STOVE AND FURNACE PIPE ELBOW Filed June 15, 1935 INVENTOR Hu/c/vhson Pa f/enson ATTORNEYS Patented Mar. 16, 1937 UNITED STATES PATENT OFFICE 2,074,023 STOVE AND FURNACE PIPE ELBOW Hutchinson Patterson,

1 Claim.
the pipes is aiforded.
A further object of my invention is the provision of means for connecting the collar or With these vention consists in the novel construction, ar-
which drawing:
Figure 1 is a fragmentary top plan view of a stove or furnace pipe elbow constructed in accordance with my invention.
Figure 2 is a side elevation of my improved elbow, the cover being shown raised from the sleeve or collar.
Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates a stove or furnace pipe elbow constructed in accordance with my invention, and the same includes the elbow body 5 having the horizontal leg or branch 6, and the vertical leg or branch I. This part of the elbow is of the usual or any preferred character, and I incorporate with this part, a sleeve or collar 8.
The body5 of the elbow, intermediate the branches 6 and 1, is provided with an enlarged opening, and the lower end of the collar 8 is provided with an annular retaining flange 9, which is and extends a considerable distance above the elbow.
Normally, the sleeve or collar 8 is closed by a removable cover It), which is adapted to fit over the said sleeve or collar. The skirt ll of the cover carries inwardly directed pins l2, which are adapted to fit in oppositely directed inclined slots l3 formed in the upper edge of the sleeve or collar. Obviously, by giving the cover I I] a way the cover is rotated.
The diameter of the sleeve able 1n accordance with the II] is removed, easy access is had into the pipe for the desired type of cleaning devices.
I am aware that prior to my invention numerous types of furnace and stove-pipe elbows have been manufactured, and that attempts have been made to provide an elbow with a clean-out opening. However, as far as I am aware, I am the first to use a sheet metal sleeve pending collar normally of the sleeve.
