. To all whom itrnd concem;

Be it known t at I, JQEN'D. Kenna, a citizen of the United States, residing f at Roselle Park, in the. coui1ty of'Uni'on and, State of New Jerse have invented certain new anduse ul Improvements in Latches, of whichthe .followmg is a specifi cation, reference being had therein to. the accompanying drawings. 4

This invention relatesto-a latching def vice f or separably securing two partsl of a container such as a portable casing for sew machines and the like;

in v. t aims to provides new and i m'provedaccess for manipulation is provided by a counters'unk'opening in oneoi the two sap-- arable parts of the container on whicht e mounted. y

Other objects of theinventionvwill ap' ear. in the following detailed description 0 the accompanying drawings, in which Fig. 1' represents one form of the invention in per-- spective. Fig. 2 represents a cross-section v on line ob,Fig. 1, looking in the direction indicated by the arrows. Figs. 3 and g 4-; represent in plan view a modified construction for the manipulating ends of the lever in non-registering and registering position, respectlvely'. Fig. 5 re resents a cross-section on the lines a-d, F1 3, looking in the direction indicated by t e arrows.- Fig. 6 represents the form of key that may be emplo ed to o erate the manipulatin ends oi t e levers In their form illustrate in Figs. 3, 4 and 5. Fig. 7 represents in perspective the countersunk opening which 5 ,3 IQi'sedpOrtiOILB inwe e!

Thus" it will be s'eenthat there is 'practicalljf no tendency for the hooks to slide away from the keeper under this force andthe liability of their being accidentally released is removed; Because .of th s action the spring 10 may *be a very light one thus. facilitating the manual operation of the books when it is desirable to release them.

It is preferred to form the upper free ends of thejlevers 4 and 5 with manipulating finger- pieces 23 and 24, res ectively, which are slate 1 as imitated Instsid, however, (If shaping the lawns with finger- pieces 23 and 24, itmay be prohired for some pur oses to fashion the not nipulatitbl iids tli lovers with open= ings 26 and 27 which ii'r adapted normally to occupy the relative Positions illustrated in Fig. 3 under the action of the spring 10 when the hooks 8 and 9 are in the position illustrated in Fig. 1.
