COIN-OPERATED MECHANISM FOR DISPENSING LIQUIDS.

Specification of Letters Patent.

Application filed May 9, 1914. Serial No. 837,570.

To all whom it may concern:

Be it known that I, HENRY J. WYKLE,

citizen of the United States, residing at Metamora, in the county of Woodford and State of Illinois, haveinvented certain new and useful Improvements in Coin-Operated Mechanism for Dispensing Liquids; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which .it appert-ains to make and use the same.

This invention relates to a dispensing apparatus and in particular to an apparatus for dispensing liquids such as oil, gasolene and the like.

The primary object of the invention is vice for liquids normally inoperative, the same being coin-controlled and including means whereby it may be adjusted so as to measure and deliver a liquid, such as gasolene, at any prevailing price per gallon.

Another object is to provide a coin controlled normally inoperable liquid dispensing apparatus in which the introduction of a coin will permit operation thereof and the delivery of an amount of the liquid equal in value to the coin at any prevailing price per gallon.

Another object is to furnish a device of the nature described free of complications and that can be manufactured at a low cost besides being readily, easily and quickly adjusted for any prevailing price of the commodity to be sold and one that will be absolutely accurate in operation.

Besides the above objects the invention includes certain details of construction and arrangement of parts as will appear from the following specification and the accompanying drawing forming a part of this application in which,

Figure 1 is a front elevation of a pump showing a part attached thereto which includes my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a front elevation of a cabinet shown in Figs. 1 and 2, much enlarged, my invention being shown therein.

Fig. 3 is a side elevation of parts shown in Fig. 3.

Fig. 4 is an elevation of parts shown in Fig. 3, certain of said parts being shown in a different position from those in the figure last referred to.

' a coin, the other for slugs.

Fig. 5 is a vertical section of one of the parts shown in Figs. 3 and 4.

A represents a pumping cylinder mounted on a suitable base B and provided With a piston C operated by a piston-rod C and a rack bar D. E is a suction pipe connected w1th a gasolene supply tank, not shown. F is a shaft mounted upon and extending into a cabinet G secured in suitable manner to supports H, said shaft being operated by a crank J and including a pinion K engaging the said rack bar D. L is a pipe connected into the top of the cylinder for the discharge of the liquid. Thus far I have described one of the common types of gasoe lene pumps and will now describe my invention in connection therewith.

Since the purpose of the invention is to control the operation of the piston C which delivers the gasolene to the purchaser through the pipe L and to elect the amount to be delivered at a prevailing price per gallon, means is provided for preventing the rotation of the pinion K which operates the rack bar D and this is done by, some such means as the following which, how- 'ever, may be supplanted by equivalent structures.

Secured on the shaft F is a ratchet wheel M and N'is a pawl pivoted to the back of the cabinet at 0, Fig. 3, for example, its end adjacent the said ratchet wheel M having a tooth P to engage said wheel and normally held in engagement therewith by a Patented Mar. 20, 1917.

suitable spring Q attached to said pawl. The

opposite end of the pawl which, in the present instance is in the form of a bell crank, is represented at S. It has a projection T extending from its front surface in position to lie in the path of a coin indicated in broken lines U in several positions, which is guided to said projection by a coin chute V lying adjacent the pawl. This chute is divided into two portions W and X, as shown in Fig. 3, one for the passage of In the last named figure which shows the edge of the chute the projection T is broken away so .as to show an opening or slot 2 lying behind it from which the-coin emerges to lie upon and against the said projection where it remains until a predetermined time, The passages of the two parts W X of the coin chute are separated from one another by a central partition 3, Fig. 3, and a magnet 4 lies upon the outer surface of the chute portion X above the position of the top of the partition 3,. said chute V opening through the top of the cabinet in a coin slot 5. The passage of the coin chute V is a continuous one into the portion W for the passage of a coin which is deposited in the bottom of the cabinet or in any suitable receptacle (not shown) that may be provided to receive it when released from the projection T above referred to. The introduction of a slug that would be attracted by the magnet 4 is deflected by said magnet into the chute portion X and therefore does not reach the projection T of the pawl N. The said portion X is open at its edge opposite that which lies nearest the projection T. The slug represented at 6 is therefore discharged at a point remote from said pawl.

7 is a circular plate or disk rotatably mounted upon a stud 8 projecting from the rear wall of the cabinet. Aflixed to said plate or disk is a pinion 9. In mesh with the pinion is a gear 10 rotatably mounted upon a stud 11 also projecting from the rear wall of the cabinet, and rotatable with said gear is a ratchet wheel 12, the latter in fact serving to impart rotation to said gear.

13 is a rock arm mounted on the stud-11 and provided with a pawl 14 adapted to en gage the teeth of the said ratchet wheel 12. 15 is a stud projecting from the wall of the cabinet upon which is loosely mounted a pawl 16 and an arm 17 which in the present instance is in the form of a gear-segment 17,

the. latter meshing with a pinion 17 mounted to rotate with the described ratchet wheel M. A spring 16 holds the pawl 16 in engagement with the ratchet wheel 12 and prevents backward movement of the same, the pawl 14 in any and all movements of the arm 13 turning the said ratchet wheel 12 forward. The gear-segment or arm is provided with a radially disposed slot 18 within which a block 19 is slidable, Fig. 5. At opposite sides of the block are plates 20 and 21. 22 is a screw extending through the block 19 and threaded into the plate 21. Said screw is shouldered at 23 upon the plate 20 and carried by the shouldered portion is an eye 24 at one end of a rod 25 the other end of which is provided with a similar eye held upon the arm 13 by a screw 26 or other suitable means, the said rod 25 being free to move relative to the parts to which it is connected.

The screw 22 serves to clamp the plates to the arm 17 but when loosened allows the block .19 tobe shifted to desired positions as will appear later herein.

The plate or disk 7 is provided with a notch 27 in its periphery, see Fig. 4, which receives a dog 28 extending from and fixed relative to the pawl N for preventing rotation of the disk in either direction. Ex-

tending at an angle tangentially from the normally in the position shown in full lines,

is adapted to enter the chute U, see dotted lines 3, its entrance being caused by its be ing diverted by engaging a suitable part 33 of the cabinet. 34 is a pin or other suitable part carried by the stem 31 and 35 is a compression spring interposed between the ear 31 and the sald pin 34 and normally holding the button 30 in its elevated position with the member 32 normally withdrawn from the chute.

The gear-segment or arm 17 is provided with numerals adjacent its slot 18 indicating various prices of gasolene and the plate 20 is provided with a suitable indicator 36 which may be set opposite the figure indi cating the prevailing price of the commodity.

The adjustment of the rod 25 in the slot 18 toward either end of the slot results in a greater or less movement of certain of the parts whereby more or less gasolene will be discharged according to the price obtaining at any given time but this will be better understood in the description of the operation. When the apparatus is idle the normal position ofthe pawl N is as shown in Fig. 1 so that the crank J cannot be operated to discharge gasolene.

A coin introduced into the chute V will drop down and rest upon the projection T of the pawl N, lodging between the .upper portion thereof and the opposite wall of the chute. Upon depressing the button 30 the member 32 which is lying normally outside the chute out of the path of the coin, so as not to stop the progress 'of'the coin, will engage the coin and force it downward into the curved inner face of the said projection T between said projection and the into the cylinder a new charge of gasolene' from the tank (not shown) which supplies it.

The first result in turning the crank to the right or anti-clockwise, as viewed in Fig. 3, is to move the gear-segment or arm 17 on its pivot toward the right due to the rotation of the pinion 17 with which it engages. The movement of the gear-segment or arm also moves the arm 13 through the rod 25, and ratchet wheel 12 is turned due to the pawl 14 in a clockwise direction and the gear 10 which rotates with it transmits an opposite direction of rotation to the plate or disk 7 through the pinion 9 on the latter. Simultaneously with this action the cam portion 29 of the disk or plate 7 is moved beneath the dog 28 lifting'the latter a distance sufficient to swing the lower end of the pawl N outward so as to release the coin held by the projection T. After the cam portion 29 has passed a from beneath the dog that member now drops and rests upon the periphery'of the plate or disk and the crank may be turned backward and forward to raise and lower the piston until such time as the notch 27,"

after a full revolution of the plate or disk, arrives beneath the dog 28 whereupon that member through the spring Q is carried into said notch and prevents further movement of the parts, the pawl N simultaneously dropping behind one of the teeth of the ratchet wheel M. The limits of move. ment of the piston C at the ends of the cylinder A determine the extent of rotation of the crank in either direction.

It is now to be noted that with a given length of the arm 13 and a given distance between the pivot point of the gear-segment or arm and the point at which the indicator 36 is positioned, will result in a given movement of the said arm 13 in a given movement of the gear-segment between its limits of movement and in connection with this it is to be remembered that the pawl 14 of the arm 13 causes a certain extent of movement of the ratchet wheel 12 and a certain extent of rotation to the pinion 9 and the plate or disk 7. y

- Suppose that the prevailing price of gasolene is ten cents per gallon and that one full movement of the piston from bottom to top will deliver one gallon then five strokes of the piston will be required to deliver five gallons for a coin representing fifty cents; At this price the indicator 36 will be placed close the bottom of the slot 18 of the gear-segment and in consequence a small movement will be imparted to that end of the rod- 25 in a full swing of the said gear-segment and but a small movement will be imparted to the arm 13, the ratchet wheel 12 and the plate or disk 7.

At each full movement of the gear-segment tom of the cylinder.

as before explained. Thus with the above conditions the complete revolution will be so slow, due to the short movement of the ratchet wheel 12, as to permit of the several required full movements of the piston to discharge the five gallons needed.

However, if the prevailing price of gasolene is say fifty cents per gallon the indicator will then be set opposite that figure in the upper part of the slot and in that event the arm 13 then being swung to much wider limits" by the gear-segment 17, a full rotation of the plate or disk will result at the end of a single stroke of the piston in discharging one gallon, granted always, of course, that the relation of the driving and driven parts are correctly figured. How" ever, with a known discharge of the gasolene in a certain piston travel the figures on the gear-segment can be properly placed.

The number of feet traveled by the piston in the discharging operation, therefore, bears a certain relation to the extent of rotation of the plate or disk 7 and this relation is determined in the present instance by the difference in the length of the arm 13 between its center of rotation and the point of connection of the rod 25, and the length of the arm constituted by the gear-segment between its pivot and the said rod 25. In extreme cases where a still higher price of fluid prevails theindicator 36-may be arranged to be moved still higher in the slot 18 while its other end may be adjusted to any one of a series of holes 13 in the arm 13. In this 'way a wider range'of movement of the end of the rod 25 at the gear-segment results in a longer movement at the arm 13 and a consequently greater travel of the ratchet wheel 12.

The dog 28 and notch 27 in the plate or disk 7 prevents rotation of the mechanism in either direction. The ratchet wheel M however, permits rotation of the crank but in one direction only or that will permit the return of the piston to its lowermost position if, in the discharge of a certain amount of gasolene, the movement of the piston has been terminated at a. position above the bot- Said ratchet wheel M while permitting the return of the piston to its lowered position will absolutely prevent movement in the opposite direction or the delivery of any gasolene until another coin has been inserted.

disk 7 can be turned on account of the dog 28 but the ratchet wheel M can be turned in the direction named since, as viewed in Fig.

3, in the clockwise movement thereof and of The proper positionof the indicator on the 7 gear segment 17 for the measurement of a given amount of the fluid at a certain price can be very readily determined in graduating the scale of prices for a given machine by adjusting said indicator to a point where a movement of the piston will deliver an amount of the fluid corresponding in value to price to be marked permanently on the gear-segment. By this method all prices whether fractional or otherwise can be accurately determined and thus indicated at the slot for subsequent sales when the machine is set up for use. I

The mechanism for measuring the'proper amount of gasolene at a prevailing price is exceedingly'simple and accurate and by reason of its simplicity and few parts it can be produced at a comparatively low cost. It is not my intention to be confined to the exact arrangement of parts described and shown since changes may be made that will lie within the spirit of the invention and the meaning of'the claims whereby the desired described results may be obtained.

Whenever in the claims reference is made to an arm I refer to the gear segment 17 and when the term rock-arm is employed I mean the part 13 and its pawl 14.

Also, when using the phrase mechanism to be operated or operating mechanism I mean the mechanism outside the cabinet Gr.

Also, in the beginning of some of the claims when using the terms operating member or rotatable part the shaft F and its pinion 17 or equivalent part is referred to which is manually operated to impart movement to the entire mechanism.
