4 Claims. 1 j

The present invention relates to certain' new and useful improvements in Ways and means for effectively and satisfactorily sealing lapped ends of gutter sections used in constructing asemicircular eaves trough and has more particular reference to a simple and practical attachment f a ready-made and ready-to-use type.

It is customary practice to bond the overlapping ends of the stated gutter sections Aby way of solder or an equivalent sealing compound. Making a satisfactory solder joint is, however, a painstaking and time consuming task. Some roofers and guttermen do not do the job well and the ybond breaks and the trough or gutter soon leaks. rI'he object of the instant invention is, therefore, to pave the way for a superior bonded seam or joint. In carrying out the principles of the invention, it has been found both desirable and practicable to ll the joints with a mastic metal seal and to apply the latter by squeezing it between the lapped ends of the gutter section through the medium of a simple, readily applicable metal or equivalent joint bridging ban-d.

-An equally important object of the invention is to structurally, functionally and in other ways improve upon similarly made prior art constructions and, in doing so, to thus provide a feasible and economical attachment in which manufacturers, roofers and others will find their essential requirements and needs fully met and effectually contained.

With a view toward achieving these end results, a semi-circular saddle-like band is employed and is exteriorly applied and clamped in place, said band having its marginal edges formed with flanges to, in this manner, provi-de a shallow pan.

The pan is charged with a layer of felt or equivalent material which holds in place the aforementioned sealant, a satisfactory mastic metal seal, which is protectively covered and, when the cover has been removed, is squeezed by the clamping action of the band into the joint to effect the desired water-proof seal. l

Briefly summarized, a preferred embodiment of the invention has to do with the stated sha1- low plan having an attaching hook `at one end, having lug means at the opposite end and a readily attachable clip which is connectible with the lug means. The layer of felt and the sealing compound is in the pan and the compound is covered with a protective covering of a type which can be readily peeled off when it is desired to use the device.

Other objects and advantages will become more readily apparent from the following description and the accompanying sheet of drawings.

In the drawings:

Figure 1 is a perspective view of the improved gutter joint sealing means which, as before stated,- is in the form of a readily applicable ready-tQ-serve attachment.

Figure 2 is an enlarged -central cross-section taken on the line 2-,-2 of Figure 1, looking in the direction of the arrows;

Figure 3 is a fragmentary view showing the attachment applied to lapped gutter sections;

lFigure 4 is a fragmentary sectional view taken on the line 4 4 of Fig-ure 5, looking in the direction of the arrows; and

Figure 5 is a section on the line 5-5 of Figure 3, looking in the direction of the arrows.

Referring now to the drawings by way of ref.- erence numerals and accompanying lead lines, reference is made rst to Figure 3 wherein one gutter section is denoted by the numeral 6 and the complemental section by the numeral 1. These are conventional gutter sections and are 'of the semi-circular or half-round type. The outer wall portions of the gutter sections are provided wth customary rolled beads 8 and 9. In practice the ends are lapped as shown best in Figure 4 and one end is denoted at l0 and the other one at Il. This is the customary way of forming a scalable joint. The improved saddlelike attachment is characterized by a semi-circular shallow pan Idenoted by the numeral I2. This comprises a fiat strip of metal or equivalent material I4. The longitudinal edges are dared or bent laterally, as at I6 and I8, to form retaining flanges and to transform the band into the stated shallow pan. A strip of felt paper or an equivalent composition is fitted into the bottom of the pan and this is denoted at 20. This strip is covered with the semi-plastic sealant compound 22 which is a known mastic metal seal and which, when sufficiently exposed to air, hardens and provides the desired leak-proof seam. There is suflicient of the compound in the pan to -be squeezed and properly spread into the joint. The central portion yof the compound is cambered or formed with a slight crown 24 (see Figure 2) which aids in spreading the compound when the pan is tightly clamped on the gutter section in a manner to bridge the joint. The remaining layer of material is a protective covering 26 which may be fabric or any suitable gummed material which when ripped off eX- poses the available sealant compoun-d 24. This covering may be said te be peelable and one end of the same is shown partly peeled olf, as denoted at 28 lin Figure 1. Incidentally, this type of covering is used on innertube patches. One

end of the pan or strip is provided with a return bend 30 providing a hook and this hook is engaged over the lapped inner `edges of the sections '6 and 1 as shown best in Figure 5. The other end portion is provided with a rigid lub 32 having a keeper notch or hook 34 to accommodate the resilient clip 36. This clip is U-shaped and the bight portion 38 has a slight bend 40 which engages 'in' the keeper, The lateral arms 42-42 terminate -in hooks 44 which engage over the beads 8 and 9 in the manner shown in Figures 4 and 5.

It will be obvious that when the specially made pan or band is applied and clampedl in'place, the cover means 26 having been removed, the compound or sealant 24 will be squeezed and spread into the joint, as denoted at 46 in Figure 4. In due season it will set and harden. and the desired seam or seal will be completed.

By having these attachments ready-made, they can be lcarried on the jobqand readily applied and allowed, of course, to stay permanently in place. These attachments, too, are practicall devices for repairing gutters which vhave already been installed and where the' seam or joint has broken loose.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a vclear understanding of the invention after considering the description in yconnection with the drawingsThereflore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and arrangement of details coming within the iield of invention claimed may be resorted toin actual practice, if desired.

Having described the invention, what is claimed as new* is: y y k 1. An attachment for an eaves trough lapijoint comprising an arcuate joint bridging band having laterally bent longitudinal edges form- 4 ing flanges and transforming the band into a shallow pan, mastic sealant compound in said pan, `and a readily removable protective covering for said compound` said pan being provided at opposite ends with means whereby the same may be removably clamped on coacting gutter sections.

2. The structure specified in claim 1, wherein said sealant compound has 1a central raised crown and said covering is peelable to render it readily removable to expose the lcompound for use.

3. An attachment for an eaves trough lapjoint comprising a semi-circular shallow pan having means at opposite ends for attaching and clamping the pan in position on the trough section, a layer of felt inserted in said pan and forming a foundation, a layer of sealant compound spread on the top surface of said felt foundation, and readily removable covering means for said sealant compound.

4. An atta-chment for the lapped ends of semicircular gutter sections comprisingasemi-circular metal band having lateral marginal flanges forming a shallow pan, an insert of felt material fitted into said pan, a layer of mastic metal sealant material spread on and covering said felt material, said pan being provided at one end with an at taohing hook, being provided at the opposite end with a lug, and a hook-equipped clip detachably connectable with said lug.
