ro ALL WHOM 1r MAY coNcEaN;

Bc it known that I, WILLIAM T. CLEMENT, of Northampton, in the county o f Hampshire, and State of Massachusetts, have invented certain new and useful Improvements in the Manufacture of Hoes; and I do hereby declare that thc following is a full and exact description thereof.

My invention relates to that class of hoes which receive the 'handle wit-hin a socket or eye open atboth-ends. It includes most ofthe several varieties of'stnb-hoes, planters hoes, and those hoes, under various names, which are used in very heavy work. The eye requires to be long, so as to afford a yery firm hold on the handle, which is fitted tightly therein, by wedgin-g or otherwise., A dilhculty is experienced in making eyes of suliieient length, without a vcr'y great expense in'the forging. Several plans have been proposed, and patents have been taken for welding, braaing, or otherwise attaching oyes separately, formed usually of cast iron ;v but these have all heen'more or-less open to object-ion.

My invention overcomes most o f the d'iiliculty, allows the hoc to be produced very light and strong, and at` I will rst describel what I consider the best means of carrying out my invention, and will afterwards designate tho points which I believe to ben-ew. The-accompanying drawings form a part of this specication.

Figure lis a. side view, and v Figure Zarredge viewof the tube or socket B, without the iiange or lip B. Figure is asido.view,'and v l i Figure 4 an edge or face view of the saine after the'lange is produced.

Figure 5 isi-thc blade, cut or formed to the proper outline,'hefore the place for the eye is prepared. Figure is a face View of the blade prepared.

'Figure is a longitudinal vertical section through-the same.

Figure `8 is a longitudinal vertical section through the b lade A and 4tube B, after boing applied together.

Similar letters of reference indicate like parts in all the iigures. A is a blade of steel, or of wrought iron, or of the two materials soldered together in the ordinary manner.V It may beproduccd by forging, rolling, or otherwise, and may be of uniform thickness. iA is a broad lip, which is turned up by hand or otherwise, while that edge of the blade A is at a high temperature. It is curved to match the inner surface of the eye. A good form is indicated in the drawings. Ordinarily the edge will he less regular and smooth than is here represented. I prefer to draw the extremo edge very thin. v' lhis lip stands at the same angle, relatively, tofthe plane of the blade A, as the handle is designed to stand in the hoe. B is a tube of wroughtfiron.. It may be lap-welded or butt-welded, such as is formed for gas-pipe, or it may be produced in any other convenient' form which will allow itscheap and uniform production from wrought iron. B1 is a broad flange or lip, turned up on onc side, and drawn to a. thin edge, as represented. rIhis flange stands at the same angle, relatively, to the axis of the tube B, as the blade of the hoo is intended to stand relatively to the handle. The parts A A' and B B are now applied together and welded in the position indicatcdin iig. 8,' and if the edges of A and B have been previously made thin, the eye is finished smoothly and perfectly, with very little labor. The metal in my eye stands without strain, and there ,is a just sufficient thickening of the material at the points of junction between the eye and the blade, to afford requisite strength. I can, by properly modifying the sizes, it the parts -B B inside, instead of outside of the part Af, if preferred..

Having new fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows:

I claim th within-descrbed method of manufacturing hoes, consisting in the production of wrought-iron eyes B B', and previously-prepared blades A A', and in welding them together in thc manner substantially as herein set forth.

'W. T. CLEMENT.
