Patented Sept. 18, 1934 UNITED STATES PATENT OFFICE The present invention relates to improvements in concrete spreaders adapted to be used in road construction, and its principal object is to provide a concrete spreader that will uniformly,
form cross-section as new concrete is added thereto.
a further object of the invention .is to provide means following the advancing body of conconcrete whereby a single operation is made to place the concrete on the road bed in its final form. Further objects and advantages of my inven- 5 tion will appear as the specification proceeds.
The preferred form of my invention is illustrated'in the accompanying drawings in which Figure 1 shows a top plan view of my invention; Figure 2 a rear view thereof;

While I'have shown and described only the 5 preferred form of my invention, I wish to have it understood that various changes and modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention. More particularly I wish to have it understood that my machine may be used for spreading asphaltum or any other road material to which it may be adapted.
In its preferred form my machine comprises a carriage 1, including a frame 2, of rectangular form, open in front and supported byfour wheels 3 adapted to ride on header boards 4 arranged on opposite sides of the road bed in conventional road construction. It will be understood that the header boards are arranged in such a manner that the top edges of the header boards are on a level with the surface of the road to be constructed and serve as a guide for the filling operation. It should be understood that while for the purposes of the illustration of my 0 crete for striking off and leveling the discharged invention it is assumed that the road is to be 7 constructed with a level surface, the same machine may be used with some slight changes in form for producing a cambered surface.
The rear wheels are preferably driven from one source of power indicated at 5 such as a gasoline engine mounted on the rear portion of the carriage and connected through a shaft 6, either one of two sets of gears 7 and 8, the shaft 9 and a chain drive 10. The front wheels are driven from the rear wheels through chains 11. Of the two sets of gears 7 and 8, the former is for direct drive and the latter for reverse drive, a suitable clutch mechanism 12 being interposed for selective use of one or the other.
The carriage supports 'a strong rectangular frame 13 made preferably of channel irons and extending transversely across the carriage between the front and rear wheels respectively. The end members 14 of this frame have slant- 9.! ing guide rails 15 fixed to the inner faces there-' of in suitable spaced relation, each of these rails serving as a support for a truck 16 carrying a plate 17, the two plates being arranged in converging relation and extending throughout the length of the frame so as to form an open bottom trough or hopper coextensive in length with the width of the road bed. Each of, these plates 17 is formed with end flanges 17' lying against the faces of the end plates 14' and covered in 17 is reciprocated by means of two arms 18 fixed to the shaft 19 and pivoted to lugs 20 projecting from the under face of the plate 17, rocking motion being imparted to the shaft 19 by a second arm 21 operated from an eccentric 22, through a connecting link 23. The eccentric 22 is fixed to the shaft 6. The front plate 17 is reciprocated by means of two arms 24 extending from, the inner face. of the plate throughout the length thereof.
In operation when the hopper defined by-the two plates 17 and the two end walls 14 is filled with concrete and the carriage is made to advance and the plates 17 are made to reciprocate, the entire body of concrete will be under continuous agitation, and due to the steps 29, will be rocked back and forth and at the same time driven downward to be discharged upon the road bed through the opening between the two plates 17.
It should be observed that this particular construction not only allows the concrete to be fed upon the road bed simultaneously over the entire width thereof but it also continues the process of mixing the concrete to the very point where it is discharged in its permanent place upon the road bed, whereby the resulting bed of concrete is much improved over a bed made in the conventional manner by first discharging the concrete upon the road bed in piles, then spreading the piles by manual labor, and thereafter grading the concrete by machinery. The steps are arranged so that their under faces are almost at right angles with the plate 17, while the upper faces are disposed at a more acute angle which causes the concrete to be thrown inwardly in a rocking motion on the upward movement of each plate, and which causes the concrete to be tamped downward upon the road bed on the downward movement of each plate.
The hopper consisting of the two plates 17 has also means associated therewith in the shuttle 30 for evenly spreading concrete discharged into the hopper. This shuttle or leveler comprises a frame 31 of considerably less length than the hopper, and is suspended over the hopper by hangers 32 formed to extend over the upper edges of the two plates 17 and supported on four wheels 33 riding on tracks 34 provided on the inner faces of the frame 13. The end walls of the shuttle 30 have-plates 35 suspended therefrom by means of hinges 36 arranged in such a manner that each plate 35 may swing inwardly but not outwardly. The bottom edge of each plate extends substantially halfway into the hopper, the depth of the plate depending somewhat upon the amount of concrete to be discharged at one time into the hopper. The plates 35 are sufficiently long to extend substantially from one plate 17 to the other plate 17, but in such a manner as to clear the steps 29 in their uppermost position. The shuttle may be moved back and forth over the hopper (so as to level material dumped thereinto) by means of chains 37, fastened to the hangers 32 as at 38, and passing over sprockets 39 on two shafts 40 running along the edges of the carriage, one of the shafts 40 evenly over the entire hopper.
being driven through beveled gears 41 from a jack shaft 42, which latter may receive revolving motion from the shaft 6 through either the direct gearing 43 or the reverse gearing 44, a suitable clutch mechanism 45 being provided for rendering one or the other of the two gears active.
when concrete is dumped into the shuttle and the latter is made to advance in one or the other direction, the advance plate 35 may swing inwardly to clear obstacles presented in the shape of material lying outside the shuttle, while the rear plate 35 is held in vertical position and pushes any material rising beyond its bottom edge in front of it, and leveling the concrete One trip back and forth will usually'be sufficient to evenly spread a new charge over the entire surface of the-"hopper.
After the material has been discharged from the bottom of thehopper so as to be uniformly distributed over the entire widthof the road bed, it is engaged by the strike-off trowel 46 which extends transversely through the machine immediately following the rear plate 17, the trowel being made in the form of a strip of metal of proper width arranged at a slight angle to the road bed so that its leading edge issiightly higher than the ultimate height of the road bed, while its rear edge is on a level with the header boards defining the ultimate height of the road bed. This trowel plate is supported on two shoes 47 adapted to ride on the two header boards and formed with V-shaped angles or flanges 48 adapted to divert material lying on the top surface of the header boards either toward the road bed or toward the outside.
It will be seen that this trowel strikes off the I journalled on the shaft 19, and engage with end 1 pieces 51 rising from the shoes 47 through a pin and slot arrangement 52. The arms 49 may be rocked by means of a second pair of arms 53 fastened near the ends of a transverse shaft 53' and connected with the arms 49 through links 1 54 (see Fig. 6). A manually actuated lever 55 is attached to the shaft 53' and may be moved for raising or lowering the trowel. An upright 56 is provided with notches 55. for receiving a conventional latch 56' on the lever 55 and thus secure the latter "in adjusted position.
The end pieces 51 of the shoes 47 and the trowel ride between'guldes 60 fastened to the end walls'14 and each of the end pieces is formed with a clip 57 adapted to rest on a flange 59 (see Figure 13) of one of the guides 60 when the trowel is in operative position. In case it should be desired to raisethe trowel slightly relative to the header boards, I provide a screw adjustment as shown. at 58 which allows the member 51 to be raised relative to the guides 60.
The operation of the machine is substantially as follows: After the main carriage has been properly placed on the header boards, the concrete is dropped more or less promiscuously into the hopperby any suitable loading device. Preferably a major quantity of the concrete is dropped over the shuttle 30 wherever it may be at that time. The shuttle is then made, by suitable operation of the clutch mechanism 45,
to move back and forth over the entire hopper whereby the concrete is spread over the entire hopper area to a uniform height.
Simultaneously with this leveling of the material in the hopper, the plates 1'7 will be reciprocated whereby the entire body of concrete is agitated in a certain rocking motion, and fed downwardly upon the road bed as the carriage advances. fluous material and firmly presses the remaining material upon the road bed so as to leave an even and finished surface. It will be noted that advance movements of the truck are under the control of the operator independently of the control of the shuttle .movement so. that the operator at any time may stopthe whole carriage if the spreading operation does not keep up with the advance of the machine. In this manner a firm and solid bed of concrete is obtained from freshlyvmixed material, and all manual labor in the spreading of material is eliminated.
