Specification of Letters Patent.
Patented July 14, 1908.
Application filed June 11, 1907. Serial No. 378,365.
To all whom it may concern:
Be it known that I, CHARLES A. ERIOHSON, of Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Im rovements in Padlocks; and I do hereby dec are the followin to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in padlocks, adapted to be unlocked by a flat key, the object being to provide simple and effective means for changing the key way so that keys designed for onelock will be inefiective in any lock except particular ones having gates corresponding to the wards in the lock,
A further object is to sim lify the construction of locks of this class by locating all the mechanism of the look within a frame, which when assembled within the-metal shell holds the operative parts in osition without the employment of securing evices;
A further object is to provide a lock-of the character described that will be simple in construction, and effective in use, and one in which the shackle is held in its locked position by two inde endent locking devices.
With these en s in view my invention consists in the parts and combinations of parts as will be more fully explained and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view in side elevation of the lock one side of the sheet metal frame being removed. Fig. 2 is a view in transverse section taken through the chan cable ward of the lock, and Fig. 3 is a view 0% the frame, one face or side being removed showing the operative parts assembled therein.
1 represents the shell or case approximately a crescent in shape with flat sides, and open from side to side, the opening in the shell or case also being of crescent shape. The concave portion 2 of the shell, which 00- operates with theshackle 3, is slotted for the reception of the latter, and a key opening 4 is provided at a point diametrically opposite the concave portion 2.
A depressed shoulder 5 is formed in each side face .of the case around the o ening therein, each shoulder forming a seat or one face plate of the lock. One face plate 6 carries the combined spacing plate and key shackle in its locked position.
The key stop 7 and Ward 8 extend nearly the width of the plate 6, and both are slotted at 12 for the assage of the shanks 13 of the shackle 3. T e combined spacin plate and key stop 7 is provided at its en s with the head 14 adapted to pass through slots in the opposite face late 6*, and be upset thereagainst for lo iing the two plates together. The fixed ward 11 is also provided with a head adapted to pass through a slot in plate 6? and be upset thus assisting the part 7 in holding the two plates 6 and 6 in proper positions against the opposite faces of the shell or case 1.
Located between plate 6 and key stop 7, are the two bolts 15, each of which is slotted for the passa e of a shank 13 of the shackle 3, the two shan s 13 being recessed as at 16, on their outer faces to receive the bolts 15, which when seated in the slots, hold the Located in the rear of each bolt, is a V-shaped spring 17, which hearing at one end a ainst the shell or case 1, and at its other en against its bolt,
'yi'eldingly holds the latter in contact with its shank of the shackle. By introducing a key between the adjacent ends of the bolts, and forcing the latter outwardly, the shanks of the shackle will be disengaged and shot outwardly to its 0 en position by the spring 18, which is seats on the post 10 and bears at one end against the case or shell and at its other end against the pin 19 secured to one shank of the shackle.
The ward 9 is notched or slotted to permit the key to enter therein and. as shown is located intermediate the fixed wards 8 and 11. This ward 9 is secured at one end only and it will be seen that when its position is changed, the key bittings must also be changed, hence while the locks of this type are all duplicates as to the several parts, a simple change in the location of the ward 9 seals the lockagainst all keys of the same type except those having a hitting conforming to the changeable ward 9, and as the latter can be moved to any position intermediate the fixed wards 8 and 11, a great number of changes are provided for.
The ward is not changeable in the sense .that after the lock has been once assembled,
it can be taken apart and the position of the ward changed, but in the original construction of the lock, the ward 9 may be located at any point intermediate the wards 8 and 11 and thus produce a lock which is identical as to parts and identical as to construction with others of the same type except as to the location of this one ward, and as each change in the position of the ward necessitates a change in the key bittings, it will be seen that a great many changes are provided for. Again I may employ two or more changeable wards intermediate the wards S and 11, and in this Way multiply the number of changes.
After the bolts and springs have been as sembled on the plate 6 the. case is slipped over the parts thus assembled, and are secured by placing the plate 6 on the heads of the spacing plates and upsetting the heads.
The case or shell 1 is provided on its inner face with the shoulders 20 between which, the ends of the combined key stop 7 and fixed ward 8 rest, and which assist in holding the parts against any movement after they have been assembled.
In the lock each shank is engaged by a spring pressed bolt, the bolts engaging the outer faces of the shanks, and are released from the latter by a key entering between the bolts and separating the latter. If therefore the spring of either bolt breaks, the other will operate to lock the shackle, consequently it is only when both springs are destroyed that the lock becomes inoperative.
It is evident that many slight changes might be resorted to in the relative arrangement of parts herein shown and described without departing from the spirit and scope of my invention hence I would have it un- I derstood that I do not wish to confine my self to the exact construction of parts shown and described, but,
Having fully described my invention what I claim as new anddesire to secure by Letters-Patent, is
lock casing and a shackle having two shanks, of a bolt engaging the outer face of each shank, the inner ends of the two bolts terminating between the shanks in a position to be engaged by the key, and means for yieldingly holding the bolts in position to engage the shanks.
2. In a pad lock the combination with a shell or case, and a shackle having parallel shanks, of parallel plates within the shell or case at right angles to the shanks, and spring pressed bolts located between said plates and engaging recesses in the outer faces of the shanks of the shackle.
shell or case of approximately crescent shape externally and internally and provided at its sides with recessed seats, and a sliding shackle carried by said shell or case and having parallel shanks projecting into the latter, of connected face plates seated on, said recessed seats, and a sliding bolt for each shank each bolt engaging a recess in the. outer face of its shank.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
