Abstract

A manually manipulatable applicator mechanism for applying and embedding crushed rocks on selected areas of a paved surface. The mechanism includes a first gate structure by which an operator can vary the width dimension of the pattern of applied rocks and a second gate structure for controlling the quantity of rocks applied by the mechanism and thus controlling the thickness of the pattern of applied rocks.

6. An applicator mechanism as claimed in claim 5 wherein said means comprises:

(a) first gate means on said hopper structure adjacent the hook dispensing slot thereof and including a plurality of plates which are individually and selectively movable relative to the rock dispensing slot of said hopper structure for adjustably varying the length dimension of the opening defined by the rock dispensing slot; and

(b) second gate means on said hopper structure adjacent the rock dispensing slot thereof and adjustably movable in a direction transverse of the slot for adjustably varying the width dimension of the opening defined by the rock dispensing slot.

7. An applicator mechanism as claimed in claim 5 wherein said wheel means extends transversely of the intended movement path of said wheeled carriage for rolling over the crushed rocks dispensible from the rock dispensing slot of said hopper structure when said wheeled carriage is moved forwardly along the intended movement path thereof.

8. An applicator mechanism as claimed in claim 5 wherein said wheel means includes a plurality of juxtaposed wheels which are in substantially axial alignment with respect to each other and extend in substantially parallel relationship with respect to said beam means so as to transversely span the intended movement path of said wheeled carriage.

9. An applicator mechanism as claimed in claim 5 and further comprising:

(a) said hopper structure including a planar front wall which extends substantially upwardly from the rock dispensing slot thereof;

(b) frame means in coplanar spaced relationship with respect to the forwardly facing surface of the front wall of said hopper structure to provide a space therebetween; and

(c) first gate means in the space between the front wall of said hopper structure and said frame member and slidably movable toward and away from the rock dispensing slot of said hopper structure, said first gate means including,

I. a plurality of individually movable plates in side-by-side relationship,

II. means connected to each of said plurality of plates for selective and individual movement thereof.

10. An applicator mechanism as claimed in claim 9 wherein said means connected to each of said plates comprises:

(a) a chain having one end attached to the forwardly facing surface of one of said plurality of plates and extending upwardly therefrom to place the other end thereof proximate the open upper end of said hopper structure; and

(b) an upwardly opening yoke mounted at the open upper end of said hopper for demountably receivingly holding a portion of said chain therein.

11. An applicator mechanism as claimed in claim 9 and further comprising:

(a) second gate means including an elongated plate in engagement with the forwardly facing surface of said frame means and disposed in coextending relationship with respect to the rock dispensing slot of said hopper means, said elongated plate slidably movable toward and away from the rock dispensing slot of said hopper structure;
