18 Claims. rcr. 274 1v) This invention relates to phonographs, and more particularly to phonographs of the commercial type. An important aspect of the present invention is in the provision of a cabinet for a commercial phonograph wherein there are provided operative connections between the phonographs and the cabinet. In some respects the present invention relates to improvements over the copending application of Louis Z. La Forest, Serial No. 180,940, filed December 21, 1937, and entitled Phonographs (which application is now issued as Patent No. 2,203,096).

When commercial phonographs, or dictating machines, are made small and completely enclosed by cabinets closely fitting the phonograph for the purpose of rendering the phonograph readily portable and suitable for desk use, the ease of operation of the phonograph may be impaired unless the phonograph and cabinet are carefully designed and well adapted to each other.

One of the diificulties encountered with a cabinet of the abovementioned type lies in rendering the phonograph accessible for convenient operation with the use of a small closure which will closely fit the cabinet while the closure is in open position. As described in the abovementioned copending application, this difiiculty has been circumvented by the provision of a plurality of closures. cover and a pivotally mounted side closure which are separate of each other but which are interconnected for simultaneous opening and closing thereof. Theimproved means herein disclosed for interconnecting these closures is now described and claimed in my copending divisional application Serial No. 386,225 filed April 1, 1941.

A difficulty encountered when the phonograph and cabinet are made small, is in arranging the machine and cabinet so that the phonograph control means is readily accessible and of such size as to be easy to operate. An object of this invention is to overcome this difficulty by placing the control means into such spaced relationship with the cabinet that the range of movement thereof extends from within the cabinet to a position or positions beyond the cabinet.

With such arrangement of the control means there is, however, encountered the possibility of the operator moving the control means into a position outwardly of the cabinet, as during the use of the phonograph, and then inadvertently attempting to close the cabinet without first moving the control means into a position within the cabinet.

These closures may comprise a main It is an object of this invention to avoid such difiiculties by interconnecting the control means with a closure of the cabinet so that the control means is automatically moved into the cabinet as an incident of closing the same.

Another object is to provide a plurality of simultaneously controlled closures for a phonograph cabinet, Which are coupled to a phonograph control means projecting beyond the cabinet so as to move the control means into a position within the contour of the cabinet as the cabinet is closed.

Other objects are to move a control means for the phonograph from an operative position beyond the cabinet into a neutral or inoperative position within the contour of the cabinet as the cabinet is closed, and to lock the control means against movement into a position beyond the cabinet while the cabinet is other than fully open.

It is a still further object of my invention to prevent possible extraneous movements of parts of the phonograph-the carriage, for exampleas by a tilting of the phonograph during its transportation. A feature of my invention is to obstruct or lock the carriage against such movement when the cabinet is closed.

Still other objects and features will appear from the following description and the appended claims.

In the description of my invention reference is had to the accompanying drawings, of which:

Reference being had to the figures, particularly Figs. 1 and 2, there will be seen a cabinet I closely fitting a phonograph of the type commonly used for the recordation and reproduction of dictation. The lower portion 2 of the cabinet, comprising substantially the lower half thereof, is rectangularly shaped and preferably formed, as by casting, in an integral piece. by the lower portion 2 is a base plate 3 hinged to the rearward wall 4 of the portion 2 and resting on a stud 5 provided on the forward wall 6 of the portion 2. The plate 3 has left and right upright standards of which the right standard appears as I; these standards carry the front and back longitudinal rods 8 and 9 on which there is slidablymounted a carriage Ill. The carriage I!) has an arm II extending forwardly above a cylindrical record I2 which is removably carried by a mandrel I3. Movement of the carriage I0, longitudinally of the record I2, may be effected by a driving means comprising a feed screw I4 (see Figs. 3 and 4), which is rotatably supported by the abovementioned standards and with which there is brought into engagement a feed nut I5 secured to a bracket I6 pivoted to the carriage by a pivot rod I1. When the feed nut I 5 is in engagement with the feed screw I4, steady rotation of the feed screw will cause the carriage Ill to be steadily moved across the record I2. Such rotation of the feed screw I4, as well as rotation of the mandrel I3, may be effected by a suitable driving motor not herein necessary to be shown. When the feed nut I5 is, however, out of engagement with the feed screw I4, the carriage is freely movable at will along the record I 2.

The carriage arm II carries a translating device I 8 shiftable from an inoperative condition into respective operative conditions for recording and reproducing. When conditioned for recording, the translating device is adapted to receive sound waves by way of a tubular element I9 on the translating device, and impart a movement undulating in accordance with those waves to a recorder stylus 20, and, when conditioned for reproducing, to create sound waves in accordance with any undulating movement imparted to a reproducer stylus 2|, as by the engagement of the reproducer stylus with a progressive modulated groove on the record I2.

The means for controlling the engagement of the feed nut I5 with the feed screw I4, and for shifting the translating device between inoperative and operative conditions may comprise a forwardly extending control or shifting lever 22 which is pivoted by a pivot screw 23 on a boss 23 provided on the right side of the carriage arm I I. The control lever 22 has a relatively short downwardly extending arm 22 which is connected, as by a link 24, to a block 25 provided within a hub portion I0 of the carriage I0 and embracing the rod 8, the link 24 being pivoted to the arm 22' by a pin 26 and to the block 25 by a stud 27 extending rightwardly of the block through an opening 28 at the right side of the carriage. Thus, as the control lever 22 is rocked upwardly Supported I and downwardly from its inoperative position shown in Fig. 4, the block 25 is rocked in clockwise and counterclockwise directions about the rod 8. The block 25 is coupled to the translating device I8 as by a coupling means not herein necessary to be fully described. This coupling means is arranged so that movement of the control lever 22 from an inoperative position into the upward and downward positions shown in Fig. 2 (the downward position being shown in dash-dot lines) causes the translating device to be respectively conditioned for reproducing and recording, the conditioning of the translating device being effected as by a camming action between a cross pin 29 carried by the block 25 and the lifting arms 39 (fractionally shown in Figure 4) In moving the control lever into either of its operative positions, that is the upward or reproducing position and downward or recording position, the feed nut I5 is brought into engagement with the feed screw it, as by a camming action between the pin 29 and an arm 3I on the bracket I 6. Thus, when the control lever 22 is in an upward or reproducing position, the feed nut I5 is in engagement with the feed screw I4 and the translating device is conditioned for reproducing, the reproduoer stylus 2| then being in engagement with the record I2; when the control lever is in a downward or recording position, the feed nut is again engaged with the feed screw but the translating device is conditioned for recording, the recorder stylus 20 then being in engagement with the record I2; but when the control lever 22 is in neutral or inoperative position, shown in Fig. 4, the feed nut is disengaged from the feed screw to render the carriage freely movable, at will, and the translating device is in an inoperative condition, both styli 2i] and 2I then being out of engagement with the record I2.

In a preferred form of cabinet the upper portion is substantially arcuately shaped in cross section, as viewed from the end, and comprises a detachable rearward closure section 32, a forward closure or cover 33, and a movable side wall section or side closure 34. By having the upper portion of the cabinet arcuately shaped, sufiicient accessibility may be provided to the front portion of the phonograph by the opening of the cover 33, which need not swing outwardly of the cabinet for opening movement but which may be pivotally mounted to swing upwardly within the rearward section 32. In such upward position, the cover 33 may conform closely to the walls of the rearward section 32 and thereby utilize very little of the interior space of the cabinet. The side closure 34 may be moved into an open position to provide access to the mandrel I3; in such open position the side closure 34 may conform closely to the walls of the cabinet and thereby also utilize very little of the interior space of the cabinet.

Since no access need be provided to the left side of the phonograph the cover 33 may be pivoted leftwardly thereof in any suitable manner not necessary to be herein shown. On the right side of the phonograph, however, there must be provided full access to the mandrel i3, and a form of pivotal mounting for the cover 33 must be used which will not interfere with such access to the mandrel. The cover 33 is therefore effectively pivoted by means of a sliding connection with the standard I of the phonograph. This sliding connection comprises an arcuately shaped member 35, formed as by stamping, made substantially equal to a half circle in length, and

provided with a-channelled portion 36 extending throughout the length thereof. In the channelled portion 36, longitudinally thereof, there is provided a slot 31. Passing through the slot 31 and threading into the standard I are the shoulder screws 38, the heads 38' of which are disposed for sliding movement within the channelled portion 36. Thus, the arcuate member 35 is supported by, and effectively pivoted to, the standard 1.

The forward portion of the arcuate member 35 is secured to the cover 33 by means of a small lug 39 turned up from the member 35, and by means of a narrow strip 40 bent over from the inner wall 36' of the channelled portion 36, the lug and strip being each secured to the righthand end wall 4| of the cover 33 such as by spotwelding indicated at 39. The rearward portion of the strip is offset to the left along the line 42 and is provided with a cam 55 for reasons hereinafter explained. With the above-described means, the cover 33 is effectively pivoted to the standard 1 without obstructing the free end of the mandrel l3.

The side closure 34 is supported by front and back arm extensions 43 and 44. In order that this side closure may be in substantial alignment with the end wall 4| of the cover 33, to form in effect an extension of the wall 4| when the cover and side closure are in their respective closed pin 45 to a downwardly extending arm 46 on the base plate 3. The back arm extension 44 is con-. nected to the end wall 4| of the cover 33, inwardly thereof, by means of a headed pin 41 secured to the arm extension 44 and passing through an elongated slot 48 provided in the end wall 4| of the cover, the slot 48 being substantially radially disposed in relation to the pivot axis of the cover. Thus as the cover 33 is swung upwardly into open position and downwardly into closed position, the pin 41 slides inwardly and outwardly along the slot 48 to swing the side closure 34 downwardly and upwardly, about the pin 45, into its respective open and closed positions. Since the back arm extension 44 is connected to the cover 33 inwardly thereof, the strip 40 of the arcuate member 35 is suitably offset along the line 42, as hereinbefore explained, so that the arm extension 44 may be clear of the arcuate member 35.

Whenever a cabinet is closely fitted to a phonograph it may be found diflicult to provide suiiicient space for the free and easy operation of manually operable phonograph control means. In the phonograph hereinabove described, it has been found important that the control lever 22 be extended forwardly of the carriage arm so that the control lever may be easy to operate, as by reason of the increased leverage obtained, and so that the operator may readily grasp the control lever without directing his attention thereto and without probability of striking his fingers against the record |2. When the control lever 22 is so lengthened, however, it is found that the control lever extends into the path of the cover 33 when the control lever is in its upward or reproducing position. Closing of the cover may thus be obstructed by the control lever. It is obviously undesirable to increase the overall size of the cabinet for the mere reason of providing sufiicient space therein for a range of movement of the control lever that is free of the path of the cover. In accordance with the present invention such need for enlarging the cabinet is overcome by the provision of simple means whereby the control lever 22 is moved into a position within the cabinet as an incident of closing the cover 33. 7

It will be understood that the embodiment of my invention illustrated in Figs. 1 to 7 inclusive contemplates not only the movement of a manually operable control means to a position within the contour of the cabinet but also the movement of the control means into its neutral or inoperative position, to place the machine itself in an inoperative condition, as an incident of closing the cabinet. More specifically, this embodiment of my invention is concerned with the type of control means which is active throughout a range of movement extending from within, or from the contour of, the cabinet to positions outwardly of the cabinet, and it contemplates a one-way automatic movement of this control means, or more specifically, a movement of the control means into a position within the contour of the cabinet as a closure of the cabinet is moved to closed position, but no movement of the control means as the closure is opened.

In order to effect, as an incident of closing the cover 33, a movement of the control lever 22 out of its reproducing position (wherein the control lever extends into the path of the cover 33) into its inoperative position (wherein the control lever is within the contour of the cabinet and out of the path of the cover), the rod 8 is mounted for turning movement thereof and the block 25 is splined to the rod 8 by means of a screw 49 threading into the block and slidably engaging a longitudinal slot 58 provided in the rod 8. The rod 8 is extended slightly to the right of the standard 1 and is there provided with an arm 5| which is secured to the rod 8 by means of a shoulder screw 52. Thus as the control lever 22 is moved upwardly and downwardly the arm 5| is rocked in clockwise and counterclockwise directions. Provided on the arm 5| is a rightwardly extending pin 53 which is arranged to engage with a cam surface 54 provided on the forward end ofthe inside wall 36' of the arcuate member 35. (The arm 5| may also, if desired, be provided witha downward extension 5| which is moved into a position to obstruct the mounting and removal of a record with respect to the mandrel 3, as the control lever 22 is moved into reproducing position.)

When the cover 33 is in open position, as shown in Fig. 2, the cam portion 54 is disposed rearwardly of the pin 53 and out of the range of movement of the pin. The control lever 22 may then be moved freely throughout its range of movement. Should the cover 33 be closed while the control lever 22 is in reproducing position, the initial closing movement of the cover will cause the cam portion 54 to impinge upon the pin 53 so as to move the arm 5| downwardly, thereby moving the control lever 22 out of the path of the cover into its inoperative position. Thus the control lever 22 is moved within the contour of the cabinet and the translating device i8 is rendered inoperative, as an incident of closing the cover 33. When the cover 33 is in other than a fully open position, any accidental attempt to move the control lever 22 upwardly, as into a position wherein the control lever 22 will interfere with the opening or closing of the cover, is prevented by the impingement of the pin 53 against the wall 36' of, the arcuate member 35. It will, however, be seen that the coupling between the control lever 22 and the cover 33 has a one-way action since'the control lever 22 is not moved by the opening of the cover.

The machine of the type here described is compactly arranged to render it readily portable. If, however, in its transportation it should be tilted while the feed nut I5 is out of engagement with the feed screw M, as when the control lever 22 is in inoperative position, the carriage may be moved back and forth on the rods 8 and 9 by its own weight. This possible extraneous movement of the carriage by its own weight is highly objectionable in that it may cause clashing of parts and possible damage to the phonograph. It is, however, a feature of my invention to avoid this possible damage to the phonograph by the provision of suitably controlled means for applying a braking action to the carriage so as to obstruct or look the carriage against extraneous movements thereof. To effect this braking action I couple the carriage to a member which extends along the path of the carriage and which is stationary longitudinally of such path. It will, however, be understood that in accordance with my invention this member need not be necessarily stationary in the direction of movement of the carriage at all times so long as the member is stationary in the direction of movement of the carriage when the phonograph is out of operation. Since the phonograph cabinet is normally closed during its transportation, the means for obstructing or locking the carriage may be readily controlled by the cover of the cabinet.

In the embodiment of my invention illustrated in Figs. 1 to 7 inclusive, the carriageobstructing means is of a friction type, this obstructing means being rendered operative when the cover 33 is closed and inoperative when the cover is open. This means for obstructing movement of the carriage by friction comprises a ridge 56 provided on the rod 9 throughout the length thereof. The rod 9 is pivotally mounted on the left and right standards of the phonograph and, as hereinbefore described, the carriage I0 is slidably mounted on the rod 9, the carriage being provided with a slot 51 which is engaged by the rod. When the rod 9 is turned, as in a counterclockwise direction, the ridge 56 is caused to bear against the wall of the slot 51 so as to impede any movement of the carriage. The means for so turning the rod 9 comprises an arm 58 pivoted on the right end of the rod 9 adjacent to the inner wall of the standard 1. The arm 58 is resiliently connected to the rod 9 by a torsional spring 59 which is coiled about the rod 9 and hooked at its respective ends on a pin 60 carried by the arm 58 and on a short arm 6| carried by a collar 62 secured to the rod 9 by a screw 63 (see Figure 6). The spring 59 urges the rod 9 in a counter-clockwise direction with respect to the arm 58 but such relative movement of the rod 9 to the arm 58 is limited by the impingement of the arm 6| with a pin 64 provided on the hub 58 of the arm 58. When, however, the arm 58 is moved in a counter-clockwise direction the rod 9 is yieldably moved therewith so as to cause the ridge 56 to bear against the wall of the slot 51, thereby impeding by friction any movement of the carriage.

The rod 9 is so moved upon a closing of the cover 33 by the engagement of a rightwardly extending pin 65,. provided on the arm 58 and passing through an opening 66 in the standard I, with a cam 55 comprising a turned-over piece on the strip 40 of the arcuate member 35. However, as the cover 33 is opened the cam 55 first rides off of the pin and then the arm 58 is moved in a clockwise direction by the engagement of a cam 6! with the pin 65, the cam 61 being provided on a bracket 68 which is spot- Welded to the right end wall 4| of the cover 33. As the arm 58 is so moved, the pin 64 impinges against the arm 6| to cause the rod 9 to be moved in a clockwise direction, thereby fully clearing the ridge 56 from the walls of the slot 51.

Thus in accordance with the first embodiment of my invention, as the cover 33 is closed the control lever 22 is moved into its inoperative position wherein it is within the cabinet, as hereinbefore described, and a braking action is applied to the carriage H! to obstruct a movement of the carriage such as, for example, may be caused by a tilting of the machine; and as the cover is opened no movement is imparted to the control lever 22, but the braking action on the carriage is relieved.

In the second embodiment of my invention, illustrated in Figs. 8 and 9, the control lever 22 is moved, as an incident of closing the cover 33, from its operative position (wherein it extends beyond the contour of the cabinet) into its other operative position instead of into its inoperative position as in my first embodiment. By so doing there is avoided the requirement for auxiliary means to look or obstruct the carriage against possible extraneous movements, since the feed nut l5 with the feed screw [4, which are mutually engaged when the control lever is in operative position, constitutes a looking or movementobstructing means for the carriage. It is, however, desirable that the control lever 22 be returned to inoperative position upon the opening of the cover in order to permit an immediate mounting of a record on the machine after the cabinet is opened. It is therefore a feature of my second embodiment to provide a coupling between the cover 33 and control lever 22 having a two-way action, this action being such that the control lever is moved into recording position (the operative position of the lever which is within the cabinet) as the cover is closed and into inoperative position as the cover is opened.

The phonograph and cabinet of my second embodiment may be of the general form of my first embodiment. In the present instance, however, the inter-eoupling between the cover 33 and back rod 9 is dispensed with and a modified form of arcuate member 35 is employed having the reference character l9. Furthermore the standard I and the back rod 9 of my first embodiment are slightly modified, principally in that they now respectively appear without the opening 85 and the ridge 55; these elements are therefore now given the respective reference characters la and 9a. Other elements which are in all respects similar to the corresponding elements of my first embodiment appear with the same reference characters.

At the right end of the rod 8 there is provided the arm 5| (having the downward extension 5|), the arm 5| carrying the rightwardly extending pin 53. By reason of the coupling between the rod 8 and the control lever 22, a rocking of one causes a similar rocking of the other. Thus when the control lever 22 is in its upper or reproducing position, the pin 53 is in an upper position, but when the control lever 22 is rocked into its intermediate and downward positions, corresponding respectively to its inoperative and recording positions, the pin 53 is moved into intermediate and downward positions as shown in dash-dot lines in Fig. 8. I

The means for moving the control lever 22 into recording position as an incident of closing the cabinet comprises a curved track 69 provided on the end wall 4| of the cover. This track is arranged to engage the pin 53 and move it into its downward position to effect the recording condition of the machine as the cover 33 is moved into closed position. The track 69 may very conveniently bepart of the aforementioned arcuate member 10 which effectively pivotally connects the cover 33 to the standard 1a in a manner in all respects similar to that of my first embodiment, the arcuate member being provided throughout its length with the channelled portion 36 having the longitudinal slot 31 through which passes the shoulder screws 38, as heretofore described. This track is provided along the upper half portion of the member III as shown in Fig. 8, and is open to the left as shown in Fig. 9; the track is also offset to the right with respect to the channelled portion 36 so that the track will clear the arm The member 10 is secured to the cover 33 by spotwelding the bottom 69 of the track 69 to the end wall 4| of the cover, and by means of a lug H on the member which is secured to the end wall 41 of the cover also by spot-welding.

When the'cover 33 is fully open the pin 53 is disposed in front of the upper portion 69 of the track 69, the pin 53 then being free to move into its respective positions corresponding to the op-- erative and inoperative positions of the control lever 22.. The upper portion 69' of the track is, however, flared out so that the track 69 will engage the pin 53, as the cover is closed, irrespective of the position of the pin 53 in its path. Proceeding along the track 69 from the upper or flared portion 69 thereof, the track first corresponds in position to that occupied by the pin 53 when the control lever 22 is in inoperative position, and then curves inwardly to a position corresponding to that occupied by the pin 53 when the control lever 22 is in recording position. If this inward curving of the track 69 is completed at an intermediate position along the track (such as position P in Fig. 8), the remaining portion of the track may be a simple are about the axis of the cover. Thus as the cover 33 is closed the control lever 22 is moved into recording position irrespective of the position of the control lever in its path at the time the closing movement of the cover is started; and as the cover is opened the control lever 22 is returned to inoperative position. It is for the reason of returning the control lever 22 to inoperative position as the cover is opened that the portion of the track 69 immediately behind the flared portion 69 of the track is positioned to correspond to the intermediate position of the pin 58.

Although I have described and illustrated my invention in several embodiments, it will be understood that many other forms and modifications of the same may be employed without departing from the scope of my invention, which I undertake to express according to the following claims.
