Serial No. 41,747.

An arbor 15 is arranged on the bolt between the arms 7 of the plates, and the said bolt is engaged by a nut 16 to hold the parts in place. A trailing wheel 17 is arranged at the front of the frame, the said wheel being journaled between the arms 18 of a yoke, comprising the said arms and a body 19. The body of the yoke has a journal pin 20, which engages a bearing block 21, held between the arms 8 of the plates 6-7-8, and the pin is secured in place in the bearing in the usual manner by a cotter pin and washer, shown. The yoke is free to turn on the journal pin with the trailing wheel.

A seat 20 is connected to one end of a spring plate 21, whose other end is secured to the body of the axle by means of the clips 18, and the said seat is to one side of the frame. A toothed sector 22 is secured to the body of the bracket 910 and to the body of the axle, as shown, and a lever 23 is pivoted near its lower end to a cross strap '24, which connects the body of the axle with the body of the bracket 9--10 at the center of the said body.

- The lever is provided with latch mechanism 25, which cooperates with the teeth of the sector to hold the lever in adjusted position, and a link 26 connects the lever above its pivotal connection with one of the arms 27 of an angle lever, consisting of arms 27 and 28. The other arm of the elbow lever is pivoted by means of a bolt 29 between the C-shaped plates 6-7S at the junction of the arms 8 with the bodies of the plate, and this angle lever is double as shown, consisting of two sections arranged alongside each other and spaced apart except at the connection of the link 26 therewith. A roller 30 is journaled on a journal. pin 31, extending between the two sections, and this roller is in. engagement with the front end of the plow supporting frame, to be later described, for permitting the said front end to be adjusted by means of the lever 23.

The plow supporting frame which is also substantially triangular is arranged between the side plates 1 of the wheel supported frame, and this plow supporting frame consists of a center plate 32 and side plates 33. The side plates 33 are approximately parallel with the plates 1 of the wheel supported frame, and they are connected at their front ends by a species of casing 34. This casing is approximately triangular in form, consisting of upper and lower portions, which 111g openings in the arms of are connected by vertical webs 35 at their front. Each of the side plates 33 has an angular portion 33 at its front end extending inwardly at an obtuse angle with respect to the body of the plate, and the said front ends of the side plates extend into the casing 34, the angular portions 33 being parallel with the webs 35.

Each of the angle portions has a bearing at its forward end which engages a bolt 36 connecting the upper and lower plates of the casing. Other bolts 36 connect the upper and lower plates of the casing in rear of the bolts 36, and the said bolts 36 are arranged on opposite sides of the central plate. The webs 35 at opposite sides of the central plate have forwardly extending lugs 37, which lap upon the opposite faces of the central plate 32, and are secured thereto by a bolt and nut 38.

The front end of the central plate 32 is offset upwardly as indicated at 32, and is provided with openings for permitting the engagement of draft apparatus. It is this upwardly offset portion 32 of the central plate that is engaged by the roller 30 before mentioned, and it will be evident when the lever 23 is swung rearwardly the roller 30 will be lifted, and will lift the front end of the plow supporting frame as indicated in dotted lines in Fig. 3. The rear end of the said frame is also connected to the lever 23 to permit the same to be lifted.

A shaft 39 is journaled in the arms 10 of the bracket 910 in openings in the said arms, and it will be noticed that each arm has a series of openings indicated at 40, the openings of each arm being in register to permit the shaft to be adjusted vertically.

This shaft 39 has a radial arm 41, which is connected by a link 42 to the lower end of the lever 23 and the end of the link adjacent to the arm ll has a series of openings 43 for receiving the bolt 44, which connects the arm to the link. By reason of the openings 43 the distance between the lower end of the lever 23 and the arm 4:4: may be varied. The shaft 39 is provided near each end with a rearwardly extending arm 45, and each arm has a slot 46 in its rear end.

A pair of cross bars 47 is arranged transversely of the plow supporting frame at the rear ends of the side plates 33, and the pairs of bars are connected at their ends by U- shaped clips 48, and belts and nuts 49.

,Each of the clips 48 is arranged with its body vertical and with one arm extending above the upper cross bar and the other extending below the lower bar, and the bolts 49 are passeddownwardly through registerthe clips and the ends of the bars, and are engaged by the nuts below the lower arms of the clips.

The upper bare? of the member has near each e'nda pair of laterally spaced bearing lugs 50, and each pair of lugs has registering openings. Each of the arms 15 extends between the adjacent pair of lugs, and the arms are pivoted to the lugs, the pivotal connection passing through the openings of the lugs and through the slots 16 of the arms.

A plow beam 51 is pivoted to the rear end of each side plate at the front end of the beam, and each beam passes between the bars 47. Each of the beams 51 has a bearing 52 at its front end, and each of the bearings is received between a pair of lugs 53 on the rear end of the adjacent side plate 33. The lugs extend from the upper and lower edges of the side plates, and each lug has a series of openings as shown, for receiving the belt 54 which connects the beam to the lugs. The bolts 5% pass through the bearings 52 and through a pair of registering openings in the lugs, the arrangement being such that the beams may swing laterally toward and from the central plate 32.

Since the beams 51 are between the members of the pair of bars 4:? it will be evident that when the lever 23 is swung to oscillate the shaft 39 the rear end of the plow supporting frame together with the beams 51 will be raised or lowered, depending upon the direction of oscillation of the shaft 39.

A beam 55 is connected with the central plate 32 by means of oppositely arranged clamping plates 56. These plates 56 are arranged on the outer sides of the beam and the plate respectively. and they are clamped together by bolts and nuts 57. the bolts extending through openings in the ends of the clamping plates above and below the beam. The beam 55 inclines forwardly toward its lower end, and each of the beams 51 is areshaped, curving downwardly and forwardly at its lower end.

Each of the beams 51 is provided at its lower end with a series of openin s 58 for receiving the journal pin on a disk, or for permitting the connection of a plow indicated at 59 in Fig. The journal pin of the disk may be engaged with either opening of the beam to permit some degree of adjustment.

A splitting or lister plow 0 is connected with the lower end of a double standard 62. The sections of the standard are spaced apart from each other. and the bolts and nuts ()3 which connect the shank with the standard are passed between the sections. the shank fitting against the front ed es of the sections.

The sections of the standard extend on opposite sides of the beam, and each has an arc-shaped series of openings 65 at its up- .1.

second bolt 66 is passed through registering openings in the sections of the standard and in the lower end of the beam, the bolt 66 being below the bolt 65.

By means of the bolt 64 the plow may be adjusted with respect to the beam. The beams 51 are moved toward and from each other by means of a lever 66, which is pivoted to a bracket 67 secured to the .rear end of the central plate 32, and having a toothed sector 68 above the said plate. The lever 66 has latch mechanism 69, cooperating with the teeth of the sector to hold the lever in adjusted position, and a link 70 connects the lever with a shoe 71, mounted to slide on the central plate in front of the cross bars 47. The shoe has a pair of bearings 72 at each side of the plate, and a bearing plate 73 is secured to each beam on the inner face thereof a little in the rear of the cross bars 47.

Each of the bearing plates has bearings 74 at its ends, and a plurality of pairs of bearing links 75 and 76 connect each bearing plate with the adjacent side of the shoe. The members of each pair of links are spaced apart vertically, and are connected to the shoe and the bearing plate by bolts and nuts 77, which pass downwardly through the ends of the links and through the bearings 7 2 and 74:. When the shoe 71 is moved longitudinally of the central plate 32 by means of the lever 66, the angle between the links 75 and 76 and the plate 32 will be changed to move the beams 51 toward or from the central plate.

The lJ-shaped clips 48 are guide blocks,-

the bodies of the said clips moving in channel shaped guide members or plates 79, which are secured to the vertical members 5 of the axle by clips 7 9. Each of the clips has a groove for receiving the vertical portion of the axle, and the ends of the clip are connected to the channel shaped guide by bolts 80. The lower ends of the guide members 7 9 are connected to the side plates a of the wheel supported frame by bolts 81. These guide members prevent longitudinal movement of the frames with respect to each other when the said frames are moved verticallv.

The clips 48 move in the channel when the plow supporting frame is moved vertically by means of the lever 23. This lever 23 raises and lowers the plow supporting frame and the plows bodily, the roller 30 lifting the front end. The rear end is lifted by the arm of the shaft 39.

'When it is desired to detach the plow supporting frame from the Wheel supported frame, the wheel supported frame is lifted to disengage the bodies of the clips 4:8 from the guide members 78. In order to permit this lifting movement the arms 45 are disengaged from the lugs 50. When new the rear end of the wheel supported frame is lifted the clips will move downward in the guide members until they pass out through the lower ends thereof. The wheel supported frame is now pushed forwardly and the offset portion 32 of the central plate 32 rolls off the roller 80.
