Abstract
Abstract A supporting device for a rotary furnace, in which a rod is loosely passed through two frames respectively carrying rollers which rotatably support the furnace. Support members are mounted on the rod for contacting the frames to limit relative longitudinal displacement therebetween and between the rod and the support members while also causing the rollers to be tightly pressed against the furnace along their entire line of contact during the rotation of the furnace.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
176 words
A supporting device for a rotary furnace, comprising a plurality of supports disposed along the length of said furnace, each of said supports comprising a pair of bearing rollers on which said furnace rests; two frames each supporting a respective one of said bearing rollers; a rod loosely passing through said frames; at least one pair of support members disposed on said rod and positioned thereon to limit the mutual longitudinal displacement of said rod and saiD frames; one of said support members of said pair being disposed on one end portion of said rod for contacting one of said frames, the other support member being disposed in the middle portion of said rod for contacting the other frame, said support members and frames having opposed contact surfaces of complimentary spherical shape to permit the frames to individually pivot thereabout under the rotational effect of the furnace and thereby press the rollers against the furnace; cushions filled with a pressurized liquid medium; and a foundation on which said frames rest through the intermediary of said cushions.
Claim 2
Dependent Claim
176 words
A supporting device for a rotary furnace, comprising a plurality of supports disposed along the length of said furnace, each of said supports comprising a pair of bearing rollers on which said furnace rests; two frames each supporting a respective one of said bearing rollers; a rod loosely passing through said frames; at least one pair of support members disposed on said rod and positioned thereon to limit the mutual longitudinal displacement of said rod and saiD frames; one of said support members of said pair being disposed on one end portion of said rod for contacting one of said frames, the other support member being disposed in the middle portion of said rod for contacting the other frame, said support members and frames having opposed contact surfaces of complimentary spherical shape to permit the frames to individually pivot thereabout under the rotational effect of the furnace and thereby press the rollers against the furnace; cushions filled with a pressurized liquid medium; and a foundation on which said frames rest through the intermediary of said cushions.
Claim 3
Dependent Claim
25 words
A device according to claim 1, comprising means by which the position of said support members can be adjusted along the length of said rod.
Claim 4
Dependent Claim
45 words
A device according to claim 1 wherein two pairs of said support members are provided, one pair for contacting the frames in one direction of rotation of the furnace, the other pair for contacting the frames in the other direction of rotation of the furnace.
Claim 5
Dependent Claim
50 words
A device according to claim 3 wherein said frames have inner ends facing one another and outer ends, said one support member of each pair facing a respective inner end of the associated frame, the other support member of each pair facing a respective outer end of the associated frame.
Claim 6
Dependent Claim
38 words
A device according to claim 4 wherein the contact surfaces of one pair of support members are curved in one direction and the contact surfaces of the other pair of support members are curved in the opposite direction.
