DAVID venmhr, or MONROE, IOWA, ASSIGNOR FOR ONE-HALF T0 LEVI FISHER.
- Letters Patent No. 103,943, dated June 7, 187i).
To all whom it may concern:
Beitkn'own that I, DAVID V. THRIFT, of Mon- -roe, in the county of Jasper and in theState of Iowa, have invented certain new and useful Improvements in Ventilators for Stove-Pipes, clare that. the. following is a full, clear, and exact description thereof, reference being had "to the accompanying'drawing and to theletters of reference marked thereon making a part of this-specification.
, The nature of my invention consists in the con- .struction and general arrangementof a ventilator for stove-pipes, as will be hereinafter fully set forth. In order to enable others skilled in the art to which my invention appertains to make an'dnse the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a'longitudinal vertical section, and
Figure 2 a'plan view of my ventilator.
A represents a cylinder, .of the required size, with a perforated head-piece, B, at one en To this head-piece is attached a smaller cylinder, 0, atasuitable distance from the outside cylinder, and of the same. length. y The inside cylinder'C is perforated with large holes, a ((11, around its center, and smaller ones, I) b, at both en s.
D represents a double cone, made by' attaching the small ends of two cones together, giving it an hourglass shape. g p
This double cone has'a flange, d. on one end to keep it in place.
The hour-glass cone D is inserted within the inside cylinder '0, the flange d'resting on top thereof, as shown in fig. 1,-and the ventilator is ready for-use.
By this. arrangement the stove-pipe can only come in contact with the center or contracted portion of said cone, and, when the cone is placed in position, its peculiar construction forms an air-chamber betweenit and the inner cylinder 0. The larger perforations a a in said cylinder, being directly opposite the contraction of the cones, admit a continual current of cold air into the chamber formed, thereby keeping the part and d9 hereby deof the cone in contact with the stove-pipe so cool'as to make it impossible for a fire to originate from an over-heated ventilator.
There being but one head-piece to the ventilator, and the open end being turned down, prevents anything from collecting within the ventilatorwhich might obstruct a free'circulation of air within.
There being a. free circulation of air in the outer chamber, and from there through the perforations in the inner cylinder to the inner chamber, makes a complete and safe ventilator under all circumstances. This ventilator is to be made of tin, or other suitable' material, by double-seaming and pinning, with out the'nse of solder, making it less liable to get out of orde1'.-
Having thus fully described my invention, What I claim as new, and desire tosecure by Letters Patent, is-'- 1. A stove-pipe ventilator, having one perforated head-piece, and a perforated inside cylinder, substane' tially as herein set forth.
2; The double cone D, constructed as described, so
as to fit within the inner cylinder 0, thereby forming an air-chamber, and more perfectly holding and securing a stove-pipe, substantially as setforth.
3. An inner air-chamber, formed by and between a double cone and inside cylinder of a stove-pipe vent-ilator, in combination with suitable perforations. in said inner cylinder for admitting .air into the air-chamber, substantially as herein set forth.
4. The combinationof the outside cylinder A, headpiece B, inside perforated cylinder 0, and the double cone D, with the air-chamber formed between said inside cylinder and cone, all substantially as and for the purposes herein set forth.-
In testimony that I claim the foregoing, I have-hereunto set my hand this 10th day of February, 1870.
DAVID V. THRIFT.
