LIQUID-MEASURING rinur.
I Specification of Letters Patent.
Patented Jan. 13, 1920.
Applcation filed August 9, 1917. Serial No. 185,279.
To all whom it mag concern:
Be it known that I, CHARLES F. .PREssLER, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented new and useful Improvements in Liquid-Measuring Pumps, of which the following is a specification.
The invention relates to improvements in liquid-measuring pumps.
The object of the invention is to provide a continuous flow pump, such as the pump described in my 'prior Letters Patent No.
913,848 dated March 2, 1909, with an elecconstructed according to my invention, the
' plunger, the plunger lock and lock releasing case being in section and fractional and the pump .bemg fractional. I Fig. 2 is a plan view of the main gear. Fig. 3 is a rear elevational view of the main gear. Y
Fig. 4 is a plan view of the motor-driven worm and lever support therefor.
Fig. 5' is a front elevational view of the measuring dial.
Fig. 6 is aside elevational view of the mechamsm.
Fig. 7 is a fractional longitudinal sectional view of the plunger lock, and
Fig. 8 is an end elevational view of the plunger lock.
. Referring to the exemplification of the invention in the drawings the entire mechanism will be inclosed preferably in a case, indicated by'10, vso'that the mechanism may be installed outside as well as inside a building for vending liquid such as gasolene, the door of the case, of course, being locked to prevent unauthorized access to the mechanism'. 11 indicates a double acting cylinder, the piston rod 12- of its piston beingconnected to crank 13 on revoluble shaft 14 borne by frame15. Piston rod 16 connected to crank 17 on shaft 14 is also connected to the piston of an auxiliary. cylinder 18 having connection with cylinder 11'. Cylinders- 11 and 18 are described in my prior Patent No. 913,848. Gear-wheel 19 is secured to shaft 14 between cranks 13and 17. "Ifpreferred the piston rods may be connected to the gear. An annular slot 20 is provided in the inner face of gear 19 near its periphery and pins 21 are passed at selected points through the gear and slot and project beyond the inner face of the gear.
A ratchet 22 secured to the lower end of shaft 23 is adapted to-be abutted and rotated by the pins. Gear 24 secured to the upper end of shaft 23 meshes with gear 25 secured to shaft 26, whichshaft drives the totaling register 27 which indicates the total quantity of liquid delivered by the pump during any selected period of time. Worm 28 is secured to shaft 23 and drives gear 29 secured to hub 30 of ratchet 31 (Fig. 6), which hub is revolubly mounted on spindle 32 projecting laterally from bracket 33. A hub 31 on the forward face of ratchet 31 has a split sleeve 31? projecting forwardly from it upon which sleeve is a tapering washer 35. Nut 35 on the end' of spindle 32 'when tightened drives the Washer on the split sleeve and "clamps it to spindle 32. Ratchet 31 is thereby secu'redto the spindle. Index or hand 34-"- is'loosely mounted on hub 31 and has free movement thereon. A latch bolt 36 is slidablysupported by two apertured lugs 36 on the rear face of the index, spring 36 tending to force-the upper end of the bolt'between two teeth of ratchet 31 and lock the index to the'ratchet.' Button 37 is threaded to stud 36 secured to bolt 36 which extends through a slot in index 34 and serves as means for withdrawing the bolt from engagement with the ratchet whenit is desired to manually shift the index upon hub 31 as hereafter 'des'cribedmf For continuous pumping bolt 36 is withdrawn from ratchet 31 and button 37 -.is tightened. against the face of index 34 to hold the bolt. A dial 38 is suitably supported on casing 10, as by I graduations represent gallons, half gallons,-
quarts and pints, the inner set being numbered clockwise and the outer set contra- OlOOkWlSB. The 1nnerset is used to measure 'the quantity of liquid required to fill a conworm gear 39 adapted to mesh with gear 19 and secured to shaft 40, revolubly mounted at one end in a suitable bearing 41 secured to lever 42 and at its otherend in bracket 43 secured to or integral with lever 42. Gear 44 is secured to shaft and is in mesh with gear 45 secured to shaft 46 borne by bracket 43. Gear 47 secured to shaft 46 is in mesh with gear 48 secured to shaft 49 of electric motor 50. The motor is mounted on lever 42 and at suitable points on the lever adjacent the motor are two brackets 51 which are pivoted at 52 to case 10. The pivotal points of the lever are so located that when the lever is rocked toward gear 19 worm 39 will be moved in proper manner to cause its teeth to engage the teeth of gear 19 without injury to the teeth of either; that is, the worm is moved radially to the gear.
A slotted lug 53 depends from lever 42 and pin 53' carried by the frame or casing 10 projects into the slotted lug for support-- ing the lever when the device is inoperative. Link 54 is connected at one end to the free end of lever 42 and at its other end it is connected to crank 55 secured to a suitably supported shaft 56. Link 57 is connected to shaft 56 and to a clamp 57, in which clamp plunger 58 is reciprocably mounted. Spring 58 on. the plunger tends to maintain it in itsouter position. The inner end of plunger58 is reciprocably supported in opening 59 in block 60 and adjacent its end is a peripheral notch 61. Block 60 is fixed immediately in front of the 0 graduations on dial 38 and a stop 62 is provided on the adjacent face of the block by boss 62 which is integral with the block and projects rearwardly from the rear face thereof. A locking plate 63 is pivoted at 64 to this face of the block and covers a portion of open-- ing 59. It also extends above stop 62, a spring plunger 65 carried by stop 62 tendmg to separate the plate and stop and maintain theplate in its normal position. When plunger 58 is forced inwardly toward the dial its notched end forces the depending portion of the locking plate away from stop 62 and compresses spring plunger 65. As soon as notch 61 registers'with the edge of plate 63, spring plunger 65 forces the plate into the notch and thereby the plunger is locked in its inner position. When the plunger is pushed inwardly lever 42, by
means of the connecting links and crank,'is
elevated on its pivots and worm 39 is con A nected to gear 19.
A plate 66 is pivoted at 67 to plate 63 and carries a suitable handle 68 by which it may be rocked on its pivot to theleft (Fig. 8) to a horizontal position. The upperer-d of plate 66 overlaps plate 63 so that it has no movement to the right (Fig. 8) independently of plate 63. A ball and spring 66 is provided in plate 66 which bears against plate 63 and produces sufiicient friction between the two plates to maintain plate 66 in upright position. 1 The lower end of index 34 is adapted to abut the upper portion of plate 66 as it approaches the 0 graduation on the dial and to .rock the plate together with plate 63 to the right (Fig. 8) to release plunger 58, whereupon spring 58 on the plunger restores the plunger to its normal outer position and worm 39 is disconnected from gear 19. The releasing devices for the plunger are effective when a certain quantity of liquid isto be pumped.
In order that the electric motor shall operate only when the delivery of liquid is desired I provide a knife switch 70, the circuit 74 with binding post 75 of the motor and leaf 72 is connected to a switch 76 within the casing, the switch 76 being also connected to one side of the main su ply circuit. The other binding; post 7 motor is connected by wire 78 to the main supply circuit.
v In operation if the owner desires to fill a tank of unknown capacity he places the index on 0 and turns latch plate 66 to the horizontal position by swinging it to the left (Fig. 8), to remove it from the path of index 34. Switch 76 is closed and plunger 58 is'pushed inwardly until plate 63 snaps into notch 61 to lock the plunger. The movement of the plunger is transmitted to lever 42 to cause the electrical circuit to the motor to be closed at switch 70 bycontact member 73 on lever 42 and to engage worm 39 and gear 19. As the gear is rotated its pins drive ratchet22 and shaft 23 intermittently for rotating ratchet 31 and the index clockwise. When the tank is full switch 76 is thrown to cut-out the motor and the quantity of liquid pumped into it is read on the inner series of graduations on tion and the plunger is pushed in as before.
The index travels over the dial toward the 0 graduation and as 'it approaches 0 it meets;
of the i the dial. Plunger 58 is released by elevat- 'ing plate 66 to its normal vertical position plate 66 and rocks it and plate 63 to automatically release the plunger. Whereupon the Worm 39 disengages from gear 19 and the motor circuit is broken at switch 0,
and-the pump almost instantly stops. e quantity of liquid pumped will be found to correspond to that. indicated upon the dial in the one case and to that for which the index was set in the second case.
It is obvious that the several gear ratios and sizes and arrangementof the parts may be varied to suit conditions, the embodiment of the invention'above described being only an illustration of a convenientarrangement. I What I claim is: 1. The combination with a pump mechanism, of a pivotally supported driving mechanism adapted to be connected to the pump mechanism, means to cause the two mechanisms to engage, means to' lock said mecha nisms in engagement, means havingan operative connection to oneof said mechanisms for automatically releasing the engagement of said mechanisms, and means to control the operation of the driving mechanism.
2. The combination with a pump mechanism, of a pivotally supported driving mechanism adapted to be connected to the pump mechanism, means to cause the two mechanisms'to engage, means to lock said mechamsms in engagement, means having an operative connection to one of said mechanisms for automatically releasing the engagement of said mechanisms upon the delivery bythe pump mechanism of a predetermined quantity of liquid, and means to control the operation of the driving mechanism.
3. The combination with a pump mecha nism, of a pivotally supported electrically driven member-adapted to-be connected to the pump mechanism for operating the same, means to cause the driven member to engage the pump mechanism, means to lock the said engagement of said driven member and pump mechanism, means to'release the said engagement of the driven member and the pump mechanign when thepump mechanism has delivered a selected quantity of liquid, and means to control the operation of the driven member.
