TALKING-MACHINE.

Application filed May 3, 1913. Serial No. 765,221.

To all whom it may cones/"1n.

Be it known that I, CHARLES L. HInBAIu), a citizen of the United States of America, residing at Philadelphia, in the county of -Philadelphia and State of Pennsylvania and arrangement, the cabinet or casing in my present machine is utilized as a soundamplifier and is intended to serve no other purpose, the reproducing mechanism being mounted eXteriorly thereof but in such relation as to cotiperate therewith. This arrangement of elements enables me to give the cabinet or casing the form best adapted to serve as an amplifier-of the reproduced sound and permits a machine to be produced having good lines, a graceful appearance and which occupies comparatively small space and is highly efficient in reproducing sound and imparting the required amplified effect to render it clearly audible and pleasing to the ear. In the present machine, no attempt is made to obtain a concealed horn effect but, on the contrary, the amplifier is in full view and accessible for purposes of examination, repair, cleaning, etc.

A preferred form of machine embodying my invention is illustrated in the accompanying drawing. I wish it understood, however, that I do not limit myself to the same, as various changes may be made therein or other forms employed without departing from the spirit and scope of the present invention.

In the drawings-Figure l is a vertical longitudinal section, and Fig. 2 is a plan view, showing the sound amplifying passage by dotted lines.

Referring now to the drawings, 1 represents a rotatable record support in the form of a turntable carried by a shaft 2 which is driven by a motor,.indicated diagrammatically at 3, and 4 is a disk record on the table. Cotiperating with the record 4 there is a sound-box 5, suitably mounted to have the necessary freedom of movementto adapt itself to'inequalities of the record and track in the groove thereof.

Specification of Letters Patent.

Patented Mama-$13.

The particular form of sound reproducing mechanism above describedforms no part of illustration only.

As shown, the reproducing mechanism is arranged exteriorly of a casing or cabinet (3, and mounted on a front bracket or extension 7 thereof.

As above stated, the casing or cabinet is intended to be utilized as a sound-amplifier and to serve no other purpose, being shaped or divided interiorly to provide a continuous and gradually enlarging back and forth passage 8, leading from the sound-box rear- Wardly throughout the entire length of the casing and returning and terminating at the front thereof for the delivery of amplified sound either or both above and below the turn-table, as indicated by arrows.

While I have shown a straight back and forth sound-amplifying passage leading.

from the front to the rear of the casing and .ness of construction of this machine, its compact form, graceful and pleasing appearance, the convenience with which it may be examined, repaired, operated, etc., and its high efliciency in reproducing and amplify ing sound, give it important advantages over many machines now on the market and m use.

As'the operation will be apparent from the foregoing, further description of the same will not be given.

Having, therefore, described my invention, I claim:

1.. In a talking machine, a casing, sound reproducing means located exteriorly of and supported by the casing, means within the casing dividing the interior thereof into a back and forth sound amplifying passage providing a plurality of exit portions, and a tone-arm communicating with said passage, operatively connected to said reproducing means, the inlet portion of said passage being intermediate said outlet portions 2. In a talking machine, a casing, sounc reproducingmeans located exteriorly of'and supported by the casing, means within the casing dividing the interior thereof into a back and forth sound amplifying passage providing a plurality of exit portions, and a tone arm operatively connecting said passage with sai sound reproducing means, the inlet portion of said passage being intermediate said outlet portions and one of said outlet portions extending beneath said reproducing means.

3. In a talking machine, a casing, exteriorly located sound reproducing means supported by the casing, a back and forth sound amplifying assage formed interiorly of the forward end of the casing on either side of 29 the reproducing means; and a tone-arm operatively connecting the reproducing means with the inner rearwardly extending section of the sound amplifying passage.
