ill any required pofition, cither witli its 

 tciUral (liatt in a lu)riz(jntal,a vertical, or 

 an oblique direction, yet Mr. F. gi\cs the 

 preference in mod calls to that pofition 

 ot the engine in wliich its (liaft is phiced 

 perpenrhculaily to tlie horizon. Having 

 ihevvn in wliat manner the invention is to 

 be applied as a fleam-engine, J\Ir. Flint 

 fays, that to adapt it to be worked by the 

 preifure of a column of water, inftead of 

 the elaftic force of fleam, its parts will be 

 nearly refemblingthofe already defcribed. 

 The only precaution neceli'ary is to make 

 tlie aperture of the lliaft, and of certain 

 holes defcribed, at leail one-third of that 

 cf the float. I'hen lei's accuracy will be 

 required in the packing. By connecting 

 tlie Ihaft with water, or other liquor to be 

 raifed, and applying the external force 

 to turn the machine, the water, &c. will 

 be raifed by the preffure of the atmo- 

 iphere into the circular palVage before d-e- 

 icribed, wlience it will be driven by the 

 motion of tfie float in a continued ftream 

 through the fliaft into the refeivoir. In 

 the fame manner engines for extinguifli- 

 mg hres may be conllructed. Blowing- 

 t-ngines alio for furnaces and forges may 

 be made on this ]jlan, only obferving that 

 the packings fhould be as perfect as pofii-

A-'K. WILLIAM COOKe's (CHUTE-IIOUSE, 



wiLTti.) for Ii)iproveinenls in the Con- 

 Jlruciion of Waggons, and other Car- 

 riages having mure than two Wheels. 

 Inliead of connecting the wheels with 

 tlie carriage in the ufual manner which 

 <:o.ufuies the lower or bearing parts of all 

 tiie wheels neaWv in one plane, this in- 

 > ention allows one or more pairs to have 

 conliderable play or liberty in the axis or 

 axle-tree of each pair, fo that the faid 

 axis, wlien one of tlie wheels fliall be 

 raifed or drpreifod by any obftacle or ir- 

 regularity may atfunve, various poiitions 

 out of the level, without requiring or 

 lUiuling the lied of the carriage, or any 

 appendage belonging to it, to deviate from 

 the ordinary piMition, unlcfs the wheel 

 (hall exceed the allowed limits. This is 

 (lone by the addition of an apparatus, 

 about tlie place where the axis of fuch 

 jKiir or pairs of wheels iliall be connected 

 w ith the carriage, fo that the faid parts 

 may produce oi admit the elVert of a hinge 

 or joint, by which the axisniay be allowed 

 to have either of its ends raifed or dc- 

 [ireffed, without alVeCting the carriage 

 within the limits. In I'ome cafes, INIr. 

 Cooke makes the .upper part or tcrmina- 

 liou of tlic main pin in the foiiu of a knob 



or piece of a circular figure : with rcfpect 

 to the central line of the main pm, all 

 the feciions of the knob that can be made 

 at right angles to the axis will be circu- 

 lar, but of a conical orfpherical figure, in 

 its longitudinal fection, in order that 

 when the laid knob fliall be inferted 

 within a hollow cylinder of the fame di- 

 ameter as that of' its greatefi; circular fec- 

 tiou, the faid main pin may be at liberty^ 

 to move fide-ways out of the dire6tion ot 

 the axis of the laid cylinder. The knob 

 is to be placed in a cylindrical hole in 

 the bed of tlie carriage or flying pillow, 

 or other apijendage, taking care, by 

 means of a nut, to prevent the fame from 

 coming out. 'I'lie knob or cylinder does, 

 i'l this conftruction, conftitute that part 

 of the conncciing apparatus between the 

 carriage itfelf and the axle-tree of the 

 ^\heels to which the main pin belongs. 

 The pole which fupports the lower end 

 of the main pin is fullered to have a little 

 play to the right and left, and the main 

 {)iu has a limited fpace for motion up and 

 down in the holes through which it paffes- 

 The bearing part, which is ufually circu- 

 lar, is made fomewhat prominent, and 

 circular in the upright fection, ii) as to 

 bo lowell in the middle, and to admit the 

 face of the axle-bed to fliift its place of 

 bearing according as the tilt or inclina- 

 tion of the axle-tree is greater or lefs.. 

 — This is only one of the methods de- 

 fcribed by the patentee for attaining his 

 end, he has given others in his fpecifica- 

 tion; and in order that his invention may 

 be the better uiiderllood, he obleiTes that 

 the advantages to be gained by thefe im- 

 provements, are not only that the carriage 

 itfelf is all'ecled in its pofition, by any 

 rile or depreffion of one of the wheels of 

 any pair, but alio that all the wheels are 

 conftantly kept in a llate of bearing upon, 

 the ground notwithlianding any irregula- 

 rities of the fame, and that tlie extreme 

 ftraiu of the machinery, and actual dan- 

 ger to which common can'iages are ex- 

 pofed, arc by this method obviated and 

 avoided;
