COIN -CONTR.OLLED LOCK.

Specification of Letters Patent.

Patented Feb. 13, 1917.

Application filed March 27, 1916. Serial No. 86,901.

To all whom it may concern:

Be it known that I, ALBERT F. LESLER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Coin-Controlled Look, of which the following is a full, clear, and exact description.

This invention relates to looks and particularly to an improved coin controlled lock and has for an object the provision of an arrangement whereby the lock may be opened once from one side upon the insertion of a coin and also opened once from the opposite side by reason of that same coin.

Another object in view is to provide an improved arrangement of lock which is coin-controlled and which is also key-controlled, the arrangement being associated with counters so as to indicate the number of times the lock has been operated by a coin and the number of times the lock has been operated by the key.

A still further object in view is the provision of an improved lock especially adapted for pay toilets, whereby the door may be unlocked on the insertion of a coin, again locked when the door is closed and unlocked once from the interior for opening the door.

A still further object in view is to provide a coin controlled lock which, upon the insertion of a coin, may partially unlock and then. a pull will completely unlock the mechanism so that the door to which the lock is secured may be opened whereby one unlocking is insured for the insertion of each coin.

In the accompanying drawings Figure l is a top plan view of a look embodying the invention, the same being shown applied.

Fig. 2 is a longitudinal vertical section through a lock embodying the invention, the same being taken approximately on line 2-2 of Fig. 1.

Fig. 3 is a section through Fig. 2 approximately on line 38.

Fig. l is a view similar to Fig. 3 but with the parts turned to an operative position for withdrawing or retracting the bolt.

Fig. 1 is a rear plan view of a coin wheel embodying certain features of the invention.

Fig. 15 is an edge view of a lock showing the dials or faces of the counting mechanism embodying certain features of the invention.

In constructing a lock embodying the invention it is aimed to provide a good looking mechanism and in addition a simple eiiective coin controlled mechanism together with a number of operating parts adapted to be actuated by a key. The lock is especially intended for use on the doors of pay toilets and is intended to register each time the door is opened whether by a person depositing a coin or by a person operating the key mechanism. In addition, the mechanism is formed so that the interior knob will operate the bolt for retracting the same once upon the insertion of a coin but will not operate the bolt when the lock is opened by a key, so that a. person using the toilet and using the key must leave the door open. This arrangement also prevents a second party using the toilet without paying as he would look himself in. To insure the proper action of the bolt and to insure against operating the look without opening the door, the mechanism is so constructed and arranged that when the outside knob is operated after the deposit of the coin the bolt will be retracted for part of its length and then will remain stationary regardless of how the CID knob may be turned, but will be retracted completely upon pulling the knob for opening the door. In this way no one ever loses his coin as the knob merely retracts the bolt a certain distance and then is freed from the bolt so that all that is necessary to do is to pull the door open. lhe same arrangement is provided on the interior and when the interior knob has been operated once it frees itself from the bolt and all that it is necessary to do is to push the door open. In case the occupant attempts to operate the knob a second time, this may be done but will not accomplish any result.

Referring to the acco ipanying drawings by numerals, 1 indicates a door of any desired kind to which the lock 2 is secured, said lock being arranged exteriorly oi the door so that a coin may be placed in the coin slot 3 at any time. As shown in Fig. 1, the toilet to the door of which the lock 2 has been applied is vacant. Upon the insertion of a coin in slot 3 and then turning of the knob 1 the bolt 5 will be retracted until the point 6 will be substantially in line with the edge 7 of the casing of lock 2. The knob 1 cannot move the bolt in this position but if the knob is pulled outwardly and the door 1 opened the beveled or inclined part 8 will strike the socket member 9 and force the bolt in against the action of a spring hereinafter fully described. As soon as the door has been completely opened, or, rather, as soon as the bolt 5 has passed the socket member 9, it will spring back to a full opened position and as door 1 is open by this time, this will have no effect. The person putting the coin in slot 3 will then enter the toilet and grasp knob 10 and pull upon the same until the door is closed, the bolt 5 striking on the inclined portion 11 against the socket member 9 in order to be retracted. The bolt in this manner snaps into a locked position in the usual manner of bolts now in common use. After this has taken place knob 1 cannot again retract the bolt without the insertion of another coin. However, knob 10 may retract the bolt once, as hereinafter fully described, so that the occupant may pass out whenever he desires.

The operating parts are shown in their assembled condition in Fig. 3 as they would appear ii": the inner plate 12 of the casing 13 was removed, the section being taken approximately on line 3 3 01' Fig. 2. is shown in this figure (Fig. 3) the bolt 5 passes through a suitable opening in the edge plate 14: of casing 13 and guided thereby and by the pin 15, which pin is rigidly secured to the casing by being screwed therein. A spring 16 is connected with the casing and with the end of bolt so as to normally hold the bolt in an outer position and to move the same to said position when released. Bolt 5 is provided with a hook 17, which hook is spaced an appreciable distance from what may be termed the body 18 of the bolt, said body being biturcated at the rear for accommodating pin 15. One of the bifurcations of body 18 is provided with a projection 19 having a notch 20 arranged therein, said notch accommodating the projection 21 of a pivotally mounted member 22 held normally in a given position by a spring 523.

WVhen the bolt 5 is moved until the point 6 has reached the edge 7 of the casing, as shown in Fig. 1, the projection :21 will be in operative position and will hold the bolt against being projected by the spring 16. Upon the pulling of knob at the bolt will be forced inwardly against the action ojt spring 16 until the door can be opened and also until catch or projection 21 has moved out of the notch 20, thus allowing the bolt to be again projected to its full outer position. As clearly shown in Fig. 1, the pivotally mounted member 2:2 is so arranged that the bolt cannot return from the position shown in Fig. 1 until it has been fully retracted, and then will freely pass the projection 21 without accomplishing any results, said projection merely moving out of the way. A coin chute 2 1 is rigidly secured to the bolt and is arranged to guide the coin to a coin receptacle 25, which coin receptacle may be of any desired kind and which is preferably provided with a look so that the person applying and removing the receptacle cannot examine the contents. In order to apply or remove the receptacle the lock 26 is operated, which look may be of any kind and which normally locks the door 2'? closed.

lVhenever it is desired to withdraw or retract bolt 5 through the use of a coin, the coin is dropped into slot 3 and will pass from thence downwardly into the coin wheel 28. It the word Vacant is disclosed through the opening 29 in the casing 13 the coin will be forced in position and after the word Engaged is disclosed the section 30 of slide 31 will cover slot 3 so that a coin cannot be inserted. After the coin has been inserted the same drops into the wheel 28, as shown in Fig. 3, and lodges against pin 32 and wall'33, said wall and pin being arranged to hold the coin so that the upper part will be flush with or above the periphery of the wheel in order that the coin may engage the pin 34 and raise the same so that the pin will not lodge in the recess 35. Normally the pin 34 is lodged in the recess 36 and if there is no coin in the coin wheel the movement of the coin wheel is limited by the pin 3 1 striking the bottom of the sockets and 36, such movement of wheel 28 not accomplishing any results. Pin 31 is rigidly secured to an arm 37 pivotally mounted at 38 to the casing and is held in proper position and caused to press against the coin wheel by a spring 39. After the coin has been inserted as shown in Fig. 3, the knob 4 is turned and coin wheel 28 is turned therewith until the parts assume the position shown in Fig. 4, whereupon the coin will drop out of the coin wheel into the guide 24 and from thence it will pass by gravity through slot 40 into the coin box or receptacle 25. As the coin wheel 28 rotates the same carries with it the pivotally mounted U-shaped member 43 which is pivoted at 44 on the Wheel, the pivotal member 45 extending through the wheel and having rigidly secured thereto on the opposite side an arm or lever 46, as shown more particularly in Fig. 7. The U-shaped member 43 is provided with projections 47 and 48 with a socket 49 arranged therebetween. Socket 49 is intended to receive the pin 56 extending from the lever 57 connected with the counting mechanism 58, which counting mechanism may be of any desired kind.

When the wheel 28 moves it carries with it the U-shaped member 43 and the extension 48 strikes pin 56 and consequently moves the lever 57 and causes the counting mechanism to be operated for indicating that the lock has been operated once through the use of a key. The U-shaped member 43 is provided with a pin 53 extending into slot 54 of the wheel 28, said pin striking the coin and assisting in ejecting the same. If the coin is not of the proper size, as for instance, if it is too large, the coin will not enter in between the walls 32 and 33.- If the coin is too small it will enter and pass these walls and, in fact, pass entirely through the wheel 28, as the space between the walls 32 and 33 merges into a coin passageway 55. WVhen a key is used the U-shaped member 43 is maintained in the position shown in Fig. 3 even when turned as shown in Fig, 8 and hereinafter fully described, the holding of the parts in this position causing the U-shaped member to actuate pin 56 connected with lever 57 WVhen the wheel 28 first moves after a coin of the proper size has been inserted, the lug or extension 59 strikes the extension 60 of the plate 31 and slides the plate over to the position shown in Fig. 4. When the wheel moves back to its former position the lug 59 strikes pin 50 and moves it back to its original position unless the same has automatically moved back upon the action of spring 61. A coin of the proper size is limited in its movement between the walls 32 and 33 by a pin 32 projecting a short distance into the space between these walls so that the periphery of the coin will be in line with or above the periphery of the wheel 28. When the wheel 28 has been turned after the coin has been deposited therein the coin will strike pin 34 and raise the same so that the notch 35 may pass the pin 34 and the wheel rotate for a sufiicient distance for causing the lug 50 to strike pin 50 and move said pin together with arm 51 a sufficient distance for causing the mechanism of the counter 52 to operate once, the slot 54 allowing the pin 53 of the U-shaped member 43 to slide and thereby not affect pin 50. If there is no coin inserted the wheel 28 will not rotate sufficient for the projection 50 to strike pin 50 and therefore the counting mechanism 52 cannot be operated. However, as above described, when a key is inserted the wheel 28 is moved so that pin 34 will engage the socket 35 and at the same time the U-shaped member 43 will be rigidly held substantially in the position shown in Fig. 3 with respect to the wheel 28 so that when the wheel 28 is turned the projection 48 will strike the pin 56 as heretofore described for operating the counting mechanism 58.

The wheel 28 is provided with a stub shaft 41 on one side and with what may be termed a boss 42 on the opposite side, said boss being provided with a slot 62 into which projects the lugs 63 and G4, which lugs are extensions of the tubular shaft 65 (Fig. 12) connected with the knob 4, the connection between the shaft 65 and knob 4 being by suitable friction plates 66 and 67 of well known type the particular construction forming no part of the invention, the connection in this way being merely for the purpose of allowing the knob to turn when a considerable pressure has been brought to bear thereon and when the shaft 65 is locked. Shaft 65 is provided with a slot 68 for accommodating the bifurcated plate 69 (Fig. 5) whereby the shaft is locked in the casing 13. Shaft 65 is hollow and accommodates a pin 70, which pin is provided with notches 71, which notches are designed to receive theend of a key 72 passed through akey slot 73 in the shaft 65 so-that the pnrmay be rotated by the key. The pin is rigidly connected with a lever 74, which lever is provided with cutaway portions 7 5 and 76 in which the lugs (33 and 64 move whereby there will be a lost motion, as these cutaway portions are of greater length than the lugs. This lost motion between the parts permits the key to operate lever 74 for retracting the bolt without operating the coin wheel 28 and the counting mecha nism 52. However, the shaft 65 when actuated by the knob will rotate the coin wheel 28 and if the pin 34 is caused to move out of the way by a coin the wheel together with lever 74 will be rotated a certain distance for causing said lever to strike against the lug 77. By a continued movement of the knob 4 the lever 74 will retract the bolt 5 until the notch 20 has reached the projec tion 21.

The knob and associated parts are operated against the action of spring 39, which spring is connected to the arm 37 and to the projection 80 extending from the plate 69 so that the knob and associated parts will be returned to.their former position when released. After the bolt has been moved to the retracted position mentioned, that is, to the position shown in Fig. 8, a pull on the knob will cause the door to open and in opening to retract the bolt to its extreme position and then release the same so that it will be projected outwardly by the spring 16. In order to withdraw or retract the bolt by the knob after a coin of the proper size has been inserted, it is necessary to move the wheel :28 farther than when a key has been used by reason of the cutaway portions 75 and 76 on the lever 74;. It will be observed that lever 7% is provided with an upstanding member 81 which is adapted to engage the turned-up end 82 of the arm as for holding the arm against a swinging movement when a key is inserted, thus holding the U-shaped member 43 in its lowered or outer position as shown in Figs. 3 and 8.

When a key is used the same is inserted as shown in Fig. 2 until the kev has engaged the notches 71 of pin 7 0 so that upon turning of the key the pin will be turned and the parts connected thereto. The lever 74: is rigidly secured to pin 7 0 and consequently turns therewith, and by reason of the cutaway portions and 76 this lever will turn for an appreciable distance before turning wheel 28 and will then, upon a complete movement, turn the wheel 28 so that the pin 34.- will be in socket 35 approximately at the time the bolt has been retracted to the position shown in Fig. 1-. In this way the wheel :28 is not turned sufficiently for operating the counter 52 but is operated sufficiently for causing the rojection d8 to operate counter 58, which counter indicates the number of times the bolt has been retracted by the ke It will be observed that the wheel 28 when operated by a key is not rotated sufficiently for causing the projection 59 to move slide 31 and also does not operate to release the parts shown more particularlv in Figs. 9 and 10 so that the inner knob cannot be actuated after the lock has been operated by a key. This necessitates the occupant leaving the door open unless he will lock himself in. As shown in these two Figs. (9 and 10), when the projection or lug 59 engages the extension 60 of plate 31 and moves the plate to the position shown in Figs. 4, 9 and 10 the extension 60 will also engage the upper end of lever 83 and move the lever from the position shown in full lines in Fig. 9 to the position shown in dotted lines in said figure, thus causing the pin 8 1 to strike the inclined surface 85 of the pivotally mounted bar 86 and raise the same so that the projection or catch 87 will move out of the notch 88 in the arm 89, which arm is rigidly secured to a shaft 90 which shaft extends through the inner or back plate of the casing and has the inner knob 10 connected thereto. The operation of the mechanism by a coin will cause the disengagement of the bar 86, which disengagement is maintained until the occupant turns the inner knob 10 and partially rotates the arm 89, said movement being sufficient to cause the pin 91 to strike the hook 17 forming part of the bolt and re tract the bolt until the line or edge 6 is in alinement with the edge 7 as indicated in Fig. 1. A push upon the door will then be sufficient to complete the unlocking and opening of the door as heretofore fully described. The knob 10 under the action of spring 91' (Fig. 2) will automatically re turn to its former position and will move the arm 89 back to its former position so that the catch or lug 87 will snap into notch 88 and thus lock the parts against operation until another coin has been deposited and knob i rotated.

In addition to the spring 91 moving the knob and associated parts back to their former position it also holds the knob 10 in an outer position so that the pin 92 extending through the slot 93 of the shaft 90 cannot rotate said shaft until the knob together with its stem which carries pin 92, has been moved inwardly sufficient to cause the projecting end 951 to move out of the notch 95 in the hub portion 96 of plate 97, said plate being secured to the usual trinnning member 98 in which the shaft of the knob 10 is mounted, said trimming member being connected to the door 1 in any suitable manner, as for instance, by screws. The slot 93 of shaft 90 is provided so that the shaft 90 maybe made of some considerable length in order that the lock may be readily applied to doors of different thickness and the pin 99. operate at any point in the slot. It will be noted that after a coin has been inserted it is necessary merely to turn the outer knob and then pull the same in order to open the door, while to open the door from the inside it is necessary to push the knob inwardly and then turn the same in order to retract the bolt. Both knobs 1 and 10 are made identical in construction and are intended to rotate in case the same are forced, said rotation merely causing the outer part to slip. In case the mechanism has been released either by a key or by a coin the knob will then operate the parts as described.

In arranging a lock in position 011 a door the same may be mounted in any suitable way, but the back plate of the casing is preferably provided with apertures 99 for receiving screws or other fastening means and the large openings 100 through which the heads of screws may be inserted and then the back moved downwardly until the body of the screw engages the reduced openings 101 merging into the openings 100. This is very desirable as it is necessary or at least preferable to secure the lock near the top and near the bottom. Near the top of the casing the various operating parts of the mechanism are mounted and it would be more or less difficult to place ordinary screws therein, whereas this construction will allow the easy placing of the retaining means in position and the back plate thereon. In order to compensate for any slight unevenness of the parts and the aperture through which the shaft 90 passes, said shaft is loosely connected to the tubular member 102 by a pin 103, said tubular member being rigidly se cured to the arm 89 so that the arm is rotated whenever shaft 90 is rotated. In connection with arm 89 a retractile or return pin 104 is provided, as shown in Fig. 10, for moving the lever 83 back to its former position when arm 80 has been actuated so that when arm 89 moves back to its former orig nal position the catch 89 will snap into notch 88.
