To all whom it may concern: 'l

, Be it known that I,DUDLE Y Gmzs'r, a citizen of the United States of America, residing at Waterloo, in the county of Blackhawkand lState of Iowa, have invented certain new and useful Improvements in Straw-Spreaders, of which the following is a specification,

reference being had therein' t0. the, aqompnyngdrawings,

lo In the operatlon of-stravv spre'adersit is.

desirable that the load'be evenly distributed I under all conditions of service and that there i be uniform operation of the device.k Whether there bei a full or partlo'ad therein so that. the amount deliveredI is .the same at beginning of the take ofof. the loadasit is at the :last end.' It .is alsodesirablet Vadjust the feedingv devices vto meetLNariOU. conditions of the material 'handled as well as those v n' ableprop'ortioning of the cross members;6

under which the machine is working.

This mvention relates to a 'straw spreaderl wherein provislon is' made for preventing even feeding conditions uponth'eload and for maintaining a constant delivery thatis y i entirely independent of the amount of strawf in the machine.

' The invention also includes a. rack con-- struction whereby capacity and width are secured and the rackmade applicable yto a" running gear of narrow tread; and` further-l to means for regulating feeding and tensioning -vdevices and for other adjustments that Yare advisable in this type of machine. c In the drawings, Figure 1 is a view in sideelevation of a straw spreader that embodies features of the invention; Fig. 2.is a view in elevation of the opposite side of the machine; Fig.l 3 is a view in rear elevation vof 4o the'ma'chine;'Fig. 4 is a plan view of a part of the machine with parts removed to pre- L vent confusion; Fig. 5 ,is a plan view of a vportion of the machine body with adjusting driving mechanism and jchain wheel guards;

'.2? l preferably to th'el-fi'ear'fo'fthe traction driv ing'wheels 2 and apa-ir of main driving, sprockets 18- 'are mounted on thetraction 975 Wheels 2. In preferred vform these sprockets i are annular with carrying bolts 19 supporting them on the wheel spokes 20, oppositely disposed check nu ts`21 (Fig. 7) permitting lateraladjustment.

a throv1 out pinion 2 5 located at the forward 105 side'of its sprocket 18, ."Ihe sprockets 22 are eah'connected by suitable differential mechanisms to the shaft 17,which comprises, as shown in Figs. 8 and 9, a disk 2G made fast rota-table. Aiswinging-vdogf28carried-bythe disk engages projections 29 on the sleeve I a ,spring 30 being provided to hold the dog in4 engagement therewith and cause the sprocket and'shaft to turn together in onedirection. A rock shaft 31 is mounted across the sills t the forward sideof the traction wheels 2, preferably in bearings that are` justable longitudinally of. the sillsalndcolistructed as shown, in Fig'. 10 with-'an under:

block 32, a cap33 and holding4 bolts 34 that pass through longitudinal slots 35- in the' superposed parts.

A rock arm 36 on the rock shaft, is operated by a throw-in lever 37 which is adjacent thel drivers station, and' 4.is preferably connected to the rock arm,byf i.p `a longitudinally yieldable connectionatlz'ord-f ed by a rod 38 that passes through a fork 3 9 pivotally attached to the arm and through it spring 40 thatis in compression between the fork base and a suitable late-or keeper ,41.onthe end of the rod. y en inl forward position the lever 37 interlocks with a latch at the rear of the traction wheels and. can rying at their freee!1dsio1ers 47 to engage ,f the lower runSMo-fhthechains 23 when the lever 37gisswung forwardly to swing they sprockets' 25lip'wardly and 'raise the chain out of contact `sritli'iahe driving sprockets' 18.

The swinging idlers 47 also seri-'cto take up the slack in the chains.y

Acarrier drive shaft 93`extend1ng across the-rear 4endoithe machine has driving sprockets 48 disposed in pairs thereon to envgage s' rocket chains 50 forming side members o? endless conveyers each comprising a pairof said chainsand cross bars 53 These carrier chains pass forwardly over a suitable'bottom or floor 'for .the rack and around idler sprockets' 51 on.- shafts 52 -at the front end oi the machine, there being a separate shaftl 52 for each carrier to provide for differences in the chains.' The-cross members 53 of one carrier are preferably .arranged in staggered relation'to those of the otherv carriers to more evenly engage the load and' lessen the drag on the door. There 'is-a' great advantage in the construction in longitudinal sills 5 for supporting the rack.l are employed, as these sills rest di rectly upon' the holsters and -supporting the crossmembers which su port the floor and i extendA the-full width o the rack with the sides Of-fthe rackJ secured directly thereto.

Such.v sills interfere with the use of va -V single endless" carrier but by providing a4 plurality of" independent carriers to travel :in the spaces between the sills and between each sill'- and the rack side, a light, 'cheap and rigid-construction isl secured. 'lo preyvent the4 outer carriers y.from striking the guards 94 may be y ao J'Lx/Yarialble intermittent motion from front ,tractionwheela Wheel rovided ,if necessary.- f.

to :rear is given-'to the endless conveyers by means of a ratchet 4wheel 52 on one end of thumairifshaft, operated by a pawl 53 `*pivoted 'onl an'farm54 that is pivot'ally at-' ltached at one end to the rack side by a-stud 55 or the like.

A crank disk 56 on a counter shaft 57' driven 'by suitable sprocket and chain connections, indicated generally at 58 l(Fig. 2,) from` the main shaft 17, has a crank pin-59-that is coupled to the lever 54 by a link 60,` Variable stroke is given to the lever 54 by'ashiftable adjustment of the pin 59 which i yinou'nted'on an arm 61 pivoted at' one endsto the'disk 56` and adjustably secured at its opposite end to the plate by a clamping screw 62 movable in acurved -slot '163.A in vthe disk so that by swing-A ingthe arm the crank'pin may be vmoved 'toward or from the a-Xis of rotation of the disk... The link may also be shiftedon the barl 54 with which -it has a sliding block connection indicated at 65, said block being' shiftedlongitudinally by means of a hand lever 66 connected to the block by rods 67 and 68.' A dog 69 'engaging the ratchet wheell 52 'prevents' retrograde r movement of 'the'parts This arrangement gives anmesired throw,l and providesY the preferred iris termittent movement. v

A beaterI drum 70 is secured on the shaft 57 and is 'provided with lingers 71th`at are f preferably olrliquely disposed as indicated.

A companion'drum 72 with vsimilarly "disf posed fingers 73 is journaled -in spaced rela- ;tion above the shaft 57 on the rear rack astanchionsand is operated from `said'shaft by sprockets 74 and a chain 75.` 4A pressure 'shaft 76 on the. upper part of the rack at its rear end carries forwardly extending pres surelfingers 77 with upturned forward ends,

and reinforcements 78 or stiffening bars are w preferablyv added thereto. lf left free to swing about the shaft 76 the pressure ngers will follow thepload down as it settlesdown in the rack, butin order' to raise them-'put of the way in loading and to hold themin adjusted position, a hand crank 79 is mounted on the rack side within convenient reach of a person standing on the ground and is s'e-` 'of lthe end preferably ir cured to a pulley 82 connected as by a belt 80 or alike flexible connection, with a pulley S1 on the shaft 76, a dog 83 and ratchet wheel 84 being provided to hold the pulley 82 against turning and the fingers' in the desired position. y

In order to increase the pressure of the bars 77 upon the load beyond their wei ht when turned down upon the l.load with ,he dog 83 disengaged from ythe wheel 84, a tensioning dev' e is employed. This device is the form `of a seginentalarin 85 pivoted to the side ofthe rack in the path portions of a forked plate 86 that is securel to the 4shaft 76.. The downwardly projectii g end portion 87 of the yoke 85 is yieldinglj' connected as by a spring 88 with a lever 1 having a forward en'd portion provided with a handle 92 lind notches to adjustably interlock withva suitable member 91 nearthe forwardA end of the rack. By swinging the `yoke85 ineither direction, the necessary frictionalengagement to produce the desired result, obtains between theyoke andthe fork plate, thereby yieldingly turning the bars with the desired yielding pressure intocontact with the load, said bars or fingers, the

' shaft 76`aiid pulleys 81 and 82, being free to turn, as the' dog 83 vis always disengaged from its'ratchet except when it is desired to hold the shaft and fingers against turning.

It will be noted in the construction of the rack, the two stanchions 7 at the rear end of each rack side are offull length, extending to the top of the frame and forming a suitable .rigid frame work for supporting the beaters and presser bars, the longitudinal stanchions and secured to the upper end por -tions 12 of the other stanchions to form the hinged sides vof the rack. Asillustrated in the modified construction shown in Figs. 12

and 13, this supporting frame workis arranged to lfurther increase its strength and rigidity by extending Athe stanchions 95 and plane of the lower edges ofthe sills 5 andconnecting the stanchions 95 by a cross bar 97 which is vsecured to the rear ends of the sills. The part s In Fig. 12 suitable means is shown for raising and lowering each of the hinged sides, comprising a stub shaft 109I having a the hinged side with its longitudinal axis in 89 which is operated by a 'rod 90 f coincidence with the axes of the hinge pintles. By turning the crank, the side may be quickly and easilyswung downward or up# ward into closed .position where it may be held by latch bars 107siinilar to the bars 14,

' each V,of which are operated by a handle bar 1084 pivoted to the side within reach of the operator standing on the ground and conl nected at one end to thelatc'h bar interme diate the ends thereof by a link 109. f

One of the main features of 'this machine is thearrangement ofthe rack sides whereby as the load settlesand is moved rear-.p

w'ardly, it does not bind against the sides as it otherwise would, and this is due to the inclined and oblique'relation of the sideswhich lfrees the load'and permits the conveyers tog? readily move it against the beaters.

Another feature is the combination of longitu'dinal supporting sills adapted to besecured directlyto the holsters, with a plurality of carriers between and outside of the sills covering the bottom of the rack which therefore be made wide Aenough to give the desired capacity and will have the necessary strength and lightness of construction.

That portion of the rack upon which the greatest strain comes and which a diagonal brace98 sev i Other features of the invention arethe means by which the operator may adjust the vtension on the load so as to hold it properly in contact with the conveyer and thereby allow the latterrto force it evenly against the beaters; andthe disposition of the adjusting members so that they may be readily reached from the operators station and permit the user to yvary the feed as he, desires while the machine is' iii-operation.

Obviously changes in the details of construction inay `be made without departing from the spirit of my invention and I do not limit myself to the particular form` or arrangement of'parts.
