PLOW MOLD BOARD WITH CLEANING APPARATUS Filed March 24, 1955 Zip.

"r'r'ow Morn BOARD 'WITH'CIJEANING g APPARATUS Willie C.Weiler,Swea Cityyl'owa I I 'Apiiut afinirrmh 24, i955, serial No.496,'481 '6-Clair'ns. (Cl.97-1"1'5) This invention relates to a plow mold board and par the general contour of the mold board rather than longitudinally in a generally reciprocated relation. The problem with the Coreth device is that the dirt tends to accumulate behind the movable slats and prevents the same from being returned to their normal position and thus presents an uneven mold board surface on which the dirt accumulates much faster than it would on a smooth surface.
It is an object of my invention to provide a self-cleaning plow mold board which always produces a generally smooth surface and provides for movement of certain portions of the mold board relative to the other portions thereof within the general shape and contour of the mold board surface.
More specifically it is an object to provide a mold board of slatted construction wherein alternate slats are shiftable generally longitudinally thereof within the general contour of the mold board surface to thus remove accumulations of dirt on said surface.
These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views, and in which:
Fig. 1 is a side elevational view of my new plow as connected to the rear portion of a tractor;
Fig. 2 is a rear elevational view of the plow structure shown in Fig. 1;
Fig. 3 is a vertical sectional view taken substantially along the line 33 of Fig. 1; and
Fig. 4 is a horizontal sectional view taken substantially along the line 44 of Fig. 1.
As illustrated in the accompanying drawings I show a conventional mounting apparatus for a farm plow designated as an entirety by the numeral 8 which is connected with a farm tractor as best shown in Fig. 1. This mounting apparatus is fixed to the lay 9 of the plow.
A mold board designated as an entirety by the numeral 10 is connected with the plow lay and has in the form shown a plurality of generally upstanding stationary slat elements 10a extending continuously upwardly from the plow lay 9. These stationary slats 10a are spaced apart to form guide Ways for the spaced movable slats 10b which are interposed between the stationary slats 10a.
The movable slats are in the form shown interconnect- Uni e es ary slats so that said'movable slats'will always tive to said stationaryslats.
ahd :guidingfun'ction stationary slat el'emeritsof the mold shown :the two cross bars 2,795,179 Patented June 11, v1957 ed on the back sides thereof as'bybeing welded to mov- 'a'ble cross has 1 1 and 12 at the respective upper and lower portionsthereof. "These cross cars are, of course, 'slidabl y mounted'with respect to the back sides of the stationary 'slats 10a and maintain the movable slats in constant alignment with the front surface oftthe stationconform to the general 'contour-oft he mold board even during their shifting movement. Asis shown in Fig. .3, said mold board follows a generally circular contour in order that this relationship lcan bemaintained. A strengthening and guidingcrossbar :13 is securely fixed as by being welded to the back side 'of the stationary slats and prevents rearward displacement of the movable slats rela- I'f necessary, of course, additional cross bars may be provided for increased strength and a bottom cross bar 14 is provided for positively interconnecting "the plow lay and the board. In the form 11 and 12 respectively :abut
the stationary cross bars 13 and 14 when the movable slats are in operative position.
Suitable means for-shifting the movable-slats 16b are pr'ovidedsuch as the bell crank actuating mechanism .illu'strated having abell crank 15 pivotally mounted on the plow mounting :app'ara'tus and has .a forwardly extending control rod 16 which in the form shown extends forwardly to a location within easy reach of the tractor operator. The bell crank 15 is connected at its other end to the shiftable slat assembly as best shown in Fig. 2 and this connection linkage 17 is longitudinally adjustable to facilitate positioning of the movable slats after assembly thereof. Obviously slight inaccuracies in the manufacture and assembly of the mold board slats would still permit a smooth continuous mold board surface to be produced extending upwardly from the lay 9 as best shown in Fig. 3, since the position of the lower ends of said slats 10b may be easily and quickly adjusted by said adjustable bell crank linkage 17.
The following is a description of the operation of my new self-cleaning plow mold board. Whenever dirt has accumulated on the slatted surface of the mold board 19 the bell crank 15 may be merely oscillated by the control rod 16 from the full line position to the dotted line position and this oscillation continued two or three times to break off said accumulations of dirt on said mold board. This, of course, is accomplished by the fact that alternate slats are moved relative to the slats adjacent thereto and the dirt layers are broken up and merely fall off from said slats.
It will be seen that I have provided a relatively simple yet highly efficient plow mold board of slatted construction wherein certain of the slats are mounted for longitudinal shifting movement relative to the adjacent slats to cause breaking and removal of dirt accumulated thereon. The cross bars 11 through 14 (inclusive) constantly maintain said slats in the surface contour of the mold board 10 even during the oscillation thereof so that said mold board surface is always maintained in a smooth condition.
It will, of course, be understood that various changes may be made in the form, details, arrangement, and proportions of the parts without departing from the scope of my invention which generally stated consists in the matter set forth in the appended claims.
What is claimed is:
l. A plow mold board comprising a plurality of slats disposed in adjacent side by side relation and forming a substantial portion of the surface area of said mold board, means providing relative longitudinal shifting movement between adjacent slatsto remove dirt clinging to'the surface :thereof. l t
2. A plow mold board comprising a plurality of slats disposed in adjacent side by side relation and forming a substantial portion of the surface-area of said moldboard,
certain of said slats being longitudinally shiftable relative to the other slats, means for producing longitudinal shifting movement of said shiftable slats relative to 'the other slats to remove dirt clinging to the surface ofzthe being' mounted in longitudinally shiftable relation'r'elaof the surface area of said mold board, alternate slats being shiftably mounted longitudinally of the adjacent slats, means positively interconnecting said shiftably mounted slats, actuating means connected with said shiftably mounted slat assembly for controllably producing longitudinal shifting movement thereof relative to adjacent slats.
4. .The structure set forthrin claim 3 and said actuating means having control linkage connectedtherewith and extending to a locationremote from the plow mold board to facilitate control from the motive power for said plow. t l
5. A plow mold boardcomprising a plurality of generally upstanding slats disposedin adjacent side by side relationand forming a substantial portion of the surface area of the mold board, alternate slats being mounted in stationary relation and the slats interposed therebetween tive to said stationary slats, a bell crank actuating mechanism having linkage connected with said shiftably mounted slats to controllably shift the same in a longitudinal direction generally upwardly and downwardly relative to said stationary slats, and remote control means connected with said bell crank mechanism for controllably actuating the same.
6. A plow mold board comprising a plurality of slats forming a generally concavely contoured mold board portion forming a segmental circular cross sectional shape and disposed in circumferentially arranged side by side relation on said circular contour to form a smooth curved surface, alternate slats being mounted in stationary relation and the slats interposed therebetween being mounted in longitudinally shiftable relation relative to said stationary slats, and mechanism connected with said movable slats for shifting the same in a circumferential direction generally longitudinally of said stationary slats to remove dirt accumulations on said slats.
