DOOR-HANGER.

Specification of Letters Patent.

Patented Jan. 6, 1914.

Application filed. June 6, 1912. Serial No. 702,085.

Be it known that I, ABRAHAM PERLMAN, a citizen of the United States, and resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Door-Hangers, of which the following is a specification.

This invention relates to improvements in door hangers and more especially to antifrictional sliding doors.

The primary object of the invention is to provide a hanger to be employed for supportingany number of sliding doors which it may be desired to employ in a set for closing an opening adapted to be mounted upon roller bearings and in such a manner that each door of the set is capable of a sliding motion at one-half of the speed of the door which precedes it. i

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application and in which like reference numerals designate corresponding parts throughout the several views: Figure 1 is a plan view of two sliding doors illustrated in closed position and provided with the present invention. Fig. 2 is a side elevation thereof showing the doors in their locked closed positions, Fig. 3 is a detail vertical sectional view taken upon line 33, Fig. 2,

bars 16, which are spaced apart in parallel relations by the end blocks 17 and thus providing a central space the entire length of the tracks for the reception at both the top and bottom of the rails of portions of the traction rollers hereinafter described.

The general operation of the hanger and roller bearings will now be described, it being noted that the track 13 is provided longer than track 14 to allow for the closing of the front portion of the opening by the door 11, while the door 12 positioned upon said shorter track is limited in its movement thereon to a position for closing the opening up to the rear end of the forward door 11.

Each hanger consists of a yoke frame 18 with a strap 19 spanning the lower portion of the yoke and provided with an inwardly extending perforated boss 20 and to which are secured the bolts 21 upon which the doors hang. Spaced slightly above said strap and boss and upon either side of the latter are two stub axles 22 each having journaled thereon a roller 23 adapted to move in contact with the lower surface of the rails 16 with a central slightly tapered annular flange 2& adapted for movement between the respective rails forming each track.

An inwardly projecting top flange 25 of each hanger has a similar track 26 depending from the underneath surface thereof. Said track 26 is of suflicient length to be mounted upon as many hangers as it is desired to supply to any one door, two being illustrated for each door in the present case, the said track also positioning said han ers a proper distance apart as well as eXten ing a desired distance beyond each hanger for the purpose of giving a bearing surface upon a predetermined number of the supporting rollers employed therewith.

The movable tracks 26 of the hangers are slidably mounted upon the rollers 27, which are connected together in any number and any desired distance apart by the parallel outside strips 28, between which said .roll'ers are journaled. The strips 28 'to the stationary track 13.

a sliding of the same with its hanger rollers 23 beneath the track 13 and the upper rollers 27 .upon the top .of said track 13 with the movable track 26 in turn mounted upon the said rollers. The movement of the door 11 in this direction may continue until the stop .30 secured centrally of the track 26 of the hanger of said door 11 contacts the guide pin .31 positioned to engage the same upon the outer roller strip, the same being so positioned that at this point of engagement, the respective upper tracks of the two doors will terminate in the same plane and the doors-11 and 12 will be positioned one exactly over the other. A further movement imparted to doorll in the same direc- .tion would then necessarily also move the outer rollers and the inner track 26 secured thereto of the hangers of the door 12 and thereby imparting movement to this door.

In the closing operation the door 11 may be moved toward the left upon the outer rollers 27 until the stop 30 engages the forward stop pin 30 at which time the doors are in closed position. Such movements, it will be apparent, allow the door 11 to move at double the speed at which the door 12 will move, this being due to the fact that a movement of the track 26 of the door 11 not only propels the same upon the outer rollers 27, but also forcessaid rollers to turn upon their track 13 giving double speed. The relative positions of the stop 30 and the stop pins 30 and 31 is such that when the doors 11 and 12 are in their closed positions, the stop 30 engages the pin 30 while upon the opening movement, the stop .30 travels until engaging the pin 31 and at which time the doors are completely opened, the movement of the door 11 being at double the rate of speed .of that of the door 12, the stop pins 30" and 31 therefor limiting the movement of the door 11 by an engagcmenttherewith of the stop 30 in either the extreme open or closed position.

In connection with my improved hanger, I have illustrated a latching device carried by the forward yoke 18 and operable by the lever 46 and rod 45 carried by the door 11. This device embodies a latch 33 pivoted to said yoke 18 and having a bottom notch 34L for engagement with the keeper 35 secured A bolt 40 in spanning engagement with the latch 33 rests upon the top of the rod 45, while the expansion spring 13 normally depresses both the bolt 40 and the latch 33, thereby tendingto prevent accidental disengagement of the latch from the keeper. The latch is easily manually elevated for releasing the same by an upward movement imparted to the bolt 40 through the agency of therod 4.5 upon turning .d'o n the .ilevel" 16.

In this invention the strips 28 may be formed of square tube channel iron and in which event the connecting portion of the bracket 29 between the two tracks i 111.1- necessary. I-beams might also be used as hearing strips for the rollers with the rollers journaled in perforations through the web 7 of the beams. The -artioular form of the rollers :adds materially to the invention, the rollers which are mounted in the strips 28, being the supporting anti-f1iction members for sustaining the entire weight of the doors.

While the forms of the invention hereinafter shown and described are what are believed to be preferable embodiments thereof, it is nevertheless to be nndersto od that minor changesmay bemadein term, proportion and details of construction without departing from the spirit and scope of the invention, asset forth in "the appended claims.

Having thusdescribed the invention, what I claim is 1. A device of the class described, comprising two doors, two tracksarranged upon the same horizontal plane, a set of rollers positioned for movement upon each of said tracks, side strips in separate ones of which said rollers are journaled, upper tracks positioned for movementupon each :set of rollers, yoke frames. carried by said upper tracks and one of said doors suspendedfrom each of said frames, connecting means between the rearward one of said upper tracks and the forward set of connecting strips, stop pins outwardly projectingadjacent the ends of said last named strips and a stop carried by the forwardly positioned one of said upper tracks and adapted for engagingsaid pins when the doors are completely opened or closed. 7

2. A device of the class described comprising parallel tracks, a. roller carrying frame upon each of said' tracks, means for suspending a separate door upon the frame 2 of each track, meansfor shifting one of said doors upon a movement of the frame for the other door, and means carried bysai'd last named frame adapted for limiting the movement of said other door atits extreme'open;

and closed position.

, 3. A device of the class described comsaid track, means connecting said frame and Signed at the city of New York, in the the door of less speed adapted for actuating county of New York, and State of New the latter upon a movement of said frame, a York, this 23d day of May, A. D. 1912.
