APPARATUS FOR ELIMINATING BLOOPS IN
SPLICED‘ SO-UND-ON-FILM MOVING PIC
TUBE POSITIVE FILMS
Thomas J. 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.

cutting punch, at 4-4, Fig. 1, looking in the di
rection of the arrows;

Fig. 6 is a fragmented view of a spliced sound

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

> 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

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

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

face at the upper end of slot 15, during recip

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

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

The feed strip performs the function of per

cause of the use of a non-drying gum.
The openings’ 0 permit the blanking there

been blanked therefrom.

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.

spring l9, and the spring control of the lever

opening.
