Matted tatet 1li/latent @titille CHARLES T. GIBSON, OF BALTIMORE, MARYLAND, ASSIGNOR TO HIMSELF AND SAMUEL E. KIRK, OF SAME PLACE.
Letters Patent No. IQ1,607, dated April 5, 1870 nfntwlalell March 29, 1.870,.
IMPROVEMENT IN PADLOCKS.
The Schedule referred to in these Letters Patent and making pari: 0f the Bama To all whom it may concern Beit known that I, CHARLES T. GrBsos, of the city and county 'of Baltimore, in the .State of Maryland, have invented a new and improved Padlock; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part 'of this specication, in which- Figure lis a view of the interior of the lock, as seen by removing its face-plate, showing the link or shackle locked in its place.
ing deviceto the bolt of a padlock which will positively lock the bolt forward, and which will admit of being made so strong that itcannot be broken vor displaced by violent blows upon the lock-case, but
can be easily moved out of the way by the -key adapted for moving said bolt, as will be hereinafter explained.
To enable others skilled in the art to understand my invention, I will describe its construction and operation.
In the accompanying drawing- A represents the case or frame of the and B, the link or shackle, which may be constructed in the usual well-known manner.
The shackle is pivoted at a between the external ears of the lock-case, and it is constructed with a slotted entering portion, b, for receiving .a sliding bolt, E, and the hooked end of a pivoted dog, O, as shown in iig. 1.
The hooked locking-dog C is pivoted to the fixed stud c', and constructed with a tail extension, c, which curves over the key-stud ll, so as to be acted upon by the bit of the key K, and lifted, as shown in fig. 2, in which latter position the hooked end of this dog will release the free end of the shackle.
The bolt E, which has a beveled nose, that will cause it to spring back when the nose br of the shackle is pressed upon it, is acted lupon from behind by a'spring, Z, that is coiled around the xed stud l', which spring will force this bolt forward and hold its shouldered portion against the attened stud m, which isjust below the upper or entering portion oi padlock the holt, as shown in the two figures in thev annexed drawings. I
The studs m m and the top portion of the case A guide and keep the bolt E in place, but allow it to be readily moved endwise away from the nose, of the shackle by the use ofthe key K.
On the rear portion ofthe bolt E a boss, c, is4 formed, which will engage with the free notched end of the pawl or locking-piece g, when this bolt is allowed to spring forward, as shown in iig. 1.
The pawl g is pivoted to a fixed stud, h, and acted upon by a spring, i, which spring acts upon the upper end of the lock-caseA, and forces the `free end of the pawl down to its place in rear of the boss e, and holds it there, as shown in iig.'1..
The pawl g is constructed with a tailfpiece, g', which is held on the curved tail-piece c of the hooked dog O by the spring i, thereby allowing this spring i to operate, through the medium of the pawl, upon the said dog, to keep its hooked end in place for receiving the nose b of the shackle B and assisting in locking this shackle.
The guard-strip k', which is fastened by means of studs c and h over the parts C g, keeps these parts in place for operation.
The spring j, which is fastened to the stud h, at one end operates against the nose b of the shackle B, to throw it open when released from the bolt and the dog-hook.
It will be seen from the above description that I employ but -three movable pieces, excepting the springs, to effect the locking of the shackle and the l locking of the belt; and when the shackle is locked, by simply pressing its nose against the dog-hook and bolt until they engage with it, the pawl g will by its spring i be moved behind the boss e on the boltv and'tliere remain until lifted out of the way by the application to the lock of the proper key.
When the key k is inserted into the lock and turned, it will press upward the tail c of the dog, and disengage the hooked end of this dog from the shackle; at the same time the pawl g will be raised free from the boss e.
The next movementl of thexkey will then move back the b'olt E and release the shackle, which latter will be thrown open by the spring j.
When the key is removed, the dog, the pawl, and the bolt-- will he forced to the positions shown in fig. 1.
It is obvious that the bolt E cannot be forced back when locked by the pawl g, by the application of blows upon the lock-case.
I do not claim, broadly, the idea of locking a spring padlock-bolt, as others have done this before me, but such locks have been found to be too weak, on account of the great number of parts required in their cases, to answer the purpose for which they are ehiey required, and being so complex, such locks frequently become deranged and broken. Having described my invention,
What I claim as new, and desire to secure by Letters Patent, is-
The tail-extension c, formed on the hooked locking-dog C, arranged beneath a pawl, g, lwhich is adapted for loeking'the bolt; E in a forward posit-ion, substantially as described.
