This invention resides substantially in the combination, construction, arrangement, and relative location of parts, all in accordance with the disclosure herein.

Figure 7 is a section on the line 1-1 Figure 6.
The true nature and manner of use of a device in accordance with this invention will be best understood by a detailed description of the form thereof shown in the drawings in an illustrative sense.
A preferred form in accordance with this invention includes parallel main electrodes 2 and 3 longitudinally extended between opposite members 4 and 5; spaced by one or more spacing means comprising a wire member b one end of which is in fixed engagement with main electrode 2 the opposite end being wrapped around the outer periphery of the insulating member 0 thru which main electrode 3 passes; insulated therefrom by suitable insulating members 6 and being in contact with a source of electric current thru conductors l and 8 either directly or thru atransformer depending upon the desired voltage.
Suspended from said main longitudinal electrodes 2 and 3 are a series of vertical tap electrodes 9 and [0 which may be hooked to the invention to pro- 1 in close proiiiih'itytb' or contact with the elec allychalrged ele ems; b'y'iwhicl'i they are e1 un ut-ea, wur fall clear or the elements i s' and" notfclogor obstruct the'l pace" theelbtfdds anui possisiecaus ng of a' a clogging around the top rim of the insulator vention is to with; secured I means of solder, or in any other suitabllbr ventional-ma-nherj i i 0bservation-- of Figures 1 and 2 teachesthat roarsm nszed preue terminedispace as tocachother "by meane onw'ire said tap electrodes 9 and spacing; members Hf which is in: fixed engage ment with the electrode 9 in a manner such 'as above dCSGll'bEdrfOIrlihG" engagement: of thee tap electrodesw ith thermain electrodes the opposite end thereof circumscribings the outer. periphery t e l in m r h (W ich th electrodelllfpasses and wh e in the drawing only a single: spacing means is shown for each pair of electrodes, it is obvious of the tap electrodes should demand additional spacers same could be. supplied without impairing the spirit of the invention.
As herein pointed out an object of this inprovide a device of the character here described whereby the carcass of the insect will fall clear of the electrodes and especially is this true in the structure above described, wherein the path between any pair of electrodes is normally so close that the additional thickness of the insulator [2 would tend toward causing l2 thereby obstructing the path between the electrodes, and possible shorting of the circuit, therefore to overcome this possible condition the electrode 9 is indented at I4 from above thetop of said insulator l2 thus permitting any carcass to pass same and fallclear of the elements.
Now referring to Figures 3, 4, and 5, which illustrate a modified form of structure it will be observed that in the main the structure is composed of two gratings l5 and I6 which are embodied Within a frame [1, in insulated fixed engagement therewith at the four corners thereof thru insulating members l8. Each of these gratings comprise an assembly of grids in the form of parallel vertical electrodes I9 and 20 which may be termed main electrodes, and a series of parallel horizontal tap electrodes 2| and 22 which are respectively connected in unitary circuit assembly by solder connection, splicing, or other conventional connecting means, however, observation of Figure 4 will teach that if both vertical electrodes were run in contact with their respective horizontal electrodes in their normal plane, said vertical electrodes would be so close that the insect carcasses would readily clog and obstruct any passage therebetween, therefore to assure a clear passage the horizontal electrodes eietroues anupresseumr contactthere: therewith by end turns; joinedfby that, if the length 22 are indented at 24 and the vertical electrode 20 run within the space thus provided.
In this structure it is thought best to make contact with a source of electricity thru the vertical electrodes, and as indicated thru represented conductors 25 and 26.
Figures 6 and '7 illustrate a further modified form of structure wherein there is a double set of triangular gratings 30 and 3| in the form of vertical grids orelectrodes 32 and;33 in circuit contact withparallel horizontal electrodes 34 and 35 respectively.
Similar to other forms of structure herein described, it is necessary that the structure be so formed that the passage between opposite vertisire to be strictly limited by the disclosure but rather by the claims granted me.
What is claimed is: r
l. A device of the kind described, comprising a normally open electrical charging circuit, and including independent groups of fretwork-like contacts spaced from each other for clearances between such groups and the contacts thereof, closing of said circuit being efiected by engagement of aninsect withzcontacts of both groups thereof. T r
2. A device of the kind described, comprising i .a;normally open electrical charging circuit, in-
I eluding independent tacts spaced from each other for clearances becal electrodes be kept clear, to this endthe apex terminals of the grating 3| is receded in a manner as shown at 36 and thevertical electrode -33 run within the space thus provided.
As previously pointed out, it is desired, although not compulsory in anyfform of structure, that electrical contact shall 7 be) made vertical electrodes.
In thismodified structure there i s shownl an electric lighting means, however this is a well known means for attracting insects and no claim is made to this individual item, same being shown toillustrate, one manner of using this particular structure.
:fFrom the above description it willbe apparent to-those skilled in the art that the-details ofconstruction illustrated-herein may readily be varied without departure from thenovel subjectmatter herein disclosed. I donot therefore, de
groups of fretwork-like con-,
tweensuch groups and the contacts thereof, the
closing of said circuit being effected by engagemerit of an" insect with the contacts of both groupsthereof, and insulating means holding the gr ups of contacts in their spaced relation to each other/for minimizing insect clogging of the 3. A device of the kind described, comprising a normally open electrical charging circuit, fin-Q eluding independent groups of'bar-like contacts spaced from each other for clearances between such groups and the contacts thereof, the closing of said circuit being effected by engagement of an insect with the contacts of both groups thereof, insulating means holding the groups of contacts in their spaced relation to each other for minimizing insect clogging of the clearances, and means for supporting said groups'of "contacts and the insulating means assembled.
