Abstract
Abstract For use in spin art decorating, the stretcher is constructed with an expanse of resilient material for supportingly engaging the undersurface of a section of fabric whose outer surface is to receive the liquid coloring agent. The resilient material is suspended by a rectangular rigid frame which is provided with flanges having a series of notches selectably engageable with pins at opposite ends of a carrier arm or beam thereby enabling selection of any one of a number of points for the center of revolution when the frame and article mounted thereon is spun. The stretcher facilitates even application from squeeze bottles of the coloring agents to the garment fabric that is mounted on the stretcher, reduces vibration during spinning, eliminates coloring agent build-up at the geometric center of the stretcher, enhances drying, and yields other advantages.

Claim 1
Independent Claim
213 words
A stretcher for use in a spin art machine in which a rotating carrier member engages the stretcher and spins the stretcher about a spin axis so as to spread over the surface of a fabric mounted on the stretcher, under the action of centrifugal force, a liquid coloring agent that has been applied to said fabric surface, said stretcher comprising in combination: an expanse of resilient material adapted to absorb pressure applied at the point of application of the coloring agent, thereby promoting smooth, continuous application thereof; means suspending said resilient material for supportingly engaging the undersurface of a section of said fabric whose outer surface is to receive said coloring agent, said means including means for maintaining out of engagement with said resilient material any portion of said fabric that extends around and behind said expense of material, said suspending means comprising a perimetric frame suspending said resilient material substantially in a plane; and means for enabling a rotatable carrier to engage said resilient material suspending means at opposite ends thereof along a selectable one of a group of parallel straight lines so that said stretcher may be spun about a selectable axis normal to the plane of said resilient material, said axis passing through the mid-point of the selected line.
