SEIVARD S. BAB-BITT, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO HENRY AIKEN, OF SAME PLACE.

SPECIFICATION forming part bf 'Letters Patent No. 484,870, dated october 25, 1892. Application filed J' une 13,1892. Serial No. 436,476. (No model.)

.To all whom it may concern.'

Be it known that I, SEWARD S. BABBITT,of Pittsburg, in the county of Allegheny .and State of Pennsylvania, have invented a new and useful Improvement in Cranes, of-which the following is a full, clear, and exact description, reference being 'had to the, accompanying drawings, in which- Figure l is a side elevation of a chargingcrane constructed in accordance with my invention. Fig. 2 is a plan View, on a larger scale, of part of the apparatus. Fig. 3 is a vertical cross-section on the line III III of Fig. 1, but on a larger scale.

Like symbols of reference indicate like parts in. each.

The object of my invention is to provide improved means for manipulating ingots, blooms, ,and other articles for the purpose of charging and withdrawing the same from furnaces; but I desire to premise that the invention is not limited to any special use to which the apparatus may be put, nor to the precise construction shown in' the drawings, which maybe modified in various ways within the scope of the claims.

My improved apparatus comprises a crane, preferably a rotatory crane, having a j ib or carrier, a trolley mounted thereon, a peel or gripper carried by the trolley, mechanism for turning the peel or gripper radially, and mechanism for turning it axially for the purpose of tipping the metal piece or burden. These parts are of peculiar and novel construction,

and the especial features which I claim asfof my invention are summarized in the followv ing claims.

In the drawings, 2 represents the rotatory mast of a crane lprovided with my improved mechanism.

3 is the jib, which projects radially from the mast, as shown, and is preferably composed of separated parallel beams, as shown in Fig. 3. The trolley is composed, prefer ably, of two sets of trucks or carriages 4 5, mounted on the`jib and having wheels bearing thereon both above and below the beams. These trucks are connected together, as shown, and are moved back and forth on the jib bythe action of a hydraulic cylinder 6,

preferably composed of two horizontally-divided parts connected by a bolt or bolts 7, the upper parts having wheels which ride on the jib and the lower parts having bearings onthe under side of the jib andsupporting the metal-carrying mechanism, hereinafter de#LA scribed. The purpose of this construction is to simplify the manufacture of the trucks and to enable the parts to be tightened together in case of wear.

Froln the truck or carriage 5 is suspended a vertically-swiveled frame which aiords the main support for the grippers and is provided with means for rotating it axially, and from the other truck is suspended the track by which the gripping ,mechanism is supported during its radial motion. This division of the trolley into two separate trucks er carriages is for many reasons convenient and desirable; but thc invention is not limited thereto. t

The vertically-swiveled frame above mentioned is constructed as follows: A frame or platform suspended from the truck 5 has at its lower end a circular base-plate 10, having a marginal llange 11, which fits over the circular head 12 of an upright frame 13. A vertical bolt 15 extends up from the frame 13 and through a socket on the plate 10, and is. provided at its upper end with a nut 16, which holds the parts together. The part 15 thus serves the function of a king-bolt or axis for the swivel-frame 13. In order to rotate said frame, I fix to the bolt 15 a pinion 17, with which meshes the tooth-ed rack 18 on the plunger of a hydraulic cylinder 19, set on the plate 10. On projecting this plunger the engagement of the rack with the pinion` rotates the bolt 15, vand thus turns the frame 13 on its vertical swivel-axis. The lower part of'the frame 13 is forked vertically and is shaped to afford separated bearings 20. The grippers shown in the drawings consist of a bar 21, having at the end a gripping-head 22, and opposite thereto a sliding or otherwise movable head 23. Asshown in the drawings, the head 23 is movable longitudinally on the bar 21 toward and from the head 22, so as to engage or release an interposed metal bloom Fig. 1. Each of the trucks or carriages is IOO 't -Asihus'constructed'fhelperation'of-yhe'.' apparatusindelvering metal tonndemove 'ing'fity from the.-`fnrnace`is as follows; T olnft.

11. The combination of a metal support or grippers, a vertically-turning support therefor, a track by which the metal support or grippers is upheld during, its radial motion, a jib or carrier, a trolley by which said turning support and track are carried, and a motor for moving the trolley, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this Lith day of June, A. D. 1892.

SEWARD S. BABBITT.
