Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A sand or soil bagger comprising: a hopper for receiving loose sand or soil and the like; grate means for screening the sand or soil to promote a constant flow; a multiple of laterally spaced independent gate-controlled bagging chutes provided in the bottom of said hopper; and power actuated means on said hopper for constantly vibrating said hopper and grate means thereby maintaining a steady flow of said sand or soil to and through said bagging chutes as the gates therEof are opened for filling bags with said or soil and a platform suspended on said hopper beneath said chutes for supporting bags being filled with sand or soil from said chutes.
Claim 2
Dependent Claim
112 words
A sand or soil bagger comprising: a hopper for receiving loose sand or soil and the like; grate means for screening the sand or soil to promote a constant flow; a multiple of laterally spaced independent gate-controlled bagging chutes provided in the bottom of said hopper; and power actuated means on said hopper for constantly vibrating said hopper and grate means thereby maintaining a steady flow of said sand or soil to and through said bagging chutes as the gates therEof are opened for filling bags with said or soil and a platform suspended on said hopper beneath said chutes for supporting bags being filled with sand or soil from said chutes.
Claim 3
Dependent Claim
46 words
A bagger as recited in claim 1 wherein power driven auger means is provided near the bottom of said hopper for distributing sand or soil received from said hopper transversely of the latter whereby said bagging chutes will all be uniformly supplied with sand or soil.
Claim 4
Dependent Claim
78 words
A bagger as recited in claim 1 wherein detachable attachment means are provided for mounting said hopper on the rear end of a tiltable body of a conventional dump truck whereby a rearward upward tilting of said body deliver or soil gravitationally from said body into said hopper and wherein the vibration of said hopper and grate means is transmitted to said truck body facilitating the smooth discharge of sand or soil from said body into said bagger.
Claim 5
Dependent Claim
90 words
A detachable sand-or soil-bagging unit adapted for replacing the tailgate of a conventional dump truck, said unit comprising: a closed end portion forming at its base a sand or soil hopper when in position of use; a sand or soil grating about the end portion for preventing clogging; multiple manually controlled gated chutes projecting from said hopper; a spreader in said hopper fashioned in a manner to deliver sand or soil substantially evenly to said chutes; power means for said spreader; and means for vibrating the truck and bagging unit.
Claim 6
Dependent Claim
90 words
A detachable sand-or soil-bagging unit adapted for replacing the tailgate of a conventional dump truck, said unit comprising: a closed end portion forming at its base a sand or soil hopper when in position of use; a sand or soil grating about the end portion for preventing clogging; multiple manually controlled gated chutes projecting from said hopper; a spreader in said hopper fashioned in a manner to deliver sand or soil substantially evenly to said chutes; power means for said spreader; and means for vibrating the truck and bagging unit.
