' citizen of the United-States, and

of Washington, in'the DlStIlCt'Of Columbia;

lano n pram-nu, or wnsnmo'ron, menus: or conimnm Toall I I Be it knownthat I, EDGARMQBERLINER, a a resident have invented certain new-and useful Im:

movements inRecords-for Sound-Reprducing Machinery-of whichthe following is a specification. Y

of a disk record This invention appertains to improve ments in vrecord disks ,and cylinders for sound reproduclng machme's'the purpose of the invention being to provide sound records with a plurality of sound grooves and to provide each groove with perceptible means for indicating wherethe style or needle should be placed toenter a-particular sound groove or record track," the means being ofsuch a character that the operator may distinguish, either by sight orby touch the position where the style 'or needle is to be placed in order that any one of the several selections on the record may be distinguished and played.

Prior to my invention it has been proposed to make records having a sound groove which is paralleled by a second'soun'd groove, the same being known as a puzzle record, for the reason that the operator would not know and could not determine which of the two records on the disk or cylinder would be layed, and it is also old in the art to provide selection thereon, with an indented line or mark at the beginning or start of the sound groove, for the purpose of guidingthe style or needle of the reproducer into the groove, such line or mark being so minute that it is not perceptible to the touch, nor of such a character that it may be readily distin-- guished by sight. My improvement is readily differentiated from such records as a multilineal record made in accord with my invention has thereon indicating means, whereby the operator may distinguish one groove or selection from another and so place the style or needle that it will enter a particular sound groove and reproduce the chosen selection, and in carrying my invention into practice, the perceptible'means for distinguishing one sound groove or selection from another are dlfi'erently colored and spaced and they are also positioned either above or below the plane of the sound grooves.

In the drawings Figure 1 is a plan view made in accordwlth my ins ammin of Letters nuns. I nrrllcctioiiilledbetcbcr 8, 1008'. Sma l.

vention, the perceptible indicating means being within the space occupied by the sound- "grooves an positioned concentric to the center of the disk, Fig, 2 is .a transverse section on the line'o-b,"of Fig.1, Fig. 3 is a plan view of another ,form of my invention, the center ofthe disk being colored, and with this form or my invention the outer border will have raised indicators formed thereon. Fig. 4 is a side elevation of a part of the disk shown by Fig.3. Fig. 5 is a fragmentary plan view of a further modification, Fig; (i is a section onthe line -6-6. Fig. 7 is a fragmentary plan view of another modification, and Fig. 8 is a side elevation of the construction shown by Fig. 7.

Referring to the drawings 1, 2, and 3 indicate the sound grooves of the record,such grooves being spiral and parallel, and in practice the inner and the outer margins 4 and 5, may be raised or above the plane of the face of the disk into which the sound grooves are impressed. The margins or f dead spaces 4; and 5 are the portions of v the disk or record upon which I apply the perceptible indicating means, each sound groove or selection having an indicator which diifers as to position or appearancefrom the others.

Upon Fig. 1 of the drawings, the disk record is provided with sound grooves 1, 2, and 3 and uponthe inner margin or dead space 4 of the disk I provide raised and differently colored indicating means 11, 12, and 13 the bein concentric to the axis of rotation ot the tfisk. The raised indicator 11 may be colored blue and is positioned relative to the commencement of the sound groove 1, so that the operator may place the style or needle upon the dead space to enter such groove/and reproduce the selection recorded by such groove. The indicator 12 may be white, and the thirdone may be red; It will be observed that the indicators are out of line and bein near the center of the disk, where the spec is the lowest, theythe axis of rotation of the disk. The disk shown by Fig, l may have a raised outer border or mar 'n, the surface thereof bein on the same p ane as the upper surface 0 the indicators 11,12 and 13.

Fi 3 shows a further form of my invention n which the centerportion of the disk is colored, and upon the outer border 5,-areraised portions 14, and 16, one for each of the sound grooves. The raised port ons 14, 15 and 16 are concentric to the center of the disk and are adapted to guide the style or needle to a groove that joins the sound goove. If desired the raised portions may joins one of the sound grooves, and each disk will be provided with as many of these raised portions as there are sound grooves or selections upon the disk, and the groove or recess 17 may becolored;

Fi 7 shows a further modification of the inventiomand in this example of my 1mprovement, the border of the disk is cut away to provide depressions 19, the same having longitudinal and inward inclined bottom surfaces, to lead the style or needle to a guide groove 18, and the bottom of the recesses maybe colored by being painted or otherwise. r

In practice the center space of the disk not occu ied by the indicating means will carry a abel having marks corresponding with marks or other indic'ia placed adjacent to the indicating means, set forth, and the indicating means are on a different plane from the surface of the dead space of the disk and are preferably located to be out of line in the direction of the travel of the disk,

and by means of the invention set forth the record disk is provided with a plurality of indicators which will be erceptible to the touch and si ht, and enab es the operator to place the sty e or needle to play the desired selection or groove of the record in the dark.

My invention may be readily applied to sound record disks in which the sound grooves shown'in atent No. 785,191 issued to Herbert S. Berliner, March 21, 1905.
