"To "ULZZ fwihom "it 1n-"ai 'concer/'niy yBe itknowiithat I, ilihywaiii) JOHNSON,

vafcitizen of -the zUnited States, 'and resident of fAxtell, infthecounty of Iea'rney 'and State of Nebraska, "have inventedcertain new and luseful vIniprov'einieiits in Locks, `of which fthe *following isa specification.

.Mv present *invention relates to ja lock-or Alatch ifor "doors'fof either the swinging 'or 'sliding type. j y The Iprincipal vobject 'ofthe |invention *is the lip'rovisionof means asd-above which *may be used'temporarily asa la't'clrto retain the door fiircl'osed position, or fas aA Alock `to ghe opened only by one having knowledge'of its operation. i Another kimportant object of the inven- 'tionis' the provision ,of apositively operated mechanism -which will be #ei'licient in operation and of sturdy construction.

To this end n'iy invention includes a i hooked keeper which projects through the stationary wall, with which 'a door carried bolt engages. i pushed in toward the wall to locked position which causes it to straddle the bolt the enlarged end of which prevents withdrawal therefrom. The hooked. `keeper automatiy.cally remains in locked position until the lockingmeans is released, as willr be more fully described. In addition to the locking keeper, an additional non-locking keeper 1s provided to temporarily retain the bolt iny pi'oxin'iity thereto` when it i's not desired to lock the door.

I have illustrated in the accompanying drawings one satisfactory forni of appara-l tus, but it is to be understood that I do not wishr to be limited thereto, as this is simply illustrative to exemplify the principle involved. Y

Iii these drawings n Figure 1 is a. view showing iiiy device iii use. f y A 2 is a plan View, partly in section. (Fig. 3 is a side elevation.

Fig. 4f is a view on the line f1-fl of Fig. 2.

Referring now with particularity to the drawings, I have shown a. wallr at 1 which represents the wall upon which the door 1s v to close in either a sliding or swinging inan- A Cw ner. Attached to the inside of the wall is a plate 2 which carries a keeper guide 3 composed of plates having parallel portions 4 riveted together as at 5, and right-angular f portions 6 secured to the plate 2 as by rivets The hooked keeper may be 1.924. Serial. N0. 705,058.

7. Suitable reinforcingineaiis, such as strips S, may be provided to `streng'gthenfthekeeper aide 3. A keeper'Q is' provided'of substantial lproportions, which is adapted to project through an aperture 10 "in *the wallwl, the projecting 'end of the keeper 'terminating `in a hook 11vfor apurpose inorefully hereinafter described. The" other end of thekeeper lis lprovided with'ears 12 on each side'therejection v'15, preferably integral witht-he keeper 9, projects above the top of the platesr foriningthekeeper guide 3. The upper ex- 'treinity of the portion 15 is provided 'with an aperture 16 to which is secured one end of a coil spring 17. The other end of the spring 17 is secured to the plate 2 in any suitable manner.

An angular spring element 18 secured to the plate 2 has a` portion thereof bearing against the angular side 1-1 of the ears 1,2

on the keeper 9. That portion of the spring relement 18 just referred to is also provided with an eyelet 19 to which is attached a release wire 2O extending to any desirable location remote from the lock.

The door which cooperates with the wall 1 is illustrated at 21, to which is attached in a i'evolvable manner a bolt 22 having an enlarged head 23.

The operation of the device'is as follows: l

If pressure is putonthe release Wire 2O the spring element 18 is pulled away from the ears 12, which causes the end of the element to clear the extreme face 13 of the ears 12 with the result that spring 17 is allowed to function and causes the keeper to project through the aperture 10 in the wall to any desired extent, determined by the slot 24C` in the plates forming the keeper guide. In this position the door is then inade to approach the Wall and the bolt inay then be revolved so as to fall within the'hooked end 11 of the keeper. If it is now desired to lock the door inthis position, pressure may be exerted along` the axis of the keeper 9 against the tension of the spring 17 so that the ears 12 clear the end of thespring ele.- ment 18 which snapsl against the keeper back of the rightangular face 13. At this position the end of the hook 11 is within the aperture l in the Wall and the bolt cannot be removed from the hook, and the door is securely locked in closed position. il guard plate may surround the keeper 9 and the aperture l0 through which it projects on the outside of the door to prevent the bolt from being forced from the hook.

As a temporary latch the hooked keeper 9 may remain in a projected or unlocked position and the bolt 22 on the door 21 swung over to engage a temporary keeper 26 having a slot 27 therein. This slot 27 Will electively prevent removal of the headed bolt therefrom accidentally. although this mechanism serves merely as a latch. j

I contemplate if for instance the lock is used on a barn door, extending the release Wire 20 to a point outside of the barn and away from the door so that the-device requires no key, but the keeper may be released by pulling on the Wire 20, the location of Which will only be known to one authorized to enter the barn or other housing.

Having thus described my invention, what I claim is v l. In combination a wall, a lock mer-,hw nism attached thereto, including a hooked keeper penetrating said Wall and at right angles thereto, and spring means to project said keeper to the outside of said Wall, lugs on said keeper, and spring retaining means adapted to engage said lugs and rendering ineffective said keeper projecting means.

2. In combination a Wall, a lock mechanism attached thereto, including a hooked keeper penetrating said Wall and at right angles thereto, a door, a swinging bolt carried thereby, said bolt slidably engaging the hooked end of said keeper.

i 3. In combination a Wall, a lock mechanism attached thereto, including a hooked keeper penetrating said Wall and at right angles thereto, a door, ak swinging bolt carried thereby, said bolt slidably engaging the hooked end of said keeper, With an additional keeper adapted to engage said bolt to ret-ain door and Wall together when the hooked keeper is in its outermost projected position.

In testimony whereof, I aiiiX my signature.

EDWARD H. JoHNsoN.
