' FREDERICK W. KASSLER, OF ST LOUIS, MISSOURI.
, COIN-CONTROLLED LOCK.
Application filed December 29, 1925., Serial No. 78,206.
The present invention relates to improvements in coin controlled locking mechanism, and is peculiarly adapted for application to a door or other swinging closure such as is commonly employed to guard the entrance to pay-as-you enter compartments. However, the lock is capable of a wide and varied field of utility and may be associated with swinging closures, sliding closures, and other types of doors, box covers, vending machines,
etc.
Oneobject of the invention is to provide a lock in which the last coin inserted will be visible at the exterior of the lock until the lock is subsequently operated by. an-
other coin. Thus, when the lock is used to control pay-as-you-enter compartments, a spurious coin will be visible to an attendant during the time that the person passing the coin is in the booth or compartment controlled by the lock. I
A further object of the invention is to provide novel method 0f attaching the lock casing to a door, in such a manner that it cannot be removed from the outside of the door by the use of screw drivers or similar tools. More specifically the attachingscrews for the lock casing are concealed and housed by the plate which covers the coin compartment, this plate being retained in place by a key operated locking mechanism,-and beinginipossihle' for a wet coin to stick in the paseways, a circumstance which frequently arises when gravity is relied upon to effect coin ejection. g p
A further object of the invention is to provide means for rejecting coins of smaller opened. By virtue of this construction itis should be used to operate the lock. mechanism is preferably in the nature of a coin chute so constructed that the proper coins .will'be directed into operative position, and the smaller coins will be by-passed into the box without enterin an operative position. A further feature is the arrangement, by which the small coins will fail to operate the registering mechanism or the indicating mechanism of the lock, even if the coin should by accidentreach operating po sition.
A further object of the invention is to providea lock equipped with indicating or signalling mechanism, registering mechanism, mechanism for preventing the insertion of a coin while the compartment, is occupied, spurious coin indicating mechanism, and rejectsize and denomination than the coin, which This ing mechanism for improper coins, so that i the lock will be substantially foolproof in; operation.
Further objects are to provide a lock of rugged durable construction, which is extremely unlikely to get out of order, which will be highly efficient in use, and which may be manufactured with comparative economy.
l ilith the above noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter setforth andpointed out in the claims. The invention may be more fully understood fromthe following description in connection with the accompanying drawings wherein-- 1 is a view in frontelevation showing the lock applied to a door. I

Fig. 11 is a similar view, but showing the position of the parts when the inside knob fill The lock casing is in the nature of a rectangular box, including a front Wall 15, side walls 16, top and bottom walls 17, 18, anda removable rear wall 19. In attaching the lock casing to a door such as 20, the back plate 19 is first secured in position by the use of suitable securing devices such as the screws 21. upper corners, hook shaped lugs 22 adapted to engage with pins 23, projecting inwardly from the side walls 16 of the casing. At the lower corners of: the plate 19 there are provided projections 24 having threaded sockets 25 therein for the reception of screws 26, these screws passing through openings in lugs 27 fixed to the lower corners of the front wall of the box.
It will be noted that the lower front wall of the box is offset as at 28, and that this offset portion provides an opening 29 at the box front. Within the opening there is an inwardly projecting flange 30 adapted to serve as aseat for a removablerplate 31. The projections 26 terminate flush with the outer face of the flange 30. Secured to the rear face of the cover plate 31, adjacent the lower corners theerof, are a pair of books or lugs 32 adapted to engage behind the flange 30. The cover plate carries a lock casing 33 for a conventional type of tumbler lock shown in elevation at 34 (Fig. 1). The lock 34 is adapted to actuate a bolt 35 engageable with the upper portion of flange 30, whereby when the hooks32 are engaged with the lower portion of the flange, and a suitable The back plate carries at its key inserted to project the bolt 35, the heads of the screws 36 are concealed and it is impossible for one to remove the casing from the door by the use of a screw driver. Any unauthorized removal must be accompanied by the use of a key to retract bolt 35 to gain access to the attaching screws 26.
The plate 31 in addition to its function as a concealing means for the screws, serves as the closure for the coin compartment, which is constituted by the lower end of the box.
At the upper outer edge of the casing there is provided a coin reception slot 36 surrounded by a guiding device 37 for directing a 'coininto the slot 36. Secured to the inner face of the front wall of the casing are a number of guide ways 38, 39 and 40 for the bolts, to be later described. 7 Bolts and keepers.
Slidable transversely of the casing between the guides 38 and 39 is a, locking bolt 41, the end of said bolt being engaged by spring 42 mounted on a suitable supporting stud 43. This spring tends to normally urge the locking bolt outwardly through an opening 44 (Fig. 12),, in the side wall 16 of the casing. Mounted below the locking bolt 41 is a second bolt 45, sliding between the guide ways 39 and 40. The inner end of this bolt is acted upon by a spring 46 'mounted on a supporting stud 47, and normally urging the bolt to fully projected position through an opening 48 (Fig. 12) in the side wall of the casing. v
The projecting ends of the bolts'41, are bevelled as at 49 and 50 respectively for camming engagement with the edge 51 of akeeper. The keeper is in the nature of a casing 52 secured in any suitable manner as by lugs 53 passed through ears 54 to the frame 55 for the door 20. Preferably the keeper is cut away as at 56 for the reception of a guard plate 57 forn'iing an extension of the front wall 15 of the lock casing, this'guard plate preventing insertion of a sharp instrument into the keeper to forcibly retract the locking bolt.
The keeper is formed with a central web 58, and a roller 59 carries trunnions 60 turn ing in the web and 1n one end of the keeper,
this roller being accommodated in a cut away portion 61 of the keeper.
When the door 20 is closed,- the roller 59 always engages with the bolt 45 to retain the same in retracted position, and whenever the locking bolt 41 is retracted to permit the door to open, the bolt 45 will spring outwardly under the influence of its spring 46 as soon as it clears the roller 59. The n'ieans for latching the locking bolt 41 in retracted position includes a pawl 62 pivoted on stud 63 and formed with teeth'64 adapted to engage with a pin 65 projecting rearwardly from the bolt 41. The pawl is normally urged into position to engage thepin by a spring 66 anchored to a stud 67 and acting on a stud 68 projecting from a pawl operating extension 69. The extension. 69 is curved to offer eamming surface 70, against which a stud 71 on the bolt 45 bears when the bolt 45 is in retracted position. Thus, when the bolt 45 is retracted it swings the pawl 62 into the position shown in Fig. Bearing in mind the fact that the bolt 45 cannot be projected while the door is closed, and that the bolt 41 must be retracted in. order to permit opening of the door, it will be seen that as the door is opened, with the bolt 41 retracted, the bolt 45 springs outwardly, releasing extension 70 and permitting spring 66to swing the teeth 64 into latching en-" gagement with the pin 65. Conversely upon closing of the door, the roller 59 forces the bolt 45 inwardly, acting through the stud 71 and extension 69 to trip the pawl and release the bolt 41. e
The invention as thus far described is applicable to Various types oi locks other than coin controlled locks. For instance I have shown a tumbler lock 72 secured to the front wall 15 of the lock casing, said tumbler lock being operated in aconventional manner by akey (not shown). This lock may include a rotary element 73 carrying a crank arm 74 which engages in a notch 75 in the bolt 41 to effect retraction of the latter. Thus the bolt 45 serves to control thelatching and releasing of the bolt 41 independently of the other instrumentalities which may be utilized to retract the bolt 41.
00in delivering and rejecting mechanism.
deliver coins directly into the'lower end of,
the lock casing. Chute-SO as best seen in Fig. 10, includes a transversely disposed attaching arm 81. One apertured end of this arm is screwed as at 82 (Fig. 6) to a lug-83 projecting rearwardly' from the face of the bolt guide 89. The other apertured end of the arm 81 is secured as by screw84 to a bracket 85 projecting rearwardly from -a brid in iece 86 this brid in niece bein b b 7 h 23 F countersunk in the bolt guides 38, 39, and
being accommodated in a cut out portion 87 (Fig. 2) of the locking bolt 41.
Between the coin chutes 77 and 80, there is interposed a transverselyextending plate 88 having a selector slot- 89therein.
It will of a coin for operating the look. We may assume that the coin 7 6 which elfeots operation, is a nickel. In this instance the slot 89 will be of such a width that it will block the passage of nickels therethrough, and will permit the free passage of pennies. Thus, when a penny is inserted'through the entrance opening 36, it will slide down the chute 77, pass freely through the slot 89 and be guided by the chute 88 directly into the bottom of the casing. When a nickel is inscrted, it will pass down the chute 77 partially through the slot 89, where it will be checked by the end walls of said slot. The walls of the slot 89 serve as a flipping or turning device to turn the nickel over, and alter the path of its gravitational movement, so that it will slide over the guiding depending apron portion 90 ofthe plate 88, will pass through a slot 91 in the bolt guide 38, and will enter a slot 92 in the looking bolt 41. This slot may be plainly seen in Fig. 6, and it will be noted from Fig. 4 that the slot extends, all the way through the locking bolt and through the bolt guiding member 39, so that when the coin reaches smaller coin directly to the bottom of the lock casing Without effecting operation of any part of the mechanism.
0oin-controlled bolt-operating mechanism.
Projecting through the front wall of the casing andhaving bearings in the bolt guiding member 40, is a spindle 93 carrying an operating handle 94 at its outer end. At its inner end, the spindle carries a crank arm 95, from the free end of which a pin 96 pro jects forwardly into a slot 97 cut in the bolt 41. The crank arm may be connected to the 'spindle'93 .in any convenient manner, as by screw 98, and a spring 99 acting on the crank arm and anchored to a stud 100 normally retains, the crank arm swung to the position of Fig. 2, in which position the crank arm abuts against a stop shoulder lOlon the bolt guiding member 39. v
The slot 97 in the bolt providesclearance for. free turning movement of the crank arm to the rightwh en there is no coin in place in the slot 92. By operating the handle 94,
' the crank arm 95 may be swung freely from i the position of Fig; 2 to the position of Fig. 3 where it is stopped by the bracket 85. When a. coin is in the operative positionshown in Figs. 2 and3 however, movement of the crank arm '95 to the right, causes the pin 96 to engage with the coin, and by virtue of the coin engaging the right hand end of the slot 92, the lock bolt is retracted or shifted to the position of Fig. 2 through the intermediacy of the coin.
It will thus be noted, that by inserting a coin into the lock, and turning the handle 94, the locking bolt l1 will be retracted, and as the bolt is held in retracted position, and the door bolt opened by the handle 94, bolt -15 will be released by its keeper roller 59, and will spring upwardly, thereby releasing the pawl 62 and permitting the pawl to engage the pin on the locking bolt 41, whereby the locking bolt is held in retracted position.
When the user steps inside of the compartment controlled by the lock, and grasps the inner handle 103, closing the door after him, the bolt 4:5 will again be retracted as it engages the keeper roller 59, thereby engaging the tail piece of the pawl 02, and tripping the pawl to release the locking bolt 11 which will again spring into locking position.
00in displaying and ejecting mechanism.
In 2 it will beseen. that the bolt 45 has a slot 104 therein adapted to register with the slot 92 in the bolt 4-1. In order however, to prevent the loss ot a coin by the accidental release of the handle 9 1 after the coin has been inserted and the handle turned to retract the bolt, I so arrange the slots 10 1 and 92 that they do 110111110913 into registration until after the door has been opened. In other words, as the dooris opened and the bolt 415 is urged by its spring 16 to projected position, incidentally latching the retracted bolt 41, the slots 92 and 10-1 will register, and the coin will drop through the slots between a plate 105 and a window 106 in the front of the casing, at which point the coin is supported by a pin 107 until such time as another coin is inserted and the look again operated.
By virtue of this construction, the last coin inserted will always be exposed through the window 100 and the attendant who is usually employed to take care of a number of coin controlled booths, will be otlered a visible indication of any spurious coins or slugs which have been used to operate the lock. It will be noted that this indication will be available while the patron is still in the booth.
The pin 10-? (Fig. 2) is carried by one arm 108 of a bell crank, the shorter arm 109 of which is t'ulcrumed on a stud 110 secured tothe rear face of the plate 105. The elbow of the bell crank has a slot and pin communication 111 with the lower end of a link 112, said link being pivoted at its upper end as at 113 to an operating arm 114: which in turn is pivoted at 115 to the bolt guiding member 38. A. coiled contractile spring 116 acting on the end of arm 1'08 and anchored to a stud 117 secured to the lower end of the plate 105, normally retains the bell crank in the position of Fig. 2. In this position the pin 10? is in operative position to prevent a coin from dropping below the window 106, and in this position also, the link 112 is pulled downwardly, and the operating arm 114-. is depressed so that a camming extension 118 tormingpa-rt of this arm is disposed in the path of a coin 76 resting on the bolt 15 in operative position to effectre turn engage with the camming extension 118 of the operating arm 11 1. lifting the operating arm, pulling the link 112 upwardly, and swinging the bell'crank 108 to the po sition of Fig. 3 against the action of spring 110, wherebv the coin supported on the finger 107 will be released.
in this connection it is to be noted, that it a' coin should be sticky or moist and tend to adhere either to the glass window or to the plate 105, it will be positively ejected by an incoming coin. That is to say, the "new coiii dropping through the slots 92 and 104: will strike the coin before the window" and tend to dislodge it, and it the coin is not.
dislodged by this action, it will'b'e positively ejected as the corner 119 of the slot 10 1 engages the upper coin and exerts a downward Cfillflflll'fig' action thereon.
amenZZy-controllecl bolt-operating mac/ 1a I his m;
I. have previously described the manner in which the lock may be opened byturning the outer handle 9 after the insertion of a. CD111, and the manner in which the locking bolt automatically snaps back to locking position when the door is closed and the patron enters a. compartment. It is obviously 'necessary to provide some means for permitting; the patron to open the door from theinside to gain egress from the compartment.
With this end in view. the knob 103 above mentioned, is connected to a spindle 120 hav-' ing bearings in the back section 19 'o'fthe.
casing. The spindle at its iniier'end carries crank 93111 121 (Figs. 10and -11),'which may be formed with an extension 122in the nature of a spring finger. Crank-arm 121,
acted on by a spring 123 indicated in dotted lines in Fig. 1 as anchored to a stud 124 on the rear plate of the casing. This spring normally urges the crank arm 121 to the'left, or to the position of Fig. 10 where it is stopped by lug 125 on the rear casing plate 19. As the knob 103 isturned to the right to shift the crank arm 121 to theposition of Fig. 11, the crank arm engages with an ear 126 on the inner end of the locking bolt 41, whereby the bolt is manually retracted and the door may be opened. Closing the door after a patron has left the booth, eil'ects resetting of the locking bolt in the manner above described.
Registering mechanism.
Secured to the side wall- 16 ofthe lock casing as by screws 127, is a register 128 which may be of entirely conventional con struction. The numeral wheels of this register are exposed through a window 129 in the casing wall. The operating lever 130 for the register 128 is connected by link 131 to an arm 132 of a bell crank including a second arm 133 pivoted as at 134 to the rear face of plate 135. The elbow of the bell crank is connected by link 135 to a lever 136 fulcrumed at one end on a stud 137 secured to the front wall of the casing. Lever 136 is formed with a rearwardly extending block or lug 138, to which the upper endof link 135 is pivotally connected. Lever 136 is engaged by an extension 139 of the operating arm 114 as this arm movesupwardly. Thus retracting of the locking bolt through the intermediacy of a coin,-'lifts the arm- 114, lever 136 and link 135. Link 135 acts through the bell crank 133, 132, and link 131 to swing the operating arm 130 of the register to the right and cause the device to register once.
There is a positive return for the register operating mechanism controlled through the intermediacy of the crank arm 121 operated by the inside handle knob 103. It is for this purpose that I provide the spring finger 122 on the crank arm 121. Pivoted at 140 on a guide bracket 141 for the lever 136is a bell crank including arms 142 and 143. The arm 143 carries a pin 144 adapted to be engaged by the finger 122 as theknob 103 is turned to the right, and the arm 142 engages the block or extension 138 on the lever 136 to positively efiect depression oflever .136 and link 135.
As a patron leaves the compartment, he is compelled to turn the knob 103 in order to unlock the door, and as this knob is turned, the train of linkage for the registering mechanism is reset.
Indicating mechanism. The lever 136 which is shown in plan in Fig. 9, includes the enlarged end 145, formed with a shoulder 146 engaged by the extension 139 and operating arm 114. At this enlarged end of the lever 136 there is displayed suitable indicia 147 seen in Figs. 1
and 9, and comprising, the words Vacant and Closed, or Vacant and Occupied. The normal position of lever 136 shown in Fig. 2, and with the lever in this position, the word Vacant will appear through the window 148 in the front of the casing. lVhen a patron inserts a coin, opens the door, and enters the compartment, the position of the lever will be shifted to that shown in Fig. 3 as above noted, and the Closed sign will appear at the window. WVhen the patron leaves the compartment, and turns the knob 103, he effects not only resetting of the registering mechanism, as above described, but resetting of the indicating lever 136 to again show the Vacant sign through the window 148.
00in blocker.
Means is provided for preventing the in-' sertion of a coin through the slot 36 when the compartment is occupied. This means includes a, U-shaped yoke 149, the legs of which are pivoted as at 150 on studs projecting laterally from the side walls of the coin chute 77. One leg includes a tail portion 151 curved for coac-tion with a camming roller 152 mounted on the block 138. The other leg of the yoke is acted upon by a light torsional spring 153 (Fig. whichserves to retain the yoke in the operative position of Fig. 4.
When, through the intermediacy of the operating arm 114, the indicating lever and the block 138 are lifted, the roller 152 ongages with one arm of the yoke 149 and swings the intermediate portion 154 of the yoke into position to efl'ectively block the insertion of a coin through the slot 36.
The return movement of the coin blocker to inoperative position is effected nonpositively; that is to say, the resetting mechanism which restores the indicating lever 136 to the position of Fig. 2, simply withdraws the roller 152 fromengagement with the coin blocker and permits the light restoring spring 153 to act, and return the coin blocker to the position of Fig. 4. It will of course be understood that this spring is not powerful enoughto reset the registering mechanism or the indicating lever, and that these mechanisms can be reset only through the positive action of the bell crank 142, 143. In connection with this bell crank, it may be noted that it is normally held in the position of Figs. 2, 3 and 10 by the action of an associated spring 155 Operation.
. It is believed that the operation of the locking mechanism will be entirely clear from the above detailed description, but it may be well to summarize the manner and times at which the various parts of the mechamsm are operated.
We will assume that the compartment is empty, that the indicating lever is in the position to show a Vacant sign, that the registering mechanism has been. reset after its last operation, and that the door is closed. In this position the locking bolt 41 is projected and the bolt 15 is held in retracted position by the roller 59. I
A coin is inserted in the slot 36. If this coin is of improper denomination it drops through chutes 77 and 80 into the bottom of the box. If the coin is of the proper denomination it drops through the chute 77, is flipped over by the plate 38 and guided into operative position in the slot 32, resting upon the bolt 11. The handle member 9-1 is now turned, causing the pin to shift the coin 76 to the right in Fig. 2, thereby retracting the bolt 11. Simultaneously with the retraction of the bolt, the coin the camming extension 118 of the operating arm 114:, and actuates the following mechanisms. Pin 107 shifted by its link 112 to release a coin before the window 106. The indicating lever 136 is swung to a new position, e: posing a Closed sign through the window 148. Movement of this lever cts through the roller 1 2 to move the coin blocker to operative position, closing the mouth of the entrance slot 36. lifovement of this lever also acts through linkage 135, 133,132 and 131 to actuate the register 128.
It will be borne in mind that all of these operations have been taking place as the locking bolt was being retracted and before the door has been opened. As the door is opened, the bolt e15 springs outwardly, permitting the coin to fall through the slot 10 1 in the position before the window 106. Outward movement of the locking bolt also releases the pawl 62 vnich latches the locking bolt in retracted position. the coin drops down through the slot 1041-, the operating arm 114 is released, and the spring 116 restores the pin 107 quickly so that it engages the new coin and holds'it in place before the window.
At this time the coin blocker is still in blocking position, the indicating lever still shows a Closed sign, and the register has not been reset. The patron now enters the compartment and closes the door, whereupon roller 59 engages lever 15 which trips the pawl 62 and releases the locking bolt 11. The latter springs outwardly, and the door is again locked. No other mechanism is effected by closing the door.
When the patron grasps the knob 103 to open the door from the inside, the locking bolt 11 is again retracted by virtue of the engagement of the crank arm 121 with the lug 126. At this time also, linger 122 acts through the bell crank 1 12, 143 to reset the registering mechanism and shift the indicating lever so that the latter displays a Vacant sign atthe window 1&8. This move ment of the lever 136 permits the spring 153 to restore the coin blocker to inoperative position out of the path of coins entering through the slot 36. As the patron leaves the compartment and closes the door, the bolts are relatched in the manner above described without affecting any of the'othcr mechanism. r
Attention has been previously called to the rotating operating linger 7 4 which is operated by a key inserted in the lock 72, so that an attendant may gain access to the compartment. Operation of the bolt by this look does not affect the indicating inechanism, registering mechanism, or the coin holding pin 107.
In the event that a penny, by virtue of slightly sticking to the coin chute 77, or in some other manner, should drop into the slot 92 in the locking bolt, the penny. will function to permit opening of the lock. However, the penny cannot effect operation of the indicating mechanism or registering mechanism because it will be too small to engage with the camming extension 118 of the operating arm 114. Furthermore this penny will be prominently displayed before the window 106, and will be promptly dis covered by an attendant.
Various changes and alterations mightbe made in the general form and arrangement of parts described, without departing from the invention. Hence I do not wish to limit myself to the details set forth, but shall consider myself at liberty to make'such changes and alterations as fairly fall within the spirit and scope of the appended claims.
