MOLDBOARD AND SHARE.

Specification of Letters Patent.

Patented Dec.. ai, 191 s.

Application led August 19, 1918. Serial No. 250,545.

To all whom. t may concern.'

Be it known that I, BERNT PAULsoN, a citizen of the United States, residing at Canton,y in the county of Lincoln and State of South Dakota, have invented new and useful Improvements in Moldboards and Shares, of which .the following is a specification.

This invention relates to mold boards and shares for plows and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide in combination with a share having at its upper edge portion recesses, .a mold board composed of a series of movable elevators or conveyers adapted to be encountered by the furrow slice as it moves in an upward direction from the share whereby the said slice may be readily turned inasmu-ch as friction incident to the turning operation is in a great measure eliminated.

With this object in view the mold board consists ofV a series of frames attached with the plate which supports the share and spaced from each other. The forward ends' of the framesy are located adjacent the recesses in the share. Articulated link belts are mounted for movement along the frames and the links of the belts are in close contact with each other and with the side por tions of the frames thereby forming closures for the frames. The frames may be filled with grease or other lubricant. Rollers are loosely journaledy in the frames and means are provided for lubricating their gudgeons. The links carry lugs which are adapted to move over the rollers and consequently friction is reduced at the end portions of the frames which receive the furrow slice in view of the fact that the links cannot be buckled or forced out of proper relation with respect to each other.

In the accompanying drawing:-

Figure 1 is a top plan view of the mold board and share.

Fig. 2 is a bottom plan of the same.

Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2.

Fig. 4 is a detailed view of one of the elevators, parts being broken away and in section.

Fig. 5 is a cross sectional view on the line 5-5 of Fig. l.

Fig. 6 is a cross sectional view on the line 6-6 of F ig. 4.

Fig. 7 `is a fragmentary side elevation of one of the elevator frame parts being broken away.

Fig. 8 is a fragmentary elevation of one of the elevator chains, showing the under side thereof.

Fig'. 9 is a sectional view taken on the line 9-9 of Fig. 4:.

Fig. 10 is a fragmentary side elevation of one of the elevator chains.

Fig. 11 is a longitudinal sectional view showing a fragment of one of the elevator chains. i

Fig. 12 is a perspective view of one link of the chain and,

Fig. 13 is a perspective view of the end of one side of one of the elevator frames.

As illustrated in the accompanying drawing theshare 1 is of usual pattern and is provided at its upper rear edge portion with recesses 2. The share 1 is mounted upon a supporting plate 3 in a usual manner.

Brackets 4 are connected at their forward ends with the plate 3 and a guard strip 5 is connected at its lower forward end with one end portion of the plate 3. The guard strip 5 is curved longitudinally and its upper end portion is disposed over the intermediate portion of the share 1.

Frames 6 are connected at their lower forward ends with the brackets 4 and the said frames are curved longitudinally. The frames 6 are disposed at acute angles with relation to a horizontal line. The frames 6 are spaced from each other and are approximately parallel with the guard strip 5.

Rollers 7 are journaled within the frames (3 throughout the entire lengths thereof between the side members thereof and the gudgeons `of the rollers pass through the side members of the frames. The side members of the frames 6 are provided at their outer surfaces with longitudinally disposed channels 8 and plates 9 are applied to the outer surfaces of the sides of the frames 6 and bridge the said channels. The plates 9 are provided at their upper ends with openings 10 which are norinallyy closed by plugs 11. By removing the plugs 11 a lubricant may be inserted in the channels 8 and this lubricant will gravitate down along the channels and lubricate the gudgeons of the rollers 7.

Packings 12 of rubber, felt or other suitable material are extended around the edges of the side membersoi:I the frames 6. Spa-1 ing ba-rs 13 are located between the side hold them at proper distances apart. The

side members of the frames 6 are provided A at their edges with inwardlyVV disposed` flanges 14 which are cut away as at 15 inv the vicinity of the upper ends of the side portions of the frames.

Link 'belts are mounted for movement around the frames 6. These belts are composed of articulated linksl 16 which it snugly and closely against each other and the links are provided at their opposite edgesw-ith p-ackings 17 which are adapted to prevent the grease from passing between the links. The links are in close' Contact with the edges of the side'members of the frames 6 and the packings l2 consequently the links collectively serve as closures for the frames inasmuch as they bridge the spaces between the side members of. the frames. By disconnecting the links from each other a lubricant as for instance grease may be inserted between the side.- members .v of the frames through the cutaway portions 15 of the flanges 14. Some of the linksV 16 are provided at their inner sides withV lugs 1 8! adapted tol engage the peripheries ofthe rollers 7 as the links move by thesame Vtherefore the lugs and rollers serve las bracing means and prevent the links from buckling or distorting out of shape. The rollers? are located at the lower forward portions of the frames therefore -they are opposite the point upon the chain belt wherethe furrow slice is received upon the Inold board structure.

The operation of the. device is as follows The furrow slice is cut by the share l inthe usual mannerland passes upwardly and rearwardly alongthe same. This slice is received upon the link belt of which the links 16'are ycomponent parts and the weight of the furrow slice will move the links around the frames 6. Thereforethe furrow slice does not slip over lthe llinks butmoves with the same consequently as vthe slice is beingy turned friction is eliminated and the Copies' of ythis patent may beobtaincd for plowing operation may be more easily ac'- complished.v

Having described claimed, is zv l. A plow comprising a share provided at its rear'edge` with a plurality of recesses, ya longitudinally curved upwardly extending frame secured upon the share adjacentN the recess, rollers journaled within said frame and articulated linksconstituting an endless conveyer trained about said rollers, said links being' in close'con-tact with one. another and th'eframes and collectively serving as a closure for the frame.k

1n combination with a. plow share having its rearedge, provided with a plurality of incl-ined rectangular recesses, a plurality of longitudinally curved upwardly extending frames secured upon the shareadjacent said recesses, rollers journaledwithin each frame, and a plurality of articulated links constituting an endless conveyer trained about said rollers, said links being in close the invention what is contact with one another' and 'with the sides of the frame to form a substantialclosure for the frame.l

3. In combination with a plow share provided at its rear edge'with a plurality 'of recesses,.a plurality of longitudinally curved upwardly extendingirames secured at'their lower forward ends upon the underside .,'ofl

the share adjacent said recesses, a plurality'of rollers journaled within each lframe, and a" plurality of articulated links constituting an endless conveyer trained about said rollers, said links being in close contact with one another and with the sides of the frame to form a. substantial closure for the frame, said rollers having sections journale'd in the sides of the frame, the sides of the frame being provided with longitudinally extending` grooves connnunicating with the bearing points of said sections and plates secured upon the sides of said frame and serving as closures for said grooves.

In testimony whereof l affix lily-signature.
