Abstract

A curbing apparatus consisting of a manually operable wheeled vehicle for forming curb mix asphalt into a uniform curb. The vehicle carries a curb forming shoe with a hopper thereabove and a manually controlled shutter and plunger. The asphalt mix is loaded into the hopper. Operation of the shutter permits the asphalt mix to fall by gravity into the shoe. Operation of the plunger compacts asphalt mix in the shoe to form the mix into a section of desired curbing.

The vehicle carries a curb forming shoe with a PATENTEDJUHZZIQYE 35 5911 INVIL N I UR. JOHN VLAs/c CURBING APPARATUS SUMMARY OF THE INVENTION The curbing apparatus shoe is horizontally elongated with an opening at the top and at both ends thereof. The shoe is open at bottom and is positioned close to the ground or road. The hopper is disposed above the shoe and has a bottom opening in registration with the top opening of the shoe. A horizontal shutter is slidable back and forth between the openings. A vertical plunger supports one end of the shutter and extends to cover the inner cross-sectional contour of the shoe. A manually controlled linkage permits the shutter to be moved out of registration with the openings whereby the mix falls through the hopper into the shoe, the plunger having been positioned remotely therewith. Thereafter, operation of the linkage moves the shutter between the openings to block further loading of the mix. At the same time, the plunger is moved toward the rearward end of the shoe to compact the asphalt mix to form the desired curbing as controlled by the shape and size of the shoe. Wheeled means secured to the curbing apparatus and supporting the hopper permit the ap paratus to be moved from place to place.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIGS. 1 through 7, a curb forming shoe 10 extends elongatedly and horizontally, with sides 12 extending downward and outward, a top plate 14 which can be curved or flat with a top opening 18 therein and opposite open ends and bottom. A hopper 16 is open at the top and has a bottom opening in registration with the opening 18 in the top plate 14.

A horizontal shutter 20 is slidable back and forth in the area between the hopper l6 and shoe 10 to be moved in and out of registration relative to the opening 18. One end of shutter 20 is carried by the vertical plunger 22. A horizontal bar 24 is secured at one end to the plunger 22 at 23 and at the other end is pivotally secured to the lower end of the vertical portion 26 of a T-shaped member 25. The horizontal portion 28 of the T- shaped member is pivotally secured at 27 between the horizontally elongated parallel supports 30 secured to the hopper 16 at 29 and extends away from one end thereof. An inclined handle socket 32 secured to portion 26 intermediate its ends receives handle 34. As handle 34 is raised, the shutter opens and asphalt mix present in the hopper falls into the shoe 10. As the handle is pushed down, the shutter closes and the plunger is pushed into the mix to compact same to form a curb section 48.

The supports 30 each have a vertical sleeve 38 into which rotatable vertical shafts 40 extend to rotate a frame 42 supporting a wheel 44 freely rotatable about a horizontal axle. Handle guides 46 are secured to the forward end of each support 30.

Should the curb section 48 need horizontal reinforcing rope or metal rods or the like, elongated sections of same can be manually introduced through the openings 50 in the plunger 22 prior to compacting.

The device described above can be used in the following manner.

A chalk line should be drawn to either left or right side of proposed curb and used for a guide line. The pavement surface should be clean and dry before laying the curbing. Also a light tack coat of liquid asphalt in thin streamers should be used to aid in bonding new curbing onto the already existing pavement.

The curbing apparatus should be sprayed with fuel oil inside of hopper l6, shoe l0 and on the plunger 22 before and after use. If sticky material is used, heat may be applied to the shoe, hopper and plunger. This will insure smooth operation of the curbing apparatus and final smooth surface finish on the new curbing.

The curbing apparatus is set at the starting point with the slanted rearward end 13 of the forming shoe at the point of beginning of the proposed curbing. With the hopper loaded to be approximately one-half full, the plunger handle 34 is raised and material will drop into the shoe. When the plunger handle 34 is pressed down, it will compact to form the desired curbing. A shovel can be initially placed over the end 13 of the shoe 10 to act as a stop to compact the initial beginning of the curbing. Upon compacting with the handle 34 and, when the rear end 13 of the curbing apparatus starts to slightly lift, the apparatus will be caused to move forward with every stroke of the plunger handle. The pressure exerted on the handle 34 for compacting also moves the apparatus forward. The keeping of the hopper 16 full of asphalt material will aid in compaction. Compaction pressure can be increased if pressure is applied back on either handle guide 46 while the plunger handle 34 is pressed down. Also the making of short rearward strokes with the handle 34 but not to the full extent of the stroke will aid in compaction of the asphalt material. Compaction can be also increased by lowering wheels 44 by vertical shafts 40 until proper curb height is accomplished.

When approaching a turn or a radius in the curbing to be laid, the wheels 44 should be adjusted to desired are or curvature, and the curbing will be formed according to the desired curvature.

It is always best to spray the parts of the curbing apparatus with fuel oil when the desired curbing is finished or when stopping for any period of time to avoid difficulties as to hardened asphalt material in again using the curbing apparatus.

The curbing material may contain portland cement and more sand than other mixes depending upon what is desired.

While I have described my invention wit-h particular reference to the drawings, such is not to be considered as limiting its actual scope.

Having thus described this invention, what is asserted as new is:
