23 Claims.

This invention relates to coin-controlled mechanisms, and consists of improved coin-controlled locking means for doors of washrooms, dressing rooms, toilets, baths and other public or semi public compartments where a fee is required of each user. The improvements are particularly related to a type of lock such as that shown and described in my United States Patents No. 1,568,- 770, dated January 5, 1926 and No. 1,611,681, dated December 14, 1926, and coact with a type or coinoperated mechanism such as is disclosed in my United States Patent No. 1,782,768, dated November 25, 1930.

One object of the invention is to provide a coin-- lock for compartment doors which will be at all times in condition to receive a coin save while it is being actuated with a coin therein.

Another object of the invention is to provide a compartment door coin-lock which after a coin is deposited may be controlled from without the compartment until the bolt of the lock is drawn independently of the outer control.

Another object of the invention is to provide a compartment door lock wherein the coin-operated mechanism is adapted to be actuated from the outside of the compartment to draw the lockbolt and completely returned to original coinreceiving position without disconnecting the lockbolt for actuation from outside the compartment.

Another object of the invention is to provide a compartment door coin-lock for consecutively discharging the coin and unlocking the door by a single movement of the outer handle of the lock, and for insuring the return of the coin-carrier to original coin-receiving position immediately thereafter.

Another object of the invention is to provide a closure mechanism for a compartment which is reliable to secure protection against unauthorized tampering and easily operative to afford the attendant ready access to the mechanism.

Another object of the invention is to provide a revenue collecting closure means for a comparto ment which will be compact in arrangement, effi- (Cl. ISM-83) the adjacent keeper, and showing the compartment door locked;

In its present embodiment the invention is applied to a coin-lock for compartment doors which includes a back-plate fast upon the door at the keeper for supporting the lock-casing, a coin-slot in the casing, shafts extending through the easing and door for operating the lock, and a coinoperated mechanism on one of the shafts for controlling the operation of the lock. Also included is a conventional till for collecting and means for counting the coins, together with auxiliary locks for protecting the till and permitting access to the compartment without use of a coin. These features will be described only generally since their nature and method of operation are well known in the art.

In the drawings, the machine comprises the generally rectangular back-plate 1 having at each corner a hole 2 for receiving a screw 3 to secure the plate upon the outer surface of the door D. The oblong box or casing 4 for the lock is adapted to be secured to the back-plate 1 by opposite screws 5 threaded into perforated lugs 6 at the bottom of the casing, and a plate '7 slidably mounted on opposite lugs 9 at the top of the back-plate. From the inner surface of the casing 4, as seen in Figs. 3 and 4, a lug 11 projects. EX- tending from the plate 7 is a stud 12 which is held on the upper edge of a disk 13 fast on the forward end of the tubular shaft 14 whereby to hold the plate 7 in engagement with the lug 11. The opposite end of the tubular shaft 14 is squared at 15 to receive a handle 16 to permit the disk 13 to be turned from the inside of the compartment. Pivoted on a screw 1'7 fast in the back-plate 1 below the tubular shaft 14 is a stop-plate 18 which normally rests against a stud 19 on the back-plate to prevent the disk 13 from turning to permit the plate '7 to be lowered. At the edge of the back-plate 1 spaced brackets or lugs 21 hold a spring 22, one end of which engages an ear 23 of the disk 13 to normally urge it in a clockwise direction against the stop-plate 18. In the top of the lock-casing 4 is a small aperture 24 for receiving an awl or similar implement, not shown. By turning the handle 16 to turn the disk 13 against the pressure of the spring 22 from the stop-plate 18 the latter may be manually turned on the screw 17 away from the stud 19. When the handle 16 is released the pressure of the spring 22 causes the disk 13 to be rotated beyond the stud 12. The awl may then be inserted in the aperture 24 and the plate '7 depressed to clear the lug 11. Upon removal of the lower screws 5, the casing 4 is then free to be withdrawn from the back-plate 1 in order to permit access to the coin-operated mechanism therewithin.

The front of the casing 4 is recessed at 25, see Fig. 5, to permit access to the stop-plate 18 and the till without detaching the casing from the back-plate 1. The recess 25 is normally closed by a closely fitting rectangular plate or cash-door 26 which is adapted to be made fast therein by means of the lock 2'7 engaging a lug 28 on the inside of the casing.

In horizontal alinement with the keeper 29 and a stop-lug 30 fast on the side of the casing 4, a bolt 31 is supported for horizontal movement by a bracket 32 fast on the back-plate 1. At the inner side thereof the bolt 31 is slotted at 33 to receive the bracket 32 and at its outer end is slidably mounted between the opposite lugs 34 fast on the back-plate 1. The upper end of the spring 22 urges the bolt 31 toward the keeper 29, a shoulder 35 on the bolt engaging the lower lug 34 to retain the bolt within the casing 4. Depending from the bolt 31 below the slot 33 is a leg 36 engageable by the disk 13 when the inner handle 16 is turned to withdraw the bolt from the keeper toward the stop 30 to open the door.

Above the bolt 31 a cylinder-lock 37 is let into the casing 4. Upon the rear end of the bolt 31 is a lateral lug 38 which is adapted to .be engaged by an arm 39 mounted on the lock 3'7. The lock 3'? maintains the arm 39 normally in the inoperative position seen in full lines in Fig. 11, subject to be turned by means of the attendants passkey to the position shown by broken lines. In the latter condition the lug 38 is engaged to draw the bolt 31 from the keeper 29 against the spring 22.

The coin-operated mechanism is carried on a horizontal spindle or shaft 40 journaled in bearings 41 in the front of the casing 4. The shaft 46 projects into the tubular shaft 14, being adapted to be freely rotatable therein as seen in Fig. 3. The shaft 46 is adapted to be manually rotated from a bar or handle 42 secured to its forward end, the handle being rotatable without the casing 4 to provide for convenient manipulation. Fast on the shaft 40 is a ratchet-plate 43 connected by screws 46 to an opposite rearward plate 48. The screws 46 pass through shouldered members 49 which space the plates 43 and 48 in parallel relation. Fixed between the plates 43 and 43 is an inclined coin-rest 51 provided with a longitudinal slot 52, the parts last described constituting in their assembled relation a coin-carrier, hereinafter designated in general by the reference character 55.

It will be observed that the coin-carrier 55 is rockable about the axis on the shaft 40 by means of the handle 42. A wire spring 56 coiled around the shaft 40 has one end 57 fastened to the coinrest 51, and its opposite end 53 is held under tensicn against the side of a stud .59 which projects on the inside of the casing front. The spring 56 tends to maintain the coin-carrier 55 in the position of rest illustrated in 4 with the ratchetplate 43 swung back beyond the coin-slot or way 62 shown in Figs. 1 and 2. With the coin-carrier 55 in this position the coin-rest 51 is alined with the coin-slot 62 whereby to adapt it to receive the coin inserted therethrough and the spring 56 acts to return the coin-carrier to this position after each swinging movement thereof by the shaft 40.

A pawl 63 pivoted at 64 to the front of the casing 4 is urged by a spring 65 upon the teeth 66 on the rearward edge of the ratchet-plate 43 to prevent the return of the coin-carrier 55 unless or until the coin is discharged from the carrier, this part of the mechanism being specifically described in my patent referred to last above. Suf fice it to herein state that the pawl 63 engages with the teeth 66 on the ratchet-plate 43 when the coin-carrier 55 is operating with a coin in place thereon to prevent retrogressive movement of the carrier. The pawl 63 does not cooperate with the ratchet unless a coin is in place on the carrier, being held from engagement with the teeth thereof by an element 65 termed the presser-plate which forms the energizing means for unlocking the mechanism. The presser-plate 67 has a cam-shaped edge 68 which normally holds the toe of the pawl 63 away from the ratchet 43, as seen in 4, by means of a spring 69 on the stud 64, the spring 69 being connected to a tie-rod '70 pivotally mounted on the plate 67.

The presser-lever 67 has its hub 71 mounted free to turn on the cross-shaft 40 and is formed with a lateral stud '72. A connecter-plate 73 is slotted at 74 for sliding movement transversely on the shaft 40. At its upper extremity the connector-plate 73 is forked at 75 to receive the lower bushing 49 whereby the plate '73 is connected to be carried across the shaft 40 by movement of the coin-carrier 55. The plate 73 is recessed at 76 to receive the stud 72 and is provided with a finger or coin-presser '7'? which projects through the v55 is in position to receive the coin as indicated by dotted lines in Fig. 4. The end of the coinpresser 7'7 is adapted to engage the coin in the carrier 55 to cause the presser-lever 67 to be moved with the carrier by the connecter-plate '73 to unlock the doorfrom the outside.

In order that the coin may act positively against the finger 7'7 it is held against the coinrest 51 by means engaging its edges. As shown in Fig. 5 the ratchet-plate 43 is formed with an car '78 bent to overhang the edge of the coin as the latter slides down to position upon the rest. At the opposite side of the coin-rest 51 is a coi11- holder comprising a lever '79 pivoted on a stud 80 fast on the rear plate 48. The coin-holder '79 has an offset portion 81 adapted to overlie the edge of the coin whereby it cooperates with the car '78 to hold the coin against the rest 51. The coin-holder '79 is normally held in position to engage with the coin by a spring-pressed detcnt latch 82 pivoted between the sides of the coincarrier 55. The detent-latch 82 has a lateral arm 83 which is normally engaged on the edge of the coin-holder '79 to space the lower end of the latch from the coin-rest and permit the coin to slide therebetween to position upon the car '78 and offset portion 8. The latch 82 has a depending dog 84 which engages the coin-holder '79 to main tain the latter in coin-retaining position until the throw of the coin-carrier 05 has been almost completed, whereupon a tailpiece or striker 85 of the latch engages the side of the casing 4, see '7, to rock the dog oil the coin-holder and permit it to swing upwardly to release the coin.

A contact-member or arm 86 formed on the presser-lever 67 extends upwardly to engage depend ng pivoted fingers 8'7 an 33 of the counter 89. When the presser-lev r 67 is turn d with the coin-carrier 55 to unlock the door, the arm 86 lifts the finger 8'7, see Fig. 6, to change the reading 'of the counter to record the coin in the carrier. after discharge of the coin and the retraction of the lever 6'7 upon the pawl 63 the arm 86 engages the finger 88, causing it to pivot to the position seen in Fig. "I and thereby reset the counter 89 for the next coin. M

Fast on the presser-leverd? is referably a projecting bracket 91 having a bent-over portion or lifter 92 which extends along the rear surface of the plate 18. If desired, the lifter 92 may be integral with or attached directly upon the presser-lever 6'7. Adapted to radially alined with the bent-over portion 92 in respect to the axis 40 is a lug or driver 93 which projects rearwardly from the plate 18. When a coin has been deposited and the handle 42 turned the bent-over portion 92 and the lug 93 move together in concentric paths to draw the bolt 31 against the spring 22 by connecting means described hereinafter.

A feature of the present invention comprises connecting means on the bolt 31 for unlocking the door with the front handle 12 only when a coin has been deposited in the slot 62, which is adapted to prevent retrogression of the coincarrier until the coin has been discharged and to insure the immediate full return of the carrier to coin-receiving position whereby the lock always in condition to collect revenue save while the front handle is being operated. Fur thermore, the connecting means permits the handle a2 and bolt 31 to be operated any num-- ber of times after the coin has been discharged until the bolt is subsequently operated independently of the handle 42, such as when the door closes upon the keeper, or the inner handle turned. In the instant embodiment of the invention, said connecting means includes a coun tersunk screw 94 fast in the leg 36 of the bolt and projecting from the forward surface there of to receive a flanged nut 96 screwed ti -dy thereon, see Figs. 12 and 13. Pivoted on the core 9'7 of the nut 96- is a lever 98 having a hub 99 and

arms

101 and 102 extending radially therefrom. The

arms

101 and 102 are spaced by the hub 99 forwardly from the leg 36 to provide room therebetween for an arcuate bar or link 10%. One end of the link 2104 is pivotally connected with the extremity of the arm 101, the latter being bored to receive a stud 10'? fast on said link end.

At the free end, the link 104 is formed with upper and

lower lips

108 and 109 which are adapted to be engaged by the lifter and driver members 92 and 93, respectively, in a manner to be later described, to open the look. at the ivot end the link 10 1 is provided laterally with upper and lower flanges 111 and 112, respective ly. One end of a spring 113 coiled around the core 9'7 is seated in a notched foot 114 on the leg 36. The other end of the spring 113 is retained by an ear 116 to bear against the lower flange 112 to urge the lever 98 to rotate on the core 9'7 in a clockwise direction.

Referring to Fig. 8, the lever 98 is normally held by the spring 113 to maintain the link 10 1 substantially in the horizontal with the lower edge thereof resting upon the convolutions or the spring 113 on the core 97 and the upper flange 111 pressed against the lower edge of the bolt 31. The pressure of the spring 113 velops sufficient f iction between the flange and the bolt 31, and the flange 112 and spring 113, respectively, to retain the lir against gravity in any position it may be tu to on the stud 107. 10 i is curved at 117.

When the door is locked the link 104 is below the plane of the bracket 32, consequently when the bolt 31 is drawn against the spring 22 link does not touch the bracket. However, i the link 104 has been raised and the bolt drawn, the lower end of the bracket 32 or on the curved edge 117 and pushes the linl; down to normal horizontal position, see Fig. 11, if the link is unsupported save by the pressure of the spring 113. When the link is supported in raised position by means in addition to spring 113 such, for instance, as by the lifter de- 111 the we .ied The upper edge of the link 92, and the bolt 31 is pushed by the driver lug movement of the curved edge 117 upon the bracket 32 will force the lever 98 to pivot on the core 9'7 against the spring 113, as seen in Fig. 10. Upon withdrawal of the lifter 92 and driver-lug 93 the bolt 31 is expelled by the spring 22 and the lever 98 is returned to normal position by the spring 113. Due to the friction on the upper and lower flanges 111 and 112 however, the return of the link 10 1 is only partially effected, it proceeding only until the curved edge 117 leaves the bracket 32; and the link 10 1' is left suspended with its upper and lower lips 1G8 and 109 straddling the arcuate path of the.

driver-lug 93.

The construction and arrangement of the device having now been described in detail, the method of operation of the connecting means in conjunction with the coin-operated mechanism will next be explained.

Coin-locks of the type herein considered are 1:

lilo;

usually applied to doors having spring hinges or other suitable means for constantly urging the door to closed position to cause the bolt to be slid inwardly upon the bracket 32 when passing over the keeper 29 before locking therein. The elements of the connecting means on the bolt 31 are therefore normally at rest, with the link 104 resting in the horizontal on the nut 96 and the lever 98 held by the spring 113 against the lower edge of the bolt 31, as shown most clearly in Fig. 8. The coin-operated mechanism is also at rest as shown in Fig. 4, the coin-rest 51 alined with the coin-slot 62 to receive a coin therethrough, the presser-plate 6'7 being held upon the pawl 63, and the connecter-plate '73 held by the shouldered spacer 49 to engage the stud 72 in the recess '76.

When a coin C is deposited in the coin-slot 62 to open the door, it immediately slides to rest between the ear '78 and offset portion 81, becoming thereby a means for locking the connecterplate '73 in engagement with the coin-carrier 55. The front handle 42 is then turned from the position shown in Fig. 1, swinging the coin-carrier on the shaft 40 in a. contra-clockwise direction from the position shown in Fig. 4 and causing the connecter-plate '73 to shoulder upwardly upon the stud '72, thus rotating the presser-plate 67 about its axis 40. The cam surface 68 is lifted from the pawl 63 to permit the latter to engage the teeth 66 on the cam-plate for preventing retrogresison of the coin-operated mechanism should the handle 42 be released.

As the swinging movement progresses the lifter 92 moves under the lower lip 109 to lift the link 104 to the position shown in Fig. 9 wherein it projects into the arcuate path of the pusher-lug 93. While the pusher-lug 93 advances to engage under the lip 108 and begins to press the link 104 to slide the bolt 31 inwardly from the keeper, the coin-operated mechanism is carried toward the completion of its throw. The striker engages on the side of the casing 4 to tilt the detent-latch 82, thereby removing the dog 84 and permitting the coin-holder '79 to swing diagonally outwardly to remove its offset portion 81 and free the coin. The tension of the spring 69 causes the presserplate 6'7 to urge the stud 72 upon the connecterplate '73 and cause the connecter-plate to swing across the shaft 40, as shown in Fig. 7, and discharge the coin. This movement releases the stud '72, causing the presser-plate 67 to be pivoted quickly to its original position on the pawl 63 under tension of the spring 69. The lifter 92 is thereby returned and the bolt 31 is completely withdrawn from the keeper through the continued rotation of the handle 42, the pusher 93 being engaged under the lip 108. Toward the end of the withdrawing movement the curved edge 11'? of the link 104 engages the bracket 32 which tends to swing the link 104 toward the horizontal about the stud 107. This efiect is prevented by the pusher 93 which sustains the free end of the link 104 causing the bracket 32 to force the pivoted end of the link downwardly against the spring 113, and tilting the lever 98 in a contraclockwise direction.

Referring to Fig. 10, wherein the culmination of this unlocking operation is illustrated, the bolt 31 engages the stop 30 which limits the movement of the pusher 93 and handle 42 when the bolt has been completely withdrawn from the keeper. The handle 42 may then be released causing the coin-operated mechanism to return in a clockwise direction to the position of rest with the coinrest 51 alined to receive a coin through the slot 62. The pusher 93 being thus removed from the link 104 the spring 22 becomes operative to slide the bolt 31 outwardly to its normal position on the lug 34. Sliding of the bolt outwardly moves the connecting means from the bracket 32 and the spring 113 swings the lever 98 in a clockwise direction, lifting the pivoted end of the link 104 until the upper flange 111 engages the lower edge of the bolt 31. Although the pusher 93 has been withdrawn from the lip 108 the link 104 remains elevated above the nut 96 and in the arcuate path of the pusher due to the friction between the flange 111 and the bolt edge, and the flange 112 and the spring 113, respectively.

The patron, having once turned the handle 42 to discharge the coin and withdraw the bolt 31 from the keeper 29, customarily opens the door to enter the compartment before releasing the handle. The handle 42 is then released and the door closes upon the patron, causing the bolt to be pressed backwardly by the edge of the keeper 29 as indicated in Fig. 2, the keeper thereby acting to slide the bolt independently of the front handle 42. This movement being accomplished without useof the pusher 93, the camming action 100 of the bracket 32 on the curved edge 11'? causes the link 104 to pivot at the stud 107 to lie in inoperative position upon the core 97. This is illustrated in Fig. 11, wherein it will be observed that the lip 108 is depressed below the arcuate path of the pusher 93, rendering it impossible thereafter to operatively engage the coin-operated mechanism with the connecting means on the bolt 31 without use of the lifter 92. In other words, sliding of the bolt inwardly by its contact with 110 the edge of the keeper 29 disconnects it from control by the handle 42. When the bolt has passed within the keeper it is returned upon the lug 34 by the spring 22, causing the connecting means to be carried away from the bracket 32 in the condition of rest shown in Fig. 8.

Frequently it is found that the patron seeking entrance neglects to open the door of the compartment before releasing the handle 42 to return the bolt 31 to latch within the keeper 29. The link 104 is then held in elevated position to operatively receive the pusher 93 without requiring use of the lifter 92. Therefore, in order to thereafter enter the compartment it is but necessary that the patron repeat the opening operation of turning the handle 42, without depositing another coin. This causes the coin-carrier 55 to swing to bring the pusher 93 under the lip 108 and carry the bolt 31 and connecting means thereon backwardly in the same manner as described above, the pusher supporting the link 104 against the bracket 32 and the spring 113 and the cooperating frictional surfaces coacting to return the link in raised position. Upon subsequent closing of the door, the keeper 29 slides the bolt to lower the connecting link 104 below the path of the pusher 93.

When the patron leaves the compartment the bolt 31 is withdrawn by actuation of the camplate 13 by the inner handle 16, and when the handle is released the bolt is returned upon the stud 34 by means of the spring 22. The door then closes upon the keeper 29, the bolt being slid to pass within the keeper and returned to latch therein. The compartment door coinlock is thus again established as shown in Fig. 4 to repeat the cycle of use as described above.

It will be observed that mounting the connecting means on the bolt 31 simplifies the construction and assembly of the parts of the mechanism,

affording a more efiicient operation and distribution thereof with the lock-casing.

The invention provides a particularly simple device on the lock-bolt for connecting the belt for control by the front handle when a coin has been deposited until the bolt is actuated independently by the keeper 29 or by the inner handle 16. The device thus guards against obliging the patron to deposit a second coin to draw the bolt upon his failure to open the door after first drawing the bolt. By means of the mechanism described the connecting means is positively lowered to inoperative position upon operation of the bolt by means independent of the front handle, rendering it impossible to thereafter withdraw the bolt by means of the front handle until an additional coin is deposited.

After the connecting means is moved to operative position and the bolt is drawn the coin-carrier is automatically returned to alinement with the coin-slot in the casing, thereby restoring the lock to condition to collect revenue without the services of an attendant or the necessity of further manipulation by the patron. Being thus in the condition to receive the coin at all times, save when the front handle is being turned, the lock is especially useful for doors of compartments intended to accommodate a plurality of patrons entering at different times.

Moreover, the device is practically proof against improper manipulation without use of a coin and. the construction of the casing is such that the machine cannot be tampered with and its contents stolen.

While I have herein described and illustrated the device as embodied in a preferred form of construction it is to be understood that the construction and arrangement of the parts of the mechanism may be varied as desired without departing from the spirit and scope of the invention. Therefore, without limiting myself in this respect, I claim:
