SEAL-LOCK.

SFEGIFICATION forming part of Letters Patent No. 285,384, dated September 25, 1883.

I Application filed May 9, 1893. (No $1nodel.)

To a/Z whom t may concern,.-

Be it known that I, EDWARD J. Bnooiis, a citizen of the United States, residing at East Orange, in the State of New Jersey, have in- 5 vented a new and useful Improvement in Seal- Locks, of which the following is a specification.

My present invention consists in a glass-seal padlock having its key-hole and a horizontal seal-holding recess in its bottom, with an opening at one edge to receive the seal and a vertically-moving gate actuated by the shackle of the lock to retain the seal, whereby I am enabled to insert the seal edgewise with facility, and to vfasten itin the act of locking theshackle of the padlock without eXtra motions or complication of parts, while at the same time the seal is effectively protected by its position,and the key-hole is securely covered bythe seal itself` without extraneous aid.

A sheet of drawings accompanies this speciiication as part thereof. Figure l of these drawings is a front elevation of my said selflocking glass-seal padlock and its unlockingkey. Fig. 2 is aback view of the front or main part of the lock-shell with the works` therein, illustrating by dotted lines the unlocking operation. Figs. 3, 4, and 5 represent vertical transverse sections on the lines correspondingly numbered. Fig. (i is arbottom View of the unsealed lock, and Fig. 7 is an'edge view of the key.

Like letters of reference indicate corresponding parts in the several figures.

The shell of the padlock consists of two castings, A B, which maybe of iron or brass, and three smaller castings of the same metal Aconstitute, respectively, a shackle, C, a lever-bolt, D, and a gate/7 E, which together with two spiral springs, s Ss, complete the lock. The joint between the parts A B is central and parallel to the face of the lock, and a hinge-notch, 71, and mouth m, to receive the shackle O, a main recess, r, a seal-holding recess, rr, and a keyhole, L, are formed jointly in the two parts, as seen in Figs. 2 to 5, inclusive, the latter and said seal-holding recess being located in the bottoni of the lock, as best seen in Fig. 6. The parts A B are securely united byfour rivet- Fig. 2, cast on the former, and the shackle O is strongly and safely hinged in said hinge-notch h by means of closely-embraced trunnions t, cast on the shackle, and4 a pintle, pp, cast on the part A, and terminating within a socket, q, in the part B, as seen in Fig. 3. The mouth m is surrounded by a wall, fw, embraced by a corresponding recess in the nose end of the shackle, to exclude water, and the shackle at this end terminates in a long bev- `eled nose, n, having a notch in its' front edge to receive the nose of the bolt D, which is correspondingly beveled to render the padlock self-locking.

The gate E is arranged below and in line with the shackle-mouth m, as seen in Figs. 2 and 4, and it has a central stem, guided by a projection within the part A and embraced by the spring ss above the projection. A suitable head, hh, mayl be upset or soldered on above this spring. The gate proper is adapted to extend across and tightly close the open end of the seal-holding recess rr, as seen in Figs. 2 and 4, and in dotted lines in Fig. 6, and is depressed into effective position and heldthere by the nose of the shackle bearing on said head 11.11.. Reacting against this head, said spring ss tends to re-elevate the gate and eject the shackle, and so operates when the shackle is released, as illustrated by dotted lines 1n Fig. 2, unless the shackle be locked. A downward bend in the bolt D forms a square shoulder in i line with its nose, and this is drilled to receive one end of the spring s, by which the bolt is thrown. lThe body of this spring is supported on all sides by the walls of the recess fr and supplemental projections cast on the parts A B inside, 'as seen in Fig. 5, so as to preclude displacement thereof. The bolt is pivoted near the bottom of the recess r, as best seen in Fig. 2, and has an upwardly-inclined rigid lever end, Z, to coact with a matching unlockingkey, K, Figs. l and 7. rIhe key K,being a barrel-key, is guided and supported within the key-hole k and recess r by a key-pin, fr, depending from the upper spring-supporting projection within the part A, said projection being extended and drilled to receive the pin, which is riveted fast therein. The key-bit consists of two projections, g/ z, the lower of which, when the key is inserted, insures inserting it fully, while the upper, having an inclined lower surface, (best seen in Fig. 7,) acts 'I oo upon said inclined lower end, Z, of the bolt D, and turns the latter upon its pivot to release the shackle C, as illustrated by dotted lines in Fi 2.

Vhile the padlock is unlocked the gate E remains in elevated position. An ordinary glass seal, S, Figs. 3 and 5, may now be slid lengthwise into the open seal-holding recess rr, and the shackle C be passed through a staple or pair of staples and snapped shut, when the whole will be sccurely'locked. The face ofthe seal is exposed within an opening, o, Fig. 6, of ainple size, and it can readily be inspected by turning up the lock', while as the lock hangs it is effectively concealed and protected. The open end ol' the seatholding recess being located at the rea-r en d of the lock with reference to the direction of travel, (indicated by an ar row in Fig. 1,) rain and dust beat against solid walls, and any clogging of the seal-holder is precluded; and until the shackle is securely locked its ejection by the reaction of the gatespring ss, as aforesaid, will indicate the fact and preclude leaving the padlock unlocked by oversight. Preparatory to unlocking, the seal l S is broken by a breaking-poi nt, b, on the key K, or other convenient means, and the key is inserted and given a quarter-turn. rlhis draws back the nose ot' the bolt D, as aforesaid, and allows the gate E to rise and ej cet the shackle C. I do not lilnit myself to any particular forni of spring, norto the described 'forni of bolt, but propose using springs of any preferred make, and may use, for example, a horizontal sliding. bolt, retracted through the medium of a bellcrank lever siinilar to the lower part of the le ver-bolt D.

I am aware that a seal-padlock having its key-hole in its vertical face, and a sliding keyhole cover to protect the same, has been constructed with a seal-holding recess below its main recess or lock-chan1ber within a tail-extension of the lock, the seal being inserted flatwise and retained in vertical position beneath said key-hole cover by a sliding bolt, 7 7 which is grooved to receive a portion of the seal, so as to hold the seal in the recess/7 said bolt being actuated by the shackle, and serving to elevate the latter' when unlocked. I ain also aware that another seal-padlock is constructed with a recessed bottoni furnished with a pivoted sealholder, in which the seal is held within the bottoni of the padlock, so as to be out of sight. In my glassseal padlock I dispense with any key,- hole cover other than the seal itself, and also with any holder 'for the seal other than that formed by asini ple recess in the padlock itself.

I claim as new and of niy invention and desire to secure-by Letters Patent- A glass-seal padlock having its key-hole and a horizontal seal-holding recess in its bottoni, with an opening at one edge to receive the seal, and avertically-inoving gate actuated by the shackle of the lock to retain the seal, substantially as herein specified., for the pur poses set forth.
