Application filed November To all tau-710m it. may concern:

Be it lrnown that 1, Jose F ERRY GARCIA, a sub ectof the King of Spain, and resident 'of Hzrbana, Cuba, have invented certain new and useful Improvements in Plowing Machines, of which the following is a specification.

This invention relates to plowing machines, and its object is to provide an improved machine of this class embodying an improved share which is arranged for rotation and operates somewhatlike an anger in plowing and loosening the soil.

Another object v of this invention is to combine in a machine a plurality of said earth working plows or shares, and to provide means for regulating the depth at which they operate inthe soil.

Another obj ect of the invention is to provide means for raising the plows and holding them in raised position where desired.

A further object of theinvention is to provide gear mechanisms for transmitting motion from the motor shaft on a driving vehicle to said revolving plows mounted on the same vehicle.

The invention; is described with reference to the figures of the annexed drawings, in which: I

1 is a side elevation of .a plowing machine constructed in accordance with this invention. I

2 is a top plan view of the same.

Fig. 3 is a longitudinal vertical section, on line 3-3 of Fig. 2.

Fig. t is a partial longitudinal vertical section, on line 4-4 of Fig. 2.

Fig. 5 ;is a cross vertical section, on line 5-5 of Fig. 2. I

Figt ti i's a cross vertical section, on line 66 of Fig. 2.

And Fig, 8 is :a cross vertical section, on line $8 8 of Fig. 1. "I

In thedrawings, l designates an ordinary chassis ofa motor vehicle mounted on a front horizontal shadt 2- having the direction wheels 3 and ,on ajrear horizontal "shaft 4 bein provided with the traction wheels 5, whic as is-nsual in motor vehicles, receive motion from an engine '6 fixed on the here Part of the chassis,

011 the freer shaft dot the 'inotor vehicle a substantially fiat frame :7 mounted for rocking movement Whose Sides are onthe in- 12, 1923f Serial No. 674,328.

nersides of the holsters of chassis l and are raised above the same owing to the fact that the axle-boxes 8 of frame 7 are below the sides of said frame (Fig. The sides of frame 7 terminate at their front ends in smooth vertical sectors 9 connected together by a pair of cross bars 10. Said sectors are concentric with and on one side of the corresponding sectors 11, which rise from a cross plate 12, and are secured attheir bases by wings 12 and screws 13 to the inner faces of the holsters of chassis 1. The stationary sectors 11 are connected together-by a transverse plate- 14. secured with screws. The stationary sectors 11 have at their inner arcuate edges rack teeth 15 for meshing with gear pinions 16 which are secured on the ends of a horizontal shaft 17 mounted on bearings 18 arranged on the upper ends of the moving sectors 9. Motion is transmitted manually to shaft 17 by means of a crank, 19 fixed on the end of a short horizontal shaft- 20 mounted on brackets 21 connected to brackets 22 which are fixed on one of the cross bars 10. Said short shaft 20 carries a gear pinion 28 which meshes with a gear pinion 24L fixed on the center of the shaft 17'. The moving sectors 9 may be secured inan'y required position with respect 8 to stationary sectors 11 by means of a catch 25 Fig. 4) which passes throughthe upper crossbar 10 and is arranged in a spring casing -26 andladapted to be inserted in one of a the three or more openings of a block 27 which is fixedfto cross plate 14. Said catch 25 is provided with a smallhandle 28 by which it may be operated. I

The moving sectors 9 are reinforced by braces 29 which lead from upper extensions 7 projecting from the sides of the rocking frame 7 and from such extensions 7' braces 30 extend rearward-1 and are connected to standards 31 which are integrally connected to the rear parts of the sides of frame 7. Said standards re connected together b a cross bar "32. On bearings 33 fixed below the lower bases of extensions 34 which .pr0 jeot downwardly from the sidesof frame 7, at the rearjparlts of the same, is rotatably mounted a loose horiZontalsha-ft 35 which acts as a "pivot t "a plurality of vertical frames separatel and .equidistantly distributeii on said pivot 35 and supported on the latter and on another horizontal shaft 37.1115: 1 a th'roughisaidframesf36 on bearings each one closed at the sides'by a block 38 sliding on a slot 38' formed in each frame 86. Each block is secured by a pair of screws 39. Said shaft 37 has cranks 40 at its ends, and said shaft has gear pinions 11 which mesh with gear sectors 12 formed at the rear end of each side of the frame 7 (Fig. 1). Inclined bars 43 project rearwardly and downwardly from said sectors and have extensions 3 which extend below the pinions l1. On the base of a recess .1. 1 formed on the rear upper part of each frame 36 are secured two short standards l5 and 46 spaced apart and on which is mounted a longitudinal crank shaft 47. The cranks of the various shafts 4:7 are in the spaces between the said standards. All the crank wrists 47 are connected together by

bars

48 and 4,9 which are secured together by bolts 50. The rear ends of crank shafts 47 are provided with beveled gear pinions 51 which mesh with beveled pinions 52 fixed on the upper ends of vertical shafts which are mounted in bearing pieces 54L secured by screw-bolts 55 to the rear part of each frame 36. On the lower ends of said vertical shafts 53 are secured beveled gear pinions 56 which mesh with beveled gear pinions 57'li2red on the rear ends of substantially horizontal or slightly inclined shafts 58. Said shafts 58 are mounted in bearing pieces 59 fired by bolt screws 60 to the lower part of each frame 86, said shafts 58 forming stems which are integral with the nucleus of shares or plows for working the soil. Said plows at their front half portion are of helical form as at 61 and each terminates in point 62. At the rear part the helix is widened and cut in a diamet-ral plane to form a mould board 62 the function whereof is to guide the ground raised through the. helical part 61 and to invert the same.

Motion is transmitted to the various crank shafts 47 from the driving shaft 6 1 by the cross shaft 65 which transmits power to the shaft 4: of the traction wheels 5-by means of sprocket wheels 66 and 67 and endless chain 68. A second cross horizontal shaft 69 is mounted behind the traction wheels 5 of the vehicle, in bearings 70 formed below the downward extensions of the sides of frame 7. On the ends of said shaft 69 are sprocket wheels 71 connected by endless chains 72 with sprocket wheels 73 fixed on shaft 4 of the vehicle. Shaft 66 has a beveled gear wheel 74 applied thereto and a beveled gear wheel 75 loose on same shaft, which beveled gears 74 and 75 mesh with the diamet i ally opposite sections of a lower beveled gear crown of a large horizontal wheel 76 whose trunnions 77 are mounted on brackets 78 and "79 each of which comprises four arms which are integrally connected to four mountings 80 fixed to the sides of frame 7. Said crown 7 6 meshes at the rear end of its longitudinal diameter with a beveled gear wheel 81 fixed on the front end of a longitudinal horizontal shaft 2 which is mounted in a bearing piece 83 i'xed by bolt screws 841 at the upper part of the central frame 36. Said shaft is integrally connected to the respective crank shaft 17. Frame 7 presents at the rear part a cross bar 85 connecting the sides of said frame by means of upwardly directed wings 86 which extend on both ends beyond those sides to act as an upward stop to frames 36. Said cross bar 85 has a central portion 87 of semicircular form for acting as guard to the beveled conical wheel 81.

On the rear part of frame 7 is securely arranged a seat 88 for the operator of the plows 61. On the chassis 1 is securely fixed the usual seat 89 for the driver of the vehicle. On frame 7 'an be arranged an awning 90 supported by standards 91 and 95 3 properly secured on the sides of frame 7, and in like manner on chassis 1 there can be arranged a section of awning 93 supported by standards 9 1 securely listed to the rear part of engine 6.

The operation of this machine is as follows: Through the described gear mecha nisms, motion is transmitted from shaft 4; of the traction wheels 5 and while the vehicle is in motion, to the plows or revoluble shares 61, which, being slightly inclined, operate in an auger like manner, boring the ground as the machine travels, the earth going up through the spirals of the wider helix 63 and dropping down beyond to be inverted. When it is desired to change the depth at which the shares 61 are to operate, catch 25 is pulled back to disconnect it from block 27, and crank 19 of shaft 20 is turned in one direction or the other so that shaft 20 may cause the rotation of shaft 17 carrying the gear pinions 16 which run on the arched racks 15 of the stationary sectors 11, cans ing the whole frame 7 to rock with the mechanisms supported thereon around the hori zontal pivoting shaft 1. The shares or plows 61 are caused to penetrate more or less into the ground as may be required.

hen the operation of the plows 61 is to be suspended, that is, when the machine is to travel without working, the plows are raised by actuating the cranks 10 of shaft 37, which on causing the gear pinions 11 to rotate, which by meshing with the gear sectors 42 cause the rockin of the frames 36 on the pivoting shaft 35 to be turned until the points 62 of plows 61 come up fromthe ground. .Vhen it is desired to put the plows in operation the proceeding is reversed.

It should be understood that the details of construction of the mechanisms of support and of transmission of motion to the revolublepshares can be varied within the spirit of the invention, and within the scope of the appended claims.

'What I claim is 1. A plowing machine comprising a motor vehicle, a rocking frame mounted on the rear axle of the vehicle, means for controlling the position of the rocking frame with respect to the chassis of the vehicle, a frame pivotally mounted on the rear part of the rocking frame, an earth working element rotatably mounted at the lower part of said last named frame and means to actuate such element, such actuating means being operative in only one position of the last named frame but in any of the adjusted positions of the rocking frame.
