STOVEPIPE COLLAR AND ANCHOR Filed May 5, 1956 r Patented Dec. 14, 1937 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to fastening means for stovepipes.

' The main object is to provide means whereby a stovepipe will be securely held in an opening in a chimney wall.

Another advantage of the invention resides in the simplicity of construction, and the cheapness of manufacture.

Other objects and advantages of the invention Will become apparent from the drawing and the following description.

In the drawing:

Figure 1 is a side elevation of the device as applied to a stovepipe, the stovepipe being shown as applied to a flue opening in a chimney wall, the

wall being shown in section;

Figure 2 is a side elevation of the rings and connecting means;

Figure 3 is an elevational view of one end of the device;

Figure 4 a similar view of the opposite end thereof;

Figure 5 is a sectional detail on the line 5-5 of Figure 4;

Figure 6 is an enlarged fragmentary view showing the connecting means for the ends of the larger ring as shown in Figure 3, and

Figure 7 is a modified form of said connecting means.

80 Referring more particularly to the drawing wherein like reference characters designate corresponding parts in the different views, 10 is a chimney wall, having a flue opening H therein.

A stovepipe l2 has an elbow l3. A collar M, of

the ordinary type, is mounted on the stovepipe I2 and bears against the outer face of the wall ID.

The fastening means comprises two rings I5 and I6 and metal straps II. to connect the rings. The ring l5 has oiTset loop portions'lfl extending inwardly toward the axis of the ring as best shown in Figure 3. The ring I6 has loops l9 offset inwardly as shown at l9 and extended rearwardly as best shown in Figure 2 at I9". The straps I! are secured to the offset portions l8 by rivets 2D or by any other suitable means. The free ends of the straps H are bent around the offset portions l9 as best shown in Figure 5 after the parts are assembled as shown in Figure 1.

The larger ring I 5 has one of its ends formed in a loop 2|. The other end of the ring is offset as at 22 to allow the end to enter the loop 2|, said offset portion cooperating with the loop to form a stop as best shown in Figure 6.

A strand of wire 23, as shown in Figure 1, has one end secured to thering Hi the other end extending around the elbow l3 and tied at 24 to assist in holding the pipe l2 in the opening ll.

In Figure 7 is shown a modified means for connecting the loose ends of the ring I5.v In this form each of the ring ends is returned as shown at 25 and 26, respectively, and their extremities formed into U-shapes 21 and 28, respectively, that interengage, as shown, when the ring is completed. One of said returned portions is preferably cfiset as shown at 29.

In installing the device the ends 2| and 22 of ring it are disconnected and the ring I5 is then contracted and passed through the flue opening I I after which the ends are again connected.

The straps l'l secured to the portions !8 extend through the opening. The pipe l2 carrying the collar l4 and ring 56 is then inserted in the opening H, with the straps H on the outside of the pipe 52. The straps H are then bent about the portions l of ring it this causing the ring [5 to abut against the inner face of the chimney wall 10. The ring l6 bears against collar l4 and the tension of straps ll tends to draw portions l9 inwardly thereby causing straps H to frictionally engage pipe [2. The wire strand 23 is then se- 7 cured at one end to ring it and the opposite end is tied around elbow l3 to more securely hold the pipe l2 in flue opening ll.

It is to be understood that only the preferred embodiment of the invention is herein shown and described. Various changes and modifications can be made Without departing from the spirit and scope of the invention.

I claim as my invention:-

1. Fastening means for a stovepipe, comprising two wire rings having offset portions, metal bands secured to said offset portions and connecting the rings, one of said rings being adapted to engage in a chimney opening, the other ring being carried by a stovepipe and engaging the outer face of the chimney.

2. A device as in claim 1, one of said rings being an open ring and having one of its ends formed with a loop, and its other end ofiset to engage in said loop and to provide a stop to limit the closure of the ring.

3. A stovepipe fastener, comprising in combination, two resilient wire rings adapted to be positioned one on each side of a flue opening, corresponding offset portions in said rings adapted to be engaged by metal straps to connect said rings, and a strand of wire secured at one end to an elbow of a pipe, the opposite end of said strand engaging the nearest ring to hold the pipe in position in the flue.

ALBERTUS UPTON.
