move down the diverging slots, and

thus close the tongs more tightly against the ingot. When the ingot has been deposited, apull upon the cross-head N releases the tongs from the ingot.

Secured to the extreme upper end of shaft M is a toothed Wheel P.. This wheel is engaged by the rack-bar P, formed on the piston-rod connecting the two pistons P These pistons operate in the cylinders P which, as shown in Fig. 4, are carried on the upper end of bearing K. By introducing air into one cylinder and exhausting any air that may be in the other the rack-bar P is moved longitudinally, thus rotating shaft M and the ingot-tongs carried thereby, thus permitting the tongs to be turned so as to squarely engage the opposite sides of the ingot. By rotating the drum G, so as to lower the cable K, it will be seen that the tongs-carrying frame can be lowered into a soaking-pit sufficiently for the tongs to engage an ingot and can then be elevated sufficiently for the ingot to be moved clear of the floor. The weight of the movable frame and tongs carried thereby is sufficient for the tongs to operate as a'wedge to separate ingots in the soaking-pit, and as the frame L fits snugly within the frame I the two parts form a structure practically as rigid as a rack-bar would be, and as the structure is a telescopic one and located below the bridge it will be seen-that it can be used in mills where it would be impossible to use the rigid rack-bar crane.

Air-pipes leading from the pump to the tank and from the latter to the valves and several cylinders are necessarily employed; but as I make no claim to any particular form or arrangement of pipes I have not described them.

It is evident that manyslight changes might be made in the relative arrangement of parts herein shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction herein described; but,

Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is
