ASPHALT srannnnn.
Application led September 18, 1925, Serial No. 57,187. Renewed March 28, 1927.
This invention relates to new and useful improvements in spreading devices and particularly to devices for spreading material von streets. such as asphalt, stones, sand, or the like paving materials.
One object of the invention is to provide a device of this character which is adapted to be connected to the rear end of a wagon,
whereby, upon tilting thebox of the wagon, lin the act of dumping the load, such material will be evenly spread on the sur-face of the of the box 12, immediately in rear of the street or road.'
Another object is to provide a device of this character by means of which the material may be spread to the desired or required thickness, lthe device being readily adjustable to permit variations in the thickness of the stream of material issuing from the wa on. ther objects and advantages willbe apparent from the following description when Y taken iii-connection with the accompanying drawings. i
Infthe drawings: Figure 1 is a side elevation of a wagon, in dumping position, and equipped with' the present invention. Figure-2 is a top plan view of the same. Figure ,3 is'arear elevation of the same. Eigure' 4 is a vertical longitudinal central sectional view on the line 4-4 of Figure y2.
Referring particularly tothe accompanying drawings, 10 represents a wagon which mounted a downwardly and rearwardly inv 'clined baiile14,which is arranged to rest on is adapted for use.
Mounted on. the rear end ofthe wagon box includes ythe dumping body or box 11,'ir connection with which the present invention' is a box I12, the upper and rear portions of which are open, as clearly seen in the drawings, and particularlyinFigure 4. Mounted in the upper rear portion of thebox is a transverse b'ar '13, on which is movably the upper surface of the asphalt' as such asf phalt flows from the wagon box into the box '12. The lower free edge portion of thisl -baile plate isformed with the series'of regularly spaced teeth 15,'between which are dis posed the 'grate bars 16. These grate bars are carried by a transverse shaft 17, disposed below the bottom of the box 12, 'and have their lower ends in position to hold back the asphalt. The portion of the box 12,
forwardly of the grate 16, is, in effect, a hop-v per, while that portion to the rear of the with a series of ratchet teeth 20, for en agement with the transverse bar 21, where y to accomplish the rocking of the rate bars toward and away from the aspha t.
Mounted transversely in the chute portion grate bars 16, is a shaft22, and fixed on this shaft are the plurality of radially eXtendin raker arms 23, which play between the teet or grate bars 16, to draw the asphalt from the load into the discharging chute portion. By the adjustment of the grate bars forward'ly and rearwardly', the raker arms can dig into the asphalt, `between said bars, to greater or lesser degrees, whereby to regu` late the amount of asphalt to be drawn from the hopper portion of the box. The ends of t 22 project to suitable distances be.v
the sha yond the sides of the hopper, and mounted on theseends are the gears 24. Similarlymounted in the sides of the chute portion of i the box 12, rearwardly of the shaft 22, is a' shaft 25, and secured to this shaft, and extending radially therefrom, are the longitudinally extending spreader bars or blades 26. On the ends of the shaft 25, which project through the sides of the chute portion,
are the ears 27. Mounted'on the shafts 28, carried y the sides of the hopper, `intermediate the projecting ends of the shafts 22 and 25, are the internally toothed wheels 29,
which engage with the gears 24 and 27. to
simultaneously drive the shafts 22 and 25.
As clearly seenv in Figure 1, 4when the wagon box is tilted intov dumping position, the asphalt will run down against the grate bars 16,- and the .wheels 29 engage on the ground. As the wagon is pulled forwardly, 1n. this position, the wheels 29 will drive the shafts 22 and 25, so that the raker arms will drag the asphalt from the load, through the grate bars, from the hopper into lthe chute portion, whereit is moved along by' tho spreader. bars or blades 26, and out onto the road or street surface.
` By adjusting the grate bars toward or away from the raker arms, such arms will pass between the bars to greater or lesser degrees', thereby raking out more or less of the asphalt, with the result that the asphalt transversely will be delivered to the spreader bars in eater or lesser quantities, thereby regulating the thickness of the asphalt spread onto the road surface.
What is claimdis: 1. An asphalt spreading device comprising a receptacle for containing asphalt, a vertically slotted plate against which the load of asphalt rests, a rotary raker mounted in position to rake the asphalt through the slots of the plate, means for discharging vand. spreading, onto a street surface, the material thus raked, `and means for moving the slotted plate toward and away from the raker, whereby to permit the latter to move through the slots to greater or lesser degrees and thereby regulate the amount of asphalt fed to the discharging and spreading means.v
2. An asphalt spreading device comprising an inclined dumping receptacle, ground Wheels supporting the lower end of the receptacle, a vertical plate movably mounted in the receptacle and arranged to receive the load of asphalt thereagainst, said plate having openin s therein, a raker driven by the ground w eels and movable through said openings to draw asphalt therethrough, means below the raker for moving the asphalt out onto a street surface, and means for -moving the vertical plate whereby to regulate the depth to which the raker enters the load of asphalt and the amount thereof drawn out by the raker.
3. An asphalt spreading device including i an inclined receptacle, a transverse bathe plate' the load vof asphalt rests,l said against which plate being pivotally connected to the lower portion of the receptacle and having vertical slots therein, wheels supporting the receptacle, a rotary raking device driven by the ground wheels and having teeth moving through the slots of the plate to draw' asphalt through said slots, rotary means for receiving the asphalt thus raked through the slots and discharging saine vonto a street surface, a plate movably mounted in the recep tacle 'and having projections engaged in said slots for directing the asphalt toward the slots, and means for adjusting the slotted plate toward and away from the raker whereby to permit the raker to dig to different-depths' into the asphalt through said slots. ,f
In testiinony whereof I affix my signature.
