4Be it known that I, WILLIAM A. LoUDoN, a citizen of the United States, residing at Chicago, in' the county of Cook and State of aconfined space.
Illinois, have invented certain new and vuseful Implrovements in Trolley Stands, of
which t e following'is a specification.
This invention relates tounderrunning.

invention aims toprovide'a pole that so that it is 'of especial advantage in tunnel The invention consists in a trolley pole having its heel hinged to a spring plunger housed in a` suitab e standard or column, and fulcrumed on a link which is hinged at other end to the side of'said standard. The
height of the standard is such that the ole ,Y can be turned down alo side of it, an in this position the standar and pole can be rotated to reverse the pole. In the accompanying drawing, Figure 1 is an end elevation/of an electric mining locomotive e uipped with my improvedtrolley pole andf ocated in a tunnel; and Fig. 2 1sl a sectional elevation of ftheI--standard anda part of the pole, shown on alarger scale.
'.On the top of the electric locomotive 1 is secured the'pedest'al 2 which affords an upright cylindrical bearing for the rotatabe tubular standard. A cap 4 is fastened'on plunger is ch suppentsa wasn r 11 serving as onethe top of said standard, and at one side of said cap are ears 5 to which is hinged a link 6; A socket 7 for the trolleyjpole 8is hinged to the upper'end ofthe link, and the heel of the standard 3.j "`The` lower end of the lwithreaiip to receive a nut l0 Speciiication of Letters Patent.

The tension o the spring canbe adjusted by means of the 'nut so as to produce the requisite upward ressnr'e of the trolley wheel 13 against t e overhead conductor,
the upper end of the link 6. being the fulcrum onlwhich the trolley-poleswings. 1
` The trolley pole is preferably made of wqod,
