SPECIFICATION forming part of Letters Patent No. 771,643, dated October 4, 1904.
' Application filed February 4, 1904. Serial No. 192,011. (No model.)
1'0 a6), LU/$0777, it may concern:
Be it known that 1, WILLIAM JOHNSON, a subject of the King of Great Britain, residing at Coventry, VVarwickshire, England, have invented certain new and useful Improvements in Change-Makers, of which the following is a specification.
My invention relates to improvements in apparatus for receiving a predetermined number of coins, usually of small values, from coin-freed gas-meters or the like and delivering them in exchange for a single coin of equivalent value; and my invention especially relates to improvements in the type of apparatus in which the operating-coins after performing their functions in the coin-freed machine pass directly from the said machine into the apparatus singly and after operating mechanism for indicating the number of coins introduced into the apparatus pass into a rotatable drum or box normally locked, but released by the insertion of a single exchangecoin of a value equivalent to its entire con-' tents and then rotated, whereby its contents are discharged.
I am aware that it is not new in apparatus for giving monetary change to employ a rotating box for receiving the operating-coins, nor is it new to employ the particularlocking and unlocking devices for the said box hereinafter described, such a construction being shown .in British Patent No. 6,366, dated March 5, 1902, a copy of which is on file in the United States Patent Oflice, and I do not claim these particular devices;- but the main features of my invention are a device for automatically registering the coins or the like as they enter the apparatus, an arrangement for preventing more than a predetermined number of operating-coins from passing into the apparatus, and an appliance for preventing the insertion of an exchange-coin until the apparatus contains the required number of operating-coins.
My invention also comprises means for rotating the box for receiving the operatingcoins and a device for bringing the indicator to its initial position when the apparatus is used for exchanging diiferent numbers of operating-coins for various exchange-coins of equivalent values.
In the accompanying drawings, which illustrate a construction of change-giving apparatus according to this invention, Figure 1 is a front elevation. Figs. 2 and 3 are side elevations of the same viewed as indicated by arrows in Fig. 1, and Fig. 4: is a side elevation of part of the mechanism for rendering the apparatus capable of exchanging two or more different numbers of coins for equivalent single coins.
Like numerals refer to like parts throughout the drawings.
The casing 2, which may conveniently be constructed of tinned iron, is provided with a coin-tube 3, havinga slott at the top, through which the operating-coins are introduced into the apparatus after having performed their functions in the coin freed machine. The passage through the tube 3 is large enough for the admission and passage of one operating-coin at a time, but not two or more side by side or overlapping. At the lower end the tube is inclined and is increased in bore to allow of the coins passing down the inclined part. Three apertures 5 6 7 are cutin the tube. A pallet 8, having a sloping hooked tooth 9 at its upper end and an inclined tooth 10 at its lower end, is balanced and pivoted, as on the pin 11 and bracket 12, so that the tooth 1O normally projects into or through the aperture 6 in the tube 3. A spindle 13 is arranged transversely of the casing 2 and tube 3 and is mounted in bearings 14L thereon. To this spindle is secured a wheel 15, having long teeth 16. These teeth are adapted to project into the aperture 7 in the tube 3to such an extent that one tooth and one tooth only can be acted upon at a time by the operating-coin and so that the operation of one coin will leave the next tooth ready to be operated upon by the next coin. The number of teeth on the wheel 15 is varied according to the number of operating-coins to be exchanged for one exchangecoin. Thus the apparatus illustrated in the drawings is provided with twelve teeth and is adapted to exchange twelve operating-coins for one exchange-coin. A bell-crank 17 18, pivoted, say, on the pin 11, is provided with astud 19 or the like on the end of the arm 17 and an inclined tooth 20 on the end of the other arm, 18. The stud 19 is adapted to engage the teeth 16 of the wheel and prevent the wheels rotating forward accidentally, the teeth preferably being inclined to give the stud 19 amore secure hold. Theinclined tooth is adapted to project into the slot 6 in the tube 3.
Fixed to the spindle 13, so as to revolve with the wheel 15, is a ratchet wheel or ring of ratchet-teeth 21, the shoulders of the teeth facing against the direction in which thesaid wheel 15 is adapted to revolve. An additional square-sided notch 22 is cut in the edge of the ratchet-wheel 21 at a point corresponding to the operation of the twelfth coin. A stud 23, carried by an arm 24, normally engages in the ratchet-teeth 21. The arm 24 is suitably pivoted, as by being secured in a disk 25, mounted freely on a fixed spindle 26. Below the wheels 15 21 is arotatable box 27, mounted on trunnions 28 and having an opening 29 like the box numbered 12 in the British patent above referred to. From one side of the box 27 projects a stud 30, which is adapted to act upon a long arm 31, secured in the abovementioned disk or otherwise adapted to move with the arm 24. On the spindle 13 is also fixed a drum 32, bearing a series of figures, such as 1 to 12, corresponding to the number of teeth 16 on the wheel 15, which are arranged according to the number of coins the apparatus is intended to register at a time. These figures are adapted to show one at a time through asight-hole in the front of the casing 2. Upon the spindle 13 is further fixed a disk 34, having a curved slot 35. A bellcrank 36 37 is pivoted, as at 38, and carries on its short arm 36 a stud 39, adapted to enter the slot when the proper time has arrived for exchanging the operating-coins in the box 27 for the single coin of equivalent value, such exchange being prevented at other times by the complete edge of the disk 34 obstructing the pin 39 if an attempt be made to move the said bell-crank. Thelongarm 37 is adapted to partly obstruct the slot 56, which is made in the casing for the introduction of the exchange-coin.
To one side of the box 27 is fixed a plate 43, having two recesses 44 45 and two bosses 46 47. A bolt 48, having a slot 49, is mounted freely on the trunnion 28. The bolt is normally impelled to the left of Fig. 2 by a spring, such as 50, threaded onto the pin 51, projecting from the bolt and engaging in a hole in the boss 46, the spring being compressed between the end of the bolt and the said boss. The engagement of the boss 47 with the slot 49 and the engagement of the pin 51 with the hole in the boss 46 confine the movements of the bolt 48 to a diametrical direction relatively to the plate 43. A bent lever 53 54 is pivoted to the casing at 55. The arm 54 forms a handle and covers a slot 56 in the casing. The slot 56 is for the introduction of the exchangecoin, and the bolt 48 is provided with a pocket 57 adapted to receive the said exchange-coin; but the depth of the pocket 57 is suitably less than the diameter of the said exchange-coin. A pawl 58, pivoted to the casing 2, normally engages in the recess 45 in the plate 43. A block 59, shaped concentrically with the trunnion 28, is fixed to the casing, and the top thereof projects under the end of the bolt 48 to an extent somewhat less than the difference between the total depth of the pocket 57 and the diameter of the exchange-coin. The pawl 58 and recess 45 normally prevent the plate 43 and box 27 rotating in one direction, and the block 59 and bolt 48 normally prevent the said plate and box rotating in the other directron.
The rotatable receiver 27 and the devices for normally locking it and for unlocking it by the insertion of an exchange-coin do not in themselves form part of the present invention; but in order to make the working of the whole apparatus clear we will now describe the receiver and its controlling devices as illustrated in the accompanying drawings, theexample shown therein being particularly adapted for use with our present improvements.
At the other side of the box 27 is a plate 60, one end of which projects through the front of the casing and is provided with a handle 61. This plate has one slot, 62, which engages the trunnion 28, and another slot, 63, which engages the stud 30 on the box 27. A stud 64 is mounted on the said box 27 and projects radially, so that its path cuts the path of the teeth 16 on the wheel 15.
For the apparatus shown in the drawings the action is as follows: Upon an operatingcoin entering the tube 3 through the slot 4 it first strikes and pushes back the inclined tooth 20 on the arm 18. The arm 17 moves with the arm 18 and lifts the pin 19 clear of the teeth on the wheel 15, thus leaving the said wheel free to revolve forward. Next the coin acts upon the tooth 10 of the pallet 8, moving back the lower end thereof and causing the hook-tooth 9 to enter and obstruct the tube 3. Before leaving the teeth 10 and 20 the coin begins to operate that tooth of the wheel 15 which is at the time projecting into the tube 3. To avoid the use of a larger wheel, the wheel 15 is set toward one side of the tube 3, so that a comparatively small part of the coin operates upon the teeth thereof. The pin 19 being clear of the teeth 16, the wheel is revolved to the extent of one tooth 16 by the falling coin, the pin 23 on the arm 24 tripping over one of the ratchet-teeth on the wheel 21. The bell-crank lever 17 18 is released so soon after the coin begins to rotate the wheel that the pin 19 immediately falls and engages the tooth 16 next to the one that has just passed under it, thus preventing the wheel being rotated more than one tooth by each operating-coin. The revolution of the wheel 15 is thus promptly arrested, and it is prevented from rebounding in the opposite direction by the 'pin 23 engaging the shoulder of the ratchet 4 tooth adjacent thereto. The movement of the wheel 15 is accompanied by that of the drum 32, which presents the figure 1 to the sight-hole 33. On clearing the tooth of the wheel 15 the coin passes down the lower end of the tube 3 and through the inclined part thereof, which delivers the said coin into the box 27, and the next tooth on the wheel 15 is left ready to be operated upon by the next coin falling down the tube 3. It will be observed that the operating-coins pass through the mechanism into the collecting-box, and their number is registered and shown one by one by the figures on the drum 32 without any extraneous assistance. 1V hen the twelfth coin has passed through the tube 3, the pin 23 on the arm 24 lodges in the square-sided notch 22, thus preventing further rotation of the wheels 21 and 15 in either direction. If a thirteenth coin fall, it will move back the inclined tooth 10 on the pallet 8 and rest upon the tooth 16 on the wheel 15, for the timebeing obstructing the tube 3. The moving back of the tooth 10 is accompanied by the moving forward of the hook-tooth 9,-which effectually blocks the tube 3 and prevents further coins falling through the tube until the pin 23 is released from the notch 22. If afourteenth coin enter the slot 4, it will rest on the hook-tooth 9 and project up through the slot and will usually lock the coin-freed machine so long as it remains in this position. No further steps can now be taken until thetwelve operating-coins in the box 27 have been ejected therefrom. The action of the twelfth coin has brought the slot 35 round opposite to the pin 39 on the bellcrank 36 37, which may now be moved about its pivot-38. The handle 54 is raised, and the exchange-coin is thrust into the slot 56, when it encounters and pushes backward and upward the end of the arm 37 and on clearing this entersthe pocket 57 of the bolt 48. Part of the exchange-coin remains outside of the easing 2 until forced in by pressing down thehandle 54 onto the projecting part of the coin and onto the surface of the casing 2. This lifts the arm 53 out of the recess 44 and at the same time forces the bolt 48 back against the action of the spring5O clear of thetop of the block 59, and thus allows the plate 43 and'box 27 to be rotated by drawing forward the handle 61, the notch 63 acting on the pin 30, turning the lineal movement of the plate into a rotary movement of the said box. As the box is turned over, the operating-coins therein fall .out through the opening 29 into the chute 65,
'and so are returned to the user.
As the box 27 is thus rotated the stud 3O thereon engages the arm 31, which, acting through the disk 25 and arm 24, lifts the pin 23 out of the notch 22. Duringthe rotation-of the box the stud 64 thereon engages'one of the teeth 16 of the wheel 15, so as to turn the said wheel, and therefore also the ratchet-wheel 21, a little forward. A pin 66 on the side of the drum 32 comes in contact with the (now raised) pawl 58 and prevents the stud 64 turning the wheel 15 too far forward, so that as the box is rotated back again by pushing in the plate 60 and the stud 30 leaves the arm 31 the pin 23 drops into the ordinary notch forward of the squaresided notch 22 and the pawl 58 falls into the notch 45 clear of the pin 66, leaving the wheel 15 again ready to register the number of the next series of operating-coins falling'into the box 27. If there be thirteenth and fourteenth coins in the position above referred to, the thirteenth will now operate the wheel 15 and fall into the box 27 and by releasing the pallet 8 will allow the fourteenth to do the same. The rotation of the said box is transmitted to the bolt 48, and the exchangecoin falls through a slot 74 into a receptacle 79, only accessible by fair means to an authorized person. It will be observed that the exchange-coin drops through the slot 74 before the operating-coins are ejected from the box 27.
Then it is required to exchange different numbers of operating-coinse. g., two numbers of operating-coins for single coins of equivalent values-substantially the same appartus is employed, provision being made for bringing the indicator to Zero when the maximum number of operating-coins is not exan additional bell-crank, similar to 36 37, is
pivoted opposite thereto and provided with a stud 39, adapted to enter a second slot, 35, in the disk 34, or two disks may be employed each having its own slot. The stud and slot 39 35 and the stud and slot39' 35. are set at different angularpositions, so that they cannot be incorrectly employed. On one of the trunnions 28 is mounted loosely a plate 67, having slots 68 and 69 to clear the stud 30 and spindle 13, respectively. It also has an inclined edge 7 0, adapted to act upon the stud 19 and lift it out of the path of the teeth 16 at the proper time. A spring, such as 71, is employed to move the plate forward when the box 27 is turned over forward by the plate 60. Rotating with the box 27 is a toothed sector 72, adapted to engage during the intermediate part only of its stroke with a second toothed sector 73, rotating with the wheel 15. IVhen six operating-coins have entered the collecting-box 27, the slot has arrived opposite the stud 89, and the bell-crank carrying the said stud is left free to move to allow of the insertion of the smaller exchangecoin in its slot, and the box 27 may be rotated by drawing forward the plate 60. As the box is rotated the plate 67 follows up the stud 30 under the influence of the spring 71, and the incline 7O engaging the stud 19 lifts it out of the path of the teeth 16, leaving the wheel 15 free to rotate forward, and the wheel 15 is rotated forward to the extent of the remaining half revolution by the sector 72 engaging with and rotating the sector 73 through half a turn, when the sectors clear one another. On the wheel 15 thus completing its revolution the stud 23 lodges in the square-sided notch 22, but is released by the stud 30 acting upon the arm 31, as previously described. The forward revolution of the box is accompanied by the discharge of the six operatingcoins down the chute 65, and its backward revolution leaves the apparatus ready to deal with the next series of operatii'ig-coins, the stud 30 carrying the plate 67 back clear of the stud 19 against the action of the spring 71 and the sector 72 passing back without'rotat ing the sector 73.
It will be obvious that apparatus constructed in a substantially similar manner may be employed for exchanging other numbers of operating coins or tokens or for other similar purposes.
