12 Claims.

This invention relates to a selective coin parking meter, and more particularly to improvements in the meter disclosed in the McGay et a1. Patent No. 2,168,302, dated August 1, 1939.

One of the objects of the invention is to broaden the usefulness of the mechanism disclosed in said patent, so that two denominations of coins of different diameters may be inserted in the same coin entrance slot, and the mechanism will act on the inserted coins in a manner to select and give time value in proportion to the'money value of the coins. With particular reference to a parking meter, the machine may be adjusted so that the insertion of a nickel will obtain the full length parking period ofan hour, whereas the insertion of a penny will secure one-fifth of the full parking period or twelve minutes. Obviously, any two coins of different diameters may be used in combination as above.

Another object of the invention is to furnish a means for by-passing the coin of lesser denomination when the time remaining on the meter is equal to or greater than the time obtainable by the use of such coin. On the by-passing operation, the coin of lesser denomination is allowed to pass through the mechanism and is disposed of as may be required without affecting the operation of the machine. I

With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a front elevation of the mechanism with certain parts omitted tofacilitate illustration, and with the elements in the normal position which they occupy before a coin is inserted in the machine.

Fig. 2 is a front elevation of the rear coin guide plate and showing the shift lever which it carries, in normal position.

Fig. 3 is similar to Fig. 1, but showing the elements in the position they occupy after a nickel has been inserted and the indicating hand has been moved to the sixty-minute position on the time scale but before other elements of the mechanism have returned to normal position.

Fig. 4 is a view similar to Fig. 3, but with parts omitted so as to more clearly illustrate the operation of other parts.

the position of the starter lever just after a coin has been inserted.

Fig. 6 is a view like Fig. 3, but showing the position of certain parts after a penny has been inserted and the indicating hand has been moved to the twelve-minute point on the time scale.

Referring to the drawings, l0 designates the case of a clock-work (not shown), to drive a shaft H in a counter-clockwise direction. Such shaft, by means of a friction connection 12, turns a time indicator or hand IS in a counterclockwise direction. However, due to the friction connection (not shown) the hand l3 can be turned clockwise on shaft H while the latter is turning in an opposite direction or is stationary. The parts ID to l3 inclusive, may be like similar parts in the above-mentioned patent.

The clock-work (as in said patent) also intermittently drives a shaft [4 which completes a revolution rapidly upon the insertion of a coin into a coin guideway 15b, partly shown in Fig. 2. The guideway is arranged between a rear plate l5 and a front plate 16, secured to the front of the case it! by any suitable means such asscrews I531. The rear plate, as best shown in Fig. 2, has a forwardly projecting integral tongue l5a and a flat embossed portion I52, and the edge I511 of the tongue defines one side of the guideway. The opposite side of the guideway is defined by pins l5c projecting forwardly from the plate l5. In other words, the parts l5, I511, I50 and I6 (as in the above-mentioned patent) form a narrow chute down which a coin may be passed to control the actuation of the mechanism.

The clock mechanism, which rotates the shafts II and I4, is controlled by a brake (not shown) actuated by a rock shaft I'l (Figs. 4, 5 and 6) which is pivotally supported by the case It) and is fixedly connected to the upper end of a starter lever l8. The latter controls the starting of the shaft I 4 by releasing the brake, and the lever is provided at its lower end with a pin l9 which extends through the lever and projects both forwardly and rearwardly therefrom. The rearwardly projecting portion of this pin acts as a stop and cooperates with a notch 20 in the edge of a lock cam 2| that is arranged between'the parts Ill and I5 and is oscillatable about a pin or axle 22 projecting. forwardly from the case ID. The forwardly projecting portion of the pin lflextends through the slot of plate l5 into the coin guideway.

Fig. 5 is a view similar to Fig. i, and showing on When a coin 23 or 23a (Fig. 5) is inserted and -wardly projecting reset pin 3|.

gravitates down the coin chute, the edge of the coin will engage the forwardly projecting portion of the pin l9 so as to move the starter lever l8 in a clockwise direction. Obviously, this will result in movement of the rear portion of the pin |9 out of the notch 20, and, therefore, the lever l8 will release the brake of the shaft |4 so that the clock-work will turn such shaft in a clockwise direction. This will cause a wheel 24 fixed to shaft H to turn in the same direction and move a link 25 (pivotally connected to the parts 24 and 2|) toward the right, as will be clear from Figs. 4 and 6. This results in shifting the cam 2| in a counter-clockwise direction about its stationary Supporting axle 22. This movement causes a pin 26 (projecting rearwardly from one end of the cam 2|) to push a link 21 toward the left. The link 21 is provided with a slot 50 for connecting the pin 26 with the link 21. The pin 26 is adapted to travel in the slot 50 for a purpose as will be hereinafter described. The link is pivotally connected to a reset plate 28 (turnably mounted on the shaft so that the reset plate will be shifted in a clockwise direction on the shaft from the position shown in Fig. l to the position shown in Fig. 3, assuming that a nickel was inserted in the coin slot.

The reset plate is of quadrant shape and provided at its curved edge with holes 29 calibrated to correspond with the calibrations on a time scale or flag 38, and any one of these holes is adapted to receive the threaded shank of a for- Such pin, when the reset plate 28 is turned in a clockwise direction, engages the left edge of the time indicator l3, and moves the indicator to the point 60 on the flag 30, if a nickel is inserted in the machine, or to the point corresponding to twelve-minutes on the flag, in the event that a penny only is deposited. The parts 28 to 3| inclusive may be similar to like parts in said Patent No. 2,168,302.

With the parts as shown in Fig, 5, with a nickel 23 deposited, the wheel 24 will complete a cycle from its normal position shown in that figure. This will cause the corner 32 of the reset plate 28 to contact a flange 33 projecting forwardly from the flag 38, which flag is pivotally mounted at one end on an axle 34 extending forwardly from the case It). When the reset plate 28 moves the flag 38 in a counter-clockwise direction to the position shown in Fig. 3, and the pin 3| comes into engagement with the indicator 3, a lug 35 at the rear of the indicator will come into engagement with an arc-shaped forwardly projecting flange 36 at the lower edge of the flag, so that the indicator will function to support or hold the flag up after the reset plate 28 returns to normal position, due to the rotation of the wheel 24. Such plate is limited in its counterclockwise movements by an abutment or stop 31 (Fig. 1) which projects rearwardly from the plate l5.

It will be obvious that after the wheel 24 completes a cycle to lift the flag 30 and place the time indicator in proper position, the pin N of the starter lever l8 will again enter the notch 28 so as to put on the brake and stop the movement of the wheel 24.

When a nickel coin 23 is introduced into the coin guideway lb, it will come to rest with spaced points of its edge engaging respectively a forwardly projecting pin 38 on the lock cam 2|, and a forwardly projecting pin 39 on a lever 40. The pins 38 and 39 project through the slot 55 into the coin guideway so as to temporarily halt 78 the passage of a nickel through the chute. The lever 40 has its lower end pivotally connected at 4| to the rear of the coin guide plate l5 (Fig 2). A coil spring 42 cooperates with the lever 46 and normally holds the pin 39 in the position shown in Fig. 5.

The coin before coming to rest on pins 38 and 39, will act as a wedge and move the pin l9 (which extends into the coin chute) toward the left to actuate the lever i8.

At this point it will be noted that when a nickel is introduced and it comes to rest on the pins 38 and 39, its center will be above the turning axis 22 of the cam plate 2|. Consequently, as soon as the clock-work starts to move, the pin 38 will move counter-clockwise in an arc coinciding with the periphery of the nickel, and travel from a point below the horizontal diam eter of the nickel to a point close to the pin 39, so that the nickel will roll over pin 38 and drop into a position on a supporting lug 43, while the wheel 24 is completing a cycle. The lug 43 extends forwardly beneath the lower edge of the plate |5 into the lower end of the coin chute. Obviously, with a nickel deposited it will engage the pin l9, and push the starter lever 18 toward the left into position to release the brake and cause the wheel 24 to turn. As the wheel turns, the link 25 will turn the lock cam 2|, and the cam pin 26 will push on the link 21. Therefore, the link will first move the reset plate 28 in a clockwise direction so as to lift the flag 30 and move the indicator l3 around to the point where the indicator will coincide with the sixty-minute mark on the flag. Then the reset plate 28 will immediately be returned to normal position, and the pin l9 will again drop into the notch 28. During such cycle, the nickel is released from the pins 38 and 39, and drops on to the lug 43 which holds it until the next cycle of operation so that it may be seen through a window 44 in the front coin guide plate l6. On the next cyole of the machine, the lug 43 is moved in a clockwise direction so as to release the nickel and permit it to drop into a coin receptacle (not shown). This is accomplished in the following way. The lug 43 is integral with the lower end of a rocking lever 45 pivotally mounted at 46 on the front of the case I0, and caused, by a coil spring 41, to normally occupy the position shown in Fig. 5, that is, to engage an abutment 48 projecting from the front of the case ID. The lever has a rearwardly extending lug 49 at its upper end which is positioned to be engaged by the link 25 to cause rocking of the lever 45 during each cycle of the wheel 24. During such cycle, the lug 43 will move from a position beneath the coin to allow the coin to drop into the coin receptacle.

In order to permit a penny to be employed instead of a nickel in operating the machine, the pin 26 of the lock cam extends rearwardly into a substantially L-shaped slot 50 of the link 21, and such link is provided with a rearwardly extending pin 5| adapted to be engaged by the lever 4|! when the latter is moved in a clockwise directron. The lever 40 is provided with a hooked end portion. If the lever 48 is turned in a clockwise direction, it will engage and cause the pin 5| to shift the right end of the link 21 upwardly and bring the pin 26 into a position to move in the slot 50 lengthwise of the link 21, whereby when the lock cam 2| turns, it will not move the reset plate 28 to the position shown in Fig. 3, but only to the position shown in Fig. 6 because the pin 26 will move for a distance to the left in slot 59 before commencing to push link 21 toward the left. Consequently, the indicator l3 will be set for a twelve-minute operation, instead of a sixty-minute operation. The lever 5 40 is provided with a hooked portion at its free end in order to limit rotation of the lever 40 by contacting the-411g 5| of link 21.

This may be accomplished as follows: The front coin guide plate 16 carries a rocking lever 52 (shown in normal position in Fig. 1) pivotally mounted at 53 on the front of said plate and provided at one end with a rearwardly projecting lug 54 which extends through slots 55 across the coin chute into the path of movement of the cam 2|, and is normally held at the lower end. of an arc-shaped slot 55a of the plate l6 by means of a coil spring 52x (Fig. 3), surrounding the pin on which the lever rocks. The opposite end of the lever 52 has a forwardly extending lug 56 which at certain times is engaged by and cooperates with a cam 51 movable with the indicator l3, but arranged below the shaft ll. As best, shown in Fig. 3, when the indicator I3 is set for a sixty-minute operation, the cam 2| in turning will abut against the lug 54 and thus move lever 52 into the position shown, whereby the cam 51 will come into a position above the pin 56, and consequently, the stop lug 54 of the lever 52 (when cam 2| returns to its normal position, Fig. 5) will be held by cam 51 in such position as not to obstruct the coin guideway, while the indicator hand is moving from the sixty-minute point on the flag 39 to the twelve minute point on such flag. As soon as the indicator reaches this point, the cam 51 will release the pin 56, and then the coil spring which actuates the lever 52 will move it to the position shown in Fig. l, where the lug 54 will be so positioned in the coin guideway as to prevent a 40 penny from passing through the chute without actuating the mechanism. As long as the pin 56 is in engagement with the cam 51, the lug 54 will be positioned at one side of the coin chute so that if a penny is introduced after a nickel, it will simply be by-passed through the lower right-hand side of the coin chute and will not affeet the operation of the mechanism. It will be apparent that the penny will actuate the starter lever 19 but with the lever, 54 out of the way the penny and the pins 38 and 39 do not push on the lever 48 to cause any actuation of the reset plate.

The lever 52 is moved into in Fig. 3 by the-stop cam 2| each time the cam 55 operates. During such operation, the edge 21b of the cam engages the rearwardly extending lug 54 of the lever.

In reference to the operation ofthe machine by a penny instead of a nickel, it will be observed that a penny 230. (Fig. 5) is of smaller diameter than a nickel, so when inserted in the coin chute, it can pass between the pins'38 and 39, and come to rest on the lug 54, and in doing so, of course, it will push on the pin l9 so as to cause the starter lever l8 to release the brake. Then, as the mechanism starts its cycle, the pin 38, 'instead of moving along the edge of the coin as it does in the case of a nickel, presses against the left edge of the penny, and thereby forces the 7 pin 39 toward the right. This in turn causes the lever 48 to shift the right end of the link 21 upwardly so as to bring the slot 59 into such position that the pin 26 will travel along such slot during a portion of the cycle of the mechthe position shown anism without pushing on the link 21. This will be apparent from an inspection of Fig. 6. As soon, however, as the pin 26 reaches the inner end of the slot, it will push on the link and cause the reset plate to be moved to the position shown in that figure, and then, as the mechanism completes its cycle, the reset plate will be returned to the normal position shown in Fig. 5. During such cycle the cam 2| will engage the lug 54 so as to move it to a position from beneath the penny where it will release the penny and permit the latter to drop in the chute to a position where it will come to rest on the lug 43.

By way of recapitulation, it will be understood that the mechanism is released to operate by the size and weight of the coins inserted, which act upon the starter lever pin l9 to cause par tial rotation of said lever, and in turn, releases the reset gear train to operate. In Fig. 5, the nickel 23 is shown by dash lines, and a penny 23a is shown by dot and dash lines. Both coins are-of sufhcient diameter to act on the starter pin I9 to effect release of the reset mechanism. It should be noted that the coin only holds the starter lever in the released position, and immediately upon the starting of the reset action, thearcuate edge 2|a of the lock cam 2i comes into engagement with the pin l9 and holds the starter lever until the completion of the reset cycle, thus permitting the operative coin to pass on to the observation window 44 during the reset process.

While either coin will serve to release the reset mechanism to operate, the mechanism in turn operates upon the coin used in such manner as to give predetermined values in proportion to the monetary worth and size of the coin. As will be noted in Fig. 5. the nickel 23 acts to rotate the starter lever, and comes to rest on the shift lever pin 39 and the lock cam pin 38. These pins are so spaced that they will engage and hold the larger diameter coin at a pointbelow the diametrical line or the coin. Thus, due to the nickels position with respect to the pins, when the mechanism resets and the lock cam is rotated and its pin 38 pressed against the nickel, the nickel will tend to squeeze from between the two pins upon which it rests, and not tend to cause movement of the shift lever pin 39 (due to the heavy spring tension of 42 on the shift lever, and not squeezing the coin on a diametrical line) The spacing of the pins 38 and 39 is such that the smaller coin or penny will just pass between them. The coin stop 54 is in such position that it will support the smaller coin or penny so that the pins 38 and 39 are diametrically opposed in relation to the penny. Thus, when the reset operates with a penny in the operative position, the cam pin 38 acts upon the penny and tends to wedge the latter against the shift lever pin 39. At the beginning of the reset cycle, the action between the cam pin 38 and the shift pin 39 is on a diametrical line of the penny, and thus the shift lever 49 is partially rotated. Upon further movement of the lock cam pin 38, it moves from a dlametrical relation between the pin 38 and shift pin 39. and eventually allows the coin to squeeze out and pass on to the coin observa: tion window. This squeezing of the coin from between the pins does not take place, however, until the shift lever 49 has been moved to cause the selection of the smaller delivered value, for

the smaller denomination coin causes the shift lever 48 to be rotated. Obviously, the link 21 will be shifted so as to permit the pin 26 to move I eration. Such cam is'flxed to the time lengthwise of the slot 50 toward the reset plate 28, this resulting in a short stroke of the reset plate. The length of the slot 50 is such as to cause the short stroke of the reset plate to move the indicator I! to a time position on the flag 30 corresponding to the lesser value coin. In reference to by-passing a smaller denomination coin, it is apparent in connection with a parking meter that it may be desirable to cause a coin of smaller diameter to by-pass through the mechanism without causing it to function if the unexpired time on the meter is equal to or more than the time allotted for this coin. The chief purpose of this by-passing feature is to prevent the use of a slug which is of the size of the larger diameter coin, to set the meter for a full .period, and then the use of a penny immediately following, to clear the slug from the observation window, and thus remove the evidence of illegal operation. For this purpose, the coin stop lug 54 is made part of the oscillating lever 52 which can be shifted in and out of working position under the control of the lock cam 2| and the indicator cam 51. If the coin stop lever lug 54 is in the position shown in Fig. 3 or Fig. 6, the penny will pass between the pins 38 and 39 and on through the coin chute without causing the mechanism to function. The arcuate cam 51 is arranged to hold the lever 52 in the by-passing position for a period of time after a nickel opindicator l3 and may be arranged to permit the lever 52 to snap (by action of its control spring), into the coin holding position at any desired position of the indicator "hand. During resetting, the lever 52 is rotated to by-pass position by contact of its rearwardly extending lug 54 with the radial edge 2Ib of the lock cam 2i. This rotation of the by-pass lever permits engagement of the coin stop lever 52 with the arcuate cam 51.

It will be manifest that the mechanism may be employed with any suitable coin guide or chute which will be arranged between the slotted plates i5 and IS. The chute is preferably of the kind disclosed in the McGay et al. Patent No. 2,168,302.

The foregoing description and accompanying drawings disclose one construction in which the invention is embodied. Many other forms of construction can be used in practicing the invention. Furthermore, the invention may be employed on a wide. variety of apparatus. In ;the construction disclosed, the power for accomplishing the operation of the mechanism is secured from a power-storage spring (not shown), and

v this power is delivered through the drive wheel 24 to accomplish the reset operation and selective functioning of the mechanism. This same principle could be used on a mechanism designed to employ an outside operating force as the power means, such as a handle or lever.
