5 claims. (ci. rsi-1s) This invention relates to coin collectors and particularly to those collectors where the deposit of more than .one coin is required for obtaincertain services from the instrument. As applied to telephone coin collectors, one object of the invention is to provide a collector arranged to require the deposit of two or more coins of the same or different denomination before the collector may be utilized.

In the usual type of telephone coin collector a deposited nickel passes down a coin chute into a coin hopper where it strikes a coin trigger and temporarily comes to rest upon a cointrap as shown, for example, in the O. F. Forsberg UL S. Patent 1,043,219. The actuation of the coin trigger serves to close certain contacts which for a manual system signal the operator and which for a machine switching system prepare apparatus at the central oflce to permit the dialing of a local call. l

In the preferred form of this invention the arrangement is such that a nickel and a penny must be deposited before the operator will be signaled or before a local call may be dialed. Mounted upon the coin chute or upon the coin hopper are interlocking latches projecting into the nickel runway and the penny runway to hold either coin in the runway until the other coin has been deposited, whereupon both coins will be released to-actuate the usual coin trigger to cause the collector to be available for service in the usual manner. A relay is provided in the talking circuit portion of the substation to be energized when talking current is applied over the line to the substation to actuate means for holding the latches in coin freeing position but when the talking battery at the central oiice is disconnected from the substation the relay is deenergized to restore the latches to their normal interlocking engagement. Thus, the interlocking latches are arranged to require the deposit of two coins for obtaining a connnection to the central office but once the connection is estabblished, placing talking battery on the line, the latches are disengaged to permit the subsequent passsage ofanother coin which, for example, may be depositedin payment for an overtime period of conversation.

Referring to Fig. l the front view of a telephone coin collector 22 is disclosed having the usual transmitter 23 and calling dial 24 mounted on the front wallof the upper housing 25, and extending from one side of the upper housing is the usual switchhook 26 for receiver 2l. Mounted on top of the upper housing is a coin gauge 28 for receiving quarters, dimes and nickels while on the right side of the upper housing is a separate coin gauge 29 for receiving pennies. Below the upper housing 25 is the usual lower housing 30 containing a cash compartment and a refund chute opening.

Referring more particularly to Figs. 3 and 4 it will be seen that theupper housing contains a multiple coin chute 3| which in general is similar to the multiple coin chute disclosd in Forsberg Patent 1,043,219. The coin chute as disclosed more clearly in the sectional view of Fig. 10 comprises flve spaced plates 32 to 36, inclusive, between which lie the suitably formed coin runways. A coin channel for nickels is provided between rear plate 32 and intermediate plate 33 whereby a nickel deposited in gauge 28 follows the line marked 5 path, strikes the upper edge of bell 31 and after being temporarily restrained by finger 38 falls into coin hopper 39. A penny deposited in gauge 29 follows a coin channel between intermediate Dlates 33 and 34 indicated by line marked 1 path, strikes the upper edge of bell 48 and after being temporarily restrained by a pivoted finger 4| drops into coin hopper 39. A dime deposited in the dime Opening of coin gauge 28 follows a coin channel between intermediate plates 34 and 35 indicated by line marked 10c path, strikes both the upper and the lower edges of bell 31 and then drops into the coin hopper. A quarter deposited in the quarter opening of coin gauge 28 follows a coin channel between intermediate plate 35 and front plate 36 indicated by the line marked 25;!I path, strikes gong 42 and drops into coin hopper 39. Also mounted upon the 'rear wall 32 of the coin chute is an electromagnet 43 for controlling the pivoted fingers 38 and 4| in a manner to be described later. Any coin reaching coin hopper 38 strikes a coin trigger 44 and in the manner described in the Forsberg patent closes contacts 63, thereby 'establishing circuit to ground through the windings of the coin relay 45, whereby apparatus at the central ofce will be suitably 'conditioned and the deposited money subsequently collected or refunded by the operation of relay 45.

The pivoted coin operated fingers 38 and 4| are shown in various stages of their operation in Figs. 5 to 9, inclusive. It will be noted from Fig. 10 that the nickel finger 38 has a projection 46 which extends through slot 41 in chute wall 32 and into a slot in chute wall 33 so that projection 46 normally obstructs the passage of coins in the nickel runway. It will also be noted from Fig. 11 that the penny finger 4| has a projection 48 passing through slot 49 in chute wall 32 through a slot in chute wall 33 and into a slot in chute Wall 34 whereby projection 48 normally obstructs the passageof coins in both the nickel runway-and the penny runway.

Referring particularly to Fig. 5 a portion of the coin chute is shown with the end walls of the nickel runway indicated by the dotted lines 58 and 5|. The path of a first deposited nickel is shown by line marked 5 path Where the nickel 52 drops between partition 531 and end wall 50 and strikes projection 46 of finger 38 where it is temporarily prevented from proceeding down the chute. Finger 38 is pivoted at the point 54 and is normally biased by counterweight 55 to have projection 46 lie adjacent the upper end of slot 41 as shown in Fig. 6. The force of nickel 52 in striking projection 46 causes finger 38 to move counterclockwise a short distance until its shoulder 55 strikes extension 51 of finger 4| whereupon the nickel 52 is held in the runway above projection 46 until the penny finger 4| has been moved about its pivoting axis 58. to an extent suiiicient to free shoulder 56 of extension 51.

39 actuate a If it is assumedthat a penny only has been deposited without a nickel, the penny path adjacent the pivoted nger 4| is shown in' Fig. 6. Finger 4| due to counterweight 59 is biased to have its projection 48 normally lying adjacent the upper end of slot 49 as shown in Fig. 5 but when the penny 68 is deposited and strikes projection 48 of finger 4|, finger 4| is moved slightly counter-clockwise until shoulder 6| on finger 4| strikes shoulder 62 on finger 38, whereby the penny is held in the runway above projection 48 until the nickel finger 38 has been moved counter-clockwise to an extent sufficient to free shoulder 6| of shoulder 62. It will be seen from Fig. 5 that the deposit of a nickel causes finger 38 to move sufficiently to free shoulder 6| of shoulder 62 and it will be seen from Fig. 6 that the deposit of a penny is sufficient to move extension 51 out of the path of shoulder 56. Hence, when both a nickel and a penny are deposited in their respective runways the interlocking latches 38 and 4| are freed from each other and operate fully as shown in Fig. 7 to permit the passage of both coins down the chute into hopper 39.

Nickel finger 38 due to counterweight 55 and penny flnger 4| due to counterweight 59 after the passage of the coins as shown in Fig. 7 will tend to restore to their normal position of interlocking engagement to prevent a subsequently deposited penny or nickel from reaching the coin hopper 39. However, as previously stated, the coins 52 and 60 after reaching coin hopper coin trigger 44 to close contact 63 whereby in a well-known manner apparatus at the remote central oice connected to line 64 will be conditioned to permit the extension of the line to the called party desired and among other 4things talking battery will be applied to line `64 to energize the transmitter 23 and receiver 21.

It Will be noted from Fig. 2 that electromagnet 43 is connected in series with transmitter 23 and that the electromagnet 43 will be energized as soon as talking battery is connected to line 64 and will remain energized until the connections at the central office are broken to disconnect talking battery from the local substation. As shown in Figs. 5 to 9, inclusive, electromagnet 43 has an armature 65 pivoted at the point 66 and biased by spring 61. Armature 65 at its upper end has an arcuately formed arm 68 bearing on its under side a pin 89 projecting into a slot 18 in finger 38 and also has on its under side a pin 1| projecting into a slot 12 in finger 4|. With electromagnet 43 deenergized and with fingers 38 and 4| in the normal positions as shown in Fig. 3, pin 69 is adjacent the upper end of slot 18 and pin 1| is adjacent the upper end of slot 12. 'Ihese pins 69 and 1| do not interfere in any manner with the full actuation of fingers 38 and 4| when operated by a deposited nickel and penny as in Figs. 5, 6 and 7 since their counter-clockwise movement due to coin operation is conipleted before pins 69 and 1| contact with the lower ends of their respective slots 10 and 12. However, as soon as electromagnet 43 is energized its armature 65 is attracted upwardly and pins 69 and 1I contacting with the upper ends of slots 18 and 12 will move fingers 38 and 4| counter-clockwise to the positions shown in Fig. 9 where'the fingers are disengaged from each other and occupy non-obstructing positions for coin travel whereby a nickel alone or a penny alone may be deposited and freely passed by the fingers 38 and 4| to drop into hopper 39. When electromagnet 43 is deenergized by the' removal of 75 talking battery from the substation, spring 61 will restore armature 65 to itsnormal position of Fig. whereupon fingers 38 and 4| will be restored to their normal interlocking engagement by their respective counterweights.

The purpose of electromagnet 43 in controlling fingers 38 and 4| in the above manner is to enrable a single coin deposited, for example, in

payment of an .overtime charge to reach the coin trap 16 in hopper 38 without being held by finger 88 or 4|. It is also obvious that if a toll call is desired from the substation shown, the deposit of both a nickel and a penny would first be needed to call the operator, which nickel and penny would,then be refunded, whereupon the subscriber would deposit the proper amount for the toll call, which amount may include, for example, a nickel, a dime and a quarter. Without the control by electromagnet 43 this nickel would be blocked in the coin chute by iinger 38 and could not be collected at the completion of the call.

Figs. 5, 6 and 7 show how the pivoted fingers 38 and 48 are released by the deposit of a nickel and a penny. Fig. 8 shows how the same result can be obtained by the deposit of two nickels. In Fig. 8 the first deposited nickel 13 is held in the chute 'between partition 53 and end wall 58 against projection 46 of nickel finger 38 since iinger 38 is not free to rotate to coin freeing position due to extension 51 being in the pathof shoulder 56. When a second nickel 14 is deposited, the second nickel after striking the top of the rst nickel rolls off the first nickel over the top of partition 53 into a portion of the nickel runway between partition 53 and end wall 5|, thereby by-passing the nickel finger 38 but striking the penny finger 4| which as shown in Fig. 11 projects into both the nickel and the penny runways. The second nickel in operating finger 4| performs the same function as described above for a deposited penny whereby fingers 38 and 4| are released from each other to allow both nickels to drop onto the coin trap 16 in coin hopper 38 after actuating the coin trigger 44.

As described above with respect to Figs. 10 and 11 pivoted fingers 38 and 4| do not project into the dime runway or the quarter runway. Hence, a deposited dime or quarter is not restrained in the coin chute but freely passes into hopper 38 to reach coin trap 16.

The. form of the invention shown in Figs. l2 to 21, inclusive, is quite similar to that above described except that the interlocking iingers and associated electromagnet are mounted on the coin hopper instead of the coin chute.

Coins deposited in the quarter, dime and nickel coin gauge 88 or in the penny gauge 8| traverse coin channels in the upper housing 82 similar to those above described except, as shown in Fig. 12, the outlet for the nickel channel is at the left portion of the chute assembly 19, the outlet for -the penny channel is in the central portion of the chute assembly, and the .dime and quarter outlets are at the right of the chute assembly. Therefore, as shown in Fig. deposited nickels will fall into coin hopper 83 between side wall 84 and partition 85 andwill be held in the coin channel between side wall 84 and partition 86 due to pivoted finger 81 which has a projection 88 normally occupying a coin obstructing position in the described channel. Finger 81 is suitably pivoted on a'rod 88 and when projection 88 is struck by a deposited nickel the finger 81 as shown in Fig. 14 will move counter-clockwise a small amount until its arm v88 contacts with extension 8| of the penny nger 82 whereby the deposited nickel is held inthe channel above 'projection 88 until the penny finger has been actuated to move its extension 8| out of the path oi' arm 88.

A deposited penny will enter the hopper in the coin channel between partition 85 and partition 83 to strike projection 84. of the penny finger which is suitably pivoted on pin 85. A penny in striking projection y84 will move the finger 92 clockwise until shoulder 86 strikes portion 81 of the nickel finger, assuming that the nickel finger is in normal position. However, the deposit of a nickel moves arm 81 downwardly far enough to free shoulder 86 of portion 81, thereby allowing the penny finger 82 to complete its movement to penny releasing position; and the initial movement of penny finger 82 due to a deposited penny is sumcient to move arm 8| out of the path of projection 88, thereby allowing the nickel finger 81 to complete its movement to nickel releasing condition. Hence, when both a penny and a nickel are received in rthe coin hopper both coins will be release'd to actuate coin trigger 98 and come to rest on coin trap 88 where they may be subsequently collected or refunded under the control of coin relay |88 in the usual manner.

The pivoted fingers 81 and 82 have been de- 187,640, filed January 29, 1938, to which refer-- ence may be made for a more detailed description.

Fig. 14 is an end view of the coin hopper showing both fingers 81 and 82 in their normal positions obstructing the passage of either a nickel or a penny until the other coin has also been deposited. Fig. 15 is a front'view of the coin hopper showing both iingers 81 and 82 in their normal positions. Fig. 16 shows the position of the nickel finger 81 when only a nickel |8| has been deposited without a penny. Fig. 1'7 shows the position of the penny linger 82 when only a penny |82 and not a nickel has been deposited. Fig. 18 shows the operation of both fingers 81 and 82 to coin freeing position when both the nickel |8| and the penny |82 have been deposited.

Fig. 19 shows how both 4ngers 81 and 82 may be freed of their interlocking engagement by the deposit of two nickels where the first nickel |83 is temporarily held by projection 88 of the nickel finger and the second nickel |84 after reaching the coin hopper will roll off the first nickel through the opening between partitions 85 and 86 to enter the penny channel and cause the actuation of the penny finger projection 84 whereby both coins will be released to proceed on down the coin chute to operate the coin trigger 88 and come to rest on coin trap 88.

However, the coin hopper arrangement of these figures differs from that in the above-mentioned Hoyt application in that there is mounted on the coin hopper 83 an electromagnet |85 which performs the same function as electromagnet 43 in the earlier figures, it being assumed that the winding of electromagnet |85 is in series with the transmitter as shown for electromagnet 43 in the circuit diagram of Fig. 2. The armature of relay |85 is pivoted at the point |86 and has a forked extension |81 between the prongs of which' lies an angular projection of a wire or rod |88. Wire |88 extends upwardly through a slot in the mount- 75 ing bracket |09 and as shown in Fig. 15 its horizontal portion ||0 due to armature biasing spring ill normally lies just below portion H2 of the penny finger 92 while portion H3 of wire |08 normally lies just below portion 81 of the nickel ringer as shown in Fig. 14. Wire |08 also has an extension H5 freely passing through a slot in bracket |09. As soon as talking current is applied to the substation from the central oiilce electromagnet |05 is energized to attract its armature, thereby lifting Wire |08 from the position in F'ig. l5 to the position shown in Figs. 20 and 21, whereby-the two pivoted fingers 87 and 92 are moved suiciently to free each other from their interlocking engagement. Therefore, as long as talking battery is applied to the substation a nickel will freely pass by the nickel finger 81 and a penny will freely pass by the penny ilnger 92. Hence, any coin or coins deposited after the initial deposit will not be held up by the pivoted fingers B1 or 92 but will reach the coin trap 99 without delay to be subsequently collected or refunded depending upon the current applied to the coin relay |00. It will be noted that dimes or quarters will enter the coin hopper between partition 93 and end wall IIB and without any interference will proceed down the hopper and come to rest on coin trap 99.

In the above arrangements it has been convenient to describe them as applicable to United States coins of certain denominations but'it will be readily understood that the invention may be applied to the control of coins; or tokens of any denomination or size.
