Specification of Letters Patent.

' Application filed April 27,1906. SeriaI'No- 314,036

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 Traveling Cranes; and I do hereby declare thefollowing 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 traveling cranes, and more particularly to improvements on the crane shown and described in my application, Serial No. 305.107, filedMarch 9, 1906.

In my pending application the hoist ropes or chains are suspended from two pairs of drums and pulleys overhanging the sides of the crane and depend outside the main cranegirders; I

My present invention consists in main girders, each made up of separated sections, and a trolley having two pairs of drums and intermediate sheaves located in a plane between the separated sect-ions of each girder, whereby the main hoist-chains depend between said separated sections, thus sustaining the load within the outer wl1eelbearings oi-the main trolley.

My invention further consists in providing the bridge with platform on opposite sides of each sectional main girder extending throu ghout the lengthot' the bridge, thrs permitting ready and easy accessto the trolley and its mechanism or to the driving-gear of the bridge in the eventof a breakdown of any of said parts. a i

My invention further consists in the parts and combinations of parts and in the details and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in end elevation of my improved trolley, the traveling bridgebeing shovmin. transverse section. tion-on' the line A A of Big. 1 and Figs. 3 and 4, are views in section and side elevation, respectively, ofthe ladle-bar-carrying devices, the ropes and hoist-drums being shown diagrammatically. 'The' traveling bridge is adapted to .travel on an elevated .trackway running lengthwise the mill or foundry. This bridge is composed of the usual end carriages, (not shown,)

-two sectional main girders on which the main of construction, as will be more fully descril: ed,

Flg. 2 is a view in sections, as clearly shown in Fig. 1. I 15 15 and 16 16 are all alike, their constru c- 0 trolley travels, the sections constituting each girder being parallel and disconnected from end to end,.and two. parallel intermediate girders on which the auxiliary trolley travels. One main girder is composed of the sections 2 and 2 and the other of sections 3 and 3, the four sections constituting the girders lzeing secured at their ends to the end carriages. These sections or girders 2 and 2 and 3 and 3 are each preferably made up of I-beams, and each is provided on its top with a rail 5, on which the flanged wheels 6 of the trolley 7 rest and move. The bridge is carried on the trucks 8,two to each end carriage, and each truck is mounted on two flanged trackwheels 9, Which travel on the elevated tracks supporting the bridge.

The trolley 7 is provided at its four corners with the compensating-trucks 10, each of which carries two track-wheels 6, arranged side by side, as shown' in Fig. 1. These trucks 10 span the spaces between the sections 2 and 2 and 3 and 3 and support the main trolley 7 on the four sections 01 the two girders above referred to. This trolley carries two double drums 15 and 15 at one side and the double drums 16 and 16 at the opposite side, the axis of the several drums telng parallel with the bridge-girders. Each pair of drums is so located with relation to the sections of th egirder on the corres ondin g side of the bridge that the hoist c ains or ropes therefrom pass down between said sec- Ihe drr ms tion being shown in Fig. 2, and more i'ully shown and descril: ed in my pending application. Serial No, 305,107, filed March 9, 1906.

, Each .drum is provided, as shown in Fig. 2, centrally with a toothed gear 17, the two 5' jgears on the drums ofeach pair of drums bemg in mesh, so that a motion imparted to one drum of either pair will transmit motion in the opposite direction to its companion drum. One drum of each pair is connected by gear-' roo ing with a motor, as fully explained in said application above referredto, so that when the motor is actuated the four drums rotate in unison. Each section ofeach double inner drum 1 5 and'16 has a rope or chain 30 se 16'5 cured thereto, and adapted to be wound there-5 on and unwound therefrom. The two ropes or chains from 'each of the double" inner drums 1 5 and 16 at each end of the trolley pass down between the'"sections of the main no 1 o 34,pass upwardly and arounddouble sheaves sheaves 31.

girders down and around sheaves 31-, carried by-the frames 31*, supporting the ends of the ladle-carrying bar 34, while the two ropes or chains from the double outer drums and 16 at the opposite ends of the trolley pass 'down and around sheaves 31, also carried by the frames 31*. These eight ropes or chains after passing around the sheaves 31 in r the frames 31*, supporting the ladle-carrying bar 33, which latter are journaled on the trolley at right angles to the axis of the several hoistdrums and in a plane between said drums, as clearly shown in Figs. land 2, and from them down between thesections constituting the main. girders, and are secured at their free ends to the ends of the levers 35, pivotally secured in the frames 31? above the 4 With this arrangement it will be seen that the ladle-carrying bar 34 is supported by two independent sets of ropes or of any kind.

In order to strengthen the bridge, I connect the sections 2 and 3 of the main girders and the intermediate girders 36 by horizontal and diagonal braces 39 and brace the outer sections 2 and 3 of the main girders by the skeleton frames 40, the latter also serving as .a support for the platforms 41, which extend throughout the lepgth of the bridge, similar platforms 42 being located between the main and auxiliary girders; as By means of theseclearly shown in Fig. 1. platforms the trolley and the bridge driving motor 43, gearing 44, and shaft/45, which are located present instance one of the inner platforms 42,) are rendered easy of access in the event of any derangement of parts, and by means of theinner and outer platforms all parts of the main trolley may be reached without danger, and ample r'oomis provided-for the examination andyrepair or removal of any such damaged parts. 1 I

It is evident that many slight. changes might be resorted to in the relative arrange ment of parts shown and describedwithout departing from the spirit and scope of my invention.- Hence I would have it understood that I do not wish to restrict myself to the exact construction and arrangement of parts shown and described, but consider myself at liberty to make such slight changes as fairly intermediate girders.

under one of the platforms, (in the fall within the spirit and scope of my invention;

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

1..The combination of main girders, a

trolley thereon, intermediate girders, a trolley thereon, and platform extending the length of the bridge between the main and '2. The combination of 'main girders, a-

trolley thereo'n, intermediate girders, a trolley thereon, platforms extending lengthwise the bridge between the main and intermediate girders, and platforms located outsideof the main girders and extending lengthwise the bridge.

3. A trolley having four drums arranged in pairs, the drums of each pair being parallel and side by side and a pairof sheaves at right angles to and in a plane passing between the drums of each pair.

4. A trolley having four drums arranged in pairs, side by side at opposite sides of the trolley, with their axes parallel with each other and with the bridge, and .a' pair of sheaves with their axes at "right angles to thedrums, the sheaves being located m a plane passing between the drums.

5. The combination with a bridge, the

main girders of which are composed of separated sections, of a trolley having four drums arranged in pairs,- and hoist-ropesdepending from each 'pair between the sections of the main girders.

6. The combination with a bridge" the main girders of whichare composed of separated sections, and girders intermediate the inner sections of the main girders, of a-main trolley mounted on the sectional main girders with its hoist-chains depending between said separated sections, an auxiliary trolley mounted on the intermediate girders, and

platforms extending lengthwise the bridge etween the main and intermediate girders.

7. The combination'with a main trolley having a pair of connected hoist-drums at each end, and a pair of loose sheaves for each pair of drums, the said sheaves being at right angles to the drums and in planes between the adjacent faces of said drums, of hoistropes depending from each pair of drums and intermediate sheaves, frames, eachcarrying sheaves around which the hoist r'opes pass,

and a lever to which the free ends of said ropes are secured, and a ladle-carrying bar securedto said frames. e i A 'In testimony whereof I have signed this jspecification in the presence of two subscribing witnesses. t
