    Gurney s Improvements in Apparatus for liaising or Generating Steam. NOW KNOW YE, that in compliance with the said proviso, I, the said Goldsworthy Gurney, do hereby declare that the nature of my said Invention, and the manner in which the same is to be performed, are particularly described and ascertained in the following description thereof (that is to say) :— 5 My improvements are for the most part applicable to, or are improvements in, the construction of such boilers or vessels for raising or generating steam as contain but small quantities of water compared with the surface exposed to the heat. My first improvement is more particularly applicable to such boilers as 10 are composed of a series of small cylindrical tubes or pipes so combined and united together as to form a close vessel or receptacle to contain the water from which steam is to be raised or generated by the heat of the fire and flame applied against the external surfaces of such pipes or tubes; and my said improvement consists in the application of wire, or of wire gauze or cloth 15 woven of metallic wires and cut into narrow bands or slips, or fillets, which are to be wrapped around or interwoven amongst the said tubes, in such manner as to increase the surface exposed to the heat, and also to present to the fire as many as possible of those ends or points which are formed in cutting and dividing the wire cloth into slips as aforesaid, in order that such wires and 20 metallic points may collect and conduct the heat of the fire through the metal to the water contained in the said tubes, so as to increase the effect of raising or generating steam therefrom. My second improvement is a mode of arranging and combining the pipes or small cylindrical tubes which are to form a steam boiler, in the 25 manner represented in the Drawing N° 1 hereunto annexed, wherein Figure 1 is a longtidunical section or elevation, and Figure 2 a transverse or end section of a boiler constructed with tubes arranged according to my improve¬ ments. A, A, B, B, are the small cylindrical tubes which are bended so as to cross each other, and form double loops in the manner of a figure 30 of 8, as shewn in Figure 2 ; a number of such curved tubes are arranged one behind the other, in parallel vertical planes, being all united to two large horizontal tubes D and E, one at the bottom, and the other at the top of the boiler; so that the internal capacities of all the tubes are combined to form one vessel or receptacle for the water from which steam 35 is to be raised or regenerated. The contained water communicates freely within all the small tubes A, A, B, B, by means of the large horizontal tube D, which is common to them all; and the steam which is generated within the small tubes rises up therein and collects in the top of the
