HENRY GROSS AND JOSEPH L. HALL, OF CINCINNATI, OHIO.
Letters Patent No. '107,174, dcttedSeptember 6, 1870.
IMPRVEMENT IN PERMUTATION -LOCKS. v
*wof The Schedule referred to :in these Letters Patent and making part of the same.
We, HEXRY Gnoss and JOSEPH L. HALL, oi'Gincinnati, in the county of Hamilton and State ofOhio, have invented certain Imprm'enients in Pei-mutation Locks, of which the following is a specification.
Our invention relates to permutation locks; vand 1t consists in a novel arrangement of the parts whereby bnrglars and others are prevented from feeling the tumblers by means of the locking-holt, when the lockis closed, as hereinafter more fully explained.
Figure 1 vrepresents a pla-noi' the interior of a lock embodying our invention, ,showing one series of tinnblers in position to prevent the retraction ofthe bolt.
Figure 2 is a plan ofthe same, showing the relative positions of the various parts ofthe lock when the bolt is retracted.`
Figure 3 is a cross-section of the lock, taken through thc tumblers.
In the douole-tinnblered lock herein represented, the bolt A is provided with two sliding bars, a a,
adapted in form to till the slots in the tumblers when thebolt is retracted.
The vibrating angie-bars B B are pivoted to the v case of the lock, one ou each side of the neck ot' the bolt.
The ends of the vibrating-bars are armed with bars, b b, of a form adapting thcmto fit closely the notches c c in the tumblcrs O G at the time that the bolt is or may be retracted.
Betweentbe pivots d d and the ends of the vibrating-bars are located the pins e e, which engage the check-bar D, and are moved freely in the slots f f of the said check-bar when the bolt is operated.
One end of the bar D is pivoted to the boit at g.
The free end is constructed with asquare recess, t', in its upper face, to engage with the square pillar E when the bolt is out and the bars of the `vibratingbars are not entered in .their recesses in the tumblers.
- of the tumblers, as shown in tig. i. `ends ot the sliding-bars c t1, attached to the bolt A stantially as set forth.
Near the free end of the check-bar D, 'and projecting down from its bottom face, is the finger h, 'which lock, and, at the. same time, in contact at its free end with the pillar E, eii'eetually prevent-s the retract-ion of the boltA when the combination to which the tumblers :u'e'arranged does not prevent the ii'ee entrance of the bars b b into the notches` in the faces In this case the do not rest upon tulel faces of the tumblers, and, cotisequently, no manipulation of the tlnnblers or bolt can be made by. the useof any tools, machinery, or l instrument of wlnttever kind in thel hands of-an expert or burglar; nor can the combination l-e arrived at by degrees, and the bolt ultimately retracted.. 0n-
ly to one familiar with the formula on which the sate or receptacle is to be unlocked can the slots in the tnnrbiersl he arranged to receive the bars b b of the vibrating-bars 15.1%, andthe check-bar D be at libert-y to fall studiciently, (being otherwise held up by the pins'e dit-hat the belt may be retracted, the bars ct c tering freely the slots in the tumbllers. What we claim as our invention isthcrcof en- The combination of the holt A, provided with the the dogs a., and having the check-bolt D pivoted thereto, with the two independent nests of tumblers C, vibrating-hars B, and the indepemlently-operating cam F, all constructed and arranged to operate sub- HENRY GROSS.
