  The invention relates to a device for

  cut longitudinally through the middle of the bodies of slaughter animals. More particularly, the invention relates to a

  apparatus for cutting pig bodies longitudinally.

  At the time of their longitudinal cutting, these butcher bodies are generally suspended from hooks by their hind legs. In this position the butcher's bodies are split longitudinally along the entire length

  and cutting down. To do this you can use a chopper or saw. Cutting by hand with a chopper takes much more time and work than sawing with a circular saw or band saw. However the use

  a saw or even a chopper produced at the time of

  page a number of splinters or splinters scattered throughout

  meat and risk polluting it.

  On the other hand, it has been proposed to use a saw or chopper actuated by a hammer, but this type of cutting device does not give a clean cut.

  and does not split the skull.

  In addition the butcher's body must be split beyond the basin to allow the operation of this

type of cutting device.

  Most often the butcher's bodies are split longitudinally immediately after the slaughter, to allow the inspection of the spine, spinal cord and brains, in order to detect if necessary the

presence of abscess or others.

  To facilitate a proper and complete inspection, the cut must be as clean and clean as possible. Moreover, it is essential to avoid contaminating the joined parts by bone splinters, streaks of

spinal cord or others.

  The main purpose of the invention is to

  create a cutting device that can be used to cut

  finally the entire butcher's body, including the skull, making the cut through the middle of the spine. 2.The main purpose of the invention is also to produce a clean and clean cut without splinters or other

types of soil.

  Another object of the invention is to create a cutting device enabling the work to be suppressed.

  manual to be performed to split the butcher's bodies by hand.

  For this purpose the invention relates to a device for cutting butcher bodies, characterized in that it comprises a knife driven in a back and forth movement by a shelling device or the like, this shelling device being disposed at above one end of the knife, on the opposite side to a handle of the device

cutting.

  According to the invention the butcher body is cut longitudinally in two parts along the spine by means of a knife actuated by successive shocks, this knife being introduced on the ventral side and guided in two different ways: A: by means of a guiding device placed on the dorsal side of the butcher body to follow the spine, and a guiding device placed on the ventral side, these two devices supporting the butcher body on both sides of the spine; or B s by means of a needle-shaped guide member for insertion into the core of the

spine.

  In the initial phase of the cutting operation method A is used until the cutting has exceeded the basin curve, after which the method is used.

  B to split the butcher's body to beyond the shoulders.

  Finally, in the last part of the operation we take the

method A to split the skull.

  In cases where natural deformities of the spine pocket the use of the method Bq can be used method A to cut longitudinally the

whole butcher's body.

  The guiding device intended to be placed on the ventral side of the butcher body is mounted so as to be able to move laterally with respect to the column

  vertebral under the action of a pneumatic cylinder.

  3.- It is possible to regulate the air pressure in this cylinder so as to operate it as a spring or damping device. The guiding means intended to be placed along the back of the animal comprises at least one sliding pad or one or more casters pushed by springs to ensure precise guidance over the entire length of the spine. The needle-shaped guiding device is constituted by a fork with two teeth placed

  on both sides of the cutting knife.

  As a result, the bell runs between the two teeth of the fork. When the butcher body is slit beyond the pelvis curve, the needle guide device is pushed into the spinal cord by means of a pneumatic cylinder. In the area between the curve of the pelvis and the shoulders, the spine does not have a sudden curvature so that the guiding device in

  Needle shape can easily follow this spine.

  At the shoulders of the shoulders the spinal column presents a

  abrasion that prevents further movement of the needle-shaped guide device which is then removed to use the guide devices of method A. The contents are actuated by a ramming device mounted so as to rest upon the dorsal face of the butcher body when the cutting means are in operation. Due to the particular position of the pounding device a very short distance is obtained between the hammer and the point of impact of the knife. The speed of the ramming device and the operation of the cylinders are controlled by means of valves disposed on the handle. The cutting of the butcher's body is done by a movement towards the

  low with respect thereto, the cutting means being suspended

  removably due to support means. With a

  stroke of about 10 mm and 3,500 strokes per minute, we obtain a cutting speed of about 200 to 225 bodies of

pork on time.

  The invention will be better understood in

  reading of the detailed description that follows and which refers to

  an exemplary embodiment shown in the accompanying drawings, in which: FIG. 1 is a diagrammatic view, in elevation, of the cutting device according to the invention,

  FIG. 2 is a vertical sectional view

  FIG. 3 is a vertical sectional view along the line BB of FIG. 1; FIG. 4 is a schematic representation of the manner of guiding the cutting device along the column; FIG. vertebral means by means of the guiding devices according to the invention, and

  FIG. 5 represents a vertical section

  shim along the line C-C of Figure 1.

  In the figures, the reference 1 designates the cutting knife and the reference 2 is a device for

  comes or shelling intended to communicate with the knife a move-

  back and forth in the vertical direction by means of a

  transmission device 2a. Reference 3 designates a

  The guide is intended to engage the spinal column 4 on the back side of the animal so as to guide the knife on

  along this vertebral column 4 as shown in FIG.

  The reference 5 designates the hole of the spinal cord, the muscular part being designated by the reference 6. The means of

  guide 3 are suspended on a frame 7 guiding the knife 1.

  The shelling means 2 and the transmission means 2a are supported by the frame 7. The guiding device intended to be located on the ventral side of the butcher body is constituted, in the present embodiment shown in the accompanying figures. by two wheels 8 mounted on a common shaft 8a. These rollers 8 are intended to engage against the spine as shown in Figure 4. It will be noted that in an alternative embodiment, these wheels can be replaced by sliding pads. The wheels can be driven to

  front or rearward by a pneumatic cylinder 9 function-

  damper. The reference 10 designates the piston rod and the reference 11 the pivoting joint supporting the rotating knife. The speed of the pounding device can be controlled by means of a valve 12 mounted on the handle 13, while the guide means 8 can be controlled by means of a valve 14 mounted on a second handle 15. The pressure with which the guide means 8 abut against the spine can be adjusted by means of a control device comprising a pressure gauge, and at least one of the guide means comprises a damping device. Reference numeral 18 denotes a pneumatic cylinder moving the needle-shaped guiding device 19 up and down. The dotted lines in FIG. 5 show the needle-shaped guide means 19 in the low position. The opening of this needle-shaped guide device 19 is triggered by a valve

  mounted on the additional handle 15.

  As shown in Figure 6, the provision

  needle guide 19 guide the knife along the spine while other types of means of

  Classic stand maintain the butcher's body in place.

  The cutting device may be suspended by any type of conventional support means such as for example a pneumatic cylinder or an electrically driven load lifting pulley. The vertical movement of the cutapge device can be triggered by a pushbutton 16 mounted on the frame 7. This cutting device is suspended from a hook so as to be able to swing in equilibrium.

  The cutting device according to the invention

  It is small and easy to handle so that it can be used as a machine that can be maneuvered by hand. In an alternative embodiment, this cutting device can be suspended from a support and operate completely automatically, for example by means of photocells or devices.

with control valves.

  According to the invention the device of pestle-

  It should be located on the dorsal side of the butcher's body when the cutting device is in the operating position, the operator then being on the ventral side of the butcher's body. Because of the particular position of the shelling device, the power source is as close as possible to the cutting point, i.e. the spine. This position facilitates the operation of the cutting device by

  reducing wear and vibrations.

  6.- The cutting device is further equipped with movable guide means which can optionally be folded to thereby provide an apparatus whose control depends on the shape of the butcher body, the pelvis curve and the skull thereof. The number of comings and goings per minute should preferably be of the order of 600. The use of a greater number of comings and goings, up to 3,500 or more for example, allows the knife to perform movements very precise cutting

  giving an extremely clean and clean cut.
