This invention relates to circle suspending means adapted to facilitate thefastening of;

circle-type gutter hangers to existing buildings.

Suspension means for gutter hangers are quitev well known in the art and variousconstructions of attaching means. have been developed, which were more or less unsatisfactory. Most'of these devices are composed of -a"relatively frail-plate mounting and a shank member attached to the former by a single rivet, from which shank the.

so-called circle gutter hanger is suspended. The plate mounting is adapted to be permanently attached to the eave of a building. 1 These devices, a used heretofore, depend entirely upon the shear and stress resistance of such an attaching rivet to support the often very vrnuch overloaded gutthereby increasing the security of the device,-

" especially when subjected to unusual loads, such as heavy rains, snow and ice, gathering'in the gutter.

e A further object of my invention is to provide a plate mounting; in which a single strip of ma'-' terial is so constructed that certain of its parts serve as .guiding,'attaching and supporting means for a shank, while other of its parts serve for strengthening the mounting construction and for keeping it permanently in a desired alignment.

Another object of my invention is to provide in connection with such mounting a shank member equipped with integral plate-engaging means, adapted to register and securely interlock with specially designed parts of the mounting.

The foregoing and still further objects of my invention will become more fully apparent from the accompanying drawing, forming part of my disclosure, in which Figures 1 and 2 illustrate perspective views of a partly finished plate mounting.

Figure 3 is a perspective view of a finished plate mounting.

Figure 4 is a cross-sectional view taken on lines 4+4 of Figure 3.

Figure 5 is a partial perspective detail view of my shank end.

Figure 6 is a cross-sectionalview through a plate mounting equipped with an attached shank.

Figure 7 is a side elevation of my mounting r provided with a shank, and

:Figure 8 is a perspective view of a modified form of my plate mounting, adapted to be secured to the caves of a roof.

Referring .now specifically to the figures, nu-

meral 10 denotes the left-hand attaching portion of my plate mounting, whereas numeral 11 designates the right-hand portion thereof, both of which are provided with a plurality of apertures 12 for receiving screws, nails or other means, whereby the plate is secured to the suspension surface of a building. The material between the attaching portions is bentupon itself, so asro form a rib of a double thickness, of which'one portion, indicated at 13, remains solid, except for an aperture 14, while the other rib-portion 15 4s recessed, as shown at 16. The material removed from portion 15 to form recess 16 is indicated at 1'7, which latter constitutes an extension of attaching portion 10. This extension is adapted, when the article'is finished, to project beneath attaching portion 11, in which isprovided astepped-up reinforcing recess 18 intended to register with, and contain extension 17. The ex tension material is forcibly pressed into recess 18' and forms with the latter a firm connection between attaching portions 10 and 11 and preventsa displacement of the two portions in both lateral and longitudinal directions against one another. It will be. also observed from thefigures, that the finished. plate mounting is provided with a 5 stepped-up reinforcement 19, provided in attach ing portion 10, whichreinforcement corresponds to the stepped-up metal (forming recess 18) the latter, forms a reinforcement for attaching por- I tion 11. Reinforcement 19 also serves as seat for the channel-shaped shank flange 20, clearly seen in Figures 5 and 6.

In the web 21 of the shank, and near its upper end, there are pressed out from the web material upper and lower projections 22 and 23. Their engaging faces 24 and 25 are adapted to register with the upper and lower edges of recess 16, provided in one of the rib portions. An aperture 26, disposed between projections 22 and 23, is adapted V to register with opening 14, provided in the solid portion 13 of the-rib. Both openings serve for receiving a rivet, bolt or other fastening means, indicated at 27 in Figure 7, by means of which web 21 of the shank and portion 13 of the rib are drawn forcibly together, whereby projections 22 and 23 are caused to forcibly engage the upper and lower edges of recess 16.

Through this construction the shank is not only connected by means of rivet or bolt 27 with the plate mounting, but its projections 22 and 23 t 1 tion, a. platemounting consisting of a metal strip augment the attaching and supporting strength of the structure, whereby a greater security of the device is achieved. In addition to the above advantages, the shank and plate members are so connected with one another, that their joint prevents any movement between the two parts, thereby eliminating the possibility of the two members becoming loose relative to one another, even though they may be subjected to excessive abuse. 7

The interconnection between extension 17 and attaching portion 11 so reinforces the back of both attaching portions and the structure of the rib of the device, that a movement between these portions or a shift or distortion of the rib ismade absolutely impossible. a

In Figure 8 there is illustrated a modified form of my plate mounting, the entire upper structure tion, it is quite evident that improvements and changes may be incorporated therein, and I therefore reserve for myself the right to make such improvements within the scope of my idea,

without departing from its spirit and intent, as set forth in the claims annexed. I

I claim: 1. A circle suspension, comprising in combinahaving two sidewisely-extending attachingportions and a rib, made from the strip material, a recess provided in said rib, the portion ofthe rib material removed to form the recess .ex-

tending from one attaching portion beneath the other, and a shank secured to the recessed face of said rib and provided with recess engaging, integral projections. v

2. Ina circle suspension, the combination with a plate mounting, of a. shank permanently attached thereto, said plate mounting consisting ofa metal strip having two sidewisely disposed attaching portions, and a rib made from the folded-up strip material, a recess providedlin said rib, the material portion removed from the with and engage the recess of said rib for augmenting the suspending strength of the connection between the plate mounting and the shank.

3. In a circle suspension, a plate mounting designed for strengthening and increasing the suspension and fastening provisions of a shank, comprising a metal strip having two sidewisely extending attaching portions and a rib formed from thefolded-up strip material, said attaching portions having stepped-up reinforcements adjacent to said rib, a recess formed at one face of the rib, the material removed from the rib to form the recess extending from one attaching portion beneath and registering with the stepped-up reinforcement of the other attaching portion, thereby strengthening and forming a joint between the two portions, adapted to prevent them from moving laterally relative to one another.

4. In a circle suspension, a shank adapted to engage and to be fastened to a plate mounting, comprising a substantially channel-shaped member having a plurality of perforations for receiving fastening means of a circle, a pair of projections with oppositely disposed engaging faces provided at its attaching end, and a fastening means receiving aperture disposed between said projections.

5. In a circle suspension, the combination with a plate mounting provided with a double-Walled rib, one of the walls of the rib having. a recess; of a shank member provided with integral projections in engagement with said recess, and shank attaching means disposed between said projections and inengagement with the other wall of said rib.

6. In a circle suspension, the combination with 'a plate mountingprovided with a double-walled
