Specification of Letters Patent.

Patented April 9, 1 907.

Application filed J mm 6, 1906. Renewed September 27', 1906. Serial No. 336,499. I

To all whom it may concern:

Be it'known that I, GEORGE M RIN, a citizen of the United States of America, and a resident of Habana, Cuba, have invented a new and Improved Tele aphone, of which the following is a full, 0 ear, and exact description.

My invention relates to telegraphones, and more particularly to apparatus for enabling the so-called voice-currents" to be generated in a wire or line by means of a magneto member havingthe form of a disk.

My invention further relates to means for enabling one or both sides of the disk to be used as desired.

My invention also relates to certain details and other parts being partly broken away.

Fig. 3 is an enlarged vertical section uponthe line 3 3 of Fig. 2 looking in the direction of the arrow and showing the means for reversing the direction of travel of the sliding carriage carrying the magnets 40. Fig. 4 is a'horizontal longitudinal section through the magnets and the mechanism for sup orting the same upon opposite sides of the sk 23, and Fig. 5 is a diagram of the wiring for ener gizing the magnets.

A casing 6 is mounted upon a base and is provided with a comparatively long bracket '8, secured in position by a fastening 9. Another bracket v10 is mounted directly upon the casing. These two brackets su port a stationary shaft 11-. The bracket 8 1s providedwith an extension 12,- and mounted.

' oppositely to this extension and rigidly se- ,7 cured to the casing 6 is a bracket 13. Twin shafts 14 15. are threaded and revolubly mounted u n the extension 12 and the bracket 13, eing disposed parallel with each other, as'indicated in Fig. 1. These twin shafts are provided with gears 16 17., mounted rigidly thereupon and -meshing .with each ot er A bevl-ge'arlS is mounted upon the shaft '15 and serves toturn the same. This bevel-gear meshes with another bevelgear 19, the latter being rigidlyconnected with a revoluble spindle 20. has a reduced portion 21, upon WizC-ll is mounted a mushroom-head 22, and engaging the latter is a revoluble disk 23, made of steel or other magnetic material and held rigidly against the mushroom-head 22 by means of a clamp 24, secured in place by a-revoluble screw 25. By this arrangement the disk 23 is readily removable from the"- mushroomhead 22 and is also adjustable in relation thereto, and yet when fixed in position is 7'0 quite firmly connected with the'spindle 20,

being moved positively by the rotation thereof.

A bearing-sleeve 26 is slidably mounted u on the stationary shaft 11, and connected with the ends of this bearing-sleeve are milled nuts 27 28. The nut 28 secures a plate 29 rigidly to the sleeve 26. This plate 29 is provided with a lug 30, which loosely engages-the casing 6 and is slidable relatively 0 thereto.

A rocking shaft 31 is provided with ,a slotted arm 32, dependingtherefrom. This slotted arm engages a projection 33,'extend ing upwardly from a rocking head 34, the 5 latter being connected by a pivot 35 with the late 29. The head 34 is provided with ongitudinal threads 35 and is also provided with an arm 36, carrying a weight 37.

A shelf 38 is mounted rigidly upon the cas- 9o ing 6 and is adapted'to su port the arm 36, and consequently the weig 1t 37, as indicated I by dotted lines in Fig. 3. The rocking head 34 isadapted to'occupy the two positions indicated, res ectively, by'full and dotted lines in Fig. 3. en the head 34 is in the position indicated by full lines, the threads 35 engage the threaded shaft 14, and when the head .34 occupies the position indicated by dotted lines the threads in question engage the 1 threaded shaft 15. 'The shafts'14 and 15 are similarly threaded, so that the revolution of the shaft14 tends to carry the head 34 toward the center of the revoluble disk23, whereas thatof the shaft 15 tends-to carry the head 5 34 in-the contrary direction-that is, away from the center of the disk 23. The rocking shaft 31 is'provided with a knob 31*, whereby this shaft may be rocked by hand, so as to move the arm 32, and this rock the head 34, I I

as indicated by full and dotted lines in Fig. 3.

Two magnets 39 40 are provided with tubu- This spindle 6o lar soft-iron cores 41 and annealed pole-pieces Q 43 44, of soft iron,"these pole-pieces being pointed and adapted to engage the opposite idly with the magnets 39 40. These magnets as indicated in Fig. 5.

' ing-sleeve 26 by means of a plate 26. This justable'thumb-nut 59the bearing-sleeve 57 maybe clamped rigidly in position, as indiw i1ichIcall-acarriage.f

upon one or both of its faces with a magnetic record is mounted in position, as described.

I both of its faces an invisible spiral record-line,

ed upon a vertical bearing-sleeve 57, which is free to swing slightly upon a pivot- 58, the

faces of the magneto-disk 23, as indicated in Fig. 4. Insulating-plates 45 46 are connected rigare connected with wires 47 48, 49, and 50,

The wires 49 and 50 are connected in parallel with each other with reference to a linewire 51, which is provided with a handconnected in parallel with each other with reference to the line-wire 52, the latter being provided with a hand-switch 52 Springs 53 54 of metal support the magnets ets 56 of insulating material, and are supportlatter being rigidly connected with the bearplate coacts with the plate 29 in supporting the rocking shaft 31. By'means of an ad-.

cated in Fig.1, with any desired degreeiof play'that is,it may be adjusted by means of the thumb-nut 59. The tubular sliding member 26, together with the plates 26 29 other parts carried-by it, constitute a part The motor mechanism, of which the spindle 20 is a part, is wound in the usual manner by means of a crank 59. This motor mechan' ism forms no part of my invention and is therefore omitted. l

Lhe operation of my device is as-follows: The disk 23 having been previously provided The preparation of the diskmay, be made by means of the, apparatus above described, in which event the magnets 40 are energized from a telephone-line, or at least from a tele' phonic receiver. .The disk'being of steel or other magnetic material acquires upon one or different portions of which are magnetized to different extents and in different-senses in thesame manner as a wire, cylinder, or other ma neto member used the Poulsen tele rap one. The diskispreferably smooth. Motion being communicated by'the spindle 20 to the bevel-gears 19 and 18, the twin screwshafts 14 and 15 revolve in opposite direc trons. The arm 36 is. now raised into the position indicated by dotted lines in Fig. 3 and rested upon the adjacent shelf. This-is done by the-operator graspin the milled' head 31, and thereby manipu atin the shaft 31. The rotation of the scrw-sha 15 while the latter is engaged by the head 34 causes-the niatically "carriage to travel toward the center of the disk 23, and consequently carries the magnets 40 from the edge of the disk and toward the alternating currents are generated in both magnets 39 and 40 if the disk 23 has both of If, however, only one face of the disk 23 is provided witha'record, only one of the magnets 39 40 is energized.

The disk 23 may be provided u on one of its faces with a part of a recor say one half of a speechand the opposite face may be provided with acontinuation of the same record-say the other half of the same speech.- Inthis case I desire that only one of the pole-pieces be magnetized while the carriage and magnets travel in one direction, the other pole-piece being in turn energized while. the magnets and carriage travel in the opposite direction. The magnets can be thrown out of or into circuit inde e'ndently of each other by opening and c osing the hand-switches 51 and 52. When both pole-pieces are energized simultaneously, the electric impulses set up in the magnets 39 40 are stronger than when only one is energized. If the left-hand side of the disk is to be used, (according to view shown in Fig. 4,) the circuit is as-follows: wire 51', switch 51, wire its. faces provided with identical records.-

49, solenoid 39', wire 47, Wire 52. If both sides of the disk are to be used, the circuit, is as follows: wire 51, switches 51 and 52*, wires 49v 50 in parallel, solenoids 39 40, wires 47 48, wire 52. Where it is desired to utilize both sides of the disk for'a continuous rec ord, it is of course necessary that the mag nets shall first travel from the edge to the center of the disk and then travel back from the .center to the edge of the said disk. This is accomplished automatically by means of the mechanism indicated in Fig. 3. When the arm 36 rests-upon the shelf 38, the rotation of the threaded shaft ,15 drives the carriage,

and consequently drives the magnets 39= 40 toward the center of the disk 23 The end of the shelf 38'nearest the center of the'disk being reached, however, the arm 36 drops by virtue of the weight 37, as indicated-by full lines in Fig. 3, and the head 34 is thus autothrown out of engagement with the threaded shaft 15 and into en agement with the threaded shaft 14. This shaft thereupon immediately returns the carriage to its original position, the hand-switches 51 52 servlng meanwhile to open the circuit through one of the ma ets and to close the circuit through the ot er. If at any time the operator desires to restore the parts to the position indicated by dotted lines in Fig. 3, he grasps the knob 31*, moves the carriage toward the spindle 20 until the carriage reaches the limit of its stroke-that is, until it reaches a point where the arm 36 can missv the shelf'38 and thenturn s the knob 31 so as to move the arm 32 and the projection 33,

thereby causing the-head 34 toclear the screw-shafts 14 and 15. The knob 31 being held momentarily in this position, the car; riage may be moved by hand to any desired point along its stroke or, if'at the end of a stroke, may be retracted and brought back to its original starting-point.

When the operator desires to use one side of the disk for. instance, the right side according to Fig. 4-he opens the switch 51 and closes the switch 52. Similarly, when he desires to use the otherside of the disk, he closes the switch 51 and opens the switch 52*, .If therefore it be desired to utilize the two sides of the disk'in successionas, for

instance, if one side of the disk contains one half of his speech and the other switchcon- 'tains the other halfthe operator causes the carriage to travel first from the outer circumference to the center of the disk, meanwhile opening the switch 51, and closing the switch 52*. The direction of travel of the carriage vnow being reversed, he closes the switch 51 and opens the, switch 52".. In other words, when the carriage is traveling v one direction relatively to the center of the disk one of the solenoids is energized, and-in traveling in the opposite direction the other,

magnet is energized. By. this arrangement the operator is'ena'bled to utilize both sides of the disk, theuse of one side being practi' caly .acontinuation-of the use of the other s1 e'-. v

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. The combination of a revoluble disk provided upon both of its faces with a magnetic record, magnets mounted upon op 0- site sides of said disk and energized there y, one of said magnets being adapted to be energized whenmoving toward the center. of' said disk, and the other of said magnets being adapted to be energized when moving away from the center of said disk,- and means 7 for moving said magnets toward and from the center of said disks. I

2 The combination of aflrevolubledisk provided upon both of its facesowith amagnetic record, magnets mounted upon op(p0. site sides of said disk and oppositely posed in proximity to said faces, a carriage upon wh ch said magnets are mounted, screw mechanism for propelling said carriage in one direction, other screw mechanism for propelling 'said carriage in'the opposite direction, and means for shifting the control of said carriage from one of said screw mechanisms to the other of said screw mechanisms for the urpose of reversing the direction of travelo said'carriage.

3. The combination of a revoluble disk provided with a magnetic record disposed upon -0 posite sides thereof, magnets 'disposed a jacent to saiddisk and coacting with the magnetic record thereof,- a carriage for supporting said magnets, screw mechanism v for propelling said carriage in one direction, screw mechanism for propelling said carriage in the opposite direction, and a manually-operated member for enabling said carriage to be moved independently of either of said screw mechanisms.

4. The combination of a revoluble disk having two faces and provided upon each of these faces with a record-surface, separate ma netlc members coactlng respectively wit said faces for controlling an electric circuit, switch mechanism for ener izing first one andthen the other of the sai magnetic mechanisms, and means for causin said magnetic mechanisms to. travel first 1n one relatively to the center of the sai disk, separat'In-agnetic members actuated by saldcarriage and disposed upon op osite S'ldGS'Of the sai disk, and means .comp eting an electric circuit through both of said magnetic mechanismsa In testimony whereof I have signed my 5, .name to this specification in the presence of two subscribing witnesses. v
