19 Claims.

This invention relates to coin collector apparatus particularly such apparatus for use at a telephone pay station.

As applied to a telephone pay station the pres- 5 ant invention is particularly adapted for that type of coin collector wherein the calling party tentatively deposits a coin or coins and the money under the control of the central office is later collected or refunded depending upon whether or not the desired connection is obtained. In such apparatus as shown, for example, in the O. F. Forsberg Patent 1,043,219 of November 5, 1912, it heretofore has been customary to have the coins temporarily deposited upon a pivoted coin trap located in a coin hopper and normally supported by a deflector vane adapted to be actuated by a polarized electromagnet to allow the trap to drop and discharge the money either into a collect chute or refund chute de- 20 pending upon the direction of movement of the supporting vane. The coin trap of the Forsberg patent is provided with a counterweight to restore the trap to normal position after the coins have been discharged.

An object of this invention is to provide improved apparatus for temporarily retaining deposited coins within a coin channel and for later disposing of the coins in a desired manner.

As applied to the type of coin collector shown in the Forsberg patent the coin trap of this invention comprises a plate adapted to be moved about one bearing for coin collection and adapted to be moved about a second bearing for coin refunding, the trap actuating mechanism 35 comprising means for subjecting the plate to a lateral movement followed by .a rotative movement about either of said bearings. Thus the coin trap preferably comprises a plate normally lying above two supporting pins spaced apart a distance slightly less than the length of the plate. The tilting of the plate may be controlled by a toggle joint comprising a short arm fastened to the lower side of the plate and a long arm rotatable about a fixed pivot, the two arms being hinged together with the hinge having an extension adapted to be actuated by the coin relay. In the normal coin supporting position of the trap the two specified arms are in alignment but when the relay is energized the resulting arcuate movement of the hinge causes the plate to first move laterally to clear one of its supports and then tilt downwardly to discharge the coins from the plate into a collect chute or refund chute depending upon the direction the 'relay armature is actuated.

Referring to the drawings:

Fig. 8 is a perspective view partly in section of the hopper of this invention; .and Figs. 9 and 10 are rear and side views respectively of an alternative form of the invention.

In general, the portion of a telephone coin collector shown in Fig. 1 is similar to that of the Forsberg patent in that the upper housing I0 encloses a multiple coin chute ll for receiving deposited coins and the coins discharged from chute ll drop into the upper portion I2 of a coin hopper and actuate a pivoted coin trigger I3 to close electrical contacts (not shown) whereby the polarized electromagnet I4 is placed under the control of the central office to enable the electromagnet to be energized later to cause its armature l5 due to armature extension l6 to discharge the deposited coins either in a collect chute or refund chute, depending upon the polarity of the applied current.

After actuating coin trigger l3 a deposited coin drops upon a fiat plate I! normally supported within the hopper above two parallel sta- 3 tionary pins or rollers 18 and I9 spaced apart a distance slightly less thanthe length of plate l'l. Each of the pins l8 and Hlpasses through apertures in the front wall 20 and rear wall 2| of the hopper and may, if desired, be rotatably supported thereby,

. Midway its length plate H has two downwardly projecting arms 24, ZE'adjacent the front and rear walls of the hopper, these two arms projecting in a direction perpendicular to plate H and being apertured at their'lowcr ends to receive a pin 26. Pin 26 projects through an arcuate slot 21 in front wall 28 to be embraced by the forked end 28 of armature extension 16. Located below pin 26 and just above the convergence of the bottom walls of collect chute 35 and refund chute 37 is astationary pin 29 suitably supported between the front and rear walls of the coin hopper. This pin 29 acts as the pivoting axis for an inverted U-shaped member 30 D whose arms 3| and 32 at their lower ends are apertured to receive pin 29 and whose arms at their upper ends are apertured to receive pin 26. Pins 26 and 29 are parallel to each other and when the plate I1 is in its normal coin supporting position the two pins 26 and 29 lie in a common vertical plane bisecting plate that is, arms 25 and 3| are in alignment with each other and arms 24 and 32 are in alignment with each other when plate I! is in its normal coin supporting position.

As shown particularly in Figs. 5 and 8 the coin hopper is of special construction in that the upper tubular portion I2 extends downwardly a short distance below the top wall 49 of the enlarged lower portion 4| of the hopper, and the diametrically opposite edges 42 and 43 of the tubular portion immediately above the ends 34 and 36 of plate I! are preferably beveled for a purpose to be described later. The distance between rod I8 and edge 42 and the distance between rod 9 and edge 43 are preferably just suflicient to allow freedom of movement of plate H from its normal position to either of its coin discharging positions. Rod l8 and beveled edge 42 by restricting the movement of plate in a vertical plane jointly define an axis or bearing about which the plate pivots for coin collection. Similarly, rod l9 and beveled edge 43 by restricting the movement of plate I! in a vertical plane jointly define an axis or bearing about which the plate pivots for coin refunding. It will be obvious that beveled edges 42 and 43 may, if desired, be replaced by rollers similar to rollers |8 and I9.

In order to prevent the possibility of a thin coin becoming wedged between the lower edge of the tubular portion of hopper l2 and the upper surface of plate H, the hopper tubular portion may be provided with a plurality of spaced downwardly projecting pins or extensions 44 to 49 which project centrally into slots 50 to 55, respectively, of plate I1, pins 44 to 49 preferably being of such length that they do not project below the lower surface of plate H in its normal position. The tubular hopper portion also has a downwardly projecting pin 56 lying outside the path of plate arm 25 and another downwardly projecting pin 51 lying outside the path of plate arm 24. These pins 44 to 49 and 56, 51 serve to prevent any coin from being wedged between plate I1 and the bottom edge of the hopper while freely permitting the coin discharging movement of plate I! and the subsequent movement to normal. In order to show the preferred ratio be tween the diameter of hopper l2 and the diameter of a dime, a dime 58 is shown lying on plate I! in Fig. '7.

The manner in which the coin trap I1 is operated by the electromagnet I4 is best described in connection with the schematic showing of Fig. 2 where the full line H represents the plate in normal coin supporting position supported above spaced rollers IB and I9 with the adjacent ends of arms 25, 3| pivoted about movable pin 26 and with the other end of arm 3| pivoted about the stationary pin 29. If we assume that pin 26 in Fig. 2 is moved counter-clockwise along an arcuate path with pin 29 as an axis, plate will first be subjected to a substantially lateral movement until its edge 34 is free of roller |9 whereupon with further counter-clockwise movement of pin 26 the plate will begin to rotate clockwise about an axis lying between rod l8 and hopper edge 42 as shown in intermediate position until with pin 25 in its fully operated position the plate assumes position H" where it is tilted downwardly an extent sufficient to ensure that all coins on plate ll will be discharged into collect chute 35 leading to the cash compartment of the collector. When pin 26 is moved from its fully operated position 25 to its normal position the plate H will be rotated counterclockwise about an axis lying between rod l8 and hopper edge 42 and as the result of which the right edge 34 of the plate will be lifted upwardly until it lies above roller l9 so that for the last portion of the restoring movement of pin 26 plate will be moved substantially laterally to the right to enable the right edge 34 to again be supported above roller l9. It will be obvious that for a movement of pin 26 from its normal position to its fully operated position in a clockwise direction the left edge 36 of plate II will first be freed of roller l8, and the plate ll then rotated counter-clockwise about an axis lying between rod l9 and hopper edge 43 to enable any coins on plate I! to be discharged into a refund chute 37 leading to a coin pocket accessible to the user of the instrument.

In actual operation under coin load, plate may contact with rod l8 for its initial rotative movement for coin collection and then contact with edge 42 for the remainder of its coin discharging movement. In being restored from its coin collect position to normal, plate II will generally remain in contact with edge 42 until the plate has substantially reached its horizontal position. Similarly, for coin refunding, plate H in its initial rotative movement may contact with rod I9 and then contact with edge 43 for the remainder of its coin refunding movement while in its return to normal it will generally remain in contact with edge 43.

It will, of course, be understood that the abovedescribed operation of the coin trap is secured by the energization of polarized electromagnet l4 which for one polarity of applied current will cause its armature extension E5 to move pin 26 counterclockwise to tilt plate i1 and discharge coins into the collect chute 35 and which for applied current of the opposite polarity will cause its armature extension Hi to move pin 26 clockwise to tilt plate IT in the opposite direction and discharge coins into refund chute 31.

After the cessation of the energizing current for electromagnet l4, armature extension I6 is restored to its normal position by means of one of the restoring springs 39 in the same manner as in the Forsberg patent. The restoration of armature extension It ,to normal ensures that coin trap I! is positively restored to its normal coin supporting position. It is also to be assumed that when electromagnet 4 is deenergized the previously mentioned electrical contacts will be reopened and coin trigger l3 restored to normal in the manner described in the Forsberg patent.

In Figs. 3 and 4 of the drawings, the coin trap l1 and associated parts are in their normal positions with plate I! supported above rollers Ill and I9 and with arms 25, 3| and arms 24, 32 vertically aligned with pin 26 lying at the midpoint of slot 21.

In Figs. 5 and 6 the plate H and associated parts are shown in their coin discharging position for coin collection with the upper end of plate against hopper edge 42. The position of these parts for coin refunding position would be the reverse of that shown in Fig. 5 with pin 26 in its maximum clockwise position and with plate I! tilted downwardly from hopper edge 43 to direct the coins towards refund chute 31. It will be noted particularly from Fig. 5 that when plate H has been tilted to direct the coins into one of the branch chutes 35, 31, the plate is in a position to block the entrance to the other branch chute.

In a preferred form of the invention with pin 26 in its normal position and arms 25, 3| in alignment, there is a small amount of play allowed plate ll between the bottom edge of the hopper and the rods l8 and It. For example, plate ll may have a thickness of of an inch and the distance between the upper side of rod I8 or I!) and the adjacent bottom ho per edge 42 or 43 may be of an inch. The combined length of arms 25, 3| or arms '24, 32 is preferably such that in normal position the under surface of plate ll need not be in contact with either rod E5 or l9. As to the length of plate ll compared to the distance between rods 58 and it it was found satisfactory in one embodiment of the invention to have plate H in its normal position extend about of an inch beyond the center of each pin l8 or H! where each pin had a diameter of A; of an inch.

Figs. 9 and 10 show a modified form of the invention where the lower tubular portion 65 of the coin hopper has no projections corresponding to pins 44-69 of Fig. '7 and the coin supporting plate El has noslots corresponding to the slots shown in plate ll, particularly in Figs. '7 and 8. Movable pin 62 corresponds to pin 26 of the earlier figures except that pin 52 does not project outside the coin hopper. The lower ends of the plate tabs 63 and 64 are apertured to receive pin 52 and the inverted U-shaped member 65 has the upper ends of its arms 66, El apertured to receive pin 62 while the lower ends of arms 66, 61 are pivoted about the stationary pin 68. Member 55 differs from member 355 of the earlier figures in that its arm 55 extends below'pin 58, then outwardly through an arcuate slot 69 in a side wall of the hopper, and then upwardly to a point above pin 58 Where its end carries a pin it engaging the fork extension ll of the coin relay armature. It Will be apparent that the energization of the coin relay to move extension ll will serve to tilt plate 6! for coin collection or coin refunding in substantially the same manner as described for the earlier figures.

The form of the invention shown in Figs. 9 and 10 has certain advantages over the form of Figs. 1 to 8. A deposited coin is less likely to become wedged in slot 59 of Fig. 9 than in slot 2i of Fig. 3; and the total amount of travel required for armature extension H is less than the amount of travel required for armature extension it since pin it described an are on a shorter radius than the are described by pin 26.

It will be apparent that if desired the non-slotted plate 55 may be actuated by the linkage of Figs. 3 to 5 and that the slotted plate 'll of Figs. 3 to 5 may be actuated by the linkage of Figs. 9 and 10.
