KEYLESS L0 CK.
` Specification of Letters Patent.
Patented Mar. 25, 1919.
Application led September 20, 1918. Serial No. 254,990.
To all 'whom z't may concern Be it known that I, HARRY L. BooK, a citizen of the United States, residing at Honolulu, Territory of Hawaii, have invented certain new and useful Improvements in Keyless Locks, of which the following is a specification.
This invention relates to hardware, and more particularly to keyless locks.
The object of the invention is to provide a simply constructed and eiiicient lock which will reliably secure a closure and which cannot be released except by those knowing the combination.
Another object is to construct a lock of this character which may be cheaply manufactured and easily applied to any door.
lith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the prescise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings Figure l represents an inside View of a door equipped with this lock with parts broken out, the lock being shown in operative position in full lines.
Fig. 2 is a similar view Ytaken from the outside of the door, parts being broken out for convenience in illustration,
Fig. 3 is a detail section taken on the line 3-3 of Fig. 1,
Fig. 4 is a detail section taken on the line 4-4 of Fig. 1,
Fig. 5 is a detail perspective view of the locking bolt, and
Fig. 6 is a similar view of the bolt engaging lever. l
In the embodiment illustrated, the lock constituting this invention comprises a hook-shaped keeper1 mounted on the frame F of a door, with the beak or bill of the hook turned upwardly as shown in Fig. 1. A coperating locking bolt 2 is mounted for swinging movement in the door D having a rightangular arm 3 extending through the door and forming a ournal for the bolt, the outer end of said arm 3 being arranged on the outer face of the door and equipped with an actuating knob 4. This bolt 2 when swung into operative position has its free end projecting beyond the edge of the door and engaged with the keeper 1 as shown clearly in Fig. l.
An L-shaped locking lever 5 has its short arm G extended through the door D in a plane in advance of and above the bolt 2, its outer end, which is positioned on the outer face of the door, being provided with a knob 7, (see Fig. 2).. The door D has a slot 8 on its inner face arranged parallel with bolt 2 when the latter is in operative position, and which extends from the point where the lever 5 passes through the door to a point adjacent the front edge of the door. This groove S forms a seat for the long arm 6 of the lever 5 when the latter is in inoperative position, so that it will not interfere with the releasing movement of bolt 2.
A plate 9 is pivotally mounted on an L- shaped pivot member 10, the short arm 11 of which extends through the door in a plane above that occupied by the lever 5 and has an actuating knob 12 on its .outer end. The long arm 11 of the pivot 10 extends edgewise into one end of the plate 9 and by turning the knob 12, the plate 9 may be swung upward or downward at the will of the operator and is designed for locking lever 5 in operative position as shown in Fig. 1.
The plate 9 has a slot 13 extending longitudinally thereof near its free end and which is designed to receive a locking linger 14 carried by one end of a catch member 15. This catch member 15 extends through the door in a plane above that occuped by the pivot member 10, and its outer end is equipped with an actuating knob 16. The finger 14 of the member 15 is designed to extend through the slot 13 in plate 9 when said plate is in operative position, the linger being turned at an angle to the slot after its passage therethrough to hold the plate against upward or downward movement, as is shown clearly in Fig. 1.
In the operation of this lock, the parts being in the position shown in Figs. 1 and 2, w'hen it is desired to release bolt 2 for opening the door, the locking member 15 is given a partial rotation through the knob 16 to bring the finger 14 thereof in alinement with slot 13. A pull is then exerted on knob 16 which draws the finger 14 out of engagement with the plate 9, and this plate 9 may then be swung into upward posi-tion as shown in dotted lines in F ig. 1, tbe Swinging movement being accomplished by means ot' knob 12. Then the plate has been raised the bolt locking lever 5 may be swung through a par- 1 wardly until its long arm 6 rests on bolt Q as shown in Fig. 1. Plate 9 is then swung downwardly by turning knob 12 until its lower edge rests on lever arm 6. The yknob 16 is then grasped andthe member 15 moved inwardly until the linger lat carried thereby passes through slot 13 in plate 9. v The knob is then turned to bring the linger into the position shown in Fig. 1, at right angles to slot v13, and when in this position, the plate line is locked and cannot Abe turned on its pivot until the finger 1l is disengaged therefrom in the manner above described.
It will thus be seen that this lock, while very simple in construction, is thoroughly efiicient in operation andinay be readily applied to any door already in use.
The members of this lock on the inner face of :the door, may if desired, be incased in a suitable casing, not shown.
From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily ap parent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention vtogether with the device whichI now consider to be the best embodiment thereof, I desire to have .it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention. y
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:-
1. In a lock of the class described, a bolt having an arm for extension tlhrough the closure to be secured, and provided at its terminal with an actuating handle, a bolt locking rod for extension through the closure and adapted to be swung into the path of the locking bolt, a member mounted to swing over said rod to hold it in engage-ment with said bolt, and a locking device `for holding said member in engagement with the rod.`
2. In a lockof the class described, a bolt having a right iangular arm for extension tlhrough the closure to be secured, and provided at its terminal with an actuating handle, a bolt locking rod having a right angular arm for extension through the closure and adapted to be swung yinto the path of the locking bolt, a member mounted to swing n f over said rod to hold it in enga-gement with said bolt,and a locking device for holding said member in engagement with the rod.
3. In alock of the class describech'a bolt having a laterally extending arm witlh a knob at its free end, said arm beingadapted to operate as a journal for rthe bolt, an L- shaped bolt securing member provided with a knob at the free end of one arm, said arm being adapted to operate asa journal for said member, a 4plate pivotally mounted for engaging said member when in operative position, said plate having an aperture therein,
and a locking element adapted to extendy through said aperture to lock the plate in operative posi-tion.
4l. In a lock of the class described, a bolt having a laterally extending arm with a knob at its `free end, said arm being adapted to operateas a journal for they bolt, an L- shaped bolt securing memberprovided witlh a knob at the free end Vof one arm, said arm being adapted to operate as a journal for said member, a plate pivotally mounted for engaging said member when in operative position, said plate having an aperture therein, and a. locking element having a' laterally extending linger adapted to'project through said aperture and to be disposed a-t an angle to hold the plate in locked position.
In testimony whereotl I aixmy ksignature in presence of two witnesses.
