Description
N. W. BONNEY, OF VICTORIA, TEXAS.
BOLT FOR DOORS.
Specicaton of Letters Patent No. 28,827, dated June 26, 1860.
To all whom it may concer/n:
Be it known that I, N. WV. BONNEY, of Victoria, in the county of Victoria and State of Texas, have invented a new and useful Improvement in Bolts for Doors, &c.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l, represents a front view and partial section of the door when open. Fig. 2, a vertical section of the door when locked, and Fig. 3, a horizontal cross section.
Similar letters of reference, in each of the several gures indicate corresponding parts. Y
The nature of my invention consists 1st. In the combination of a lever, stop, cam and spring with the two wings of a door in the manner and for the purpose hereafter to be described.
To enable others, skilled in the art, to make and use my invention, I will proceed to describe its construction and'operation.
The sill of the door is provided with a recess s, for the reception of a lever a., pivoted in its center at n. The bottom of this recess is closed with a plate g, made with two holes for the pin or stop j, and the cam shaped projection z', to work through. The stop y', and cam i, are arranged at the opposite ends of lever a, and project from the lever downward. They are both of such length that the one projects through and below the plate g, while the other one is pressed back above the plate g, and vice-- versa. The cam z', is arranged above that door wing m, which contains the bolt of the door lock h, and the stop j, is arranged above the other wing n, containing the recess into which the bolt locks. The top edge of the wing m, carries a shield plate 0, and the top edge of'wing n, a similar plate p, the latter being provided with a hole corresponding with the situation of stop j, and with a recess f, in the top of wing n.
Vhen it is desired to lock both wings of the door, the wing n, is closed first, which can be done as the stop y', is held above the plate g, so as to be out of the way, by the action of a spring Z), which is fastened inside of the recess s, at c, and serves to press down the other or cam end of the leverl a. After the wing fn., has-been closed, the wing m, is also closed. While the latter wing is being closed down, so as to cause the bolt of the door lock z, to drop into the corresponding recess in wing n, the cam i, comes in contact with the plate o, at the top edge of doorwing m, and this end of the lever is pressed up until the cam i, is above the plate g. This of course causes the other end of the lever and stop j, to move down until the stop enters through the hole in top plate 72, intorecess f, in the top edge of wing a. It will be seen that by this means, both wings of the door are simultaneously locked and the doorl cannot be opened except by withdrawing the bolt of loclr L, and rst opening wing m, thereby allowing the spring again to depress the cam end of lever a and raising the stop j, out of recess f, after which the other wing n, can also be opened. The advantage of this arrangement is that by closing the wings n, and m, (in the manner above described) both wings ofthe door are automatically locked, an advantage which could not be obtained by using only one stop or cam in combination with a simple spring without the double acting lever a. Another and an important advantage is that when one wing of the door is swung open, the other is automatically unbolted and can be instantly opened withoutapplying the hand to the bolt.
In all window and door fasteners withA which I am familiar, the bolthas to be operated by the hand or thumb and therefore if the bolt is situated on top of the door, considerable diiiiculty of reaching it is experienced.
My bolt affords great safety, for if one wing is locked, the other will necessarily be bolted.
I do not claim a fastening which has to be operated by hand, as seen in Hochstrassers patent of 1853, but
IV hat I do claim as my invention, and desire to secure by Letters Patent, is-
The combination of alever stop y', cam i, and spring b, with the two wings m, n, of a door, when the same is so applied that the closing of the two wings brings the bolt into eifective action and the opening of the wing which has the lock applied to it allows the bolt to automatically cease its action, as herein set forth.
