COIN-CONTROLLED LOCK.

Specification of Letters Patent.

Patented May 30,1922.

Application led October 29, 1920. Serial No. 420,338.

To all 11i/1,0m t may concern:

Be it known that I, DONALD C. MORGAN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Coin-Controlled Lock, of which the following is a specification.

It is the object of my invention to obtain certain desirablefeatures in coin-controlled locks, and to avoid certain diiculties frequently encountered. More particularly, its object is to prevent the release of the coin through which the lock is operated until the bolt is pushed back independently of the coin actuation, either by letting the door shut independently of the handle operation or by withdrawing the bolt by the inside handle; to avoid jamming by having the parts which engage the coin and actuate it or are actuated by it thicker than the coin slot, so that no open spaces are left into which a thin coin may slip; to make the device readily adjustable 'or coins of different diameters; to preventA the possibility of obtaining more than one actuation of the counter for each coin deposited; and to provide a separate actuator for the counter and for the slot closer, Which actuator is di rectly operated on by the vcoin so that the operation of the slot closer vand counter is not produced save` when a coin is deposited, and is then produced only once for that coin.

The accompanying drawings illustrate my invention: Fig. 1 is a vertical section through a lock embodying my invention, with the lower part in section and with the bolt partly broken away to show the interior slides, the parts being in normal posi tion with a coin in place; Fig. 2 is a fragmentary view corresponding to the upper part of Fig. 1, with the bolt pushed back by the outside handle; Fig. 3 is a fragmentary view similar to Fig. 2, but with the bolt released after having been operated by the outside handle, and also shows in dotted lines the position of the bolt and the releasing of the coin thereby when the bolt is shoved back in the normal shutting of the door; Fig. 4 'is a view similar to Fig. 2, but with the bolt withdrawn by the inside handle instead of by the outside handle; Fig. 5 is a vertical section on the line 5-5 of Fig. 1; and Fig. 6 is a horizontal section on the line 6-6 of Fig. 1. j

The lock casing 10 may be of any desired type, usually made of two parts, and has an enlarged lower part provided with a removable locked door 11, the removal of which gives access to the accumulatedcoins. Sultably mounted in the casing 10 near the top 1s a horizontally slidable bolt or latch 12, which co-operates with the usual strike 13 on thel door casing. The bolt 12 is suitably spr1ngpressed to latching position, as by a tension spring 9.

The bolt 12 is provided with a longitudinal slot 14 extending vertically through it throughout its entire intermediate portion, for receiving a suitable coin, the length of this slot being greater than the diameter of the largest size coin used plus the length of the bolt movement. Near one end this slot 14 is crossed by two pins 15 and 16 for co operating with the edge of the coin at one side. The slot 14 is in the same vertical plane with a slot 17 in a slot-closer 18 and with a slot 19 in the top of the casing 10, the slot-closer 18 being horizontally slidable above the bolt 12 between such bolt and the slot 19 so that a coin 20 may be deposited when the slot-closerI is in the position shown in Fig. 1 but cannot be deposited when it is in the position shown in Figs. 2 and 8.

The outside operating handle 21 is mounted on a shaft 22 which projects into the casing 10 and is there provided with two fingers 23 and 24. The finger 24 co-operates withan adjusting screw 25 in a fixed lug 26 on the inside of the casing for adjusting the normal position of the handle 21 and finger 23 to t the device to diii'erent coins, such as nickels, dimes and quarters, a tension spring 27 being connected to the shaft 22 to move it in a counter-clockwise direction (Fig. 1) to cause inter-engagement of the finger 24 with the end of thescrew 25. The finger 23 projects upward througli the slot 14 in the bolt 12, and through a similar slot in the front end of a cylindrical slide 28'slidably mounted in a central cylindrical hole 29 extending lengthwise from the rear of the bolt almost to the front thereor", a cross pin 30 extending across the slot in the slide 28 infront of the finger to cause the slide 28 and nger 23 to move together. The rear end of the slide 28 co-operates with the opposite edge of the coin 2O from the pin 15, the space between suoli slide and pin being adjusted by the screw 25 for different diameters of coins. Thus when a coin 20 is in place, caught between the slide 28 and the pin 15, the turning of the handle 21 causes the finger 23 to push the'slide 28 to the rear, and the slide 28 acts through the coin 2O on the pin 15 to push the bolt 12 to the rear, as indicated in Fig. 2; but when the handle 21 is released the springs 9 and 27 return these parts to their initial position (Fig. 1 or without permitting the coin 2O to drop out.

A second cylindrical slide 31 is mounted in the hole 29 behind the coin 20. The slides 28 and 31 are entirely independent of each other, save when the former acts on the latter when a coin is between them and the handle 21 is turned, under which conditions the coin 2O directly engages the slide 31 and forces it to the rear with the bolt'12. Two links 32 and 33 are pivotally connected to the rear end of the slide 31. The link 32 is connected to one end of a lever 34 the other end of which is connected by a link 35 to the slot closer 18, so that when the slide 31 is pushed to the rear with the bolt 12 the slot closer 18 is pushed forward to the position shown in Fig. 2 to prevent the insertion of a coin by reason of the displacement of the slot 17 from the slot 19.V

The link 33 is connected to one arm of a bell-crank 38 the other arm of which is connected by a link 37 to the operating arm 38 of a counter 39 which records the number of coins deposited. The second arm of the bell-crank 36 is also acted on by a tension spring` 40 which tends to move such bell-crank and its connected parts to a normal position, shown in Fig. 1, with the slide 31 forward. 1When the slide 31 is moved to the rear against the spring' 4() it not only moves the slot closer 18 forward but also actuates the counter 39 once.

The cylindrical hole 29 and the ' cylindrical slides 28 and 31 are of lgreater thickness (or diameter) than the slot 14, and project beyond the plane of such slot on both sides, so that a thin coin will not be able to slip between them to cause jamming of the parts.

The bell-crank 36 has an arc-shaped series of ratchet teeth 41, which co-operate with a spring-pressed pawl 42 to permit clockwise movement of the bell-crank and rearward iovement of the slide 31 but to prevent movement of such parts in the opposite direction. Thus when the slide 31 is pushed to the rear upon the deposit of a coin 20 and the manipulation of the handle 21, such movement is permitted by the pawl 42 and ratchet 41, but whether or not this movement is completed these parts are prevented from returning,` to their former position in case the handle 21 and bolt 12 are allowed to return to normal position. This makes it impossible to work the counter 39 a number of times upon the deposit of a single coin, as might otherwise be done. The pawl 42 has a downward extension 43, which may be acted'on bya cam 44 to release the pawl 42, whereupon the spring 4Q may return the parts 36, 31, and 18 to normal position. The cam 44 is carried by a shaft 45, on which the inside handle 46 is mounted and which is also provided at its front end with slots 47 through which it may be worked by a porters key. The shaft 45 is spring-pressed in a counter-clockwise direc- (Figs. 1 to 4 inclusive) by the same spring 27 which presses the shaft 22 in a counter-clockwise direction, such spring eX- tending between projections on said two shafts. The shaft 45 has an upwardly eX- tending nger 48 which co-operates with a downwardly extending finger 49 on the back end of the bolt 12 to withdraw the bolt when the shaft 45 is turned against its spring` 27.

ln operation, with the parts in the position shown in Fig. 1, a coin may be dropped in through the slots 19 and 17 to the position shown in such ligure, in which position it is caught by the cross pin 15 and the slide 28. ABy now turning the outside handle 21, the arm 23 acts through the slide 28 and the coin 2O to push back the bolt 12 and the slide 31,` bringing` the parts to the position shown in Fig. 2. This also moves the slot-closer 18 forward, and turns the bellcra-nk 3G in a clockwise direction to operate the counter 39 one step forward, as indicated in Fig. 2. The handle 21 may be turned back and forth as many times as desired, and the coin 20 remains in place between the slide 28 and the cross pin 15 so long as the bolt 12 is not pushed back independently of a movement of the handle 21, as indicated by F 2 and by the full lines in Fig. 3. This back-and-forth movement of the bolt and outside handle, however, has no effect on the counter 39 or on the slot closer 18 after the initial operation of such parts upon the first pushing back of the bolt. lVhen now the door is allowed to swing shut so that the bolt is pushed back by its co-operation with the strike 13, independently of any action of the outside handle 21, the parts are brought to the position shown in chain lines in Fig. 3, with the cross pin 15 moved away from the slide 28 to permit the coin 20 to drop from between them into the lower part of the casing; 10; but this still does not effect the slot closer 18 or the counter 19 because the pawl 42 co-operates with the ratchet 41 to hold these in the position into which they were moved upon the first pushing back of the bolt 12. V-,lhen now the shaft 45 is turned, either by the inside handle 46 or by a porters key co-operatingA with the slots 47, the Vlinger 48 acts on the finger 49 to withdraw the bolt 12, which withdrawal also serves to release the coin 20 and allow it to drop from between the cross pin 15 and slide 28 if the bolt has not been previously drawn back independently ot the outside handle 21. The operation of the shaft 45 not only withdraws the bolt 12, to permit opening ot the door, but also causes the cam 44 to act on the extension 43 to release the pawl 42 from the ratchet 4l and tion of a withdrawable bolt, an outside handle and a member operated thereby, said bolt being provided with a part between which and said member a coin may be supported to serve as a thrust member between said handle-operated member and said boltcarried part to withdraw the bolt upon operation of said outside handle, `a second member in position to be acted on by said supported coin when the bolt is so withdrawn, said second member and said bolt being otherwise movable independently of each other, a pawl-and-ratchet device for permitting only the coin-actuated movement of said second member, said second member being spring-pressed in the opposite direction, a slot closer and a counter operatively connected to said second member, and means for withdrawing said bolt independently of said outside handle and for releasing the pawl of said pawl-and-ratchet device to permit said second member -to return to normal position.
