T a/ZZ whom t may concern,.-

Beit known that I, J AMES MOORE, manager T. Robinson & Co. ProprietaryLimited, a subject of the King of Great Britain and Ireland, residing at Braeside, Railway Crescent, Elsternwick, in the British State of Victoria, Commonwealth of Australia, have invented certain new and `useful Improvements in Disk Plows, of which the following is a specification. i

This invention relates to improvements in disk plows; and it consists mainly in an improved framework therefor which, in addi- .tion to its adaptability for quickly altering the width of the furrows, always preserves and correctly maintains at any desired width of said furrows the proper line of draft, the improvements being equally applicable either to a two-furrow low or to a plow for cutting a greater num er of furrows, while the other improvements consist in the means of supporting and adjusting the disks and to other combinations of parts hereinafter de scribed.

The invention will now be fully described, aided by a reference to the accompanying sheet of drawings, in which-r Figure l is a perspective view of a disk plow embodying my improvements; Fig. 2, a plan view to clearly illustrate the adjustable framing which carries the disks; and Figs. 3 and 4 are side view and plan, respectively, of the front furrow-wheel bracket, while Figs. 5, 6, and 7 are side and end views and plan, respectively, of the adjustable bracket for supporting the disks. y

The framework comprises a system of parallel beams or bars, of which those marked A have their rear part bent at an angle of forty degrees, or thereabout, toward the disks B, which they support, while a shorter bar A supportsthe front furrow-wheel bracket or carrier C, and a longer beam A4 carries the .hindmost disk and the back furrowfwheel. The beams A and A are pivotally secured at their fore ends by bolts a to a bar A2, which lies obliquely over them, while at a short distance rearward and lying parallel with afore said oblique bar A2 are a pair of over-and-under oblique beams A3, the angle of said h oblique beams A2 and A3 being such as will allow for the forward advance of the line of disks B. Said disk beams A and A lie between and are pivotally secured by bolts a to the under and over oblique bars or beams A3.

The landside or rear disk beam A4 also lies parallel with beams A, and it also is pivotally connected by bolts a and a with the oblique beams A2 and A3, while the front part of beam A4 extends in a direct line forward to a position about transversely opposite to the end of the front-wheel beam A, and the for ward end of both said beams A and A4 are connected to atransverse bridle-bar A5, which stretches across the full width in front of plow-frame and has an extension a2 pro-4 ris attached. The object of the projection a2 on the furrow side is to enable the draftchain a3 to be hooked or shackled at a position well beyond the center line of draft in order to counteract against the landward tendency of the rear disks. Alsoby the bridlebar Av being of such an unusual length and at such va forward position the p low is caused to run or work steadily and with less tendency to lift the disks B from their working or cutting osition. The said bridle-bar A5 at both its ends has a series of holes a4 to secure the plow-frame at its desired width and also to receive the shackles a5. D is a screwed adjusting-rod secured by collars d to a bracket d, arranged on the landside-beam A4, while its screwed part takes into a swivel-nut d2, secured to the oblique beam A2, and D is a handle for rotating the screwed rod D and which latter is used for the purpose of adjusting the distance apart of the beams carrying the disks, and ,hence regulating the width of the furrows, and which adjustment in the width of furrows may be from a fraction of an inch to several inches.

By detaching the bridleebar from either or both bar A and beam A4 and then rotating screw-threaded rod D inthe proper direction the inclined or oblique beamsA2 A3 will be swung forwardly or rearwardly the desired distance to bring the plow-bars A the re quired distance apart, and consequently space the plows or disks B as desired. During this adjustment the inclined beams swing on their pivotal connections with beam A4 and also on the various bolts a a', and the plow-bars A are maintained parallel with IOO each other and in the line of draft. After the parts have been adjusted to bring the `glows B the desired distance apart the brile-bar is again attached to the front ends of bars A and beam A4. y

The vertical post of the rear furrow-wheel C2 is carried by a bracketwhih is secured to the landside-beam A, while the vertical post of the front' furrow-wheel (y is supported by the bracket C, attached to the off-side beam A/, and as said front and rear furrowwheel posts are connected by levers they will always maintain a true draft line.

. The bracket C, which supports the post of the vfront furrow-wheel C', is provided with side lugs c,in which are slot-holes c, through which bolts c2 pass for securing said bracket to the bar A ,and by said slots c lying transverse to the line of draft the front furrowwheel can be adjusted to a greater or less width of furrow when necessary. Said bracket is provided with an extension or foot piece c3, which rests onj'the front oblique beam A2 to maintain the vertical position of the front furrow-wheel post.

The whole of thesystem of framework-bars (marked A to A5, respectively) are usually placed on the flat and not edgewise, as is the ordinary practice in other plows. Further, the framework is `made preferably of springsteel,` the disks B being carried by cast-iron or other metal bearing-brackets E, in which the disk axles revolve, while said bracketbearings are secured to the rear end parts of the beams A and to the beam. A4. The said bearing-brackets E are so constructed that each may be adjusted to set the disks at the re uisite angle by Veach bracket-bearing being secured to the under side of the disk beams A and beam A4 by two bolts e and e, the forward bolt e passing through a hole in the beams and flange of lbearing-bracket E and the rear bolt e passing through a hole in the beam and through a radially-slotted hole e2 inthe bearing-bracket E. The flange E of the bearing-bracket E is rabbeted at e3 to permit of a stop-plate E2 being placed between the rear part of the bearing-flange E and the beams A or the beam A4, said plate E2 being serrated at c4 on its under side to receive an angular projecting rib e5, formed on the rabbeted part of the ange EQ so that when the bolts e and e are screwed up the bearing-bracket E will be locked securely at the desired position to suit the angle at which each disk B is to lie, the forward bolt e during the process of adjustment acting as a pivot.
