To all whom il may concern:

Re it known that l, FRANK Somer, n. cit-izen of the United States, residing in `lloila` dolphin, Pennsylvania, have invented certain improvements in Trunlolioolrs, of which the following is u specification.

My invention relates to eerteiii improve-- monts in locking mechanism used particularly on boxes, chests, document enses and lil/Ie articles.

@ne object of the invention'is to provide :i simple and effective, lochv in `Which the look proper is independent oi the bolt.

Another object of the invention is to so eonstrnot the' lock that the bolt mechanism Will return the tumbler to its originel position os soon released from the control of the key, and u still further object is to'sov Width equal to the combined Width Ot thebolt C and the dog D and the endof this projeetion rests against the rear end of the dog when in certain positions. The dog-is notched :it d2 to form a projection d which either rests upon or engages the lug o2 on the bolt. l

j is a spring mounted on one of thepins... o2. @ne erin oi' the spring rests -against n pin 03 on the bolt C and tends to move it forward while the other arm rests against, a. pin al* on the dog D and tends to press the donl down.

lllfhe'n the )arts are in vthe looked as shown in ilig. l, the notched en of the projections l) of the keeper are in engagementnilh the bolt and one of the projectionsl also rest-s against the rear portion of the dog` D, holding in engagement CPosition,

be impossible to yjar the bolt-loose lifter it is thrown to theloclred position.

' In the accompanying d1'aiving:-Figure l, is e sectional yiew of a. metallicjboxillustrating my improved locking mechanism; Fig. 2l, is e view oi? the lock mechanism showing the keeper retracted; Fig. 3, is a view showingr the keeper in line Wit-h thevbolt; the bolt being held by the raised tumbler of the lock; Fig. fl, is a sectional plan View on the lino #iw-fl, Fig. l; Fig. 5, is o. perspeetiye View of the bolt; Fig. 6 is o 1mrspeotive View of bolt cannot. be j erred out of engagement, but as soon as the dog is raised, on the movement of the lever 3, it will be lifted'cleztr of the lug c2 as it'will slide on its pin d; the ends of the Aprojection I) becoming the fulcrum and the bolt will thus be released. Un the continued movement of the lever E, it will move the bolt C longitudinally clear ot the keeper B. The lock pro-per G is preferably made independent of the bolt, as shown, so that any type of look may be used in combination with the bolt. The casing of the look G is made from sheet metal as shown in Fig. 8. On the casing is the T-l1eeded projection L which passesthrough on opening al in the tumbler l; the tumbler having a. shoulder a" engaged by -the projection 7i. The lower end of the tumbler is guided by a. projection which is nd'eptedto a slot 2 in the tumbler. A spring /c 1s secured to the tumbler, as shown in Fig. 9, and presses casing; tending to force the tumbler toward the key hub. This key hub m is mounted in the casina;r and on the tumbler is the projeoftion 1'3 which passes over the hub and -a shoulder 4 which is engaged by the key when it is inserted in the key head and turned.v The tumbler rises from the tion illustrated in Fig. l to thlat illustrated view or' the lever; Fig. 8, is u perspective A is the body of an ordinary metallic document euse and A is the lid hinged to the box in 'the usual manner. Secured to the flange of the lid A is thel keeper B hei/ine` hooked projeotions b which extend through openings a in the bolt easing` a in the pres ent instance.

C is s bolt having three hooks o engaging the hooked projection Aof the keeper and this bolt is slotted at c end through the slots pass pins a secured to the casing. These pins hold the bolt in proper position and allow it to freely slide into either the open or closed position.

D is e locking dog made asshown in Fig. @having an elongated pivot pin opening d for the pin a so that it can rock and slide upon said pin. The dog has a heed d provided -with on inclined surface against against the K central projection l) of the keeper B is of e' the do with'the projection da. Cgonsequently, the

posieer is located directly vin line With the in Fig. 3, by turning the key.

vspring j and the dog will ride upon the lng, but

when Athe keeper is inserted on closing the box, the bolt and the dog will be pushed back by the projection Z) on the keeper and the projection d3 of the dog will drop back of:` the lug c2 and hold the bolt in position es shown in Fig. l. On the movement of the boit by 'the spring f it will act upon the lever E, which in turn will force the tninA hier into theposition shown in Fig. l.

lt will be understood that the locir may he modified without departing from the essential features of the invention.

By the use of my invention l can make a very simple lock which can have one or more hooked projections which may engage the hooked projections on the keeper. The lock is preferably made as a snap loch; the bolt being entirely independent of the main lock mechanism which 'can be oi any type. lhe type shown in thel drawings is very easilfvv and economically made.

The slot in the dogmiist be so proportioned that the distance between the pin and the 'rear end of the slot must be less than the Width of the .keeper projection so that even l if the bolt should move longitudinally when the bos. is jarred the dog Will prevent the inll moveinent of the bolt owing to the end i of :the slot in the dog coming in contact with the pin, thus preventing the opening of the box.

I claim:

l. llhe combination ot 'a heepena sliding bolt adapted to engage the keeper, a pivoted locking dog engaging the bolt and arranged tobe acted upon by the keeper, a si ring actuated lever for throwing the bolt "and lifting the dog,l and a tumbler engaging the lever. Y i

2. The combination in a lock, of a keeper, having a Wide hooked projection, a sliding bolt for the hook arranged to be engaged by the projection on the keeper, a pivoted locking dog arranged to be actuated by the hooked projection and having a projection engaging the lug on the bolt and the locking dog, and a separate locking mechanism for actuating the lever.

3. The combination. in a lock, of a keeper having a series of hooked projections, a easing,-a sliding bolt mounted in the casing and' having a series ohooks to engage the projections of thelreeper; a pivoted locking dog engaging the bolt when in the forward position and arranged to be acted upon by one ot the proiections of the keeper, said bolt and dog being notched, a two-armed. lever pivotally mounted in the casing and having one arm extending into the notches of the lever and dog, with a separate'locl casing, a tumblentherein bearing against the other arm of the lever, and means for actuating the tumbler.

ln testimonywhereof, I have signed my naine -to this specification,
