OF MILWAUKEE, WISCONSIN, ASSIGNOR TO KOEfiING COM- PANY, OF MILWAUKEE, WISCONSIN, A. CORPORATION SUBGBADE PLANER AND CONCRETE-DISTRIBUTING MACHINE Application filed January 27, 1928. Serial No. 249,929.-
This invention has to do with machines for the preparation of-the sub-grade of a road or pavement area upon which concrete pavement 1s to be laid, and for supplying the neo- 5 essary concrete aggregates in mixed condition to the subgrade for the formation of said pavement. It has heretofore been proposed to utilize what are known as sub-grading ma chines for cutting and leveling off the area 10 upon which the concrete pavement is to be laid, and of course, concrete mixing and distributing machines, known as pavers, are commonly employed in the art.
The primary object of the present invenbeen to design a general machine including a concrete mixin unit, with associated distributing means or depositing the concrete in pro erly distributed condition upon the sub-gra e, said machine cooperatively mounted sub-grading instrumentalities adapted to be actually caused to progress with the main machine, and driven under certain conditions as to certain instrumentalities thereof by the same general power plant which advances the.
mixing unit, the distributing means and the sub-grading appliances.
A further object of the invention resides in assembling in a portable unit, concrete dis tributing instrumentalities in advance of which are arranged as a part of the same unit, the sub-grade instrumentalities, the two sets of means in their unit form being connected up so as to be advanced by the mixing plant 3 working in conjunction therewith, as the latter progresses over the sub-grade which is to be formed and upon which the concrete aggregates are to be deposited.
So far as I am aware, the assemblage of subgrading and concrete distributing means in a unit is new in the art, as well as the driving of the sub-grading instrumentalities of such a unit by the mixing machine power plant, whether these latter sub-grading instrumenin unit with the distributing means, or not.
In the accompanying drawings, I have illustrated certain types of my invention, which I prefer to employ, but I do not wish to be limited to the exact constructions depicted for they may be considerably changed within the purview and spirit of the invention as presented in my finally annexed claims. However, referring to the drawings, the figures thereof may be briefly described as follows Figure 1 is a perspective view showing a mixing machine or certain parts thereof, in dotted lines, and the sub-grading and distributing unit machine connected up therewith in full lines.
Figure 2 is a vertical longitudinal sectional view through the sub-grading and distributing instrumentalities primarily, the concrete mixer and its discharge chute being just generally shown in the relation of their cooperation.
Figure 3 is a fragmentary sectional view taken about on the line 33 of Figure 1.
Figure 4 is a side view of a modified form of sub-grading and distributing unit.
The mixing machine which I use as a part of my invention may be of any conventional type affording a portable construction wherein the concrete mixing drum A is carried by suitable traction devices such as the endless treads or belts B, the said parts being suitably associated by being mounted upon or connected with a chassis or frame structure C in any well known manner. A discharge chute 1 is adapted to conduct the mixed aggregates from the mixing drum A, and in this-construction said discharge chute will supply said mixed aggregates to the combined subgrading and distributing unit machine of my invention.
To the above end, the chute 1 discharges into a hopper 2 located centrally of the subgrading and distributing machine and equipped with oppositely extending troughs 3 which are virtually hopper extensions, these troughs being in complete communication at their inner ends with the hopper and having their outer ends closed as at 3. The parts 2 and 3 constitute a distributing device mounted at its ends upon frame members or channels 4 which are equipped with wheels or rollers of the flange type, designated 5, adapted to travel upon road rails or forms 6 of any well known type.
Arranged within the parts 2 and 3 of the distributing device are oppositely disposed screw leveling or conve ing members 7 by which the concrete fed into the hopper 2 is carried outwardly so as to fill the troughs or hopper extensions 3 from which the concrete is adapted to feed through an outlet opening at the bottom of the parts 2 and 3 which open ing is substantially continuous and which is controlled by a door 8.
In advance of the distributing device thus far described, are located earth-working' means comprising the sub-grade scarifying roller 9 having the scarifying teeth 10 and mounted upon a suitable axis 11 adapted to be driven so as to rotate the teeth 10 for earthworking operations. In rear of the parts just mentioned is the scraper blade 12 which may be made in sections and may be suitably adjustable upon a supporting beam 13 by means of the fastenings 15 provided as shown. It is contemplated to drive the 'scarifying device 9 positively by taking off power from the engine plant of the mixing machine, and to this end I utilize driving sprocket chains 16 which are engaged with sprockets 17 upon the inner ends of short shafts 18 disposed in alignment and mounted upon brackets 19 at their inner adjacent ends and in suitable bearings upon the frame members 4 at their outer ends.
Spur gears or any other suitable means 20 may be used to transmit motion from the shafts 18 to the scarifying device 9, by being geared to similar gears 21 upon the shaft 11. From the shaft 11 by means of sprockets 22 at the outer sides of the gears 21, and sprocket chains 23 connected with other sprockets 24,
I am enabled to transmit power from the power plant of the mixing machine to the outer ends of the screw members 7. For the above purpose, the sprockets 24 are carried by the opposite outer ends of the screw con- Yeyer shafts 7*. As a means of bracing the scraping device 12, the beam 13 thereof may be connected by bracing and connecting rods 25 to any suitable portion of the chassis or traction frame of the mixing machine, the rods 25 being directly attached to brackets 23 secured to the beam 13.
In Figure 4. I have illustrated a modified form of the scarifying means. In this instance, the scarifier comprises a beam 27 that is made up of fabricated units of an suitable type to which beam are attached -front and rear inclined scarifying teeth 28. The scraper 12 will be-used in conjunction with the scarifying means illustrated'in this view, and the driving connections may-include sprocket chains 29 and 30, traveling around suitable sprockets, and used primarily only for the purpose of transmitting power for the driving of the screw conveyer parts 7.
With the machine of m invention as above described, there are com ined concrete mixing and distributin devices and sub-grading appliances for leve ing the sub-grade in advance of laying the concrete thereon by the distributing devices, all in one machine. Moreover, the distributing scarifying and scraping features are assembled in a single unit, and moving-parts of the sub-gradin device are driven by the power plant of the main machine, which is a mixer in this particular instance, but might be any suitable traction machine for advancing the distributing and sub-grading unit.
As the main machine including the various devices described is advanced, it is obvious that batches of concrete may be deposited in the hopper 2 and will be forcibly carried into the extensions 3 thereof, so as to fill up the hopper. Thereupon, the said materials will be fed out from the bottom of the hopper upon the sub-grade previously prepared by being cut and smoothed off by the scarifying and scraping appliances operating in advance of the distributing device.
In Figure 4 is shown an adjusting device for the bottom door of the hopper 2 and trough extensions thereof, said adjusting means comprising one or more adjustable bolt and nut connections 32.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is
1. In combination, a concrete mixing machine, and a concrete distributing and earthworking unit associated therewith, comprising a distributing device arranged to deposit the concrete upon the sub-grade, earth leveling means arranged in advance of said distributing device, with common supporting means for the distributing device and the earth leveling means, and means common to the distributing device and earth working unit for driving the said instrumentalities and moving the machine over the subgrade.
2. In combination, a concrete mixing machine, vand a concrete distributing and earthworking unit associated therewith, comprising a distributing device arranged to deposit the concrete upon the sub-grade, and earth leveling means arranged in advance of said distributing device, with common supporting means for the distributing device and the earth leveling means, the earth leveling device comprising moving parts, and means for driving the moving parts ofthe earth-workfor driving said scarifier from the concrete mixing machine.
4. In combination, a concrete mixing machine, and a concrete distributing and earthworking unit associated therewith, comprising a distributing device arran ed to deposit the concrete upon the sub-gra e, and earth leveling means arranged in advance of said distributing device, with common supporting means for the distributing device and the earth leveling means, the earth-working device comprising moving parts and the distributing device including a moving part, with connections for driving the said movmg parts of the earth-working and distributing devices from the concrete mixer.
