' '1 Claims. (01.156-14) This invention relates to' a means, for repairing wire screens, or for securing two wire screensto each other, or for securing. the edge of a sheet of wire screen to prevent fraying or opening of thescreen mesh at theends.

The object of this invention in its broadest aspect is to secure two pieces of screencloth to each other. i I

Another object of theinvetnion is to providea means of'securingthe ends of asheet of wire screen against fraying and consequent weakening. Y

Another object of the invention is to provide screen patches already treated with a securing 15 element in position around the rim of the patch to constitutea border by means of whichthe patch maybe readily attached and secured to a screen to cover a hole therein.

In order to secure one piece of screen-to an other piece of screen, or in order to'prevent the ends of the wire screen from fraying orsepa' rating, I Work or imbed the wire screen into a provided with a narrow border of soft pure lead,

wire which has been worked into the screen mesh so that it is securely interlocked therewith. The patch is then ready to be secured to another sheet of wire screen, for the purpose of covering a hole therein, for example, by tightly pressing or by lightly beating the lead border into the mesh of 40 the screen that is to be repaired.

The same principle of securing two pieces of sheet screen is applicable where it is desired merely to attach the end of one sheet of wire screen to another sheet of wire screen, as where one sheet may not be sufficient in length and it is necessary to secure another piece thereto, to render it suitable for the purpose for which the screen is to be used.

use of the soft lead wire as a means for securely anchoring the edge of a sheet of screen in the usual soft wooden frame with which the sheet of wire screen is to be assembled.

The various modifications referred to are Another aspect of the invention involves the illustrated and described drawing, in which 1 i c Figure .1 is a front elevational' view of ausual screen to which a patch has been applied in ac- I cordance with the principles of this invention; 0

Figure 2 is a front elevational view of a screen 1 patch in the form in which it is shown applied to" the screen in Figure -1; A I i w :Figure 3 is an edge view of the screen patch in the accompanying .ofFigure' 2 showing-the disposition ofastrip or 5 wire of soft pure lead when first placed against the'screen;v x

Figure l is a View of the screen in Figure '3 after the-wire'orstrip of softpure lead has been pressed into intimate with the screen;

Figure 5'is a similar View showing a magnified section inwhich the'wire or strip' of soft leadis used to secure two pieces of screen together; I

-JFigure 6"is'a front elevationalview showing-the manner in which two edges of screen'are secured together to provide a longer sheetof screen; --Fig'ure .7 isf"a front elevational view illustrating an arrangement whereby one edge of a sheet of' screenis anchored in a wooden frame, with which the sheet of screen is to be assembled as a window screen or as'a door screen; and

Figure 8 is a side sectional view of the assembly shown in Figure '7 illustrating the manner in which the softlead strip, which holds the ends of the screen Wires against fraying, serves also as an anchoring elementwhich is embedded in the wooden frame.

As is illustrated in Figure 1, a large screen 10,

having a hole 11 therein, is repaired by means of I screen, so that the lead border is substantially in- I tegral with the screen and closely adherent thereto. V

Because of the soft ductile character of pure lead it may be readily pressed or hammered into a sheet of wire screen in such manner as to form 1 small lugs 15 that enter into the spaces between the wires forming the wirescreen. When the screen is well supported on one side, while the lead wire or strip is pressed into, or hammered into,-the screen from the other side, the small lug X interlocking relationship l v 2 r portions 15 entering into the spaces between the wires of the screen will be caused toembrace those wires, thereby forming a closely and intimately interlocked bond between the lead strip 5 and the wire screen, so that the two become sub- 25.;Figure 6, to secure the edges of two sections of stantially integral and closely adherent, as illustrated in Figure 4.

When the screen patch 12 is to be attached to another sheet of screen, the patch 12 is applied to the screen so that the unworked portion of the border of lead strip 14 will engage the surface of the screen to which the patch is to be attached. When the lead border is hammered into position so that it will similarly engage and intimately interlock with the screen that is to be repaired, or to which the patch isto be attached, the lead strip will similarly engage that screen and form a tightly interlocked bond which functions substantially as a soft metal Weld between the two sheets of metal screen. A closely adherent and tightly secured bond is thus established between the two sheets of screen. f

This same method 'of'bonding two pieces of screen 16 and 17 may be employed, as illustrated in screen cloth together. I

.Such abond, as. illustrated in Figure 6, or in Figure 2 in connection with the patch, also serves to prevent fraying or dispersing of the. ends of the ;screen cloth, and thereby .strengthens the cloth since it'prevents the weakening at the edges with consequent stretching and ter of the screen. 5 I

In order to further utilize the lead wire bonding ';-medium as an anchoring element for the screen, 'the lead strip 14, after being bonded to the ends of a wirescreen cloth along its edge, may be hammered into, and imbedded in, the woodenframe 18 of a'window screen or door 19 with which-the 3 sheet ofxwire screen is'to be assembled, as illustrated in Figures 7 and 8.

My invention; is not limited to the particular application of the screen patches, illustrated and weakening in the cen-" described herein, nor to any particular bonding metal, but may be variously modified without de-- parting from the spirit and scope of the invention as set forth in the appended claims.

I claim as my invention:

1. An article of manufacture consisting of a strip of screen having a border of soft workable metal secured thereto.

"2-. ,An article of manufacture consisting of a strip of screen having a border of lead strip;

worked into intimate interlocking relationship ,with the screen.

an edge thereof, which material may be readily worked into intimate interlocking relationshipwith a similar strip of screento which thearticle isto be attached.

6. Anarticle of manufacture consisting of a strip of screen having a binding. element .atan' edge thereof, part of said element being securely worked into intimate interlocking relationship with ,thescreen, and part of the element being available to be worked into intimate interlocking.

relationship with a similar strip of screen to which the article is to be attached. l

7. An article of manufacture consisting of a screen patch having a bindermaterial secured at predetermined locationsalong onesurface of the patch whereby the patchmay be applied to cover 1 a hole in. another screen and secured in position to such other screen with the patch and the screen in" flat parallel plane relationship.
