Specification of Letters Patent.

Patented Apr. (it, 19115..

Application filed may 5, 1914. Serial no. scenes.

To all whom it may concern:

Be it knownthat I, EDWARD A. DEAnDorF, a citizen of the United States, residing at Davenport, in the county of Scott and State and use-' .cient in use, strong, and durable.

Other objects and advantages of this invention will be apparent during'the course of the following description.

In'the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of a trap embodying the invention, Fig. 2 is a transverse sectional view taken on line 2-42. of Fig. 1, Fig, 3 isa longitudinal sectional view taken on line 3-3 of Fig. 2 and Fig. 4 is a horizontal sectional view taken on line li-A of Fig. 2, parts being 'broken away for the sake of illustration.

In the drawings, wherein for the purpose of illustration are shown preferred embodi ments of the invention, attention being called to Figs. 1 to 4: inclusive, the numeral 5 designates a lower receiving shell or chamber, having its longitudinal sides provided with inlet openings 6, preferably .50 v 'tion of tl'US PIGCISQ arrangement is to prowhen the roach passes :the other inlet tube,

beveled and increasing in diameter outwardly. Arranged within these inlet openings 6' are inlet tubes 7 preferably conical and preferably formed of wire screen or fabric. Particular attention is called to the fact that there are two oppositely arranged sets of these inlet tubes, which form trans- Y verse pairs of the same. In each transverse pair,.the inncrend of one inlet tube is arranged contiguous with the inner end of such inner ends overlappingfor a suitable distance. The funcvide means whereby from the innerendof one tube he will be conducted directly upon the exterior surface of. the other inlet tube of the same screen.

pair for a purpose to be more fully explained. The

receiving shell or chamber 5 has its upper end closed by means of atop 8, provided with a centrally arranged opening 9; Se-

.cured within the opening 9, as more clearly shown in Fig. 3, ,is an upstanding outlet tube 10, preferably tapered, decreasing in diameter upwardly, and formed of 'W-l.ll

Arranged within the upper portion of the receiving shell or chamber his a pyramidal conducting or deflector chutell,

decreasing in width upwardly with its cons tracted' outlet end 12in registration with the opening 9. The lower large end of this conducting chute 11 terminates adjacent the outer large ends of the inlet tubes 7, whereby the roaches or other insects crawling exteriorly upon these inlet tubes will crawl upwardly along the inner wall of theoonducting chute 11, and through the upstanding outlet tube 10. Adapted to be removably mounted upon the top of the receiving;

shell or chamber 5 is an upper retaining end thereof, onto a conical check plate '16,

increasing in diameter downwardly and'secured upon the upper end of the tube '15, to surround the same. The upper surface of this check plate 16 .is preferably polished or shell or chamber 13, provided with a cen- 'trally arranged opening 14, having secured therein the lower end of an outer upstand- The outer outlet rendered smooth, whereby the roach when passing thereon will quickly slip ofi of the same into I v be positively prevented thereby from returning nto the tube'15 by crawling upwardly along the exterior thereof.

theretaining chamber 13 but will One end of the retaining casing or chainber 13' is preferably provided. with a vertically movable slide door 17, operating v withinguides18 or the like. This slide door may be'moved by a handle 19, secured to the upper end; thereof. The'top of the retaining casing or chamber 13 is preferably provided with a longitudinally extending sight opening 20, which may be spanned by a section of wire screen 21. This sight opening enables the operator to see the reaches 13, and also to pour-hot water orithe like into-the. chamber or shell to'kill them.

in operating the-trap, the bait is placed. within the retaining shell or. chamber-13.

This bait attracts the roaches onother in sects, which 'pass into certain-"of the inlet ing hot ,i'va

U on passing fromrthe outlet end, of the tu' "e lathe roaches slip upon the check plate 16 and fall'to the floor or bottom (it-the retaining shell or chamber i3, wherein they may be killed, as by Penn ter or thelike through the sight opening 20; It is particularly convenient to form-"theretaining chamber 13 separate or 'einovable' froinlthe receiving chamber '5, so that the-retaining'chamber may be separated from the re'cei-Vingbhamber and carried to' thefdesired place, for replenishingthejbait, or removing or" killing the roaches.

It is to'beju'nders'tcod that the form of my invention herewith shown and described is to be taken 'jas'a 'preferre'dexample of the saine, and that variouschange's in the shape,-

of parts may be. resorted to without departing from the spirit of the invention'or. thel scope' of the subjoined claims."
