2073. Edwards, E., [Fullard, W.]. Feb. 1. Embossing. - Relates to a press which may be employed for embossing metallic sheets. The die D is secured to a chuck comprising a base-plate D<1> and jaws d<4>, d<5> which can be adjusted by means of a right and left handed screw D<3>. The plate D' slides between guides a<3> and is connected to a plunger R<2>, fitting within a tubular portion r<7> of a lever R' which is pivoted at R<8> to the framing A and is oscillated by means of levers L, R and cam s<3> mounted on a countershaft S<2>; the lever R carries a cam roller r, and its upper end is provided with a roller r<4> which engages with a slot l formed in the lower side of lever L. During the traverse of the chuck along the guides a<3>, the die passes successively beneath an inking-plate I<4>, and wiping-pad, and into position ready for embossing. The inking- plate I<4> is fitted within a recess in a carriage I which slides along guideways a' under the action of the links L<4>, L<3>, lever H, link L<2>, and lever L. The plate I<4> is connected to the carriage by means of four rods t<6>, which pass through bosses i<8> and are encircled by coiled springs which bear against cross-rods ; by means of the rods t<6> and a central screw T<3>, the plate I<4> is vertically adjustable. Inking-rollers i<3>, i<4> are mounted upon oscillating plates I<6> which are tilted by means of spring- controlled levers I<10>, arranged to strike against stops t<21>, t<23> during the traverse of the ink carriage. During the forward traverse, the die, the plate D', and the ink carriage mutually approach each other, and the die passes beneath and is inked by the roller i<3>, which is the lower of the two inking-rollers during this first phase of the inking-operation ; the plate D' and ink carriage then return to their original positions, and the die passes beneath and is inked by the roller i<4>, which, owing to the action of the stops and levers I<10>, is then lower than the roller i<3>. Just before the actual inking operations, the inking-rollers are raised by means of cams, and then suddenly released, so that the rollers are caused to dab the die. A wiping-strip passes from a roll W, beneath a wiper plate P<3>, between feed-rolls W<1>, W<3> and on to a winding-roll W<4>. The rolls W<1>, W<3> are formed with fine longitudinal grooves, and the rolls W<3> are pressed towards the roll W<1> by springs U<9>, which are adjustable by means of screws w<15>. The roll W<1> is rotated intermittently by a ratchetwheel and pawl actuated by means of a rack bar N<4> which is adjustably attached to a slotted disc N<3> mounted on a shaft N<1> to which motion is transmitted from shaft S by toothed wheels S<1>, N. The ratchet-wheel is fixed to a pulley N<8> which transmits an intermittent rotation to the winding- roll W<4>, by means of a belt M and pulley M', a suitable friction clutch being interposed to prevent overwinding. The wiper plate P<3> is covered by a strip of felt, the tension of which can be regulated by turning a drum p<22> over which one end of the strip is wound ; the wiper plate itself is yieldingly attached by means of adjustable springs p<17>, an elastic pad p<14>, and slotted lugs, to a crosshead P which slides between guides p<1>and is normally supported by adjustable springs P". When the inked die is passing beneath the wiper plate, the crosshead P is forced down by the action of toggle-levers o<17>, o<11> actuated by an arm o<7>, link o<6> of adjustable length, pivoted lever o<1>, and a combination of two adjustable cams o<1>, o which are mounted upon shaft N'. As the plate D' and connected parts are completing their return stroke, the momentum is destroyed by a buffer block k, and the plate is brought into the correct position for embossing by means of two plate springs V, having V-shaped parts v<2> which enter corresponding apertures formed in the plate. The upper die is mounted in a block B<2>, which is fitted within vertical guides B<1> and is normally held in a raised position by adjustable coiled springs. The block B<2> is connected by a connecting-rod b<13>, of adjustable length, to a lever B<21>, which is mounted in eccentric liners C' and is oscillated by a cam N<2> carried by the shaft N'. The position of the eccentric bearings may be adjustable by means of the hand-lever c<14>, Fig. 1, connected by rods c<6> to cranks c<4> on the eccentric liners, or the adjustment may be effected by other means. Instead of using two rollers i<3>, i<4>, only one inking-roller may be employed, or a brush may be used instead of inking-rollers. The machine may be employed for plain or uncoloured embossing, or for embossing metallic sheets, unguents being employed in the latter case, instead of ink. For keeping the roller on the lever R, Fig 1, against the cam portion s<5> of the cam s<3>, the outer portion s<4> of the cam may be dispensed with, and a spring may be employed.
