Abstract
A self-locking support for tubular members embodying two annular supporting members eccentrically mounted on a shaft and rotatable relative to each other.
Claims8
A support for rotatably supporting a tubular member comprising
- a. an elongated shaft,
- b. an annular member mounted on and extending around said shaft in eccentric relation thereto,
- c. a second annular member mounted on and extending around said shaft in eccentric relation thereto, and
- d. a third annular member mounted on and extending around said shaft,
- e. said annular members being of smaller outside diameter than the inside diameter of such a tubular member and being insertable into said tubular member,
- f. a fourth annular member mounted on said shaft for rotation therearound and eccentric thereto in a direction different from the direction of eccentricity of said first mentioned annular member, and
- g. said second annular member being rotatable around said fourth annular member relative to said first mentioned annular member into position wherein said first mentioned and said second annular members are effective to apply angularly displaced outwardly directed forces on the interior of said tubular member mounted thereon for securing said tubular member against rotation relative to said first mentioned and second annular members.

A support for rotatably supporting an elongated substantially straight tubular member on an elongated shaft extending longitudinally through said member, said support comprising,
- a. two annular members mounted on said shaft in surrounding relation thereto for insertion into such a tubular member in supporting relation to respective end portions thereof,
- b. said annular members being secured to said shaft for rotation therewith,
- c. an annular hub portion integral with one of said members and extending axially therefrom, said hub member having a substantially circular outside circumference smaller than said one member and eccentrically disposed relative to said shaft,
- d. a third annular member mounted on said hub portion in surrounding relation thereto for insertion into said tubular member in supporting relation thereto,
- e. all of said annular members having substantially circular outer peripheries, and
- f. said third member being rotatable around said hub portion and shaft relative to said one member between
- 1. one position wherein the outer peripheries of said third and one members are disposed substantially in axial alignment with each other for receiving said tubular member thereon, and
- 2. another position wherein the outer peripheries of said third and other members project outwardly beyond each other in different directions for positively abuttingly engaging the outwardly projecting portions of said third and one members with the interior surface of said tubular fmember and thereby releasably locking said tubular member thereon for rotation with said third and other members.

In a support for rotatably supporting an elongated, substantially straight tubular member on a substantially horizontally extending, elongated shaft extending longitudinally therethrough, the combination of
- a. an annular member
- 1. mounted on said shaft in surrounding relation thereto, and
- 2. secured to said shaft for rotation therewith,
- b. said annular member comprising
- 1. a central body portion,
- 2. a radially outwardly projecting flange at one side of said body portion, and
- 3. a hub portion of smaller circumference than said body portion projecting outwardly from the side of said body portion remote from said flange,
- c. the outer peripheries of said body portion and said hub portion being eccentric to said shaft in different directions,
- d. another annular member
- 1. mounted on the outer periphery of said hub portion, and
- 2. having an outer periphery that is eccentric to said outer periphery of said hub portion
- e. said other annular member being rotatable around said outer periphery of said hub portion between
- 1. one position wherein said outer periphery of said other member is disposed in axial alignment with said outer periphery of said body portion in position to receive said tubular member on said last mentioned peripheries in surrounding relation thereto and with said tubular member disposed in axially abutting engagement with said flange, and
- 2. another position wherein said outer peripheries of said other member and of said body portion are eccentric in different directions to said shaft in position to positively abuttingly engage the internal surface of said tubular member so mounted thereon for locking said tubular member, said other member and said body portion together for rotation with each other.
