LAWN EDGING TOOL Filed Oct. 8, 1930 Patented Sept. l l93i TENT OFFICE EDWARD J. GASSE, OF

nn'rnorr, MICHIGAN LAWN EDGING TOOL Application filed October 8, 1930. Serial No. 487,169.

This invention relates to lawn-edging tools, and particularly to tools for forming a small trench in a lawn, along a sidewalk or other structure.

' s An object of the invention is to adapt a lawn-edgingtoolto be moved either forward or back along a sidewalk edge and to cut, 1n either direction, a shallow trench neatly and accurately bordering the walk. I

Another object is to so form the cutting edges of a tool of the described character as to minimize the effort requisite to manipulate the tool and derive a maximum cutting efliciency from said edges.

These and various other objects the invention attains by the construction hereinafter described and illustratedin the accompanying drawings, wherein:

' Fig. l is a perspective view of the improved 20 tool in use. I

- Fig. 2 is a cross sectional view of the same.

Fig. 3 is a plan view of. the plate from which the cutting member of the tool is formed. v

In these views, the reference character 1 designates a sod cutter of an approximate J shape, formed from a single metallic plate, preferably steel, and comprising a horizontal cutting member 2, a vertical guide member 3 30 rising from a lateral margin of the member 2,

a horizontal guide member 4 integrally laterally projecting from the member 3, at the top thereof, and a vertical member 5 integrally risin from the other lateral margin of the p mem er 2, and considerably exceedin the member 3 in vertical extent. The mem ber 2 has reentrant cutting edges 6 at its front and back, and the vertical cutter 5 has reentrant cutting edges 7, 8 of approximate V-shape, the edges 8 being, however, inclined at a greater angle to the vertical in extending upwardly than the edges 7. The guide members 4 and 3 are engagable respectively with the top and lateral faces of a sidewalk 9 or other boundary member of a lawn, and the member 4 has its front and rear edges slightly upturned, as indicated at 10, to avoid interference with sliding actuation of the cutter by any slight unevenness in the engaged top face of the walk. Secured to said cutter, and preferably to the member 4 thereof, by bolts 11 or the like, is an inclined handle member 12, which may consist of a length of pipe having a flattened end portion for attachment to the cutter. The heads of the bolts 11 are countersunk in the k nder face of the member 4, as best appears in 1g. 2. I By forming the cutting edges 6, 7 and 8 of the described reentrant V-shape, they have been found to exercise their function with much less applied effort than would otherwise be required. The ease with which the edges 7 and 8 function being proportionate to their incline, it has been found advisable to incline the lower edges 8 at a greater angle, to thus overcome greater resistance encountered by these edges due to their acting at a greater depth. For the same reason, the angle of inclination of the edges 6 is substantially that of the edges 8.

The member 5 has a vertical extent considerably exceeding that of the member 3 for the reason that many lawns rise consider ably higher than the walk to which they are adjacent.

The described cutter is inexpensive in construction, simple in operation, and is adapted to very neatly and uniformly produce the desired trench in the margin of a lawn adjoining a walk.

While it is apparent that the illustrated embodiment of my invention is well calculated to adequately fulfill the objects and advantages primarily stated, it is to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.

What I claim is:

1. A lawn edging cutter fashioned from a single metal plate, and comprising a horizontal cutting member having a reentrant V-shaped cutting edge, a vertical cutting member rising from a lateral margin of said horizontal member, and also formed with a substantially V-shaped cutting edge, a guide member rising vertically from the other lateral margin of said horizontal member, and a second guide member laterally projecting from the top margin of the first-mentioned guide member.

2. A lawn edging cutter fashioned from a single metal plate and comprising a horizontal cutting member having a reentrant V-shaped cutting edge, a vertical cutting member rising from'a lateral margin of said horizontal member and having reentrant convergentupper and lower cutting edges, the lower t which is more acutely inclined than the upper, a guide member rising vertically from the other lateral margin of said horizontal member, and a second g u-idemem- 1 her laterally projecting from the top margin of the first-mentioned guide member;

In testimony whereof I. sign this speeifieation:

' EDWARD J. GASSE-
