III wil I! Patented June 17, 1941 TED STAT E. S "PAT E N T OF FICE 2,246,344 ms'rsNfNe MEANS Arthur J. Calderwodd, Traer, Iowa Applicatibn February 1a, 1939, Serial No. 256,084

2 Claims. 1 ("01. 292--62) This invention relates to a fasteningrneans and 'hasp-articular relation to a fastening means suitable for fastening doors and like closures in tight engagement with the, wall, door jamb, window frameyorfother opening s'ought to be closed.

It is among the objects of my invention to provide [a fastening means for doors and the like which will hold. the, dooror other closure in tight engagement with the walls of the opening sought to be closed.

Another object of my "invention is to provide a device whichyvillhold a; door tightly closed under ordinary conditions but 'w'hichwill spring to a certain extentw'ithout injury underunusual H strain or forces.

Anotherobjct of my invention is q mne a fastening means whichis protected from snow, ice and the elements, and which may be so located that it is'sp'aced from the groun d "so that it will not become clogged w'ithsnow andice.

Another object of my invention is to provide a device which ma be locked in closed position.

Still another object of my invention is to provide a fastening means which may be reversed right or left as desired for use at the right or left end of a door.

Other and further features and objects of the invention will be more apparent to those skilled in the art upon a consideration of the accompanying drawing and following specifications, wherein are disclosed several exemplary embodiments of the invention, with the understanding, however, that such changes may be made therein as fall within the scope of the appended claims, without departing from the spirit of the invention.

In said drawing:

Figure 1 is a view, partly in elevation and partly in section, of a device constructed according to a preferred embodiment of my invention.

Figure 2 is a View in perspective of the device shown in Figure 1 as it appears when in use, and

Figure 3 is a view in perspective of the device as it appears: from the outside of the door.

Figure 4 is a view in perspective of a device constructed in accordance with a modified form of my invention.

Referring now to the drawing, and particularly to Figures 1 and 2 which illustrate a preferred embodiment of my invention, I preferably use a jamb plate In recessed or countersunk into the door jamb H, and having an outwardly extending fiange l2 thereon. In the embodiment of my invention here shown, I use stop members in the form of small triangular plates [3 and i4 which are mounted at the top and bottom of the jamb plate l0 and, within the angle formed by the jamb plate and the flange. These triangular plates: I3 and I4 serve to prevent the finger I5 from turning oif of the plate flange either at the top or at the bottom. t

The jamb plate is provided with lugs ll which are placedmidway between the top and bottom of the plate, and have openings therethrough for the insertion of a slidable bar l8, said bar being so mounted that when it is in the closed position the end thereof abuts against the flange I2 and extends into the arc of travel of the rotating finger I6.

Placing the bar I8 in the center of jamb plate l0 will permit the door fastener to be used either in a right or left handed position inasmuch as two recesses are provided for finger 16, In this manner the-finger I6 is locked in position, and it is then impossible to open thedoor from the outside.

The finger I6 is turned by means of shaft l9 extending through the door and through the outer plate 21], and is turned by a handle 2| at the end of the shaft.

The shaft I9 is surrounded by a coil spring 22 which abuts, at the outer end, against a washer I: and pin [91) which holds the washer in place, and at the inner end bears against the inside of plate 23. The plate 23 is countersunk into the door 24 and is notched or recessed to receive the finger l6 when the latch is in open position.

The spring 22 biases the shaft l9 outwardly so that the finger I6 is biased against the inner wall of the fiange l2 when the finger is engaged, The spring 22 serves two purposes, one of which is to hold the hook or finger IS in place on the plate [2, and the other of which is todraw the door tightly against the jamb.

The flange [2 is preferably made with indentations or recesses I211 and I21) to help retain the finger IS in the locked position.

The modification of my invention as shown in Figure 4 utilizes a T head bolt instead of the finger IS in the other embodiment. The T head bolt is adapted to operate in the same manner except that a slotted opening 21 is formed in the flange [2 through which the bolt head is inserted before being turned. When turned the bolt head is drawn inwardly by means of the spring against the flange l2. The head 26 of course bears against the plate at two points instead of one, as in the case of the L-shaped finger.

The flange is preferably recessed laterally, as

shown at 28, to receive the head and prevent it from Working out of the locked position.

It is apparent that to operate the lock shown in Figure 4 it is necessary to bring the bolt head into position opposite the slotted opening 21, then press inwardly on the handle and turn.

The device which I have described not only operates as a simple, inexpensive and effective latching and locking means, but also serves to hold the door tightly against the jamb. If the door is pushed outwardly from the inside the spring will take up the first shock, and if continued outward movement of the door occurs, the handle 2| will strike the outer plate and prevent the spring 22 from bottoming.

A further advantage of my device over the conventional bolt-type lock arises from the positioning of the base plate. When an attempt is made to open a door utilizing my device, a direction of force against the base plate would be at right angles to the screws which hold it in place, whereas in the conventional device the direction of force would be parallel to the fastening means. For this reason it is more difficult to force a door employing my device.

A device constructed according to my invention will draw a door or the like firmly against the jamb or other edge of an opening to be closed. The device may be located in spaced relation with respect to the ground so that it will not become clogged with snow and ice. The mechanism is protected from the elements. It can be used right or left as desired and may readily be locked in engaged position. The parts of the device may be constructed of inexpensive materials.

Although I have described several specific embodiments of my invention, it is apparent that modifications thereof may be made by those skilled in the-art! Such modifications may be made without departing from the spirit and scope of my invention as set forth in the appended claims,

I claim as my invention:

1. In a door fastener, a jamb plate, a portion thereof extending parallel to the door, a revolvable fastening member extending through an opening in the door and through a door plate, a means in the door plate to receive the fastening member, a portion of the fastening member bent over to form a hook adapted to be turned into position over the jamb plate, and a means for biasing the hook against the jamb plate comprising a spring on the fastening member within the opening in the door, one end of same bearing against the door plate, the other end adapted to be held in fixed relation to the fastening member.

2. In a door fastener, a jamb plate having a portion thereof extending parallel to the door, a revolvable fastening member extending through an opening in the door, a door plate mounted flush with the inner surface of the door, said door plate having a recess therein, said fastening member extending through an opening in the door plate and formed at its inner end to provide a latching finger adapted to be received flush within the recess of the door plate, a spring mounted around the fastening member and within the opening through the door and bearing against the door plate and against a protuberance on the fastening member to bias the fastening member outwardly, a cover plate having an opening therethrough for receiving the fastening member, a handle on the outer end of the fastening member, the fastening member adapted to be pressed inwardly against the action of the spring and be turned to engage the latching finger over the jamb plate, said jamb plate having a recess therein for frictionally engaging the latching finger, and pin means slidable in the jamb plate and adapted to prevent disengaging the latching finger from the jamb plate.
