CARD CUTTING

Mr. Dick in son’s patent machine for cutting cards, consists of a pair of rollers with circular revolving cutters, the edges of which are intended to act against each other as circular shears, and the pasteboards in pa ing between these rollers are cut by the circular shears into cards of the desired dimensions. These rollers are mounted in suitable standards, with proper adjustments, and are made to revolve by a band and pulley connected to the axle of a crank, or by any other convenient means. IMG:4147767755307473660_illo0259.png:Card cutter Fig. 263. is a front view of this machine; a a and b b are the two rollers, the upper one turning upon an extended axle, bearing in the standards, the lower one upon pivots. These rollers are formed by a series of circular blocks, between a series of circular steel cutters, which are slidden on to iron shafts, and held together upon their axle by nuts screwed up at their ends. The accurate adjustment of the cutters is of the first importance to their correct performance; it is therefore found nece ary to introduce spiral springs within the blocks, in order to pre the cutters up to their proper bearings. A section of one of the blocks is shewn at fig. 265 , and an end view of the same at fig. 266 , with the spiral springs inserted. At the outer extremity of the axle of the roller a , a rigger c , is attached, whence a band pa es to a pulley d , on the crank shaft e , to which a flywheel f , is affixed, for the purpose of rendering the action uniform. Rotatory motion being given to the crank shaft, the upper roller is turned, the lower roller moving at the same time by the friction against the edges of the cutters. Fig. 264 is an end view of the rollers, showing the manner in which the pasteboards are guided and conducted between the cutters. In the front of the machine a movable frame g , is to be placed, for the purpose of receiving the pasteboards, preparatory to cutting them into cards, and a stop is screwed to this frame for the edge of the pasteboard to bear against, which stop is adjustable to suit different sizes. From the back part of this frame an arm h , extends, the extremity of which acts against the periphery of a ratchet wheel i , fixed at the end of the roller b , and hence, as the roller goes round, the frame is made to rise and fall upon its pivots, for the purpose of guiding the pasteboard up to the cutters; at the same time a rod k , hanging in arms from the sides of the standards (shewn by dots in fig. 263 ), falling upon the pasteboard, confines it, while the cutters take hold, and racks, corresponding with the indentations of the rollers, are placed as at l l , by means of which the cards, when cut, are pushed out of the grooves. As various widths of cards will require to be cut by this machine, the patentee proposes to have several pairs of rollers ready adjusted to act together, when mounted in the standards, in preference to shifting the circular cutters, and introducing blocks of greater or le width. The second part of the invention is a machine for pasting the papers, and pre ing the sheets together to make pasteboard. This machine consists of several reels (we suppose rollers are intended) on which the paper is to be wound, along with a paste trough, and rotatory brushes. The several parts of this machine, and their operations in making pasteboard, are described in the specification, but the patentee having omitted the letters of reference in the drawing which he has enrolled, it becomes difficult to explain it. As far as we are enabled to understand the machine, it appears, that damped paper is to be wound upon two rollers, and conducted from thence over two other rollers; that two fluted rollers revolving in the paste trough are to supply paste to two circular brushes, and that by those brushes the papers are to be pasted upon one side, and then pre ed together, to make the pasteboard; after this, the pasteboard is to be drawn on to a table, and to remain there until sufficiently dry to be wound upon other rollers. By comparing this description with the figure , perhaps the intended operations of the machine may be discovered, it is the best explanation we are enabled to give.
