Be it--known that I,- WILLIS'- FAn'nsi wonrn, citizen of the United States, residing at Petaluma, inthe county of Sonoma and State of California, have invented new and useful Improvements in ACoinf Controlled Locks, of which the: following is a specification. i l.
Thisinvention relates, to vcoin Controlled locks and particularly Vpertains to a device for controlling' the operationof a lock byl means of coins, slugs or other tokens.
It is the object of this invention' to provide `a ooinoperate'd mechanism for controlling locks, by means of which the lockfcan .be op`- erated only-by the depositing of a proper anism is prevented 'from .becoming blocked through-:the depositing o f more than one coin and which can beoperated only by a coin of a. certain diameter.

cloak rooms, and-other places where c, mimber of safe-deposit boxesand the like are installed and where each separate Vdoor is provided-with a special lock and key. l
yThis device is so `designed that the key cannot be removed from 'itsrespectivelok until a certain coin has'bcen deposited,'nor a lock unlocked wit-hout. the previous dropping of a coin, but when ythe required com is deposlted, the customer or user ymay unlock or relock the desired door and rcmovsthe key for opening the door at a future time.V It
is also so constructed that the locker can be used but once for a single coin.
In the drawings A represents a door which may be hinged and framed in any-.desired manner. B is the barrel of a cylinder lock of any'suitable type mounted in a cylinder casingl C and haif'ing thel usual loose pins 2, which are actuated by the insertion of a key 3 in the. keyhole l extending longitudinally' through the barrel B. A bit or projecting pin 5 is suitablyattached to the inner 'end-ot" the barrel B and is adapted to work in a recess in one side ot a' latch bolt -64 antlvretract) thelatch bolt within'the casing-7 when the-f barrel is rotated properl v as shownintigf 3. The latch bolt'G is" normally projected into its outermost `position by means of a spring 8,v which offers `a ,resistancegto any backward movement of the latch bolt.A ff.
My.l attachment comprises ya. crank 9 clamped to th barrel B and towhich a sliding and rocka le rodA 10 is pivotally, connected. This rod 10 extends at right angles to .the barrel B through. a slotZ inthe casing 7 .and is notched atgllfon itsnnderfside toinorma-lly engagethefcasing when the bolt is in forwarded lockingfpositio'n, thereby preventing the tn'rning of the barrelB whilethusengagedl 12 is a'lateralprojectionformed on the outer "end 'o'f the rod 10, which projects linto an irregular slot 13 stamped in the short arm of aflever, 14. The lever 14 is pivotally suspivotal point 15 and bears against alstopl8.
` The outer endof the leverl 1l projects;finto a downwardly' extending lranchfllfof. a
' and 'the perpendicular branoh 19 leads t0- any suitable till, receptacle or other device for the collection of coins.
'is removed, as at 21, leading into the coin- Way 19 directly above the outer end of the Y lever 14. Interposed across this -'opening 21 g lever 14.` The .weight of the coi-n. strikingf .11" n 1;..11ntil the outer end rests on a stop '26, as' Sgshown inifull lines in Fig. 2. In'this posi-1` is a trap lever 22, which is pivoted at 23 and counterweight'ed at 24, the upper ,edge of the lever bein on a plane with and in continuation of t e bottom of the chute 19. The
purpose of ,this` weighted `trap lever 22is to. allow only a com or token of proper character and weight toI fall onto the lever 14 and `trip lever 10, so the lock canl'be opened,
- all as will be described shortly.
The operation of the invention is as follows E-Assume the parts to be in the normal position shown in Fi 1 with the key 3 in the .cylinderB and Vt e door A closed and' locked by the latch 6. In this positionit Willbe seen that the door A cannot be opened or the lock unlocked by reason of the notch- 11 in the lever 10 being engaged in theV casing 7Which prevents the necessary turning of the cylinder B to ldraw the latch bolt 6.
Neither can the key 3 be withdrawn from the cylinder :B, by reason of the latter being slightly turned to one side when the lever 1() is 'in engagement, In this position the `loose pins 2 'are not in alinement with the pins (not shown in the cylinder C, but bear 'against the wa s inside the cylinder, as shown in Fig. 4, thus blocking the key 3 against removal. '(It is understood that withlocks ofthe Yale type a key canl only Abe withdraw-n when the keyhole and key stand ina certain position, usually vertical.)
It being desired to unlock the door A and remove the key 3, al coin of the proper value, for instance,a ve cent piece, i's inserted in ,the slot 20. This coin, 1traveling down the I,inclined chute 19. rolls upon the trap lever 50V 22 and at lthis point is brought into contact with a stop' 25" interposed near the top of the vchute 19 over opening 21. Th'e stop 25' arrests the forward movement of thev coin and causes its entire weight to rest on the outer end of the trap' lever l22,which acts to rock the latter on its pivot 23, allowing the y coin to dropv through thel opening 2l into the coinway19" and u 'on' the outer-endofthe the lever causesit to rock on its pivot 15,
Aportion` of thel bottom of the chute the arrow, Fig. 2, solas to dilaw the latch (-'into the casing 7 and unlock'the do0r-.A, and perniit of its being'open'ed.v On turiiing the cylinder B as 'just described, the swinging lever 14 is-drawn forward bythe pin 12 I so as to throw the `keyhole 4 into a vertical bey-rotated by the key 3 in -the direction of o nthe lever 10, so that the coin 27 will partially drop between the semi-'crescent shaped' position position which permits ofthe'removal of the key, 'as is well khownin cylinder lock con' struction. In turning'the barrelB back to is caused to 'move-back a sulicient' distance to cause the 'pin 12 thereon to travel'back and upward the cam slot y13 until it drop's'behind a' shoulder 13 jin the cani slot 13 ofthe lever,14,."where trelnains until the key 3 is again inserted and the barrel B t rned to re-'open the door A. This causes he link 10 to draw the-swinging lever -14 forwarda second step to' release the coin 27, which drops from its -grip between the curved end 14 of lever 14' and the opposite wallof the chute into any suitable receptacle; the posiltion of the parts nowA being as shown in Fig. 3. On releasing the key 3, y the swinging 'lever 14.swings back into its normal position, in Fig. 1', thev weighted end '0j the lever .droppingdown'to' cause'the pin 12 -on the b ar 10. to become disengaged from the-notchland this last position to relock the door, the ilever ireturn to its original'positionI in'thefendof the slot1'3. 1 L -N A glazed-opening 28 is formediI'i-the. door 'A directly over the` point where the coin 27 `is sustained by the'lever 14,- so as to enable the detection ofthe presenceof a token or -slug in the chute 19" and v show- Whether the device is already in use. If i pennies, dimes orother tokens Vsmallerthan a five cent piece 'are used, they' will pass under the'stop`25 and by reason of the velocity gained by rolling down the chute..19;.w`ill In that event, whenthe lever 14,is wit/hdrawnfrom under the coin 27, thecoin on 'downtthe *chute 19, the rapidlyqmoving,
