SPECIFICATION forming part of Letters Patent No. 420,587, dated February 4, 1890.

' Application filed April 5, 1886- serial No. 197,853. (to model.)

To all whom it may concern:

- Be it known that I, Lnwrs 13. WHITE, a citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of this specification.

This invention relates to plows; and it consists in the novel features hereinafter more fully set forth and claimed, and shown in the annexed drawings, in which- Figure 1 is a side view of a plow of my construction provided with my improvements and applied to a beam, a portion of which is shown; Fig. 2, a front view of the standard divested of its detachable parts; Fig. 3, a side view with parts removed and partly in section; Fig. 4, a reverse side view with parts removed. Fig. 5 shows the top edge and the rear or under side of the share. Fig. 6 shows a front perspective and planv view of the sweep-stock. Fig. 7 is a rear or-under side view of the sweep-stock on a reduced scale; Fig. 8, aside edge view of one of the sweeps; Fig. 9, an enlarged perspective detail of the supplemental beam-seat to be interposed between the beam and beam-seat on the standard; Fig. 10, a plan view showing portions of the beam and standard and adjusting wedge or block. Fig. 1-1.shows an end and a side view of the wedge or block interposed between the beam and the'side bearing of the standard. Figs: 12 and 14. are plan views or modified forms of the beam'seat on the standard. The position of the supplementalbeamseat is shown in dotted lines. Figs. 13 and 15 are plan and end views, respectively, of a modified form of the supplemental beam-seat to be inserted between the beam and the beam-seat on the standard. Fig; 16 is a bottom plan view of a modified form of a supplemental beam-seat to be used in connection with the form of beam-seat shown in Fig. 1 1. Fig. 17 is a rear View, on a reduced scale, of a beam and the upper portion of a standard,

showing the application of the supplemental beam-seat shown in Fig. 16, in which the said supplemental seat is provided with two flanges to embrace the opposite sides of the beam; and Fig. 18 is a detail view showing the flange of the wedge overlapping the upper curved end'of the vertical bearing.

The standard B is provided with two bearings, one of which is a vertical extension of a portion thereof up alongside the beam, and the other is a lateral extension or flattening of a portion of the standard under the beam. For convenience of referenceI shall hereinafter designate these bearingsas the ver- ,is curved, as shown, so that the beam will readily tilt thereon as its draft end is raised or lowered. The upper edge 19 of the vertical bearin b is curved as shown and is arran ed preferably flush with the upper surface of the beam; but it may be in a diiferent plane, as will be hereinafter explained. l

A wedge or block C, provided with a flange which overlaps the beam, is pivotally held on the bearing 19 so that it will turn with the beam as the latter is adjusted, but it does not lift vertically. This wedge or block is placed at the pivotal center of the beam, and the flange or lip rests in its entire length on said beam in all the various adjustments of the latter, and thus affords a brace or support for the pivotal bolt, and as it moves with the movement of the beam the latter is not injured by being out into, as would be done by a flange integral with the standard which would bear only on a small portion of its surface when the beam is adjusted vertically. The wedge or block is preferably interposed between the vertical bearing and the beam; but it may be made L-shaped and placed on the outside of the bearing, and the flange will then extend over the top of the said bearing and onto the top of the beam. I prefer to interpose the pivotal block between the verticalbearin g and beam, as shown, and to make it wedge-shaped, for thereby I secure additional advantages, as willbe made clear hereinafter.

The wedge or block is provided with a longitudinal slot to permit its longitudinal adjustment on the retaining-bolt a. It is provided with a gudgeon or side lug C arranged and adapted to enter a recess or bearing 1) in the side of the bearing If. The slot is made wider than the bolt, so that the edges of said slot may not come in contact with the bolt during the vertical adjustment of the draft end of the beam, and thereby bind the wedge and lift its flange from its bearing or seat on the upper end of the vertical bearing or beam. There may be a series of holes I), which will permit the longitudinaladjustment of the block; or, instead of a series of holes, an elongated recess may be provided, as shown in dotted lines. If the block 0, instead of being wedge-shaped, were of rectangular form, to be used simply to set the beam bodily out fronrthe bearing without changing the line of draft, there would be no need of but a single hole I)". The block would support the beam and bolt by its overlapping flange and lug, and at the same time its opposite flange would rest on the curved upper edge I) in any vertical adjustment that might be given to the end of the beam. I prefer to make the bearing 12 with the series of holes or the elongated recess, so as to provide for the longitudinal adjustment of the wedge or block.

\Vhile I have shown the lug on the block and the recesses in the standard-arm, yet it will be clearly understood that the lug may be on the standard-arm and the recess or recesses in the wedge or block.

The wedge or block 0 has projected the side flanges C 0 preferably in the same plane, which give it a cross or T head, which overlap the beam or vertical bearing, as shown. If the upper edge of the vertical bearing were not flush with the upper surface of the beam, then the flanges C 0 would be arranged in different planes to adapt them to the different relative positions of the bearing and the upper surface of the beam.

It will be understood that in giving a vertical adjustment to raise or lower the draft end of the beam the wedge or block has a tilting but no vertical, movement on the vertical bearing, while its relation to the beam is unchanged.

The Wedge or block is fixed as regards any vertical movement independent of the beam; consequently it rocks in unison therewith as the latter turns pivotally about the bolt ct.

' The flange C rocks over the curved end I),

while the entire length of the flange C rests on the beam, which length of bearing remains unchanged, and the beam is thereby prevented from being cut or worn, as hereinbefore explained. It will be readily understood that the wedge may be made with a single flange to overlap the beam, or to overlap the standard, or both, as may be desired.

The beam-seat b is preferably inclined on its upper surface, forming an acute angle with the under side of the beam, and the intervening space is filled by an adjustable supplemental beam-seat D. The adjacent faces of the supplemental seat and beam-seat are preferably provided with interlocking teeth or other means to prevent possibility of slipping. The teeth may be dispensed with and the fastening-bolt be made to hold the parts together. A flange D, projected from the supplemental seat D, is or may be longitudinally slotted in a direction parallel with the face which lies against the beam. A flange may also be formed on the opposite side.

A slot d is formed in the supplemental seat parallel with the length of the beam or line of draft. \Vhen this seat is placed on the beam-seat b, the slots 11 and d are at right angles to and cross each other, and the fastening-bolt a passes through both of them. The bolt is fixed in its relation to the beam.

The supplemental seat shown in Figs. 1 and 9 has a longitudinal adjustment relative to the beam, whereas, with reference to the standard, it has both a longitudinal and transverse adjustment.

In Figs. 16 and 17 the supplemental seat is shown as provided with a flange extending part way on each side of the beam, and in Fig. 16 pointed lugs or teeth (1 are shown on each side of the slot (1' for engaging corresponding indentations d, a series of which are provided 011 the top beam-seat, (shown in Fig. 14,) so that the teeth (1 may engage some one thereof when the supplemental seat is adjusted. It is manifest that the teeth may be formed on the standard and the indentations on the adjustable seat.

Figs. 12 and 13 show a modification in which the supplemental seat has a transverse adjustment relative to the standard by means of the threaded arms D projecting laterally from each side thereof to receive adjustingnuts, which are adapted tobear on the sides of the cross-bearing. The lateral movement of the seat with referenceito the standard is effected by loosening one nut and tightening up on the other. By this arrangement a much nicer adjustment can be made than by any other means. The nuts could be left off,

if desired, in which case the arms D will assist in holding the support in place and give firmness to its position. The arms project beyond the plane of the support and are adapted to be seated in one of a series of transverse grooves 11 in the upper side of the beam-seat, thereby performing the oflice tral line or apex B having projections on the rear to fit into cor of interlocking teeth,"and insuring a stable and firm connection between the parts after? responding notches or recesses 6 near the upper outer corners of the wings, are removably secured thereto in any well-known manner.

The lower portion of one of the wings has a.

notch e in its edge. In the other winga re-.

cess or socket e is formed, which extends from itsedge across its face and terminates in the opposite wing at a point beyond the central line B The double point or share F is adapted to fit snugly against the lower edge of the moldboards when properly seated and secured to the lower portion of the expanded end. The socket or recess F in the rear or underside of the share receives and forms a seat for the end of the standard. A projection f, extending within the socket, coincides with the notch e in the wing to steady the point and prevent lateral displacement thereof. A second projectionf', springing from the opposite side of the socket and extending across the angle of the wings and connecting with the opposite wing, strengthening and forming a brace for both wings, while at the same time fitting in the socket e in the lower portion of the standard, affords a means for securing the pointor share in place, the projection being recessed, as shown at f, for the reception of a bolt-head for securing such castings to a standard, as shownin my previous patents. v

A further object in locating the fastening for bolt-head as described, so that it extends to both wings of 'share,'is.to have it at the middle, so that the bolt-head will draw on both wings, thus dividing the strain and there: by reducing to the minimum the liability to break. i

To the bar B of the standard is adjustably secured asole-piece G by a bolt g, passing vertically, and a bolt g passing transversely, through.,' The upper side of the bar is concave or curved on the arc of a circle, and

' the direction of the channel-h, allows the bolt g toproject through and adj ustably secure the holder in. position; The faces of the wings are formed approximately on the segment of a sphere, and the rear side of the inner end of the sweeps I are made of corresponding shape to fit snuglythereto and pre sent aball-and-socket joint, so that the sweep may be adjusted in the arc of a circle from end to end, vertically and laterally, to regulate the throw of the earth to the plants and to increase or diminish the track or path according to the distance of the rows, respectively. The best results are obtained by convexing the ends of I.

the sweeps, although it is evident that this order may be' reversed with equal results, solong as an approximately ball-and-socket joint is maintained between the two parts.

The inner end of the sweep has a slot 2', and the wings of the holder have slots 71 said slots in sweep or holder being arranged transversely to each other, a bolt 2", passing laterally through the slots in each sweep and wings of the holder, binding the two together. By loosening the bolt the shank of the sweep may be adjusted to give a greater number of inclinations or-sets to the sweep than can be done by any of the ordinary means of adjustment. It may be adjusted so as to give, its face any desired pitch without changing its horizontal position; or it may be turned either up or down about the bolt as an axis to regulate the inclination of the sweep to the ground, its angle with the standard, and its pitch, respectively, as occasion may require.

To render more positive the binding action of the bolt and to guard against accidental displacement of the sweeps when adjusted by neglecting to properly tighten the bolts, one or more teeth i are formed on that side of the sweep ad'jacent, to engage one or more of a series of indentations or depressions 72. in said holder.

If it is desired to raise or lower the sweeps without changing their set relative to their position on the holder, the bolt g, securingthe holder in place, is slackened and the sweepholder left free to be adjusted on the bar, and by reason of the concavity of its upper surface the holder may be adjusted to a higher or l0wer level, as required, carrying therewith the sweeps. By tightening the bolt the holder is secured in its adjusted position. Interlocking teeth h are provided between the contacting surfaces to render more positive their binding action.

It will be noticed that the entire beam may be adjusted laterally on both bearings of the standard, but that it is vertically adjustable on only one of said bearings. The bolt a, connecting it with the standard, forms a fulcrum or axis about which the beam tilts when its draft end is adjusted vertically.

Instead of having'a holder projected laterally from the standard, as particularly shown, I can form on or in the side of the standard a projection or recess, which will be the segment of a sphere, and correspondingly form the inner end or shank of the sweep, so that the two parts fit together as a ball and socket. Then by providing these adjacent parts with suitable slots I secure allthe movements set forth for the sweep when attached to the proj ected arm of the sweep-holder.
