Ruling riachines. Improvements are patented by Mr. J. in ink reservoirs for pen rulingmachines in which ink is conveyed from thereservoir by threads of wool, etc., to a flannelsupplying the pens constructed with anotched supporting flange F, Fig. i,on thefront to enter between the pen bar I, Fig. 5,and an upper bar H, and with a longitudinally extending rod A* on which is pivoted a shieldC extending over the woodwork to supportthe threads E. The shield may be held inlifted position by a hinged strip J, Fig. reservoirs may be made of aluminiumand of various lengths, and small reservoirsD, Fig. 5, with hook-like flanges may be sup-ported on the ends of the large reservoirs,either inside or outside, and supply ink of adifferent colour to threads extending there-from. Loose-Leaf Binders. In a loose-leaf binder, invented by Mr. , the leaves are held between clamping-plates by longitudinally adjustable holdingdevices, have unslotted holes surroundingthese, and have slotted perforations to engageguide pins used during the leaf changingoperation. One or both of the clamping-plates are preferably made of soft metal, hav-ing harder metai brushes to receive the screwends of the pins. In the form shown, the rails2, 2^, to which are hinged the covers 3, areclamped together by suita
