The desk with the doors 2, 3, for compartmentstherein, as well as drawers 4:, 5, for additional cabinet compartments.- The drawer 5 is provided with the opening grips or handles 6, which in heavier work may be the real .bolt actuating means for retraction in openingthe drawer. These'compartments pro vide mountings for combination locks in accordance with the invention herein, including an index member 7: provided with a knurled knob or head8. After the bolt of the lock has been'released, the compartment or drawer may be opened by a pull on the knob 8. Asthe knob v8 moves outward in Specification of Letters'-- Patent.

The upper rib. 18 terminates'in a projection '19, as is the case with the lower rib18, which retraction of the bo'ltfidmay result'frorn or cabinet 1 maybe provided Patented Sept. 14,1920.

response to such pull, the released bolt slides into the lock and does not interfere with;

. this opening of the compartment or drawer.

Accordingly the knob 8 does not have a bolt withdrawing action by direct connection to the bolt, but the movement ofthe door or drawer out of the opening forces the'bolt into the lock. -The grips or handles 6. in

opening or closing, a drawer or door, in

directly cause the bolt 20-'to be thrown.

Y A fixed scale or plate member 9 is niounted by pins 10 to provide centrally thereof a seat for the index member 7. Rearwardly from'the member 9 is the mainjlock mounting plate 11 having the central sleeve-152 forwardly projecting concentrically of the members-7, 9. This plate 11 is mounted by the screws 13 in position on thedoor' or 7 drawer front inner side. This mounting plate has a second concentric forwardly projecting sleeve 141 about the'sleeve 12, and

also an angular flange l5'having'anope'n-p I ing 16 therethrouglrcoacting with the bolt head-17fhaving'the centering guide ribs 18.

coacts with the flange 15 in limiting the outward throw of the head 17 of the bolt 20 as thrust by the yieldable means orhelicjal spring 21 surrounding said bolt and operat- 1 ing between the headl'? and sleeve'l i. The bolt 20, when forcedtoward the lock mechanism, protrudes through opening 22 in the sleeve 14. This inward travel or movement of the; drawer or door as to the cabinet, due to bevel face 23 of thebolt, head 17 sliding against latch plate OI CaSlILg. 24:

as the-drawer or door is closed.- .Also the bolt 20 maybe retracted dueto the coaction of bevel face 25 of the bolt head 17 sliding against latch plate 241 in'opening the drawer or compartment. p L1 Thebolt QOinay be looked retracted orin withdrawn position. The member or mounting plate 11 is provided with a slot-26 (Fig.

2) in which a rectangular'stem of a d o g 27 provided with aprotruding head -28 is mounted. With the bolt 20 retractedpsay upon pushing inward by hand, the dog- 27 1 may be moved to engage the upper pro jection 19 of the bolt. Thus the dogfl? is rendered inactive. However, in-l'arger work the dog 27 may be operated by one on the inside or". the compartmentto coact, with a disk or tumbler 29 out of operative engage ment with the sleeve 14 of the, mounting plate 11. This dish 29 has its bearing about the outside of the sleeve 12. This tumbler 29 has a seat or notch 30which inrthe rotation of the tumbler 29 may be brought into such registryxwith the opening 22 in the Sleeve 14 that the bolt may be retracted thereinto; On the forward-side thereof, the tumbler 29 carries the projections 31, 32, spaced from each other peripherally and 'lorated as may be expedient in determining combination relations for the lock.

' Spaced by the loose washer 33 from-the tumbler 29 is the tumbler 34 having the seat or notch 35 analogous to the notch of the tumbler 29, for when alined with the notch 30 and opening 22, this notch permits retraction of the bolt 20, as shown by the-position of the members in Fig. 5. This second or forward tumbler 34 has centrally projecting from its forward side the cylindrical portion 36, adjacent thereto the angular keying' seat 37 and the externally threaded terminus 38. From its opposite or rearward side this forward tumbler 34 has adjacent its periphery the rearwardly extending projection 39 rotatable to intercept the projections 31, 32 of therear tumbler 29 in operating the combination lock. The angularposition of the projection 39 as to the notch 35 is a'matter of selection in worlzing out the desired series of combinations. For changing-or giving the lock 'a different combination, the index member 7 as well as the scale member 9 may be shifted angularly.

A friction disk or fiber washer 42 is mounted on the cylindrical portion 36 of the tumbler 34 for clamping between the tumbler 34 and the index member 7. This clamping is yieldable. The ring 41 through its shoulder40 ten'ds through engagement with the seat 37 to preclude angular rotation of the 7 ring 41 as to the tumbler 34. Nut 43-run inserted coaxial therewith to shield the conup on threaded terminus 38 brings into action the washer 42 for a holding action sulficient for normallock operations. This nut 43 is then locked by the similar nut 44, each being operated to positionby a two prong wrench engaging the seats 45 diametrically disposed.

The index member 7 is assembled on the front tumbler 34. The spindle 46 may be necting means between the tumbler and indicator and extend through .the washer 33 and sleeve 12, for detachable and relatively rotatable mounting by the nut 47 concentricallyof the rotative elements of the look as well as concentrically of the sleeves 12, 14,

and scale member 9.

As an instance of the lock operation, it

right "to have itsindeX point on the indi cater member 7 stop at scale mark 10 or the second indicator member 9; The projection 39 of the tumbler 34 has its coaction with theprojections 31, 32 of the tumbler 29in the ,arc region having the notch 30; The projection 39 thus coacts with the projection 32 to carry the notch 39 past alining with the recess 22. In bringing the index member 7 back to 22, the projection'in this r0- tation to-the left engages the projection 31 and brings the tumbler 29 to have it's notch 30.1egister with the opening22. The third rotation of the index member 7 is now to the right from 22 to 40 to bring notch 35 in register with the opening 22 and notch 30. The drawer or door may now be opened by pulling on the'knob 8 out from the cabinet, for by this action the latch plate 24 Wet gesth'e bolt head bevel 25 to slide the bolt 20 into retracted-positionf The lock. accordingly acts permissive'of bolt throw, but does not actually throw the bolt 20.

Combination change may be simply effected without'access to the lock interior.

Vith the'bolt 20 retracted, it may be 'so held by the dog 27 as actuated by the head 28.
