US Patent:

47385715, Apr 19, 1988

Filed:

Sep 29, 1982

Appl. No.:

6/426744

Inventors:

Eugene T. Olson - Anoka MN
Larry E. Olson - Blaine MN

International Classification:

B23C 120
B23B 4734

US Classification:

409137

Abstract:

In a preferred form, the dust extraction system is intended to be used in combination with a conventional router. The system includes a plate, one side of which confronts the router's ring base. The plate has a relatively small hole through which the cutter bit extends and an offset larger hole through which dust-laden air is withdrawn. A recessed sub base, preferably of plastic, confronts the other side of the plate, the sub base also having a relatively large hole through which the bit extends. Both the plate and the sub base conform in shape to each other, having portions extending laterally to one side of the router's base. The offset hole in the plate is formed in its laterally extending portion and the recess or cavity in the sub base, forming a passage with the overlying plate, extends to this hole. A sleeve surrounding the hole enables a source of subatmospheric pressure to be connected in order to extract the dust produced by the router's bit. Provision is made for mounting the router for reciprocal movement toward and away from a frame on which the work is placed.

Appl. No.:

6/065835

Inventors:

Larry E. Olson - Blaine MN

International Classification:

B27B 529

US Classification:

83100

Abstract:

A guard casing encloses a substantial portion of the blade of a circular power saw. A cylindrical tube is carried by the casing for connection to a source of vacuum, the cylindrical tube having a slot extending longitudinally from one end thereof for accommodating therein a peripheral segment of the saw blade so that the sawdust produced by the blade is more efficiently collected. The cylindrical tube is adjustably mounted so that its slot can be appropriately positioned relative to the saw blade.

Appl. No.:

17/683517

Inventors:

Larry Eugene Olson - Ham Lake MN, US

International Classification:

A47G 29/12

Abstract:

In a mailbox delivery alert system, a closure abutment secured to an outer end of an arm is pushed by pivoting a mailbox closure from a closed position to an open position, and the arm is moveably mounted relative to a flag intermediate its ends for movement parallel to and at non-parallel angles to the flag height. The moving arm pushes an arm abutment secured to an inner end of the arm against the flag intermediate its ends, with the arm abutment pivoting the flag from a home position to an alert position.
