1 This invention relates to improved door locks of the type in which the unlocking operation is controlled by the insertion of a coin. Locksv arrangement which entirely eliminates the usev of an outside operator. In a lock constructed according to the present invention, the more insertion of a proper coin serves to place the control mechanism in such a condition that the door may be easily opened without any additional operation. In the preferred form of the invention, th

initial opening movement of the door itself supplies the unlocking motion which would otherwise have to be separately applied through an outside operator. For this purpose, I prefer to employ a rotary type bolt capable of disengagement from its keeper to permit opening of the door only by rotation. When the door is locked,

such rotation is limited, by suitable latching means, to an amount less than that required for disengagement of the bolt and keeper. This, of course, permits slight opening movement of the door at all times, but normally that movement has no effect on the bolt latching means. After insertion of a proper coin, the control mechanism is so conditioned that the defined slight opening movement is suflicient to release the latch which previously limited rotation of the bolt and allow escape of the bolt from its keeper. The above limited movement also serves to reject any slug or improper coin having a central opening.

Desirably, I provide an operating mechanism movable at all times in response to the permitted rotationof the bolt but normally inefiective to release the bolt latch to permit opening of the door. The design may be such that an inserted coin comes to rest at a predetermined location in which its presence causes the defined permitted movement of the operating mechanism in response to slight opening of the door, to release the bolt latch and allow the door to be completely opened. 1

The present invention also includes anpeasily removable unitary control assembly which may be withdrawn from the lock housing for replacement by the release of a single retaining means.

In the preferred form, this retaining means comprises a key controlled hold down bolt, the

counter which records the number of coins deposited.

The conventional door lock of this type is 013- erable after the insertion of a single predetermined type of coin, most locks being designed to receive nickels and some to receive dimes. The present invention represents an advancement over such a device in providing a lock which may be opened after the insertion of any one of two or more types of coins. v

The above and further features and objects of the present invention will be more clearly understood from the following detailed description of the preferred embodiment illustrated by the accompanying drawings, in which:

Fig. 1 is a front elevation of the lock and keeper;

Fig. 2 is an enlarged vertical section taken on line 2-2 of Fig. 1;

Fig. 3 is an enlarged section taken on line 3-3 of Fig. 1, showing the bolt assembly, door; and inside operating knob in plan elevation;

Fig. 4 is a vertical section through the bolt housing and keeper taken on line 44 of Fig. 3;

Fig. 5 is an enlarged fragmentary vertical section taken on line 55 of Fig; 4;

Fig. 6 is an enlarged fragmentary vertical section taken on line 6-6 of Fig. 4;

Fig. '7 is an enlarged horizontal section through the bolt housing taken von'line 11 of Fig. 4;

Fig. 8 is an enlarged fragmentary vertical section taken on line 8-8 of Fig. 4, showing the mechanism in normal position; and

' Fig. 9 shows the mechanism illustrated by Fig.

8 in the displaced'position whichoccurs while the door is being opened after insertion of a coin.

Referring to Fig. 1', the invention comprises a bolt assembly, generally indicated 'at I0, and a keeper l l. The bolt assembly is borne by the door i2 whose operation is to be controlled, and the keeper is secured to the door frame I3 at a point opposite the bolt. The belt assembly is contained within a housing 14, which is divided interiorly by a partition 93, see Fig. 4, into an upper chamber it for the reception of the coin operated control-mechanismgenerally indicatediat I6,

1 and a lower chamber'or b'ox II'for 'theweceptiom and retention of coins. The lower chamber is accessible for removal of coins through opening-V I8, which is closed by key controlled door I 9. The lock requires no outside operator; butem ploys an inner knob 20 which. may. beturned to unlock the bolt and permit opening; oflthe' door irrespective of the condition of the control me'cl'ranism.

Cruciform bolt 2I is carried on-the keepers-we of housing i l for engagement with the reeessesyof the keeper and is rotatable with shaft 22 to which it is rigidly. secured. Shaft 22. bears, within the. housing, a ratchet'wheel" 23whicli isno'rmally retained against rotationi by. dog or latch I I' of thecoincontrolled mechanism It to also prevent rotationofithe shaft and bolt 2| .t When the. boltis thus. preventedlfrom rotating, the interengagementlofits then dependingvfinge'r withIlug, I215 of the keeper actsasa locklto preventopening the door. A multiple. lobed cam 25 is also carriedby. the shaft lfwithi'nthe housing; and operates theicontrolimeclianism IB'; when a suitable coin has been inserted, to; disengage. the dog from :ratchet. 2 3 in response to; slight rotation of the. shaft.v Such unlocking rotation occurs when pressure is: exerted. against. the door to slightly move it in the opening direction. The claims refer to the bolt releasing action as being. aresult of the exertion of pressure, against the bolt housing, However, thisvterminologyr is, of. course,.intended to also include aideviceiin-which the pressure acts-against thedoor.v I

The keeper I-I comprises, an angular. member attachable to thedoor frame, as by; boltsIII, andv having: two communicating recesses? 24- and I24" These recesses arerpartially separated; by lugs I25 and I26. As a depending; finger oft bolt 2|. is moved against lug I25; the latter causes-theboltto rotate out of? latched? engagement with the keeper. The: lug: I26- fulfills': no function: in the installation illustrated; but.is:providedin. order that the same'keepermaybe employed: in vertically reversed position for use with a door hinged. in the: opposite; manner in: which: case the lug I28 is used and lug I25 performsno functiom Similarly, bolt 2 I may: bei borne: on? theopposite side'of housing I4'2to permituse of aniotherwise' identical bolt 1 assembly on: an oppositelyhinged door;

Though: the bolt normally will' only operate through approximately a 90- degreeaangle', it is capable of effectiveoperation-regardless=of angular position, andconsequently cannot bytampering, be preset to any inoperativeposition; This result is achieve'diby the provisionof: a bolt presenting aplurality of: uniformly spaced projec tions.

The control mechanism-isrigidly: secured to; an upperplate 26, which serves as thertop of' hous-- ing I 4 when installed and containsacoin slot 21; a sign' viewing window 28; and: two"- circular openings' wand'" 30: Window ZB'i'sclDsedby'a transparent pane' I23; which is'retained inposition by holder I29. A key operated hold-down nut3I' isireceivableiwithin.opjening 29 and screws onto; studi 321,, projecting upwardly within; the;- housing. to: rig-idly securerthm control'imechanislm 4 in the operative position and prevent its unauthorized removal. Key operated control 32, within opening 33, is rotatable to operate the lock without a coin and to displace sign 33 from beneath window 28 for purposes which will appear later.

Essentially the control mechanism comprises a coinselector, generally indicated; at 3 1,, a cam operated bell crank 35 which causes pivotal movement of the coin selector in response to rotation of cam 25,v a pair of fingers 55 and 58 borne by shaft tie-and movable with coin selector 34 after insertion of a:=suitahle:coin, a shaft 31 rotatable by'suchifingeri movement to unlock ratchet wheel 23; and. a sign: controlling mechanism generally indicated at 3.8, rotatable on shaft 31 to control the positioningof' sign 33 beneath window 28.

Bell-crank 35 has a sleeve-like bearing portion 39 surrounding one endi of the shaft 3? about which the crank is freely pivoted. Three pairs of; spaced".arms49.,' 4]. and 421 project from sleeve 39. their extremity and serves as a at; low friction fol-- lower. for contactingvthe cam. 25. A pin Mi: ex tendsbetween.v the extremity ofiarms lz to follow the opposite side of the, lobe of cam 25 adjacent" to the lobe contacted by roller '43 and thus cause thecamto befollowed exactlyv The arms are pivotally connected at to linklifi whose other' end is connected to coin selector 3V4 by pin M;-

The coin selector may be of any conventional design suitable. for the purpose and is.- typicallyv shown as being composed of: several sections: 48}, doweledby pins 49,.and. r.etained together asbyscrews 58. The coin, selector is pivotableabout pins 51-. It. can readily be seen that rotation of cam..25from thelocked position of Fig; 5 causes upward. movement of. arms 40' and consequent" pivotingzofthe'bell crank aboutshaft 31"to move armsxl; and'link- '45-to the. leftand'thusvcause pivotal. movement of the coinselectorabout pins- 5 Shaft- 3:5: carriesr two operating sleeves 52 and 531 and two spacersleevesv I52: and.

Movement of arm 55 through the .same are changes the counter reading only one unit' be:- cause ofits initial distant position from pin I59 Aswill be seen later, arm 59- thus advances the: counter two-numbers when adime is used to open thecdoonand-arm 56 operates the counter when a nickel is used. Therefore, the counwherel-thevcoini closesithe cutaway; portion of; the:

' selector and causes any subsequent movemenizrofr:

A- roller 43' is carried between arms 40 atthe coin selector to be transmitted to the finger through the coin itself. For instance, a nickel, when inserted through slot 21, passes through opening 68 in the sign, falls into the coin selector and comes to rest in the lower portion of slot 5| opposite finger 55. Similarly, a dime falls to a position in the lower portion of slot 62 opposite finger 5B.

The lower portion of the coin selector is provided with a projection '63 having an opening 54 for the reception of coin retaining pin '65. Rotation of this pin is prevented and its longitudinal movement within the opening is limited by stop 66. Fig. '7 illustrates the normal position of pin 65 within opening 64. In that position, shoulder '61 projects into opening 62 to retain any subsequently inserted dime in a position opposite finger 58. A short guide 68 directs the coin to the forward part of slot '62 in order to assure its engagement with shoulder '61. Pin '65 bears an additional shoulder 69, which serves to retain an inserted nickel in a position opposite finger 55. It will thus be readily understood that, when the mechanism is in its normal position, a proper coin inserted through slot 21 will fall to a position at the bottom .of the coin selector where it will be retained opposite either finger 55 or 58 by one of the shoulders on pin 65. The coin itself will then transmit any pivotal movement of coin selector 34 to the adjacent finger. L-shaped wire llll extends transversely from pin 65 terminating in the end 165 which passes through a hole in the coin selector into the passageway through which nickels pass downwardly within the selector. Shifting of the pin within opening 64 also shifts wire Ifll. When the pin is in a position to allow coins to fall from the selector, the wire stops any newly inserted coin and thus prevents its passage completely through the coin selector.

Shaft 31 bears a three section operating plate 18a, 18b, and 180 extending tangentially from its surface. One end of the finger 58 operates against the central portion a of this plate to transmit the finger movement to the plate and thereby to the shaft 31. Similarly, finger 55 operates against end portion 10b. Locking dog 1| is rigidly attached to shaft 31. Spring 12 operates against plate portion 100 to normally retain the shaft 31 in a position causing engagement of dog 1! with ratchet Wheel 23. It is this engagement which prevents the door opening rotation of the shaft 22 and thus causes the door to be normally locked. However, when shaft 31 is rotated from the position of Fig. 8 to that of Fig. 9, dog 1| is disengaged from the ratchet wheel and the door may then be opened. Such rotation may result from pivotal movement of coin selector 34 when a coin 13 is in position, say opposite finger 55 to transmit that pivotal movement through the finger to plate 18b, and similarly where a different coin is positioned opposite finger 58 to transmit the movement therethrough to plate 10a.

The sign mechanism 38 controls sign 33 which has three positions indicating to the operator the internal condition of the lock. In the normal position of Fig. 8, the word Vacant is readable through window 28. Inthe displaced position of Fig. 9, opening 68 is opposite the window to allow reading of counter 14. An intermediate position causes the sign In Use to be visible. which are pivotable about shaft 31 to permit the three previously mentioned positionsof the Sign 33 is borne by a pair of spaced arms sign. A spring 16 acts as an extension of portion 10a of the operating plate to bear against projection 11 on one of the arms 15 and cause movement of the sign in response to rotation of shaft 31. Spring 16 is normally spaced from projection 11, as can be seen in Fig. 6, so that rotation of the shaft will move the sign only when that rotation is of apredetermined magnitude, If the sign is prevented from moving for any reason, spring 16 yields to allow unlocking rotation of shaft 31 while the sign remains stationary. The sign is normally urged to the Fig. 8 position by spring 118. bears an L-shaped extension 19, having a spacer at its extremity for preventing complete return of the coin selecting mechanism toitsnormal position when the sign is in other'than the Vacant position. When the signis thus displaced, the spacer 80 is positioned in the path of the coin selector to retain it in a ,position slightly removed from the normal position.

A hook BI is pivoted at 82 to one of the arms 15 and is yieldingly urged downwardly by spring 83 also borne by that arm. In the normal position, see Fig. '8, this hook rests above pin-84 projecting from the counter supporting member 85, which is rigidly attached to the frame 86I of the operating mechanism. When, however, the sign is moved to the position of Fig. 9, the hook end engages pin 84 to prevent movement of the sign back to normal position even after the pressure of spring 16 against projection 11 is released. The sign can then return only to the intermediate In Use position where it is retained until release of the hook.

In addition to the above described coin operated mechanismfor unlocking the door, a knob operated means is provided. This means includes a double armed bell crank 86, which is pivoted about shaft 31 and whose arms bear projections 81 and 88 for engaging plate portion 18a to cause unlocking rotation of shaft 31. tion 81 also engages the lower armof hook 8! to release the sign from its In Use position if the hook has previously been engaged with pin 84. The arms 89 and 90 of the bell crank 88 are connected by an operating rod 9 I. Knob 2i! bears a cam 92 which operates against rod 9|, when the knob is turned, to cause pivoting of the bell crank and through it rotation of shaft 31 to disengage dog 1| from the ratchet wheel=23.

A shifting stop 93 is rigidly carried by shaft 31 and operates to shift the position of pin 65 within opening 64 when the 7 coin selector is pivoted to cause contact of that pin with the stop. In the normal position of Fig. 8, lug 94 on stop 93 engages and shifts pin 65 after only slight movement of the coin selector. When, however, stop 93 has been rotated with shaft 31 in the unlocking direction, lug 94 is moved out of the path of pin 65, which may then move to a point of contact with the face 95 of stop 93 before shifting occurs.

To permit opening of the door by an attendant without the insertion of a coin, key operated control mechanism 32 isprovided. By use of the proper key, the attendant may rotate this con trol mechanism to move operator 96 against plate 100 and, through it, cause unlocking rotation of shaft 31. sign 33 to a position in which the counter reading is visible through window 28.

The mechanism is normally in the locked position of Fig. 8'in which the word Vacant is e b nsi n 33. through window 28 and do One of the arms 15.
