and 4. The other arm of each bell-crank lever extends laterally outward and is provided at yits end with a foot-rest 48. It will be obvious that the driver by the pressurepf the foot upen one or the other of the footrests 48 will cause the bell-crank levers to 1ock,"moving`the arm 45 laterally to one side or the other, and thus angling the wheels, as is best shown in Fig, 4. V

By looseniner the bolts by which the forward ends of the brackets 21 are secured to the front frame and the bolts by which the inner ends of the braces 26 are secured to the rear cross-bar 12, and by loosening the cli s 24, the brackets 21 may be moved inwardls) .towards and away from the center ofthe hachine and locked in any desired position, the front and rear bars receiving a number of erforations for the insertion of the bolts. y this means the wheels may be laterally adjusted towards or away from each other to suit different widths.

It will be obviousfrom the above descri tion that by unfastening the bolts by whici the seat-beam is secured to the hounds the seatalso that the wheels may be readilyI removed if desirable, for convenience of shipment or otherwise. v

.lh'e gang frameforcarrying the cultivating appliances is composed of cross-bars 49-50 secured together by cross-bars 51 at 'their outer ends.

52 indicates clamps, whichv are. bolted or otherwise secured to the cross-bars 49-50 in which are adjustably clamped the standards 53 of the cultivating shovels 54 55 in such a way that their position may be varied therein and may be securely clam ed in any desired position by means of bo ts 57. 4i have shown in my machine two kinds of cultivating shovels-434, knownas weerlers, and 55 generally known as duck-feet but, of course, any other kind of shovels or cultivating appliances may be used.

53 indicates draw-bars, whose forward ends are pivotally mounted in the lower bifureated ends of the hangers 15 and whose rear ends are bolted or otherwise secured to the gang frame.

59--60 indicate rock-shafts, one upon each side of the machine, jourmiled in the brackets 27 v 123. 'lhe outer ends of the rockshafts 59-60 are bent at right angles to form arms 3W-60 which extend backwardly substantially horizontally.

61 indicates links,whose upper ends are pivotally connected with the rearward ends of the arms 59--6(), and whose lower ends pass through lugs 62 bolted-or otherwise secured to the draw-lmrs 5S, and are prevented from being lifted out of the lugs b meansof Cotter-pins or other suitable wellnown /device.

63 indicates spiral expansion springs,

-,\vith the segment 76" both levers will' be `lever 65 is bolted or otherwise rigidly secured to the segment 76. ally mounted Aon' the segment 76 by means notched segn'ient 76 and the latch 79 on the whose upper'A end bears against a suitable? 'shoulder on the link 6l and whosc lower` end l bears uponthe. upper surface of the lugs 62,

thefunetion of the s ring being to yieldingly hold' the shovels in t 1e ground.

It will be obvious from the above descripi tionthat if both ,the rock-shafts 5.960 are f rocked the. gang Jframe will be lifted parallel toitself throughout its length, raising or low-v ering all the shovels simultaneously, and that if one. of the rock-shafts only is rockedthe Gang frame will be correspondingly raised or i 'o wered at oneI end, tilting the same so as to i kee itin pro r relation with the ground ref garrlessof t e tilt ot' the carrying frame.

The rck-shafts are rocked by levers 64 65, 'whichare connected, respectively, by links l 6667 and' to downward-depending arms -which are clam pcd or otherwise rigidly secured to a squared or non-circularp ortion at the. inner 'ends of the rockshafts 7] indicates a notched segment, which is bolted to one of the seat-frame barsSB and is provided with a hollow portion 72 in which is seated one end of a sleeve 73, as is bestl shown in Fig. 8. 'lhe other' end of the sleeve 73 is seated in a block 74, which is held in position by the boltinqr together of the parts Hereinafter describe( 76 indicates a notched segment provided with a sleeve or hub portion 76n by means ol' which it isr'otatabl'y mounted on the ,sleeve 73, .the whole being bolted together in 'position between the bars 33 by a bolt 751 'lhe The lever 64 is pivotof a pivot-pin 77. Each ol' the levers i's provided with the usual spring-seated latch 76-79 operated, respectively,-bythe usual hand-levers 80--8land links Q2-83. '[l're latch 78-on the lever 64 engages the lever 65 engages the fixed notched segment 71. It will beobvious from the above descripn tion that if the lever 65 is released from the. fixed segment 71 and the lever' 64 engaged swung together and both rock-shafts will be simultaneously lifted, lifting the gang vframe throughout its entire length parallel to itselt. Ii", however', both hand-levers 86 and 8] are operated to disengage. the latches 7X and 79 the levers 61%65 may be operated so as to rock either ot' the rock-shafts, or one rockshaft in onc direction and the other in the other, correspondingly tilting the gang trame; from its horizontal position, as may be desired. ,',lhc action ol `the. levers in raising and lowering the frames is assisted by the springs X4, which are connected at their forwar'd ends to suitable brackets S5 on the` front bar 12 of tlfc carrying traine and at their rearward ends to brackets S6 which are secured to and project upwardfrom theI arms 59--60 of the rock-sha ts 5504-60, The torward ends ot' the springs 84 are preferably connected to the brackets 85 by means of an eye-bolt S7. the eye of which receives the forward end ot' the coiled springand which may be adjusted so as to vary the tension Iof the spring by means oi' a nut. 8S screwed u on the screw-threadedforward end-of the eyc- )olt 87.
