TRUNK-LOCK.

Specification of Letters Patent.y Ptenfed APL 11, 1916.

Application med December 2a, 1915. serial No. 68,975.

,To all whom it may concern bers of a trunk at several points along itsy length by the loperation of a single lock which is opened and closed in the ordinary way. f

lt is known to provide a plurality of locking devices whose operation is controlled from a single lock; but such lock is specially constructed and mounted and requires a double operation to cause it to edect complete locking or unlocking. 1t is also known to provide a plurality of hasp members hinged to the cover of the trunk, one of which members is controlled by a key and is operated to move a locking contrivance into and out of operation with the other hasp members; but this construction necessitates the f operation of both hasp members in locking the trunk.

In my invention, I have simplified both the construction and the mode of operation,

the latter involving merely a single Inove-v ment of the locking hasp member in one direction to lock the trunk and a single movement of the locking liasp member in the opposite ydirection to release all the securing devices. The construction, moreover, is

-such as to permit of an arrangement 404 whereby the key-controlled hasp is located midway of the length of the trunk and con- 'trols securing devices at opposite ends. The .construction also .lends itself to the location of the key-controlled hasp near one en'd of the trunk, which arrangement 1s more con- A venient in the ca'se of a wardrobe trunk.

sectional V elevation looking Preferred embodiments of the invention are shown in the accompanying drawings,

in which- Figure 1 is a front view of a trunk with my invention applied thereto. Fig. 3 isaJ from the inside toward the front of the trunk of Fig. 1. Fig. 3 is a detail view, partly in section, of the key-controlled lock of the trunk of Figs.

1 andQ. Fig. 4 is a front view of a wardrobe" trunk with my invention applied,l

thereto. Fig. 5 is a sectional elevation look-"y *ing from the inside toward the front 0f the trunk of F ig. 4. Fig. 6 is a detail View` partly in section of the key-controlled lock oftheV trunk of Figs. 4 and 5.,

The trunk of Figs. 1 and 2 comprises a body a anda cover b. The locking hasp, which is of ordinary construction, is hinged to the body a and has a flanged member c and a barrel (l. lVhen the hasp is closed, the flanged member c-engages t-he escutchcon f on the cover b while the barrel d enters into registering orifices in the escutcheon and in the wall of the cover. The bar-- rel contains 'the' usual spring-actuated sliding bolts e, e, which, when the hasp is closed, engages the wall of the cover, there- .Y b v holding the hasp in locking position. The bolts e, e, arereleased by a key.

'lheabove construction is well known and need not be described in further detail.

On the inside of the trunk cover I have provided two longitudinally extending slidable bars g on opposite sides of the central lock. Each bar is pivotally connected to a. n

wall, guide the bars in their sliding movement. The outer end of each bar has an extension n, which is slidable in a bracket o. A coil spring p is confined between this bracket and the end of the bar Aand tends to move the bar inwardly toward lock.

Secured to and projecting beyond the barrel of the lock is a triangular shaped cam r, opposite cam faces of which, are adapted to engage the inner ends of the bars g,`when the main lock is moved to its clos-' ing position as shownin the drawing, andv move and hold the bars in their outer positions, in which positions the hook members h engage the loops j, thereby locking the cover and body of the trunk together at the center and at the ends. When the key is turned to release the bolts e e and the hasp swung on its hinge away from locking position, the springs p act to move the bars g toward each other, thereby withdrawing the hooks h from the loops j. Thus, by

-whereby the greatest by the cam with the east strain upon the operating the regular locks in the ordinary which is the location best adapted for con- 3o way, the vother securing devices will be'si multaneously locked or unlocked, avoiding both especial manipulation of the main lock and a' special operation of an additional locking hasp.' It will be observed, also, that the lock need dil'er neither in 'construction nor operation from the ordi- -nary lock and that the bar-actuating cam is added thereto without modifying its structure. Therseid cam is mounted directly on the locking barrel, in such central position that the outer edge of the cam alines with a line bisecting.. thev hasp longitudinally, ower can be exerted has v 'fille construction shown in Figs. 4, 5 and 6 correspondswith that shown in Figs. 1, 2 and 3 except in the following particulars. There is only a single bar g, which operates two hook members Il, located respectively at tlmA center and toward the bottom of the trunk ln place of the two faced cam i* there is substituted a single faced cam s, whose outer edge, however, is, like the outer edge of the cam 1', located preferably centrally of the barrel d. The main lock'is located toward the upper edge of the trunk,

vement manipulation.

Having now fully described my inven tion, what l claim is:

ln a trunk, the combination with the two hinged sections thereof, of a main locking device hinged to one section on an axis extending longitudinally oi the trunk and adaptedv to swing toward and engage the other section, a fixed locking member secured to the section to which the main locking device is hinged, a complementary movable locking member adapted to engage the xed locking member, a longitudinally extending actuating bar for the movable locking member, said movable locking member and its actuating bar being' carried by the other section of the trunk, and a cam carried by the main locking device and adapted, as the' same is swung into engagement with the second section, to actuate said bar and thereby cause the movable locking member to engage the fixed locking member on the rst named section.

In testimony of which invention` l have hereunto set my hand, at Philadelphia, on this 18th day of December, 1915.
