I' My invention relates generally to machines for spreading fertilizer; sowing seed and the like, and, more specifically, to T'mobile adjustable mounting means for machines of this type.
i Heretofore; it has been the practice in farming to prepare the soil for seeding by harrowing and the like; after whi ohfertilizer may be spread ov r the field, work edinto the soil, and; the field seeded, these separate'operations each requiring a different transversing of theiieldwith aresultant excessive consumption of time. Theprimary object of my invention, therefore, is the provision of a broadcast spreading device which maybe coupled to a tractor or other pulling device, and whichwill .cOoperate with soil-working equipment to .spread fertilizer sowseed while the soil is being ,worked hythe soilconditioning apparatus inflajs'ingle, passage over the'field.
I t Another. highly important object or my inven tion thevprovision of means adapted "to straddle soil-conditioning equipment, such as cultivators, harrows, soillpi lveriz ers, and the .like, ...and:in.- dependently support a broadcast spreader there-k over. for. movements simultaneous therewith but acting independently thereof.
I another object of myqinventionisth: provision ofva n ounting frame for .iertilizer spreaders and the like; which is quickly and easily adjuste able to supporta fertilizer spreader in overlying relationship to soil-conditioning equipment or inclosely spaced relationship to the ground for use withoutother equipment.
,Another object r, myinve-ntion is the pro vision .of a wheel-mountedy device abovedescribed having -a rotary agitator which may be driven-from the supportingwheels thereof in any desiredelevation of the machine.
A still further objecteof my invention is the provision .of a machine of the type abovedescribed having a rotary agitator which may be quicklyancl easily engaged or disengagedfrom' driving connection with: the supporting jwheels thereof for material spreading or fortransport, as desired? is Still another=object of my invention is the provision of a machine which is relatively inexpensive, efficient in "operation, rugged in construction, and durable inuse.

Bearing I1" is identical to bearings I 1 and ,ll fand, together with the flange-equipped trunnion 64, is rigidly secured to the intermediate portion of the base fnemb'er 59 by niited'liipped bolts and 61. It wnr be observed, by reference to Fig; 4, that the wheel hub 63 is'proi ided at itsinner end with acircum'ferential flange '68 abutting the outer surface of'the flange 66-of the trunnion 64. A pair of retaining plates 69 limit axial movements of the wheel' 62 with respect to the "trunnion'64. "It'-'will' be seemby reference to Figs. 3 and 4, that the bolts 61 extend through the retaining plates 69 as well as the flanges 63 and 34'. It is important to note' that the tubular trunnion Stand-the bearingil" of each supporting frame 4 are inaxial alignment.

'3 and 4). The chain 16 is preferably'made up of links '11 that are quickly and easily detached, whereby the chain may be lengthened or shortened without the use of tools, for a purpose which will hereinafter become apparent.
The hubs 63, trunnions 64, and drive shaftsilfl are substantially of the same construction as that-disclosed in my copending application filed May 21, 1949, Serial No. 94,651, and entitled Axle Construction for Fertilizer Spreaders. Each driving shaft is provided with radially outwardly-opening recesses 18 disposed between the shoulders 13 and alignable with a locking pin 19. Looking pin 19 is mounted for axial movements radially of the shaft 10 through the hub 53 and a bearing plate 89 carried by a bracket -B'l integrally formed with theiwheel hub '63. A coil compression spring 82 has one end seated against the bearing plate 80 and its other end working against a washer-equipped pin 93 in the locking pin 19, whereby to bias the locking pin in a radia'llyinward direction. A three-position handleequipped cam 84 is pivotally secured to the upper end of locking pin i9 with its camming surfaces engaging the bearing plate 80' against bias of thespring 82. In one position of the cam 84, the locking .pin 19 is moved to its radially innermost position where it is .seated within one of the recessess 18. In this position, the drivershaftlll islocked to the hub 63 of .its cooperating drive wheel 62, whereby rotation of the wheel 62 'will cause rotation of the agitators 8 and Min the dispensing'unitsi and 2. Movement of the cam 84, to a'second position will move the inner end of the locking pin is out of engagement with the recess H3 but will maintain the same in a posi tion to be engaged by the annular shoulders 73 of" the flanges 72." In this position of the locking pin '19, the wheel ears rotatable independently of its cooperating drive shaft TB. It might here be stated that the above-mentioned first position of cam 84 is illustrated in Figs. 3 and 4, with'fa surface 95 of the cam engaging the bearing plate 80. ':'When the camis moved to the above-mentioned second position thereof, a surface 86 on the cam 84 engages the bearing plate 80; Cam 84 is also movable to a third position wherein a cam surface 8'! lies against the bearing plate 80-. In this position, the locking pin 19 is withdrawn radially outwardly-from between the annular shoulders 13 permittin axial withdrawal of the drive-shaft it from the bearings l1", provided, however, that the sprocket wheel" is removed from the shaft 29. Y
'yAs show'n', the bars :36 each engageoneside of the legs 65 of one of the supporting frames 4. Each of the clamping bars 45 has welded to the opposite end portions thereof clamping plates lid which engage the side of the legs 60 opposite the cooperating bar 36. A pair of clamping screws 89 connect the outer end of one'ofgthe clamping plates 88 to the vertical frame member All, and a similar pair of clamping screws 89 connect the outer end of the opposite clamping plate to the rear vertical frame member 4!. The screws 89 are provided at their inner ends with clamping nuts 98 which may be tightened to frictionally lock the legs 60 between one of the bars 36 and cooperating clamping plates 88. Referring to Figs. 3 and 5, it will be seen that the clamping bar 45, preferably made from angle iron or the like, engages adjacent edges of the channel shaped legs 69 andthat'theclampinggscrews 89 he closely adjacent opposite-faces ofthe legs bynut-e uipped clamping screws 92.
Axial movement of the rotary shafts 22 outw'ardly of their respective hoppers is limited by engagement of their outer ends with stop=plates 93. The outer ends of the shafts '22 areprovided with hearing bosses or-the like 94 that bear against the lower end portions of the plates 93 to minimize friction thereagainst. Each of the .plates 93 is pivotally secured adjacent its upper end to its cooperating clamping bar, by means of a bolt'95 equipped with a wing nut 96. A lug 91., Welded or otherwise-:rigidly :secured to :each of the plates 93, engages the lower surface-of the clamping. bar 45 to'izprevent lateral: swinging movements ofthe plate' 93fi.when the wing nut 964s tightened upon'the bolt 95.;yEaoh wing nut 951 may be loosened sufficiently, to permit its cooperating plate-'93 toz'bemoved axiallyoutwa'rdly to a point where itsf cooperating "lug; will be po; sitioned outwardly of'the clamping bar 45, The
the bottom of thahoppe'r. r v
Loosening the severaliclaniping plates. 88 and 9 I from clamping engagementwith the. legs 69 will permit raising and lowering of "the hopper mounting frame 3 and the hopperscar'ried thereby with respect to the ground. In the drawings;
the. hopper-mounting frame his shown as being located intermediate the high=and--low extreme positions. Obviously, raising or lowering of the hoppereframe '3 '-causes"= a variation. in the dis tance between the. sprocket whels -35' and the driving sprocket wheel 74'. 'For this'reason, Iuse a driving chainlfi having links that are readily removable and insertable. When it'is desired to utilize the machine for merely'spreadin'g fertilizer and/orsowing seed, the hopper mounting frame 3 .willpof course, lie-moved downwardly-to azpoint close. to the bottom'of th'e 'suppor't'i'fig frames 4. "However, wh en; it is desired to use the machine simultaneously with bther a gricultiir'al equipment, the hopper-mounting? frame '3" "is raised to a height suf icient-to permit position ing of said other'equip'ment beneath the "hop pers and between the supporting wheels 22. In other words, my device is made to straddle the cooperating agricultural equipment. Fig. 1 illustrates the ability of my novel device to straddle a conventional rotary tiller or soil pulverizer.
The rotary pulverizer comprises a generally rectangular frame 98 having journalled for rotation therein a double row of rotary tiller elements iii-discs '99. A drawbar llln'is' pivctallypsecured at its rearend to the'frame 98 and is reinforced by a pair of diagonal braces' I! rigidly secured at their front ends to the intermediate portion of the drawbar I00 and at their rear ends pivotally secured to opposite end portions of the frame 98. The drawbars 24 and 100 may be independently coupled to a tractor or the'like. However, I have'found it convenient to provide a vertically-disposed bracket I02 which terminates in a rearwardly-extending tongue I03 which may be connected in a conventional manner to the fork 25 of the drawbar 24, such as by'a coupling pin I04. One leg of the bracket I02 is connected at its lower end to one arm of a bifurcated coupling yoke I05 welded to the forward 'end of the drawbar I 00. a During a single passage of the combined equipinent above-described through afield, fertilizer may be dispensed or spread over the ground from the unit I in front of the forward row of discs or rollers 99, where it is worked into the ground by the front row of rollers 99. Seeds may be sown from the rear unit 2 between the rows of rollers 99 and covered by the action of the rear row of rollers. Thus, a number of operations are performed during a. single passage of the equipment across a field; and a considerable savings in time isachieved. It will be understood that other soil-working equipment maybe substituted for the pulverizer illustrated, such as disc harrows, toothed harrows, and cultivators and the like. Itwill also be appreciated that the machine will work just as effectively with a single hopper as with two hoppers by merely uncoupling the chain from one of the sprockets 35 and connecting'it between the desired sprocket 35 and the driving sprocket wheel 14. Obviously, when one hopper is used, the chain must be shortened to an efficient operating length. It will further be understood that, if the hoppers are divided into double chambers both having axially-aligned agitators as disclosed in my prior Patent No. 2,350,107, one eachof the aligned agitators will be driven from one of the wheels 62, the other of each being driven from the other of said wheels62. However, in the event that a single agitator is used in each of the hoppers 5 and II, the agitators thereof will be driven from one driving wheel 62 only. -My invention has been thoroughly tested and found to be adequate for the accomplishment of the objectives set forth; and, while I have illustrated and described a commercial embodiment thereof, it will be understood that the same is capable of modification without departure from the spirit and scope of the invention as defined in the claims.
What I claim is: a 1. In a device of the class described, a hopper frame, a pair of elongated'hoppers rigidly secured to said frame in side-by-side relationship, a pair of horizontally-spaced vertically-extended supporting'frame members, means mounting said hopper frame between said supporting frame members for vertical sliding movements, rotary agitators within each of said hoppers, ground .wheels on the lower ends of said supporting frame members, and adjustable drive connections be tween said agitators and one of said ground wheels, said means for mounting said hopper frame to said supporting frame members including opposed clamping members carried by said hopper frame adapted to frictionally engage said supporting frame members whereby to maintain said hoppers in adjusted set positions.
2. The structure defined in claim 1 in which said. supporting frame members include horizontally-disposed base members and opposed channel shaped laterally spaced legs, said mounting wheels being securedone each to one of said base members and said clamping members exerting clamping pressure upon opposite side portions of said legs.
3. In a device of the class described, a hopper frame, a pair of elongated hoppers rigidly secured to said frame in side-by-side relationship, a pair of horizontally-spaced vertically-extended supporting frame members, means mounting said hopper frame between said supporting frame members for vertical sliding movements toward and from the ground, rotary agitators within each of said hoppers, said agitators operatively terminating in rotary stub shafts which project outwardly from adjacent ends of said hoppers in spaced parallel relationship, drive wheelssecured to the lower endsof each of'said supporting frame members, and adjustable drive connections between said stub shafts and said drive wheels, said supporting frame members includinga pair of laterally-spaced. upstanding legs, said means for mounting said hopper frame to said supporting frame members including a horizontally-disposed hopper frame member spanning said legs at oneside thereof, a clamping bar spanning said legs at the opposite sides thereof, and clamping screw means connecting said clamping bar with said hopper frame member whereby to maintain saidhoppers in adjusted set positions, and stop means on said clamping bar preventing axial movements of said stub shafts in one direction. -41-The structure defined in claim 3 in which said step means comprises a pair 'of stop plates removably securedto'said clamping bar and p0 sitioned thereon to engage the outer ends of said stub shafts, removal of said stop plates permitting axially outward movement of said stub shafts irrespective of the position of the hopper frame with respect to the supporting frame members.
