52 THE TALKING MACHINE WORLD. Phonograph Machine. Herbert S. Mills, Chicago, 111. Patent No. 929,775. The primary object is to provide a machine wherein provision is made for winding the spring which serves to actuate the record of a phonograph by means of a motor which will operate for a predetermined period of time, when set in motion, thereby to give to the spring serving to actuate ig7 / the record a predetermined tension. In the accompanying drawings this invention is shown embodied in a combined pictureexhibiting and phonograph machine, the phonograph being of a well-known type employing a disc form record. In the drawings Fig. 1 represents a side eletional view of an improved machine, portions of the casing being broken away to expose a part of the ■picture-exhibiting device and portions of the phonograph; Fig. la, a detail of a vibrative counteracting device employed in connection with a stop-actuating lever, which lever may be actuated by a coin or in any other suitable way; Fig. 2, a side elevational view of the phonograph and the mechanism connected therewith, shown as removed from the casing; Fig. 3, a reverse side elevational view of the same; Fig. 4, a plan view of the same; Fig. 5, a front view of the same; Fig. 6, a rear view of the same; Fig. 7, a broken section taken as indicated at line 7 of Fig. 2, showing a controlling wheel which serves to control the circuit of the electric motor shown and the stop-actuating lever mentioned, said view showing also the operative parts 7* "7*" adjacent to said wheel; Fig. 8, a similar view showing a different position of the parts; Fig. 9, a broken sectional view taken as indicated at line 9 of Fig. 3 and showing the construction at and adjacent to the contacts of the motor circuit; Fig. 10, a similar view showing the parts in a different position; Fig. 11, a similar view showing the parts in still another position; Fig. 12, a broken section taken as indicated at line 12 of Fig. 11; Fig. 13, a similar view showing the parts in a different position; Fig. 14, a detail of the eye and ear pieces of the machine; Fig. 15, a bottom plan view of the record-carrying disc showing the yielding stops thereon adapted to engage with the stop actuated by the lever mentioned above; Fig. 16, a detail of the record-actuating shaft; Fig. 17, a broken sectional view showing a detail of the phonograph stylus, the section being taken as indicated at line 17 of Fig. 2; Fig. 18, a section taken as indicated at line 18 of Fig. 17, and Fig. 19, a perspective view of the stylusholder with the clamping-jaws thereof separated. Sound-Reproducing Machine. Morris Keen, Philadelphia, Pa. Patent No, 929,859. The object of the invention is to provide a sound-reproducing machine of the phonograph type, which means whereby the sound box or rer producing head may travel longitudinally over the length of the record cylinder and at the same time the distribution of the sound be made by a horn supported in a fixed position, the result being that the weight of the horn is not carried to any extent by the sound box carriage and does not interfere in any way with the operation of the reproducing apparatus. B y supporting the horn separately in a machine of this class it may be adjusted at any angle or position. The weight of the horn being removed from the sound box carriage, the latter travels more smoothly and with less power. The adjustment of the machine is more easily effected and in general the apparatus is more stable and easily manipulated. This invention consists in providing a stationary bracket or arm wholly supporting the horn and combining therewith an adjustable tubular c o n n e c tion between the traveling sound box and the station ary bracket for transmitting the air vibrations to the fixed horn when embodying of construction. Fig. 1 is a plan view of a' sound-reproducing machine embodying this invention; Fig. 2 is an end elevation; Fig. 3 is a front elevation; Fig. 4 is a sectional view showing the connection of the adjustable tubular arm and bracket; Fig. 5 is a sectional view of the adjustable tubular connection or arm, and Fig. 6 is a cross-section of the plug for adjusting the sound opening to the horn. Sound Modifier for Phonographs. James Pearson, Denton, Neb. Patent No. 929,482. This invention relates to certain new and useful improvement in sound modifiers or mufflers, more especially for use with phonographs, graphophones and the like. It has for its object more particularly to >•* ; ^ 7 simplify construction, to facilitate the application of the instrument for use and provide for the ready and effective retention thereof in position when so applied. In the accompanying drawing embodying the invention Fig 1 is a perspective view thereof. Fig. 2 is a view in elevation of an instrument of the sound-producing type termed the graphophone, including its horn or megaphone, having the invention applied thereto. Phonograph. Peter Weber, Orange, N. J., assignor to New Jersey Patent Co., West Orange, N. J. Patent No. 932,200. This invention relates to a phonograph having interchangeable means for changing the relative speed of the feed screw with respect to the mandrel in a definite ratio so as to adapt the phono the general features
