7 Claims. (Cl. 133--3) This application is a division of application Serial No. 798,264, filed March 9, 1959, now Patent No. 3,147,839.
This application relates to coin processing devices. More particularly the invention disclosed herein comprises a new and improved coin sorting machine.
My invention is particularly suited for use by such organizations a telephone companies, transit authorities, vending machine operators, banks, parking meter operators, etc. which handle large quantities of coin. At the present time such organizations authenticate and count coins either manually or semi-automatically which are very slow and tedious processes. Typically, coins from telephone pay stations are processed by telephone companies in the following manner. The coins are removed from the telephones in individual boxes which are carried to a central accounting office. At these offices, the boxes are individually opened, and their contents spread out on small tables and inspected manually to separate the counterfeit from the authentic coins. Thereafter, the authentic coins are counted by machines provided for thi purpose. Each telephone station must be credited with the dollar value of the authentic coins received by it so that the proprietor of the premises may receive his commission.
In the telephone system, my invention may be used in several ways. As a portable assembly, it may be taken to the site of each station and coins removed from the individual telephones may be proved and counted at or adjacent the premises. Alternatively, the assembly may be located at the central accounting ofiice and receive the contents of the individual boxes as they are brought to the accounting office from the separate stations. the use of my assembly, individual handling of the coins may be totally eliminated even to the extent of making the bookkeeping entries and drawing the lease or commission checks to the proprietors where the stations are located. This completely automatic handling is made possible because the machine may readily be connected to a conventional punch card process with no intermediate manual steps.
My portable assembly may also be used to collect coins from parking meters in a manner similar to that described above in connection with the removal of coins from individual telephone stations. For this purpose, a pick-up system is provided which is adapted to extract coins from parking meters and feed them automatically into the coin handling machine. This is carried out in a manner which is in effect pilfer proof.
My invention includes variou subassemblies which may be arranged in various orders depending upon the particular application for the device. The subassemblies include a pick-up device for introducing coins to the assembly, a sorting mechanism for separating coins of various denominations according to size, a proving device for determining the authenticity of the coins of each denomination, a device for separating authentic but multilated coins from those in good condition, and a counting mechanism for totaling the coins of each denomination and those rejected as mutilated, all shown in my patent 3,196,887 Patented July 27, 1965 application Serial No. 798,264 filed March 9, 1959, now Patent No. 3,147,839 dated September 8, 1964.
Obviously, the various subassemblies may be used in different combinations. For example, the portable assembly used to collect coins from telephone stations and parking meter would include a pick-up device for introducing coins to the unit, a sorter for separating the coins of different denomination received by the meters or telephone stations, provers for testing the authenticity of the coins of each denomination received, and the counting mechanism for totaling the value of the coin received. Banks may have several assemblies each one consisting of a sorter, a single prover for the denomination of coin being handled, a mutilated coin rejector, and a counter.
My coin sorter will be better understood and appreciated from the following detailed description, read in connection with the accompanying drawing, in which:
FIGURE 1 is a fragmentary view partly in section of the coin sorting subassembly;
FIGURES 2-4 are fragmentary views in perspective illustrating different cylindrical forms which may be used in the sorter of FIGURE 1;
FIGURES 5 and 6 are cross sectional views taken along section line 55 of FIGURE 4 showing successive positions of a coin sorted by the cylinder;
FIGURE 7 is still another embodiment of cylinder which may be used in the sorter of FIGURE 1;
FIGURE 8 is an enlarged detailed view of the cylinder in FIGURE 7;
FIGURE 9 is a cross sectional view taken along the section line 9-9 in FIGURE 8; and
FIGURE 10 illustrates a modification of the cylinder or drum shown in FIGURE 7.
The sorter illustrated in FIGURE 1 is adapted to separate coins of all denomination. That is, pennies, nickels, dimes, quarters and half-dollars may be handled by it. In FIGURE 1, the mechanism includes five concentrically mounted drums 70, 71, 72, 73 and 74 secured together at one end 75 by a web or similar 'means (not shown). The five concentrically mounted drums are rotated together about the common axis by a belt 76 which extends about the outer drum 74. The belt 76 is in turn driven by a motor 77 and its pulley 78. The relative diameters of the pulley 78 and the outer drum 74 provide the speed reduction necessary. Obviously, any other arrangement may be used to impart rotation to the drums.
The five concentrically arranged drums are specifically designed to separate the diiferent denominations of coin, that is, pennies, nickels, dimes, quarters and half-dollars. All but the outer drum 74 are covered with a lattice of perforations and the perforations in each drum are sized to pas all but the largest size of coins fed to it.
Coins are introduced into the drum assembly through a hopper 79 which terminates at the inner drum 70 at the end 75. The common axis of the drums is somewhat inclined, being lower at the end 80 and coins fed into the rotating drums will move by gravity from the hopper 79 toward the end 80.
The perforations 81 formed in the drum 70 are large enough to pass pennies, nickels, dimes and quarters but are insuflicient in size to allow half-dollars to pass through them. Thus, half dollars introduced into the drum 70 by the hopper will be carried by gravity to the end 80 of the assembly and slide down the chute 82. Similarly, the drum 71 is covered with openings 83 which will not pass quarters but are large enough to pass pennies, nickels, and dimes. The holes 84 in drum 72 will not pass nickels, but will allow pennies and dimes to fall into the drum 73. The holes 85 in drum 73 will retain pennies but will allow dimes to pass into the outer drum 74. The drum 74 is imperforate, and, therefore, all coins which pass to it,
9 namely, dimes and small slugs will be discharged from it by the chute 86. It will be noted that drums 71-73 are also provided with discharge chutes 87, 88 and 89, respectively.
Although the outer drum 74 is illustrated and described as being imperforate, it should be understood that it also may be perforated to pass coins smaller than dimes to still another drum. In this manner, obviously small counterfeit coins may be separated from other coins which at least approximate the size of authentic coins.
The orientation of the perforations and the drums may take any of several forms. Various forms of each are suggested in FIGURES 2-10. In FIGURE 2, it will be noted that the holes 90 are aligned both longitudinally and circumferentially about the drum while in FIGURE 3, the holes 91 are arranged in staggered circumferential rows to increase their density. As between the embodiments of FIGURES 2 and 3, the latter is preferred, for obviously, a drum with such an arrangement will have a greater capacity.
In FIGURES 4-6, another embodiment of the drum is shown. In this embodiment, the drum is formed as a polygon rather than round in cross section and the openings or holes 92 lie on the corners 93 of the polygon. That is, the transverse diameters of the openings with respect to the axis of the drum are coincident with the joints or corners of adjacent surfaces. The advantage of such an arrangement is shown in FIGURES 5 and 6. While in the embodiments of FIGURES 2 and 3, a coin must drop through the openings 90 or 91, that is, its sides must in effect align themselves with the periphery of an opening. As the coin slides over the inner surface of the drum in the embodiment of FIGURES 4-6, a coin may slide out of the drum through the openings 92 without a change in its direction of motion relative to the drum. This action is suggested in FIGURES 5 and 6.
While each of the embodiments of FIGURES 2-4 are adequate to handle the sorting operation in most applications, it will be appreciated that difficulties may occur when a great volume of coins are to be sorted. When great numbers of coins are contained within a single drum, as the drum rotates, the coins pile up on one another at the lowermost part of the drum and only the coins which lie against the surface of the drum have an opportunity to pass through the openings to the next outer drum. To avoid this difliculty, a tumbling action may be introduced to distribute the coins more evenly about the inner surface of the drum and avoid particular coins from riding on the top of a pile throughout the sorting action. In the embodiment of FIGURES 7-10, this tumbling action is accomplished by providing the cross section of the drum 94 with a saw tooth configuration. Note that the arrow 95 in FIGURE 7 suggests the direction in which the drum turns. The leading side 96 of each tooth 97 serves as a support to carry the coins up the side of the drum. When the supporting surface 96 of the folds in the drum which define the saw tooth cross section become inclined in a downwardly direction, toward the center of the drum 94, the coins will fall or slide off these surfaces and the tumbling action results. Thus, coins are not allowed to build up on top of large coins or remain on the top of piles of coins but are continuously churned by the tumbling action.
It will be noted that the openings 98 formed in the drum are intersected by the bases of the leading sides 96 of the saw tooth sections and thus, the coins are allowed to slide out of the openings in the manner suggested in FIG- URE 9. It will be appreciated that this action is substantially-identical to that illustrated in FIGURES 5 and 6.
In FIGURE 10, an additional modification is suggested. Adjacent the low side 99 of each of the circumferential rows 100 of perforations 98, ribs 101 are formed which retard the longitudinal travel of the coins in the drum. These ribs which lie immediately adjacent the edges of the circumferential rows 100 of the holes align the coins with 4 the perforations 93. As a result, those coins which are of a size to pass through the openings will be directed to the openings to hasten the sorting action.
From the foregoing description, those skilled in the art will appreciate that numerous modifications may be made of the inventions disclosed without departing from the spirit of my invention. Therefore, I do not intend to limit the breadth of my invention to the specific embodiments illustrated and described, but rather, it is my intention that the scope of my invention be determined by the appended claims and their equivalents.
