Description

J. I. BUFFA' GRAPHOPHONE ATTACHMENT.
APPLICATION FILED MAY 7. 1917 Patented o'ct; 23,1917.
QTTU/QNEY urn J AMES I. BUFFA, OF SAN FRANCISCO, CALIFORNIA.
ennrnornonn .a'r'rncmvrnn'n- Specification of Letters Patent. Patented Oct, 23, 19%1'7,
Application filed May 7, 1917. Serial No. 166,8441
cisco and State of California, have invented new and useful Improvements in Graphophone Attachments, of which the following is a specification.
The present invention relates to improvements in talking machines, and especially in Edison disk phonographs.
The object of the invention is toprovide means, automatically operating with the movement of the reproducer, to remove the dust from the record in front of the reprodueer.
In the accompanying drawing, Figure 1 is a broken plan view of an' Edison phonograph disk, the reproducer thereon and my improvement attached thereto; Fig. 2 is a perspective-view of said reproducer and ;attachment; Fig. 3 is a broken bottom plan view thereof; Fig. 4 is a perspective View of the attachment detached; Fig. 5' is a broken perspective view of the reproducer arm; Fig. 6 is a broken perspective view showing a modification.
Referring to the drawing, 1 indicates a record, 2 the reproduc'er, and 3 the soundconductin tube of an Edison disk phonograph, 4 indicates the weight, carrying at one end the diamond point 6, and connected at the other end with one end of a spring metal strip 7 Theother end of said spring strip is secured between a rotary member 8 and a block 9. The rotary member 8 is retatable about a shaft 11, secured in a boss or enlargement 12 formed at the smaller end of a tapering arm 13 of the reproducer 2. The block 9 is secured on the lower side of said spring strip 7 by means of screws 14 extending through holes in said block and screwed into said rotary member, in which is also secured a fixed pin 15, which is ieceived in a socket in the block 9. 16 indicates a brush holder and 17 a brush held thereby, said brush holder being formed of a strip of metal of which one end 18 is.
' reduced in diameter and bent back on itself,
as shown at 19, to form a clamp for clamping one half of the brush, while a tongue 21 is cut out of the metal and bent back upon itself toward said reduced end to 'form a clamp for clamping the other half of the brush.
Said holder is so bent so that the portion holding the brush extends at an angle of about 40 with the vertical and also extends in a plane making about 40 with the reproducer arm 13, while the other. end of the holder is held horizontally between the block 9 and the spring metal strip 7.
A brush so held will be in the proper position to brush the dust out of the grooves in the record at points in advance of the reproducing point 6. 1
In the form of the invention shown in Fig. 6 the brush holder is extended toform a band QQ-fitting closely around the small end of the reproducer arm 13 close to the boss 12 on said arm, the terminal portion of said holder, after passing around said arm, being firmly secured by a screw 23 and nut 24 to a mediate portion of said holder between the arm and the brush.
As the Iniison disk phonograph records have grooves which are considerably shallower than those of otherrecords, it is very important that these grooves be kept free of dust, which impairs the tone of the phonograph.
In the "use of my invention this is done automatically and without necessitating any alteration in the construction of the phonograph.
1. In combination with the arm of a reproducer of an Edison phonograph, a pivot secured in an end of said arm, a spring metal strip for carrying the weight, and "a block secured to'said strip and arm, of a brush holder, and a brush secured in one end there of, the other end being secured between said strip and block.
1 2. In. combination with the arm of a re producer of an Edison phonograph, a pivot securedat an end of said arm, a spring metal strip for carrying the weight and a block, and screws securing said block to said stri and arm, ofv a brush holder 'and a brus secured in'one end thereof, said screws also securing the other end between said strip and block.
