IMPROVED CULTIVATOR A-ND HARROWQ I Specification forming part of Letters Patent No. 416,274, dated February 7, 1865. d

To all whom it may concern I Be it known that I, THOMAS Snorer, of Fairmount, in the county of Vermillion and State of Illinois, have invented a new and Improved Gultivator and Harrow Combined 5 and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings,- making part of this specification, in which- Figure 1 is a plan of my improved machine in condition for cultivating. Fig. 2 is a vertical longitudinal section of the same in the line 00 m, Fig. 1. Fig. 3 is a rear end elevation, representing the machine in condition for use as a harrow.

Similar letters of reference indicate corresponding parts in the several figures.

In this machine a novelarrangement of devices is provided to facilitate the vertical adjustment of the shovels to avoid obstructions, and in addition to this feature the cultivatorframes are provided with harrow-teeth, and the frames are adapted to be reversed in such manner that the said teeth may be presented in a downward direction, so as to convert the implement into a harrow when desired, all as vill be hereinafter fully explained. In order that others skilled in the art to to the turning of the machine and thus avoid injury. The entire weight of these frames 'is supported by the shovels E, which are thereby pressed the requisite depth into the ground, the frames being attached to the forward ends of the side pieces, A A, by means of clevises d (I, one on the forward end of each frame D, coupled with a bracket or clevis, a, secured on the end of the respective pieces A. Theclevises a a are secured by screws to, which may be readily withdrawn to admit of thedetachment of the clevises a, when the frames D D are to be reversed, inithe mannerhereinafterexplained. Onthe side of each cultivator-frame, opposite that from which project the shovels E, are teeth or prongs F, rigidly inserted into the frames.

- From the respective frames D D rise stand- 7 ardsGr G, which are secured andretained in upright positions by having their extremities tenoned to enter corresponding mortises formed for their reception in the frames D. .These standards are provided with apertures or slots in which rest bars H H, which fit loosely in order that the slots in the standards may be slid to any desired position thereon for the purpose of adjusting the frames D D with relation to each other. To effect this adjustment of the standards G G pins 9 g are employed, these pins each being passed through the desired aperture of the series h in the bars H H, and through corresponding apertnres'in the standards G. This adjustment is either to bring the shovels in the best position for operating around the growing plants, or to bring the frames in contact with each other when the implement is to be employed as a harrow. It is designed to have mortises on both sides of the frames D D to accommodate the standards in either position thereof.

1 I represent what may be termed treadlelevers, the same being suspended centrally upon strong metallic loops JgJ, inserted into the bar A at the under side thereof. To the rear ends of the treadles I are attached cords, wires, or rods i i, which extend from and are connected with the frames D. These treadles I, while forming convenient foot-rests for the driver, afford ready means for enabling him to elevate the frames D,either when the shovels E or teeth F are presented to the ground.

When it is wished to adapt the machine to perform the functions of a harrow it is only necessary to remove the adjusting-frame G H, detach the clevises a in the manner described, substitute the frames D, one for the other, reattach them with the teeth F presented downward, and remount the frame G H.

Having thus described my invention, the following is what I elaim as new-therein and desire to secure by Letters Patent:

1. The frames D D, provided with shovels and connecting rods or wires i f r .adj usting E and teeth F the'clevises a d, and screws or the frames D D, substantially as explained. bolts a, in combination with the adjusting- The above specification of my improved culframe GH,the1atter permittingthe cultivatortivator and harrow combined signed this 20th frames to be operated simultaneously or indeday of June, 186-1. I pendently, and adapting said frames, when I THOMAS SHORT. used as a barrow, to be brought together at Witnesses: their rear ends, as herein specified. CHARLES 1). SMITH,
