Improvements in Apparatus for Reproducing Sound Records.
1, GIANNI BETTINI, of 110, Fifth Avenue, in the City and State 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 ascer-
tained in and by the following statement:-
-
The present invention relates to machines for reproducing the sound waves
recorded upon a suitable surface and making a duplication of such sound waves
upon a second surface.
In the drawings I have shown a construction embodying the features of the
present invention, in which drawings Fig. 1 is a plan view, certain parts being
broken away.
Fig. 2 is an end elevation view,
Fig. 3 is a section along line 3, 3 of Fig. 1.
Fig. 4, is a detail view in plan of parts shown in Figs. 2 and 3.
Fig. 5 is a side, elevation of the parts immediately connected with the record-
tracing and cutting devices.
Fig. 6 is a plan view of the parts shown in Fig. 5 and
Fig. 7 is a detail view in section along line 7, 7 of Fig. 6.
Like letters of reference refer to like parts throughout the several views of the
drawings.
Referring to these drawings in detail 1 designates a suitable support upon
which rests the frame 2 of the machine which is secured to said support by a
clamp 3 extending from a plate 4. Bosses 5 project upwardly from this plate and
a shaft 6, supporting the frame 7 which carries the master record cylinder is
journaled therein. Also projecting from said plate 4 are webs 8 to which is
pivotally secured a plate 9, whose under surface rests against a cam 10. An
adjusting screw 11 passes through the frame 7 and impinges against the upper
surface of the plate 9. This adjusting screw 11 is for the purpose of positioning
the master record cylinder 12 relatively to the record-following stylus. The record
eylinder is moved bodily into and out of operating position by means of the
cam 10, which is secured to a shaft 13 journaled in uprights 14 projecting from
the plate 4, the shaft 13 having secured to it an operating handle 15.
This
The master cylinder 12 is supported on a shaft 16 which shaft is journaled at
approximately its middle portion in an arm 17 projecting from the frame 7 and
is journaled at one end by a conical journal point projecting from an arm 18
and at the opposite end by a similar journal point upon a pivoted arm 19.
arm 19 is operated so as to be moved away from its position supporting the end
of shaft 16, by means of a sleeve 20 which is provided with a crank arm 21 con-
nected to a link 22, which is pivoted to the arm 19, said link 22 being provided
with an arc shape portion 23. The sleeve 20 is provided with an interior square
shaped opening and is operated by the handle 24 having a square end fitting into
the opening in the sleeve 20. By these means the arm 19 is moved away from
its position opposite the end of the master record cylinder 12, so that the master
record cylinder may be taken off of its support and a new record cylinder placed

page_text: in position. The cylinder upon which the sound record of the master cylinde
is to be reproduced is here designated by the numeral 25 and is supported in
position below and to one side of the master cylinder upon a shaft 26, one end o
which is provided with a driving pulley 27 and a gear wheel 28 meshing with
gear wheel 29 which in turn meshes with gear wheel 30 on shaft 16, which carrie
the master record cylinder. The gear wheels 28, 29 and 30 are connected togethe
by links 31 so as to be always in mesh throughout all variations in position
relatively to each other of the master record cylinder and the cylinder upon whic
the record is to be reproduced. The shaft 26 is provided with a threaded portion 32
upon which bears a half round threaded yoke, secured to arm 33, whose other
end is connected to a sleeve 34 on shaft 35. The sleeve 34 carries the record
tracing and reproducing parts and is moved longitudinally of the cylinders a
a rate bearing a definite relation to the rate of rotation of the master cylinder
and the cylinder upon which the sound record of the master cylinder is to be
reproduced.
Clamped upon the sleeve 34 is an arm 36 which extends underneath the cylinder
which is to receive the duplication of the sound record, the end of said arm
normally resting upon the rail 37. Formed integrally with said arm 36 is a
housing 38 which is adapted to receive a post 39 upon which are pivotally mounted
the record duplicating parts. The post 39 may be secured in any desired position
by means of the set screws 40. At its upper portion the post 39 branches into
forks 41 between which is journaled a channel piece 42 provided with a slot 43.
Projecting rearwardly from the channel piece 42 is a threaded rod 44 upon which
is screwed a counterweight 45, said counterweight being designed to counter-
balance the weight of the reproducing stylus and appurtenant parts. An arm 46
is adapted to fit in the channel piece 42, being secured therein so as to have longi-
tudinal adjustment by means of a set screw 47 passing through the slot 43 in
the channel piece. The armi 46 is bifurcated at its outer end into arms 48.
Journaled between these arms 48 is the stylus carrying arm 49 which is provided
with a stylus 50. A spring 51 is secured at one end to the arm 49,
and the other end is secured to a cord 52 fastened to a thumb screw 53 on a
post 54, the turning of the thumb screw 53 adjusting the tension of
the spring by winding or unwinding the cord 52 upon each side of the stylus
carrying arm 49 bears a leaf spring 55 operating to maintain the stylus carrying
arm 49 in alignment with the line running longitudinally through the centre of
the arm 46. Stretched between the arms 48 is a wire 56 which passes through an
eye 57 formed in the stylus 50 and maintains the arm 49 in a plane substantially
parallel with the plane of the arm 46. Pivoted on a cross piece 58 extending
transversely between the arms 48 is a supporting piece 59 for the record cutting
stylus 60, which is pivoted on a projection 61 on the supporting piece 59. The
record cutting stylus is secured to the tracing stylus 50 by any desired means,
as by a wire 62 passing through the aperture 63. The outer end of the supporting
piece 59 is provided with a weight 64 and the opposite end with a tail piece 65
whose limit of movement is defined by a set screw 66. For the purpose of limit-
ing the oscillation of the channel piece 42 upon which are supported the stylus
carrying parts I provide a set screw 67 passing through a threaded hole in a
lug 68 projecting from the post, 39.
An arm 69 carries a cone bearing adapted to engage the shaft 26, and is hinged
so as to be capable of movement into and out of supporting position for the pur-
pose of removing the cylinder 25 and is locked in its closed position by means of
a catch 70.
When a master cylinder has been copied and its record transferred to the
cylinder 25, the operating handle 15 is pressed down, thus turning the cam 10
and raising the master record out of contact with the record-tracing stylus 50.
The cutting stylus is then raised from contact with the cylinder 25 by tilting
the arm 36 by means of the rod 71 lifting the same, the rod 71 extending under
the end of the arm 36 throughout the length of its path of movement longitudinally

page_text: of the phonograph cylinders. The rod 71 together with the rod 72 which are con-
nected by end pieces 73 are secured to the plate 9 and are moved with said plate
when it is tilted by a cam 10. A limiting stop 74 is secured on the rod 71 and is
adapted to be secured in any desired position by means of a set screw 75.
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:-
