Laminated padlock body with incorporated band-forming slab

Claim 2

In a lock body, a series of relatively similar, superimposed laminations of generally rectangular outline, a band forming slab of generally rectangular outline in superimposed relation with said lamination but larger than the latter so that the face portions of the slab project outwardly of the exposed faces of the laminations whereby said slab may function as a bumper, the series of laminations having lock mechanism housing cavities therein and the slab having cavities complementary to the lamination cavities, and means for securing together to form a unitary body all of the laminations and said slab.

Claim 3

The lock body recited in claim 1 wherein the laminations are formed of a hard metal and the slab is formed of a softer, more resilient material.

Claim 4

The lock body recited in claim 1 wherein the slab is formed of a material relatively softer than that of the laminations and an exposed surface of the slab bears identifying indicia and said securing means are elongated members which extend through all of the laminations and the slab and tightly unite them in super-imposed relation.

Claim 5

A padlock, comprising: a body, the major portion of the body being formed of a plurality of suPerimposed, secured together laminations; a band-forming slab underlying the laminations and secured thereto and having face portions projecting outwardly of corresponding face portions of the laminations to provide bumper areas, some of the laminations and the slab being formed with registering cavities to house lock mechanism; a shackle vertically reciprocal relative to said body from a retracted position to a projected position, said shackle having a long leg slidably accommmodated by said body and greater in length than the height of the body so that, when the shackle is in its retracted position, the lower end portion of said long leg projects beyond the normal base of the body; and a cup depending from the slab to accommodate said projecting portion of the long leg and its appurtenances.

Claim 6

A padlock, comprising: a body, the major portion of the body being formed of a plurality of suPerimposed, secured together laminations; a band-forming slab underlying the laminations and secured thereto and having face portions projecting outwardly of corresponding face portions of the laminations to provide bumper areas, some of the laminations and the slab being formed with registering cavities to house lock mechanism; a shackle vertically reciprocal relative to said body from a retracted position to a projected position, said shackle having a long leg slidably accommmodated by said body and greater in length than the height of the body so that, when the shackle is in its retracted position, the lower end portion of said long leg projects beyond the normal base of the body; and a cup depending from the slab to accommodate said projecting portion of the long leg and its appurtenances.

Claim 7

The padlock of claim 4 wherein the shackle is U-shaped and includes a short leg in addition to said long leg, and external portions of the shackle are covered by a guard.

Claim 8

The padlock of claim 5 wherein the long leg appurtenances include a pressure spring whose projecting end portion is housed in said cup, and the shackle guard is a shroud-like member carried by the upper end portion of the body.
