FASTENING DEVICE.

Specification of Letters Patent.

Patented Mar. 9, 1920.

To all whom it may concern:

Be it known that I, HENRY A. STEARN s, Jr., a citizen of the United States, residing at l/Voonsocket, in the county of Providence and State of Rhode Island, have invented.

new and useful Improvements in Fastening Devices, of which the following is a specification.

This invention relates to a fastening device for doors, covers and the like and has for its object to provide a device of simple construction which ordinarily serves the purpose of a latch for use upon doors of light construction such as for example screen doors, but which may also serve as a means of locking said door to prevent the opening of the same from one side thereof.

The invention contemplates a novel means of operating the latch from the outside of the door, said means constituting in efiect a key, the removal of which renders it impossible to open said door without forcing the same.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings:

Figure l is a side elevation of my i1nproved fastening device, the same being illustrated in connection with a door which is shown in section.

Fig. 2 is a plan view of the fastening device, the door and. door casing being illustrated in horizontal section as taken on the line 22 of Fig. 1.

Figs. 8 and 4 are side elevations similar to Fig. 1, illustrating two other embodiments of my invention.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, Figs. 1 and 2, 5 represents a door and 6 a door casing. To the inner side of the door 5 are fastened two similar brackets 7 and 8 having sides 9 and 10 respectively arranged in parallel relation to each other. A latch 11 is pivotally mounted at 12 upon the brackets 7 and 8 between the parallel sides 9 and 10 of said brackets. This method of mounting the latch 11 gives added stability to said latch.

The latch 11 has formed upon the inner end thereof a stop 13 which is adapted to engage the door 5 and thereby limit the upward movement of the outer end of said latch. A spring 1 1 is fastened at one end to the latch 11, its other end being fastened to the door 5. A staple 15 or other suitable catch is fastened to the door casing 6 and .when the door is in its closed position the spring 1 1 will cause the latch to engage said catch at which time a projection 16 suitably formed upon the outer end of said latch will prevent the opening of said door.

As a means of disengaging the projection 16 of the latch 11 from the staple 15, a thumb piece 17 is formed integral with the outer end of the latch 11. By pressin downwardly upon the thumb piece 1* against the tension of the spring 14, the

projection 16 may be disengaged from the staple 15 whereupon the door 5 may be opened.

The latch 11 is operated from the outside of the door by a rod 18, one end of which has screw-threaded engagement at 28 with a lug 19 fast to the latch 11. The rod 18 extends downwardly from the lug 19 and projects through a slot 20 provided in the door 5 terminating with a handle 21 fast thereto upon the outside of the door. The rod 18 passes through the door 5 at an angle to said door, the slot 20 in said door being of sufficient size to allow for the movement of the latch 11 together with the rod, as illustrated by the dotted line position i in Fig. 1.

The lug 19 is provided with a countersunk recess 22 which acts as a guide for the end of the rod 18 when said rod is bein inserted in the screw-threaded hole 23 of the lug 19 from the outside of the door 5.

The operation of my improved fastening device is as follows: If it is desired, by a person who is upon the same side of the door as the latch, to open the door, the same may be accomplished by pressing downwardly upon the thumb piece 17 thereby disengaging the projection 16 from the staple 15 whereupon the door 5 may be pushed open in the usual manner. If, however, upon the other hand the person is upon the opposite side of the door from the latch, the handle 21 upon the outer end of the rod 18 may be pulled thereby also disengaging the proj ection 16 from the staple 15 against the tension of the spring 14-, whereupon said door may be pulled open from the outside. If it is desired to make it impossible to open the door from the outside thereof, the rod 18 may be disengaged from the lug 19 by unscrewing said rod 18 from said lug and removing the rod 18 from the door and placing the same in the pocket. When it is again desired to open the door from the outside thereof, the rod 18 is inserted through the opening 20 in the door and shoved upwardly. As the end of the rod approaches the lug 19 it will engage the inclined sides of the countersunk recess 22 and will be guided by the same into engagement with the screw-threaded hole 23, whereupon the door may be again opened from the outside thereof.

In Fig. 3 I have illustrated a modified embodiment of my invention. In this form the only difference is the elimination of the spiral spring 14: and the substitution of another type of wire spring, as illustrated at 24:, which is mounted upon a stud 25, which acts as the pivot for the latch 11. One end of the spring 24k engages the underside of the bracket Tat a, the spring is then coiled around the stud 25 and its'other end engages the underside of the latch 11 at Z), thereby always tending to force the outer end of the latch 11 upwardly and into engagement with the staple 15.

In Fig. 1 another embodiment of my in vention is illustrated in which a flat spring 26 is mounted upon a stud 27 which forms the pivot for the latch 11, said flat spring 26 engaging the underside of-a pin 28 or other suitable projection fast to the latch 11, thereby tending to force said latch upwardly into engagement with the staple 15.

The operation of each of theseembodiments of my inventionis exactly the same as that previously described in connection with Figs. 1 and 2;

Having thus specifically described my invention what I claim and desire by Letters Patent to secure is: c

1. A fastening device for doors and the like having, in combinatioma pair ofbrackets adapted to be fastened to a door, said brackets being provided with parallel ad jacent sides, a latch pivoted to said brackets between said parallel sides, a catch adapted tobe fastened to a door casing, means to cause said latch to engage said catch when said door is closed, means integral with said latch adapted to limit the upward movement of the outer end of said latch when said latch is not in engagement with said catch, a lug fast to the outer end of said latch, and a rod detachably fastened to said lug and constituting'a key and adapted to project downwardly therefrom and through said door at an angle thereto, whereby said latch may be operated or said rod may be detached from or connected to said lug from the other side of said door from that to which said latch is fastened.

2. A fastening device for doors and the like having, in combination, a latch adapted to be pivotally fastened to the inside of a door, a thumb piece integral with said latch, a catchadapted to be fastened to a door cas ing, means to cause said latch to engage said catch when said door is closed, means to limit the upward movement of said latch when said door is open, a lug fast to the outer end of said latch, -a rod detachably fastened to said lug and constituting a key and adapted to project downwardly there from and through said door at an angle thereto, whereby said latch may be operated or said'rod may be rotated to be detached from or connected to said lug from the outside of said door, and means to guide the end of said rod into said lug when said rod has been disengaged from said lug.

v Inltestim'onyv whereof I have hereunto set my hand in presence of two subscribing witnesses.
