UNITED STATES PATENT OFFICE,

JOHN MCCOY, OF APPLE VALLEY, GEORGIA.

CU LTIVATO R.

SPECIFIGAJZION forming part of Letters Patent No. 722,319, dated March 10, 1903.

Application filed July 3. 1902. Serial No. 114,263. (No model.)

To all whom it 777/012] concern.-

Be it known that I, JOHN MCCOY, a citizen of the United States, residing at Apple Valley, in the county of Jackson and State of Georgia, have invented certain new and useful Improvements in Cultivators; and I do declare the following to 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 improvements in cultivators; and its object is to provide a machine of this character which is strong and simple in construction, inexpensive of production, efficient and durable in use, and in which the shovels or plows may be easily and quickly adjusted both longitudinally and angularly toward and from the beam to vary the space between the shovels for diderent classes of work.

With the above and other objects in view, which will readily appear as the nature of the invention is better understood, said invention consists in certain novel features of construction and combination and arrangement of parts, which will be hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of my improved cultivator. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical cross-section through the beam and perforated locking-plate looking toward the shovels.

Referring more particularly to the drawings, the numeral 1 denotes the main beam of my improved cultivator, provided with the usual handles 2 at the rear end thereof.

3, 4, and 5 denote shorter beams, which are formed with slotted standards 6, to which the shovels or plows 7 are bolted or otherwise secured. The beams 3 and 5 are arranged on either side of the center beam 4, which is rigidly secured beneath the main beam 1 by the bolts 8 and 9. The said side beams 3 and 5 are of different length, one being shorter and the other longer than the central beam 4, so that the shovels will not lie in the same plane at right angles to the main beam 1. The rear ends of these shorter beams are connected together by the diagonal connecting bar or brace 10, which is pivoted to the under side of the main beam by the bolt 8. The

outer ends of this bar are provided with a series of apertures 11, adapted to receive a bolt 12, which secures a clip 13, slidable upon the side beams to said bar. These clips 13 securely hold the side beams, and by changing their position upon the bar 10 the beams and shovels may be adjusted angularly toward and from the main beam.

In order to adjust the side beams longitudinally,I provide them with downwardly-bent ends 14, adapted to engage the apertures or openings 15 in a looking or connecting plate 16, secured to the under side of the forward portion of the main beam by the bolt 9, and the upwardly-bent arms 17, formed integrally on each end of said plate and engaging the sides of the beam 1. A series of said a'pertures 15 is formed in said locking-plate on either side of the main beam, and by placing the forward bent ends of the side beams in the same the said beams may be adjusted longitudinally.

Owing to the fact that the connecting-bar 10 is pivoted, the side beams may be adjusted both longitudinally and angularly toward and from the center beam at the same time by loosening the bolts 12 to allow the side beams 3 and 5 to slide in the clips 13 and swinging the diagonal bar 10 to make a greater or lesser angle with the main beam. By this construction it will be seen that I am able to obtain a very wide range of adjustment for the shovels or plows and that the same are very simple, strong, and inexpensive.

From the foregoing description, taken in connection with the accompanying drawings,

it is thought that the construction, mode of operation, and advantages of my improved cultivator will be readily apparent without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention. 7

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

1. In a cultivator, the combination with a main beam; of a perforated locking-plate secured thereto, side beams having a longi- ICO tudinally-adjustable connection with said plate at their forward ends, a pivoted connecting-bar secured to said main beam, and clips connecting said side beams to said bar, substantially as set forth.

2. In a cultivator, the combination with a main beam; of a perforated locking-plate secured to said beam, side beams provided with bent ends adapted to engage the perforations in said locking-plate, a diagonal connecting-bar pivoted to the rear of said main bar, and clips slidable upon the side beams and adjustably secured to the connecting-bar, substantially as and for the purpose described.

3. A cultivator comprisinga main beam, a perforated locking-plate secured to said beam and formed with integral arms engaging the nesses.
