from the end portion 15 of the bolt 12.

The 1001: Will then, of course, be opened and the pins 19 will be disposed in the outer portions of the slots 24 of the tumblers as clearly shown in Fig. 3. This being the case on relative turning movement of the plates 10' and 11 with the bar 19 as an axis the tumblers will retain their positions relatively and relative to the bar 16 and pins 19. It will, of course, be understood that the free end portion of the bar 16 is capable of sliding and rotary movement in the opening 13 of plate 10.

Secured to the plate 10 as for example by rivets or pins 26 is a member 27 which extends in the direction of plate 11 across the top of the tumblers and has a downwardly extending flange 28 provided with an opening 29 through which the bar 16 snugly fits.

Since the member 27 is rigid with the plate 10 it is obvious that this member does not move with the plate 11 and bar 16 as the lock is opened and closed. The location of the flange 28 of member 27 is such that the distance between the inner surface of the flange and the plate 10 is suiiicient only to accommodate the tumblers 20.

This member'serves to prevent movement of the tumblers along the bar 16 and when the lock is to be opened the member prevents movement of the tumblers in a direction away from the plate 10. Further, when the lock is opened the pin 19 closest to the plate 11 will engage the flange 28 of member 27 and limit the outward movement of the bar 16 in a manner to prevent the bar being entirely removed from the recess or opening 13 in the plate 10 and from the tumblers 20. This last action it will be understood pre vents the look from being accidentally disassembled.

Means may be provided to prevent casual turning of the tumblers 20 whereby in the opening of the lock each tumbler after adjustmentwill remain in its adjusted position while the other tumblers are being adjusted to position permitting the lock to open. This means as here disclosed comprises a series of fingers or dogs 30 which may be struck from the member 27 and which are carried by this member as clearly shown in Figs. 1, 2 and 3. These fingers 3O engage the enlarged toothedportions 25 of the tumblers and enter between the grooves or teeth therein in such a manner as to prevent casual movement of the tumblers. However there is but a spring or frictional engagement between the fingers 1 and the portions 25 of the tumblers and the tumblers may be rotated against the action of fingers.

Means may also be provided for shifting the plate 11 outwardly or to open position on the tumblers being adjusted to align their slots 2 1 with the respective pins 19. This means as here disclosed comprises a coil spring 31 arranged on thebar 16 in sueha' manner as to engage the flange 28 of the member 27 and to have a portion extending into the recess 18 in the plate 11 whereby to engage the closed end of. this recess. It is open'position as shown in Fig. 3 the plates 10- and 11 may be rotated relatively whereby to leave the end portion 15 of the bolt 12 entirely unencumbered. That is, the plate 11 may be rotated forwardly from the position shown in Fig. 3 while the plate 10 and bolt 12may be rotated rearwardly from the position shown in that figure. This particular action is possible since movement of the plate 11 will result in rotary movement of the tumblers forwardly below the fingers or dogs 30 while movement of thefplate 10 will result in a movement of the said fingers relative to the tumblers. I

In addition to serving to shift the lock f from the position shown in Fig. 1 to that shown in Fig. 2 immediately on the tumblers being adjusted to align their slots 24 with the pins 19 the spring 31 serves to prevent casual closing of the lock. Itwill be understood that the lock must not be closed or that the bar 16 must not be moved through the tumbler toward locking position except when the plates 10 and 11 are in such relative position that the bolt 12 enters the recess 1 1. Otherwise, the combination might be lost with the parts locked in a useless position.

As disclosed the combination of the lock is 2581 ano it will be noted that the plate 10 carries a mark 32 with which the proper numbers are aligned in order to bring the slots 24: of the various tumblers into alignment with the respective pins 19 with which the tumblers are associated.

In assembling the-lock thus far described the bar 16 may have its end disposed in the recess 13 of the plate 10 after which the tumblers are slipped onto the bar. Next, the member 27 is assembled'with its flange 28 about the bar and this member may then be secured to the plate 10 as by the rivets or pins 26. The spring 31 now disposed over the bar and the plate 11 applied and secured as by heading the end of the bar at 17.

Fig. 6 shows a slight modified construction wherein a member 33 corresponding with the member 27 of the embodiment first described is inte ral with the plate 10. This member 33 also has a flange 34 provided with an opening 35*to receive the bar 16. Through its flange 34c and entering into its opening 35 the member 33 is provided with a notch 36 of the dimensions required to permit of the passing of the pins 19 therethrough- V In assembling the lock on a frame such as is shown in Fig. 6 the bar 16 has its passed through the opening 35 in the flange 3st, the notch 36 'permitting'the pins 19 to pass. As the bar is fed through or threaded through the opening 35 the tumblers are applied and the inserted end of the bar finally enters the opening13in the plate 10. Of course, with the use of a frame as shown in Fig. 6, the bar 16 may be integral with the plate 11 and in that event the spring 31 would be applied before the bar was started through the opening 35 of the flange 34 of the member 33.

It is apparent that the notch 36 is shown as 180 degrees from the location of the pins 90 when the lock is closed. Therefore, when the lock is opened by the spring 31 as shown in Fig. 3 the bar 16 will not pass out through the opening 35 butwill have its movement limited by engagement of the innermost pin 19 with the flange 84: as described in connection with the form of invention previously considered. However, this look may be easily disassembled when opened and the tumblers rearranged to give a different combination.
