MILO C. THOMPSON, OF SALEM, IOWA.
SPRING IENSIONED ROLLING CUTTER.
To all whom it may concern.-
Be it known that 1, MILO C. THOMPSON, a citizen of the United States, residing at Salem, in the county of Henry and State of Iowa, have invented certain new and useful Improvements in Spring -.Tensioned Rolling Gutters; and I do hereby 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.
This invention relates to plows, and more particularly to a spring tension means for rolling cutters for use on gang or sulky plows.
One of the principal objects of my invention is to provide a spring tension means for a rolling cutter, whereby the cutter may ride over a stone or other obstruction in the ground as the cutter comes in contact with the same.
Another object contemplates spring tension means such as described, embodying means for the prevention of torsion of the cutter standard, and means for normally holding the cutterin operative position.
With these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which like characters of reference indicate like parts throughout the several figures, of which,
Figure 1 represents a side elevational view of my invention, showing the same as attached to the beam of a plow, and Fig. 2 represents a vertical transverse sectional View of the line 22 of Fig. 1.
Referring more particularly to the drawings, the beam of the plow is represented by the numeral 5, and a pair of plates 6 is secured on opposite sides of said beam by means of bolts 7 passing through elongated slots 8 in ears 9, the ears on one of said clamps being provided wit-h teeth 10 adapted to coact with the teeth on the washer 11, so that bolts 7 may be held in any position longitudinally on slots 8, whereby the clamps may be fitted to plow beams of various dimensions.
The cutter standard 12, on the lower offset end 13 of which a rolling cutter (not shown) is secured, is slidably positioned at its upper end in a sleeve 14,011 which is Specification of Letters Patent.
Application filed ()ctober 10, 1913.
Patented July Me, 1914. Serial No. 794,455.
formed a lug 15, through which lug a pivot pin 16 passes, said pin being threaded at its inner end into a boss 17 formed on one of plates 6.
The collar 17 is secured on the upper end of standard 12, above sleeve 14, by means of the set screw 18, and said collar has formed thereon a downwardly projecting arm 19, which is interposed between lug l5 and boss 17, and which is provided with an elongated slot 20 through which pivot pin 16 extends. The arm 19 is ofiset from collar 17, to one side of standard 12, as is also lug 15 from sleeve 15, so as to position standard 12 at a suitable distance from beam 5. Lug 15 has a shoulder 21 formed thereon, and which is adapted to normally contact with a stop lug 22 formed on the adjacent plate 6.
A collar 23 is secured on the standard 12 below beam 5, and above ofi'set portion 13 of the standard by means of a set screw 24, and said sleeve is provided with a lug 2a to which one end of a retractile spring 26 is secured by means of a bolt 27, the opposite end of said spring being screw-threaded as at 28 and extending through an ear 29 on an arm 30 pivoted to the forward end of the adjacent plate 6 by means of one of bolt-s 7, a nut 31 being threaded on the upper end of the spring, whereby the same is adjustably secured to arm 30.
A coil spring 32 is interposed on standard 12 between the opposing ends of sleeve 14: and collar 23, and said spring tends to nor mally hold collar 17 in engagement with the upper end of sleeve 14-, while the spring 26 tends to normally sustain shoulder 21 in contact with stop lug 22, the combined action of the springs therefore, at all times tending to maintain the cutter pin in 0perative position, as shown in Fig. 1. However should the cutter strike a stone or other obstruction in the ground, the standard 12 will rise against the tension of spring 32, as the cutter rides over the obstruction, and at the same time the portion of the standard below the beam 5 will swing backward with pin 16 as a pivot, and against the tension of spring 26, and as the cutter passes beyond the obstruction, the standard,
12 will immediately, through the action of the spring, be swung in to operative position, it being noted that spring 32 normally tends to pull standard 12 forwardly on its pivot 16, said forward motion being limited however by stop lug 22, and thus the standard is normally held by reason of the action of the springs, against the tendency of the backward and upward movement of the cutter standard due to the contact of the cutter with the ground, at the same time allowing the cutter to pass over any obstruction in the manner previously described.
By reason of the arm 19, the standard 12 is prevented fron twisting as the same works up and down, and it may be added that ear 29 formed on arm 30 is long enough I combination and arrangement of parts, as
do not depart from the spirit of the invention, and the scope of the appended claims.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is;
1. In'combination, a plow beam, a cutter standardpivotally and slidably connected therewith, resilient means for normally holding said standard in vertical lowered position, and adjustable means for preventing twisting of said standard.
2. In combination, a plow beam, a cutter standard means for pivotally and slidably connecting said-standard with said beam, re-
ard, means for normally silient means for holding said 'standard in normal position, and adjustable means for v 1 resisting torsional strain on said standard.
3. In combination, a plow beam, a cutter standard, means pivotally and slidably connecting said standard with said beam, resilient means for holding said standard in normal position, and adjustable means connecting said standard with said connecting means for preventing twisting of said standard. j
1. In combination, a plow beam, a cutter-- standard, a'sleeve pivoted to said beam and justably secured to said standard, an arm on said collar movably secured at the pivotal axis of said sleeve, and means for normally holding said standard in lowered position.
5. In combination, a plow beam', plates secured thereto, a cutter standard, a' sleeve slidably positioned on said standard, a pin pivotally connecting said sleeve and one of said plates, a collar adjustably secured to said standard, an arm on said collar, said arm being held in parallel position with said beam for preventlng twisting of said standholding said standard in lowered position, aspring connecting said standard .with one of said plates for normally preventing rotation of said standard on its pivot in one direction and stop means for limiting rotation of said standard on its pivot in the opposite direction.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
MILO O. THOMPSON.
