COIN-CONTROLLED .LOCKING MECHANISM.

Application :filed May 20, 1921.

To all whom t may concern:

Be it known that I, FRANK J. Rowsn, a citizen of the'United States, residing at Pawtucket, in the county of Providence and Sta-te of Rhode Island, have invented certain new and useful Improvements in Coin- Controlled Locking Mechanism, of which the following is a specification.

My invention relates to improvements in coin-controlled locking mechanism of the general typer disclosed in Letters Patent of the United States, No. 1,013,033, granted to me on vOctober 29, 1912, comprising a bolt and its keeper, a coin control for the bolt, a key control for the bolt operatively independent of the coin control, a shutter for preventing the insertion of a coin while the thing or service controlled by the lock is in use, and a counter for recording the number of coins that have operatingly passed through the coin control; the objects of my invention are to simplify the construction `and assembling of the various components, to render the counter accessible only to authorized persons, and to control the shutter by both the coin cont-rol and the .key control so that when the locking mechanism has once been worked through the agency of a coin, it cannot again be worked until after the shutter `has been reset by the attendant. lThis is particularly desirable in the case of pay toilets7 which are to be cleaned and re-supplied with toilet articles after each occupancy and before a new patron uses the apartment.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which, l

Figures 1 and 2, are front, and plan elevations respectively of my device shown mounted on a door, a fragmentary portion only of the latter being shown.

Fig. 3, is a verticalsectional elevation taken on'the line 3 3, Fig. 4.

Fig. et, is rear elevation of the main body portion of the device, showing the various elements cf the coin control mechanism in their nermal er inoperative positions.

the inner handle, independently of the coin control.

Fig. 6, is a fragmentary detail view show` ing the cam` plate 81, the liXed plate 83- and co-acting parts in their inoperative po-y ing the side platelQ- and' the shutter 25- in their inoperative position.

Fig. 10, is a detail View, of the side plate 13, showing the coin guide Strip 20- and the bolt retracting element 27- mounted thereon.

Fig. 11, is a detail View similar to Fig. 9, showing the position of the several parts at the moment of discharging the coin' therefrom. v

Fig. 12, is a detail view, showing the manner in which the coin is retained in 'the coin carrier `until proper moment of discharge therefrom.

Fig. 13, is a detail view, showing the return pawl 55, counter 3- and the several tension springs employed.

Fig; 111, is a detail view, showing the manner of releasing and resetting the shutter by use of the attendants key.

Similar characters refer to similar parts throughoutthe several views. For conciseness and clarity of expression the following terminology will be. employed. The subject of the invention will be termed a coin lock. Placed coin will define the proper coin for working the coin control, seated in operativeposition in the coin carrier. Coin control will define the group of mechanism by which retraction of the bolt is secured through reaction of a placed coin. vCoin carrier will define the composite member in' which the placed coin is seated for the pur pose of reacting uponthe bolt and coordinatedparts. Coin width expresses a width between .elements substantially identical with the coin diameter but permittingl free movement of the coin. The shutter for thek coin slot will be described as closed when covering the coin slot, and open when uncovering the coin slot. Key control will define the device whereby the lock bolt is retracted by use of a key independently of the coin control, to admit an attendant or other author-ined person. lVasher means auf.v spurious article inserted to work the lock in lieu of a coin such as a washer, having a central opening.

Referring to Figures 1, 2 and 3, my coin lock comprises, in a` case 1, the bolt 2, the key control and the coin control, the counter 3 for recording the number of coins deposited, and the various connections which coordinate these associated groups in one unitarlvv mechanism. The lower portion of the case is a depository for coins to which access is provided by any suitable means. rlhe operating spindle or shaft et projects through the front of the case, carrying the entrance handle In the front of the case are a coin slot G through which the coin is placed in the coin control, and the seutcheon 7 of the key control, by which the attendant operates the coin lock inde pendently of the coin control. rl'he case 1 is open at the back and is formed to tit over a back plate 8 which is secured to the door to be locked. Through the door and back plate a spindle 9 extends7 to one end. of which the exit handle l0 is secured, and on the other end of which there is the disk 11 having the function of operating the lock bolt 2 from the exit handle. Turning' the exit handle presses the projection 8() of the disk 11 against the lug 8l of the bolt Q, re tracting the latter.

Upon the shaft l 9) there is secured a plate 12, being' one of the two side plates of the coin carrier. The other plate 13 secured to the plate 1") by two spacing posts 1l and 15, which maintain the plates at a tixeil distance apart. The two plates 12 and 123 are so formed and related as to provide a coin seat. In the lower portion of. the plate l2 a channel is cut, rectangular of form and of a width corresponding to coin thickness. The wall 1G of the channel, corresponds and alines with the edge 17 of the plate 12 and serves to support and guide the coin. The wall 18 constitutes a retaining ledge which engages the placed coin with restraining effect. The coin seat or stop is formed on thc plate 13- preferably by the attached strip 20- whose upper edge Q1* supports and guides the coin, as do the edges 16 and 17 of the plate l2. A shoulder 2Q- on the strip 20- forms the coin stop or seat by reducing the space between plates 12 and 17% to a distance less than the diameter of the operating coin` and by projectingr into the path ot and contacting` said operatingr .coin` ,ali :i point just below the horizontal center. thereof. The portion Ql of the plate 13E is bent inward toward the plate 12. to constitute a retaining ledge corresponding to the retaining" ledge 1S. hul dili'ering in that it is inclined to the face ol' the plate 123 and lo the 'tace of the coin. lVhen a coin is inz-serled in the coin .slot t. it is guided by a guard 2l into the space between the plate lb and the shutter 2) which lies close to the plate 12 and between the plate 12 and the front of the case. rl`he coin slides down the edge 1i' of the plate l2 and the top 21 ol the ledge or strip 2() into the coin seat where it is stopped hy thc shoulder ln its way from the coin slot to the coin seat, the coin passes under the linger 2G of the element. E?, which linger acts to guide the coin.

',lhe element 2T is mounted on the plate lil, swinging on a suitable stud or bearing. The portion to the opposite side of the stud is provided or formed with two projectures1 one illu extending inwardly toward the interior of the coin carrier; the other 2l) extending outwardly into a plane where it. will if properly guided, engage the bolt :l by the angular projection 30.

'lfo control the element 2, a cam plate lll if; mounted on the shaft .l, next adjacent the side plate 12 of the coin carrier. and free onV the shalt so that movement o l' the .shaft will not cause movement ot the cam plate. except through the reaction oi a placed coin as will he explained. On the cam plate, near the shaft, fl. is a projection 23:5 which extends away from the plate l2. and sul`- ticiently to extend suhstantiallli.' beyond a lined plate llzl next adjacent the cam plate. rl`he plate -l is fixed with relation to the coin carrier and the shaft being mounted on the spacing posts` 1l and 15 which hare shoulders on which the plate is seated. Separating collars between the side plate 13% and lixed plate hohl the latter to the slloulders'of the posts. In the plate il?) Iis a clearance openinglo permit oscillation of the plate 333 without contact with the cam plate projection i2 which extends through and beyond the plate ll. Mounted on the plate 33 is a coin presser lever i-lpivotcd at its workingarm resting on the projection $32 of the cam plate. This engagement maintained by a spring Bti mounted on the spacing post 1l with one arm pressing on a projection ET of the lever Illand the other arm. hooked al h. en; ing n link 3l) (Fig. (3 and Fig. which in turn engages a hooked or equivalent toi-mation all on the element The working end ot the coin iiresscr leiter is' cut awa \Y lcaring a projection ll against which a placed coin hears. rcactinq against. the lever to pressl the la rer upon thc cam plate proieelion llt? lo lern .the

llU

canil plate with the coin carrier and with its sha'ft.

The coin is retained in its seat in theA coin carrier to secure such reaction by a slide 42, the extremity oit which works lin a channel cut transversely of the coin `channel. inthe pla'te l12 and entering it. The

width of coin seat as formed in the coin carrier, which is to say, the distance Tbetween thebot'toni 43 "of the coin channel in the plate 12 12) and the plate 13 exceeds coin width; also, the distance trom the channel bottom 43 in the plate 12 to the nearest portion of the inclined ledge 23`like- Uwise 'exceeds coin width. The distance between the retaining ledges 18 and23 is less than coin width, so that a coin cannot escape them` unless 1t has sutlicient lateral movej ment to first escape one or" the ledges. The

" slide 42 between the bottom 43 of the coin 0n the saine post is'mounted the bell `crank lever Ll'one arm ot which engages the slide while the other arm extends outward,

impelled by the spring ;r44', beyond the plate 12 which carries it.v On 'the case 1 isa projection 46, so located asto encounter the lever. 4:7 when moved suliiciently by oscillation ot' the coin carrier. Continued movement of the coin carrier after the lever 45 has encountered the projection 46 causes movement of the lever on the p'late .12 and with it, withdrawal of the slide 42 from between the coin edge and the bottom 43 ot theA coin channel. Pressed outward from the/,coin seat by the projection 41 on the coin presser lever 34, the opposite portion ot "the coin edge is forced against the inclined retaining `ledge 23 shitting the coin laterally in the widenedcoin seat until the coin isforced past the retaining ledge and ejected. (Fig. 9an'd Fig. 11.) y

In case a washer were inserted in lien of a coin, the projection 41 would enter 'the hole ot' the washer'. As `the coin carrier is tlnned, there willfb'e no pressure ofthe coin presser lever 34 on thecam plate projection 32,; hence the vcam plate is not turned with the ensuing actuation described, but the washer is ejected `by the following described action'. 'The coin pressure lever 34 has a `.earn `face 47. Betweenthis projection and the working tace 47a o't' the saine member 34, which rests upon the cani' plate projection 32 is an indentation or clearance. As the coin carrier is turned,

the projection 32 enters this indentationpressed' surfaces 48 and 49 encounter the washer and eject it upon its release 'from the coin carrier through withdrawal of the slide 42, just as 1n the case of a goodcoin.

The cam plate 31 has a cam edge 50 upon" which the projection 23 of the member 27 usually rests. It, under coin control, the coin carrier and cain plate turn together, the projection 23 remains on the cam edge 59, and the projection 29 remains in position to engage the bolt 2 by its angular pro'- jection 30 (Fig. G). In case there is no coin placed in the carrier when the latter is turned", then the cam plate remains stationary, held by a spring 51 acting througha link 52 anchoredto a projection 53 of the cam plate; the projection 28, impel'led by the spring 36, through the link 39, acting on the element 27, follows the cam edge 50, depressing' the projection 29 so it cannot the bolt 2, as shown by broken-lines in Fig. 7.

Both the coin carrier and the cam plate are restrainedby a pawl troni returning to initial position after having been coin operated, until after the inside or exit handle '9 has been worked. ployed for this purpose, and the `relation ot those means to the present inventionare so closely counterpart of what is disclosed in1 my U. S. Patent No. 1,043,033, as to require noI further description here.

The link 52, through which the `spring 51 returns the ycam plate 31 to initial position extends below the point of spring engagement to the working arm 56 of the counter 3. .'lherefore, whenever the cam plate 31 is coin operated, the counter records the event.

` The key control is a suitable lock, prete'rably ot' cylinder type equipped with anv arm 57 to retract the bolt 2 by engagement with the shoulder 58, and a cam lug 59to control the opening of the shutter 25. T he latter swings on a stud or bearing 6() and has a slot or opening 61 normally registering` with the coin slot '6 in the case. The edge of the shutter next to the coin carrier is formed at 62 as a cam, with which a follower 'ri engages to move theshutter. At 64, the cam edge of the shutter is cleared away so that when 'the shliitter has been moved-'its prescribed distance to close ity The means erufurther movement of the follower may be permitted, without any consequent movement of the shutter.

The follower G3 is a pin or roll-connected with the cam plate 31 by an arm G5. rllhe side plate 12 of the coin carrier is made with in opening GG preferably of arcuate form, through which opening the follower 63 extends from the arm G5 to the cam edge G2.

Attached to the shutter is a latch G7 having a catch formation G8, a release portion G9 and a lug 70. A fixed detent projection 71 is established in any suitable way, near the catch portion of the latch and near the cam lug of the key control. The detent is here shown as part of the casing of the key control7 secured thereby to the lock case 1. wWhen the shutter 25 is open the release portion 69 of the shutter lies against the cam lug of the key control, with the catch 68 disengaged from the detent 71. The latch is movable on a pin or fulcrum 7 2 and a spring 73 suitably anchored bears upon the lug acting with dual effect, to hold the latch toward the datent 71 and the cam lug 5S), and also to hold the shutter open. lVhen the shutter is closed by action of the cam plate 31 through the follower G3, the catch 68- engages the detent 71, land the release portion G9 is projected into the path of oscillation of the cam lug 59 as will be seen by reference to Fig. .11. lVhen the key control is operated to retract the bolt 2 through action thereon by the arm 57, the latch ('37 is depressed by the cam lug 50 and the latch spring 7 3 opens the shutter 25.

@verhanging the top of the shutter is the coin guard 241 previously referred to. This is formed with a supporting edge 7 fl which receives the coin when it is inserted through the slots G and (31, preventing the coin from leaving its proper course, and directing it upon the supporting edges 17 and 21 of the coin carrier. Opposite the coin slots, the guard is formed as a hook with an inclined hooking edge 75, to receive the coin should it be tilted in entering the coin slot, and further guide it to its proper position and course.

The operation of my coin lock is as follows. A coin is placed by insertion through the slot (S of the case. It passes the opening G1 of the shutter Q5 and encounters the guard 2l by which it is directed in its proper course to the coin seat in the coin carrier, passes en route under the guiding finger Q6. Entering the coin seat of the carrier, the coin inter-poses itself between the slide l2 and the plate 13, being stopped at and held in the right position by the shoulder Q2 on the plate 13. Turning of the coin carrier by the entrance handle 5 presses the coin, which is held to its seat by the retaining ledges 18 and 23, against the projection 41 of the coin presser lever 3l, thereby acting upon the cam plate projection 32 to turn the cam plate. The cam plate in turning maintains the element Q7 in position for its projection QS to encounter and work the bolt, and it also engages the follower (S3 with the shutter to close it. T he shutter in closing is locked shut by the latch 67 as explained.

Continued turning of' the coin carrier brings the lever 4.5 in contact with the obstruction 40 turning the lever 45 on its fulcrum and withdrawing the slide 42, leaving the coin free to shift which it does under reaction of the inclined ledge 23 to pressure of the cam plate return spring 51 transmitted through the coin presser lever 31. Having moved laterally a sufficient distance to free itself of the inclined ledge 23, the coin is released and is ejected by the coin presser lever 3st. The cam plate being now released from the coin carrier, returns under' impulse of its return spring until restrained by the pawl In return ing the cam edge 50 recedes from the projection QS permitting it to follow the cam edge 5l, when otherwise free to do so. But, as in the coin lock of my U. S. Patent 1,013,033, the projection 2S is trapped by the angular projection 30 of the bolt 2 so that until the bolt is retracted independently of the coin control, as by its keeper in closing the door. the bolt can be retracted any number of times by working the handle lVhen the projection 9,8 is thus released it falls between the cam plate 31 and the fixed plate 33 upon the cam edge This raises the coin guide or the finger 2G throwing the coin channel wide open and permitting any contraband material to drop out.

In the case of a pay toilet, the customer .ses the exit handle 9 to open the door, working the bolt independently of the coin control through the disk 11, which also encounters the pawl withdrawing it from the coin control and permitting the latter to return to initial position to be coin operated as described in my U. S. Patent 1,043,033, excepting, that the shutter is not opened to permit insertion of a coin. Before the toilet can be used by another custoiner it is to be cleaned by the attendant, who in order to gain access uses his key to open, the door. rlhe action of, the key also serves to release and permit the shutter 2.5- to return to its initial position with the coin slot open.
