- Figure 1 is a top or plan view; Fig. 2, a side I elevation, with the wheels removed. Figs. 3
- the nature of this invention consists in an improvement in the device for connecting the drag-bars with the main frame, and moving them separately or in unison, and in the combination of parts as hereinafter more fully described, and in the devices for elevating the plows above the ground and adjusting their running depth.
- A represents the axle; B, the wheels; 0, the main frame; D, the dragbars; E, the plows or shovels, with their standards; F, the cylinders attached to the main frame U; G, the shafts passing through the cylinders; H, the elevating-levers I, the curved standards; J, the upper foot-rests K, the lower foot-rests; L, the seat; M, the seatbars or frame; N, the brackets, with a series of holes for adjusting the height of the seat; a, the cross-rod for connecting the elevatinglevers H; b, the interposed spring in said rod; 0, the openings in the sides of the curved standards; (1, the pins on the levers H which engage with the openings; f, the guards on the levers H; g, the chains for elevating the drag-bars D; h, the sheaves over which the chains g run; 11, the pins for connecting the ends of the chains 9 with the levers H; j, the rod
- axle A may be elevated, as shown, or it may be made in any of the well-known forms.
- a single tongue may be applied to the frame 0, or the bars thereof may be extended so as to form a split tongue, as desired.
- This part of the machine, as well as the drag-bars, plow-standards, and plows, may be made in any of the well-known forms, which are suitable to operate in connection with our lifting devices.
- the curved standards I are made of castiron, and may be bolted to the axle A, as shown, or to the frame 0. These standards I are made on the arc of a circle, having the pivot is for its center, and they are provided with openings c-are made oblong, so as not to require any close fitting of the pin 11.
- the levers H are pivoted to the brackets k, which brackets are usually made with a slot for the bolt which fastens them to the frame C, so that the pin 61 may be adjusted forward or back by means of said brackets.
- the chains g are connected to the levers H by the pins or hooks i, and pass up over the sheaves h, and are connected with the drag-bars D by means of the rods j.
- the chains g may extend clear to the drag-bars. The length of the chains is adjusted by engaging different links with the pin '6.
- the two standards I are connected together at their upper ends by the rod or bar I, which passes through them, and also form the bearing of the sheaves h.
- the upper end of each standard is bent over, as shown at m, Fig. 3, so as to form a guide to keep the chain on the sheave h, and to form braces between the standards and cross-rod l, which arrangement connects the upper ends of the standards firmly-together, and gives the two standards I four points of support on the cross-rod l.
- the levers H are connected together near their lower end by a cross-rod, a, which is formed 'in the middleinto a helical spring, as shown.
- a cross-rod a
- This connecting spring-bar a is located over the pivot it, but its precise location is not material, its office being to press the levers H against the sides of the standards I, so as to keep the pin d engagedwith said standards by means of the openings 0.
- the standards are connected at the top by the cross-rodl forming axles for the wheels h, and also a brace for the standards, and holding them securely in position, which is necessary where the levers have a side motion.
- the levers H are pushed away from the standards I, which disengages the pins 01 from the openings 0, when the levers can be elevated or depressed, as desired; and when in the position required the spring I) will force the pins d into the notches or openings c at the sides of the standards I and hold the levers H in position.
- the levers may be moved together or separately, as desired.
- the drag-bars D are attached to the frame 0 by means of shafts G, which pass through tubes or cylinders F.
- the lower end of each shaft G is flattened so as to pass into a mortise in the front end of each drag-bar, and the two are connected together by a pivotal bolt, upon which the drag-bars rise and fall.
- the bars G turn in the tubes F, and are secured therein by placing on their upper ends the arms or bars 0, which are held down by a screw-nut or key at the end, the .bar 0 forming a shoulder to rest upon the upper end of the tube F.
- the tubes F are secured to the frame 0 by brackets a, bolted to the under side, as shown.
- the arms or bars 0 project back of the atchine used as a walking-cultivator.
- each drag-bar d has a separate and independent movement, and by tightening it they are made to move together in any position to which they may be adjusted, as they can be set nearly together or farther apart by'means of the rod t and set-screw s.
- the drag-bars D are moved to the right or left by the operator placing his feet on the foot-rests J, when the seat is high, or upon the foot-rests K when the seat is low. If desired, handles may be applied to the drag-bars, and the ma- By adding the bar ⁇ ?
- bent bar 10 in combination with the drag-bar D, shaft G, cylinder F, bar 0, and cross-rod t, substantially as and for the purposes specified.
