WITNESSES ATTORNEYS Warren CHARLES D. SMITH AND ROBERT H. THOMPSON, OF HARTSELLS, ALABAMA.
PADLOCK.
SPECIFICATION howling part of Letters Patent No. 371,796, dated October 18, 1887.
Serial No. 218,807. (ModcLl T0 aZZ whom it may concern.-
Be it known that we, CHARLES D. SMITH and ROBERT H. THOMPSON, of Hartsells, in the county of Morgan and State of Alabama, have invented a new and Improved Padlock, of which the following is a full, clear, and exact description.
My invention relates to padlocks, and has for its object to provide a simple, strong, durable, and comparatively inexpensive combination-padlock which cannot be unlocked or opened by persons unacquainted with its interior mechanisms and the manner of operating themin proper order.
The invention consists in certain novel features ofconstruetion and combinations of parts of the look, all as hereinafter fully described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a front view of a padlock embodying my improvements, with the front plate removed and with different positions of the parts indicated in dotted lines. Fig. 2 is a cross-sectional view taken on the line 00 a, Fig. 1. Fig. 3 i'sa view of the back or reverse side of the padlock, with parts indicated in dotted lines; and Figs. 4 and 5 are detail views of the ends of the lock, key, and hasp, respectively.
The back plate, A, of the lock shown has fixed to it aliange, a, to which the front plate, B, is held, and between lugs of the plates A B the hasp O is pivoted on a pin, 0', so as to swing at its reduced end 0 through a hole or slot, a, in the flange a of the lock.
The bolt D of the lockis fitted to slide in guide-studs d (I, fixed to the lock-case, and is shaped at the lower edge to be operated by a.
keybit, and in its upper edge has the usual notches, d (1, into which the stud e on the tumbler E may enter after the latter is lifted by the key. The tumbler is pivoted at e to the lock-case, and is acted on by one or two springs, c c, to hold its stud into either notch hole in the tumbler E, and may be screwed into the tumbler to prevent opening of the lock, or may be unscrewed to stand clear of the tumbler to allow it to be lifted and allow the bolt to be thrown.
The end cl of the bolt D is adapted to enter ahole, 0 made in the end 0 of the hasp O,and the other end,d,of the boltis adapted to enter a hole, 9, in the upper or outer end of a metal bar G, fitted for endwise movement in the lock-case, and to which is fixed a pin, 71.,which passes through a slot, 1), of the back plate, A, and has fixed to it, outside of said plate, a head or button, H. A spring, I, fixed at one end to a stud, i, in the lock-case, acts normally by its other end against the end of the bar G to force said bar toward the top or hasp end of the lock to carry the hole 9 thereof above the end d" of the bolt D, and thus prevents Withdrawal of the bolt by the key until the bar G is drawn or slid backward by pressure on the button H to bring the hole 9 opposite the end of the bolt. v
The key J (shown only in part in Fig. 4 and in dotted lines in Fig. l) is to be entered into a hole, K, in the front plate, B, after an escutcheon or cover plate, L, has been turned on its pivot Z from over the key-hole, and the key engages a guide-pin, M, and is fitted to turn past a ward, N, said pin and ward being fixed to'the back plate, A, of the lockcase. The notchj in the key-bit,which allows the key to turn past the ward N, also serves as a wrench socket, allowing the use of the key to set the parts of the lock to open it or prevent opening of it, as presently explained.
A dog or pawl, O, pivoted by a bolt, P, to the back plate, A, may be turned ,by engaging the head 1) of the bolt by the key-socketj, so as to swing the dog either up to the position shown in full lines in Fig. l, where it will be held by the engagement of the end of a spring, It, fixed to the lock-case, with a hole, 0, in the dog; or the dog may be swung down to the position shown in dotted linesin Fig. 1, by turn ing the bolt P by the key, the spring B being shaped at its end 1' to allow it to engage the dog and permit escape of the dog from it auto matically. A pin, S, fixed to the back plate, A, forms a stop to the dog 0, and has fixed to it a metal plate, 5, which overlaps the end of the upturned dog, and also the edge of the spring I, thus serving as a retainer to both the dog and the spring.
Another dog, T, is held to a bolt or pin, U, pivoted in the back plate, A, and having a head, it, outside the 1ock-case,and to which the key-socket j is adapted. This dog T is provided with a lug, t, adapted to enter a hole, 0 in the end a of the hasp O, and in which hole said lug t is normally held, when the hasp is locked, by means of a spring,V, which is fastened at one end to the lock-case and bears by its other end, 12, on the lower end or tail of the dog. The stud 13, to which the spring I is fixed,ser.ves as a stop to prevent the spring V throwing the dog T too far in one direction, and a pin or lug, t, fixed to the back plate, A, prevents turning of the dog in the other direction any farther than is necessary to withdraw the lug t thereof from the hasp.
When the padlock is fully locked, its parts will have the relative positions shown in full lines in Fig. l of the drawings. The screw F will then prevent operation of the tumbler and bolt E D, the dog 0 will prevent turning of the key to the bolt, the bar G will prevent withdrawal of the bolt D from the hasp, and the dog T will prevent withdrawal of the end 0 of the hasp from the body of the lock.
To unlock the padlock, the screw F must be unscrewed from the tumbler E, and the dog 0 must be swung over backward to the position shown in dottedlines in Fig. 1, which may be done by applying the key-wrench socket j over the heads of the bolts F P, respectively. The key J may now be passed into the key-holeK and turned past the lowered dog 0 to the tumbler E, and when the bar G is slid backward by pressing back the button H by the hand the bolt may be thrown back by the key, so its end d enters the hole 9 of said bar. The dog T must now be turned, by applying the key as a wrench to the bolt or pin U, to the position shown in dotted lines in Fig. l, which will withdraw the lug if from the hasp O, to allow the latter to be swung open.
It is obvious that the padlock cannot be opened by any one not knowing its interior construction and how to operate the bolts or pins F P U and the button H at the outside of the lock, as above described; hence the lock is a very safe one, not likely to be picked by thieving persons. Furthermore, the lock is very strong and may be made cheaply, and
adapted, and a spring, I, normally forcing the bolt to carry its hole 9 out of line with the end of the bolt, said bar having a pin, h, passed through a slot in the lock-case and adapted to operate said bar, substantially as described, for the purposes set forth.
2. In a padlock, the combination, with the lock-case, of a dog, 0, pivoted thereto and adapted to be thrown across the path of the key, and said dog provided with a bolt, P, passing through the lock-case, a spring, R, adapted to hold the dog, and the stop S, limiting the movement of the dog, substantially as de-' scribed, for the purposes set forth.
3. In a padlock, the combination, with the lock-case and a hasp, 0, provided with a hole, a", and a spring-pressed dog, T, havingabolt, U, passing through the lock-case, and a lug, t, adapted to enter said hole 0, of stops z t in the lock-case, substantially as' shown and described.
4. A padlock constructed substantially as herein shown and described, and comprising a case, a pivoted hasp, O, a bolt, D, and tumbler E, a bolt or pin, F, fitted to the case and adapted to a hole in the tumbler, a movable spring-pressed bar, G, having a hole, 9, and a pin, h, passing through the lockcase, a dog, 0, pivoted in the lock-case and adapted to be thrown across the path of the entered key, and having a bolt, 1?, passing through the lock-case, a spring, R, and stop S for said dog 0, and a spring-pressed dog, T, having a bolt, U, passing through the lock-case, and also having a lug, t, adapted to enter a hole, 0 in the hasp G, and a stop, 2', for the dog T, all arranged for operation, as and for the purposes set forth.
