Description
FRANK D. WARREN, OF COLORADO SPRINGS, COLORADO.
l ELECTRICAL FLY-KILLER.
Specification of Letters Patent,
Patented Apr. 8, 1913.
Application filed September 20, 1912. Serial No. 721,366.
To all whom, it 'may concern y Be it known that I, FRANK D. VARREN, a citizenl of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented certain new and useful Improvements in Elec.
trical Fly-Killers, of which t-he following is a full, clear, and exact description, ref- .erence being had to the accompanying drawmg.
Since it is the nature of flies to seek the *lightl and in so doing to swarm and* crawl upon the inner surface of the window glass, the' object of this inventionis tol provide a cheap, simple and effective device for eX- terminating the Hies as they crawl upon the window.
Other objects and advantages of the invention will be set forth in the ensuing description; y
- Referring to the drawing, Figure 1 shows a fragmental, elevation view of an ordinary window with the electricalv fly killer attached to the sash. Fig. 2 is an enlarged, perspective illustration of brackets F and K.
The electric' fly killer consists of two wires or bars, C and D respectively, charged with electricity of sufficient intensity to electrocute a fly; crawling across the said bars and thereby closing the circuit. Thebars C and D are strung across the inner surface of the window glass B in such a manner as to inberoept the passage of the flies, and close enough to the window glass to allow the flies to crawl over the said bars. The end E of bar D is secured to the bracket F by being laced through holes R and 'S.in said bracket and then clenched. The end Gr of bar C, being insulated, passes through a hole V in bracket F and is gripped by downwardly ext-ending flanges H integral with bracket F, said flanges being adapted to clamp the insulation of the said bar C by being bent over uponA it. Bracket F is placed in contact with the window glass B and secured to the window sash A by means of a. screwI, passing through the hole T in the base W o-f the said bracket VF. Bars C and D are secured at the opposite side of the window sash A by means of a bracket Ksimilar to bracket F. The free end M ,of bar D is to be connected to the Anegative pole, and the free end N of bar C to the positive pole of a battery or induction coil adapted to give a current of the required intensity.
The foregoing being a full, clear and exact description of the invention, what I claim and desire to secure by Letters Patent In combination with two or more parallel bars stretched across the surface of a window `pane and electrically energized and adapted to electrocute flies, said bars being supported by brackets adap'tedto hold them in position, an upper arm of said bracket adapted to alford gripping means for holding the'end of the upper bar, a plurality of holes in the said upper arm adapted to receive the end of the upper bar, the end of the upper bar adapted to be clenched, a lower arm of said bracket adapted to alford gripping means for holding the end of the lower bar, a hole .in the outer end of the said lower arm adapted to receive the ina hole in the said base adapted to receive a screw to secure the said bracket to the window sash.
Witness my hand this '17th day of `-Sept.,
. FRANK D. lVARR-EN. Witnesses JAMES H. BRUCE,
EMMA F. BANNoN.
