Abstract:
Disclosure is made of a garden hoe tool, having an adjustable pitch head, to control the depth of the dig into the soil, and the head comprising a tool base blade and vertical sides on the base blade and a compression V spring to lock the pitch of the head, as adjusted.

Description:
This invention relates to a garden hoe tool having an adjustable pitch head the purpose of which is to control the depth of the dig into garden soil. 
     BACKGROUND OF THE INVENTION 
     This invention relates to a manufacture, as an adjustable pitch garden hoe, wherein the pitch of head assembly can be adjusted to control the dig or bite into the soil. To date the usual garden hoe has a fixed head that is not adjustable thus the dig or bite into the soil cannot be easily controlled.

     DETAILED DESCRIPTION OF INVENTION 
     The description which follows discloses, as a manufacture an adjustable pitch garden hoe tool of a handle 1, to which is attached ferrule mount segments 2, 2&#39; and ferrule legs 11, 11&#39; attached to the mount segments 2, 2&#39;. The adjustable pitch segment of this garden hoe tool head 16 is an assembly of a base blade 6, and two vertical sides 5, of base blade. The base blade 6, and vertical sides 5, 5&#39; is a unitary or single unit garden hoe tool head 16 and 5&#39; is adjustable for the variable pitch of base blade 6. The vertical sides 5, 5&#39; attached to base blade 6 are mounted on the ends of ferrule legs 11, 11&#39; by means of bolts 12, 12&#39; extending through matching holes in the ferrule legs 11, 11&#39; and vertical sides 5, 5&#39;. The bolts 12, 12&#39; act as the pivot point in adjusting the pitch of the hoe tool. 
     To lock the adjusted pitch of the hoe tool head 16, a modified compression V spring 10, having elbows 3, 3&#39; fitting into slots 13, 13&#39; in ferrule legs 11, 11&#39;, and arms 9, 9&#39; of V spring legs 15, 15&#39; fitting into holes 18, 18&#39; in the end of ferrule legs 11, 11&#39; and the arms 9, 9&#39; extending aligned variable pitch set holes 4, 4&#39; as desired. 
     The V spring 10 is mounted between ferrule legs 11, 11&#39; with elbows 3, 3&#39; extending through slots 13, 13&#39; in the ferrule legs 11, 11&#39; and the arms 9, 9&#39; extending through holes as described above, to lock the pitch as adjusted. 
     The V spring 10, shape preferred has a spring coil base 8, and this spring is mounted with the apex , or spring coil base 8 at the apex of the ferrule legs 11, 11&#39;, and on being so mounted the spring 10 is held in position by the elbows 3, 3&#39; and arms 9, 9&#39; mounted as described above. 
     The hoe tool head 16, is formed of hoe blade base 6, and vertical sides 5, 5&#39; The hoe blade base 6 is of a modified V shape, with the protruding apex in the front, (see FIGS. 1 &amp; 2), and the concave apex in the back. 
     The elbows 3, 3&#39; of V spring 10 extend outward further than arms 9, 9&#39; of V spring legs 15, 15&#39; such that on squeezing inward the V spring elbows 3, 3&#39; when mounted in slots 13, 13&#39; in ferrule legs 11, 11&#39; the arms 9, 9&#39; are withdrawn or forced out of aligned holes 4, 4&#39; of vertical sides 5, 5&#39; of base blade of hoe tool head 16 thus allow for changing the pitch of the hoe tool head 16, as it pivots on the fastening pivot bolts 12, 12&#39;. 
     Referring now to FIG. 5, the V spring 10 has elbows 3, 3&#39; and arms 9, 9&#39; extending outward and the apex of the V spring is a spring coil base 8 of approximately one revolution for better spring action as desired. 
     The compression V spring 10, has on each leg 15, 15&#39; an elbow 3, 3&#39; respectively, extending outward at a midpoint between the apex 8 and the end of each leg 15, 15&#39;, and at the end of each leg 15, 15&#39; of the v spring, an arm 9, 9&#39; extending outward. When v spring is mentioned this means compression V spring. 
     To make for easy use of the above described apparatus, the edges of the vertical sides 5, 5&#39; and the front edge 7 and back edge 14 of the garden hoe tool head 16 are sharpened to a desired cutting edge.
