A catch bar is a piece of wood two inches thick, four inches broad and ten inches long, with a groove in the lower part of it by which it is screwed to the front of the off cheek, and may be heightened or lowered at pleasure; the top of it is a little bevilled or sloped off, that the bar may by its spring fly up the bevil till it stick. — M.
This catch is in my opinion superior to the one now used, which is a piece of wood nailed to the far side of the off cheek, with an opening in it, through which a sloping piece projects beyond the front of the cheek, for the bar to slide up. The old one appears much easier to justify, by means of the screw, without having any nails to draw.
In very fine press work, where uniformity of pressure is to be preserved, I would always cheek the bar, or bring it home, every pull, and rest a short time upon it. In large forms, however, this is too much exertion for a man to continue; and to obviate this objection I had a catch made for some wooden presses, which, dropping over the bar, held it close to the cheek, and enabled the pressman to rest upon his pull sufficiently long without the continued strain to his arm. It was screwed to the near cheek, and disengaged from the press bar, by pulling a piece of string attached to its other end through the small hole.
