FLORAMAN '1. CHURCHILL, OF EAST PEAOHAM, VERMONT.

ZPLOW.

Specification of Letters Patent.

Patented Apr. 13, 1915..

Application filed February 7, 1914.. Serial No. 817,225.

To all whom it may concern Be it known that I, F LORAMAN T. CHURCHILL, a citizen of the United States, residing at East Peacham, in the county of Caledonia and State of Vermont, have invented new and useful Improvements in Flows, of which the following is a speci-' produce a frame structure including an axle and plow carrying beams laterally adjustable of said axle and right and left hand plows associated with the beams.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

lln the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,Figure 1 is a top plan view of a riding plow constructed in accordance with the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal vertical sectional view taken on the line 3-3 in Fig. 1. Fig. 4 is a rear elevation. Fig. 5 is a plan view of one of the beams, the plow carrying standard having been removed. Fig. 6 is a perspective detail view of one of the plows and standards. Fig. 7 is a detail bottom plan view of the rear ends of the beams and adjacent parts including the seat with dotted lines showing a different adjustment of the beams with respect to each other.

Corresponding parts in the several figures are denoted by like characters of reference.

The axle 15 of the improved riding plow is mounted on ground wheels 16, and said axle is provided in the rear part thereof with guideways 17 wherein slides 18 are guided, said slides carrying the forwardly extending beams 19 which rest and are supported on top of the axle, said beams being each provided with a fastening member such as a set screw 20 which by engagement with the upper face of the axle will serve to retain the beams at various adjustments, laterally, with respect to each other.

Each beam is provided with a T-shaped notch or slot 21 wherein is guided a standard 22 having laterally extending flanges 23, 24 that engage the head portion of the slot 21. It is to be noted that while the flange 23 that extends adjacent to the outer face of each standard may be of a length equal to the height of the standard, the inwardly extending flange 24L is interrupted about midway of the height of the standard, said flange being formed only at the upper end portion of the standard; this is in order that the flange may not interfere with the progress of the plow. Each standard carries a plow, said plows being respectively of the right and left hand types, the plows being so constructed and mounted that the lower ends of the respective standards will constitute the landsides of the plows; hence the necessity for omitting the inwardly extending flanges at the lower ends of the standards. Each plow is provided with an upwardly extending knife or cutter to assist in cutting the sod.

A foot lever 25 is fulcrumed on each beam, the forwardly extending arms of said foot levers being forced by actuating springs 26 outwardly in the direction of the stand ards. The latter are provided with vertically disposed series of transverse perforations 27 adapted to be engaged by tongues 28 which are pivotally connected with the front ends of the levers. The plow carrying standards may thus be securely retained at various vertical adjustments. Each beam carries a lever stand 29 on which is fulcrumed a hand lever 30, the forward end of which has a pin 31 playing in a slot 82 near the upper end of one of the plow carrying standards; it will be evident that when either foot lever is moved against the tension of its actuating spring to disengage the tongue 28 from the recesses 27 of the plow carrying standard, the latter may be adjusted vertically by the lever 80. The lever stands may each include a ratchet segment 33 with which the lever may be placed in engagement for the purpose of holding it at various adjustments.

7 Connected pivotally with each beam 19 at the rear end thereof is a seat support 34, and a seat 35 is pivotally connected with the upper ends of said supports. It follows that when the beams are adjusted laterally, this may be donewithout affecting the position of the seat.

The forward ends of the beams 19 are connected adjustably with a cross bar 36 by bolts or similar fastening means 37 for the passage of which slots 38 may be provided either in the beams or in the cross bar or in both. A tongue 39 which is connected with the cross bar 36 has a rearwardly extending fork a0 between the prongs of which a wheel .tlis supported for rotation, said wheel engaging the ground to support the forward end of the machine.

The operation and advantages of this device will be readily apparent to those skilled in the art to which it appertains from the foregoing description taken in connection with the drawings. Plow carrying standards may be readily adjusted independently of each other, thus permitting one plow to be supported above the ground, while the other plow is in operation. At the end of the row the last mentioned plow may be lifted while the machine is being turned, after which the other plow is lowered to ground engaging position. The plow carrying beams may readily be adjusted laterally when desired without interfering with the seat, and the operator, when seated, will be in a position to readily control the foot levers as well as the hand levers whereby adjustment of the plows is effected.

Having thus described the invention, what is claimed as new, is

1. In a device of the class described, an axle having guideways, slides movable laterally therein lengthwise of the axle, and plow carrying beams associated with the slides.

2. In a device of the class described, a wheel carrying axle having longitudinal guideways, slides adjustable in said ways, forwardly extending beams connected with the slides and supported on top of the axle, said beams being provided with slots, and plow carrying standards guided for vertical adjustment in said slots.

3. In a device of the class described, a wheel carrying axle, a forwardly extending beam connected therewith and having a T- slot, and a plow carrying standard guided in said slot and having laterally extending flanges engaging the wide portion thereof, one of said flanges being interrupted at the lower end of the standard, the latter constituting the landside of the plow.

In testimony whereof I aiiix my signature in presence of two witnesses.

FLORAMAN T. CHURCHILL.
