High Wind Bio-Mass Cap

Abstract

The use of the High Wind Bio-Mass Cap helps with the ventilation of corn or pellet stoves, inserts, or fireplaces in a high or low wind area. You attach a High Wind Bio-Mass Cap to the end of a pellet or corn vent pipe where it terminates at a manufactures specified location. You may attach this cap as low as 12″ to the ground and it can face either horizontal or vertical. The cap increases the flow dynamic by creating a low pressure area at the exit of the vent pipe. By lowering the pressure at the end of the pellet or corn pipe it lowers the pressure on the ventilation motors of any of the units, which will possibly extend the life of the stove/units ventilation motor. Being only 12″ from the ground and facing horizontal this is the only cap that will keep a breeze from creating a possible back draft.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a product that you attach to the end of a pellet or corn appliance exhaust pipe. As air passes by the cap it lowers the pressure of the exhaust released from a corn or pellet stove or insert and pulls it from the flue from which it is attached. This idea came from having current caps which are placed on the end of a pellet or corn pipe just for a cover but do not help the draft. They do not allow you to put your stove on a very windy side of the house because the wind would flow back into all current caps. Placing the High Wind Bio-Mass Cap on the end of the pellet or corn vent would allow you to vent your stove out any side of a house “windy or not” and would help vent the stoves even on a still side of a house. This is a stainless steel cap made for a pellet or corn appliance. Corn and Pellet stoves have a 3″-4″ chimney pipe that emerges from the outside of a wall or roof. After the chimney pipe comes out far enough to match fire codes you place High Wind Bio-Mass Cap on the end. Using the design shown with 6 bars in different directions it allows the stoves to vent as well and draw exhaust much stronger than any existing corn or pellet cap currently on the market. With 3 bars facing different directions on the inside and 3 bars facing different directions on the outside it makes the slightest breeze that pass work like a vacuum. Circulating air around the end of the cap lowers the pressure of any gasses on the inside helping to draw any units exhaust. This is called the Venturi effect and came about back in the mid 1700's. With six bars the draw is strong enough it allows this cap to sit as low as 12” above the ground and face horizontally as well as vertically.

SUMMARY OF THE INVENTION

An object of the present invention is to help draft a pellet or corn stove in windy conditions. It uses the Venturi effect to draw emissions given off from a unit to the end of the flue.

Another objective of this present invention is to allow corn and pellet burners to draft easier with less power demand.

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE DRAWINGS

A venting cap apparatus in accordance with the preferred embodiment of the present invention is described with reference to FIGS. 1 to 6

FIGS. 1, 2 show the cap in a horizontal position so you can see its shape in a 2.4^th shrunk view. FIG. 1 as seen in 1A and 1B, is where the spot welds which hold the bars on to the 3-4″ round base.

FIG. 2 allows you to see how the cap has a flattened oval shaped top. The top of this cap will be in an oval shape approximately 3 times wider than it is tall making the top approximately 6″ wide. 2A shows the exterior ring which surrounds the smaller interior ring seen at 2B. Both 2A and 2B are connected to 2C which is the base. 2C is the part of the cap which fits on to an existing pellet or corn exhaust pipe.

FIG. 3 allows you to see a slanted version from the top. In FIG. 3 you can see how the top is wider than it is tall. This is a hand made version so there are screws shown at 3A this is the point where a spot weld will be placed to hold the top together.

FIG. 4 allows you to see the cap from a top down view or if sitting horizontally. You see the 6 intersecting bands on the outer surround 4A and the 6 intersecting interior bands seen inside the exterior surround at 4B

FIG. 5 is an interior view of a High Wind Bio-Mass Cap. And shows the end which is to be attached to a pellet or corn vent 5A shows how it attaches to a pellet or corn vent by screwing on for security. Where the screws are seen in 5B is where the spot welds will be in a factory produced cap.

FIG. 6 shows the basic shape from bottom up. This is the High Wind Bio-Mass cap which is attached to a pellet or corn vent to help and increase venting abilities.

Claims

I. We claim to have invented this cap made for pellet or corn venting pipes

II. Stated in I this cap fits on the end of pellet or corn pipes for ventilation purposes.

III. When attached on the outside of a pipe facing either vertical or horizontal it helps a pellet or corn unit vent by lowering the pressure inside the pipe.

IV. Like stated in III. When facing horizontal the option of a rain cover is offered.
