SOUND-RECORD FOR TALKING-.MACHINES. 1

Specification of Letters Patent.

Application filed September 6,1910. Serial No. 580,670.-

Patented Apr. 22, 1913.

To all whom c't'may concern:

Be it known that I, CLARENCE S. WICKES, a citizen of the United States, and a resident of the borough of Merchantville, State of New Jersey, have invented certain 'new and useful Improvements in Sound-Records for Talking-Machines, of which the following is a full,clear, and exact disclosure, reference ess of-manufacture, and isliable to warp. during its subsequent use. This warping ap:

to the marginal: rib, whereby as the record being had to the accompanying drawings, forming a part of the followingspecification.

thereof; and to provi e other improvements,

as will appear hereinafter.

It has been discovered after numerous exriments, that a compressed disk record aving arelatively' thin body portion provided upon its back with a marginal rib and with radial or transverse reinforcing ribs .extendingfrom the central portion of the rewrd and connected with the marginal rib at their outer ends, tends to warp as it cools after being taken from the press in the procpears to be due to the fact that the outer ends of the radial or transverse ribs are. connected cools, the rim of the record is drawn slightly rearwardly, and the face of the record is caused to assume a convex shape.

One of the objects of this lnvention is to overcome this tendency to warp, which is found in the ribbed back record as heretofore constructed, during its process of manufacture and during its subsequent use, and I have found that whenthe i marginal rib is omitted in a record of this kind and. the

' radial ribs are retained, that this tendency of the record to warp is eliminated. This omission of the marginal rib, however. obviously deprives the record of some of its strength at its edge.

I have also. discovered after various experiments, that a thin ribbed-back record having the desired qualities of rigidity and strength and having a flat recorded surface, may be provided by constructing the record with a marginal rib and also Wltllradial or transverse ribs extending from the central portionof the back of the record outwardly, and the outer ends of which are not connected with the marginal rib.

Furthermore, I have discovercdthat in the latter construction and also in the construction in which the marginal rib is omitted, or in other constructions, transverse or radial ribs which have their outer ends connected to the marginal rib or extending from the margin of the record, and their inner ends spaced from the central portion of the record, may be used to advantage to strengthen the record and to prevent warp- 1ng.;

In the accompanying drawings, Figure 1 is a diametrical section of a sound record constructed in accordance with this invention; Fig. 2 a fragmentary bottom plan vieW or rear elevation of the same; Fig. 3 a fragmentary top plan view or front elevation of the same; Fig. 4 a diametrical section of a modified form of this invention; Fig. 5 a

fragmentary bottom plan view of Fig. 4, the top plan view of Fig. 4 being the same as shown in Fig. 3; and Figs. 6, 7, 8 and 9 are fragmentary bot-tom plan views of various other modified forms of this invention.

Referring to. the drawings, -one embodiment of this invention comprises a circular disk record 1, made in any suitable way of any suitable material, but preferably made in a well known manner by compressing be.-

tween two heated matrices a well knowning the usual s iral sound groove 4, formed of lateral un ulations 'of uniform depth. Instead of the sound groove 4 described, any suitable sound record might be applied to the flat annular face 3 of the disk.

35 jecting rearwardly from the back 'of the 1 preferably substantially in the plane ofthe" The record is preferably provided with the a usual central aperture 5, and the centralpon' tion of the face of the record is preferably depressed within the recorded. surface 3, to form a shallow fiat circular recess 6, of substantially uniform depth and concentric with the record. .This recess 6 is adapted to receive the usual label 7 which is secured place in any suitable manner. The back or under side of the record is preferably provided wit-h a flat circular projection 8, form'- ing a part of the body :of-the record. The thickness of the projection 8 is. 'referably substantially uniform and su stantially equal to the depth of the labelre'cess 6, in the face of the record; and the diameter of the projection is preferably, however, as shown, slightly greater than'the diameter of the recess, to preserve a substantially uniform thickness throughout the body of the record. In other words, the label recess 6 is formed by depressing the central portion of the face of the record and correspondingly raising the central port-ion 8 of the back of the record a substantially equal amount. The

record is also provided upon its underside with a flat circular boss 9, surrounding and concentric with the central aperture 5 of the record, the diameter of the boss being only a smallflpart of the. diameter .of the projection, 8 of the back of the record, and being intended merely to strengthen the record around its central aperture.

The record is preferably formedwith an annular -marginal rib 10, preferably prorecord, the lower :surface of the rib being lower surface of the boss 9, at the center of the record. This annular marginal rib might be arranged to project 'forwardl fromthe front :of the record, if preferre Radial: ribs 11 are also provided upon the back of the record, the outer ends of these ribs being, spaced inwardly from the marginal rib, the inner portions of these radial ribs preferably overlapping. the circular projection 8, upon the backof the record, and

the inner ends of the ribs being preferably spaced from the boss 9, surroundingthe central aperture of the record. The under surfaces of the ribs 11 are preferably tangent to a plane coincident with the lower surface of the boss 9, and tangent to' the marginal rib 10, throughout substantially their fulllengths. The extremities of the ribs may be tapered to meet the under surface of the body of the record.

Instead of construetin the record with a marginal rib as hereto ore described, the

marginal rib may be omitted. as shown in:

Figs; 4 and 5,.thefrecord, being constructed in other respects identically as before or as hereinafter described. When the marginal rib is omitted, the record is obviouslymore ments of ribs.

and arranged. in; a

e of straight.

fragile, b ut may be found, when constructed offsuitable material, to be durable enough for ordinary purposes. 1

In Figs. 6, 7, 8 and9 are shown bottom tion, in which the body portion 2v of the record is constructed in eachinstance as v heretofore describedand shown in Figs. 1 to 5, but in which, theback of the record is provided with var'ious'forms and arrange- The under surfaces of all of the ribs in these modified forms are preferably tangent or coincident with the plane,

of the lower surface of the central boss 9.

The record shown in- Fig. 6 is provided on its back with a marginal rib .10 and with radial ribs 11, which maybecalled in this connection inner ribs, extending outwardly from the central projection ,8 and having their outer ends spaced fromthe marginal rib 10, as heretofore described, and also with comparatively short outer radial ribs 15 extending from the marginal rib 10 inwardly and having their inner ends spaced from the raised portion 8 of the back. In thisconstruction the -'outer ribs alternate with and overlap. the inner ribs, or, inother words, the alternate ribs are oppositely disposed staggered formation around't-he' record. The recordv shown in Fig. 7 is similar tov therecord shown inFig. 6, just described,

except that in the space between each two I adjacent outer radial ribs 15 are two inner radial ribs 11.

The record shown in Fig. 8 is similar to that shown in Fig; 7 and just described, except that in the space between each two adjacent inner radial ribs 11,are two outer radial ribs 15. Y

The record shown in. Fig. 9 is similar to the record shown-in Fig 6, heretofore'described, except that in this case the inner and outer ribs 11 and 15 are curved instead The ribs are shown curved. simply to indicate that ribs other than straight may housed, and the curved form shownis only one of many forms that'ob- ,viously might be employed and which might v be found to possess some advant-agesfor some purposes over the'stral'ght ribs; The invention, therefore, is not limited to any.

include all forms. 7

It is to be understood that in each of the various forms of records described above, all of the ribs, the projection 8, and the boss 9, arepreferably integral with the bodyofthe record, and that the record. as a whole, in-

tion might also be applied, however, to any particular form of rib, but is intended to record, whether compressed "-or not, and whether homogeneous or not; for instance, itmight be applied. to a cast or cutrecord or to a record having a layer of paper or cardboard embedded or inclosed in prefer mercial sound reproducing record is pro. duced which for any given material and for.

anygiven area of face or recorded surface has-a body portion of minimum thickness, and has consequently a minimum mass or bulk, butwhich is sufficiently rigid and durable for all. requirements.

Only a few of the many this invention may be embodied have been shown,.but these. forms are thought to be suflicientto illustrate the invention and to indicate that the invention is not limited to any particular construction described, but

might be applied in various forms without departing from the spirit of this invention or the scope of the appended claims.
