Figure 1 is an elevation of a phonograph sound record disk and a booklet containing in readable form the complete translation of the record disk contents; the booklet being applied to the disk.

Figure 2 is a sectional view illustrating the parts shown in Figure [assembled for use in the playing of the record disk.

Figure 3 is a perspective view of the envelope,

Figure 4 is a perspective view of the booklet opened.

The present invention contemplates the association of an instructive booklet 10 or the like with a sound reproducing means such as a sound record disk 11, and suitable means for effectin the association such as a disk shaped enve ope 12.

The sound record disk 11 is of the usual type and therefore has a spiral record groove 13 therein as an impression for reproduction of a musical or speech composition or both; the disk being used in conjuction with a sound reproducm instrument such as a phonograph. The dis 11 has a spindlehole 14 centrally thereof.

In order that a person may be fully familiar or conversant with the matter contained by the record disk 11 there is provided the mentioned booklet 10' which contains in readable form the matter aforesaid. The booklet 10 has a hole 15 therethrough, that is tosay, a hole through the covers and pages thereof substantially equal in diameter to the hole 14.

In order that the booklet 10 may be associated with the record disk 11 there is provided the mentioned envelope 12 which in the present instance consists of twoflpieces of the same material connected to each other by virtue of the tabs 16 cut out of one piece of material and pasted to the marginal edge of the other piece of material thus providing sides 17 each of which has a hole 18 therein. The holes 18 are alined and each is substantially equal to the diameters of the holes 14 and 15. The envelope is attached to the disk 11 centrally thereof by virtue of glue or the like 19 on one of the sides 17 the holes 15 being alined with the hole 14. It will now be manifest that the booklet 10 may be readily inserted in the pocket of the envelope 12 or be removed therefrom..

1n playing a particular record disk, it is possible in accordance with the present invention, to keep a booklet with words and music of the composition recorded on the record disk so that the booklet is available for perusal in self instruction in the contents of the record disk, leading to fuller understanding of such contents. The booklet may be kept in the envelope attached to the record disk even in the playing of the latter without in any way interfering with the positioning of 'the recorddisk on the turn-table'of a phonograph about the s indie thereof by reason of the holes 15 an 18 which may be brought into alinement with 5 the hole 14 of the record disk.
