ative parts of the lock. The several discs andplate 19 are uniform in thickness and have immediately below v them a bottom plate 30 tightly fitted in the casing, the plate having an opening 31, through which the lug 32 extends to move limitedly endwise of the casing.

Adjacently below the plate 30 is a pressed metal box-like casing 42 having fiat extended ends 33 containing openings 34, through which the prongs 18 pass, thereafter being bent to clamp the structure rigidly on the frame side, as best seen in Figure 2;

Opposed pairs of lugs 35 are bent inwardly towards each other from the edges of the casing 12 and on which is movably seated a channel shaped slide 36, the same having an opening or 90 receive the end of the lug 32, by

which motion may be transmitted to it.

'The slide or keeper 36 isprovidedin its front wall with spaced apart openings 37 to permit the entrance of thecatches 14, the

same also passing through openings 38 in the front wall of the casing A2,;

' respectively tothe casing 12 and keeper slide 36 by a pin 40 maintains the lock in a normally closed position, but perinits the slide to move against the spring when the catch elements 16 I are, forcibly presented in the openings 37, and also whenthe central knob 25 is manually actuated to moveitlie slideby reason of the plate 19 and its lug 32.

The severaldiscs are corrugated near their tops to aid in manipulation and are provided with numerals on theirfaces to register with a line 41 on the. top of the casing.

As has heenseen, the sides of the bag may be closed at any time without respect to the position of the dials, causing a locking effect between the keeper slide 36 and catches 1 1.

=When it is desired to unlock the bag, the

knobs 29 and 29 on the outer casing must be positioned to bring the disc notches EFF-'27 into register with the lugs 21- 21, permitting the central knob 20 to be moved and 45 carry with it the plate 19 and keeper slide 36 in the inner casing, thus freeing the catches to permit their withdrawal, the spring returning the several parts to their normal engaging position when the pressure is released.

Obviously the plate 19 and lugs 2121 prevent moving the knob 25 whenever the discs 2626 are rotated into other than aposition to receivethe lugs, thereby constituting an essentially safe and simple form of lock.

Although the preferred embodiment of this invention has been explained in detail, it is to be understood that changes therein may be made without conflicting with the scope of the appended claims.
