Patented May 8, 1945 UNITED; STATES; PATENT OFFICE COLTER; I c Arthur Laitinen, Kimball, Minn. Application May 6, 1944, Serial No. 534,433 7 2 Claims (01. 97-209) This invention relates to a colter device, I

An object of the invention is the construction of a simple and very efficient colter device which will prevent the plow from lifting out of the ground by eliminating the gathering of cornstalks or weeds of any kind in frontof the colter device. r g

Another object of the invention is the construction of a very efficient and novel frame, mounted in a novel and efficient manner upon the standard of the device, which standard is adapted to be attached'to the common plow beam of aplow.

A still further object of the invention is the construction of a novel and efiicient colter device in which the frame will. efliciently slide or pass over, as a runner, foreign'matter, such as stalks and the like, and which frame will also have a slight pivotal or turning movement upon its supporting standard, whereby the life of the device is increasedby eliminating the possibility of the frame being broken off the standard.

With the foregoing and other objects in view, my invention comprises certain novel construc-' tions, combinations, and arrangements of ,parts as will be hereinafter fully described, illustrated in the accompanying drawing, and more particu larly pointed out in the appended claims.

In the drawing:

Referring to the drawing in which the pre- Figure 7 is an enlarged fragmentary perspective 7 I l designates an ordinary plow beam and 2 a mold ferred embodimentof this invention is illustrated,

board. The colter device comprises a substantially V shaped frame 3 upon the inner or lower end of which is pivotally mounted colter wheel 4; The V-shaped frame is curved upwardly at its outer end and its sides 5 are connected at their bottom edges by a runner bottom 6, Fig. 4. This bottom permits the frame to slide over corn stubble and weeds and the like, and should any dirt'ha'ppen to fall between the sides 5 and onto the, runner bottom 6, "the same will readily pass out of the opening I and onto the ground.

The standard 8 extends through two parallel webserrigw that are integral with the sides 5 of the V-shaped frame. These webs9 have registering'apertures l0 through which the lower end of the standard 8 extends. A horizontal slot II registers/with the space between webs 9 and in this space is placed collar 12; collar [2 fits around the standard 8 as clearly seen in Figures 5 and 6. The collar I2 is provided with an enlargement l3 and into this enlargement extends a set screw I4 which is adapted to impinge tightly against the standard 8 (Fig. 6), thereby locking the frame 3 in an adjusted position upon-the standard.

The slot ll permits the frame 3 and wheelv 4 to have a slight horizontal movement upon the standard, as indicated by the arrows A, Fig.2,

whereby the life of the device is increased be-] cause of this yielding action in case the wheel strikes a large rock or considerable stubble, that might otherwise injure the device ifit were not i for the novel construction and movement, as just described- A cotter pin I5 is placed in the lower end of the. standard 8, and on the standard just above cotter pin l5 i a washer It. This structure keeps the standard 8 from being accidentally pulled out.

of the webs 9 and collar 1 2, but does not interfere with the operators ready adjustment of the frame and its wheel to the desired position.

' The standard 8 is mounted on beam I by passing the standard through-two loop bolts l1 (Figs.

8 and 9), with one of these loop bolts placed above and onebelowthe plow beam I, Suitable sleeves H! are placed on these loop bolts in engagement with theplow beam I, and on the sides of the plow beam l are strap irons I9 through which the loop bolts extend. Suitable nuts .20 are on the outer ends of the loop bolts I1 in engagement with the outer strap iron l9, whereby the standard 8 is securely attached to the plow beam l. Of course, it will be understood that the standard8 fits tightly into the loops of bolts ll,

The frame 3 is formed r I I is tosay, the upper or outer .half curves upward m r "sly whereas the .inner or lower half .curve downsufficiently to prevent'any sliding movement-oi? the standard upon'beam I when in a fixed assems bledposition thereon. C a From the vforegoing description itis to be un derstood that I have provided a standard upon which is adjustablymounted a wheel-carrying frame, the adjustment being novel as Well as the frame,iwhereby a highly eflicient device is producedthat will bea big help during plowing time, because it, will slip over solid objects like What I claim is:

A colter,'compr1sing a V-shaped wheel-car rying'frame, including two upstanding sides; said sides-at outer'ends having a runner bottom invtegral withonly their lower portions, said runner bottom having-its inner end near the middle of said frame, a pair oi -transverse parallel'webs en- 1 tirelybetweenthe top andtbottom edges of said upstanding sides and .integral therewith, the

rocks, stumps, etc.,-in stead of breaking off the counters'hank.

It is to be understood that this colter-'device'-- can be vfastened to anyordinary plow .and, sfure lower web .of' said pair having one of its side a edges contiguous to v therinnerend or :said runner bottom, whereby an opening is formed between -said lower web and the inner end of said runner i "bottom, one of said upstanding sides, being pro- 4.5;
