{Be 1t known/that LJOHN L. D Av1'DsoN,. cit-'Titten4l of the UnitedStates, residing at Bai-net, inthe county of Caledonra and State of Yei jn1o11t',-l1ave invented certain new and:

- For a full understanding' of the invention, reference is to be had to the following de- Fi ure 1 is a front perspective view of' the y catcher showing the same supported When occasion. requires.' l

ons -that the removal ofv the sheet of paper '95 bythe block; Fig, 2 is rearperspveetire View g4 and Fig. 3 is a longitudinalsec'tion.' Corresponding andv like 'parts are referred, to in the following description and indicated I ,in all the views of the A' saniereferen'ce characters. I My improved iiy catcher consists,fessen. tially, of a tray that serves as a fly pape-r' holder. The tray has a bottom orhaseplatev l which is substantially flat, although .not 65 necessarily so, the bottom being oany suitable size or shape and being shown in the present instance as of'rectangular form. The bottom is provided a't allv of its edges with an upturned 4rini 2` The entire tray is 70 preferably formed `from a single .piece of suitable sheet metal, the edge :portions otV which are bent upwardly to form therini.- A sheet of sticky paper B'lits snugly with- Y in the rim and lies Hat' against the` bottom .1.7.5

with itsV adhesive side exposed. In order to maintain the paper in place, a plurality of lugs 4 project i are arranged in spaced engage over the edge portions4 of the sheet of paper, as shown. The sheet of paper extends across and 'closes a relatively large opening 5 that is formed in the bottom of the tray.- The purpose of this opening is to 35 `permit the finger to be inserted therethrough away from the to press the sheet of paper bottom 'l and out of engagement with the inwardlyprojecting lugs 4. A niaterial advantage 1s attained with this arrangement 99 inasmuch as the sheet of paper is rendered susceptible of beiiig expeditiously removed from the tray to be 4replaced by 'a new,sheet It 'i v il1., be .obvi

may be effected withoutthe finger of the operator coming into contact With the adhesive surface'.

The tray may be moved about by means ot a hantlle 6 which 'is preferably formed of a 10b single length of stout wire that is doubled 'upon itself at anintermediate point to form spring arms 7.' Thea-rms are crossed intermediate of theirends and have inwardly bent extremities 8- that are action of the arms, in A transversely spaced apertures 9 extending through the bottom Inasln'uch as --the arms are crossed, there is a tendenc for the engagement with free ends thereof to spring toget er, and 11 inwardly from the rim at suitable intervals and relation to the bottoni of the tray so as -to held by the spring this, of course, insures`the bent extremities- '9 being firmly' retained at all times in engageinentwith the a 'ertures, although admittil o f-the handle eing readily detached froml t e tray by merely pressing the arms apart. One of tV e spring arms is somewhat longer ythan the other and the apertures 9. are spaced eplart -in the direction 'of the length of the andle in order to compensate' for thisdift'er'ence in the length of the arms. By virture' of this construction, the handle is held against turning movement about the bent extremities -9 as pivots andl is maintained. rigidl in oblique relation to the plane of the ottoni of the tray, the handle,

projecting ,considerably beyond one end of `the tray so as to be conveniently grasped when using the device., A.

' In practice, `the catcher may be moved rapidly about to cause the flies vto'strike against and be retained by the adhesive'surface of; the sheet of paper 3. The tray may also be placed over a fly or flies which have `vlighted on a vvall'or like Hat object, the flies being caught vby the sticky 'paper as they at-v tempttoescape. -In this instance the upstanding rim 2 'prevents the adhesive sur- Y `faceof the'paper from coming into Contact with the wall.

v Attentionjis particularly directed. to the fact that the vlugs 4 are' struck from the metal forming the rim. Outlet openings 10 are thus provided in the rim` and permit the air to escape from the tray .as the device is moved about, so as'not'to hinder such move'- ment. l The free passage of air through the tray avoids the formation of an air cushion 'asaivould possiblypermit theinsects'- to escape. i From 'the foregoing'4 description 'in ccnl. nection Withthe' accompanying d'rawing, it

-.Will be ap arent that II' have-provided an' l improved '.f yucatch'er which' is quite efficient 'in operation,` which is not likely to' get out of: order, andwhicli possesses to marked degree the characteristics of simplicity, dus' rability and stren th., The (levi-ce consists of coin'paratively parts that are capable of: leing easily and cheaply manufactured so as to-perinit .the invention to be,placedcnv the-market at a price not toogreat to. 'pre "vent its general adoption.' I

.It is to be vui'iderst'oo'd,that the-'device ma made in 'various' 'sizes-'it bei-ng "tonteml.

lated to equip the larger sizes with long,

handles to permit their use in capturing iiies on the ceilin 'of rooms.

AWhere it is not desired to move the de- Y. j vlce about to catch theflies, the saine may be supported in a stationary position in any suitable manner, as by means of a block-11 that is adapted to rest upon atable or like support and is formed with a slot 12 -into which thereturnedend-'of the handle may be iitted frictionally, as illustrated in Fig. 1.

The handle may be disposed at a greater angle tothe tra than in Figsal and 2, as

for instance, asi lustrate'dV in Fig'. 3. 1 Having thus described :the invention, what is claimed as new is:

l'` A iy catcher including a plate, ai`inarginal rim outstanding fromone side ofthe plate, and a plurality of lugs projecting in#- Wardly. from the rim and arranged to en gage over a sheet of sticky paper to hold the same against the plate, the lugs being struck from the rim to provide air outlet openings therein for the purpose specified.

2. As a new article of manufacture, al'Hy catcher comprising a handle, and a tray se' cured to the handle and consisting of a bottoni, an upstanding rim, and a plurality'of "lugs projecting .inwardly from the rii'n and the other topi-event the handle from turn- -ing relative'to 'the tray.

v 4.. As a new article of manufacture, av fly catcher comprisinga tray -for holding a-.sheet oflsticlcy paper, and a handle :including a pair of spring arms connected' together at one eiid'and crossed intermediate of their ends, withv their free terminals engaged with the tray. A
