Aug. 17, 1937. c. E. MATTlsoN DOOR OR GATE MECHANISM Filed May 27, 1956 aZcMa-Zzzzsan Patented Aug. 17, 1937 UNITED STATES OFFICE 2 Claims.

This invention aims to provide novel means whereby props pivoted to barriers, such as doors or gates, may be rendered peculiarly eiective and secure in holding the barriers closed.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains. v

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing:

Fig. 1 shows in elevation, a device constructed in accordance with the invention, and Figs. 2, 3 and 4 are sections taken, respectively, on the lines 2 2, 3-3 and 4-4 of Fig. 1.

The numeral I marks a support. A horizontally swinging barrier is designated by the numeral 2. The numeral 3 marks a like or similar barrier. The barrier 2 embodies a frame 4. The barrier 3 comprises a frame 5. The frames 4 and 5 are connected by hinges E to the support I. The barriers 2 and 3 are completed by panels 1, of any desired kind, secured to the frames 4 and 5. A handle 8 is secured to the inner edge of the barrier 2. A horizontal cleat 9 extends across the frame 4 of the barrier 2, near to the lower end of the barrier, and is secured to the corresponding panel 'l'. A cleat I0 extends across the frame 5 of the barrier 3, near to the lower end of the barrier, and is secured to the panel 'I of the barrier 3.

A hook-shaped rest II is secured to the cleat 9, near to the hinged edge of the door or barrier 2. A hook-shaped rest I2 is secured to the cleat I0 of the door or barrier 3, near to the hinged edge of the door. A screw eye I4 or the like is mounted in the cleat 9, near to the inner edge of the door 2. A screw eye I5 or the like is mounted in the cleat I0 near to the inner edge of the door 3. A vertical groove IS is formed in the cleat 9 of the door 2, near to the rest II. A pointed prop bar II Ais pivoted in the screw eye I 4. The prop I'I has a thread I8 extended inwardly from the lower or free end of the prop. A holding device I9, such as a nut, is engaged with the thread I8 of the prop I'I.

A prop bar 20 is pivoted in the screw eye I5. The props I'I and 20 are long enough so that they can hold the doors 2 and 3, respectively, in open position, by engagement with a floor or the ground.

A hook-shaped keeper 2I is mounted on the inner vertical part of the frame 4 of the door 2. A hook-shaped keeper 22 is mounted on the inner vertical part of the frame 5 of the door 3. The lower portions of the keepers 2I and 22 are in line horizontally.

A latch 23 is pivoted at 21 to the inner Vertical part of the frame 5 of the door 3 to swing vertically, toward and away from the panel 'I of the door 3. Near to its lower end, the latch 23 has a transverse horizontal shoulder 25. At its lower end, the latch is provided with a depending finger 26. Intermediate its ends, the latch 23 is offset as shown at 24.

The props I'I and 20 may be swung downwardly, to hold the doors 2 and 3 open, in an obvious way.

When the props I1 and 20 are not in use, and when it is not desired to lock the doors or barriers 2 and 3, the prop II is received by the rest II, the prop 20 being received by the rest I2. When the prop I'I is received by the rest II, the nut I9 is received in the groove I6 of the cleat 9.

When it is desired to lock the doors, the prop 26 is placed in the rest I2. The prop I'I is swung over and engaged with the keepers 2I and 22. Then the doors 2 and 3 are held, so that they cannot open. The nut I9 may be threaded along the prop II until the nut binds against the edge of the keeper 22. This serves to hold the prop I'I the more securely in place, to serve as a locking bar. Because the latch 23 is oiset at 24, the latch will clear the nut I9 when the latch is swung down. When the latch 23 is swung down, the shoulder 25 on the latch engages above the prop I'I, and the prop cannot be swung upwardly, out of the keepers 2i and 22. The finger 26 of the latch 23, engaging the prop I 'I prevents the latch from swinging clear of the prop Il. The pivot element 2l that carries the latch 23 is offset horizontally with respect to the prop I'I when the prop I'I is engaged with the keepers 2| and 22. The latch 23, therefore, acts by gravity to maintain a position in which the shoulder 25 of the latch is above the prop I 'I when the prop is in locking bolt position and engaged with the keepers 2I andl 22.

It is to be observed that the latch 23 not only engages the prop I'I, to maintain the prop engaged with the keepers 2I and 22 but also en- Cil gages the nut I9, so that the nut cannot back away, out of binding relation with respect to the keeper V22. Y Y

Having thus described the invention,V what is claimed is:

V1. In a. device of the class described, movably mounted barriers, keepers on the barriers,v a bar pivoted to one barrier and engageable with the keepers, `and a holding device movable on the bar and engaged with one keeper to hold the bar in both keepers.

2. In a device of the class described, movablyV mounted barriers, keepers on the barriers, a bar pivoted to one barrier and engageable with the l keepers, and a nut threaded on the bar and engageable in binding relation with one keeper, to hold the bar in both keepers,
