UNITED STATES PATENT OFFICE.
JOHN PETTINGELL, OE LOVELL, MASSACHUSETTS.
IRON CHIMNEY-TOP.
Specification of Letters Patent No. 30,345, dated October 9, 1860.
T 0 all whom it may concern:
Be it known that I, JOHN PETTINGELL, of Lowell, in the count-y of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Iron Chimney-Tops; and I do hereby declare that the following is a full and exact description thereof, referencebeing had to the accompanying drawings and to the letters of reference marked thereon.
Figure 1, represents a front elevation of a chimney with one of my improved iron tops attached. Fig. 2, is a vertical section, showing the form of the top and manner of attaching the same to the chimney.
Similar letters of reference in each figure refer to like parts.
A, A, represent the brick work of the chimney.
B, is the flue. To suit the different sizes of flues, I have various patterns; of sizes to correspond.
C, is the iron top, the distinctive features of which are as follows: is an inclined plate surrounding the flue, and placed at such an angle as will give an upward tendency to the wind, no matter from what point it comes. To make this upward tendency of the wind more certain, I project Z)) the perimeter of the flue, above the inclined plate (a), so that after the wind has had an upward tendency given to it by the inclined plate it shall be guided more directly upward by the projecting rim (5) and by this action insuring a good draft to the fine of the chimney. (c) is the lower edge of the iron top and is intended to fall below the lower edge of a projecting course of brick, so as to afford a dripping edge from which all water not shed by the inclined plate shall drop clear of the chimney. ((Z) is a continuation downward of the projecting rim (6), the object of which is to bind together the brick work which is between it and the lower rim and when this is done, to form a ground to which to plaster to, the inside of the flue, thus making a smooth, straight fine up to its very outlet.
The molding (6) may be varied at pleasure to suit the taste of the individual or the style of architecture to which it is to belong.
I do not intend to confine myself to the kind of metal here named, but may make it of any other, while I retain substantially the same form.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
The construction of the chimney top with the inclined plate a, to direct the air upward, the rim 6, to assist the draft, the rim d, to bind the brick work between it and the lower rim 0, and the molding 6, to connect the said lower rim 0, with the plate a, the said molding being joined to the plate a little inside of the edge thereof, so as to leave a dripping edge, the whole being intended to be cast of metal in one piece, all as herein shown and described.
In witness whereof I have hereunto set my signature this sixth day of March in the year of our Lord eighteen hundred and sixty.
JOHN PETTINGELL. In presence of- S. B. FRIZELL, O. E. CUsHINe.
