with respect to the draft devices, whereby the draft is communicated from the whiffle 3 frame, instead of throug frame, which glves a steadier and lighter draft.

. using the frame with a tree to the plows throu h the rear of the the front of the A further feature" of the invention is that the low point upon manipulation of a suit able ever will be drawn out of the ground by Means are ang o plows, and also for varying the wk lt-h'as well as .the depth of" the furrow. The draft is not applied to'the pole, and fall, thereby avoiding pressure on the horses necks. The pole is locked, to insure a straight travel when the plows are in the ground, butwhen the plows are lifted the pole is automatically unlocked, to allow a turn to be made.

The invention is illustrated in the accompanying drawings, in which Figure-1 is a perspective view of the implement. Fig. 2 is a top plan view. Fig. 3 1s a sectional elevation on the line '3-3 of the draft animals.

line 44 0 Fig. 2, with some section Fig. 5 is a front elevation.

The main frame 6 is substantially rectangular in outline, being preferably formed of a wrought metal bar, and having an arch 7 at V the front end of one side to allow the furrow wheel 8 to turn under. The beams which support the plows consist of arallel bars 9. Two sets of these bars, as we as two lows 10, are shown. The bars 9 extend lengt wise of and rest u on the frame and are fastened by clips and bolts indicated at 11. This permits the two sets of bars to be spaced apart any desired distance, in order to vary the width 'of the furrows by loosening the clips and bolts and'moving the sets laterally to desired position. The plow. standards 12 -areheld at theupper ends between the respective pairs of bars, bymeans of bolts 13,

l the depth of the plow.

' t 1s also characterized by improvementsv rovided for.

and the pole is free to rise Fig. 2. Fi 4 is a similar elevation on the. arts also-in ered.

and the tilt of each plow point may be varied by means of a set-screw 14 which is talpp'ed ears through the head-of thestandard and at its point upon'a cross-piece 15 which rests upon the opposite bars 9, extending through a recess formed in the head of thestandard. his recess is of greater size or length than the width of the cross-piece 15, (see Fig.4) and consequently by turning the set-screw in or out the plow standard is turned on its bolt 1? a; a ivot thereby varying the elevation o t e of the low. The fastenings 11 are located at the front and rear bars of the frame and ow polnt and consequently the tiltconsequently hold the plow beams '99 sesurely at the places where they are set.

The shanks of the colters 16 are each fitted ina casting or block 17 which fits between the bars 9 where it is held by bolts 18. The

shank of the colter extends up through a recess in the block and s fastened by wedges 19 which extendin opposite directions against the o through the block and bear osite ed es of the shank of the colter, at t e ront anc rear; and thewedges are held in place and caused to bind against the shank of the colter by means of nuts 20 screwed on the threaded ends or bolts formed integral with the wedges. It is obvious that this gives a very tlght bind for the colters, but still allowsthem to be readily adjusted by loosening the nuts 20.

The front wheel 8 is carried by a knuckle 21 at the lower rear corner of a frame consisting of front and rear rods 22 and 23 which are connected at the top and bottom by cross bars 24 and 25 respectively. The rod 22 is free to move up and down in a sleeve 26 which is formed integral with the arch 7 and bolted to the front and side bars of the main frame 6. The height of the furrow wheel, or

rather the height of the frame with respect thereto, is adjustedby means of a lever 27,

which is connected to a rock-shaft having a chain-wheel 28 connected by'a chain 29 to a bracket 30 at the top of the bar 22. Obviously by manipulation 'of the lever the furrow side of the frame may vided with a rack engaged by a toothed segment 35, at the end of a lever 36, whereby the rear end of the frame can be raised if and be raised or low when desired. The arm 32 is pivotally mounted upon a stud 37 forming a part of the bracket 38 which is fixed between the rear ends of the bars 9 by a bolt 39, and a.

engaged by the teeth of a segment wheel 46 carried by a stout cross rock-shaft 47 which is provided with a latch lever '48 whereby it may be turned. And when the shaft is turned the land-wheel is raised or lowered accordingly. a

The rock-shaft'47 is uite eavy and in f fact sustains practically a l of t e draft of the machine. It is carried in heavy hangers 49 bolted to the side barsof the main frame 6, and the middle portion thereof is squared to receive a chain wheel 50 to which the draftchain 51 is connected. This chain extends forwardly from the wheel, under the main frame of the machine, at a slight distance above the ground, and it is connected at its front end to a hanger 52 to which the clevis 53 maybe attached at any one of a series of holes 54. The whifiletree orv draft appliances are connected to the clevis as usual.

When the lever 48 is latched the strain or draft through the chain and wheel to the rockshaft 47, and thence to the main frame and consequently to the plow shares. 4 a very low line of draft which makes a steady and easy runnin plow, and avoids any tendency to tip or t' t the implement. Thehanger 52 is fixed to a rock-shaft 55 carriedin brackets at the front end of the beams 9. This rock-shaft has n the end adjacent the furrow wheel a ch in wheel 56 which is connected by a chain 57 to the bracket 30 heretofore referred to. Now, when the draft chain 51 is slacked off by swinging the lever 48 rearwardly, which raises the frame, or at least the land side of the frame, the pull of the draft animals swings the hanger 52 forwardly. This turns the rock-shaft and winds up the chain 57 5 on the wheel 56, the effect of which is to lift the front end of the frame and consequently tilt the plow points up so that theyquickly rout of the ground. This very desirable feature relieves the operator of the labor of 69 lifting the plow shares without assistance of the pull of the team. The lever 27 can then i very easily be thrown forward to catch the frame in its raised position andthereafter support the plow shares in raised position out 5 of the ground.

The rear is communicated from the clevis- This gives and seems The tongue 58 is set on a cross-bar 59 which is supported by brackets at the outer v end of an arm 60 which arm is pivited at 61 to a main bolt at the front of the machine. The bracket to which the tongue is attached has an arm 62 connected to a rod 63 which extends at an angle to connection with the upright rod 23 of the frame which carries the furrow wheel. The rod 63 has a collar 64 in which the rod 23 is free to work. Whenthe 5 tongue is swung laterally as in making a turn the connection between its brackets and the said frame causes said frame to swing and turns the furrow wheel accordingly. The steering arm 60 also has "a lateral arm 65 which is connected by a long rod66 to a bracket 67 on the frame of the rear wheel, so that said wheel is caused to follow the turn, in 'a well known manner.

The rear end of'the steering arm 60 is provided with a collar which extends around the bolt 61,, and in its rear edge said collar has a notch 68 which receives the front end of a latch pin 69, said pin being slidable in ahousing 70 on top of the beams 9 andhaving 2. depending arm 72 which is connected by a chain 73 to an arm 74 projecting from the rock-shaft .47 as clearly shown in Fig. 4. The front end of the latch pin is normally held in engagement in the notch 68 by means of the pressure of a spring 75 coiled around said pin. This revents any turn or swing of the tongue anf keeps the draft in a straight line.

When the plow shares are lifted out for the purpose of making a turn the rock-shaft 47 is turned backwardly as heretofore explained, by movement of the lever 48, and when this is 'done the chain 73 pulls the latch bolt 69 and releases the same from the notch 68, thereby freeing the steering arm so that j the tongue may be swung in either direction,

and accordingly the plow may be turned as desired. As soon as the plows are drop ed into the ground the latch re-engages, an so holds the implement to a straight furrow.

The drawings show a double gang plow, but one plow can readily bere'moved to produce a single plow' by takin off the bars 9 nearest the land wheel and removing thev rear wheel and its fixtures therefrom and attaching the same to the rear end of the short bars 9 which have a bolt hole 39 for the purpose of receiving the bolt 39 by means of which the rear wheel bracket is attached. Of course by varying the size of the main frame it may be made large enough to receive three or more plow shares. Various other modifications may be made within the scope of the invention' What is claimed is- 1. The combination with a wheeled plow frame, of a rock shaft provided with an operatin lever and extending across the frame aving an operative connection with the 1 0 'nection to the land wheel to land wheel to raise or lower the frame, a dratt chain having connection to the shaft constructed to slaclren the chain when the frame is raised and to tighten the same when" lowered, and means actuated by on the slacliened chain to lift of the frame ground.
