Description
July 20, 1965 o. WATMOUGH FIELD MARKER Filed July 5. 1963 United States Patent 3,195,650 FIELD MARKER (Sliver Watmough, General Delivery, Lethbridgc, Alberta, Canada Filed July 5, I963, 53in. No. 293,592 1 Jlaim. (till. 172-126) My invention relates to new and useful improvements in field markers, particularly in field markers of the type described and claimed in myUnited States Patent Nos. 2,511,521 and 2,725,814.
The principal object and essence of my invention is to provide a field marker of the character herewithin described which includes a trash bar and means to adjust the angularity of the discs horizontally with respect to the main beam.
I have found it desirable not only to add a trash bar to my existing device in order to prevent furrowing between the outboard support and the main beam but, most importantly, to adjust the angularity of one or the other of the discs not only to facilitate in the tracking of the device but also to facilitate the efficient marking of the field upon which the device is to be used.
By providing the angular adjustment to the furrowing disc, I can utilize either a concave-convex disc or, alternatively, a planar disc thus making the construction and replacement of the device more universal.
Another object of my invention is to provide a device of the character herewithin described which includes various methods for providing the said angular adjustment depending upon the construction of the main beam.
A yet further object of my invention is to provide a device of the character herewithin described which is extremely simple in construction, economical in manufacture, and otherwise well suited to the purpose for which it is designed.
With the foregoing objects in view, and such other objects and advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:
FIGURE 1 is a perspective view of my device showing one method of adjusting the angularity of one of the discs.
FIGURE 2 is an enlarged top plan view of an alternative method of adjustment.
FIGURE 3 is a top plan view thereof.
FIGURE 4 is an enlarged perspective view of a further method of adjustment.
In the drawings like characters of reference indicate corresponding parts in the different figures.
Proceeding therefore to describe my invention in detail, reference to FIGURE 1 will show the main beam consisting, in this embodiment, of a longitudinally extending length of channel iron. Intermediate the ends thereof and extending at an inclined angle therefrom is the draft arm assembly 11 including aperture 12 at the distal end 13 thereof whereby the device may be attached to the towing means in the conventional manner.
Extending at right angles from the opposite side of the main beam 10 to the draft arm, is the outboard support 14 consisting of a U-shaped strap with legs i5 spaced and parallel and secured to the flanged edges 16 of the channel as by Welding. .A spacer 17 for stiffening purposes is situated between the legs as clearly shown.
A trash bar 13 consisting of a strap, is Welded by the end 19 thereof to the extremity 20 of the outboard support and extends forwardly in a diagonal direction to be secured by the end 21 thereof to the center of the main 3,195,656 Patented July 20, 1965 beam Iii adjacent the front end 22 thereof. This trash bar prevent trash from piling up in the angle 23' between the outboard support and the main beam 1% A front furrow wheel assembly collectively designated 23 is journalled for rotation in a substantially vertical plane adjacent the aforementioned front end 22 of the main beam and a rudder or steering disc assembly collectively designated 24 is journalled for rotation in a vertical plane adjacent the rear end 25' of the main beam.
Either one or both of these assemblies 23 and 24 is provided with means to adjust the horizontal angular relationship of the disc with the main beam within limits and in FIGURE 1 this adjustment is shown in conjunction with the front assembly 23 whereas in FIGURE 2, it is shown in conjunction with both of the disc assemblies 23 and 24.
In the embodiment shown in FIGURES 1 and 3, this adjustment means comprises a bearing tube 25 carrying a spindle 26 for rotation therewithin, said bearing tube extending through a slot 27 Within the main web 28 of the channel beam 10. This disc 29 which may be either planar or concave-convex, is secured to the end of the spindle extending through the bearing tube 25 and the spindle is prevented from displacement from the tube by means of cotter pin 30 extending through the other end 31 of the spindle.
An angulated adjustment bar 32 is apertured to fit over the bearing tube and is secured to the bearing tube adjacent the inner face 34 of the web 28 and nut and bolt assemblies 35 extend through each end 36 of the bar 52 and through apertures within the web 28 so that by adjusting the nut and bolt assemblies 35, the assembly is held firmly to the main beam Web 28 and at the desired horizontal angle thereto.
FIGURE 2 shows an alternative embodiment of the assembly 23 or 24 in which a stub shaft 37 is secured centrally to the adjustment bar 32, said stub shaft once again extending through a slot 27 within the web of the main beam Ill. The disc 29 is secured to the end 38 of the stub shaft with a not (not illustrated) engaging the threaded extremity 39 of the stub shaft. Once again the nut and bolt assemblies 35 secure the assembly to the main beam at the desired angular adjustment within the limits of the assembly.
FIGURE 4 shows a further embodiment particularly useful when the main beam 10 is made of solid stock rather than channel material. In this embodiment, a clevis 46 extends around each side of the main beam and is pivotally secured thereto by means of pivot pin 41. Stub shaft 42 extends from the end 43 of the clevis to hold the disc 29 by means of a cotter pin (not illustrated) passing through aperture 44 at the end of the stub shaft.
The angulated adjustment bar 32 is secured between the ends 45 of the clevis a by welding and the apertures 46 within the ends of the adjustment bar are screw threaded to receive screw threaded studs 47, the ends 48 of which engage the main beam Iii so that by adjusting the position of the studs within the angulated adjustment bar, the necessary horizontal angular adjustment of the disc assembly is obtained.
By providing the aforementioned limited horizontal angular adjustment of one or both of the disc assemblies, I am able to facilitate the tracking of the field marker depending upon the ground surface conditions and to provide the necessary furrow mark required.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claim without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as gaging discs carried by the end portions of said frame member at said one side thereof, at least one of said discs being horizontally angularly adjustable relative to the frame member, and means for mounting said adjustable disc on said frame member, said mounting means comprising a rigid horizontal elongated strap disposed at said other side of the frame member opposite from said adjustable disc, said strap, being angulated intermediate its ends to provide a fulcrum at its point of angulation and a pair of rangu'larly offset strap end portions extending in opposite directions from said fulcrum, axle means connected to said strap at saidfulcrum and projecting through a transverse opening in said frame member to said first mentioned side of the frame member, said adjustable disc 4 being mounted on the projecting portion of said axle means, said strap fulcrum rockably engaging said other side of said frame member whereby the horizontal angular relationship of said axle means and of said adjustable disc to the frame member may be adjusted, and a pair of adjusting bolts extending through apertures provided in said frame member at opposite sides of said opening, said bolts engaging the respective angularly offset end portions of said strap whereby to retain the strap in position on the frame member and whereby to permit adjustment of the strap through rocking about its fulcrum by loosening of either of said bolts and corresponding tightening of the other.
