Description
- zen of the United States, residing at Wil-` iJNiTED ISAAC WHITE, 0F WiLiviiNGToN,' DELAWARE y LOCK.
To all whom timmy concern.'
Be it known that I, sAAo .WHITE a citimington, county of New Castle, Aan 3lState of Delaware, have invented a new and useful Improvement in Locks, of which the following is a full, clear, and exact description, yreference being had to the accompanying drawings, which form a part of this specification.
This invention relates to an impro-vement in locks, and more particularly to locks for doors.
The object of my invention is to provide a lock having a spring latch for latching the door and which is arrangedto be actuated by pressure applied to the door, whereby I am enabled to dispense with the usual knobs `together with their latch-actuating mechanism.
A lfurther object of my invention is to provide a lock having a combined latching and locking bolt, which is arranged to latch the door when in one position and to lock the door when in lanother position.
The precise nature of my invention will be best understood by reference to the accompanying drawings which will now be described, it being premised, however, that various changes may be made inthe details of construction, without departing from the spirit and scope of my invention as defined in the appended claims.
Figure 1 is a face view of one form oflock made in accordance with my invention, with the cover plate removed and in which the door and the door jamb are shown in section.
Fig. 2 is a sectional view on the line 22 of Fig. i;
Fig. 3 is a similar view on the-lineI3-3 the lock in the ofiiig. 4.. 1
In these drawings the referencel character 1 0l designates thedoor and 11 thejamb of theV door, with*l the usual slotted plate n A12 connected thereto.
Seated within `an opening in the door 10 is one form of my improved lock having a casing 13 provided with a cover 14 which` speeicpation of Letters Patent. 'Y Pate-umd May 17,1921, Application inea rune 3o, i920. seriai No. 392,974.. f
is secured to' the casing 13 by. the `screws 15. 16 is the usual front plate of a mortise lock such as shown, and 17 are screws for securing the lock to the door. Slidably mounted within the lock case 'is afcombinedlatch and lock bolt, having a f yoke 18 `and a bar '19 extendingrearwardly therefrom. 20 is a roller pivotally mounted Pivotally mounted on a pin 22 onv the casingis a lever 23, having a downwardly and forwardly extendingV portion 24, the forward end of which bears against the yoke 18, when the lock is in latching position. The'upper portion 0f the lever 23V extends over the bar 19, while the downwardly and forwardly extending portions are somewhat narrower and lie between the bar and the side of the casing, there being a detent v25 formed at the end' of the wider portions. This detent 25V is seated in recess 26 in the upperV face of bar 19.I when the bolt is `in latching position, and in a similar recess 27, when the bolt is in the locked position.
28 is a spring within the case which bears against the lever23 to hold the detent 25 in the recesses 26 and 27, as shown in Figs. 1 and 4, respectively.
. The door and casing 13 are provided With registering key holes for the reception of a key 29 to actuate the bolt t0 lock the door, or to place the bolt in its latching position.
.When the door is latched as shown in Figs. 1 and 2, the roller. 20 merely enters the opening in plate 12 and is restrained against further outward movement by the detent 25 and is at the same time yield* ingly held against furtherinward movement by the end of the forwardly extending mem- Vber 24 'of lever 23, which engages the backofthe yoke. 4The door canV be opened .byk
horizontal portion of the lever 23 against the action of the spring 28. This action of the lever will withdraw the detent 25 from recess 26 and place the yoke 18 under,
the action of the spring, and as soon as the roller has cleared the plate 12, the spring 28 will force the yoke forwardly until the detent 25 enters the recess 26 which will prevent further movement thereof. The latching force of the bolt can be varied by changing the spring 28 to increase or clecrease Vthe pressure of the lever 28 on the yoke 18. Y
When it is desired to lock the door, the bolt is advanced into the opening in the jamb 11 by means of the key 29, which first engages the member 24 of lever 23, and raises it, together with the detent 25, to first release the bolt, and then advances the bolt to the position shown in Fig. 4 by engaging the wall of a recess 30 in the bar 19. The bolt will be retained in this position by the engagement ofthe detent with the walls of the recess 27, and in order to slip the bolt, it will be necessary to first raise the lever 23, which can be done with the key when turning it in the reverse direction and the further movement of the key will return the bolt by engagement with the side of the recess 30.
InV the drawings the lower surface of the forwardly extending portion 241 of the lever 23 is flat, but it will readily be understood that this surface may be of any desired shape, while the engaging face of the key would be correspondingly shaped.
The advantages of my invention result from the provision of a lock having a combined latching and locking bolt, which is arranged to latch the door when in one position and lock the door when in another position. Also from the provision of a spring actuated lever, which is arranged to inaintain the bolt under spring pressure when in its latching position, and to lock the bolt, when the bolt is in its locking position. Further, from the provision of a locking bolt and spring lever arranged to be actuated'by a key to first release the bolt and then shiftr it from one position to the other. Having now fully described my invention, what I claim and desire to protect by Letters Patent is:
1. lock having a casing, a slidingbolt. a spring actuated lever pivoted to the casi ing, a detent on said lever, a plurality of lrecesses in therbolt arranged to be engaged Y by the detent to lock the bolt in different positions, and means on the lever for maintaining the bolt under spring pressure in one direction when in one position.
2. A lock having a casing, a single bolt arranged to latch a door when inone position and to lock the door when in another position, a spring pressed lever pivoted to the casing and arranged to maintain the bolt in latching position and hold it against being shifted into locking position, and coacting means on the bolt and lever for locking the bolt when in its locking position.
3. A look having a casing, a single bolt arranged to latch .a door when in one position and to lock the door when inanother position, a spring pressed lever pivoted'to the casing and arranged to maintain the bolt in latching position and hold it against being shifted to locking position,` and key surfaces on the lever and bolt arranged to first actuate the lever to release the bolt and to then shift the bolt when engaged with a ke A lock having a casing, a bolt arranged to be placed in either locking or latching position, key engaging means for shifting the bolt from one position to the other, and a spring-actuated lever pivoted to the casing for retaining the bolt in either position and for permitting the bolt to be moved to unlatched position and for retaining the bolt in its latohed position.
5. A lock having a casing, a bolt arranged to be placed in either locking or latching position, key engaging means for shifting the bolt from one position to the other, recesses in said bolt, a lever pivoted to the cas# ing and having a detent for engaging said recesses for retaining the bolt in its locking position and for restraining the bolt from moving from its latching position to its locking position, a spring for retaining the lever in its normal position, and a projection Von the 4lever for engagingthe bolt when in latching position for yieldingly holding it in such position.
6. Alock having a casing, a bolt arranged to be placed in either locking or latching position, key engaging means for shifting the bolt from one position to the other, a springeactuated lever pivoted to the casing, means on the lever and bolt for retaining iio the bolt in its locking and latching positions,
and means on said lever arranged to be engaged by the key to first release the bolt be-v fore the bolt is shifted by said key.
` 7. A lock having Va casing, a bolt arranged to be placed in eitherlocking or latching position, key engaging means for shifting the bolt from one position to the other, and a spring lever pivoted to the casing for retaining the bolt in locking position and for yieldingly holding said bolt in latching position. Y
. In testimony of which invention, I have hereunto set my hand, Vat Wilmington, Del., on this 28th day of June, 1920.
