2 Claims'.

The` present invention relates generally to locks for closures; and is more. particularly concerned with improvements in the. housing or casing for the lock parts.

The present application constitutes a division of our application Serial No. 23,426', filed April 27, 1948.

It is one object. of the present invention to provide in a lock structure of the character described herein a casing having sidey plates so arranged that they may be mounted on opposite sides of the door panel to conceal the lock mechanism, these platesA being, adjustable for mount.- ing upon door panels of varied thickness.

Another object is. to provide casing side plates for sliding door locks, which are provided with actuators permanently assembled as a part of the plate assembly, and so arranged that it will make a slip connection with a Fart ofthe lock actuatingv mechanism, so that no tools. screws, or additional parts are necessary for interconnecting the actuator with the lock mechanism. Moreover, the actuator is so arranged' that pressure thereon in' a direction to open the door will' act to release the lock member with respect to a keeper.

A still further object is to provide an improved casing side plate whichv is` readily adapted for themounting of different types of lock bar actuators. That is, a recess is provided in the. side plate in which there may be mounted a linger engageable button by which the lock bar may be shifted to locked and unlocked positions with re,- spect to the latch memben or a. key controlled lock actuating mechanism may be mounted in this recess, this mechanism including meansfor throwing the lock bar to locked and unlocked positions'. rlhus', a flexibility of mounting is. ob.- tained' without the necessity of providing different side plates.

Further objects of the invention will be brought v out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing preferred embodiments ofthe invention without placinglimitations on the scope of the invention defined in the appended.

Referring more specifically to Figs. l and 2 of the; drawings,l a lock enclosing casing as generally indicated at A is. mounted upon a rsliding door panel [EL this. casing containing a lock mecha- ',nism as generally. indicated at Bin Fig. 2. The

casing and' associated lock, is so mounted on` the vedge margin of the. door panel as to be moved into operative position with a keeper H mounted in a' projecting position on an associated door jamb l2.

The lock mechanism B will first be described. The parts of this. mechanism are mounted; and

supported in cri-operative relationship between a pair of' spaced frame plate members I-3 and' i3".

More specifically, the lock mechanism com.-

,prises a lock member le which is pivotally mounted for rotational movement; on a pivot member T5, this member being positioned between the ends4 of the lock member and having its ends supported' in the frame plate members I-i---l3` One end of the lock :member is provided with The opposite kend of the lock member is enygaged by one end of a leaf spring I8, which is anchored at its otherl end by flexing cver'in- 'tegrall-y formed projection lugs I9, and 20 carried by the frame plate member f3; This spring,

iviewed in Fig. 2',v acts to bias the lock member. i4

for rotational movement in a clockwise direction about' its pivot f5'. j I

The spring engaged end ci the lockzmembei` is 4operatively associated with a latch member 2| which is pivotally supported at one end for ro'- tational movement about a pivot 22 having its ends supported in the frame plate members |3-|3. The free end of the latch member 1s formed with an angularly deflected end pcrt1on 23 which at its outer end is formed with an abutment shoulder 24 and at its inner end carries a transversely extending actuating bar 25.

The actuating bar 25 projects on both sides of the latch member 2| and has its ends extended through notched openings 26 and 28 in the frame plate members |3 and |3, respectively. The actuating bar also forms an abutment shoulder which, together with abutment shoulder 24, is movable into the path of movement of the adjacent end of the lock member l for limiting rotational movement of the lock member at two positions, namely, a full line position, as shown in Fig. 2, and the dotted line position as shown therein. It will be observed that in the dotted line position of the lock member it, the entrance opening of the slot I6 is positioned in a keeper receiving position in which a U-shaped portion 21 thereof may enter the slot and engage against a wall 28 thereof. This wall 28 is initially inclined and when engaged by the keeper portion 21, results in rotative movement of the lock member to full line position wherein the hook |1 locks the keeper against removal from the slot I6, and the other end of the lock member will be latched by engagement with the abutment shoulder formed by the actuating bai' 25. It will be noted that the frame plate members i3 and |3 are provided with edge notches 29 and 2Q' respectively to receive the keeper portion 21.

The latch member is normally biased toward latching position by a leaf spring 36 having a. free end bearing against the latch member. This spring is anchored by flexing the other end portion around a spacer 3| between the frame plate members |S-|3 and engaging the end portion 32 back of a plate lug 33.

As viewed in 2, it will be observed that with the latch member in the full line position as shown, the lock member I4 will be locked so as to prevent disengagement of the keeper but that by moving the latch member to the dotted line position, the lock member is free to move under the action of spring 8 to its dotted line position in which the keeper may be withdrawn or the sliding door panel moved to open position.

As an additional feature, the lock mechanism further includes a lockingr bar 34 which is pivoted intermediate its ends on a pivot 35 for swinging movement. This locking bar has one end deformed to present a right angled shoulder 36 which in the full line position of theV locking bar coacts with a projecting arm 31 to lock the latch member 2| against movement to its unlatched position. However, it will be evident that if the locking bar 34 is moved to its dotted line position by applying pressure to its end 38 in a clockwise direction, as shown in Fig. 2, the shoulder 35 will be removed from restraining position with respect to the arm 31 so as to then permit manual movement of the latch member to released position with respect to the lock member |4 and also serve as an indicator of lockedunlocked condition of the lock.

The enclosing casing A will now be described. This casing includes a pair of side plates 39 and 39', adapted to cooperatively cover the surface openings of a cut-out 40 in the jamb engaging edge portion of a sliding door panel 0, as shown in Fig. 4.

One feature of the casing described herein resides in its being adjustable for variable thicknesses of panel closures, so that the same side plate may be utilized for door panels of different thicknesses, without the necessity of providing a plurality of interconnected side plates for accommodating various thicknesses of closure panels. This adjustability is accomplished by providing along the inner end marginal portions of the side plate, a rolled or turned over edge 4| in each case which terminates in an edge flange 42. These edge flanges are respectively provided with projecting wings 43-43 containing slotted openings 44. By disposing the wings 43-43 of the plate 3S and plate 39 respectively in position with the slotted openings in registration, movements of adjustment of the side plates toward and away from each other may be obtained.

The side plates are held in adjusted position by screws 44 which extend through an end plate 45 having its lateral margin seated cn the nanges 42-42 of the plates. These screws are threaded into overlapping lugs 46-46, carried by the frame plate members |3-|3, so that by this arrangement, the lock mechanism is supported between the side plates from the end plate The ends of the plate 45 contain aperturesI t1 for receiving securing screws for holding the end plate, these screws being indicated by the numeral i3 in Fig. l.

The end plate 65 is provided with an opening i9 for receiving the keeper therethrough, when the door is in closed position, and an opening 5D in which a finger may be inserted for pulling the door toward closed position. In order to limit the amountI of insertion of a finger into the opening 5G, and in order to protect it from contact with other portions of the lock mechanism, there is provided a cup-shaped shielding member 5| having upper and lower projecting wing portions 52-52, each of which contains a slot 53 for receiving a mounting screw. In the present instance, the cup-shaped member 5| is mounted by inserting the lowermost wing portion so that it will be held by one of the screws 44, and the other wing portions so that it will be retained in position by a screw 48.

Referring to Figs. 1, 4 and 6, each side plate is substantially of rectangular shape and contains in this instance a rectangular recessed portion 54 and a substantially circular recessed portion 55. On opposite sides of the recessed portion 54 the material is formed to provide parallel grooves or ledges 56-58 having in each case an elongate slot 51 formed therein.

An actuator 58 is slidably mounted for lateral movements within the recess 54, this actuator having end margins extending over the ledges 55, and right angled side margins 59 extending into the recess 54. This actuator may be variously constructed and connected in different ways, but for illustrative purposes has been shown as beingy secured to a carriage member 60 of substantially I-shape with its intermediate portion of channel shape as shown by the numeral in 6, this portion being secured as bv soldering or brazing 52 to the bottom surface of the actuator 58. The end portions 63 are iiat and are each deflected at their end margins to form a right angled flange 64, which extends through a slot 51 and has outwardly turned ends 85, by means of which it is held against removal from the slot. as shown in Figs. 1 and 7. The slot 51 thus limits the lateral movement of the actuator, and the channel portion 6| forms a slip joint connection for receiving an end of the actuating bar 25 therein, the

bottom of the recessed portion 54 being provided with an aperture 66 through which the end of the actuator bar projects. A spacer 61, as shown in Fig. 6, interconnects the recessed portion 54 of the plates 39 and 39', this spacer being connected at its ends by a screw 68 in each case to the bottom or" the adjacent recessed portion. The foregoing provides a unique method of connecting the actuator as a permanent part of the flush plate assembly and utilizes a slip connection with a portion of the locking mechanism, of such nature that no tools are required to make the connection.

Various arrangements are possible for accomplishing actuation of the locking bar 34 manually from one or both sides of the door, or through the agency of a key controlled means. As shown in Figs. 1, 2, and 4, a pin 69` is mounted in the end 38 of the locking bar, this pin extending transversely of the bar and having its ends extending through an arcuate slot 19 in each case into the recessed portion 55 of the side plates. The ends of the pin are provided with finger engageable buttons 'H which are substantially flush with the main surface of the side plates. The pin 69 is retained against shifting movement by a screw 12 or other suitable means. With this arrangement, the locking bar may be actuated to locked and unlocked positions from either side of the door panel merely by manually shifting the buttons 1|.

If desired, arrangements may be made to actuate the locking bar from only one side of the door, simply by not projecting the pin 69 through the slot 19 on that side from which it is desired not to operate the locking bar. However, for emergency operation from this side, it is the usual practice to indent the end of the pin 69 on this side, so that it may be shifted by the insertion of a pointed instrument through the associated slot into the indented end of the pin, and thus in emergency shift the locking bar.

Moreover, the unique construction of the side plates with the circular recessed portion 55 as illustrated permits use of a key cylinder controlled actuating means, as generally indicated by the numeral 'I3 in Fig. 7. Such means is of conventional construction containing a cylinder actuatable by a key 14, the key means including suitable mounting means which may comprise, as f shown, a threaded outer sleeve with which a. mounting nut 16 is operatively associated to mount and secure the key means with its key end mounted in the recessed portion 55 so as not to project beyond the surface of the associated ilush plate. The key means contains a cam arm 11 for engaging the pin 99 and thus shift the locking bar to locked and unlocked position, as desired.

From the foregoing description, it will be apparent that the present invention provides a unique and improved lock and casing assembly which is so constructed as to make it easily adaptable for variations in mounting positions, and particularly adapted for use with sliding doors.

We claim as our invention:
