Description
A UNITED STATES FREDERICK TARRANT, OF SARATOGA SPRINGS, NEW YORK. i
IMPROVEMENT IN STOVE-PIPE THIMBLES.
Specification forming part of Letters Patent No. l 39,210, dated May 20, 1873,' application tiled March 22, 1873.
`telescopic stove-pipe thimble, composed of two sections held together by interlocking spiral beads upon their respective surfaces. The outer end of each section terminates in a circumferential iiange, so that when the thim ble has been properly inserted in the hole of the floor, `the flange of one section will bea-r against the under side and the liange of the other section against the upper side of the door. i
y Figure l is an elevation of my improved stove-pipe thimble. Fig. 2 is an axial section thereof.
The two sections of the thimble consist of tin or other sheet-metal tubes, A and B, which are respectively provided at one end with flanges, A and Bf, and with their other ends tted Within each other. Spiral beads or grooves, a and b, are formed in the surfaces of the` tubes, adapted to interlock and prevent the tubes from slipping on each other, except by revolving one or both of them. The flanges have each a short ring, a1 and b1, entering the ends of the tubes, and are secured to the latter by rivets, or in any other preferred manner. The anges project both outward and inward from the tubes, their inner diameter fitting the'stove-pipe between which and the tubes A and B an annular airspace will be formed,
holes being formed in the inwardly-projectin g portions of the fianges, as at a? and b2, to admit of a free circulation of air, as ususaL Lugs a3 and b3 are formed along the interior i i edges of the flanges for the attachment oi'` additional tubes, in case they are desired.
Ordinarily, I propose to make the thimble single-walled only, inthe manner shown in the drawing.
In applying the thmble, one of the sections 1 is inserted from the under side of the Hoor, and
the other section screwed into it from the upper side of the door until the anges are drawn tightly against the latter `upon both sides, in which position the sections ofthe thimble willbe securely held by the interlocking spiral beads, the anges making a neat finish around both ends of the aperture lined` A telescopic stove-pipe thimble, the tubes p y A and B of which are provided at. their outer ends with flanges A' and B', and have inter- 10Cking spiral beads a a-lld b, substantially as and for the purpose specile i In testimony whereof I have signed my*` name to this specili'cation in the presence of two subscribing witnesses.
FREDERICK TARRANT.
