UNITED STATES PATENT OFFICE.

FRANCIS STANLEY, OF TORONTO, ONTARIO, CANADA.

PLOW.

SPECIFICATION forming' part of Letters Patent No. 225,769, dated March 23, 1880.

Application filed October 17, 1879.

T0 all whom t may concern:

Be it known that I, FRANCIS STANLEY, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, decorator, have invented certain new and useful Improvements in Plows, of which the following is a speci iication The principal object of the invention is t0 construct a gan g-plow so that the depth of the furrows may be easily and quickly altered, and, when necessary, the plowshares raised clear otl the ground, without detaching any part of the machine.

The machine is composed of two or more `plowshares pivoted to the main frame and connected to a lever so arranged that the driver can raise and lower the points of the plowshares without moving from his seat. The front of the frame is supported by a pair of wheels attached in the ordinary manner, and a smaller wheel held on an adjustable spindle is placed at or near the center longitudinally of the frame, and all the other details are arranged with the view ot' carrying out the object of the invention, as hereinafter more particularly described.

Figure 1 is a side elevation ot' machine. Fig. 2 is a plan of machine; Fig. 3, the other side of machine; Fig. 4, detail of cultivatingwheel and spindle.

In the drawings, A is the frame, of such suitable length and width as the number and size of the plowshares to be attached may require. B are the plowshares, provided with arms O, through which the pivot-bolts D, used for securing them to the frame A, pass. E are the colter bars secured to the plowshares B as shown, and passing through the guide-bars E', forming lateral stays for the plowshares. F are the colters, and Gr the plow-points, both ot' which may, of course, be ot' any suitable de sign. H are the front wheels, and I the auxiliary or adjusting wheel. J is the spindle ot' thevadjusting-wheel I. This spindle passes through the steadying-plates K, L, and M, and is provided with an adjusting-nut, N, situated. between L and M, aii'ording easy means of regulating the distance ofthe wheel Ifrom the frame A, and consequently the relative position ofthe plowshares B.

The lever O is pivoted to the pillar P, and is connected to the piowshares B by the links Q. This lever projects to the seat R, where a suitable catch, a, is provided for holding that end of the lever down, for the purpose hereinafter described.

Should I desire to use the plow as a light cultivator, I remove the wheel I and insert the cultivating-wheel S inits place, at `the same time turning the nut N so as to lengthen the spindle J, which movement has the ei'ect of raising the plowshares B clear of the ground, and the barbed wheel S, revolving as the ma' chine moves forward, acts very satisfactorily as a light cultivator, the barbs b, inserted, as shown, in the periphery7 of the wheel S, being specially adapted for the work they perform.

Having now described the general construction ot' the machine, I need scarcely refer to its advantages, as it" will be clear to any one familiar with this cla-ss of agricultural implements that the facility with which the depth ot' the furrow can be altered, the ready appliance for raising the plowshares clear of the ground, and the ease with which it can be converted into a light cuitivator will commend the machine to all farmers.

I have not referred to the material used in the machine or the dimensions of the various parts, as this class ofimplements is well known to manufacturers.

It will also be understood that the main frame A can be considerably increased in width and length to receive any desired number of plowshares B and adjusting-spindle J, with attachments.

It will also be evident that the mechanism for adjusting the spindle J might be other than that shown without affecting the principle ot' the invention.

What I claim as my invention is- The plowshare B, pivoted on the bolt D to` the frame A, the colter F, and colter-bar E, attached to the plowshare B, and working in the guidebars E', in combination with the links Q and lever O, pivoted to the pillar P, the whole arranged substantially as and for the purpose specified.

11i FRANCIS XS STANLEY.
