Caster assembly

An assembly for mounting a roller rotatably mounted on an elongated member, said assembly comprising a support member having a bore hole therein for receiving the elongated member;

• a planar metal plate having an opening and a first plurality of slender elongated nail-like teeth struck therefrom to project outwardly from a side face of said plate and leaving a second plurality of corresponding slots in said plate such that at least one of said teeth extends from each of said slots, said plate being secured to said support member with said teeth thereof being embedded in one side of said support member and with said opening in said plate being aligned with said bore hole in said support member;
• and a resilient member having a central opening therein with inner dimensions less than the smallest dimension of said opening in said plate, said resilient member being adapted to be positioned between said plate and said support member with the central axis of said resilient member being in alignment with said opening in said plate and the longitudinal axis of said bore hole, whereby when the elongated member is attached to said support member, the elongated member passes through said opening in said plate and said resilient member and is gripped by both the edges of said plate surrounding said opening in said plate and the edges of said resilient member surrounding said central opening.

A caster assembly comprising:

• a caster mounted on a generally cylindrical shaft;
• a support member having a bore therein, said shaft being arranged in said bore hole;
• a planar metal plate having a circular opening and a first plurality of slender elongated nail-like teeth struck therefrom to project outwardly from a side face of said plate and leaving a second plurality of corresponding slots in said plate such that at least one of said teeth extends from each of said slots, said plate being secured to said support member with said teeth thereof being embedded in one side of said support member and with said opening of said plate being aligned with said bore hole in said support member;
• and a resilient ring having an inner diameter less than the smallest dimension of said opening in said plate, said resilient ring being positioned between said plate and said support member with the central axis of said ring being in alignment with the central axes of said opening in said plate and said bore hole, so that said shaft passes through said opening in said plate and said resilient ring and is gripped by both the edges of said plate surrounding said opening and the inner edges of said resilient ring.
