SOUND-BOX FOR TALKING-MACHINES.
Specification of Letters Patent.
Patented Aug. 11, 1908.
Application filed November 14, 1907. Serial No. 402,058.
"To all whom it may concern:
7 weight may I gas The upper Belt known that I, EDWARD D. G LnAs'oN, a o1t1zen of the United States, and a resident of Moores, Delaware county, Pennsylvania,
have invented certain new and useful Impfovements in Sound-Boxes for Talkingachines, clear, and complete disclosure.
This invention relates to improvements in sound boxes for talking machines, and has for its main object to provide a box having an improved stylus mounting whereby a be used to counterbalance the stylus.
Other objects will appear in the following description. i The invention consists in the novel construction, combination and arrangement of parts hereinafter set forth and articularly pointed out in the claims and il ustrated in the accompanying drawings, in which Figure 1,is a front elevation of a sound box constructed in accordance with this invention; Fig. 2 a longitudinal section of the same on line 22 of Fig. 1; Fig. 3 a front elevation of a modified form of this invention and Fig. 4 a longitudinal section on line 44 of Fig. 3.
Referring to the drawings, my improved sound box comprises the usual casing 1, in
the bore of which is supported the usual diaphragm 2, which is held in place by means of gaskets 3, 4, the bore of the sound box being provided adjacent its outer edge with a V- shaped annular groove 5, to receive the outer et 3, which is sprung into place, the in nor gasket 4 resting between the inner cylindrical wall and the rear wall of the box and holding the diaphragm against the outer gasket.
The stylus bar has, as is usual, a cylindrical lower end. 6, provided with a longituthe recc needle 8, which is held in p are by the screw 9. part 10 of the stylus baris flattened in a dlrcction dongitudinally of the box and tapered'toward the axis of the box where it is divided into two branches, one of which, 11, extends axially of the box and is adapted to form the connection between the stylus bar and the diaphragm, being honctically connected at its outer end to t is diaphragm by wax '12 or any other well-known means, and.
the other branch 13 extends in the same direction as the main portion of the bar, up-
of which the following is a full,
tion of the stylr wardly, and projects beyond the outer periphery of the'sound box casing. This portion of the bar is preferably of unil orn. di-
tened portion of the stylus bar being pro' vided with a lateral extension 17 carrying trunnions 18, the ends of which lie between the said lugs 16 u on the sound box. casing, and being pivota ly connected thereto by means of set screws 19 having conical inner ends which rest in suitable sockets in thocnds of the trunnions. The lugs upon the sound box casing and the pivots are preferably arranged as illustrator l, to bring the ax is of oscillation of the stylus bar substauitiallyin the plane of the diaphragm, and tho stylusis thus free to vibrate in a plane perpendicular to the diaphragm, the motion of the inner end of the connecting arm 11 being also substantially perpendicular to the lane of the diaphragm.
The function of tic movable weightv 14 u on the stylus bar is similar to that of a fly w ieel upon an engine, in that it takes up the energy transmitted by the movement of the stylus at the bcginnil'ig of the movement of the stylus in one direction, giving out the energy again at the end of the movement of the stylus t?) continue the motion of the upper end of the stylus bar in its original direction, thus increasing theamplitudc of vibration of the diaphragm. A further function of the Weight is to keep, the stylus needle in close contact with the surface of the record groove by which it is being moved during its motionin either direction.
In Figs. 3 and 4.1 have illustrated a modified form of this invention, in which the upwardly extending arm of the stylus bar shown in Figs. 1 and 2 is omitted, and an arm 20,
lower portionof t o stylus bar in a direction substantially parallel to the axis of the sound box, the weight 21 in this case being slidably mounted upon the arm 20, and 'lixod in any desired position by the set screw 22, to act upon the stylus, as already explained. This arm 20 is iivotod bctwoon lugs 23, extending downwarr. ly from the sound box casing by means of the set screws 24 having conical fixed position by .for a similar pur )ose, is extended from the points fitting into corresponding sockets of l the said arm 20. The axis of oscillation of l the stylus bar in this modified form is preferably arranged in the plane of the diaphragm to permit the stylus bar to vibrate in a plane perpendicular to the diaphragm as heretofore explained for the previous form of this invention. The omission of the upwardly extending arm of the stylus bar renders it unnecessary to have a right-angled connecting arm between the stylus bar and the diaphragm, the upper end of the stylus bar being curved'inwardly and phonetically connected to the diaphragm at 25, as usual.
It is obvious that this style of sound box may be used in connection with either records having vertically undulating grooves or with records having laterally undulating grooves, and it is furthermore obvious that many changes might be made in the details of construction of this box beyond what I have shown and described, within the scope of the appended claims, without departing from the spirit of this invention, or sacrificing any of the advantages thereof.
Having thus fully described my invention, what I claim and desire to secure by Letters Patent of the United States is:
1. In a sound box, the combination with a diaphragm of a stylus bar, an arm phonetically connected at one end to said dlaphragrn and at its other end to said bar, an arm forming part of said'"bar extending outwardly casing, of a diaphragm,
from the axis of said box, and a weight slidably connected to the outer end of said arm. t
2. In a sound box, the combination with a diaphragm of a stylus bar, an arm phonetic- 1 ally connected at one end to said diaphragm and at its other end to said bar, an arm forming part of said bar extending outwardly from the axis of said box, and means connected to the outer end of said arm to counterbalance said stylus bar.
3. In a sound box, the combination with a casing, of a diaphragm, a stylus bar pivotally connected to said casing and phonetically connected to said diaphragm and a weight mounted upon said bar to counter balance the same.
4. In a sound box, the combination with a casing, of a diaphragm, a stylus bar pivoted to said casing and phonetically connected to said diaphragm, an arm extending from said bar and integral therewith and a weight upon said arm. 1
5. In'a sound box, the combination with a casing, of a diaphragm, a stylus bar pivoted to said casing and phonetically connected to said diaphragm, an arm extending from said bar and integral therewith and a weight slidably mounted u on said arm.
7. In a sound ox, the combination with a casing, of a diaphragm, a stylus bar pivoted adjacent one end to said casing, and phonetically connected axially of said casing to said diaphragm, an arm integral with said bar extending outwardly from the axis of said casing, and a weight upon said arm to counter balance said stylus bar.
8. In a sound box, the combination with a a stylus bar pivoted adjacent one end to said casing, and phonetically connected axially of said casing to said diaphragm, an arm integral with said bar extending outwardly from the axis of said casing, and a weight adjustably mounted igpon said arm to counter balance saidstylus 9. In a sound box, the combination with a casing, of a stylus bar having a rearward extension provided with oppositely extending trunnions having sockets in the ends thereof, lugs u on said casing projecting over the ends 0 carried by said lugs and engaging in said sockets to support said bar.
10. In a sound box, the combination with a casing, of a stylus bar mounted to oscillate upon said casing, and a weight mounted upon said bar to counterbalance the same.
11. In a sound box, the combination with a casing, of a ri id stylus bar mounted to oscillate upon sai casing, and a weight mounted upon said bar to counter-balance the same.
12. In a sound box, the combination with said trunnions, and conical bearings
