/W E W 465N7- DEVICE FOR MEASURING COINS AND WRAPPING THEM IN ROLLS BACKGROUND OF THE INVENTION The present invention relates to a device for quickly and easily measuring a number of coins of the same denomination and wrapping them in rolls. The invention is particularly useful for any individual or small business establishment whose normal business transactions involve the handling of large numbers of coins. Heretofore, such individuals or business establishments have usually found it necessary to count the coins by hand, after which rolls of a specified number of coins are wrapped in paper wrappers by hand. Hand-counting of coins is tedious and time-consuming, and subject to error. Hand-wrapping the rolls of coins is slow and awkward until the individual has acquired a high degree of manual dexterity by long practice.

Machine counters and wrappers are available, and these are used by banks and large retail business establishments handling extremely large numbers of coins, but such machines are quite expensive, and are not economically justified for the smaller business establishment or individual whose volume of coins handled might amount to a few thousands per week instead of the tens of thousands handled by the average bank or large retail business.

SUMMARY OF THE INVENTION The primary object of the present invention is to provide a simple, inexpensive device that enables an individual to quickly and easily measure out coins into stacks of a predetermined number, and then wrap the stacks of coins with paper wrappers.

Another object of the invention in one of its embodiments is to provide a device of the class described which can be used to measure and wrap rolls of coins of several different denominations, which are all different from one another in their dimensions, by merely turning the device so that one or another of its several different sides face upwardly to receive the rolls of coins.

These objects are achieved in the present invention by providing a two-part device consisting of a cylindri- .cal tube and a roller device, said tube being open at one end to receive coins so that when filled to the top with coins of a specified denomination, it forms a roll con taining a predetermined number of coins. The tube, loaded with coins, is then placed on the device, where it is cradled between two parallel rollers, with a paper wrapper interposed between the rollers and the tube. The tube is centered between the two ends of the device by two opposed locating pins, one of which is stationary and the other spring-loaded. The springloaded pin passes through a hole in the center of the tube bottom, and passes over the end of the device to make a 180 turn downwardly and back'under the rollers, where it is attached to a spring. The tube has a lengthwise extending slot formed in one side and reaching to the hole in the tube bottom, and when the tube has been properly centered between the pins, it is withdrawn endwise over the spring-loaded pin. The slot in the tube allows the downwardly bent portion of the spring-loaded pin to pass freely along its length, from one end of the tube to the other. The roll of coins, now held between the stationary and spring-loaded pins, is revolved on the rollers, while the paper wrapper is wrapped around it. The wrapped roll is then removed from the device, and the ends of the paper wrapper are crimped down.

In a second embodiment of the invention, the device has parallel pairs of rollers on each ofits four sides, and stationary pins on each side, of different lengths, so that rolls of different denomination coins, which vary considerably in length, are each centered with respect to opposite ends of the device. Thus, the rolls are centered in their respective paper wrappers, while the wrappers are centered by the ends of the device. This embodiment of the invention is thus able to wrap coins of four different denominations without manually shifting the rolls of coins to center them on the paper wrappers. As in the first embodiment, separate tubes are required for the different coins.

Other objects and advantages of the invention will become apparent to those skilled in the art from the following detailed description of two illustrative embodiments thereof, with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of FIGS. 1-8 will be described first. The invention comprises a two-part apparatus consisting of a roll-wrapping device 10 and a coin-measuring and roll-forming tube 12. The tube I2 is cylindrical in shape and is open at the top end to receive coins ofa particular denomination. The inside diameter and length dimensions of the tube are such that coins of the specified denomination fit snugly, yet freely, within the tube, and when the tube is filled to the top, there will be an exact predetermined number of coins contained therein. Thus, for example, a tube for pennies would contain 50 coins; for nickles, it would be 40; for dimes, it would be 50; and for quarters it would be 40. These are the numbers of U.S. coins that are contained in standard bank rolls. Since rolls of these four coins are different from one another in diameter and length, there would be four different tubes for the four coins mentioned. Coins of other countries would have their own tubes 12 to measure them out into rolls of a specified number.

The bottom of the tube is formed by an inwardly projecting, annular shoulder 14, which defines a central aperture 16. The aperture 16 is connected by a short radial slot 18 to a lengthwise extending slot 20 formed in the one side of the tube, the purpose of which will become apparent hereinafter. The tube 12 is filled with coins 22, which come exactly to the top of the tube when the specified number of coins is contained therein. Thus, it is not necessary to count the coins one by one, and the tube can be filled as rapidly as the coins can be funneled into it. When the tube has been filled to the top, it is cradled between rollers on the rollwrapping device, as shown in FIG. 2.

The device 12 consists of a flat, rectangular base 24, having parallel

upstanding end plates

26 and 28. Extending between

end plates

26, 28 are two laterally spaced,

parallel rollers

30 and 32, each of which has bearing pins 34 at its ends, which are journaled in bearing sockets provided in the

ends

26, 28. Projecting inwardly from end plate 28 midway between

rollers

30, 32 and slightly above the latter is a stationary locating pin 36. At the other end of the device is an opposing spring-loaded pin 38, the free end of which is axially aligned with pin 36. The ends of

pins

36, 38 are positioned so that they engage the end coins in the tube 12 at about the center of the coins, pin 36 abutting against the top coin at the open end of the tube, and pin 38 pressing against the bottom coin in the tube, through aperture 16.

As best shown in FIG. 6, the spring-loaded pin 38 has the general shape ofthe letter J, and after passing over the top edge of end plate 26, bends downwardly in a 180 turn and becomes an elongated shaft 42 extending parallel to the axes of the

rollers

30, 32, midway between and somewhat below the rollers. The shaft 42 passes through a hole 44 in end plate 26, and enters a hollow tube 46, the ends of which abut against and are joined to

end plates

26, 28. Tube 46 is parallel to

rollers

30, 32 and somewhat below them, as best shown in FIG. 5.

Surrounding the shaft 42 is a helical compression spring 48, one end of which bears against the end plate 26, while the other end bears against the annular shoulder formed by an enlarged-diameter head 50 at the end of shaft 42. Spring 48 urges the shaft 42 to the right as viewed in FIG. 6, causing the pin 38 to press against the end of the roll of coins. Where the pin 38 passes over the top of end plate 26, the latter has an arcuate cut-out 52 to provide clearance for the tube 12 when the latter is removed endwise from the device, as shown in FIG. 3.

The manner of using the invention is as follows: Tube 12 is filled to the top with coins 22 of the same denomination, and the loaded tube is then laid down on the device 10 so that it is cradled between

rollers

30, 32, as shown in FIG. 2. The open end of the tube 12 faces toward end plate 28, and stationary pin 36 abuts against the top coin in the tube. Spring-loaded pin 38 passes through the aperture 16 in the bottom of tube 12, and bears against the bottom coin in the tube. Interposed between the

rollers

30, 32 and the tube 12 is a paper wrapper 54, the width of which is about a halfinch less than the inside distance between

end plates

26, 28, to allow for a certain amount of adjustment.

The tube 12 is now removed endwise from the roll of coins, as indicated by the arrow in FIG. 3. To do this, the tube is turned so that slot 20 is at the bottom. As the tube passes over the arcuate cut-out 52 in end plate 26, downwardly bent portion 40 of pin 38 passes through the short radial slot 18 in the tube bottom and then travels along the length of slot 20. Removal of the tube leaves the roll of coins resiliently confined between the locating pins 36 and 38, which center the roll with respect to the wrapper 54. One end of the paper wrapper 54 is now wrapped over the top of the roll of coins, and the roll is revolved on the

rollers

30, 32 to complete the wrapping. Upon completion of the wrapping, the roll of coins is lifted out of the device 10, and the ends of the wrapper are pressed down flat against the ends of the roll. Since the stack of coins is held together by the

pins

36, 38 while rolling the wrapper 54 around it, there is no manual dexterity required to hold the coins together with one finger of each hand, while simultaneously rolling the stack and manipulating the paper wrapper to carry it around the coins. As a result, even the most inexperienced and unskilled operator can wrap rolls of coins with speed and dexterity. Moreover, filling the tube 12 to the top with coins is a fast and extremely accurate way of measuring coins to ensure that the exact required number is contained in the roll, without counting the coins one by one. The entire apparatus for producing wrapped rolls of coins would, of course, include several tubes 12 of different inside diameters and lengths, in order to accommodate coins of different diameters and thicknesses, which are also packed in different numbers of coins to produce rolls of specified value.

Another embodiment of the invention is shown in FIGS. 9, 10 and 11, to which attention is now directed. This form of coin wrapper, designated generally by the reference numeral 10', has four sides that can be used to wrap rolls of coins of four different denominations. The device comprises two generally square end plates 26' and 28, which are fixed to opposite ends of a central tube 46 housing the spring and shaft 42' of the spring-loaded pin 38'. Disposed symmetrically around the tube 46 are four

parallel rollers

60, 61, 62 anok63, all of the same diameter and length, and all spaced the same distance apart from their adjacent rollers. The rollers are rotatably supported at their ends in the end plates 26', 28'. End plate 26' has four arcuate cutouts 52 in its four sides, and the spring-loaded pin 38' can be pulled out until its end clears plate 26', at which point the pin can be turned to any one of the four sides of the device, as desired. FlG. 10 shows the four positions of the pin 38 at A, B, C and D.

Projecting inwardly from the end plate 28' midway between each pair of rollers on the four sides thereof are four

stationary pins

36a, 36b, 36c and 36d. These pins are of varying lengths to accommodate the different lengths of coin rolls made with coins of different denominations. For example, a roll of 50 dimes is 2.60 inches in length; a roll of 40 quarters is 2.76 inches long; a roll of 50 pennies is 2.90 inches long; and a roll of 40 nickels is 3.00 inches long. in some cases the paper wrappers for all four coins are of the same width, and the wrapper is centered in the device by the end plates 26', 28', which are spaced apart only slightly more than the width of the wrapper. In order to center rolls of all four coins with respect to the end plates 26', 28,

pins

36a, 36b, 36c and 36d are made shorter or longer, as the case may be. Thus, the shortest pin 36a (for the longest roll, of 40 nickels) is made 0.20 inch shorter than the longest pin 36b (for the shortest roll, of 50 dimes), while the other two pins, 360 and 36d, are in-between lengths, one of them being 0.12 inches shorter than 36b, for rolls of 40 quarters, and the other being 0.05 inches shorter than 36b, for rolls of 50 pennies. The differences in length are exaggerated in the drawings for illustrative purposes.

The mode of operation of this embodiment of the invention is essentially the same as in the preceding embodiment, except that the device is turned to use the appropriate side for whichever coins are being wrapped. As in the previous embodiment, there would be four different tubes 12 for the four coins of different denominations, said tubes being of the exact length to contain the precise number of coins for a roll.

Both the coin wrapper 10 or 10' and tubes l2, l2 may be made of any suitable material, such as metal or plastic, and the shape of the several parts may differ from those shown. In the embodiment of FIGS. 9-11, the four pairs of rollers on the four sides of the device may be spaced apart different distances, if desired, to raise or lower the rolls of coins so that the center of the roll coincides with the center of the aligned pins 36', 38'.
