LATCH FOR SLIDING- DOGRS.

Specification of Letters Patent.

Patented Sept. 2, 191

Application filed June 14, 1919. Serial No. 304,181.

To all whom it may concern:

Be it known that l, WILLIAM JULEN NEL- SON, a citizen of the United States, residing at Brandon, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Latches for Sliding Doors, of which the following is a specification, reference being had ond sliding door, or to a jamb of the door opening, for holding the door closed.

The invention further aims to provide a latch of this character, the hasp or latch member of which may be actuated from either side of the door, to disengage it from the keeper.

The invention further aims to provide guiding means for the hand grips'or grasps, as they are moved, when being independently movable with relation to the other, which may be pulled inwardly to actuate the former grasp or grip.

lVhile the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure l is a view in elevation showing a pair of sliding doors or closures, one of which may be, if so desired, interpreted as the jamb of the door opening.

Fig. 2 is a perspective view of the forward edge of a sliding door or closure showing the improved latch mechanism as applied.

Fig. 3 is a horizontal sectional View on line 3-3 of Fig. 1.

Fig. 4 discloses detail views of the keeper, and the means to which the keeper is connected.

Fig. 5 is a detail perspective view of a portion of the plate 17 showing the ll-shaped lug 18.

Referring to the drawings 1 and 2 designates opposite sheet metal plates, which are secured by screws or the like 2, to the inner and outer faces of the door or closure, adjacent its free edge. These plates 1 and 2 at oneof their ends are provided with lateral flanges 3, which overlie each other, and one of which overlies and engages the edge of the door or closure. These plates constitute means for supporting the latch mechanism.

Secured to the outer plate 1, as shown at at, are bracket plates 5, through the lateral parts of which the pivot bolt 6 is secured, by means of a nut 7. Pivoted upon the bolt 6 is a hand grip or grasp 8, which is angular as shown, and carries a laterally extending ear 9 provided with a pin 10. This pin 10 extends through a'slot 11 in the plate 1, and in surrounding relation to the pin and interposed between the ear and the plate is a coil spring 12, thereby so tensioning the hand grip or grasp as to hold it in its outermost position as shown clearly in Fig. 2.

The end of the grip or grasp opposite where it is pivoted isbent to form the right angle portion 13, which protrudes through the opening 14 in the plate 1. This opening 14 on its upper and lower edges is provided with inwardly turned flanges 15, which enter the opening 16 through the door, thereby not only constituting guides for the right angle extending portion of the grasp or grip. but also constituting wear plates. Carried by a portion of this right angle part of the grip or grasp is a plate 17 the inner end of which is provided with a lateral F-shaped lug 18. The opening in the door, which is bound by the flanges of the opening in the plate 1. is large enough to permit of the free movement of the portion 19 of the right angle part, so that the latch or hasp lug 20 (which is carried by the portion 19) can move far enough inwardly as to be disengaged from the keeper.-

The plate 2 at one end is provided with an opening 22, and secured to the face of the plate 2 adjacent the inner face of the door or closure is an arched or til-shaped plate 23,

lill

This plate may be riveted or otherwise secured to the plate 2 as shown, and the arch of the plate 23 enters a cavity or recess formed in the door proper. A second hand grasp or grip 2% is provided, and one .of its ends is pivoted upon a pin 25, which is mounted transversely of the arch of the plate 23, and this grasp or grip has a lug 26. A spring 26 is interposed between the last mentioned grip or grasp and the inner face of the arch of the plate 23, and is in surrounding relation to the lug, thereby holding the hand grip or grasp normally in the positions as shown in Fig. 3. The other end of the hand grip or grasp has a lateral extension 27, the greater end portionof which is slotted as shown at 28 and is curved, so as to permit free movement of the grip or grasp. This lateral extension 27 passes through an opening 29 in the plate 2. This opening registers with a correspondingly ositioned opening in the plate l. The opening 29 is also provided with inwardly extending flanges 30, also acting as guides and wear plates. The slot'in the lateral extension 27 receives the lateral T-shaped lug of the former grip or grasp, so therefore it will be seen that when the hand grip or grasp adjacent the inner face of the door or closure is pulled inwardly, the outer grip or grasp will-be likewise moved, thereby disengaging the hasp or latch member from the keeper. The outer hand grip or grasp may be moved inwardly, to disengage the latch or hasp from the keeper, without operating the hand grip or grasp adjacent the inner face of the door.

The keeper 31 comprises an angular plate 32, which is secured by screws or the like to the edge of an adjacent sliding door or to the edge of the jamb of a door opening,

. preferably the latter. This angular plate 32 has a vertical slot 3-1, and the keeper proper comprises a plate 35, which has a slot 36 for the reception of the latch or hasp of the outer grip or grasp, to hold the door latched. The latch or hasp consists of an angular metal strap secured in place to a part of the angular portion of the outer grip or grasp, and is adapted to receive a padlock or other locking means, that is after it has passed through the slot in the keeper proper in order to lock the door. The keeper plate proper is provided with an additional slot 37, which is disposed so that when the keeper plate proper is fastened to the angular plate, the slot 37 'will be disposed at right angles to the slot in the angular'plate. A suitable bolt 38 including a nut engages through the two slots, so as to clamp the keeper plate to the angular plate. VVher ever the angular plate is secured. either to a; sliding door or to the janibedportion of the door opening. the portioiito which it is secured is recessed, so as to permit of the reception of thehead of the bolt that secures the keeper plate to the angular plate. The keeper plate proper may be adjusted toward and from the latch or hasp or may be adjusted vertically, and by this adjustabihty of the keeper plate proper, the keeper plate may be arranged to accommodate itself to the sagging of the door, or the separation of the meeting edgesof the door or the meeting edge of one door relatively to the edge jamb of the door opening.

The invention having been set forth, what is claimed as new and useful is:

1. In a latch mechanism for closures, the combination with mounting plates secured to the inner and outer faces of the closure and provided with registering openings, of a. pair of hand grips or grasps pivotally mounted upon said plates and being movable in a horizontal plane, said hand grips or grasps having a sliding connection with each other, through said openings and through the closure, one of said grasps or grips having a latch -or hasp engaging through one of the plates, and a keeper to receive the latch or hasp.

, 2. In a latch mechanism, the combination with holding plates secured to the opposite faces of the closure, of a keeper either secured to a second closure or to the jamb of an opening, a latch or hasp to engage the keeper, and opposing members movable in a horizontal plane relatively to the closure, one carrying the latch or hasp and being operable from one side of the closure, the other having a loose connection With the former and being operable from the opposite side of the closure for operating the hasp or latchto disengage it from the keeper.

3. In a latch mechanism, the combination with holding plates secured to the opposite faces of the closure, of a keeper either secured to a second closure or to the jamb of an opening, a latch or has to engage the keeper, and opposing mem ers movable in a horizontal plane relatively to the closure, one carrying the latch or hasp and being operable from one side of the closure, the other having a loose connection with the former and being operable from the opposite side of the closure for operating the hasp or latch to disengage it from the keeper, and spring tensioning means for both members to hold them in normal positions.

4. In a latch mechanism, the combination with a closure having an opening near its edge, of a pair of plates secured to the opposite face of the closure and having flanges overlying each other and engaging the edge of the closure, thereby covering the opening, said plates having guide flanges extending into'the opening of the closure. a keeper adjustably carried by a second closure or the jainb of the door opening, a hasp or latch to engage said keeper, opposing members pivot- 10 tion wit ally mounted upon said plates and being operable through. the opening of the plates and guided by the flanges of said openings, oneof said members carrying the latch orhasp and being movahle in a horizontal plane relatively to the closure to disengage the haspl opening of the closure, whereby either of said members ma be actuated to disengage the hasp or latch rorn the keeper, and spring tensioning means for the opposing members.

In testimony whereof I hereunto afiix my 15 signature in the presence of two witnesses.

I WILLIAM JULEN NELSON.
