For improvements in the Many-charabered cylinder Fire Arms; Mighill 

 Nutting, Portland, Maine, April 25. 



For a Horse Power for propelling machinery ; James Secor, city of New 

 York, April 23. 



For an improvement in Water wheels ; John Munmia, West Alexandria" 

 Preble county, Ohio, April 28. 



Tlie variation in this wheel from some others is not of a character to render 

 particular description necessary ; the claim is to " the combination of one, 

 two, or more, tub wheels, with the wheel placed next the sehute, and the mode 

 of regulating the outlet of water, as described." 



For a machine for Mortising and Tenoning Timber; Henry Barnes, Mun- 

 son, Geauga county, Ohio, April 28. 



The subjoined claims, although they do not lead to a knowledge of the 

 particular structure of the parts, serve to show that the improvements are in 

 mere matters of arrangement, leaving the rest of the structure the same with 

 that of other mortising machines. 



" I claim the construction of the carriages with the rests, bar clamps, and 

 clamp bolts, as described. The arrangement of the lever and wedge for 

 throwing the pinion out of gear, with the racks, as described. The method 

 of connecting the pulley with the piston shaft by the spring, for allowing the 

 pulley to turn on the shaft as the cutting tool enters the wood." 



For an improvement in the Saw Mill ; James Secor, city of New York, 

 April 2S. 



The claims are to a mode of feeding the carriage, and to a connecting lever 

 for giving motion to the saw gate. The arrangements in this mill are such as 

 to render it portable, and to adapt it to its being driven by horse, or other 

 power, applicable to such mills. The saw frame is to be worked up and down 

 by means of a lever beam, operated by a crank on the fly wheel, and there is, 

 as the claim indicates, some novelty in the mode of feeding. 



For improvc-nicnis in the Machinery for making Brooms, Brushes, Mops, 

 &c.; John M. Spooner, Belchertown, Hampshire county, Massachusetts, 

 April 28. 



For a Churn ; Joshua G. Pike, Lisbon, St. Lawrence county, New York, 

 April 28. 



For an improved mode of forming Kilns for making Charcoal ; Michael 

 Carroll, Tellico Plains, Monroe county, Tennessee, April 28. 



For a Hinge for Doors, denominated the helical spring joint hinge ; D. 

 A. Hoyt, and P. W. Bulkley, Danbury, Fairfield county, Connecticut, 

 April 28. 



This hinge is to operate as a door spring, and for this purpose it is so con- 

 structed that instead of the middle knuckles of the hinge, a helical spring 

 surrounds the joint pin, the two ends being so attached as to cause the hinge 

 to close by the elastic force of the spring. Two portions of tlic hinge may, 

 if desired, be so provided with helical springs ; these may be made of brass 

 wire, and they have a very neat appearance. The claim is to " the coiling of 

 a spring' around the joint pin of door, or other hinges, in the manner set 

 forth, such tension being given to said springs as shall cause them to close a 

 door or other hinged article to which they may be applied ; said hinge being 

 constructed substantially in the manner set forth." 



MISCELLANEA. 



Tlie Uimii Plale-Glass Cumpamj's Wurks. — On Thursday, the lOlh idliiuo, llic 

 du-ectors of the Union Plate-Glass Company gave a general iuviUition to shiu-cholders 

 to inspect tho company's works, at Pocket Nook, near St. Helen's , und, accordingly, 

 about thirty gentlemen went from this town by the 10 o'clock train, and were re- 

 ceived by Mr. LiiL-y. chairman of the board of directors, by other grntlcmen of the 

 directory, and by Mr. West, miinaper of the works, by whom they were conducted 

 round the various departments of the works, witnessing almost every process in the 

 art of of manufacturing plate glass, from the making and pariticatiou of the idkali, 

 and the preparation of the sand, to the last processes of polishing the glass, and 

 silvering it for the purposes of looking-glasses, &c. The works are very extensive 

 and spacious, covering an area of nine statute acres, surrounded by high walls, with a 

 handsome substantiul entrance gate of stone, at the principal entrance to the works 

 on the St. Helen's Railway. The situation could not have been better selected 

 whether tho facilities of supply of materials, or of transit of the umnufactiu'cd 

 article be considered, or the position of the works be regarded in reference to the two 

 large and opxdent towns of Manchester and Liverpool, with the gi'cat export trade of 

 that port, and the centrality of the works in the midst of so many railw.ays, which 

 for their carriages require a large supply of plate glass ; indeed, in all respects, there 

 are few finer sites in the kiugdom. Within a quarter of a mile of St. Helen's, and 

 still nearer to coal-pits; the railway running close by the worlvs on their eastern 

 side; the Satdiey navigation flowing close past the western side; and an abundant 

 supply of water obtained from a subterranean river or stream, supposed to take its 

 rise to the northttard, and locally known by the name of " Roaring Meg ;" all these 

 advantages are rarely found in such complete cd\)ibination. The water is raised from 

 " Roaring Meg " by a small steam-engine, of eight or ten horses' power, and con- 

 veyed in pipes of eigbt-incli and six-inch bore, to the ditl'erent parts of the works

British Association. — The Model Committee, appointed to superintend the exbibi- 

 tion of models at the meeting of the Jlritish Association for the -Vdvancement of 

 Science, to be held in this town on the 26di of August next, arc desirous ot receiving 

 specimens of manufacture ami works of art by the loth of that moiUh, in order that 

 they may be properly arranged and classified. — Birmimjliotn Aitrcrtibt'i:

Conflagration of the Clicltenliam Theatre. — On Friday morning, the 3d ultimo, tho 

 Cheltenham theatre was totally destroyed by fire, together with two or three small 

 houses adjoining it. The theatre was built in 180.5, by Mr. J. Watson, a coadjutor 

 of John Kemble and Mrs. Siddous, both of whom in the early part of their career had 

 ajjpeared on the Cheltenham boards. The bouse was preparing for tiie appearance 

 of Rlr. and Mrs. Yates, and Mrs. Wood, at the lime of the accident. The property, 

 w Inch is insured for 2,000/. in the I'lucnix Fire-olhce, was of the value of about 5,000/. 

 It was in the bauds of trustees f(H- the benefit of the proprietor's creditors. To such :i 

 degfec has the taste for theatricals I'allen ofl" since Lord Segi-ave and his brothers were 

 in the habit of actini;, that it is doubted if another theatre will be built at Cheltenham. 

 Photogenic Drawing.-^. — Mr. Robert Mallet has connuunicatcd to the Royal Irish 

 Academy a notice of the discovery of the property of the light enulted by incan- 

 descent coke to blacken photogenic paper ; and proposed it as a substitute for S(dar 

 light, or that from the oxy -hydrogen blowpipe with lime. One of the most injportanl 

 ajiidicatious of the pliotogenic process, as yet suggested, is its adaptation to the self- 

 ic'isteriug of long-continued insti'umental observations. Unless, however, an artifi- 

 cial light, of a simple and inexpeusive character, can be found to supply the place 

 of solar light at night, the utility of this application will be much limited. Few ar- 

 tificial lights enut enough of the ehenucal rays to act with certainty on the prepared 

 paper; while those which are known to act well, as the oxj'-bydrogcn lime light, are 

 expensive, and diliicidt to manage. A considerable time since, the author discovered 

 that the light enutted by incandescent coke, at the " Twyer " (or aperture by which 

 the blast is admitted) of a cupola or furnace for 'melting cast iron, eonti\iued the che- 

 mical rays in abundance ; and on lately trying the efl'ect of this lighten the prepared 

 paper, he found it was intensely blackened in about forty-five seconds. In the single 

 experiment made, the heat, which was considerable, was not sepai'ated from the light ; 

 hut the author purposed to make further experiments, in which this precaution will 

 be attended to. 'J'here is no diflicvdty to be apprehended in contriving an apparatus 

 tfi burn a small quantity of coke at a high temperature. A diagram of au apparatus 

 for this purpose was shown. 



EndJa's Patent Metliod of Consuming Smoke. — .A.mongst the numerous patents 

 which have lately been obtained lor plans for consuming smoke, there are noue 

 which can vie in simplicity with that invented by a Mr. Rodda ; and its eflieiency. as 

 far as it has been tried, has been uuequivocally attested by tho engineer and others 

 who have superintended the operation of the plan at Truman, Hanbury and C'o.'s 

 brewery. The method adopted is to partition of a portion of the back of a furnace 

 with tu'e-brick, so that when the coal has been coked in the fore part, it is thrust into 

 the binder division, aud the .smoke from the freshly supplied coal being compelled to 

 pass over the incandescent coked fuel, is consumed. The principal merit of this 

 invention is in its simplicity, consisting merely of a few fire-brir].s, which may be 

 placed in any furnace without expensive alteration. We shall bercafur publish a 

 full description and engravings of the plan. — Mechanics' Magazine. 



Pontypool Iron Trade. — On Tuesday, the 14tb idtimo, was started for the first 

 time, the new forge erected at Pontnewyuedd (near this town), by the Pentwyn and 

 Golynos Iron Company. The powerful engine, with all its complication of machinery, 

 tr-ains of rolls and hammers, were set in motion in the presence of a large assemblage 

 of spectators, who cheered heartily as the first bar was rolled out ; and went oil' in a 

 manner that reflected the highest credit on the engine mauuliicturers who erected it 

 (Messrs. Otway and Winnington, of Staflbrdshire) and nuicb to the satisfaction aud 

 pleasure of those proprietors who were present on the occasion. This large work 

 being so near to the town, promises greatadvantages to the tradesmen of Pontypool. —

Sir James Anderson's Steam Carriages The indefatigable exertions and untiring 



energj' of this scientific gentleman, have at length been crowned with couqdete suc- 

 cess. The first of these carriages, built for the English Steam Coach Company, lias 

 been despatched to London via Dublin. Previous to its starling, it underwent re- 

 pe.ateil experimental trials of its power and capabilities. Too much praise cannot be 

 awarded to Sir James Anderson for his perseverance, despite of every obstacle, uni- 

 versally believed by his fiiends that " he was hoping against all hope." The ultimate 

 satisfactory accomplishment of his object must, independently of the great pecuniary 

 gaius which will certainly result from it, prove a rich reward for all Ids labours ami 

 disappointments, aud ought to bold out encouragement to our scientific countrymen, 

 not to be deterred by tho most apparently stupendous tUlficulties, which, as in this 

 case, may be overcome by zeal aud industry — Cork Standard. 



The Atmospheric Railroad. — A second series of experiments, with models, upon a 

 modelled railroad, of Clegg's atmospheric principle of propelling carriages by meansof 

 exhausting a tube laid downinthe line of road to be traversed, oftbe air contained in it, 

 aud creating a vacuiun, was made on Tuesday forenoon at the iron works of Messrs. 

 Samuda, Southwark. The tube being exhausted by means of an air pump, the models, 

 the leading one having a piston whicli forced open the valve of the tube, proceeded at 

 a rate of extreme velocity along the line, a distance of thirty or forty yards, the 

 ascent being one foot in thirty. The models were heavily laden, each carryiug a 

 couple of persons, and upwards of 1.5 cwt. of balhist being disposed over the whole. 

 There were present several members of Parliament, and railway directors, enguieers, 

 &c. The machinery performed to perfection, and gave general satisfaction. The 

 advantages that this system proposes, both for the public and the railroad proprietors, 

 are very obvious — cheapness, security, speed, and no danger of explosion : it is, iu 

 fact, free from those disadvantages which the present system iu operation abounds in.

LAW PROCEEDINGS. 



CLARIDGE'S PATENT ASPHALTE. 



VICE-CHANCELLOK'S COURT, WEDNESDAY, MAY 8. 



Claridf/c V. Loitis Latrade. 

 Mr. Wigrani, IMr, Richards, and Mr. Chichester, moved to dissolve au 

 injunction obtained upon notice on the 13th of February, whereby the 

 defendant was restrained from forming a mastic cement or composition by 

 means of heat, of asphultc or asphaltic rock from Val de Travcrs, or any 

 other natural couiposition consisting principally of lime aud bitumen, with 

 a small portion ot aqueous or other matter, by whatever name such compound 

 might be called or known, with bitumen, or mineral, or other pilch, and 

 from laying down in Oxford-street or elsewhere any blocks formed of such 

 mastic, cement, or composition, and granite or other stone, or with any
