the following is a specification.
Thisinvention relates t0 padlocks and it consists in thevnovel features hereinafter described and claimed.
An object of the invention is to provide a lock of simple and durable structure which may be used for all of the purposes intended `for a pad lock and with this object in view the structure comprises a casing provided at one side with a key opening. A shackle is slidably mounted 1n the upper portion of rthe. lock casing and one side of the shackle is permanently retained in the lock casing and may turn therein. A spring is located within the lock casing and bears against the longer side portion of the shackle and is under tension with a tendency to hold the shorter end of the shackle away from the lock casing. Gripper members are pivotally mounted in the lock casing upon a pivot common to both and both of these members are provided at their lower portions with outstanding curved pins around which coil springs are placed. Longitudinally curved tubes are located in the lock casing and receive the outer portions of the said pins. The lower portions of the said gripper members are located at the opposite sides ot the key opening in the lock casing and consequently when a key is inserted through the said opening and turned it will swing the gripper members whereby their active or work engaging ends will disengage notches which are provided at the shorter end portion of the shackle of the lock.
In the accompanying drawing Figure 1 is a side view of the lock.
Fig. 2 is a sectional view of the same.
Fig. 3 is a transverse sectional view of the same cut on the line 3-3 of Fig. 2.
Fig. 4 is a side view of a key which may be used in conjunction with the lock.
The lock comprises a casing 1 which is of conventional shape and which is provided at one side with a key opening 2. The casing 1 is provided at its top side with space openings 3 and 4 through which the side portions of a shackle (hereinafter described) may pass. Gripper members 5 are located within the casing l and pivotally mounted upon a pivot bolt which passes transversely through both of the saidgripper members at a point between the ends thereof. The gripper members 5 are providedr at their outer sides and in the vicinity of their lower' ends with longitudinally curved pins 7. These pins are slidably received in longitudinally curved tubes 8 which are fixed with relation to the lock casing 1.- The pins 7 and tubes 8 are curved on arcsI which are struck 'from the center ofl the bolt` 6. Springs 9 bear at their inner ends against the sides of the Gripper members 1 and surround the pins I and are received in the tubes 8. The outer ends of the said springs bear, against portions of the casing l1. The springs 9 are under tension with a tendency to hold the lower portions oi' thegripper members 5 toward each other and the lower portions ot' the said members are located at the opposite sides of the keyopening 2 which is provided in the casing 1.
The lock also includes ashackle 10 one endof which is longer than the other and the long end portion oit' the said shackle passes through the opening 3 whileV the shorter end portion of the said shackle may pass through the opening 4. lhe longer end portion of the shackle 10 is slidably and turnably mounted in the opening 3 and the said portion is provided at its inner or lower extremities with an outstanding shoulder- 11 adapted to limit the sliding movement oi the shackle with relation to lock casing. The longer end portion of tbe shackle 10 is further provided with a socket 12 which receives a pin 13 mounted upon a portion of the casing 1. A spring 14 surrounds the pin 13 and enters the socket 12, one end of the said spring bearing against a portion of the casing 1 and the other end thereof bearing against the upper wal] of the socket 12. The spring 111 is under tension with a tendency to normally hold the shoulder 1] in engagement with the inner surface of the tractor of lthe casing 1. The shackle 10 is provided at its upper end portion and at the opposite sides thereof with notches 15 which are adapted to receive the upper' ends of the gripper members 5 when the shorter end portion is inserted through the opening' 4 of the easing 1 and the extremity of the shorter end portion of the said shackle 10 is passed between the upper ends of the gripper members 5.
When the shackle 10 is in a closed psithe loWer portions of the gripper members j` andispreadtthe same against thevr tension "ofhe s'p1'`in"gs'9.'
