, y 30. Whilemy' invention is not limited particularly to a lock employed for any` speciiic purpose,yet, as it is particularly adapted for controlling the lock mechanism oi' doors-for closing compart ments provided iorpublic use, :such as toilets and u' the like, I have illustrated and described my invention herein lin connection VWith such a lock. In theV drawings'herein the numeral I-5 denotes a portion of the door frame o1' jamb of a door opening, as to a toilet compartment, and I6 denotes 1 a portion of the Ydoor that closes such opening.

A keeper plate I1 is secured .to the jamb-infany suitable manner and aiords a support for a keeper I8 having an opening to receive a boss i9 projecting from 'the frontedge ofa lock case 45 2t, said keeper also having a keeperrecess 2i V`to receive rthe outer end of alatoh bolt 22 mounted for reciprocating movement Within the case.V The case 29 is affixed to the front ofthe door I6 and has a back'plate 23. secured thereto in any suit-v 50 able manner for closing the chamber thereinand a coin slotl 24 in the front of the case opens'into the interior therein. A guiding lug'23 projects .from the inner face of the front of the case and has a ledge 26 as shown in Fig. 22 forming a track 5 5 for travel of a coin or token into a dish-shaped coin receiver 21 supported at the end of a coin receiver arm 28 rotatably mounted as hereinafter explained. A knob spindle 29 is rotatably supported at one end in a bracket 30 extending across the case intermediate its front and back Walls, a leg 3l of the bracket being secured to a post 32 projecting from the front wall of the case for the support of one end of the bracket and its opposite end 33 being secured within a recess 34 in the boss i9, as shown in Fig. 4 and in dotted lines in Fig. 9.

A connector comprising a sleeve 35 and a head Y55 `onvthe latch.bolt.22. --having been engaged, by the vuse of a key, with -the notch 39, this being the normal and coin 36 is rotatably mounted in and. extends vthrough the front wall of the case.as shown in Figs. .14

and 1'7, the knob spindle 29 being supported in this connector. A recess intheconnector head 36, encloses a spindle head 31 on the spindle-29, said spindle head carrying a locking bolt 38 having one end movable into aY locking recess 39 on the inner wall of the connector head 36, as shown in Figs. Y 14 and 1'6. rIfl'ie bolt 38 isengaged by an eccentrically mounted pin I4 on the end of a plug 40 of a pin tumbler lock which plug is mounted in the shank of an entrance knob 4I. 'I'his pin tumbler lock is of old and well known construction and afurther and'detailed description is therefore omitted herein. A spring pressed detent 42 inthe spindle -head 31 engages notches in the locking bolt'38 to yieldin'gly retain said bolty in locking or unlocking positions, the detent' yielding, when pressure is applied to the bolt, to enable it to be moved. vThe shank or hub of the knob 4| is secured to the spindle head 31 by means of a screwV I3 as shown in Fig. 15.

The locking mechanism just described is to enable the door bearing the lock case 20 to be opened without the use of La coin. To effect this purpose a key, usuallyin'the possession of an l. attendant'7 is inserted through thev opening in the end of the knobl 4| and into the key slot in the plug 40, said key positioningthe pin tumblers so that the plug 40 may be turned. This will operate the bolt 38 to remove its end from the recess 39 in the 4connector head 36 as shown in Figs. 14 and 16. The key now being turned further, or theknob ifdesired, 4the spindle 29 is rotated within butv independently of the connector 35-36this being'r'effected by reason of the screw I3 (see Fig. 15) which secures the knob shank to the spindle head y31. This operation of the spindle causes a pin 43 projecting from the spindle into a groove 44km the wall of a hole in the hub of a dog 45 to engage a shoulder 46 near the rear end ofthe latch bolt 22,y all as shown in Fig; 10 of the drawings. Continued turning movement ofthe key or knobv effects disengagement of the latch Vbolt from the keeper and permits the door to be opened.

The coin receiver 21 hereinbefore referred to has a shoulderforming aftrack 41 upon which the coin travels from'the track or ledge 26 until the coin islocated within the receiver. A slot 48V isi-formed at one edge ofthe receiver, extending preferably to` yabout the center thereof. A shelf 49. on the arm 28 constitutes a slide for coins from the receiver into a coin box 50 1o-A Ycated underneath theouter end ofthe slide. A latch bolt actuator is pivotally mounted upon the spindle Y29, this actuator comprising a hub 5| through which said spindle extends, an actuating finger 52 extending from the hub for movement into the coinreceiver 21, this finger being adaptedftorengage the bottom of the receiver when not restricted. An actuating d'etent 53 projecting from one side of the hub 5| is positioned to engage the shoulder 46 hereinbefore referred to on the latch bolt22.

In the operation of that part of the structure just described the outer end of the actuating finger 52 will be in a position adjacent to the edge or rim of the coin receiver 21, but spaced therefrom a distance to admit a coin between the two, the linger being held in this position 'by the pressure of one end of a double acting -spring 54 wound around the post 32, and as shown'inFig. 7 of the drawings, the finger in this position resting against a coin releasing lug The locking bolt 38 operating position of the parts, a coin 56 is inf serted inthe coin slot in the case and rolls along the tracks '26 and 41 into the center of the receiver 21 where it is nested between the receiver and theend'of the actuating finger 52, and as shown in Fig. 13 of the drawings. 'I'he knob 4| now being turned, rotation is communicated to the connector sleeve 35 which isy keyed to the coin receiver arm 28, as shown in dotted lines in Fig. 14 of' the drawings. Thisrotates the coin receiver`21 and its support 35 andmoves the coin in the receiver against the end of the finger 52 and the latter is vrotated on its axis, carrying the detent 53T against theshoulder 46 on the latch bolt and moving the latter todisengage it from its keeper and permit the vdoor to be opened, the parts now being in the position shown in Fig. 6 of' the'drawings.

However, before the' receiver 21 can bev moved, as justdescribed, a receiver stop 51 at one end of a pivotallyfmounted stop lever 58 must be moved from the Vpath of the receiver 21. This is effected by engagement of the curved outer side of the finger 52-with a cam`59 on the lever 58, as shown in` Fig., 6 of the drawings. The lever 58 is biasedlagainst the finger 52 by one arm of the double acting spring 54, all as shown in Fig. 6 of the drawings'. With the parts intheir normal positions just previous to the insertion of a coin movementof the receiver is blocked by the stop -511in its path but' a slight space occurs between a coin in the receiver 21 and the stop 51 such that after insertion of the coin the receiver maybe' moved sufciently to enable the cam 59 to ""thro'w' the stop '51 Vout of its path as above described. The object of the stop 51 is to compel insertion of a'coinv to operate the lock and to thereby prevent movement of the receiver without the use of a coin, and as by means of an instrument thrust through 'the' coin slot or by turning therknob 4|. After the knob 4| has been turned sufficiently toldisengage the latch bolt from its keeper to enable the door to be opened, the grasp of the hand upon said knobbeing released, the receiver 21'is returned to the position shown in Fig. 7 under the action of a receiver spring 69 aided by' thespring 54 Yacting on the finger 52 and through the coin which is Vstillin place in the receiver. In ,this movement thenger 52 acting against i the coin releasing lug 55 moves the latch bolt 6 to 9. A stop lug 64 projects from one edge of the carrier 62 to engage the side of the case and thereby determine the active position of the stop as sho-wn in Fig. 6. In this position the outer convex surface of the receiver 21,' or a lug thereon', contacts with the stop 6I and positions the receiver to obstruct the entrance of a coin into the coin slot as hereinbefore mentioned. A spring 65 is secured at one end to a pin projecting from the carrier 62 and at its opposite end to a lug projecting from the wall of the case, the spring being so arranged that as said carrier is swung in opposite directions the spring will pass across the pivot S3 and snap the carrier 62 into one of its opposite positions, depending upon which side of the pivot 63 the spring extends, and in a manner that will be readily understood.

The carrier 62 is operated by an actuating lever 56 pivotally mounted intermediate its ends within the case and having a pin projecting from one end into a slot 61 in the stop carrier 62, the opposite end of the lever being adapted to enter a notch E8 cut into the receiver 2'! in the opposite side thereof from the slot 48, as shown in Fig. 12 of the drawings. In its normal position of rest the stop carrier S2 is located overlying the receiver, as shown in Figure 9. When, however, the knob M is turned to operate the latch bolt 22 and release it from its keeper to enable the door to be opened, as hereinbefore described, the coin located in the receiver 2l closes the notch 68 in said receiver and the coin near its edge engaging the end of the lever SS located in the path of movement of the coin will operate said lever andk swing it into the position shown in Figs. 6 to 8. This places the back stop El in position to engage the receiver 2l and retain it in the position shown in Figs. 'l and 8.

When the door is closed, following the operations just set out, the latchbolt 22 engaging with the edge of the keeper, is thrust ba'ckwardly into the position shown in Fig. 8. In this movement the coin releasing lug 55 on the bolt engages the actuating finger 52 and swings it backwardly, thereby releasing the coin 56 which. drops and slides along the shelf 49 and olf its edge into the coin box 5e. When the door is fully closed and the latch bolt 22 is in position for movement to engage its keeper the finger 52 will be swung forward under the iniiuence of the spring till and engaging the lug 55 on the bolt will move the latter and seat it in the keeper recess, as hereinbei'ore described, the end of the nger 52 now extending slightly into the receiver 2l.

A paid entrance having been gained to "tht compartment guarded by the lock and the door being closed and locked as just described, inrusion will be prevented for the reason that the L sin receiver 2'! being located in front of the coin slot in the case a coin cannot be inserted and it will therefore be impossible to gain entrance'to` the compartment by the use of a coin. In order to open the door an exit lmob 69 is provided on the inside of the door, this knob having a spindle. 'le extending through the door and into the lock case. A clog il projects from the spindle into a notchl2 in the bolt 22 near its outer end for engagement with a shoulder l2 at one end of the notch. The knob being turned the dog engaging the shoulder of the notch retracts the latch bolt and releases it from its keeper so that the door may be opened. This backward movement of the latch bolt Ywill incidentally operate some of the mechanism hereinbefore described, but to no avail. A resetting I5 nnger 1S for resetting the back stopmechanism forthe receiver projects from the hub of the. dog 'Il into positionfor engagement with a resetting pin 'M projecting from the back stop 6|, and as shown in Fig. 17 of` the drawings. As the knob 68 is turned to release the latch bolt the finger 13 presses the pin 'M backward causing movement of the backstop 6I from behind the coin receiver 2l andinto a position of rest as shown in Fig. 9. Now, as the door is closed, the keeper being engaged by the beveled end of the latch bolt will force said .bolt 22 with its lug 55 backwardly, as' before described, moving the finger 52 against tension fof its spring, and when the latch bolt reaches a position to'register with the receiver the spring acting upon the finger 52 will force said ringer against-,the lug 55 on the bolt thereby moving the latter into its locking position. In the final Vposition of the parts a lug 'l5 on the arm 28 will be forced `by the action of the spring 60 against a stop 'I6 projecting from the inner wall of the case, the receiver being thus located in its position of rest just out of line with the coin slot 24 and the finger 52 resting against the lug.55 on the latch bolt will provide a space just sufficient for the entry of a coin between the receiver and said inger.

When the receiver is in its position of rest the stop 5l is located opposite the' edge of the receiver just at one side of the notch 68, thus dog-` ging movement of the receiver from this position. After, however, the door has been opened and the coin has. been released the receiver occupies a position a slight distance forward of that just described. To dog the movement of the receiver forwardly from this position a stop 'l1 in the forni of a shoulder at the end of the lever 58 is provided andthis will prevent forward movement of the receiver from the position shown in Fig. 7. l

To guard against a sticking of the coin within the receiver 2l an ejector 18 in the form of a prong extending from one side ofthe latch bolt, i

as shown in Fig. l0, is employed. Should the coin fail to drop from the receiver upon backward.

movement of the latch bolt 22 in the closing movement of the door, as hereinbefore described, the parts will return to the position shown in Fig. 7. This, however, will be ineilective to prevent repeated functioning of the device. Therefore the ejector 'i8 is provided and when the knob 69 is operated to release the latch bolt the ybackward movement of the latter will engagethe ngerv with the coin and force it from the V`receiver.

j It will be noted that there are four stops to 'position the coin receiver, the stop 'I6 to prevent backward mo-vement by the spring t@ from its normalposition of rest,the back stop 6l to determine its position during a cycle of operations of the lock, the front stop 5l to prevent forward movement of saidreceiver from its position of rest, and the front stop 'll to prevent its forward movement after a cycle of operations has vcommenced.

In orderjto determine the'number of times lthe door isopened 'by the use of a rcoin a register 7S is employed locatedl at the top of the casing and observable through a window 8i) inthe side wall cated thereon, the disks-being operatively connected in afmanner well understood and for which reason, av detailed description isomitted herein, it

being sufcient to state that the disks `are operated as by means of a shaft 8l extending through one end of the register case that is supported upon a post 82 comprising a part of and rising from the-bracket 30, as shown in Fig. 9 of the drawings. A register operating arm 83 is secured at 'one end to the shaft 8| `and. is pivotally connected at its opposite end with a register operating link 84, said link being pivotally attached to one end of the actuating lever 66, as shown in Fig. 9 of the drawings.

From this description it will be seen that each time the lever 66 is operated byforward movement of the receiver 2l with a coin therein, in theoperation of opening the door, the register 19 will bev operated to denote such movement of parts.

In order to aid the movement of the coins from the shelf 49 into the coin box the latch bolt 22 is cut away on one side forming a downwardly inclined chute 85, see Fig. 9, along which the coins pass in their movement from said shelf.

The coin boX is inserted through an opening in the bottom of the case and is held in place by means of a locking bolt 8B operated in any ordinary manner by mechanism within the lock case 81 as by means of a key inserted through an'escutcheon 88A in the front of the case 20 in a manner that will be readily understood.

. A bolt stop 39 is formed on the bracket 30 in the path of movement of the dog 45 secured to the spindle 29, as shown in Fig. 10. This dog engaging the shoulder @6 on the latch bolt limits its movement under the influence of the spring 54 when said dog strikes the bolt stop 89.

In the event that a slug or washer with a hole through the center is attempted to be employed, which devices may be readily obtained, the action is illustrated in Figs. 20 and 21 in which it will be noted that when the slug passes into the receiver it will momentarily be hung upon the end of the finger 52, and this being curved to the proper degree, the slug will immediately pass off from the end of the iinger and downwardly along the shelf 49 into the coin box under the actionl of gravity. l

The latch bolt 22 has a stop 90 adapted to engage the edge of an opening 30 through the bracket 3Q hereinbefore described, in the form as herein shown-this stop being located at the rear end of a rib 9i the forward end of which rib constitutes the shoulder 46. The stop limits rearward movement of the latch bolt and the stop 89 limits its forward movement.

. In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.
