Abstract
Abstract An assembly is illustrated for use in connection with the main cylinder and the like of a carding machine wherein an annular shroud has a segmental portion of reduced thickness for providing a ledge type bearing surface for support and securement directly to the card frame, the shroud also having a bearing receiving recess so that the cylinder mounting shaft may be supported within the shroud. The bearing has a pair of parallel inserts, spaced on each side of the shaft, having thickened inner portions for engaging the inner race of the bearing for removing the bearing while the cylinder is carried within the card frame. The shroud provides an arcuate mounting surface for positioning stationary card flats facilitating the provision of means for resiliently carrying the flats yieldably urging them downwardly while permitting adjustment of the settings.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
76 words
A mounting assembly for stationary flats for a carding machine having a clothed cylinder and an arcuate mounting surface comprising: a pair of upright spaced threaded elements carried for threadable adjustment adjacent an end portion of each flat bearing upon said arcuate mounting surface; pivotal means securing said flat to said arcuate mounting surface intermediate said spaced threaded elements; and resilient means aligned with said pivotal means yieldably urging said flats toward said arcuate mounting means.
Claim 2
Dependent Claim
76 words
A mounting assembly for stationary flats for a carding machine having a clothed cylinder and an arcuate mounting surface comprising: a pair of upright spaced threaded elements carried for threadable adjustment adjacent an end portion of each flat bearing upon said arcuate mounting surface; pivotal means securing said flat to said arcuate mounting surface intermediate said spaced threaded elements; and resilient means aligned with said pivotal means yieldably urging said flats toward said arcuate mounting means.
Claim 3
Dependent Claim
59 words
A mounting assembly for stationary flats for a carding machine having a clothed roll and a mounting surface comprising: a pair of spaced adjustable stops carried adjacent an end portion of each flat bearing upon said mounting surface; pivotal means securing said flat to said mounting means; and resilient means yieldably urging said flats toward said arcuate mounting means.
Claim 4
Dependent Claim
59 words
A mounting assembly for stationary flats for a carding machine having a clothed roll and a mounting surface comprising: a pair of spaced adjustable stops carried adjacent an end portion of each flat bearing upon said mounting surface; pivotal means securing said flat to said mounting means; and resilient means yieldably urging said flats toward said arcuate mounting means.
Claim 5
Dependent Claim
26 words
The structure set forth in claim 2 wherein said pivotal means includes an arcuate enlargement fixed to said shroud mounted for slidable movement within said flat.
Claim 6
Dependent Claim
135 words
A bearing assembly for a carding machine having a roll carried between card frame members for rotation by shafts projecting from opposed ends of the roll comprising: a pair of annular bases each having a bore therein; means fixing each of said bases in an upright position upon a frame member with a shaft projecting through a respective bore; a cylindrical hollow bearing cap for receiving said shaft on one end and being open on the other; a seat for carrying an antifriction means for positioning said shaft thereon within said hollow bearing cap adjacent the other end thereof adjacent said annular base; and means securing said bearing cap to said annular base; whereby should a bearing fail the roll will remain with its shafts positioned within said annular bases fixed to respective frame members.
Claim 7
Dependent Claim
135 words
A bearing assembly for a carding machine having a roll carried between card frame members for rotation by shafts projecting from opposed ends of the roll comprising: a pair of annular bases each having a bore therein; means fixing each of said bases in an upright position upon a frame member with a shaft projecting through a respective bore; a cylindrical hollow bearing cap for receiving said shaft on one end and being open on the other; a seat for carrying an antifriction means for positioning said shaft thereon within said hollow bearing cap adjacent the other end thereof adjacent said annular base; and means securing said bearing cap to said annular base; whereby should a bearing fail the roll will remain with its shafts positioned within said annular bases fixed to respective frame members.
Claim 8
Dependent Claim
78 words
The structure set forth in claim 4 wherein said antifriction means are rolling bearings having inner and outer races and including, spacing means carried between said races and said base providing open slots, a pair of inserts spaced one on each side of said shaft within said slots, a projecting portion carried by said inserts engagable with said inner race independently of said outer race, and means for forcefully separating said base from said means fixing said base.
Claim 9
Dependent Claim
39 words
The structure set forth in claim 4 wherein said means fixing said base in upright position includes a shroud having a bore aligned with said first mentioned bore, and a ledge supporting said shroud upon a card frame member.
Claim 10
Dependent Claim
44 words
The structure set forth in claim 6, wherein said shroud has an arcuate peripheral surface for mounting a stationary carding flat, and including pivotal means securing said flat to said arcuate mounting surface, and resilient means yieldably urging said flats toward said mounting surface.
Claim 11
Dependent Claim
112 words
A bearing assembly for supporting a shaft end for rotation comprising: a base having a shaft receiving bore therein; a cylindrical hollow bearing cap for receiving said shaft on one end and being open on the other; a seat within said bearing cap for carrying the outer race of a rolling bearing means having an inner race positioned upon said shaft; means securing said bearing cap to said base; spacing means carried between said races and said base; a pair of inserts spaced one on each side of said shaft carried by said cap; and a projecting portion carried by said inserts engageable with said inner race independently of said outer race.
Claim 12
Dependent Claim
112 words
A bearing assembly for supporting a shaft end for rotation comprising: a base having a shaft receiving bore therein; a cylindrical hollow bearing cap for receiving said shaft on one end and being open on the other; a seat within said bearing cap for carrying the outer race of a rolling bearing means having an inner race positioned upon said shaft; means securing said bearing cap to said base; spacing means carried between said races and said base; a pair of inserts spaced one on each side of said shaft carried by said cap; and a projecting portion carried by said inserts engageable with said inner race independently of said outer race.
Claim 13
Dependent Claim
18 words
The structure set forth in claim 8 including threaded means for forcefully removing said base from said shaft.
