The present invention relates to guards for roofing gutters and particularly to such removable guards cut in suitable lengths in the form of a screen either of perforated metal or wirecloth and designedto prevent the entry of'foreign matter whichhas-a tendency to clog the gutter.

- Itis an object of the invention tQi provide such a gutter'guardor screen which maybe readily'installed and easily removed by the householder without the assistance of skilled help.

It is another object ofthe' invention to provide such a; guardor screen in a partlyfabricate'd' form which is readily cut and formed into its final'form' by the householder and may, therefore, be lower in its sale price.

Other objects and features of' the invention will appear when the following description is considered in connection; with the annexed drawings Figure" 1' is a broken plan view of a section of gutter guard or screen in accordance with the preferred form of my invention;

Figure 2 is a cross-sectional'view of the screen of Figure 1;

Figure 3- is a detailed view showing the alteration ofthe cross-section of the screen wire in order to make it readily bendable at selected points;

Figure 4- shows a cross-section of one. form of roofinggutter and the adjacent building wall together with a guard'in accordance with Figures 1 and 2 in placeto preventthe entering or foreign matter intothe gutter;

Figure 5 is a view similar to Figure 4' but showing a second form of my invention in cross sec tion and in position on theroofi'ng gutter;

Figure 6 is a plan view of the form; of screen shown in section in Figure 5;

Figure 7 is a sectional view showing the screen of Figure 6;

Figure 8 is a view similar to Figure 4 showing a third form of the screen of my invention in place on a roofing gutter;

Figure 9 is a plan view of the screen of Figure 8; and

Figure 10 is a cross-sectional view of the screen of Figure 9.

Referring now to the drawings and particularly to Figures 1' and 2 thereof, the screen of this form of my" invention comprises the screen proper I o which is provided with the selvage edge it. This screen is, in its preferred form, made incontinuous lengths andmay be composed, for example, of wirecloth of three mesh to the inch and approximately eight inches wide. The wire 3 Claims; (01. 108-40) diameter used may be that commonly used co1 nmerciall-y and; known as hardware galvanized wirecloth.

Approximately one inch from one edge of the wire In the strands running in the direction per-' pendicular tothe edge are scored or weakened so'that the screen may be readily bent along this line. This scoring or weakening is indicated at; l2 in Figure 1 Likewiseat approximately two inches from the edge and parallel to the edge the strands are weakened by similar score lines l3. These points of weakening or scoring may be procured in any one of a number of manners. Thus the wiremay be mechanicallyflattened' at points such as I 2 and I3 to provide the lineof bending and the flattening may be in either of the forms shown in Figure 3, that is, maybe either rectangular in section as indicated at W in Figure 3, or a relatively round oval as indi cated at l5 in Figure 3 or may bea relatively flat oval as indicated at It in Figure 3. Ii. desirable, the lines of bending may be improved by omitting a strand of wire parallel to the edge at" the sectionwhere the bending is to takeplace or instead of 'scoring'the wires asshown in Figure 1 a comparable result may be obtained by locally heating the transverse wires in the areas such as l2 and I3 by means of high frequency currents to-the' annealing point of the cold" worked steel (IOOO F. to 1-100 F2) and allowing the product to:cool in airthussoftening'the steel wires on the bending: lines;

Due tothe' construction above described} the gutter guard or screen of my invention maybe shipped Itothe user in a roll, for example, of the conventional type of I00 feet in length and may then. be cut-in shorter lengths and'bent' to the form: shown in- Figure 2; that is; may be bent through-130 alongthe line formed by the weak'-- ened areas I 3 andthen bent'in-the opposite direc-- tion along the line; indicated' by'the weakened area I2: As a result the screen is provided with the=two bends designated n and ['8 inandl l and; as-so bent isin condition to be applied tothe roofing gutter in convenient sections."

The application to the gutter is extremely simple; as is indicated in Figure 4; in which the unbent selvage edge rest's; on the roof' 20} and the portion- [9 extending downwardly from the bend I 8 bearsagai'ns't the gutter edge 2+ and holds the screen or guard in its proper position by its own weight. It will; of course,-. be'undeifstood that the formof gutter shown in Figure 4' is merely illustrative and that the gutter guard of my invention is equally applicable to the many 3 other forms of roofing gutters which are in common use and particularly togutters made of wood.

In place thereof the wirecloth is berivasindi cated at 22 and a piece of metal as, forlxamples zinc is included within the bend. The zinc. is. be given a 180 bend along said second line after formed with a small bend on .the end thereof,"as

shown in Figure 'I at 23, and the wirecloth 1 011s bent and pressed together as indicated at 22 through 180- and includes the bend 2 3 o f the:

In the third f orm oi my invention shown; in --I?-figures 8;-9 and 10, each edge of the screen sectio-n'is enclosed a metal member, the

which is metal; member; on the "edge' ll of the screen which is: torest on the roof being designated. 36 and the metal member on the opposite or gutter edge being designated 30. The member 36. is. formed with a bend 31. therein which surrounds the'lefthand; edge thereby holding the member of the 801586-1110. If desirable the member 36 may be center punched as indica'tedat 38 to enhancethe-gripping action of the member upon the screen or the same effect may be obtained by stapling. In -a like manner a metal member 30 preferably of zinc is attached at'the other edge of the guard or screen section, this member 30 being formed similarly to the member 36 and being provided at the end of its lower extension with abend 33 which servesto stiffen the edge. Further, a' bend 3l-in members 30 and 36 serves to improve the contact of the wirecloth with the zinc strip and in the case of member 35, member 3l also provides suificient overhang to prevent mentioned above-in connection with the form of .11 extending along said wirecloth parallel to the -other edge and spaced therefrom, and a second line "oFWeaKned areas in the transverse wire,
