GANG OR OULTIVATOR PLOW.

SPECIFICAA'JIIONl forming part of Letters Patent No. 634,358, dated October 3, 1899.

Application iiled November 4, 1898. Serial No. 695,465. (No model.)

lb all whom t may concern:

Be it known that l, JOHN THOMAS LUCAS, of lVasco, in the county of Sherman and State of Oregon, have invented a new and Improved Gang or Cultivator Plow, of which the following is a full, clear, and exact description.

The principal object. of my invention is to improve upon the construction of gang or cultivator plows for which Letters Patentwere granted to me June 27, 1893, No. 500,405.

A further object of the invention is to provide a rear or guide wheel which will have but slight frictional engagement with the land and to provide means forsimultaneously raising and lowering all of the shares and for leveling the plow when necessary.

A further object of the invention is to provide an adjustable clevis and a simplemeans for operating the same and to provide the shares with detachable landsides, whereby the shares will be prevented from slipping uponhilly or upon uneven ground.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding partsin all the figures.

Figure'l is a plan view of the improved plow. Fig. 2 is a side elevation of the same, and Fig. 3 is a detail perspective view of the shank for the rear shaft and the share belonging to the shank.

The frame of the body of the implement consists, primarily, of two side beams A and B and two intermediate beams Gand CC The right-hand side beam Bis of zigzag shape, being bent to form a series of steps, (designated as b.) The intermediate beams C and C eX- tend beyond the front portion of the two outer or side beams, while at the rear end of the plow the two side beams are brought together and the projecting forward ends ofthe intermediate beams C and C are given a downward inclination, as shown in Fig. 2.

The side and intermediate beams are connected or braced together by cross-bars 10l and 1l, while a cross-bar 12 extends through the inclined projecting portions of the intermediate beams, and another cross-bar 13 is provided for the said projecting portions of the intermediate beams at their forward extremities.

Two parallel axles D and D' are provided for the frame of the plow, the said aXles being located near the front end of the plow and are journaled in suitable bearings carried by the side frames A and B. The forward axle D is provided with a crank-arm 14 at its righthand end, carrying a supporting-wheel 14:, while the rear axle D' is provided with a crankarm 15 at its left-hand end, which carries a supporting -wheel 15, the two supportingwheels being practically in transverse alinement.

A hand-lever 16 is secured upon the straight portion of the forward axle D, near its crankarm, and the said hand-lever is provided with a thumb-latch 17, adapted to engage with a suitable rack 18 on the frame, and a second hand-lever 19 is secured upon the straight portion of the rear axle D', near its crankarm, the lever 19 being also provided with a thumb-latch 20, adapted to engage with a rack 21, also secured to the frame. By manipulating the lever at the left of the frame and attached to the rear axle the plowshares may be raised and lowered'and made to travel at any desired depth in the soil, while through the medium of the lever attached to the front axle the wheel that travels in the furrow may be raised and lowered independently of the landside-wheel, so as to level the plow.

At the front end of the plow-frame a clevis 22 is located, the said clevis being of angular construction. One member of the clevis is adapted to travel upon the front connectingrod 13, while the other member is provided with a series of apertures 28, adapted to receive a draft device, and the clevis is llaterally shifted through the medium of a handlever 24, fulcrumed, preferably, upon the connecting-rod 12, as shown in Figs. 1 and 2,

the forward-end of the leverhaving shifting engagement with the clevis. Then the clevis is constructed in the manner set forth, it may be shifted to vary draft to and from the land while the plow is in motion, and the loop connection 24:, which is provided between the clevis and the lever, serves to prevent the lever binding on uneven ground, and the loop connected with the clevis-lever 24 is con- ICO nccted with the clevis through the medium l drivers seat 25, said seat being mounted y upon the rear portion of the frame.

The plowshares 2G are somewhat rectangular in general contou r, but their forward faces are coneaved and their rear faces convexed, and one or more of the plows are provided with a landside 27, the landsides being attached to the rear face of the share by means of lugs 2S, and where a landside connects with a share the outer face of the landside is more or less convexed. The end of a landside farthest removed from a share is connected with said share by a. brace 30, and the said braces and likewise the landsides are detachably attached tothe shares, as the shares are reversible, both their upper edges 96 and lower edges 2&3" being cutting edges.

All of the shares with the exception of the rear share are connected with the zigzag bar B through the medium of shanks 2S), the upbottom of the sleeve 32, and upon the upper end ofthe shaft an arm 37 is secured, which usually extends forwardly and is prevented from moving toward the land by a pin 38, with which it engages, the pin being carried by the frame; but the arm is capable of moving to the right upon a suitable guide 39, provided for it. Thus it will be observed that the guide-wheel t will take care of itself when the plow is turned and need not be 0perated by hand.

rlhe landsides 27, attached t0 the shares, prevent the said shares from slipping upon hilly or upon uneven ground. The landsides are so shaped as to dispense with most of the friction common to other landsides, since the lower edges of the landsides are sharpened their full length, whereas the ordinary landsides are very wide at the bottom. The imi proved shares and landsides are especially adapted to plows supported upon three wheels, as there is little pressure between the land and the bottom of the shares and their landsides, thus reducing the draft to about onehalf less than that of other plows turning the same width.

per ends of the Shanks being,` provided with f heads that are bolted or otherwise secured to the steps l) of the said zigzag bar; but the shank of the hub said washers servingas caps and 5.

they form dust-protectors and likewise prevent the earth working into the hub of the said guide-wheel. By constructing the rear sha-nk 3l as shown in Fig. 3 it is made compact and strong, and but one piece is necessary where two pieces have heretofore been e m ployed.

The shaft 33 is provided with a collar 36 near its lower end, which engages with the which l frame, of a plowshare having a shan k attached l t l The landsides can be readily detached when it is necessary to reverse the shares or to remove them for sharpening.

Having* thus described my invention, I claim as new and desire to secure by Letters Patent l. ln a gang-plow, the combination with a to the share and fixed to the frame, a sleeve carried rigidly by the shank, a vertical shaft mounted in the sleeve, a rearguide-wheel supported by the vertical shaft at the lower portion thereof, an arm attached to the vertical shaft and extended forwardly, a guidel over which the arm moves, and a pin carried by the frame and serving to limit the movement of the arm in one direction.

2. A plow, having a share, a landside connected with the share and having a cutting or sharpened lower edge, and means for bracing the landside against the share.
