Application led Noveinheit` 2,1, 1912. Serial No. 732,663. i' f T0 all whom t may concern: Beit known that I, MYRON COssEY, a citizen of the United States, residing in the borough, of Brooklyn ofthe city of New York, in the county Oi-KingS, in the State of New York, have invented certain new and useful Improvements in Door-Hangers, ot which the following is a specication, reifer-y ence being had to the accompanying draw-l ing, which forms a part hereof.
This invention relates particularly to twoor threespeed hangers for sliding doors 1n 4which the several doors or leaves of the compound door are geared together so that the several doors have diilerent speeds and all reach the open or closed position at the same instant.
In door hangers of this type, as usually constructed, the first door travels upon a iixed track while the second door travels upon a track supported by the first door, and so on. The doors are sometimes very heavy and the leverage which is exerted through the hanging of successive doors upon tracks carried by other doors causes lateral pressure and wear upon the balls or rollers through which the doors' are supported upon the tracks, with consequent resistance to free movement, deterioration of the hangers, rollers to be forced from the track in which they should travel. e v
It is the object oi:l this invention to provide means whereby each door may be supported upon a stationary track while the relative movement of the several doors is secured through gearing betweenthem arranged substantially as heretofore.
The invention will be more fully explained hereinafter with reference to the accompanying drawing in which the several embodiments of the invention are illustrated and in which Figure 1 is a view partly in side elevation and partly in longitudinal sectionl showing a two-speed door hanger constructed in accordance with the invention, the section bethe plane indicated by the line 1-1 the plane indicated by the line 2-2 of Fig. l, but on a larger scale. Fig. 3 is adetail view illustrating particularly the construction of the ball carrier.
z The door hanger, as delivered to the user,
is a unitary structure, with all of its parts and 4liability of the balls ork transversesection on f assembled yand 'ready foruse. I t'pcomprises ja bracketor supporting plate a adapted to' be secured to the wall b. and! tosupport ythe otherI parts of the hangeinl';
In the construction shown inFigs. Iand 60. 2 the supporting plateahassecured thereto' .aasupporting bracket c which may consist `of a beam c,'-atcp*plate c2 `and a side plate @5t-A fixed track d, for one of the doors, is
secured to some part of the supporting structure, such as the'plate a, and a xed track e, for the other of the two doors is also secured to some part of the supporting structure,- such as the plate c3. Each rail is grooved, preferably on both yits upper and ylower sides, as at Z1 cl2 and el c2 respectively, to receive balls f which are spaced apart by spacers g as usual.k Carriers z. and t', grooved internally,V as at L k2 and t" i2 cooperate with the tracks d and c, through the 7-5 balls f andare provided with hangers 7o and Z by which the doors m and n are hung from the carriers 7L and respectively. Each door, as will be observed, thus hangs substantially in the plane of a corresponding fixed track,so that the pressure on the balls is wholly in a vertical plane and there is no lateral pressure which tends to produce eX- esive wear or lateral displacement of the In order that the desired relative movement of the several doors may be provided for, one of the doors, as the door m, has "mounted in connection therewith, through the carrier L, on a stud 0 secured to the car- 90 rier, a gear p which meshes with a fixed rack, as 7^, secured to thesupporting structure and with 'a movable rack, as s, secured to the other door through the corresponding carrier t'. It will therefore be seen that if 95 motion is imparted to the ydoor m, for example, the other door n, through the described gearing, will be caused to move in the same direction asthe door m, and at twice the speedfso that both doors reachloo the open or the closed position at the same instant.
It will be seen that details of construction may be varied to suit convenience in manufacture and diii'erent requirements of use 105 and that whether the invention be embodied in onev specific form or another, the structure in which it is embodied comprises a lixed rail for each door, Jfrom which the doo-r is hung through a suitable carrier',- 110 y While gearing is provided through which the desired ,speed vofnrlovement of one door Wi th respectto another issecured.
I claim as my invention:n
A two-speed door hanger comprising a supporting structure consisting of a sup# portingy plate, a beam secured thereto,` a depending plate securedmto the beam, a lplnrality of fixed tracks supported by said plateso :movable carriers *upon said lflged traeks respectively. bearing' members` inter;
posedbetween` theftop ybottom edges of said carriers and 'fixed tracks, hangers secilredltoV said carrierstosupport the several doors in substantially ythe* same lvert- 4cal Vplane With the tracks respectively, a o stationary rack Vcarried lby :the supporting beam, a seconderack secured to onefof said movable carriers, and a gear carried by an- Y other of said movable carriers and engaging 20 Vboth of said racks whereby one carrier has al different speed with respect tof the other :Carrier a L f V.This specification signed and witnessed this 20th day of November A.
