volving with it, is placed a drum, c, which works, bymeans of a leather belt, the pulley d attached to themoving platform; the pulley d is fixed on the shaft e,upon which are placed the bevil-wheels, which impart thethreefold motion to the crane. The bevil-wheels //, whichrevolve on the shaft, are made so as to turn the bevil-wheel g, by means of the clutch-box h, which is attachedto the shaft; so that by withdrawing the clutch-box fromone of the bevil-wheels, and putting it in gear with theother, the motion of the bevil-wheel, g, is reversed, andwhen the clutch-box is out of gear, the bevil-wheel g isstationary. The bevil-wheel g is fastened upon the smallshaft i, to the other end of which is attached the pinion i,which works the spur-wheel fixed to the roller-wheel k,and imparts the longitudinal motion to the whole plat-form. As the platform would otherwise move away fromthe drum c, which communicates the motion, it is madeto slide freely upon the shaft, and being attached to themoving platform by means of the rod l, it always pre-serves its relative position with regard to the pulley d.The difficulty of making the drum pass over the numer-ous brackets that a long shaft must necessarily have tosupport it, is overcome by making the brackets swing ona centre, so that when the drum c, protected by theguard n, comes in contact with one of the brackets 6 6, ityields, as shown in fig. 1, and allows the drum to passover it. Immediately it has so passed, the weight of thelower extremity of the bracket causes it to resume itsposition, and the machine passes on to the next bracket,where the operation is repeated. In order to prevent theshock that would be felt in putting in motion so heavya body as a travelling crane of 50 feet span, carrying, inaddition to its own weight, a load of three or four tons,a friction-roller, o, is made to press upon the leather beltthat passes round the drum c and the pulley d, so thatbefore putting the machine in gear the friction-roller israised; the machine is then put in gear, and the friction-roller gradually lowered. The momentary slipping ofthe belt round the pulley d, when the weight of thefriction-roller is only partially resting upon it, causes themachine to move forward with an easy motion, and,directly it is under way, the friction-roller is allowed tobear with the whole of its weight, and the crane thenmoves forward with its load at its usual speed of 100 feetin 45 seconds. The hoisting motion is obtained by com-municating the power through the bevil-wheels q q, andthe shaft r, to the barrel s, round which the chain revolves.In order to render the hoisting motion independent of thetransverse motion, the hoisting chain passes from thebarrel round which it is coiled to the truck t, and afterpassing over the pulley n, under the snatch-block v, andover the pulley to, it is finally attached to the point x, atthe extreme end of the platform. To hoist a weight,therefore, it is merely necessary that the handle y, whichcommunicates with the clutch-box z, should be moved afew inches.

The transverse motion is imparted to the load by meansof the barrel 'a, which is worked from the shaft e, by thebevil-wheels ’b V, and clutch-box ’c, in the same manneras the longitudinal and the hoisting motions. Twochains are attached to the barrel, in such a way that onewinds when the other unwinds. One of these chains isattached to the small truck t, at ’d, and the other iscarried round the pulley 'e, and fastened to the truck at'/, so that by alternately putting the clutch-box 'c in gearwith one or other of the bevil-wheels '6 '6, by means ofthe handle ’g, the truck, and with it the load, is movedbackwards and forwards along the platform at rightangles with the motion of the platform itself.

Each of the above, the longitudinal, the transverse,and the hoisting motions, can be used independently ofeither of the others; or any two of the motions may beused in combination; or the whole three may be usedsimultaneously. For instance, at the same time that aweight attached to the hook A 1 is being raised from theground by the barrel s, the track t, and consequently theload suspended on the chain, may be moved in the direc-tion 'i or 'j, at the same time that the whole platform maybe moving in a longitudinal direction.

[A waggon of heavy merchandize taken to a crane canbe unloaded and placed in a road-waggon by three men inone hour: without the crane, double the number of menworking a whole day would be required to do the samework. Cranes that can be moved to the waggons are oftenadvantageous.—S. C.]

436 Tebay, J., Aldine Chambers, Paternoster Row —Inventor and Manufacturer.

Patent water-meter.

438 Fell, Richard, 33 Nicholas Lane —Inventor.

Sea-water regenerator, to supply pure fresh water fromsalt or sea water, iu whatever situation it may be required.For shipping purposes it supersedes the necessity of em-barking water. The expense is comparatively trifling.

Patent self-cleansing filter; a peculiar feature consistsin its being applicable either for a large reservoir or for aportable or house filter.

New motive power, intended to supersede the use of allsteam locomotives, by introducing compressed air to propelcarriages upon railways, by maintaining a uniform pres-sure or force throughout the line, and having at all timesa perfect command of the engine or carriages.

Preservator; for obviating the necessity of bottling allkinds of liquors, requiring preservation from the atmo-sphere. By this machine, wines, spirits, stout, &c., canbe kept on draught, and not only retain their full flavour,but they can also be removed from one vessel to anotherwithout being exposed to the atmosphere.

440 Siebe, A, 5 Denmark Street, Soho —Inventor.Improved self-pressure cock for steam-boilers.

444 Fletcher, Thomas, 161 Westgate Street, Gloucester—Inventor and Manufacturer.

Improved slide-tap apparatus for supplying fire-engineswith water from the street plugs. It opens a two-inchwaterway through the slide, and having a curved neck,it offers no obstruction to the passage of the waterwhen in use. Double connecting branch for the supplyof two engines. Improved slide-tap to be attached tohose and swan’s neck at the engine, so as to enable thefireman in attendance at the engine to shut off the waterwhen desired.
