T0 ALL WHOM IT MAYONCEItN:

Be it known that I, JOSEPH Nooit, of the city of Washington, in the District of Columbia, have Ainvented new andu useful improvements in Trunk and. Chest-Locks; and I do hereby declare the following to be a full and exact description of the same, reference being had to the drawings that accompany and form a part of these specifications, in which- Figure I, view of the lock from the front.

Figure II, View of the hasp, looking at the under side thereof.

Figure III, plan view of interior, showing position ot` parts when the bolt is thrown back so as to withdraw the hasp. I

Figure IV, view of the same parts, with the bolt thrown forward as when the trunk is locked.

Figure V, sectional view, showing manner of combining the bolt with the' actuating lever.

FiguregVI, of hasp with hooks bevelled so as to make it self-locking. l

Letter A, lock-plate; letter B, hasp; letter C, haspplate; letter D, bolt; letter E, crooked lever, acting in combination with the tumblers I and the bolt D; letter F, series of tumblers; letter g, key; letter i,pin, on to which the hooks t't'of the tuuiblers F clasp to effect the looking; letters jj, bevelled hooks on the bolt D, so that the hooks 7* r on the hasp B may slip in place merely by pressing the hasp inwards; letter c, spring to keep the bolt D in place letters Z Z, staples Aon the hasp B, dili'ering from 1' r in Fig. VI, and requiring the use of the key to lock or move the bolt; letter m, spindle, on which is coiled the spring n.

It will be readily seen by the drawings that my invention applies to two different styles of locks, the one self-loclting, and the other n ot. i

My invention consists in the manner of combining and arranging the bolt D, the lever E, and the tumblers F, as also in *providing against the injury that so often comes to the hasp of trunk-locks by the use of the spring n. l

In the interior ot the stile that is not self-locking I do not claim anything as especially new; but the arrangement seen in Figs. III, IV, and V, by which a series of tumbler-s is made applicable to a self-closing lock for trunks and chests, I consider entirely new.

In Fig. V a portion otl the lever E is cut away, that the pin or stop s, which throws the bolt D back when the lover is raised by the key, as in Fig. III, may be seen. The use of a. spring for throwing out the hasp is not new. My improvement in this respect consists in the manner of fastening the spindle min the swell of the hasp-plate C. Fig. II will make this plain. The two ends of this spindle have a attened surface at O, so that by placing asmall block on this attened side, between the jaws P P, and hammering down these jaws, as seen at the opposite end, the spindle is kept from turning, and the spring 11, with one end fastened to the spindle m, the other resting against the hasp'B, operates to throw the hasp out whenever the bolt is withdrawn, as seen in Fig. I. The spindle mbeing wholly embedded in the swell of the hasp and hasp-plate'eannotbe forced out, as has been the ease with other locks of this kind of' hasp.-

I believe these locks of mine to he more safe than any other trunk-locks in use, and yet they are very;

simple. It is not necessary for me to enlarge upon the great degree of security these locks a'ord, for what has been said of my inside trnnkloeks for which I am seeking Letters Patent is applicable to these.

What I cla-iin as my invention, and desire to secure by Letters Patent, is-

1. The use et' the crooked lever E, or its equivalent, in combination with the tumblers F, more or less in number, and the bolt D, arranged substantially as described and shown.

2. I claim the spindle m' with the spring n, when inserted and confined in the hasp, substantially as described and for the purposes set forth.
