Abstract
A sampling apparatus for taking a core sample of dense packed fibrous material including: (a) a generally cylindrical sampling tube open on its distal end, wherein the length of the sampling tube is greater than the sample length; (b) at least one exhaust port outside the sampling length adjacent to its proximate end; (c) a ram rod movable from the proximate end to the distal end of the sampling tube for discharging a sample from the sampling tube; and (d) a drive attached to the proximate end of the sampling tube for aiding in sampling.
Claims26
A rotary sampling apparatus for sampling the installed density of an insulative material installed adjacent to a building structure by obtaining a sample length, said apparatus comprising:
- (a) a generally cylindrical sampling tube open on its distal end, wherein the length of the sampling tube is greater than the sample length;
- (b) an end wall that has a surface approximately perpendicular to the longitudinal axis of the tube, the surface including at least one exhaust port outside the sampling length, said exhaust port adapted to both permit the unobstructed egress of air therethrough, and to exhaust air directly from the port into the ambient;
- (c) at least one serration on the distal end of the sampling tube, wherein the at least one serration is configured to cut into the installed insulative material and to prevent breaching the adjacent building structure;
- and
- (d) a drive attached to the proximate end of the sampling tube for aiding in sampling, wherein the drive includes a quick disconnect between the drive and the sampling tube.
A rotary sampling system for taking a sample length of dense packed fibrous material installed adjacent to a building structure, said system comprising:
- (a) a generally cylindrical sampling tube open on its distal end wherein the length of the sampling tube is greater than the sample length;
- (b) an end wall that has a surface approximately perpendicular to the longitudinal axis of the tube, the surface including at least one exhaust port outside the sampling length, said exhaust port adapted to both permit the unobstructed egress of air therethrough, and to exhaust air directly from the port into the ambient;
- (c) a ramrod movable from the proximate end to the distal end of the sampling tube for discharging a sample from the sampling tube;
- (d) at least one serration on the distal end of the sampling tube, wherein the at least one serration is configured to cut into the installed insulative material and to prevent breaching the adjacent building structure;
- and
- (e) a rotary drive attached to the proximate end of the sampling tube for aiding in sampling, the rotary drive including a motor.

- (c) a ram rod attachable to the sampling tube and movable from the proximate end to the distal end of the sampling tube for discharging a sample from the sampling tube;
- (d) a rotary drive attachable to the proximate end of the sampling tube for aiding in sampling, the rotary drive including a motor, and
- (e) at least one serration on the distal end of the sampling tube, wherein the at least one serration is configured to cut into the installed insulative material and to prevent breaching the adjacent building structure.
