To 1J/, whom it mary concern: l

BetknownthatLEUsnNE C. Jnwurtnaciti- Zen of the United States, residing at Eaglegrove, in the county of lVright and State of Iowa, haveinvented certain new and useful Improvements in Spades; and I do hereby declare the following Ato be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to spades, and more particularly to that class of devices of this character technically' known as skeleton spades.

The object of the invention is to provide a spade which is constructed of forged metal and of two parts-to wit, a head and a bit-- each of which is formed in a single piece and the two adapted to be welded together at points where but little strain is received during the use of the tool.

Another Objectis to form the body of the spade of tines which are of a peculiar construction, whereby the spade can be readily inserted into the ground and will stand any strain to which it is subjected in ordinary usage.

A still further object is to provide tines which are shaped in a peculiar manner so that their size can be reduced without proportionately reducing their strength.

WIith the above and other objects in view the invention consists of a head having tinesections extending from it, said head and sections being formed of a single forging and adapted to be. welded to abit having tine-sections extending from it. W hen the two parts are assembled, the tines are continuous from the head to the bit and taper toward the bit, they being of greater thickness at the head than at the bit. The central tine is tapered in cross-section from front to rear, so that a great saving of metal results without in any In said drawings, Figure l isa front elevation of a spade constructed in accordance with my invention. tion therethrough with the handle removed, and Fig. 3 is a section on line 3 3 of Fig-2.V

Referring to the figures by numerals of reference, l is a head having preferably three tine-sections, two extending therefromf-one at each end and one at the center. These sections and head are formed of a single forging, and a shank 3 extends fromthe center of the head and is adapted to be secured within one end of a handle 4 in any suitable manner. The bit of the spade consists of a sharpened blade from which extend tine-sections 6. These sections are located at the end and cene ter ofthe blade and are adapted to be welded to the sections 2 at points between the centers of the completed tines and the head l. lThe spade receives less strain at this point than any other, and there fore by welding the parts at these points the strength of the spade is not impaired by constructing it in the manner herein described.

By referring to Fig. 2 it will be noticed that the tines are thicker at the head than at the blade. By tapering them in this manner the blade can be forced into the ground more readily than where they are of the same thickness throughout their lengths.

Fig. 3 shows that the central tine has beveled sides which taper from front to rear. Atine constructed in this manner permits the saving of considerablemetal without reducing the strength of the tine.

In the foregoing` description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without l departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A skeleton spade formed of two parts and consisting of a head having integral tinesec tions and a sharpened blade having integral l tine-sections, the tine-sections of the head and ways reducing the strength or efiiciency of the i tine. l rlhe invention also consists in furthernovel construction and combination of parts, herey inafter more fully described and claimed.

In the accompanying drawingsI have shown the preferred form of my invention.
