SPECIFICATION forming part of Letters Patent No. 445,108, dated January 20, 1891.
Application filed .Tune 18, 1889. Serial No. 314,747. (No model.)
To all whom, it may concern:
Be it known that I, EDWARD \VRIGHT,arcl1itect, a subject of the Queen of Great Britain and Ireland, residing at Southend, in the county of Essex, England, have invented Improvements in Latches, of which the following is a specification. v
This invention relates to a constructionand arrangement of locks adapted for fastening doors.
The invention consists in certain novel features of construction and in combinations of parts more fully described hereinafter, and particularly pointed out in the claims.
For the purpose of locking the bolt when shot any suitable arrangement may be used. The bolt can be formed with an opening or recess intowhich a correspondinglyiormed locking-bolt may be inserted through a suitably-arranged aperture in the lock-frame, or a sliding locking-bolt and a tumbler arranged to be operated by akey maybe used. In some cases both of these lockin g arrangements may be provided.
Locks can be constructed in various forms according to my invention, and will not only obviate the risk of injury to the person or cloth ing that obtains, owing to projection of bolts of locks of ordinary kinds, but, furthermore, will afford a safeguard against picking, as when a door having such a lock is closed the look will not be accessible, for example, from within a room into which such door opens.
In the accompanying drawings, Figure 1 shows a construction of lock according to this invention, the cover of the lock being removed to show the internal parts and the catch being shown in section. The bolt is shown in the attitude it would occupy when depressed by the catch in the act of closing the door. Fig. 2 shows the door shut and the pivoted lock-bolt secured by a locking-bolt. Fig. 3 is a horizontal section of the same construction of lock, showing the door further secured by a flush-bolt. Under these conditions the door is secured both inside and out. Fig. 4 is a partial sectional view showing a modified construction of lock, the bolt being shot. Fig. 5 is a full sectional view of the same in the same position, dotted lines showing the bolt swung back. Fig. 6 is a view of a different form of this invention, the 1ocl-2- case and part of the lock being in section. Fig. 7 is an elevation of the same, the door being shown in section. Fig. 8 is a horizontal section taken through the lower portion of the lock-case of Figs. 6 and 7. Fig. 9 is a view similar to Fig. 6, illustrating a somewhat-modified construction. Fig. 10 is a horizontal section of the construction of Fig. 9, showing the lock-case and catch and adjacent parts of the door and easing. Fig. 11 is an elevation of part of the door and easing with an extension of the flush-bolt in section. Fig. 12 is a view similar to Fig. 2 of a lock with a right and left hand bolt which can be locked by flush locking-bolts from either side of the door. Fig. 13 is a sectional view showing a modified construction of the right and left hand bolt of Fig. 12.
l is a lock-bolt mounted on a pin or pivot 2 within a case 3, which is let in flush with the face of the door frame or casing 3. The catch 4c is let into the edge of the door and is situated at such a height that when the door is closed its cam-like edge 5 strikes against the edge 6 of the lock-bolt, depressing it so that it rides under and then rises up inside the catch, as shown in Fig. 2. This action is aided by the spring 16, or the lock-bolt may be so hung that its own weight serves the same purpose as the spring 16.
7 is a flush locking'bolt within the lockcase. It can be raised by the finger to take into the notch 8 in the lock-bolt and thus to lock that bolt. 9 is another flush-bolt in the face of the door. \Vhen shot, it engages with a hole in the door frame or casing 3,
No handle is shown on the door; but it is evident that any form of handle can be used, as the handle is or may be merely a fixture and need not be adjacent to the lock. On the inside a handle is not necessarily re quired.
Figs. at and5 are two views of a lock according to this invention, in which the pivoted lock-bolt can be itself locked both from the outside and from the inside of the door by means of locking-bolts, one arranged in the lock-case and one in the door or catch. That in the lock-case consists, in the example shown, of a horizontal locking'bolt 7, which can be shot under the lock-bolt, and the locking-bolt in the door or catch is a flush-bolt 9,
through the side of the lock-case, Fig. at.
5 1, against which the springs 16 act.
which can be shot under a notch in the nose of the lock-bolt by a finger-piece 9, or the locking-bolt 7 may be replaced by lockingpin 7, connected to a chain and passed In Fig. 4 one of two steel bushes is shown in the lock-case for the pivots of the lock-bolt.
The lock shown in Figs. (3, 7, and S is very similar to that shown in Figs. 1, 2, and 3, with IO the addition of means whereby the locking-' bolt 7 is adapted to be operated by means of a key. The bolt 7 is provided with a spring and a tumbler 7; but any known form of lock mechanism suitable for the purpose may be used.
In the arrangement of Figs. 9, 10, and 11 the lock is fixed on the door-casing instead of being let in fiush with the surface thereof, as in Figs. 6, 7, and 8, and the locking-bolt 7 is arranged vertically and is provided with a spring and tumbler 7 so that it may be operated by a key. The flush locking-bolt 9 is connected to the door-handle by an extension 9 that is arranged to slide in a slot 9, Fig.
11, formed in the door and adjacent part of the catch-plate, so that by moving the doorhandle horizontally the fiush locking-bolt may be caused to engage with or to release the lock-bolt 1 as desired. The flush lockingjo bolt may in some cases be independent of the door-handle and be provided with a fingerpiece 9, Fig. 10, by which it maybe directly operated by hand.
This lock can be applied to a door whichever side it be hung.
40 recessed at 12 for the reception of a flush locking-bolt carried by the catch.
In the modified construction of right and left handed lock shown in Fig. 13 the lockbolt 1 is shown provided with two extensions Flush locking-bolts 7 and 9 are provided for looking the lock-bolt 1 from either side of the door, as before.
In all the arrangements hereinfore specifi- [o cally described and illustrated it will be observed that the bolt is pivoted so that it has a circular motion; but it is obvious that the same results may be secured by the substitution of an equivalent. For instance, in the arrangement shown in Figs. 1, 2, and 3 the bolt 1 may be allowed to -slide vertically and be pressed upward by a spring, so that the action of the inclined surfaces in opening and shutting the door tends to depress the bolt in a vertical line. Such modifications are within the principle of my present invention; but I have not considered it necessary to describe and illustrate such modifications in detail.
What I claim 'is- V 1. The combination of a lock-case 3, adapted to be applied to a door-frame, a 'lock-bolt 1, pivoted in said case and formed with doubleinclined edges, a spring arranged to normally maintain the lock-bolt projected, a catch 4:, adapted to be mounted on a door and having a cam-shaped edge 5, and a locking-bolt 7. arranged to move in said lock-case and engage with said bolt 1, substantially as herein described, for the purpose set forth.
2. A look consisting in the combination of a case, a swinging lock-bolt pivoted therein and having its locking end held yieldingly projecting therefrom, the outer edge of said bolt being vertically beveled or inclined and provided with a locking inclined edge forming an angle with said outer edge, and the catch having the cam-shaped recess arranged to engage the outer edge of the bolt and depress the same, so that thelocking edge swings up into said recess, and means to lock said bolt, substantially as described.
3. A lock havinga bolt pivoted to swingin a vertical plane and formed with two inclined surfaces arranged at an angle to each other, a spring yieldinglyproj ecting said bolt, a catch arranged to act against one or the other of said inclined surfaces when the dooris opened or closed, a locking-bolt arranged in the lockcase to hold saidlock-bolt projected, and a supplementary locking-bolt carried by the door and capable of securing said lock-bJlt projected, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
