Application April 4, 1947, Serial No. 739,429
This invention relates to a gutter circle and is more particularly directed to a circle which has its major portion of channel or U-shaped section, this portion merging into an attaching portion which is substantially fiat.
It is one object of the invention to provide a gutter circle made from a minimum amount of metal and yet one which possesses sufiicient strength to withstand extremely heavy loads Fig. 2 is a plan view taken from above of the blank after the same has been severed from the stock sheet,
Fig. 3 is a side elevation of the blank shown in Fig. 2,
Fig. 4 is a rear elevation of the blank after the second forming step,
Fig. 5 is a side elevation of the blank shown in Fig. 4,
imposed upon the supported gutter, Fig. 6 is a rear elevation similar to Fig. 4
It is a particular object of the invention to but after the next forming operation, provide an extremely strong gutter circle which F 7 is a e e tion of the blank shown in is made with a minimum waste of material, the only material being wasted being that Wasted Fig. 8 is a partial side elevation similar to Fig. by trimming relatively small areas in order to '7 but te the final fo mi g step, improve the appearance of the finished circle.

The base 3 of roof gutters frequently are subjected to overthe channel shaped section merges into the cenloading by ice and also by workmen such as tral portion 16a which lies between the attachpainters or the like, standing in the gutter or ing ears 4 and 5 and the p on iia continues placing ladders therein. The channel shape of upw rd y and is bent into the form of a retaining the major portion of the gutter circle and the l p I! which engages the uppe i n e f e corrugation of the attaching portion are specifigutter. cally designed to resist such overloading. The blank A shown in Figs. 2 and 3 is cut from a To the accomplishment of the foregoing and sheet of metal (not shown), the sheet being aprelated ends, said invention, then, consists of the p e y as Wide as the length of e a means hereinafter fully described and particu- Durin t e initial forming p Which y be larly pointed out in the claims. cutting, sawing, stamping or otherwise, the lip The annexed drawing and the following deii is bent slightly out of the plane of the blank scription set forth in detail one method and one A and the blank is trimmed to provide the curved product exemplifying my invention, such disend portion ill, the corresponding edges 6 and I,
closed procedure and product constituting, however, but one of various applications of the principle of my invention.
In said annexed drawing:
Fig. 1 is a perspective view of the completed gutter circle,
as well as the slots 8 and 9, and the curved end portion adjacent the lip II. All of this is done in one operation, thus saving time and labor and providing blank formed with a minimum amount of waste. It may be stated that the edges 6 and 1 at the right hand end of the blank A,
i) a as seen in Fig. 2, are results of the trimming operation, this trimming being done solely to enhance the appearance of the gutter circle in its final condition.
After the blank A has been formed by severing from a sheet of stock, it is then converted into a channel shaped member as shown in Figs. 4 and 5. Here it will be noted that the flanges I and 2 are co-extensive and parallel and eX- tend throughout the length of the circle to form the intermediate product orblank B. (See Figs. 4 and 5.)
The blank B is then subjected to a turther forming operation in which the attaching D01- tion is formed, this portion comprising spaced ears d and separated. by the central area. It. It is also to be noted that in this step, the area 16a lies in a plane slightly out of the plane of the ears 4 and 5, this resulting in what may be termed a corrugation which in turn lends considerable strength to the attaching portion and P vents the same from bending. This is a very important feature of my invention.
The clip 13 is next inserted in slots 8 and 9, after which the outer portions Iii-4'5 of the circle are bent toward flanges I and 2 respectively so that the slots decrease in width, thus retaining the clip in place. This bending may be performed by exerting force against the outer base portion 3 in the direction of the arrow Fig. 8', so that the small triangular portions l6 and H are bent about the clip 13 as shown in Fig. 8.
Referring nowto the clip, it will be noticed that this comprises. a wire-like member having a longitudinal portion it which is considerably longer than the distancebetween the flanges i and 2., This relatively longitudinal portion i3 is provided at its ends with hook members M and I15. The length of the clip, or stated in other words, the distance between the hooks l4 and [.5 is quite important since this permits the use of a single size of gutter circle with several different sizes of gutter. This last result is due to the fact that this clip is of resilient material and also because of the spacing of the hooks so that the hook- Hi, for example, may be slipped over thebead of a gutter, after which the hook l5 can he slipped over the side according to the dimensions of the gutter circle.
Referring now to Fig. 9, it will be seen that the parallel flanges lat-2a are bent along a line 2i; and forced toward each other so as to abut in the region between the line as and the lower outer edge of the circle. It is not deemed necessary to show a complete circle since the end portion only is modified, and the portion of the circle not shown in Fig. 9 corresponds exactly with the circle shown in Fig. l. The bending of the flanges and forcing the same together imparts strength to the outermost portion of the gutter circle, which is the point of greatest stress. This modification is provided with a slot 2! adapted to receive a clip as shown in Fig. 1.
Referring now to the modification in Fig. 10, this view is similar to Fig. 9 in that the remainder of the circle, which is not shown, corresponds to a like portion of the circle shown in Fig. 1. In this modification the blank need not be trimmed to provide the curved edges 6 and 1 as shownin Fig. 2 and consequently the blank will resemble a rectangle except for the curved portions adjacent the attaching apertures 12. Instead of trimming, the outermost portions 22 and 23 of flanges 2b and lb respectively are overlapped to form a closed clip receiving pocket.
d The clip 24 is easily inserted in the pocket formed by the overlapping portions 22 and 23 and after insertion, the ends 25 and 26 contact the exterior portions of flanges lb and 2b. The opposite end of the clip 24, that is the rounded portion, obviously is adaptedto engage the head of a gutter. This modification differs from the others in that waste is reduced to a positive minimum, and the clip engages the flanges of the gutter circle rather than a slot in such flanges.
From the foregoing it will be seen that I have provided a gutter circle which can be made with an extremely small amount of waste and it will be further noted that I can form my gutter circle with a relatively few simple steps. In addition, it will. be. noted that I have provided a clip which is permanently secured to the circle and one whichcan be used with various sizes of gutters. In addition, the clip can be easily attached to a gutter circle bead, as. distinguished irornclips having hook portionsv relatively closely spaced, thus requiring a different size, of gutter with each size of gutter circle.
In conclusion, it will be seen that I have pro.- vided a strong gutter circle since the gutter supporting portion is of channel shape throughout its length and it merges into a reinforced at.- tach-ins portion, the parallelflangesl and; 2: of the channel shaped portionextendi-ng; at sharp right angles to the attaching portion.
Other forms may be employed embodying. the features of my invention instead of the one here explained, change being made,- in the form or construction, provided the elements stated by any of the following; claims, or the equivalent of such stated elements be employed, whether; produced by my preferred method or by others embodying steps equivalent to those stated in the following claims.
