This invention relates to locking mecha# nism for doors and more particularly to such mechanism wherein there are employed a releasable latch and an additional bolt as a *o night lock. p

One of the objects ofthe invention is to provide av mechanism of the above nature which is practical and efficient and capable of meeting the requirements yof use in a highly satisfactory manner. Another object is `to Y provide a devicer of the above vnature which is capable of a wide range of use `under varying conditions. Another 'object is to provide a device of the above nature which is simple 1'5 andy which" is capable ot being mounted in operative position with theigreatest conven.- ience and withouttheneed of undue alterations or'adjustments to meet varyingcondi-l tions.v Another object isto provide a device i 2O-of theabovenature ywhich* is strong and dependable. Other objects will be in part obvious or in part pointedout hereinafter."

The invention accordingly consists in the features of construction,combinations of ele- 5 ments, and arrangements of parts as will be exemplified in the structure to be hereinafter described and theis'cope of the applicationot which will ybe indicated in the following claims; A 4f Y f y In the accompanying drawings in' which is shown one of the-variouspossible embodi-y ments of this invention," Y Figure 1y is ay front-view of the lock mecha,- nism in operative positiomthe Vdoor vframe and parts of the mechanism being'brolen away to disclose the inner structure; Y

the door Figure 2 is anelevation viewing Jframe edgewise;

c Figure 3 is a perspective ofthe door frame portionshown in FigureQ; Figure 4 is a view similar to Figure 3 and showing the same locking mechanism applied to a door frame wherein the door kswings in the opposite direction, and Figure 'is a perspective of certain? parts of. the locking mechanism removed from the door frame. Y 1 f Similar referencechar'acters refer to similar parts throughout theseveral views of the drawings. i

p Referring now tothe drawings in detail and first tollligure l, there is shown a door 10 adapted to swing into a door frame indicated at 11 and against a stop 11a. The door frame 11 is recessed at 12 to accommodate axmetal casing J13 which ormsfa part of the looking mechanism. This casing 13 may be made conveniently of brass and in "the embodiment shown in the drawings it is l a cast1ng,lit belngunderstood that the casing might also be shaped lout of sheet metal.

ffidyacent the open outerend ot the casing 13 ismounted thereinr a member 14 which is Aadapted to receive and catch thel-atchl of the door 10 and thereby hold the'door closed.

able mechanism contained within the casing 13 whereby it may be moved, by control from i a remote point, to a position in vwhich the latch 15 is disengaged,ftherebypermitting opening ofthe door.

ln the embodiment of the latch-releasing mechanismshown in the drawings, the mem; ber ltispivotally mounted upon a vertical pin 16 and is urged by spring v17 to swing, in they direction indicated bythe arrow in Figure 3, into engagement with thelatch 15.

Two lever arms 18 are pivoted in thecasing 13l and engagewith the member v11i adjacent their outer ends through pins 19 projecting rom'thetOpand bottom ends of the'member l '14. The inner .ends of the lever 'arms 18 normally engage theedge of a plate-like ar-e matureQO'which is pivoted in the casingj13 and which is positioned, therein to be actu- 4This` memberlet is provided .with any suit-` ated by the jelectromagnet 21. Thev coils ofI lthe electromagnet are connectedthrough the bindingposts k22 to any suitable source of cur i rent'and thr'ough'aswitch which may be lothe urge of the spring 16 to a position in which the latch is enabled to slip by. It may be here noted that this releasing mechanism is not shown in greater detail since of themselves the specific features thereof are unimportant as relating to this invention.

The casing 13 is provided at its front end with right angle extensions 24 and 25 in plate form extending out vardly therefrom on opposite sides thereof; that is, whenfthe lnechanism is in position upon the door frame, one of these plate extensions projects upwardly from the casing 13 and the other projects downwardly therefrom.y The parts 24 and 25 preferably are permanently secured to the casing 1,3. They may be made integral with the casing if desired, or they may comprise a single integral plate secured to the casing 13, for example by welding, and the two parts of which are joined by a central portion 26, as best shown in Figures 2 and The parts 24 and 25 are adapted to rest fiatwise against the surface of the door frame 11, as shown and preferably the door frame is recessed to receive them. Screws 2,7 passing through the parts 24 and 2,5 into the door frame 11 serve to position and hold in place the entire lock mechanism of the door frame.

Referring again to Figure'l, the lock mechanism mounted upon the door 10 is provided with a bolt 2.3 in addition to the latch 15. This bolt is in the nature of al night lock and may be operated, for example, by a thumb knob on the innerside of the door and by a key from the outer side.

In some doors the night bolt 2-3 is positioned below the latch 11i, as shown in the drawing, and in other doors itis positioned above the latch. The locking mechanism employed upon the door frame herein disclosed is adapted to meet the requirements in either case. The plate parts 24 and 25 of the casing 13 are preferably substantially identical and each is provided with an opening therethrough which may receive a night bolt23. As shown in Figure 5, the part 24 is provided with the opening 28 and the part 25 is provided with the opening 29. r

These openings 28 and 29. are furnished with means whereby either one thereof may f be rendered operative or inoperative as desired. Removable metal pieces 30 and 31 are provided which `fit snugly int-o the respective openings 28 and 29. Preferably these metal pieces and the openings in which they fit are correspondingly tapered, lbeinglarger at the rear of the plate than at the front, so that the metal pieces are removable only from the rear. Thus when the device isk positioned against the door frame, the metal piece'whch is left in its opening 4is locked inposition therein by the 4door frame. `The metal pieces lare preferably :of the ,same thickness as the metal of `the plate parts into which they fit so that tbesurfaces are substantially flush.

Thus in the door frame shown in Figures 1, 2 and 3, wherein the night bolt is positioned below the latch, and wherein the door swings as indicated by the arrow in Figure 3 against the stop 11a, the piece 31 is knocked out so that the opening 29 in the part 25 is rendered operative to receive the night bolt, andthe piece 30 is left in position in its opening 28 effectively closing this opening and being locked in position by the door frame against which it rests. If the bolt of the night lock were above the latch in this door, the piece 30 would be knocked out to render the opening 28 operative and the piece 31 would be left in position.

Referring now to Figure 4, there is shown a door frame wherein the door swings against stop 11?) in a direction opposite to the direction of swing of the door in the preceding figures. In this instance the locking mechanism of the door frame is simply turned end for end, the part being now abovethe latchreceiving means and the part 24 below. If the night bolt is below the latch the piece is knocked out to render the opening 28 operative (as shown in yFigure 4) and the piece 31 is left in. If the night bolt were above the 'latch the piece 31 would be knocked out and the piece 30 left in place. It will be seen, therefore, that the locking mechanism is capable of fulfilling any requirement without being altered or adjusted and without re-.arrangement of any parts except for simply knocking out one of the metal pieces 30 or 31 according to the opening to be utilized. These metal pieces may be termed knock-outs.

From the foregoing it will be seen that there is herein vprovided a device which embodies the features of this invention and achieves the objects thereof including ad- Y vantages of great practical importance. The devices are preferably furnished with both the pieces 30 and lintact. The carpenter setting upthe locking mechanism has then simply vto knock out the piece not required in order to fit the mechanism to any conditions which may be met. The plate members 24 and 25 being permanently secured to the casing 13, full strength and serviceability is assured.

As many possible embodiments may be made of the above invention, andas many changes might be made in the embodiment above set, forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
