Abstract
A grass-clearing device for lawn sprinkler heads, wherein the grass and sod surrounding the in-line, sprinkler head is to be trimmed therefrom, to provide an unobstructed flow of water from the sprinkler head. The device comprises a pair of adjustable, cutting blades slidably secured to a support body, the blades being provided with a centering mechanism whereby the blades can be adjusted for proper cutting relative to the size of the sprinkler head. A telescoping, handle shaft is secured to the support body, the upper end of the handle including a foldable, hand grip connected thereto.
Claims2
A grass-clearing device for sprinkler heads related to underground water systems, wherein the device comprises:
- a main-support body having holes disposed adjacent the free ends thereof;
- a pair of cutting blades slidably attached to each of said free ends of said main-support body, wherein said cutting blade comprises:
- a horizontal arm member having an elongated slot disposed therein and a free end, said elongated slot being arranged to be aligned with respective holes of said main-support body;
- a depending, cutting, leg member formed as an integral part of said horizontal arm member, and bent inwardly thereof, having dual-cutting edges formed thereon, said leg member terminating with a free end;
- wherein said cutting, leg member includes a lateral, cutting edge disposed at the free end of said cutting leg member, and wherein a semi-circular notch is formed therein;
- a pair of tabs integrally formed as part of each said horizontal arm member said tabs being inwardly bent to slidably receive said main-support body therethrough, thereby preventing lateral movement of said cutting blades:
- a pair of V-shaped, jaw members, each being secured adjacent said free end of each said horizontal arm member, wherein the jaw members are positioned opposite to each other, to receive one of said sprinkler heads therebetween;
- means for adjusting said cutting blades to the proper distance apart with respect to the size of said sprinkler head, said means for adjusting said cutting blades being received in said elongated slots of said horizontal arm members and said holes disposed in said main-support body;
- a handle shaft having a first tubular shaft, one end of which is affixed to said main body, and a second shaft adapted to be received in said first tubular shaft, said first and second shafts having matching cross-sectional configurations, whereby said second shaft is prevented from rotation therein;
- a handle grip moveably attached to one end of said second shaft thereof, whereby said handle grip can be folded for storage;
- and
- locking means mounted to said telescoping, handle shaft, whereby said handle shaft can be positioned at a pre-determined length.
