Application mea member as, me, serial n. 156,370,
The present invention relates to a padlock the case of which has a U-shape'd form.
straight locking-bolt contained in one arm of the U portion and displaceable transversely therein.
The object of the invention is to rovide a pivotally mounted lever, the end o which engages the bolt, retaining the bolt in its with rawn position, when the padlock is open, by means of a spring and on the bolt being shot home actuating the catch consisting of a hook which holds the boltl in the closed the key belonging to the padlock.. Several embodiments of construction of the padlock ofthe present invention are shown in the accompanying drawings in which:-
Figure 1 is' an elevation of the padlock,
provided with a steel protected barrel, with thebolt shot home.
Figure 2 is anv elevation of the same padlock with the bolt withdrawn and the staple of a hasp, which is not shown, inserted lbetween the branches of the barrel.l
- Figure 3 vshows'one half of the barrel of the padlock with the locking mechanism, the
bolt being shot homand secured.
Fi re -4 shows the same half of the barrel a'nd ocking mechanism rwhen the bolt is i withdrawn.
Figure 5 is a modified form of construcf tion and' shows one half of the barrel o f the padlock when the locking mechanism is of a type which allows a at key to be inserted atone end. The bolt is inthe locked position.
Figure 6 shows the same half of the pada Figure 7 shows' one half ofv a padlock p the bolt is unlocked.
)two steel sheets stam ed into a U or branch 1 of the The. barrel of the padlock is composed ofl shape and pressed'intov hollow s ells, these being joined together b caps fitting tightly over the two ends of t e'barrel. l
A bolt 3 is movabl mounted in an `arm shaped barrel of the position and can only be releasedby is formed asa hook I lock barrel of Figure 5 with the bolt with.
'and in Germany my 12,1926.
padlock.` An openingl or slot 5 is. provided 1n the wall 4 of the second branch 2 of .the barrel opposite the .arm' or branch l, into which the front end 7 of the bolt 3 on the bolt being shot home. tween thev two the barrel is open. i
In order to secure a hasp, placed over a staple in the usual manner, the padlock with the bolt 3 withdrawn, is pushed over the staple 6 until thelatter is situated between the two arms or branches 1 and 2, as shown' in Fig. 2, when the boltl is pushed home, passingthroughV the opening of the staple alriid thus securing the hasp, which is not s Own.
The space bearms oi"v branches 1 and-2 of empty when kthe padlock is A lever' 9, f )ivotally mounted in the barv -relof thev vwhich lever engages within a slot provided padlock on a pin 8, the end'lO of in the-bolt 3, serves to move the bolt 3 backwards and forwards, as shown in `Figures 3 to 8. 'A plate 12, the forward end of whichv 3, is pivotallv mounted l(in a pin 11 fitted on )the lever 9'(Fig's. 3 and A. lug 14 is provided on the upperedge ofthe hook on the plate 12 whilst one'end 15 of' a leaf spring located on the` pin 8 bears against this lu'g 14, the other end 29 of the spring resting against the rear wall 16 of the barrel of the padlock.
When, the bolt 3 is ,pushed home,l the hook 13 on the late 12 engages the pin 17 secured on tlie barrel of t e padlock andis held in this position by the spring .15,V 292 The plate 12 in turn holds the lever 9toether 'with the locked bolt 3, as showngin ig. 3. e
The lpadlock' is opened by rotating the plate 12 about the pin 11 by means of a key 8 until the hook is raised oli' the pin 17. In its path of rotation` the key strikes the passes lever 9 which rotates about the. pin 8 and on further turning of the key thus moves the sion of the spring 15, 29, the end 10 of the lever 9 thus moving `the bolt'3 into the unlocked position as shownin Fig. 4. In this" position of the lever 9,-the wardsof the key ,N
rest in agcurved depression 19 in the edge of the lever 9 and'thus lock the latter. M When the keygis turned backwards, it
forces the plate 12 to the left, the lever 9 being movedalong with it and in turn driving the bolt 3 home. As soon as the end of the hook 13 comes in front of the pin 17 during the movement of the plate 12, the latter engages the pin 17 by means of the hook 13 under the action of the stretched spring 15, 29, whereby the lever 9 and the bolt 3 are secured in the locking position.
In the modification of the padlock shown in Figs. 5 and 6, two transverse walls 20 and 21 are mounted in the barrel and are provided with slots which in combination with a socket element 22 in the end 35 of the barrel, serve to guide a flat key 23. This key has a slotted edge 24 which, on turning the key, slides over a projection 25 on a partition 36 arranged between the partitions 20 and 21. A pin 28 is located on the lever 9, against which the rear half 29 of the leaf spring contacts. A forwardly bent lug 27 is provided on the front edge of the plate 12, the wide part 26 of the key catches under `this lug 27 when the key is turned thus lifting the plate 12 forward against the tension of the spring 15-29 so that the hook 13 is lifted off the pin 17. The lever 9 is now turned to the right by the branch 29 of the stretched'spring, moving the bolt 3 along with it and thus opening the padlock. Thf
late 12 is also moved a certain distance. The hook 13 slides with its lower edge on the pin 17, against which it is forced by the spring arm 15 pressing on the lug 14 on the plate 12. n
The movement .of the lever 9 required to open the padlock is limited by the lug 27 on the plate 12 contacting with the transverse wall 20.
The padlock can be closed without using the ke as it is merery necessary to move the bo t 3 by hand. vhe lever ,9 .is moved forward by this actionand the plate 12 moves along with it. As soon asthe under edge of the hook 13 reaches the pin 17, the
plate 12'is rotated downwards by the spring` arm 15 so that the hook 13 en ages the pm cured also b 17 and thus secures the locke position of the bolt 3.
The modified form of the adlock shown 1n Flgs. 7 and 8 can also be ocked without a key. lhe two arms of the spring are replaced 1n this type by separate springs 15 and 29. The spring 29 actuating the lever 9 4is arrangedso that it permanently tends to .move the lever 9' together with the bolt 3 into the open position. The spring 15 causes the plate 12 to' engage the in .17 and holds it in this position during t e locking operation. f
The locked position of the bolt 3 is lse- 0 a number of chubb tumblers 3Q, V1n addition to the late 12,'which are pivotall mountedV on t e pin 17 and are orced y the spring 31, bearing against a other,
The padlock is o ened by a suitable key fitting 1n the lock which disengages the plate 12 and the tumblers 30 are so positioned that the horizontal portion of the angular slots are covered and the pin 33 comes to rest in the forward end of the horizontal portions of the anglular slots covering each whereon t e lever 9 is immediately rotated backwards by the spring 29. The bolt 3 also partakes of this movement. When the key is removed, the, padlock can be locked by simply forcing the bolt 3 home. The lookin elements take up the positions shown in ig. 7, in which they are retained by the pin 33 which again passes into the upper arm of the angular slot 34 and the engaged hook of the plate 12.
The barrel of the padlock is preferably formed, in all the examplesof construction shown, of two pieces of late stamped out in the form of a letter and pressed into a hollow shell shape, which are connected together by two caps 37 (Figs. 1 and 2) fitted over the two ends of the barrel.
The space left between the two branches of the U is adjusted in each case to the thickness of the staple, so that adlocks of this type can be used for all t e metal fittings of a door consisting of hasps which are met with in practice.
