y Letters Patent No, (STAM, dated Ain/tst (i, 1867.
IMPROVEMENT IN PADLOGKS, cito.
TO ALL WHOM IT MAY CONCERN:
Be it known that l', WILSON BOIIANNAN, of Brooklyn, in the county of Kings, and lState of New York, have invented an Improvement in Locks; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in whichp Figure 1 is a front view of a padlock having my improvements applied to it.
Figure 2 is a similar vien' of the same parts, showing the shacklelocked in place.
Figure 3 is an enlarged section through the lock taken in the plane indicated by red lines x J: in tig. 1.
Figure 4 is an enlarged section view, showing the construction of the parts which are applied to and move with `the bolt frame.
Figures 5 and 6 show modified forms ofthe lock mechanism.
Figure 7 is a perspective view of the key. Similar letters of reference indicate corresponding parts in the several figures.
l This invention relates to certain noveliimprovementson burglar-proof locks, wherein notched sliders are employed in conjunction with a straight-edge knife or plate, so arranged that when the notches in all of the sliders are brought in a plane with the knife by the insertion of a flat key, the lock-bolt can be freely moved.
The nature of my invention consists in applying the knife or safety-guard of the lock that its straight edge will approach and recede from the notches in the sliders in a pla-ne parallel to the edges of these sliders, so as always to enter said notches squarely, notwithstanding the fact that the slidersare moved, with their bearing-plate, in the arc of a circle, as will be hereinafter described.
To enable others skilled in the art to understand my invention, I will describe its construction and operation.
t In the accompanying drawings, figs. ,1, 2, 3, and 4, A represents the lock frame of a padlock, A is the face-plate which is shown in iig. 3, and B is the shackle which is pivoted to the stud B2, and constructed with a recess or slot throughout its nose Bl for receiving the hooked holt u of the oscillating frame, C. This frame A and its shackle B *may be constructed in a manner similar to like parts of padlocks heretofore made. The frame Gis constructed with the hooked lock a upon its upper extensom'ivhich enters the slot in the nose ot' the shackle when the latter is locked, as shown in tig. 2. This frame C is pivoted toa stud, p, on the inside of the back-plate of the lock frame A, so that it will oscillate freely about said pivot a suiiicient distance to lock and j, f unlock the shackle. A recessed elevation or boxed bearing', d, is secured to or formed upon the plate C, for the purpose of receiving and serving as a guide and holder for the notched sliders e e. The circular end of this 'boxed bearing d is slotted, as shown in iigs. 1 and 2 and 3, for the purpose of receiving through it a thin key, K, of the kind shown in iig. 7, so that the Wards S of this key will push back in several sliders the required distances to allow of their respective deep notches to be brought in the same line. This circular end of hearing ol passes freely through the face-plate A', as shown in fig. 3, and consequently forms an outer pivotal bearing for serving, in conjunction with the inner pivotal bearing@ as a means of holding the plate C in place within r the lock frame. The sliders are made with false and true not-ches in them, in the usual manner, the false notches being veryT short, while the true notches are of .suilicient size to admit of their receiving the straight edge of a movable platc,f, and to allow of the locking and unlocking of the shackle. Each slider is acted upon hy a.
spring, b, that is applied to a ban-c, so as to press the slider up against the inside of the slotted face-plate d when released from the platef. That edge of the plate or knife" f which is nearest the notched edges ofthe sliders is straight and parallel to these edges, as shown in iig. 4. It is fitted to slide freely in grooves that are made through the boxed bearing d, and it receives a movement toward and from the sliders e in planes parallel thereto, so that when the shackle is unlocked., as in iig. Q, the straight edge of the plate or knife f will enter squarely the true notches in all the sliders, and when the shackle is locked the platefrecedes from these sliders and assumcsthe position shown in figs. 2 and 4. The plate or knife is pivhted to two arms, g and z. The
shortest arm, g, is pivoted to the frame C at k, and to the plate fat t', andthe arm 11. is pivoted to plate fat t', and to the frame C at Z. The outer end of this arm or lever L is slot-ted longitudinally,and through this slot a Stull, j, projects, which is secured to the back-plate ofthe lock frame. rThe length ofthe slot through the outer L end 'of arm l1. is such as to allen' the plate C to have a free vhratingimo'v'ement about its fixed pivotj.1 for locking and unlocking the sharkle.- `It is this slotted arm h, arranged as described, that causes the plate or knife f to amer 2 approach and recede from the sliders e in parallel planes, as to enter the true notches in these sliders when the shackle is-unlocked. The spring E on stud E has a friction-catch formed on its end,rwhich presses upon the tooth m that is formed on the pla-telvC, and thus holds the plate C either in a locked or an unlocked position. The spring D, whichis also applied toithe stud F, is used for throwing out the nose of the shackle when this nose is released -from the hooked bolt a, :is shown in lig. 1.
In fig.l 6 I have shown aimode of giving a parallel movement to the plate or knife f? by u single slotted lever, which is pivoted to the locking-plate C and to this knifefz, and guided by a stationary stndhiz. This knife, f2, is connected to the frame C by means of two pins' passing through oblique slots, so that when the frame C is moved said slots will gnidethe knife up to and from the true notches in the sliders.
In g. 5, a slotted vibrating arm, t, and a vibrating arm, g, are piroted to the plate or knife f1 in such manner as te vibrate entirely through the true notches in the sliders e', both inlocking and in unlocking the bolt, thereby allowing tbe sliders to rise to their pinces after each movement of the plate, and preventing an 'impression being taken ofthe positions of the sliders when the bolt is unlocked.
In both of these modifications ofthe device represented in figs. 1, 2, and 4, it will be seen that the straight edge of the knife is guided into and out of the true notches in the sliders with a pai'allel'.nio\'ement, and that the said knife is supported by, and caused to move with its holt-plate about, the pivot thereof.
Having described my invention, what I claim es new, and desireto secure hyfLetters Patent, is-
1. In combination with an oscillating plater C, to which the notched sliders c are suitably applied, I claim the parallel moving plate or knifefettached to said plate and guide, substantilly as described.
2. The combination of the platc'or knife f, sliders e, and oscillating plate C, with a vibrating rlever-arm whieh is guided and controlled by a fixed stu'd, j, or its equivalent, substantially as described.
