KEY ACTUATED LOCKING BOLT Filed Sept. 18, 1935 Z6 Z-Ml? gmc/whoa',

Patented Nov. 2, 1937 UNITED sTATEs PAT-ENT OFFICE KEY ACTUATED' LOCKING 'BOLT Application September 18, 1935, Serial.No.,41,1-15

10 Claims. (Cl. 70-90) This invention relates to sliding `boltsfof the push-pull type commonly used for securing swinging and sliding doors, closets, drawers, windows and o-therclosures, and aims to provide for locking the same in both retracted and projected positions.

The invention further aims to improve bolt locksof the multiple tumbler type .for all purposes for which a key actuated lock is desirable,

and particularly to safeguard such .locks from being jimmied or forced by any means readily available to unauthorized persons.

The invention enables a strong Yand secure bolt lock to be produced at low cost, applicable to many purposes for which heretofore no adequate key actuated lock has been available.

Other objects and advantages yof the invention appear in connection with the following description of two preferred forms kor embodiments of 20, the invention, illustrated in the accompanying drawing, wherein Fig. l is a part sectional and part side view of a locking boltillustrated as secured to the side of a door, window or other closure which swings a or slides in a frame, the bolt being shown in locking position;

Fig. l2 is a longitudinal cross-section thereof on the line 2-2 in Fig. l, looking in the direction of the arrows;

Fig. 3 is a cross section thereof on the line v3--3 in Fig. 1, showing the butt end of the bolt and key slot therein in elevation;

Fig. 4 is a transverse cross-section on the line 4 4 in Fig, l, looking in the direction of the arrows;

Fig. 5 is a disassembled perspective View of the plunger, and shell; and

Fig. 6 is a vertical cross-section through a double hung window sash showing a mortisetype bolt lock embodying the invention.

In `the form of the invention illustrated in Figs. 1 to v5 inclusive, the body or housing II is :provided with a stud I2 to seat in a corresponding hole drilled in the face of the door style, meeting rail, or other movable part that is .to carry it,

and base flanges I3 whereby it may be secured,

against. the face of the door or thelike by 'screws if desired. The body is drilled lengthwise to receive the lock shell I4, which may be `secured thereinby means of ia set screw I5. Such a lhousing bodyl may be'readily secured to rany outwardlyr opening closure member that rit is desired to lock by means of a `sliding b olt mounted on its exterior,'and when the closure is locked into its frame,

thehousixlg -body .cannot bememoved without .un-

locking it. No claim is made herein to the combination of housing body and stud with the sliding bolt, this feature of the invention being the subject-matter of my application Ser. No. 41,116, filed vSeptember 1-8, 1935.

The lock shell is hollow to receive the sliding bolt I6 and is slotted lengthwise and circumferentially as shown in Fig. 5 to receive the guiding and locking pin I1 which is driven into the bolt near its butt end. At the forward end of the housingis an inturned flange I8 which closes the end of the bore except for the hole through which the forward end of the .bolt protrudes in projected or locking position. In the form shown in Fig. 6 this flange is on the end of the shell. The shell is provided with spaced openings I9, 20 for receiving the ends of the locking pins or discs 2I, for locking the bolt in locking and .retracted positions respectively.

These locking members 2| are mounted in cross slots 22 in the bolt ,body and are normally held in their outward positions with their ends projecting into one or the other of the openings I9, 2D, by small coil springs 23 disposed in staggered holes drilled in the bolt body at rthe ends of the cross slots 22. These locking members or tumblers have openings through which the key 24 passes when inserted in the axial slot 25 in the butt end of the bolt, the dimensions of these openings cooperating with the nibs on the key for alining all theplockingmernbers with their ends flush with the bolt body when the key is inserted to permit manipulation of the bolt. Thus when the key is inserted in the bolt to its proper seat, the bolt can be moved endwise and rotated thereby, its movements being guided by the pin I1 working in the slot in the shell.

A coil spring 26 is arranged in the space between the flange I8 and a shoulder on the bolt adjacent its body to retract it when unlocked by the key and rotated so .that the guide pin I'I is in alinement with the longitudinal portion 21 of f the slot in the shell. A notch 28 is provided at the end of the transverse portion of the slot in the shell into which the spring 26 forces the pin I1 in the protruded or locking position of the bolt. Unless the mating key is in its proper place in the slot provided for it in the butt end of the bolt, the ends of the pins or discs 2I engage in one or the other of the opposite openings of the pairs I9, 20 in the shell to prevent the bolt from turning, thereby' safeguarding the bolt against movement should an. attempt be made to turn it by a false key, screw driver or like implement inserted in the key slotcure it in place in the sash. The operation of the lock is the same as that shown in Figs. 1 to 5.V

No claim is made herein to thev split bushing and mounting for the bolt lock, this feature of the invention being the subject-matter of my application Serial No. 127,225, filed vFebruary 23, 1937.

The housing, shell and body portion of the bolt may be made accurately and cheaply by die-casting methods, and the key and pin discs are readily stamped from sheet metal, therebyenabling the lock to be produced at minimum cost.

Modification of the shape and arrangement of the parts and changes in the dimensions to suit different types of lock and places of use may be made without departing from my invention which is not restricted to the illustrative embodiments herein described.
