The system includes a track that extends horizontally over the pens and is suspended from the ceiling structure. A carriage assembly is mounted on the track for travel along the track. Rotatably secured to the carriage assembly about a vertical axis is a winch apparatus that extends downwardly from the carriage. Secured to the winch is a flexible means that moves vertically with respect to the winch which is attached to dead animals for raising the animal above the pen and lowering the animal to the dead animal depository.
Description




BACKGROUND OF THE INVENTION




This invention is directed toward an apparatus for lifting and transporting dead animals and more particularly an apparatus for removing a carcass in a hog confinement building.




Removing an animal carcass from a building presents many problems. Because of the size and weight of some animals, manually removing the carcass is difficult if not impossible. Further, because of the long and narrow structure of many hog confinement buildings it is difficult to maneuver a transporting device into the pen for removal of the carcass. Also, other live animals in the pen may interfere and need to be removed prior to removing the carcass with the transporting device. Therefore, a need exists for a simple system to transport a carcass to a depository station that is capable of lifting heavy animals without interfering with other animals in the pen.




Thus an objective of the invention is to provide an apparatus for removing a carcass that is simple to manufacture and simple to operate.




Another objective of the invention is to provide an apparatus for removing a carcass that is capable of lifting and moving heavy animals.




BRIEF SUMMARY OF THE INVENTION




The invention is a system for removing dead animals from a building having a ceiling structure, a plurality of parallel elongated pens, and a dead animal depository station. The system includes a track that extends horizontally over the pens and is suspended from the ceiling structure. A carriage assembly is mounted on the track for travel along the track. Rotatably secured to the carriage assembly about a vertical axis is a winch apparatus that extends downwardly from the carriage. Secured to the winch is a flexible means that moves vertically with respect to the winch which is attached to dead animals for raising the animal above the pen and lowering the animal to the dead animal depository.

DETAILED DESCRIPTION OF THE INVENTION




Referring to the drawings, the system of the invention is referred to generally by reference numeral


10


. While this description refers to the removal of hogs from a confinement building, the system


10


can be used in any type of building for removing any type of animal. In this example, as shown in

FIG. 1

, the system


10


is used in a confinement building


1


having a ceiling structure


2


, a plurality of parallel elongated pens


3


, and a dead animal depository station (not shown). The depository station can be an area of building


1


that is cleared for temporary storage of the carcass, an empty pen, or a vehicle for transporting the carcass to another location.




The system


10


for removing dead animals includes an elongated overhead horizontal track


12


that is suspended from the ceiling structure


2


and extends in a transverse direction over the pen


3


. As shown in

FIGS. 2 and 3

, the track


12


is a single C-shaped member with ends


13


that extend vertically.

FIGS. 4 and 5

show an alternative embodiment where the track has three horizontal members that are suspended from the ceiling structure. In this embodiment the track


12


A is cylindrical in shape. The track is suspended from the ceiling by vertical members


14


connected to the ceiling structure


2


.




With reference to

FIGS. 2 and 3

, moveably mounted on the track


12


is a carriage


16


for travel along the track


12


. The carriage


16


has a pair of side members


18


(

FIG. 2

) that extend downwardly from the track


12


and are connected by a plate


20


that extends between the side members


18


. The plate


20


has a plurality of holes


22


(

FIG. 3

) that extend through the plate


20


and are positioned radially around the center of the plate. A pair of wheels


24


with outwardly extending axles


26


are connected to the side members


18


. The wheels, as shown in

FIGS. 2 and 3

are fitted on the track


12


for movement thereon. In an alternative embodiment, shown in

FIGS. 4 and 5

, four pairs of wheels


24


have axles


26


that extend between each of the pair of wheels. Two sets of wheels


24


are positioned in spaced relation on the same horizontal track members and the other two sets of wheels


24


are positioned in spaced relation on the other horizontal track members. The side members


14


are connected to the axles


26


of the respective sets of wheels


24


for movement on the tracks


12


A.




Rotatably secured to the carriage assembly


16


about a vertical axis is a winch apparatus


28


(FIGS.


2


and


3


). The winch extends downwardly from the carriage assembly


16


and includes a rotatable crank shaft


30


and handle


32


. The crank shaft


30


is enclosed in a housing


34


having a top


36


, sides


38


, ends


40


, and a bottom


42


. The winch can be manually or electrically operated by a power source (not shown). A rotatable swivel


44


extends from the carriage assembly


16


to the winch apparatus


28


and allows the winch apparatus


28


to rotate in relation to the carriage assembly


16


about a vertical axis on bearings (not shown). A spring loaded pin


46


extends upwardly from the top


36


of the winch


28


for movement in and out of the holes


22


of the carriage plate


20


. The spring loaded pin


46


locks the winch


28


in a position in relation to the carriage assembly. The ability to rotate the winch


28


in relation to the carriage assembly


16


and lock the winch


28


in position with the pin


46


allows for positioning the optimum angles for use.




Secured to the winch is a cable


48


with a loop


50


on one end. The cable


48


, which extends through an opening in the bottom


42


of the winch


28


can be retracted and wrapped around the crank shaft


30


when the handle


32


is rotated. The cable


48


is released and extended through an opening in the bottom


42


when the handle is rotated in the opposite direction. The loop


50


on the end of the cable


48


is for attaching the cable to the dead animal


52


for removal.




In use, the carriage assembly


16


is moved on the track


12


to a position near the animal


52


. The pin


46


is retracted out of one of the holes


22


of the plate


20


and the winch


28


is rotated about the swivel


44


such that the cable


48


will extend is substantially a straight line toward the animal


52


. When the winch


28


is positioned at an optimum angle the pin


46


is released into one of the holes


22


of the plate


20


locking the winch


28


into position in relation to the carriage assembly


16


. Once in position, the handle


32


is rotated in a direction releasing the cable


48


from the crank shaft


30


. Once the cable


48


has reached the animal


52


, the loop


50


is attached to the animal. When attached, the handle


32


is rotated in a direction where the cable


48


is retracted around the crank shaft


30


raising the animal


52


to a level above the pens


3


. Then the carriage assembly


16


is moved on the track


12


to a position above the depository station where the handle


32


is rotated in a direction releasing the cable


48


from the crank shaft


30


and lowering the animal


52


onto or into the depository station.




The winch


28


of the embodiment of

FIGS. 4 and 5

is identical to the winch


28


of

FIGS. 2 and 3

.




As can be seen from this disclosure, the objects of this invention have been met. Having thus described the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
