| 摘要 | A self contained, key operated, multiple station counting device suitable for use, for example, with a compacting device serving a number of users. Each user''s station is provided with first key actuated means by which the trash compactor is actuated to receive, and then compact, trash placed therein, while at the same time a counting means is actuated to show this use of the compactor. Each user''s station is further provided with second key actuated means by which a separate counter, restricted to its respective station, is actuated to show that the compactor was actuated from that station. In this way the total number of times the compactor is used during a given time period is recorded while at the same time this total is broken down to show how many such uses are attributable to each of the individual stations. | ||||||
| 权利要求 | 1. A system for counting the number of times a trash compactor is used and by whom including a trash compactor having a normally closed position and a first source of electricity for actuating said compactor; a counting device having a second source of electricity; a plurality of stations in said counting device; a pair of normally open first and second switches for each said station; actuating means at each station for closing and opening said first and second switches together, a first circuit connected to said second source and including all of said first switches; a relay in said first circuit having an operative connection to said first source whereby to control actuation of said compactor; a totalizer in said first circuit for counting the total number of times said relay is actuated; a plurality of like second circuits connected to said second source, there being a separate said second circuit for each said second switch; a plurality of counters, there being one said counter in each said second circuit for counting the number of times said relay is actuated from the selected said station; and a plurality of dissimilar keys, one for each said station, to engage the said actuating means at the said station selected; whereby when said selected key is turned to move said actuating means the said first and said second switches for the selected station are closed and said relay, said totalizer and the said counter for the selected station are actuated, actuation of said relay causing said compactor to open so that trash may be placed therein, said totalizer and the said selected counter each recording such actuation of the said relay and said compactor, and whereby when said key is turned to its original position the said first and said second switches for the selected station are open and said relay, said totalizer and the said counter for the selected station are deactuated, deactuation of said relay causing said compactor to return to its original closed position whereby to compact the trash placed therein when open. 2. The system of claim 1 including a pilot light in said first circuit. |
