To all whom it may concern:
Be it known that'I, FRANK LATHROP,
a citizen of the United $tates,and a resident of the city of Dayton, in 'the county of Me itgomery an t t of Q o, a vented certain new and useful. Improvements in Disk Barrows, of which the folowing i a full, lear, and e c s p i reierfence being had to the accompanym drawings, forming a part of this speci cation.'
My invention relates to improvements in disk barrows provided with two. sets or ases of qta y di ks o r a ang d on: n from of th e h an i which the men smut di ks at ach ge e a u ua y turne in op ,n ite ire t-i ns s th t h r a et will le sl fi and the gb P lverise the groun thmw 11% y he f ard s t and the groun thu e n on operst en- Heretofore in such constructions the frames carrying the two gangs of disks have either been rigidl connected together to form a single rigi frame or the frames for the two gang have been separate and merel couple, together in tandem by a 1n the ormer case 1:
corners, wh le in the latter difliculty is ex- I .erienced i e in e two ets of g g ii line while trai er ing the field,
In a li agplic t en Se ial o, .fi' fifie, duly a1 Qwed r ary 3, %1 ha devised a construction to obviate these difllculties in which the main frame to which the g ng ames; e swi elsd, i ormed with flexible side ars whieh, while maint inin s fl i nt rigi ity- EQl' the, Pu pose, mi the main frame to flex laterally unr side s ns in. turning corners! i T e obje of my re nt n en n is t0 PIQYidB side bars for they main frame. pivoted to. the front and rear bars of the frame, o permit e-I me late al y, a d inyhia, h r gid trq t ame -is ma nmm di sprmgs 'ex r ng their influence between, {he side and transverse bars of the main framework.
In the drawings, Figure 1 is a top plan actively treated e r g dity f the si gle frame. p esent di culties tu n ng view of'my improved construction. Fig. 2 is a, central longitudinal section of the same,
The main frame is made up of a pair of parallel angle bars 1, 2', properly bolted together to form the front-bar of the frame, side angle bars 8, 4,'which are loosely pivoted toswing horizontally on vertical bolts 5, 6, to plates 7, 8, bolted tothe front bar. The rear ends ofthese side angle bars 3, 4, are in turn ivoted to swing horizontally by bolts 9, 10, o the flattened ends of the,"rea'r cross barll. In this way, a main frame of rigid members is provided, adapted to swing laterally on vertical pivots at the four corners of the frame. The front pivotal connection on the bolts 5, 6, is made sulficientlyloose to allow vertical play for the These firings are sufliciently powerful to maintain e proper alinement of the gangs and to 1pfeserve the rectangular structure of the ame under the travel of the implement in a straight line, but under side strains permit theiframe to swing laterally.
Securely bolted to the front cross bar at the middle and bracedby the side braces 14, 14, is the tongue 15 of the barrow. Upon each side of this tongue is pivotally mounted a hand lever 16, 17, provided with the usual notched segments 18 and the hand ldsgtihes 19, for lockinig leversl and the 4 s gan m. an eslr an ar 051- tion to th e l'ine of draft. gu P The disk are arranged in two sets, two angs in front and two angs Q, in the rear, one gan of eac set on in? ide Of the ne o raft an e other gen on the other side of the line of draft, am? with the disks or cutters turned in opposite directions so that the rear gangs will throw, the dirt in a, direction opposite. to the'throw of thefrontgangs.
The disks 20 of each gang are strun to- :55 the front gangs are mounted at the lower Lshaft having 'a head 23 atv one end and ang frames suspended and supported om themain frame by a coupling 27 and horizontal bolt so that each gang will swing in a horizontal plane. The inner ends of each of these two front gangs are separately connected by the connecting bars 28 to the lower ends of."their respectiveadjusting I levers 16, 17, whereby upon shifting the" leyer the, proper angle to the line of draft may be given to the gang in the usual way,- Each of the rear gangs is also mounted in aseparate gang frame made up of two parallel bars 29,29, and each gang is sup-' ported-from its gang frame by hangers 3Q 1n wh1ch -thegang shaft is properly journaled.
The gang frames 29 are pivotally secured V to the main frame to swing in ahorizontal plane about midwayof their length by the same bolts 9, 10, which pivotally connect toother the rear cross bar 11 with the side are 3, 4, and the inner ends of these two gangsare held in a horizontal plane and adapted to' be adjusted ,angularl'y to the line'of draft by the. coupling blocks 31, 31. 011s couplmg block is provided for each gang and 1t? consistsof a rectangular loop and an opening 32 of a height to loosely embrace the transverse cross bar 11 of the main frame and to allow free movement back and forth of the loop on thecross bar. Each 5i loo is also pivotally secured to the inner en .of its, respective gang frame bythe pivot pin .33. Each loop 31fis connected by its connecting bar 3 Yto: its respective adjusting lever'lfi, 17, so that the gangs may be properly adjusted at the desired angle .to the line of draft for the varying conditions ,of,soil andrthes'e connecting bars are prefe'rably made in sections coupled together at 35. As the disks of the front gan are setin opposite directions to the disks 0 the rear 0 gang, the desired angular adjustment ofthe ront and rear gangs will be in opposite directions so that the connecting bars 34 for the rear gangs are pivotally mounted to the levers 16,'17,.above the pivots of the'levers to thetongue and the connecting bars-28 for l endsiofthese levers below the tongue. ivots.
lt jwill be evident that when it esired to'use the front harrow alone, therear bar- .eico ectinglbars 34 ile I have illustiateq harffiw provided with rounddisks,flthe ordinary cut disks are also provided, and for many varieties of soil the cut disks are preferable, owing to their spading action.
'The' usuahd'rivers seat 36 is provided, supported by a standard 37 bolted on the rear='end of the, block 38, secured on the avi'n'g thus described my invention, what I-claim as new and desire to secure by Letters Patent is 1. In a disk harrow, the combinationwith front and rear ang frames, of a main frame, to which t e gangframesare pivotally' secured, saidmain frame comprising a front and a rear transverse bar, with slde bars'adapted-to swing in a horizontal plane,
with means for holding the main frame normally rigid, whereby the main frame will swing laterallyunderside strains in turn- 'in'g icorners without affecting the rigidity of the 'main frame during the forward progress of the machine. 4 2. In adiskharrow, the combination with front and rear gang frames, of a main frame, to which. the gang frames are pivotally secured said main frame comprisinga front and a irear transverse bar, with rigid-side barspiv oted to the front bar to swing ina horizontal plane, with means for holding ,the main frame normally rigid, whereby the main frame will swing aterally under side v strains in turning corners with out afiecting' the rigidity of the main frame during the forward pro ressof the machine.
3.. In a disk harrow, t e combination with front and rear gang frames, of a main harrow, to which the gang frames are pivotally sec&1red,'said main frame comprising afront an bars adapted to swing'in a horizontal plane, and springs intermediate the rear portion of the side bars and the rear cross bar, wherebv a rear transverse bar with rigidside the main frame will swinglaterall under side strains in turning corners an at the same time the rigidityv of the main frame during'the forward progress of the machine will-be maintained. p I v 4. In a disk harrow, the comblnation. with front and rear ang frames, of a main frame, to which the gan frames are pivotallyjse'cured, sai'dmam rame comprising a frontand a rear transverse bar, with rigid side barsiadapted to swing in a horizontal plane,floops{mounted loosely on the rear crossbar andpivotalconnection for said loops,withthejinner ends of said rear gang frames, ."withj ad'usti ng'; levers and connecting bars' to 's'ai "loops whereby the rear gang frames-will be held in' horizontal position'and at thefsame; angularly adus d with front and rear gang frames, of a main framework ofindividual rigid members consistin%) of side bars, and front and rear cross ars pivotally secured together at the corners to swing laterally, with springs to maintain the rigidity of the frame under normal conditions.
