Bryan Corcoran Ltd, Mark Lane & Backchurch Lane
The DUKE OF SOMERSET (in the Absence of the EARL OF HARROWBY) in the Chair Mr Bryan Corcoran Is called in; and examined as follows: What is your profession?—A Bushel maker, as well as a manufacturer of Mill stones for Millers. How do you ascertain the correctness of the Bushel which you make?—By the Standard at Guildhall in London; our Measures are prepared in the neatest and safest manner we can, sufficiently drawing out all the moisture; the sap is completely extracted, as we suppose, and it is almost immoveable. After what model is it made?—Round, with an even bottom, according to what it is; if it is for a Farmer, we make it Sixteen inches diameter and the depth is regulated accordingly to hold a bushel, about Twelve inches deep; if it is for a Corn Merchant, we generally go by the Standard, Eighteen inches and Half wide and Eight inches deep, which is as the Act of Parliament expresses it and is called a Meter bushel. When you have made a Bushel as accurately as you can by Measurement, how do you ascertain its contents?—No otherwise than by comparing it with the Standard at Guildhall, the same as when we take a copy of the Standard in the Exchequer for a Corporate Body, we endeavour to take it as accurately as we can from the copy which is in the Exchequer; but which is not correct by any means. Do you verify the accuracy of that Bushel which has been made by Measurement by trying what quantity of liquid it will contain?—Yes; if it contains equal to the other we do not go into the minutiae what the Quantity is, but we make it the same as the Standard at Guildhall or the Exchequer. You do not weigh the water?—No, never. There is one other Bushel we make for the Granary Keepers and the Wharfingers, and those who turn over so much grain in the port of London, which is Two inches deeper, but will hold the same in capacity; both correspond, or so nearly as to pass between Buyer and Seller; this narrow Bushel or Drum bushel is for the convenience of the workmen, that one man can turn over with agility and practice from sixty to seventy quarters in one hour, which cannot be done by the wide Bushel; that must be worked double-handed; but with the narrow Bushel one man can do it; that is for the Granary keepers in the port of London. Do you uniformly try the accuracy of your Bushel by filling it with water, and ascertaining the quantity of water it holds?—Always; from practice we know directly by our rule what the Bushel is, within perhaps the thickness of a sheet of paper or two; when these are prepared in the dry manner I have spoken of, we take them to the Guildhall of London; we always make them large enough, so that we can take down the superfluity, and that it may be finished afterwards; this is done before the iron is put on, before it is hooped; our wooden bushels are hooped with Iron: we always take care there shall be plenty of measure, then the Sealer whose business it is to seal them, the officer of the corporation, seals them with a brand, burnt on the inside and the opposite side; without that voucher we do not sell them. When you have made a Bushel as accurately as you can by Measurement, and come to try it by its contents in water, do you frequently find that it requires a good deal of correction?— Sometimes very little; the water swells it a little, but it comes very soon to, while we are finishing it. May not the measurement of a Bushel be made correctly without ascertaining its contents with water?—I cannot say; we never send it out without. When you go to try it at Guildhall do you fill the Guildhall bushel with water?—Yes, the Guildhall Bushel is filled with water, and in as careful a manner as we can we take it out; there are Three wedges like a tripod, so that we can regulate it with the greatest nicety; the water is taken out of the Guildhall measure and put into the other and back again; we then mark it on the inside with a point, and reduce it down to that point, to equal where the water was, and this same water is restored again into the Guildhall Standard; that is the practice with us. Is not there a penalty on your selling measures without their being stamped?—I have consulted the Act, but have not found that there was a penalty. The Mark is put near the top?—Yes, the Bushel cannot be reduced afterwards without infringing on the burnt seal. You have said that the Measure at the Exchequer is faulty, and different from the measure at Guildhall, have you not?—Yes, it is; the Act of Parliament refers to its being Eighteen inches and a half diameter and Eight inches deep; it is not so at the Exchequer, but goes tapering to the bottom, and has been cut out to enlarge it at some former time, and the lip of it is very unequal; some parts are up and some parts down; it is a very unequal measure, and very unfit to be called a Standard for any thing. Has that happened by wearing?—It never was good; I have sent off, perhaps, more copies to Corporate Bodies than any one; but I dare not say that they are accurately like one another. Are the copies sent from the pattern in Guildhall or the Exchequer Standards from the Exchequer?—Wooden ones from Guildhall. Do you know the difference between the two?—They are made as nearly as the human hand can make them; I believe in the time that Mr. Alderman Combe was Mayor of London, he took an active part in it, and there were pains taken to make them alike, because prior to this the Guildhall Standard, being correct and circular, held more; it was a better made Bushel, and held what it ought; but I believe at that time it was reduced a trifle merely to correspond with the Exchequer Standard. They are both Metal measures?—Yes, Brass. If you, as a Bushel maker, were to have assigned to you the task of making a Brass and perfect Measure, do you suppose that Measure could be deranged again?—Never, but by the greatest violence; those I have made have been, perhaps, at the lip, half an inch thick very nearly, and a corresponding thickness all round, and at the bottom, with cast handles to it complete; there is nothing can ever destroy the Standard if it is done properly. Do the Corporations frequently send up their copies to have them again verified?—No, there is no occasion; for a Standard which is once turned out properly can never vary; the principal thing we want is to have a proper Standard at the Exchequer, or wherever it may be directed; then there would be no difficulty: we suppose that the Exchequer is the place where the Standard should be that is identified as the Standard of England. The Measures made from the Exchequer Standard, you say, do not always coincide with each other?—No, it is so imperfect that they cannot be made to coincide. The Standards made after the Guildhall measure must all coincide?—There are none made from the Guildhall measure, only from the Exchequer; hence comes the inequality. If there were a new one, its being made smaller at the top than at the bottom, would give us a facility in ascertaining the precise quantity. The Witness is directed to withdraw. |
SMITH'S FLOUR DRESSING MACHINE Sir, —A few days ago I had occasion to call at the very extensive flour mills of Mr. Edward Hudson of Leeds, called the King's Old Mills, in which are 40 pairs of stones, besides a considerable number of presses for extracting the oil from rape and linseed. Among the many ingenious contrivances for facilitating the work, my attention was particularly taken up with a patent Flour Dressing Machine, the use of which must be of very extensive advantage to the miller. The patent was obtained by an ingenious man of the name of Smith, who resides in Bradford in Yorkshire; he has not introduced the machine many miles from his own town; and although it is the best piece of machinery of the kind I ever saw, I fear that for want of its merits being known to the trade, it will remain in oblivion. The great advantage this machine possesses over any other I have met with, is its being constructed entirely of iron and brass, so that it is not subject to warp and get out of truth, or to wear out, like those made of wood. It has also an appendage, which I never saw in any other flour dressing machines. Down the outside of the cylinder there is a round iron shaft, on which are fixed round brushes—which shaft is constantly revolving and brushes the flour out of the wire, while a slow motion given to the cylinder presents the surface of it to the brushes. When wheat is damp, a very great advantage will be found in keeping the wire constantly clear. By a contrivance in turning two or three screw nuts connected with the inner brushes, the arms can be lengthened or shortened, so as to make them press more ir less on the wire. The whole is considered a cheap piece of machinery, and likely to be very durable. I am informed that one of these valuable machines may be seen at the warehouse of Mr. Bryan Corcoran, No. 36, Mark-lane, London. By inserting this in your valuable Magazine, you will do a great service to millers, and, I hope, to the ingenious inventor of the patent flour dressing machine. Your obedient servant, W. R— C—. |

Messrs.
Corcoran, Witt, and Co., Stand No. 40, exhibited a grinding mill of
peculiar construction for producing semolina. The machine consists of a
circular iron pedestal carrying a bedstone built of French burr, with
spaces left between them. In these spaces are inserted cast iron frames
covered with wire gauze, the object being to let the flour and semolina
fall through the wire sieves as soon as they are separated from the
branny particles, and thus nothing but the bran comes out at the
circumference of the stone. Beneath the bedstone revolving drums are
placed nmning round on a table to collect and distribute the flour and
semolina; hammers are also provided to jar the sieves at intervals to
prevent their choking. Samples of semolina made by this machine were
exhibited, and appeared to be very good and clean. Messrs. Corcoran and
Witt also exhibited porcelain roller mills, the champion middlings
purifier, millstones, and other articles connected with mill
furnishing. |
