    West's Improvements on Forges. by the following description thereof, reference being had to the Drawing hereunto annexed, and to the figures and letters marked thereon (that is to say) :— My Invention consists in causing water to circulate within the back of the forge in order to carry off heat therefrom, whereby the back of the forge will 5 be preserved from the prejudicial effects of the heat, as will be hereafter fully described. Description of the Drawing. Figure 1 represents a front view of a forge back, which is made hollow in order to admit of a flow of water. Figure 2 is a back view of Figure 1, by 10 which the position of the circulating pipes is shown. Figure 3 is a side view of a forge back, and Figure 4 is a side section, by which the action of the water will become more evident, the arrows in this latter Figure clearly indi¬ cating the flow of the water. In each of these Figures the same letters indicate similar parts. It will be seen that the back of the forge is made up 15 of the parts a and b, the part a being the front or part against which the fire or hot coal lies, and is consequently that part which is liable in the ordinary back to be quickly destroyed; but when constructed in such a manner as to admit of a constant flow of water against the back surface, this part a will be less predju- dicially acted on by the hot coal, owing to the heat being constantly conveyed 20 away by the circulation of the water. The part b constitutes the back part of the forge back ; these parts are put together by screws c, as shown in the various Figures, there being packing or luting at the joints in order to keep the same water-tight, d is the induction pipe, and e is the eduction pipe, which respectively lead from and to a tub or vessel containing water, which 25 is placed in any convenient situation in order that water may constantly flow to and from the hollow forge back a, b, as is clearly shown in Figure 5. I would here remark that the hollow forge back is to be set in like manner to ordinary backs of forges, and in other respects the forge is constructed as heretofore. 30 Having thus described the manner of applying my Invention, I will shortly state the way in which it acts. The heat of the fire against the part a of the back of the forge will quickly heat the water contained in the hollow forge back, the consequence of which will be that the hotter particles will rise upward and flow off by the pipe e, whilst a quantity of colder water will 35 constantly flow by the pipe d to make up for that which flows off by the pipe e, and thus will a continued circulation or flow of water take place in the hollow back of the forge, which, continually carrying off heat therefrom, will
