PLOWING MECHANISM.

Specification of Letters Patent.

Patented Oct. 8, 1912.

Application led March 2, 1912. Serial No. 681,161.

To all whom it may concern Be it known that I, CHARLES L. ARCHAM- BEAU, residing at Geyserville, in the county of Sonoma and State of California, have invented a new and Improved Plowing Mechanism, of which the following is a specification.

This invention has for its object to provide a new and improved construction of plows and more especially comprehends an improved adjusting means designed for conveniently and quickly setting the plows for back-furrowing or dead furl-owing and for adapting the machine for being readily conveyed about the field.

My invention consists in the peculiar construction and novel arrangement of parts all of which will be hereinafter fully described, specifically pointed out in the appended claims and illustrated in the accompanying drawing, in which Figure l, is a perspective view of my improved plowing mechanism. Fig. 2, is a plan view, the lateral adjustments oi' the plows being indicated by the dot and dash lines. Fig. .8, is a longitudinal section of the same, the carrier or truck wheels being shown adjusted for conveying the machine with the plows out of the ground, the plowing position of the latter and the correlation of the carrier wheel devices when at that position being indicated by dotted lines.

In the practical arrangement, my invention includes a central longitudinal beam l on the front end of which is bolted a head frame in the nature of a horizontally disposed circular bar 2, having an eye portion 20 at the front end for receiving the draft clevis 3.

10 designates a shifter bar, the reciprocal movements of which control the adjustments or sets of the plows.

4: designates a cross bar that extends over the front end of the shifter bar 10 and it has its ends connected to the head frame 2, bythe bolts 40 that form stud or fulcrum bearings 41 for the oppositely disposed segmental gears 6, the gear sections of which mesh with the opposite rack or gear edges 11-11 of the shifter bar 10, the latter also having a longitudinal slot l2 for engaging a pendent guide 51 on the cross bar 4.

7 7 designates a pair of oppositely disposed levers and these are fulcrumed on the stud bolts 40 to oscillate in the horizontal plane. Each lever 7 is bolted to the segmental gear 6 at its corresponding side, and the rear ends thereof are hingedly connected to the front ends of the plow beams 70 that carry the plows 71 of usual construction.

8 designates an arched shaped shaft journaled crosswise of the head frame 2, in. brackets 25 on the underside of the said frame and the stub ends S0 of the said shaft carry carrier wheels 552-82.

9 designates the shifting lever mounted on the rear end of the main beam, and having the usual rack and pawl devices.

v90 designates a link rod that joins with the rear end of the shifter bar 12.

95 designates a lifting lever fulcrumed on a bearing 96 on the rear end of the beam l and its lower end supports the rear carrier or lifting wheel 97 which is so mounted with respect to the plow and the beams that when the lever 95 is swung back to the position shown in F ig. 2. the plow frame with the plows is elevated to raise the plows from thc ground. To sustain the frame and the plows at a proper rise above the ground the arched cross shaft 8 has a pendent crank 86, which, through the link rod 87. joins with the shifting lever 9, the forward movement of which referred to, swings the front carrier wheels down and in consequence raises that end of the machine.

From the foregoing description taken in connection with the drawings, the complete construction, the operation and the advantages of my invention will readily appear.

By reason of the construction of the parts, as described and shown, the shifting of the bar 10 forwardly works the gears G, and in consequence spreads the plows, see dotted line X, and by shifting the bar 10 rearwardly beyond the normal position shown and as indicated by the arrow y/'draws the plows together. it being understood that by reason of the hinged connection between the levers 7 and the plow beams, the plows retain their parallel alinement with the main beam under all of their adjustments.

lVhat I claim is:

1. A plowing mechanism comprising a central beam, a plow carrying beam at each side of and parallel with the cent-ral beam, a support on the forward end of the central beam, horizontally swingable levers mounted upon the said support, hinged connections that join the plow beams with the levers, and

lever controlled means for simultaneously shifting the swingable levers to set the plows laterally to or from the central beam.

2. The combination with the central beam and the plow carrying beams located one to each side of and parallel with the central beam, of means mounted on the central beam, said means including pivotal connections with the plow beams for laterally shifting both plow beams in unison toward or from the central beam.

8. The Combination with the central beam, the plow carrying beams located one to each side of and parallel with the central beam, a headr frame mounted on the forward end of the central beam, a lever pivotally mounted on each side of the head beam to swing in the horizontal plane, hinged connections joining the said levers with the forward ends of the plow beams, and shiftable rack and gear devices connected with the swinging levers for swinging them upon their fulcrums whereby to set the plow laterally with respect to the central beam. n y 4. In a plowing mechanism of the-character described, the combination with the central beam, an annular head plate mounted on the forward end thereof, a cross bar having pivot bolt connections with the head plate at the outer ends thereof, a lever mounted on each of the pivot bolts to swing in the horizontal plane, plow carrying beams pivotally connected with the said levers, a segmental rack connected with each of the said levers, having the pivot bolts as their' axis, a double faced rack bar for engaging the two segmental racks, and means for actuating the rack bar.
