ful Improvements inlldadlocks5,` of` which the following `is a vspecificationb"^`^ This invention relates to improvements in portable locks adapted to engage with a staple or the like whereby,l a latch may be The principal object of the invention is to provide a lock of the permutative kind, having a pair of disks adaptedto be rotated from the exterior of the lock into definite position, so that the tumbler may engage within sockets formed therein.

A further object is to provide means which prevent the release of the bow of the lock, irrespective of the position of the disks, except that it must be first moved so as to free the coupler. v

These and other like objects are attained by the novel construction and combination of parts hereinafter described, and shown in the accompanying drawings, forming a material part of this disclosure, and in which-.-

Figure 1 is a front elevational view show- .taken immediately below the cover.

Fig. 3 is a similar view of the same,the interior parts being in different positions, and j Fig. 4 is a transversesectional view taken on line 4 4 of Fig. 2.

Referring to the drawings, the lock is seen to comprise a body representing two squares, superposed one upon the other, presenting octagonal `points 10` and 11, to which the cover 12 is secured by rivets 14, and containing an opening 15, in which the mechanism is disposed. d i

"()ne of the points or blocks 16 has an inwardly extending stein 17, slidable within an elongated slot 18 formed within the edge of the lock and yheldin position by a nut 19 screwed upon the end ofthe stem.

rthe bow 20 is pivotally engaged` within i the lock body bythe rivet 21 and is freniiocx, j, d,

`Theinner projecting end 30 of the tuiiibler is engageablewithin recesses or sockets i 32 "and33, formed in the periphery of a pair of disks and `35, ,journaled to` rotate `witliin"the casing, the "`disk"35 being "positioned against the lower inner surface `of the body 15, and is provided with an extending stem 36, the same passing through the cover plate 12` and provided with a lever arm 37, simulative of the ininute hand of a clock, the same being rotatable with reference to a plurality of circular graduations 38, `formed upon the exterior of the casing 12, and by which it may be definitely located iii an adjusted position.

`The other disk 34, through which the stem 36 passes, has an extending sleeve 40, secured to which is an arm or lever 41, representing the hour hand of a clock, and also registerable with the graduations 38. Thus by rotating the levers 37 and 41 into a definite position relative to the graduations the recesses 32 and 33 may be brought into registration with the extending arm 30 of the tumbler, so as to permit the same to enter the recesses, whereupon, due to the action ofthe spring 28, the engaging hook element 25 isremoved from the recess 24,

permitting the bow ,of the lockto be raised,`

normally however, this isprevented in the following manner.

A recess 44 is formed with the tumbler 26, adjacent to the arm 30, vand engageable within vthe recess isthe hook detent 45 of a lever 4G, pivoted on the pin 47 within the lock casing, the outer end of the lever having pivotally engaged with it a link 48, its outer end pivotally engaged with an extension 49, the same` extending from the stem 17, formed with the sliding element 1G. h From the foregoing it will be seen that a novel and eifective form of perinutative lock has been disclosed, having in addition tothe usual features the sliding block 16, which must be properly manipulated before `the bow is released, therefore one merely familiar with the permutative features of the lock, is still unable to release the bow unless he has yprior knowledge of the movement necessary to impart to the block 16.

Having thus described my invention, what I claim as new and desire to secure by Let-v ters Patent, is-

In a lock of the,class described, the combination with a poly-pointed body, a cover thereover, a chamber formed in said body, and a bow pivotally engaged in said body, the opposite end of said bow to be enterable through an opening formed in the edge thereof, of a pair of disks rotatably engaged'in" said chamber, said disks having transverse recesses formed in their periphery, an annular row of graduations formed on said eover, elements engaged with said disks extending through said cover, and adapted to be kbrought f into reg# istration with any of the graduations Copies of this patent may be 'obtained for ive cents each, by addressing the impressed thereon, a tumbler pivoted in said body, said tumbler having a part engageable with said bow, an oppositely disposed extension formed with said tumbler engageable in said recesses when in alinement, a spring adapted to press said extension into engagement, a detent pivoted in said chamber, said detent having a portion engageable with said tumbler, whereby it is held in an operative locked position, a block slidably engaged on said body, said block having a stem extending through a longitudinal slot formed therein and an operative connection between said stem and said detent whereby the detent may be re- 'v moved from engagement with said tumbler upon actuating said lock.

In testimony whereof I have aixed my signature.
