To all whom it may'concern:

Be it known that I, HANS STAROKE, a citizen of the German Empire, residing at Elberfeld, Germany, have invented certain new and useful Apparatus for Use'in Recording Telephonic Messages or Sounds, of which the following is a specification.

- In apparatus hitherto known for recording telephonic messages or sounds on a phonegraph-cylinder without anp assistance of the s eaker the recordingwas imited to a single rum, so that onl a limited amount of conversation could e recorded in this 'way. This drawback is obviated by the resent invention by a series of phone up -cylinders being successively brought into the desired recording position by an automatic apparatus, hereinafter described, the beginand the end of the throwing into gear of e cylinders being notified to the users by the ringing of a bell in roximity to the mouthpiece or diaphragm o the receiver so that the conversation may be recorded with- V out anygaps. 3s

A construction ofthe apparatus according to this invention is illustrated, bg rway ofxs ample, in the accompanying swings, in which Figure 1 is a longitudinal section through a switching apparatus according to this Invention. tion on the line A A seen in thedire'ction of the arrow. Fig. 4 shows the connectiondiagram Fig. 5 thearra ement'of cha e-' wheels. Fi .6 shows the r atchet-g-ear cit 's anism for stopping the changing ofthe cy1in ders; and Figs. 7 and 8" are top ian views of Figs. 7 and 8, traites the signaling the change.

he arrangement and the working of the ap aratus are as follows: 7 r

en the a paratus is to be used, eiectro magnets c an d are connected to'the telegpsone-Iine b by means of switches a. The t electromagnet operatesin the veil-known manner the needle e, recording the conversation on the cylinder, the second magnet attracting, when current asses through it,

alover-armature g, PI'OVIdBd with ratchet-- teeth and piyoted atf Fig. 6, thus releasing a pawl 11, secured to t e carriage it. When the circuit is broken, the ratchetteeth under the influence of a s ring 7c come again into thp path of the paw 'i, so that if the carriage moves in the direction ofthe arrow c, Fig. 2-

2 is a P g 3, a cross-m igs. 7 and 8 illustrate the mechectively; ig; 9* iiinss of the current. The movement of the carriage is eflected by means to be hereinafter described:

A toothed'wheel m, Fig. 1, mounted on a spindle Z, is rotated by a clockwork (not s own in the drawings) and transmits its rotation in "the osition shown in Fig. 1 by rneansof whee s n, and o to a screw-spindle 3), serving to drive the carriage h that is,'to advancethe carriage in the direction of the arrow c. When the carriage h nears the end of its trevei, the proj eetion q upon it strikes a for-kt, pi ed etc, which, by means of a fixed iectionu causes the spindle Z to "will be seen from the directions shown by ar. 5, the spindle p wiii be caused to rows in Fi rotat'in t e o'p osite direction, effect return 0 the carriage in the direction 'oithe arrow 1. At the end of the return movement a perfectly similar device g s t a miigagaineh'an e the direction of rotation of municated b the wheel m to the spindle Z is "liheispindlep. The rotary movement comtransmitted y toothed wheels 1 and 2 to a y spifidie 3, carrying the phoncigaph-cylinder,

"winch is caused to rotate. t e cylinder: supporting frame 4 5 is supported by the carriage h, to c move longitu the transmission wheel 1. wheel 1 is mounted on thespindlel by means of ajeather-key sliding in the groove 6, the shifting during the advance being efieeted by a 8 ring .7,s'ecured to the carria e h, :whiie Whoa I. During that change the part u linders not only rotate, but] ally also at the same time,"

v hichnioveinents nust also be foigosegity To that end the .roo durlngtire return the driving is e ected by a strikes the toothed wheel 1 and by overcoming stee in 7 shifts the latter, thus disengaging'it 'iroin the wheel 2. The shifting of the indie Zreleases also for a moment a disk forming the support for the cylinders and arranged on the cross-wail of the carriage, as will be understood on examining I 55 number of projections Figs. '7 and 8. During the advance of the carriage the art 10, mounted on the spindle l, is

in the pat h of the disk 9, so that the latter is thereby prevented from rotating. On the 5 above-described movement of the spindle l the lockin of the disk is released, so that the --disk can eely move longitudinally and is locked a ain on reaching the part 12. The release of the disk 9 and of the toothed wheel 2 enables the cylinder-sup be turned in the support 5 means of an automatically-windin steel and 13. When the next cylinder as been brought in this way into position, the spindle 3 of the roller 15. is again arrested by the disk 9, as in the meantime the part 12 has come into the path of the said disk, and thus revents it from rotating further. During t e return of the carriage h the toothed wheel 1 after the removal of the part it and under the action of the spring 7 is immediately caused to en age with the wheel 2, mounted on the spind e of the cylinder. B means of a pawl-gear 21, mounted on the ame and clearly shown in 2 5 Fig.2, the steel band 13 is prevented from becoming unwound, so that, the disk 9 forming an abutment .against which the spindle 3 is held, the phonogra h-cylinder is su ported in a sufiiciently ri i manner. On t e shift- 0 ing of the spindle%, which takes lace at the end of the return movement of t e carriage, the disk 9 must remain locked on the portion 11, so that another change of cylinder may not take place. To this end a second ratchetgear 15, pivoted at 14 to the 1011 itudinal wall of the carriage, is provide which ratchet-gear is released dur' the advance of the carriage, as shown in ig. 7. On the movement of the spindle taking place at the 0 end of the advance movement as soon as the part 12 comes into the path of the disk 9 the ratchet-gear 15 is turned, b means of the part 10 and an arm 16, into t e lockin position. (Shown in Fig.8.) On the bac ward shifting of the spindle the release of this lookortihg frame 4 to ingear is effected by the part, 12, which acts on t e pivoted arm 17 assoon as the part 10 has again come into the path of the disk 9.

The beginnin and the end of the change are notified to t e speaker by a bell operated by pins 18 19, mounted on the carriage h,

w ich strike the lever 2001 the bell-hammer,

which is thus oscillated, the lpins striking the tooth-shaped projections oft elever20. The

encountered by the pins 18 or 19 and the number of the strokes of the bell caused thereby can be used for distinguishin the beginning and the end of the change 0 cylinders.

The sounds of the bell, amplified, if desired, by a sound-board, are projected from as near as possible onto the diaphragm of the receiver and thence conveyed through the telephone-line in the well-known manner to the ear of the person at the transmitter.
