Abstract
A manually operable lawn-edge trimming implement consists of a blade-carrier, a knifing blade and a broom-stick handle by which the implement may be presented to the lawn edge and traversed therealong with the blade obliquely penetrated into the earth along the line of edge trimming. The blade-carrier acts as a clamp for removably holding the replaceable knifing blade, and the blade-carrier is supported by an axle on two wheels which are well spaced apart so as to prevent grass crushing in the lawn-edge vicinity.
Claims11
A blade-carrier for a lawn edge trimming implement including a handle which enables the implement to be manually traversed along a lawn edge with a blade in knifing relationship to said lawn edge, said blade-carrier comprising:
- a. a blade holder consisting of a pair of spaced generally parallel cheek-plates joined together by a handle-receiving socket sleeve extending therebetween, said sleeve being provided with a shape having a given diameter, said sleeve, in joining said check-plates together, being joined to each of said check plates in such a manner that as said check-plates are drawn closer together, the diameter of said sleeve is diminished.
- b. releasable clamping means to clamp said cheek-plates together and thereby to hold a removable knifing blade when positioned between said cheek-plates and to diminish the diameter of said socket sleeve,
- c. blade retention means to hold said knifing blade between said cheek-plates when said knife blade is positioned therebetween upon tightening of said clamping means,
- d. an axle upon which said blade holder is mounted, and
- e. two freely rotatable wheels on said axle, both being spaced from said blade holder and respectively located on either side thereof.

- b. releasable clamping means to clamp said cheek-plates together and thereby to hold a removable knifing blade positioned between said cheek-plates and to diminish the diameter of said socket sleeve,
- c. blade retention means on said cheek-plates,
- d. an axle upon which said blade holder is mounted,
- e. two freely rotatable wheels on said axle, both being spaced from said blade holder and respectively located on either side thereof,
- f. a handle having one end entered within said socket sleeve, and
- g. a knifing blade detachably clamped between said cheek-plates and so arranged that when said handle is grasped by a user so to project forwardly and downwardly from the user towards a lawn edge, said wheels straddle said lawn edge when said blade is disposed in knifing relationship with said lawn edge.
