The spreader includes a. body part of hopper like form to carry the material and consisting of a pair of side walls 1, 2, each having a tapered part 3 and a rectangular part 4, the latter being of less height than the former and providing the upper portion of the side wall. Interposed between the walls 1, 2 as well as being secured thereto is a combined front wall and forward bottom section forming element 5, and the latter includes a perpendicular upper portion 6 forming the front wall and inwardly extending, depending, rearwardly inclined'lower portion 7 of greater' height than portion 6 and providing the front Section ofthe bottom ofr` the body part. The4 portion 7 has its lower edge arranged above the bottomfof the sidewalls.

Arranged between, as well as beingsecuredr to the walls 1, 2, is a combined back wall and rear bottom section forming element 8, and the latter includes a perpendicular upper portion 9 forming thefront wall and an inwardly extending, depending forwardly inclined lower portion 10 of greater height than portion 9 and providing the rear section of the bottom of the body part. The portion 10 has its lower edge arranged above the bot,- tom of the side walls. The lower Vedges'of portions 7 and 10 are arranged in parallel spaced alignment, and the spacezbetweensuch edges forms an outlet 11 for said Abody part. The top of the body partis reinforced at its front, back and' sides by anglebars 12.

Connected to the outer face of each side wall, at the bottomV of the latteris a rearwardly extending angle bar formed of a vertical and an outwardly directed horizontal flange, the` latter being extended from the bottoni of the former. The angle bars are indicated at 13, 14 and are oppositely disposed with respect to each other. The vertical andhorizontal flanges'ofeach bar are indicated at 15, 16 respectively. The bars 13, 14 extend rearwardly theA desired distance from the body pai-tand provide supports for a pair of handle members 17, each consisting of a vertical. part 18 secured at its lower end to the rear end of an angle bar and terminating at its upper end into a forwardly di rected part 19 which is secured against the outer face of an angle bar 12 at the top of a side wall. The angle bars13, 14V have mounted thereon and secured to the vertical flanges thereof a plank 20 providing a platform. The parts 18 of the handle members are secured to the horizontal flanges of the bars 13,14.

Secured to the lower face of and depending from the horizontal flange of each bar 13,14 is a pair of spaced bearing elements 21, 22. The former is positioned between the vertical median and back of the body part and the latter is arranged between the vertical median and front of the body part. The bearing elements 21, 22 on bar 13 align with those on bar 14. The outlet 11 is arranged at the vertical median of the body part and above the space formed between each pair of bearing elements. n

The spreader includes a pair of supporting wheels 23, 24 which are fixed to an axle 25 bodilyrotating with the wheels. l/Vhen the spreader is discharging forwardly the axle 25 is journaled in the aligning bearing ele ments'22 and when discharging rearwardly orbaclrwardly the axle 25 is `iournaled in the aligning bearing elements 21. The axle 25 is removably attached to thatpair of bearing elements in which it is journaled,

Fixed to the axle 25 is a spreader roller 26 of materially less diameterthan that of the wheels 23, 24. Preferablyv the ratio of'diam- V eters of the wheels and roll is 4:1, that is to say the diameter of each wheel being four times greater than that of the roll, and the latter is of a length to extend from the inner face of side-wall 1 Vto the inner face of side wall 2` The roll 26 is positioned between the sidewalls and below and spaced from the sections of the bottom ofthe body part. l On front discharge, roll 25 is arranged below bottom section 7 and has its axis arranged forwardly of outlet 11. On back or rear discharge, roll 26 is arranged below 'bottom sectionlO'and has its axis arranged rearwardly of outlet: 11. On front or forward discharge the major portion oft-he circumference-v of the roll 26 is 'arranged forwardly of outlet 11. On back or rear discharge the major .portion of the circumference of'thefroll is arranged rearwardly of outlet 11.

The discharge through outlet 11 is controlled by a front and a rear adjustable gate 27, 28l respectively, the former being slidably mounted against the outer face ofbottom sec'- tion 7 and the latter is slidably-mounted against the outer face of bottom section 10. Combined gate guide and retainersVv 29 are secured to the inner faces of the side walls A1, 2 and opposes in spaced relation the bottom sections 7, 10. The gates are disposed at opposite inclinations, are adjustable towards and from each other, and extend towards the vertical median. of the body part. The gates are' adjustable to vary the discharge through outlet 11, and when in such position depend below the side walls of the outlet. On forward discharge gate 27 controls the discharge of the material and gate 28 provides a stop to prevent the material from passing rearwardly from the body part. Onv rear or back discharge gate 2,8 controls the discharge of the material and gate 27 provides a stop to prevent the material passing forwardly from the body part. @n front or forward of roll 26 forwardly of the vertical median of the body part and the bottom edge of gate 27 is spaced from the peripheryof roll 26 in advance-of the point of the latter upon which seats gate 2S. The gate 27, when the spreader is discharging forwardly is adjusted to the desired extent to depend from the bottom section 7 to form in connection with roll 26 a material discharge passage 30. On back or rear discharge the gate 27 seats on the periphery of the roll 26 rearwardly ofthe vertical median of the body part and the bottom edge of gate 28 is spaced from the periphery of roll 26 rearwardly of the vertical median of the body part and the bottom edge of gate 28'. is spaced from the periphery of roll 26 rearwardly of the point of the latter upon which seats gate 27. The gate 28, when the spreader is discharging rearwardly is adj usted to the desired extent to depend from the bottom section 10 to form in connection with roll 26 a material discharge passage.

The gatesare adjusted from the rear of the body part and for such purpose-the gate 27 has attached'to each end an inclined pull bar 3l pivotally connected at its upper end as at 32 to the outer end of the angularlydisposed forward portion 33 of a rearwardly extending lever arm 34, Vthe latter being mounted to swing upon a pivot extended laterally from a support 36 securedto a front angle bar 12; rlhe arms 34 extend rearward- 1y beyond the rear wall 9, over the top of the body part .and provide means for elevating and lowering gate 27. Attached to the gate 28 for the purpose of elevating and lowering it is an upstanding handle member 37.

Attached to the bottom section 7 is a forwardly' directed tongue or hitching bar for connecting the latter to a traction means.
