To all whom it may concern: 9

Be it known that I, CHARLES E. MORRIS, a citizen of the United States of America, and a resident of Lane, Franklin county, Kansas, have invented certain new and useful Improvements in Check-Controlled Apparatus. of which the following is a specification. The main objects of this-invention are to provide an improved form of check controlled apparatus adapted to be differently opera ed by coins of different denominations; to provide improved mechanism of this class which will operate so that a coin of one denomination will permit of a differoutnumber of operations of the machine to which the apparatus is applied than will be permitted by a coin of another denomination: to provide improved means for locking the apparatus against operation except when a coin has been inserted therein; to provide improved means for preventing the manipulation of the operating lever so as to permit of more than a certain predetermined number of operations for each coin of any particiilar denomination; to provide improved means for discriminating betweenthe difierent denominations of coins and causing correspondingly dili'erent operations for each when inserted into the same coin slot; to provide improved means for preventing a coin from being inserted into the apparatus except when all of thcpa'rts are in their normal initial position of rest ready for the receipt of such coin. These objects are accomplished by the device shown in the accompanying drawings in which I Figure is an elevation, partly broken away of a coin controlled mechanism constructed according to this invention and adapted to permit of a single operation of the machine (of which it forms a part) for each coin of a certain denomination and to permit of a plurality of operations of the machine for each coin of a certain difi'erent (.lenomimition. Fig. 2 is a sectional detail of the coin receiving pocket showing the position of its parts when supporting a coin of the larger size, and showing the relation oi" its dogs with the trip star which releases the larger coin after a predetermined number of operations of the machine. Fig. 3 is a. corresponding view showing the position of the parts at the instant after such coin of larger denomination is released and is resting in the bottom of the pocket. Fig. 4 is a section of the coin pocket on the line 4-4: of Fig. 1, showing also the latch which locks the coin pocket against downward movement except when a coin is seated therein. Fig. 5 is a detail showing in plan the relation of the trip star and one of the dogs of the coin pocket. Fig. 6 is a detail showing the controlling pawl and its dog in their relative positions for preventing an upward movement of the operating lever. Fig. 7 is a view similar to Fig. 6 showing the same parts in position for preventing a downward movement of said lever. Fig. 8 is an elevation partly brokenaway of the pawl 20 and some of the adjacent parts which cooperate therewith, the same being shown as viewed from the left of Fig. 1.

In the drawings, the machine to which the coin controlled apparatus is applied, is in-- dicated by a part of its casing 1 and by the operating member or lever 9. The coin chute is indicated 10, the end at which the com is inserted being opposed to a slot in the casing at 11. In the construction shown,

the operating lever. 9 is pivoted at 12 and is' provided with a handle 13 extendin outward through a slot in the casing. 'Tlie operating lever 9 is connected with the mechanism of the machine by a link 14. Rigid on the operating. lever is a rack 15 having a series of rack teeth 16 arranged in the arc of a circle concentric with the pivot 12 of said lever. The opposite edge 17 of said rack is a cam surface whose function will hereinafter appear. The movement of the lever 9 in either direction is controlled by ratchet means comprising-said rack and a double-toothed pawl 18 which is pivoted on the supporting frame. The tooth 20 of the pawl 18 is suitably located to engage the teeth of the rack and prevent a downward movement-of the lever 19. A second tooth 21 of the pawl 18 is suitably located to engage the rack teeth 16 and. prevent an upward movement of said lever. The pawl 18 is also provided with an arm 22 by means of which said pawl may be swung on its pivot for throwing either of the teeth 20'or 21 into mesh with the rack teeth 16.

A dog 23, pivotally mounted at 24 on the supporting frame, is normally urged into engagement with the pawl 18 by means of a spring 25, said dog being adapted to yieldingly urge either of the teeth 20 or 21 into engagement with the rack teeth 16 as is illustrated in Figs. 6 and 7. When the; tooth 21 isurged into engagement with the rack, the

dog 23 hooks over the point 26 of the pawl 18 as in Fig. 6 and yieldingly holdssaid tooth 21 into contact with the rack. Similarly when the tooth is in engagement with the rack, the dog 23 engages the pawl 18 as in Fig. 7. When the lever 9 is in its normal initial position as in Fig. 1, it engages the tail 60 of the dog 23 and lifts said dogout of engagement with the pawl 18 so 1that said pawl may be freely shifted by the actuating member 27 as will hereinafter appear.

The actuating member 27 is in the form of a counterpoised arm provided with a coin pocket 28 at its end, located so as to lie in alinement with the coin chute 10 when the arm 27 is in the position shown in Fig.1

' and serving as a seat for supporting a coin discharged from said chute. The arm 27 is provided with a counterweight 29 which is of. suitable form and disposition with respect to the pivot 19' to tend to hold the arm 27 either in the position shown by the full lines in Fi 1 or in the position shown by the dotted lines in said figure. The distribution of weight in the arm 27 is such that a 4 coin of suitable weight seated in the pocket 28 will cause the arm 27 to swing down to the position shown by dotted lines in Fig. 1. A latch pawl 30 is pivotally mounted on the supporting" frame, and is adapted to fall by gravity into the recess 31 in the pocket, and secure the arm 27 against being swung, as by a blow onthe casing, when no coin is seated in the pocket 28; When a coin is seated in the pocket 28, the latch 30 will be pushed out, as indicated by dotted-lines in Fig. 4, so as to permit the arm 27 to swing freely, The pocket 28 has an opening 33 in its edge, which is away from the pivot 19,

; so that a coin may roll out when the arm 27 I is in the lowered position. A wall 34 disposed along the ath of the pocket 28 reve'nts a coin rom accidentally fal ing through the opening 83 except when the pocket is near its lowest position. The arm 27 is provided with two studs 35 and 36, 1 which are spaced apart and located at rebeen swung the full length of its downward stroke. When the lever 9 has reached the downward limit of its stroke, a lug 37 on the rear face of the rack 15 en 'a'ges the arm 22, and swings the pawl 18 back to its initial position, as in Fig. 7. During the downward movement of the operating lever 9,

the cam surface 17 of the rack engages a stud 38 on the counterweight 29, and swings the arm 27 upward. The movement of the arm 2T under the action of the cam 17 upon theipin 38 is comparatively slow as compared. with the rate of movement of the arm 9. When the stud 37 comes into contact with the arm 220i the pawl 18 it causes said arm to engage the stud 36 and quickly force the arm 27 upward to its normal initial 'posit-ion. The purpose ofthis peculiar movement of the arm 27 will hereinafter appear. In order to prevent the arm 27 from again descending until the operatin lever 9 has returnedto its normal initia position, a latch pawl 39 is loosely mounted on the stud 24 and arranged so as to fall by gravity into engagement with a stud 40 on the arm 27 to prevent said downward movement of the arm 27. The pawl 39 has a tail 41, which extends downward so as to be engaged by the lever 9, and lift the pawl 39 out of engagement with the stud 40, as in Fig. 1, when the lever 9 is in its uppermost position, thus leaving the arm 27 free to swing through the weight of a coin.

The slot in the casing through which the lever 9' extends is protected by a slotted guide tube 42, within which is slidably mounted a second tube 43', through which the lever 9 extends. The slot in the tube 43 is of just suliicient length to allow the necessary lay of the lever 9, and said tube 43 slides a ong the tube 42 when the lever 9 is swung. The lever .9 is normally urged toward its u per position by a spring 44, which in the orm shown is a compression spring located within the telescoping tubes 42 and 43.

The mechanism by means of which a coin of one denomination is caused to operate the machine a plurality of times, while a coin of a second denomination will operate it but once, is constructed as follows:The pocket 28 has pivotally mounted therein two dogs 45 and 46. The dog 46 is normally urged to the position shown in Fig. 2 by a spring 49, and the dog 45 normally falls by gravity to the position shown in 'Fig. 3, its inner arm 47 extending into the path of a coin entering the pocket, and its outer arm 48 being retracted. The coin is indicated at 50 in Figs. 2 and 3. When the dog 46 is in its normal positiom-as in Fig. 2, its inwardly'extending arm 51 extends to such position that a coin of the smaller denomination, as for in; stance a one cent piece, will pass between arm 51 and shoulder 52, and rest in the bottom of the pocket, while a coin of a larger denomination, for instance, a five cent piece, will be supported between the arm 51 and the shoulder 52, as in Fig. 2, and, while being supported between the arm 51 and the shoulder 52, prevents the pawl 45 from swinging to the position shown in Fig. 3. The pawl 46 and shoulder 52 operateas erases selecting means to discriminate between coins of two difierent denominations. The discrimination between different denomina tions is determined by the diflerent physical properties or measurements of the coins. In the form shown the particular measurement which determines the selection is the size of the coin. A counting star or trip 53 is join naled on the supporting frame in such position that its teeth may be engaged by the dogs 45 and 46 when in their extended positions. The dog 45 is adapted to engage each of the teeth of the star 53 while the dog 46 is offset so as to clear all of the teeth except the tooth 54, which is thicker than the others. The star 53 is yieldingly held against rotation by the spring 55, which insures that the star 53 turns one tooth space at each operation. 'The dog 45 swings on its pivot during the downward movement of the arm 27, and therefore rotates the star only during each upward stroke. The pawl 46 is normally in its extended position, but it does not operate the star except when the thick tooth 54 is in position for being engaged by the dog 46. The spring 55 is of greater strength than the spring 49, so that it will not permit the pawl as to rot ate the star wheel 58 until said pawl 46 has ie'leased the coin and come into contact with the stop 62. v A

An arm 56 is pivotally mounted at 47 near the coin chute, and has a lug 58 extending into a slot 59 in the coin chute. The arm 56 normally hangs in such position as to allow a coin to be freely inserted}? into the coin chute, but when the lever 27iis swung down the counterweight 29 engages the arm 56, as shown by the dotted line in Fi 1, and moves the lug 58 across the path of coins in the coin chute, so as to prevent a coin from entering said chute except when the arm 27 is in its normal initial position.

The device which is herein shown is intended to be operated by coins of two difierent denominations, and the coin chute 10 is provided with an opening 62, through which are rejected all coins of lesser diameter than that of the smaller coin which will operate the machine. These coins are urged toward the opening 62 in any usual manner, as, for instance, by means of a spring 63. A slide 64 is mounted at the opening 62, and is adjustable across said opening to suit the diameter of said smaller denomination of coin. If it is desired to set the machine so i as" to reject the said smaller denomination, and operate only under coinsof the larger denomination, then the slide may be retracted so as to enlarge the opening 62, and'permit only coins of the larger denomination to pass.

The latch 65 provides an additional safeguard against. fraud by wrongfully manipulating the operating lever 9. This latch pawl 18 comprises a bent lever pivotally mounted on the supporting frame, and having-a hookshaped arm 66 extending into position for engaging a stud 67 on the arm when said arm is in its normal initial position. The

latch 65 also has an arm 68 extending-into 7 position for being engaged by stud 38 on the member 27. The arm 68 is so located with respect to said stud that said fllm'wlll not be engaged by said stud until the ocket 28 has been lowered sufficiently to disc urge the coin therefrom. After the arm 27 has been lowered sufiiciently to discharge the coin it has a continued downward movement, due to the fact that its center of gravity has passed over the other side of its pivot, and this continued movement causes the stud 38 to swing the latch 65 and release the arm 9.

The operation of the device shown is as follows: When a one-cent coin is inserted into the coin chute, on falling into the pocket, it passes between the shoulder 52 and the arm 51,- and falls into the lower part of the pocket, being retained therein, as illustrated in Fig. the pocket lifts the latch 30 and overbalances the arm 27, so that said arm-swings down under the Weight of the coin, to ,the position shown by the dotted lines inFi 1. When the arm 27 swings down, the em 86 engages the arm 22 of the pawl 18, and rocks said pawl to the positlon shown in Fig. 6. The lever is now free to be; swung downward, and as soon as it has passed clear ofthe tail 60 of the dog 23, said dog swings into engagement with the point 26 of the pawl 18, as in Fig. 6, and yieldingly holds the tooth intocontact with the rack. The

n w-" ermits a downward movement of the lfterfltl, but prevents a return movement. 'As the lever 9 swings downward, the cain surface 17 engages the stud 88, and slowly swings the arm 27 upward. As the arm 9 approaches the lower limit of its movement, the lug 37 on the rack 15 engages the arm 22, pushes it into contact. with the 2. The coin within stud 36, and swings the arm 27 to its initial position. This movement carries the pawl .18 to the position shown in Fig. 7, tripping the point 26 out of the notch 61, and causing the dog 23 to engage the pawl 18 in the manner shown in Fig. 7 so as to urge the tooth 20 into engagement with the rack. T he arm 9 is now free to return to its normal initial position under the action of the spring 44;, but is prevented from being depressed after a partial return movement by I stud 38 against the latch arm68; and thereby releases the arm 9. Upon the return of the parts to theirnormal initial position, the latch 30 prevents the arm 27 from again descending, and the pawl 18, being held inthe position of Fig. 1 by the stud 35, looks the operating lever 9 against downward movement until a new coin has been inserted into the coin chute to permit a second operation. When a five cent coin is inserted into the coin chute it lifts the outer arm of the dog 45 to its extended position, and is supported between the shoulder 52 and the arm 51-01 the dog 46 in the position shown in Fig. 2. The normal initial position of I the star 53 is that shown in Fig. 1; that is,

the point 54 stands in the position there shown: The dog 46, therefore, passes the star without rotating it except under the s ecial condition which will be hereinafter d scribed. When the arm '27 swings downward, while a five cent piece is supported by the do 46 as in Fig. 2, the dog 45 swings upward t rou h contact with said star, but

immediately alls to its extended position, so as to engage a tooth of the star and rotate it during the next upward movement of the arm 27. As the coin is held between the dog 46 and the shoulder 52, it cannot fallout when the arm 27 is in its lowered position, and it therefore remains inthe pocket 28. As soon as the arm 27 swings back to its initial position, as hereinbefore described in reference to the operation of the device with a one centfpiece, the stud passes into the notch 61 of the latch pawl 39, and the arm 27 is thereby held against downward movement until the arm 9 returns to its initial position. On

returning to its initial position the arm 9 engages the tail 41 of the latch 39, and lifts said latch out of engagement with the stud 40, as in Fig. 1. The weight of the coin in the pocket 28 thereupon causes the arm 27 to immediately swing down to its I lower position releasing the pawl 18, and

't-ates the star 53 one tooth space.

passing the star engages the tooth preceding the tooth-54, and carries the tooth 54 into the position in which it is'shown in Figs. 2 and 3'. The dog 46 then engages said tooth 54, and swings the star another tooth space, leaving it in its normal initial position, as in Fig. 1. On engaging the tooth 54 of the star, the dog 46.is first swung against the action of the spring 49 sufiiciently to release the coin 50 and allow it to fall into the bottom of the pocket, as illustrated in Fig. 3.

The stud 62 prevents further movement of the dog 46, and thereby insures the rotation of the star, as hereinbefore stated. On the next downward movement of the arm 27 the coin is discharged through the opening 33,. ,so that the device will look after the fifth operation of the machine. To change the number of operations which will be permitted for a five cent piece, it is merely necessary to substitute for the star 53 another having a different number of teeth. The.

to cause the first part of the upward move-- ment of the arm 27 to be sufficiently slow to give time for the perfect action of the star wheel 53 in releasing the five cent coin, thus preventing the possibility of a fraudulent manipulation of the operating lever, so as to cause the coin to be thrown upward slightly from its position' in the pocket, so that it would again become seated in the position of Fig. 2 after the action of the star, which would normally trip it from that seat. During the greater part of the downward swing of the arm 9, cam 17 gradually shifts stud 38 so that the arm 27 rises slowly, until it is past the star wheel 53, giving ample time for the proper action of the dogs 45 and 46 upon the star. After the arm 27 is past the star wheel the lug 37 comes'into contact .with the arm 22 of the pawl 18, forcing said arm 22 into engagement with the stud 36, and causing the arm 27 to quickly complete the remainder of its upward mpvement.
