JEROME A. SHROOK, OF GOSHEN, INDIANA.

HAND GARDEN -CU LTIVATO R.

SPECIFICATION forming part of Letters Patent No. 410,774, dated September 10, 1889.

Application filed March 13, 1889.

To aZl whom it may concern:

Be it known that I, JEROME A. SHROCKfa citizen of the United States, residing at Goshen, in the county of Elkhart and State of Indiana, have invented certain new-and useful Improvements in Hand Garden-Cultivators; and I do declare the following to be a full,

such as will enableothers skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in hand garden-cultivators; and it has for its object to generally improve upon the construction, cheapen, and render more durable an d efficien t in operation this class of devices. The further and immediate object of this invention is to provide a hand-cultivator of this description which may be easily constructed or repaired by a person of ordinary skill, and without necessitating the use of expensive tools or machinery.

To the above end, and to such others as the invention may pertain, the same consists in the peculiar combination, and in the novel arrangement and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a handcultivator constructed in accordance with my invention. Fig. 2 is a central longitudinal vertical section of the same. Figs. 3 and 4 are detail views showing the wires forming the teeth of the cultivator removed.

Reference now being had to the details of the drawings by letter, A designates the handle of the tool, which may be of any desired size or length; but it is preferably of a size corresponding withthat of an ordinary hoe-handle.

B and 0 represent the wires forming the teeth or prongs of the cultivator.

As shown in Figs. 3 and 4 of the drawings,

Serial No. 303,152. (No model.)

the wire G is bent so as to form an elongated loop, the opposite sides of which are parallel, and the free ends of the wire are bent at substantially right angles to the general direction of the wire, thus forming the teeth 0 of the cultivator. The wire B is bent so as to form the loop B in all respects similar to the loop 0, formed inthe wire 0, and in all other respects the contour of the wires 0 and B are alike, excepting that in the wire B, atapoint substantially midway between the loop B and the free end of the wire, as at d, the portions of the wire forming the opposite sides of the loop are bent-outwardly at a slight angle, as shown, and for purposes which will presently appear.

The end of the handle A, at which it is proposed to attach the teeth of the cultivator, is provided with an opening E, and the end of the handle surrounding said opening is protected by a thimble or ferrule F, as is common in this class of tools.

The wires having been bent into the form shown in Figs. 3 and at, the loops B and C are inserted within the opening E in the handle, and a block or wedge 11 driven in the opening in the end of the handle, said block or wedge being preferably formed at its inner end with transverse grooves, as shown, to receive the said loops. The wedge or block is driven against the loops, and the transverse pin G is then driven through the handle and through the block or wedge to prevent the wedge, and consequently the wires, from being pulled out of the handle whenin use. It will be seen that when the wires have been placed in position, as described, the wire C (the free ends of which form the teeth 0 forms the inside teeth of the cultivator and the wire B the outside teeth, the outward bend at d in said wire serving to separate the teeth B a sufficient distance from the teeth C It will be at once understood that in carrying out my invention it will be necessary to use a heavy wire, and that the wire should 5 be of suitable material and properly tempered. It will be also understood that the number of teeth may be varied at will by simply increasing or diminishing the number of wires used, for while I have described and 100 shown a tool provided with four teeth I do not wish to limit myself in this application to any specified number of teeth.

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

1. lhe combination, with the handle having an opening formed in one of its ends, wires B and C, having their free ends bent to form the teeth of the cultivator and their eenters formed with a loop, as described, of the trans verse pin G and block or wedge II, for securing the said looped portions of the wires within the opening in the handle, substantially as and for the purpose specified.

2. The combination, with the handle having JEROME A. SIIROCK. Witnesses:
