SPECIFICATICN forming part of Letters Patent N 0. 693,602, dated February 18, 1902.
Application filed August 10, 1901. Serial No, 711626. (No model.)
T0 all) 2071,0122, it; may concern.-
Be it known that I, FREDRICH A. HIoKsoN, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented anew and useful Irn provement in Locks; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings.
This invention relates to that class of locks which are used for fastening blinds and donble doors and are adapted to be operated without keys. Its object is to render such locks entirely secure when locked and unpickable by means of a wire or hook, and yet be readily operated by hand.
To this end my invention consists in the construction and combination of parts forming a lock hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which Figure I is a face view of a lock according to my invention and a portion of two blinds locked thereby. Fig. II represents a vertical section at line 00 with the bolt fastened by the latches. Fig. III represents a vertical section at the same line so with the latches raised, leaving the bolt free to be turned for unlocking or locking the blinds. Fig. 1V is a face view of a blank punched to form the box portion of the lock-body. Fig. V is a face view of the blank as punched out to form the back of the body. Fig. VI is a top view of the lock with the latches raised, as in Fig. III.
7 represents the bolt, which is pivoted at 8 to revolve freely on a back piece 9, that is secured upon one of the blinds 10 by means of screws 11.
12 is a back piece secured to the other blind 13 by means of screws 14, and 15'is the box portion of the body of the look. This box is first punched out of sheet-steel or other suitable material into the form shown in Fig. IV, and then its sides 19 are bent at the dotted lines 16, so that the studs 17 will register with and enter the holes 18 in the back 12, where they are to be secured by riveting them at the back after the three latches 20, 21, and 22 have been inserted between the said sides. The sides 19 are notched at 23 to serve as a double keeper for the bolt 7 in looking the blinds. These sides, being some distance apart along the bolt and fitting closely to the bolt when it is locked, maintain the bolt so closely in line that the blinds when locked by it cannot be sprung open. The latches 21 and 22 are provided, respectively, with trunnions 25 and 26 as pivots to swing upon in the sides 19, and the latch 20 is provided with ears 30, through which and the sides 19 a pivot-rod 2i passes.
Each of the latches has an angular bend, as shown in the section views Figs. II and III. In Fig. II the latch 20 is hooked over the bolt to lock it. The latch 22 is bent to rest like a foot upon the latch 20 to hold the latter from being raised. The toe 27 of the foot, being too long to swing down between its pivot 26 and the latch 20, holds the foot as a brace against that latch, and the arm 28 of latch 21, projecting back from the pivot 25, serves as a second brace against the said latch 20 when the body of latch 21 hangs normally. The first step to unlock the blinds is to tip the toe 27 forward; second, to raise the latch 21, when the latch 20 will be free to be unhooked from the bolt, the latter being done by pressing back on the lower end of latch 20. This leaves the bolt 7 free, as shown in Fig. III, to be swung out from under the hasps, thus unlocking the blinds. The latch 20 is provided with a spring 29, whose action is to hold that latch,with its hook, normally closed, as in Fig. II, so that the latch 20 cannot be unhooked without a special effort, even after its double locking is undone, and if the spring 29 should fail to operate the latch 20 will be forced into service by bearing down 011 latch 21, and latch 22 may be returned to service in the locked position of Fig. II by lifting latch 21 a little above the free position shown in Fig. III. The latch 21 is wholly between the sides 19, so that there is no exposed space beneath the latch for a burglar to insert a wire, and the whole combination of this look is designed with a view to resist all efforts to unlock it that can be made by one hand of a burglar, even though he should cut a hole in the blinds and reach his hand in.
It is evident that this look could be used on a single door or blind, but it is particularly adapted for the joint of double doors or blinds. Having thus fully described my invention,
what I believe to be new, and desire to secure by Letters Patent, is the following: 7
1. The combination in locks,of a bolt adapted to swing on one of the members which are to be locked together; a box-shaped keeper open at one end to receive the said bolt and adapted to be fastened to the other of the said members; a latch pivoted in the said box and having a hook to engage the said bolt; a second latch pivoted in the box and having a foot fitted to rest by gravity as a brace between its pivot and the first-named latch; the second latch being also fitted to swing out of the path of the said first latch; and a third latch also pivoted in the said box and having one short arm and one long arm, the short arm being adapted to extend as a brace from the pivot of this latch to the first-named latch when the long arm of this third latch hangs normally, and further adapted to swing the said short arm out of the path of the said firstnamed brace by the act of raising the long arm, substantially as described.
2. In locks,a bolt pivoted to swing; a keeper for this bolt; a hook-latch for the bolt and two as described whereby the raising of the long arm of one locking-latch will push the other locking-latch and with it the hooking-latch into service, and the normal falling of the said long arm will locate the short arm of the said one locking-latch as a second lock to the said hook-latch.
In testimony whereof I atfix my signature in presence of two witnesses.
