MARTIN L. LAWVSON, OF CHICAGO, ILLINOIS.
KEYLESS LOCK.
SPECIFICATION forming part of Letters Patent No. 666,231, dated January 15, 1901.
Application filed April 16, 1900.
To all whom it may concern.-
Be it known that I, MARTIN L. LAWSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Keyless Locks, of which the following is a specification.
The object of my invention is to provide a keyless lock which may be made of few parts, of small size, and adapted either for practical use or for a toy or puzzle lock.
My invention consists in novel means for engaging and disengaging the shackle by the slight oscillatory movement of the cover-plate -of the lock and in certain details of construction incident thereto, as will hereinafter appear.
The preferred forms of construction are illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of my improved keyless padlock; Fig. 2, a front elevation thereof with a hinged shackle closed and locked and the cover-plate removed; Fig. 3, an elevation of the inner face of the coverplate; Fig. 4, a front elevation of the padlock with the hinged shackle or bolt open and the spring-detent pushed back by the cover-plate, the outline of the cover-plate when in this position being shown by dot-lines; Fig. 5, a front elevation of a padlock with a sliding shackle or bolt closed, and Fig. 6 a similar view of the same with the sliding shackle open.
The lock-case A may be made of any preferred shape or design and is made open upon one side and provided with a pillar pin or stud a and fitted with a closely-fitting coverplate B,adapted to turn slightly upon the stud a and secured thereby to the case, and the inner face of the cover-plate is fitted with a slotted stud a, which embraces the vibratory end of a latch-spring C, thelatter serving both to engage a notch d upon the end of a shackle or bolt D and also serving to hold the coverplate at all times when not pressed aside in its normal position to accurately conform in contour with the outlines of the lock-case.
The spring C has a coil 0 at its middle to give resiliency thereto and also provide an Serial No. 12,989. (No model.)
latch-spring is held to provide stops to limit the movement of the latch in both directions,
thus to accurately adapt the margin of the cover-plate to that of the lock-case.
The shackle is pivoted to the lock-case, as shown in Figs. 1, 2, and 4, and is made to slide therein, as shown in Figs. 5 and 6 of the drawings, and various changes may be made to adapt the novel features of my invention to various forms of looks. The spring-latch, as shown in Figs. 2 and 6, engages a notch on the inner side of the shackle-nose, and the said latch engages a notch upon the outer side of the nose of the latch. This change of detail will require that the cover-plate be pushed from either side to open the lock and makes it more dificult for the uninformed to operate the lock.
The cover-plate may be applied to either or both sides of the lock, and thus serve as a blind and a further means for concealing the modus operand?) of the device. 1
The lock-case may be adapted for a mortise or other fixed lock, and the cover-plate may serve as an escutcheon and operate a springlatch to engage a bolt in any suitable manner.
I claim as my invention and desire to secure by Letters Patent- 1. A keyless lock comprising a case a bolt adapted thereto, a cover-plate movable upon the case and a spring-latch adapted to engage a stud and spring-latch lugs therein a spring- 9 latch coiled to embrace the stud abolt adapted to the case to be engaged by the latch and a cover-plate pivotedto the stud and having a notched stud upon its inner face to engage the vibratory end of the latch-spring, substantially as described.
