Abstract
Abstract The invention relates to a cutting gate, adapted to be utilized in the grading or separating of animals such as horses, cows or the like, into two or more holding corrals. The gate according to the invention comprises a first substantially vertical elongate member adapted to be rotatably mounted about a supporting post or standard; two diverging substantially vertical side portions fixedly attached to the first member, to extend radially therefrom and a third forwardly facing side extending between the diverging side portions remote from the first member to define a space, generally triangular in plan. The gate, which is controllable by an operator positioned within the space, is adjustable in height to ensure adequate ground clearance and additional stops may be provided to limit the rotation of the gate about its support. The invention further contemplates the utilization of the novel cutting gate in conjunction with an animal receiving chute and two or more holding pens or corrals. The gate is positioned so that it may be swung from a first position wherein the gate blocks the chute, to a second position wherein animals may be passed to a selected one of the pens or corrals.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
171 words
An animal handling system comprising: (1) an animal receiving chute; (2) a plurality of animal holding pens or corrals having entrances adjacent one end of said chute; (3) a gate supporting post, adapted at its lower end to be engaged with the ground, said post being positioned substantially centrally of said chute adjacent said one end; (4) gate means mounted for rotation about said post from a first operating position wherein said gate means blocks passage through said chute, to second and third positions whereby animals may pass to a selected one of said pens or corrals; said gate means including: (a) a first member, slidably mounted on said post and adapted for rotation about the longitudinal axis thereof; (b) an open, three-sided space-enclosing framework, generally triangular in plan, fixedly attached at its apex to said first member to extend normally and outwardly thereof; and (5) gate positioning means on said post adjacent the lower end thereof, adapted to engage and support said gate means in spaced relation to the ground.
Claim 2
Dependent Claim
171 words
An animal handling system comprising: (1) an animal receiving chute; (2) a plurality of animal holding pens or corrals having entrances adjacent one end of said chute; (3) a gate supporting post, adapted at its lower end to be engaged with the ground, said post being positioned substantially centrally of said chute adjacent said one end; (4) gate means mounted for rotation about said post from a first operating position wherein said gate means blocks passage through said chute, to second and third positions whereby animals may pass to a selected one of said pens or corrals; said gate means including: (a) a first member, slidably mounted on said post and adapted for rotation about the longitudinal axis thereof; (b) an open, three-sided space-enclosing framework, generally triangular in plan, fixedly attached at its apex to said first member to extend normally and outwardly thereof; and (5) gate positioning means on said post adjacent the lower end thereof, adapted to engage and support said gate means in spaced relation to the ground.
Claim 3
Dependent Claim
36 words
The system according to claim 1 further including stop means positioned adjacent said post, on each side thereof, said stop means adapted to engage with said gate means to limit rotational movement thereof about said post.
Claim 4
Dependent Claim
20 words
The system according to claim 2 wherein said stop means comprise vertical posts, spaced apart from said gate supporting post.
Claim 5
Dependent Claim
100 words
The system according to claim 1 wherein said framework comprises first and second generally rectangular longitudinally extending side sections, equal in length and dimensioned so as to block passage through selected ones of said entrances when in said second and third positions, each being fixedly attached along one vertical edge to said first member and extending radially therefrom in diverging relation one to the other, and a third generally rectangular forward facing side section extending between said first and second side sections and of sufficient lateral extent as to block passage through said chute when in said first operating position.
Claim 6
Dependent Claim
50 words
The system according to claim 4, wherein each of said three side sections is curved in the longitudinal direction, said first and second sides being of concave curvature inwardly with respect to said enclosed space, and said third side being of convex curvature outwardly with respect to said enclosed space.
Claim 7
Dependent Claim
14 words
The system according to claim 4 wherein said framework is constructed of tubular members.
Claim 8
Dependent Claim
24 words
The system according to claim 6 wherein said forward facing side section includes a solid opaque panel fixedly attached to the outer surface thereof.
Claim 9
Dependent Claim
34 words
The system according to claim 1 or claim 7 wherein said gate means is manually operated by an operator positioned within said enclosed space, means being provided in said framework to effect entry thereto.
Claim 10
Dependent Claim
28 words
The system according to claim 1 wherein said gate positioning means are releasably attached to said post to permit the location of the gate to be adjustable thereon.
Claim 11
Dependent Claim
64 words
The system according to claim 1 wherein the number of animal holding pens or corrals associated with said system exceeds three, and wherein one or more gates of a conventional type are located adjacent said gate means to be operable in conjunction therewith in order to achieve the passage of said animals to a selected one of said three or more pens or corrals.
Claim 12
Dependent Claim
193 words
An animal cutting gate for use in association with an animal receiving chute leading to two or more animal holding pens or corrals having adjacent entrances, said gate comprising: (a) a gate support post, adapted at its lower extremity to be engaged with the ground; (b) an open, three-sided space-enclosing framework mounted for rotation about said post, said framework including: (i) a first member slidably mounted on said post and adapted for rotation about the longitudinal axis thereof; (ii) first and second generally rectangular, longitudinally extending side sections, equal in length, each being fixedly attached along one vertical edge to said first member and extending radially therefrom in diverging relation one to the other so as to be capable in use of closing one or the other of the entrances, and a third substantially rectangular forward facing side section extending between said first and second side sections, as an extension thereof, remote from said first member so as to be capable in use of closing the chute; and (c) gate positioning means on said post adjacent the lower extremity thereof, adapted to engage and support said gate in spaced relation to the ground.
Claim 13
Dependent Claim
193 words
An animal cutting gate for use in association with an animal receiving chute leading to two or more animal holding pens or corrals having adjacent entrances, said gate comprising: (a) a gate support post, adapted at its lower extremity to be engaged with the ground; (b) an open, three-sided space-enclosing framework mounted for rotation about said post, said framework including: (i) a first member slidably mounted on said post and adapted for rotation about the longitudinal axis thereof; (ii) first and second generally rectangular, longitudinally extending side sections, equal in length, each being fixedly attached along one vertical edge to said first member and extending radially therefrom in diverging relation one to the other so as to be capable in use of closing one or the other of the entrances, and a third substantially rectangular forward facing side section extending between said first and second side sections, as an extension thereof, remote from said first member so as to be capable in use of closing the chute; and (c) gate positioning means on said post adjacent the lower extremity thereof, adapted to engage and support said gate in spaced relation to the ground.
