LOCK

Filed Aug. 14, 1929 J K Waffel.

attorneys Fatented Bec. 30, i939 airs S iaaasn Junren K. WARREN, or saneren, Mississirrr noci;

Application filed August 14, 1929. v .Serial No. 385,729.

The present invention seeks to provide a very simple lock which will eectually hold the parte to which it is applied and resist improper efforts to release the same but may e be very readily released by the use of a proper key. The invention is illustrated in the accompanying drawing and will be hereinafter Yfully set forth.

in the drawing:

o Figure 1 is a perspective view of a lock embodying the invention,

Fig. 2 is a longitudinal section of the same,

Fig. 3 is a transverse section on the line 3 8 of Fig. 2, and

5 Fig. a is an enlarged detail of a portion of the hasp.

Y The .invention relates more particularly to locks oi the padlock type and employs a hasp in the form of a cable 1 consisting of a central core 2 of iiexible material, such as a flexible wire7 and a. plurality of disks 3 mounted upon the core and extending the full length of the same. As shown most clearly in Fig. 4, the disks are conical in form and have their apeies cut away to provide a central opening through which the core passes, the conical form of the disks'permitting them to nest closely so that, in e'ecta they form a continuous outer sheath for the core. The hasp has one end secured permanently in the body of the lock and its other end inserted in a longitudinal passage 4 to be engaged by the locking dogs7 as will be presently set forth. The hasp may be of any desired length and the passage i may extend entirely through the lock body so that objects of any size may be secured. it being possible to draw the hasp closely around the parts which are to be locked together'. In the smaller locks, the tree end of the hasp will be housed in the body, as shown in Fig. 2, but in the larger locks, the hasp will extend entirely through the body. The lock body consists of two mat ing sections 5 and 6 of semi-circular form in cross section, the hasp being anchored in the section 5 and the passage e being formed in the meeting faces ot the sections, as shown in Figa 3. The meeting faces of the two sections are `formed with longitudinally extending '3 recesses or cavities which, when brought toA gether, definea keyway 7 and a chamber 8 in 'which the locking dogs 9 are mounted. As shown most clearly in Fig. 2, the locking dogs 9 are in the form of bell cranks each having one end 10 tapered so that it will readily enter between two adjacent disks 8 and thereby form a locking engagement with the hasp which resists attempts to pull it from the lock body. n The opposite ends of the bellcranks project into the keyway, as shown at 11, and torsion springs 12 coiledk around the pivots of the respective bell cranks andv engaged with the same and Awith the wall of the chamber 8 serve to hold the cranks normally in engagement with the hasp, as shown in Fig. 2. "When it is desired to release the hasp, a key 13 is inserted in the keyway and will rock the ybell cranks out of engagement with the hasp so that the hasp may then be` withdrawn. The key is a flat elongated plate having flanges 14 along one edge whereby it may be guided into and held by the keyway, and along its opposite edge is formed with a series oi notches 15 presenting lugs or shoulders 16 adapted to bear against the outer ends of the bell cranks to rock the same. It will be noted that the outer arm of the innermost bell' crank is longer than the outer arm of the outermost bell crank and the edge of the key is correspondingly tapered or formed on an oblique line so that the end of the key will pass the iirst bell crank without actuating the same and the active lugs orn the key will engage the respective bell cranks simultaneously. When the key is withdrawn, the bell cranks automatically assume their normal positions and then when the hasp is pushed into the lock body it will ride past the tapered ends of the bell cranks which will yield to the movementbut when the movement ceases the bell cranks will enter between adjacent disks, as clearly shown in A cylindrical casing 17 is Yfitted about the body after the pivots 18 of the bell cranks have heen inserted and their ends upset to hold the sections of the body together. This outer casing or shell is formed of hard steel and has one end 19 entirely closed, except for a narrow key opening while at the other end it is open to accommodate the hasp but is formed with an annular flange 20 fitting over the end ofthe body and retaining the casing thereon. The casing will t some what loosely about the body so that, while it eii'ectively holds the sections together, it will rotate about the body if an attempt be made to cut through the shell or twist it off .in order to gain unauthorized access to the lock to release the parts secured. The bell cranks which `forni the active hasp holding elements are large enough to possess strength sufficient to hold the hasp in locked position but at the same time are not so large that they might be actuated by the insertion of a wire or other similar device in the keyway of the lock. The notches in the key will be varied and the positions of the dogs shifted in the various locks accordingly so that no key will it two locks. It will. be noted easily that the dogs very effectually hold the hasp against Withdrawal, as the harder the hasp is pulled the more `firmly do the dogs engage or bite between the cones.`

Having thus described the invention, I claim:

l. A lock comprising a lock body having a longitudinal key-way and a passage parallel with the keyway, a hasp having one end anchored in the body and its opposite end engageable in said passage in the body and including a series of closely nested disks, bell cranks mounted within the body and alined longitudinally thereof between the keyway and said passage and cach having one end presented to the hasp to engage between the i disks thereof and the opposite end disposed within the keyway in the body, and yieldable means for holding the bell cranks in engagement with the hasp.

2. A lock comprising a lock body consisting of mating similar sections, a shell surrounding the sections, the opposed faces of the body sections presenting a longitudinal hasp-receiving passage, a keyway, and a chamber between the keyway and the hasp passage, locking dogs pivoted in said cham.- ber and each having one end disposed within the keyway and its opposite end disposed in the hasp passage, and springs engaged with the dogs and holding thein normally in op i' erative position.

In testimony whereof I atlix my signature.
