To all whom it may concern: "".Be it known that I', l-l'ENRY MGLAREN, a" subject. fof the King of Greatv Britain and Ireland, of Midlandv Engine XVOrks, Leeds,

inthe county of York,ICngland, have in-' ,raising the plows' from the soil and holding themA in that position and for lowering tlieni to their work and regulating their depth of wrak, and for raising and lowering the subsoilers, in plows in which subsoilers are used, and providing other*improvements as hereinafter explained.

It. is necessary for the plows and subsoilei's to be lifted out of the vsoil at. the ends of the fui-rows to admit of the engine -and plows turning around and to 'reenter the ground on the return vjourney. Hitherto this lifting has .been usually done by levers operated by hand, which necessitates heavy manual labor and loss of time, and, in the ease of `heavy plows, for deep work, it is impossible to lift ina'ny plow heads at one' tinie. Meehanieal liftsI operated by strain, and otliei-,power have been used and worked from the engine, but. they are costly and gcoiiiplicated and not suitable for operation by the unskilled laborer usuallyk in charge of plows. l

Aer-ordine' to iny invention the l plows' (and subsoilers when used) are iliade lseltlifting, the-attendant when it is desired to lift. tlieiii, siinply throwing over a -tinnbling lever which brings all the plows (and lsub- 'soilers when used) to the .surl'aee without .50"ivention is not liinited to that innnbeif'- 'lf further-manual labor, .so that one attendant .can operate a large number ol plows, or plows' and subsoilers, `without delay or stoppage,ot the engine.`

Figures l and 2 are an elevation and a ,Y

plan respectively of a four-furrow p10\v (without subsoilers) constructed aocordingl to this invention; Fig. 3 is a plan showing a series of three sets of plows connected to-v .getliei and to the-engine; Figs. 4 and 5 show, in elevation and plan respectively, the means for retaining the plows in their raised'position, and for adjusting the inter. mediate wheel; Fig. 6 is an elevation show-r ing the arrangement of the subsoilersin a i plow; Fig. 7 shows in elevation the means.

for raising andlowering the subsoilers.-A

The plow# l are carried on a :traine 2I supported by three wheels, the forwardwheel 3 traveling inthe furrow left by the last plow `on the Yprevious round, the hinder wheel l runningi inthe furrow left ,by the last plow of the series, and the intermediate wheel 5 ruiming on the surfa'eeof the iinplowed land. The forward and hinder wheels 3y and 4 are eaeli inounted (man in.-

elined arni (i at the lower end of 'a vertieal spindle 7. as .shown` in Fig. 3,-and eae-h of the said wheels'is :id iustable vertically, so that,

when the plows are not .in aetion, but are travelingontheroad,the saidwheels are set;

lower than the bottoni eutting .edges of the plow lshares and keep thein elear of the road, but when plowing, the underside (if-each of these wheels' runs approximately level 'witln The the eutting edges of the ploiif'fshare-s.

'said arins ('r are ineliiied downward so as vito throw the said wheels 3 and 4' ont' of the perpendicular and bring the lower portions ol' their suitably inclined rims into the corner of the furrow, as shown in Fig. 3, to...

u.' al nian'ner.

'l`he 'forward wheel l should be provided wi.li greater vertical adjustment thantlie take the side thrust of the plows in the hinder wheel Jl. `it being` necessary for the.-

forward 'wheel to tiavelontlie surface of the- .ei'ounil when 'starting on new land where there is'no f previous fui'i'own The forward wheel 3 is :steered by inea'iisl of a lever S'. sevured to the top ot' the vei'tieal frame 2. The verticalr adjustment of the forward wheel 3 is effected by means of a screw (not shown) on the upper end of the vertical spindle 7, and a screw-nut confined` 5 in a pocket 15, cast in the spindle bracket 16, carried by the frame 2, so as tov be rotatable therein, and is operated by any suitable device, such, for example, as a spur pinion '17 (see Fig. l) on a spindle 18, carried in bearings projecting from the bracket 16 and provided with a handle 19. This provides a satisfactory and direct 'method of carrying the front end of the plow on the vertical` spindle 7 The steering hand lever 9 is onlyl necessaryV when .working a single set of plows, or on the first of a series of sets of plows. It enables the' attendant to vsteer the plow, or plows, around the headland and bring the forward ,wheel 3 intok the return '20 furrow should the engine be out of line. When the firstplow is properly entered in the furrow, the steering hand lever 9 is xed by the catch 11, and catch plates 12. Each of the following sets of plows is automatically steered by the preceding set of plows,

and will enter 4the respective furrow withoutv further. attention from the attendant.

The vcoupling of the sets of plows tothe engine and to each other can be effected as 3o illustrated in Fig. 3 as applied to three sets of plows in series. The first Whittle-tree 25 isattached, at" its inner end, to the dragplate 26 of the first set of plows; the second whiftle'tree 27 is attached in the same man-` ner to the second set of plows, the outer en'd of the first Whittle-tree 25 being coupled, by a steel rope, or the like, 28, to the center of the second whiilletree 27, which, inv turn, is coupled from its outer end, by steel rope, or

4`0 the-like. 28, tothe drag-plate 26 of the next set of plows. and so on if more setsof plows be used. The engine (part of which is seen at 29) is coupled lto the first whillle-tree 25 at a point giving thefproper leverage to obtain an equal pull on all the sets of plows of the series.

The frames of the sets of plows are hinged together by hinge links 30 which `keep the sets of plows properly spaced from each other under all conditions of workingl When a set of plows is lifted from its work, the pulll becomes slight, and .it would irnmediatcly overrun the other set, or sets, of plows to the limit of the Whittle-trees it' not prevented by the link 30. which is arranged to allow either plow to lift without disturbing the other'` or others. This can be arranged as i'ollowsrwAV horizontal pivot 31 is fixed to the frame of the leading set of plows. One end of the hinge link 30 is hung tothis pivot 3l, the other cud of the said hinge link being coupled, hy the vertical pin 24, to the frame of the following set ol plows. The hinge link 30 is held sidewise andplateral movement prevented by guide set of plows, while the following set of plows can turn on the pin 24, and the hinge link 30 has ample vertical play to allow4 4either set of p ows to rise, or fall. By this coupling it is impossible for the sets of plows to overrun, orget locked, when turning-corners, and practically the whole vpull ofthe plows is taken by 'the coupling ropes 28, or the like. The said vertical pin 24 has a considerable amount of play in the eye at the end of the hinge link 30, which is some- Ltimes in tension and at other times in coma pression.

The lifting4 gear consists of a tumbling lever 33 (sevgFigs. 1, 2 and 7 secured by bolts to or L, sha ed head 34, on` a shaft 35, carried by brac ets 36, secured to the plow- 'frame 2. The other end of the said tumbling lever 33 is provided with a shoe 37, slotted for the lever 33 to ass through` it, thevslot 3S being lon enoug to allow the shoe 37 to swing free y on a pin 39 which passes through the lever 33, and the carrier of the'shoe 37. The shoe 37 is provided with projections, such as "cross angle-irons 40, to dig into, or grip,. the ground. The effective len -h of the said tumbling lever 33 can be al ered by passing the bolts which secure it to the head'344 through different holes of a series provided for this purpose. The length of the said lever 33 determines the height to which the frame 2 is lifted.v lVhen vthe plows are -at work, thefsaid lever'33 is supported clear yof theground, `for instance by resting on a hinged catch 41 (Figs. 1` and 2). W'h the plows are to be lifted, the tumbling ever is thrown .over (in the direction of the arrow inFig. 1) and the shoe 37 comes onto the ground, and, as the plow advances, the. lever 33 turns o n the center 39 and'describes au' are of a circle and lifts theA plow frame, provisionbeing made for retaining it near Vits highest point which can be effected by the arrangement shown in Figs. 4 and 5. The lifting of thefront end of the frame is done by the front wheel 3 running up the slo e atthe end of the furrow and bringing tlie front plow-shares to the surface (see Fig, 1.) and the front plow cannot reenter the `ground again unless this wheel drops into another furrow, or is altered vertically by the screw and nut.

Referring toA Figs. 4 and 5, the aforesaid intermediate wheel 5 runs on a, crank-pin 42, carricdby a crank-arm and toothed sec- "tor 43, free to turn on a stud 44, fixed to the frame 2.

Then the frame 2 is lifted by the tuinblinglever 33, the intermediate wheel 5 remains on the ground and the crank-arm andsector 43 turn on the stud 44, and the ratchet-teeth of the sector 43 pass a pawl-eatch 45on a' hand lever 46, but when the :frame 2 tends to fall, the sector. isi-held by tl-heisaidpawl-ic'atch 45l i engagingwith the ratchet-teeth ofthe sector 43. The said intermediate wheel 5 isthe only one manipulated when lifting, or lowering, the plows in ordinary work; it also regulates the depth ofthe work.

When'the'forward wheel 3 arrives at the end of the furrow (see Fig. 1) it runs out to the surface and brings up the front plows with it. The hinder wheel 4 is principally a side-thrust wheel when plowing, but it servesas a carrying-wheel when the plow is on the road in the same manner as the The intermediate wheel 5 ispreferably placed somewhat neaierthe back than the-front end of the low, and lit is thisy intermediate wheel 5 w ich carriesA Athe backend vof the plow lframe and regulat-es the depth of the plowing. It is therefore necessary for this wheel to have some adjusting arrangement which may be illustrated in Figs. 4 and `A worinftootlied quadrant, or wheel, 47 provi-ded with an' arin 48 is mounted so' as to be free to turn on theV stud 44,;wh1ch carries the aforesaid crank and sector 43, and the worni teeth engage with a worin 49 carried by a spindlei 50, turning Ain bearings 52, carried by the sector 43, and,

quadrant, or wheel, 47. weight of the traine llf it be4 dcsired'to alter the depth, done by turning the worin spindle 50 so asv fi'ame and provided witha handle 51. 'llie said worm-tootlied qiiadrant., or wheel47 is placed immediately alongside the crank being on the same stud 44, is concentric with it. 'llie ,tail end of the crank pin 42 extends beyond the crank 43, und below the arin 48 on thev worm-toothed lVhen plowing, the 2 supported by' the aforesaid"nterniediate wheel 5, is carried by thequadrant :Win48 resting on the crank-` pin 42, and the depth lis adjusted by turning this arni 4Siip, or down, by n'ieans of the worin 4J'aiid quadra nt, o r wheel, 47. `Wlicu the frame 2 is lifted, theariii 48 lifts with the traine and leaves the crank pin 42, but when the plow is again lowered to its work, the arui 4Sy comes to rest against the crank pin 42 at exactly the saine depth as before. this is to alter the position of the ariii 4S. lVlieii the plow is on the road, tlie traine is carried on the said intermediate wheel 5 through the, sector 48 and l'iawl-catch 45. 'l`o"put the plow to work, the attendant operates the lever 4G' ot' the pawl-catcli 45 so as to release the, vsaid intermediate wheel 5 and allow tlie plows to enter the ground till the arin 4S comes to rest again on the crank pin 42.

lVlieii subsoilers are employed in plows of this type, it. is diHcult to lift the said` subsoilers clear ot theY ground, for, as already stated, tlie. iliider sides of the aforesaid forward and liinderwhcels 3 and 4 run approximately level with the plow-shares 1 item25.?. Y,

when plowing,

are not altered -when vthe ,plow arrives at the end -of thel furrow, the plow-shares l just scrape the surface of the ground when the plow is on the headland, and, kas the subsoil tines `extend a considerable depth below the plow-shares (see Fig. (3),l rovision must be made for lift-ing them. lifeferring now to Fig. 6, the forward subsoil tine 53 is ycarried by a bracket 54 direct from the frame 2 and the other tines are carried by brackets 55 secured to the respective plowheads 1. There is 'no subsoiler immediately behind the rearplow-head, as it is desirable that. the aforesaid forward and hinder wheels 3 and 4- should` travel on solid ground. r1 he subsoiling of this furrow is therefore left until the following round,

when `the first siibsoil tine 53 subsoils this furrow leftby the last plow after the forward and hinder wheels 3 and 4 have passed over ontirin ground.

The lifting of the subsoil tines is effected as follows by they aforesaid ltumbler lever 33,l which lifts the plows. Each Atine 53 hasteeth on one edge of its `upper part56, with which teeth engages a pinion 57- earlried on a spindle 58, passing through bearings in the bracket (54 or 55) and carrying a lever (30 keyed to it. The tine 55E-is held to the bracket (54 or .55) bylugs 61 (cast on the bracket) and straps (i2, but is free to rise and fall. 'lhe straps (i2-arey secured, by bolts (53, to the bracket (54"or`55) and lugs Gl. These bolts ($3 at theback of the tine carry rollers (34, which take the pressure on thetiiie 53 when subsoiling, and less power is required to lift the tines than would be required if they passed through ordinary slots. The several tine-lifting levers (it) are connected together by a 'coupliiig. rod (i5 (see Figs. 6`aud ,7), which is connected by a Apin (iti to a sector 67, which turns on a pin (i8 and has a tappet arm (S9, which projects toward. the vaforesaid tunibliiig lever shaft 35, the sector (i7 being provided with iiotclies 7() and 71 ,to receive a catch 72,on a hand lever 73. of the tumbling lever 33 has a cani 74 (see Fig. 7) keyed to it and also a lever 75 which carries a roller 76. The 44`tumbling lever shaft 35, as it is vturned by the tumbling lever 33, bringsthe said'eain 74 into Contact with a plate 7,7, raises the catch-lever 73, and removes the catch 72 out of the notch 7() in the sector ($7, and, .iiiiiiiediately after i .76 strikes (3*.) on the sector 67 and turns i these Wheelsf and 4,

The shaft 35 VWtines 53, lifts all the tines clear of .the`

und and they are held in this position gfothe catch 72 engaging the notch 71 1n the sector 67. When it is required to lower the tines 53 into the ground, the catch lever 73 is lifted by hand and the tines 53 drop to the surface of t-he ground and are drawn into Work. If the ground be hard, the fat# "tendant, to make the tines 53 enter the ground, can Operate a lever 78 carried on` an extension of one of the levers 60, which i lever isV connected to the fcoupling rod 65. Each tine 53 can be provided with stop pins 794 (see Fig. 9) which can be shifted up. or down, in holes 80 in the tines53 and rest on the li1g61 and strap 62 carried On'the bracket ground with the weight (54 or 55) `to regulate the Idepth Of the subsoiling. -As it takes considerable power to lift the subsoiler, the aforesaid roller 7 6 is arranged so that it does not come into contact with the tap ct arm 69 of the liftin sector 67 untilt e shoe 37 of the tumbllng lever 33 hasl got -a ood hold of the o the plow on the top of the lever. l

Having now particularly described and` ascertained the nature of my said invention and in what manner the same 1s to be pei'- formed, I declare that what I claim is" 1.` A plow having a frame, a surface wheel' with cranked spindle pivotally supported f from Ithe frame, a stop limiting the upward travel of said crank and means for-vertically adjustingsaid stop, for the purpose specified. y
