Abstract

An apparatus capable of self power or being towed and specifically designed to distribute and/or apply cementitious material, and in particular, pervious concrete, over a given surface area such as a roadway or the like. A support frame has mounted thereon a distributor casing specifically configured to direct cementitious material in layer form along a transverse length relative to the direction of travel of the support frame. A delivery hopper moves transversely on the frame and along the length of the casing and serves to continuously feed cementitious material to the casing. Material such as pervious concrete is continuously discharged from the distributor casing by a percussive action imparted to it by forward motion of the frame. A blade element and compacting edge is adjustably positioned above the surface being treated and is attached to the casing to mechanically move therewith so as to compact the cementitious material as it is extruded from the casing upon mechanical actuation thereof. Finishing units comprising a plurality of finishing plates are activated into compressive engagement with the previously laid layer due to its down steam disposition relative to the outlet of the distributor casing. Thus the material can be distributed, applied and finished in a continuous sequence of operative steps employing the subject apparatus.

An applicator and distributor assembly of the type primarily designed to apply discontinuous pervious cementitious material over a given surface area, said assembly comprising:

a support frame including a leading and a trailing portion, running gear movably connected in supporting engagement to said frame and disposed in movable engagement with the surface being treated, a distributor casing mounted on said support frame in communicating relation to the treated surface and including a substantially elongated configuration extending transverse to the direction of assembly travelled over and along a length of surface area being treated, said distributor casing is pivotally attached to said support frame and movable in a displacable manner continuously during distribution of the cementitious material, whereby the material within said distributor casing is shocked to aid flow from said distributor casing, displacement means secured to said support frame and disposed in continuous periodic interruptive contact with said distributor casing, said displacement means disposed and structured for displacing movement of said distributor casing upon each periodic contact therewith, a casing outlet means formed in lower portion thereof in spaced above relation to the surface being treated, said displacement means is rotatably mounted on said support frame running gear and in continuous periodic interruptive engagement with said distributor casing, said distributor casing pivotally mounted for periodic displacement aiding flow of the cementitious material from said distributor casing through said casing outlet means, finishing means disposed substantially adjacent a trailing portion of said assembly and disposed adjacent said casing outlet means and down stream thereof in direct engageable relation with cementitious material flowing from said distributor casing through said outlet means, said finishing means movably secured to said support frame in compressing engagement with the layer of material disposed on the surface area.
