Abstract

A pipe consisting of a tee pipe of desired diameter replacing the elbow pipe joining the (wood burning) heater/stove to the exhaust pipe through the ceiling. This tee pipe will have a canister attached in a manner to allow removal after creosote and other debris is cleaned from the exhaust pipe. Said debris will fall into the canister and not enter the living area. Said debris can then be transported securely out of the living area without risk of contaminating the living area. Debris that normally falls into the traditional elbow and clogs it up will be eliminated. Thus reducing the chance of smoke of carbon monoxide from entering the living area.

BACKGROUND OF INVENTION

1. Field of the Invention

The present invention generally relates to the wood burning heater/stove industry. More Specifically, the present invention is drawn to increase the safety and ease of creosote and debris removal during and after cleaning exhaust piping.

2. Description of Related Art

Wood burning stoves are used in millions of homes each year. Over the years home fires and carbon monoxide deaths have occurred because cleaning the exhaust pipe is often not performed because the process is to messy. This invention will dramatically reduce these numbers because of its design to allow creosote to fall harmlessly into a receptacle at the bottom of the exhaust pipe. This invention also allows cleaning during heater/stove operation whereas the traditional elbow joint would clog and cause dangerous smoke and carbon monoxide to be trapped inside the living area.

SUMMARY OF INVENTION

The invention drawn herein is of a design to allow creosote buildup to be safely and cleanly removed after cleaning of the exhaust pipe walls. The canister pipe construction attached to the tee pipe construction catches the debris and stores it is a manner that precludes escape into the living area during pipe cleaning. The canister further allows debris to be detached and removed from the living area without having to transfer said debris into a transport container and thus contaminating the living area. Also, heater/stove operation is not impeded during debris removal as the smoke can safely exit the living area as usual. Safety is further achieved by the canister being attached by clamps to the tee section at all times which catches debris during normal operation and cleaning.

DETAILED DESCRIPTION

With attention drawn to FIG. 1 wherein [0012] 1 is a depiction of a metal pipe with another metal pipe 8 attached in a 90 degree angle 1 d to the first pipe to produce a tee pipe. Please note that 1 a, 1 b, 1 c depict the pipe to be smaller so as to allow the tee pipe to be joined to additional pipe and the heater/stove. The tee pipe clamp blocks 2, 10 are permanently attached to the pipe 1 at the bottom, adjacent to 1 a. These clamp blocks are constructed or manufactured so that a guide hole 2 a, 10 a is present for the other half of the clamp FIG. 2-6 a, 6 b to join with. The clamp blocks 2, 10 also have an extended portion 2 b, 10 b to prevent ring 5 a, 5 b from slipping off when the canister section is attached to the tee section.
FIG. 2 depicts another pipe of same construction as FIG. 1-[0013] 1. This pipe has handles 3 a, 3 b attached approximately two thirds up from the bottom for carrying. These handles 3 a, 3 b are of strong construction and size to allow comfortable carrying. Permanently attached at the top of FIG. 2 are the clamp blocks 6 a, 6 b which join with FIG. 1-2 a, 10 a. Movable clamp handles 4 a, 4 b move up and down to clamp and unclamp FIG. 1 to FIG. 2. Reversing this procedure allows the canister FIG. 2 to be removed. The pipe 9 of FIG. 2 is closed off at the bottom to produce a canister. The top of the pipe 9 located at 7 a is not closed off because it joins with 1 a of FIG. 1
FIG. 3 depicts a three dimensional view of FIG. 1 and FIG. 2 in relation to each other. The upper drawing joins with the lower drawing by [0014] 1 a being inserted into 7 a. Then the clamp blocks can be used to secure them together.
FIG. 4 depicts FIG. 1 in a three dimensional view and at an angle to show details. [0015]
FIG. 5 depicts FIG. 2 in a three dimensional view and at an angle to show details. [0016]

Claims

I claim:

1. This invention will safely catch creosote and other debris cleaned through the normal process from smoke exhaust pipe

2. The combination recited in claim 1, includes secure capture of said debris in a manner not to allow the debris to enter the living area.

3. The combination recited in claim 2, including that the debris captured in the canister will be transportable in said canister.

4. The combination recited in claim 3, including that the canister portion is removable to allow safe transport of said debris.

5. The combination recited in claim 4, including that the removable canister has sufficient means to keep it secure when not disconnected.

6. The tee section of the invention will have a secure means of clamping the canister section to itself in a semi-permanent manner.

7. The combination recited in 6, where in the canister section will have means of clamping itself to the tee section in a combatable and semi-permanent manner.

8. This invention will stop the debris that normally falls inside the exhaust pipe from accumulating and blocking smoke from exiting through the exhaust pipe.

9. The combination recited in claim 8, including that a non accumulation will reduce the chance that smoke and carbon monoxide from entering the living area.

10. The combination recited in 9, wherein the invention can be operated even while the heater/stove is in operation.

11. The combination recited in 9, wherein the invention will perform its function during cleaning of the exhaust pipe.
