5 Claims.

This invention relates to improvements in locks and pertains particularly to the class of locks designed for use in connection with hinged or swinging closures.

The primary object of the present invention is to provide a lock having a bolt and keeper, in which the bolt, when actuated for releasing or securing the closure, executes two movements whereby a certain function is performed in addition to that of securing or releasing the closure for movement.

Another object of the invention is to provide an improved lock for a swinging closure whereby upon the actuation of the lock for the release of the closure, the closure will be forced away from the jam against which it normally positions so that the closure will be partially opened at the The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:-

Figure 1 is a view in vertical section through a portion of a closure, such as a door, taken on a plane paralleling the side of the closure and passing through a portion of the lock embodying the present invention and the keeper therefor, the lock being in operatitve or looking position.

Figure 2 is a view of the essential portions of the lock, similar to Figure 1, and showing the lock bolt in unlocked position relative to the keeper.

Figure 3 is a sectional view taken substantially upon the line 33 of Figure 1.

Figure 4 is a sectiontal view taken substantially upon the line 4-4 of Figure 2.

Figure 5 is a view in elevation of the lock in position in the closure member showing the bolt in the position assumed when the closure is secured. I

Figure 6 is a sectional view taken on the line 6--6 of Figure 3. Referring to the drawings wherein like numerals of reference designate corresponding parts throughout the several views, the numerals I and 5 In the edge of the door or closure which faces the jam 2, is formed a mortise 3 in which the body of the lock embodying the present invention is located, and in the face of the jam 2 which opposes the free vertical edge of the closure, is

formed a recess 4 in which is secured the keeper plate 5. This keeper plate is shown in elevation in Figure 6 and as shown, has a recess 6 cut into one edge which leads downwardly into an oblique- 1y directed slot 1. As illustrated, the inner vertical wall of the recess 6 is vertical or parallel with the longitudinal edges of the plate, as indicated at 8, while the inner wall of the slot 1 extends obliquely to the edges of the plate as indicated at 9. The longitudinal edge of the plate 5 through which the slot 6 opens, opens into the channel Hi 5 which extends longitudinally of the jam 2 in one side face so that the bolt of the lock which is about to be described, may move freely into and out of the keeper slot.

The lock proper comprises two spaced bodies which are indicated generally by the numerals l l and t2, the body ll being disposed above and in spaced relation with the body [2. These bodies H and 12 have extending therebetween' and connecting them, the side plates it which are of less width than the bodies which they connect and are countersunk in their side faces. The bodies H, I2 and I3 constitute the housing of the lock and will be hereinafter referred to generally as the housing. Secured across the end faces of the 0 bodies H and I2 is a face plate I4, the ends of which extend beyond the bodies or housing and are countersunk in the face .of the closure l in which the lock housing is mounted, as illustrated in Figure 1.

This face plate I4 is shown in front elevation in Figure 5, and has an opening therein which is indicated generally by the numeral I5 and which, as shown, is divided medially to form an upper portion which is of substantially twice the width of the lower portion, thus forming the shoulder It. The upper larger portion of the opening l5 of the plate 14 coincides with the recess 6 of the keeper plate 5, when the closure element is in closed position.

The opposed faces of the bodies I I and I2 have formed therein adjacent their forward ends, the alined bores I1 and I8. Between these bodies II and I2 is located a reciprocable member I 9, which has the pins 28 and 2| at its ends which move respectively in the bores I7 and I8. The bore I1 is of greater diameter than the bore I8 to accommodate the coil spring 22 which presses at one n ain he i ner en of th o e d w h surrounds the pin 29 and presses .at its other end against the adjacent end of the body I9, thus normally forcing the body I9 toward and against the body I2 which forms a part of the lock housing.

Formed integral with the body I9 is the bolt 23 which projects therefrom through the opening I5 in the face plate I4. The opposite side of the body I9 from the bolt 23 has formed integral therewith the gear teeth 24. As illustrated, the two gear teeth which are nearest the pin 2I are directed obliquely of the body I9, while the remaining one is formed straight across the body. The purpose for this will be hereinafter more fully described.

Mounted between the plates I3 of the lock housing, for oscillation, is the bolt actuator 25, a por on of hi h i c rcu ar a own and-ex tending from the periphery of the circular portion are teeth 26, one of which is formed at an al el acr s h e phe y w ile the r maining ones are cut straight across the same. Between the straight teeth 26, the .straight one of the teeth 24 engages while the oblique one of the teeth 26 is adapted to engage between the oblique ones of the teeth 24 when the actuator is oscillated to shift the bolt carrying body l9,

Exten g from the periph ry of th bolt actuator 25 is a shoulder 21 with which a locking bolt 28 is adapted to engage. This locking bolt is slidably mounted in a recess 29 in the body I2, and is held in either one of two positions by means of the spring pressed pawl 30 which is located in a suitable recess in the body I2, as illustrated in Figure l where the bolt 28 is shown in engagement with the shoulder 21, in which position it operates to prevent the rotation of the lock bolt actuator 25. By inserting a suitable key into the opening 3|, for engagement with the pin 32 on which it may rotate, the bolt 28 can be engaged and retracted so as to release the actuator 25 so as to permit it to be swung to the position illustrated in Figure 2.

The swinging or oscillation of the actuator 25 is effected by means of the squared shaft 33 which passes through the lock housing and through the body of the closure I, as illustrated in Figures 3 and 4 and which carries upon its ends the handles or knobs 34.

In the operation of the present look, when the closure member I is in closed position, with the flange portion 35 in position in the channel II], the bolt 23 of the lock will be located in the lower and narrower part of the opening I5 in the plate III and in the lower part or slot 7 .of the keeper plate 5, and the relation of the body I9 and actuator 25 will be as illustrated in Figure 1. Assuming the locking bolt 28 to have been retracted from engagement with the shoulder 21, the tuming of the shaft 33 will effect the rotation of the actuator 25 and by reason of the intermeshing gears 24 and 26, will effect the shifting of the body I9 upwardly against the tension of the spring 22.

In its initial movement, the body I9 will move without oscillating due to the fact that the bolt 23 is moving in the straight lower portion of the opening I5. However, as the bolt is also moving in the obliquely directed slot 1, it will contact the rear wall of this slot and effect a pushing movement against the jam which will tend to force the closure I outwardly or away from the jam. The 5 outward movement of the closure member I is only very slight, as illustrated in Figure 4, and as soon as the bolt 23 reaches the upper part of he openin Is, the obliqu ones of h e r 24 and 26 will be meshed and because of their angul0 lar relation, and the fact that the body I9 is mounted so that it may oscillate on the pin 2|, whereas the actuator 25 can only move in one dimotion, the body I9 will be caused to oscillate and thus move the bolt 23 over onto the shoulder 15 I5 in the upper part of the opening I5, where it will remain While the door or closure member I is being swung outwardly or to open position. This second position of the parts I9 and 25 is illustrated in Figure 2. 2O

-When the closure I is moved back into the opening, the bolt 23, which hadpreviously left the keeper through the recess 6, will re-enter the recess 6 of the keeper and will strike the inclined upper portion of the rear wall of the slot 25 1. Sufdci'ently strong or forceful contact with the inner wall of the recess 6 will cause the body I9 to be oscillated so that the bolt 23 will be shifted off of the shoulder I6 so that the compressed spring 22 will be enabled to force the 30' body I9 and bolt 23 downwardly, As the bolt moves down into the lower portion of the opening 5, it will move against the inclined wall of the slot I and thus draw the closure tightly into closed position. If the lock is to be secured so 35 that it cannot be actuated, this may then be done by shifting the locking bolt 28 with a suitable key, into the position in which it is shown in Figure ,1.

From the foregoing, it 'will be readily apparent 40' that in the lock herein described, the latching bolt describes two movements, both when releasing the closure member and when securing it, the first movement being longitudinally of the closure and the second being in an ,arcuate path transversely of the closure, when the closure is being released, and the reverse order being followed when the closure is being secured.

It will also be apparent that While the closure may be automatically secured by being swung to, as in the present types of looks, it is automatically started in its opening movement when the latch and bolt is actuated to release it, which is a feature which present types of locks do not have. By this means, if the lock is used on a 5g refrigerator or other type of door where sealing gaskets are interposed between the contacting surfaces, the seal will be automatically broken so that the initial strain upon the operator of opening the door is eliminated.

What is claimed is:-

1. In a lock for a swinging closure, a housing, a pair of spaced members forming a part of the housing and having alined passages therein,

a body disposed between said spaced members, pins carried by the body for reciprocatory and oscillatory movement in the passages, resilient means normally urging said body longitudinally in one direction, a bolt carried by and projecting from said body, actuating'means for shifting said 10' body longitudinally against the tension of said resilient means and including intermeshing rack and gear teeth, certain of which are disposed obliquely to the path of travel of the body whereby the body is caused to oscillate and an ofiset shoulder arranged to have said bolt move thereonto through the oscillation of the body when the latter reaches the limit of its longitudinal movement against the resilient means.

2. In a hinged closure latching device including a keeper, having an entrance recess and a slot opening therefrom, a pawl: engageable in said. recess and slot, means carrying the pawl mounted to move in two directions, gear actuating means for causing the pawl to successively move in the said two directions for effecting its disengagement from the keeper, and means whereby the pawl will, in moving in one of the two directions, effect the prying open of the closure.

3.
