Application filed June 19, 1915. Serial No. 35,025.

This invention relates to hoes, particularly to that class made of sheet metal. The object of the invention is to produce an article of this character that will be strong, durable, capable of resisting strains of rough usage and inexpensive to construct. The salient features of the invention are examplified by reference to the accompanying drawings, in which- Figure 1 is a central vertical section of a hoe head embodying the essential features of my invention and showing a handle applied thereto. Fig. 2, a face view of the socket member. Fig. 3, a face view of the flat blade; and Fig. 4, a sectional view of parts ofthe blade and socket member, taken at right angle to the blade on line 4:, 4., Fig. 1.

The blade 5 is formed from a right angular sheet of metal, as steel having hardening characteristics such as is commonly used for this purpose. At the upper central edge a circular opening or recess 6, which may be about one-half of a circle, is formed. Extending downwardly from such circular recess the metal of the blade is embossed, corrugated or otherwise raised toward the face of the blade by suitable pressure means, such as stamping dies, and the metal which originally occupied the space within the part circle thatforms the contour ofthe central recess 6 is forced or pressed into a projecting flange 7 surrounding said recess, the axis of said flange being at an angle to the plane of the blade. The raised or corrugated portion of the blade beneath the central circular opening partakes somewhat of the form of a pear shaped embossment 8, the narrow or neck part 9 of which extends some distance down into or along the central part of. the blade. This embossment and the formation of the flange 7 that extends from the central recess, formed in or on theenlarged part of the pear shaped embossment,yimparts strengthandrigidity to the blade without being raised or forced beyond the plane of the blade to an extent that would disrupt or weaken the metal when the blade is made of a suitable steel'havin'g'the requisite hardness to meet thorough usage to which the hoe is to be submitted. This part of. the blade is re-inforced as hereafter described.

Sheet steel hoe blades should have a comparatively high percentage of carbon to afford the necessary hardness and wear-resist,

ing qualities. It has been found that when the body of the blade is disturbed to any considerable degree, by embossing-corrugatmg or otherwise forming it the metal may be weakened to such anextent that the blade is liable to be disrupted by use although such weakening of the metal may not be apparent on inspection of the blade after formatlon. To meet this difliculty, this lnventlon provides that the other part or socket member ofthe hoe is also made of sheet steel, and as the sheet blank therefor has to be considerably distorted informing it into the desired shape a decarbonized or soft steel is used for this purpose. The socket 10 of this member is made cylindrical in form, or preferably conical as shown in Figs. '1 and 2, the seat in which the handle 11 is to be inserted being open at both ends. If of conical form the large end of the socket is at the front end of the seat, so that the handle, which is, correspondingly tapered and passed into the seat from the front of the blade, is-securely held therein to resist dragging strains. The socket has-a single lap seam 12 at its upper side.- Pins 13 may be inserted through the handle and socket to securely hold the-parts together. The socket member hasat itsfront end a downangle to the axis of the socket and raised or corrugated at its central part, thus forming an embossment 15-adapted to fit in the em- -D sAsrATENr orrion'. f

wardly extending plate 14 arranged at an s v bossment 8, 9 ofthe blade. The boundary portion of the plate 1 L constitutes a flat flange 16 surrounding the embossment 15 andextending therefroma considerable distanee in all directions; this flange seats shown at Fig. l and adequately secured toto the sockets axis.

An examination of the two parts "of the hoe, made as described and shown at Figs. 2 and 3, indicates that there are no weak points or parts that are liable to derangement and that when they are assembled'as gether, each part reinforces the other, thus producing an. article of finished appearance and of maximum strength for the amount of metal used in its structure. It will be observed that the juncture of socket 10 and plate 14 is an unbroken continuous bend whose plane is at an angle to the sdckets axis and includes one-half, the circumference of the socket. In other words, this plane liesin a semi-ellipse whose minor radius equals that of the outside dimension of the large end of the socket and the major radius equals. the angular distance between the cen tral part of the juncture and the center of the socket at its large'end.

The blade and socket member may be 'fas-c tened together by any suitable means, the preferred connecting means being by the welding process known as spot-welding, as indicated by themarks 17. The locations for such welding may be selected at pleasure, as for instance, the spots indicated in Figs.

. 2 and 3. The edges of the socket 10 which form .thelap seam 12 may also be secured together by spot-welding.
