TO JOHN GOLD, of Birmingham, in the county of Warwick, glasscutter, for improvements in cutting, grinding, smoothing, polishing, or otherwise preparing, glass decanters, and certain other articles.--[Sealed 7th July, 1834.]

THIS invention relates chiefly to the manner of holding decanters and other articles, whilst they are ground and polished.

The first improvement is shewn in Plate XV., at figs. 1, 2, and 3. Fig. 1, is a plan, and fig. 2, a side view, partly in section, of the framing of one of the holders, capable of containing six decanters, a decanter being shewn, in one of the compartments, in order to illustrate the mode of securing the same; and fig. 3, is a front view of the decanter, and part of the framing.

The grinding, smoothing, &c., is effected by a large circular plate or disc a, mounted on the upper end of a vertical shaft; above which plate, near its periphery, and at equal distances apart, three holders, similar to that shewn in the plan, fig. 1, are suspended, by means of their shafts b. The holders each consist of a framing c, with recesses d, d, d, for receiving six decanters, which are secured in the same by means of a frame or cradle e, bolted to the framing c, and the collar f, the decanter being prevented from shifting, by the three wedges g, g,g. When the decanters are secured in their proper places, a revolving motion is communicated to the plate a, and the holders are caused to revolve also, but in the opposite direction, so as to wear the outer portion of the plate equally all round.

The second improvement consists in fastening the decanters in lever holders, actuated by an excentric or other mechanical movement, so as to cause the decanters or other vessels to reciprocate on the grinding or smoothing surface, (which is, in this instance, a bevilled edge or rim, raised round the upper side of the plate a,) and thus tend to keep its face even.

The third improvement consists in an arrangement of apparatus for removing all the decanters that are being operated on at the same time, simultaneously, from the vertical grinding or smoothing plate, and for bringing them in contact with the same simultaneously.

Fig. 4, is a side view of the apparatus, both sides being alike. h, h, h, are seven worm-shafts, connected together at their inner ends, by the bevil pinions i, i, i; the outer end of each shaft carries a nut, fastened to the plate j, through openings in which plate, the ends k, of the decanter-holder, pass, so that the revolution of the worm-shafts will cause the decanters to approach or recede from the grinding-plate or surface l. A rotary motion is communicated to the shafts h, through the pinions i, by turning the handle m, at each side of the machine, and thus the positions of the decanters, with respect to the grinding surface, may be regulated with the greatest nicety.

The fourth improvement consists in securing the holders, containing the decanters, on a sliding frame, which works on guides, so as to cause the decanters or other vessels to assume any position required, with reference to the grinding or smoothing surface.—[Înrolled in the Inrolment Office, January, 1835.]

TO PIERRE BARTHELEMY GUINIBERT DEBAC, of Acre-lane, Brixton, in the county of Surrey, professor of languages and mathematics, at the Polytechnic School, Paris, for an improved machine for weighing, with the means of keeping a register of the operations of the instrument.-[Sealed 26th July, 1834.]

THE weighing machine is shewn in Plate XV., at fig. 1. It consists of a vertical beam a, turning, at its centre, on an axis b, and having, at each end, an arc c, c, the lower end being also loaded with a constant weight d.-e, is a horizontal lever, the front end of which is formed into a segment, and is connected by a small chain, in the manner shewn in the drawing, with the disc f, from which the arms of the beam a, project. The lever e, turns on a centre g, and carries the link h, the lower end of which is forked, and provided with a bolt or screw i, for the purpose of suspending the scale or platform, containing the article to be weighed.

The upper end of the link is formed into a loop, provided with a knife-edge, which rests in a notch in the upper edge of the lever e, the weight of the link and platform being counter-balanced by the weight j, on the tail-end of the lever e.

From the framing k, a flat bar l, descends, terminating at its lower end in a graduated arc m, called the regulating arc, being used for the purpose of regulating the machine; and to the front of the framing another bar n, is attached, supporting, at its upper end, the dial o, upon which the weight of the article is indicated, the fractional parts, and smaller weights, being marked round the outer part of the dial, and the larger weights along a slot in the face of the dial. The smaller weights are pointed out by the hand p, mounted on a spindle, carried by a small cylinder q, shewn by dots in the figure; round this cylinder a cord or chain passes, its ends being secured by the screws, at the under side of the upper arc c, so that the movement of that end of the beam a, caused by the weight of the article suspended from the horizontal lever e, will turn the cylinder, and with it the hand p. The large weights, or rather the number of revolutions of the cylinder q, are shewn by a hand attached to the upper arc, which projects through the slot in the dial.

Fig. 2, is a side view of the apparatus, by which the weight of the different articles weighed by the machine, during a certain

length of time, are registered. When it is used with the weighing machine, the dial o, may be removed, and the registering apparatus provided with a dial.

r, is a cylindrical framing, having its axis s, connected by a cord (in a similar manner to the cylinder q,) with one of the arcs of the vertical beam a, so as to partake of its movements; and upon the end of the axis s, if the registering apparatus is provided with a dial, the hand p, is mounted. The paper on which the weights are to be registered, is wound on a roller t, and proceeds from thence over a roller u, covered with Indiarubber, to the roller v, to which the end of the paper is fastened; and the rollers t, v, are turned a little by weights, every time an article is weighed by the machine, so as to bring a fresh portion of the paper to the upper part of the roller u, to have the weight of the article marked upon it, by the points of the levers w. These levers are mounted upon a long horizontal axis x, and are acted on by a spiral rod, extending from one end of the framing r, to the other, which revolves with it, and depresses the levers w, as different portions of its length come in contact with them, causing them to perforate the paper; the perforations shewing the weight of the article. The tail ends of the levers w, are sufficiently heavy to elevate the points out of the paper, when the spiral rod will permit them to do so, in order that a fresh portion of the paper may be brought beneath them.

The patentee claims, first, the vertical beam, moveable on a centre in one plane, and loaded with one constant weight, which is acted upon by the weight of the body to be weighed, through the medium of a lever, supported near the fulcrum of the vertical beam, as described; the extent of the angular motion of which beam marks the weight of the said body, and causes the registering apparatus to act, by the sole agency or pressure on the machine of the body to be weighed; and secondly, the registering apparatus.—[Inrolled in the Inrolment Office, January, 1835.]

TO WILLIAM HALE, of Colchester, in the county of Essex, civil engineer, for certain improvements in or on windmills, which improvements are applicable to other purposes.-[Sealed 26th July, 1834.]

THIS invention relates to windmills, so constructed, that they move in a horizontal circuit, and is also applicable to tide-mills, the sails or vanes being, in that case, made of wood, or any other suitable substance, instead of sail-cloth. It consists, firstly, in supporting the shafts, which each carry two sails, midway, or at the centre of resistance, whereby the wind or water, pressing respectively on the two sails, will exert an equal degree of force

on each end of the shaft; and secondly, in supporting such windmill on a fixed or stationary post.

In Plate XV., fig. 1, is an elevation, and fig. 2, a plan of this arrangement. a, a, are the shafts, which each carry two sails or vanes, and are supported at either centres by bearings in the ends of the beams b, b; these beams are strengthened by the braces c, c, and d, d, together constituting a frame, which is mounted on a stationary post e, and revolves round the same, having at the lower part of it a cog-wheel f, by which the motion of the frame can be communicated to the mill-stones, or any other machinery required to be driven. Upon the upper end of the post e, is a bevil toothed wheel g, which is kept stationary whilst the mill is at work, but can be turned if the wind changes, in order that the sails may always travel in the same direction. Into this wheel four pinions h,h, keyed on the ends of the shafts i, i, gear; the other ends of the shafts carrying four smaller pinions j, j, take into the bevilled toothed wheels k, k, on the shafts a, a; so that by this arrangement, the sails will be moved half round on their own axes, whilst the frame describes one revolution, and will consequently present their edges to the wind when they are travelling against it, as shewn in fig. 2; the wind is supposed to be proceeding in the direction of the arrows, and it will be seen, that the pairs of sails 1, 2, and 3, which are travelling in the same direction as the wind, will present their sides to it; but the pair of sails 4, which are proceeding in an opposite direction to the wind, present their edges to it, and so offer no resistance.

The patentee claims, first, supporting the shafts or axes a, a, midway, or at the centre of resistance of the sails or vanes, as described, whereby the pressure will be equal on each end of the shaft.

Secondly,-placing such description of mill on a fixed stationary post e, as described.-Inrolled in the Inrolment Office, January, 1835.]

To EDMUND YOULDON, of Exmouth, schoolmaster, for improvements in preventing or curing what are termed smoky chimneys. -[Sealed 5th August, 1834.]

THIS desirable object is effected in the following manner :-On the top of the chimney a cylindrical cover or casing of zinc is fixed, and round the upper part of it eight longitudinal openings are formed, for the passage of air and smoke, being shielded from the wind, in one direction, by curved plates or wind guards, Within the upper part of the casing, are four large curved vanes, affixed to a vertical shaft, which turns, at its lower end, in a bearing carried by a cross framing, and at its 2 U

upper end, in a bearing in the top of the casing, having, near the lower end of it, a toothed wheel, taking into a pinion on the upper end of a short vertical shaft. This shaft carries a fanwheel, of a similar construction to those used in smoke-jacks, and, as the wheel is not quite so large in diameter as the interior of the casing, the remaining space is occupied by a ledge or shelf, so that the smoke will have no means of escape, excepting between the leaves of the fan-wheel.

The action of the apparatus is as follows:-The wind, in whatever direction it may lay, will enter the casing through three of the openings only, and pass out through the others, carrying with it the smoke; but, at the same time, acting on the curved vanes, will cause them to rotate, and by means of the toothed wheel and pinion, above mentioned, communicate a revolving motion to the fan-wheel. The revolution of this wheel, creates a partial exhaustion in the chimney, and consequently, accelerates the ascent of the smoke, which, passing through the fan-wheel, escapes through the openings in the case.

The patentee claims combining the action of the vanes with the fan-wheel, whereby the wind, in giving motion to the vanes, causes the fan-wheel to create an exhaustion below it, and a consequent draft up the chimney, and thus, prevent or cure what are termed smoky chimneys.-[Inrolled in the Inrolment Office, October, 1834.]

TO JAMES PEDDER, of New Radford, in the county of Nottingham, machinist, for certain improvements, applicable to certain machinery for making bobbin net lace, for the purpose of making ornamented bobbin net lace, by the application to such machinery of any or all of the said improvements.-[Sealed 13th August, 1834.]

THESE improvements consist, firstly, in a mode of transmitting the action of the racking wheels to the pusher bars, or other bars of machinery for making ornamental bobbin net lace, that may require occasional extra racking motions to be given to them, by the aid of additional fancy racking wheels, (which are turned round with a much slower motion than the ordinary racking wheels,) in order to produce such variations, in the ordinary' racking motions, as may be requisite for the formation of ornamental patterns in the lace. Secondly, in the application to pusher machinery, of certain long thread guides, which pass downwards between the combs, for the purpose of introducing thick threads, called gimp threads, and bringing the same within reach of the taking-down points, which form the meshes, in order that those threads may be woven into the ornamented lace made by
