COIN COUNTING DEVISE Albert N. Wagner, Cary, Ill.
Application September 8, 1938, Serial No. 228,883
(Cl. 13S-1) 8 Claims.
The present invention relates to improvements in means for receiving and automatically counting coins of given denominations and has for its main object to provide a very simple, cheap, efcient and portable device of this character which may be made in sizes to receive coins of respectively different denominations.
A further object of the invention is to provide a coin receiving and counting device which will receive and retain only the predetermined number of coins desired to be received therein for purposes such as subsequently disposing said coins in conventional coin wrappers used by banks etc. etc.
A very essential object of the invention is to provide a device of the character dened, which may be held in the hand in a substantially predetermined position ior the reception of coins in its upper end portion, to effect the automatic counting and positioning of said coins in a substantially stacked relation, regardless of the variations in thicknesses of the coins of the denomination for which the particular device is adapted.
Other objects of the invention will be readily understood from or are particularly set forthin the following specification.
A suitable embodiment of the invention is illustrated in the accompanying drawing, wherein:
Fig. l is a perspective view of a coin receiving and counting device constructed in accordance with the invention.
Fig. 2 is a central vertical longitudinal sectional view of the same.
Figs. 3 and 4 are, respectively, fragmentary detail sectional views on an enlarged scale taken on the lines 3 3 and 4 4, respectively of Fig. 2.
Fig. 5 is a fragmentary detail vertical longitudinal sectional view of the lower end portion of the device as shown in Fig. 2.
The device of the present invention comprises a tube I, composed of a suitable material, which is substantially elliptical in cross section, the inner largest diameter of said tube being substantially equal to that of the coins of a given denomination which the tube is intended to receive.
In the instance illustrated we will assume that the device is adapted to receive the coins commonly known in this country as nickels The longer diameter of the tube I is slightly greater than the diameter of the coin of the denomination for the reception of which the tube is designed. The shorter diameter of the tube is such, in the instance illustrated, that it is equal to. the vertical leg of an equilateral right angled triangle, the hypotenuse of which is of a length equal to the longer diameter of said tube. This is further explained hereinafter.
The tube is adapted to be normally disposed at an angle of 45 degrees, more or less, to a horizontal plane and in such position that the vertical piane of the axis of the tube is coincident with its shortest diameter and' is perpendicular to the said horizontal plane.
Along the upper wall of the tube, when so positioned, and disposed in intersecting relation to the vertical plane of the axis of said tube, there is provided a series. of spaced apart recessesv 2 extending transversely of the longitudinal axis of the tube with the walls of said recesses disposed at angles of degrees to each other and at an angle of 45 degrees to the axis of the tube. This specified relation of the walls of said recesses to the longitudinal axis of the tube may be changed and Varied to an appreciable extent, but for purposes of illustration and description it is assumed that angles of 90 degrees and 45 degrees, respectively, are selected.
By reference to Fig. 5, wherein the recesses 2 are shown most clearly, it will be noted that each recess has a top wall 3 disposed in a horizontal plane and which is of a length equal to the normal thickness of a coin 4, such as a nickel, adapted to be received within said tube I. The vertical walls 5 of said recesses` are vertically disposed and are spaced equidistantly from each other throughout the length of the tube. The Wall portion 6 of the tube I diametrically opposed to the recesses 2, is smooth and affords support for the edges of the nickels 4 shown, which, when inserted into the tube, slide down along the peripheral wall thereof until the lower edge of the first coin strikes the closure of its lower end and becomes substantially vertically disposed with its upper edge opposed to the lowermost wall 3.
In the instance illustrated, the lower end of the tube is cut away at an angle of 45 degrees to the axis of the tube. A closure gate receiving and guiding member 'I is suitably secured by means of flanges or projections 3 to the side wall portion of the tube I adjacent its lower end and is equipped with L-shaped vertical side ilanges 9 which provide grooves to receive the side edge portions of the closure gate Il); the latter being equipped with a digitally engageable iiange II at its upper edge for digital manipulation to open and close the discharge end of the tube for effecting discharge by gravity of the coins disposed within the same.
, are approximately parallel.
Mounted upon the upper end portion of the tube I is a funnel I2. The latter being equipped with a discharge opening I3 leading into the tube, said opening being smaller than the open end of the tube opposed thereto. Said opening vis bordered by a ange I4 which telescopically receives the upper end portion of the tube I and which is suitably secured thereto.
In the instance illustrated, or as would be true of the structure when designed to receive nickels, the total number of the upper walls 3 of the recesses 2 will be forty, with the lowest one of said walls 3 disposed immediately adjacent the gate I0. The uppermost wall 3 of the series is disposed immediately adjacent the upper extremity of the tube I. Adjacent to the portion of the wall of the tube equipped with said recesses 2, there are provided `slots I5 through which the edges of the coins are visible. A graduated scale is imprinted or otherwise impressed upon the exterior surface of the tube I as shown in Fig. 1 to indicate the number of Vnickels contained within the tube which are vis- -ible through said slots I5.
The lowermost portion I6 of the wall of the lfunnel I2 as shown in Fig. 2, is preferably bowed inwardly to the point at which said wall meets the shoulder portion I7 extending downwardly to meet the said ilange I4.
In use the device is held in substantially the position shown in Fig. 2 and nickels may be dropped into the funnel I2 and when delivered into the tube, will be positioned to slide along the end between the side wall portions Vthereof until the first of said coins strikes the said gate Said coin will then become disposed in contact and parallel with said gate I0 with its upper edge portion disposed closely adjacent to and Vopposed to the horizontal shoulder of the lower- The next succeeding coin will inst-mentioned coin, or, in the event that the rst coin should be slightly thinner than the Vsecond-mentioned coin, the latter will become very slightly angularly disposed relatively7 to the same with its upper edge portion abutting the lowermost vertical shoulder of the next lowermost recess 2 next behind the preceding coin. As each coin reachesthe lower limit of its travel within the tube, it will become substantially vertically disposed and the upper edge of each of said coins, whether of normal thickness or worn,
vwill become disposed in one of the recesses 2; itV being impossible, by reason of the cross-sectional -dimensions of the'tube, for any coin to become disposed in any other relation to other coins or to the recesses 2 than is clearly illustrated in Fig. 5.
As the coins slide downwardly in the tube, their side edge portions contact with the side wall portions of the tube with the faces of the coin disposed substantially parallel with the axis of the tube and at an angle of about fortyiive degrees to a vertical plane extending transversely of the tube and with which the gate of the latter and coins previously fed into the tube When the lower edge portion of the traveling coin strikes either the gate or a face of a previously inserted coin,
said lower edge will be projected downwardly, thus rotating the coin through a short arc about a horizontal axis disposed transversely of and in approximately intersecting relation to the axis of Vthe tube.
Following this short arc rotation of the coin, its movement becomes arcuate about the lowermost edge portion of the coin as a fulcrum until the upper edge portion of the coin is disposed in the recess 2 immediately behind that which contains the upper edge portion of the next preceding coin.
As the upper substantially horizontal wall of each recess 2 is the same width as the thickness of a new or unworn coin of the denomination for which the tube is intended, and the distance between said upper Wall and the substantially vertically opposed point in the lowermost wall portion of the tube is only very slightly greater than the diameter of a new coin of the said denomination, it follows that no recess 2 can receive the upper edges of two coins unless the latter are worn down to about half their initial thickness, but as such coins are never in circulation, the same being taken out of circulation as soon as their faces are so worn as to be unreadable, there is no danger of more than one coin being received for each recess 2. Experience has shown that even if a number of badly worn coins are fed successively into the tube they become progressively canted to a greater degree within the tube with their lowermost edge portions spaced less distance from the gate than the vertical shoulders of the corresponding recesses 2, but even in such extreme cases, the total number of coins capable of being received within the tube is limited to the number of horizontal shoulders of the stepped formation formed by the recess 2.
The elliptical cross sectional shape of the tube is very essential because of the canted position of the coins which renders necessary that the vertical diameter of the tube shall be slightly greater than that of the coins in the planes of the latter or in the planes parallel with the gate while the horizontal diameter must be slightly greater than the diameters of the coins. If the tube were cylindrical and of the last-mentioned iameter, then the stepped upper wall portion thereof containing the recesses 2 would be required to project inwardly from the adjacent parts of the tube a distance suicient to space the same an equal distance from the bottom or diametrically opposed portion of the tube, as is true of the elliptical tube. If this were not done the Vangularly disposed coins would not engage in the recesses 2.
The last vcoin of the entire number is disposed practically in such close proximity to the mouth of the funnel as to constitute a closure for the latter. The lower edge portion of said last coin will be disposed in overlapping relation to the shoulder I'I and regardless of how many relatively thin coins of the given denomination are fed into the tube, there will not be enough space between the uppermost of said coins and said shoulder I I to receive another coin of the said denomination.
In the instance illustrated, coins in excess of the number (forty) intended to be received within the tube, will remain disposed upon the lower wall of the funnel with the upper edge portion thereof overlapping the front substantially vertical wall portion of the funnel. When an excess number of coins is fed into the funnel, the tube may be inverted to discharge sai-d excess coins from the funnel without causing any of the predetermined number disposed within the tube -to be discharged. rIfhis is due to the fact that upon inverting the tube I, the pressure of the entire stack of coins is exerted against the upper coin ofthe tube to Vfirmly compress the same against said shoulder il, thus preventing said coinfrom being displaced or canted to become disengaged from the uppermost recess 2.
The coins are discharged by gravity very easily and quickly by opening the gate it, as will be obvious. f
