    Hall's Improvements in Boilers, Furnaces, I lues, $c.__ | Having fully described the objects and nature of my Inventions, and the apparatus° and machinery for putting them into operation, I will now proceed to state the extent of my claims, beginning with those relating to my improve¬ ments in apparatus for effecting the combustion of fuel and consuming smoke, which are, as I have already stated, improvements upon that part of my Patent 5 of Twentieth of February, One thousand eight hundred and forty-five, relating to “ Improvements in Boilers, Furnaces, and Flues in Consuming Fuel and Preventing Smoke.” My first claim under this head is the boiler protector, shewn by Is, Iigu 1 and 5, Sheet 1. My claim to this protector are as followI claim it, firstly, 10 when water is passed through it to the boiler from the feed pump or other apparatus used for supplying the boiler with water, as herein shewn. I Secondly, when water is passed through it from the well or other source o supply to the feeding cistern, preparatory to its being passed from thence to the boiler in the usual way. 1 Thirdly, when water is taken from one part of the boiler and passed through it to any other part of the boiler. Fourthly, when water is passed through it for supplying dye pans, bleaching pans, &c. with warm water, or for any other useful purposes. My second claim is for boilers with bottoms of an inclined shape from their 20 fronts, as shewn by Ax, Figure 2, Sheet 1, so as to answer the same purpose as the boiler protector N, Figures 1 and 5 of that Sheet, and having a cross flue in and near the front of the boiler, either branching right and left into the external side flues from a central longitudinal flue, as shewn in the Drawing, or simply connecting one external side flue with the other, being for the 25 purpose of superseding the necessity of having an external flue in front of the boiler. My third claim is for plates, of fire brick or other proper material, placed underneath the boiler protector or fronts of boilers for the purposes herein¬ before mentioned, as well as at the sides and tops of such furnaces as are 30 situated within the boiler for the same purpose. My fourth claim is for the inclined plates j,j, and j*9j*f Figures 1 and 2, Sheet 1, for the purposes herein-before mentioned. My fifth claim is for the plate Jc, Jc, shewn also by the last-mentioned Figures and Sheet. 1 My sixth claim is for the clinker shelf lined with fire brick M, as shewn also in the last-mentioned two Figures and Sheet, for the purpose of receiving the clinkers or scoria from the fire-bars, and letting them drop occasionally
