ELECTRIC SUCTION INSECT-TRAP.

Specification of Letters Patent.

Patented June 18, 1912.

, Application filed July 1, 19 11. Seria1 No. 636,320.

To all whom it may concern Be it known that I, FRANCIS M. BRITTON, citizen of the United States of America, residing at Minot, in the county of lard and State of North Dakota, have invented certain new and useful Improvements in Electric Suction Insect-Traps, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to insect catching devices and the principal object of the same is to provide a housing having a fan positioned therein and having an inlet through which the insects are sucked into thehousing and outlets through which the insects are driven into a compartment wherein they are held until it is desired to remove them.

This invention is illustrated in the accompanying drawings wherein Figure 1 is a perspective view of the insect catching device in operation. Fig. 2 is an enlarged View in side elevation of the catching device. Fig. 8 is a view of the catching device with the housing and inlet shown in section. Fig. 4 is a vertical section taken through the housing at right angles with a section of Fig. 3 and looking toward the front wall of the housing. Fig. is a view similar to Fig. 1 looking toward the rear wall of the housing.

Referring to the accompanying drawings by numerals it will be seen that the invention comprises the support 1 which carries an electric motor 2 similar to those used in electric fans. It will, of course, be obvious that any other type of motor may be used. Arms 3 extend from the motor and their outer ends 4 pass through the slots 5 formed in the rear wall 6 of a housing. The rear wall 6 is provided with a flange 7 in which the side wall 8 of the housing fits. A frame 9 similar to the ordinary frame which surrounds a fan is mounted within the housing, and the ends 4 of the arms 3 are secured to the frame 9. The shaft of the motor extends through an opening 11 formed through the rear wall 6 into the housing and a hub 12 provided with arms 13 is secured to the inner end of the shaft by means of the set screw 14. Plates 15 having curved outer portions 16 are secured to the arms 13 so that when the shaft 10 is rotated the plates will revolve and cause an air suction through the housing. The front wall 17 having a flange 18 is placed upon the front of the wall 8 with the flange 18 inclosing the wall 8 and is held in place by any desired means. It will thus be seen that the wall 8 is par tlally inclosed by the flanges 7 and 18, thus entirely inclosing the frame 9 and plates 15. A sleeve 19 extending from the central portion of the front wall 17, and a funnel 20 is inserted in the sleeve 19 and serves as a guide for leading insects into the housing. Sleeves 21 and 22 extend from opposite sides of the wall 8 and a funnel 23 is mounted in the sleeve 21. It will, of course, be obvious that a funnel similar to 23 may be also mounted in the sleeve 22. Guide plates 2% are secured to the inner face of the wall 8 adjacent sleeves 21 and 22, and are positioned so that the draft caused by the fan will be directed through the sleeves and thus carry the insects out of the case into the funnels 23. A netting 25 is mounted in the outer end of each funnel 23 and is held in place by means of clips 26 which engage the outer edge of the funnel. It will thus be seen that the insects which are driven through the sleeves 21 and 22 will be held within the funnel 23 and will be prevented from escaping by the screens 25.

In using this device it is set in a place where insects are liable to gather such for instance as near the window of a room. When the motor is started this rotates the fan and causes the suction through the fun nel 20. The draft passes through the funnel 20 into the housing and then passes out through the sleeves 21 and 22. The insects will be sucked in through the funnel 20 and then driven out through the sleeves 21 and 22 into the funnel 23 where they will be held until they are removed. The guide plates 21 assist in directing the air and insects into the sleeves 21 and 22. If desired bait of any nature may be placed near the catching device so that the insects will be attracted to the device.

What I claim is 1. A trap comprising a motor, a fan mounted upon the shaft of said motor, a housing inclosing said fan, an inlet leading from said housing, a plurality of outlets leading from said housing, guiding plates ing air through said outlets, and receptacles 10 secured to the lnner face of the said housing connected with said outlets. and adjacent said outlets for directing air In testimony whereof I hereunto aflix my through said outlets and receptacles adapted signature in presence of two Witnesses.

to be connected with said outlets.

2. A trap comprising a housing provided FRANCIS BRITTON' with an inlet and with outlets, a fan in said Witnesses: houslng, and guidlng plates mounted upon FRANK CLEGG, said housing ad aCent said outlets for dlrect- GEO. BEEHR.
