granted me, on mill fpinning machinery, confift principally in an alteration in the conftruction and pofition of the fpindles. By the first method the fpindle is in feveral refpects fimilar to the common fpindle, but it differs in one refpect, viz. that the bobbing does not reit on or touch the copping rail, their contact being prevented by a ring made to fit, aud to rife and fall or traverfe on the fpindle, in which there is a groove cut lengthways; and in this groove a fcrew or pin is made to fit, which paffes through the ring, fo that when the fpindle is made to turn round, the ring muft turn round with it. The ring, or as it is technically denominated the worl, is moved up and down on the spindle by a rail communicating with the heart or other motion, This rail fits into a groove, cut or turned in the brafs or other worl, on which revolving worl, and not on the copping rail, the bottom of the bobbin refts. The uptake of the bobbin is regulated by applying to it a fpring, band, weight, lever, or any other fubitance capable of retarding its revolution." The noble Earl has defcribed three other fpindles, which we fall omit, as he obferves that it is extremely difficult to defcribe all the different varieties of fpindles, whether made in one or two pieces; and he adds, that the prominent features of his im provements are the making the fpindle carry round the bobbin without the action of the yarn or thread, and that whether the fpindles be in one or more pieces; the making the haft or warf at times to fhift or remove from off the fpindle; the retarding the revolutions of the bobbin carried round by the agency of the fpindle, fo as to regulate the uptake of the yarn on the bobbin, by a power connected with the motion of the fpindle, or, in other words, giving the bobbin the motion neceffary to occafion the uptake of the yarn, which is contrary to the principles on which the improved fpindle is conftructed, in which the object is to retard the revolutions of the bobbin, and not to give it motion. The patent fpindles are adapted for making covings, for throwing and twifting thread or yarn of cotton, filk, wool, flax, and hemp; likewife for twifting twine, filing-lines, and ropes of all sizes and defcriptions.

MR. A. G. ECKHARDT'S (BERWICK-STREET), for Improvements in Book-binding. Some years ago, a patent was obtained

for the purpofe of producing freedom in the opening of all forts of books by means of a firm back, applied to a book before it is covered: the prefent invention con fifts in producing the fame effect upon all kinds of books after they are covered, by the fame firm back applied externally; to which is attached by hinges, or flaps, made of the fame materials, to which flaps are connected by hinges of any kind, ledges which completely enclofe the book on all fides, resembling the appearance of a book. The ledges at the bottom, or on the fides, are converted into fupporters for the hand when requisite to write near the bottom or edges of the book; and these poffefs an ability to elevate or deprefs their pofition at pleafure, with a power of being rendered ftationary, by means of a flop or ftops, which are affixed to the flaps. The whole to be fecured by a lock, or other fastening.

MR. CHARLES SCHMALCALDER (LITTLE NEWPORT-STREET), for a Delineator for taking Profiles, &c.

This invention, which (at first sight, at leaft) does not appear the most imple poflible, confifts of a hollow rod, of fe veral parts screwed together, the whole length being from two to twelve feet, or even longer. It may be made of wood or any metal, but copper and brafs are chiefly recommended. One end of this rod carries a fteel tracer, made to flide in and out, and to be fattened by the mill head fcrewed; the other end of the rod having likewife a round hole, to take up either a fteel point, black-lead pencil, or any metallic point, which may be faftened by a milled head fcrew. A tube about ten inches long is fixed in a ball, in diameter fufficient to allow the rod before defcribed to flide easily, but to ftand firmly. The ball with this tube is movable between two half-fockets, form ing together a ball and focket. There is a frame of wood two or three feet long, fupported by two brackets. Through the fides of this frame are holes at certain diftances, correfponding with the marks on the rod, by which originals are copied, to any fize, by the following me thod: The paper, ivory, &c. is faftened upon a fwinging board, either by fcrews, or by a brafs frame formed of two flat pieces of brafs joined together at the end by hinges, and having on the other end two buttons to fasten the paper between,

ealily

There is an opening made to allow the point to mark upon the paper. The dges of the frame form and lide in a dovetail, moveable upon the fwinging board, and kept in a proper fituation by a fpring. On the back of the board is axed a weight with a hook, to which is attached a fpring, forming a pulley, ferving to prevent the point from acting upon the paper when not wanted. The machine is fixed either to a partition in any room, or to a table, or other ftand. The inftrument is perfect, 1, when all the parts are firmly connected, and with out fluctuation; 2, when the ball and fockets are truly circular, and move eafily; 3, when the rod paffes truly through the centre of the ball; 4, when the rod is perfectly straight; 5, in turning the rod round in the fockets, the tracer and point in the two ends of the rod muft remain in the centre: to attain this there must be an adjustment of fcrews. For taking profiles, before the inftrument is fixed to the partition, the height must be taken from the bottom to the middle of the face of a perfon fitting upon a chair, and that height transferred upon the partition in the place where the fockets are faftened: the perfon's head muft reft against a piece of wood lined with leather. The tracing is begun from the back, and the fcrew muft form a right angle with every part of the face in paffing over it; in confequence of which the rod must be turned round in the focket, and the cutter, previoufly fixed in the rod, will cut out the profiles, By means of fome fmall variations, pic tures and landscapes are traced. After this full defcription, we are much in doubt whether a mere mechanical profile is the belt poffible.

DR. CAREY has, we understand, taken out Patents for the following inventions:

1. A ciftern and apparatus, by means of which a fire breaking out in a warehoufe, &c. immediately produces a fhower of water to extinguish it.

2. A ciftern, with an apparatus of a different kind, by means of which a fhower of water is brought down to quench fire in a chimney, on fimply pulling a wire over the mantle-piece.

3. A gridiron, which preferves the chimney from danger of fire, and (with the additional advantage of favoury cookery) faves the meat from being finged or fmoked.

4. A prefervative lantern for nurferies, ftables, &c. faftened with a small padlock, which, by means of a bit of paper, is effectually fecured against being opened without certain detection. It is applicable to all the purpotes of a common padlock, and may, by the aid of a simple contrivance, be fattened in a moment, and without injury, to the key-hole of a drawer or door, fo that neither key nor pick-lock can be put into the hole without difcovery. By another fimple contrivance, it will prevent fraudulent exchanges of articles fent by carriers, or purchased at market.

5. A fire-cloak, to extinguish fire in a lady's clothes, or protect a perfon from the flames in efcaping from a houfe on fire.

6. A foot-trap, or ftrainer for the finoke, to prevent the accumulation of foot in chimneys.

7. A foot-trap register-ftove, of twodifferent kinds; alfo a register-top, with a foot-trap, to be fixed on a common ftove.

8. A water-trough in the back of a chimney (kept conftantly full by means of a ball-cock) to catch foot, and prevent the danger of fire.

9. An elegant japanned fire-fcreen, anfwering alfo the purposes of a fire guard, a chimney-board, and an extinguither for a chunney on fire.

10. A chimney-damper, to extinguith fire in a chimney by intercepting the draught of air.

11. A water-candlestick and nightlight, both of improved construction.
