Abstract
Abstract Driven elevator chains are provided with blades passing along an inclined conveyor chute and adjoining grate to remove floating and solid materials from a channel in which the grate is positioned. These elevator chains are guided by lower and upper sprockets, the lower sprockets being mounted in independent suspension on side walls pivotally arranged about the axis of the upper sprockets thereby providing the blades with better mobility.

Claim 1
Independent Claim
312 words
Apparatus for removing floating and solid materials from a channel, said apparatus comprising a support frame; a first vertically inclined member supported by the support frame; said first vertically inclined member including a lower portion comprising a liquid-transmissible grate for extending to the bottom of the channel and further including an adjoining upper portion comprising a conveyer chute leading to a discharge outlet; a drive shaft supported at opposite end portions thereof above the conveyer chute by the support frame; spaced second and third vertically inclined members comprising opposite side walls for the liquid-transmissible grate and adjoining conveyer chute; each of said side walls being supported at the upper end portion thereof by the drive shaft for pivotal movement about the longitudinal axis of the drive shaft independently of the other side wall; first and second pairs of spaced sprockets; each of said first pair of spaced sprockets being operatively connected to the drive shaft adjacent to the upper end portion of an associated different one of the side walls; each of said second pair of spaced sprockets being supported at the lower end portion of an associated different one of the side walls; a pair of spaced endless elevator chains supporting a plurality of successively arranged blades adjacent to the liquid-transmissible grate and adjoining conveyer chute; each of said conveyer chains being supported in operative engagement with the sprockets supported at the upper and lower end portions of an associated different one of the side walls to guide the blades supported by the elevator chains along the transmissible grate and adjoining conveyer chute and thereby permit removal of floating and solid materials from the channel; whereby the side walls and, hence, the elevator chains may be independently displaced at different angles relative to the liquid-transmissible grate and adjoining conveyer chute to facilitate removal of floating and solid materials from the channel.
Claim 2
Dependent Claim
312 words
Apparatus for removing floating and solid materials from a channel, said apparatus comprising a support frame; a first vertically inclined member supported by the support frame; said first vertically inclined member including a lower portion comprising a liquid-transmissible grate for extending to the bottom of the channel and further including an adjoining upper portion comprising a conveyer chute leading to a discharge outlet; a drive shaft supported at opposite end portions thereof above the conveyer chute by the support frame; spaced second and third vertically inclined members comprising opposite side walls for the liquid-transmissible grate and adjoining conveyer chute; each of said side walls being supported at the upper end portion thereof by the drive shaft for pivotal movement about the longitudinal axis of the drive shaft independently of the other side wall; first and second pairs of spaced sprockets; each of said first pair of spaced sprockets being operatively connected to the drive shaft adjacent to the upper end portion of an associated different one of the side walls; each of said second pair of spaced sprockets being supported at the lower end portion of an associated different one of the side walls; a pair of spaced endless elevator chains supporting a plurality of successively arranged blades adjacent to the liquid-transmissible grate and adjoining conveyer chute; each of said conveyer chains being supported in operative engagement with the sprockets supported at the upper and lower end portions of an associated different one of the side walls to guide the blades supported by the elevator chains along the transmissible grate and adjoining conveyer chute and thereby permit removal of floating and solid materials from the channel; whereby the side walls and, hence, the elevator chains may be independently displaced at different angles relative to the liquid-transmissible grate and adjoining conveyer chute to facilitate removal of floating and solid materials from the channel.
Claim 3
Dependent Claim
23 words
Apparatus as in claim 1 wherein the side walls are connected to each other by one or moRe spacing bars of elastic material.
Claim 4
Dependent Claim
40 words
Apparatus as in claim 1 wherein the sprockets supported at the lower end portions of the side walls are tension rollers for the elevator chains and are adjustably and fixably spaced from the sprockets operatively connected to the drive shaft.
Claim 5
Dependent Claim
72 words
Apparatus as in claim 1 wherein the sprockets supported at the lower end portions of the side walls are tension rollers for the elevator chains and are pivoted on the side walls about the longitudinal axis of the drive shaft, and wherein the side walls are adjustably and fixably secured to the drive shaft to permit adjustment of the spacing between those sprockets and the sprockets operatively connected to the drive shaft.
Claim 6
Dependent Claim
31 words
Apparatus as in claim 1 wherein the elevator chains are provided with guide tracks supported on the side walls in the areas of slack and tight portions of the elevator chains.
Claim 7
Dependent Claim
19 words
Apparatus as in claim 5 wherein the guide tracks are rails outflanking the elevator chains from one side thereof.
Claim 8
Dependent Claim
31 words
Apparatus as in claim 1 wherein the support frame is provided with stops for supporting the side walls at a predetermined position relative to the liquid-transmissible grate and adjoining conveyer chute.
Claim 9
Dependent Claim
57 words
Apparatus as in claim 1 wherein the support frame is provided with a stripper mounted on supporting arms in an upper part of the support frame to contact the blades arriving at the discharge outlet and strip the floating and solid materials therefrom, said stripper moving along each successive blade and then dropping into a rest position.
Claim 10
Dependent Claim
24 words
Apparatus as in claim 8 including means supported in the path of motion of the stripper for forcing the stripper against each successive blade.
Claim 11
Dependent Claim

Apparatus as in claim 1 wherein the liquid-transmissible grate comprises a comb.
Claim 12
Dependent Claim
18 words
Apparatus as in claim 1 wherein the liquid-transmissible grate comprises one of a punched-plate screen and a network.
Claim 13
Dependent Claim
87 words
Apparatus as in claim 8 including at least one cleaning brush having a shaft connected to one of the elevator chains, having a body occupied by bristles, and having a gear for rotatably driving the body of the cleaning brush, said apparatus further including a rack corresponding to the gear, said rack being supported on the side wall associated with said one of the elevator chains and being positioned for engaging the gear to rotatably drive the cleaning brush along the liquid-transmissible grate and adjoining conveyer chute.
Claim 14
Dependent Claim
24 words
Apparatus as in claim 12 including a comb connected to at least one of the elevator chains and positioned for engaging the cleaning brush.
Claim 15
Dependent Claim
