4 To all 'whom it may concern:

- Beit known that I, EDWARD SENN, a citizen of the United States of America., residing at Birmingham, in the county of Jederson and State of Alabama, have invented certain new and useful Improvements in Hoes, of which the following is a specitlcaf tion.

My invention relates to improvements in f hoes and has for its object to .improve` the hoe which is described in Letters Patent No. 922,202, issued to me' on the 18th day of May., 1909.

@ne object of my invention is to strengthen the neck of the hoe, which connects the blade and socket portion, by a corrugation which extends along the vertical center line of the neck andmerges into the` blade and socket portions of the hoe blank at oints spaced from the neck.

further object of my invention is to strengthen the neck by tapering the inner ends of the notches or slots on each side of the neck to increase the amount of metal available at that point to be bent or folded inwardly about the corrugatedneck portion to reinforce it.

- ,A further object is to compress the double trated'in the accompanying drawings forming a part of this specification, and in which :V-v

Figure 1 is a plan view of the hoe blank.

Fig. 2 shows the blank with the reinforcing corrugation impressed therein and the socket partly formed. Fig. 3Y is a front elevation of the nished hoe. Fig. 4 isa side elevation of the hoe. Fig. 5.is a rear ,elevation of the hoe. Figs. 6 and 7 are cross sectional views through the neck of the hoe taken on the lines .fc-w and Ja-fg, respectively, of'

con, is forme from the blank shown in Fig.

1, 'and which comprises the blade 1 and a. f

neck. portion 2 which connects the socket portion =3 to the blade. It will benoted that the -inner ends of the slots 4, which space wings 5 on the socket portionfrom the blade, are not rounded, as in the case of my former patent,but are tapered to a point in the plane of the top line of. the blade, therebyprovlding excess metal 6 `which strengthenshthe neck'.

h corrugation or rib 7 is formed by in-` dentmg the rear face of the hoe blank, the corrugation starting in gradually in the upper central portion of the blade 1 and continumg along a vertical center line across the neck 2 and terminating in a widened rounded depression which, disappears about themiddle of the socket portion 3. Where this corrugation crosses the neck proper it extends practically across the whole neck so that the cross section of ythe neck, where it joins the blade, is substantially V-shaped. When the blank is thus corrugated, the two wingsv 5 are bent rearwardly into substanxtial parallelism and the socket portion 3 is bent at the desired angle to the blade. The socket is next formed by dies which curve the wings in transverse cross sectionl and squeeze the top edges of the wings together which 'causes the center of the section 3 at its top to be creased at 8 to bring its edges on each side of the Vertical center line together. The metal portions 6 of the neck are given a twist and folded inwardly against the adjacent sides of the V-shaped neck and the neck is then slightly crimped by forcing the overlapping folds of metal forming the reinforced neck inwardly from each side which gives a compact, rigid and short neck that is amply strong enough for the hoe. By the neck l mean that portion of the blank which serves as a connection between the blade and socket portions and such neck .being formed between the f1 teral slots a vtheir inner ends tapered y a slightly curved top line as shown or by a straight line at an acute angle to the top line of the blade, or such slotsv may be cut with their side walls approaching atany desired curve or angle but l prefer to have the slots leave suicient metal at the points 6 so that 1t can be folded over and crimped against the corrugated neck to give .it the maximum strength to withstand'all strains on it.

con

' shaped and twisted to form a socket.

' is folded over and In Figs. 8, 9.and 10, a double ended hoe or tool is shown, the blank here providing a central socket' portion 10 connected by neck portions 11 to differently shaped

blades

12 and 13. The socket portion has wings 5, as in the case of Fig. 1, and these wingsrlae e corrugation 14 for strengthening the neck extends entirely across the socket portion 3 and necks 11 into the blade portions.

The Wings -5 are perforated to receive screwsor rivets 15 by means of which the hoe is fastened to the handle 16. Other fastening means may, however, be employed.

My invention is equally applicable to the manufacture of tools similar to hoes and my claims are intended to apply generally to such tools.

What l claim as new and desire to secure by Letters Patent, is

1. As an article of `manufacture, a hoe' comprising a blade, socket portion and a relatively narrow portion connecting the blade and socket portion, all formed from a blank which has a vertical corrugation extending from the blade across the connecting portion into said socket portion, the sides of said narrow portion of the blank adjoining the socket portion being twisted to engage and reinforce the corrugated connecting portion.

2. As an article of manufacture, a hoe formed from a blank comprising blade ano. socket portions connected by a relatively narrow corrugated neck, said neck increasing in width toward the socket portion to provide side portions thereof adapted to be bent inwardly on each side against the convex wall of the neck to reinforce it, substantially as described.

3. As an article of manufacture, a hoe formed from an integral blank having blade and socket portions connected at their centers and spaced at their sides by lateral slots, said blank being indented to form a corrugation which extends part way into each of said portionsand continues across the metal connecting said portions, giving. it substantially a V-shaped horizontal cross section, and wings on the socket portion which are shaped and twisted to form between them a socket and' which have each a portion that ressed against the expressed walls of said V-shaped connecting portion to reinforce it, substantially as described.

4. As an article of manufacture, a hoe or like tool formed entirely of pressed metal, the hoe comprising a blade, a socket portion and a relatively narrow neck portion connecting said blade and socket portion and formed by slots which lead inwardly from opposite points in the sides and taper at their inner ends, a corrugation which extends from the blade vertically and centrally across the neck'into the socket portion, and portions of the metal in the socket portion which are adapted to be bent together to form a socket and pressed against the offset walls of the indented neck to reinforce it, substantially as described.

5. As an article of manufacture, a hoe or like tool formed entirely of pressed metal, the hoe comprising a blade, a socket portion and a relatively narrow neck portion connecting said-blade and. socket portion and formed by slots which lead inwardly from opposite points in the sides and taper at their inner ends, a corrugation which extends from the blade vertically and centrally across the neck into the Socket portion, and reinforcing portions of metal left near the juncture of the neck and socket portions which are bent inwardly over and crimped against the expressed sides of the corrugated neck to reinforce it.

6. A hoe comprising a blade and a socket portionl formed from a blank which has lateral slots cut from opposite points inwardly to points near the vertical center line of the hoe, said slots having their inner Walls cut at an incline to leave between them a neck portion which flares from the top line of the blade tothe point of juncture with the socket portion to provide excess metal to reinforce the neck, a corrugation which extends centrally across said neck portion, the sides of the socket portion being bent and shaped to form the socket and said excess metal of the neck being folded against the convex sides of said corrugation to reinforce it, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.

EDWARD SENN.
