SPECIFICATION forming part of Letters Patent No. 631,558, dated August 22, 1899. Application iiled September 14, 1898. Serial No. 690,904. (No model.)

To @ZZ whom it may concern:

Be it known that LJosnr CHANIA, a subject of the King of Roumania, residing in Lemberg, Galicia,Austria-Hungary,have invented certain new and useful Improvements in Phonographs, of which the following is a specification.

The object of this invention is to provide an apparatus whereby sounds of any kind may be recorded through the medium of light-rays which are so controlled relatively to the waves of sound that they are subjected to the iniiuence of the latter and their intensity more or less varied and whereby the recorded matter may be subsequently delivered, also through the medium of light-rays, under whose influence there is an electric circuit controlling a sound-transmitting diaphragm.

In view of the foregoing objects -the first part of the invention consists in an apparatus wherebya record is made of the variations in intensity of light-rays, said variations being eifected by the action of sound-waves, and the second part of the invention consists in an apparatus whereby the recorded matter is delivered through the medium of light-rays and an electrically-controlled sound-transmitting diaphragm under the iniiuence of said light-rays. l

In the accompanying drawings, Figure lis a sectional view of an apparatus embodying the first part of my invention, and Fig. 2 is a similar View of an apparatus embodying the second part of my invention.

In said drawings, referring particularly to Fig. l, d designates a case wherein is arranged a tube b, which penetrates one of the side walls of said easev and which is provided at its outer end with a suitable mouthpiece.

c indicates a reflector which is disposed in alinemeht with the inner end of the tube b, being preferably secured to the opposite wall of the case, and which is of such character that sound-waves thrown against it from the tube b, whereby they are transmitted into the apparatus, will effect sufficiently appreciable vibrations thereof to produce the desired results.

d designates another reflector, which is (if desired, adjustably) secured to a third wall of the case in such a position that a light thrown upon it can be reflected therefrom tothe refiector c. y fdesignates a source of light which is so fdisposed that its rays can be thrown upon the `reiector d and from thence transferred to the reflector o, Where they will be again reflected. llc represents a partition which is arranged in said case ot and which forms a compartment therein distinct from the main portion of said case. The compartment thus formed is situated in line with the rays which are thrown from the reflector c, and the wall adjacent to said reflector is inclined substantially at right angles to the line of said rays and is provided with an orifice wherein is arranged a lens g, through which said rays are adapted to pass and whereby they are focused.

h is a small case wherein is contained a sensitized strip similar to that used for photographic purposes, said strip being passed over an auxiliary roller i and being adapted .to be ultimately wound upon a roller i. It should be remarkedthat the auxiliary roller z' is so disposed relatively to the lens g that the focus of the rays from said lens will be coincident with the sensitized surface of the strip passing over said auxiliary roller. In .order that no light may leak into the compartment wherein is contained the sensitized strip, a conical shield Z is secured to the inclined wall of the partition about the opening formed therein for the lens and projects into 'contiguity to said strip. It will be seen that in the use of the apparatus just described and constituting the firsty part of my invention light-rays will be ultimately transmitted from the source of light f onto the sensitized strip in concentrated condition and that the desired record may be produced on said sensitized strip by sound-waves which maybe thrown onto the reiiector c, in-

tercepting to a more or less extent'the lightrays which coincidentally therewith meet the l reector and effecting vibrator-y action of said reiiector, the result being variations in the action of the light-rays focused onto the sensitized strip.

In the apparatus constituting the second y part of my invention I have provided a case a', comprising, preferably, four compartments,

one of which is in communication, as and for IOO the purposes hereinafter described, with two of the others. In one of said compartments is placed a reflector d', which is situated in opposition to an opening therein that communicates with another compartment. In said opening is situated a lens t', and between said lens and the reflector CZ is suitably arranged a source of light j".

In the compartment between which and the one just described is disposed the lens t' a casing h' is situated, said casing being adapted to receive the sensitized strip upon which the record has been placed by the apparatus constituting the rst part of my invention and which is fed from a roller fr over an auxiliary roller r', the latter being arranged in proximity to the lens 2 and so that the rays of light passing through the latter will be focused by it onto the sensitized strip and in coincidence with the matter thereon recorded.

A conical shield m is arranged about the opening for the lens, said conical shield being provided for the same purpose as the similar device hereinbefore described. Said conical shield may comprise a portion of the partition between the compartment containing the sensitized strip and another compartment not heretofore particularly referred to, said partition having an opening for the reception of a tube fa, and said opening and the tube being so situated that any light redected off of the surface of the sensitized strip may be transmitted through said tube into the compartment adjoining the one in which the sensitized strip is arranged and with which said tube communicates.

a: at designate a'divided arbor, which is journaled in the compartment last particularly referred to and which is rotated by any suitable mechanism, as by clockwork 7a2. Saidarbor carries a sheave 7;, which comprises a pair of disks, between which are disposed concentrically a series of strips or blocks of selen 752, which are supported by insulations s. The sheave just referred to is so disposed relatively to the tube n that light transmitted through said tube will be successively thrown onto the selen strips as the arbor is rotated. It should be further remarked that the disks of the sheave 7c are respectively carried by the divided portions of the arbor.

fu designates an electrical circuit having a source of electrical energy at q and including the divided arbor ce fc and the sheave 7c and an electromagnet e, which is situated in the fourth compartment of the case. Said electromagnet is adapted to control a diaphragm p, which constitutes the armature thereof and which is situated in an opening formed in an outer wall of said compartment.

t denotes a funnel-shaped shell surrounding the opening wherein the diaphragm p is arranged, said shell being provided for an obvious purpose.

In view of the above description of the apparatus constituting the second part of my invention it will be seen that the light thrown from the reflector (Z through the lens 2 and by the latter concentrated on the record will be reflected olf the surface of said sensitized strip and thrown onto the selen strips of therevolvingsheave. The variations in the record will effect variations in the action of the rays on the revolving selen strips,and consequently produce in them a greater or less resistance to the electric current in the circuit of which said strips form a part, according tothe wellknown quality of selen under the action of light. The variations in the electric current will effect the intermittent energization of the electromagnet e, whereupon the diaphragm p will be actuated and sounds produced.

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

1. In a sound-recording apparatus,the combination with a source of light,a movable sensitized body, a vibratory reflector adapted to transmit the rays of light from the source thereof to the sensitized body, and means for projecting sound-waves onto said reflectorat points coincident with the points of impact of the light-rays therewith, substantially as described.

2. In a sound-recordin g apparatus,the combination of a source of light, a movable sensitized body, a vibratory reflector adapted to transmit the rays of light from the source thereof to the sensitized body, a lens disposed between said vibratory reiiector and said sensitized body and adapted to concentrate the rays on the latter, and means for projecting sound-waves onto saidreiiector at points coincident with the points of impact of the lightrays therewith, substantially as described.

3. Inasound-deliveringapparatus,thc combination with a source of light, a suitable body having the record to be delivered on its surface, and an electric circuit including a sounding device and a series of variable rcsistance devices, the light being adapted to be transmitted from its source onto the record and thence to the variable resistance dcvices, substantially as described.

4t. In a sound-delivering apparatus,a source of light, a suitable body having the record to be delivered on its surface, and an electric circuit including a solunding device and a strip or strips of selenjthe light being adapted to be transmitted from its source onto the record and thence to the selen strip or strips, substantially as described.

5. In a sound-delivering apparatus,a sou ree of light, a suitable body having the record to be delivered on its surface, an electric circuit including a sounding device and a series of selen strips, the light being adapted to be transmitted from the record toward said selen strips, and means for moving said selen strips successively across the path of the light, substantially as described.

6. In a sound-deliveringapparatus,a source of light, a suitable body having the record to be delivered on its su rfacc, a reflector for IIO also included in said circuit, and a soundproducing diaphragm controlled by said electromagnet, substantially as described.

In Witness whereof I have hereunto signed 15 my name, this 28th day of July, 1898, in the presence of two subscribing'witnesses.
