T all whom it may concern: in plan view in Fig. 3, and secured by screws, Be it known that I VVILLIAM J. SUMNER, a as shown, on pposite sides of a hole through citizen of theUnited States of America, residsaid plate H. The said plate H is perforated, ing at Holyoke, in the county of Harnpden and as aforesaid, 130 let the l0wer screw-threaded 5 5 State of Massachusetts, have invented new end of the hanger D pass freely through it. and useful Improvements in Adj usl-able Trol- WVithin or between said lugs J and restrained ley-Hangers, of which the following is aspecifron1 downward movement thereby is a cirfication. cular hearing-nut K, having a concentric This invention relates t0 trolley-hangers f0r groeve in its upper face, which groove is [0 supporting doors and similar objects on a cated oppositea like groove in the adjoining track whereby they are easily moved to and under side of said plate H. Bearing-balls n fr0, the object beinp; to provide improved conare placed between said nut and. plate H and necbions between said hanger and. the supwithin said concentric grooves. These halls ported object whereby the hanger is made prevent any upward movement of the nut 15 self-adjusting axially and the trolley-wheel K by hearing directly againss it and the plate is constantly free to follow the direction of H, andthe lugs J prevent eitl1er lateral 01 the track on which it runs, thereby avoiding downward movement by catching against the frictional contact with said track; and. the innut on ibs edges and lower side. The consevention consists in the construction and arquence is the door is held with j ust sufficient zo rangernent of the devices connecting the rigidity to enable it to move freely and. yet hanger t0 said supported object, all as hereprevent it from having any unnecessaryplay. inafterfully described, and more particularly Said nut K is provided With spanner-holes s pointed out; in the claims. in its periphery, whereby it is, by the use of:

In the drawings forming part of this speciasuitable implement, turned 011 said hanger 25 fication, Figure 1 is a side 61(3V2t17l011, partly IJ0 adjustit properly toward said plate Hand in secnion, of a part of the upper end of a relative t0 said ballsn therebetween.
