Abstract
Abstract An electric mortar spreader having a mortar container which is movable on anti-friction rollers and having a rearwardly inclined chute bottom. A pair of apertures through the rear wall of the container are gated to meter the flow of mortar therethrough. A lever is provided through the container operating two flapper valve elements selectively opening and closing ports through the bottom of the container and serving the apertures simultaneously. The lever is spring biased to close the ports on release of the lever and the lever actuates a normally open electrical switch. The electrical switch, when closed, permits electrical current to flow through a vibrator element secured beneath the inclined bottom of the container. The vibrator is suspended to impart oscillations to the container at the rear thereof and immediately beneath the floor or bottom adjacent the ports. A guide is secured to the side of the container and is selectively movable to depend below the lower line of block.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
71 words
A wheeled container having a chute therein and openings therethrough inclined to deliver mortar to the rear; valve means at said openings, at least one of said valve means operable to activate an electric circuit; a vibrator in said container beneath said chute and secured to said container imparting vibrations when said valve means are selectively opened; and an electric circuit actuated by opening said valve means and energizing said vibrator.
Claim 2
Dependent Claim
71 words
A wheeled container having a chute therein and openings therethrough inclined to deliver mortar to the rear; valve means at said openings, at least one of said valve means operable to activate an electric circuit; a vibrator in said container beneath said chute and secured to said container imparting vibrations when said valve means are selectively opened; and an electric circuit actuated by opening said valve means and energizing said vibrator.
Claim 3
Dependent Claim
161 words
A mortar spreader device comprising: a substantially rectangular wheeled container; a chute baffle forming an inclined bottom in said container and directing flow in said container toward one end thereof; a flow divider in said baffle dividing flow toward the corners of the lower ends of said chute; a pair of openings through the bottom of said container at the ends of said chute baffle and toward which said flow divider directs flow; valve closures simultaneously and tiltably actuated and in said container and movable toward and away from closing said openings; back openings at the lower corners of the rear of said container; valve gates on the exterior of said container slidable on the end of said container to selectively cover said back openings; and vibrator means secured to said container and actuated by opening said valved closures assuring uniform flow through said container and to and through said openings by transmission of vibration to the contents of said container.
Claim 4
Dependent Claim
161 words
A mortar spreader device comprising: a substantially rectangular wheeled container; a chute baffle forming an inclined bottom in said container and directing flow in said container toward one end thereof; a flow divider in said baffle dividing flow toward the corners of the lower ends of said chute; a pair of openings through the bottom of said container at the ends of said chute baffle and toward which said flow divider directs flow; valve closures simultaneously and tiltably actuated and in said container and movable toward and away from closing said openings; back openings at the lower corners of the rear of said container; valve gates on the exterior of said container slidable on the end of said container to selectively cover said back openings; and vibrator means secured to said container and actuated by opening said valved closures assuring uniform flow through said container and to and through said openings by transmission of vibration to the contents of said container.
Claim 5
Dependent Claim
23 words
The structure in accord with claim 1 wherein said vibrator means is secured to said end wall of said container intermediate said openings.
Claim 6
Dependent Claim
21 words
The structure in accord with claim 2 wherein said vibrator means is removably secured to said end wall of said container.
