LOCK AND LATCH MECHANISM.
Specification of Letters Patent.
Patented June so, 1916.
Application filed October 14, 1915. Serial No. 55,889.
To all whom it may concern Latch Mechanisms; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.
- lock and latch mechanisms,
. My invention relates to improvements in its object the provision of a structure embodyinga deadlock in combination with a "latch, and so related that the latch serves it to control the position of the bolt of thelock.
Another and further purpose of my invention is to'reduce to a minimum the number of indiv'dual and separate elements re-v quired in a structure of this character, and to correlate them insuch a way as to make it possible to manufacture the device at a reasonably small cost, at the same time affording an arrangement which can be readily assembled or disassembled, and in which the parts are not likely to in any way in which the bolt can get out of order.
An additional purpose of the improve dead lock mechanism be positively retained in either its inner or outer positions, and so combined with a latch construction that ment is to afford a when the bolt is in its innermost position, it is automatically released and movedto its outer or looking position upon operation of the latch, and movement of the latch is al- 'sists in certain improvements and combina fully described,
ways necessary to permit movement of the 40 bolt. 7
To theseand otherends the invention conallas will be hereinafter more the novel features being pointed out in the claims at the end of the specification.
In the drawings: Figure 1 is a horizontal tions of parts sectional view llOWlIlg the application of a mechanism, showing the position of the preferred form of my invention to a door and casing; Fig. 2 is' a plan view of the parts with the latch and bolt in their outermost and innermost positionsrespectively;

inward movement;
Similar reference numerals in the several" latch member when the 'door isclosed,"
through a'beveled edge 4:, all as will appear more clearly from the detailed description to follow. l
The mechanism attached to the door is arranged within a housing 5, and includes acylindrical hollow bolt 6. The bolt includes a frame 7 which carriesa projection 8'for a purpose that will appear presently. The latch member; is designated at 9, being movable within the cylindrical bolt 6, and it lII-j cludesa plate 10, slidable within the sides of the frame 7 and supported in recesses 11 formed between the upper and lower lugs or flanges 23 of the-frame 7 as shown in Fig. 7, while the which rests upon the floor of the housing and maintains the parts in proper relation.
.Mounted'on a post 13 isa locking device preferably in 'the form of a pivoted detent 14 carrying a with a 'cam slot 16 in the latch -member, and 17' is a nose formed'on the detent and arranged to' engage on opposite sides of the projection 8 of the bolt, whereby to hold the bolt in either its inner or outer position against movement until the latch member is operated. Movement of the latch member inwardly causes the pin-15 to be moved lengthwise of the slot 16 'from the position shown in Fig;
bolt frame. carries a pin 12' pm 15 cooperating 2 to th t Q WD- s Fig. '3,- thus swinging the locking device away from engagement with the bolt and permitting free movement of the latter. If
the bolt happens to be in its inner position, upon closing the door, the latch will be moved inwardly, as already described, to release the bolt which is thereupon moved to its outer position by a spring 18 mounted on V the post 19 and engaging a wall of the housing and a pin 20 on the bolt frame; and when the bolt is in its outermost or locked position, provision is made for releasing the locking device or detent 14 by inward movement of the latch through an actuator that I will describe more fully a little later.
The locking device or detent 14 cooperates on opposite sides of the projection 8 for retaining the bolt. Thus when it is on one side of the projection 8, it holds the bolt in its outer position, as in Fig. 4, and when on the opposite side, it retains the bolt in its inner position, as in Fig.2. The latch member is held in its normal position through the action ofa spring 21 mounted on the afore mentioned post 19 with one end in engagement with the latch member and the opposite I end in engagement with the pin 15 of the detent, causing the latch member to be actuated under normal conditions to the position shown in Figs. 2 and 4. The actuator forinsertionof a proper key, the actuator will be turned to release the bolt 6. To this end,
the plate 22 includes cam surfaces 26, be
: tween which is a recess 27 that receives the pin 12 when the parts are positioned as shown in Fig. 4. Upon the initial movement of the actuator, one of the cam surfaces 26 engages a pin 12, moving the latch member inwardly far enough to release the locking device from engagement withthe bolt, while its further movement causes the bolt to be moved by engagement of the actuator with the flanges 23 on the bolt frame, as shown in Fig. 5. other side of the door without the aid of a key bya correspondingly formed actuator 28 which is connected to and operated-by a handle in the form of a knurled head 29 arranged on the outside of the housing. In case it is desired to retain the bolt permanently in its inner position, I provide a positive stop, consisting of a slide member 30, which carries a projection 31 adapted to be moved into the path of the bolt frame by a finger piece 32.
, its movement.
The bolt may be released from the The slide 30 carries a series of recesses 33 with which cooperates a spring pin 34 for frictionally holding it in either position of adjustment.
The operation of the structure may be described briefly as follows: With the parts in normal position, as shown in Fig. 2, the bolt being in its inner position, upon closing the door the latch 9 is forced inwardly, releasing the locking device from engagement with the bolt frame after which both the latch member and bolt are moved outwardly by their respective springs, and the bolt is locked in its outer position by the'detent 14. The lock may be opened either from the outside through the key controlled tumbler lock mechanism, or from the inside by turning the handle 29, initially causing inward movement of the latch member, and'thereby moving the lockingdevice or detent 14' out of engagement with the bolt frame, after which the bolt is free to be moved to its innermost position by continued turning of the actuator,'and the parts are then in the position shown in Fig. 2 ready for another operation.
I claim as my invention:
1. The combination with a hollow locking bolt, of a latch member movable within the bolt, and means controlled by the latch member acting to retain the bolt in its inner or outer position. i A
2. The combination with a hollow cylindrical locking. bolt, of a cylindrical latch member movable within the bolt, and a looking device arranged to engage the bolt and retain it in position, the latch member acting, during its initial inward movement, to release the locking device and permit movement of the bolt. i
3. The combination with a hollow locking bolt, of a latch member movable within the bolt, means controlled by the'latch member acting to retain the bolt in its'in'ner or outer position, and a stop adapted to be adjusted into the path of the' bolt to prevent 4. The combination with a hollow locking bolt, of a latch member movable within the bolt, a locking device arranged to engage said bolt and retain it in either its inner or outer position, the latch member having a pin and slot connection with the locking device whereby the latter is removed from engagement with the boltupon inward movement of the latch member.
5. The combination with a hollow cylindrical locking bolt, of a cylindrical latch member movable within the bolt, and means controlled by the latch member acting to hold the bolt against outward movement and operable to permit such movement.
6. The combination with a'hollow cylindrical locking bolt, of a cylindrical latch member movable within the bolt and a locking' device arranged to engage the bolt to retain it against outward movement and reing device arranged to engage the bolt to retain it against movement in either direction and releasable upon movement of the latch member.
