ALBERT E. w. 'WYETH, on NEW-YORK, N. Y. ROLLER-SUPPORT FOR EDGEWISE MOVAB'LE oodRs AND TliACKS THEREFOR.

To all whom it mayicpncern;

Be it known that I, ALBERT E. W. .WY TH,

a citizen of the United States, residing. at

drawings.

New York, borough of. Brooklyn, in the In many largebuilding's-suchj as I. in churches,-.schools, and the1likeit is desirable to have between adj oiningrooms a very Wide doorway which is too wide to make it practicable to employ a single door, and hence a pluralityof doors are. used, such doors in some constructions being hingedtogether and in other constructions a number.

of independent doors being employed.

My invention relates to the latter class and to the kind that are adapted when not in use for closing the doorway to bearranged side by side in a pocketand adapted to be run out from that pocket one after the other and by means of suitably-curved tracks adapted to be brought into alinement. Such doors have heretofore in some instances been run into and out of the pocket by means of overhead trolley-wheels suitably connected with the doors and traveling on curved overhead tracks. It is more advantageous, however, in many instances that these large heavy doors be supported by and run upon wheels that travel upon track-rails sunk in or laid upon the floor and at the same time have such wheels so attached to the door free to turn laterally when the door is being run over a curved portion of the track. I

It is the object of this invention to provide an improved construction for attaining this end, which object is accomplished by the devices and combinations of devices shown in the drawings and hereinafter specifically described. I

. That which I believe to be new will be v Specification'of Letters Patent.

Fig. 4 is abottom view of azportion of a doorx provided with my improvements.

formed a pocket 6 wide enough: to receive 5 close the doorway betweenthe wall5 andthe 8 ,indicates' the tracks upon which: the I wheelswith which the doors are equipped travel, said tracks,.with the exception of one which is straight, being each curved, so as-to bring. a portion of each track in line with a portion of the other tracks, so that thedoors when in place in the doorway will be properly alined edge to edge.

Constructing the tracks to accomplish thisof course necessitates a curve ineach one of them with the exception of one, and to prevent anybinding" or friction at such curved portions I provide the means about tobe described for attaching the carrying-wheels to the bottom ofthe door. j

-9 9 and 10 indicate a metal frame, the

parts indicated by 9 9 being metal plates and the part indicated by 10 being a plate con- In the.

necting the side plates 9' together.

construction shown this plate 10 has its edges turned down at right angles to form flanges.

11, which rest against the inner faces of the plates 9, through which flanges and plates suitable rivets 12 pass to hold the plates totherefore, the bottom of the door is to be cut away transversely just sufficiently to provide a recess into which the plate-10 can project,

the depth of such recess being just sufficient to bring the lower edges ofthe side plates 9 in line with the lower edge of the door, and such side plates 9 are then to be secured to the door by screws passing through them near their ends, as clearlyindicated by dotted lines in Fig. 2.

It is evident from the foregoing that the Weight of the door will come upon'the top I plate 10 of the frame 9 9 10 and that by makdoor is in use.

ing the recess in the bottom of the door just long enough to receive the said plate and extending the side plates 9 considerably beyond the ends of such plate 10 a firm hold for the attaching-screws that pass through the plates 9 is afforded, and the recess will be hidden from view by these plates when the I prefer to cut out the sides of the door at each end of the recess to the thickness of the plates 9, as shown in Fig. 3 so that the outer surfaces of such plates 9 will be flush with the surfaces of the door.

13 indicates a wheel-frame, which in the form of construction shown is formed of a single piece bent to have two parallel vertical portions connected by a horizontal upper portion, between the depending parallel portions of which frame are secured axles 14, upon which are mounted wheels 15, adapted to run upon the tracks 8. The upper horizontal portion of the wheel-frame 13 is pivotally connected by a suitable pivot 16 to the cross-plate 10, thus forming a swivel connection with the wheel-frame that permits it to turn as required when the wheels strike the curve in the track. In the construction shown a washer is interposed between the under face of the plate 10 and the face of the horizontal part of the frame 13, and to secure a wider bearing at the central pivoted portion a portion of the material of the sides of the frame 13 is cut out and struck up, as

shown. In practice it will be found best to provide each door with two sets of these swiveled truck-frames, one near each edge of the door.

It will of course be necessary to provide suitable means at the top of the door for affording lateral support; but I have not shown any such means, as various devices may be resorted to for that purpose, and such devices "form no part of my present invention.

What I claim as new, and desire to secure by Letters Patent, is

The combination with a door provided with a recess in its lower edge, extending transversely entirely through the door, and a frame comprising two side plates adapted to extend across and cover the marginal edges of said recess and be attached to the faces of the door and a substantially U- shaped bridge-plate having its side ortions connected to said side plates an fitting within said recess, of a wheel-frame of less width than the recess, a swiveling connection between said wheel-frame and said bridgeplate, and wheels mounted in said frame, the axes of the wheels and the axis of the frame arranged at substantially right angles to each other, substantially as described.
