GANG-PLOW.

Original application filed October 12, 1916, Serial No. 125,288.

Specification of Letters Patent.

1917. Serial No. 166,368.

To @ZZ w hom t may concern.'

Be it known that I, JOHN B. BARTHOLO- MEW, a citizen of the United States,v residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Gang-Flows, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in gang plows and especially to improvements in gang plows in which the furrow-forming elements are disks. It will be understood, however, that my invention is not necessarily so limited.

In my application, Serial No. 125,288, originally filed May 15, 1913, renewed October 12, 1916, of which the present application is a division, I illustrated and described a plowing mechanism in which the present improvements can be embodied, upon which application Letters Patent 1,227 ,237 were issued May 22nd, 1917.

The object is to provide means for supporting the frame that carries thel disks which will permit the disk-carrying element to be readily guided when in operation and y also to be readily lifted out of plowing position. The frame has an inclined draft-'bar for attaching the disks in diagonal-series, and it is supported at the front end upon the guiding or steering devices, and supported at the rear in such a way that it can be raised first at the rear end, and afterward at the front end, on the guiding and steering devices.

Other objects will be apparent from the following description:

In the accompanying drawings `I have shown the embodiment of my invention which I now deem preferable. It will be understood, however, that numerous changes and modifications may be made.

0f the drawings: Figure 1 is a plan view of the entire plow; Fig. 2 is a side elevation; Fig. 3 is a rear elevation; Fig. 4s is a fragmentary side view, partly viu section, of the forward right-hand supporting wheel and associated parts;

Fig. 5 is a fragmentary diagrammatic plan view of one of the rear supporting wheels and associated parts;

Fig. 6 is a fragmentary diagrammatic rear` elevation of the parts shown in 5 with vthe frame in normal operative position;

Fig. 7 is a view similar to Fig. 6, but showing the frame in elevated position;

Fig. 8 is a fragmentary sectional view taken along the lines 8-8 of Fig. 1;

Fig. 9 is a fragmentary sectional View taken along lines 94-9 ofFigs. 1 and 8; and

Fig. 10 isa fragmentary diagrammatic view of the lifting cams taken from the right-hand side of the machine Referring to the drawings, it will be noted that the main frame as shown, comprises two.

principal parts, 1 and 2. As to the details of `these frame parts, there maybe variations, but in the construction shown the forward part, l, comprises a front cross bar 3, and the side bars 4 and 5. *The side bar 4 extends rearward throughout a part of its l length and is then bent inward to form the diagonal member 4a.` The side baro extends rearward fora short distance and is theny bent inward to form the diagonal element 5.

The rear ends of the diagonal elements it` ,i

are joined at 6.

The rear frame section 2 comprises a forward member 7 which is ydiagonally positioned parallel to the diagonal element- 4 of the front frame. .The frame section 2 also has a diagonal element l8 which is connected at its forward end to the rear end of the element 7 and which is positioned parallel to the element 5a of the front frame. A strut or brace'9 connects the forward end of the element7 with the rear part of the element 8.

The two frame sections are ieXibly con.- nected together by means of hinge devices at 10 and 10'. q

lVhile I have shown in the drawings but two frame sections, it will be understood that a larger number of sections may be used if found desirable.

in any well-known or preferred manner," andf as lthis feature of the mechanism formano part of my present invention, detailed description can be omitted; As showinthe Y The manner of con-Q V,structing `and connecting 'such additional frame sections will be readily apparent.

, the bracket. Y Thisl mechanism will be berief matter described in. detail. For preventingV disks 11-11 are provided with scrapers 13-13,y but asr to this feature also, there can be variation. ln fact,- so tar ascertain features of my invention are concerned, the

disks may be omitted entirely and plowing, elements of the moldboard type substituted.

For supporting; the 'forward corner ot the front trame section.y whichA is opposite to theplowingelements, l provide a ground Wheel la rigidlyrsecured to a rotatable shaft 15. This shaft 15 is mounted in bearing 167 secured; to the i't'rame member il, and in a bearing 17 secured tov a supplementary frame member 18. which extends 'from the front member 3, rearward, to the; point of connection between the members 1ra-and 5a. For supporting` the opposite forward corner for"v the front traine section.' l provide ya vground wheel 119, whichis loosely ,mouirted on theaxle 29 andwhich isor'mav be provided with a ground cutting flange as shown in Figs. 1 and 1.

gang plows, ySerial No. 671,955, filed January 18, 1912.

Referring in detail to the lifting mechanism, 45 is a short jack shaft parallel to the shaft 15, upon which the ground wheel 14 is mounted. Loosely mounted on the jack shaft 45 is a sprocket wheel 46 in line with a sprocket wheel 47 on the shaft 15. A chain 48 passes over these two wheels. Secured to the sprocket wheel 46 is a notched or serrated disk 49, and ad] acent to this disk and keyed to the shaft 45 is a large circular disk 50 formed at one point in its periphery with a roundednotchl. Adog52ispivotallymounted on the disk 50. The head of the dog carries a laterally extending roller 53 arranged to engage with the notched periphery of the disk 49, and a spring 54 which is interposed between the hub of the disk 49 and the dog 52, tends to press the roller 53 into engagement with the disk 49. A lever 55 is pivotally mounted on the bearing bracket 56 beneath the disk 49 and carries a roller 57 adapted to ride upon the periphery of said The lever also carries the roller 58 which is disposed in the plane of the dog 52. 59 is a coil spring interposed between the end of the lever 55 and an extension 60 of the bearing bracket 56, and tends to press the roller 57 radially inward against the disk 50. The upper endA of the lever 55 has connected to it a rope or cord 61, which extends forward to some convenient point within the reach of the operator.

Byreferring to Fig. 8 it will be seenv that when the roller 57 lies within the notch 51 in the disk 50, the roller 58 is in position to engage the rounded back or tail of the dog 52 and swings the dog on its pivot so that the roller 53 is withdrawn from engagement with the continuously rotating notched disk 49. If now the driver pulls on the rope 61 to swing the upper endof the lever 55 forward, the rollers 57 and 58 will be swung downward and the spring 54 will expand and cause the dog 52 to swing the roller 53 into engagement with the rotating disk 49.

In this way a4 driving connection is effected between the disk49 and the disk 50, so that the rotation of the former is transmitted to the latter.

Therotation of the disk 50 causes the notch 51 to be immediately moved away from the roller 57 so that when the rope 61 is released by the driver'and the spring 59 tends to return the lever 55 to its initial position, such a return is prevented by the engage ment of kthe roller 57 with the circular periphery of the disk 50. But as the disk 50 nears the end of its revolution, the roller 57 rines suddenly into the notch 51 under the action of the spring 59, and in this movement the roller 58 is caused to strike the tail of the dog 52 and to cause the disengagement of the roller 53 from the disk 49.

sprocket wheels 62 and 63. This shaft 64 is mounted in suitable bearings securedto the brackets 65, 66 and 67 mounted on the front member` 3 of the frame. The ratio `between the diameters of the sprocket wheels 62 and 63 is such thattheshaft 64 is given a half revolution for every completerevolution of -the shaft 45. Each of the brackets 65, 66

and 67 is formed in two parts, and between the parts of the several brackets there are mounted cams 68, 69 and 70. Pivoted to the forward outer ends of the brackets 65, 66 and 67 are levers 71, l72 and 73which carry rollers 74, and 76 adapted to engage, respectively, with the cams 68, 69 and 70. Connectedl to the rear end of the lever 71 is a chain 7 7 which extends over a suitable pulley 78 and is connected 'tothe spindle 21. A chain 79 isfconnected to the rear end of the lever 72. This chainy extends over suitable pulleys 80 and 81 and is connected t0 the lever 39a for the wheel 25; A chain 82 is connected to the rear end of the leverl 73. This chainextends over suitable pulleys 83, 84 and 85, and is connected to thelever 39b for the rear wheel 31.

Each of the cams 68, 69 and 70 is formed with anactivelifting portion 86, an inactive sustaining portion 87 'and an` inactive dropping portion 88. y It will therefore be clear that as each cam` rotates, it engages the corresponding roller to swing the correl' spondingI lever andmove the corresponding wheeldownward withrespect tothe frame. After the movement of the lever is once effected, the leverwill beheld in lifted position during the next succeeding part of the rotation of the cam.- f Upon further rotation of the cam,tthe lever will be released and permitted to returntothe lower position. as shown in Fig. 2. t n The'cams 68, 69 and L 76 are,` regularly spaced on the shaftso' that during rotation the cam 68 first comes into action,'then the cam 69, and finally the cam 70. f It willbe tion the rollers are still`- engaged by the cams, andthe frame parts andfpl'owing eleiwi . a frame, a series "of plowing disks connected to the frame, two wheels arranged tol runY on the top of the land'ffor, supporting the ments are maintained in lifted: positions. During., the next: half-revolution the cams successively disengage the rollers and per,-

niit the levers to move and release the frame Vparts'. and plowing. elements, and; permit` them to return successively toV plowing position.
