Pocket Phonograph.
I, Mrs. MARIE FRIED, by former marriage Mrs. Liebermann, a Subject of the
Austrian Emperor, being wife to the merchant Fried, and at present residing
at 7A, Goldschmied-Gasse, in the City of Vienna, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
5 ticularly described and ascertained in and by the following statement:-
This invention has reference to a device which while it can be used like a
phonograph to reproduce any number of spoken words as many times as may
be desired, can be carried about in the pocket; the motor used to rechange the
imprint made upon a sensitive plate by the voice of a speaker, into spoken
words being of so simple construction that no adjustment of the gearing down
to a nicety becomes necessary and that repairs could be easily effected.
My invention is illustrated in the accompanying drawing in a preferred form
of construction, the drawing representing a side view of the apparatus embodying
my invention:
In the drawing a is a push button attached to the extremity of the rod and
being spring actuated. The other extremity of the said rod is beveled off as
shown at c in the drawing. Upon part of its length the rod is provided with
a short rack bar & gearing with a pinion e.
pinion e is mounted the fly wheel f of lead or other suitable material and also
Upon the same shaft with the said
the pinion g which is arranged so as to engage with the toothed edge of the
disc h; the surface of. the said disc being covered with the characters or
rather imprints produced by the voice of a speaker upon a sensitive material
mounted upon the said disc or plate h. These imprints are very much in the
manner of the phonograms used in connection with the ordinary phonograph
and are preferably arranged in a circle about the shaft i of the circular disc or
plate h. The phonographic plate attached to the surface of the said plate h
may be manufactured of metal after a pattern of wax bearing the original
imprints. The whole disc or plate with its axis i may be lifted or lowered
to a certain extent their movement being limited by suitable stops or other
suitable appliances.
By touching the button a the rod 6 will be moved towards the left against the
ension of the spring m mounted upon the rod between the knob or button a
nd the stop t. The shaft i of the disc will then be made to glide upon the
eveled end of the rod b being lifted thereby. At the same time rack d
ngages with pinione which will also cause pinion g to be turned which imparts
ts movement to the phonogram disc h. As soon as the speed of the said disc h
as reached a certain value, the disc will be forced by centrifugal action against
he pin attached to the bottom of the sounding drum 7, in any suitable manner.
he pink may for instance be inserted in a hole of the bottom of the sounding
um and fastener by a screw or nut at the inside of the bottom. The circular
prints upon the phonogram surface of the plate or disc h moving under the
nk will raise and lower the said pin and will cause corresponding oscillations
the flexible diaphragm extended over the bottom of the bollow1.

natural principles will reproduce the sounds which correspond to the circularly
arranged impressions upon the phonogram surface. In consequence of the centri-
fugal force of the fly f, the circular disc is turned several times about its axis
after the rack has passed the pinion e and has moved beyond it, the pin k still
continuing to move over the impressions upon the disc or plate h.
When the button a is released it will cause the rod b to move to the right
again which results in the shaft i gliding off the beveled surface e and arresting
the apparatus.
My invention is capable of various modifications in the form and construc-
tion of the various parts without departing from the essential features of the
invention as pointed out in the claim. The flexible diaphragm forming the
bottom of the drum may be preferably be made of card-board and the point
of the pink may have a diamond of any other material may be used which will
be safe against abrasure.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
In a pocket speaking apparatus, the combination of a rotatable plate bearing
phonogram impressions, with a pin attached to a flexible diaphragm forming
the bottom of a sounding drum or sounding tube, the said rotatable plate being
lifted by the beveled end of a spring actuated rod, a rack bar attached to the said
rod and gearing in connection with said rack bar and with a fly wheel, the said
gearing imparting a rotating movement to the rotatable plate bearing the
phonogram impressions, substantially as described.
Dated this 5th day of December 1899.
