A T T0305 7S r nr ARTHUR H. RYDER, OF NEV'T YORK, NNY?"- SOUND-REGULATOR FOR PHONGRAPHS.

Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed September l. 1905. Seria] No. 276,740.

To all whom t may concern:

Be it known that I, ARTHUR H. RYDER, a citizen of the United States, residing in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Sound-Regulators for Phonographs and other Talking-Aflachines, of which the following is a specification, such as will lenable those skilled in the art to which my invention relates to make and use the same.

The object of this invention is to provide improved means for connecting the horn of a talking-machine or other machine of the class specified to the machine proper, whereby the metallic vibrations or rasping metallic sounds usually produced by machines of this class are in a measure done' away with and a more regular and musical tone or voice-tone produced, a further object being to provide an improvement of the class specified for use in connection withthe delivery-horns of talking-machines and similar instruments, whereby the sound-waves are prevented from travcling around the horn inspiral curves and whereby/theharsh grating or similar metallic soundsare to a considerable extent obviated `and whereby the operator may at will regulate the volume of'sound produced by the horn, a still further object being to provide a horn-coupling `for instruments of the class specied containing a supplemental vibratory device; and with these and other objects in view the invention consists in an attachment for instruments of the class specified constructed as hereinafter described andY claimed.

The invention i= fully disclosed in the following speciicatii u, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters' in each of the views, and in which- Figure l is a side view of my improved horn attachment for instruments of the class specified and showing the method of connecting it with the machine and with the horn; Fig. 2, a sectional view ofthe attachmenton the line 2 2 of Fig. l; Fig. 3, a view similar to Fig. 2, but showing the attachment proper on an enlarged scale 3 Fig. 4, asection on the line 4 4 of Fig. 3; Fig. 5, an end view of a supplemental vibratory device which l employ; Fig. 6, a reversed side view of the vibratory device shown in Fig. 5 3 Fig. 7, a section on the line 7 7 of Fig. 1 and on the line 7 7 of Fig. 3 and also a similar section through Fig. 2 Fig. 8, a side view of a valve -plate which I employ, and Fig. 9 a transverse section thereof.

In the drawings forming part of this specification l have shown at c the reproducer of a talking-machine or other sound or musical reproducing machine and at a2 the deliveryhorn thereof.l The reproducer a is provided with the usual tube a3, with which in practice my improved horn-attaching device b is connected. The horn-attaching device b in the form of construction shown comprises a tube made of two parts b2 and b3, and the part b3 in the form of construction shown is provided with an enlarged inner end member b4, into which the part b2 is screwed, and mounted on the enlarged end member b4 of the part b3 is a collar or band c, said collar or band being rotatable and being placed between annular beads b5 and b, formed, respectively, on the g tube members b3 and b2.

The enlarged part b4 of the tube member b3 is provided approximately centrally thereof with a transverse partition d, having oblong ports or passages d2 arranged concentrically Iof the center thereof, and placed on the inner face xof said partition is a rotatable valveplate c, provided with a central stud e2, which passes outwardly through the partition d and through a central hub d? formed thereon, and the head of which is enlarged, as shown at e3, to prevent its movement longitudinally of the attachment, and said valveplate is provided with a fiange or rimfc4, and passing through the collar or band c and through the transverse oblong slot c2 in the end member b4 of the tube member b3 is a screw f, which passes into and is secured in the flange or rim e4 ofthe valve-plate e, and by means of which said valve-plate may be turned, and the said valve-plate is provided with concentrically -arranged oblong slots forming ports or openings c5, which are adapted to register with the corresponding ports or openings d2 in the partition d.

Secured to the collar or band c by the screw f is a pointer g, which ranges longitudinally of the tube member b2 and is adapted to operate inconnection with a transverse scale g2, formed on said tube member, and removably placed in the tube member b2 is a supplemental vibratory device comprising a collar h, said collar being provided at its outer end with inwardly-directed proj ecticns h2. Within the collar h of the supplemental ICO IIO

i volume of vibratory sound passing through ma. l '45- vibratory device is placed a rigid disk i, preferably composed of fiber and provided with small ports or passages i?, which in the form of construction shown are arranged concen- 5 trically around the center thereof, and placed on the side of the diski adjacent to the valveplate e is a iiexible diaphragm j, also referably composed of fiber and separate from the disk c by an annular band or gasket jz, xo and the diaphragm j is held in the dia hragmcollar h by an open spring-ring lc, etween which and said diaphragm 1s placed an annular gasket 752.

As thus constructed it will be seen that the the partition d may be regulated at all times by turning the valve-plate e, which is done by turning the collar or band c, and the pointer g operating in connection with the 2o scale gv2 will tell to what extent the ports or passages d2 in the partition d are opened and -closed.

In the operation of this device the soundwaves from the re roducer a iirst impinge on 2 5 the perforated dis i of the vibratory device Within the tubular member b2, which, being constructed of non-metallic substance, insulates all grating, harsh, or indistinct sounds foreign to the record, and the said sound- 3o waves pass through said disk and strike against the sensitive diaphragm j, which sets up a new series of sound-Waves which are deprived of their tendency toward a spiral movement and which may be regulated in 3 5 volumes at the will of the operator by turning the collar or band c. The result of this is to produce a more perfect tone, voice, or musical sound which is to an extent free from the metallic and harsh qualities usually pro- 4o duced by instruments of this class.

As thus constructed it will be seen that my improvement involves a regulator placed between the delivery-horn and the reproducer and comprising in its construction a vi- 4 5 bratory diaphragm, a stationary sound-reguf lating diaphragm, and a supplemental-volume or sound-volume regulating device involving a rotatable member located in the axis of the .sound-Waves passing through the reproducer, and while I refer the construction shown and describe( it will be apparent that changes therein and modifications thereof may be made Without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The herein-described means for connecting the horn ofA a reproducing instrument with said instrument, comprising a tubular coupling having a fixed transverselyarranged apertured plate therein and an apertured valve-plate cooperating with said fixed plate, and-external devices movable independently of the coupling whereby said valve-plate may be rotated and the extent of said rotation indicated, said coupling being also provided in the end thereof adjacent to the instrument with a supplemental vibratory device.

2. The herein-,described means for connecting the horn of a reproducing instrumen with said instrument, comprising a tubulaiy coilpling having a iixed transverselyarra ged apertured plate therein and an apertured valve-plate cooperating with said fixed plate, and external devices movable inde er dently of the coupling whereby said va ve plate may be rotated and the extent of said otation indicated, said coupling being also r rovided in the end thereof adjacent to the instrument with a supplemental vibratory device, consisting of'a transversely-arranged perforated disk and a vibratory diaphragm adjacent thereto.
