US3716975A — Safety shield for powered lawn equipment

Claim 1

Independent Claim 249 words

In combination with a power lawn edger having a wheeled frame carrying a blade that is rotatable in a generally vertical, front-to-rear plane, and including a handle that is inclined upwardly and rearwardly from said wheeled frame to be gripped by an operator in a predetermined operating position to move the edger along a selected path, a safety shield for the protection of the operator from flying debris from said blades, comprising: an elongated shield extending along said handle and having an inclined lower portion extending downwardly to adjacent said wheeled frame and also extending upwardly across a first line from the lower portion of the body of the operator to the lower portion of the path of said blade, and having an upper portion positioned on the upper end of said lower portion and extending across a second line from the head of the operator in said predetermined position to the lower portion of the path of the blade; at least said upper portion being transparent to permit the operator to view said blade along said second line during movement of said edger along said path, and said shield being substantially imperforate between said lines; and means connected to said lower portion and mounting the shield on the handle of said edger for movement with the latter with said upper and lower portions positioned across said lines, thereby to protect the body and face of the operator from flying debris without interferring with normal operation of the edger.

Claim 2

Dependent Claim 249 words

In combination with a power lawn edger having a wheeled frame carrying a blade that is rotatable in a generally vertical, front-to-rear plane, and including a handle that is inclined upwardly and rearwardly from said wheeled frame to be gripped by an operator in a predetermined operating position to move the edger along a selected path, a safety shield for the protection of the operator from flying debris from said blades, comprising: an elongated shield extending along said handle and having an inclined lower portion extending downwardly to adjacent said wheeled frame and also extending upwardly across a first line from the lower portion of the body of the operator to the lower portion of the path of said blade, and having an upper portion positioned on the upper end of said lower portion and extending across a second line from the head of the operator in said predetermined position to the lower portion of the path of the blade; at least said upper portion being transparent to permit the operator to view said blade along said second line during movement of said edger along said path, and said shield being substantially imperforate between said lines; and means connected to said lower portion and mounting the shield on the handle of said edger for movement with the latter with said upper and lower portions positioned across said lines, thereby to protect the body and face of the operator from flying debris without interferring with normal operation of the edger.

Claim 3

Dependent Claim 249 words

In combination with a power lawn edger having a wheeled frame carrying a blade that is rotatable in a generally vertical, front-to-rear plane, and including a handle that is inclined upwardly and rearwardly from said wheeled frame to be gripped by an operator in a predetermined operating position to move the edger along a selected path, a safety shield for the protection of the operator from flying debris from said blades, comprising: an elongated shield extending along said handle and having an inclined lower portion extending downwardly to adjacent said wheeled frame and also extending upwardly across a first line from the lower portion of the body of the operator to the lower portion of the path of said blade, and having an upper portion positioned on the upper end of said lower portion and extending across a second line from the head of the operator in said predetermined position to the lower portion of the path of the blade; at least said upper portion being transparent to permit the operator to view said blade along said second line during movement of said edger along said path, and said shield being substantially imperforate between said lines; and means connected to said lower portion and mounting the shield on the handle of said edger for movement with the latter with said upper and lower portions positioned across said lines, thereby to protect the body and face of the operator from flying debris without interferring with normal operation of the edger.

Claim 4

Dependent Claim 249 words

In combination with a power lawn edger having a wheeled frame carrying a blade that is rotatable in a generally vertical, front-to-rear plane, and including a handle that is inclined upwardly and rearwardly from said wheeled frame to be gripped by an operator in a predetermined operating position to move the edger along a selected path, a safety shield for the protection of the operator from flying debris from said blades, comprising: an elongated shield extending along said handle and having an inclined lower portion extending downwardly to adjacent said wheeled frame and also extending upwardly across a first line from the lower portion of the body of the operator to the lower portion of the path of said blade, and having an upper portion positioned on the upper end of said lower portion and extending across a second line from the head of the operator in said predetermined position to the lower portion of the path of the blade; at least said upper portion being transparent to permit the operator to view said blade along said second line during movement of said edger along said path, and said shield being substantially imperforate between said lines; and means connected to said lower portion and mounting the shield on the handle of said edger for movement with the latter with said upper and lower portions positioned across said lines, thereby to protect the body and face of the operator from flying debris without interferring with normal operation of the edger.

Claim 5

Dependent Claim 59 words

The combination as defined in claim 1 in which said handle comprises at least one upwardly and rearwardly inclined arm, and said means connected to said shield and mounting the latter on said handle include a tubular frame member extending along and connected to one side of said shield, and a clamp connecting said frame member to said arm.

Claim 6

Dependent Claim 66 words

The combination as defined in claim 2 in which said handle has a lower end portion comprising two laterally spaced bars connected to said wheeled frame, and said shield has two tubular frame members extending along and connected to opposite sides of the shield, each of said tubular frame members being connected to one of said bars by one of said clamps, adjacent said wheeled frame.

Claim 7

Dependent Claim 22 words

The combination as defined in claim 3 in which said clamps are slidable longitudinally of said handle into different selected positions thereon.
