1. An applicator mechanism for applying a layer of particulate materials on a ground surface over which it is manually movable, said applicator mechanism comprising:
- (a) a carriage including wheel means for manual manipulation in a forward direction along an intended movement path by an operator;
(b) an upwardly opening hopper structure supportingly mounted on said carriage for receiving a supply of particulate materials, said hopper structure having an elongated materials dispensing slot formed in the bottom thereof which is disposed to extend transversely of the intended movement part of said carriage;
(c) means on said hopper structure for selectively varying the length and width dimensions of the opening defined by the materials dispensing slot of said hopper structure to control the flow of particulate materials therethrough; and
(d) said wheel means of said carriage being disposed in angularly downwardly and rearwardly spaced relationship with respect to the materials dispensing slot of said hopper and in substantially full ground surface engaging contact transversely of the intended movement path of said carriage for rolling over the materials dispensible from the materials dispensing slot when said carriage is moved forwardly along the intended movement path thereof.

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.

5. An applicator mechanism for applying a layer of crushed rocks or other particulate materials on a surface over which it is manually movable, said applicator comprising:
-
(a) a wheeled carriage for manual manipulation in a forward direction along an intended movement path by an operator; (b) an upwardly opening hopper structure supportingly mounted on said wheeled carriage for receiving the supply of crushed rocks, said hopper structure having an elongated rock dispensing slot formed in the bottom thereof which is disposed to extend transversely of the intended movement path of said wheeled carriage; (c) means on said hopper structure for selectively varying the length and width dimensions of the opening defined by the rock dispensing slot of said hopper structure to control the flow of crushed rocks therethrough; (d) an elongated beam means disposed to lie transversely of the intended movement path of said wheeled carriage and having a portion which faces forwardly and an opposite portion which faces rearwardly, said beam means having said hopper structure mounted thereon and being disposed so that the elongated rock dispensing slot of said hopper structure opens onto the forwardly facing portion of said beam means; and (e) wheel means mounted on said beam means so as to extend angularly and downwardly from the rearwardly facing portion thereof. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. An applicator mechanism for applying a layer of particulate materials such as crushed rock on a surface over which it is manually movable, said applicator mechanism comprising:
-
(a) a wheeled carriage for manual manipulation forwardly along an intended movement path; (b) an upwardly opening hopper on said wheeled carriage for receiving the supply of crushed rocks, said hopper having an elongated rock dispensing slot formed in the bottom thereof which extends transversely of the intended movement path of said wheeled carriage, said hopper including, I. a planar front wall extending substantially upwardly from the rock dispensing slot thereof, II. frame means in coplanar spaced relationship with the forward surface of said front wall to provide a space therebetween, III. first gate means in spaced relationship between said front wall and said frame means and slidably movable toward and away from the rock dispensing slot of said hopper, said first gate means including a plurality of individually movable plates in side-by-side relationship with each of said plates having means for selective and individual movement thereof; and (c) second gate means including an elongated plate in engagement with the forwardly facing surface of said frame means and disposed in coextending relationship with the rock dispensing slot of said hopper, said elongated plate slidably movable toward and away from the rock dispensing slot of said hopper, said second gate means further including, I. guide brackets on the opposite sides of said front wall for retaining the opposite ends of said elongated plate and guiding the movements thereof, II. means connected to said elongated plate for movement thereof. - View Dependent Claims (15, 16, 17, 18, 19, 20)
