CHARLES HANCOCK, OF GROSVENORPLACE, ARTIST, for certain improvements in printing cotton, silk, woollen, and other stuffs. Patent dated February 8, 1842.

These improvements consist in printing cotton, silk, woollen, and other stuffs, with oil or oil-colours, without any previous preparation of the stuffs by mordants, sizes, or otherwise; and also in printing them partly with oil or oil-colours, and partly with water-colours or dischargeable resists, whereby the ordinary process of printing is greatly abridged. The following is given as "the manner in which the said improvements are to be performed."

"To obtain a suitable medium for the colours, I first mix linseed-oil, nut-oil, or other drying oil, (preferring linseed-oil, because of its drying quality, and of its retaining its fluidity at lower temperatures than most others,) and raw or burnt Turkey umber together, in the proportion of about one gallon of the oil for about every pound of the umber; and I boil this mixture over a slow fire, in an open metal pan of large area, and of sufficient depth to allow it to rise without boiling over, continuing the boiling until the mixture gives indication of having nearly parted with most of its evaporable constituents, and taking care to draw the fire before any deposition of carbon takes place, which would have a discolouring effect on the contents of the pan. When these conditions have been duly observed, the resulting product is a viscid substance, of an uniform consistency, resembling that of dissolved caoutchouc, flowing freely on the application of a slight heat, or spreading by slight mechanical pressure, and neither soiling nor running, on being brought into contact with textile fabrics or paper. Instead of completing the process at one boiling, it may be effected with less risk of failure, though more slowly, by several boilings, allowing the mixture or the oil to cool each time the fire is drawn. A metal cover may be suspended over the pan by weighted chains, or ropes passing over pulleys, so that, in the event of the inflammable gases disengaged catching fire, the cover may be instantly lowered, and the flame extinguished. When it is desirable, for any particular purpose, to have the medium of a more drying or more adhesive quality than usual, I add, as the

case may be, to the mixture or oil, when in the pan, either a little white vitriol, litharge, sugar of lead, or other drier, or a little of any suitable resin. Before the product of the boiling or boilings has become quite cold, it may be thinned down, if desired, with highly-rectified oil of turpentine, or any other sufficient solvent. In order to combine the composition or medium, the nature and preparation of which I have thus described, with any of the pigments or other matters suitable for the printing of cotton, silk, woollen, and other stuffs, the combination is best effected in vessels heated by steam, according to the mode usually adopted in colour manufactories and laboratories. When the colours are to be applied to the stuffs, it may be done without any previous preparation of the stuffs by mordants, sizes, oils, or otherwise, and by means either of cylinder printing-machines, or plates, or blocks. If the medium has been previously thinned sufficiently by oil of turpentine, or other solvent, the colours may be applied in a cold state; or, if the medium has not been so previously thinned, then, in order to make the colours flow freely, the colourtroughs, tearing-sieves, plates, and cylinders must be kept warm by steam, or some other transmitter of a gentle heat, by any of the well-known methods commonly employed for such purposes. The colours do not rest on the surface, but penetrate the body of the stuff, and this without running. Any smell imparted by the oil or turpentine may be dissipated by exposure to the air. The stuffs so printed on may be of any colour or colours."

In the processes hitherto described, it has been supposed that the figures, designs, or patterns, are to be printed with the oilcolours, but instead thereof the figures, designs, or patterns may be produced in the manner of resists, by some fugitive watercolour, gum, or paste, and an oil-colour, prepared as before directed, be made use of to produce only the general ground, the stuff being washed afterwards to discharge the resist, and then aired, as before directed, to get rid of any smell of the oil or turpentine.

THOMAS CLIVE, OF BIRMINGHAM, for certain improvements in the construction of candlesticks. Patent, dated April 7, 1842.

These improvements in candlesticks consist firstly, in the construction of a new apparatus or "push up" (as this part is commonly called) for raising the candle in the socket of the candlestick, and secondly, in the combination of this "new push up" with an elastic holder for holding a candle securely in the candlestick, and for which (in part) a patent was granted 25th April, 1839, to James Barlow, of Birmingham.

The new "push up" is composed of a

brass rack and pinion. The rack is about one sixteenth part of an inch thick, and forms an arc of about two-fifths of a circle, (except at its top and bottom ends which are complete circles,) and upon the edges of this arc, a number of teeth are cut, into which the pinion is geared. The (circular) top of this arc has a flat circular disc of metal soldered into it, and forms a base to which the cup for the candle is riveted, and in the back of this arc a spring is made by cutting away the metal from three of its sides, (leaving it suspended at the top), and then pressing it outward. The use of this spring is by pressing against the shaft of the candlestick, to prevent the rack or "push up" sliding downwards, except when actuated upon by the pinion. The rack or “push up" being now put in the shaft, the pinion is put through a hole made in each side of the shaft upon which it is supported, and it is fastened in its place by being riveted at the end. By turning round a knob with the fore-finger and thumb, the pinion revolves and moves the rack or "push up" either up or down, depending upon the way in which the knob is turned.

The "claim" is to any "push up, in which a rack and pinion is used, of whatever form and however placed," and also to the method before described as well as several others stated in the specification of “giving motion to the rack and pinion."

JOHN GEORGE BODMER, OF MANCHESTEB, for certain improvements in machinery or apparatus for cleaning, carding, roving, or spinning, cotton and other fibrous substances. Patent dated March 7, 1842.

The present improvements have reference principally to certain machines formerly patented by Mr. Bodmer, and particularly to those which were the subject of the patent of October 23, 1836.

The patentee describes, 1. An improved blower and lap-frame, by means of which he can form one single narrow lap, say of 5 inches in width, from the produce of a beater and feeding apparatus, "of the usual or any convenient width."

2. A self-acting tool or doffer, by which the sliver, or lap of a lap-frame, is cut, instead of being separated as usual by hand.

3. An "improved mechanism" for clearing, shifting, or stripping flats or top-cards. This improvement, the patentee says, he considers "of great importance, because of the simplicity and strength of the mechanism, and the improved position of the stripping-rollers, as the fibres which hang down from the cards are in a more favourable position to be taken hold of by the rollers, which may be driven by straps and pullies, or by gearing from any of the slow moving rollers of the carding-engine."

4. Some improvements in the steam cylinder clearer, consisting chiefly of a number of narrow brushes, instead of one.

5. An improved method of grinding the wire of card-cylinders, flats, &c.; that is, of keeping the wires constantly sharp and fine.

6. An improved mode of feeding the carding-engine, with the laps supplied by the improved blower and lap-frame (No. 1); the object of which is to correct the inequality ordinarily arising from the irregular spreading of the cotton at the lap-machine, by reducing the width of the cotton as spread.

7. An improved twist coil frame, the main feature of novelty in which is a change in the direction of the roving, which in the machine described forms the coil from below. 8. An improvement in the capping motion of the spinning-frame.

9. A new mode of banding or driving the spindles.

10. An improved flyer made of buffalo hide, softened in water, and bent in a mould.

And 11. Another flyer, made of two pieces of whalebone with wire bent round them, which wire again has thread wound round it, for the double purpose of securing the whalebone between the wires, and protecting the wires from rubbing against the iron or steel guide-plate.

JOHN LAMB, Of Kidderminster, MaCHINIST, for "certain improvements in engines to be worked by steam, air, gas, or vapours; which improvements are also applicable to pumps for raising or forcing water, air, and other fluids." Patent dated April 15, 1842.

The improvements which are the subject of this patent relate exclusively to the class of rotary engines, and are stated to "consist in one cylinder working inside another in a peculiar manner." The "manner" is ingenious, as well as "peculiar," but could not be explained satisfactorily without the aid of some of the eighteen drawings with which it has been found necessary to accompany the specification. Some general idea of the inventor's mode of action may be gathered from his claim, which is for "firstly, the application of an eccentric cylinder or cylinders, in combination with a stationary stop or stops; sach cylinders being capable of turning on. their own axes, and performing the motions required of them ;" and secondly, for " like arrangement of apparatus for the purpose of raising or forcing water, air, or other fluids."

The Manufacture of Watches.-A select committee of the House of Commons sat upon this subject in the year 1818, and it appears from the report that in 1796 the number of gold and silver watch cases marked in Goldsmiths'-hall amounted to 191,678; while in the year 1816 the gradual reduction had brought that number down to 102,112, exhibiting a diminution of 89,566, or nearly one-half; and it further appears from the last edition of M'Culloch's Dictionary of Commerce, that that number was reduced in 1841 to less than 100,000. In one township alone, in Lancashire, called Prescott, in which the manufacture of the movements of watches was the staple, there were in 1821, 869 families employed in handicrafts, whilst in 1831, from the manufacture of watches being utterly destroyed, that number was reduced to only 540. That which this country has lost, Switzerland has chiefly gained; and it is proved that England is, in this respect, tributary to the Continent-that every year the quantity of foreign watches sold in London and in the principal towns of the three kingdoms, is more than ten-fold the amount of those manufactured in England. This great injury to our manufactures and loss to our trade is likely speedily to have an end; a gentleman, who has devoted 20 years of his life to this subject, having made a variety of machines by which an incredible number of watches, of every variety of size, may be made in a day. By one of the machines 300 perfect plates can be produced in a day, by another the same quantity of barrels; by five machines the requisite number of centre, third, and fourth wheels (crossed, polished, and cut) with balances for 300 movements. By another 200 pinions can be cut and rounded; by another the holes are drilled, the tapping, the screwholes, the various parts in the plate are sunk, planting the depths and escapement, &c., and all with such exactness as cannot be excelled; another for the making and polishing of pivots, &c. Four other machines will be sufficient for making pivots for 30 movements a-day; and to add to these, there are 20 other machines for every description of work connected with the watch-making, and which altogether constitute a set. The inventor has submitted these machines to the scrutinising inspection of the most experienced makers of chronometers and watches in London, and not one has expressed a doubt of the work so produced being incomparably superior to that done in the usual way. Among other distinguished names in the trade we have ob served those of Mr. Barwise, Mr. Earnshaw, Mr. Hewett, Mr. Vieyres, Messrs. Frodsham and Co., with about a hundred watchmakers in the country, who, with the Duke of Hamilton and Mr. Howell (of the firm of Howell and James) at their head, are engaged in carrying out the great and national object of restoring this lost and important manufac ture to England by means that while they greatly lessen the price, will improve the quality, and entirely undersell our foreign rivals, and be very largely profitable to all parties concerned.
