Builder's hardware; a manual for architects, builders and house furnishers . vices, and is somewhat morecomplicated than either of the preceding. Two cog-wheelsgear into each other. The shaft of one wheel is carriedthrough the wall and can be operated by a crank or handle in-side the house. The shaft of the other wheel turns a crank,or bent lever, the end of which works in a slide attached to theface of the blind. The cog-wheels are encased in an iron box,which is shown partly removed in the figure, in order to illus-trate the workings. Aside from the number of parts, which isno very great objection, this shutter-worker has a great deal torecommend it. It is strong and compact, and can act on theshutter with such force that, it is asserted, a child can workthe blind with it in a high wind. It has the advantage of per-mitting the blind to be removed without disturbing the fixtures. One of the simplest acting shutter-workers, is illustrated byFigure 255. This is very ingenious in its idea, consisting of astraight rod set on an angle, with a bent lever on the end.
