oNiTEo STATES PATENT OFFICE.
JOHN I. more, or oLnvnLAnn nnren'rs, OHIO, ASSIGNOR, BY mnsnn ASSIGNMENTS,
no xonnnme conrANY, or MILWAUKEE, wrsoonsm, A CORPORATION or wrs- Application filed March 26, 1921. Serial No. 455,886.
To all wiwm it may concern: v Be it known that 1', JOHN F. Home, a citizen of the United States, residing at. 3111 orced Concrete Roads, of which the follow ing is a specification.
It From the viewpoint of advanced engineering, the development of concrete road construction today points to the necessit of employing metal reenforcementfor suc roads for obviating as much as possible the I! liability of longitudinal cracking or breakmg. This cracking or breaking of the concrete road is due of course to dilferent causes, but it has been found that the liability of the cracking is much reduced when 'metal' reenforcing is utilized, somewhat after the manner of the use of this material in concrete construction generally.
The purpose in view in the development of the present .invention has been to devise a machine and method for facilitating the laying of concrete roads in two'sections, a base section and surface section, with the reenforcing properly disposed between said .sections. The common method in use today for doing the above work has been to lay the base or bed section of concrete upon the subgrade, by a suitable distributing maf chine, then dispose upon said base section suitably cut sections of the reenforcing metal. The second step just referred to is attended-to by hand -and involves expensive manual labor, at the same time delaying the general operation of constructing the road because the mixing and distributing machine usually employed cannot progress until after it has laid the surface layer or section of concrete upon the base layer or section, and upon the previously deposited reenforcing.
The machine or method proposed by me permits of applying the reenforcing material to the base section of concrete first laid by mechanical devices, and in a continuous manner as the machine progresses. Furthermore, the invention involves the laying of the surface section of concrete simultaneously with the laying of the reenforcement in position upon the base section. The'invention involves additionally the method of simultaneously laying the surface section of concrete and the reenforcement in a continuous and progressive manner as the dis tributing machine by which the surface section aforesaid is deposited steadily progresses in the road laying operation.
The invention involves additionally theutilization of a derrick type loading means for the distributing and mixing unit employed, to carry the aggregates thereto, said derrick means being additionally available for lifting bales, or similar supplies of reenforcing material into place upon the machine ready to-be fed therefrom as the machine progresses.
' In the accompanying drawings:-
Figure 1 isa. side view of distributing machines for mixing concrete, distributing the concrete in two layers, and feeding the reenforcing'to the road bed for deposit upon the base section of toncrete first laid.
In the drawings A denotes the subgrade on which the road 'is to be constructed, B the baselayer or section of concrete adapted to be deposited upon the subgrade by a distributing machine 2 constructed largely in accordance with the type of machine illustrated in United States Letters Patent of Lichtenberg No. 1,141,470, issued June 1, 1915. The machine 2 has a distributin bucket 5 adapted to travel on a boom 4 an a suitable mixer may be provided for said machine, same being partially illustrated at 3. I show at C a surface layer ofcon-O crete as when being deposited upon the base layer B; also there is illustrated at D the reenforcing material in the act of being laid upon the base section B of concrete.
To lay the surface section C of the concrete and the reenforcing D, I have devised a special machine designated 8 and consisting of suitable framework having the supportingwheels 9 arranged totravel upon the road forms E which act as rails for-the support of the machine 8. At one end the machine 8 is equipped with a carrier or suitable supporting means 10 for a bale 10 of reenfiorcing material. The bale 10 is supported by a removable shaft 10" which is used in connection with a grapple on the v derrick device hereafter described, to faciliautomatically feeds onto the bed section B the boom 4 of the machine 8, and this bucket 1 of the road,this bed section being first laid. The machine 8' has a derrick 13 supported on its framework and comprising a mast with the boom- '14. By this derrick the loading bucket, which may be a batch box, desi ated 15, may be removed from the truc or car of andndustrial railway and dumped into the hopper '16, from which its contents pass into the mixer 17. The mixer 17 is adapted to feed mixed aggregates into the distributing bucket 18 on 18 supplies the aggregates to be laid as the surface or top section C of the road. These surface aggregates are deposited upon the reenforcing D as the latter is fed to the surface of the bed section B of theroad. Y After being laid the bed section B of concrete will be comparatively soft, but will have ample body to'carry the reenforcing D as it is laid, and then in continuous proc- 68s the surface aggregates are [deposited on top of the base section B, upon the reenforcin D. p
By the machine above described, and practicing the method set forth, it is. evident that a complete reenforced road may be. laid in a continuous progressive o ration,-
that no manual work lslentailed in andling the'reenforcing, and that the surface layer or section of the road bed may be laid quickly after the bed section is deposited,
and will unite firmly with the bed section to provide a solid, monolithic, reenforced, road structure. r
It will be understood that any suitable power driven feeding rolls such as designated at 20 may be carried by the supporting means for the metal reenforcement whereby to positively pull or unwind the same. from I the bale or reeled formation thereof. 1
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a machine 'for laying concrete reenforcing, in combination, a wheeled support having wheels adapted to travel upon road forms at opposite sides of a road sub-grade, a carrier for metal reenforcing mounted upon said support, a series of strai htening and feedin rollers adjacent to sai carrier and carrie by said support for receiving and straightening the reenforcing as it passes over the roll to the sub-grade, a guide roll carried by said support for directing the reenforcingproperly to its position on the sub-grade, a power plant upon the support, driving connections between therpower plant and feeding rollers, and driving connections' between the power plant and wheels of the support, substantially as described.
2. In a machine for laying concretereenforcing, in combination a wheeled support 4 having wheels adapted to travel upon road "forms at opposite sides of a road sub-grade,
a carrier for a supply ofmetal reenforcing carried by said support, a power plant on said support, means for dispensing the re-' enforcing supported by the carrler operated' by said power plant, and means for advancing the portable support, comprisin drivin mechanism for. its wheels opera from e power lant. In testimony w ereof 4 JOHN F. ROBB.
