Patented May 21, 1940 UNITED STATES PATENT `OFFICE ,2,201,534v MEANS Foa ROAD SURFACING Charles V. Hallenbeck, Denver, Colo. Application July 1, 1937, Serial No. 151,429 17 claims.` (o1. 94-44) This invention relates to improvements in means for and method of road-surfacing.
An object of the invention is to provide a machine which will automatically size-classify mixed road surfacing material such as gravel, rock chips or the like. f
Another object is to provide a machine of this kind that will deposit the sized material in sizeg'raded strata on and along the road bed to be surfaced, in the correct sequence of deposition,
A further object is the provision of a roadsurfacing machine that will screen, spread and roll the material in one continuous operation.
A still further object is to provide such a 1nachine that can readily be refilled with surfacing materials while maintaining it in its operating position.
Still another object isthe provision of a roadsurfacing machine that is self-propelled and which can be steered and otherwise fully controlled by one operator from a station thereon.
A still further object is to provide a machine for this purpose, that travels only on the surfaced road, it having no bearing on the unsurfaced road-bed. v
Still another object of this 'invention is the teaching of a method of continuous screening, depositing and rolling, of road-surfacing material in size-classified strata and in correct sequence of deposition. Y
Other objects and advantages reside in details of design and construction which will be more fully disclosed in the following description and in the drawings wherein vlike parts are similarly designated and in which: p v Figure l is a general side elevation of a roadsurfacing machine built according to this invention;
l Figure 2 is a plan view of the same; Figure 3 is a side elevation of a similar machine, drawn on a smaller scale, and showing the means and method of supplying the machine with surfacing material;
Figure i is a side elevation, drawn on a larger scale, of a portable ramp built in accordance with this invention; and
Figure 5 is an enlarged fragmentary sectional View taken approximately on line 5--5 of Figure 2.
In the drawings, reference numeral l2 denotes a general supporting frame that is carried on propelling rollers i3 and idler roller |4 which overlaps the tracks of the propelling rollers in the direction of travel, as indicated by the arrow. On the forward end of the frame is a power plant ,intermediary of drive chains 20.
An open top, V-shaped hopper 2| is mounted onthe frame in a centrallocation and has a relatively narrow transverse discharge slot 22 at its lower extremity. A feed roller 23 is driven in a forward direction of rotation by means of a sprocket 24 on one of the propeller rollers, and a chain 25 which cooperates with a driven sprocket 2t on the feed roller.
Immediately below the feed roller is a forwardly'inclined screen assembly 2l, which is resilientlyy suspended by means of leaf springs 28,
the upper ends of which are carried by the frame. The screen assembly comprises a series structure. of ribs 2S that serve to strengthen and suDDGt the assembly and to provide a series of channels therebetween that extend parallel to the direction of travel of the machine.
Beneath the ribs 29 is a coarse screen 30, onk
top of which is a finer screen 3| covering approximately the rear half of the coarse screen. It is not necessary to have the coarse screen extend back under the finer screen. A fine screen and a coarse screen may be placed edge tor edge with the liner screen to the rear of the coarser one.
A V-belt pulley 32 is driven by the power takeoi which is under control of an operating lever 33. A belt k3i is driven by the pulley 32 and passes around an idler 35, rto drive a pulley 36 on a shaft 3l, which carries a pair of eccentrics 38, having connecting rods 39, which 'are connected with the screen assembly to impart vibratory movement thereto.
A lever 4|! is carried on the frame and is connected by means of a cable 4| to a clutch throwout varm 42, so that an operator standing on an operators platform 43 may disengage or engage force when wanted, to the left-hand propelling roller I3.
A number of weights 49 are carried on platforms to the rear of the propelling rollers to counterbalance the weight of the machine that is forward of the axis of the propelling rollers, so that the entire structure ahead of this axis is suspended as a cantilever without touching the surface over which the machine is operated.
Figure 5 illustrates in detail the structure of the forwardly inclined vibratory screen and its actuating eccentric mechanism.
Figures 3 and l illustrates a portable lamp 5l?, y which may be attached to a rear plate 5! carried' on the frame I2, by means of pins 52. The ramp comprises an automotive-type running gear 53 and a track 55, which is suspended above the running gear by means of conventional leaf springs 55, so that the lower extremity 5S of the track is normally spaced away from the surface over which it is travelling, as shown at 51.
Operation In use, an operator starts the power plant motor in a conventional manner and may thereafter control the machine from his station on platform 43. A truck driver backs a truck 58 up the ramp 5Fl, as illustrated in Figure 3, to dump a load of mixed-size gravel or rock chips for road surfacing, into the hopper 2|. The weight of the truck compresses the springs 55 so that the lower ends of the ramp track bear on the ground surface, as shown at 60. After the load of material has been deposited in the hopper 2|, the driver of truck 58 may return to the source of supply for another load, while the operator of the surfacing machine proceeds to spread and to roll the material,
The clutch is engaged by means of lever 40 and cable 4|, to transmit driving torque differentially to the two propelling rollers I3. The machine is guided by differential application of braking force to the rollers, by means of the levers 44 and 41 in the well-known manner. The forward motion of the rollers I3 transmits rotative driving force to the feed roller 23 at the lower end of the hopper, which movement will deliver a stream of mixed-size material onto the forwardly inclined screen assembly, which is being vibrated by the ,mechanism above'described.
It will be clearly seen in Figures 1 and 5 that as the mixed-size material falls upon the screen assembly, it falls rst upon the ner screen 3l so that the finest material, indicated at 6I, will pass through at this location. As the material progresses forwardly and downwardly along the screen surface, it passes onto the coarser screen 3D, where coarser material, indicated at 62, will pass through. The material 63 that is too large to pass through any screen mesh, will be discharged forwardly olf of the forward end of the screen assembly, and it will be seen that, since the direction of travel is as indicated by the arrows in Figures 1 and 3, the coarsest material 63 will be deposited rst in the forwardmost position on the road grade 64. The intermediate size material G2 will next be deposited in a stratum on top ofthe coarsest material, and the nest material 6I will be deposited on the uppermost surface. As the machine progresses forwardly, the rollers will smooth and compact the siufacing material as shown at 65 in Figure 1.
It will thus be seen that in a single progressive operation, this machine screens, classies and deposits surfacing material in strata, with the coarsest material in the lowermost position and the finest on the surface, which is an optimum method of road construction. The machine then rolls, smoothes and compacts the deposited material to a finished surface as it continues its progressive movement, and all of its functions are under the control of a single operator from his station 43.
In the meantime, one or more truck drivers may drive back and forth from the source of material supply to replenish the material in the hopper 2I, so that the operation of the surfacing machine is only momentarily interrupted to receive a truck load of material at predetermined intervals.
It is understood that the ramp 50 will normally be attached to the spreader and trail along therewith, to receive the supply-trucks upon their arrival.
