DOOR-LOCK.

SPECIFICATION fanning part'cf Iietters Patent No. 21,728, dated May 11, 1886,

Application filed April 30, 1835. Serial No. 163,944. (Modeh) Patented in (.anaa November 28,1884, No. 20,655.

.To ctZZ whom it may concern:

Be it known that l, ULRIC GABON, a citizen of Canada, residing at St. Thomas de Pierreville, in the county of Yamaska, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Door- Loeks, (partly patented in Canada under No. 20,655, bearing date November 28, 1884,) of which the following is a specification.

hilyinvention is embodied in the peculiarlyconstrueted lock herein shown and described; and it eonsists,partly,in the key and the con neetion of the lock knobs to their shanks,and partlyin the internal mechanism of the lock, all of which is fully hereinafter described, reference being had to the annexed drawings, in which- Figure]. is an elevation of the interior of the lock, showing the operation of the key and bolts. Fig. 2 is a section on line is as, Fig. 1. Fig. 3 is a section on line 3 y, same-figure.

. Fig. L is a longitudinal section of the shank of the latch knob or handle. Fig. 5 is a face view of the holding-barhereinafter described. Fig. 6 is a part outside view of a door having my improved lock, showing pieces covering the key-hole and the knob. Fig. 7 is a per spective view of the key.

The look here shown developes the principle of throwing locking-bolts out in different directions, so as to project into several of the sides of the door-frame, by means of gearwheel and racks, as herein shown and described.

A represents the front side, B the bottom side, and O the rear side, of the lock-case.

a a a are a series of locking-bolts,which may be projected outward from the lock into suitable recesses formed to receive them in the jamb of the door.

b is a lockingbolt arranged to slide upward into the door-lintel, and c is a similar bolt, to be thrown downward into the doorsill.

The bolts a are connected by the bar D, to which is attached the inwardly-proj ecting arm (I. On theedge of this arm, as also on theinner portions of the locking-bolts b and c, toothed racks are formed to mesh into a gearwheel, E,whieh is keyed or otherwise secured on the shank of the door knobs or handles, so

that all of the loekingbolts a, b, and 0, unless otherwise prevented, may be moved simultaneously inward or outward by turning the door-knobs.

F is a holding-bar movable endwise in suit able guides, andis for the purpose of holding ing the locking-bolts out when the door is locked.

G is a tumbler overlying the bar F, pivoted at e to the plate of the lock, and provided with an inivaidly-pi'ojecting lug, f, the use of which is to hold theholdingbar, either inward or outward, as it is thrown by thespring 9 into either of the notches h h in the bar. hen in its outward position the holding-bar is also held i'ronr moving by the bolt H, which slides in a vertical channel, and is held up into the recess h in the holding-bar F by the spring j and 7.: are two wards formed in the holding bar to take in the wings of the key, which I will now describe, and which forms an important part of my invention.

Thekey is provided with two wings, H and I, the wing ll being fixedyuhile the wing l is movable. The stem of the keyis made in two parts--the hollow stem J, on which the wing H is formed, and the inside stem, K, on which the wing I is formed, and which turns loosely inside the stem J. An opening is made in the hollow stem J, through which the wing I protrudes. Itis made wide enough to allow the wing to swing around SllllfiClBlltlY for the purpose for which itis intended. The stem K extends for a short distance out of the stem J, and has the arm Z secured on its end by thenut m. This arm sweeps over the circular graduated scale L,whieh is fixed transverselyin the key, as shown, for the purpose hereinafter stated.

The cover of the key-hole M on the outside of the door is made in the two pieces a and 0, which are pivoted tothe door in their outer and upper corners, as shown. They close and are locked together by the arrow-headed boltp, which is fixed in the half-cover 12, en tering between two spring-jaws in the halfcover, 0, where it is held until released by pressing the wedge-pointed bolt q between the same two jaws. A series of knobs, 1', similar in appearance to the end of the bolt q is shown on the outside of the half-covers n and 0, for the purpose ofdisguising the real means of opening the covers. In a small chamber between the casing of the lock and the door a small slide is held by a spring to cover the key-hole, so that an Ordinary key cannot be inserted.

In looking the door the operation of this look is as follows: First, the knob is turned so as to throw all the locking-bolts out. The key is then inserted in the key-hole. The wedge s, on the end of the key, entering at the side, moves the slide above mentioned aside. The key is then turned around so that the wing H, by pressing against the foot of the tumbler G, liftsthelug font of the notch h, and the wing H, pressing against the innerface of the ward 70, moves the holding-bar outward until it comes against the inner end of the arm (I, which, with all the loekingbolts, has previously been thrown forward by turning the gear-wheel by the knob or handle, as abovedescribed. The lug f then drops into the notch h, and at the same time the vertical bolt H is moved by the spring 2' up into the recess h", so that the holding'bar is thereby further held from movi-ngback.

.[n unlocking the door the key is first inserted in the key-hole. The wings are then opened by turning the arm Z around to the proper point, as indicated on the circular scale L. The key is then turned so that the wing I, by raising the tumber G, lifts the lug f out of the notch h in the holding-bar. In the meantime the wing H, by raising the outer end of the lever M, has drawn the vertical bolt H down out of the recess h. The bold ing-bar is then thrown back by the continued pressure of the wings of the key against the inner sides of the wardsj and it until the lugf falls into the notch h. The locking-bolts a, b, and a may then be all drawn back into the look by simply turning the door-knob.

Another important feature of-my invention is the connection of the door or lock knobs with their shanks, which is as follows: The gear-Wheel E, above mentioned, is fixed rigidly on a sleeve, 25, in which the knob-shank N is firmly secured. O is the socket of the knob or handle, and through which the shank N passes, and which is prevented from falling off said shank by the enlargement to. o is a slide-bolt working in the socket O and connected with the button 10 on the outside of the socket, so that it may be moved by it into or out of a notch formed in the end of the sleeve t. The object of this is that the doorknob may be made to turn the shank or re- Volve independently on it, as desired.

Having thus described my improved look, what I claim as my invention is 1. In a lock, in combination with the locking-bolts, a holding-bar, F, provided with notches and movable endwise in suitable guides, the pivoted tumbler provided with the inwardly-projecting lug adapted to engage said notches, and to hold the holdingbar, and the spring for throwing the said projecting lug of the tumbler into the notches of the bar F, substantially as and for the purpose described.

2. The holding-bar F, provided with a recess, h", in combination with the bolt H, sliding in a vertical channel, and the spring i. whereby the holding-bar, when in its outward position, is held from moving, substantially as described.

3. In a door-lock, thekey in two parts, consisting of the hollow stem J and the inside stem, K, and provided with two wings, H and I, H being fixed upon the said stem J and I movable with the inside stem, K, the arm 6, secured to the stem K, in combination witha graduated pivoted tumbler and holding-bar, whereby when the arm of the key is turned to the proper point the tumbler is raised out of the holding-bar, substantially as described.
