The shoveling hand cart apparatus is a material handling apparatus designed to provide an apparatus that will allow the user easy loading of bulky and heavy items into a wheeled bin by having an open end at or near load/ground height which aids in shoveling/scooping loads in much the way a hand truck operates on boxed loads and allows the user to easily transport contained and loose loads in a bin, and then dump, shovel or slide out the contents of the bin. The shoveling hand cart apparatus is comprised of a handle that has a significant vertical portion prior to the portion that is positioned along the upper part of the sides of the bin in order to permit the operator to work in a comfortable position. The holding area or bin of the cart has a rear arcuate wall and two sides with an open front section. The sides have a vertical dimension that is greater at the area adjacent to the rear arcuate wall and slopes as it goes forward to a smaller vertical dimension. A set of large rear wheels is positioned at the convergence of the sides and the arcuate rear arcuate wall. A set of smaller wheels is positioned at the frontal area of the sides. The design allows the heavy or bulky material to be loaded or unloaded through the open front section of the apparatus.

A humidifier as defined in claim 1, wherein said hygrometer comprises a humidity sensitive element and said display comprises an indicating needle coupled to said humidity sensitive element for providing a visual display that said wick requires replacement. 3. A humidifier as defined in claim 2, wherein said humidity sensitive element is a metallic coil. 4. A humidifier as defined in claim 1, wherein said display includes indicia to provide visual indication that said reservoir is empty. 5. A humidifier as defined in claim 1, wherein said hygrometer includes: a label that is impregnated with a chemical that changes color as a function of humidity, said label having: a first region that is light in color and darkens when the exit-relative humidity of the airflow reaches a first predetermined value; and a second region that is light in color and darkens when the exit-relative humidity of the airflow reaches a second predetermined value, wherein one of said first region and said second region define a set of indicia to form said display. 6. A humidifier as defined in claim 1, wherein said hygrometer is an electrical type and said display is a liquid crystal type calibrated to indicate that the wick requires replacement when the exit-relative humidity of the airflow falls below a predetermined humidity. 7. A humidifier as defined in claim 1, further comprising a second hygrometer to measure the ambient-relative humidity and including a means for comparing said exit-relative humidity with said ambient-relative humidity for indicating when the wick requires replacement. 8. A humidifier as defined in claim 1, wherein the air outlet includes a grill and wherein said wick change indicator further comprises an attachment means for removably attaching the wick change indicator to the grill of the air outlet, the attachment means comprising at least one finger projecting outwardly from the wick change indicator for engagement with the grill. 9. A humidifier as defined in claim 8, wherein the attachment means includes at least one straight finger projecting outwardly from the wick change indicator and at least one resilient finger projecting outwardly from the wick change indicator at an angle with respect to the straight finger, the at least one straight finger and the at least one resilient finger forming an open resilient jaw for attachment to the grill. 10. A humidifier as defined in claim 9, wherein the grill of the air outlet comprises a plurality of slats, at least one of said slats being frictionally held by the open resilient jaw of the attachment member. 11. A humidifier as defined in claim 1, wherein the wick change indicator further comprises a retaining ring and a transparent cover attached to the retaining ring for housing the hygrometer and the display therein. 12. A wick change indicator for a humidifier having a reservoir for holding water, a wick element seated in the reservoir and an air outlet for providing a flow of air having an exit-relative humidity associated therewith into a room having an ambient-relative humidity, the wick change indicator comprising: a humidity sensing means positioned within the airflow for measuring the exit-relative humidity of the airflow; display coupled to the humidity sensing means for indicating when the wick requires replacem ent based upon the measured exit-relative humidity substantially reaching a predetermined value; and an attachment means for removably attaching the wick change indicator to the air outlet. 13. A wick change indicator as defined in claim 12, wherein the attachment means comprises at least one finger projecting outwardly from the wick change indicator for engagement with a grill of the humidifier air outlet. 14.
