This invention relates to sound producing mechanisms which are responsive to key set motor actuated devices such as a cash register for example and has forits object to provide an improved device of this class.
Another vobject is to provide a sound producing mechanism capable of calling out any desired monetary value without the necessity of a separate key for each sound or value.
Referring to the drawings- Fig. 1 is a wiring diagram of the key controlled switches.
Fig. 2 illustrates the sound producing records.

Dishonesty of a sales clerk in ringing up the value of a purchase in a cash register may be minimized if a sound producing mechanism simultaneously notifies the purchaser of the value registered. Prior suggestions for such devices haven, required too many keys, especially in 30, amounts ending in the teens. Another objection has been the necessity for pressing keys in the desired sequence, not always an easy matter fora hurried clerk. According to this invention lno separate keys 85 are needec' for the teens and the keys may be pressed in any sequence or simultaneously, yet the emitted sounds are properly timed.
For purposes of illustration this invention is shown applied for cash register keys for recording any amount from $.01 to $9.99 by the use of the usual twenty-seven keys, though of course the invention is applicable to key actuated devices having a more or'less number of keys.
l In Fig. l are shown switches actuated by three rows of keys, those on the left being responsive to\ the units or cents key's, the central ones being actuated by the dimes column keys and those on the right responsive to the keys of the dollars column. Of course the dollars actuated keys may be placed on the left and the cents ou the right,
. if desired, without affecting this invention. Current is supplied from the busbars I0 and II. An additional switch part I2 is responsive to an extra-key located preferably at the bottom of the M. machine which must be pressed after the numbered key or keys have been actuated. On pressing this extra key the switch part I2 bridges the gap between the switch elements I 3 closing Athe circuit through the electric motorl I4 which drives the sound producingv mechanism and timingv de- 5. vice of this invention.
If the lower key of the right hand column is numbered to designate one dollar, then pressing this key causes the switch part I5 to bridge the gap illustrated below it closing the circuit until 10 after the sound mechanism has operated. After closingthe motorcircuit the switch I 6 of the timing mechanism closes the circuit through the magnet I1 at the proper time to cause a stylus to engage the sound mechanism. After closing the $1.00 key and actuating the lower key for switch part I2, the circuit is from the bus I0 through the wires I8, I9 and 20, switches I5, I6, magnet I1,wire 23, switch I2 and I3 to the' bus I I, as well as actuating the` motor by current 20 flowing from the wire I9 through the motor and the switch I2, I3.
If the third key from the bottom in the middie column be numbered "3 to indicate 30 then on pressing this key the switch 2I is closed. After 25 the motor has turned the timing device the switch 2 IA is later closed completing the circuit through the electromagnet ZIB and current then flows from the wire I9 through the switch 2|, switch 2IA, magnet ZIB to the wire 22 `which is con- 30 nected as illustrated to the wire 23. If both the $1.00 key and the 30 key are simultaneously depressed the timing device closes the switch I6 to causev the $1.00 sound toA be emitted before closing the switch ZIA to emit the 30 sound, as will be 35 described hereinafter in connection with the timing device.
Assuming the fifth key from' the bottom of the left column is numbered for 5, then on depressing this key both the switch parts 24 and 25 are 40 depressed, switch part 24 opening the circuit from the contacts above it and closing the circuit through the contacts below it. Assuming that only this 5cA key is depressed and no other monetary key actuated at the same time, then 4I the circuit will be from the wire I8, I9, through the switch part 26 (to be described later), the wire 28, the contacts below vthe switch part 2|, switch 24A, magnetluB, wires 29 and 23 and switch I2 and I3 as before. The 10 key of the 50 middle column depresses two switch parts 28 and 21. If the 10 key and the 5 key are depressed` substantially simultaneously then the circuit is through the wire I8, switchpart 21 closing the contacts below it, wire 30 through the contacts 55 -to the bus II.
In Fig. 2 is shown the layout of the drive mechanism from the motor I4 through the gears 3| to the timing device 32 and the sound records 33 and 34. Adjacent each record'are a plurality of arms 35, each carrying a stylus 36, as shown in Fig. 3'. Beneath each arm is a magnet 31 .containing a winding as illustrated in conection with Fig. 1. On'actuation of the magnet 31 its arma.- ture 38 is depressed against the action of the spring 39 allowing the ann 35 to rest by gravity.
with the stylus upon the sound record. The travel of each stylus along the sound record is comparatively short and for the desired purpose each arm is pivoted at 40 to allow this limited travel.
lOrl the underside of each arm,35 is an arcuate or cam surface 4I vas shown in Fig. 4 resting on a roller 42 carried by the armature 38 so .that when the magnet hasr been deenergize'd the spring 39 raises the armature 38 and arm 35 to disengage the stylus from the sound record. 'Ihis cam surface 4I causes the arm 35 to be slightly rotated about its pivot 40 due to gravity in order Vthat 4the stylus .3G may be returned to its original Aor startingP position with respect tothe sound record.
vThe timing-device 32 is shownin Fig.- 5 as being comprised of a number of segments each of which is adapted to bridge a pair of brushes. The segments IE Jare each for closing the circuit through some one 4of the dollar switches. The segments numbered ZIA are each for the dimes and those numbered 24A` and 25A for the cents. The nine `segments 24A are for the cents. Nine other segments 25A include the teen cents, that is for the cents when actuated in combination with the l0 key. A-segment 26A is for the 10c key. l
At the right -end of the timer is a short segment 4S which controls the cash register motor. As is usual the cash register motor records the amount of thesale and also releases the depressed keys. The last and long segment 41 closes the circuit through the loud speaker.
In Fig. 6 brushes 48 and 49 are arranged for each of the segments so that while the segment bridges .these brushes the circuit through them is closed. The angular extent of the segment and the spacing of the brushes .control the duration' of time that `the .circuiti is closed through the particular electromagnet which actuates some one of the several Styli.
There are altogether thirty six arms 35 and Styli for theapparatus illustrated.4 The dollar segments I6 are in advance Yof the dime segments 2IA in order that the dollars may be called out by the appropriate sound record before actuation Iof the desired sound record for the dimes column. The segments 24A,. 26A and 25A being arranged still later cause the cents to be called out after the dollars and dimes.
In Fig. 'Tis illustrated one of the unit or cents keys of a' cash register mounted 0n a stem 50 to which is attached a horizontal member 5I preferably of insulating material carrying the switch parts 24 and 25. Beneath each of these switch parts are the contacts 52 and 53 adapted to be bridged by the conductor bars 24 and 25. Above only one of the contacts are the bridging contacts adapted to be closed when the key is in normal position as was described above in connection with the operation of the 5 key.
Fig. 8 is a side view of Fig. 7 and shows the switch parts attached to the keys of an existing cash register whereby the entire sound producing mechanism may be made as an attachment for cash registers'. All of the arms 35 are connected in parallel with thefloud speaker 54v as shown in Fig. 9 so that after the speaker segment l 41 has been closed and any one of the arms 35 actuated, the sound produced is electrically transcribed by the speaker 54.
The separate key actuating the switch I2 must be depressed after the other key or keys have been actuated since the circuit is not closed until this master key is depressed. The use of this separate key controlling the switch I2 and I3 enables one of the keys in each of the columns to bevdepressed in any sequence so long as all are depressed `before the control key I2 closes the circuit through the switch I2, I3.
If the wrong key in any column Ais depressed, then as is customary in cash registers and the like, it is only necessary to depress the correct key when the iirst or incorrectly operated key will be automatically raised without affecting the sound producing mechanism since the delay action or control switch I2 is not closed until the other keys have been correctly operated.
An especially noteworthy feature of this invention is the provision of two sound producing records for each of the unit keys whereby'it is unnecessary to increase the number of keys by having a separate key for each of the teens. The timing Amechanism is believed to be a noteworthy feature since it ensures-the correct timing'of the sounds from the dollars record, the l through the motor I4, the timer 32 of the sound records 33 andr 34 are all set in motion, By the time the desired dollar segment has been bridged by its brushes the sound records will have gained their normal speed. Since the register motor,
which is in addition to the motor I4, is controlled by the segment 46, it Will be understood that all of the keys, including the control key, are releasedY by the registermotor breaking the circuit through the motor I4 and stopping the rotation of the timer and sound records.
On again closing the circuit and starting the motor I4 the timer may rotate a substantial angular `distance while the sound records are attaining their desired speed and before any of the segments illustrated bridge their brushes, due to the angular location of the segments in the approximate manner illustrated. The device illustrated is for use primarily with cash registers of the type in which the depressed keys are held down until they are released by the register mechanism.
While the apparatus has been described using two motors, one for the timer and sound records and the other for the register, it will be understood that one motor may be used to take the place of these two. Where one motor is used it4 means also including means responsive to the powould be started by the control key and stopped bythe timer and instead of having the segment 46 start a separate motor this segment would control an electromagnet clutch to start the desired mechanism in operation from the already operating m'otor. Oi' course this last expedient is of interest principally with new registersto be manui'actured, while the layout described is adapted to be applied as an attachment to existing registers. v
In the drawings-it will be understood that switches not numbered and described specicalrect number resulting fromcombining any unit key with any tens key, means controlling the first means and including at least two vcircuits controlled by each of the unit keys, and means responsive to -the position of the tenskey numbered 1 for selecting either one of the two circuits controlled by the unit key which is actuated.
2. The combination with a key controlled mechanism including a number of unit keys numbered between 1 and 9, and tens keys numbered between 1 and 9, of means for audibly calling the correct number resulting from combining any unit key with any tens key, means controlling the first means and including at least two circuits controlled by each of the unit keys, said second sition fof the tens key numbered 1 for selecting` either one of the Atwo circuits controlled by the n unit key which is actuated, said second means further including a pair'of switches actuated by each unit key, each switch controlling one of said vtwo circuits, one of said two circuits for each unit key passing through a. switch closed by the tens key numbered 1 when in normal position, the
' other circuit for each unit key .passing through record and controlled by the selected circuit.
3. In combination a key controlled mechanism,
including a plurality of unit keys, a plurality of pivotal arms, a plurality of sound records, and each arm carrying a stylus adapted to cooperate with one of said records, at least .one tens key numbered 1, three switches controlled by each of said keys, one of each set of three being closed when its key is in normal unactuated position,
two of each set of three switches being closed l when its key is actuated, each switch of eachv and a unit key are actuated approximately together a. third circuit is closed through switches closed by both keys, each of said key controlled circuits effecting cooperation of one of said pivotal -arms and lits stylus with one of the sound records.
