The 'plete QlreceiVes the horn 23 which is fastenedfrrnlyn. asy A bycarlningg:to .theboardgfnnd `herlelbe observed y"clizit .the top v board.' loyenlingstlie 1 .af @per sop-'enf and spaced from the lower end of the tube 18. In this way I provide an air inlet opening 26 between the horn chamber and the interior of the horn.
In the present application I have shown the opening 26 as non adjustable but in this connection wish to state that in a co pending application Serial 287,582 filed May 3l, i918 I have shown it as adjustable so that the amountof air admitted vat this point can be controlled. 'Under ordinary conditions however the extent of the opening would be standardized so that the various sizes of machines would have openings to suit the condition existing.
The horn-23 has the inner end fastened, as above explained,ito the bracket and the outer or delivery end is mounted in the usual wayin the front of the casing. The neck of the horn is reinforced by making it thicker .than the delivery or iiariiig Aend and in this connection reference, ismade particularly to Figures 4, 5 and 6 of the drawings where it will be seen that the upper end at the bracket is, comparatively speaking, very thick and heavier at the front than at the back, and that below the bracket it gradually decreases in thickness on the front side but retains the same thickness at the back. rlhis formation is an important one as I find that by reinforcing'in this manner I greatly improve the value of the horn in so yfar as the delivery of thesound waves are concerned.
Directly beneath the' neck of the horn I place a reinforcing post 2,7 which vis permanently mounted on the partition 8 and has the upper end gouged out as indicated yat 28 to fit accurately the underside of the neck. This post forms ai solid support for the base of the neck at the point where the sound waves are being deflected to the flan ing end of the horn. In actual practise form' the post from a nr ber of wooden strips securely fastened together such as by nailing. This feature is not claimed herein but is'made the subject of a separate application, Serial `#498,387 hled Sept. 3, 1921. In order to close off the yback end of the horn chamber I have placed a vertical pai'- tition 30 across the chamber slightly in advance of the post and bracket and have cut the opening 3l in the partition to admit the horn, the opening being somewhat larger than the horn at this point. I then place a fabric indicated at 32 between the horn and l the side of the openinof to close off the spaces and'entirely separate the back ofthe chamber' from the front.
I have found in machines which I have constructed with an air shaft'that there is a natural air draft established from the iloor upwardly through the shaft to the passage 26, such being due However, if 't is desired to have a more or less strong draft one can place' an electric to the difference in levels l. The combination with the delivery end of the'sound box tube of atalking machinel and a horn having the receiving end thereof spaced from the delivery end ofthe sound box tube to provide anair inletv opening of an air shaft communicating with the inlet opening. i
2. The'combination with the delivery end of the sound box tube 'of a talking machine and a horn having the receivingl end vthereof surrounding but spaced from the delivery end of they tube to 'provide an air entrance betweenthe tube and the-horn at the Areceiving end of the horn, of an air shaft built in the body of the machine and communieating with the air passage 'and with exterior air.
3. In a talking machine, the combination with the horn chamber, a horn mounted in the chamber and a sound box tube entering the'chamber and extending into the re ceiving end of the horn, but spaced `therefrom to provide an annular air inlet passage surrounding said tube of an air shaft opening to the horn chamber.
4c. Ina talking machine, the combination with a case, a horn and a sound box tube,
of a bracket permanently secured to the back of the case and receiving and supporting the receiving end of the horn, an
upwardly flaring tube carried by the bracket and located at the receiving end of the horn and continuous therewith and an open ended stationary cylindrical tube continuous with the delivery end of the sound box tube and entering the flaring tube and of smaller diameter than the flaring tube'to provide 4an inlet passage to the horn and surrounding the cylindrical tube.
v5. In a talking machine, the combination withV a case, a horn and a soundvbox tube,
of a horizontally disposedv bracketpermanently secured to the backk of the'casevand receiving the receiving end of the horn, an
upwardly flaring tube permanently seated in the top side of the vbracketf'and having the lower end 'engaging the f horn f and' l with 1 an internal diameter equal tothe internal diameter of the receiving end of the horn and 4an open ended cylindricall tube continuous with the delivery end of the sound box tube and having the lower end thereof entering but spaced from the inner Wall ofthe 'flaring tube, therebyprovidingan annular inlet passage between the tubes.
' 6. In talking machines, a tone arm, and
an amplifying horn, the large end of they tone arm ending adjacent thesmall end. of
the horn in acoustic relation to each otherI but spaced apart without physical connection therebetween, whereby extraneous air is admitted to the horn at this point without encounterinor obstructions of any kind.
7. In talking machines, a tone arm, an
horn 1n a spaced apart, acoustlc relatlon to the tone arm forming an annular amplifying opening between them, a sound box o-n the tone arm adapted to produce sound waves -for transmission through the tone arm across the space into the horn, and means external of the horn for enc1rcl1ng such sound waves by an enclosing and commgllng column of vair at the end of the tone arm and delivering the combined sound waves and air to the horn. t
8. In talking machines, `a tone arm, a horn having its recelvmg end spaced apart from the tone arm but in acoustic. relation therewith, means for supporting said meinbers in operative relation to each other eX- traneously of the adjacent -ends of said horn and arm'whereby an unobstructed air-'pas'- sage is formed cat-ing air passage in connection with the former, and means for conveyingV air through such passages to thehorn."
9. In talking machines, a tone arm, a
