Speciiicaiion*forming part of Letters Patent.No.,ri,7.25,.,idaigedllovetuberidisegi. l

, Fg.-2 represents the saine as. with one side of -thencase removed. Fig. 3 is a vertical section transversely of the lock. Fig.- 4 is the key; land Fig. ,5,is a lrn'odiiieation of my improvement,

showing the same as' applied to a lock for draws", doors, `&c. 1

Similar marks of reference denote the same tween the parts of the pins are in line with the parts ofthe lock to be. turned oneach other.

The nature of my said invention consists in a lock-case of two parts fitted vto screw or lock together and prevented. from turning by Itheloolt or'hasp, in combination with stationary and turning blocks containing divided stop-pins, whereby the position oi' said pins can bejehanged to eti'ect a lpermutation of the lock by Vopening the case when unlocked. I

also make use Iof a lcurved hook-bolt extending vfrom the turning block to the curved interior of the lock-case, whereby said hook-bolt is sustained by said ease,'and strain from the hasporboft on said' hookis not taken on the divided stop-pins; thereby the lock is rendered less liable to be picked,.because the turn-ing block cannot be strained sidewise by pulling on the hasp or bolt. Y

l[n the'drawings, a and b are the shells of the lock, which are vscrewed togetlieigasv at c, or

secured by lsectional inclined or screw-formed lugs withinv the case; and i is the shackel or bolt, hinged at c, and' entering niortises in the parts c of the case, so that the'case cannot be unscrewed or taken apart when the lock is locked,"the same as shown in my patent of Augusto, 1862."

Secured upon or formed with the case ais a block.

block,j=',^tha'tfis formed circular around its flatendfand receives'the rear flat circular face ot"- the moving block g. Ati the block g is formed with acircular flange surrounding the blockf, lso that the block (j can be turned upon f, but will be held in position with the same by this iiange i. It will be seen that i'or this purpose thecircnlar flange i might be on the block j' and a circular recess in g.

h h arcdivided stop-pins in fandg, kept'forward by the springs lc,- and l l are holes at the ends ot' the pins h h, that are smaller in size than such pins, so that the springs 7c cannot eject the stop pins 71., but at the same time the pins mA m of the key 'n can pass thron gh such.v

holes and ,act upon the stop-pins. The divisions between the back and front portions ot' the stop-pins h are at-such points that when the key-pins m are pressed against the ends ofthe pins /L said divisions .are at the point wherefand g come together, and hence the block g can be rotated for unlocking' the lock, but when the lock is locked the rear portions of the divided stoppins projectinto the holes ing, and said block g cannot be turned; hence the lock cannot be opened until the correctkey is applied to press eachstop pin back its own proper distance. Upon this block g, or actuated by it, is the bolt or hook o; that in Figs. 2 and 3 is shown ofa character-to enter a, mortise in the'V shackel dk and retain the saine, while in Fig. 5 this bolt o is shown as pro'- jecting beyond the lock-shell a in a manner that would be required ier a door-lock or a lock for draws, boxes, Sac.

p p are stops to determine the amount of motion allowed to the block gland hook 0, Fig. L'. The shellb when screwed on retains the block g in its plaeeby the shoulder, asseen in Fig, 3, but at the saine time the black g can be turned by the key n. l provide a groove, r, across the front face of the block g,-.whicl1 fa- 'cilitates the entrance ofthe pins in oi' the key into their respective holes, and at the same time receives the flat platevforming the key,

so that thepins are relieed in .turning said When the case a. bis together, the

hook or bolt o, Fig. 2, moves contiguous to'l ,the

inside Aof the case b, andhenceis supported bj,

said case when` through the mortise infth-I It will be evident that this lock canveasilv be taken spuit and the divided sion-'pins changed into different holes, so that the look is adapted to :i key with the leng'tiisofpins dii'erently p1aeed,' s othat a loekean'be made secure alt the expense of a. new key in veuse of Y'the former key being losli:V or stolen. Having thus described myA said improve# ments, what I elaim, and desire vto secure by stop-pins n'd *adnl'iting them for adibent key, as setforth.

the `turning block and contiguous tozind supported, by the curved interior-of the look-ease,

, in combination with the divided stop-pins and with th'ehasp onboll,v whereby the strain Von steado he `divided. pins, as specified.`
