5 Claims.
This invention relates to phonographs, and
more particularly to phonographs of the type which comprise a speaking tube, or the like, for conveying sound to and from the machine.
Phonographs of the abovementioned type are commonly employed for the recordation and reproduction of dictation, and are known as dictating machines. These machines comprise means for rotating a record and a record-cooperating sound translating device usually at leas partially overlying the record. To this translating device there is coupled a speaking tube having a handpiece, or sound-receiving device, at its outer end adapted to be grasped by the hand during the use of the machine, the speaking tube being usually flexible and of such length as to permit freedom of movement to the operator during the use of the machine. For convenience in the operation of the machine, it is important that the point` at which this speaking tube extends from the machine be carefully chosen so that the tube will not obstruct such access tothe machine asis necessary to its operation; it is further important, particularly in machines which are intended for use on desks or tables, that the arj rangement of the phonograph and cabinet be highly compact and yet provide sufficient space for the storing of the speaking tube during the non-use of themachine.
It is an object` of my invention to provide an 4 arrangement of` phonograph and cabinet fulfilling the important requirements, as noted above.
It is another object to provide a cabinet closely fitting a complete phonograph, which is-openable by a single manipulationto expose .the phono- I speaking tube during, the non-use of the machine.
It is a further object of my invention to couple the sound translating device to the speaking tube by means of a sound tube partially surrounding the record rearwardly thereof.
It is another object of my invention to provide 5i a movable support in the abovementioned compartment for the handpiece ofthe speaking tube, which is automatically moved into an upper supporting position rendering the handpiece readily accessible upon opening the cabinet and into a lower supporting position upon closing the cabinet.
A further object of my invention is to provide improved means for automatically starting the machine as an incident of removing the handpiece from its support while the support is in its upper supporting position.
Other objects of my invention will more fully appear from the following description and the appended claims.
In the description of my invention reference is had to the accompanying drawings, of which:
Figure 1 is a top plan view of a phonograph and cabinet in accordance with my invention, the top of the cabinet being removed for the better illustration of the phonograph;
Fig. 2 is a vertical cross sectional view of the phonograph and cabinet in accordance with my invention, taken substantially along the line 2 2 of Fig. l, but showing the speaking tube in elevation;
Fig. 3 is a fragmentary vertical cross sectional view taken substantially along the line 3 3 of Fig. 1;
Fig. 4 is a right side elevational View oi the cabinet of the above figures, a side wall portion of the cabinet being broken away for the better illustration of parts therebehind;
Fig. 5 is a fragmentary sectional view taken substantially along the line 5 5 of Fig. 4;
Figr is principally a left hand elevational view of. mechanism operated by the cover or main closure, the cover being in open position;
Fig. 7 is a verticaly cross sectional view of the mechf-niism` shown in Fig. 6,` taken substantially along the line 1 1 of Fig. 1; and
Fig. 8 is a detailed View of a portion of the mechanism of Fig. 6, taken substantially along the line .8 8 of Fig. 6.
Reference being had to Figs. 1 and 2, there will be seen a cabinet i having a lower portion Z which is substantially rectangular in cross section as viewed from the top, and a top portion, which is substantially arcuately shaped as viewed from the end, the top portion comprising a rearward section 3 and a front closure or cover il. The cabinet l contains a phonographarranged in accordance with my invention, having a frame or base G carrying the various parts of the phonograph. The lower cabinet portion 2 supports the base 6 in a position at the level of the top of that portion, the base being supported at its front by a bracket l, which is secured to the forward wall of the lower cabinet portion 2, and at its rear by left and right brackets 8 and 9 secured to the rearward wall of the cabinet portion 2 and respectively pivotally connected by shoulder screws 8 and 9 to left and right rearwardly extending arms l) and l I provided on the base.
The phonograph has its principal parts disposed at, or above, the general level oi the base 5 in order to form a compartment i2 beneath the base in the lower cabinet portieri 2. The phonograph parts which are disposed above the base 6 are carried principally by an intermediate upright standard I3 and by left and right upright standards I 4 and I5 of the base 6. In the intermediate standard I3 there is journalled a shaft I6 having a mandrel Il' to the right of the standard for removably carrying a cylindrical record I3. The portion of the base 6 which lies along the record Iiii. e., the portion lying to the right of the intermediate standard I3-comprises a raised portion in the form of a platform I9 disposed behind the record and curving downwardly about the record to form an arcuate portion 23. Extending forwardly from the arcuate portion 2i] is a fiat downwardly inclined base portion 2I having a relatively large laterally extending opening 22 exposing the interior of the compartment I2, The portion 2| terminates along its forward edge in a vertically extending reenforcing rib 23 which normally rests on the bracket l. The rib 23 is integral with left and right vertically disposed side ribs 24 and 25 (see Figures 6 and '7) which extend from front to back along the side edges of the base 6 and terminate in the left and right arms Ii) and II. The left side rib 24 has a downwardly curved central portion 24' which is offset to the right to provide space to the left thereof for mechanism hereinafter described, the portion 24 also serving as a support for parts of the phonograph.
Supported by the left and right standards I4 and I are the fro-nt and back longitudinal rods `arid 3|. Slidably mounted on these rods is a carriage 32 having a sleeve 33 embracing the rod 3). The carriage 32 is provided with a forwardly extending arm 32 overlying the record I8 and carrying a sound translating device 33 adapted to cooperate with the record. Advancing movement of the translating device 33 from a start position to other positions across the record I3, coincidental with a rotation of the mandrel I1, is effected by a driving means comprising a feed screw 34 rotatably supported by the left and right standards I4 and I5 and geared to the mandrel shaft I5 by a train of gears 35, of which the intermediate gear 35 is pivoted on-a` rearward extension I3' of the intermediate standard I3. Movable into and out of engagement with the feed screw 34 is a feed nut 36 secured to a bracket 31 pivoted to the carriage by a pivot rod 38. When the feed nut 36 and feed screw 34 are engaged a steady rotation of the feed screw will cause the translating device 33 to be steadily advanced relative to the record, but when the feed nut and feed screws are disengaged either the carriage arm 32 or the translating device carried thereon may be grasped by the hand and be manipulated across the record at wil1 such manipulation being particularly relied upon for the return of the translating device to start position.
The driving means for the mandrel and carriage may comprise a suitable electrical motor 33 preferably located in the rearward part of the cabinet I between the left and right `arms II] and I I of the base 5. The motor 33 has a drive pulley 40 coupled by a belt 46 to a pulley 4I rotatably mounted on the standard I4 with its axis in line with the mandrel shaft I5. The pulley 4I is coupled at will with the mandrel shaft I6 by means of a clutch 42 comprising a toothed circular member 43 suitably splined to the mandrel shaft It and movable into and out of engagement with another toothed circular member 44 provided on the pulley 4I. For moving the member 43 leftwardly and rightwardly on the mandrel shaft I6 to effect the engagement and dsengager ment of the clutch 42 there may be provided a movable control member 45 carrying a pin 46 engaging an annular groove 4l in the clutch member 43.
In order that a belt may freely pass from the drive pulley 43 to the `driven pulley V4I there is provided between the left standard i4 and the intermediate standard I3 a rearwardly extending channel 43. The bottom 43 of the channel is on a level with the lowest part of the arcuate portion 2) of the base; the left side of the channel is formed by the standard I4; and the right side of the channel is formed n part by the intermediate standard I3, in part by the rearward extension I3 of this standard, and otherwise by a wall 5D which extends rearwardly ofthe extension I3' between the platform I9 and the bottom 49 of the channel.
The sound translating device 33 may have an inoperative condition and respective operation conditions for recording and reproducing. When conditioned for recording, the translating device is adapted to receive sound waves and impart a movement undulating in accordance with those waves to a recorder stylus 5I which, when in contact with a rotating record, forms a progressive modulated groove thereon, and, when conditioned for reproducing, to create sound waves in accordance with any undulating movement imparted to a reproducer stylus 52, as by the engagement of the reproducer stylus with a progressive modulated groove on the record E8.
The translating device may be shipped between inoperative and operative conditions at will and may be manipulated across the record when the feed nut 35 is disengaged from the feed screw 34 as is hereinbefore described. The means for shifting the translating device between inoperative and operative conditions, and for controlling the engagement of the feed nut 36 with the feed screw 34, comprises a forwardly extending control or shifting lever 53 which is pivoted by a pivot screw 54 on a boss 54 provided on the right side of the carriage arm 32. The control lever 53 has a short downwardly extending arm 55 pivoted by a pin 55 to a link 56 which in turn is pivoted by a pin 56' to a block-shaped member 51 pivotally mounted on the sleeve 33 within the hub portion 32 of the carriage 32. Upward and downward rocking movement of the lever 53 from its intermediate position shown in Fig. 2 thus causes clockwise and counterclockwise angular movements of the member 5l. The condition of the translating device and the position of the feed nut 36 relative to the feed screw 34 are controlled in accordance with the angular positioning of the member 51 by a mechanism not herein necessary to show. When the control lever 53 is in its intermediate position the feed nut 36 is out of engagement with the feed screw 34 and the translating device is in an inoperative condition, the recorder and reproducer styli 5I and 52 each being then in a raised position free of the record I8 when the control lever 53 is moved upwardly from its intermediate position the feed nut 36 is brought into engagement with the feed screw 34 and the translating device 33 is placed in a condition for reproducing, the reproducer stylus 52 then being in engagement with the record I8; and when the control lever 53 is moved downwardly from its intermediate position the feed nut 36 is again brought into engagement with the feed screw 34 but the translating device is placed in a condition for recording, the recorder stylus I then being in engagement withy the record I8.
To facilitate the mounting of; a record4 on, and its removal from, the mandrel I1 there is providedv a record ejector, preferably ofthe type disclosed' in Gramann PatentNo. 2,010,717, issued on. August. 6, 1935, and entitled Phonograph. This record ejector may be sufficiently described in the present instance by ther following statements:A The ejector.` comprisesv aV disc-shaped member biased rightwardly` and arranged to abut against the leftV end of. the, record. At `the free end of `themandrel there isprovidedanexpansible and contractible chuck 21'I'biased into an expanded position but adapted to be heldiin a contracted positiony and to be released therefrom by a leftward movement `of the disk member 26. When a record is mounted on the mandrel the disk member 26 is moved leftwardly to release the chuck 2T and the chuck 2.1' then expandsto hold the record on the mandrel. To eject` the recordthechuck 21l is contractedby imparting an inward movement to a ,manually operable-control 28 carried by the mandrel at` the` free end thereof. When` the chuckA is contracted, the record is ejected by the rightly: biased` disk member 26, the chuck then being again releasably held in a contracted position.
Whenever a reccrdis to be mounted on or removed fromv the mandrel I1 thevfree end ofthe mandrelfmust be fully exposed. For this reason the pivoting of the cover` 4 at its right side must be effected by a pivoting means` which will: not obstruct the free end ofthe mandrel; Suchpivoting may be effected by anarcuate member- 58 (see Fig. 4) provided with au longitudinally extending channel' 59' facing tothe vright and having a longitudinal slot extending substantially throughout the lengthyy thereof. The arcuate member 58 is slidablyv supported by and effectively pivotedto: the rightl standard' I5 bymeans of thel upper and lower headed screws and 661which pass through the slot Btl, thread into the standard, the respective heads 65 and 66'V of' these screws being disposed Within the channel59. Extending throughoutthe length ofthe arcuate member are inner and outerl strips 6I andy 62;A along the forward' portion of the member 58 the strips 6I' and 62 are each secured, as by welding, to the right end wa1l63`of the cover 4; but at an intermediate point 64 along the member 5B' (see Fig. 5) the strips BI and62f are each offset to theleft away from the end. wall 53 to provide a clearance, as is hereinafter described;
The left side of the cover 4.is pivoted to the left standard I4?, as shownin- Fig, 1" and' 6, by means of anarm 65 whichisfsecured asfbyweldinglto a left'. end wall166 ofthe cover andvpivoted to a` leftwardlyextending bossSfI on thestandard I4 by a pivot screw 68. The inneredge 66! of the end wall |56l is curved in anarc about' the pivot' screw 68. The centralportion ofi the lefthand endwall of the cabinet is not'closedby-the cover 4 and the rearward sectionV 3.; For thisfportion there may be provideda closure 69f1bent inwardly to form a guard or frontx closure '69"for the pulley 4i and clutch 42, the front closure 69." being shaped to conform with theedgeIB' of' the leftend wall 55 ofthe cover 4.
The open and" closed positions of the cover 4: are respectively shown in Figs. 6r and 2. The opening `of'the cover 4 isadapted'fto-provide such access to" the front portion of the phonograph as is necessary to. its` operation. The movement of the cover 4- from closed.. to open position. is.
however, insufficient in itselfy to fully expose the free, end of the mandrel II. For this reason, the freer end of the mandrel I'I is closed partially by the righthand end Wall 63 of the cover 4 when the cover` is in closed position and otherwise by a separate side closure-'I0 for the cabinet, as is disclosed in myPatent No. 2,203,096 issued June 4, 1940. Theclosure 'Ill is provided with a supporting arm 1I. lying adjacent to the` inner surface of the wall 6,3 and pivotedthereto by a pivot screw 12; it is for the purpose of clearing the arm 1I that the arcuate member-58 is offset at 6,4, as is aforementioned. This supporting` arm is offset to the right along the line'IBtO-permit the closure 'Ill to be in substantial alignment with the end Wall 63- of the cover, the upper edge 'I0' of the closure 'I0 being shaped to conform with the inner edge 63 of the end wall'63. To reenforce the conneetionof the closure Ill to the, cover 4, the arm 'II is provided with a slot 14, curved in an arc about thefpvot screw 12, through which slidably passes a headed pin- 'I5 secured, as by riveting, tothe end Wall` 63. Thus the sideclosure 10 is carried by, and movable relativelyto, the cover 4.
A movement of the side closure I0 relative to they cover, such as is necessary to eiect the open and closed positions of the` side closure, is adapted to occur as an incident of opening and closing the cover 4. Reference being had to Fig. 4 it will be seen thatv when the cover 4 is closed the side closure 'IILis urged by gravityinto its closed position. As the-cover 4 is opened the side closure 10, is urged bygravity in at counterclockwise direction relative tothe cover, into its open position, shownin dash-dot lines in Fig. 4 and defined by the contact of the pin 'I5 in'` the forward end of the slot 14. In order, however, to insure the positive opening and closing of the side closure 'I0 coincidentally with thev opening and closing of the cover 4, the supporting arm 1IY is provided with an upward extension I6 andon the standard I5 there are provided the brackets TI andl 18, secured to the standard by the screws 'I'I and 18', which respectively lie in the terminal positions of the path of the extension 15. As the cover 4 nears-its` openposition, the extension 'I6 impinges upon the bracket 'I1 to cause the side closure 1D to` be` positively moved into open position; and when the coverl! nears" its closed position the extensionv 16- impinges uponthe bracket '18. to cause the-sideY closureto be positively moved into closed position.
In the operation of the machine, sound is conveyed to the translating device 33 during recordlng and from the translating device during reproducing. For conveying the sound to and/or from the translating device there is provided a flexiblev sound-conveying tube 78, commonly known as a speaking tube, having a handpiece or sound-receiving device =8D atits outer end usable as a mouthpiece duringrecording and as an earpiece during reproducing. The handpiece usuallycarries a suitable control means for the phonograph, not herein necessary to show. operable by moving aplate or cover 8I inwardly as by agraspof thehand, this control meansbeiner connectedwith the phonograph by a cable 82 which may pass within and along the tube and extend therefrom as through a vent 83.
The speaking tube 'I9 has a considerable size. having a substantial diameter to permit eiciency in sound conveyance and a substantial length. to permit freedom of. movement to the operator during the use ofthe machine. Because of this l, size of the speaking. tube therek is encountered,
particularly in compactly arranged -machines adapted for use on desks r the like, a dicult problem in finding sufcient space for the storing of the tube during the non-use of the machine. Furthermore, if the speaking tube is directly connected to the translating device it may obstruct such access to the translating device 39 or carriage 32 as is necessary for manipulation to move the translating device across the record, or it may obstruct access to manipulative means in the vicinity of the translating device such, for example, as the control lever 53 heretofore described, or a marking guide 84 carried by the carriage arm 32 (see Fig. 2) along which a pencil may be manipulated to mark an index slip S to indicate positions of the carriage in its travel along the record, (the index slip S being for example held in an index slip holder 85 secured to the forward portion 2 of the base 6 by the screws 96) In accordance with my invention, I provide the compartment I2 beneath the phonograph for the storing of the speaking tube 19 and handpiece 80, which compartment is relatively flat so as not to substantially increase the overall height of the machine; I further couple the speaking tube 19 to the translating device 33 by means of a sound tube 81 extending rearwardly-from the translating device and downwardly behind the record I3 into the compartment I2. When the machine is used, the handpiece 816 is taken out of the compartment by way of the opening 22; the speaking tube then extends outwardly from a lower portion of the machine leaving the upper portion ofthe machine, wherein the abovemens tioned manipulative means are located, freely accessible. Moreover, since in this arrangement the speaking tube does not obstruct the translating device forwardly thereof, the cover y4v may be placed immediately adjacent to the translating device so as to render it readily accessible when the cover is open.
The sound tub-e 81 is secured to the translating device 33 by means of an annular coupling 88 and is disposed rearwardly of the translating device, the tube passing over and behind the longi-v tudinal rod and terminating at a point behind the record I9. On the left side of the carriage 32 behind the record I8 there is provided a boss 39 having an opening 90, which boss is preferably integrally formed with the carriage as by casting.
The upper end of the opening 90 is provided with a resilient bushing 9|, preferably of rubber, into which the sound tube 81 tightly lits. Fitted into the lower end of the opening 90 and extending downwardly therefrom through a laterally extending opening 92 in the platform I9 of the base 5, is a coupling member `93. The coupling member is secured to the boss 89 as by a pin 89'; it is provided with an enlarged diameter end portion 93 which fits about the inner end of the speaking tube 19, and which is secured to the speaking tube by a set screw 94.
`When the handpiece 80 is 'inserted in the cornpartment I2 the speaking tube 19 coils itself about in the compartment |'2 in a manner such as is shown in Fig. 2. Since the cover 4 is tted closely to the opening 22 of the compartment I 2 the handpiece 80 must lie substantially within the compartment I2 whenever the cover is closed. lIn the compartment I2 there is provided a support95 for the handpiece 80 having a widened and arcuately shaped end portion 95 tting the handpiece, as is shown in Figs. 1 and 2. The support 95 is movable between upper and lower positions and comprises right and left upwardly extending arms 96 and 91 interconnected by a bail 98. The arm 9B passes through an opening 99 in the bottom 49 of the channel 48 and is pivoted by a pivot screw |99 to the left side of the intermediate standard I3 between this standard and the intere mediate gear the gear being spaced clear of the arm 95 by means of a boss I3" on the left side of the extension I3', as is shown in Fig. 7. The leftarm 91 lies to the left of the central portion 24 of the reenforcing rib 24 and is V-shaped, as is shown in Fig. 6; it is pivoted to the boss 61 of the stan-dard I 4, to the right of the aforementioned arm 65, by the pivot screw B8.
In order that an opening of the cover 4 will l eifect a movement, through the opening 22, of
the support 95 from its lower supporting position within the compartment I2 to an upper supporting position, shown in Fig. 6, to render the handpiece 80 readily accessible, there is provided an arm |0| on the arm 05, which extends downwardly to the left of the arm 91. The arm IUI is coupled to the support 95 by means of a pin |02, carried bythe arm I9I, which engages a slot |03 that is provided in the arm 91 and curved in an arc about the pivot screw 68. By reason of this coupling the support 95 is swung in the same direction as the cover 4 with the opening and closing of the latter. The angular distance between the open and closed positions of the cover 4 is, however, greater than the angular distance between the upper and lower supporting positions of the support 95, respectively shown in full and in dash-dot lines in Fig. 6. The slot |03 however provides a lost motion between the cover 4 and support 95, which is equivalent to the diiference in theirangular travel.
When the support 95 reaches its upper supporting position' it is restrained from moving downwardly therefrom, except as an incident of closing the cover 4, by means of a latch |04 pivoted by a pivot screw |05 on a boss |06 provided on theleft side of the reenforcing rib 24'. In the opening of the cover 4 the bail 98 contacts an inclined face |01 on the latch |04 and slides thereover. When the bail has passed the face |01 the latch snaps upwardly against a stop pin |08, by reason of a tension spring |09 connected between a short arm |04 of the latch and a pin I I0 on the rib 24, to restrict the support against downward movement. As the cover is closed the pin |02 iirst traverses the slot |03, but before this traversal is completed a cam face III on the arm IOI contactsa pin I|2 on the latch |04 to cause the latch to be moved free of the bail 98, the support 95 then being free to move downwardly within the compartment I2.
In order that the motor 39 may start automatically as an incident of removing the handpiece from the support while the support is in its upper supporting position, there is provided means for `eifecting an upward movement of the support, into an upward position shown in dashdot lines in Fig. 6 and hereinafter called its nonsupporting position, incidental to the removal of the handpiece 80 therefrom, and this movement of the support is adapted'to place the motor 39 in operation. This means comprises a cantilever spring |I3 secured to the arm 91 by pins H2. When the cover 4 is opened the front edge |0| of the arm |0| is brought to bear against the spring I I3 and'to impart an upward biasing to the support such as will move the support into non-supporting position when the handpiece 80 is removed therefrom. The weight of the handpiece 89 is, however, suicient to overcome the upward biasing of the support 95 so that the support will always move downwardly into the upper one of its supporting positions as thehandpiece 80 is placed thereon.
On the left side of the central portion 24 of the reenforcing rib 24 there is secured by the screws ||4 a normally open control switch ||5. This switch comprises a frame IIB-of suitable insulating material, preferably of Bakelite, on which there are mounted front and back switch contact springs H1 and IIB. These contact springs may be appropriately connected, as by a cable I|9 leading from the frame ||6 by way of the vent |20, into a power supply circuit (not shown) of the machine so that closing and opening of the switch will respectively cause the starting and stopping of the motor 39. Secured, as by riveting, to the back switch spring ||8 is a downwardly extending arm |2|. This arm lies immediately ahead of a cross pin |22 carried by the arm 91 of the support 95. When the support 95 moves upwardly into its non-supporting position the pin |22 contacts the arm |2| and moves the switch spring ||8 forwardly to cause the closing of the control switch ||5, and when the support 95 moves downwardly out of its nonsupporting position the switch spring ||8 is rendered free to move. rearwardly, as by its own bias, to cause the opening of the control switch I5.
Thus, the removal of the handpiece 80 from the support 95 is adapted to start the machine operation; whereas the mounting of the handpiece 80 on its support is adapted to stop the machine operation.
