Abstract
Abstract An animal loading chute with retractable landing gear and capable of serving as a loading chute, a holding chute and a trailer device. A first shaft is secured to and extends beneath the floor of the chute and has triangular supports pivotally secured, at one point thereof, to the opposite ends thereof. Each of the triangular supports has an axle spindle extending from its second point which has a wheel mounted thereon. A winch means is connected to the third points of the triangular supports for selectively pivoting the supports with respect to the chute so that the wheels will be raised and lowered with respect to the chute. A removable safety bar selectively interconnects the triangular supports when the chute is being used as a trailer device. A spray attachment is also provided on the chute for spraying disinfectant or the like on the animal in the chute.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
164 words
A trailer with retractable landing gear comprising, a bed portion having opposite sides, a first shaft secured to and extending beneath said bed portion, the opposite ends of said first shaft being positioned outwardly of said sides of said bed portion, a first support means pivotally secured to one end of said first shaft, a second support means pivotally secured to the other end of said first shaft, first and second wheel members operatively rotatably secured to said first and second support means respectively, a winch means on said bed portion connected to said support means for selectively pivoting said support means with respect to said bed portion to cause said wheel members to be relatively raised and lowered with respect to said bed portion so that said bed portion may be lowered to a substantially horizontally disposed position closely adjacent the ground for loading purposes and so that said bed portion may be raised upwardly from said loading position to a transport position.
Claim 2
Dependent Claim
164 words
A trailer with retractable landing gear comprising, a bed portion having opposite sides, a first shaft secured to and extending beneath said bed portion, the opposite ends of said first shaft being positioned outwardly of said sides of said bed portion, a first support means pivotally secured to one end of said first shaft, a second support means pivotally secured to the other end of said first shaft, first and second wheel members operatively rotatably secured to said first and second support means respectively, a winch means on said bed portion connected to said support means for selectively pivoting said support means with respect to said bed portion to cause said wheel members to be relatively raised and lowered with respect to said bed portion so that said bed portion may be lowered to a substantially horizontally disposed position closely adjacent the ground for loading purposes and so that said bed portion may be raised upwardly from said loading position to a transport position.
