A new press has just been introduced to public notice (August 1841), under the patronage of Count Rosen, a Swedish nobleman. There are two of these presses now at work in the extensive establishment of Messrs. William Clowes and Sons, under the name of “The Scandinavian Self-inking Press,” invented by Mr. C. A. Holm, of Stockholm, who has taken out a patent for it.
It is a press with a platen which descends perpendicularly, and at its regular rate of working produces 550 impressions in an hour, which I have ascertained by personal inspection. It requires two boys to each press to lay on and take off the paper, and to turn down and raise the tympan, and one superintendent is fully competent to attend to two presses. By dispensing with woollen blankets in the tympans and substituting paper, it produces fine impressions, as the specimens published of large and finely executed engravings on wood testify. There is a contrivance which causes a rest or pause when the pressure is at its maximum, and gives time for the ink to be firmly attached to the paper. The motive power may be either hand labour or steam, those in use at Messrs. Clowes's establishment are worked by steam; they do not occupy more room than any other press that will print paper of the same dimensions, and are very simple in their construction. The inking apparatus is so arranged that the distributing rollers have three or four different motions, the object and effect of which are to produce a perfectly equal and uniform distribution of the ink. They are manufactured by Messrs. Braithwaite, Milner, and Co., engineers, in the New Road.
