SPECIFICATION forming part of Letters Patent No. 380,961, dated April 10, 1888. Application filed September 26, 1881'. Serial No. 250,719. (No model.)
To all whom it may concern:
Be it known that we, DAVID \VAINE and ISAAC WAINE, subjects of Her Majesty the Queen of Great Britain, both residing at W'illenhall,in the county ofStafford,England, have invented certain new and useful Improvements in Padlocks, of which the following is a speoification.
This improvement in padlocks consists in a I novel arrangement, construction, and combination of certain of the parts as herein described, whereby padlocks are rendered selflocking and more secure, and advantages are obtained in the manufacture, as hereinafter set forth.
We will describe our invention by referring to the accompanying drawings, in which- Figure 1 is front elevation, and Fig. 2 a side elevation, of a padlock constructed according to our invention, the padlock being represented, as locked. Fig. 3 is a front elevation of the same unlocked. Fig. 4 is a front sectional elevation, and Fig. 5 is a side sectional elevation, of the same locked. Figs. 6 and 7 are front sectional elevations of the same, the lock being represented as unlocked in Fig. 6 and almost locked in Fig. 7. Fig. 8 is a plan of the casing of the same. Figs. 9 and 10representdetailsofthesanie. Fig. llshows the same lock with an enlarged shackle. Figs. 12 and 13 are part front sectional elevations, and Fig. 14 is a part side sectional elevation, and Fig. 15 a partial plan, of a modified form of padlock represented by the preceding figures; and Figs. 16 and 17 represent details of the said modification.
Referring first more particularly to Figs. 1 to 10, both inclusive, in all of which the same letters of reference indicate the same parts, A is the padlock-case, a is the key-hole, and B is the bolt of the lock projecting through a rectangular hole, a, in the top of the casing. The projecting part b of the bolt B is bowshaped, so as to form part (preferably one half) of a ring'shaped shackle, the other half, D, of which is made loose from the bolt B, and is hinged or jointed thereto by a pin, 6, formed on the bolt B passing into a hole, (1, in a side ear of the piece D. The end of the pin 0 is riveted over, so as to form a loose joint. The pin 6 is, for the purposes hereinafter described,
D form in cross-section a rectangle when together and fit in the opening 0 in the top of the casing. (See Fig. 8.) A shoulder, g, is provided at the neck of the bolt B and the loose bow D, which fits against the top of the casing when the bolt is withdrawn, as hereinafter described. The lower end, d, of the loose bow D is squared off, so as to bear against a stop, a in the case when the bolt is in its locked position.
The internal mechanism of the padlock -th'at is, that part of the bolt B which is inside the case and is operated on by the key z to shoot the bolt forward or to withdraw it, and the mechanism for maintaining the bolt in either its forward or withdrawn positions-may be similar to the mechanism employed in other looks. The internal mechanism represented by the drawings is similar to that used in some lever-locks, j being the tumbler turning on a fulcrum, k, and having at its free end a notch, Z, which engages with a projection, m, on the bolt B when the bolt is in its locked position. The tumbler is moved sidewise to free the bolt, and the bolt moved forward or withdrawn in the wellknown manner by turning the key i.
The operation of the padlock above described is as follows: WVhen the bolt Bis shot back into the case, (see Figs. 1, 2, 4, and 5,) the padlock is looked, as the pin 6 on which the loose bow D turns is then inside the case A, which latter, as the necks I) d fit in the hole 0, holds the loose bow D locked against the bow part bof the bolt B, and the end d of the bow D takes against the stop a inside the casing. WVhen the bolt B is shot forward, (see Figs. 3 and 6,) the padlock is unlocked, as the pin 6 will then be outside the case, and the loose bow D can turn on its joint and be opened out from the bow b of the bolt B, so as to allow of the padlock being locked onto or removed from a staple or the like, as may be required.
This padlock is selflocking, as on pushing the boltB inward the projection in on the bolt through the bolt.
acts upon the inclined endj of the tumblerj, and pressing the said tumbler sidewise (see Fig. 7) passes into the notch land locks the bolt.
In order to more effectually prevent the shackle being wrenched open by twisting the outer ends of the two parts b D sidewise, we form a projecting pip, n, on the end of one part, which, when the padlock is locked, fits into a corresponding hole, 0, in the end of the other part.
Instead of one only of the halves of the shackle being made loose from the bolt B, as above described, both halves may be made loose and similarly hinged to the bolt B, as in the modification illustrated by Figs. 12, 13, 14, 15, 16, and 17. The two halves of the shackle are respectively marked Dand D At the bottom of each of the parts D D is a pair of ears,
those on D being marked 9 p and those on D being marked g g. The end I) of the bolt B fits between these ears, and they are there jointed by a pin, 1, passing through them and As in this case the hole a does not form a guide for the bolt, an additional guide, 8, is formed inside the case, between which and the stop a the boltB can slide. The parts which we have not described in this modification are similar to corresponding parts in the padlock hereinbefore described, and illustrated by Figs. 1 to 10, both inclusive.
In the manufacture of these improved padlocks there is a considerableadvantage, as the size of the shackle can be varied without altering the size of the padlock-case and the mechanism contained thereinforinstance, as shown by Fig. 11, where the size of the shackle is considerably increased without altering the casing A.
It will be evident that the shape of the shackle can be varied without departing from the nature of our invention, as instead of being ring-shaped it may, for instance, be a hollow triangle or an oval ring, and it may be so divided that one arm or how is larger than the other.
What we claim as our invention, and desire to secure by Letters Patent, is-
1. In a padlock and in combination, a nonrotating case, a shackle formed in two parts, a sliding support for said parts, and operating means for the sliding support, substantially as described.
2. In combination, the case, the shackle formed in two parts, a sliding support, B, the pivot-point e of the two parts of the shackle being on said support and adjacent to the opening in the case, a tumbler and operating means for the support, whereby the pivot may be thrown into and out of the case, substantially as described.
In testimony whereof we have each signed in the presence of two subscribing witnesses.
