STEPHEN OCTAVE DELA'UNE, 0F RACELAND, LOUISIANA.
CHIMNEY-COWL.
Specification of Letters Patent.
Patented Apr. 2, 1918.
Application filed July 10, 1917. 1 Serial No. 179,696.
To all whom it may concern Be it known that I STEPHEN OCTAVE DE- LAUNE, a citizen of the United States, residing at Raceland, in the parish of Lafourche, State of Louisiana, have invented a new and useful Chimney-Cowl; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention relates to certain new and useful improvements in chimney cowls, and has for its object to provide a device of this character which embodies novel features of construction whereby it can be readily applied to a chimney, smok pipe, or ventilating tube, and will operate in an effective manner to prevent the wind from blow' 1g down the chimney or smoke pipe and interfering with the draft through the same.
Further objects of the invention are to provide a device of this character which can be easily and quickly placed in position or remove-d therefrom, which can be adjusted to fit the particular chimney or smoke pipe with accuracy, which will revolve freely under the action of the wind, and which is not liable to break or get out of repair.
With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.
For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of a chimney cowl constructed in accordance with the invention.
Fig. 2 is a similar view looking at the device from a position at right angles to that indicated by Fig. 1.
Fig. 3 is a vertical longitudinal sectional view through the cowl and the upper portion of the smoke stack.
Fig. 4 is a top plan view of the bracket for supporting the hood of the cowl.
Corresponding-and like parts are referred to in th following description and indicated in all the views of the drawings by the same reference characters. 7
Referring to the drawings, which illustrate one embodiment of the invention, the
The revolving hood A includes a circular top 6 and peripheral side walls 7 which extend downwardly from the edges of the top, said hood being open at the bottom thereof and adapted to telescope over the upper end of the smoke pipe. An opening or cut-away portion 8 is formed in one side of the hood A, and a vane 9 which extends diametrically across the top of the hood and projects from the sides thereof is arranged in such a relation to the cut-away portion 8 as to hold the latter on the leeward side of the smoke pipe when the wind blows.
A tubular bearing 10 projects upwardly from the center of the top 6 of the hood A and receives the before men loned vertical pivot rod 2 of the supporting frame. The vane 9 is suitably cut-away to receive the bearing sleeve 10, and a slide 11 which is mounted upon the vane is adapted to bemoved into a slot 12 in one side of the bearing sleeve 10 and engage an annular groove 13 in the pivot rod 2 to lock the sleeve against vertical movement on the pivot rod and hold the hood in position, at the same time permitting it to rotate freely about a vertical axis.
The downward bent ends 3 of the supporting arms 3 preferably have horizontally disposed anti-friction rollers 14- journaled thereon, said rollers being positioned between the clips l and collars 15. These rollers engage the depending sides 7 of the hood and prevent rattling or binding at the base of the hood. The portion of the side 7 of the hood under the opening or cut-away portion 8 thereof is split and overlapped, one
of the overlapping ends being formed with series of slots 16, while the other overlapping end is formed With a tongue 17 adapted to be inserted through any selected one of any particular chimney or smoke pipe.
Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is
1. A chimney cowl including a pivot rod, a series of supporting arms radiating from the base of the pivot rod and provided with chimney engaging means, anti-friction rollers upon the supporting arms, a hood mounted over the top of the chimney and having a cut-away portion in one side thereof, the sides of the hood telescoping over th upper end of the chimney and being engaged by the before mentioned anti-friction rollers, a bearing sleeve applied to the top of the hood and receiving the pivot rod, and a vane fitted upon the hood in position to hold the cut-away portion thereof on the leeward side of the chimney.
2. A chimney cowl including a pivot rod, a series of supporting arms radiating from the base of the pivot rod and terminating in clips adapted to engage the chimney, antifriction rollers journaled upon the arms, a hood arranged over the chimney and having a cut-away portion in one side thereof, the lower end of the hood telescoping over the upper one of the chimney and being eX- pansible so as to be brought into a proper engagement with the before mentioned rollers, a tubular bearing applied to the top of the hood and receiving the pivot rod, and a vane applied to the hood in position for holding the cut away portion thereon on the leeward side of the chimney.
3. A chimney cowl including a pivot rod, a series of supporting arms radiating from the base of the pivot rod and having the ends thereof extended downwardly and provided with clips adapted to engage the chim ney, horizontally disposed anti-friction rollers journaled upon the downwardly eX- tended ends of the supporting arms above the clips, a hood mounted over the chimney and having a cut-away port1on in one side asp thereof, the sides of the hood being slit and formed with overlapping edge portions which adjustably engage each other so that the sides of the hood can be brought into a proper engagementwith the antifriction rollers, a tubular bearing applied to the top ofthe hood and receiving the pivot rod, and vane fitted upon the hood in position to hold the cut-away portion thereof on the leeward side of the c imney.
A chimney cowl including a pivot rod having an annular groove therein, a series of supporting arms radiating from the base of the pivot rod and provided with means for engaging the chimney, a hood arranged over the top of the chimney and having a cut-away portion in one side thereof, a bearing sleeve extending upwardly from the top of the hood and receivin the pivot rod, said bearing sleeve having a slot in one side thereof, vane extending across the top of the hood and arranged to hold the cutaway portion tliereof on the leeward side of the chimney, and a locking slide mounted upon the vane and adapted to be moved into the slotted portion of the bearing sleeve for engagement with the groove of the pivot rod to hold the hood in position.
5. A chimney cowl including a pivot rod provided with an annular groove, a series of supporting arms radiating from the base of the pivot rod and terminating in clips adapted to engage the chimney, anti-friction rollers journaled upon the supporting rods, a hood mounted over the top of the chimney, said hood having a cut-away portion in one side thereof and being engaged at the lower end thereof by the before mentioned rollers, a bearing sleeve projecting upwardly from the hood and receiving the pivot rod, said bearing sleeve having a slot in one side thereof, a vane extending across the top of the hood and arranged to hold the cut-away portion thereofon the leeward side of the chimney, and a locking slide mounted upon the vans and adapted to be moved into the slotted portion of the hearing sleeve to engage the annular groove of the pivot rod and lock the hood in position.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
