SU LKY-PLOW.

SPECFICATION forming part of Letters Patent No. 462,285, dated November 3, 1891.

Application filed February 4, 1891. Serial No. 380,129. (No model.)

.To aZZ whom it may concern:

Be it known that i, CALEB E. TOWER, a citt zen of the United States of America, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvementsin Sulky-Plows, of which the following is a specification.

My invention is an improvement in sulkyplows, and is designed especially to provide for the quick manipulation of the front and back furrow-wheels in unison, so as to make the plow capable of a quick turn either to the right or left andto provide such an arrangement as will permit the locking of either wheel against swiveling, while the other is permitted to swivel and thus guide the plow.

The invention includes details of construction relating to this feature of the plow and other parts which tend to improve the plow generally, all as hereinafter particularly de scribed.

The plow illustrated in the accompanying drawings is what is known as the Solid Comfort, manufactured by the Economist Plow Company, and in its general construction is well known, so that I have therefore not attempted to illustrate the sulky particularly, but only in the respects in which it has been improved by the details of construction which are the subject of the present invention.

The drawing represents a perspective view of the plow.

In the drawing, A represents the plow-beam, to which is rigidlysecured the plow, the beam being pivoted at its rear at the point c. The land-wheel (shown at 8) is provided with a lever 1 for operating it, so as to level the plow on hillsides and uneven ground. The front furrow-wheel 7 is secured to a spindle, which is bolted adjustably to an upright arm 13, having a swivel connection in a socket 15, which is bolted to the frame A of the plow. The rear furrow-wheel or revolving landside is the same in construction and operation as that shown in Letters Patent No. 442,671, dated December 16, 1800.` The bracket which sup` ports the wheel is provided with a verticallyarranged spindle fitted to a socket in an extension of the plow-beam, and the upper end is provided with a crank-arm 5. The upright arm 13 of the front furrow-wheel is provlded with a similar crank-arm e, and the arms et and 5 are connected through the operating-lever 3 and the rods 1l l2. Each of these rods is made in two pieces, which are connected by bolts and slotted openings, so that they may be easily adjusted to make them longer or shorter. The rod 11 extends from the arm 5 to the lever 3, and the rod l2 extends from the said lever to the crank-arm 4. A sector 16 is secured to the fralne of the plow, as is also the lever 3, and it will thus be seen that in the operation of the lever the front and rear furrow-wh eels are manipulated simultaneously to turn the plow in one directionor the other, and this movement is imparted without regard to the direction iu which the team is going, as the action is entirely independent of the team and under the control of the operator or driver.

The spindle of the front furrowwheel (shown at 14:) is provided with a series of openings, and the upper face of the spindle is preferably of angular shape adapted to a recess in the under part of the upright 13, and the two are secured together by bolt 19, passing through the foot of the upright and the spindle in rear of the wheel. In this way the front wheel may be adjusted in or out to aid in controlling` the widths of the furrow.

The lever 2 with its sector and plunger are substantially the same as are in use on the Solid-Comfort plow, but are differently located. In the present case the sector and lever are secured to the beam, and this lever serves to give the depth of the furrow. A casting 9, in the shape of a loop, is secured rigidly to the frame of the plow, and in this hooks a projection or foot 17, which forms a part of the lever 2. This loose foot engages with the slotted casting, and thus forms a bearing for the end of the lever, and as it is pivoted to the plow-beam the operation of the lever 2 will raise or lower the said beam. The foot 17 is not rigidly secured to the end of the lever2, but is connected thereto loosely, so as to have a certain amount of lost motion, thus preventing the fracture of the parts in case of a sudden shock.

In order that either of the furrow-wheels may be held rigid against swiveling in its support while the other is connected to and operated by the lever 3, the rods 11 and 12 are removably connected to the lever, and

IOO

when it is desired that either wheel be held rigid its rod is disconnected from the lever 3 and it is fastened by the same bolt to a stationary part on the frame-as, for instance, the lug B, formed with the sector l-or the rod may be removed entirely and the correspending wheel held byv a set-screw.

I claim as my invention- 1. In a sulky-plow, front and rear furrovsT wheels swiveled in their supports and having horizontal crank-arms extending in opposite directions, and means for moving the wheels simultaneously and independent of the movement of the tongue, consisting of t'he'rodsl ll l2, extending between the prank-arms, and an operating-lever arranged intermediate of the Wheels andthe adjacent ends of the rods, to which said rods are pivotally l'ixed, sub1 stantial'ly as described. n

2. In a sulky-plow, front and rear furrowwheels swi'veled in their supports and having horizontal crank-arms, the intermediate lever, and the rods ll and l2, extending therefrom on each sideand connected to the crank-arms, each of said rods being formed of overlapping pieces connected adj ustably by bolts passing through slots, substantially as described.

3. In combination with a pivoted plowbe'ar and with a rigid'fra'me of the sulky, a lever and sector connected to the plow-beam, said lever being provided with a loose foot, and a slotted casting adapted to engage with the end of the loose foot, said casting being secured' to the plow-frame, substantially as described.

4. In combination with the frame, the furrow-Wheel, the spindle therefor having at its rear portion a ribbed upper surface, a standard 13, having a foot adapted to fit said surface, and the holding-bolt, substantially as locking either of said wheels against swiveling when its rod is disconnected from th'elever 3; substantially as described.

In testimony whereof I affix my signature in presence of tWo witnesses.

CALEB E. TOWER'.
