Renewed July so, 1932 16 Claims. (Cl. 274-21) This invention relates to, phonograph machines, and in a more specific aspect to machines for recording or reproducing dictation. or both, such machines being known as commercial phonographs.

. An object of this invention is to provide means associated with the power operated driving means of such machines for mechanically performing functions heretofore performed by force extraneous to said driving means.

Another object-is to provide means whereby the operation of said mechanical function-performing means may be manually controlled, and

preferably this may be done from from the machine.

A further object is to provide an improved back-spacer mechanism for phonographs.

A still further object is to provide a backspacer. mechanism for phonographs which is opzb, 'erated by a part of the machine which constantly operates while the machine is in use, said backspacer mechanism being controlled preferably from a point remote from, the phonograph.

Another. object of this invention is to provide a manually operable rem ely located controlling device and a brac t therefor, which device may be easily det ched by handjrom the bracket which itselfmay be detachably connect ed to a typewriterframe.

Another objectoi this invention is to transmit the power manually applied to the manually opa point remote l5 erable controlling device to the mechanismwhich it operates on" the frame of the phonograph by a flexible connection, such as an airhose.

Other features and advantages 'will hereinafter appear.

In the accompanying drawings, which illustrate the present'invention in the form at present preferred Figure 1 is a view of a typewriting machine, and a phonograph of thetranscriber type located along side of the typewriter, the connections between the manually operable part on the typewriter and the phonograph being shown.

. Referring to Fig. 1, the machine shown in the accompanying-drawings comprises a base 10 containing a driving motor -11. As may best be seen in Fig. 2, the top 01, the casing is constituted by a table 12 having formed: integral therewith a housing 13 for supporting a mandrel 14 adapted to carry a record 15, which is to be reproduced.

The table 12 also has vertical standards 16 and 17 between which there is mounted a guide rod 19, (Fig. 12) adapted to control the traveling movements of a sound-box carriage 20 over a record 15 to reproduce the sound recorded upon the record, which traveling movements forwardly are controlled by the rotation of a feed-screw 21 which is engaged by a nut 21 mounted on the carriage 20.v Again referring to Fig. 2, the mandrel 14 is mounted upon a shaft on whose end a movable clutch member 22 is provided. This clutch member 22 is adapted to cooperate with a clutch member 23 secured to a pulley 24 which is constantly rotated while the machine is in use by the motor' 11 through a belt 25. a

In using the machine, the clutch member 22 is moved into and out of engagement with the continuously operating clutch member 23 by the user of the machine through mechanism not shown and of no particular consequence in connection with the present invention. Suflice it to say, that even when the clutch member 22 is disengaged from the clutch member 23, the pulley 24 continues to operate, being at all times positively driven through the belt 25 by the motorll.

It frequently occurs in the use of the machine that the operator desires to revert to a portion of the record just passed to verify the transcription or to, again listen to something which was not entirely clear. To facilitate this, transcribing machines have heretofore been, and the machine of this invention is, provided with back-spacing means comprising a lever, 26 having -.a hub '27 supported by the sound-box carriage 20 and car-' rying a pawl 28 adapted to cooperate with 'a toothed rack 29 supported by the standards 16 and 17 directly above the guide rod 19.

When the lever 26 is depressed, the pawl 28 engages the rack 29 and forces the carriage backs wardly, i. e. towards the left, in Fig. 2. The same operation also raises the nut 21? from the. feedscrew 21 to free the carriage therefrom for the.

back-spacing movement.

. Mounted in the carriage 20 is a sound-box 30 which, as usual, contains a diaphragm 31, -(see be raised from the record-surface during the Figs. 3 and 4) and a stylus 32 mounted in a pivoted lever 33 carried by a weighted support 34 pivotally mounted ona pivot rod 35 carried by a bracket 36 mounted on trunnions 37 for movement in a plane at right angles to the plane of movement of the support 34 on the pivot 35. The pivot 35 and the trunnions 37 permit the stylus 32 to have free lateral and vertical movements on the record within the limits of a guide 38 engaged by a pin 39 carried by the support 34. In accommodating itself to records of various thicknesses and to inequalities in the record surface, the

stylus 32 with its support 34 moves up and down onthe pivot 35, and to permit free tracking of the record they move horizontally about. the trunnions 37. v The stylus lever 33 is connected to the diaphragm 31 by a wire 40. a

In addition to the function above described, the

horizontal pivot 35 of the weighted support 34 'allows the. latter with the stylus lever and stylus to beraised from record-engaging position when desired. To do this, when it is desired to move the sound-box carriage a relatively long distance along the record, either forward or backward, or when it is desired to change records, the weight lever 34 is provided with a depending arm 85, see

. Figure 12, adapted to be engaged by an arm 86 'carried by a carriage release or sound-box conditioning lever 87. This conditioning lever is so ward end, its rearwardly extending arm 86 engages arm of the weighted support 34, and

4 raises the latter with the stylus from the record surface. At the same time, the arm 86 engages the upper portion 88 of the-feed nut 21', to disengage the nut from intermeshing relation-with 'the'feed screw 21. For more complete description of the backspacing mechanism, sound-box construction and actuating means for the locking lever 42, reference should be made to the patent to T. H. MacDonald, No. 1,030,740, patented June 25, 1912, and to the patent of the present appliarranged that when the operator raises its forlocated when the back-spacing operation is commenced, improved means are provided by the present invention for locking the stylus and its support 34 against lateral or free tracking movements with respect to the carriage during the back-spacing operation. This means, in the form shown, comprises a locking lug 41 carried by the pivoted bracket 36- on which the support 34 is mounted, and a movable locking device comprising alever 42 pivoted on a screw 43 mounted in the sound-box 30 and carrying a notched wheel ur 0211161 member 44 cooperating with the locking 118' depending lug 45 normally located in the range of an arm 46, (Fig. 12) pivotally mounted on the carriage 20 and actuated through a'spring 47 when the nut 21' is raised upon the depression of the back-spacer key 26. It will be understood that not only is the arm 46 actuated to bring the notched wheel on the locking lever 42 into engagement with the locking lug 41 when thefeednut 21' is raised by operation of the backspace lever 26, but that it is similarly actuated to perform the same function when the feed-nutzi' is raised by operation 87.

.With this form of device, the stylus need not of the sound-box control lever back-spacing movement, but is allowed to skid or glide over the surface.

It will be noted from an examination of Fig. 11. that the guide member 38 at its upper portion is V-shaped so as to centralize the weighted support 34 and the stylus 32 with respect to the sound-box each time the lever 34 is raised to its upper limit of movementby means of the sound-box conditioning lever 87 an operation performed when the stylus is raised to permit removal or replacement of records or when shifting the carriage by hand. This, centralizing movement of' the weighted lever 34 upon being raised could not be effected because of the engagement of'the locking lug 41 with the notched member 44, unless some provision were made to permit relative movement between the latter and the lever 42 which supports it. This is accomplished by the present invention by making -'the member 44 in the form of 'a notched wheel pivotally mounting it ,on the lever 42 and fric-' tionally holding the notched wheel 44 (Figs. 3 and 4) against movement during the back-spacing operation by a spring 46. The friction produced by this spring is sufficient to hold the wheel 44 against movement during back-spacing operation,- but insuiiicient to prevent centralizing movement of the weighted lever 34 when the latter is raised by means of conditioning lever 87. The lever 42 may swing by its own weight to inoperative position when the actuating arm 46 is; moved back by the return of the manuallyoperated lever 26.

. Since the person using the machine is usually located at some distance from the machine, re-

- ceivingthe sound from the sound-box 30 through a flexible tube 49, (Fig. 1) leading to hearing devices 50, it is sometimes inconvenient to reach forward to the machine to operate the back-spacer key lever 26. To avoid the necessity of doing this, the present invention provides means operated by the motor 11 for actually performing the backspacing operation and so arranged that this means can be controlled'from a typewriting machine 51 or other point remote from the phonograph by an easily operated device, hereinafter described.

The means operated by the motor 11. for actually performing the back-spacing'operation The locking lever 42 is provided with a the path of' the cams. It

comprises a universal bar or ball 52 Journalled in the standards 16 and 17 and normally underlying an arm 53 (Figs. 2 and 12) secured to the back-spacer key lever 26. Hence, when the bail is rocked the back-spacer key lever will be depressed and the carriage will be returned one step by the engagement of the pawl 28 with the toothed rack 29. The bail 52 extends through the standard 17 and has an operating arm 54 at its protruding end (see Fig. 5).

The power for operating the ball 52 may, in accordance with this invention, be taken directly from the motor 11, but preferably it is taken from the pulley 24 which is driven by the motor through the belt 25. For this purpose, the hub of the pulley 24 is provided with cams 55 adapted to engage an interponent156 (Figs. 5, 6 and 7) pivotally' mounted on a stud 57' secured in the standard 17. The interponent 56 is coupled with a control lever 57'by a pin-and-slot connection 58, and the lever 57 is provided with an antifriction roller 59 adapted to engage a flat surface 60 on the arm 54 secured to the bail 52. When the end 61 of the interponent 56 is in the path of the cam 55, the interponent will, by engagement with the cam 55, be rocked, rocking with .it the control lever 57 which in turn operates the ball- 52 through the .arm 54. This'operation would be repeated indefinitely so long as the end 61 were permitted to remain in the path of the cam 55.

However, the end 61 of the interponent 56 is not always in the path of the cam' 55, but is normally in the position shown 'in Fig. -6, out of is held in the latter position by a trip-lever 62 having a cam surface 63 arranged to be engaged by a lug 64 on the interponent 56. The trip-lever 62is pivotally mounted on a stud 65 and when released from engagement with the lug 64 by means hereinafter described, permits the end 61 of the interponent 56 to beswung into the path of the cams 55 by a spring 66carried by a stud 67 in the control lever 5'7. 'This pivotal or swiveling move-- ment of .theinterponent 56 is permitted by its loose mounting on the stud 57', and it is kept in coupled arrangement with the control lever. 57 during this swiveling movement by the pin-andslot connection 58 and the stud 67. I

After each operation of the interponent 56, it is automatically rendered inoperative by being moved out of the range of the earns 55 by the trip-lever 62, which returns to its normal position after the'lug 64 has been swung down and is thenin position to engage the lug 64 with'its cam surface 63 upon the rising movement of the lug which causes the interponent to be pivoted or swivelled so that its end 61 will be moved away from the cam 55.

Of course, if the trip lever 62 is held inoperative by any means, the interponent will 'n t be made ineffective or inoperative, and the ackspacing operation will be repeated step-by-step until the carriage 20 reaches the" limit of its movement, or so long as there are teeth on the rack 29 for the pawl 28 to engage.

While the cams 55.-and the interponent 56 operate the bail 52 t6 back-space the carriage, the bail, the interponent 56 and its control lever 57 are all returned, by a single spring 68a connected byihe arm 54 of the bail, to their normal positions controlled by an adjustable stop 68b secured to a bracket 68 embracing the standard 17. Preferably, a leather bumper 70 is mounted in the control lever 57 so as to reduce the noise of operation of the device.

Thus it will be seen that the present invention provides a back-spacing device operated by the power of the motor and one which may backspace the carrlage one step or any number of steps so long as the trip-lever 62 is held inoperative.

Referring .to the lower right-hand corner of Fig. 5, and to Fig. 8, for the purpose of controlling the trip-lever 62 from a point remote from the machine, the present invention provides a cylinder 71' mounted in the bracket 69 and having a piston 72 which has a pin 73 adapted to engage an arm 74 on the trip lever 62. When the piston is moved outwardly of t e cylinder by the pressure of air in a manner h reinafter described, the pin 73 rides on the arm 74 until it engages a dwell 75 on the arm which is its normal operated position, and in which position the upper end of the trip-lever 62 is disengaged from the-lug 64 on the interponent 56.

The cylinder 71 has secured thereto in communication with its interior a flexible tube- 75 whose other end is threaded into a'similar cylinder 76 (Figs. 1 and 9) carrying a piston'77 on whose end is,mounted a finger-piece 78, the arthrough the flexible tube 75 into the cylinder 71,

and this excessive air forces the piston 72 outwardly of the cylinder to operate the trip lever. The partaare held in these positions so long as the finger-piece 78 is held depressed, but as soon as the finger-piece 78 is released, the spring 79 returns it and its piston 77 to normal position creating a partial vacuum in the cylinder 41 which in turn .withdr'aws the piston 72 from engagement with the dwell on the trip lever whichallows'the trip lever to return by gravity to its normal position.

' In order that the manually operable control device comprising the cylinder 76, the piston 77 and the finger-piece78 may be securelymounted on a typewriter frameland yet be detachable therefrom, the piston 77 is mounted in a bracket (Figs. 9 and 10) having a U-shaped clamping portion 80 adapted to embrace a. part of the frame of the typewriter and to be clamped thereto by a set screw 81.

, To further permit the manually operable device comprising the cylinder 76, the{ piston 77 and finger-piece 78 to be easily and quickly detached from its support on the typewriter, the bracket is provided with a floor or base 82 and arms 83 adapted to encircle the cylinder. The arms 83 are spaced from each other'and extend sufliciently to permit the nipple 84 on the cylinder 76 to pass therethrough, and they are spaced from the floor or base 82 sumciently to permit the 5,

nipple 84 to be Locked under the arms 83 when the cylinder is partially rotated in either direction from the position .in which it was inserted into the bracket.

a pair oi 3 Thus it will be seen that the bracket, provided by the present invention, may be used on either the left hand or the right hand side of the typewriter, and no matter on which side of the machine it is used, the flexibletubing connection 75 may be arranged either to the right or left as desired. This simple detachable connection be-' tween the manually operable part 78 and the supporting bracket is extremely' advantageous since it enables the manually operable part to be quickly and easilyremoved from its supporton 15d the typewriter when it is desired to close the desk of the typewriter, forinstance, or for any other purpose. a Y
