Fig. S iS a diagrammatic view showing a modified form. Fig. 9 is a similar view of a further modification.

Referring now to the drawings in detail, l, l designate two instruments, although any number may be employed, controlled from what may be termed a switch board or central station 2. Each instrument `coinprises a substantially rectangularreceptacle 3 provided with a vertically disposed transverse partition 4 spaced apart from one end wall thereof and dividing the receptacle into small `and large chambers and 6 respectively. Seated upon the upper edges of the side and end walls'of the receptacle 3 and closing the-upper end of such receptacle is a base plate 7 constructed of any suitable material and formed in the front wall of the chamber 6 is a door opening adapted to be closed by means of a door S capable of swinging movement to open position and equipped with a lock 9 whereby the door may be locked against opening movement.

The front wall of the small chamber 5 is formed with a finger opening 10 while disposed at the back of the small chamber and forming the rear wall thereof and spaced apart from the adjacent portion of the back wall of the casing is a plate 11 having the lower portion thereof curved toward the front wall of the small chamber and concaved longitudinally in order that any coins lying thereon may be readily removed by inserting the finger through the opening 10 and drawing thesame over the concaved face`of the plate 11; fThe top wall of the small chamber 5 is formed with a substantially rectangular opening 12 and upstand ing from the marginal edges of the wall Vof the opening 12 and suitably secured thereto is a substantially rectangular shell 13 constructed of any suitable material and projecting up into the shell 13 is the upper end of the plate 11. rhe space between the confronting walls of the plate 11 and back portion of the casing form a slot 11 having a downwardly inclined bottom wall 15 and opening into the large chamber by way Of an opening 16. Connected with the upper edge of the plate 11 and lying in a horizontal plane above the upper open end of the small chamber 5 is a platform 17, while connected with the front wall of the shell 13 and extending rearwardly beneath the platform 17 is a lguard 18 spaced apart a suitable distance from the under surface of the platform and designed to prevent the passing of the fingers through the top of the small chamber and into Contact with the platform. Secured to the opposite ends of the casing and upstandiiig therefrom are supporting standards 19, while uprising from the rear wall of the casing and having the opposite longitudinal edges thereof secured to the adjacent edges kof the supporting standards is a back wall 2Ol Arranged between the standards 19 adjacent to the upper ends thereof and lying parallel with the back wall 20 is a coin receiver 21 equipped at its opposite end edges adjacent to the top edge thereof with outwardly projecting trunnions 22 journaled in horizontally alining' bearings 23 carried by the standards. ln

the present instance, this coin receiver comprises a rectangular block 21 composed of suitable insulating material such, for instance, as glass, and formed with vertical slots 25, 26 and 27 designed to receive coins of various denominations, the slot receiving twenty-five cent pieces, the slot 26, tencent pieces, and the slot 27, five-cent pieces. Although we have shown the block 21 as being formed with three slots, it will be understood that the number of slots may be varied and as many as desired, employed. Secured to the back wall 10 and projecting forwardly therefrom below the coin receiver 21 and disposed at the opposite extremities of the latter are horizontally alining bearings 28 in which is journaled a shaft 29 and depending from the shaft 29 is, what may be termed, a multiple coin chute 30 composed of a block- 31 of insulating material, such as glass, formed with a vertical longitudinal chamber 32 having the upper end thereof 'opening onto the upper edge of the block and disposed below the slots 25, 26 and 27 in the coin receiver and alining therewith. Also formed in the block 31 is a Vertical chamber 33 disposed behind the chamber and parallel therewith and adapted to register with the lower ends of the slots 25, 26

and 27 in the coin receiver when the latter 32 inclines downwardly toward the shell 13 and the side wall of such chamber adjacent to the slot communicates with the shell by way of a slot 3l whereby coins. other than the proper one, and checks deposited within the slots in the coin receiver and dropping into the vertical chamber iii registration with the coin receiver will be restored to the depositor by way of the slot 3l, the shell and the small chamber The bottom wall of the chamber 32 inclines downwardly toward the platform 17 and the side wall of the chamber adjacent to the platform is formed with a slot communicating with a hood 36 carried by the said side wall of the chamber and surrounding the slot therein, the lower end of the hood being; disposed immediately above the platform 17 and opening thereonto by way of a slot 37.

ln the present instance, vertically disposed electromagnets 3S, 33 are suitably fastened to the inner face of one of the standards 19 between the latter and the adjacent end of the coin receiver, and fastened to the adjacent end of the shaft 29 is a horizontal armature 39 disposed within the influence of the poles of the magnets 38, 33. rlhe magnet 33 is disposed at one side of the axis of the shaft 29 and controls one end of the armature, while the magnet 33 is disposed at the opposite side of the axis and controls the remaining end of the armature. Thus, when the magnet -38 is energized the armature is actuated to swing the multiple coin chute in one direction, while when the magnet 38 is energized and the magnet 38 deenergized thejarmature is actuated to swing the mutliple coin chute in the opposite direction. In this embodiment of our invention, the upper edges of the opposite walls of the vertical chamber 32 in the block 31 below each slot 25, 26 and 27 in the coin receiver are formed with coacting sockets and disposed within each set of'sockets are the opposite legs of inverted U-sliaped pins 40' having the interconnecting portion thereof spanning the upper end of the chamber and spaced apart in parallelism. The interconnecting portions of the pins 40 below each slot are spaced apart a distance slightly less than the diameter of the coin that the pai'- ticular slot is adapted to receive and the upper portions-of such pins incline rearwardly as at 41 so that a coin resting thereon may be moved off of the same with ease and facility and dropped into the chamber 33. Connected to or formed integral with the pins 40 of each pair are contacts or binding posts 42. i i

Secured to the back i yail 20 and insulated therefrom are holding pins 43 corresponding in number with the slots in the coin respective slots. The forward ends ofthe holding pins 3 project into apertures 44.-

formed in the adjacent iace ol' the block oi the coin receiver and when the coin receiver is swung out of normal position, the torward ends of the pins obstruct the slots and enter apertures l5 formed in the front face oli' the block and alining with the apertures 44. ln this instance, an electromagnet 4G is secured. to the base plate 7 and disposed within the influence ot' the pole of the magnet #lil is a horizontal 'armature l-T capable or' swinging movement and connected with the lower end ot' a vertical lever 48. such lever having the upper end thereof inturned and contacting with the coin receiver 2l.

S designates a switch board or central station from which the instruments l, l are controlled and located upon the switch board is signaling mec ianism which, in the preferred embodiment of our invention, embodies incandescent signal lamps 49, 50 and 5l corresponding with the slots 25, QG and 27 respectively.. Pivotcd upon the switch board is a switch blade movable over a number of contacts 58 corresponding in number with the stations controlled from the switch board, while. mounted upon the switch board are push button switches 5l, 55 and 5G controlling the magnets 38, 38 and i6 respectively of each instrument.

One side of the lamps 19, 50 and 5l is connected by way of a conductor 57 with one side of a suitable source of electrical energy, while leading from the remaining terminals of the lamps are conductors 58, 59 and GO extending through the stations controlled from the switch board. The switch blade 52 is connected with the opposite side of the source of energy and leading from each station is a common return conductor G1 connected with one of the contacts 53 in the path ofthe blade 52. @ne side of the push buttons 54, 55 and 56 is connected with the side of the source of energy to which the conductor 57 is connected by way of a conductor 62, while from the remaining sides of the push button lead conductors 63, 64 and 65 extending through the various stations controlled from the switch board. Tapped onto the conductors 58, 59 and 60 respectively at each station are conductors 66, G7 and 68, each terminally connected with one contact of the pairs of pins below the slots 25, QG and 27 respectively in the coin receiver, while connected with the free contacts of the pairs of pins is a common wire 69 tapped onto theA common return conductor 61 ofthe particular instrument. Conductors 70, 7l and 72 are tapped onto the conductors 63,. 64: and 65 respectively of each' instrument and are terminally connected with one terminal of the magnets 38, 38 and 4 6 respectively, while the remaining terminals of such magnets are tapped onto lthe common return conductor 6l of the particular instrument.

messie ln practice, assuming our apparatus to be installed in a hotel, tor example, one instrument is disposed in cach room, or suite ot rooms, while the switch board is located at the clerkls desk. Should the occupant of one of the rooms desire to purchase food or drink or the like from the hostelry, such occupant calls the clerks desk on the telephone and advises the clerk of his wants. The clerk, previous to sending the order to the room ot' the occupant requests the latter to deposit the money covering the cost of the order in the instrument and, assuming the order to cost fifty cents the occupant deposits two twenty-tive cent pieces in the slot :25 in the coin receiver-.f` lhe lirst coin rests upon and bridges the pins l() below the Aslot whereby the coin is held within the slot, while the second coin rests upon the edge of the tirst coin. As thc particular set of pins i() are bridged the circuit is closed through the signal lamp lf), the switch blade having been previously swung into engagement with the contact 53 connected with the common return wire ot' the particular instrument, current flowing through the conductor 57, lamp lf), portion of the common conductor 5S, the conductor UG or the particular instrument, across the bridged pins l() and back to the other side of the source of energy by way ot' the com- 'mon wire (39, common conductor Gl, contact 53 and blade rlhe signal lamp l) being energized, the clerk is advised that the proper coin has been deposited in the instrunient and the clerk, desiring to remove the coin, depresses the push button switch '5G whereby the magnet i6 is energized, current liowing from one side of the source ot' energy, through the conductor (32, push button switch 5G, the particular portion of the conductor 65, the conductor 7 2 of the active instrument, the winding ot' the magnet lo and then back to the other side of the source oi energy by way of the conductor G1, contact 53 and blade 52. As the magnet i6 is energized, the armature 47 is swung about its fulcrnm and the lever 48 actuated to swing the coin receiver about its axis thereby disengaging the bottom coin from the pins 40 and enabling such coin to drop into the vertical chamber 33 and so gravitate to the hood 36 and onto the platform 17. In this swinging movement of the coin receiver, the stop pin or holding pin 43 behind the slot 25 is disposedv across the latterand bears the weight, with the remote wall of the slot, of the top coin in the slot, thereby preventing the second coin from falling out of the receiver. The button 56 is now released and the magnet 46 denergized whereby the lever 48 and coin receiver are restored to normal position and as the coin receiver moves to normal position the coin therein isv relieved of the influence. of

the particular holding pin and so gravitates onto the pins l0 thereby again bridging the pins and `closing the circuit through the signal lamp 9 whereby the clerk is advised that the second quarter is in the machine. To collect the first quarter, the clerk depresses the button 51 thereby closing the circuit through the magnet 3S and energizing the latter, current tlowing from oneside of the source ot' energy, through the conductor 62, button 5l, the particular portion ot' the common conductor G3, the conductor 70 ot' the particular instrument, the winding of the magnet 3S, and then back to the other side of the source of energy by way of the common return conductor 61 of the instrument, the contact 53 and blade 52. Upon the energization of the magnet 38, the armature 39 is actuated to swing the multiple coin chute 30 whereby the hood 36 carries the coin olf of the platform so that such coin will. drop through the slot -H and opening' 1G into the coin chamber 6. To disengage the remaining twenty-live cent piece from the pins 40, the button 56 is again depressed whereby the magnet 46 is energized to again swing the coin receiver and drop the coin into the vertical chamber 33 in the multiple chute, the coin gravitating to the platform 17. To collect the coin the push button 54E-is again operated whereby the magnet 38 is energized and the multiple coin chute swung as previously described so that the coin drops into the chamber 5.

Y Should the clerk have discovered that the order of the occupant of the particular room or suite of rooms was twenty-five cents instead of fifty, after the money had been deposited withinthe machine, the rst twentyive cent piece would have been thrown into the coin chamber as previously described, while the second coin would have been returnedto the depositor and to effect such returnof the coin the button 55 would have been depressed so that the magnet 38 would be energized to swing the coin chute 30 in the reverse direction thereby carrying the coin olf of the platform and dropping such coin through the shell 13 and into the small chamber 5 whence it could be removed by Way of the finger opening 10.

Should a coin of smaller diameter than the proper coin be deposited in any one of the slots, ysuch improper coin will fall bee tween the pins 40 into the vertical chamber 32 and through the slot 34 into the small chamber 5.

When a live-cent piece is deposited in the slot 27 in the coin receiver the signal lamp 51 is energized,.while when ten-cent piece is dropped inthe slot 26 in the coin receiver p the signal lamp 50 is energized.

Diierent means may-'be employed to restore the multiple coin chute to normal position and to maintain the same in. such .money in the instrument.

position. In this form of our invention, we have shown a coiled contractile spring 57, such spring having one end secured to the bottom wall of the coin chute 30 and the opposite extremity fastened to the base plate 7.

In the modified form of the invention illustrated in F ig. 8, we employ a galvanometer 73 in lieu of the signal lamps and calibrate the face or dial of the galvanometer to read in numbers corresponding with the various amounts of money which the instruments are capable ot containing, and connect in series with the contact pins l-LO resistance grids or sections 7 1 adjusted to correspond with the galvanometer. Thus, should one or more coins be deposited in an instrument and the latter connected in circuit with the galvanometer the indicator finger or hand of the latter will move over the dial thereof to indicate the amount of For instance, should five, ten and twenty-five cent pieces be deposited in the respective slots all the resistance 7i will be cut out and, assuming the switch blade to be on the contact connected with the common return wire of the particular instrument, the indicator finger of the galvanometer moves over thedial to the number l0.

In the construction illustrated infFig. 9, the signal mechanism comprises solenoids 75, 76 and 77 corresponding with the slots 25, 26 and 27 respectively.' These solenoids are disposed within the switch board and mounted within each solenoidis an armature 7S having one end thereof equipped with a stop collar 79. Encircling the armature 78 between the stop collar and the adjacent end of the solenoid is azcoiled eXpansion spring 80, while fast to the opposite end of the armature is a sign plate 81 indicative of the denomination of the coin to be received by the particular slot. Formed in the cover of the switch board are sight openings 82 spaced apart and corresponding with the solenoids. When one of. the solenoids is energized the armature thereof is actuated against the action of the spring 80 and the sign plate connected thereto thrown into the sight opening. Y

From the foregoing description taken in connection with the accompanying drawings, the construction and mode of operation of improved coin collecting apparatus will be readily apparent. It will be seen that we have provided a coin collecting apparatus or system whereby the coin or coins may be collected and retained within the machine or returned to the depositor if desired, while false coins or checks will be returned to the depositor without affecting the signals.

The front, top-and sides of each instrument are closed by means of a suitable coverv mesme S3 and closing the mechanism above the receptacle 3 and cooperating with the back wall Q0.

ll'hile we have herein shown and described certain preferred` forms of our invention by way ot' illustration, we wish it to be understood that we do not limit or confine ourselves to the precise details of construction herein described and 'delineated, as modification and variation may be made within the scope of the claims without departing from the spirit of the invention. Furthermore, we wish it to be understood that any number of instruments may be controlled from the switch board and the capacity of the instruments varied in accordance with the circumstances or exigencies of any particular case.
