bad employed for this purpose. There were many articles which the Plaintiff had abridged from English Authors, which the Defendants had copied; he could not point out the specific passages, but he would get his Client to make an affidavit of what they were, when he trusted his Lordship could have no doubt as to granting the injunction.

The Lord Chancellor observed, that he would wish Sir S. Romilly would have the affidavit made. The Court was always unwilling to grant injunctions as to part of a publication, without the fullest evidence, as it generally stopped the sale of the whole book; but if a person mixed bad company with good, the latter must be liable for the sins of the former. He would at present grant the Injunction against the translations, at the same time enjoining the Plaintiff to bring his Action forthwith in a Court of Law.

July 25th.

Sir S. Romilly stated, that the Plaintiff had made the affidavit required by his Lordship; and he therefore trusted that he would grant the Injunction prayed for.

The Lord Chancellor,-" Take the Injunction; and, as I suppose the Plaintiff will bring his Action at Law, the Defendants may be at liberty to apply to the Court after the trial."

Mr. Leach, I shall not advise my Clients to defend the Action; I imagine there can be no question as to the Law. Injunction granted.

Specification of the Patent granted to JOHN RUTHVEN, of Edinburgh, Printer; for a Machine, or Press, for printing from Types, Blocks, or other Surfaces. Dated November 1, 1813.

With a Plate.

To all to whom these presents shall come, &c. NOW KNOW YE, that in compliance with the said proviso, I the said John Ruthven do hereby declare that the nature of my said invention, and in what manner the same is to be performed, are particularly described and ascertained in manner following; that is to say: My printing press differs from those heretofore used in the following particulars. 1st. The types, plates, blocks, or other surfaces from which the impression is to be taken, instead of being situated upon a running carriage, as heretofore practised in printing presses, are placed upon a stationary platform or tablet, which is provided with the usual apparatus known to printers by the names of tympan and frisket, with points, &c. to receive the sheet of paper, and convey it to its proper situation on the VOL. XXV.-SECOND SERIES.

types, after they have been inked. 2d. The machinery by which the power for the pressure is produced is situ ated immediately beneath this platform or tablet; and the platen or surface which is opposed to the face of the types, to press the sheet of paper against them, can be brought over the types, and connected at two opposite sides or ends with the machinery beneath the tablet: by this machinery it is so forcibly pressed or drawn down upon the paper, which lays upon the types, as to give the impression; which being thus made, the platen can be disunited from the machinery, and removed from off the types by the foot, or otherwise, to take out the paper, and introduce a fresh sheet. 3d. The said machinery for producing the pressure is a combination of levers, actuated by a crank, or short lever, turned by a winch, or handle, to which the pressman applies his hand; or the pressure may be produced by the tread of the foot.

These particulars of my invention admit of various forms, or modes of construction; but those which I have found by experience to be most applicable and convenient for practice are described by the drawings hereunto annexed; in which Fig. 1 (Plate IX.) is a horizontal plan of a printing press; Fig. 2 a vertical section, taken through the middle; and Fig. 3 an end view: the same letters of reference being used in every one. A A represent the tablet or surface upon which the types, &c. are laid; its surface truly flat, and may be made of wood, stone, or metal, or any other substance used for the carriage of printing presses; but I commonly have it made of castiron. This tablet is mounted upon a frame of wood, or metal, consisting of legs, B B, and cross braces, CC; or any other kind of support may be used which will firmly sustain the tablet at a proper height from the ground. The tablet has the tympan 8 and 9 jointed to it

at

at the end 9, in the usual manner, and open into the position of the dotted lines 10, to take off or put on the sheet of paper, which is confined by the frisket 11, in the usual manner: the dotted lines 12 represent the gallows or support for the tympan and frisket when opened.

For fastening the types upon the tablet, or what the printers call making register, quoins or wedges may be introduced at the angles, in the usual manner; but a method which I prefer is to have screws, 18 13, fitted through pieces, which are made fast to the sides of the tablet; aad between the points of these screws the chase, or frame of types, is held steady upon the tablet, and may be adjusted. Beneath the tablet are the levers marked DE DE, their fulcrums, or fixed centre pins, being at D, and they act upon double hooks, or clutches, F F. When the ends E are depressed by means of the third lever IG, situated beneath and common to both, the connection being made by the link a, the fulcrum of the lever is at G; and H is a third point to which the power to actuate it is applied by a connecting rod K, the opposite end of which is jointed to a crank or short lever LM, situated upon an axis or spindle L, which extends to the front of the machine, and has a winch or handle N, Fig. 1, upon it for the pressman to turn it by. The platen of the press is shewn at OO: it may be made of wood or iron, as usual, but must be exactly true on the lower surface, which applies to the face of types b b, upon the tablet A A. On the top of the platen is a strong metal bar P, which may be either cast in one piece with it, or united to it by screws, at rr: at its extremities it has bolts, dd, fixed to it by screws, or otherwise; and at their lower ends they have heads, which are exactly fitied to the clutches, or double hooks, FF, before described. By means of these the platen is connected with Cc 2

the

the lever DE DE, so that a pressure may be produced when the handle N is turned in the direction shewn by the arrow in Fig. 2. This, by turning the lever M about upon its centre L, pushes the rod K, which, acting upon the point H of the lever G H I, moves it upon its centre G, and depresses the point I, which being connected with the extremities E of the levers D E, by the link a, they are made to partake of its motion, and draw down the platen upon the types by the clutches F F and hooks dd. By returning the winch N to its original position the pressure is relieved, and the platen may be removed from the types thus: at the ends of the bar P two springs, ee, Figs. 1 and 3, are fixed; and in the ends of these, rollers or wheels marked ƒ, are fitted, to revolve freely upon their centre pins. These wheels, having grooves in their edges, run upon sharp angles, formed upon the upper edge of two rails R R, which are extended across the frame of the press, and project sufficiently behind, as in Figs. 1 and S. being supported by brackets g, of Fig. 3, if necessary. Upon these bars and wheels (or sliders may be used in lieu of wheels) the platen will run freely, to remove it backwards off the types, but when brought over them the bolts dd will enter the clutches FF, ready to receive the action of the levers, and give the pressure upon the tympan. The springs e are so adjusted, that when the platen runs backwards or forwards upon the rails R, the under surface of it will be sufficiently raised above the tympan to run clear of it; but when the hooks d d and F F are united, and the pressure given by turning the handle N, these springs yield, though they have sufficient strength to raise up the platen clear of the tympan the instant the pressure is relieved. To draw the platen forward over the types a handle h is fixed upon it, for the pressman to take hold by; but it may be

brought
