Specification of Letters Patent.
Patented July 11, 1916.
Application filedMay 7, 1913. Serial No. 766,144.
To all whom it may concern:
Be it known that we, ARTHUR G. JAoKsoN and FRANK SOLEY, citizens of the United States, residing in Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain Improvements in Padlocks, of which the following is a specification.
One object of our invention is to provide a padlock which will be practically indestructible.
Another object of the invention is to provide a casing of cast metal, which isindependent of the casing containing the operating mechanism of the lock and which is used as an inclosure for said locking mechanism.
A further object of the invention is to construct a padlock so that the mechanism can be assembled in the inner casing and the shackle pivoted thereto. in order that the works can be tested before being placed in the outer casing.
A still further object of the invention is to design the look so that through-bolts or rivets are dispensed with in order that the fastening means cannot be driven out of position when once the lock is assembled and completed. r
The invention is particularly adapted for use in places where the lock is likely to be tampered with by unauthorized persons attempting to open it without a key.
In the accompanying drawings: Figure 1 is a perspective View of our improved padlock; Fig. 2 is a sectional view of the lock; Fig. 8 is a transverse sectional view on the line a-a, Fig. 2; Fig. 4 is a sectional plan view on the line bb, Fig.2; Fig. 5 is a sectional view on the line 0 c, Fig. 2; Fig. 6 is a detached perspective view of the outer casing; Fig. 7 is a detached perspective view of the bottom plate; Fig. 8 is a detached perspective view of the inner frame carrying the mechanism; Fig. 9 is a perspective view of the key hub; Fig. 10 is a sectional perspective view of the key hub looking in the opposite direction from Fig. 9; F 1g. 11 1s a perspective view of the plates for holding the key hub in position; Fig. 12 1s a sectional perspective view of the key hub and part of the casing; Fig. 13 1s a view of a modification showing the separate-plate at the top of .the casing; Fig. 14 is a view illustrating the plate at one side of the casing; and Fig. 15 is a perspective view showing the inner frame attached to the plate.
Referring to the drawings, 1 is the casing of the lock made of cast metal, preferably of brass or bronze, and made in one piece having an opening 2 for the key hub and openings 3 and 4 for the shackle 5.
6 is the pivot pin for the shackle which passes through an opening 7, Fig. 6, in front of the casing 1. This opening extends through the front of the casing but does not extend through the back of the casing. A flange surrounds the opening in the casing, as shown in Fig. 6, and this metal is forced over the pin, as in Fig. 5, and hides it from view and also prevents the pin from being removed after it is once inplace. ,The heel of the shackle has an extension 8 and the nose 9 of the' shackle is notched in the ordinary manner so that, in this type of lock, the nose and the heel of the shackle are engagedby the bolt 10, Fig. 8, which may be of the ordinary form. i
The casing 1 is open at the bottom and mounted in the opening is a bottom plate 11 having flanges 12, which extend backto the ends of the casing 1. In the bottom plate are holes 13, which extend part way into the plate from each side, as in Fig. 5, and which aline with the holes 14 in the front and rear walls of the casing 1 forthe reception of pins which are driven in the holes and secure the bottom plate in the casing. When the casing is burnished the pins are completely hidden from view; it being impossible to remove them without destroying the lock. The bottom plate snugly fits the casing so that when the casing is burnished the parting line disappears and the casing has the appearance of a solid casting.
15 is the inner frame which is made of plates 16' and 17 spaced apart by posts. 18, some of which form the pivots for the looking mechanism. The bolt 10 is mounted within the casing as are also the tumblers 19 and the other mechanism of the lock. In the plates 16 and 17 are the openings for the shackle pivot pin and the openings for the key hub. V
It will be understood that while we have shown a certain type of mechanism in the drawings confined within the frame 15, the
mechanism may be varied according to the type of lock desired. \Ve lay no claim in this application to the mechanism contained within the casing.
The front plate 16 of the frame is recessed and has an opening 20 for the key hub 21 and is countersunk, as at 22, around the opening for the reception of the thin plate 28, which is forked and fits between the two walls of the countersink 22 and extends into the groove 24 back of the face plate 25 of the key hub 21. The key hub extends through the opening 2 in the front of the casing 1 and through the opening 20 in the front plate 16 of the inner frame and has its bearings in an opening in the rear frame 17 and partly in the casing, as illustrated in Fig. 4. After the key hub is in place, the plate 23 is slipped into position and holds the key hub against longitudinal movement, but allows it to turn freely with the key. The plate 23 may be made in a single piece, as shown, or it may be made in two pieces without departing from our invention.
In assembling the lock, the frame 15 is placed in the casing 1 and when the holes for the pivot pins are in line with the holes 7 of the casing, the shackle 5 is placed in position and the pin 6 is driven which attaches the inner frame to the casing and the shackle to both the frame and the casing. The key hub is then put in position alining the inner frame with the casing and the plate 23 is driven into the countersunk space 22 between the plates 16 of the frame and the outer line of the casing. The lock can now be tested to insure its working properly after which the bottom plate 11 can be placed in position and the pins driven into the holes 13 and 14 after which the flange around the opening 7 is turned down over the pivot pin and the lock is burnished so as to render the pins invisible, also the joints between the casing and the bottom plate, thus making a lock which is practi-,
cally indestructible. The key hub 21 is held by elements within the casing and the shackle and the bottom plate are held by pins which cannot be driven and which are hidden from view by the burnishing.
The casing is preferably made of brass-or bronze, which is tough and which cannot be easily broken. In some cases, as an additional precaution, the bottom plate may be brazed to the casing and the pins dispensed with, but we prefer the construction shown.
As the mechanism is assembled complete in the inner frame the shackle can be temporarily pivoted thereto and the mechanism tested before the frame is placed permanently in the outer casing and when the pivot pin for the shackle is finally placed in position it properly locates the inner casing in respect to the outer casing and when the transverse key plug is in position then the parts are brought into absolute alinement without the use of the ordinary rivets and posts.
In Fig. 13 we have illustrated a modification in which the lock casing 1 is open at the upper end instead of at the lower end and the end plate 11 is arranged to be located in the opening and notched to allow for the movement of the shackle, the plate being secured in the same manner as the plate illustrated in Fig. 2.
In Fig. 14, we have illustrated a casing 1 having an opening at one side instead of at the end and the plate 11 is shaped to fit the opening.
In Fig. 15, we have illustrated another modification in which the plate 11 is rigidly attached to the frame 15 carrying the mechanism of the look so that when the plate is removed from the casing 1, the mechanism is removed with it. The plate can be held in place by rivets or the edges of the plate can be beveled, as illustrated in Fig. 1, and the casing hammered down over the plate and after being burnished the joint is obscured from view.
We claim:
1. The combination in a padlock, of a casing made in a single piece open at one edge and having an opening in the front wall; two openings for the shackle; a plate arranged to close the opening of the casing; locking mechanism contained in the casing; a shackle pivotally mounted in the casing and arranged to be engaged by the locking mechanism; a key hub extending into the casing and through the locking mechanism; and a plate for locking the key hub to the casing.
2. The combination in a padlock, of a casing; a bottom plate fitting the opening in the casing, the casing being countersunk; a frame carrying the locking mechanism mounted in the casing; a key hub extending through the front wall of the casing and into the frame, said key hub having a groove therein, the frame being countersunk; and a plate mounted in the countersunk portion of the frame and extending into the groove in the key hub, the bottom plate holding the last mentioned plate in position.
3. The combination in a padlock, of a hollow casing made in a single piece and open at one edge only; a plate fitting said opening; means for securing the plate to the casing; a frame carrying the locking mechanism; a shackle; a pivot for the shackle of less length than the width of said casing, said pivot extending short of either side of the casing, the metal of one side being forced over to cover the pivot pin so as to prevent the removal of the pin after it is once in place. I
4:. The combination in a padlock, of a cast metal casing made in a single piece and having an opening in the bottom; a key hub opening in the front plate and two openings in the top for the shackle; a shackle pivoted to the casing; a pivot pin for the shackle extending partly through the casing; a bottom plate mounted in the bottom of the casing; means for securing the bottom plate in position; a frame carrying the locking mechanism located in the casing and having an opening for the key hub; a key hub extending through the opening in the casing and into the frame and having a head fitting the opening in the casing; a groove back of the head, the frame being countersunk in a line with the groove of the hub; and a thin plate driven into the countersunk portion of the frame back of the casing, the said plate entering the groove in the hub and locking the hub to the casing.
5. The combination of a hollow casing having an opening in one edge only; a single frame arranged to pass through the opening and to be located within the casing, said frame containing the assembled locking mechanism; a shackle; a pivot pin for the shackle extending through the opening in the casing and through openings in the frame, whereby the frame is properly alined with the casing; and aplate for closing the opening in said casing.
