MICHAEL A. BORISLAVSKY, OF NEW YORK, N. Y.

LIQUID-LENDING MACHINE.

Application filed October 22, 1924. Serial No. 745,178.

This invention relates to a liquid-vending machine, having more particular reference to a machine for use in dispensing or vending soft drinks. 1

The invention has for an object to provide a novel and improved machine of this type, arranged for delivering a cup, a concentrated flavoring extract, and filtered water, the. flavoring extract being afterward placed in the cup and the latter filled with the filtered water. i

For further comprehension of the invention, and of the objects and advantages thereof, reference. will be had to the follow ing description and accompanying drawing. and to. the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is aface view of my improved vending machine.

Fig. 2 is a vertical sectional view thereof, taken on the line 2-2 of Fig. 1.

Fig. 3 is a detail horizontal sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 is a face view of the package con taining the concentrated flavoring extract.

Fig. 5 is a face view of the blank from which the envelope of the package is made.

Fig. 6 is a detail View of a plunger and its co-operating parts.

In the drawing the reference numeral 10 indicates the lower part of a cup vending machine of the type adapted to deliver paper cups, the upwardly projecting glass maga- Zine being shown at 11. This casing is formed with the usual slot 12 to receive the coin that releases the delivery mechanism. buitably mounted on a common frame 13 with the cup vending device, and spaced laterally from the same, is a vending ma chine of the usual type arranged to deliver small flat packages, this machine being indicated generally at 14 and being provided with the usual coin-controlled ejecting mechanism.

Located between these two devices is a liquid delivering element that is controlled by the operating element of the cup delivering device. This liquid delivering device comprises a casing 18 having an aperture in the bottom thereof surrounded by a. depending flange 19 this aperture receiving a receptacle or cup 20 that projects below the bottom of the casing, and is provided substantially midway between its. top and bottom with a filtering member 21 that extends in the form of a horizontal partition thereacross. At its upper end this cup is provided with a radially projecting flange 23 that is supported by a number of bow-springs 24 attached to the underside thereof and resting on the bot tom of the casing, thereby yieldingly supporting the cup.

Leading into the casing 18, through the back thereof, is a water supply pipe 25 that has its end downturned toward the cup 20 to deliver water into the latter. This pipe is controlled by a valve 26 of the ordinary rotary plug type, whose plug 27 has fixed to one end thereof an elliptical arm 28 having pivoted on its free end a latch 29 that acts to hold the valve in open position. This latch engages a pin 30 projecting from an abutment arm 31 that is pivoted at its upper end as at 32 in the casing and hangs downward therein. The latch 29 is urged outward to en age the pin by means of a spring 33 attac ied at one end theretoand at its other end to the arm 28, while a tail-piece 29 on the latch engages stud 34 fixed to the said arm to limit outward movement of the latch. Attached at one end to the abutment arm 31 and at its opposite end to a rod 35 fixed in the casing walls is a tension spring 36 that normally urges the said arm in a direction to free the pin 30 from the latch 29. I The abutment arm 31 is normally held against movement under the influence of the spring 36 by means of the flange 23 on the cup 20. This flange is engaged by a plunger 40 slidable in a longitudinal boring in the said arm entered thereinto from the lower end thereof, an'expansion spring 41 being located in the said boring above the plunger to urge the latter downward, while downward movement is limited by means of a pin 42 extending transversely through the plunger into short vertical slots 43 in the said arm 31. The lower end of the arm 31 is bevelled off as shown at 45 to form a cam surface on which the flange 23 on the cup 20 bears to swing said arm at certain-times. Swinging movement of the arm 31 is limited by means of the rods 46 and 47 fixed to the walls of the casing and projecting one on each of the arm. The plug 27 of the valve 26 has fixed to its other end an operating arm 50, that is positioned outside the casing 18 and is connected by a rigid bar 51 with the ejecting element of the cup vending element, a knob 52 being fixed to this arm. The arm is retained in normal position by a spring 53.

The package containing the concentrated flavoring is shown in Fig. 4; of the drawing and is in the form of a flat carton formed from a blank 55. In this carton I may place a liquid flavoring in a capsule 56, or a dry flavoring, and a powder 57 to cause effervescence.

In the operation of my improved vending device the user places a coin in the vending element 14: and receives a package containing the flavoring extract, which may be lemon or any other that is desired. A second coin is then placed in the slot 12 of the cup vending element and knob 52 is pulled, both delivering a cup from the magazine 11 and opening the valve 26. When the valve moves to open position the latch 29 rides under the pin 80 and retains the valve open. The Water then flows through the pipe 25 and when the proper quantity has collected in the cup 20 the increased weight of cup causes the springs 24: to be compressed and the cup to drop su'lii ciently to lower the flange below the plung er %O. The arm 31 then swings, under the influence of spring 36, to free the pin 30 from the latch 29, allowing the valve to be closed by the spring 53. This spring also acts to return the cup delivery element to its normal position. A delivery cock 60 in the cup 20 is then opened and the filtered Water allowed to flow into the paper cup that has been received from the magazine 11, the concentrated flavoring extract being placed in this cup. When the cup 20 is lightened by the discharge of the water therefrom the springs 24 urge it upward. As the cup moves upward the flange 23 bears on the bottom of the plunger 40 and moves the latter upward, the flange 23 engaging also the bevelled lower end 45 of the arm 31 and swinging the same to one side until the plunger 40 springs downward again beside the said flange. The flavoring extract may be delivered to the cup 20 through a tube 61.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is as follows 1. In a vending machine, a liquid delivery pipe, a valve controlling said pipe, a lever for operating said valve, a niovabiy mounted cup for receiving the liquid from said pipe, and a latch element controlled by said cup for holding the said valve open.

2. In a vending machine, a liquid deliv ery pipe, a valve controlling said pipe, a lever for operating said valve, a yieldingly supported cup for receiving the liquid from said pipe, a latch element on said valve for holding the same open, and an abutment arm engaged by said latch element, said abutment arm being retained in operative position by the said cup when the latter is empty.

3. In a vending machine, a liquid delivery pipe, a valve controlling said pipe, a lever for operating said valve, a yieldingly supported cup for receiving the liquid from said pipe, a latch element on said valve for holding the same open, and an abutment arm engaged by said latch element. said abutment arm being retained in operative position by the said cup when the latter is empty, said abutment arm having a plunger slidable in the free end thereof engaged on its side by the said cup, the lower end of said abutment arm being bevelled to form a cam surface on which said cup rides to swing the said abutment arm laterally when the cup moves upward after discharge of the liquid therefrom.

In testimony whereof I have atiixed my signature.
