Figure 16 is a sectional elevation taken substantially in the plane as indicated by the line lidi6 of Figure 15.
Referring first of all more particularly to Figure 1, the liquid dispensing apparatus consists essentially of the base 30 adapted to support the casing 32, the framing 34 secured to the base and within the casing being provided with the platforms 86 and 38, the platform 36 being adapted to support a pump 40 and the motor 42 which is operatively connected to said pump. The suction side of the pump is connected through the pipe 04 to the source of liquid supply 46, and upon operation is adapted to draw the liquid from the source of supply 46 and supply it to the inlet side of the meter 48 through the pipe 50. An expansion chamber 52 may be provided associated with the pump for taking care of any expansion in the liquid dispensing apparatus. The outlet side of the meter 48 is connected through the pipe 54 to the sight gauge 56 to which the hose 58 is connected, the end of the hose being provided with the nozzle valve 60 having the operating handle 62 and the guard 04 associated therewith.
The meter 48 is provided with the rotating shaft 66 controlled by suitable pistons provided in the meter, the shaft being connected to registering and computing mechanism 68 as illustrated in Patent No. 1,888,533. The registering mechanism is adapted to be reset by means of the shaft 'l0 controlled by the crank'l'2. The operation of the motor 42 is controlled by a suitable electric switch '|4 interposed in the current conduit 16, the switch being controlled by the link 18 connected to the switch operating arm 80, said arm being pivoted as at 82 to the interlocking mechanism housing 84. The switch operating arm 80. is associated with the nozzle support 86 secured to the housing 84, the housing 84 being adapted to be secured to the framing 34 in the casing 32. v
Referring now more particularly to the form of interlocking mechanism illustrated in Figures 2 to 7 inclusive, the switch operating arm 80 is loosely connected to the lever, 88 pivoted to the housing bracket 90 as at 92, the opposite end of the lever 88 being loosely connected to the interlocking rod 84 through the block 96. The rod 94 is mounted for reciprocating movement in the track 98 provided in the housing 84, and the opposite end of therod y.is adapted, inthe zero position of the registering mechanism 68,
to be received in a suitable aperture or cutout` portion |00 provided in .themember |02 of the' the outer end of said shaft being provided -with' the reset crank 12.
The reset shaft is provided with the cam I8 adapted to engage the plunger |20 mounted for reciprocation in the housing 84 and urged upwardly toward the cam 'by means of the springv |22, the plunger being loosely connected to the leg |24 of the bell crank |26, said bell crank being pivotally mounted as at |28 to the housing 84, the depending leg |30 of the bell crank being loosely connected to the latch |32 slidably mounted in the channel or track |34. The inner end of the latch $32 is urged downwardly by means of the spring |36 provided in the housing 84 the inner end of the latch being notched as Y at i 38 to provide a latch member |00, the notched portion being adapted to embrace the upwardly extending latch arm |42 provided on the switch arm 80. The latch arm |02 is provided with oppositely facing latch ledges |04 and |46 adapted to have latching cooperation with the latch member |00 of the latch |32.
In operation of this form of the'device, assuming the registering mechanism to be in zero position and the switch 14 to be in 0E position as shown in Figures 2 and 3, when it is desired to operate the liquid dispensing apparatus, the switch arm is raised to the position as indicated in Figure 5 to close the switch 74. Movement of the switch arm 80 in a counterclockwise direction to raise said switch arm causes rotation of the lever 88 in a counter-clockwise direction as viewed in Figure 4 whereby the interlocking rod 84 is raised to cause the end of said rod to enter the aperture |00 of the member |02, thus preventing any tampering with the registering mechanism 68. The cam ||8 will be out of engagement with the plunger |20 wl? ereby the latch |32 will have been moved toward the right as viewed in Figure 4, the latch portion |40 riding up on the bevel of the latch ledge |44 whereby the arm 80 can be moved to full upward position to close the switch 14.
After dispensing the requisite amount as indicated by the registering mechanism 68, when it is desired to shut oi the flow of liquid, the switch arm is depressed to the position as illustrated in Figures 6 and 7. Depressing the switch arm causes the lever 88 to move in a clockwise direction to lower the interlocking rod 94 out of engagement in the aperture |00. Lowering the rod 94 causes the latch member |40 to ride oif the ledge |44 and engage behind said ledge |44 whereby the switch arm cannot be re-raised without resetting the registering mechanism 68. This is done by rotating the crank 12. Rotation of said crank causes rotation of the reset shaft |04.
Rotation of said shaft causes the cam ||8 to depress the plunger |20 to cause the bell crank |26 to be rotated in a clockwise direction to move the latch member |32 toward the left as viewed in Figure 2. 'I'his will cause the latch member to ride up on the bevel of the latch ledge |46 and remain there by virtue of engagement with has been reset to zero-and the operator has re nl, moved the discharge hose 58 from, the switcl'iffv arm 80lfor serving a customer, but the regis- 'tering mechanism will not 'reach its zero position until the aperture |00 is alignedv with the interlocking rod 94. Therefore the switch arm 80cannotbe raised to operatethe switch until the aperture isin `that position, at which time.
the operation just described takes place, raising of the arm 80 causing the latch member |40to' again ride up'the bevel of latch |44.
Referring now more particularly to the form of interlocking mechanism shown in Figures 8 to 16, inclusive, the interlocking mechanism housing |50 is adapted to be secured to the framing of the liquid dispensing apparatus in the casing as already described with respect to the housing 84, the nozzle support 86 being secured to the bracket |52 of said housing. The switch operating arm |54 is pivoted as at |56 Within thev housing 50 and has an inwardly extending arm |58 loosely connected to the link 18 for operation of the switch'l.
The switch operating arm is provided with the cam |60, said cam being provided with the locking shoulder |62 extending substantially parallel -to the axis of the shaft |64 forming the pivot |16, the other leg |18 of said lever being urged upwardly by means of the spring |80, fastened to the casing, said leg being adapted to have operative engagement with the plunger |82, said plunger slidably extending upwardly through the casing.
'I'he shaft |64 is provided with the crank |84 loosely connected at |86 to the interlocking rod |88 slidably mounted in the housing. The reset shaft |80 for the registering mechanism is suitably journalled as at |82 in the housing and provided with the reset knob |84, said shaft being provided with the cam |86 disposed in alignment with the plunger |82, and the shaft is also provided with the member |88 aligned with the interlocking rod |88 and provided with the apertured or cut out portion 200 for the reception of one end of the interlocking rod |88.
In operation oi' this device, assuming that the registering mechanism is in the zero position and the parts in the positions as illustrated in Figures 8, 9 and l0, with the switch arm lowered, when it is desired to start the motor the switch arm is raised, causing the link 18 to close the switch 14. Raising the switch arm |54 to the position as illustrated in Figure 11 causes the locking shoulder |62 to move in a counter-clockwise direction as viewed in Figures 10 and 13 to move the locking portion |10 out of engagement with the leg |12 of the lever |14, causing the lever |14 to drop down onto the cam |60.
After the liquid has been dispensed and it is desired to render the liquid dispensing apparatus inoperative, the switch arm |54 is lowered to the position as illustrated in Figures 14, 15 and 16.
Lowering the switch arm causes the leg |12 of thelocking lever |14 to drop off the cam |60, it being noted that the cam is of less height than the locking portion |10 so that the long leg |12 of the lever will engage between the cam and the locking portion |10 as shown in Figure 16. It will therefore be impossible to raise the switch arm |54 as the shaft |64` is locked so long as the registering mechanism has notbeen moved to the zero position.
Assuming that the discharge hose is hung up. on the switch-arm |54, the turning of the reset knob |84 to reset the registering mechanism back to zero position causes cam |86 to push down on plunger |82, which contacts the leg |18 of the locking lever |14 and pushes it down far enough to force the other leg |12 of the locking lever up high enough to permit spring 202, which is interposed between the housing and the leg 204 provided on said locking portion, to move the locking portion |10 to a position below the leg |12, but the switch arm |54 cannot be moved to close the switch 14 until full zero position, when the cut out portion 200 of the member |88 will be in alignment with the interlocking rod |88, at which time upward movement of the switch arm causes the interlocking rod to enter -the cut out portion to permit depressing the link 18 to close the switch to operate the dispensing apparatus.
It will thus be appreciated that with the interlocking mechanisms illustrated simple means is provided for preventing further operation of a liquid dispensing apparatus until such time as the registering mechanism has been set to zero position, and in the event that the switch arm has been raised and the motor started whether or not any liquid is dispensed and the switch is again pulled down to inoperative position, it is necessary to again reset the registering mechanism back to the predetermined or zero position before the switch arm may again be raised, and it is to be understood that we. do not wish to be Hunted by the exact embodiments of the device shown, which are merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
