LATCHES FOR DOUBLE D OORS.

To all whom 'it may concern:

Be it known that I, BENJAMIN W. JOHN- soN, a citizen of the United States, resident of Grafton, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Latches for Double Doors; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to locks for double doors of cupboards, closets, windows, etc.

The objectof my invention is to provide a simple form of locking device by means of which each door of a pair may be latched independently of each other, and at the same time provide for the positive locking of one of the doors when the second door 1s closed and latched; and to these ends my invention comprises the novel features hereinafter set forth and claimed.

Referring to the accompanying /drawings Figure\1 1s a front view of Ia cupboard partly broken away with my invention applied thereto; Fig. 2 is an enlarged section on theline 2-2 Fig. 1; Fig. 3 is a like view to Fig. 2 showing t-he parts in different position; and Fig. 4 is a sectionA on the line 4-4 Fig. 2.

I have illustrated my invention in connection with a simple form of cupboard or closet in which the two doors 2 and 3 are in close relation with each other at the closing edges, and secured to the frame 4 is the shell or casing 5 which is held in place by means of the screws 6. Within the'casing 5 is the guide-way 7 formed by the metal-plate 8.V

Within the guide-way 7 are the latches 9 and 10. The latch 9 is secured to the bar 11 and the oppositel end of said bar passes through an opening 12in the latch 10. A spring 13 encircles the bar 11 and said. spring bears against the inner face of the latch 9 and the inner face of the latch 10. Stops 14 and 15 limit the outward movement of the latches 9 and l0.v The latch 10 has the tail-piece 16 which acts as a guide for` the latch 10 within the casing.

Secured to the door `2 is the catch 17 with the notch`18 and a like catch 19 is secured-io the door 3. When the door 2is closed the catch 17 will slip by the latch 10 and the spring 13 will then act to force the latch guide-way 7 of the Specification of Letters Patent.

Application led January 13, 1911.

the bolt-rod 11 so that it will Serial No. 602,492.

come the act-ion of the latch 10.' In like,

manner the door 3 maybe closed and latched by the latch 9. However, t-he latching of the door 3,`in the present form of my invention, also acts to positively lock the door 2, for the movement of the latch 9 by the catch 19 will act to move the bolt-rod 11 which is secured to the latch 9 to the left, and the end of said bolt-rod will enter the notch 1-8 of the catch 17 and thus positively lock the door 2, so that the door 2 cannot be opened without first opening the door 3. However, if desired I may dispense with the positive locking of the door 2 by shortening not engage the notch 18 of thc catch 17, and in that case the closing of each door will simply latch each door, so thatthey can be opened inde pendently of each other. In some cases where it is not found necessary to lock the door sections thisconstruction in which the positive lock is omitted will be found desirable, and I provide a double latch in which the door sections are latched entirely independently of each other.

It is apparent that my invention may be applied to numerous forms of double doors, and the location of the device may be varied to suit different conditions, as in some cases it may be desirable to locate it at the bottom instead .of t-he top of the door or window frame, and in solre cases the doors may be separated by an intervening strip, all of which different modes of application are included within my invention.

What I claim is:

l. In a fastener for double doors, the combination with a suitable casing adapted to be located in t-he door frame, of a pair of latches .therein movable longitudinally in opposite directions to latch and unlatch, a catch adapted to be applied to each door section to engage one of said latches, and means coperating with said latches and catches whereby the door last closed will cause the door lirst closed to be positively locked. v
