SWIVEL-HANGER FOR DOORS.

Specification of Letters Patent. Patented June 15,1920.

Application filed February 12, 1920. Serial No. 358,035.

To all whom it may concern: 7

Be it known that I, THOMAS V. Place, a citizen of the United States of America, residing atAshland, Ohio, have invented new and useful Improvements in Swivel- Hangers for Doors, of which the following Fig. 3 is a similar view showing the door open.

Fig. 4; is a front elevation relatively enlarged of the hangerand'hold back.

Fig. 5 is an edge view of the parts shown in Fig. 4 looking from right to left.

- 'Fig. 6 is a perspective view of certain details.

Fig.7 is a side view of the door stop.

' 1l represent the top and sides of a door. casing. 23 represent two doors. The door 2 is hinged to the door casing 1 so as to swing outwardly. The door section 3 is hinged to the door section Qso as .to swing inwardly relatively thereto (see Fig. 8). 4 is an overhead track from which the door section 3 is supported by means of a hanger receive support from the track f through the medium of the hanger. The hanger is of the swivel type, that is to say, it comprises the'wheel carrying frame 5 having a swivel connection with a bracket 6, the bracket being suitably secured to the door by means of screws, bolts or otherwise. It follows that as the door sections are moved from the closed position, Fig. '1, to the open position shown in Fig. 3,,the doors. will partake of a rotary movement relatively to the wheel carrying portion of the hanger. It also is apparent that ifthe end of the track is curved or offset as shown in Figs. 2 and 3, the wheel carrying frame of the hanger will partake of a rotary movement relatively to the door. It is apparent that as the doors partake of this compound swinging and sliding movement, it is only with the greatest difficulty that a simple and effective-stop and hold back mechanism may be employed in connectionwith said doors. In my invention, instead of associating the hold back connection with the doors, I associate it with the track and hanger so that no matter what may be the location of the stop itself, the hold back device will always be so positioned relatively to thestop that it may be interengaged therewith for the purpose of holding the door open. By looking at Fig. 3, it will be apparent that unless an effective hold back means is provided, a draft of air creating pressure against the left hand side of the door section 2, would tend to move the doors into the closing position, which would endangerthe safety of a vehicle being backed out of a building equipped with'such doors. Accordingly, to

guard against this possible danger and in jury, I have provided the hold back mechanism referred to and I have so constructed the same that it may be adjusted to any de sired position and may be reversed so as to be associated with doors opening either to the right or, left.v The stop, itself, comprises a C-shaped member 7 which is arranged to slide on the'track 4; and which may be locked in any position thereon by a set screw or bolt 8. Extending outwardly from the member 7 is an offset shoulder or abutment 9 through whichthe set screw or bolt passes and which offset constitutes the stop, per 86. When the stop is adjusted on the track 4i at the desired position and the door is opened, the edge of the wheel carrying frame 5 will eventually strike said stop, as shown in. Fig. 3, and stop the further opening of the door. On the upper and lower edges of the abutment 9 I form flanges 11 is a latch, pivoted intermediate its "length on a stud 12 carried by the wheel carrying frame 5. One end of this latch is provided with a beveled hooked nose 14, while the other end is provided with a short arm to which a chain 15 may be attached so that by pulling down on the chain the hooked end of the latch may be lifted. 1617 are stops on opposite sides of the wheel carrying frame which limit the rocking movement of the latch in both directions. 18 is a cotter pin which constitutes one conven ient means of holding the latch on the stud 112-. The hooked end of the latch is preferably weighted by making said hooked end suiiiciently bulky, as shown. This weighted end normally rests on the stop shoulder 16 so that the bevel side of the latch will, when the door is opened, engage the upper flange 10 of the stop and be lifted thereby so as to drop back oi the same in the manner shown in Fig. 6, thereby holding the door opened until manually released, thus preventing any accidental closing, or partial closing, of the door by drafts or otherwise. By mounting the latch on the roller carrying frame, it is apparent that the latter will always serve to guide the latch directly to the stop so that it may he lifted thereby to engage therewith for hold, back purposes. Illanifestly, if the hold back latch were carried by either of the door sections, special means would have to be provided to guarantee the proper inter-ongagement of the same with any suitable abutment shoulder, and this would have to be varied according to various positions of adjus ment. In the present instance, it matters not where the door stop is placed upon the track, the latch will always be guided properly into inter-engagement therewith by the wheel carrying frame 5. I provide a rib 10 on the upper and lower side of the stop so that this stop may be reversed in its position on the rail or track It will also be noted that by removing the cotter pin 10, the latch may be reversed on the wheel carrying frame 5 thus adapting my invention to either a right or a left hand door structure.

It will be seen from the foregoing that my invention has particular utility in connection with door hangers in which one part of the track is oilset from the door casing o a greater degree thananother part. As hown in the drawings, that part of the track which supports the hanger when the door is closed is relatively close to the door casing so that the door when closed will stand in the proper position. On the other hand, that part of the track which supports the hanger when the door is open is offset from the door casing to a greater degree because it is obvious that the door lnmger itself will tend to move away from the plane of the door casing as the doors are folded back, the extreme outward movement occurring when it is desired to fold the doors back to an even greater degree than shown in the drawings, and for example, as far back will cause said doors to lie substantially parallel with theplane of the casing. In this latter event the door hanger will stand away from the casing somewhat more than the sum o1 the thickness of the two door sections. In such a construction, it is obvious that there would be great difiiculty in providing effective stop mechanism were it not constructed in the substantially new manner shown herein which permits the stop and hold back shoulder to be located anywhere on the rail irrespective of the degree of offset of that part of the rail where said stop is to be placed.

What I claim is:

1. In a door support of the type comprising a fixed supporting track and a door ing a fixed supporting track and a door hanger designed to ride thereon, a stop on said track, said door hanger comprising a bracket arranged to be secured to a door, a frame carrying a wheel designed to run on said track, a swivel connection between said frame and said bracket, a latch carried by the wheel carrying frame arranged to interlock with said stopon said track when the door to which the hanger is attached is open, said stop being adjustable on said track, said latch being arranged to engage said stop in its various positions of adjustment.

3. In a door support of the type comprising a fixed supporting track and a door hanger designed to ride thereon, a stop on said track, said door hanger comprising a bracket arranged to be secured to a door, a frame carrying a wheel designed to run on said track, a swivel connection between said frame and said bracket, a latch carried by the wheel carrying frame arranged to interlock with said stop on said track when the door to which the hanger is attached is open, said latch being pivotally mounted'on said frame and reversible relative thereto.

4 In a door support of the type comprising a fixed. supporting track and a door hanger designed to ride thereon, a stop on said track, said door hanger comprising a bracket arranged to be secured to a door, a frame carrying a wheel designed to run on said track, swivel connection between said frame and. said bracket, a latch carried by the wheel carrying frame arranged to interlock with said stop on said track when the door to which the hanger is attached is open, said stop being adjustable on said track, said latch being arranged to engage said stop in its various positions of adjustment, the connection between said frame and bracket being in the form of aswivel.
