MECHANICAL MOVEMENT FOR A TIMER Filed Aug. 51, 1960 5 Sheets$heet 5 [HZEZYfUfE Joe Bowman Rte/Lara fi ara m United States Patent 3,186,245 MECHANICAL MOVEMENT FOR A TIMER Joe Bowman, Greentown, Ind, and Richard H. Jordan,

Mansfield, Ohio, assignors to Kingston Products Corporation, Kokomo, Ind., a corporation of Indiana Filed Aug. 31, 1960, Ser. No. 53,151 19 Claims. (Cl.74-128) This invention relates generally to timers, such as may be used to control coin-operated laundry machines, and more specifically to improved coordinating structure incorporated therein which renders the timer assembly responsive to a plurality of manual movements, such as may be obtained by insertion of a plurality of coin successively in the coin mechanism thereof.

Although the principles of the present invention may be included in various devices, a particularly useful application is made in a timer of the type that is employed with a coin mechanism, whereby a plurality of coins must be successively inserted therein to initiate the operation of the timer, which thereafter completes a program, such as the operation of a dry cleaning machine.

Mechanisms have previously been provided by which a timer is rendered responsive to the insertion of a coin in a coin mechanism. Ordinarily, only a single coin is needed to place such mechanism in operation, and a coin mechanism is employed of a size which accommodates the desired denomination of coin. Thus a quarter, a half-dollar, or the like may be employed to initiate machine operation. Where two coins have been needed, such as two dimes or two quarters, it has been known heretofore to provide two coin mechanisms mechanically coupled together, and when both such ganged coin mechanisms are released by insertion of coins therein, they coact as a single mechanism to initiate operation of the device.

With the advent of inflation, the need for two coins has become more prevalent, and it is apparent that the use of two or more ganged coin mechanisms raises the cost of the resulting structure considerably, multiplies the amount of mechanism which might malfunction, increases the panel space required to support the coin mechanism, and the like.

Where operation ofa dry cleaning machine is to be initiated in response to operation of a coin mechanism, several larger denomination coins will be needed, for example three or four quarters. Under these conditions, duplication of coin mechanisms to accommodate large denomination coins for that type of operation becomes bur ensome, ineificient, and expensive.

In accordance with the principles of the instant invention, there is provided a novel coordinating or drive mechanism for the timer assembly itself which is responsive to movement of an external actuating member, such as may be carried by a coin mechanism. The novel coordinating mechanism of this invention is responsive to a plurality of movements of the actuating member in such manner that a preselected number of such movement are required to initiate timer operation. Stated otherwise, in a device of the type described where the instant invention is provided, a quarter may be inserted in the coin mechanism and the coin mechanism operated.

The novel coordinating mechanism is responsive to such operation and mechanically remembers that one coin has been apparently inserted. Such operation is repeated until a preselected number of operations has occurred, for example three, the third coin then being effective to initiate operation of the timer control mechanism.

Accordingly, it is an object of the present invention to provide a novel angular drive mechanism.

Another object of the present invention is to provide a novel connecting and coordinating means for a timer,

, A ice by which the timer is rendered responsive to an external actuating force.

Yet another object of the present invention is to provide a drive mechanism for a timer assembly such that the drive mechanism will set the timer in a starting position only after a predetermined number of actuations of said drive mechanism.

A still further object of the present invention is to provide coordinating means for acting between a coin-receiving mechanism and a timer mechanism to be controlled thereby, such coordinating mechanism being responsive to a plurality of operations of the coin mechanism to initiate timer operation.

-Many other advantages, features and additional objects of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which preferred structural embodiments incorporating the principles of the present invention are shown by way of illustrative example.

As shown in the drawings:

The principles of this invention are particularly useful when embodied in a coin-operated timer device assembly 11 such as shown in FIGURE '1. The device 11 includes a rugged case 12 which supports a conventional coin mechanism 13 having a manually operated slide 14 in which a single coin is received.

The device 11 further includes a timer assembly 15 driven by a motor 16 supported thereon. The timer 15 is secured to the case 12 by any convenient means. The details of the timer mechanism 15 do not form a part of the instant invention and the timer preferably includes an output shaft 17, herein also referred to as a function control shaft, which is rotatable by the motor 16 in the direction indicated by the arrow in FIGURE 1. An example of the timer 15 is shown in the United States patent to Constantine No. 2,703,347. In timers of this type, the shaft is rotatable for 360. A series of cam operated switches are provided to control the program of the device to which the timer 15 is electrically connected. The timer is so internally Wired that when the shaft 17 reaches a predetermined position, referred to as a finish position, power to the motor 16 is interrupted. To restart the timer, it is necessary that the shaft 17 be advanced in the same direction to a starting position at which'the motor circuit is reestablished, and from which position the timer 15 will be operated by the motor 16 to the finish position.

Since the motor 16 is powered through one of the switches within the timer 15, it can be seen that the total duration of the timing program is partly dependent on the angular distance that the shaft 17 is initially manually advanced at the start of the program. Therefore, the angu lar distance between the starting and the finishing positions of the shaft 1'7 is less than 360. The shaft 17 of the timer mechanism is disposed in offset relation to the path in which the operating means or slide member 14 of the coin mechanism 13 may move.

To connect the movements of the coin mechanism slide 14 with the timer shaft 17, and to coordinate the initial manual movement of the shaft 17 with the movements of the member 14, there is provided a one-way angular drive mechanism generally indicated at 18 in FIGURE 1, and shown in enlarged detail in FIGURE 2.

As seen in FIGURES 1 and 6, there is provided a drive means or actuating member 19, here comprising a drive arm connected to the slide 14- and reciprocable therewith in a path, the drive arm 19 having a cam surface 20 directed in the direction of reciprocation. The cam surface 2% is illustrated herein as being generally arcuate and concentric with the shaft 17 of the timer 15.

As best seen in FIGURES 2 and 3, the drive mechanism 18 includes a shaft 21 rotatably mounted at one end on a bracket arm 22, the shaft 21 being supported at its opposite end by a connector means 24 which in turn is rotatably supported by a bracket arm 23. A setscrew 25 renders the shaft 21 and the connector means 24 corotatable, while a slot and pin arrangement generally indicated at 26 renders the connector 24 and the shaft 17 corotatable. It is thus apparent that the shaft 21 could comprise an integral extension of the timer shaft 17. Thus the shaft 21 has a rotary drive connection with the device 15.

On the shaft 21, there is provided rotatably supported control means one portion of which is illustrated in this embodiment by a first rotatably supported means 27, and another portion of which is illustrated in this embodiment by a second or further rotatably supported means 28. The first rotatably supported means 27 includes two

members

29, 30, the member 29 being a radially extending portion which is disposed in the path of the drive arm 19. The member 29 thus comprises a support plate for a roller 31 which is engaged by the cam surface 20 of the drive arm 19. The other member 3 4 is a base plate which has a stop portion 32 engageable with a stop or abutment surface 33 on the bracket arm 22. The member is staked to a hub 34, there being a non-circular portion of the hub 34 extending through a non-circular opening in the member 3%. The member 29 may be angularly adjusted with respect to the member 3% by pivoting about the hub 34, and to this end is slotted as at 35 to receive a screw as for locking the members in a selected position. This adjustment is particularly useful for selecting or adjusting the length of the cam surface 2% which may engage the roller 31. A return spring 37 acts between the bracket arm 22 and the member 30 to bias the first rotatably supported means 27 in such direction that the stop portion 32 is normally engaged with the stop 33. Thus the means 27 normally is stationary and is disposed as shown in solid lines in the various figures. In some installations, the effective length of the slide 14 is quite substantial, and there is a danger that the drive arm 19 will slip off, namely radially outwardly of the roller 31. To avoid such an occurrence, there is provided, as best seen in FIGURE 1, a rigid guide 353 which is disposed adjacent to the roller 31, and which is slidably cngageable with the drive arm 19 to limit the amount which the drive arm may move radially away from the rotational axis of the means 27.

Referring again to FIGURE 1, it is now apparent that as the drive arm 19 is manually moved to the right, the cam surface 281 engages the roller 31 and effects rocking of the means 27 as a unit about the shaft 21 in the direction of rotation of the shaft 17, and effects further tensioning of the spring 37 which returns the means 27 when the drive arm 19 is retracted. Thus the rotatably supported means 27 may be rockably driven in response to manual movement of the drive arm 19. FIGURE 6 illustrates the movement of the drive arm 19 to the right by which the roller 31 is engaged by the cam surface 20 and rocked with the means 27 on the shaft 21. The surface 29 which is directed toward the roller 31 includes a straight portion 20a which extends parallel to the direction of movement of the actuating member 19. Once the raight portion 20a is engaged by the roller 31, as shown in broken lines in FIGURE 6, the means 27 is rocked no further. However, the straight portion Ztla allows increased, variable, or excess travel of the coin slide 14 to occur without causing further angular advancement or rocking of the means 27, since the portion 20:: holds the roller 31 in the position shown.

In like manner the second or further rotatably supported means 23 is supported on the shaft 21 and to this end includes two

members

39, 49 carried on a hub 41. The member 39 has a non-circular opening corresponding to a non-circular portion of the hub 4-1 of like configuration, the member 39 and the hub 41 being staked together for corotation. The member 4t) is rotatable about the hub 41 and is secured by a screw 42 to the member 39 for corotation about the axis of the shaft 21. To this end the screw 42 is received in one of a number of holes 43, the particular hole 43 used being selected to determine the relative angular relationship between the members 39 and 4% for a purpose presently to be explained.

The member 39 has a plurality of peripherally disposed abutments 44, best seen in FIGURES 4 and 5. Means are provided which act on the means 2d to prevent a reverse rotation thereof, namely to prevent a rotation opposite to that of the shaft 17, such means in the embodiment comprising a resilient blade 45 which is successively engageable with the various abutments 4 5.

The member 30 of the normally stationary means 27 is provided with a resiliently yieldable indexing finger 4-6, best seen in FIGURES 4 and 5, the finger 46 comprising, in this embodiment, a portion of a bell crank pivotally secured as at 47 to the member 30, a spring 48a providing a bias for pivoting the finger 46 about its pivotal axis and toward the periphery of the member 39. Each rocking movement of the normally stationary portion 27 includes an increment in the direction of the arrow in FIGURE 4, which thus causes a like movement of the second supported means 28 which includes the member 39, the member 39 thus being advanced in a single direction by the indexing finger 46 acting on one of the abutments 44, the rocking of the means 27 thus effecting an angular inrement of one-way movement of the means 28.

A predetermined one of the angular movements of the means 28 is transmitted to the shaft 21 by means of a lost motion connection. As best seen in FIGURE 2, the lost motion connection includes a shoulder 48 illustrated as being an integral portion of the member 3?, and a shoulder 49 illustrated as being an integral portion of the member 4%. Between the

shoulders

48 and 49, there projects a radially extending member 5%, here illustrated as being a pin corotatably carried by the connector means 24. Each of the

shoulders

48 and 49 is radially offset from the axis of the shaft 17 and extends in a generally axial direction. Thus the

shoulders

48, 49, and the pin 5% coact to provide an angular lost motion connection between the means 28 and the shaft 117. The angular amount of such lost motion is determined by the angular distance between the

shoulders

43 and 49, within which the pin St) is disposed. This space or angle may be adjusted by repositioning the screw 42 into one of the other holes 43.

Normal rotation of the shaft 17 by the motor 16 causes the pin 5-9 to engage the shoulder 48 and to rotate the means 28 with the timer mechanism 15'. A spring 51 acts between a point which is corotatable with the timer, illustrated as being the pin 59, and a second point which is corotatable with the second means 28, here illustrated as being the axial projection from the member 39 on which projection the shoulder 43 is located. The spring 51 thus biases the pin 56 into engagement with the shoulder 43.

When the second means 23 is advanced an increment by the means 27 as already described, the shaft 17 and pin 50 remain stationary, but the means 23, including both

shoulders

43 and 49, rotate by a like angular amount, thereby placing further bias on the spring 51, without effecting rotation of the shaft 17, the resistance to movement thereof being obtained from the timer 15.. When the drive arm 19 is retracted, the spring blade .45 acting on one of the abutments 44 maintains the angular increment of movement which has been imparted to the means 23 so that the means 23 does not return. If the mechanism is to be so adjusted that one coin will start the timer, the shoulder 49 is reset so as to minimize the gap between the

shoulders

48 and 49. However, the invention is used to best advantage when the gap between the

shoulders

48 and 49 is equivalent to a plurality of angular increments so that the second, third, fourth etc. coin must be inserted, or so that the second, third, fourth etc. movement of the drive arm 19 must be imparted before the shoulder 49 engages the pin 5th to drive the same in the direction of normal shaft rotation with sufiicient force to overcome the internal mechanical resistance in the timer 15, thereby advancing the timer to its start position.

Thus the angular lost motion means or connection between the rotatable means 28 and the shaft 17 ultimately effects a driving rotational engagement therebetween, but does so only after a predetermined number of rocking movements of the first means 27 which effects a like number of angular increments of movement of the means 28. Thus the various abutments 44. are spaced about the rotational axis by an angle with respect to each other which is less than that of the effective angle of the lost motion connection, by which each increment of angular movement of the means 2% is less than the angle of the angular lost motion connection.

It is to be understood that the details by which this invention has been disclosed are exemplary, and that the invention may be embodied in other structures. Referring to FIGURES 7 and 8, a slightly modified form of the instant invention is disclosed. in these figures an angular drive mechanism 52 includes a shaft 53 rotatably supported at one end in a bracket 54 and having a connector means 55 at the other end thereof which is rotatably supported in a bracket arm 56, the connector means 55 being corotatably coupled to the timer shaft 17 as described before. A first rotatably supported means 57 includes two members 53, 59, one of which is staked to a hub 69, and the other of which is adjustable with respect thereto by means of a screw and slot arrangement 61. The member 59 has a radially extending portion on which a roller 31 is carried for cooperation with the drive arm 19 as already described. The member 59 also has an indexing finger d2 pivoted at 63 thereto and which finger 62 is re siliently biased by a spring 64 into peripheral engagement with one of a series of abutments 65. The spring 64 is secured at its other end to a portion of the member 59, and the means 57 as a whole is resiliently biased by an additional spring which acts between the means d7 and a portionof the bracket which has been removed for clarity of illustration. The member 58 includes a stop portion 67 which is engageable with a stop as forming a part of the bracket 54-.

The mechanism 52 further includes a second rotatably supported means 69 including a member 70 having the abutments 65 and a second member 71 adjustably secured thereto by screw means 72. The members 7i) and 71 are respectively provided with

shoulders

73, 74 between which a pin 75 is disposed to form an angular lost motion connection between the means 69 and the shaft 17, the pin 75 being corotatably secured to the connector means 55. A spring 76 acts between an ear 77 on the member 70 and a point corotatable with the shaft 17. Reverse rotation of the means 69 is precluded by means of a spring blade 78, the distal end of which is successively engageable with the various abutments 65.

The operation of this embodiment is substantially the same as that which has already been described. By means of the adjustment locked by the screw 61 the relation between the roller 31 and the drive arm 19 may be established. It will be noted that the indexing finger 62 thus also is adjusted, whereas in the earlier described embodiment, the corresponding indexing finger is carried by the member which has the stop portion. The structure, function, and adjustment of the means 69, including the lost motion connection, is substantially identical to that illustrated in the first embodiment.

, Referring now to FTGURES 9 and 10, there is shown an additional embodiment of the invention, which differs from the previously described embodiments primarily in that the adjustment features have been omitted, and that the indexing finger is not pivotably supported. By the omission of these features, a somewhat simplified form of the invention is provided, generally indicated by the numeral 79. This embodiment also includes a rotatable shaft 80 supported at one end by a bracket 31 for rotation, and at the other end by the timer shaft 17 acting through connector means 82 which is pinned to the shaft 80 by a pin 83 forming a part of the lost motion connection. The mechanism 79 includes a first rotatably supported means generally indicated at 84-, which is reelable on the shaft 80, and a second or further rotatably supported means 85 which likewise is rotatably supported on the shaft 8t), and which has an angular lost motion connection therewith.

As best seen in FIGURE 9, the first rotatably supported means 84 has two portions, one of which is indicated by the numeral 86 which supports the roller 31 in radially extending relation to the shaft St), and the other of which is indicated by the numeral 87 which is a stop portion which engages a stationary stop 88. Bending of the stop 88 atfords a degree of roller adjustment. A return spring 89 biases the means 84 into engagement with the stationary stop 88. The roller supporting portion 86 and the stop portion 87 form a part of a n1ember 90 which is secured to a hub 91, which is held in position between a shoulder on the shaft 39 and a snap ring 92. A resiliently yieldable indexing finger 93 is riveted as at 94 to the member 90, one end of the finger 93, indicated at 95, being bent over to prevent angular movement about the rivet 94, and the other end, indicated by the numeral 96, being engageable with each of a series of abutments 97 on the second rotatably supported means 85. The end 96 of the indexing finger 93 yields in an axial direction in response to the next abutment 97 when the finger 93 is being returned by the spring 89.

The second or further rotatably supported means 85 includes a member 93 having a series of peripheral abutments 99 engageable by a blade spring 109 to maintain the angular position of the rotatably supported means 85 during return rocking of the first rotatably supported means 84. The member 100 is secured as by staking, to one end of a hub 191, a stop plate 102 being secured as by staking to the other end thereof. The stop plate Hi2 has a pair of axially directed or extending projections which jointly define a pair of

shoulders

103, 104 between which the pin 83 is received to define the lost motion connection between the means 85 and the shaft 80. A spring 1% acts between a point corotatable with the timer shaft 17, namely the pin 83, and a point corotatable with the means 85, namely an ear 107 on the member 98. Thus the means 85 includes portions comprising abutments for indexing, and other portions which define shoulders. The extensions which define the shoulders may be bent to afford a degree of adjustment. Since the shoulders N3 and 194 are corotatable with respect to the member 98, it is apparent that either or both of the shoulders 103, 104- could be integral therewith as shown in FIGURE 5. However, there is an advantage to having at least one of the shoulders 163, 104 on the separate member or plate M2. It is apparent from the two preceding embodiments that abutments 9'7, 99 may be provided in greater quantity than that illustrated in FIGURE 9. It is also apparent that the degree of adjustment to be afforded by bending the fingers which carry the shoulders 103, 164 would not be sufficient to alter the number of rocking actuations of the first rotatably supported means 84 needed to initiate angular movement of the shaft 17. Thus in the manufacture of this device, it is advantageous that the member 98 be provided with a substantial number of abutments for subsequent asembly with any one of several stop plates 162 which have an included angle, or which provide with the member 98 an included angle, of such magnitude as to render the desired number of abutments usable.

The operation of this embodiment is thus similar to that already described.
