LOCK.
Application filed May 24, 1928. Serial No. 280,124.
This invention relates to locks, and more particularly to locks intended for use 1n connection with sliding or swingmg double doors or windows. lVall cabinets, and the like, are often provided with double doors that are mounted to slide behind the front wall of the cabinet so as to expose the door opening therein. tered in providing a lock for such doors, owing to the fact that they frequently warp or get out of shape, so that the lock bolt fails to function properly in looking the two doors to.
gether.
. The principal object of the present invention is to provide a simple, inexpensive and efficient lock for sliding or swinging double doors or windows having means for compensating for any unevenness in the doors caused by warping shrinking, sagglng or the like. Another object is to provide a lock of the charactor mentioned, wherein a pin cylinder lock mechanism is employed having a lock boll; mounted on the pin cylinder with a limited amount of lost motion thereon, whereby the pin cylinder may be rotated through a complete circle in locking or unlocking the lock, whereas the lock bolt is moved through an arc of approximately ninety degrees.
The invention further consists in the several novel features of construction, arrangement and combinations of parts hereinafter more fully set forth and claimed.
The invention is clearly illustrated in the drawing accompanying this specification in which- Figure 1 is a front elevation of fragments of a pair of sliding doors equipped with a lock embodying a simple form of the invention, one of the doors being broken out to illustrate the lock therein;
Fig. 2 is a detail horizontal section through fragments of the two doors showing the same closed, and illustrating the lock in locked position;
Fig. 8 is a vertical cross section taken on the line 33. of Fig. 2;
Fig. 4 is a perspective view of the lock bolt; and
Fig. 5 is a fragmental horizontal section through a cabinet equipped with a pair of sliding doors containing the lock.
Referring to said drawing. and first to Fig. 5, the reference character 6 designates a cabinet having a door opening 7 in its front wall Considerable difficulty has been encounadapted to be closed by a pair of sliding doors 8 and 9. Referring now to Figs. 1 to 4;, inclusive, the face plate 10 of the lock will be seen to comprise an angle shaped plate having one part 11 secured by screws to the rear side of one of the upright frame members 12 of the door 8, the other pa rt13 of the plate being dis posed in the edge portion of the door.
Rigidly connected with the part 13 of the face plate is the lock casing l t in which is rotatably mounted the pin cylinder 15 of an or dmary pin cylinder lock. A key 16 is pro vided for releasing the pins or tumblers of the lock and turning the cylinder to lock and unlock the lock.
The pin cylinder projects beyond the inner end of the lock casing 14L and upon said protruding end is mounted the lock bolt 17. Said lock bolt is loosely mounted on the pin cvlindcr, whereby the latter may be rotated wi lih respect thereto, and on the hub portion 18 of said lock bolt is an are shaped lug 19 having an arcuate extent of about ninety degrees. i 11 pin or other shoulder 20 secured .in or to the pin cylinder is arranged to engage with either end of said lug- 19 when the pin cylinder is turned for the purpose of rotating the lock bolt. The lock bolt is secured against axial movement on the pm cylinder between the lock casin and pin 20. i h
A spring 21 secured to the part 11 of the face plate has one end arranged to engage in a notch 22 formed .in the side of the hub 18 of the lock bolt when the latter occupies an upright or unlocked position to thereby yieldingly hold said lock bolt in its unlocked position until the pin 20 is forced into engagement with the lug 19 in moving the lock bolt into its locked position.
The shank 23 of the lock bolt extends from the hub portion 18 and is arranged to be moved into engagement with a keeper plate 24 secured to the front face of the door 9 by screws or the like. and said shank is provided on its end with laterally extending lugs 25 which are adapted to engage wit-lithe rear side of the keeper plate 24 to prevent the two doors from being spread apart laterally of each other when in their locked position. The part- 11 of the face plate is formed with a T- shaped notch 26 through which the lock bolt is moved from one side of the plate to the other and the keeper plate 24 is also provided with a T-shaped slot 27 through which the (ill look bolt is projected when looking the two doors together. It is understood that the doors are cut out to receive the operative parts of the lock. 7
hen in unlocked position, the lock bolt stands in a vertical position, as seen in dotted lines, in Fig. 3, whereby the two doors are free to be moved apart. Wishing to lock the doors together, the key is inserted into the lock and turned in the proper direction to swing the lock bolt down into engagement with the keeper plate 24, which position is seen in full lines in Fig. 3.
In order to remove the key from the lock, the key must be given one complete revolution and, consequently,- the pin cylinder must be rotated through a complete circle. At the commencement of the movement of the cylinder, the pin 20 occupies the position illustrated in Fig. 3, and during the rotation of the cylinder, the pin 20 is moved around until it engages with the upper edge of the arcuate lug 19, and'dnringthe remainder of this movement, the pin 20 swings the lock bolt 17 down into the positi'on seen in full lines in Fig. 3. In this position of the pin cylinder, the key may be withdrawn, leaving the pin cylinder and bolt in locked position.
Inasmuch as the lock bolt protrudes through the T-shaped slot 27 of the keeper plate 24, it is impossible to move the doors lengthwise of each other or to spread them apart laterally of each other, and, consequently, the doors remain effectively locked together. Wishing to unlock the doors, the key is inserted into the lock cylinder and turned back through a complete circle, whereby the pin cylinder is turned back, the pin 20 engaging the lower edge of the lug 19, and turning the lock bolt back into upright or unlocked position. In this position of the lock bolt, the doors may be readily moved apart.
I claim as new, and desire to secure by Letters Patent:
1. In a lock for double doors and the like which are movable into a position with one partly behind the other, the combination with a cylinder lock concealed within one door, of a lock bolt mounted upon said cylinder lock and having a lost motion connection therewith, said lock bolt being movable in a plane at right angles to the door on an axis parallel with the plane thereof and arranged to be projected transversely through the side of the door, and a keeper plate on the other door arranged to be lockingly engaged by said lock bolt.
2. In a lock for double doors and the like which are movable into a position with one partly behind the other, the combination with a cylinder lock concealed within one door, of a lock bolt mounted upon said cylinder lock and movable in a plane at right angles to the door on an axis parallel wit-h the plane thereof, said lock bolt having a shank provided with lugs on its tree end, and a slotted keeper plate on the other door arranged for locking engagement with said lock bolt.
3. In a lock for double doors and the like. the combination with a face plate and a lock mechanism secured thereto and concealed within one door, said lock mechanism having a cylinder rotatii'ely mounted therein on an axis parallel with the plane of the door, a lock bolt mounted on said cylinder and having shoulders on its free end said lock bolt being movable in a direction transversely of the door, a lost motion connection between said cylinder and lock bolt and a keeper plate- JOSEPH TAUSSIG.
