LOCK.

Application filed January 14, 1918. Serial No. 211,802.

To all whom it may concern:

Be it known that I, JoHN H. SHAW, a

citizen of the United States, residing in the city and county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Locks, of whlch the following is a full, clear, and exact description.

, This invention relates to looks, and more particularly to looks in which a pin tumbler lock mechanism is housed in a knob, and wherein the knob is employed to operate a bolt, the pin tumbler lock being constructed to lock the knob against rotation, so that the knob cannot be rotated to unlock the bolt operated thereby.

Heretofore, the pin tumbler lock mechanism mounted in a knob has usually been provided to operate a rollback, which, in turn, operated a sliding bolt. Inm improvement, the pin tumbler lock is rigidly secured to a fixed part of the door knob, and the key barrel of the lock is secured to the rotating knob, so that when the key is removed from the lock, the knob cannot be turned to unlock the door.

The primary objects of my invention are to provide an efficient knob lock constructed along the lines above indicated; to furnish a structure in which the knob shell is rotatably mounted upona fixed part of the door knob, and upon the cap piece mounted in the knob and rigidly secured to the fixed part; to provide means by which the pinv tumbler lock mounted inside the rotatable knob is rigidly secured to the door upon which the knob is mounted; to provide means for non-rotatably securing the rotatable knob to the key barrelyof the lock; to

rigidly connect the swinging bolt to the knob which operates the same; and to gen; erally improve the construction and operationof devices of the class to which my invention relates. i

To these and other ends, the invention consists of the novel features and combinations of parts to be hereinafter described and claimed. g

Fig. 11 is a rear end view of the pin tumbler lock; Fig. 12 is a front view of the knob shell with the cap piece and lock removed therefrom; and F 13 is a rear end view of the pin tumbler lock mounted upon the cap piece.

Referring to the drawings, I have shown my improved device, consisting of a door knob and a swinging bolt operated thereby,

a door frame 11, the'door knob being so positioned 'upon the door that the swinging bolt may be swung into locking engagement with the door frame, as shown in Fig. 3.

My improved door knob is provided with a hollow thimble 12, preferably having a pair of integral lugs 13 formed upon the rearface thereof, which lugs are adapted to be inserted in drill holes formed in the door 10, upon whiclithe knob is mounted,

to prevent the thimble from rotating relatively to'the door. The thimble 12 may be rigidly secured to the door 10 by means of 1 screws 14,'which pass through the door and into thethimble. Rotatably mounted within thethimble is a spindle 15, which spindle is rigidly secured to or formed integral-with the knob shell 16, and formed in the rear face of the shell 16 is an annular groove 17, in which the outer end of the thimble is seated, The inner end-of the spindle is referably provided with a poly 'onally shaped end 18, the object of which iivill be hereinafter described. In the outer face of the shell 16 is formed a relatively large round opening 19, in which opening is mounted a cap piece 20. The edge or face of the opening 19 is preferably beveled, as shown in Fi s. 4 and 5, and the outer periphery or e go of the cap piece 20 is provided with a corresponding bevel, the arrangement being such that the-cap piece will lie substantially flush with the outer face of the knob, but will not pass therethrough. The cap piece 20 is preferably provided with a pair of rigid, spaced legs 21, which legs extend across the 'interior of the shell 16 and have their ends projecting through arcuate slots 16' formed in the rear face of the shell 16, these legs being of sufli cient length to abut against the end of the thimble 12, so that the cap piece will be held properly seated in the opening 19, but will be prevented from binding or clamping against the outer face ofthe shell in which it is seated. Each of .the legs 21 has a threaded drill hole 22 formed in the rear I end thereof, the object of which will be presently described. Formed in the hollow thimble12, on opposite sides thereof, are drill holes 23, the outer ends of wh1ch are countersunk. Mounted in the drill holes 23am screws 24, the heads of these screws being entirely inclosed in the countersunk portion of the screw holes. These screws extend entirely through the thimble 12 and have threaded engagement with the screw holes 22 formed in the legs 21. From the above description, it will be apparent that when the elements so far describedhave been assembled, by inserting the splndle 15 of the shell 16 in the hollow thimble and by inserting the cap piece 20 in the opening 21, that these parts may be secured in their proper position by the screws 24.

It will also be apparent that when the parts are thus assembled, the. knob spindle 15 will be rotatably mounted within the thimble 12, and that the outer wall of the knob 16 is rotatably mounted upon the cap piece 20. L

The shell-like knob 16 is rigidly connected with a swinging bolt 25', which bolt preferably consists of a disk-like portion having an extension 26 formed thereupon.

Centrally formed in the disk-like. portion of'the bolt 25 is a polygonally shaped opening, adapted to receive the slmilarly formed end 18, above referred to, the arrangement bei such that the swinging bolt will be rigi 1y mounted upon the end of the spindle 15, so that the innerface of the bolt 25 contacts with the shoulders formed in produc- I ing the 'pol'ygonally shaped end 18, the bolt being securely fastened upon the spindle 15. by means of a srrew-27 having threaded engagement with a central opening formed in the spindle 15, the screw 27 being provided with a washer'28, which contacts with the outer face of the swinging bolt. The

swinging bolt 25 is preferably provided also with a notch 29, which coiiperates with a pin 30 rigidly mounted in the door 10,

the notch and cooperating pin providing a convenient means for limiting the are The structure so far described forms a' convenient means for opening and closing the door 10 and for operating the bolt 25 mounted on the inner face thereof. Desirable means for locking the knob so that thedoor 10 cannot be opened by anyone except-the person possessing the proper key, consists of the following mechanism. The cap piece 20, above referred to, has a round opening 31 formed in the outer face thereof, and a clearance space is formed between the legs 21 above referred to. In this clearance space is mounted a pin tumbler lock 32, the lock 32 being so positioned within the cap piece thatthe outer end of the key band 33 extends into the opening 31, and

the pin tumbler extension 34 is seated in a notch 35 formed, in the cap piece by providing lntegral lugs 36, 36 on opposite sides of the notch 35, the arrangement being such that the lock 32 is snugly mounted between the legs'21 and has one end of the pin tumbler extension 34 mounted in the notch 35 to prevent relative rotation between these two elements. The cylinder lock is provided with the usual'pin tumblers 37 operated by the key 38. In the inner end ofthe key barrel 33 is formed a slot 39, in which slot is seated the flattened end of a key rod 40, which end is held in the slot 39 by a washer 41 secured upon the inner end of the key barrel by means of screws 42. The spindle 15 has an opening43 formed therein adjacent the rear wall of the knob shell 16 (see particularly Fig. 12). This opening 43 is. adapted to non-rotatably re ceive the key rod 40, the arrangement being such that when the key barrel 33 is locked against rotation, the knob 16 will also be prevented fromrotating. By referring to Fig. 12, it will be seen that a small notch 44 is formed in the face of the opening 19. The object of this notch is to form a clearance space, in order that the pin tumbler lock 32 may be. inserted in the hollow knob 16.

Having described the different elements of-which my improved device is composed,

ject through the arcuate slots 16' formed in I the rear wall of the knob 16. The stem formed upon the knob 16 is then inserted in the hollow thimble 12, and the parts are retained in this position by the long screws 24;, which pass through the thimble 12 into the threaded drill holes 22 formed in the legs 21. The knob 16 is held against longitudinal movement in one directon by the end of the thimble 12, which extends' into the annular groove 17 and is held against longitudinal movement in the opposite direction by the beveled edge or periphery of the cap piece 20, which forms a bearing for the front Wall of the knob 16. The thimble is rigidly secured to the door 10 by the lugs 13 and screws lei, above described, and the cap piece is rigidly secured to the thimble by means of the screws 24. It willbe apparent that when the several parts of the knob are assembled, the pin tumbler lock 32,

which is non-rotatably seated in the cap, piece 20, will also be non-rotatably secured to the door 10, and that, since the key barrel 33 is positively connected to the rotating knob 16 by means of the key rod d0, the knob 16 cannot be rotated when the key barrel 33 is locked against rotation by the pin tumblers 37; that is, the knob 16 cannot be rotated to swing the bolt out of engagement with the door frame 11 except when the key 38 is inserted in the look, as shown in Fig. 4. It will also be apparent that the key 38 need not be rotated in the lock to unlock the knob, but need simply be inserted in the lock, since, when the key is inserted in the lock, the key barrel is free to rotate; and when the key barrel is unlocked, the

knob which is controlled thereby is also un-- locked and free to rotate.

It will be seen from the above description that the angle through which the knob 16 may be rotated is limited by the ends of the spaced legs 21, which project through the arcuate slots. 16, and that the angular movement of the knob is also limited by the notch 29 formed in the swin ing bolt 25 and the cooperating pin 30. twill, therefore, be

seen that, if desired. the notch 29 and the cooperating pin may be omitted.

From the above description, it Will'be apparent that I have devised a key-controlled knob for operating a swinging bolt, having a lock mounted within theknob for locking the knob against rotation, thus providing a very satisfactory locking means, adapted to be used upon sheet metal locker doors and for similar uses. But it"will be apparent that my key-controlled knob is not limited in its use to the operation of swinging bolts rigidly secured to the same.

I have not attempted to illustrate or describe the various modifications of the construction which may be adopted within the scope of the appended claims.
