The groove of this pulley k, is constructed by wedge formed blocks, passed through its sides and meeting each other in opposite directions, so that on drawing out the wedges a short distance, the diameter of the pulley becomes diminished, or by pushing the wedges farther in, the diameter is increased; and the tension wheel p, being suspended in a weighted frame, keeps the band always tight.

As it is necessary that the paper should not continue descending while it is held by the blocks m, m, to be cut, and yet that it should be led on progressively over the roller d, the roller g, which hangs in a lever j, is made to rise at that time, so as to take up the length of paper delivered, and to descend again when the knife is withdrawn. This is effected by a rod r, connected to the crank on the shaft of k, and also to the under part of the lever j, which lever hanging loosely upon the axle of d, as its fulcrumn, and vibrates with the roller g, so as to effect the object in the way described.

The Patentee states that the several individual parts of this machine are not new, and that some of them are to be found included in the specifications of other persons, such as the circular cutters e, which are employed by Mr. Dickinson, and the horizontal cutter h, by Mr. Hansard; he therefore claims only the general arrangement of the parts in the form of a machine for the purpose of cutting paper as the subject of his invention, and present Patent right.-[Inrolled in the Inrolment Office, September, 1828.]

To SAMUEL ROBERTS, of Park Grange, near Sheffield, in the county of York, silver plater, for his having invented certain improvements in plating or coating of copper, or brass, or mixtures of the same, with other metals or materials, with two metals or substances upon each other; as also a method of making such kind of articles or utensils with the said metal when so plated, as have hitherto been made either entirely of silver, or of copper, or of brass, or of a mixture of copper and brass, or coated with silver solely.-[Sealed 26th July, 1830.]

In order to prevent the unpleasant appearance of plated goods, when the silver is partially worn off, the Patentee proposes to plate the copper or brass in the first instance, with the alloy commonly called German silver, and then upon this to plate the silver as heretofore; or the two may be put on together. The same process may be employed in the plating of wire.

It is presumed that the reader is already acquainted with the ordinary process of plating, as the Patentee has not thought it necessary to describe it, but simply furnished us with the above. [Inrolled in the Inrolment Office, September, 1830.]

TO JOSEPH CHARLESWORTH, and JOSHUA CHARLESWORTH, of Holinfirth, woollen manufacturers and merchants, and SAMUEL MELLOR, of the same place, cloth dresser, all in the county of York, for their having invented certain improvements on or additions to gig mills, for the raising and finishing of woollen cloths and other fabrics. [Sealed 18th December, 1828.]

THE improvements proposed under this patent are designed to render the ordinary gig mill more effective

than heretofore, in drawing out the ends of the wool from the cloth, to produce the pile or nap upon its face, and the mode of effecting this is by pressing an elastic substance against the back of the cloth, at that part where the teasles of the gig barrel are acting upon its face.

Plate III. fig. 5, is a side elevation of a gig mill of the usual construction, according to the Yorkshire plan; a, a, a, is the end frame of the gig, commonly constructed of cast iron; b, b, is the gig barrel, the axle of which turns in plummer blocks bearing upon the end frames. The periphery of the gig barrel is covered with teasles or brushes of bristles or wires, which are intended to act upon the face of the cloth as it passes for the purpose of drawing out the ends of the wool, that is raising the pile; c, c, c, is the cloth conducted by rollers d, and e, e, e, as usual, and f, is an adjustable roller, which by being slidden out, partially withdraws the face of the cloth from the gig barrel, and thereby diminishes the operation of the gig upon the cloth when required.

The barrel of the gig is driven through the agency of gear connected to a steam engine, water wheel, or other first mover, by rotary power applied to its axle, which turns with considerable rapidity in the direction of the arrows; the cloth travels in the reverse direction, as shewn by its arrows, being drawn through by the roller d, which also receives its rotary motion by gear from the first mover. A cylindrical brush g, is placed in front of the gig barrel, its hairs pressing with a soft elastic force against the back of the cloth, by which pressure the teasles, or wire cards, or brushes are made to take more effective hold of the ends of the wool than they are enabled to do in the ordinary construction of gig mills.

The Patentees say that they do not intend to confine themselves to the cylindrical brush, as a cushion or

various other elastic substances, if pressed against the back of the cloth at the part when its face is brought in contact with the gig barrel, might answer the purpose nearly as well, and they claim as their invention the application of an elastic substance at the back of the cloth when operated upon in a gig mill as above described.

TO JOHN FERRABEE, of the Thrupp Mill and Foundry, in the parish of Stroud, in the county of Gloucester, engineer, for his having invented improvements in machinery, for preparing the pile or face of woollen or other cloths requiring such process.—[Sealed 23rd December, 1830.]

་

THE object of this invention is to draw out the ends of wool, that is to raise the pile on woollen cloth in diagonal directions across the cloth, instead of raising it lengthwise, as is the case in the ordinary gig mill.

In raising the pile on cloths it is desirable to draw out the ends of the wool in every direction, in order to cover the whole face of the cloth with nap as perfectly as possible, previously to its being submitted to the cropping or shearing operation. The ordinary gig mill will not effect this object completely, as it only draws out the wool in that direction that the cloth travels, and in consequence it is the practice of some clothiers, previous to shearing, to row or brush their cloths on the face with teasles or wire cards, by hand crosswise of the cloth, as well as submitting them to the operation of the gig mill.

The intention of the Patentee is to effect this by machinery, which he does by causing a series of teasle

brushes to traverse across the cloth, while the cloth passes onward through the machine, consequently the pile is raised in diagonal directions instead of lengthwise. Plate III. fig. 6, is a front view of this improved machine; a, is a roller or beam upon which the cloth is wound, as it is drawn off from a similar roller at the back of the machine, but in its progress it is passed over several rollers placed upon the same level as b, which act as a sort of bed to support it.

Rotary motion is given to the machine by a band passed over the rigger c, fixed upon the shaft d, and at the reverse end of this shaft there is a pulley e, from whence a band extends to the pulley f, upon the roller or beam a, which causes the entire length of cloth to be conducted progressively through the machine; when that is done, the cloth is carried back again for a second operation, by throwing the machinery out of gear, and applying the rotary power in the opposite direction.

Upon the shaft d, a toothed wheel g, is fixed, which takes into another toothed wheel h, on the end of the upper shaft; this shaft carries two bevel toothed wheels i, i, which drive similar wheels fixed to the transverse axles mounted in the frame work or standard at k, k. On each of these axles there is also fixed a drum wheel l, l, and on a transverse axle in the middle is also mounted two similar drum wheels m, turning loosely upon their axles; these drum wheels carry the endless bands n, and o, upon each of which is mounted a series of frames or handles containing teasles.

When rotary motion is given to the shaft d, the upper shaft with its bevel wheels i, i, is made to revolve, and also to drive the transverse axles with the drum wheels 7, l, and hence the boards with the teasles traverse across
