Description

tion consists in certain constructions and' arrangerrients .of the parts that I shall here'- inafter fully describe and claim.

Fora full understanding of the' invention,` reference. is to be had to the following description and accompanying drawings, in which Figure l is a longitudinal sectionaliview of a phonograph embodying the improvements of my invention; Fig. 2 is a horizontal sectional view thereof; and, Fig. 3 is a detail sectional View illustrating a deflector that is (.orresponding and like parts are. referred to in the. followin description and indicatedH in all theviewso the drawings by the same reference characters.

'lhe cabinet of my improvedphonograph comprises a bottom l, aback 2, two sides 3, a front 4, and a lid or cov'er 5 which may be hinged to swing upwardly at its front end, as shown.y This cabinet may be made of any desired wood or other material and is the shell in which my. improved sound amplifying means are fitted.

The sound amplifying means of my uwention is preferab y constructed entn'ely of rubber, either hard or soft, preferably'thc former. Except its top, it is formed of one casting, preferably, and embodies l sides 7 that extend parallel throughout the major portion of their length, a boitoin plate G, webs 8 between the two sides and dlvergixig forwardly so as to form with the sides outwardly llared sound passages, said webs being comlected together at their front ends by a cross web E), and curved walls l0 which form divergent branches from the lower end of a laterally elongated or elliptical opening ll. atthe rear of the casing, a deflector 12 asbest seen in Fig. 3, being mounted in said -soas to deflect the sound laterally and forwardly through the branches 1() to Specification of Letters'latent.
