-of the invention, such as will enable others skilled it the art to which it appertains to make l and use the same.

A being also This invention relates jointersfor plows.

The object of the invention is to provide a jointer for plows which will eiiciently cut its way through all kinds of weeds and trash, thereby preventing the same from clogging the plow. v kA further object is to provide means for attaching the jointer to the plow-beam to permit said jointer to be adjusted laterally, means provided for raising and lowering the jointer.

AWith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

V In the accompanying drawings, Figure 1 is a side view of a portion of a plow-beam, showing thev jointer applied thereto. Fig. 2 is a front elevation of the same, partly in section. Fig. 3 is a vertical cross-sectional view through the beam and the rear end of the upper attaching-plate, showing the clamping device for to improvements in securing the rear end of the same to the beam.

Fig. 4 is a top plan view of the upper attaching-plate. Fig. 5 is a similar view of the lower attaching-plate. Fig. 6 is a vertical sectional view through the jointer and its attachingbracket, and Fig. 7 is a similar view taken at right angles to Fig. 6.

Referring more particularly to the drawings, 1 denotes the plow-beam, on the under side of which is secured an upper attachingplate 2. Said plate is provided near its forward end with slots 3, said slots being arranged on opposite sides of the center of the plate, as shown. Through the slots 3 are in- Serted upwardly-projecting bolts 4, which are adapted to project on each side of the plowbeam, the upper ends of the bolts passing through a clamping-bar 5, which engages the upper side of the plow-beam. On the upper ends of the bolts 4 are adapted to be screwed nuts. 6, whereby the front end of the attaching-plate 2 is rmly clamped to the plow-beam. The rear end of the plate 2 is recessed or cut away, as at 7, and in said cut-away or recessed portion is slidably mounted a pair of clampingbars 8, said bars being provided with alined longitudinally disposed slots, through which is passed a securing-bolt 7', which also passes through an aperture 8 in the end of the plate 2. The outer ends of the clamping-bars 9 are provided with upwardlyprojecting lugs 10, which are roughened on their inner sides and are adapted to engage the opposite sides of the plow-beam. When the lugs 10 have been firmly engaged with the sides of the plow-beam, the nut on the bolt 9 is tightened, thereby holding said clampingbars into tight engagement with the beam, and thus securing the rear end of the plate 2 to the beam. The front end of the plate 2 is provided with a downwardly-projecting rightangularly-formed extension 13, in which is Y formed a transverse horizontally-disposed slot 14.

On the lower side of the plate 2 is secured a lower attaching-plate 15, said plate being provided near its rear end with a transverselydisposed slot 16, through which and a centrally-disposed aperture 17, formed in the plate 2, is inserted a bolt 18. On the lower end of the bolt 18 is screwed a nut 19, thereby adjustably securing this end of the plate Y k 15 to the upper attaching-plate 2. On the forwardV end of the lower plate 15 is formed a downwardly-projecting right-angularly disposed projection 20, in which is formed a centrally-disposed aperture 21. Through this aperture 21 and through the slot 14 in the eX- tension 13 of the upper plate is passed a bolt 22, on the outer end of which is screwed a nut, whereby the forward end of the lower plate is adjustably secured to theupper plate. On the under side of the plate 15 is formed a downwardly-projecting obliquely-disposed arm 23, in one side of which is formed a longitudinally-disposed channel 24. The arm 23 is also provided with a longitudinally-disposed slot 25. In the channel 24 of the arm 23 is adjustably secured the upper end of a jointer-standard 26, said standard being provided near its upper end with a bolt-hole, through which and the slot 25 of the arm 23 is arranged a bolt 27. Said bolt is provided on its end with a nut 28, which when screwed up into engagement with the side of the arm 23 will securely hold the standard 26 in any of its adjusted positions on the arm 23, thus IOO IIO

p permitting the jointer to be raised or lowered,

as desired. On the lower end of the standard 26 is formed an enlargement 28, said enlargement being provided with a verticallydisposed aperture 29, the lower side of the enlargement 28 being provided with a roughened or serrated surface.

Adapted to be engaged with and secured to the enlargement 28 of the standard 26 is a bearing-bracket 30, said bracket being provided with a right-angularly formed arm, the upper side of which is provided with a roughened surface which is adapted to engage the roughened surface of the enlargement 28. The right-angularly-formed arm of the bracket 30 is also provided with a vertically-disposed aperture 31, which is adapted to aline with the aperture 29 in the enlargement 28, and through said alined apertures is passed a securing-bolt 32, on the lower end of which is adapted to be screwed a nut 33, which when screwed upon the bolt 32 will securely clamp the bracket 30 to the enlargement 28. In the vertical arm of the bracket 30 is formed a transverselydisposed aperture 33', in which is adapted to be inserted a bearing-box 34. In the box 34 is mounted a short shaft or spindle 35, between which and the box 34 is disposed a bushing 36. On the shaft or spindle 35, adjacent to the outer end of the same, is rigidly secured a circular plate 37, to which is bolted or otherwise secured a disk jointer 38. Said disk is provided with a centrally-disposed aperture 39 to iit over the end of the shaft or spindle, the outer end of said shaft or spindle being provided with screw-threads, on which is adapted to be screwed a nut 40, by which the disk jointer is rigidly held on the spindle 35. The disk jointer is here shown as secured to the plate 37 by means of screw-bolts 41, which are countersunk in the disk 38. On the opposite end of the spindle 35 is screwed a securing-nut 42, whereby the shaft or spindle 35 is secured in the bracket. rlhe box 34 is secured in the aperture 33 of the bearingbracket by means of a set-screw 43.

A jointer constructed and arranged as herein shown and described may be adjusted laterally on the plow-beam and may be also lengthened or shortened, the construction of the parts also being' such as to permit the jointer to be arranged on either side ofthe standard, as will be understood. j

While the device is shown as being connected with a wooden-beam plow, it is obvious that the same may be connected or applied to a steel or iron beam without materially chang'- ing the construction of any of the parts.

From the foregoing` description, taken in connection with the accompanying drawings, the construction and operation of the invention will bc readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention. a A
