Abstract
Abstract A support tray for carrying and transmitting repetitious lateral motion to one or more containers has a plurality of parallel-spaced members extending transverse to the direction of motion and at least one retaining clip. The retaining clip can have upwardly-extending fingers for temporarily positioning a container and a twist lock for releasably engaging the spaced members to transmit lateral motion applied to the tray to the contents of the container and to position the container in a chosen location on the tray. A test tube rack can be fitted with a similar twist lock if it is desired to use one or more test tubes as the containers. The tray also has upwardly-extending handles which are used to transport the tray and support the same while repetitious motion is being transmitted to the container and its contents.

A device for transferring a plurality of containers and transmitting repetitious horizontal motion from two reciprocating horizontally-extending carrier members to the containers which comprises in combination: a bottom, said bottom having a plurality of spaced horizontally-extending parallel members fastened to at least two transverse connecting elements, support means, said support means including a pair of handles spaced above said bottom, at least one link connecting each said handle to said bottom, each said link being adapted to further supportably engage the respective horizontally-extending carrier member for said device to transmit motion from said carrier members to said bottom, and at least one retaining means, said retaining means having means for releasably engaging two of said parallel members, said means for releasably engaging two of said parallel members having an elongated base with a pair of longitudinal ends, said base having a maximum lateral dimension less than the spacing between two of said parallel members and a longitudinal dimension greater than the spacing between two of said parallel members, said longitudinal ends engaging two of said parallel members when said base is rotated to a first position and releasing two of said parallel members upon rotation of about 90° to a second position, said retaining means having gripping means for releasably holding said container at any location intermediate the ends of said parallel members and transmitting motion from said bottom to said container, said longitudinal ends being spaced from said gripping means and said spaced parallel members being held against said gripping means by said longitudinal ends.
