BACKGROUND OF THE INVENTION

BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates to phonograph records and more particularly to methods for making phonograph records.
2. Prior Art In the pxior art, phonograph records have been generall~
made from an opaque material. In recent years, it has become desirable to place pictures directly on the phonograph record.
The initial attempts were only small pictures and were printed on a paper label which was affixed to the record by an adhesive in the central area where there are no grooves present. Since this is a very limited area, such a process is undesirable.
Since it is desirable to have a largar picture axea and the picture itself cannot be affixed to the entire exterior of the record because the paper or other material fxom which the ;~ picture is printed on will cover the sound grooves, it has been proposed that the picture be placed in the interior of the record and the record be made from a transparent matexial. To accomplish 2~ this feat, it has been proposed that the record be made into two hal~es and that the two halves be then bonded together with the picture in between~ Such a process is undesirable because it requires two pressings, it is more expensive and the record may delaminate with age.
SUMMARY OF THE INVENTION
Accordingly, it is a general object of the present invention to provide a process for making a transparent record having a picture therein which is simple and low in cost.

In keeping with the principles of the present invention, the objects axe accomplished by a process for making a plastic record which includes the ordered steps of placing a cake of transparent moldable plas~ic in a record press having grooves fox impressing sound grooves into the plastic, placing an ~ opaque sheet of materlal having a pictuxe printed thereon on .; at least one side on the cake in the record press, placiny a transparent moldable plastic on top of the opaque sheet o~ material and pressing the combined cake sheet and transparent plastic in the record press whereby a transparent record having a picture and sound grooves contained therein is formed.
BRIEF DESCRIP'rION OF THE DRAWINGS
The above-mentioned features and objects of the present invention will become more apparent with reference .to the following description taken in conjunction with the accompanying drawings wherein like reference numerals denote like elements and in which:
FIGURE 1 is a cross sectional view illustrating one 2~
- step of a first embodiment of a process for making a plastic record in accordance with the teachings of the present invention;
FIGURE 2 is a cross sectional view illustrating a second step of a process for making a plastic record in accordance with the teachings of the present invention;
FIGURE 3 is a top plane view illustrating a result product made by means of a process for making a plastic record in accordance with the teachings of the present invention; and FIGURE 4 is a cross sectional view illustrating a : 30 : second embodiment of a process for making a plastlc xecord in 3~%
1 accordance with the teachings of the present invention~
DETAII,ED DESCRIPTION OF THE I~ IENTION
Referring more particularly to the drawings, shown in Figures l and 2 is a process for making plastic records in accordance with the teachings of the present invention. In Figure l is shown a movable mold from a moldin~ press which includes a.n upper half 2 and a lower half 4. Contained in both the upper half 2 and the lower half 4 is a pattern for a record which includes the sound grooves and is for khe purpose of forming a record from a moldable plastic.
A cake 6 is placed between the upper half 2 and lower half 4 of the movable mold. ThP cake 6 is a transparent moldable plastic such as polyvinyl. Onto the cake 6 is placed an opaque sheet 8 which includes a picture printed on at least one side thereof. In some instances ~ picture may be provided on both sides of the sheet 8. A sheet lO of transparent plastic is then placed on top of the sheet 8.
~At this point, the record is ready for pressing. As :: indicated by the arrows in Figure I, the upper mold half 2 is . 20 :~pressed against the lower half mold 4. The cake 6 spreads out to fill the mold and the sound grooves.provided in the upper and lower halves 2 and 4 are pressed into the exterior surEaces of the cake 6 and the transparent moldable plastic sheet lO.
In addition, the transparent moldable.plastic sheet lO is fused to the cake 6 by the heat and compressive forces within the record press mold as shown in Figure 2.
The upper half 2 is then moved away from the lower half 4 and the completed record 12 with picture 14 as shown in Figure 3 is removed from the record press.
' 3~ .
1 Referri~g to Fi~ure 4, shown therein is a second embodiment of a process Eor making a plastic record in accordance with the -teachings of the present invention. In Figure 4, a cake 6 for transparent moldable plastic is again placed in the record press mold and a sheet having a picture printed thereon is placed on top of the cake ~. Then a cake 16 of transparent moldahle plastic is placed on top of the sheet 8. This time the upper half mold 2 is pressed against the lower half 4 as indicated by the arrows and the result in product is substantially the same as is illustrated in Figures 2 and 3.
It should be apparent from the above description, that the process of the presen-k inventlon produces a record having a picture therein and the process is simple and inexpensive~
It should be appaxent to one skilled in the art that the above described embodiment is merely illustrative of but a few of the many possible specific embodiments which represent the application of the principles o the present invention.
Numerous and varied other arrangements can be readily devised by those skilled in the art without departing from the spirit and scope of the invention.
