Portable working chute system

DETAILED DESCRIPTION OF THE INVENTION In FIG.
1 there is shown a top view of a preferred embodiment of portable working chute system 10 of the invention.
The system includes an elongated platform 12 which has a generally planar upper surface.
The width of the platform is preferably about 8 feet to provide a good working surface and yet allow transport on the highway.
The length of the platform can vary, for example, from about 20 to 40 feet, with 32 feet being preferred.
Upright members or panels 14 and 16 are supported on the upper surface of the platform and form an elongated passageway extending along the length of the platform.
A conventional squeeze chute 20 is preferably secured to the platform in longitudinal alignment with the passageway, as illustrated.
Any type of squeeze chute desired may be used.
A round or tub pen is detachably secured to one end of the platform.
The tub pen includes upper and lower frame sections which are attached at one end to the platform and at their opposite end to an upright post which is spaced from the platform and which serves as the center post of the tub pen.
The tub pen is also illustrated in FIGS.
3 and 4.
Upper frame section 24 includes a downwardly projecting finger at each end.
End 24A is slidably inserted into the upper end of upright post 26 secured to platform 12.
End 24B is detachably connected to the upper end of upright post 30.
End 25A of frame section 25 is pivotably secured to the upper end of upright post 27 carried by platform 12.
End 25B of frame section 25 is welded to the upper end of post 30.
Lower frame section 28 includes an upwardly projecting finger at end 28A which is slidably inserted into the lower end of post 26, as illustrated.
End 28B is welded or secured to circular plate 36.
A vertical or upstanding peg or finger 36A at the center of plate 36 is slidably received in the lower end of post 30, as illustrated.
Lower frame section 29 is pivotably secured to the lower end of post 27.
The opposite end of section 29 is welded to the lower end of post 30
