Letters Patent No. 104,038, dated June 7, 1870.

IMPROVEMENT IN. SEAL-LOCKS.

To all whom it may concern.-

Be it known that we, Gnomes L. Krrsos, J osnua F. LANING, and JOSEPH Benson, of Philadelphia, in

the county of Philadelphia and State Pennsylvania, have invented certain "Improvements in Padlocks, of which the following is a specification, reference being bad to the accompanying drawin g.

Our inventionconsists in constructing a seal-lock with 'a catch projecting from the side of the lockingdog through a hole in the side of the case to engage with a catch on the seaheover, and in arranging the locking-dog in such relation to the hasp and the sealcover that either may be shut and fastened by the locking-dog without releasing the other, as'hereiuafter more fully described.

Figure l is a side view of the lock, with one side of the case removedso as to showthe interior arrangement;

Figure 2,'a side view of the lock complete, with hasp and seal-cover open;

Figure 3, a cross-section of the lock, on the line a a: of fig. 1.

Figure 4, an inside face-view of the seal-cover detached; and

Figure 5, a perspective View of the locking-dog detached.

In constructing our lock we first provide two metal plates, A and A, of any suitable shape and size, and so formed that, when'fitted properly together, they shall form a suitable case to receive the hasp andcontain the locking'devices Through the front plate A we cut a key-hole, I), to admit the key D, which is made with a solid stem, a, projecting beyond the bit, and through the back plate A we make a hole, 0, to receive the end of the stem or barrel of the key when the same is inserted from the front, as shown in fig. 3.

We next construct the hasp Bwith a hook at its front end, and two laterally-projecting bosses or studs d on opposite sides of the back end.

The edges ofthe plates A and A we cut away, so as to admit the hasp between them, and in the inner faces of the plates we form recesses to receive the studs (1, 'upon which the hasp turns as on a pivot, the hasp and the studs, of course, being inserted before the plates are put together.

We next provide the seal-cover 0, having an arm, 1', with'studs j, and into the edges of the plates A A we cut a recess, 7a,.and in the adjoining faces form notches l, and, before fastening the plates together, insert the arm of thecover into the recess 7;, and its studs j into the notches l, as shown in fig. 1, so that,

when the plates are fastened together, the cover is soeured to them, but left free to swing or turn on the studs.

In the back side of the plate A we form a depression or recess, into which the seal-cover may fit closel y and be flush with the plate, as in fig. 3, and on the. inner side of the said cover we fornr a hook or catch, 72, which, when the cover is closed, projects through a hole, 411, to the interior of the case, and we also provide the cover with a central hole, r which the stern of the key enters when inserted.

On the inncrfacc of the plate A we form two studs, 0 and f, and 011 the former of these mount a lockingdog, 1*), having an arm, n, anda catch or hook 0, on one side, as: shown in 1 and 5. This dog is so located that its front end will engage with the hook on the end of the hasp when the same is shoved inward, and that its hook 0 will project into the hole in and engage with the catch hof the seal-cover when it is closed, as shown in figs. 1 and 2, the one dog thus serving to lock both the hasp and seal-cover at the same time.

Within the case I arrange a spring, G, held in place by the stud f, which is slotted to receive it, the front end of this spring engaging with the. front end of the dog, and holding it down, and the rear end bearing behind an arm at the rear end of the hasp, so as to throw the hasp open when released.

Between the two' plates, in line with the upper portion of the key-hole, we mount a rotating sleeve or hub, 1, having a slot cut down one side, so as to allow the'bit ot' the key to enter when the sleeve is properly adjusted. The object of this sleeve is to protect t-helocking devices from being operated upon by tools inserted through the key-hole, and to aid in guiding and supporting the key proper-when insert-ed.

To aid in adjusting the hub so as to permit the entrance 'of the key, we form, on its interior, a longitudinal groove, n, and on the barrel of the key, near its end, form a corresponding stud, so that, by inserting the end of the key, with the stud, in the groove, and. then tnrningthe bitarouud tothe key-hole,'the key can be shoved into it's, place.

The two plates A and A we fasten together by passing screws t through the plate A, into, but not through the plate A, as shown in fig. 3, the screws being so located that they are all hidden by the sealcoverrwhen closed, as shown in figs. 2 and 3, so that they cannot be tampered with from the outside.

It is obvious that, instead of screws t, studs properly located may be formed on the plate A, passed through holes iufthc plate A, and riveted down, thus answeringall the purposes, and being concealed in the same manner as the screws.

In fastening our lock the hasp is merely shut, as in the ordinary spring-locks, when the dog will engage with the hooked end of the hasp and securely hold it, as shown in fig. 1. v

The seal, which may be made of any suitable material, as paper, tin-foil, or wax, is then laid over the hole in the back,'and the cover 0 shut down on it,

when it also will be secured by the dog, as shown'in v fig. 3, and thus the seal locked in place, so that it cannot be removed except by operating the dog E and releasing the cover 0.

When thus arranged, if a key be inserted to open the lock, it will puncture or deface the seal, and thus show that the lock has been tampered with.

The key, being inserted and turned, strikes the arm n of the dog, and, tipping it, releases the hasp and the seal-cover simultaneously. The hasp, when released, is immediately thrown up by the spring.

In order to prevent the possibility of inserting any kind of a key or tool without defacing the seal, the seal-cover C may be placed on the front side of the lock, with a key=hole formed in it, so that it will be impossible to insert even a wire into the look through the key-hole without puncturing the seal.

It will be observed that by this method of constructing the look a single swinging dog serves to lock both the hasp and seal-cover, and that either may be locked first, and the other then shut and locked without releasing the one first locked, the key at the same time unlocking both Simultaneous] y.

Having thus described my inventor], What I claim is w 1. The swinging locking-dog E, having the catch 0 projecting from its side, and arranged to protrudev through an. opening in the ease and engage with the catch h of the seal-cover, substantially as described.-

2. The locking-dog E, arranged, in relation to the hasp and the seal-cover, so that either the hasp or the cover may be shut and locked automatically by the single dog or bolt E without unlocking the one previously shut, substantially as described.
