Walsh, West Hempstead, and John Anto?lli, Astoria, N. Y. Application March 6, 1936, Serial No. 67,436 17 Claims. ~ The present invention relates to an improve ment in apparatus for making and applying so called bloop eliminators on mended or spliced sound-on-?lm moving picture positive ?lm. Where positive ?lm having a sound track has been spliced in the usual way, usually with a loss of sound sequence, the passage of the positive _?lm past the sound reproducing means with the 11,9 spliced section will cause the reproducer to create a sound known as a bloop, when the patched part passes the reproducer. It has been found that if a triangular blanking of the patched sound track section is effected, to mask the interrupted section of the sound track completely out by a gradual increase and de crease of the masking blank, in contour, the spliced sound track passes the sound reproducer substantially without blooping. One outstanding feature of the present im provement is in the manner of applying the bloop eliminator, its present form being in the form of a patch, or cut out light-proof, mask, being cut from a strip of gummed, opaque material of ?exible nature, and applied directly, after the cutting thereof, to the spliced sound-wave track, by the means which cut the bloop patch from the strip. A further feature of novelty and advantage is .30 in the rolled strip of bloop patch material. Another advantage is in the provision of means for holding the spliced ?lm and its inter rupted sound track in registering relation with the bloop patch strip, so that the cutting out “ of the bloop patch and its instant application to the spliced sound track portion of the ?lm is quickly and accurately accomplished. I-Ieretofore, bloop eliminators have been stamped or printed upon the sound track with an 40 opaque ink. The foregoing and other features of advantage will be apprehended as the herein description pro ceeds and it is obvious that modi?cations may be made in the methods and apparatus disclosed herein without departing from the spirit hereof or the scope of the appended claims. Fig. 4 is a transverse section taken across the cutting punch, at 4-4, Fig. 1, looking in the di rection of the arrows; Fig. 5 is a fragmentary length of the bloop Fig. 6 is a fragmented view of a spliced sound on-film positive, illustrating the spliced sound 10 track with a bloop patch covering the interrupted sound sequence track. The blooppatch' cutter and applier generally denoted by I, Fig. 1, is substantially in the form of a hand operated punch, having a base 2, a 15 table 3, supported by integral webs 4-4 between the base and the overhanging horizontal table. An integral, upstanding rear wall, of suitable ‘contour, Fig. 1, is arranged to support an opera tive bloop patch feeding cutting and applying means. To this end the rear Wall 5, which con stitutes, with the base 2 and table 3, the frame of the device, is provided with a bloop patch strip feed opening 1, Figs, 1 and 2 through which is fed, from a roll- 50, at the rear of Fig. 2, a com position in said gibway by opposed gib-plates Ill-Ill, which in turn are ?xedly held to said gib way 6 by fastenings such as ?llister head screws 35 I l_l I, Fig. 1. > At the top of the plunger slide, Figs. 1-2 is located a hand plunger generally denoted by l2, Figs. 1 and 2. This plunger may be otherwise constructed, but as shown, it comprises an angled lower portion I3, seated upon one side and the upper edge of plunger 9, and held thereto by screws such as I 4. When this hand plunger is struck, it is forced down to about the dotted po sition X, Fig, 2. _ The lower end of the slide 9 is recessed to op eratively receive therein a male cutting die 16, Fig. 2 is a vertical sectional view of the device itself being bounded at its three other edges by tion of the arrow; Fig, 3 is a transverse sectional View taken -on the recess in slide 9, as indicated in Fig. 1. line 3-3, Fig. 2 looking in the direction of the 55 arrow; 25 bined bloop patch strip C and its conveyor strip generally denoted by 50, Fig. 5, to be described in detail later. Above the opening ‘I is located a gibway 6, Figs. 2 and 3, which slidably mounts therein a 30 plunger slide 9, the slide being held in operative taken on the line 2—2, Fig. 1, looking in the direc_ Fig. 1 is a front elevation of a bloop patch cut ting and patch applying device; i) patch strip, with a portion of the bloop patch ma terial lifted to show the structure of the patch material conveyor strip; and the lower end D of which is of the same outline as the bloop patch B, Fig. 6, and as indicated by its section, shown at DIG, Fig. 4. This die is re movably held to slide 9 by a screw ll, the die In the drawing, I 50 (Cl. 216—28) The front face of the wall frame 5 is provided with two lugs 45-45 adjacent the lower cutting edge D of the die I6 and located upon said lugs is 2 2,135,684 a stripper 42 which has an opening 43 therein, Fig. 2 and in which the lower cutting edge D of strip of Fig. 5. Springs 3] press the ?ngers downwardly, constantly. The ratchet ends 33 of the die normally rests. The stripper 42 is held ?ngers 30 ride in the slots 33, was to engage in the feed slots T—T of the bloop strip, with a on said lugs 45—45 by screws 44—44. Immediately below the stripper is located a female die 39, in register with the male cutting die D, and into which said die D enters upon the operation thereof to punch out a bloop patch. Die 39 is located upon an extension 36 of the roll holding frame 35, Fig. 2, by its ?ange E, and positive action. The feed arm 24 at about its mid-section is provided with an adjusted screw 29, located in an arm lug 29’ the front end of the screw rest ing, when the arm 24 isin its full forward posi tion, upon the rear face of the wall frame por 10 tion 6. The purpose of this is to cause precise is secured to the rear face of frame 5 by suitable screws, not shown. Extension 36 passes through registration of the cutting portion of the bloop aperture 1. strip under the die D, on each forward feed stroke The slide 9, at its rear, Fig.‘ 2, has an extend 15 ing pin !8, which is integral with a slotted threaded end H, to be adjustable and withdraw~ able from the front of the slide with a screw driver. The pin end I8 extends outwardly into an aligned slotted blind bore 20 located in the 20 rear of the slide in portion 6 of frame 5. The blind bore- 20 supports a coiled spring l9 therein on the top of which is a centering plunger 2|, upon which rests the extended slide pin end l8, and thus the spring l9 tends to keep the plunger slide die assembly in its upper position as shown in Figs. 1 and 2, and to return ‘said assembly, after each bloop punching. operation. A ver tical slot 52 in the portion 6 gives'clearance for 'reciprocal movement of the extended pin end l8. At the upper end of'the plunger slide 9, and adjacent thereto in portion 5, are located alined, slots 23’ and [5, Fig. 2, respectively. Into these slots is projected a bell crank extension 5| of a feed arm 24, which is pivoted on a pin 26, said pin being supported between two supporting lugs 26, only one of which is shown in Fig. 2, but fully disclosed in Fig. 3. These lugs are integral with portion 6 of wall frame 5. V The bell crank extension. 5|, Fig. 2, has a of arm 24. Below the female die extension 36, Fig. 2, and 15 upon table 3, is located a ?nished, ?at, prefer ably rectangular platen 40, this being held in op erative position by screws 4I-4l to table 3. This platen is provided with spaced apart regis tering pins 38-—-38, properly located to permit the registering thereon of a ?lm F to be operated ‘upon, by its sprocket feed holes M adjacent the sound track S, these latter elements being shown in Fig. 6. When a spliced ?lm F is properly lo cated upon the pins 38 with the spliced portion P located under the longitudinal center of the patch cutting die and at right angles to the di rection of feed of the bloop patch strip 50, a stroke on plunger |2,‘cuts a patch B‘ from the. strip, pushes‘ it down through female die 39, and deposits it upon the spliced ?lm, on the sound track S, as at B, Fig. 6. As the patch has its under face coated with an adherent, the patch is permanently af?xed to the ?lm in proper bloop eliminating position, as in Fig". 6, wherein the‘ widest transverse section of the patch completely blocks that part of the sound track at the spliced part of the film, and gradually tapers to a sharp point on either side ‘of the splice masking por rounded cam end 21 which rides on the under tion. face at the upper end of slot 15, during recip rocal movement of slide 9. At the mid-portion one being the feed strip N, preferably of thin of the bell ‘crank extension, and on the under face thereof is located an extending lug 28', which engages into the upper end of a coiled spring 23 the lower end of which is mounted upon a cen~ tering plunger 22, which in turn rests upon ex tending pin end l8 of the slide 9.’ The bloop strip 50, Fig. 5, comprises two strips, ‘tough paper, and having marginal feeding slots ‘T—T along both edges, to permit of step by step feeding by the feed arm 24, and being also pro 45 vided with cut-out slots 0, which are located between the feed slots T—T. The patch strip material C may be of any suit As described, an operative-blow upon hand plunger 42, causes die D to cut a bloop patch and throws the feed arm 24 back to the dotted position able cellulosic base, opaque, and preferably black, X’, Fig. 2, thus to engage the bloop strip 50, to strip C is adhered to the paper feed strip N with its coated face against the face of the feed strip, thus unifying the two strips into a single strip, feed a fresh portion of the strip from the roll 50' to the die position. This is accomplished as follows: the roll holding extension or frame 35 as positioned in Fig. 2 has a pair of upstand ing yoke 4"! arms 46, only one of which isshown, and in these yoke arms is removably located a shaft 48 which rotatably supports a roll of bloop strip 50’ and its core 54. The frame 35 is provided on opposite sides with two spaced and ?anged bloop strip guides, only one of which, 49, is shown in Fig. 2. The frame 35 is also provided with two spaced - grooves, only one of which is shown in Fig. 2. These grooves are spaced apart so as to register and is treated on one face with a suitable ad herent of, preferably, non-drying nature. This 60 after which it is rolled, for use in the device of 55 Figs. 1 and 2. The feed strip performs the function of per mitting the bloop strip» to be rolled, without stick ing and to be easily unrolled and handled, be cause of the use of a non-drying gum. The openings’ 0 permit the blanking there through of a bloop patch as required, and as shown at B, Fig. 5, where two bloop patches have been blanked therefrom. 65 In use the bloop strip is mounted in the ma with the feed perforations T—T in the mar chine with the paper N underneath, and the ' gins A of the bloop strip 50',’ Fig. 5. bloop patch strip C' on top, so that the adherent coated face of the bloop patch strip faces the spliced ?lm F, when in position. Then as the 70 ?lm Fis located in the machine upon pins 38—38, the bloop strip 5, is fed across said ?lm F, and at' right angles thereto, and as the die D cuts and pushes down the bloop patch B upon the The arm 24, at its lower end '32, is curved out wardly and pivotally supports two spring actu ated bloop strip feeder ?ngers 30, only one of which is shown in Fig. 2. These ?ngers are du plicate, have stops to limit their downward movement and are spaced apart so as to register with and engage the feed slots T—'T of the bloop ?lm 'F, it also drives the bloop patch B against 75 3 2,135,684 said ?lm and the patch thus ?rmly and accurate ly mounted upon the spliced sound track. In the patch material strip, as in Fig. 5, the elongate patch perforations 0 between the mar ginal feed slots T on the conveyor strip 50, are so spaced as to bound, by their edges, the limits of the patch material and exposed adherent face from which the bloop patch is cut, and as so constructed the area of the patch material left '10 exposed in the perforations is prevented from sticking when the strip is rolled for shipping and feeding. Due to the structure of the slide 9 and its spring l9, and the spring control of the lever arm 24 and its spring 23 both of these members while operative substantially simultaneously they movable downwardly through the strip and said opening. 5.
