PADLocic SPECIFICATION foi-ming para of Letters Pate/ni: No. 367,829, ated August 9, las?.
Application Bled May 10` 1887. Serial No. 237.706. (Model.)
To all whom it may concern:
Be it known that I, OTTO J. MEINHARD, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Padlocks, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention has for its object to provide a padlock arranged with various safety devices that, without being known to a person, will prevent him from opening the lock even when in possession of the key; and these improvements mainly consist, first, of a swinging key-hole guard locked over the key-hole by the pin of a spring arranged inside of the lock-casing, which spring must be depressed from the outside by pressure on an imitation rivet-head extended through thecasing and being iiush therewith 5 secondly, of a rotary fulcrum-pin'and barrel-socket to receive the barrel of the key, which'fulcrum-pin and barrel-socket, being rigid with eachother, can be turned to prevent the insertion of the key until adjusted to proper position, and, thirdly, in
` a sliding plate under a strip at the rear of the lock-casing, having a ln g that will prevent the insertion of the bit of the key to a depth sui-lieient for entering the casing until such lug has been removed by pulling the slide-plate to which it is attached, all as will be more fully hereinafter described and specifically claimed.
In the accompanying dra wings, Fignrel represents an elevation of the padlock as closed;
. Fig. 2 a front elevation, and Fig. 3 a sectional bott'om'view, of the lock with the bow of the key applied for releasing and turning the keylhole guard; Fig. 4, a front elevation of the lock, showing the key-hole guard swung side.- wise and the barrel-socket turned to a position preventing the insertion of the key. Fig. 5 is a front elevation of the key-hole part of the lock with key applied for adjusting barrelsocket. Fig. 6 is a similar view with key in position after adjustment of barrel-socket. Fig. 7 is avert-icalcross-section of the lock with the key inserted to the extent the lug of the movable slidingjplate will permit. Fig. Sis a vertical cross-section of the lock with the lug moved to clear the web of the key and with the key fully inserted for opening the lock;
and Fig. 9 is an elevation of the lock, the keyhole plate of the casing being removed.
Corresponding letters in the several figures of the drawings designate like parts.
A denotes the casing and B the hasp of the padlock,.which latter is pivotally secured in the casing with one end, while its opposite flattened end,that enters thelock-casing, is provided with the bolt-engaging hole in the usual manner. The boltClnoves on aV-guide, forming part of the rear face-plate of the casing,
and has aprojecting stump, 11,'that projects into a slot otla swinging tumbler, D, engaging with either one of two notches, c, in the ends of such slot. This tumbler D is depressed by a leaf-spring, d, secured against its upper edge.
Between the eye of the key-hole e and an eye in the rear face-plate ofthe lock-casing is pivotally secured a tubular socket, E, slitted for clearing the bit on of key M, and having secured a rigid axial stud, f, sectionally crossshaped and entering the similarly shaped tubular opening in the barrel n bf key M. This socket E, after locking the bolt, is to be turned with its slitaway from the slot of the key-hole, as shown by Fig. 4, thereby misleading a person trying to openbr pick the lock, while for a person acquainted with the device it is an easy matter to turn the socket E to the proper position by applying the end of the key to engage stud fand then turning such key, as shown by Figs. 5 and 6 ofthe drawings.
The key-hole guard or curtain G, swinging on a screw pin or rivet, g, from the upper edge of the front face-plate of the lock, has a socket in its lower end engaging with a pin, h, that projects through a hole, t', in the casing and is rigid with one end of a leaf-spring, H, the opposite end of which is secured against the inside of the front face-plate of the lock-casing. This spring has also secured thereon a stud, j, projecting into a corresponding hole in the face-plate and made in appearance to be one of four rivets that hold the lock-casing together. Each of these rivets, as well as stud f j, are center-punched, and the bow o of key MV has a projecting central point, p, that, being inserted into the center-punch socket of stud j, when pressed upon, will disengage the pin h from the socket in guardr G, and then with turning the key-bow o it will push the guard IOO G away from the key-hole e. After the keyhole e has been thus exposed and the socket E has been turned to admit the web in of the key M, still sueh key cannot be inserted to the full extent for the web m to enter so as to be rotated for engaging the bolt and tumbler, by reason of the presence of a lug, 7, projecting from under the rear face of the easing A into the same, forming a stop for the key-web. This lug l forms part of a plate, J, vertically sliding in a groove under a strip, k, that is secured against the rear vface of the leek-easing and resembling the key-hole guard G. The lower end of this strip is detached and forms the head or handle p' of plate J, that is-moved thereby, the dividing-line between strip 7n and handle p being a crease to insert the fingernail for grasping plate J. The rear faceplate of the loekeasing being slotted Similar to the key hole, the lug j is permitted to move therein, and the pulling` downward of plate J will move lug Zto a position that will clear the web m of key M, when such key can be inserted and rotated in the lock-easing for re-drawing the bolt and opening the hasp.
It will be readily seen that a lock thus eonstructed with these various safety appliances cannot be readily opened by a person not acquainted with the several devices.
1. In a padlock, the socket-piece E and stud f, adapted to engage the key-barrel, both integral and pivotal in the lock-easing, substantially as and for the purpose set forth.
2. In a padlock, the combination of the plate J, having stud Z and head p', with the strip k, between which and the rear face of the lockeasing said plate is adapted to slide, substantially as set forth.
Arpadloek consisting of ease A., bow B, swinging guard G, spring H, provided with pin 7L and study', for securing said guard over the key-hole, pivoted socket-piece E,with pin f, adapted to receive the key-barrel, and slideplate J, with stud Z and head p', and strip 7.7, between which and the back easing of the leek the said plate J is adapted to slide, all substantially as and for the purpose set forth.
In testimony whereof I affix my signature in presence ol' two witnesses.
OTTO J. MEINHARD.
