t pe of elejctried wire me char ed at will To all whom t may concern:



Be it known that I, GLENN `R. Wnmsrsn, acitizen of the United States, residrn'gsat Hayden, 4in the countyof Gila and Stlte of Arizona, have invented certainnew and use-` ful Improvements -1n Electrified Wire-Mesh Screens, of which the following is a speciti` cation.

My invention relates to electrified wire..

mesh screens, and more particularly to a s screens for winows.

The object is to' provide a means whereb current' o f an 'deslred kind or strength wi l enter' the bo y of an insectcr animal attempting to pass through or come in contact with .the live wires forming the said mesh.

I A further object is to provide a `window screen to all ap eara'nces similar to an ordinary screen, but one capable of being with an electric current of anp esired stren h,'kind or source.

n the preferre Figure l 1s a view offthe inside of a window iitted with myltype of screen, wherein the current suppl ing means is 1dia' ammatically shown. i 2 is an enlarge view-of a screen fitted wit an operative form' of my' imparovement, and of i ,Reirring -to `the several parts by numerals, 1 isa wiremesh screen having uninsulatedl wire sets 2 and-3, fthe 'former wire being electrically connected at opposite .ends to 'a conducting means `'4., and an insulating means 5, the atter `mentioned wire bein sinularly connected to similar means 6 an 7. The' conducting means 4 and `6 are disposed on opposite si 'es of the screen as shown and msulated therefrom. Electrical contact shoes 8 and 9 'are provided for, su plying current `from numeral 11 representing; the battery' and 12 a cutout switch. The wires l13 or the ques dis `osed vertically inlthe drawingare insulat to` revent short circuit. The insulated andt egninsulated-wires are woven Specification of Letters Patent. Application led June-1, 1912. .A Serial No. 701,678.

body of form I have 'here shown,

Fig. 3 is a setionalrview the power line 10, It 'e' ,I Patented pr.; 15, 1913.

similarly to an ordina shown, the operation of t e device beng'to form an electrical short circuit through'the way throug vcontact ;w1th two live. wires of. opposite polarity.

It will be obvious that the shoes have slidable contact with the respective strips 4 and ito the `end that the screen may be raised and lowered withoutbreakiug the charging circuit.

,1. In a wire mesh screen, conductin strips s .extendingon both vertical sidesof t esald screen, a plurality of parallel uninsulated wires each having" one end connected to a l'conducting strip, alternate wires beingconncted to opposite strips, insulating material disposed beneath in strips the free ends of the said .wires being secured to the said insulating material, a posed at right angles to the uninsulated wires and interwoven therewith, and contact shoes having electrical supply wires of opposite polarity connected thereto, the. said positive and negative conducting strips. l y

2.I n a device of the class described, a movable screen; conducting strips thereon; wires having one end only connected to one of these strips, alternate wires being `connected to opposite strips, shoes bearing slidably `uponthe strips, to permit a movement of the screen; an electrical circuit for which the shoes constitute terminals; and a source of current'supply interposed in the circuit.

In testimony wherof I aflix my signatur in presence of two witnesses.


R. I. Ezam' C. A. Huns'r;

plurality of insulated wires dis` the said "shoes being in slidable electrical contact with wire screen as y anything :attempting to force its hthe mesh or thatmaycom'e 1n the said conducir ,l
