BACK ron `FORGES vam) FURNACES. l
Specicationiofletters Patent No, 645, datedMarch- 157, 1838.
' To all whom t may concern.'
Be it known that I, Lum WILDER, of Leominster, in the county of Worcester and State of Massachusetts, have made an Improvement in the Construction of Blacksmiths Forges and of Furnaces Where the Bellows or Wind is Employed; and I do hereby declare that the following 1s a full and exact description.
The first part of the aforesaid improvement consists of aV cast iron back to be placed in the brick Work of the forge or furnace aforesaid at the place where the heat is to be raised by the blast of air. The size of the back, as I call it, must of course vary` according to the business and kind of work that is to be done. For a common blacksmiths forge, the back should be about face of which will stand nearly even with the brick work of the forge or furnace. In the back there is a 'cut or notch or square aperture from the lower edge upward into Vthe same about three inches wide and four inches high, in and through which notch or aperture the end of the tube hereafter described is inserted and passes. Said notch or aperture is not of equal size on the front and backsides of the back, but flares so as to be larger on the back side or the side toward the brick work and is so made to allow a little play or motion of said tube. The tube therefore when placed in the notch or aperture nearly lills the same in front or at `the surface of the back next the fire, but behind does not ll up the aperture by about one quarter of an inch. The reason for this construction is, that the tube, when it is desired to take it out, may be struck and moved a little so as to break the boraX or cement which may attach to the tube and back by use and is apt to join the parts firmly together. The size and dimensions of the back here stated are such as will answer well for a common blacksmiths forge. For furnace and large forges 'the back and the aperture should be proportionally larger than the size above specified. The other or remaining part of said improvement is the tube (so called) which when placed lies horizontally with its end in the said notch or aperture and projects a little beyond the front surface of the `back into the fire. In the tube which is hollow the bellows or wind pipe is suitable length for the tube. For furnaces and larger forges it may be longer. It is a single cast iron hollow tube. But in description it may be regarded as consisting of two parts-viz. the front part which is four inches by three inches which gives the dimensions of the front-or fire end of the tube and is the end which fills the notch or aperture in the back, as above described. This part is about two and one half inches of the seven which make the length fit. This part is square formed and larger than the other part of the tube. Said other part of the tube in a common blacksmiths forge, as above said, should be about four and one half inches long, may be rounded or square, or otherwise, and its thickness is not important, as it does not come to the fire, but should be strong and substantial. The bore of the tube should be tapering and the end next the bellows large enough forthe easy insertion of the bellows pipe. blacksmiths forge three of Vthese tubes will be convenient. For some uses a greater number might be useful. They differ in no respect except in the diameter ofthe bore next to the fire. For common uses of the blacksmiths forge three suitable sizes are here given-viz: No. l, diameter of thebore at the fire end of the tube five eighths of an inch; No. 2, said diameter seven eighths of an inch; No. 3, said diameter may be one inch. brick Work, or a piece of cast iron of a suitable size may be placed as the foundation, and the latter mode is believed to be the best.
The advantages to be expected from the improvement aforesaid may be briefly stated. The cast iron back will stand the fire in a common blacksmiths forge from three to five years. `The principal wear and waste is on the tube which is easily and cheaply replaced by a new one. When it is burnt out another may be substituted.v Upon the common construction, it is necessary frequently The back and tube may rest on theV For a common to repair the brick work of the forge and at Y varies, and the heat is less and the quantity of fuel is less when the smaller tube is employed. It may be unnecessary to add, vthat although the sizes, and dimensions above stated, are suitable for a commonv black-v smiths forge, yet thatthey are not the most material or the essential part of the V1mprovement for which a patent is here Claimed, but
The back and the tubes and the Y form thereof, their adaptation to each other and their `uses as aforesaid are the improvements 10 for which the inventor claims originality and seeks to secure the benet of Letters Patent. Y Y Y Leominster, Mass., Feb. 9, 1838.
