16 Claims.
This invention relates to certain new and useful improvements in spliced film.
In the use of film it is very often necessary to splice the film or secure two longitudinal sections together, and in connection with moving picture film this condition produces no ill affeet, but when a narrow sound track is provided at one edge of the picture framing for the reception of a photographic record of light waves varied in accordance with sound waves, 2. splice across the sound track portion produces a click or undesirable noise when the sound record is reproduced in the usual manner.
The main object of this invention is the production of a splice in a combined moving picture and sound record film by means of which the click resultant 'from the usual splice is eliminated.
Other objects and advantages relate to the details of the spliced film, all as will more fully appear from the following description taken in connection with the accompanying drawing, in which:
Figure l is a plan view of a section of a spliced film of this invention.
Figure 2 is an enlarged section on line 2-2, Figure 1.
Figure 3 is an enlarged section on line 3-3, Figure 1.
The film as shown in Figure 1 comprises a moving picture portion 1, the sections of which when the pictures have been taken thereon may have the usual framing indicated.
At one edge of this framing there is provided the usual sprocket hole section 2. Bordering the other edge of the picture section I is a narrow sound track 3 indicated as having a sound record produced thereon and at the outer edge of the sound track '3 there is the usual sprocket 40 hole section 4.
In the splicing of moving picture film it has been common to provide a splice extending across the film at right angles to the length of the film, but as above stated, when such a splice extends across a sound track a click re: sults when the record is reproduced by the usual reproducing devices.
This invention eliminates or substantially eliminates the production of such undesirable noises in reproduction and for that purpose the ,splice may be formed as illustrated in Figure 1.
The adjacent edges of the two sections of film indicated at 5 and 6 are of complementary form. The edge of both sections may be cut or formed along straight lines indicated at I (Cl. 274-4l.6)
-- and 3 respectively, which are perpendicular to the length of the film or to a longitudinal edge of the film. When the sound track is reached,
the section 5 is cut diagonally from the terminaformed with a complementary edge, i. e. it may be cut across the picture portion l and the sprocket hole portion 2 along a straight line I perpendicular to the edge of the film. The sound track 3 is then cut diagonally on line H parallel with line 9, but extending rearwardly into the body of the film rather than forming a projection from the film to provide a cut-away portion of the sound track in the section 8 complementary to the extension of the sound track formed on the section 5.
The sprocket hole strip 4 on section 6 may then be cut straight across as on line l2 parallel with line 8. The so formed edges of film sections 5 and 5 are preferably beveled, as indicated in Figure 2, and Figure 3, and the beveled sec- 0 tions are placed in overlying relation and secured together by any suitable adhesive or otherwise, as may be desirable.
It will be apparent that'with this construction the splice extends straight across the picture section on a line perpendicular with the longitudinal edge of the film, and that the 'splice extends diagonally across the sound track portion preferably on an angle of substantially 45 degrees or less with a line drawn lengthwise of the inner edge of the sound track. The splice may then extend along straight lines laterally to the edge of the film across the sprocket hole section 4 on a line parallel with the splice across the picture section I but displaced thereirom lengthwise of the film.
It is found that with a splice of this form the usual click resultant from a lateral splice in a sound record is eliminated or substantially eliminated, and no interruption or undesirable noise occurs when the spliced portion of the sound track passes the usual reproducing line of light.
Altho I have shown and described a specific form of splice and specific shapes of the complementary edges of the film sections at the splice,
I do not desire to restrict myself to the exact form shown, as various changes and modifications may be made within the scope of the appended claims.
I claim:
