This invention relatesv to that type-of Spreaders in which-aho-pper-is mounted to run upon road :surface at the rear of a dumpinggbodytruckand-tobe drawn along by the truck and receive fromthe truckbody brokenstone or other road material which will be spreadg overi the roadesurface asit discharges from the hopper. The'presentinvention relates particularlyto the rear gate or cutoff of the hopper and has for itsa object the provision of-means whereby-the road Inaterial may be spread to" an even surfaceor permitted to accumulate to a'greater height at the center and gradually taper toward the sides so as to provide a-crown for the road. The invention provides a supplemental blade which is independently adjustable upon the rear gate and includes meanswhereby bending 'or warping of the supplemental blade under stress will be effectually resisted. The invention is illustrated in the accompanying drawings and will be hereinafter fully described, the novel features-beingparticularly defined in the appended claims} In the annexed drawings v Figure 1 is a side elevation of the rearend portion of a dumpin 'truck and my'improved spreader connected t erew-ith;

Fig. 2 is a rear elevation of the spreader, and I Fig. 3 is an enlargeddetail vertical section throughthe rear gate andthe supplemental blade mounted thereon.

In the particular arrangementillustrated in Fig 1, the reference numeral lindicates a endgate 3 which may swing outwardlyyto permit discharge of-material when" the body is swung. to a dumpingposition, as shown. Hangersl are secured to the sills of-the-chassis adjacent the-rear end thereof anda cross lower ends' of thcsehangers, the hangers-being reinforced bybraces "6 extending forwar'dlytherefrom to "the-sills; The hopper or body 7"of the spreader has a downwardly and rearwardly inclined front wall upon the 'aresuspension rods :13 which passthrough the draft bar-sand are equippediwith wing nuts some 'ofw-hiclr are pivoted the 4 rear ends -of draft bars 10" which extend forwardly and have their front ends: formed into hooks :11 with beveled-' forw-ard lower edges whereby,

if the truck be backed *toward the hopper, i

the draft bars willbecaused to ride over the cross bar and drop into engagement therewithx Pivotally hung above the draft bars 10 a depending crank arm 17 having itslower end disposed to engage below the. draft hooks, I as atr'l8. Asimilarcrank armsl9r-rises from the rock shaftz and is pivoted to; an operating front side =of which are reinforcing- :bars to mountedin the braces-6 and is equipped .with

rod=20 which extendsforwardly to a' point near thevoperators seat where it may be equipped withla lever or other manipulating device; If the: crank 17 be swungpupwardly and rearwardly, :the-hooks 11 will be lifted from the cross barf) so that the-truckmay then be fdI'lWGIl' forward away from the hopper;

Thezhopper'issupported byrollers 21 upon ashaft 22 whichQ-is journaled in bearings 23,

the i bearings being in; turn bolted to blocks .24 which-fare secured to some of the rein'forcements uponthefrontwall of the hopper. The blocks 241 may be of any form whichwill'acconnnodatea plurality 0f openings through the. lower front wall of the. same'pto' "receive fastening bolts; whereby-the bearingsamay be securedata relatively higheror lower point ofthei hopper :so that the bottom of the hop -per will beidisp'osed'xat a greater or less height above the ground surface; and the depth of the spread may be thereby approximately regulated; Shoes 28. are also'connected with the -front wall-ofr the hopper to run: upon the ground in paths following the outer sides of the truck wh'eels :while the rollers 21: are in drawings is intended more particularly for spreading broken stone andthe end or SlClG walls of the hopper areso formed as to terminate in their rear portions at an appreciable distance above the bottom of the hopper.

'Slidably mounted upon the end or sidewalls of the hopper are end gates 80 which, when set in their lowest position, will prevent lateral spread of the material as it passes from the hopper but by setting these end gates at higher points the material may be permitted 7 to spread laterally at the same time that it passes to the rear so that the formation of shoulders or of'wide spread will be facilitated. Upon the outer side of the end gate adjacent the upper end thereof is a. loop or bracket 81 through which passes a hanger 82 rigidly secured upon the frame of the hopper at the top of the same so that it constitutes a guide for the end gate in the vertical adjustment of thelatter, it being under stood that the side edges of the end gate are engaged behind cleats or flanges 88 on the hopper so that the end gate'will be eifectually held to the hopper. A set bolt 84 is mounted in the loop or bracket 81 and is adapted to be turned home against the hanger 82 so as to secure the end gate in its set position.

The rear gate or cut-ofl' 85 is of substantial construction and is provided at its edges with vertical racks or notched bars 86 which are arranged to mate with notched bars orracks 87 rigidly secured upon therear wall of'the hopper at the ends of the same. The racks 87 have laterally projecting flanges 88 and upon the ends of the gate are secured'arms 89 which project forward past the racks 87 and. the flanges 88 adjacent the ends of the hopper, braces 90 being secured to and extending between the said-arms and the gate, as clearly shown in Fig. 1. Mounted upon the arms 89 are cams or eccentric levers 91 which are adapted to bind against the front sides of the respective flanges 88 and thereby firmly clamp the racks 86 and 87 in engagement so that the gate will be held in its setiposition and will ride over the top of the discharging road material so as to reduce the same to a desired level even surface. By swinging the locking lever 91 upwardly, the gate maybe raised to the desired height and by then turning the lever downwardly the gate will be firmly secured.

Secured upon the rear side of the gate 85 along the lower edge of the sameis an angle 'bar 91 having openings formed through its rearwardly projecting .web at intervals. Se-

cured to this angle bar 91, which serves as a -:blade 93. which is adapted todepend below Lthe gate 85 and serve as a cut-ofl' to produce a level upper surface on the road material.

The blade 93-has rigidly secured thereto posts or hangers 94 which extend upwardly therefrom through the openings in'th-e horizontal web of.the angle bar 91 so that they serve as guidesvfor the blade in itsvertical movements. The brackets .92 also serve as guides for the blade and in addition reinforce the blade so as to resist any tendency of the same to buckle or warp under the strain imposed thereon by the load of road material over which it works. The posts 94 also serve as braces for the blade and by their movement through the openings in the bar 91 serve .to

prevent swaying of the blade as it is adjusted vertically. Some of the posts or hangers 94 adjacent the respective ends of the blade are made somewhat wider than the other posts andhave links 95 pivoted to their upper ends, the upper ends ofsaid linksbeing pivoted to the free ends of the lower arms 96 of angle levers which are fulcrumed upon the gate 85 at the upper edge of the same and extend upwardly, as shown at 97, said levers being equipped Withlatches 98 cooperating with holding racks 99 secured rigidly upon the gate 85 so that the levers may be held in a set position. It should be noted, particularly upon reference to Fig. 2, that the lower arms 96 of the levers extend in opposite directions or toward each other so that the levers areoscillated in opposite directions. Each lever is equipped at its upper extremity with a bail or small loop 100 which is adapted to be engaged over the upper free end of the handle of the cooperating latch and thereby hold the latch out of engagement with the rack. There is also provided acoupling bar 101 having a ;notch 102 in its lower edge near each end, these notches being adapted to be engaged over studs or lugsgl03 on the respective levers, one lever, that shown at the left in Fig. 2, having the stud above its fulcrum and the otherlever, that shown at the right in 1 Fig. 2, being extended below the fulcrum and having the stud at the lower end of the extension. It will be understood that,if the loop 100 uponone lever be engaged over the adjacent latch handle, the latch on said lever the movement of the active lever being transpling bar 101 in an obvious manner. It will mitted tothe inactive lever through the couthus be seen that the blade 93 may be adjusted from either side of the hopper and it will also be noted that if the coupling bar be removed the levers may be independently adjusted so that either end of the blade may be set higher than the opposite end thereof and the blade thus adjusted to permit a greater deposit of material under one end than under the other end so that a crown may be formed upon the road.

By the use of this supplemental adjustable blade, a very accurate deposit of road material may be attained, the gate 85 being set to permit the load to be deposited approximately to the desired depth and the blade being independently adjusted so as to efiect a finer closer adjustment. The guide brackets and posts or hangers cooperating with the blade serve to hold it to a true rectilinear vertical path when it is being adjusted so that there will be no binding of the same against the gate and the openings through which the guide posts or han ers pass are of such dimensions that they Wlll effectually guide the gate but at the same time permit it to be canted within limits by the independent operation of the levers in order to produce the desired crown upon the road. The device is exceedingly simple and eflicient and will not add perceptibly to the draft of the apparatus.

Having thus described the invention, I claim:

1. The combination with a hopper to be drawn over a road at the rear of a dumping vehicle and receive road material from said vehicle, of a back gate mounted upon the rear wall of the hopper and vertically adjustable thereon, a supplemental blade carried directly by the gate, and means mounted on the gate above the blade for vertically adjusting the blade.

2.
