LOCK.

Specification of Letters Patent.

Patented July 5, 1921i.

Application filed August 28, 1919. Serial No. 320,521.

To all whom t may concern:

Be it known that I, FRANK ELLisoN BEST, a citizen of the United States, residing at 3210 33rd Ave., So., Seattle, in the county of King and State of ldashington, have in vented a new and useful Lock, of which the following is a specification.

My invention relates to improvements in locks and especially to one for which l filed anapplication April 24th 1919, whose Serial Number is 292,365, to which these improvements are directed. v

The objects of my improvements are; first, to provide in a secondary lock which controls the assembling and disassembling of the locking mechanism, annular operation instead of axial to eliminate certain rea sistance to the removal of the primary key.

caused by the shearing tendency of the secondary locking lshears upon the pins due to the natural tendency of the core to removey cilitating their ie-insertion into the device;

fourth, to provide pin tumbler combinations suoli that one, key may operate both the primary and secondary locks bybeing in serted to different positions; fifth, to restore the face of the lock to thesolidarity of an ordinary pin tumbler and cylinder lock; sigrth, to provide stronger interlocking mechanism between the case and the core; seventh, to provide a shorter lock; eighth, .to

reduce the number of parts; and ninth, to retain all of the advantages of the lock :referred to. V

l attain these objects by mechanism illustrated in the accompanying drawings, in which.-

. Figures 1 and 2 show Vertical longitudinal sections of the device taken through the center with the key in the twoy differentv positions required to operate the primary and secondary locks respectively. Fig. 3`

shows a section of the lock taken on line DD, Fig. 5.

Fig. 4:, represents a section. taken on line BB, Figs. 1 and 3. Fig. 5 shows a section taken on line CC, Figs. 2 and 3. Fig. 6 shows the same section with the secondary lock unlocked ready for the removal of the core. Fig. 7 shows a section taken on line AA, Fig. 1. Figs. 8 and 9 represent isometric projections of the two main units of the lock, the case and the core re-- spectively.

Similar letters and figures refer to the same oi; similar-parts throughout the several views. j

The case 1, Fig. 8, may be secured in any ordinary manner to a door or other object to be locked and the core, Fig. 9, may be inserted and locked therein and unlocked therefrom at pleasure.

The core contains the locking mechanism of a primary and a vsecondary lock. The primary lock performs the usual functions of a lock while the secondary lock controls the insertion and removal of the core from the case. Y

The core possesses a frame 2, Iforming the face of the lock and extending backward through the device, carrying other members adjusted thereon. To frame 2 is `adjusted eccentric sleeves 3, integral with which gate t; which for convenience in manufac ture may be brazed thereon. Prongs 5 of frame 2, fitting into holes in gate or locking projection et, facilitate the adjustment of eccentric sleeve 3 to frame 2 and permit a limited annular movement of the one relative to the other, while preventing any othermovement. Passing through a hole in the face of frame 2 and througheccentric sleeve 3 'is key cylinder 6 into which is mortised and housed throw bar 7 which, in turn,

secures said key cylinder in place, .Throw bar 7 is secured in ,place by an extension 8 of eccentric sleeve 3, and also by case' 1 when cylinder inverted from its osition as shown in thel several views. T is permits said -throw 'barbeing inserted upward or withdrawn downward between the open ends 9, (Fig. of the crescent, whichprojection 8 lof eccentric sleeve 3 forms at that section.

Gate 4 is provided with teeth- 10, Fig. 9,`

which engage with projections 11 in case l,

lic

thereby securing the core within the case as shown in Figs. 4 and 5. l

The lock is provided with pin tumblers 12, and balls 13, operating in the usual multiple pin tumbler barrels 14 of which there are five in this instance.

A one piece capping device is employed consisting of frame 15 to which plugs 17 are riveted or otherwise secured after ends of springsl are closely fitted about the neck thereof for inclusion in the securing process, Figs. 1, 4, 5 and 6. The capping device `is also provided with projections 18 which fai cilitate its removal by thumb and finger. It is also provided with projections 19 one of which fits into a groove 20 in gate 4 of eccentric sleeve 3 forv the purpose of preventing the removal of the capping device when the core'is beingremoved or inserted into the case. The capping device is made symmet- /rical to render it reversible.

The shearing line of the primary lock is at the upper surface of the key cylinder and the yshearing .line of the secondary lock is at the upper surface of the eccentric sleeve.

When a break in the pins of each barrel is alined flush with the upper surface of the key cylinder 3 by means of a key as shown in Figs. 1 and w4, the primary lock is operable,- controlling the throw bar, while the secondary lock remains locked. By alining a break in the pins of each barrel flush with the upper surface of the eccentric sleeve as shown in Figs.. 2v and 5, the primary lock becomes locked while the secondary lock be,- comes operable, making possible the disei1- gaging ofthe gate 4 ofL eccentric sleeve 3 from projections 11 of case 1 as ,shown in Fig. 6, in whichposition `the core may be withdrawn. axially from said case as shown in Figs. 8 and 9. Upon withdrawing the core, the pin tumbler barrels may be lrealined making possible the removal of the` capping device and subsequently the pins and balls from the barrels for the purpose of changing the combinations of the device,'

or disassembling it.

It will'be apparent that by selecting. pins,

' ofproper length, thec lock maybe so adjusted that one or anum'ber of keys' may operate either than primary or secondaryi lock, or a key may operate either without operating the other or may operate both when so,` desired. For instance, in a certain lock, a dozen different keys may operate the primary lock, while the secondary lock is op- `Ierated only by onekey and that one different from any of the said dozen.

"Ihis device makes itpossible for an individual to adjust several locks to operate by one key thus removing the necessityof carrying a large bunch of keys and laboriously seeking the right one in the dark. It also makes possible changing the lock so that the finder of a lost key or a former tenant cannot operate the lock. It makes desired changes practical, even within a complicated blerfcombinations so that there will be as j desired combinations can readily be set up,

and by employing a key fitting punch such as the one for which I filed application, May 16, 1919, whose Serial Number is 297,604, a new key to match the lock can readily be obtained also.

. In conclusion I wish to'have it understood that I do not limit my inventionto locks of any definite number of tumbler barrels or in any other way. l

Having thus described `my invention, what I claim 'as new and desire to secure by Letters Patent of the United States of Americais: f Y
