LAWN-Enema IMPLEMENT.

Application filed April 19, 1927. Serial No. 184,933.

The present invention relates to an improved gardening toolwliich is better known in the art as a lawn edging implement, that i -is, a device which is'adapted fortrimming the edge of a lawn ad acent the concrete sidewalk for the purpose of making the lawn edge straight and providing a drainage guttrimming or edging device which is madein the form of an excavating shoe provided with one straight side and one inclined side to facilitate movement and excavation.

device and which regulates the depth of the cut.

A further feature is the novel connecting 0 arch between the shoe and the shank.

Other features and advantages of the invention will become apparent from thefollowing description and drawing.

In the accompanying drawing:

as Figure 1 is a side view'of the complete implement showing the approximate method of use. I Figure 2 is an enlarged end view of the excavating device. I I to Figure?) is a side view of the shoe per se.

Referring to the drawings in detail, it will be seen that the reference character 1 desig nates theshaft which is of any appropriate length and construction. At the upper end 5 of this isa handgrip 2 mounted on a bail 3 which is connected to the shaft through the" medium of a socket 4. The socket in this instance forms a cap to fit over the end of the shaft and it is suitably riveted 5 1 fastened in place. y

At the opposite end ofthe shaft-.is a coulin or attachin device which com rises the socket 5 suitably fastened inflplace, this socket being formed with an integralshank b5 6 of square cross section. The shank is bowed longitudinally to off-set itwith respect to the Another feature of the invention is the A further feature is an adjustably mount-- ed roller which facilitates the situation ofthe longitudinal axis of the shaft audit is pro vided in its upperside with notches 7.

"The excavating device is'made up of two principal parts. First, the shoeS comprises.

a sheet metal body which is formulated to provide a straight wall 9 and an inclined wall 10 extending at an acute angle to the straight wall and being in anupper attaching portion 11 which is disposed in spaced parallelism with. the wall 9. The opposite ends of the 'bodyare bevelled to 'provide cutting-edges and to render the device reversible. The con-- nectmg portion 12 is rounded somewhat to facilitate actuation andsliding of the shoe.

The second principal part 13 comprises a single metal casting including an arch, the bight portion 1410f which is comparatively heavy and provided with a'square hole through" which the shank 6 extends.

a setscrew 15 is provided for selective reception in the notches 7. The arms 16 0f the casting are disposed in outwardly directing relation and terminate in cross heads 17' which are riveted to theside wall of the shoe. Incidentally the, straight wall'9 of the shoe is provided with avertical row of apertures 17 for selective reception of the axle 18 of asmall gauge roller 19. The axleis held in place by retaining nuts 20, arranged on opposite sides of the wall 9 as shown in Figure 2. The elevation of the roller can thereby be changed from time to time to regulate'the depth of the cut.

After carefully considering the foregoing detalled description inconnec'tion with the At this point,

accompanying drawing, it is believed that a clear understanding of the construction,

'method of assembl and the use of the in-- ventionwill be had. Also in making an analysis. of the structure, it has been particularly noted that the invention is characterized by simplicity and inexpensiveness of manufactu're, as well a-seonvenience and compactness in the arrangement of parts. These and other advantagesand featuresof the inven tion have doubtless. been made apparent. Therefore, v thought unnecessary. or otherwise vention has been shown and described, it is to be understood that minor chan'ges in shape,

size and arrangement of parts coming within more lengthy description is While the preferred embodiment of the inthe scope of the adjoiningclaims may be resorted ,to if desired.
