Abstract
Abstract A slide gate for mounting over a wall opening or in a channel. The gate includes a frame assembly which surrounds the wall opening, or which is fixed in the channel, a slide assembly mounted within the frame assembly for vertical movement between an open and a closed position, and operating means carried by the frame assembly. The operating means, which is connected to the slide assembly by a stem, operates to impart vertical movement to the slide assembly. The slide assembly includes a flat plate or disc reinforced by vertically spaced horizontal ribs. At least the lowermost rib is specially adapted to hold a resilient seal, the latter cooperating with the bottom member of the frame assembly when the slide assembly is closed. The side members of the frame assembly each provide parallel grooves into which the side edges of the flat plate or disc and the ends of the horizontal reinforcing ribs protrude. The upper ends of the frame side members are permanently interconnected by yoke members which are adapted to support the operating means, and which are laterally spaced to permit the slide assembly and its connecting stem to be removed from the frame assembly as a single unit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
246 words
A slide gate adapted for mounting in an open space defined for example by the edges of a wall opening or the bottom and side walls of an open channel, said gate comprising: a frame assembly having a bottom member extending along the bottom of the open space, a pair of side members connected to and extending upwardly from said bottom member along the sides of the open space, said side members defining guide means facing inwardly towards the center of the open space, and yoke members interconnecting the upper ends of said side members, said yoke members being permanently and directly attached to and laterally spaced by said side members; a slide assembly located between said side members for vertical movement in relation thereto towards and away from said bottom member, said slide assembly including a flat disc member reinforced by a plurality of vertically spaced reinforcing ribs, the edges of said flat disc member and the ends of said reinforcing ribs protruding laterally into said guide means; operating means removably mounted on said yoke members; and connecting means connecting said operating means to said gate assembly, said operating means being operable to adjust the vertical position of said slide assembly relative to the bottom member of said frame assembly, the lateral spacing between said yoke members being sufficient to permit vertical removal from said frame assembly of said connecting means and said slide assembly following disconnection of said operating means from said yoke members.
Claim 2
Dependent Claim
246 words
A slide gate adapted for mounting in an open space defined for example by the edges of a wall opening or the bottom and side walls of an open channel, said gate comprising: a frame assembly having a bottom member extending along the bottom of the open space, a pair of side members connected to and extending upwardly from said bottom member along the sides of the open space, said side members defining guide means facing inwardly towards the center of the open space, and yoke members interconnecting the upper ends of said side members, said yoke members being permanently and directly attached to and laterally spaced by said side members; a slide assembly located between said side members for vertical movement in relation thereto towards and away from said bottom member, said slide assembly including a flat disc member reinforced by a plurality of vertically spaced reinforcing ribs, the edges of said flat disc member and the ends of said reinforcing ribs protruding laterally into said guide means; operating means removably mounted on said yoke members; and connecting means connecting said operating means to said gate assembly, said operating means being operable to adjust the vertical position of said slide assembly relative to the bottom member of said frame assembly, the lateral spacing between said yoke members being sufficient to permit vertical removal from said frame assembly of said connecting means and said slide assembly following disconnection of said operating means from said yoke members.
Claim 3
Dependent Claim
54 words
The apparatus as claimed in claim 1 wherein said side members are each provided along the lengths thereof with front and rear laterally extending flanges interconnected by an intermediate web portion, each of said flanges being further provided with elongated grooves which provide an interlocking feature when the side members are embedded in concrete.
Claim 4
Dependent Claim
53 words
The apparatus as claimed in claim 2 wherein said guide means is comprised of a pair of grooves, one of said grooves being defined by said intermediate web pOrtion and said rear flange, the other of said grooves located In said front flange and being substantially narrower in width than said first groove.
Claim 5
Dependent Claim
44 words
The apparatus as claimed in claim 3 wherein at least the lowest of said reinforcing ribs is provided with a bottom flange which is undercut adjacent the end thereof to provide a welding groove when the reinforcing rib is attached to said flat disc.
Claim 6
Dependent Claim
32 words
The apparatus as claimed in claim 4 wherein the bottom flange of the lowermost of said reinforcing ribs is further provided with a downwardly facing groove located rearwardly of said welding groove.
Claim 7
Dependent Claim
70 words
The apparatus as claimed in claim 5 wherein the bottom flange of the lowest of said reinforcing ribs is flush with the bottom edge of said flat disc, there being further provided a resilient seal member attached to said bottom flange, said resilient seal having a portion received in the downwardly facing groove in said bottom flange, and another portion extending forwardly beneath the bottom edge of said flat disc.
Claim 8
Dependent Claim
38 words
The apparatus as claimed in claim 1 wherein said connecting means includes a threaded stem extending downwardly from said operating means, the lower end of said stem being threaded in a stem connector attached to said slide assembly.
Claim 9
Dependent Claim
55 words
The apparatus as claimed in claim 7 wherein said stem connector is provided with an upper section adapted to fit in the corner defined by said flat disc member and the upper surface of the uppermost reinforcing rib, said stem connector being further provided with a depending tail portion which overlaps said uppermost reinforcing member.
Claim 10
Dependent Claim
33 words
The apparatus as claimed in claim 8 wherein said stem connector is further provided with laterally spaced reinforcing ribs which extend vertically along said upper section and the tail portion depending downwardly therefrom.
Claim 11
Dependent Claim
62 words
The apparatus as claimed in claim 9 further characterized by a first transverse passageway in said threaded stem adjacent to the lower end thereof, a second passageway extending transversally through said stem connection, said second passageway being elongated vertically, and a locking pin extending through said first and second passageways to prevent rotation of said threaded stem relative to said stem connector.
