Again, by dividing the main girder into two separated sections for the passage between them of the hoistingchains the weight is borne in a planepassing between such separated sections, thus obvi ating to a large extent the tendency of the long girders to spread under the weight of a heavy load. 4

it is evident that changes in the details might be resorted to without departing from a the spirit and scope of my invention. Hence I would have itnnderstood that I do not confine myself to the exact details shown anddescribed, but consider myself at liberty to make .such changes asfairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Let.'

ters Patent, is v 1. In an overhead crane, the combination of two main girders each made up of two parallel separated sections, the latter being disconnected from end to end, a trolley having bearing on each section of said'niain girders,

intermediate girders and a trolley mounted on said intermediate girders.

2. in an overhead crane, the combination of'two main girders each composed of two parallel separatedsections, the sections comprising each main girder being disconnected from endto end, a trolley having bearing on each section of said main girders and carrying hoisting-chains which pass between said sections, intermediate girders and a trolley mounted on said intermediate girders, the

i chains from said latter trolley passing between the intermediate girders.

3. In an overhead crane, the combination with two girders each composed of two paral lel separated sections, the sections comprising each girder being disconnectedfrom end to end, and a trolley having bearing on each section of said girders, of a trackway secured to the inner sections of said girders, but be-' low the plane of the top of the latter and an auxiliary trolley mounted on said trackway.

4. In an overhead crane, the combination with two main girders each composed of two parallel separated sections, the sections con pris'ing each girder being disconnected. from end to end and. a trolley having bearing on each section of said girders, the hoist-chains of said trolley passing downbetween the sections of each girder, of a trackway secured to the inner section of said girders but below the plane of the top of the latter and auxiliary trolley on said traclrway, the hoist-chain of said auxiliary trolley depending between the rails of said 'trackway.

5.12s anoverhead-cran'e, the combination with two main girders each made up of two parallel separated sections the letter being disconnected fromend to. end,-of a troll.- ley having bearing on each of said main sections and carrying hoisting-chains which pass downwardly between the sections of each girder.

6. in an overhead. crane the .combination with two main girders each made up of two separated sections the latter being disconnected from end to end, of a trolley mounted on pivoted trucks, the wheels of the trucks 7 at one side of the trolley resting and moving CLARENCE L. manna "Witnesses E.
