When, the hasp is released, the spring 10 22 will operate to rotate the rod 14 to move the teeth 15 of the rack out of engagement with the spring 16 and thus permit the free upward move- 7 ment of said rod and the opening of the cover part 11 which may be moved into a fully opened position by releasing thelatch device or devices at the back of the body part 10.

The latch devices at the back of the body part 10 difier tromathose atthe front in eliminating the hasp 26 imdits associate parts. as well .as in eliminating the block and spring 22. The casing 12a of these devices are the same as the casings 12 and include the spring fingers 16a which I operate in connection with the. teeth 15a of the rod 14a. g r

The rod 14a includes a knurled portion v32 ad-' jacent the upper end thereof by means of which said rod may be rotated to move the teeth 15a out of engagement with the spring finger 16a permitting the upward movement of said rod with respectto thecasing as will be understood. vA ball end 33 is provided'at the upper endof the rod 14:: which fits ina hollow block 34 secured to the top cover part 11 to providea pivotal or hinged connection of the cover part with respect to the rod or rods 14a, said block having'slots 35 formed .intwo walls thereof toreceive the shank portion 36 of the rod 14a adjacent the ball 33; permitting v -themovement of the cover part 11 into the position shown in Fig. 4. of the drawing, it being understood at this time that the block'34 may be no'slotted as to vary the opening. movement of the partllif. desired. I

. .It willbe-understood that in packing the body parts 10-and;ll after the articles have been placed .therein,.the part 111 will be moved'in'toa position I above the part 10 and the rod 140, rotated to bring the'sameinto the position shown in Fig. 1 of the .-drawing, and the hasp26 of the rod 14 will be 1 coupled with the lockcasing, in which operation,

the-hasp is rotated .to place the spring 22 under tension as said .hasp is moved fromthe position 'shown'in-Fig.'2 tothat illustrated in Fig. 1.:

Withthe parts thus assembled, the top-body part is forced'downwardly, causing'the rods l4---l4a11tov descend in the casings 12, 12a, the

spring fingers l6, 116d. passing over the teeth 15, 15aioIthe rods untilsuchitime as the articles are fully compacted within the body parts, after which the-downward. pressure is released and the shown at the front and rear of the case as in Fig. 1. In this construction,..I eliminate the necessity of employingthe teeth l5, 15a and the "spring fingers" 16, 16a, and substituted therefor I employ a cam lock plate 37 pivotally supported in connection with, an extension on the back plate l'lb bf-a casing 121) above the top plate 18b of said casing and adapted to earn locklwith a rod 14b movable vertically in thecasing to support said rod against upward movement, atthe same time permitting downward movementof the rod .at any time. Thecam plate .37 is supportedin its operative position by a spring 38 arranged between the" lower face thereof and the top plate 18b of the casing. In order to permit upward -movement of the rod 14b; all that is necessary is to depress the plate 3'? againstthe tension of the spring "38th release said 'plate from the rod.

With this form of construction it will be apparent that the hasp will be attached to the upper end of the rod on the front latch, whereas the rearlatchwillhave the ball-end or similar means for providing a pivotal or hinged mounting of thetop part 11 in connection with the rod. r

. It will be understood that various other changes in an'd modifications of the construction hereinshown and described may be made within the scope of the appended claims without departing from thespirit of my invention or sacrificing its dvantages.
