PADLOCK.
Application led January 2, 1923.
This invention relates to padlocks, and has for its object the provision of an improved padlock which is so constructed and arranged as to enable it to be readily manufactured in quantities at low cost, and which lock is more secure against unauthorized manipulation than prior devices of this character.
A further object of the invention is to provide a padlock in which the locking arm of the shackle is securely held in locked position in the lock body by a locking bolt adapted to be moved laterally into and out of engagement with said shackle arm, or longitudinally for automatic locking engagement, said dog and shackle arm having interlocking flanges or shoulders which effectively prevent accidental or unauthorized disengagement thereof.
Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.
In the drawings, which represent one suitable embodiment of the invention, Fig. 1 is a front elevation of my improved padlock; Fig. 2 is a plan view of the base of the lock body; Fig. 3 is a Vertical sectional view of the lock; Figs. 4 and 5 are cross sectional views, taken on the lines 4 4 and 5 5, Fig. 3, respectively; Fig. 6 is a view similar to Fig. 5, but showing the locking dog in its alternate or unlocking position; Fig. 7 is a cross sectional view, taken on the line 7-7, Fig. 3 and showing the locking levers in locking position; Fig. 8 is a similar view, showing the levers in release position; Fig. 9 is a vertical sectional view of the lock body; Fig. 10 is a vertical sectional view of the rotatable plug; and Figs. 11 and 12 are similar views, respectively, showing the locking levers in release and locking position.
Referring to the drawings, the lock comprises the usual body 1, preferably a single metal member, solid except as hereafter noted, and of any suitable form. Said body is provided with the usual shackle 2, which is slidably secured therein in such manner that the shorter arm 3 may be longitudinally moved into and out of locking engagement in an opening 4 in the body 1, said shackle also having turning movement about the axis of the longer arm 5 when in unlocked position, as is usual.
The longer arm of the shackle is slidably Serial No 610,201.
and rotatably secured within another opening 6 in the lock body by a suitable pin 7, extending into or through the body at any suitable point. Said pin engages in a lorigitudinally extending groove 8 in the shackle arm 5, so that the shackle has sliding, longltudinal movement within the limits of said groove. At the base of said groove, the shackle larm 5 is provided with an annular recess 9, to enable the shackle to be freely rotated about said arm as an axis when said shackle is in outer, unlocked position, as indicated in dotted lines, Fig. 1. Said shackle is normally forced outwardly to this unlocking position by a spring 10, suitably arranged within a longitudinally extending opening in the lower end of shackle arm 5.
The shorter arm 3 of the shackle is adapted to be held in locked position in opening 4 by a suitable locking bolt 11, which is adapted to be laterally moved into and out of engagement in a suitable recess 12 in the lower end of said shackle arm, as will later appear. Said bolt is suitably arranged within the upper, enlarged head portion of a substantially cylindrical plug 13, which is suitably secure-d within a centrally disposed opening 14 extending longitudinally through the lock body 1. Said bolt is slidably secured within a diametrically disposed opening 15 in the enlarged head portion of the plug by a pin 16, engaging in a longitudinally extending groove 17 in said bolt, the latter being normally forced outwardly by a spring 18 suitably arranged in the opening 15, as indicated in Fig. 3.
rThe plug is secured within opening 14 by screw threads 19 on its enlarged head por` tion, which screws into the upper, enlarged end portion of opening 14, the threads being so arranged that when the plug is screwed in until the plug shoulder 2O engages shoulder 21 of the wall of the opening, the locking bolt 11 will be in alignment with the shackle arm opening 4. Adjacent said opening the material of the lock body is recessed, to form a passage-way 22 between openings 14 and 4, and a cavity 23 at one side thereof, into which cavity 23 the locking bolt may be laterally moved out of engagement with shackle arm 3 when it is desired to unlock the device.
5. In a padlock7 a casing provided with a shackle receiving bore and a seat to receive a locking mechanism, a unitary locking mechanism mounted in said seat, said mechanism comprising a reciprocable bolt the end of Which projects into the shackle bore, and key operated means to control said bolt, comprising a key plug and tumblers controlling said plug.
6. In a padlock, a casing provided with bores extending through opposite faces thereof, one of said bores being adapted to receive a shackle, a unitary locking mechanism mounted in the other of said bores, said mechanism comprising a locking bolt and key operated means to control said bolt,
said bolt being adapted to project into said 20 lirst named bore and engage the shackle.
In testimony whereof I hereby ailix my signature.
