  • these locking members is moving into clos-' My invention relates to locksand, in one form, includes a bolt and a spring for maintaining the bolt in a withdrawn or unlocking position when the lock is not to function.
  • This bolt is desirably rotatably mounted and is preferabl adapted formovement by engagement with the locking member complemental thereto when the carrier for one of ing engagement, with the other carrier or is having an opening movement.
  • the bolt is carried on the door and the locking member complemental to the bolt is carried by the door jamb or is a formation provided on the door jamb.
  • a detent is preferably employed for holding the bolt in looking position so that the door cannot be swung away from the jamb until this detent is released.
  • a manually controlled detent actuating device is employed for releasing the detent from engagement with the bolt when the door is to be opened and when the detent is released the door may be swung open, as the bolt will then be free to turn.
  • the aforesaid spring in one form of my invention, serves to hold the bolt in unlocking position so that the bolt cannot then project beyond the meeting face of the door in a manner to prevent 'the door from being closed;
  • This spring is also desirably effective in completing the withdrawing movement of the bolt into an unlocking position, the locking memberor portion on'the door jamb turning the 'bolt'partially to its unlocking position to a point where the spring maybe effective to complete ,the movement of the bolt to the Specification of lieissued Letters Patent. Reissued Oct. 28, 1919.
  • Fig. 2 is a view similar to Fig. 1 excepting that the bolt is shown very near its completely withdrawn position, the door being slightly open;
  • Fig. 3 is a view on line 3-3 of Fig. 1;
  • Fig. 4 is a View on line H of Fig. 1;
  • Fig. 5 is an elevation of parts as they appear in Fig. 1;
  • Fig. 6 is a perspective view of the bolt
  • Fig. 7 is a sectional plan view of the preferred form of the invention, this fi ure showin a, door (broken away) and a oor jamb, t e bolt of the lock being in looking position;
  • Fig. 8 is a view similar to Fig. 7 excepting that the bolt is shown very near its completely withdrawn position, the door being slightly open;
  • Fig. 9 is a view on line 99 of Fi 7
  • Fig. 10 is a view on line 1010 of Fig. 7.
  • Like parts are indicated by similar characters of reference throughout the. different figures. 'v
  • a bolt 1 that is preferably pivotally mounted upon the door or other closure 2, constituting a carrier for the bolt, there bein a pivot shaft 3 upon the door for the bolt.
  • he bolt carries a crank arm 4 that is engaged by one end of a coiled spring 5, the other end of the coiled spring being flexibly connected 100 with the detent 6.
  • the detent is also pivotally mounted upon the door, as indicated at g, 1and carries a lug 8 adaptedto engage the Referring first more particularly to the 106 sion of the coiled spring 5 is such that the'110 ends thereof tend to approach each other .whereby said spring serves to thrust the bolt outwardly into a locking position.
  • the bolt 1 is held in either of its alternative positions' by means of the spring 5 whose end that is connectedwith thevcrank arm 4 lies upon one side of the pivot shaft 3 when the 7 'bolt is in the locking position and u on the the form of a lug bolt is projected other side of this shaft when the b0 t is in an unlocking position (see Figs. 7 and 8.).
  • the bolt 1 is turned in acounter-clokwise direction until it engages the stop 13 to bring the end of the spring 5 that is connected with the bolt upon the other side of the shaft 3, as indicated in Fig. 8.
  • the bolt portion 14 (preferably in or projection) upon the eyond the door so as to be engaged'by thedoor jamb 11 when the door is being closed whereby the bolt will be turned in a clockwise direction sutficiently to enable the spring 5to thrust the tion.
  • the detent 6 is therefore to be with.- to
  • the lug 8 upon the detent 6 holds the bolt in looking position as indicated in Fig. 7 but has no restraininginfiuence upon the bolt when the bolt is not in a locking posidrawn whenever the door .2 is tobe opened, any suitable mechanism being employed for this purpose.
  • end of the spring 5 that is opposite to the end connected with the locking bolt may be connected with an arm 19 in rigid relation to the detent 6 whereby the detent lug 8 is forced into holding engagement With the-locking bolt 1 when the door is closed.
  • a lock including a rotatably mounted l bolt, a for turning the bolt in looking and unlocking movements, a detent for engaging the bolt to hold it in looking position, and a manually engageable detent actuating element for releasing the detent from engagement with the bolt, said bolt' having a portion for engagement to effect the turning of the bolt to locking position and positioned for such engagement when the bolt is planned in an unlocking position, the spring being also connected with the detent to force it into holding engagement locking position.
  • a lock having an active latch member and a passive latch mem'ber cooperating therewith, a secondary latch for anchoring said active latch member in latching position, manual means to release said latch, and
