COIN-CONTROLLED VENDING-MACHINE.

Patented Jan. 23, 1906.

Application filed October 6, 1904. Serial No- 227,488-

To all whom it may concern:

Be it known that we, FRED E. HALL, of Brookline, Norfolk county, and ALEXANDER MAoLEoD, of Brighton, Suffolk county, State of Massachusetts, have invented certain new and useful Improvements in Coin-Controlled Vending-Machines and we do hereby declare the following to be a full, clear, and exact description of the invention, such as vn'll enable others skilled in the-art to which it appertains to make and use the same.

The primary object of this invention is to provide an improved coin-controlled vending-machine which shall be simple in construction and highly efficient in operation and one which can be operated only by legitimate coins.

Further objects are to effectively discard spurious disks or slugs and discharge them, so that they may not clog the operating parts, and to generally simplify the construction and promote the efficiency of machines of this character.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims. A

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view, the inclosing casing of the machine being omitted and parts of the merchandise-holding tubes broken away. Fig. 2 is a front elevation with parts in section and parts broken away. Fig. 3 is a bottom plan View. Fig. 4 is a top plan view with parts omitted. Fig. 5 is a view in perspective of the cord-cutting rod.

Fig. 6 shows the parts for preventing the ejecting mechanism from being again operated until returned to its normal position. Fig. 7 shows in section one of the coin-supporting levers and its adjuncts. Fig. 8 is a view of the actuating frame with parts broken away.

Referring to the drawings, 1 designates a plate or casting forming the bed of the operative parts of the machine. It may be of such width as to accommodate any desired number of mechanisms and is ordinarily mounted 'within an inclosing casing (not shown) of any preferred form. From this plate extends an upright or vertical plate 2, in which are formed a series of coin-inlet openings 3, of which only one is shown, such openings corresponding in number and position to the number of separate ejecting mechanisms used. In the present description only one such mechanism will be referred to. To the rear of plate 2 is secured a plate 4, the space between the two plates being sufficient to permit of the passage of a coin. Such coin after passing the inlet-opening 3 is guided in a tortuous course by ribs 5 and 6, the space between the ribs forming a passage-way 7. It is thus difficult, if not impossible, to force coins or slugs through the passageway at a greater speed than that of ordinary gravity. The plate 4 is formed with a cut-out 8 extending over a portion of the passage-way to form an opening through which bits of paper, wires, or other material will pass if inserted in the inlet-opening.

To a lug 9, extending from plate 4, a magnet 10 is secured by a screw and clamp 11. This magnet is placed at an angle of about forty-five degrees to the vertical, paralleling the lower side of one branch of the passageway 7, and its poles are extended through a slot formed in plate 4, so as to intersect the passage-way on a line continuous with rib 6. In this way coins or slugs descending the passage-way will roll for a part of their course across the poles of the magnet. A coin or non-magnetic disk will drop from the magnet to the operating mechanism immediately beneath, while a disk of iron or steel will be whirled to one side between plates 2 and 4, as indicated by the curved line 12, Fig. 2, and will be discharged through an opening 13 without reaching the coin-controlled mechanism, such opening being formed in plate 1 to one side of the operating parts.

14 and 15 designate two levers mounted upon bearing-pins 16, depending from plate 1, such levers being held in their normal retracted positions by coil-springs 17, their movements being limited by stop pins 18. Normally the levers are in an approximately straight line with each other, their inner opposed ends being directly beneath the lower end of the coin passage-way 7. These ends of the levers are notched out at 19, the space between the two notches being slightly less than the diameter of aproper coin. If adisk of less diameter or thickness should fall between the notched ends of the levers, it will not lodge on the latter, but will drop out in front of the machine and be returned to the patron. It has been found in practice that with the notches beveled at about the angle indicated in Fig. 7, which is approximately a right angle, with one wall slightly longer than the other, very fine distinctions may be made in the diameter or thickness of coins and slugs; but inorder to provide for the utmost accuracy and nicety in guarding against coins of improper dimensions we provide means for regulating or adjusting the depth or angularity of the notch of one of the levers, so as thereby to increase or diminish the space between the two levers. For this purpose a pin 21 is passed transversely through lever 15, the opening therefor intersecting the vertex of the notch. This. pin (see Fig. 7) is itself provided with a notch 22, designed to register with the walls of the notch of the lever. its axis the distance between the centers of the notches of the two levers may be increased or decreased with the greatest nicety. When in position, this pin is held tight by a jam-nut 23. In their normal positions the notched levers 14 15 occupy a plane slightly in advance of a dividing-wall 24, in line with which is the normally forward wall 25 of the cash-drawer 20. The result is that imperfect coins or disks of inferior size which do not lodge between the notched levers will fall forward of the wall 24 and drop out in front of the machine, thus being returned to the depositor. On the other hand, coins which remain between the levers, being discharged therefrom after the latter have been moved rearward, fall into the money-drawer rearward of wall 24. In plate 1 is formed a rectangular opening 26, beneath the front end of which the levers 14 and 15 are located.

27 designates an actuating-frame formed with a central opening 28 and grooved sides 29, which are designed to slide along the parallel edges of the rectangular opening 26, the central opening 28 normally'being above the notched levers 14 and 15. This frame has at its frontafiat wall in the form of an upper ear 30, having an opening 31, and a lower ear 32, having an opening 33. To this lower ear a retaining-spring 34 is secured, while to the upper ear is attached the operating-plunger 35, which passes outwardly through an opening in plate 2 to the front of the machine. By pushing inwardly on this plunger the frame 27 may be forced rearwardly, its movement being limited by contact with a stop 36. (See Fig. 3.) The width of the lower ear 32 be ing less than the distance between the two notched levers, such ear is free to pass between the latter without interfering therewith. The opening 31 of ear 30 is coincident with a bore 37 of plunger 35, and in line therewith isja horizontally-disposedrod 38, mount- By turning this pin on Y sieve"? ed upon a casting 39, secured to plate 1. The forward end of this rod is sharply notched, as shown at 40, Fig. 5. When the plunger is pushed rearward, it telescopes rod 38, so that if an attempt should be made to repeat the operation of the machine by a coin or disk attached to a string such string will be caught by the notched end of the rod and being forced into the opening 31 and possibly also into the plunger will be cut off. The string will naturally follow the coin to which it is attached and will thus occupy a position about in the vertical center of the plunger. In order to define this position more accurately, a notched cross-piece 41 is secured to plate 4 near the lower edge thereof and eX- tends across the passage-way 7 with its central notchin line with the notched end of the string-cutting rod 38.

The ejecting part of the mechanism embraces a block or casting 42, provided with side grooves for hugging the parallel edges of the rectangular opening 26. Upon this casting is mounted a spring-held ejector 43 for engaging the lowermost article of merchandise within tube 44, such tube being provided with a guide-plate 45, which serves to guide the ejector in its proper path. Through a depending portion of block 42 is passed a rod 46, which is firmly held by a set-screw 47. A coil-spring 48, encircling this rod, holds the block in its normal position against the stop 36. This rod 46 is in. direct line with the opening 33 of ear 32 and about midway between the notched levers. When a coin has been properly positioned between the latter and the actuating-frame 27 is pushed rearwardly by pressure on the plunger, causing the notched levers to turn on their fulcra, the coin will before being freed of engagement with the levers contact with rod 46 and will push it and the ejector 43 rearwardly. The

coin is now held firmly between the end of rod 46 and the lower ear 32. Upon the return of the parts to their normal positions the coin cannot reenter the notches of the levers: but as soon as it is free from engagement with rod 46 and being no longer supported between it and car 32 will fall into the money-drawer. If the attempt should be made to operate the machine by means of a washer, the rod 46 will pass through the hole in the latter when the plunger is pushed rearwardly, and hence the ejector will not be operated. When the plunger is actuated, the washer will be released from engagement with the notched levers, the same as a coin, and when the plunger is released the washer will be drawn back along the rod by means of the forward wall of frame 27 until it shall have reached the end of the rod (which passes through such wall) and will then fall into the cash-drawer.

In order that the same coin may not be used for a second operation, we provide improved means for making it impossible to again push the plunger rearward after completing on'e operation until the engaging coin has been discharged. For this purpose a horizontally-disposed rack 51 is mounted on plate 1 adjacent to one side of opening 26. A spring-held two-way pawl 52 is carried on a pivot mounted on an upright 58 of frame 27, such pawl being designed to engage the rack and prevent the actuating member from being returned to its normal position until its full stroke has been completed, at which time the pawl will be relieved from engagement with the rack. When the return stroke begins, a reverse engagement exists between the pawl and the rack, so that the actuating member cannot be pushed rearwardly again until the return stroke has been completed. Before the completion of such stroke the coinwill fall through opening 26, as heretofore described. It is necessary that the actuating member shall be freely movable back and forth without operating the machine in order that it may always return to its normal position if the plunger is pushed without the previous deposit of a coin. For this purpose a movable shield 54 is jplaced over rack 51. It is ivoted at its rearward end by a shouldered screw 55, fitted in one side of block 42, and is held over the rack by a sprin 56. Thus the shield is designed to trave back and forth with the ejector member. This shield on its under side is beveled at 57 to form a cam, which upon being brought into contact with a stationary pin 58 will be forced laterally as against the tension of its spring 56. When the shield is in its normal position covering the rack, the pawl cannot en age with the latter, but will slide back and forth along the upper surface of the shield. WVhen, however, a proper coin has been inserted in the notched levers and the ejector-block is pushed rearwardly with the actuating member, the shield will be forced to one side upon its beveled wall 57 engaging pin 58, and the rack will thus be exposed, so that the pawl will come in engagement therewith in the manner described. The lateral movement of the shield is limited by a stop-pin 59.

The plunger 35 is not directly below the center of passage-way 7, but is a little to the side opposite the side discharge-opening 13. If, therefore, the plunger should be pushed in first and the coin inserted afterward, such coin upon contacting with the plunger will roll off to one side and pass through opening 13 to the front of the machine, the plunger preventing the coin from reaching the notched levers.

From what has been said it will be seen that a machine constructed in the manner herein described is very efiicient and reliable under the presence of a proper coin, but that its operation by the fraudulent methods usually practiced is difficult, if not impossible.
