To all ufhom 'it may concern:

'Bc it known that I, JuAx'LAsoLois, a citizen of Canada, residing et Moline, in the county of Rock lsltmd and State of Illilmvoinvented nev and useful lm provemcnts in (talig-Flows, of which the following' is a' specification.

This invention relates to gang plows, and it has for its object to produce a riding and `improved construction and which shnll be thoroughly useful and effective in opera-tion.

A- specinl object of the present invention is-to provide a construction whereby. it n rock or similar obstruction shall be encountered bythe plon..tlie nose ot the plow will be ytilted in :in upward direction, causing the. plow to ride over the obstruction Without danger of breakage or injury, .fitter which the parts may be replaced inipcsition 'or operation.

Further objects ot the invention are to provide a, simple and improved construction whereby necessary andv desirable adjustments device may be conveniently effected. A

' ll'vith these and other ends in View which will readily appear as the nature of the inventionis better understood, the same consists ipl the improved consti-notion and novel arrangement and combination of parts which Weill be' hereinafter fully described nd 'particularly pointed out in the claims.

In the accompanying drawings lisis been Villustrated a simple and preferred form ot' the invention, 1t being, however, understood that no limitationis-,nccessaiily mode to the precise structural details-therein exhibited,

ut that changes, alterations end modi-tica;-

Fig. 8 is a perspective detail viewof one of the sector supporting brackets. Fig. 9 is a perspective detail view ci' one of the sectors. Fig. l0 is a perspective detail View of one of the draft slides. v

The axle l supports uprights Q, 2 which nre connected at their upper ends by. a cross bar 3, said uprights and cross our constituting what will be known as the iront treme. The main frame B is composed of side members 4, 4 bolted upon and extending rearwardly from the uprights 2. The side members -l e nre of unequal-length, and said side members are provided nt their rear ends with inwardly extending brackets 5, 5 which are connected together by a longitudinal brace The bracket 5 forms n step or offset. in advance of the rear end ot the fiume where the bracket 5 is located, this construction being adapted to a gang plow composed of two umts. Nhen additional units it' to be employed additional ofsets or brecltets iure to be formed in the :trame structure to accommodate such additional units.

Brackets including vertically disposed sleeves 8 are suitably bolted or otherwise secured upon the ends of the axle, said sleeves affording bearings 'for the shafts 9 provided at their loiver cnds Withspindles l) upon which the transporting Wheels 11 are journnled. The shafts 9 nre vertically slidable in the sleeves 8, and said shafts are provided :it their upper ends with collars l2, each having a notch 13 wherein is iv` oted one end of a link lA, the other en of which isjpivotally connected with one arml cie-s lever l5 ulcrumed on the main frame B and having a stop member 16 engaging n rack segment 17, whereby the parts will be retained in 'adjusted position. it will be obvious that by meons'of 'the adjusting. le-

"rers 15 the transporting -Wlicels may be raised or lowered with respect to the frame, thus enabling one of sold wheels to be usedv as a lend t-vheel and the other ns a furrow Wheel.r While for tri-importation the wheels therewitliyl said shafts or uprights cing extended. through the cross bar 3 of the `front .y frame and provided with nuts 24 whereby they arr.y firmly secured in position. The

forwardlyfextending arms 20 of the plates 19 are pryided with longitudinal slots 25, and adjacent to said slots are upstandmg flanges or .gdes 26 between which the draft slides 27 guided, said slides being provided witl'` bolts 28 extending through the slots and constituting stops to 'limit the movement ef the slides-"27. The slides 27 are also provided with reinforcing. ribs 8O which are transversly apertured for the passage of bolts 3l'.

livotally .mounted on the curved bracket 21 of each plate 22 is a toothed sector 32 having at its front end an anti-friction wheel 33 andzterminating at its rear end in a beak 34.

.Connected with each sector adjacent to the rear end thereof a chain`35 which 'is guided forwardly along the under .arcuate edge of the sector in engagement with the teeth of the latter, said chain being connected atits forward end, preferably by means of an elongated rod or link 3G, with one end of the transverse connecting bol-t 31, whereby the said chain is connected with the 27.`

Slidablyniounted on cach of the shafts or uprights 23 is a sleeve 37 having rearwardly extending arms 38, one of which is provided with a lateral fia-nge 39. The' beam 40 of a plow unit is pivotally secured between the arms 38, and the parts are so arranged and assembled that the anti-fric 'tion wheel 33 at the front end of a sector 32 will normally engage the underside of the flange 39 near the front end kof `the latter. Pivoted on the plow beam 40 is a latch member 41"-having at its lower/end a beveled hook 42 engaging the correspondingly beveled beak 34 at the rear end of a sector Bolted on the beam 40 adjacent to the downturned port-ion which' forms the plow carrying standard 43 is a rearwardly extending .arm or bracket 44 having a Tl1ead 45. The plow beam also supports a block 46 carrying an adjustable hook bolt 47 which is connected by a strong helical spring 48 with a hook 49 pivotally associated with the'latch Y vented. Bolted member 41, said hook member being mounted on the latch member intermediate its fulcrum and the upper end thereof which is connected by a link 50 with en adjusting lever 51.'.I

' It will be seen from the foregoing descrip .tion that when the parts are assembled for operation, the beak 340i the sector 32 engages the h ook 42 of the latch member 414V the contacting faces of the beak and the hook being slightl beveled, as shown, to enable the beak to become disengaged from the hook by the exertion of a predetermined degree of tension which may be governed by regulating the tension of the spring 48 by means of the adjustable hook bolt 42. The spring 48 must be sucientlv strong to resist the ordinary strain of, plowl Should this strain become greatly exceed as when an obstruction is encountered, the beak of the sector will become disengaged from the hook, and the sector will turn aboutl its axis,l causing the anti-friction wheel 33 to exert upward pressure against the' flange 39, thereby tilting the front end of the plow beam, together `with the sleeve 37 in -an upward direction, and throwing the nose or point of the plow unity in an upward direction, causing it to leave the ground until the obstruction has been safely passed, after which the Aspring 48 by the use of theadjusting lever 51, may be again placed under tension, thus enabling the beak of the sector tobe again placed in engagement with the hook 42. The draft is applied to the slides 27 by mea-ns of a. connectingbar 52 having means such as a clip 53 for the attachment of the draft.

The bracket membersl 5, 5 at the rear end of the main frame are each provided with lugs 54 between which and the T-head 45 of the rearwardly ext-ending arm 44 of one of the plow beams 40 is guided in such a manner as to permit vertical'movement to take place while lateral movement is preor secured on the rear sides of the brackets 5, 5 are segment racks 55 upon which hand levers 56 are fulcrumed each of said levers being provided at its lower end with a forwardly extending arm 57 having a laterally extending supporting hook 58. Pivoted on the fulcrum of each of the levers 56 is a rod 59 which is loosely supported ou one of the supporting hooks 58, the front end of such rod being connected b v a link 60 with .the T-head 45 of one of the arms 'or brackets 44 extending iarwardly from the plow beams. Each of t e hand levers 56 has a stop member 61 engaging the segment rack 55 for the purpose of retaining the parts in adjusted position. It will be `seen that this construction not only enables the plow 'units to be independently raised or lowered for the purpose of f are peee to engage the. 'lower 'ef manpnating the' same.
