' adapted to be moved when not in useto a position alongside ot another Wall that stan( s at right angles to the Wall that has the doorway.` rThe two sections of overhead track that lie' ad] acont to suchte/'o Walls are of course connected by a curved track section so as to 'forni a continuous path for the Wheels of the carriages that travel on the two rails oi the track and 'from which carriages f the door suspended., lt is very desirable, oit course, that such curved `connecting` tract; section or corner portion should have as short a 'radius as possible, not only to allow the door to be brought conveniently close to either wall without undue length of travel ot' the said wheeled carriages but also,` that said curved connecting section shall not extend out into the rooni to any great err` tentand thereby constitute adisiipjureuient and also a possible obstruction to the nioying ot certain tall articles in orV adjacent to the corner ot` the room Where such curved connection is located. The side Walls oi"4 the curved connection hayeheretotore been spaced apart to the same extent as the two inain straight track sectionstha-t connect with it' andthe result has been that as the carriages passed through it their wheels would, by reason ot the short radiuso'f that section ot the track, corne into grinding; contact with the sidey Walls thereof and seriously interiore with the easymovernent oi the door :trono one of its said positionsto the other. Various expediente have been de! vised to obriate this objection, anion@` Which may be cited the construction shownin Let` ters Patent No, 1,188,482, `granted plune 27, 1.916., upon an application tiled by me. @While the construction there shown has been found satisfactory it involves considerable incre efr-i pense that is desirable in connection with the` installation ot (loors in' seine situations, mving to the addition to the wheeled oarriages of extra parte,` i

lt is the objectofniy present invention to te .i incnts in theJtrack itselth rather than in the wheeled carriages that run thereon, and, brietiy and broadlyv stated, i accomplish this by leaking; the curved connecting i-neniber of the `track 'Wider than the straight ack setitioiis that connect th with (except the end portions oit such stra ht sections that abut against the ends ot the curved section) and i htly tapertorniing such straightsections si D nig `'rroin end to end so `that at their inner and Wider ends they will accurateiy register or aigi'n, respectively, with the ends olE the wide curved corner seien, all as shown in the drawing. and inore particularly described hereinafter. l f in the drawing-1 y t 'i .is a top view.r partly in 4horizontal section, oit a trolley track embodying my invention; 4

.,-teterring to `the several `figures of the drawings, 5 indicates a curved track section-,adapted to be located adjacent to the corner oi!` a roonr and constituting a portion oli a track that `extends along opposite two we ls ot' a rooni in one ot' which will be 'termed a doorway yadapted to be .closed by a sliding,v door, and against the other Wall which stands at right angles thereto such `door is adapted "tobe moved When the doorway is'uncoyerecl. rThis curved track section in the construction shown (see Fig. 3) itorxi'ied ottwo side 5 placed a distintey apart and parallel With each other, the lower inarffinal .portionsoif which are bent inward and upward toitorin ordinary rails ior the wheels of a carriage to run upon, and the upper vmarginal portions of which Walls are iii \ifa`i lly turned vand connected together, such connection in the constructionshown being by anoverlying piece of sheet metal 5l spot-Welded thereto. The track structure described is of ordinaryY forni in cross-section except that such tracks are usually 'formed troni a single piece. Un account ot the curvature such 2 thc object-ion mentioned by improvei corner pieces of this cross-section are ordinarily termed by casting7 but by making the two wall members 5a separately and con-` necting them togetherby the plateeb l ani able to make them without diiiiculty of sheet metal as in the case of straight sections of track, which is of considerable advantage as the structure is, of course, lighter and the track as a whole is more uniform in appearance than where one part is a casting and the other parts are ont sheet metal. This curved section 5 is intended to be wider than the straightaway sections that `connect with it in order that more room mayy be provided for the wheels, and thereby avoid the liability so common in corner sections of short radius of having the edges of the wheels contact with and grind against the side walls or against the upturned lips Aof the rails, or both. 6 indicates a straightaway section of track which in cross-section is substantially,7 like the curved section, but, as clearly shown in F ig. 2, is made from a single pieceot sheet metal, as is usual. The only departure from ordinary practice in the construction of such trackscction 6 is that it is made gradually tapering throughout its length so that at its inner and larger end it is ot'a width` to abut against and register or aline with the ends ot the curved section 5. At its other and smaller end it is of the same width that track ot this description is ordinarily made so that it another section ot' track of said ordinary width is connected with'it, as is here shown to be the case,- the abutting ends will aline or register as usual. Such an additional track section as `last referred to is indicatedby 7. They tapering ofthe track section 6 is formed by making thebends at the upper and lower ends of the side walls of the two parts 511--5a along slightly diagonal lines instead of along parallel lines 'as in` the case ot the forming of an ordinary track .section such as that indicated by-7, The

bending up oit the lips at the inner edges of the two rails of the track will be along parallel lines, as usual, so that such rails will remain throughout the length ot the tapered sections evenly spaced apart as usual.

A tapered section 6 will abut against each end ot' the curved corner section 5, ot course, and., while it is possible to make such tapered sections long enough to constitute the straightaway portions yot' the track in and byl themselves, yet it will be found better practice to use such tapered sections only as means interposed between the curved corner section and a section ot the usual width such as indicated by l'. Ordinary sustaining brackets adapted to be secured. against a vwall will be applied to the track. In the construction shown two brackets 8 are indicated as supporting the adjacent end portions of the curved section 5 and the tapered sections 6, such brackets being of the usual construction except that they will be' `given a slight taper to make them conform to the tapering end of the section 6 so as to thereby hold the abutting parts snugly in proper alined position. @ther brackets, such as 9, are shown for connecting togetherl the abuttinglends of the sections 6 and T, and they will, oi course, also be properly shaped to snugly receive and hold such ends. To prevent endwise movement that would allow withdrawal of a track section .trom its supporting bracket l preferably indent the upper wall of the track as at l0, into which indentations the ends of bolts l1 pass, such bolts being screw-threaded through the upper walls Vot the brackets.

y my invention l provide a track that incorporates in it at the bend a short radius section of a materially wider width than is ordinarily provided, and which, therefore, allows a tree sidewise turning ot the wheels of a carriage on the track without such wheels being hampered in their rolling movements by hard scraping against the Se (UU sides oit the section or the upturned lips at the inner edges of `the track. Furthermore, by making the section 6 of the track tapering yas described l am able to provide a construction wherein notwithstanding the difference in vwidth between the curved piece and the `straight sections of ordinary size I am able to connect these several parts together in such manner as to preserve the goed appear-` ance ot the track as a whole and at the same time provide for the perfect connection ot the several sections of the track so as to insure the easy ruiming of wheeled carriages thereon.

"What I claim as my invention and desire to secure by Letters Patent, is-' l. In a trolley-track, the combnationo" a curved track section and another section that abuts at one endy against an end of the curved section, each ofsaid sections comprising a wall member and a rail member, the rail member of the curved `section being materially wider throughout its length than the rail `member ofthe other section to obviate binding of the wheels of a.l trolley against the wall of the curved section when a trolley is moving therealong.

.2. In a trolley-track, the combination ol a curved track section and another section that abuts at one end against an end et the curved section, each of said sections compris ing a wall member and a rail member, the rail member of the curved section being materially wider throughout its length than Athe rail member ot the other section to obviate binding of the wheels ot a trolley against the wall of the curved sect-ion when a trolley is moving therealong, and the rail member oi said second-namedv section gradually. de-

of substantially the same Width as the width of the i curved section and against which curved section said end abuts, the lopposite end of said second-named section being of less width than the curved section.

` 6; A curved double-rail hollow track section comprising in combination two spacedapart sheet-metal wall members having `inwardly-turned marginal rail portions and inwardly-turned upper marginal portions, and a plate secured to said upper turned portions to hold said wall members together.
