Abstract: 16,328. Graber, E., and Graber Printing and Ruling Machines Syndicate. July 22. Ruling-machines.-A pen ruling-machine comprises two separate ruling-apparatus, each having its own endless apron and threads for keeping the sheets of paper in contact with the apron. One apron b passes over two rollers b<1>, b<2> mounted in the same horizontal plane, then beneath a roller b<3> mounted below the roller b', and then over rollers b<4>, b<6>, b<7>, and b<8> in succession. The threads d pass over guide-rollers d<1>. The other endless apron c passes over rollers c<1>, c<2>, c<3> and c<4>, arranged in a manner similar to the rollers b<1>, b', b3, and b' to give a loop or dip to the apron, then over rollers c<5>, c<7>, and c<8>, and finally over the roller b<8> and a guide-roller b<5>, which serves also as a guide for the apron b. The threads e pass over guide-rollers e<1>. The tension of the aprons can be adjusted by means of the rollers b<3>, c<3>, which are carried in adjustable bearings. Between the two aprons are endless threads k, passing over rollers k<1>, k<2>, and serving to conduct the sheets of paper, ruled on one side, from the apron b to the apron c, to be ruled on the opposite side. The axles carrying the rollers b', b<6>, b<7>, c', c<5>, and c<7> are geared together by means of chains and sprocket-wheels. The points of the pens g<2> lie over plates l<1> formed with one or more grooves and mounted slightly above the level of the rollers b<1>, b<2> and c', c<2>. Each plate is pivoted at its centre on a cross-bar l', and can be adjusted at an angle with the aprons. The lower part g of the pen slide is extended beyond the upper part, and has a raised edge g<1> with which the pens engage. The pen beam f is mounted on a transverse bar f <1> fixed to adjustable pillars f<2>. The striking-apparatus for use in stop-ruling comprises a lever f<3> pivoted to the pen beam and provided with a rubbing-piece f which is struck periodically by cam-pieces f<8> adjustably attached to a wheel f<9> on the axle h of the roller b'. The position of the lever f can be varied by means of set-screws f<4>,f<5>. The pens may be inked in the usual way or, preferably, by means of the apparatus described in Specification No. 11,126, A.D. 1897. A single rubber tube t for each coloured ink delivers ink to a trough t<1>, whence the flow is regulated by means of taps or cocks t<2>. The cam m, for actuating the controlling-apparatus of the ink supply, is mounted on an oscillatory lever n connected by an eccentricrod u<1> to the starting-lever u. Both controlling- apparatus are actuated from the cam m by means of two pivoted levers m<3>, m<4>. Cams j, on wheels mounted on the axles of the rollers b', c<4> actuate the stop-gates s, used in stop-ruling, by means of levers s<1> connected by links s<3> to arms s<4> on the stop-gate shafts s<5>. In order to allow the apron to be adjusted so as to allow the stop-gates to readily stop very thin paper, an eccentric roller s<7> is adjustably mounted beneath each gate. The feedtable p has adjustable side-guides p' and central guides p<2>. Fig. 7 shows two sets of threads k for transferring two sheets from one apron to the other, and the sheets are squared up in consequence of their being carried against purallel guides a'. The lay boys o have adjustable side-guides, and their feed-rollers are driven so as to deliver the sheets faster than they are received. The delivery table has adjustable stops, transverse and longitudinal, and also reciprocating stops r' for squaring up the sheets as they are delivered.
