UNITED STATES PATENT'OFFICE SIDNEY L. LONG, OF MINNEAPOLIS, MINNESOTA LIQUID-VENDING MACHINE Application filed May 29, 1989. Serial No. 386,934.
This invention aims to provide novel means ceptacle 11, there is a longitudinal guide 26 for dispensing material such as liquids, in on which an desired number of weights 27 predetermined quantities, and althoughaprecan be slida ly mounted. The lever is fcrred form has been shown, let it be underada ted to be held in the inclined position 6 stood that a mechanic working Within the of Figure 1 b a latch 29 fulcrumed at on scope of what is claimed may make changes a post 28 in t e housing 1. A pin 31 on the without departing from the spirit of the inpost 28 engages in an arcuate slot 32 in the vention. I latch 29 and limits the movement of the latch.
In the accompanying drawings which il- AS Shown in Figs. 3 and 4, the latch or look- 10 lustrate one form in whlch my invention may g devlce 29 is provided with a lower notch b b di d; 60 and an upper notch 61, the purpose of Figure 1 is a vertical section wherein the h h W111 presentl appear. receptacle is lowered; Figure 2 is a similar h upper end 0 a link 33 is pivoted to the view with the'receptacle raised and in filling latch and the lower end of the link is 15 position; Fi 3 4 d 5 are ti ivoted to a side bracket on a coin lever 34 taken, respectively, on the lines 3-3, 4 -4,- ulc rumed at 35 on the post 28, the com lever d 5-5 f Fi 2, having a weight 36 at one end, and a com Th frame f th hin i l d a b receptacle 37 at the other, the numeral 38 like housing 1 divided by a partition 2 into markmg a chute carried y the housmg 20 di i compartment 3 d a i 1 and dlschargmg into the coin receptacle 3?.
50 of the lever 15 which is remote from the reunder circumstances which will be made 46 to assume a vertical depen manifest hereinafter. The inner end of the link 48 is pivoted to the upper arm of a bell crank lever 53 fulcrumed on a standard 54 in the housing 1, the lower arm of the bell crank lever having a side pin that extends under the radius arm 16.
In practical operation, suppose that the parts are arranged as delineated in Figure 1 of the drawings. The 0 erator places a coin in the chute 38, the com rolling along the chute and acquiring lodgment at length'in' the coin rece tacle 37 on the lever 34. The lever 34 is ti ted, by the wei ht of the coin. into the dash line osition 0 Figure 1, and the coin rolls out o the receptacle 37, into the coin compartment 4. When the lever 34 is tilted as aforesaid, b the weight of the coin, the link 33 swings t e latch 29 clear of the lever 15, the movement of the latch 29 and conse uently the movement of the lever 34 towar the dash line osition of Figure 1, being regulated by the en h of the slot 32 in the latch 29, wherewith t e pin 31 cooperates, in a manner which will be understood readily when Figure 4 of the drawings is noted.
When the lever 15 has been set free, by the operation of the latch 29, as aforesaid, the right hand end of the lever 15, and the receptacle 11 move upwardly, responsive to the action of the weights 27. At this time, i
the weights 27 are at the inner end of the guide 26 and, as a result the receptacle 11 is not slammed up violently against the valve stem 8.
As the left hand end of the lever 15 moves downwardly past the horizontal, the weights 27 slide to theleft hand end of the guide .26, thereby making the weights the more effective as a means for pressing the rece tacle 11 against the valve stem 8. When t e right hand end of the radius arm 16 moves upwardly from the osition of Figure 1 toward the position of Figure 2, the radius arm 16 no longer bears on the pin 55 of the bell crank lever 53, and the barrier 46 swings by gravity into a vertical position, the operating member 49 sliding longitudinally through the pivot element 22 on the extension 21 of the lever 15. The reason for permitting the barrier ing position for a time, is in order ,that the rece tacle 11 may be raised from the position of i are 1- to the position of Figure 2, without hitting the barrier; but by t e ,time that the recep- ,tacle 11 is raised to the position of Figure 2,
the finger 52 on the operatin member 49 has engaged the pivot element 52, and the barrier 46 is swung beneath the elevated receptacle 11.
When the valve stem 8 is raised, and the valve 9 unseated, by the lifting of ,the receptacle 11, as indicated in Figure 5, the upper end of the stem 8 comes into contact with the stop 10. Liquid flows from the tank 5 through ,the spout 6 into the cup 12 within the receptacle 11 and the weight of liquid dispensed is governed by the mass of the weights 27 on the guide 26, since the receptacle 11 will start to move downwardly as soon as theweightofliquid in the cup 12 overcomes ,the action of the weights 27 plus the friction of moving parts of the mechanism. The receptacle 11 ultimately arrives in the position shown inFigure 1, and the operator can remove the cup 12 through the opening 14. At a pretermined time in the tilting of the lever 15 to the position of Figure 1, the wei hts 27 slide again to the right hand end of t e guide 26. As soon as the left hand end of the lever 15 has been raised far enough, ,the latch 29 will swing by gravity beneath it, and hold the parts in the position of Figure 1 until another coin is deposited in the chute 38. When the arts are in the position of Figure 1 the ra ius arm 16 engages the pin 55 and tilts the lever 53, the link 48 swinging the barrier 46 above the receptacle 11, thereby to prevent access to the stem 8, and to avoid the obtaining of material without depositing a coin.
When the lever 15 swings from the position of Figure 1 to the position of Figure 2, the keeper in 44 on the lever 15 enga es automatical y with the seat 45 in the atch 39, and when the lever 15 swings from the position of Figure 2 to the position of Figure 1, the keeper pin 44 is disengaged from the seat 45 of the latch 39. The latch 39 is employed for two purposes, to wit, to overcome the downward ,thrust of the valve stem 8, when the receptacle '11 is ralsed, as in Fig ure 5, and to overcome the pull of the barrier 46. If there were no valve stem 48, or no barrier 46, latch 39 and the keeper 44 could be dispensed with, since the weights 27 and the liquid in the receptacle 11 serve to tilt the lever 15 back and forth and operate the machine. 7
It will be also noted that the action of closing the barrier serves to check the speed of the receptacle at both the upper and lower position. As the receptacle moves upwardly, the element 22 engages the finger 52 and retards the'upward movement of the receptacle. Also, as the receptacle moves downwardly, the arm 16 and t e pin 55 operate in a like manner to bring the receptacle gently to rest at the bottom.
The functions of the dog and rack previously mentioned are to make a full movement of the mechanism imperative, the main object being to cause the cup to be completely lowered and locked in position before the dog is freed from the rack. Otherwise, a cup could be stopped before it reached the bottom sition and before the lever was locked, the liquid taken out, a new cup put in, and sent up to be filled, without the use of a coin.
It is to be noted that the action of closing the'barrier 46 serves to check the speed of the receptacle 11 at both the upper and lower positions thereof. As this receptacle moves upwardly, thefinger 52 engages the element 22 and retards the upward movement of the receptacle. Also as the receptacle moves downwardly, the arm 16 by engaging with the pin 55 operates in a like manner to bring the receptacle ently to rest at the bottom. It is to be noted also that the sliding weight 27 and also the engagement of the dog 23 with the rack 25 serves to vary the speed of the receptacle 11. The function of the dog 23 and the rack 25 is to make a full movement of the mechanism imperative, the main object being to cause the cup to be lowered with the lever ready to be locked in position before the dog is freed from the rack. Otherwise, a cup could be stopped before it reached the bottom position and before the lever was locked, the liquid taken out, a new cup put in, and returned to upward filling position without the deposit of a coin. Two notches and 61 on the latch 29 are used in looking the device as will appear from Figs. 3 and 4. The lower notch engages the lever before the dog leaves the rack while the second notch makes engagement with the lever after the dog 23 leaves the rack 25. If it were not for the lower notch 60, a person might stop the downward movement of the cup as soon as the dog leaves the rack and before the upper notch engages the lever so that the machine might be defrauded in the manner previousl stated by a person emptying the cup and re lling it without depositing a coin. While I have disclosed my dispensing machine as being set in operation by a coin, I do not herein claim any novelty in the coin-control mechanism per se, and it is obvious that the machine may be set in operation by other forms of applied force beside the weight of a coin.
