come just too late; still, even the convenience has^ils awkwardness, for 

 some people are so inconsiderate that they will be apt to ask why he held 

 back till the very last moment. They may also feel a little astonishment 

 at tl;e complete silence observed by the other architectural Professors. 

 Are we to understand it to be equivalent to consent — acquiescence in and 

 approval of what has been so virulently condemned ' If so they have been 

 wanting in generosity towards the authors and perpetrators of the scheme. 

 On the other hand, if they ac;ree with Professor Cockerell, they might, 

 ■without impropriety, have openly sided with him. Or shall we attribute 

 their silence to indiflereuce ? — or if not exactly to indifference to that dis- 

 cretion which prompts steady people to cross over the way, or turn into 

 another street where they see a fray going forward ? Even if i! was no 

 aHair of theirs, and they were fearful that the ofl'ering any opinion might 

 be considered busy-body ofticiousness, it did concern Mr. D. Burton, and 

 as he did not choose to appeal to the public when he was sure that the 

 general opinion would have strongly supported him, it may very fairly be 

 questioned whether he cares at all about what has been done to his build- 

 ing. The inference may not be very charitable, nor particularly flattering 

 to him, but it is certainly a very natural one. 



After all, houever, his Arch does not suffer more than another building 

 does, viz , the house over the way, which now looks more iusignilicaut auil 

 nndignifif-d than ever. Strange! that of two Uyafis, one thought he could 

 not make the Uuke look toe big, the other, his house look too little — and 

 too petite in style.

BRICK AND TILE MACHINE. 



Alfred Hall, of Coxsackie, iu the United States of America, brick- 

 maker, for " certain improvements in machinery or apparatus for making, 

 moulding, or manufacturing briclis, tiles, and other articles, from earthy or 

 plastic materials." — Granted October 2, 1843; Enrolled April 2, 18-16. — Re- 

 ported in Newton's London Journal. 



This invention relates to the construction of a machine as shown in 

 the engravings, Plate XVI., for making bricks, tiles, and other articles 

 from clay. Fig. I is a side view of part of a pug-mill, and the moulding ap- 

 paratus. Kg. 2 is a plan, and fig. 3 a vertical section through the centre of 

 the moulding apparatus and pug-mill, and fig 4 a front view of the moulding 

 apparatus. A is a pug-mill, set on a brick foundation B and pillar C ; in 

 the centre of the mil] is a vertical shaft b, supported upon a step at the lower 

 part, and at the upper part by a framing, to which is attached a beam for the 

 application of horse-power. On the shafts are fixed a number of horizontal 

 cutters, c, set radially, and at the lower end are 4 plates, d, set horizontally 

 in two lines at right angles to each other, and slightly inclined from the per- 

 pendicular, they extend nearly to the sides of the mill, and are for the purpose 

 of sweeping the clay, as the shaft rotates, into the chamber of the moulding 

 apparatus. 



The moulding apparatus consists of a chamber, D, with iron plate sides,/, 

 and a cast-iron grating, g, for the bottom (shown separately in fig. 5), con- 

 sisting of a square frame with cross bars forming as many compartments as 

 there are bricks or tiles to be produced at one working in the mould or box, 

 z, under the grating. Above the chamber is a shaft, h, with bearings at each 

 end in the side plates, ,/, which carries quadrants provided with segmental 

 racks, i, and the cover or pressing plate, k, extending the whole width of the 

 chamber D, for the purpose of forcing the clay into the chamber through the 

 grating g into the mould :: below. I is another shaft with bearings in the 

 side plates y, carrying 2 pinions, m, that take into the segmental racks ;, and 

 having a hand-wheel, n, keyed on to the end of the shaft, for giving motion 

 to the quadrant racks. ;; is a scraper, the whole width of the chaniber, fixed 

 on a shaft with bearings at each end in the side platesy; this scraper is for 

 cleaning off the clay from the segmental portion of the preising plate i. 



Below the chamber is the frame work, E, with an adjustable framing. F, 

 suspended thereto by 4 pins, which carry the bearing of a horizontal shaft, 

 5> ; shaft supports arms at each end, attached to the framing F, and also at 

 each end a lever, q' ; there is also a cross-bar, r, to carry the inner end of 

 the framing, F, which is attached to and forms the cast iron tables or grating, 

 », which support the moulds, :. s' are rollers for carrv'ing the mould im- 

 mediately beneath the grating of the chamber. The lower parts of the 

 framing, F, are bearings for a horizontal shaft, which carries a vibrating 

 lever, t, with another lever, w, jointed thereto, having forked branches on the 

 end in the form of a V, whioh carry a pair of guide-wheels with flanges, to, 

 running in a slot made iu the upper face of the framing F, and to the ends 

 of the Y lever, a cross bar, x, is bolted, y is a lever fixed on the end of the 

 cross-shaft for actuating the lever t and the parts connected therewith, and 

 : are moulds which are supplied to the machine by hand as they are re- 

 quired. 



The action of the improved machine is produced as follows : — Rotary mo- 

 tion being given to the vertical shaft 5, of the pug-mill, the plates d will 



force the clay through the opening e, into the chamber D ; and, supposing 

 a mould to be placed upon the rollers 9, in the position shewn at fig. 3, the 

 hand-wheel « is turned, which giving rotary motion to the pinions m, in gear 

 with the segment-racks, will bring down the pressing plate k, and force the 

 clay into the compartments of the mould. The workman then pulls down 

 the lever y (at the same time letting go the hand-wheel), which action will 

 cause the lever I to vibrate and draw forward the lever «, and with it the 

 cross-bar x. This bar, guided in its course by the wheels w, will push for- 

 ward a mould previously placed in front of it, as r>, fig. 3, and drive that 

 mould to the position of mould ., now full of clay, from under the grating g, 

 in escaping from which the superfluous clay will be removed by the inner 

 edge of the inclined side of the grating. The full mould will then arrive at 

 the position, on the framing, of the mould z^, from whence it is readv to be 

 carried to the drying ground. By throwing upward the lever y, the bar x 

 will retire to its former station, and another empty mould being placed be- 

 fore it, the same movement will be repeated after the mould last pushed 

 under the grating g is filled with clay, as before described. If, by accident, 

 any stone or other hard substance should get into the clay and stop'the proper 

 action of the moulding-machine, it is only necessary to depress the lever 7, 

 on the shaft 4, which will briug down the framing a sufficient distance for 

 the mould to be released. 



The claim is, firstly, for the general arrangement of the apparatus, as de- 

 scribed; secondly, the peculiar arrangement and construction of the knives 

 and plates for tempering the plastic composition, and forcing it out from the 

 pug-mill ; thirdly, the construction and application of an adjustable framing 

 for holding the moulds to receive the plastic composition, such framing being 

 capable of instant depression, as above explained ; fourthlv, the arrangement 

 of apparatus for placing the moulds successively under the grating g, as above 

 described and shewn in the dranings ; and lastly, the peculiar arrangement 

 of the grating g, with respect to the compartments of the moulds, wherebv 

 perfect bricks, tiles, and other similar articles are produced, as above ex- 

 plained. 



DIBBLING APPARATUS. 

 John Fuller, of Beacham Well, Norfolk, Farmer, for " improvements in 

 apparatus for solving corn and other seeds." — Granted March 5, 1846 ; En- 

 rolled September 5, 184C. 



This apparatus, formed of sheet tin, is held in the hand, and used for 

 dropping corn or other seed when dibbling, in place of the fingers. There 

 are three different apparatus described in the specification ; the annexed 

 figures shew the application of one of them. Figs. 1 and 2 are sections of 

 the apparatus taken transversely to each other ; a is a chamber in which the 

 seed is placed, b a roller with small recesses c in the circumference, of suf- 

 ficient capacity to deliver the proper quantity of seed through the hopper or 

 spout d; e is the handle,, /"a slide to be pressed down by the thumb on the 

 top, the lower end acts upon pins g on the margin of the roller b and forces 

 it round one division ; after each pressure the slide is drawn upwards by a self
