2 Claims.
My improved device relates to a chimney cap provided with means to improve the draft of the chimney and also to prevent rain from descending down the flue.
The object of my invention is to provide a chimney cap of pleasing design and so con structed to enhance the appearance of the chimney while providing an improved draft to the chimney.
A further object is to so construct the draft vents, that rain or moisture running down the interior of the cap will be deflected to the outside of the cap.
My invention will be further readily understood from the following description and claims, and from the drawing, in which latter:
Fig. l is a plan view of the chimney with my improved cap in place.
Fig. 2 is a side view of the same, and
Fig. 3 is an enlarged vertical section of the same, taken in the plane of the line 3-3 of Fig. 2.
My improved cap comprises a cast or molded tubular member ll arranged to set on top of the chimney l2, being attached thereto in any suitable manner, such as having the base of the member secured to the top of the chimney by cement or mortar.
While I have shown the cross-section of my improved cap to be circular, it may be made in other shapes without departing from the spirit of the invention, such as oval. I prefer to make the walls 14 of the cap slightly tapered and pro- Vide a series of spaced slots I5 about the periphery. These slots are angularly positioned to provide a downwardly extending path for drainage of any water that may run down the interior of the cap. It will be noted that the slots are narrower at their inner ends, as indicated at I6 to provide an intensified pressure on the air entering and passing through the slots to increase the up-draft of the chimney. I have shown three series of slots with the slots so positioned about the periphery that each series will be overlapped by the next succeeding series. Although two or more series may be employed depending on the size of the chimney.
The inner face of the wall directly above the slots is tapered as at I! and flares into the next taper as indicated at E8, between adjacent slots, whereby moisture or water will be deflected to one or the other of the slots.
The exterior of the cap may be suitably decorated or colored to provide a pleasing appearance in keeping with the design and finish of the chimney or house.
With my improved construction there are no projections on the interior of the cap tointer fere with the draft or collect soot. Air entering the slots will be projected upwardly with an intensified pressure, due to the angularity of the slots to create an up-draft in the chimney.
Many present day chimneys are made of hard brick, which does not absorb water, and consequently there is considerable leakage down the flue. With my improved cap in place all water or moisture starting down the cap is caught by the tapers l1 and directed through the slots to the outside, preventing it from running down the flue.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
l. A chimney cap comprising a molded wall, a series of spaced slots extending in spaced relation about the periphery of said wall, a second series of slots spaced below said first series of slots and offset within said cap in relation to said first named series, said slots extending upwardly and through said wall, and the inner upper edge of said slots chamfered to form interior drainage tapered faces extending upwardly from said slots and flaring into the adjacent faces.
2. A chimney cap comprising a tubular wall, spaced slots about the periphery of said wall, said slots extending upwardly and through said wall, said slots having a confined inner opening, and similar slots spaced below said first named slots and positioned to overlap said first named slots both on the inner and outer surfaces of the cap member.
