Dec. 29, 1942. c. c. HASIN PHONOGRAPH RECORD Filed Sept. 28, 1940 Isnugntor Charles 6'. Hafiz/n 83 g 2 I (Ittorneg Patented Dec. 2 9, 1942 UNITED STATES PATENT f-',0FFICE @ZZZZTSLTZZZZZZTL. Application September as, 1940, Serial No. 358,770 8Claims. (on. 2-14-42) In the aforesaid copending application, I have shown a flexible record suitably interlocked with a base layer which serves as a supporting base therefor and provided with a cover which may.
constitute an extension of the base, the record itself being removably associated with the base. Under certain circumstances, it is preferable to secure the record to the base so that it cannot come loose therefrom. Heretofore, it has been known to secure a flexible record to a suitable base, as by an adhesive, butthe adhesive has been applied over the entire area of the record. If moisture should happen to enter between the record and the base, the adhesive becomes clouded or discolored, and this presents an unsightly appearance when the record is made of transparent material.
Records of the type under consideration have been proposed for use in connection with personal messages, birthday greetings, advertising matter, and the like, and are usually suitable for mailing because of the flexible character thereof. When manufactured under certain climatic conditions and mailed to another part of the world where the climatic conditions are greatly different, it is not unusual for such records to become somewhat altered in size and for the grooved layer thereof to become separated from the base layer by reason of the fact that the two materials thereof have different coefficients of expansion and different warping characteristics.
The primary object of my present invention is to provide an improvedphonograph record and package or cover therefor which will be free from the aforement oned disadvantages.
for as aforesaid which is simple in construction and which may be easily manufactured in great quantities and at small cost.
In accordance with my present invention, I provide a sheet of base material on one-half of which the sound grooves are formed, and I secure the latter sheet to the base preferably by means of an adhesive and'only in aregion along the marginal portion of the grooved sheet and for a distance inwardly short of the area occupied by the sound groove thereon. Thus, only the peripheral portion of the grooved sheet or disc is bonded to the base, the central portion thereof being free to bend or twist relative to the base, asduring handling, changes in temperature, and under similar other conditions. Obviously, since there is no adhesive between the grooved d sc or sheet and the base sheet, under the .area occupied by the grooves, if moisture should enter between the two sheets, there will be no discoloration to mar the appearance of the record. After the grooved disc is secured in place on the base, the other half of the base sheet is folded over onto the first-mentioned half thereof and over the grooved disc to cover the latter, the two halves of the base sheet being secured at the marginal portions thereof. The central portion of the cover part is preferably perforated to provide a removable disc superposed over the sound grooves, and, to facilitate removal of this disc, I preferably provide a slot or the like therein which afiords a tab that may be grasped by the fingers, thus affording a firm hold on the disc as it is being torn along the aforementioned perforation. Once this disc in the cover is removed, the groove .in
the record sheet becomes exposed for playing.
The novel features-that I consider character-' from the following description of one embodi-- ment thereof, when read in connection with the accompanying drawing, in which,
Figure 1 is a plan view of a record and package formed according to my present invention and showing the base sheet unfolded with the cover portion thereof to one side of the grooved sheet,
Figure 2 is a view thereof with the cover folded over and the record and package in fully assembled relation, and
Figure 3 is a sectional view taken on the line IIIIII of Figure 2 and greatly exaggerated as to thickness for the sake of clearness.
Referring more particularly to the drawing, there is shown a sheet l of suitable material,
, such as cardboard, or of any other preferably inexpensive fibrous backing material, one half: la
I mount a suitable transparent sheet on which 55 of which constitutes the base proper and the other half lb of which constitutes a cover when the record is assembled as shown in Figure 2, a score line or the like 2 being provided substantially across the center of the sheet I to permit easy bending of the part lb relative to the part la. Secured to the base part la by means of a suitable adhesive 3 is'a sheet 5, preferably of a transparent material, such as cellulose acetate or the like, on which is formed a spiral sound groove 1 in well-known manner, the adhesive 3 being applied only' to the marginalaportion of the sheet and extending radially inwardly thereon a distance short of the area occupied by the groove 1. The base part la and the sheet 5 are provided with aligned openings .9 which are coaxial with the spiral groove 1 and which are adapted to receive the spindle of a turntable in conventional manner. a
Preferably. although not grooved sheet 5 is of smaller dimension than the base part la and, when mounted centrallyon the base part la, a marginal portion ll remains exposed on the base part la. After the grooved record sheet 5 has been'secured to the base part la, the cover part lb is folded on the score line 2 over onto the base part la to cover the grooved sheet 5, and the cover part lb is preferably se cured to the base part la along the upper, the lower, and the left-hand marginal portions II, as viewed in Figure 1, by means of an adhesive l3 which may be the same as the adhesive 3. Thus, there is provided a unitary three-layer structure with the grooved sheet 5 sandwiched in between the parts In and lb and in which the record groove 1 is protected against injury during handling and in transit.
The cover part lb is formed with a circular perforation l5 to provide a central disc I! which may be removed from the cover part lb b tearing along the perforation l5. To facilitate taking hold of the disc H, a sl t or slot l9 may be formed on the disc l1 to extend substantially radially inwardly from the perforation l5, 'thus providing a tab 2| which can easily be grasped between the thumb and forefinger. The perforation I5 is preferably concentric with the groove 1 and of a slightly larger diameter, so that when the disc I1. is removed, the groove 1 will become entirely exposed for play ng.
It will be obvious, from the foregoing 'description, that I have provided a novel and simple laminated record which can be sent safely through the ma ils without danger of injury and which can be quickly prepared for playing by simply tearing out the center disc II. It will also be obvious that my improved record lends itself well to advertsing since,after the disc I! has been torn from the cover part lb, four surfaces become necessarily, the
available for advertising matter, namely, the back of the base part I a, the surface thereof under the transparent rec rd disc 5. and both surfaces of the disc l By applying the adhesive 3 only to the marginal p rtions of the record sheet 5, the surface under the sheet 5 not only will not become clouded when moisture enters in between the l yers la and 5, but it isobvious that the central port ons of the sheets la and 5 are free to move or twist or bend relative to each other sli ht v, so that changes in temperature will not deleteriously affect the size or shape of the groove 1.
Although I have shown and described but one embodi ent of my present invention, it will be obvio s that many other modifications thereof. as well as changes in the particular modifications therefore. desire that my invention shall not be limited except insofar as is made necessary by the prior art and by the spirit of the appended claims.
