have inveiited 'certain n'e'wand Liseful Im- 5 proveii'ieiitsfinSaety Padlocks (iforvwhich legs of the shackle in 'which spring actuated tuinblers arefarranged lso as Eto' Lslide in'aXial direction. `The tuinblers are secured against rotation in theirhol'es.

In the drawings affixed to this specification and forming part thereof, anA embodinient of my invention is "illustrated "diarggraminatically by way of example. In the drawings:-

Fig. l is a perspective view of my improved padlock,

Fig. 2 is a perspective View of the key for opening the padlock,

Fig. 3 is anelevation, and Fig. 4 an end elevation of the shackle, Figs. 5 and 6 are sectional pla-n views of the locln and key, illustrating the parts in locking and unlocking position, respectively, Fig. '7 is a section on line A-B in Fig. 5. The padlock comprises a solid block b ot metal which is provided with two parallel. bores tor receiving the two legs of the shackle 0. VOne leg c of the shackle is provided with cylindrical recesses al. In the device illustrated, six bores for the tumblers CZ are provided in the metal block b which bores are at right angles to the legs of shackle c. The tumblers are provided with longitudinal slots f', as best seen in Figs. 5 and 6, in which are inserted pins f so as to i liiiiit the strokeofltliel tuinbleisand' prevent them from turriiingi'n theirlblores. l At' l'the rear of every 'tumblerfa springe fis inserted `in the bore whichiorces th'ejltumbler to the outside as 'tarl as perinittedfby "pifnl, 'In' this position, l"the outer rends of t-h'etuinlilis are in line with' the I"fa-ce' vof lilo/5b.

moved into further, at its upper lend, provided'with a hook g which is adapted toeiigage a slot t'inthefblo'ck b. k y.

nWhen itis desired to' unlock "the "padlock, the hook g 'is inserted into the slot zfand the plate g is 'forced toward thebloc'kla yso i tliatjtieypins fgj force 'chef tumbler-S d finto the Ablock "b The length of pinsjr/ is such that the tumblers d are placed in unlocking position.

Owing to the construction quantity production is very simple. The tumblers Z and the shackle c are made ot round iron bars, the recesses itor receiving the tumblers and legs of the shackle being bored. The manufacture is as follows:

First the several keys corresponding to the various combinations are made, whereupon the holes for the legs of the shackle o are bored in the block b and the shackle inserted into the holes so as to be in its lowest position. Now, the holes for receiving the tumblers b are bored, which at the same time produces the recesses CZ in the leg c of the shackle. Now, the shackle c is removefhthe springs e and the tumbleii's d are inserted and pins f are liXed in position. The key g` is now placed in position so that the tumblers d are forced into the block in conformity with the. length of pins g. In this position of the tumblers, a drill having described,

llt)

the same diameter as the leg c is inserted into the bore for receiving this leg and all the recesses c of the tumhlers are lbored cxactly in the required position.

I claim:

1. In a padlock, a solid meta-l block, a shackle, two parallel passages in said block receiving the legs of said shackle, a plurality of parallel bores in said block crossing one leg of said shackle, locking pins of circular cross section slidahle within said bores, means to prevent the said locking pins from rotation and means to limit the stroke of the loclng pins, springs 'thrust-ing said locking pins into their locking position, recesses in the leg of the shackle adapted to engage the said locking pins and a recess in an intermediate part of the said locking pins adapted to register in an intermediate posit-ion of 'the locking pins with one ot the passages of the said block receiving the shackle.

2. In a padlock, a solid metal block, a shackle, two parallel passages in said block receiving the legs of said shackle, a plurality ot' parallel hores in said block forming two rows located on the two sides of the leg of the shackle crossing one of the said legs on its both sides, locking pins ot' circular cross section slidalole within said hores,l means to prevent the said locking pins from rotation :ind means to limit the stroke of the locking pins, springs thrusting said locking pins int-o their locking position, recesses in the leg of the shackle adapted to engage the said .locking pins and a recess in an intermediate part of the said locking pins adapted to register in an intermediate position of the locking pins with one of the passages of the said block receiving the shackle.

3. In a padlock, a solid metal block, a shackle, twoi parallel passages in said block receiving the legs of said shackle, a plurality of parallel bores in said block crossing one leg of said shackle, locking pins of circular cross section slidalole within said hores, means to prevent the said locking pins from rotation and means tioi limit the stroke of the locking pins, springs thrusting said locking pins into their locking position, reccsses in the leg of the shackle adapted to engage the said locking pins, a recess in an intermediate part ofthe said locking pins adapted to register in an intermediate position ot' the locking pins with one of the passages o the said block receiving the shackle, and a slot in the said block adapted to he engaged by a hooked part of the key.

4. In a padlock, a solid metal block, a shackle, two parallel passages in said block receiving the legs or' said shackle, a plurality7 of parallel hores in said block forming two rows located` on the two sides of the or' the shackle crossing one of the said legs on its both sides, locking pins of circular cross section slidalole within said hores, means to prevent the said locking pins from rotation and means to limit the stroke of thc locking pnsf, springs thrusting said locking pins into their loeking position, recesses in the leg of the shackle adapted to engage the said locking pins and a recess in an intermediate. part of the said locking pins adapted to register in an intermediate posit-ion ot the locking pins with one of the passages i' of the said block receiving the shackle, and a slot in the said block adapted t0 loe engaged by a hooked part orl the key.

In testimony whereof I atiix my signature in presence of two witnesses.
