The effect of this peculiar combination or arrangement of apparatus (forming an expansive and independent bolster) will be, that as the spindle revolves, at a very high velocity, it is thus subjected to the united impulse of the centrifugal and centripetal forces, and caused to revolve centrally and perpendicularly to the plane of the flyer; whilst, at the same time, any requisite amount of drag or resistance may be given, as the cop or bobbin is filled, by lowering the drag or bolster-rail f, f, and thus allowing the ball to act against the conical sides of the spindle, as seen at k, k.

The ball segments, forming an universal joint within the cup, and the socket resting loose on the even drag-rail, will yield to any lateral push of the spindle. The three segments enclose the spindle, and being made to press against it, friction is thereby caused, which gives the desired retardation to the spindle.

As the thread on the spindle, tube, or bobbin, increases in diameter, more friction is required; this is obtained by increasing the diameter of that part of the spindle where the segmental ball and socket act, to a gradual tapering downwards, for about four inches, at the inclination of about one thirty-second part of an inch to the inch in length. By lowering the drag-rail, with its segmental balls and sockets, on to the thicker part of this taper or cone, friction is of course increased, and, by adjusting the lowering of this rail, proportional to the time in which the bobbin or spindle fills, any desired retardation or drag upon the spindle may be obtained.

Fig. 4, represents the improved spindle and flyer, for spinning pin-cops, in the manner before explained, that is, with the cop spun or formed in the reverse position. a, a, represents the spindle; b, b, the short- armed flyer; and c, c, the cop, which is spun or wound on from the top; the arms of the flyer are therefore required to be the exact length of the longest taper of the cop, and no more; this will allow of the flyer running at a very high velocity.

Fig. 5, represents an elevation of a spinning-frame, called a throstle, with the improvements applied thereto; and fig. 6, is an end view of the same.

These figures represent, more particularly, the third and fourth features of the improvements. a, a, a, are the spindles; b, b, b, the bobbins; c, c, c, the flyers; and d, d, the lifting or copping-rail below. The drag-rail, supporting the loose bolsters, is seen at f,f, and the bolsters g, g, are constructed as just explained, with reference to figs. 1, 2, and 3.

Now, in order to impart any required degree of drag or resistance to the spindle, while running at its full velocity, the bolster-rail f, f, is lowered, with its loose bolsters, on the conical part k, k, of the spindle, as the bobbin fills, by means of the mangle-wheel and pinion l, m, actuated by the worms and wheels n, n, o, o, which will be readily understood by the practical spinner.

The application of a morticed swivel-lever to spinning machinery, is also shewn in these figures, and to doubling machinery in fig. 7. p, p, is a morticed vibrating lever, for the purpose of carrying the ordinary change-wheels q, q, to work the twist and draft; and it will be seen, that by the employment of this lever, as the carrier for the changewheels, it being able to turn upon a centre, the change may be more readily accomplished.

Fig. 8, represents an elevation of an arrangement of apparatus, for the purpose of regulating the various motions of the bobbins or spindles in roving, slubbing, or preparing machinery; it consists principally in the substitution of a geared cone a, a, in place of the ordinary strap-cone, used in spinning machinery.

Upon the drawing-shaft b, b, a fast pinion c, is mounted, which drives, by means of the carriers d, d, the spur-wheel e, in gear with the toothed periphery of the cone a, a. This cone a, a, communicates motion to the bobbins, by means of the mangle-pinion and wheel f, f, and spur-wheel g, which is fast upon its boss.

The lifting or cop-motion is communicated to the machine, by means of the wheel h, also driven by the cone a, upon the shaft i, i, and, by means of the jointed-shaft j, to the mangle-pinion k, and wheel l.

It will be seen, that at every revolution of the mangle

wheel l, a pin m, comes in contact with the catch-lever n, (see fig. 9,) and disengages it from the rack o, which has teeth formed alternately on each side. Upon the rack o, being liberated from the lever n, the weighted cord p, brings it down one tooth, and moves the wheel e, which is attached, into gear with the next ring of teeth on the cone a; and so on, at every rise or fall of the bobbin, thus ensuring the regularity of its motion.

The patentee claims, firstly, the application of a moveable independent bolster, placed between the top and bottom of the spindle, that as the spindle revolves therein, the conjoined action of the centrifugal and centripetal forces, in combination with such expansive bolster, shall cause such spindle to revolve centrally and perpendicularly to the plane of the flyer; secondly, the mode of spinning the cop, in a reversed position, by means of a short-armed flyer, the length required being only that of the longest taper of the cop; thirdly, the peculiar arrangement of mechanism, for lowering the bolster or drag-rail; fourthly, the application to spinning, doubling, or twisting machinery, of the morticed swivel-lever, for carrying the change-wheels; and lastly, the peculiar arrangement of mechanism or apparatus, for the purpose of regulating the motions of the bobbins or spindles, in roving, slubbing, and preparing machinery, and particularly the substitution of a cone, composed of toothed gear, and worked by a spur-wheel, instead of having a plain surface, to be worked by a strap. This part of the improvements is also applicable to machinery in general.— [Inrolled in the Rolls Chapel Office, June, 1840.]

TO JAMES CAPPLE MILLER, of Manchester, in the county of Lancaster, Gent., for certain improvements in printing calicoes, muslins, and other fabrics.―[Sealed 15th August, 1839.]

THESE improvements, in printing calicoes, muslins, and other fabrics, consist in a novel arrangement and construction of

mechanism or apparatus, whereby the pattern or design may be printed upon the goods or fabrics, by the agency of machinery, worked by steam or other adequate power.

The peculiar department of printing calicoes, muslins, &c., to which these improvements are more particularly applicable, is that process usually denominated block printing, which is ordinarily performed by manual labour; the design or pattern to be printed, being first traced on the surface of the blocks, and small portions of a single color impressed upon the cloth, by the hands of the workman, the intervening and finishing colors being separately printed at successive intervals.

The advantages attainable by this invention are, firstly, the capability of printing two, three, four, or more colors, at one operation; and secondly, completing the printed pattern upon the whole width of the piece of goods, or upon two or more pieces, side by side, in the same machine; and by having another table, and set of impression boxes and color boxes, the same movements may be applied, so that the carriage, in retiring, may print two or more pieces, and in advancing, print also two more.

In Plate IX., are several views of the improved machine, calculated to print two pieces, or two different patterns, on the same block, of calico, muslin, or other fabric, side by side, (or four pieces, the carriage printing both ways,) the intended pattern or device, to be printed, consisting of four colors, to be printed from blocks.

Fig. 1, represents a side elevation, and fig. 2, a front view of the improved printing machine; fig. 3, represents a transverse section, taken through about the middle of the machine.

The side or main framing of the printing machine, is shewn at a, a, supporting the color-boxes b, b, b, with their "doctors;" the furnishing tables or beds c, c, c, (which are a substitute for the sieve in ordinary block printing); the printing table d, d; and the feeding, drying, and delivering-rollers f, f, g, g, h, h.

The machine is also provided with a carriage i, i, for the printing blocks j,j,j,j. This carriage i, i, travels in and

out, at suitable intervals, upon rails k, k, attached to the main framing

The operation of the machine is effected, by passing a driving-strap l, connected, by shafting, to the steam-engine, or any other adequate power, round the driving-pulley m, fixed at the extremity of the main driving-shaft n, n. At the other end of the shaft n, is keyed the bevil-pinion o, gearing, at suitable intervals, (hereafter explained,) with the bevil-wheel p, which is mounted upon one end of the cross-shaft q; at about the middle of which, the mitrewheels r, r, driving the upright shaft s, s, and mitre-wheels t, t, above, actuate, by means of the spur-pinions u, u, the feeding-rollers ƒ, ƒ, and thus draw the pieces of goods into the machine.

Simultaneously with the progress of the cloth, the mitrewheels v, v, at the other end of the cross-shaft q, drive the furnishing-rollers w, w, w, by means of the spur-gearing X, X, X. The furnishing-rollers, revolving in their respective color-boxes, spread or supply the colors upon the travelling endless blankets y, y, y, which pass around the top roller, and the furnishing-tables or beds c, c, c, in order to supply the colors to the surfaces of the printing blocks j,j,j.

It may be here remarked, that either the beds c, or the backs of the printing blocks, may be made slightly elastic, to insure the perfect taking-up of the color by the blocks.

Supposing now the carriage i, i, to be run out upon its railways, at the farthest point from the beds c, c, it is drawn inwards towards the furnishing-beds c, c, by means of the spur-wheel ≈, upon the driving-shaft n, taking into a small pinion 1, (shewn by dots in fig. 1,) upon the shaft 2. On the end of this shaft is also keyed the mangle-pinion 3, gearing in the mangle-wheel 4, which is keyed upon the end of the shaft 5. This shaft drives the spur-wheel 6, in gear with the pinion 7, fast upon the shaft 8,—see fig. 3.

Upon either end of the shaft 5, is a rack-pinion 9, taking into the horizontal rack 10, fast on the carriage-frame i, i, and thus the blocks j, j, j, are presented to the furnishingblankets y, y, y, and take a supply of color ready for print
