IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 84,935, dated December 15, 1868; reissue No. 4,939, dated June.

To all whom it may concern:

Be it known that I, J OSEPH H. BRINTON, of Thornbury township, Chester county, Pennsylvania, have invented a new and Improved Cultivator; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying sheets of drawing, and to the letters of reference marked thereon.

The object of this invention is to simplify the management of cultivators, and increase their efficiency, which is efl'ected by adapting the principle of steerage for governing the plows working adjacent to or straddling a hoed crop, for the purpose of keeping them at regulated distances from the row, thereby correcting any irregularity in the movement of the horses; also to provide the plow-beams with a plow, the shank of which is attached to the lower part of the plow-beam by a bolt, upon which the plow can swing, a break-pin being passed through the shank of the plowshare and the beam above the bolt, so securing the plow in a temporary position, that upon the share coming in contact with any obstruction of such power of resistance as may injure the device, the break-pin will give way and allow the plow to swing upon the bolt. The person operating has the power of guiding the said plows with his feet with the greatest nicety. While thoroughly cultivating the soil and tearing up the weeds he can prevent the slightest injury being done to the crop, the steerage being independent of the horses, and

' so simple that any one may control it with the greatest case. It is also eifected by the management of the plows of the same cultivator which work between the rows for cultivating the soil, removing weeds, 8:0.

The attendant, by means of double levers, which connect with atransverse adj usting-bar, moving in inclined slots or openings at the sides of the implement, is enabled to regulate the depth the plows enter the soil, or put a temporary pressure on them when they meet with obstructions from the hardness of the ground. V

The levers or arms to which the plows are attached, are, in a measure, self-regulating,

to press the plow of each into the soil.

On reference to the accompanying sheets of drawing, making part of this specification, Figure l is a plan view. Fig.2 shows the method of hinging the levers or arms carrying the plows to the front of the implement. Fig. 3 is a side view of the implement, showing the inclined slots, the transverse adjusting-bar, and the spiral spring on one of the plow-levers. The side-bar of the framing and the wheel on that side are, in part, sectioned, to show the arrangement of the aforesaid parts. Fig. 4 is 'a plan view of the steering-apparatus; Fig. 5 is a front view of the same. Fig. 6 is a front view of the plow 0. Fig. 7 is a side view of same, attached to plow-beam g by the bolt 11 and break-pin W. Fig. Sis atop view of same, showing hollow shank X. Fig. 9 is a side view of plow-beam 9; Fig. 10, same, with plow G attached; Fig. 11, same, showing line of movement of 0.

Similar letters refer to similar parts in the several views.

A is the frame of the cultivator, mounted on a suitable pair of wheels, B; a a, &c., are levers or arm s, each of which swings by an independent hinge-joint from the front bar b of the framing, and to which are attached the plows o 0, &c. C is an adjusting-bar, placed transversely of the implement, on which the levers a are carried. Its ends take into and move in the inclines D, fixed to the bottom at each side of the framing. E E are lever-handles, on both sides of the drivers seat F, two-being shown in this instance, though one can be made to answer the end sought. They have a vertical vibrating motion in the jaws d of theframin g. They connect by means of the rods 0 c with the transverse bar 0. It will be readily seen that as the handles are moved forward, the bar 0 is moved down the inclinesD, by which the plow-levers are gradually lowered, and a greater working depth given to the plows c. When the handles are moved in the opposite direction the bar 0 is moved up the inclines, which raises the plow-levers or arms a, lifting the plows 0 either clear of the soil or adjusting their working depth. The levers or arms a are, in a measure, self-regulating. Each vibrates on an independent hinge, being capable of working on irregular land, and able to adjust itself to any irregularities without disturbing the rest of the machine. Each lever is provided with a spiral spring, G, which is retained in its relative position by means of a yoke, f, fixed vertically to the transverse bar 0. The levers g g, which carrythe independent plows working adjacent to the rows of corn, are guided by the feet of the driver, on the steerage principle, to correct any irregularity in the movement of the horses, as follows: E is a lever, formed in an arc of a circle, and vibrates or rocks horizontally on a pin, h, in the front bar of the framing. iis a projection of the said lever, to which are fixed the ends of the chains or cords k k, which pass over the pulleys I, turning on the pins 1 l of the framing. The other ends'of the said chains arefixed to the levers g g, which, at this point, are placed sideby side, formingan eye,m, shown in dotted lines, Fig. 1, which takes over a pin, a, of the pole K of the machine. 0 is .a plow, which consists of the share z, which may be of any desired shape, and the shank w; in the present instance the share 2 and shank a: form one piece, the latter part being a tongue or continuation of the former. The shank w is open above and to the rear, its interior being of such dimensions as that it fits smoothly upon the front and sides of the lower end of the plow-beam g, to which it is attached by means of a bolt, 1;, or in any other suitable manner, so that the plow can swing upon the bolt 1) as a pivot. The plow -beam which may be curved or straight, is provided, at a proper distance above the aperture through which the bolt 4: passes, with an aperture, which is placed in the plow-beam, so that the distance between the upper and lower apertures in the beam corresponds with the distance between the upper and lower apertures in the shank of the plow. Through the upper apertures in the shank of the plow and the aperture 3 in the plow-beam is passed the break-pin w, of proper size and strength; thus the plow is secured in position.

The plow being arranged and provided as aforesaid, it is obvious that when in operating the device the share of the plow comes in contact with any substance of such weight or power of resistance as to threaten an injury to the machine, that the plow, acting as a'lever, of which the bolt 0 is the fulcrum, will break the pin w,which allows the plow to swing, and thus clear the obstruction.

The levers are parallel for a short distance, and then diverge sufficiently to enable the plows to work on both sides of the row. The ends of the are are provided with steps 0 for the feet of the driver. It will be seen, as the driver presses with his feet, alternately, on the steps 0, a horizontal motion will be given to the lever H on the pin k, that couples it to the front bar of the framing, which motion is imparted to the plows on the levers or arms g 9 adjacent to the rows, by the mechanism here inbefore shown, and enables the driver to cultivate close to the row without the slightest injury.

I wish it distinctly understood that I do not confine myself to the slot 1), as shown in the accompanying drawing, knowing it to be in the province of any skilled mechanic to devise an incline of diiferent construction, and accomplish the end sought. I do not confine myself to the mechanism herein shown for pre serving the relative position of the plows on the vibrating levers or arms 9 adj acentto the rows, being the steerage. I do not confine myselfto the spiral spring G, as shown, forkeeping the plows in the soil, and permitting them to yield to obstacles. I do not claim a U shaped shank, per 80,- nor do I claim, broadly, pivoting a shovel to a plowfbeam; but

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

1. A transverse adjustingbar, movingin inclined slots, or their equivalents, for the pur pose shown.

2. A yielding pressure applied to the arms or levers a, together with a transverse bar, moving in inclines, whereby to regulate the depth the plows enter the soil, and to ac-' vided with the break-pin w, as shown and described.

6. The hollow or U-shaped shank .r, pii'oted to the plow-beam g, and provided with the break-pin w, as shown and described.

7. The plow 0, consisting of the share 2 and hollow or U-shaped shank 00, provided with the break-pin w, and pivoted to the plow-beam g, substantially as shown and described.

In testimony whereof I hereunto sign my name to this specification in the presence of two subscribing witnesses.
