(c) an elongate side seal disposed in each of said side channel elements, including

a static sealing member having a static sealing face and a hinged sealing member having a positionable sealing face, said static sealing member and said hinged sealing member projecting from a base defining a channel between said static sealing face and said hinged sealing member for receiving said side margin of said gate

(d) an elongate top seal coupled to said intermediate cross member, said elongate top seal including:

i) a longitudinal medial portion secured to said intermediate cross member;

ii) a hinged sealing member coupled by a hinge element along a first side of said longitudinal medial portion, said hinged sealing member providing a positionable sealing face movable about said hinge element to engage said face of said gate below said longitudinal medial portion; and

iii) a shield member coupled along a length of a second side of said longitudinal medial portion which tapers approaching a terminal edge, and further including:

a contact face configured to engage said face of said gate;

a groove element disposed along said length of said shield member in opposed relation to said to said intermediate cross piece;

a cantilever element coupled to said shield member extending over said groove element; and

a resilient member disposed in said groove element, said resilient member engaging said cantilever element to urge said contact face against said face of said gate.

2. The slide gate of claim 1 , wherein said side channel elements of said frame assembly have fixed dimensional relations, and wherein said one piece side seal is disposed in said side channel elements.

3. The slide gate of claim 1 , further comprising a recess element disposed along a length of said longitudinal medial portion of said elongate top seal, said recess element configured to receive within one or more mechanical fasteners in space engagement to secure said longitudinal medial portion to said intermediate cross piece.

4. The slide gate of claim 1 , wherein said elongate top seal coupled to said intermediate cross member has a first end and a second end which abuttingly engage a corresponding one of said elongate side seals disposed in said side channel elements, said first end and said second end of said elongate top seal configured to abuttingly engage said shield member against said hinged sealing member edge of a corresponding one of said elongate side seals, said longitudinal medial portion and said hinged sealing member of said elongate top seal longitudinally extending outward of abutted engagement of said shield member against said hinged sealing member of each said elongate side seal, said longitudinal medial portion extending outward having a medial portion edge, said hinged sealing member extending outward having an angled edge commencing proximate said hinge element and terminating at said hinged sealing member edge, said hinged sealing member of each said elongate side seal having a closed end recess element which receives said longitudinal medial portion and said hinged sealing member extending outwardly, said recess element configured to abuttingly engage said medial portion edge and said angled edge.

5. The slide gate of claim 4 , wherein said closed end recess element has a depth which provides a gap between each of said first end and said second end of said elongate top seal and a closed end of a corresponding one of said closed end recess elements.

6. A method of producing a slide gate, comprising:

(a) providing a frame assembly including:

i) a first gate guide member and a second gate guide member each having a length disposed between a first end and a second end, said gate guide members defining corresponding side channel elements;

ii) an intermediate cross member coupled between said gate guide members at a height between said first ends and said second ends;

(b) extending a gate between said first gate guide member and said second gate guide member, said gate having corresponding side margins having sliding engagement with said channel elements;

(c) disposing an elongate side seal in each of said side channel elements, including:

a static sealing member having a static sealing face and a hinged sealing member having a positionable sealing face, said static sealing member and said hinged sealing member projecting from a base defining a channel between said static sealing face and said hinged sealing member for receiving said side margin of said gate, said hinged sealing member movable about a hinge element coupled to said base to decrease a width of said channel;

(d) coupling an elongate top seal to said intermediate cross member, said elongate top seal including:

i) a longitudinal medial portion secured to said intermediate cross member;

ii) a hinged sealing member coupled by a hinge element along a first side of said longitudinal medial portion, said hinged sealing member providing a positionable sealing face movable about said hinge element to engage a face of said gate below said longitudinal medial portion; and

iii) a shield member coupled along a length of a second side of said longitudinal medial portion which tapers approaching a terminal edge, and further including:

a contact face configured to engage said face of said Gate;

a groove element disposed along said length of said shield member in opposed relation to said to said intermediate cross piece;

a cantilever element coupled to said shield member extending over said groove element; and

a resilient member disposed in said groove element, said resilient member engaging said cantilever element to urge said contact face against said face of said gate.

7. The method of claim 6 , wherein said side channel elements of said frame assembly have fixed dimensional relations, and wherein said one piece side seal is sufficiently flexible to be disposed in said side channel elements.

8. The method of claim 6 , further comprising adjusting dimensional relations and an amount of resiliency of said resilient member alter the force of engagement of said contact face against said face of said gate.

9. The method of claim 6 , further comprising a recess element disposed along a length of said longitudinal medial portion of said elongate top seal, said recess element configured to periodically receive within one or more mechanical fasteners to secure said longitudinal medial portion to said intermediate cross piece.

10. The method of claim 6 , further comprising abuttingly engaging a first end and a second end of said elongate top seal coupled to said intermediate cross member to a corresponding one of said side seals disposed in said side channel elements, said first end and said second end of said elongate top seal configured to abuttingly engage said shield member against said hinged sealing member edge of a corresponding one of said side seals, said longitudinal medial portion and said hinged sealing member of said elongate top seal longitudinally extending outward of abutted engagement of said shield member against said hinged sealing member of each said side seal, said longitudinal medial portion extending outward having a medial portion edge, said hinged sealing member extending outward having an angled edge commencing proximate said hinge element and terminating at said hinged sealing member edge, said hinged sealing member of each side seal having a closed end recess element which receives said longitudinal medial portion and said hinged sealing member extending outwardly, said recess element configured to abuttingly engage said medial portion edge and said angled edge.

11. The method of claim 10 , wherein said closed end recess element has a depth which provides a gap between each of said first end and said second end of said elongate top seal and a closed end of a corresponding one of said closed end recess elements.
