vancinp. Tlif sjiinil-spriiitr 2S, arts on the lever '21, iiiul forces 

 tlie raek 17 down on to tlie iiins 2:i. For every liole reipiircd to 

 be punched in line witli the width of tlie plate under operation, a 

 oorrespondin^r liole must he made in a plate of the Jacijuard, 

 and an ailditional hole, marked .'iO, (see fifr. !*), is also made, into 

 which the stopiiiiii^-bar 31 enters at every stroke until the puiuh- 

 ini( he Ciim]deteil, at which time the Jacquard plate 3'2, which is 

 left blank, will push all the selertinff-bars c beyond the rams P, 

 and at the same time, by pushing the bar 31, disengage the cam- 

 shaft Q, by the mechanism to be liereafter explained, at the point 

 where the punches and the levers o, are held up, and thus will 

 allow the perforated plate to be taken out of the machine, and 

 another plate to he put into it. The stopping-bar 31, is provided 

 with a projection on its lower surface, which depresses the click- 

 lever 39, when the bar is pushed back ; the lever 33 is keyed on a 

 shaft 3t, moving in bearings at the back of the depressor; on the 

 other end of the shaft 34, is keyed the lever 35, to tlie upper end 

 of which is attached the link 3(i, connecting it vvith the elbow-lever 

 37 ; theend of the other aim of this lever is inclined, for the pui-- 

 pose of unlocking the plate R', and is provided with a stud, on 

 which is a latch 38, the tail of which comes in contact with the incline 

 on the elbow-lever 37, when it is in the position shown in dotted 

 lines in fig. 3 ; and as the wheel R revolves, the latch becomes disen- 

 gaged from the opening between the two projections cast on the said 

 wheel, at which time the cam-shaft Q, ceases to revolve. When 

 the stop))ing-bar 31 has been pushed back, it depresses the lever 

 39, and liberates the lever 33 from beliind the ])rojection on the 

 lever 39, when the spring to will pull the elbow-lever 37 into the 

 position shown in dotted lines. To the blocks h, a small shaft is 

 attached, on which are two levers, suspending by links a plate of 

 metal similar to a blank card-plate, except that the lioles for 

 the guide-pins are cut at the bottom edge. At each end of the 

 same shaft is a lever-handle, held up or down by a side-spring in 

 the ordinary way. The use of this apparatus is as follows : — 

 Should it he required to stop the machine before the plate is 

 finished, by raising the lever here referred to, the blank plate will 

 come in front of the roller, and will act the part of a blank Jacquard 

 plate, and stop the machine. 



Having now described the principal parts of the machine, we 

 shall proceed to explain the manner of its working. The plate to 

 be punched having been placed in the traversing-frame, on the 

 sides U, and V, is then pushed forward. In its progress, the first 

 pin of the series 23, passes under the inclined end of the rack 17, 

 until the first notch in the rack falls upon the pin. The driving- 

 strap being now on the fast pulley K, the machine is set to work 

 by pulling down the handle 42, keyed on the shaft 34, until the 

 lever 33 is latched by the click-lever 39 ; the elbow-lever 37 is 

 then, by the spiral-spring 40, brought into the position shown in 

 fig. 3. The latch 38 being now liberated, will, by the action of 

 the spring 41, (see fig. 1,) drop into the notch in the wheel R, the 

 first time it comes round ; the cam-shaft Q will now revolve at the 

 same speed as the shaft F, and the Jacquard-roUer /, will be 

 drawn back and made to perform one-sixth of a revolution on its 

 centres ; after which it will be advanced, and the first card of the 

 series will remove those selecting-bars for which there are no holes 

 in the Jacquard plate ; the other seleeting-bars will remain over 

 their respective rams P, which will then force down the punches 

 through the plate, by the descent of the depressor T. A little 

 before the punches have gone through the plate under operation, 

 the levers o, are made to press upon it, and are held there while 

 the punches are being withdrawn by the bar .?, which rises simul- 

 taneously with the depressor T, during one-half of its ascent. 



Whilst the depressor is continuing its ascent and descent 

 through the other half of the stroke, the roller ./' recedes, and 

 draws with it the bar m, which brings all the selectors again over 

 the punch-rams P. The roller /; while receding, having performed 

 another sixth of a revolution, will, on advancing, bring another of 

 the Jacquard plates against the selectors, and the operation 

 will be repeated until all the holes are punched in the plate under 

 operation. 



Iron Vessels. — Mr. Fowles of North Shields, suggests the following ira- 

 provenienls in the construction of iron vessels, by forming the keel and 

 kelson of plate or bar-iron in one or two breadths, from IJ to 21 inches in 

 thickness, and from 20 to 24 inches deep, and then to form the floors of 

 angle-iron in two lengths, and turn the ends of each up the side of the kelson, 

 and connect them together by rivets through the kelson from side to side. 

 The floor plates also to be in two lengths, which being rivetted to the floors, 

 the two sides of the ship will be connected together.

 FASCICULUS LX-XXIV. 



"I must have liberly 

 WUhal, as large a charter u* the winds, 

 To blow on wbom I please." 



I. In that very amusing, but slovenly and in parts rather dull 

 congeries of gossip, entitled " Nollekens and his Times," Museum 

 Smith speaks of a certain '•^ happy possesnor of some of the worvZ 

 fraijinnits of the nntii/ue hi this khigtlom, who em)>loys a mere mason 

 to put them together, and is perfectly satisfied thiuigh a right 

 foot has been most ingeniously placed upon a left leg !" Who 

 the " happy possessor" iilluded to was, I know not, but I do know 

 that, niutntix mntanili.s, the satire a))plies as forcibly, or in general 

 far more forcibly, to the stupid, and tasteless, and bungling, botch- 

 ings-up of architectural odds and ends — whether antique or me- 

 diieval, classical or ecclesiastical — into a design intended to pass as 

 an unexceptionable specimen of the particular style which is pro- 

 fessedly imitated, but generally caricatured more or less when so 

 treated, — xeeuinluni artem, but contrary to all artistic principle, 

 and not unfrequently contrary to meaning and purpose also. Would 

 that in architecture no greater blunders were ever committed than 

 that of sticking " a right foot on a left leg," — in which case the artist 

 might fairly have excused himself by swearing point blank that it 

 was not the ri</ht foot. — Our being imitators at the present day 

 might be forgiven ; but we are not so much imitators, as mere 

 copyists, incapal)le of entering into the spirit or meaning of our 

 models, — which are to us little better than blind guides, simply 

 because we ourselves ftdlow them blindly, and without the least 

 regard to widely-altered circumstances, ^^hat more may, under 

 present circumstances, be made of a style, is what we never con- 

 sider. Yet if we really studied our models, we should find — at 

 least, in all those most deserving of being studied — every part well 

 motived and adapted to the express occasion. How far we in that 

 respect imitate those who have gone before us, I leave it to the 

 impartial reader to determine for himself. 



II. In his above-mentioned book. Smith is pleased to say : " Men 

 of true taste visit a mansion onlyupon the report of its statues, busts, 

 and pictures. The architecture of a house unadorned by such pro- 

 ductions of art, would not induce the general traveller to drive 

 twenty miles out of his road, nor even five. How few allurements, 

 indeeti, would the Marquis of Lansdown's, Lord Pembroke's, Lord 

 Egremont's, Lord Farnhorough's, Sir Abraham Hume's, Mr. Peel's, 

 (now Sir Robert), and many other noble mansions have, if totally 

 destitute of their fine collections of statues and pictures 1" — No 

 doubt such would be the case, but why } — first, because there is 

 nothing whatever of architectural interest in the " noble mansions" 

 themselves ; and, secondly, because if there were, your " general 

 travellers" have very little, if any taste at all for architecture. 

 I was the other day in a house here in town, — one that I may 

 fairly call an " architectural house," which although totally " desti- 

 tiite of pictures and statues," with the exception of a bnsso-relier^o 

 by Lough, over a chimney-piece in one of the rooms, is in itself all 

 picture — as superior to Peel's as a pine-apple is to a pippin. For 

 my own part, whenever I go over a house for the first time, I have 

 neither eyes nor thought — nor if I had, 1 have not time — for any- 

 thing but the architecture itself. As to pictures and statues, any 

 dowdy house may be bedizened out with them, and still be, as a 

 house, as dowdy as ever, — a perfect cluster of C's : very convenient, 

 very comfortable, very commodious, very correct, very comme-il- 

 faut, and very (most of all) comnuni-place. 



III. In his anecdotes relative to Cosway, Nollekens' biographer 

 says that, after quitting Pall-Mall, " he (Cosway) fitted up his new 

 residence (No. 20, Stratford-place) in so picturestpie, and indeed so 

 princely a style, that I regret drawings were not made of the general 

 appearance of each apartment ; for many of the rooms were more 

 like scenes of enchantment pencilled by a poet's fancy than any 

 thing, perhaps, before displayed in a domestic habitation." If such 

 really was the case, they certainly were worthy of being delineated ; 

 yet we may be allowed to entertain some misgivings — first, because 

 such a character of the house partakes too much of the ^'glamour 

 might" of some of George Robins's advertisements; and, secondly, 

 nothing is said to corroborate it, or to give us any idea whatever 

 of those " scenes of enchantment," notwithstanding that the writer 

 could at least have done that, — have spoken of " the general appear- 

 ance of each apartment," and have so far rescued them from com- 

 plete oblivion. Instead of which, he merely goes on to astound us 

 by enumerating some of the costly articles of furniture and vert&
