Specification of Letters Patent.

Patented June 20, 1922.

Application filed December 26, 1917. Serial No. 208,777.

To all in 110m it mdfl/ concern:

Be it known that I, NEWMAN H. HOLLAND, a subject of the King of Great Britain, and a resident of \Vest Orange, Essex County, New Jersey, have invented certain new and useful Improvements in Phonogr which the following is a description;

This invention relates to phonographs, and in particular to business phonographs or dictating machines in which there is a combined recorder and reproducer .or'a single diaphragm co-operating with two-styli.

This application, inasmuch as it relates to the hereinafter described guard, is a continuation in part, of co-pending application Serial No. 831,695 filed by me April 14, 1914.

Great difficulty has heretofore been experienced in devising a practical efficient sound box which is suitable for both recording and reproducing. In recording it is preferable that the recording stylus be so mounted that very little pressure is exerted by it upon the record blank. The stylus must also be held against lateral movement. In reproducing, however, it is preferable to weigh down the reproducing stylus and to allow it lateral play so that it will follow the groove in the record and not jump therefrom.

An object of the present invention is to provide a construction in which a recorder.

and reproducer having the above characteristics are combined in a single sound box.

Another object of the invention is to provide a construction in which the sensitiveness of the instrument will not be impaired by reason of the use of a single diaphragm for both recording and reproducing.

Another object of the invention is to provide a construction which can be easily manipulated to shift from inoperative to either recording or reproducing position and in which the feeding device for moving the phonograph carriage relatively to the blank or record will be inoperative when the recording and reproducing devices are both in inoperative sition.

Another 0 ject of the invention is to provide an improved construction for moving the feeding device from inoperative t0 operative position and vice versa.

Another object of the invention is to pro vide a construction in which the elements of aphs, of.

the feeding device, usually a nut and screw, will accurately engage or mesh when the dewoe is moved to operative position.

Another object of the invention is to provlde a construction whereby the styli may be back-spaced when desired and also to provlde a construction which will prevent the removal of the record or blank from or the positioning of the record or blank upon the instrument when either stylus is in operative position, thereby reventing damage either to the record or b ank or to the styli.

My invention consists further in the details of construction and combinations of parts hereinafter more particularly described and claimed.

gure 8 is a view partly in horizontal section and partly in plan of a detail of construction shown in Figure 5.

In the embodiment of the invention here illustrated a. carriage or support 1 is mounted upon a usual phonograph frame 2 and is arranged to be moved upon

suitable guide rods

4 and 4 upon the frame longitudinally of a record or blank 3. The carriagel has a substantially annular portion. 5 provided with an opening 6 in which is removably mounted a sound box body 7 having a neck 7 and a depending flange 7 The sound box body has a projecting portion 8 which is provided with a depending lug 9 fitting in a recess 10 at one side of the annular portion 5. A forked link 11 is pivoted at one end to the depending lug 9 and at its forked end embraces a tube 12 slidably mounted within the neck 7 and pivoted to the link. The tube 12 is movable upwardly and downwardly within the neck and allowed a limited amount of play. The lower end of the tube below the body of the sound box is provided with a horizontal flange 13. One side of the flange 13 has a depending portion 14 provided with lugs 15. Arms 16 are pivotally connected to the lugs and have fixedly attached thereto a light frame 17 supporting a diaphragm 18 and provided with a central opening 19 having a surroundin flared portion 20. Communication is made between the diaphragm and the tube 12 by means of a tube 21 havin a head at its lower end engaging the flare portion 20 of the opening and providing a universal 'oint. The tube 21 is slidably mounted within the tube 12. Suitable retaining means 22 comprising an angular piece as shown in Figs. 1, 2 and 3 is fixed to the top of the diaphragm frame 17 and extends over the head ofthe tube 21 to keep the same in position relatively to the flared opening of the diaphragm frame.

A post 23 is pivotally mounted between this horizontal flange 13 and a horizontally extending part 24 of the depending portion 14 which is secured to the flange 13. The

post 23 is provided with a ledge 25 which.

co-operates with a pin 26 connecting the arms 16 and limiting the downward movement of the diaphragm frame 17. A floating wei ht 27 is pivoted at 28 to the lower end of t e post 23 on an axis at ri ht angles to the pivotal axis of the post. T e weight is located below the diaphragm and is provided with a central slot 29 through which can project a stylus 30 fixed to the central portion of the diaphragm. The stylus 30 comprises a U'shaped member 30* having a stylus pin 30 attached to the central portion thereof, while the ends of the member are attached to the diaphragm; The stylus 30 is for recording and is in operative position when located as shown in Figure 1.

A stylus lever 31 provided with a reproducing stylus 32 at one end is pivotally mounted intermediate its ends upon an axis 33 parallel with the axis or pivot 28 of the weight 27 within the slot 29 of the floating weight. The stylus 32 is on the lever 31 at the end thereof remote from the pivot 28 of the weight 27 and the arm of the lever 31 adjacent to the pivot 28 is heavier than the other arm whereby when the parts are in the position shown in Figure 1 the stylus end of the lever will engage the weight as shown at 34 and the opposite end tend to hang down. The last mentioned end of the stylus lever is provided with a hook 35 which extends within the U-shaped member 30 and in one position as shown in Figure 1 is out of engagement therewith and in another position, as shown in Figure 2, is in engagementtherewith, as will be more fully described hereinafter.

The flange 13 has a depending tongue 36 having a vertical slot 37 therein into which projects a pin or adjustable screw 38 attached to the floating weight. This tongue prevents extreme lateral movement of the floating weight around its vertical axis and allows it to be moved up and down. At one side of the depending tongue 36 is a shoulder 40 with which engages a projection or tongue 41 fastened to the diaphragm frame 17, limiting the downward pivotal movement of the latter relatively to the tube 12. A vertically extending lug 42 is fixed to the frame 17 to limit by engaging the flange 13 r the upward movement relatively to the tube 12. The floating weight 27 is provided at one side of the pin 38 with a lug 43 having a V-shaped groove 14 upon the lower side thereof for a. purpose more fully disclosed hereinafter. I have provided means for controlling the positions of the styli and for this purpose I have keyed upon the guide rod l which is rotatably mounted in suitable hearings, not shown. upon the phonograph frame a lever or controlling means 45 movable with the carriage and comprising a sleeve 46 on the rod and a handle 46 having a hub encircling and secured to the sleeve. Rotatably mounted upon the sleeve 46 at each side of the handle 46, are

dogs

17 and 48. These dogs are provided with noses 19 and 50 adapted to engage and disengage the lower portions of the tongue or projection 11 and the grooved lug 43 allowing the body member 7 to be lifted out of its support without first disconnecting the controlling means. The nose 50 is provided with a raised shoulder 51 and a knife edge 52 engageable with'the groove 4 1. In order to normally cause the dogs to move upwardly into engagement with the floating Weight and diaphragm frame to hold them with the tube 12, in raised position, I have provided a pair of )ivoted arms 53 and 54 which are controlle by a spring 55 which urges them into engagement with the noses 49 and 50 of the dogs to hold the latter raised. This is clearly shown in Figure 3 where all the parts are in raised position.

Immediately above the noses 49 and 50 of the dogs, the hub of the handle 46 is provided with a lug 56 having a cross pin 57 projecting over and adapted to engage the tops of the dogs. When the lever is moved in one direction, for instance. counter clockwise looking at the figures, the dogs can be readily depressed so thatthe floating weight, the diaphragm frame 17 and tube 12 with its flange .can drop upon the record or blank substantially at right angles thereto with the recording stylus in position thereon, the weight supporting the tube 12 and connected parts on the record or blank and the diaphragm frame being movably mounted relatively thereto and exerting just the necessary pressure on the stylus 30.

In order to prevent the floating weight 27 from damaging the record or blank a ball or tracking device 58 projects from the lower surface thereof and is adapted to hold the weight away from the blank.

The arm 54, it should be noticed, is provided with a shoulder 59 intermediate its ends. A lug or cam 60 upon the hub of the actuating lever is so arranged that when the lever is moved to another position, for instance, to the position shown in Figure 2, the lug will engage the shoulder 59, moving the arm 54 away from its dog 48 to allow the floating weight only to drop towards the record or blank. It is preferable to provide suitable means for moving this dog downwardly automatically away from the weight when its arm is depressed as described above. To this end, collars 61 secured to the sleeve 46 retain the dogs in position against the hub of the lever. The collar adjacent the dog 48 upon its inner face, see Figs. 5 and 5, is provided with a groove 62. Within this groove is a coiled spring 63 attached at its upper end to the grooved collar and attached at its opposite end to the lower side of the dog 48. see Figures 5 and 5. This spring tends normally to move or urge the dog 48 downwardly away from the weight and exerts a force less than the force exerted by the spring 55 tending to elevate the dog. When the latter force is removed, the first will move the dog downwardly. It will, therefore, be seen than when the handle 46 is thrown to the position shown in Figure 2, the floating weight will be allowed to drop carrying with it the lever 31 and the hook 35 of the reproducin stylus lever 31 will then engage the recor ing stylus member 30' held in raised position, connecting the lever with the diaphragm and swinging its stylus end into engagement with the record. The lowered position of the floating weight relatively to the member 30, the upward pressure on the stylus 32 by reason of its engagement with the blank and the excess weight of the lever 31 maintain the stylus 32 in operative relation to the diaphragm when the parts are in reproducing position. This construction is one in which the reproducing stylus is entirely disconnected from the diaphragm when the parts are in recording position so that the sensitiveness of the diaphragm will be maintained at a maximum, as greater sensitiveness is required in recording operations. The recording stylus is mounted upon the independently movable frame 17 which is of a minimum weight so that the sensitiveness of the recording stylus will not be impaired by being unduly weighed down by superimposed mechanism. In reproducing, however, a greater weight is necessary. It is for this reason that I have mounted the reproducing stylus upon a separate heavier weight and provided means for detachably connecting the reproducing stylus lever to the dia )hragm, the connection being made automatically when the parts are moved to reproducing osition.

To center the lateral y movable weight as it is raised or lowered the lug 43 with its V-shaped groove engages the knife edge 52 of its co-operating dog, providinga centering device.

Rearwardly of the actuating lever 45 is an arm or supporting means 64 pivoted at its upper end 65 to the carriage and provided with a vertically arranged slot 66. To the lower end of the arm is attached a channel-piece or member 67 having an upturned portion 68 provided with an opening 69 in alignment with the slot. The piece 67 is adjustable along the slot 66 and secured to the arm by a nut 70. A guide pin 71 fixed to the carria e projects through said opening and slot. The arm is thus suitably guided and held steady and the piece 67 is held fixed relatively to the arm. A transverse plate 72 is pivoted at one end to the channel piece within the channel. This plate is provided with a half nut 73 constituting an element of the feeding device, and swivelled thereto by a bolt 74 (see Figure 4) extending at right angles to the plate. The channel piece limits the swivelling. A spring 75 coiled around the pivot of the plate tends normally to project the plate outwardly towards a feeding screw 76 which constitutes the second element of the feeding device and is mounted upon the. frame 2. Outward movement of the plate around its ivot is limited by means of a headed pin 77 which extends through a slot 78at the end of the plate remotefrom its pivot and is secured to the piece 67. spring 79 is interposed between the carriage 1 and the arm 64, encircles the guide pin 71 and tends normally to cause the half nut to engage the screw 76. By allowing the half nut to have a limited swivelling movement relatively to the plate and to yieldingly swing with the plate around an axis at one side of it and at right angles to the longitudinal axis of the feeding screw 76 suflicient play is provided to cause the half nut and screw to accurately mesh and insure instant feeding when moved into engagement with each other. In order to disengage the nut from the screw, a pin 80 is slidably mounted in the carriage frame and engages at one end the upper portion of the arm 64 and at its opposite end is provided with a head 81 having a depression (see Figure 3) and lying in the path of the rotating hub of the actuating lever 45. This hub between the handle 46 and lug 60 is provided with an anti-friction wheel 82 which engages the head of the pin and slips into the depression to move the pin to force the lower end of the arm 64 back, thus moving the half nut out of engagement with the screw and holding them out of engagement. A spring 83 is interposed between the arm (34 and pin 80 to normally keep the latter in the path of the wheel 82. The above controlling means for the feeding device and the feeding device are clearly illustrated in Figure 3 and it should be noticed that both the recording stylus and reproducing stylus are there shown elevated with the feeding elements disengaged.

A spring arm 84 is attached at one end to the central portion of the arm 64 and projects towards the record or blank. At its free end the spring arm 84 is provided with a brush 85 adapted to brush the remrd as the mechanism is fed along. The brush will be disengaged simultaneously with the disengagement of the half nut.

I have provided a device, a form of which is illustrated in Figures 5 and 8, for backspacing the carriage. This device is an improvement over the construction shown and described in Letters Patent No. 1,178.014 granted April 4, 1916 and in my copending application No. 918,892 filed February 16, 1914. As illustrated in said figures, the carriage 1 is provided with a hub 86 slidably mounted upon the uide rod 4 which is rotatable relative to said hub. One ortion of the hub 86 is provided with 'a cliamber or recess 87 in which is located the styli controlling means or lever 45 slidably keyed to the rotatable guide rod 4 for actuating the same and movable with the carriage. Another portion of the hub 86 has a second chamber or recess 88. A housing 89 is threaded into the hub 86 and opens into the chamber 88. A pin or element 90 is mounted within the housing 89 and projects into the chamber 88. In order to provide a safety means for a purpose more fully described hereinafter the in 90, for instance, may be normally held yleldingly projecting into the chamber 88 by a spring 91 interposed between the head of the pin 90 and the housing 89.

The projecting end of the pin engages a face of an annular cam disc or co-operating element 92 which is slidably mounted upon the rod 4 and moves along the same with the carriage 1. The inside diameter of this disc is slightly larger than the diameter of the guide rod 4 and into the central opening through the disc projects a radially disposer pin 93 which engages a keyway 94 extending along the guide rod substantially from one end to the other thereof. The controlling means 45 is similarly keyed to the guide rod 4 by means of a pin 95 thereon which also projects within the keyway 94. It will be seen that the pin 93 causes the cam disc to rotate with the guide rod whenevfer the trolling means 45 to be moved from the recording position to the reproducting position and back. in order that the backspacing device may be provided with means to cause back-spacing when the controlling means is moved in either direction the cam (lit-K 92. for instance, within the recess 96 adjacent to one end thereof may be provided. as shown. with a V-shaped nose or double cam surface 97 in the path of which the end of the pin 90 lies. A coiled spring 98 encircles the guide rod 4 and is interposed between the hub 86 and the cam disc 92 and tends at all times to move the cam disc into engagement with the pin 90.

The nose 97 is so arranged that when the controlling means 45 is rotated from its central or inoperative position to the reproducing position, the cam disc 92 will be rotated with the guide rod 4 and the nose 97 will engage the pin 90 which remains practically stationary relative to the guide rod. Owing to the fact that the opening through the cam disc is slightly larger than the diameter of the guide rod 4, the cam disc will be tilted and caused to bind or bite upon the guide rod, the resulting cam action between the nose 9? and the pin 90 causing the carriage to be moved bodily toward the left, looking at the Figure 5, slightly back-spacing the same. During normal operation of the backspacing device when the carriage is free to move the spring 91 will not yield sufficiently to prevent the back-spacing as the force necessary to move the carriage will be less than the force required to depress the pin 90.

As the controlling means 45 is moved from inoperative position to reproducing position as described above both styli will be out of engagement with the record and the half nut and screw of the feeding device will be out of mesh so as not to interfere with the proper operation of the back-spacing device. WVhen the controlling means 45 is returned from reproducing position towards the central or inoperative position the nose 97 moving in the reverse direction will again engage the pin 90 causing the cam to be tilted and to bite the guide rod, thereb moving the carriage back still further. t

will be seen then that the carriage 1 can be back-spaced twice by moving the lever from reproducing position to central position and then back to reproducing position, the nose 97 being the means which enables this to be done. This double movement has a distinct advantage because the back-spacing can be done very quickly and with the same means that controls the styli and elements of the feeding device. A severe strain would be put upon the pin 00 and cam disc if the former were fixed to the carriage and if, by chance, the operator, when actuating the lever 45, should hold the carriage 1 or hub 86 in a way to prevent its sliding movement along the guide rod. It is for this reason that the pin 90 is allowed to yield when the carriage is held by the operator, thereby preventing any tear or strain upon the operating parts and providing a safety means. on the other hand, when the controlling means 45 is properly actuated. the spring 90 is of suflicient strength to act as an abutment causing the carriage to backspace. As soon as the cam nose 9? moves out of engagement with the pin, the cam disc will assume its original position by reason of the engagement of the spring 98 therewith.

From an inspection of Figure 4 it will be seen that the recording stylus is slightly in advance of the reproducing stylus so that after a record is made the reproducing stylus can be lowered into operative relation to the record engaging the sound grooves at point spaced inwardly from the forward part thereof. At the same time the repro during stylus will be back-spaced by the device above described, so that a material part of the record can be reproduced at any time desired without bodily sliding the car riage back by hand. It will, therefore, be seen that if it is desired to reproduce any of the matter that has just been recorded. all that is necessary is to shift the controlling means 45 from recording to reproducing position when the reproducing stylus will be back-spaced slightly and by reason of the fact that it is spaced normally slightly back of the recording stylus a considerable part of the record can he then reproduced. On the other hand. during reproducing, if. the operator should fail to understand fully any part of the record and for this or any other reason should desire to have any part of the record repeated, it is only necessary to shift the controlling means 45 back and forth more or less rapidly between repro during and central positions wheretlv the carriage can be easily and quickly back spaced to the desired amount.

My back-spacing device is very durable and serviceable and does not become easily damaged or disarran ed by reason of careless operation. Bac spacing can also be done twice as fast as with the device described in the patent above mentioned.

I have also provided a guard to prevent the record or blank from being taken off of or positioned upon the instrument when the latter is in either recording or reproducing position. This guard comprises a means or device movable into the path of the record or blank when the reproducing stylus is in position on the same and a separate means or device movable in the path of the record or blank when the recording stylus is in position thereon and preferably operated. by the first mentioned means. For this purpose an arm 99 is rigidly attached to one end of the guide rod 1 and is of sufficient length to project into the path of the record when. the guide rod is rotated by the controlling means 45 to reproducing position as shown in Figure 2. The arm 99 prevents the removal or the positioning of the record or blank when the instrument is in reproducing position. Pivotally connected at 100 to a screw guard 101 is a lever 102 having arms 103 and 104. The arm 103 is adapted to extend into the path of the record or blank as shown in Figure 1 when the instrument is in recording position and prevents the removal or positioning of the record or blank as long as the instrument remains in this position. In order to move the lever 102 into the path of the record or blank th arm 99 is of such length that it will engage the arm.104 of the lever 102 when the instrument is moved to recording position and will move the arm 103 of the lever in front of or into the path of the record or blank as shown in Figure 1. \Vhen the parts are in the neutral position shown in Figure 3. both

arms

90 and 102 will be in such position that the record or blank may be easily removed or positioned without interference therefrom. Tn this position both the recording and the reproducing styli are elevated and out of engagement with the record or blank. A spring 105 normally tends to keep the lever 102 out of the path of the record or blank.

The guard is especially adapted for the particular construction of instrument herein described, but is also of general application and is an improvement upon the invention described in Letters Patent No. 875,309 granted December 31, 1007. This guard is simple in construction and can be easily applied to instruments of the character described and prevents the removal or positioning of the record or blank, except when the instrument is in inoperative position. so that the record or blank or styli can not be damaged.

In my construction the sensitiveness is greatly increased, the parts have been much simplified, while the reproduction is very clear. Furthermore, the instrument can be quickly adjusted for recording or reproducing by swinging the lever to the extreme positions. When it is desired, however, to remove the record or blank or to place the same in position upon the instrument, the lever can be moved to vertical or intermediate position, as shown in Figure 3, when the parts will be raised out of the way and the half nut will be disengaged.

It is to be understood that my invention is not limited to the embodiments and features specifically shown and described herein, but that such features and embodiments are subject to changes and modifications without any departure from the spirit of the invention.
