LIQUID-VENDING DEVICE.

Specification of Letters Patent.

Patented Nov. 30,' 1909.

Application filed May 18, 1907. Serial No. 374,397.

To all 'whom-it may concern:

Be it known that I, IIENRY G. CORDLEY, a citizen of the United States, residing at Glen Ridge, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Liquid-Vending Devices, of which the following is a description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to liquid vending de` vices of the type wherein a coin forms a connecting member between two reciprocating members one of which is designed to be operated by the purchaser and the other of which serves as a means for operating a valve whereby the flow of the liquidV is con trolled; andthe object of my invention is to produce a simplified and more efficient device of the type above defined.

Vith this object in view my invention con-v sists in the improved liquid vending device illustrated in the accompanying drawings, described in the following specification, and distinct-ly claimed in the clauses of the conln the accompanying drawing Figure 1 is a longitudinal sectional view of my device, taken upon a vertical plane through theaXis thereof; Fig. '2 is a similar sectional view taken upon a horizontal plane and showing the left hand portion of the device shown in Fig. 1; Fig. 3 is an elevation of the inner end of one of the reciprocating members of my device; Fig. 4 is a view of my device attached to a type' of water cooler with which it is designed to be used. Fig. 5 is a longitudinal sectional view of a portion of my device and illustrating a slightly modified form of valve mechanism; Fig. 6 is a view similar to Fig. 3 andshowing-an additional feature used in certain instances; and Fig. 7

is a view showing means whereby I adapt my devicefor use with a supply of liquid under pressure. L

The body portion or casing of my device in the embodiment thereof illustrated in the drawings comprises two main sections 1 and 2 andan intermediate connecting secL tion 3. The section 1 is shown as secured to 'the section 3 by a threaded connection at 4,

at 7 through which a portion of one of the reciprocating members of my device passes.

A connection is indicated at 8 through zontally extending ledge 12; and it is obvious that a coin inserted through a slot 13 in the upper side of the section 1 will ,fall upon and be arrested by the ledge 12, while the ledges 10 and 11 will forni a support for the vertical face of the coin.

14, 14 are slots formed in the tubular member 9, and 15 is a pin passing through holes in the section 1 and through the said 16 is a disk resting against the pin 15, and 17 isa spring interposed between the disk 16 and the push piece 10 and acting to force the member 9 toward the left and maintain it in The section 3 is provided with a stuiiing box the position shown in Fig. 1. The member Y 9 is also provided with slots 18, 1S located in a plane at right angles to that of the slots 14, 14,' for the purpose of' allowing the inner end of said member to move past springs located within the section 1 as hereinafter disclosed.

20 is a second reciprocating l,member extending through the stuiing boX` 7 and provided with an abutment here shown as a p rojecting disk portion 21, and an extending stem portion 22, upon which stem portion is located a valve 23. This valve is free to move upon the stem 22, and a spring 24 between the valve 23 and the' disk 21 forc the valve against a. shoulder 25 on the stem 22. The stem 22 is prolonged as at 42, which projection is adapted to engage the valve 30 hereinafter mentioned to force it from its seat.

26 is a spider .attached to and moving v with and acting as a guide for the valve 23,

and 27 is a seating surface against which the valve 23 seats.

The section 2 is provided with an internal abutment or shoulder 28, and 29 is a sprin located between said shoulder 'and the dis 21 and acting to force the disk and reciprocating member 20 toward the left and maintain it in the position shown in Fig. 1 of the drawing.

A3() is a second valve carried by a stem 31 and guided by spiders 32, 32, and seating against a seating surface 33. A spring 34 keeps this valve closed against its seat.

'35 is a measuring vessel preferably of glass, and secured to the section 2 by suitable coupling means as shown; and 36 is a conduit through which the liquid purchased is delivered to the purchaser. The measuring vessel 35 is in open communication with the atmosphere b means of an opening 43 in the upper en thereof, to permit the escape of air as liquid enters the measuring vessel.

38 is a passage leading from the interior of the section 1, and through which coins Y fall to a suitable coin receptacle not shown.

39, 39 are yieldin members, here disclosed as springs, t e section 1 and are here shown as securedV at one end thereto. The

free ends of said members are provided with. projections at 40, herein shown as formed by` 4bending the ends of the s rings so as to form inwardly facing hoog-like members, the purpose of which is to catch the coin and insure its discharge from the ledge 12 of the reciprocating member 9. A

In Fig. 4 I have illustrated my device as used by me with one of Vmy improved water coolers. In said figure, 45 is anlouter receptacle for containin ice, which receptacle is provided with a'suitable cover 49. 44 is an inner receptacle for containing water supplied from an inverted water bottle 47.

The casing of my coin controlled device is represented as a whole by the reference character 48, and the measuring vessel thereofV and supply conduit leading thereto by 35. and 8 as in the other figures. The line A B, indicates the level of water in the inner receptacle, and in the measuring vessel after cating member 9 to the right and the coin is# carried past the ends of the springs 39, 39,

which are free to swing apart to permit the coin to pass by them, and is brought into engagement with the inner ends of the second reciprocating member 20. From this point the members 9 and 2Q move together and the valve 23 is thus forced to its seat, thereby cutting off communication between the conduits 36 and 37. The reciprocating niembers 9 and 20 continue their movement, the

stem 22 moving through the valve 23, and. v

the projecting end 42 of the stem 22 is lbrought into engagement with the valve 30 and force it open, when-the movement of the several parts toward the right ceases. The valve 23 being now closed upon its seat and the valve 30 open, liquid from the receptacle 44 is free to flow through the connection 8 and conduit 38 into the measuring glass 35 until the level therein corresponds to the level of the liquid in the receptacle 44. The operator now permits the reciprocating member 9vto move to the left to its original position, during which movement the valve 30 is first colsed, thereby cutting oi' communfication between the-,coupling 8 and conduit 36; and the valve 23 then opened,

thereby establishing communication between the conduits 36 and 37 and permitting the liquid in the measuring vessel -35 to flow therefrom to a suitable receptacle placed so as to receive it. During the first part of the movement to the left of the parts above enumerated the coin moves with the member 9; but the disk 21 of the second reciprocating member 20 soon comes into engagement with the connecting section 3, and stops,v thereby relieving the coin from pressure to which it has been subjected by the spring V29; and as the member 9 continues its movethe inner end of the said member will pass I by the inner end of the second reciprocating member 20 without operating it, if the member 9 is pressed to the right without a coin havino' been first dropped into the Vslot 13. The s ots 18 in the member 9 permit the inner end thereof to pass by the free ends of,- the springs 39, 39, as said member is pushed inward. Y

In Fig. 5 I have illustrated my device with a slightly modified form ofthe second reciprocating member and valves operated thereby. In this ligure, 50 is the slot for receiving the coin, and 51 the lopening through which the coin leaves the device. 52,53, 54, Y

provided with an enlarged head 57, between l which and the partition 53 is located a spring 58 corresponding in function with the spring 29 in Fig. 1. 59 is a stop for limiting the returnmovement of the member 56.A The be unnecessary.

member 56 isiprolonged and has, a valve 60 free to move thereon, and a spring 61 holds the valve against the stop 62 until the valve reaches its seat 65, and yieldsV during the continued movement of the member 56. 63 is a second valve provided with a recess 64 into which the end of the member 56 enters, and which recess forms a' guide for the end of said member. The valves 60 and 63 in this form of my device seat against soft rubber seats 65 and 66 located in rabbets in the section 55. 67 is the supply conduit, 68 the conduit leading to the measuring vessel and (S9-the discharge, all as' in the device illustrated in Fig. `1. 70 and 71are spiders for supporting and .guiding thei'stem 72 of the valve 63. The operation of this formA of my'device is identical with the operation above disclosed of the form shown in Fig. 1, and detailed statement thereofV is believed to My device as thus far disclosed is designed to receiveand be operated by a penny. I, however,contemplate adopting it for dispensing liquidsto be sold at live cents or a nickel per glassor other quantity, in which case l cut away the central portion of the supporting ledge 12- thereby forming two projecting coin supports 73, 73, separated by an open space 74, as shown-in Fig. 6. This space'is slightly wider than the diameter of Aa tightjoint between the parts, .82 are o i a penny. W'ith this arrangement, it will be seen that while a penny or coin of less diameter and thickness' than a five cent piece or nickel may be dropped through the slot 13,

.the device cannot lie-operated by such a coin,.

for as soon as the reciprocating member 9 is moved toward the right the coinwill pass through the space 74 and fall into the coin receptacle without operating the valve mechanism.- y

While I have disclosed my device as used in connection with a water cooler in which a constant level is maintainedwhi,ch7level is below the upper'end of the measuringvessel, I also use m device for dispensing. liquids the level .o which is above the upper end of the measuring vessel, or which are under pressure. In suchlcases means mustl befprovided for preventing the liquid from overflowing through the a1rvent or opellin- 43 in the upper end of; the measuring ve'sse In said Vfigure 75 is a rnipp'le hav1n` g a valve seatf .76531; its lower endh against which seats va valvei' havinga downwardly extending Astein 78; "9 is a cage 'acting'.as a guide ..for

the valve 77, and serving also 'asa means' for securing the various parts in position the upper wall of the measurin and 86, 81 are packing gaskets orsecuring- Y iii.: f

inthe cage 79, and 83 is a liollo'w'fall adapted to float upon the surface of the' .a normally open valve carried by said recipuid in the measuring vessel 35, and to engage the stem 78 of the valve 77 and'close said valve as the float approaches theuppcr end of the measuring vessel. With this arrangement, it is obvious that air may escape freely `from the measuring vessel as liquid Hows .thereinto, vand that the escape of liquid is prevented by the valve 77 which will be closed by the iioat83 as the level of the ,liquid lin the measuring vessel approaches the upper end thereof.
