The sound box tube 34, which supthe Bowden wire clutch control and arranged to ports the sound box 27, is connected by means strike a bell once each timethe clutch control is of a ball and socket joint and a pivot pin conoperated when the machine is in either neutral nection 36 with a tube 35 slidingly mounted within the casing 28. This connection gives the sound box a limited range of up and down movement in order that it may accommodate itself to record cylinders of various diameters, or to compensate for any eccentricity or runout of said cylinders. In Figure 3, these parts are shown in neutral position, in which relation a cam lug 37 on the sound box tube 34 rides upon an adjustable guide plate 38, raising the sound box to an inoperative position, with both styli out of engagement with the record cylinder. This conditioning is necessary in order to safely load and, unload the mandrel 15, and also to allow forward and back spacing of the carriage without marring the record cylinder surface, as would occur if either of the styli were left in engagement with the record.

In a similar manner, the sound box 27 is conditioned for recording when the control lever 21 is moved to the forward position, as shown in Figure 4, for in this operation the connecting link 30 moves the sleeve 29 forwardly within the casing 28, and by this movement the cam lug 37 moves out of engagement with the guide plate 38 and allows the recording stylus to engage the record cylinder. Also, by moving the control lever 21 to the rearmost position, as shown in Figure 5, the sleeve 29 is moved forwardly within the casing 28 and moves the pivotally connected sound box forwardly until the lug 37 rides out of engagement with the guide plate 38, and allows the reproducing stylus to engage the sound grooves on the record cylinder, when matter previously recorded will be audibly reproduced. This form of sound box control and construction is more fully described in the United States Patent to Bodine et al, No. 1,606,744, November 16, 1926.

When the machine is in operation the mandrel rotates while the carriage moves longitudinally thereof, in order that the stylus may cut or follow a spiral sound groove on the surface of the record cylinder. It is customary to provide a clutch for starting and stopping rotation of the mandrel shaft and feed screw, so that the operator may instantly control the operation of the machine so as not to use up space on the record cylinder should he pause in his dictation. The clutch mechanism shown herein comprises the toothed hub 39 of the driving pulley 1-7, and

a single tooth clutch disc 40, attached to a rod 41 extending forwardly within a hollow portion of the mandrel shaft 14. This rod is connected with a clutch collar 42 longitudinally movable upon shaft 14 by means of a cross pin 43 which passes through a suitably slotted portion of shaftv 14 (not shown). A clutch operating yoke 44 is pivotally mounted on a pin 45 and is provided with two engagement members 46 fitting within a groove 47 of the collar 42. A flat spring 48 fixed to the top of the main frame and extending through an aperture 49 in the side of the housing, yieldingly engages the underside of a horizontally extending arm 63 of the clutch shifting yoke and tends to move the yoke in a clockwise direction about the pin 45 normally to keep the clutch disc 40 out of engagement with the toothed hub 39 and thereby permit free rotation of the driving pulley (see Figure2).

The clutch is control-led by a Bowden wire 50 which is connected to a boss-13k on the back of the housing 13 by means of a coupling 51, and extends to a mouth piece handle 52 where it is operatively related to the push button 53. The Bowden wire 50 comprises an inner. member 54 (see Figures 1 and 3) secured by a" pin'connection to a nipple 56 threaded in the boss 13' and held there by means of a lock nut 57. An outer Bowden wire 58 is connected, at one end, within the handle 52, in such a manner as to permit of its being moved relatively to the inner member by means of a finger piece 53. The other end of said outer member is connected to a plunger 59 longitudinally movable within the nipple 56. The inner end of the plunger engages one arm of a bell crank lever 60 pivoted on a pin 61 within the housing. The other arm of the bell crank lever in its pivotal movement engages the upper side of a shelf 62 offset from the arm 63 of the clutch shifting yoke. In operation, the yoke is swung on its pivot upon actuation of the push button 53 mutually to engage the clutch members and establish driving relations between the pulley 17 and the mandrel shaft. During this operation the outer member of the Bowden wire moves relatively to the inner member; the plunger 59 swings the bell crank lever 60 to depress the arm 63 of the yoke structure, which results in throwing in the clutch. When the button is released the parts are returned to stop position by the spring 48. The feed screw 25 is rotated when the mandrel shaft is set in motion by means of any suitable system of gearing, disposed within the house. As this gearing is common to many forms of dictating machines, no further description of it will be given herein, nor is it thought necessary to complicate the drawings by the addition of gearing pitch lines.

An ejector is provided for moving the record cylinder from the mandrel. In its present form it comprises a plunger 64 slidably mounted within the housing 13 for movement longitudinally of the machine. The operating end of the plunger has a head 64', so shaped and disposed as to pass by the flange 65 of the mandrel and to engage the inner end of the record cylinder 16 when the plunger is advanced. The other end of the plunger is fixed to an upstanding arm 66, forming part of a link 67. The link extends longitudinally of the machine beneath the base of the frame and terminates at a convenient point adjacent the end of the mandrel, where it has pivotal attachment to a transversely disposed lever 68 by means of a screw 69. The lever 68 is fulcrumed upon a stud 70 at the rear of the machine and at its forward end is provided with an upwardly extending portion 71, forming a finger piece by means of which the lever may be operated. This finger piece extends through a slotted plate 72 covering a suitable opening 73 left in the casting forming the base 10. The ends of the slot in the plate '72 serve as stops for limiting the movement of the lever.

The ejector parts just described are normally held retracted by means of a spring 73 interposed between and connected to the link 67 and the lever 68 at points adjacent to the screw 69, in which position the ejector is kept out of engagement with the record cylinder.

Novelty is not claimed for the features of the dictation machine hereinbefore described, and only such detail has been presented as will give a ready understanding of the present invention and the structural and functional relation thereof to the other parts of the machine, as will now be described. In giving dictation to a machine, the operator may, at times, desire to turn back and listen in on portions of his recorded dictation, in which case the sound box control or ring lever will be thrown into reproducing position. He might then forget to return the parts to recording rotation of the mandrel shaft.

position before resuming his dictation and only discover subsequently that the machine was improperly conditioned and his efforts wasted. Or he might-inadvertently allow the ring lever to remain in neutral position, after placing a record cylinder upon the mandrel, and then dictate for some time before learning that nothing had been recorded.

The present invention provides a simple means for warning the operator that the machine is not properly conditioned for recording wheneverthe ring lever is in neutral or reproducing position. The means comprises a simple bell trip arrangement adapted to sound a single warning signal on a bell should the starting button be pressed while the control lever is in either neutral or reproducingposition. This means comprises a bell 74 mounted upon a stud 75 on the side of the standard 11. and a bell hammer '76 having spaced bearing members 7'? and 78 pivotally supported upon the carriage guide rod 20. Bearing member 77 is provided with an upstanding offset finger 79 overlying a portion of the Bowden wire plunger 59, in a position to be engaged by a trip nut or abutment 80 threaded upon said plunger.

Normally, when the machine is in neutral or reproducing position, the position of the bell hammer 76 and abutment 80 is as shown in Figure 5. However, when the operator depresses the button 53 to engage the clutch and start the machine, the outer member 58 of i the Bowden wire and plunger 59 move to the left, as viewed in Figure 5, and the abutment 80 engages the side of the offset finger l9 and upon further movement turns the hammer about the guide rod 20 against the tension of a spring 81, as shown in Figure 6. When the Bowden wire member 59 has been moved a certain distance, the under surface 82 of the offset finger rides over the abutment and trips off behind it, in .a manner which will be clearly, understood by inspection of its position in Figure 6. The striker end 83 of the bell hammer then is drawn sharply against the bell to sound a single signal, thus giving the operator an effective warning that the machine is not properly conditioned for recording. Preferably this warning is sounded before the Bowden wire has been moved a sufficient distance to cause the engagement of the clutch members and start Adjustment is provided as will be described later, for determining how long before the clutch engages, the warning will be given.

When the button is released to stop the machine and the Bowden wire plunger 59 returns to its original position, the tapered side 80 of the abutment 80 lifts the finger 79 until it is clear of the abutment 80, when it drops again to the position shown in Figure 5. This lift of the hammer parts is made possible by having the bearing opening 84 in the bearing member 78 of relatively larger diameter than the similar openingin the bearing member 7'7, and also considerably larger than the rod 20. The relatively large aperture serves another purpose, as will be seen later.

As the bell trip or warning device is operative solely towarn the operator when the machine is in neutral or reproducing position and therefore not properly conditioned for recording, means must be provided for rendering such operation automatically selective. This means comprises a cam plate 85 pivotally mounted upon the carriage guide ,rod 20 and having a lobe 86 projecting from the upper part thereof in a position to engage a second finger, or lug, 87, offset from a point on the hammer bearing member '78 when the machine is conditioned for recording, and thereby to lift the offset finger '19 out of the path of the abutment 80. As it is a necessary feature of this device that its actuation may be effected with its carriage occupying any point in its path of travel, a bail 88 is provided for actuating the cam plate 85, which bail is mounted at one end in the lower end of the cam plate and at the other end in a plate or hanger 89, supported upon the rod 20 at the opposite end of the machine. To move the bail 88 and cam plate 85 to any one of the three positions shown in Figures 3, 4 and 5, a link 90 is provided, connected at one end with the sound box sliding tube link 30, as by the pin 91, and extending rearwardly and downwardly to a point of connection by means of a stud 92 with the upper end of a lever 93, pivotally mounted on a stud 94 upon the side of the carriage guide support 95. The lower end of said lever occupies an operative position relative to the bail 88, which is yieldingly maintained in engagement therewith by means of a bell crank lever 96 having a longitudinally disposed arm 97 positioned above the base 10, and a transversely disposed arm 98 situated below the base, both of which arms are aflixed to a pin 99 extending downwardly through said base. As may best be seen in Figure 1, this bell crank lever is nor mally held in contact withthe bail 88 by means of a tension spring 100 fastened at one end to the transverse arm of the bell crank, and at the opposite end to a stud 101 on the underside of the frame. The bell crank is provided for a purpose later to be described.

It will readily be seen that when the operator manually moves the sound box control lever 21 from the neutral position shown in Figure 3, forwardly into the recording position shown in Figure 4, the links 30 and 90 will serve pivotally to move the lever 93 and swing the ball 88 and cam plate 85 into the position shown in Figure 4. As the cam plate advances the lobe 86 engages the offset finger 87 and raises the finger '79 out of the path of the abutment nut 80. In this position of the parts, actuation of the starting mechanism by means of the button 53 and Bow-' den wire 50 will not sound an alarm signal to warn the operator, who may proceed with his dictation with the assurance that the machine is properly conditioned for recording. When, how ever, the sound box control lever 21 is moved rearwardly into the neutral position to raise the styli out of contact with the record cylinder, the lower end of the lever 93 is drawn back, permitting the parts to return, under the influence of spring 100, to the position shown in Figure 3. As the lobe 86 of the cam plate 85 is now removed from engagement with the finger 87, the finger 79 returns to its operative position relative to the abutment 80v thus resetting the device for operation should the operator depress the Bowden wire button 53 to start the machine. Likewise, when the operator moves the control lever 21 to the reproducing position in which the reproducing stylus is brought into engagement with'therecord cylinder, the parts assume the position shown in Figure 5, where the lobe 86 is still out of engagement with the offset finger 87 and the bell hammer trip 'device is set for actuation by the starting mechanism.

With the arrangement of parts just described, it will be apparent that the present invention provides a simple bell hammer trip warning device which is operative when .the machine is in either neutral or reproducing position, but which is inoperative when the machine is in recording position. It should be noted that there is an adjustable relationship between the bell hammer 76 and tripping device, for as shown in Figures 4 to 6 inclusive, the plunger 59 is threaded and.

the abutment nut 80 is movable thereon in order to effect the bell trip-off at any desired point in the manipulation of the clutch control. A lock nut 103 serves to maintain the abutment in its position of adjustment. Preferably, the bell trip is timed to occur just prior to the actual operative engagement of the clutch members.

It should be particularly noted that the bail 88 of the present invention serves another very useful purpose. As is best shown in Figure 1, the bell crank 96, which is at all times in operative engagement with the bail 88, is provided with a pin 104 which rides in the V-shaped aperture 105 formed in a latch lever 106 pivotally mounted by a stud 107 on the underside of the base. The latch lever 106 is provided at its outer end with a hook or catch 108 adapted to swing into the path of a pin 109, projecting downwardly from the ejector lever 68. This arrangement of parts is such that the ejector may be operated only when the machine is in neutral condition, that is, when both the recording and reproducing styli are out of engagement with the record cylinder, and positively locks the record ejector against operation when the machine is in either recording or reproducing position.

As shown in Figure 1, the pin 104 in the end of the bell crank arm 98 is in the position it assumes when the sound box control lever 21 is in neutral position, and when so positioned, the pin being in the high point of the inverted V- shaped slot 105, holds the latch lever 106 in such a position that the hook 108 clears the pin 109 on the ejector lever 68 and does not lock the record ejector, but when the control lever is' moved into either its recording or reproducing station, the pin 104 travels to one or the otherof the low points of the inverted V slot 105 and causes the latch lever 106 to lock the ejector lever and positively prevent operation of the ejector.

It will thus be seen that the bail 88 of the present invention serves a twofold purpose, namely, the conditioning of the bell trip warning device and of the record ejector lock, in predetermined relationship with the stationing of the sound box control lever 21, regardless of the position of the carriage 18 longitudinally of the machine.
