[a d W A O/F/VEVS United States Patent 3,064,888 COUNTIL\TG MARKER Robert L. Van De Mark, 700 Brown St., St. Clair, Mich. Filed Oct. 26, 1960, Ser. No. 65,032 2 Claims. (Cl. 235-92) This invention relates to a counting marker and refers more particularly to a marking and counting mechanism which is adapted to be utilized for production and inventory controls.
Previously, when an inventory or production count was being conducted, it was required that the person taking the inventory actually mark the items or articles and make a mental note as to how many articles were counted. After a certain number of articles had been marked and mentally recorded, as an example fifty, the person would make a permanent record thereof and would start over again mentally counting the articles being inventoried. This procedure would be repeated until the entire inventory or production count had been completed. Some persons mark and simultaneously mentally record the articles regardless of the number of articles to be counted.
From the above description, it is readily apparent that the prior art method is subject to many mental errors, particularly when a large number of articles are to be counted over a long period of time. With the marking and counting mechanism described herein, the need for continuous mental efiort or memory on the part of the person utilizing the mechanism has been substantially reduced.
The invention is characterized by its ability to clearly identify the materials Or articles counted and to keep an accurate total of the materials or articles counted. Such a mechanism eliminates certain time losses, fatigues and frustrations which are inherent in the prior art method.
It is an object of the present invention to provide a marking and counting mechanism which includes a marker and a counter remote from the marker.
It is another object of the present invention to provide a combination marking and counting mechanism which will place a mark on the articles inventoried and in addition thereto make a permanent record of the number of articles marked.
A further object of the present invention is to provide a marking and counting mechanism comprising a marker, a counter remote from said marker, actuating means for the counter and control means for the aforesaid counter actuating means comprising a movable member on the marker which is actuated by marking pressure applied to the marker and a flexible connection between the movable member and the counter actuating means.
Another object of the invention is to provide a combination marking and counting mechanism comprising a marker, a counter remote from said marker, electrical actuating means for the counter and a switch for the aforesaid counter actuating means comprising a movable contact member on the marker actuated by marking pressure applied to the marker and a flexible electrical conductor between the movable contact member and the counter actuating means.
A still further object of the invention is to provide a simplified, low cost marking and counting mechanism of the aforementioned type having certain advantages contributing to simplicity, efliciency, reliability, accuracy and long life.
Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawing illustrating a preferred embodiment of the invention, wherein:
FIGURE 1 is a front elevational view, partly in section, of the marking and counting mechanism.
FIGURE 2 is a sectional view FIGURE 1.
FIGURE 3 is a sectional view taken on line 33 of FIGURE 1.
The combination marking and counting mechanism is represented by the numeral 10 and comprises a plurality of components including a marking device 12, an electrical switch 14, a source of electrical energy 16, an electrically actuated counting mechanism 18, and a flexible conductor 19.
The electrically actuated counting mechanism 18 is of the conventional type and includes actuating means within the housing of the mechanism 18 for advancing the counting mechanism 18 one digit each time marking pressure is applied to the marking device 12. Although four banks of numerals are shown in FIGURE 1, it should be understood that any number of banks may be utilized.
The marking device 12 includes a cylindrical housing or holder 20 which is adapted to carry a longitudinally movable marking instrument or pen 22. Pen 22 includes an ample supply of ink, valve actuated under the control of the operator, or other marking material designated by the numeral 23. The instrument or pen 22 is disposable and different colored marking instruments or pens are available to facilitate or aid in the taking of an inventory. A different colored pen may be used to make each inventory count distinctive so that the articles which display ink spots of more than one color are quickly known as slow moving items.
The holder 20 has a threaded cap 24 at one end thereof which has mounted therein the electrical switch 14. The switch 14 includes a pair of electrical contacts 25 and 26. The electrical contacts 25 and 26 are suitably connected to the inner walls of the cap 24 by rivets.
The flexible electrical conductor 19 extends outwardly from the outside wall of the cap 24 and has a pair of electrical leads 30 and 32 therein which are adapted to be connected on one end thereof to the contacts 25 and 26 respectively.
The source of electrical energy 16 may take the form of a battery 34. The battery 34 is interposed in the electrical lead 30 between the actuating means of the counting mechanism 18 and the contact 25. The other electrical lead 32 connects the contact 26 with a terminal provided on the electrically actuated counting mechanism 18.
FIGURE *1 shows the marking device 12 in its free state so that the contacts 25 and 26 are open with contact 25 in engagement with the inner end of the pen 22. When marking pressure is applied to the marking pen 22, the marking pen 22 is depressed in the holder 20 to move the contact 25 into engagement with the other contact 26, thereby completing the electrical circuit. Once the switch 14 is closed, the electrically actuated counting mechanism 18 is advanced one digit in the conventional manner. When the marking pressure is released from the pen 22, the contact 25 returns the pen 22 to its original position in the holder 20.
The battery 34 and the counting mechanism 18 are mounted remote from the marking instrument 12 so that a person taking an inventory is permitted to take hold of the marker 12 and move freely within a given area due to the flexible conductor 19 without having to carry the electrically operated counting mechanism 18 and the battery 16. The leads 3() and 32 may be of any length to accomplish this objective.
The marking holder 20 provides a convenient handle for utilizing the device 10 in operation. The marking device 12 is disassembled with the removal of the cap 24. The old pen 22 is removed and the replacement pen installed in a few seconds.
This invention has provided a simple, economical,
taken on line 2-2 of handy, and light-weight accurate mechanism for simultaneously marking and electrically counting articles to be inventoried.
The drawing and the foregoing, specification constitute a description of the improved counting marker in such. full, clear, concise and exact terms as to enable, any person skilled in the art to practice the invention, the scope of which is indicated by the appended claims.
