A novel invention is Armstrong’s Patent Combined Mallet and Shooting-Stick. This is desirable for general use, and for locking-up forms on the press, or of service where room for the use of the ordinary mallet and shooting-stick is limited to a confined space. [Illustration: MITERING MACHINE.] [Illustration: LEAD CUTTER.] A mitering machine and lead-cutter are among the necessary adjuncts of a printing-office. Perforating Rule is slightly higher than type, and is used in printing coupons and tickets which require to be partially severed while going through the press. It is made of brass or steel. A more convenient (as well as more expensive) article is Ames’s Patent Perforator: its knife, or perforator, lies below the surface of the type while the rollers pass over the form, and rises and makes a clean cut when the impression is on, without injuring the rollers. [Illustration: PERFORATING RULE.] Machines for perforating round holes are manufactured of several sizes. The lowest-priced machine may be worked on a counter, and will perforate every kind of card-board or paper. We give a cut of this style. [Illustration: ROUND HOLE PERFORATING MACHINE.] Imposing Stones may be had with drawers and cases underneath; but these we do not deem advisable, unless the printer be cramped in room, as the cases may be wanted when the stone is in use while imposing or correcting forms. For common use, the plain stone with a single drawer, and without a rim, will be found the nicest. When made otherwise, the rim should be fitted snugly to the stone, or the interstices will become filled with types, dropped in while correcting. [Illustration: IMPOSING STONE.] A very convenient device for the compositor is the Copy-Holder. This, however, is for the book compositor rather than for the jobber. Its utility consists in bringing the copy nearer to the eye of the workman, and in leaving all the boxes at command and uncovered by the manuscript or printed page. There is also a Lamp-Holder which will be found handy where gas is not accessible. [Illustration: COPY-HOLDER.] [Illustration: RUGGLES CARD CUTTER.] Card Cutters are made of several styles, and at prices from fourteen dollars to forty-five; and Paper Cutters are yet more numerous, some of them simple and low-priced, and others massive and costing twelve hundred dollars. We give an engraving of one of moderate price. An extensive run of business only would require the employment of a large paper cutter.
