' TRUNK LOCK.

' tion.

This invention relates to a lock for the side sections of a wardrobetrunk type of box having an open top.

Wardrobe trunks are commonly divided longitudinally into two side sections hingedly connected together, one of the sections having a hinged top. In closing the trunk, the sides are brought together and locked, then the top. is swung into closed position and locked. In opening the trunk,

. the top is first swung open-and then the sides are opened. In order to avoid a multiplicity of key operated locks, the sides have heretofore been provided with a lock operated by an inside rod, accessible upon opening the top. The top has been provided with a key operated master look. Inlocking the sides of such trunks together, it is necessary that the parts be brought snugly together, and then the hinged leaf supporting the master lock swung into closed position. This is often a laborious and a diificult job. The objects of my in vention are, first, to provide alockstructure for the'sides, which will engage the sides before they are fully closed and whose parts are so arranged that they may be used to draw the sides into snugly closed posi tion; second, to provide means whereby closing of the top draws the sides together and locks the same in closed position; and third, to provide a structure such that opening the top automatically unlocks the sides and will start opening of the trunk.

These objects together with other objects and corresponding accomplishments are obtained by means of the .embodiments of my invention illustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary longitudinal section throu 'h a trunk at right angles to the plane of ture, the trunk being fully closed and locked; Fig. 2 is a fragmentary view of the trigger -portion of the structure with the top in partially open position during, the operation of closing; Fi 3 is a fragmentary view showing the si es partially open and with ivision showing'the lock strue Applioation flled April 10, 1923. sum a... 632,281."

the latch about to engage the kee r; Fig. 4 1s a sectionthrough the trunk ta en on the line 02-02 in Flg. 1; Fi 5 is a fragmentary viewin sectionthrougrthe trunk showingthe keeper in'plan; Fig. 6 is'a modified form' of trigger shown in elevation; Fig; 7 is a side view of the structure shown Fig. 6;- and F1 8 isa section as seen on the line y-g o Fig.1.

Referring more particularly to Figs. 1 to 5, inclusive, one side of the trunk having a closed top is indicated by 1. A side 2 is hingedly connected thereto and is rovided with an open top 3. Secured to t e top 3 is a finger 4. extending downwardly and provided with a laterally extending pin 5.

Pivotally mounted upon the side 2 by a 1n 6 is a trigger-6 disposedto be engaged y the pin 5. A pawl 7 is pivotally mounted upon trigger 6, and pin 6' limits the swinging of the pawl in a clockwise direction. A link 8 is secured to one end of the trigger 6 and to a bell crank lever 9, which is pivotally mounted at 9' upon a late 10 secured to the side 2 of the trunk. onnected to the other endof lever 9 is a latch 11 having a rounded nose and a hook to engage the keeper 12 which is secured to side 1. The latch is guided by means of a pin 13 fixed to plate 10 and riding in a slot 14 having an upwardly inclined inner end. The keeper has an abutment 15 disposed to be engaged by the rounded nose on the latch.

Suppose the parts are in the position the trunk. The top is swung into open position. In the opening movement of the top, finger 4 and pin 5 are swung upwardly so that the latter engages the pawl 7 The pawl cannot be moved clockwise upon the trigger 6 and therefore causes the trigger to be'swung in a clockwise direction. This depresses the link 8 and swings the lever 9 into the position shown in Fig. 3. Swinging of the lever causes the latch 11 first to be protracted longitudinally, forcing the trunk sides apart as shown in Fig. 3 by reason of the latch pressing against abutment 15. At the end of the longitudinal movement of the latch, the pin 13 rides into the inclined end of the slot 14 causing the latch to be swung so that the hook moves out of the slot in the keeper, thereby unlocking the sides. At the upper end of the movement of the trigger 6, pin 5 on finger 4: will ride from beneath the pawl 7. In closing the .90. shown in Fig. 1-, and it is desired to opentrunk, top 3 is brought into closed position- The pawl 6 is disposed in the ath of pin 5 and the latter may pass it'ias s own in Fig.

2. The pin 5 then enlgages'the trigiger 6 and swin s e latter so t qt. link 8 is rawn upwardly to the position shown in Fig. 1. Lever 9 is swung from the position shown in Fig. 3, firstcausing the latch 11 to be swung upwardly so that the hook engages keeper 12. Thereafter, continued movement of the latch due to pressure upon the cover 3 causes the latch to be retracted longitudinally bringing the

sides

1 and 2 together. The pin 5 rests upon the finger 6 holding the latter in its locked position so that the sides cannot be opened. B locking the cover 3 closed, the sides are a so maintained closed.

Referring particularly to Figs. 6 and 7 a modified form of structure is shown wherein the lock may be operated from a key and not from the cover. A leaf 16 carrying a master lock is hinged to a section secured to a pivot pin 17 Thus, the leaf may be turned to -be in line with its keeper and then swung into locked position. Pin 17 is pivotally mounted in side 2 and is secured to an arm 18 mounted on the inside .of the trunk; Link 8 is pivotally secured to arm 18. It is obviousthat by turning leaf 16 the lock for the sides is operated. When the leaf is in position to be locked the lock for the sides is locked.

While I have disclosed my invention as able mechanical changes being made where necessary.
