TALKING-MACHINE.

Specification of Letters Patent.

Patented Apr. 10, 1917.

Application filed September 4., 1907, Serial No. 391,399. Renewed February 5, 1912. Serial No. 675,646.

To all whom it may concern:

Be it known that I, JOHN C. ENGLISH, a citizen of the United States, and a resident of the city of Camden, county of Camden, and State of New Jersey, have invented certain new and useful Improvements in Talking-Machines, of which the following is a specification.

The main objects of this invention are to provide in a talking machine improved sound amplifying means; and to provide other improvements as will appear hereinafter.

In the accompanying drawings Figure 1 is a fragmentary side elevation partly in vertical longitudinal section of a talking machine constructed in accordance with this invention; Fig. 2 is a perspective of a sound amplifier constructed in accordance with this invention; Figs. 3 and 1 are perspective views of two different forms of sound amplifiers constructed in accordance with this invention; and Fig. 5 is a longitudinal horizontal section of a sound amplifier constructed in accordance with this invention.

Referring to the drawings, one embodiment of this invention comprises a cabinet 1 provided at the upper end thereof, with a top compartment 2 inclosed by a hollow cover 3. The top compartment 2 contains a rotary record support or turntable a, a sound box or sound reproducer 5 arranged to codperate with a sound record 5 on the record support 4:, and a hollow tapering tone arm or sound box arm 6 connected at its smaller end to, and communicating with, the sound box 5. The tone arm 6 is mounted to swing with the sound box 5 across the record support at about a vertical axis extending through the larger end of the tone arm. The larger end of the tone arm 6 turns downwardly and communicates with the upper end of a sleeve 9 passing snugly and fixedly through a partition 8 forming .the floor of the top compartment 2 of the cabinet, the axis of oscillation of the tone arm 6 being coincident with the longitudinal axis of the sleeve 9.

For amplifying the sounds delivered from the sound box 5 through the tone arm 6 and sleeve 9, there is arranged within the cabinet, below and extending downwardly from the floor 8 of the top compartment of the cabinet, a hollow longitudinally curved rigid bracket 10. The upper end of this bracket 10 is provided with a circular inlet 10, which registers and communicates with the lower end of the sleeve 9, and the upper end of the bracket is also provided with a flat horizontal flange 11 integral or rigid therewith and rigidly secured to the under side of the partition 8 by means of screws 12, or in any other suitable manner.

The bracket 10 flares downwardly and forwardly from its upper end and terminates in a transversely oblong substantially rectangular lower end 13, provided with a plurality of spaced openings or outlets 13' communicating with the interior of the bracket and forming sockets in which are secured the inner ends respectively of a plurality of tubes or resonators 14 which are entirely supported by the bracket 10, and which project freely in the interior of the cabinet from the bracket. These tubes or resonators 1 1 taken together with the bracket 10 form a sound amplifier.

The longitudinal opening through the bracket 10 increases gradually downwardly in transverse sectional area and changes gradually from the circular shape of the inlet 10' to the oblong rectangular shape of the interior of the lower or outlet end of the bracket. The outlets 13' of the bracket are preferably rectangular and substantially square in outline, forming sockets which are substantially identical in size and form and which are preferably arranged in horizontal alinement. The portions 15 of the bracket between the outlets 13, and the adjacent portions of the inner surfaces of the walls of the resonators 14, preferably converge in wardly and terminate respectively in sharp substantially vertical edges 15', arranged to facilitate the entrance of sound waves into the resonators 14.

The tubes or resonators 14: may be circular in cross section, as shown in Fig. 2, or hexagonal as shown in Fig. 3, or rectangular or square, as shown in Fig. 4:; or any other desirable shape in transverse section through the major portion of their lengths, and may be of substantially equal lengths, as shown in Fig. 2, or of unequal lengths, as shown in Figs. 3 and 4, and may have sides or walls either of uniform thickness, as shown in Figs. 2 and 3, or of different thicknesses, as shown in Fig. 4;, as may be preferred for any particular purpose.

It is to be understood that this invention the inner ends of the tubes or resonators 14 i are preferably exteriorly identical in construction and adapted to fit in sockets of uniform sizes, so that any of the several forms of tubes may be used with one type of bracket 10, thus permitting any desired combination of tubes with a single type of bracket.

From the foregoing it is evident that an amplifier may be constructed in accordance with this invention by combining the bracket 10 hereinbefore described either with a series of similar tubes of like material, or of different materials, or by combining the bracket 10 with a plurality of tubes of various shapes and of various or like materials.

It has been found that when a plurality of tubes or resonators are used simultaneously, as hereinbefore described, in an amplifier for the sounds transmitted from the sound reproducer of a talking machine, the tubes or resonators supplement each other in acting on the complex tones and over tones transmitted from the reproducer, and tones or over tones which might be unaffected or subordinated in one of the tubes, are apparently taken up and acted on by some other tube or tubes, and that all of the tubes thus working together will give a pleasing round full mellow quality to the reproduced sounds.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States is:

1. In a talking machine, the combination with an amplifier comprising a hollow stationary sound conveying bracket of relatively non-vibratory construction provided with an opening at one end and a plurality of openings at its other end, of a sound box communicating with said first mentioned opening and a plurality of spaced resonators communicating with the said plurality of openings respectively.
