SEAL-PADLOCK.

SPECIFICATION forming part of Letters Patent No: 549,951, dated November 19, 1895.

Application filed June 17, 1895. Serial No. 553,022. (No model.)

T a/ZZ whom/ zit may concern,.-

Be it known that I, THOPHILE BLANGER, a citizen of Canada, residing at Montreal, in the district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Padlocks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part hereof.

The object of my invention is a padlock specially designed for car-doors, mail-bags, and the like, and one that cannot be opened without punching a card or ticket which has been inserted prior to the padlock being locked. This card is fastened in the lock and cannot be withdrawn until the key is turned.

In the drawings, Figure 1 is a perspective view of my lock. Fig. 2 is a front view, the cover being removed, showing it locked, the dotted lines showing it unlocked and the position of the key when the cardV or ticket is being pushed out. Fig. 3 is a section on line 3 3, Fig. 2. Fig. 4 is a section on line 4 4, Figs. l and 2, showing the card inserted and locked. Fig. 5 is a similar section unlocked and the card partly withdrawn. Fig. 6 is a section showing the interior of the lock from the back, the key-bit being shown engaging the bolt of the lock and also in dotted lines engaging the device for pushing out the card or ticket. Figs. 7, 8, and 9 are details of the lock. Figs. 10 and ll are an end view and section of the key.

The lock-casing, which I prefer to make rectangular in shape, consists of the back A, side walls and 2l, top wall 22, bottom 23, and cover B. The back, side, top, and bottom walls may be cast integrally. Lugs 24 and 25 are formed at each side of the top on the back and cover, and in the lugs 25 the curved jaw C is pivoted. The free end of the jaw is slotted at c for the locking-bolt to pass through. An aperture 26 is made in the top wall 22 for the passage of the end of the jaw. Studs 27 and screw 28 are provided for holding the cover in place. A key-post D is secured in the back and projects into the keyhole in the cover. This post is cut away at CZ for the passage of a card or ticket to be hereinafter mentioned.

The cover B is provided with apertures fitting the studs 27 and screw 28, a keyhole 29, and a slot h, through which any number or legend on the card or ticket may be read. A guard or keeper E is pivoted to the cover, so as to cover the keyhole 29 and slot h.

F is the lock-bolt adapted to be shot by the spiral spring f. A slot 30 is provided in the center of the bolt and the bolt slides on a flattened stud 31, the said stud passing through the said slot 30. The front end 32 of the bolt is thinner than the rest and is adapted to enter the slot c in the end of the jaw C, the upper portion of the end 32 being rounded 01T, so that the bolt will be pushed in against the spring fwhen the jaw is pressed down. A tongue 33, turned back and depending from the bolt F, is formed integrally therewith and adapted to be engaged by a key-bit lc of the key K, and'thus retract the bolt and disengage it from the slot c in the jaw C.

Thus far I have described a simple and efficient padlock, and below isa description of a device which prevents the lock from being tampered with.

A slot 34 is formed in the side wall 20 of the case. This slot is just wide enough to admit a card or ticket T. This ticket or card T is pushed in through the said slot 34 and rests upon a plate 35 in the lower portion of the casing, the said plate 35 being just far enough from the cover B to admit the card or ticket snugly. The cut-away portion d of the keypost D forms a guide for one side of the card, a raised portion 36 on the plate 35 forms a guide for the other side, and a sliding bar 37 forms a stop for the end of the card.

The plate 35 is cut away at 38 to miss the key-post D and allow the key K to be inserted. Two longitudinal slots 39 are formed near the end of the plate 35 to allow rivets 40 to secure the sliding bar 37 to aplate 4l,this plate being pressed away from the side wall 20 by a spring 42'7 and is provided with a notch 43, adapted to be engaged by the key-bit lo, as shown in Fig. 6. A guide for the mechanism for closing the slot 34 is formed by depending wall 44, formed integrally with the plate 35 and the side wall 20 of the casing. This depending wall reaches to the back A and forms a support for the plate 35 and also an abutment for the spring 42.

The slot 34, through which the card or IOO down the bolt 5l.

ticket is inserted, is closed by the following device, viz: A sliding plate 45, the full length of the slot 34 and sliding against the wall 2O of the casing and between it and the depend ing wall 44, is heldin position by a pin 46, secured in the said side wall 20 and passing through a slightly elongated slot 47 in the said plate. A recess 48 is formed in the cover B to receive the edge of the plate when the slot 34is closed. The under side of this plate, which is thicker than the upper portion, is provided with a series of inclined faces 49, adapted to be engaged by a series of similar inclined faces 50 of a bolt 51, sliding under the said plate or between it and the back A of the casing. A spring 52 presses this bolt toward the top of the casing. A stop 52 is provided abutting against one of the studs 27. The bolt is then bent away from the side wall 20, so that the upper end comes in contact with the nose of the curved jaw C.

The key I( has one-half of the barrel formed with a knife-edge 54, adapted to eut olli' that portion of the card or ticket T resting on the portion d of thekey-post l). A slot 55 is made at the upper end of the barrel for the extraction of the bits of cardboard thus cut off.

An eye G is formed on the lower end ofthe lock-case, by means of which the lock maybe secured to the door or bag to prevent its be ing lost when not in use.

The operation of the device is as follows: A card or ticket is inserted in the slot 34 and numbers or legend or word written or printed so as to appear at the slot 7L in the cover. The back is then placed in position and jaw C pressed down. The nose of the jaw presses The inclined faces on this bolt, engaging the inclined faces on the plate 45, press the plate up so as to cover the slot 34. At the same time this is being done the nose of the ,jaw presses back the bolt F until end 32 is opposite the slot c, when the spring-slot, the bolt, and the jaw are locked. In unlocking the lock it will be seen that a key cannot be inserted without mutilating the card or ticket T, thus enabling any one to see at a glance if the lock has been tampered with. The right key K on being inserted cuts off a selnicircular piece from the card, and then, on being turned in the direction of the arrow, engages the tongue on the bolt F and retracts it. The bolt 51 is then pressed up by the spring 52, and so allows the plate 45 to drop, opening the slot 34. The key is then turned until the position shown by dotted lines in Fig. 6 is reached, when it engages the notch 43, and, continuing, draws the sliding bar 37 toward the slot 34, and so pushes the edge of the card or ticket T through the said slot 34 and enables it to be withdrawn. The back is hermetically sealed when locked, the guard or keeper closing the keyhole and slot h, the end of the jaw C, the slot in the top wall oi' the casing, the sliding plate, and the s101534, so that it is impossible for water or dust to enter.

Having now fully described my invention, what I claim isl. In a pad-lock, the combination with the casin g having a slot for the insertion of a card or ticket oi' a sliding plate adapted to close the said opening, a series of inclined :li'aces on the under side of the said plate, a bolt having a series of inclined faces adapted to engage the said inclined faces on the sliding plate, the said bolt by being pushed one way will cause the sliding plate to close the opening and the other way will open Ait substantially as set forth.

2. In a paddock, the combination with a sliding plate adapted to close a slot in the side of the casing, inclined faces on the under side of the said plate, a bolt having a series of inclined faces adapted to engage thc inclined faces on the said. plate, a spring pressing the said bolt in one direction, and the jaw of the lock, the nose of which is adapted when the lock is being closed, to press the said bolt against the said spring su bstaniiall y as set forth.

3. In a pad-lock, the combination with the casing having a slot in the side for the inscrtion of a card or ticket and means for opening orclosing the said slot, of a plate on which the ticket is pushed, a sliding bar sliding on the said plate, the said bar being connected by rivets passing through slots in the said plate to a sliding plate on the other side thereof a spring adapted to push the said sliding plate away from the said. slot, the said sliding plate having a notch adapted to be engaged by the bit of the key, substantially as set forth.

4. In a pad-lock the combination with the key post D having a cut away portion d, on which the edge of a ticket or card rests, of the key K having a knife edge 54 formed on the barrel adapted to cut oii that portion of the ticket or card resting on the said cutaway portion (l and a slot 55 through which the portion of the ticket cut off may be extracted from the barrel of the key, substantially as set forth.

Signed at Montreal this 28th day of May, 1895.
