|Square - Rectangle Frame|
A common type of frame is shown below. It is made in various sizes; the one here represented measures 18 inches across. It consists of four pieces of wood, two rollers for the top and base and two side pieces. Each of the rollers has a piece of webbing securely nailed along it, and its extremities are pierced with holes to receive the side pieces. These are formed of two long wooden screws, fitted with movable nuts, which adjust the width of the frame and the tautness of the stretched work. The piece of material that is stretched between is the link that keeps the frame together, for the screw ends fit just loosely in the holes of the rollers. The side pieces are sometimes made of flat laths of wood pierced with holes at regular intervals; in these are inserted metal pins, by means of which the work is kept stretched. If the frame is a very large one it can have a strengthening bar fixed across the centre from roller to roller.
The frame is most convenient for work when fixed in a stand, although it can be used leaning against a table or the back of a chair. A very large frame would be supported upon trestles, but for ordinary purposes, a stand, such as the one shown below, is practical. It consists of two upright wooden posts, a little over 2 feet in height, which are connected near the base by a strengthening cross piece. Both this and the uprights are adjustable; the centre part of the posts is arranged to slide up and down, and can be fixed at any convenient height by the insertion of a long metal pin; the width of the cross piece is regulated in similar fashion, being made firm, by a screw, at the required width, thus allowing various sized frames to be used in the same stand. The frame is fixed in place by metal clamps, and a wooden pivot is arranged so as to permit the stretched work to be inclined at any angle convenient. Both stand and frame should be well made and of good wood, for they must be able to stand strain and be perfectly firm and true when fixed for work.
