OVERHEAD TRAVELING CRANE.

Specification of Letters Patent.

Patented Feb. 5, 1907. 7

To all whom it may concern: v

' Be it known that I, OLA E oE L. TAYLOR, I

of Alliance, in the county of Stark and State of Ohio, have invented certain new and use- Granes and I do hereby declare the following to be a full, clear, and exact description of skilled in the art to which it appertains to make and use the same.-

My invention relatesto an improvement .in overhead traveling cranes, and particularly to an improvement disclosed in my Patent No. 821,136, granted to me May 22, 1906. v

In the patent above referred to the girders are in the form of I-bearns, the auxiliary girdmain girder so as to cause each to act as a In the present device the girders,includ1ng those on which the auxgirder being disconnected from the others except'at the ends.

The accompanying drawing is a view in transverse section of a bridge, the main and auxiliary trolleys being shown diagrammat- The main girders which carry the main hoist-trolley l are each composed of two boxgirders 2,disconnected from end toend and separated sulfi ciently for the free passage and movement between them of the hoist ropes or chains 3 from the main trolley. The main trolley 1 is mounted on flanged wheels 4, arranged in pairs, as she n, one pair being located at or near each corner of the trolley,

the said wheels traveling on rails 5, secured to the upper surfaces of the girders 2, thus distributing the weight of the trolley and its load evenly on the four sections constituting the main girders and bringing the weight of the suspended load outside of the plane of the inner surfaces of the main girders, thus obviating to a large extent any tendency of the inner sections of the main girders to spread. Located between the inner sections of the main girders arethe auxiliary girders 6, also of box form, provided on their upper surfaces with rails 7, on which the auxiliary trolley 8 travel These inner auxiliary girders 6 are of less depth than the outer main girders, so as to permit the auxiliarytrolley to travel freely throughout the length of the bridge without contacting with the main trolley or any part carried thereby. The v mist-chains 9 from the trolley on the auxiliary girders pass downwardly between said girders, and owing to the box form of the latter and the fact that they are comparatively close together there is but little or'no tendency to spread under the comparatively light and well-known manner, and the bridge thus constructed is designed to travel on elevated tracks.

It is evident that many slight changes might be made in the relative arrangement of parts 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 shown and described; but,

Having fully described my invention, what I claim as new, and desire tosecure by LettersPatent, is- I 1. In an overhead crane, the combination of two main girders each made up of two Parallel separated sections, the latter being disconnected l'roni end to end, a trolley havingbearing on each section of saidmain girders,

intermediate girders and a trolley on said inf terinediate girders, each section of the main girders and the auxiliary girders being of box form.

2. In an overhead crane, the combination of two main girders each made up of two parallel separated sections, each section being of box form, the sections of each girder being (IISCOIIIIQCtOdfIOIII end to end a trolley having bearing on each section of said main girders, intermediate girders of box form disconnected l'roin the main girders except at their ends, and an auxiliary trolley mounted 4 on said intermediate girders.

In testimony whereof I have signed tlns specification in the presence of two subscrib ing'witnesses.
