id Reproducing Apparatus.
We, WILLIAM GEORGE SPIEGEL, of 19 East 3rd Street, Electrician, and LEROY
WILBUR BALDWIN, of 60 Murray Street, Gentleman, both of New York, United
States of America, do hereby declare the nature of this invention to be as
follows:-
This invention consists of certain improvements in sound reproducing apparatus
and the object thereof is to so cheapen and simplify the construction of such
apparatus that machines can be sold and used as toys. The invention will be
employed to reproduce, from a record made in the usual way by more costly record-
ing apparatus, the series of sounds whose record has been imprinted on said
customary and well known form of sound record.
The preferred form of the apparatus is illustrated in the accompanying three
sheets of drawings, in which
Fig. 1 is a side elevation of an apparatus embodying the invention.
Fig. 2 is a plan view of the same.
Figs. 3, 4 and 5 are detail views of modifications.
Fig. 6 is a vertical cross section taken through the portion of the apparatus
called the governor, illustrating the construction of said governor in detail.
Figs. 7 and 8 are details showing a modified form of ring for said governor.
Throughout the drawing like reference figures refer to like parts. 1 repre-
sents the main frame of the machine, which may be placed upon a table, shelf or
similar support. 2 is a standard on said main frame which supports the clock-
work 3. This clockwork is driven by the spring 4, which is wound up by the
key 29, and on the shaft 5, of the clock work is mounted a grooved pulley 6. A
belt or endless cord 7, conveys motion from the pulley 6, to the pulley 8, which
is mounted on the shaft 9, which is journalled in the standard 12. On the
pulley 10 is mounted a cylindrical sound record 11, of the well known type.
13 is still another standard, which is preferably made of wood well dried and
seasoned and this supports a sounding board which may be of any desired construc-
tion, but which is preferably composed of the wooden cross-piece 14, the
intermediate strip of rubber or gutta percha 15, and the top strip of wood 16,
which is held in contact with the strip of gutta percha by the upwardly projecting
ears of the strip 14, or by some equivalent fastening. 17 is a peg of wood or
other material projecting upward from the centre of the strip 16.
18 is a long tubular piece of glass or stylus tube having the end portion 19,
ent at right angles to its principal portion. On the other end of the tube of
glass is blown a point or stylus 20, which is adapted to fit into the groove on the
evolving record 11.
Near the other end of the glass tube or stylus is cast or blown a lug 21. A

page_text: spring or elastic band 22 has one end connected to this lug, while the other end
is connected to an adjusting screw 22" or other adjusting apparatus mounted on
the main frame and preferably arranged under or approximately under the
sounding board 16.
In the standard 13, is formed a cylindrical or conical hole 27, in which may be
introduced a rubber tube or cone 28.
In the modification illustrated in Fig. 3, the peg 17, is replaced by a
socket 25, on the sounding board 16, and into which the end 19, of the glass tube
is introduced and in which it rests loosely.
In the modification illustrated in Figs. 4 and 5 the peg 17 is replaced by a
triangular lug or cleat 24, in which the end of the glass tube may rest without
having any bent portion 19, and in this case the lug 21 is projected or extended
for some distance below the glass tube 18, the object being to give sufficient
leverage to keep the tube from rolling over in the point 20, the tension of the
spring 22, on the end of the long lug 21, serving to produce this effect.
In the modification illustrated in Figs. 4 and 5, the point of attachment of
is
the spring 22, should be more nearly under the sounding board 16 than
necessary in the other form, so that the end of the glass tube 18, is pressed into
the opening in the lug or cleat 24.
The governing apparatus consists of an extension of the rapidly rotating shaft 5,
its outer end being supported on the centering screw 25, which is mounted in the
upright 27. On the shaft 5, is keyed or otherwise fastened the collar 28, which
has ears to which are pivoted the ends of the fan blades 29, 29. The ring 26,
encloses or surrounds said fan blades and being mounted on the sliding standard 30,
is capable of adjustment in the line of the shaft 5, by means of the adjusting
screw 31, which is housed in the stationary nut 32.
In the modification illustrated in Figures 7 and 8, the slotted ring 33,
immediately encompasses the fan blades 29, 29, and is capable of sliding longi-
tudinally along the same, though by virtue of its slots into which the fan blades
fit, the ring rotates with the fan. The ring 33, is mounted and rotates in the
upright non-rotating ring 26.
The method of operation of the invention is as follows: The clockwork spring 4,
being wound up, the clockwork begins to run down rotating the record 11, and
causing the stylus and stylus tube 18, to vibrate according to the irregularities in
the groove cut on said record. These vibrations are amplified by the sounding
board 16, and modified to the requisite degree by the strip of gutta percha or
equivalent material 15, and are transmitted through the standard 13 to the
air enclosed in the tube or cone 28, which has been inserted in the opening 27.
In order to obtain an even and regular speed of rotation of the record 11, the
governor illustrated in the detail in Fig. 6, or the modifications shown in Figs. 7
and 8 is particularly well adapted. The adjustment of the slide 30, controls. the
angle at which the fans 29, 29 are inclined to the shafts and consequently their
angular velocity which decreases as their inclination to the axis and consequent
radius of rotation increases. The further the ring carried by the slide is forced
to the right (see Figs. 6 and 8) the farther out the fan blades may spread and
the greater the resistance they will encounter from the air and consequently the
more they will retard the mechanism. In this way the machine may be adjusted
to run at nicely graded speeds and its movements for any one adjustment will
be uniform and regular.
Of course various changes would be made in the details of my construction
and in the materials employed without departing from the principle of the
invention.

We, WILLIAM GEORGE SPIEGEL, of 19 East 3rd Street, Electrician, and LEROY
WILBUR BALDWIN, of 60 Murray Street, Gentleman, both of New York, United
States of America, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:--
This invention consists of certain improvements in sound reproducing apparatus
and the object thereof is to so cheapen and simplify the construction of such
apparatus that machines can be sold and used as toys. The invention will be
employed to reproduce, from a record made in the usual way by more costly record-

customary and well known form of sound record.
The preferred form of the apparatus is illustrated in the three sheets of drawings
filed with our Provisional Specification in which :
Fig. 1 is a side elevation of an apparatus embodying the invention.
Fig. 2 is a plan view of the same.
Figs. 3, 4 and 5 are detail views of modifications.
Fig. 6 is a vertical cross section taken through the portion of the apparatus
called the governor, illustrating the construction of said governor in detail.
Figs. 7 and 8 are details showing a modified form of ring for said governor.
Throughout the drawing like reference figures refer to like parts.
On the
1 represents the main frame of the machine, which may be placed upon a table, shelf
or similar support. 2 is a standard on said main frame which supports the clock-
work 3. This clockwork is driven by the spring 4, which is wound up by the
key 29, and on the shaft 5, of the clockwork is mounted a grooved pulley 6. A
belt or endless cord 7, conveys motion from the pulley 6, to the pulley 8, which
is mounted on the shaft 9, which is journalked in the standard 12.
pulley 10 is mounted a cylindrical sound record 11, of the well known type.
13 is still another standard, which is preferably made of wood well dried and
seasoned and this supports a sounding board which may be of any desired construc-
tion, but which is preferably composed of the wooden cross-piece 14, the
intermediate strip of rubber or gutta percha 15, and the top strip of wood 16,
which is held in contact with the strip of gutta percha by the upwardly projecting
ears of the strip 14, or by some equivalent fastening. 17 is a peg of wood or
other material projecting upward from the centre of the strip 16.
18 is a long tubular piece of glass or stylus tube having the end portion 19,
bent at right angles to its principal portion. On the other end of the tube of
glass is blown a point or stylus 20, which is adapted to fit into the groove on the
revolving record 11.
Near the other end of the glass tube or stylus is cast or blown a lug 21.. A
spring or elastic band 22 has one end connected to this lug, while the other end
is connected to an adjusting screw 22" or other adjusting apparatus mounted on
the main frame and preferably arranged under or approximately under the
sounding board 16.
In the standard 13 is formed a cylindrical or conical hole 27, in which may be
introduced a rubber tube or cone 28.
In the modifications illustrated in Fig. 3, the peg 17, is replaced by a socket 25,
on the sounding board 16, and into which the end 19 of the glass tube is
introduced and in which it rests closely.
In the modification illustrated in Figs. 4 and 5 the peg. 17 is replaced by a
triangular lug or cleat 24; in which the end of the glass tube may rest without
having any bent portion 19, and in this case the lug 21 is projected. or extended

page_text: for some distance below the glass tube 18, the object being to give sufficient
leverage to keep the tube from rolling over in the point 20, the tension of the
spring 22, on the end of the long lug 21, serving to produce this effect.
In the modification illustrated in Figs. 4 and 5, the point of attachment of
the spring 22, should be more nearly under the sounding board 16 than is
necessary in the other form, so that the end of the glass tube 18, is pressed into
the opening in the lug or cleat 24.
The governing apparatus consists of an extension of the rapidly rotating shaft 5,
its outer end being supported on the centering screw 25, which is mounted in the
upright 27. On the shaft 5, is keyed or otherwise fastened the collar 28, which
has ears to which are pivoted the ends of the fan blades 29, 29. The ring 26,
encloses or surrounds said fan blades and being mounted on the sliding standard 30,
is capable of adjustment in the line of the shaft 5, by means of the adjusting
screw 31, which is housed in the stationary nut 32.
In the modification illustrated in Figs. 7 and 8, the slotted ring 33,
immediately encompasses the fan blades 29-29, and is capable of sliding longi-
tudinally along the same, though by virtue of its slots into which the fan blades
fit, the ring rotates with the fan. The ring 33, is mounted and rotates in the
upright non-rotating ring 20.
to
The method of operation of the invention is as follows:-
The clock work spring 4, being wound up, the clockwork begins
run down rotating the record 11, and causing the stylus and
stylus tube 18, to vibrate according to the irregularities in the
groove cut on said record. These vibrations are amplified by the sounding
Board 16, and modified to the requisite degree by the strip of gutta percha or
equivalent material 15, and are transmitted through the standard 1, to the
air enclosed in the tube or cone 28, which has been inserted in the opening 27.
In order to obtain an even and regular speed of rotation of the record 11, the
governor illustrated in the detail in Fig. 6, or the modifications shown in Figs. 7
and 8 is particularly well adapted. The adjustment of the slide 30, controls the
angle at which the fans 29-29 are inclined to the shaft and consequently their
angular velocity which decreases as their inclination to the axis and consequent
radius of rotation increases. The further the ring carried by the slide is forced
to the right (see Figs. 6 and 8) the farther out the fan blades may spread and
the greater the resistance they will encounter from the air and consequently the
more they will retard the mechanism. In this way the machine may be adjusted
to run at nicely graded speeds and its movements for any one adjustment will
be uniform and regular.
Of course various changes could be made in the details of construction and in
the materials employed without departing from the principle of the invention.
