SPECIFICATION forming part of Letters Patent No. 362.049. dated April 26, 1887.

Application filed December 26, 18%5. Serial No. 186,828. (Nomndel) To all whom, it may concern:

Be it known that I, WILLIAM S. \VEIR, re

siding at Monmouth; in the county of Warren and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Cultivators, of which the fol lowing is a full description, reference being had to the accompanying drawings,in which- Figure 1 is a top or planview showing one side of a cultivator with the improvement attached, and showing by dotted lines the turning of the wheel from the side draft on the draw-bar; Fig. 2, a side elevation with one wheel removed; Fig. 3, a side elevation of the draw-bar and axle; spindle; Fig. 4, a top or plan view of the draw bar and axle-spindle; Fig. 5, a section on line as w of Fig. 3.

This invention relates to that class of cultivators which are known as tongueless, and

has for its object to improve the running of such cultivators in respect to the wear on the wheel-spindle in case of side draw or draft from the team turning the spindle, so that the wheel, by reason of the angle at which it is turned, will cut the spindle, making it necessary to replace the spindles in many cases; and its nature consists, in providing a draw-bar and spindle connected together and pivotally supported in abracket from the arch or frame of the machine, the draw-bar having in its forward or draft-attaching end a series of holes, by which the line of draft can be changed to give the'wheel and spindle a direct line of travel in case the animal has a tendency to pull either in or out, all as hereinafter more specifically described, and pointed out in the claims as new.

In the drawings, A represents the spindle,

center of the spindle, at the inner end in the which purpose the end of the bar is made somewhat wider than the main portion, and this bar, as shown, has a downward-curved portion, B, which acts as a brace, and at its rear end it is provided with a plate portion, B, the parts B B B being formed of a single piece in the arrangement shown, and, as

shown, the lowerrear corner has an extension, B, for the attachment of a drag-bar or runner. The plate portion B of the bar is provided on its face with a series of serrations, b, corresponding to the teeth or serrations a, so that when the two plates A B are together the serrations or teeth will interlock and prevent slipping; and the plate B has a slot, b, for the passage of the bolt or rod a, so that by passing a bolt or rod through the slot and turning down the nut a" the spindle and drawbar will be firmly locked together.

0 is a bracket attached to the arch or frame of the machine, so as to stand out horizontally, and Ga bracket or support which may be formed by turning the end of the arch at right angles to stand horizontally, or by attaching a bracket corresponding to O to the arch. As shown. in Fig. 4, the upper and lower end of the plate B is provided with a pintle, c, and with this form of construction the brackets C 0 each have a hole to receive a pintle, and thus pivotally connect the draw-bar and spindle in position. As shown in Fig. 5, the upper and lower ends of the plate are provided with a hole, 0, and with this construction the brackets are to have each a pintle to enter the hole a and make the pivotal connection for the draw-bar and spindle.

D is the frame or arch, which may be of any of the usual forms of construction; E, the plowbeams, each carrying two plows and provided with a handle, as usual, and in the construction shown the forward end of the beam is provided with a box to encircle a round portion on the lower end of the arch, and allow the necessary side swing of the beam; F, the wheels, one mounted on each. spindle A, in any usual manner; G, a clip, the rear end of which is attached by a pin or bolt to such one of the holes in the forward end of the draw-bar as required for the draft; H, a single-tree attached by a bolt or pin to the clip G. The part represented by the letters D E F G H may be made of any of the usual and wellknown forms of construction for such parts for what is known or termed tongueless cultivators, as these parts form no portion of the invention, except in being parts of the complete machine, the invention pertaining to the spindle and draw-bar, and to giving, through these parts, a correct line of draft to prevent the cutting of the spindle in case the wheels turn at an angle, or out of a direct line of travel.

In use the draw-barand spindle are secured together by the belt a, or in some other suitable manner. The spindle being adjusted at the required running height for the depth of cultivating, and with the hitch made asshown in Fig. 1, the attachment of the clip for the single-tree is in line, or nearly so, with the pivotal point of the draw-bar to the arch or frame, and with the hitch in this form the animal is supposed to draw straight without pulling in or out, giving the wheel a direct line of travel without turning; but in case the animal pulls in,so as to have a tendency to turn the wheel in the direction shown by the dotted lines in Fig. 1, the clip G is moved to such hole inward as will overcome the tendency of the animal to turn the wheel out, by thus drawing the wheel back, so that it will run true on the spindle and prevent cutting; and in case the tendency of the animal is to draw out and turn the wheel in an opposite direction from that shown by the dotted lines, the hitch is made in such hole on the opposite side of the draw-bar end as will overcome this tendency and give the wheel a direct line of travel, so that it will not cut or wear on the spindle.

It will thus be seen that if the animal draws straight a bitch is provided accordingly, and if it pulls either in or out a hitch can be made by changing the point of attachment of the single-tree in or out on the end of the drawbar to overcome the tendency of the animal to turn the wheel,by turning the draw-bar and spindle, and thus keep the wheel in a true line of travel, no matter what the tendency of the animal to draw may be.

\Vhat Iclaim as new, and desire to secure by Letters Patent, is-

1. The combination,with the spindle A,l1aving adjusting-plate A, of the draw-bar 13, provided with adjusting-plate B and having in its forward end a series of holes, 1;, substantially as described.

2. The combination of the spindle A, the draw'ba-r B, adjustable 011 said spindle and provided at its forward end with a series of holes, I), for attaching an adjustable draft device, the arch or frame D, and the brackets C O, substantially as described.

3. The combination of the arch or frame D, the brackets O G, the draw-bar B,having holes I) and adjusting-plate B, and the spindle A, having adjusting-plate A, said draw-bar and spindle being connected and pivotally supported in the said brackets, substantially as described.
