\rvm W. Hades INVENTOR ATTORNEY Patented Jan; 2?, 1931 UNITED. STATES IRVIN w. HALEY, or scoTIA, NEW YORK EDGE TRIMMER ron- LAWNS Application. filed February 21, 930. Serial No. 430,396.

This invention relates to devices for-cutting or trimming lawns at the edge of side walks and particularly to devices'of this character which are so designed as to cut clowna ward on the inner face of the pavement and form a slight depression orv ditch extending entirely along the sidewalk, trimming the grass back to the edge of the ditch.

One of the objects of the present invention is to provide a device of this character in which the handle can be set at any desired angle with relation to the lawn cutting memher or reversed to cut right or left without changing the blade.

Another object is to provide a flange extending over the sidewalk and acting as a depth guide, this flange carrying rollers bearing against the upper surface of the sidewalk.

Another object is to providea device of this character with a mold board as it may be termed disposed in the blade, which blade is U-shaped in cross section, so as to throw the dirt and sod cut by the blade upward and out of the trench.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing, wherein Figure 1 is a front elevation of a tool constructed in accordance with my invention;

Figure 2 is a side elevation thereof;

Figure 3 is a detailed sectional view on the line 3-3 of Figure 1.

Figure 4 is-a fragmentary top plan view of the blade of the tool detached, the rollers being omitted to show the slots.

Referring to these drawings, 2 designates the shank having a handle in the form of a cross bar 3 held in place by a strap 4:. The

* lower end of the shank is reduced in thickness to receive the two metallic straps or bars 7 which are held to the shank 2 by means of bolts 6, these straps or bars being diverg ently inclined downward with relation to each other. The blade 1 of this tool, as shown in Figures 1 and 2, is approximately U- shaped in cross section, the inside wall of the U extending straight downward and the outside wall of the U extending upward and out ward; The inside wall of the blade is formed with an outwardly extending flange 9 and with an upwardly extending medially disposed lug 9a through which a bolt 8 passes, this belt extending through the two straps 7 and through the outer "wall of the blade 1. This lug may be formed in 'a variety of ways, as for instance, by cutting out the flange in the form of the lugand turning the lug up from the material of the ii an ge' 9 as ill ustrat-ed in Figure 4.

The inside wall of'the blade 1 is formed with the outwardly projecting flange 9 which is adapted to extend over the pavement or over acurbing such as is used with walks or paths and preferably this flange 9 is slotted 5 at 10 and disposed in these slots are the rollers 11. Two of these rollers are preferably used.

It will be seen that by releasing the nut or bolt 8, the handle can be adjusted to any desired angular relation to the blade so as to permit the blade to be readily pushed in either direction either with the flange 9 on thelright hand side or left hand side of the too V i Disposed within the U-shaped blades is a mould board 12 which isdouble so that it extends upwardly from both ends to the middle of the blade and acts to discharge the dirt and sods cut out by the blade laterally on to the surface of the ground. This mould board at its middle arches over the bolt 8 and is held in place by a bolt 13 extending through the mould board just below the apex and beneath the bolt 8. It will be 35 obvious that this mould board will act without relation to the directionin which the blade is moved and whether the blade is pushed or pulled. The mould board is readily removable if it be desired to remove it or as readily put in place. 1 l

This tool permits the userto keep the dirt cleaned out around the sidewalks at all times of the year. It is very simple, it has been found tho-roughly effective in practice and, as before remarked, itis so designed that it may be pushed in either direction.

I claim 1- V 1. A lawn edger of the character described,

comprising a handle shank, irons attachedto 10C the handle shank and extending downward below the same and spaced apart at their lower ends, a blade approximately U-shaped in cross section, a bolt passing through the opposite walls of the blade at the middle thereof and adjacent the upper edges of the blade and passing through said irons, said bolt when tightened, holding the blade in any angularly adjusted position, and a double mold board disposed within the blade having its middle portion raised to-diseharge dirt over the upper edge of the blade.

2. A lawn edger of the character described, comprising a handle shank, an approximately U-shaped blade operatively mounted upon the lower end of the handle, the blade having a straight downwardly extending wall and a wall curving upward and outward toward the other side of the blade, a transYQI'se bolt holding the blade in place on the handle, and a mould board formed to provide two upwardly and medially inclined wings and arching orer said bolt, and a bolt passing through the wings just below the first named bolt for holding the mold board in place.

In testimony whereof I hereunto allix my signature.

IRVI N W. HALEY.
