PHONOGRA'PH ATTACHMENT.

Specification of Letters Patent.

Patented Apr. 12, 1921.

Application filed April 3, 1918."Seria1 No. 226,536. I

T 0 call whom it may concern Be it known that I, JAMES J. ANKER, a citizen of the United States of America, residing at Verona, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Phonograph Attachments, of

which the following is a specification.

The present invention relates to improvements in attachments for phonographs, and more particularly to the means 0 r manipu: lating the reproducer heads of such machines. For the purpose I have devised a specially constructed spider adapted to. be attached to the standard types of phonographs in current use, as will be 'fully described hereinafter in thisspecification.

In the accompanying drawings forming part of this specification I have illustrated one complete example of the physical embodiment of my invention constructed accordin to the best mode I have so far devised for the practical application of the principles of my invention.

{Figure 1 is a top plan detail view of my invention.

Fig. 2 is a front elevational view of Fig. 1.

' Fig. 3 is a rear or reverseview of the same.

Fig. 4 is a top plan view of a portion of the tone arm,,reprodu cer head and connected parts of a phonograph showing my invention in operative posltion thereon.

Fig. 5 is a front elevational view of Fig. 4. In the drawings the numeral 1 indicates the swinging tonearm of a phonograph, 2 the elbow or oose-neck member which is revolubly attac ed to the tone arm 1 at point 3, in the usual manner on such machinesl 4 the indicates the reproducer head having styusual diaphragm 5, stylus holder 6, an

lus 7.

The specially constructed spider 8 which I have devised is clearly illustrated in detail in the Figs. 1 to 3 inclusive of the drawings, and the method of attachment to the reproducer head, or sound box 4, is shown in Figs; 4 and 5. The spider 8 is made prefreadily appreciated.

head 4, and form returned portions 14, 15, 16 having holes 17 in each. The holes 17 are made of proper size to accommodate the usual screws 18 which are a regular part of the reproducer head 4, so that no changes are required in attaching my spider 8 to the ordina reproducer, head of the standard types of phonographs in current use. It

is further observed that the arms '10, 11,

etc., have suflicient depth at 19, so that they do not interfere with the parts 20, 21, etc., which are part of the reproducer or sound box head 4, the importance of which is The spider 8 is also. provided with a lifting button 22,, prefera ly having a milled edge 23, and loosely and rotatably mounted on the disk-like center 9 for a purpose stated below. Two washers 24, 25 are provided one on each face of the part 9 to take up the wear of the rotation of the button 22, and also to provide the requisite rigidity to the center of the spider,.as the latter is made of very thin and light metal and hence requires a certain amount 'of reinforcement at this point. From the above it is believed the use of the device is obvious. When it is desired to disengage the stylus 7 from the record (not shown) the liftingbutton- 22 forms a convenient and definite point at which to attach the fingers, and thereproducer head 4,

' and elbow 2 are swungabout points 3 manually until the head 4 rests on top of the tone arm 1, in the position shown dotted at 26,

Fig. 5 of the drawing. In placing the stylus'in the grooves of the record (not shown) it is evident also that the stylus can be placed gently therein, so that the record itself is not in the least injured, due to the ease of manipulation of the reproducer head 4 attained by the use of my invention. This last matter is one of importance when using the life ofthe records is also lengthened, by using my device. It is seen that by having the button 22 rotatably mounted on the spider 8 the necessity of revolving the fingers and hand is obviated when the elbow memher and reproducer head are manipulated, and this is an advantageous feature of the device.

' From the above description it is seen that I have provided a simple, practical, and in expensive device for the purpose specified, which may be readily attached to the stand,-

high priced operatic and other records, and 100 ard types of phonographsin current use, latter when revolved about a pivotal point and the utility of which is unquestioned. on the tone arm of a phono aph. 10
