DAVID W. RAYNOLDS AND PAUL J. SCHWARZHAUPT, OF SOOTIA, NEW YORK, ASSIGNOBS TO GENERAL ELECTRIC COMPANY, A CORPORATION OF NEW YORK SOUND. RECORDING APPARATUS Application filed larch 80,1980. Serial No. 437,521.
Our invention relates to phonograph sound recording ap aratus and particularly tosuch apparatus w ich is adapted to be used by the public and by which a person. may record aspoken message which may be transmltted, for example by mail, in lieu of a written letter. It is the object of our invention to provide an improved apparatus of the above mentioned character which -shall be reliable, efficient," convenient and simple to operate,
protected against theft of parts and misuse of the apparatus, and inexpensive to manufacture.
Our invention will be better understood f om the following description taken in conncction with the accompanying drawings and its scope willv be appended claims. I
Referring to the drawings Fig. 1 is 'aper spcctive view of the ,recor in mechanism involving our-invention; Fig; 218 a side view of the cabinet containing the recording mechanism with parts broken away; Fig. 3 is a perspective view of the booth which contains handle 14 has been released. The door may now be swung open and in so doing contacts.
the recording apparatus; and'llig'.i4 is a cuit diagram of the apparatus a? In Fig. 3 we have shown]; jreco apparatus enclosed in the. 1' whi constructed with sound proof walls and door;
The door 2 is spring-clomd and normally is.
locked in closed position. To gain entrance" to the booth. the door-is first'unlocked' elec trically by means to be described later and then is pulled open by the handle '3 thereon.
To open the door from the inside it is-provided with the handle 4, the turning of which operates the. latch 5. Within the booth is the, recording cabinet 6,. the microphone 7 into which the operator speaks and which-is adjustably suspended from the ceiling, the.- -hand switch 8 for controlling the starting and stopping of the recording. mechanism,
the signal lights 9 and 10, the dome light 11,
and the record blank vending machine 12.v
In this vending machine are a number of rec ord blanks adapted foruse with therecord- Eng apparatus, the machine being constructed to release one record blank each time that the proper coin is inserted in the slot 13 and the handle 14 operated. Vending machines pointed out in the of this characterare well known and there i I .against the xed contact 19. When the is closed the latch cannot be moved from the exterior of the booth and the .door can be unlocked only by a withdrawal of the catch 21. This member is pivotally mounted at 22 and is spring-pressed in the locking position. I
To move the catch to the unlocking position there is provided an electromagnet comprising the winding 23 and the core By closing of the circuit between s rings 17 and 18the magnet is energized an the catch is withdrawn from the etch 5. In so doing, contact s rings 25 are actuated to close a holding'clrcuit shunted about s ring 17 and 18 so as-to hold" the door unloc ed after the 27 and 28 mounted on the door are separated.
Since these contacts are in series with-the winding 23,. the catch thereby is released:
shaft'32 having therein a vibration absorbing coupling 33. On the u per end of shaft 32 is mounted the turntab e 34 upon which the record blank 35is adapted to be supported. Mounted on suitable guide rods 36 and 37 is the carriage 38 which supports the cutting stylus and which is moved slowly and uniformly in one direction by the motor 30.
For this purpose the carriage is provided with a half nut 40- mounted on a short shaft 41 having head 42 and having the spring 43 for normally pressing the nut into en agement with the screw 44. The latter orms a part of the horizontal shaft 45 which is connected by worm gearing 46 with shaft 32. Pivotally mounted on the upper portion of the carriage 38 is the lever 48 at one end of which is the electromagnetic stylus actuatmg member 49 and at the opposite end I of which is the cam 50. The carriage at a stylus are completely covered by the housing 57 which until the carriage is moved to its. initial position does not )ermit of the removal of the record blank. efore any return movement of the carriage is initiated the stylus must be lifted from the record-and the half nut must be withdrawn from the cooperating screw. To bring about these results we have provided the apparatus now to be described. Shaft 60 mounted on the carriage has at its lower end the bell crank lever 61, one arm of which is forked and engages. the shaft 41 beneath the head 42 and the other arm carries a roller 62 adapted to be engaged by the lever 63 secured through shaft 64 tothe hand lever 56. At the upper end of shaft 60 is the finger 66 which is shown projecting through a slot in the carriage and arranged to engage the cam 50 on lever 48.
- When hand lever 56 is pulled up by' the oplever 63 engages roller 62 which erator,
the bell crank 61 and shaft 41 withthrough draws the half nut 40 from its shaft and through finger 66 depresses the adjacent end of lever 48 so as to lift the stylus from the record blank. Continued movement of the hand lever 56 causes the entire carriage with parts connected therewith to slide on its uides 36 and 37 to its initial position. Just fore it reaches its final position it engages the spring 67, compressing it a small amount while a squared portion of the bell crank 61 engages one or the other of the two books 68 and 69 which retains the carriage in the returned osition. The hand lever- 56 may then be released and by spring 70 is returned to its initial position. The two books 68 and 69 are identical in construction, being both 'voted on the stud 72 and being connected y similar links 73 and 74 through in and slot connections -with-the rocking p ate"7 5. This late is connected through shaft. 76, crank 7, rod 78 and eccentric 79 to shaft 32 so that when the turntable is again started 65 permit spring 67 to move it forwar the. two hooks 68 and 69 will be caused to oscillate in opposite direction, thus whichever hook retamed the carriage in its returned position will release the carriage and .ther liftedofi the recor until molten centric 79 rather than toan extreme pos1- tion thereof as illustrated. Upon the return movement of the carria e the stylus was fur-5 d blank by the engagement of the lever 48 on the cam 80 which is fixed in position and isso constructed that the stylus operating mechanism 49 is lifted sufiiciently high to enable the operator easily to remove the record without its touching the stylus.
Inasmuch adapted to receive a record on both sides and since it is desirable to make provision in the machine for permitting two operations of the machine but-preventing more than two, we
have shown the machine as having the mech lower end of the carriage 38 is mounted a spring-pressed pawl 82 which engages. the ratchet 83 to which is secured the cam 84 and one end of the strap 85 to which is attached the spring 86. Cam 84 is adapted to engage the contact spring 87 and separate it from contact spring 88, it being understood that a suitable stop, not shown, is provided for the cam 84 when it is returned by the spring 86. Springressed pawl 90 retains the ratchet and is a apted to be withdrawn from engagement therewith by the lever 91 operated by the electromagnet 92. The first return movement of the carriage after a record has been cut on one side of the blank rotates the ratchet wheel 83 one tooth causing cam 84 to ap roach but not touch the-spring contact 87. The second return movement of the carriage after the other side of the record blank has received its record rotates the as the record blanks which are furnished for use with this machine are ratchet another tooth and brings the cam 84 a into position to open the circuit between springs 87 and 88 which, as will be described later rendersthe mecha any further recordingb until the coin-operated device has again een operated.
For the control of the two signal lights 9 and 10, which are shown arranged in front of the operator and which preferably are green and red respectively, we have rovided the control switches 95 and 96. he former is closed in response to' the downward movement of the stylus actuatingmechanism nism inoperative for naeasu 49, being adjusted to operate when the carrlage in its forward movement-reaches the point at which the. lever 48 in riding down the cam 80 allows the stylus to come into contact with the record blank. Thus' the lighting of the green signal lamp 9 notifies the operator that it is time'to begin to talk. When the carriage in its forward movement approaches its limiting position, namely reaches a point at which the operatorhas but a few seconds more to talk before the turntable is automatically stopped, it rides on an inclined portion of the switch 96 and closes the circuit thereof thus illuminating the red signallamp 10.
During the recording process the shavings from the blank fall from the turntable into the rece tacle 97 which surrounds the turntable. onnected with this receptacle by the pipe 98 is the motor driven exhausting fan 99 and the collecting bag 100. The turntable preferably is provided withtwo wipers or brushes 101 which move the shavings to- Ward the opening of the suction pipe 98 and pulverize the same. The motor of this fan is connected to the switch 102 mounted on the door and arranged to be operated by the unlocking movement of the handle 4 mounted on shaft 103.
The switch 102 normally engages the fixed contact 104 which is included in the operating and holding circuit of the master relay 4 105 having armature 106. When switch 102 is operated, however, it breaks contact 104, thus releasing the master relay, and engages a second fixed contact 107 which closes the circuit of the motor of the exhausting fan 99.- The hand switch 8 by which the turntable is started and stopped at the will of the operator,
controls the motor relay 109 having armature 110 by which the motor circuit is controlled.
Mounted preferably beneath the apparatus cabinet 6 in the booth is the cabinet 112 contaming suitable thermionic amplifying devices connected with the microphone? and with the electromagnetic cutter 49. Through the leads 113 circuit connections for the motors, the signal lights, the relays, the magnets, etc. are made with a suitable source of operative current.
The operation of the above described apparatus is as follows: An operator desirous of recordlng a message would, according to printed instructions, first insert a suitable coin, for example a piece, in the slot 13 and then turn the handle 14.; The turning of the handle '14 operates to release one record blank from the bottom of the vending machine 12 within the booth and by the closing of the circuit at contacts 17 and 18 by cam 16 energizes the coil 23 to unlock the door, which it will be understood was previously closed and locked. The operation of the unlocking means closes the circuit between contacts 25 which shunts contacts 17, 18 to hold the door r unlocked after the handle -14 has been released. The turning of'the handle 14 also closes the circuit of the master relay 105 b the touchin of contacts 18 and 19, this circuit being comp eted through the switch 102'and contact 104. As soon as the master relay 105 operates its armature closes a shunt circuit about contacts 18 and 19 by which the relay is locked in closed position. Closing of the relay 105 also closes the circuit of the dome light g 11. The operator-then pulls open the door and enters the booth, the opening movement of the door serving to release the door unlocking circuit by the separation of contacts 27 1 and 28 whereby upon assuming closed position the door again becomes locked. The operator now takes the record blank which was released from the vending machine and I places it upon the turntable 34, it being noted that the carriage and the protective cover 57 has already been moved back clear of the turntable. The switch 8 is now grasped by the operator who stands or sits facing the i release the same and allow the carriage to be,
started on its forward movement by the spring 67. The half nut ,40 thereupon engages the screw 44. As the carriage is slowly advanced the stylus supporting lever 48 slideson the cam 80 until the stylus is al-' I lowed to come .into cutting engagement with the record blank. At this instant the switch 95 is closed which illuminates the green light 9 which is the signal to the operator that it is time to begin to talk. 'By releasing and closing the hand switch 8 the operator may stop and start the turntable as often as he pleases. When the carriage has progressed to a point which is within a few seconds of the limiting position, the carriagerides upon the inclined portion of switch 96.and in closing the circuit of that switch illuminates the red lamp 10, thus notifying the operator that he has but a few more seconds to talk. Upon reaching the limiting position the'carriage engages the rod 52which opens motor circuit at. contacts'53 and 54. In this position of the carriage the record cannot be removed.
The operator thereupon pulls up on the hand lever 56 which through lever 63, bell cank lever 61 and finger 66 first lifts the stylus from the record then withdraws the half nut 40 from the screw 44 and upon furthermovement pushes the entire carriage back until it again becomes engaged by one or the other or both of the two hooks 68, 69. Inthis return movement of the carriage the stylus supporting lever 48 rides up on the cam 80 so the hand lever .to its initial fers, he may continue his message on the reverse side of the blank. If he so desires he turns over the record, placing it on the turntable as before and again grasps the hand switch 8 and makes a second recordin in the same manner as he did the first. T e first time that the carriage was moved back by osition the ratchet 83 was rotated one toot namely to the position shown in Fig. 1. In this position cam 84 attached to the ratchet wheel approached but did not touch the contact spring 87. By the second turn movement of the carriage the ratchet wheel 83 is rotated another tooth which-is sufiicient to bring the cam 84 into operative engagement with the contact spring 87 so as to open at that point.
the control circuit of hand switch 8. The operator is powerless thereafter to start the motor until the ratchet and cam have been restored to their initial position. The ratchet is maintained in its rotated position by the spring pressed pawl 90 which pawl is adapted to beireleased by the energization of magnet 92. i
The operator now removes the blank from the turntable and by turning the door handle 4 unlatches the door and steps out of the booth. The act of turning the handle 4 to unlock the door operates through the shaft 103 and switch 102 to break the holding circuit of the master relay 105, allowing this relay to fall open. Operation of switch 102 also closes at 107 the circuit of the electromagnet 92 and the motor of the exhaust fan 99 so that'for the brief interval that the door handle 4 is operated the exhaust fan is in opera 'door sets the machine ready for the next operator. Since the circuit of the master relay 105 was opened by the first movement of the door handle 4 and switch 102 the entire mechanism now is inoperative until the master relay is again energized by the insertion of another coin in the coin-control'device and the turning of handle 14. Upon leaving the booth the door swings closed and locks whereupon the entire apparatus is again in condi tion for another complete operation in the manner above described.
