Patent CA-2098621-A1 (CA)
Title: Animal feeder
Inventor: RAHM MAURICE
IPC: A01K5/02
Filed: 1993-05-28
Abstract: ABSTRACT      This animal feeder is demand driven since only a feeding animal will cause feed to be dispensed.    An  elevated hopper containing granular feed has a pair of downward extensions which decrease in cross-section downward to an opening.   A pair of funnels are pivotally mounted immediately below these extensions and extend upward to bracket the extension.  The funnels are oriented vertically with the large end up unless the funnel is disturbed.  The small low ends of the funnels extend downward next to the feed trough bottom.   A feeding animal can move a low end to either side and incline the funnel from vertical.  A planar metering plate is centrally mounted within each funnel oriented such that it is horizontal when the funnel is vertical.  The metering plates are located immediately below each extension, are slightly larger than the openings, and do not extend completely across the funnel.  Feed from the hopper will build up on a horizontal plate surface rather than flow through the funnel.  When an animal displaces a funnel the plate is inclined off horizontal to permit feed to slide off the edge through the funnel into the trough.  This occurs only when an animal is feeding and displaces the funnel.

Title: Gardening tool for removing weeds
Inventor: TRAHAN ROGER
IPC: A01B1/16
Filed: 1993-09-08
Abstract: ABSTRACT           A tool  for  use  to  remove weeds,  especially dandelions,  which  comprises  an  open  rectangular  frame having an upper rod-like member defining a handle and a lower rod-like member of a length sufficient to receive the foot of an operator.   This open rectangular frame gives room not only to the foot of the operator, but also to his or her knee, thereby making the tool much easier to use. The  tool  also  comprises a  tapered  extraction  tube externally secured to a lower lateral side of the frame. This particular positioning of the extraction tube is of particular  importance,  since,  thanks  to  its  eccentric position, a rotational force may be applied to it by both the hand and foot of the operator which holds the frame, respectively.   Thanks to its  structure,  the taperated extraction  tube  is  also  self-cleaning,  as  it  empties automatically when another plug of soil or earth containing a weed to be extracted is inserted therein    The tool further comprises a basket for collecting the plugs of earth or soil extracted with the extraction tube from the lawn or turf.  This basket preferably has a flat bottom, an upstanding  peripheral  wall  and  a  width  substantially identical to the distance between the lateral members of the frame, thereby making snappable to the frame.  The tool may further comprise penetration depth adjustment blocks removably attachable to the lower, footstep-defining member of the frame to limit the depth of penetration of the extraction tube into the lawn or turf.
