Abstract
Abstract To provide a metallic protector for substantially enveloping the major exposed portion of a retracted and locked padlock shackle an eccentrically shaped guard is affixed to the end portion of the padlock body in covering relation to the normally exposed portion of the shackle. The outer end of the guard is slotted so that when the shackle is unlocked and reciprocated outwardly for staple eye engaging or releasing purposes, it will freely move outwardly through the slotted end of the guard while the guard remains immovably affixed to the padlock body.

100 words
In combination: a padlock body having first and second ends; a lockable shackle reciprocatably carried by the body and projecting from the first end thereof, said shackle having a pair of legs, both of which are extended into the padlock body when the shackle is in its inwardly reciprocated position; a thimble carried by and projecting beyond the second end of the body and in alignment with one of the legs of the shackle; and means extending into said thimble and reacting against one of the legs of the shackle to automatically reciprocate the shackle outwardly when it is unlocked.
Claim 2
Dependent Claim
100 words
In combination: a padlock body having first and second ends; a lockable shackle reciprocatably carried by the body and projecting from the first end thereof, said shackle having a pair of legs, both of which are extended into the padlock body when the shackle is in its inwardly reciprocated position; a thimble carried by and projecting beyond the second end of the body and in alignment with one of the legs of the shackle; and means extending into said thimble and reacting against one of the legs of the shackle to automatically reciprocate the shackle outwardly when it is unlocked.
Claim 3
Dependent Claim
48 words
The combination recited in claim 1 wherein one of the shackle legs is a short leg and the other shackle leg is a long leg with the means which extend into the thimble reacting against the long leg of the shackle which is in alignment with said thimble.

The combination recited in claim 1 wherein the shackle is non-removably reciprocatably carried by the body.
Claim 6
Dependent Claim
40 words
The combination recited in claim 1 wherein the body has a shackle enveloping guard affixed thereto which reciprocatably movably receives portions of the shackle so that the shackle, when unlocked, may reciprocate while the guard remains affixed to the body.
Claim 7
Dependent Claim
58 words
The combination recited in claim 5 wherein one of the legs of the shackle is a short leg which moves free of the body when the shackle is unlocked and reciprocated outwardly and the guard has a mouth therein registering with the freed short leg of the shackle when the shackle is in its unlocked, outwardly reciprocated position.
Claim 8
Dependent Claim
228 words
In combination: a padlock body having first and second ends; a U-shaped shackle extending reciprocatably into the padlock body and including a short leg reciprocatable free of the first end of the body and a long leg which, when the shackle is in its retracted position extends beyond the second end of the body; means housed within the body for locking the shackle in its retracted position; a guard secured at its inner end portion to the first end of the body and substantially enveloping the shackle when the latter is in its retracted position, said guard being formed with openings wherein portions of the shackle are protectively lodged when the shackle is in its retracted position but permitting outward projections of the shackle relative to the first end of the body and the anchored guard when the shackle locking means is released, the guard, in a side portion thereof adjacent the short leg of the shackle, having a mouth therein; a thimble carried by and projecting beyond the second end of the body and in alignment with the long leg of the shackle and receiving the extended inner end portion of the latter in the retracted position of the shackle; and a spring extending into said thimble and reacting against the long leg of the shackle to automatically project the shackle outwardly when the latter is unlocked.
Claim 9
