LOCK.

Specification of Letters Patent.

Patented Sept. 11, 1906.

The present invention provides a lock of. peculiar and novel structure capable of fastening a door when wholly or partly closed and maintaining itin the desired adjusted position.

The lock is designed most especially for car-doors, although it may be adapted for barn-doors, gates, and closures of every de scription, whether sliding, swinging, or tilting.

For a. full description of the invention and the merits thereof and also to acquire a knowledge ofthe details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the referred embodiment thereof is shown in t e accompanying drawings, in which Figure 1 is a view in elevation of a lock embodying the invention, showing the {same in connection with a portion of a door and its j amb or casement. similar to Fig. 1, parts being broken away Fig. 2 is a view and showing the relation of the lock-b ar when the door is partly open to admit of ventilation. Fig. 3 is an edge view of the lock, the lower part thereof being shown in section.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In design and finj sh the lock may be of any appearance, depending upon its size and the special purpose for which it is constructed. The casing for inclosing the operating parts may be of any formation, and, as shown, usually comprises a base-plate 1 and a capplate 2. The lock consists, essentially, of two parts-a lock-bar 3, preferably attached to the door or like closure 4, and a lock mechanism attached to the jamb or casement against which the door or like part 4 closes. The lock mechanism is relatively fixed, whereas the lock-bar 3 is adjustable with reference to the part to which it is attached, so as to admit oi the door 4 closing tight or remaining partly open to allow of ventilation.

The lock mechanism comprises a latchbolt 5, key-operated lock-bolt 6, tumbler 6 and the inclosing casing. The latch-bolt 5 has a limited movement and is projected across the path of the lock-bar 3 by means of a spring 7, the latter surrounding the o erating-rod 8, connected with the latch-b0 t and extended beyond the casing, so as to be pulled upon when it is required to disengage the latch-bolt from the lock-bar preliminary to opening the door 4. A notch 9 is formed in an edge or side of the latch-bolt to receive the key-operated lock-bolt 6 when the device is to be made secure against surreptitious opening by parties pulling upon the operating-rod 8. When the bolt 6 is projected into engagement with the latch-bolt 5, the latter is held fast and may not be moved until released by withdrawal of the bolt 6 through the intervention of a proper key, as will be readily comprehended.

If desired,a seal may be used in connec tion with the look by being passed through corresponding openings in parts of the lockbar and the casing of the lock mechanism.

The lock-bar 3 may be connected to the door or like part 4 in any substantial manner to admit of its adjustment, so that the door may be closed tightly or left partly open, as required. In any adjustment of the lock bar with reference to the part 4 it may be secured by the latch-bolt when shot into the casing of the lock mechanism, as indicated most clearly in Fig. 2. As shown, staples or keepers 10 and 11 are utilized for securing the lock-bar to the door 4. The keeper 10 is shorter than the keeper 11, and its members embrace opposite edges of the lock-bar, so as to prevent vertical movement of the inner end of said lock-bar when said bar is shot TOO , with or provided upon the lock-bar, limits the movement of the latter with reference to the casing of the lock mechanism and insures registry of the notch 14 near the outer end of the lock-bar with the latch-bolt when said lock-bar is shot into the casing of the lock mechanism. A series of notches 15 are formed in the lower edge of the lock-bar and are adapted to cooperate with a member or portion of the keeper 11, so as to hold the lock-bar in the adjusted position either when the door 4 is closed or left partly open. When the lock-bar is moved to the position shown in Fig. 1, it is held. in place by the outermost notch receiving a member of the keeper 11, the keeper l0 and lock mechanism acting jointly to prevent'vertical displacement of the lock-bar. In this adjustment of the lockzbar the door 4 is wholly closed. As shown in Fig. 2, the lock-bar is moved outward a distance corresponding to the required space to be provided between the door 4 and its j amb or casement, and its position is fixed by the'innermost notch receiving a part of the keeper 11 in the manner set forth in connection with the disclosure in Fig. 1.

The projection 13 and latch-bolt 5 serve to prevent longitudinal movement of the lockbar, and the latter being positively engaged with the keeper 11 holds the door 4 in the adjusted position, so that it may be neither opened nor closed except as herein provided. It is to be understood that any number of notches 15 may be provided, so that the ventilating-space may be regulated to meet varying conditions.

A projection 16 is provided at the lower edge of the lock-bar and may be formed in any manner, as by reducing the width of the lock-bar, as shown. The keepers 10 and 11 are so proportioned with respect to the lockbar 3 and so arranged with relation to the closure 4 that the lock-bar may be withdrawn sufiiciently for its end to clear the opening of the closure or door and leave the passage through the door undisturbed by the end of the lock-bar. When so withdrawn that the end of the lock-bar clears the opening of the door, the two flanges or projections 13 and 16 will abut against the keeper 10, and thereby prevent the bar from further withdrawal. The bar is held in this position until it is desired to shoot it back into the lock to fasten the door. This arrangement permits the use of this locking device on swinging doors or tilting doors, as the lockbar when so withdrawn is entirely clear of the opening and permits a swinging door or a tilting door to be entirely closed. This arrangement necessitates placing the keeper or staple 10 far enough from the edge of the door to permit the withdrawal of the lockbar just far enough so that when the flanges or projections 13 and 16 rest against the keeper 10 the end of the bar will just clear the opening.

Having thus described the invention, what is claimed as new is 1. In combination with a closure and its casement, and a lock mechanism applied to one of said parts, of a cooperating lock-bar provided with projecting portions to form stops and having a series of notches, and keepers of different lengths applied to the other of said parts, one of said keepers snugly embracing the opposite edges of the lock-bar to prevent movement of the inner end thereof in a vertical direction when the outer end of said bar is secured by said lock mechanism, and the other keeper adapted to cooperate with the notches of the lock-bar to fix its position, whereby the door is adapted to be fastened in the required adjusted position.

2. A lock comprising a lock-bar, a fixed lock mechanism designed to receive the outer end of said lock-bar to lock the same against relative movement, spaced-apart keepers for said lock-bar, the keeper adjacent the inner end of said lock-bar preventing the movement of such end in a vertical direction when the outer end of said bar is secured. by said.

lock mechanism, and the other keeper permitting a limited vertical movement of said lock-bar when the same is released from said locking mechanism said keeper designed to engage the lock-bar to prevent the longitudinal movement thereof, as and for the purpose set forth.

3. A look comprising a relatively fixed lock mechanism, a casing therefor, a sliding lock-bar arranged to enter said casing and to be held therein with its engaged end immovable both longitudinally and in a direction at right angles thereto, and two separate keepers in which said bar is designed to slide longitudinally, that keeper adjacent the inner end of the lock-barsnugly embracing the same, and the other keeper being longer than the former to permit the lock-bar to tilt, the said lock-bar being provided along one edge with notches adapted to cooperate with said longer keeper, whereby the lock-bar may be fastened in different extended positions.

4. In combination with aclosure and its casement, a lock mechanism applied to the casement, a sliding lock bar cooperating with the lock mechanism and having oppositely-disposed projections 13 and 16, and two keepers for the lock-bar attached to the closure, one of said keepers being relatively In testimony whereof I affix my signature large and allowing for the clear passage therein presence of two Witnesses. through of the look-bar, and the other of said keepers being adapted for engagement with EDWARD 5 the said projections to limit the withdrawal Witnesses: of the look-bar when moved to clear the open- T.
