4 A. FISCHER. SO-UN'D BOX FOR TALKING MACHINES. APPLICATION FILED 0GT.18,1909.

my Patent #904,523, November 24,, 1908.
circle, the radius of which is equal to the SOUND-BOX FOR TALKING-MACHINES.
To all whom it may concern:
Be it known that I, ALEX FISCHER, a subject of the King of England, residing at 8 Maclise road, Kensington, in the county of London, England, have invented certain new and useful Improvements in the Construction of Sound-Boxes for Talking-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to sound. boxes for talking and like machines and has for its object to improve the connections between the stylus bar and sound box disclosed in To these ends the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.
Referring to the accompanying drawings forming a part of this specification in which like letters refer to like parts in all the views :Figure 1 is an elevational view of a sound box made in accordance with my invention; Fig. 2 is a side view of the same; Fig. 3 is a sectional detail view of certain parts; Fig. 4 isa perspective view of the spindle and connecting parts; Fig. 5 is a view of a modified form of the invention; and Figs. 6, 7, S, and 9 are views of the bearings for the spindle.
a is the shell of the sound box provided with convex bearing surfaces formed of thin plates or blocks b. It will be observed from the various figures that these bearing surfaces Z) are convex instead of concave as in my patent above, and form parts of a vertical distance between the point of connection of the stylus bar with the dia- 'phragm and the surface of the spindle nearest thereto.
0 is the spindle which may be circular, partly circular, rectangular or of any other convenient shape in cross section.
71 shows the spiral controlling springs, it shows hollow nuts and f shows a small arm. The arm f projects inwardly from. the spindle toward the sound box, and the spiral controlling springs in are above the axis of the spindle as shown at Figs. 1 to 4. he shell of the sound box may be hollowed Specification of Letters Patent.
Application filed October 18, 1909.
Patented Jan. 2, 1912.
Serial No. 523,243.
out to accommodate the small arm f, see Fig. 8.
To render the mounting of the end of the spindle c, which is farther from the springs 70, more eflicient, I fix to the underside thereof, that is'the side opposite the shown in my patentbeforc mentioned are dispensed with and in their place a second flat spring 9 is attached at the side of the spindle opposite the bearing surfaces and at the opposite end to the first spring 9.
Referring to the'details shown at Figs. 6 to 9, Fig. (3 shows a convex bearing with a partly circular spindle end resting thereon. Fig. 8 shows a convex bearing with the spindle end rectangular in cross section resting thereon. Figs. 7 and 9 show two forms of bearing surfaces, which may be formed of thin metal plates, as will be seen from Fig. 7, or thicker plates with beveled edges, as shown in Fig. 9, so as to reduce the bearing surface to a desiredsuitable size.
Although I have explained my invention as applied to a sound box such. as that described and shown in the specification of my former aforesaid Letters Patent, 1 wish it to be understood that I do not intend to confine the application of the heroin specified improvements to such sound boxes, only, but I desire it to be understood that 1 may employ convex bearing surfaces with spindle ends circular, partly circular, rectangular or of other suitable shape in cross section also with sound boxes of other construction.
By the construction shown the spindle c has both a rocking movement on the curved bearings and also a pendulous-like swinging movement thereon alllfill enables the needle to follow the record accurately and respond thereto wi h great delicacy so that the finest shades of tone maybe reproduced by the diaphragm.
What I claim and desire to secure by Letters Patent of the United States of America,
1. In-a sound box for talking machines,
the combination with a casing and its diaphragm of a stylus bar attached to the diaphra'gm, a spindle carried by the stylus bar, and a pair of convex guide bearings for the spindle on the casing each having a bearing surface curved in the arc of a circle whose movement thereon.

In a sound box for talking machines, the combination with a casing and its diaphragm of a stylus bar attached to the diaphragm, a spindle carried by the stylus bar, a pairof convex guide bearings for the spinon the casing each'having a bearing surdius is approximately equal to the distance between the point of connection of the stylus bar with the diaphragm and the surface of "the spindle nearest thereto, and adjustable yielding devices pressing against its bearings.
3. In a sound box for talking machines, the combination with a casing and its diaphragm of a stylus bar attached to the diaphragm, a spindle carried by the'stylus bar, a pair of convex guide bearings for the spindle on the casing each having a bearing surface curved in the arc of a circle.whose radius is approximately equal to the distance between the point of connection of the stylus bar with the diaphragm and the surface of said spindle the spindle nearest thereto, an arm projecting inwardly from the spindle toward the casing, and yielding devices carried bythe casing pressing on opposite sides of said arm.
In testimony whereof, I affix my signature, in presence of two witnesses.
