SPECIFICATION forming part of Letters Patent No. 329,919, dated November 10, 1885.

Application filed July 10, 1885.

To all whom it may concern:

Be it known that I, JOHN M. W. LONG, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Gultivators, of which the following is a specification. I

This invention relates to tongueless straddle-row cultivators.

The invention will be readily understood IO from the following description, taken in con nection with the accompanying drawings, in which Figure 1 is a rear perspective view of acultivator, illustrating my improvements; Fig. 2,

1 a side view of the same with a portion of the right-hand Wheel broken away; Fig. 3, aplan of the right-hand plow, the standard B, which connects it with the arelrbar, being shown in horizontal section; and Fig. 4, an elevation of one of the stub-axles, showing one of the coupling-blocks in section.

In the drawings, A indicates the arch-bar, being a straight bar adapted to reach from plow to plow over the corn-row; B, standards reaching upward from the stub-axles and engaging the arch-bar; O,the stub-axles on which the wheels loosely revolve, and which are themselves loosely journaled in boxes at the foot of the standards; D, coupling-blocks located upon the axles upon the inner side of the standards; E, the plow-beams having the usual handles, plowshares, &c., and coupled to the blocks D by a vertical bolt; F, vertical spring-rods whose upper ends engage the archbar and whose lower ends pass transversely through the inside ends of the stub-aXles; G, clevis-bars pivoted to the box at the foot of the standards and to the coupling-blocks, which'latter have a forward projection to re- 0 ceive the pivot-bolt of the clevises; H, setscrews in the forward projection of each of the coupling-blocks, these set-screws being arranged vertically and underneath the clevis, which latter they serve to sustain and adjust;

5 J, shoe-bars lying alongside each plow-beam and having their upper ends pivoted thereto, the free ends of the shoe-bars being bent into runner form; K, frontwardly-opening notches in the shoe-bars, these notches serving to receive the shoe-bars when the same are turned Serial No. 171.951. (No model.)

downward; and L, dotted lines indicating the position of the beams and shoe-bars when the shoe-bars are in use. Each clevis is provided with a single-tree, to each of which a horse is to be hitched, each horse thus pulling independently upon his plow. The forward ends of the clevises may be adjusted in elevation or depression by means of the set-screws H, whereby the tendency of the draft in regulating the depth of cultivation may be adjusted. If the front ends of the clevises be set high, the tendency of the draft will be to pull them downward, and thus elevate the plowshares. The forward end of each plow-beam is attached to its appropriate stub-axle by means of a vertical bolt passing through jaws upon the ends of the plow-beam, through the couplingblock, and through the stub-axle. The beams may be oscillated horizontally upon these bolts, and in oscillating vertically the stubaxles rotate within the box at the foot of the standard and also within the wheel. Either plow-beam is at liberty to be swung to the right or to the left, this swinging motion taking place upon the coupling-bolt. Either plow may be raised or lowered at will, the springs F permitting this movement by their fiexation. The stub-axles are prevented from improper rotation by reason of the practically rigid adjustment in the coupling-blocks, the coupling-bolts passing through the blocks and axles. The springs are thus supported in an upright position by the non-rotary stub-axles, and the springs serve to sustain the arch in an upright position. If one plow be pulled in advance ofthe other, the standard of that plow pivots upon the arch-bar at the top and upon the stubaxle at the bottom, the motion being rendered elastic by the springs. One plow may be advanced and the other checked or pulled backward, and the arch-bar will still occupy its proper position. The shoe-bars J normally lie idle alongside the beams, their forward ends being supported by hooks. When the cultivator is to be moved from the field or along the road, the shoe-bars are allowed to drop. The plow-beams are then lifted a trifle by means of the handles, and as the cultivator advances the shoebars take the position indicated by the dotted lines in Fig.

2, in which thebeams will be so much elevated that the teeth or shares will be free of the ground, and the structure will drag upon the shoe-bars. The standards B, as usual, are adjustable along the arch-bar to suit different widths of work. The eyes of the upper ends of the springs slide along the arch-bar when such adjustment of the standards takes place. I claim as my invention 1. In a tongueless straddle-row cultivator, the combination of a pair of stub-axles,wheels thereon, beams with their forward ends coupled to the axles, standards having their lower ends journaled upon the stub-axles, and having their upper ends coupled to form an arch, and vertical spring-rods having their lower ends secured to the stub-axles and their upper ends secured to the top of the arch, substantially as and for the purpose set forth.

2. In a tongueless straddle-row cultivator, the combination of axles G, the wheels loose thereon, beams D, coupled thereto, the archbar A, the standards B, articulated to the axles and to the arch-bar, and the spring-rods F, connected to the axles and to the arch-bar, substantially as and for the purpose set forth.

3. In a cultivator, the combination of the stub-axles G, the arch connecting them and adapted to.oscillate upon them, the wheels.
