SPECIFICATION forming part of Letters Patent No. 773,304, dated October 25, 1904.
Application filed June 19, 1900.
To all 1071 0711 it may concern:
Be it known that I, PAUL E. VAN VALKEN- BURGH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Phonographs, of which the following is a specification.
This invention relates to improvements in phonographs, and has for its primary object the production of a cheap, simple, and durable instrument that may be operated either by hand or by power.
A further object is to have the recorder and reproducer held in contact with the wax cylinder yieldingly by elastic force as contradistinguished from the force of gravity commonly employed in instruments of this class.
Another object of my invention is to so pivotall y mount the feed-arm and the reproducer or recorder that the weight of the horn or other suitable weight aside from the feed-arm or the diaphragm-box may be utilized to hold the feed-arm in operative contact with the feed-shaft and to hold the reproducer or recorder in operative contact with the record or record-blank.
These and such other objects as may hereinafter appear are attained by the devices vice.
illustrated in the accompanying drawings, in which Figure 1 represents a plan view of a phonograph embodying my invention in its preferred form. Fig. 2 represents an end elevation thereof. Fig. 3 represents a plan view of a modified form of phonograph embodying my invention. Fig. 4c is a transverse section on the line 4: 4 of Fig. 3. Fig. 5 is a detail view of the feed-screw and its contacting de- Fig. 6 is a detail sectional view of the combined recorder and reproducer, and Fig. 7 is an enlarged detail View more clearly showing the preferred manner of constructing the recorder and reproducer.
Similar letters of reference indicate the same parts in the several figures of the drawings.
Referring by letter to the accompanying drawings, A indicates the supporting-frame Serial No. 20,798. (No model.)
of the machine, which may be of any suitable shape and construction, but preferably has the form of a rectangular frame with the central portion of one of the end bars cut away so as to leave the frame open at that end. Upon the opposite end bar of the frame is journaled one end of a shaft B, which projects therefrom toward the opposite open end of the frame, substantially midway between the same, and has rigidly mounted thereon a cylinder G, preferably of wood, which tapers slightly from the end thereof adjacent to the supported end of the shaft and is of a diameter to receive the usual wax-composition cylinder D, which is slipped thereon and held by frictional contact in the usual way of machines of this class. This wax cylinder is of course plain when it is desired to record sounds thereon, or it may be in the shape of what is technically called a record with the sounds already recorded thereon. With a plain cylinder the recorder is of course used, while with the record the reproducer is used.
J ournaled in suitable bearings at one side of the frame A and parallel with the shaft B is a screw -threaded feed shaft E, having mounted thereon a pulley in line with another pulley G, rigidly mounted upon the main shaft 13, said pulleys being connected by a belt of any suitable kind, preferably a small metallic coiled spring H, trained about the two pulleys, so as to communicate power from one to the other. Upon the shaft B and working in the slot cut out of the end bar of the frame is a fly-wheel I for inducing regular motion of the shaft B, to which power is preferably communicated by a crank J, although of course the shaft B may be driven by power in the shape of the usual cheap clockwork mechanism, geared thereto in the ordinary manner. As, however, my primary object is to produce the eheapest possible machine that shall give satisfactory work, I prefer to use the crank, as shown.
Beyond the feed-screw E and extending parallel therewith is a rod K, supported in suitable bearings at the side edge of the frame A, upon which are slidingly mounted dependfir 773,304.

It will also been effected by a single knife-edge fitting 5 be noted that the weight of the horn P is alone into the thread on the feed-shaft; but I prerelied upon to hold. the feed-arm N in proper fer to have a two-point engagement between contact with the feed-screw, and obviously the feed-arm and the feed-shaft by providing whenever it is desired to shift the reproducer two parallel adjacent knife-edges upon the back and forth to different positions upon the end of the feed-arm.

This box serves the purpose of an amplifying chamber, from which the sound produced by the vibration of the side which acts as a diaphragm andto which the tracing-point is secured passes out through the tube Q and horn P in a practically straight line, thus producing very loud and Very distinct reproductions of the sounds that produce the record. The reproducer is of course very light and very cheap, and but for the pressure produced thereon as a result of the slight flexure of the tube Q would not be satisfactory for the intended purpose. struction of the reproducer is such that I am enabled to utilize the same device as a recorder by simply cementing or gluing to the opposite side of the box from that on which the reproducing-point is mounted a suitable support for a recording-stylus W, this support being preferably a small metallic clip having an angularly-disposed tube to receive the stylus.
A phonograph made in accordance with my invention is exceedingly cheap, simple, and durable, and yet is quite satisfactory for a machine of the cheaper class, where especial accuracy cannot be expected.
Obviously numerous changes may be made in the construction and disposition of the parts without departing from the spirit of my invention-such, for instance, as substituting other material for the pasteboard boxes, which are the preferred construction of my reproducer and recorder, for so far as relates to the broad idea of my invention any material that enables the construction of a fiat box having opposing sides to which the recorder or reproducer, or both, can be attached would fall within my invention and are comtemplated by the claims.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1s
