PADLOCK.

SPECIFICATION forming part of Letters Patent No. 443,537, dated December 30, 1890. Application filed March 22, 1890i Serial No. 344,948. (Model.)

To all whom it may concern:

Be it known that I, ALFRED T. PERRINE, a citizen of the United States, residing at Cincinnati, county of Hamilton, State of Ohio,

have invented a new and useful Improvement in Padlocks, of which the following is a speciiication.

My invention has for its object a structure of padlock which combines the advantages of 1o being burglar-proof and weather-tight with those of cheapness,compactness, and elegance.

Referring to the accompanying drawings, which form a part of this specification, Figure I represents a padlock which embodies i 5 my invention, the cap or front plate being removed and the lock being shown in its closed condition. Fig. II represents the same lock in its open condition. Fig. III represents the key and the gang of tumblers detached.

zo Fig. IV represents the parts of the key-hole guard detached. FigV represents in its unlocked condition a modification of the form shown in the previous iigures. Fig. VI is a detached representation of the modified forms 2 5 of hasp and tumbler shown in Fig. V. Fig. VII is an edge view of the group or gang of tumblers.

The case 1 has preferably the form of a truncated lunette, whose sides 2 are prolonged above the top plate 3 in the form of lugs or cheeks, of which the cheeks 4, receiving a pintle 5, constitute the hinge 4 5,which attaches to the case one end of arcuate hasp or shackle 6, whose other end terminates in 3 5 a double hook 7 8, whose engagement in gate i), between the inturned teeth 10 1l of the oscillating tumblers or rack a b c d operates to fasten the lock. Cheeks 4.', similar to the cheeks 4, serve to guide the hooked extremity 4o 7 8 of the said hasp 6 through opening 12 in the top plate 3 for engagement with the tuinblers in the manner stated. A like opening 12 admits a spur or tail 6 from the hinged end of the hasp, against which engages a spring 13, (held in stump 13,) which, the instant that the hooked end of the hasp becomes liberated from the tumblers, throws the hasp to the wide-open position shown in Fig. II.

Four tumblers are here shown; but they 5o may be of any desired number greater or less. A single pivot 1i serves as the fuicruin about which all the tu inblers oscillate. Each tumbler is pressed and held to its normal or locked condition (shown in Fig. I) byaspring 15, whose free end bears against the concave wall 16 of the case.

The tumblers have all the same identicalprofile except in respect to the heel 17.. The downward extension of each heel is slightly different to every other, and, the wards 18 of 6i the key 18 having a corresponding indentation, the elevation of said heels by the upthrust of the key brings all of the tumblerteeth in exact alignment, and thus liberate-s the hasp.

To enable the insertion of the key for unlocking without subjecting the lock to the liability of entrance of water, e., the bottoni of the case has two lips 19, between which is the key-hole 20, in the form of a narrow slit 7o just large enough to admit the end of the key, which latter acts wholly by thrust. The several tumblers are all arrested at the same locking position by a stop or stump 21.

For additional protection against the en- 7 5 trance of water and other foreign matters through the key-hole, I provide a guard or stump 22, whose edge 22 nearly closes the passage at the ends of the tumblers. This guard 22 is just sufficiently distant from the 8o case-iioor to receive a shutter 23 of spring steel. This shutter is capable of being slid endwise between the said guard and the caseiioor, so as to close the key-hole on its inside,

as shown in Fig. I, or of being brought to the 8 5 position shown in Fig. II, so as to open the key-hole and permit the insertion of the key. With this object in view a slot 23' in said shutter receives the eccentric wrist 24. on a shaft 25, whose inner extremity is journaled 9o in a stump 26. The pressure of the springshutter 23 against a shoulder 25 of said shaft 25 draws said shaft inward and causes the fiat portion 25 to occupy the slot 27 in the case-iioor, so as to prevent rotation of said shaft, and by so doing to lock the said shutter to either the effective or the non-eective position. The said shaft 25 terminates outside the case in an eye or handle 28, by which the said shaft can be pulled outward against roo the inward stress of the shutter 23, so as to bring the wrist 24 in the slot, and thus make l 1 i I possible the rotation of the said shaft, so as to protract or to retract the shutter, upon which the operator releases the shaft, and the resilience of the shutter drawing the shaft into the case brings its flat portion 25" back into the case-slot 27 and locks the shutter to such position.

The stump 2G is further utilized to support the spring 13 and subject the same to a severe tension when the tail G brings it to the greatly-bent condition shown in Fig. I, in order that the momentthe tumbler-gates are all brought in alignment by the key the spring 13 will act to throw the hasp 0 suddenly into the open or unlocked condition shown in Fig. II. This action may be further aided by the point of the shaft 25 being caused to press forcibly against the spring 13 in the locked condition, so as to add the resilient force of the spring-shutter 23 to that of the spring 13.

Shoulders (5 6 til" in the hasp 6 serve to prevent the entrance of dirt and moisture through the openings l2 12 in the locked condition of the device. A valley or depression l in the top of the case serves 1o afford room for the staple or other object.

I reserve the right to modify my said invention while preserving its essential characteristics. For example, the top of the case at the hinge end of the hasp may be imperforate and have a closed valley, as shown at 30 in Fig. V, and an external spring 3l, which bears against the shoulder G, may be substituted for the internal spring 13. This form of course supersedes the necessity of employing a tail 6', which is therefore omitted.

An eye 32 in association with the form of tumbler shown at 33, Figs. V and VI, may be used instead of the double hook T 8.

The handle 28 of the shaft 25 may be given the form of an eye, as represented, which may receive a chain 34, by which the lock may be suspended from the pouch or other article to be fastened, thus giving the semblance of an ordinary fixed projection from the lock.

It will be seen that the tumblers a b c d are interchangeable, thus enabling the same lock to be varied to t twenty different keys.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

l. In a padlock, the combination, with lu nette-formed case l, of the hasp G, having the double hook 7 8, the gang of rack-tuniblers a ZJ c d, having the doubly-guarded gates 9, the guard 22, and the narrow key-hole 2O between the lips 19, as set fort-h.

2. In a padlock, the combination, with the case l, having the key-hole 20 in its floor, of the guard 22, the slidable spring-shutter 23, and the selflocl;ing eccentric shaft 25 for operating said shutter, substan tially as set forth.

3. In a padlock, the combination ot hasp 6, having the tail 6', the retractingspring 13, the stump 26, the spring-shutter 23, and the shaft 25, as set forth.

ALFRED T. IERRINE.
