ABSTRACT OF THE DISCLOSURE
A device for removing flesh from the body of a cod fish includes vacuum means for drawing the flesh from the body and means for severing the withdrawn flesh. The flesh can be tongue or other membraneous tissue.
Description
3~
Thi~s inyention relates to devices ~or e~iscerating portions o~ h and i~ p~rticular ~o a de~i~e ~or remo~ing ~lesh such as tongue or ~embraneous tissue from cod ~ish.
Conventionall~, a cod tongue or the flesh on the vertebrae known as '~cod sound~ is manually removed from each fis~ and the process ~s a slow and difficult one and is not without some danger to the operator doing the cutting. In the process o~ re~cving the tongue, ~or example, the operator uses one hand to grasp the gills and, in liting them, causes ~ -the tongue to protrude upward With the other hand, and using a straight ~lade knife, the operator cuts around the edge of the cod tongue, removes the other hand holding the ~ills and uses it to further lift the cod tongue now that it has been severed around both sides. The knife can then be inserted to cut the flesh holding the forward and rear-ward part of the ~ongue for its complete removal.
The present ~nvention is adapted to overcome t~e disadvantages of the manual method mentioned above and to substantiall~ speed-up the process of removal of cod tongue.
2a The only skill required in using the apparatus of the present invention is for an operator to place a cod head into a specific position on a supporting plate where~y the tongue of the fish is mechanically moved.
Using a hand knife for cutting out cod tongues is dangerous, particularly for those not s~illed in the art.
The apparatus of the present invention el;mina-tes the hand cutting and, ~ecause of the ease of placing the cod head in position for the mechanical cut, the process can ~e performed by the non-skilled while at the same time increas;ng production 3a substantially.
The apparatus o~ the present in~rention will also cut the flesh from the vertabrae~ thi`s ~lesh ~-eing known in the trade as "cod s-ound~ When cod fish are cured ~or the salting process, the vertahrae or sound ~one ~s removed~
This ~s done ~y hand us-ing a curved ~lade ~nife or hy mechanical means known as a splitting machine, The flesh on one side o~ the ~one is a saleable product ~ut the production is ver~ limited because of the traditional method of cutting o~f the flesh ~y hand. The same method of removing the tongue from the cod head can be used in removing the flesh from the vertabrae as explained hereinafter.
According to a broad aspect, the invention relates to apparatus for removing selected flesh from cod fish com-prising vacuum means for drawing the flesh from the fish, cutting means for severing the flesh from the fish and means for removing the flesh from the cutting area.
T~e vacuum means includes an apertured plate for receiving the flesh therethrough, a storage tank for receiving cut flesh, vacuum being applied to the tank; and a conduit interconnecting the aperture in the tank.
The i`nvention is illustrated ~y way of example in the acco~par.ying drawings in which:
Figure 1 is a perspective view of the underside of the head of the cod fish;
Figure 2 is an elevation view, partly sectioned away, of the apparatus o~ the present invention, Figure 3 i-s a plan view-of part of the assem~ly shown in Figure 2, and --~2 ~3~i7~L
Figu~e 4 îs a partial plan ~iew of one part o~ the apparatus~
~ eXer.~;ng to ~i~ure 1, a cod fish head 10 is illustrated show~ng t-~e ~i~lls 12 and the location of the ton~ue 14. The apparatus for removing t~e ~ongue is shown in Figure 2 and compri~ses a tank 16 having :liquid 18 thereinr vacuum ~eing applied ~o the upper part of tlle tank ~y any suitable vacuum means, not shown. A conduit or hose 20 interconnects the tank with an aperture 22 ;n a supporting plate 24, this aperture ~eing sufficientlY large and of a configuration suitable to receive the tongue of the cod.
It will be observed from Figure 2 that when the cod head is placed tongue down over the aper~ure 22 the vacuum in the condui~ 20 ~ill draw the tongue from the head and down into the aperture as seen in Figure 20 The means for severing the tongue 14 from the cod head 10 consists of a rotary knife 26 mounted on and rotated by suitable motor me~ns 28 which in turn is positioned for reciprocatiOn on a supporting track 30. Means for reciprocating the motor 28 and knife 26 is in the form of a suitable rotating device such as a motor 32 and crank 34 connecting motor 32 with the supporting track 30. The rotating means 32 can be indexed for causing reciprocation during specific time periods or ~t can be a one time actuation operated ~y the operator's ~oot etc~ Experimentall~, the apparatus has been running with.~ reciprocation rate of a~out two and a half seconds per cycle~
~t ~ill he observed that the cutting blade 26~
when reciprocated, will be moved forward and back~ard b~ the rotary means 32, the blade 26 moving o~er the top of the plate i7~
24 between the cod tongue 14 and ~he cod head ln, the position o~ the cuttin~ means i.n the ~orward, cuttin~ position being shown b~ the das~ed line 36. Thi`~operation se~ers the tongue from the cod head, the tongue 14 being drawn by ~acuum into t~e tank 18 while the cod head 10 can be dis~
carded over the top of the blade.
Fi~ure 4 is a fragmentary vie~ of a plate 124 having an aperture 122 therëin. It will be observed that the aperture 122 is somewhat diffexent in configuration than aperture 22 in plate 24, aperture 122 being so shaped as to receive the vertabrae of the Eish so that the flesh portion or cod sound is drawn down into the aperture 122 and removed by the cutting means in the same manner as that used to remove the tongue from the cod head.
It will be appreciated that the form of cutting means shown is by wa~ of example only and that various other types of knives and means of operating them can be used without departing from the scope of this invention.
T~e terms and expressions which have been employed in this specification are used as terms of description and not of limitation, and there is no intention in the use o such terms and expressions to exclude any equivalents of the features shown and described or portions thereof, but it is recognized that vari~ous modifications are possible within the scope of the in~ention claimed.
