Abstract

A curb forming apparatus for extruding a paving material such as asphalt or concrete to continuously produce an elongated curb, median strip or the like including a pair of longitudinally aligned auger means having oppositely directed spiral flights with a hopper selectively securable to one or the other means so that the curb can be extruded in either direction from the same side of the apparatus. A curb forming means is secured to the outlet of the selected auger housing and the front and rear wheels are reversible. A cover is provided for the unused auger for safety purposes.

Claims

1. A curb forming apparatus comprising, in combination, elongated frame means having first and second longitudinally spaced end portions;

hopper means having an inlet for receiving a material from which the curb is to be formed, and an outlet;

conveyor means including first and second elongated auger housing means carried by said frame means in longitudinally spaced, aligned relationship, each of said auger housing means having a generally upwardly opening inlet and a longitudinally opening outlet, said outlet of said first auger housing means being directed toward said first end portion of said frame means and said outlet of said second auger housing means being directed toward said second end portion of said frame means, first elongated auger means rotatably supported within said first auger housing means, and second elongated auger means rotatably supported within said second auger housing means, said first and second auger means having oppositely directed spiral flights; and

driving means carried by said frame means for rotating said first and second auger means;

curb forming means having an inlet, an outlet and elongated, spaced, longitudinally extending lower edges;

roller means carrying said frame means and adapted for rollingly supporting said apparatus on a surface to be provided with a curb;

cooperable securing means carried by each of said auger housing means and said hopper means for selectively securing said hopper means to one of said auger housing means with said outlet of said hopper means in communication with said inlet of said one auger housing means; and

securing means for selectively securing said curb forming means to said one auger housing means with said inlet of said curb forming means in communication with said outlet of said one auger housing means.

2. The apparatus of claim 1 wherein said driving means simultaneously and continuously rotates said first and second auger means in the same direction.

3. The apparatus of claim 1 further including an auger housing cover means, said auger housing cover means including securing means cooperable with said securing means on said auger housing means, whereby said inlet of the unused auger housing means may be covered.

4. The apparatus of claim 1 further including vertical adjusting means securing said frame meanS to said roller means for vertically adjusting said frame means relative to said roller means, whereby said longitudinally extending lower edges of said curb forming means may be juxtaposed to the surface to be provided with a curb.

5. The apparatus of claim 1 wherein said roller means includes front wheel means and rear wheel means, rear securing means for securing said rear wheel means to the end portion of said frame means juxtaposed to said one auger housing means, and front securing means for securing said front wheel means to the other end portion of said frame means.

6. The apparatus of claim 5 wherein said front wheel means includes a pair of laterally spaced, steerable front wheel members, and said rear wheel means includes a single rear wheel member.

7. The apparatus of claim 6 further including a rear frame extension carrying said rear wheel means, said rear frame extension being securable to the end of said frame means juxtaposed to said one auger housing means and positioning said rear wheel member in lateral alignment with said outlet of said curb forming means.

8. The apparatus of claim 6 further including brake means operatively associated with said rear wheel member, thereby providing control of the compaction of the curb-forming material in the event the apparatus is progressing down a hill.
