    HORNED ■2 A.D. 1845.—N° 10,915. Ewart's Improvements in the Manufacture of Chimney Pots.__ the manner in which the same is to be performed, are fully described and ascertained in and by the following statement thereof, that is to say The Invention consists of constructing chimney pots in such manner t at each pot consists of a double tube, one portion sliding upon the other, and capable of being .fixed at any desired height by the aid of thumb-screws and 5 nuts, or by other convenient means. The material of which I prefer to con¬ struct them is zinc, which is at once the most durable, cheap, and light. The advantages of this contrivance are very great; it gives the power of increasing at any time the draft of a chimney by increasing its height. Having thus described the nature of my Invention, I would have it under- 10 stood that the shapes of chimney pots may be varied when made according to my Invention; what I claim is, the mode herein described of constructing chimney pots, each composed of two parts or tubes, one sliding over the mother. In witness whereof, I, the said George Ewart, have hereunto set my 15 hand and seal, this First day of May, in the year of our Lord One thousand eight hundred and forty-six. GEORGE (us.) EWART. AND BE IT REMEMBERED, that on the First day of May, in the year of our Lord 1846, -the aforesaid George Ewart came before our said Lady >20 the Queen in Her Chancery, and acknowledged the Specification aforesaid, and all and every thing therein contained and specified, in form above written.
