MECHANICAL CUT-OUT FOR FLOAT-METERS.

Application filed December 16, 1919.

To all whom it may concern:

Be it known that l, Linnaeus E. BAKER, 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 Mechanical Cut- Outs for Float-Meters, of whichthe followinpis a specification.

My invention relates to float meters, and particularly to means for disengaging the rack from the gear that meshes therewith to actuate the indicating and registering mechanism.

Under some conditions containers having float meters must be emptied back into the storage tank or other source of supply instead of the liquid bein dispensed to the customers tank or other point of usual delivery; and as the meter is to register and indicate the liquid dispensed not including that returned to storage, cut-out mechanism to prevent the operation of the meter'is necessary in such cases. My invention provides such mechanism. a

My invention is illustrated in the accompanying drawings in which Figure l, is a. sectional elevation of an elevated container for liquid, exposing to view a float meter and its uprightrack in position to operate the meter,

Fig. 2, is the samewith the drain back valve open and the rack withdrawn from meshing contact with the rack gear of the meter; so as to cut-out the meter from operation,

Fig. 3, is a cross section on the line 33 of. Fig. 1, as though the container was there shown in full, and

Fig. is a cross section on the line 4-4 of Fig. 2, as though the container was there shown in full.

Referring now to the drawings; A, is the cylinder of an elevated container usually made of glass or provided with windows, a, is the container bottom and a is the top, these parts being suitably con nected by tie-rots a The container is mounted upon a pedestal P.

B, is the discharge pipe vertically slidable through the stuffin box a C, is the till pipe and D, the overflow pipe fixed in position within the container.

A drain-back orifice E, is provided in the bottom of the container to carry back to Specification 01'. Letters Patent.

the storage tank the contents of the container when so desired, as when locking up the apparatus for the night. A needle valve 4 guided by the bracket 6 is adapted to keep the orifice E, normally closed and to be raised to open position by manipulation of the lever 6 being pivoted thereto by a screw 0, provided to adjust the length of the needle valve element. This screw c is left protruding from the upper end of the needle valve 0, a distance sufficient to allow some upward movement of the lever 6 before lifting the needle valve 6, from its seat in the orifice E, for a purpose hereafter to be described. The lever c is pivoted at 6 to a bracket, a}, on the container top a. The free end 6, of the lever 6 is adapted to contact with and be raised by the top of the discharge pipe B, when raised to drain back position, *Obviously the lever 0 may be operated in any other convenient manner.

A float meter F, with a suitable rack gear f, is adapted to operate the meter 7, only while the float is descending.

The gear f, is normally in mesh with the teeth of the rack F at all times during operation of the apparatus. The guide bars f 7, are fixed to the top a and the bottom a, of the container, and are so spaced. that the rack F, is free to move between them within the limits allowed by ains f i fixed in the bars f f and tree in me parallel diagonal slots 7, f in the rack F A connecting rod f, is pivoted at one of its ends to the back of the rack F and at its other end to the lever e in such a manner that before the needle 6, is lifted to open the orifice E, the rack F will be withdrawn from meshing position with the Dinion f,

so that the float meter descends with the body of liquid when the liquid is being drained back to storage with the meter not re istering.

3 V hen the lever 6 is lowered the needle e, closes the orifice and thereafter the connecting rod 1, slides the rack F into operative position with the pinion f, all by gravity. V

Whatever means will produce disengagement of the rack and its pinion during that movement of the float meter on which nor mally metering occurs, is within the scope of my invention.

I claim as my invention and desire to secure by Letters Patent of the United States:

1" In combination with a float meter having a rack gear, fixed upright guiding means upon which said float meter rises and falls, an upright rack adapted to mesh With the rack gear while the meter is in operation, and means for moving the rack backvardly out of mesh with the rack gear when metering is to be avoided.

2. In combination with a float meter having a rack gear, two fixed upright parallel guides upon which the float meter rises and falls, an upright rack movably mounted between said guides and means for the rack baclnvardly to throw it out of mesh with. the rack gear and forwznfd into mesh again.

8. In combination with a float meter havinga rack gear, two fixed upright parallel moving guide bars upon which the float meter rises and falls, an upright rack movable between said guide bars, parallel oblique guides for said rack to permit its backward movement parallel with the guide bars and meung for producing said movement of the rack 4. In combination with a float meter having a rack gear, two fixed upright parallel guide bars upon which. the float meter rises and falls, a rack between [the guide bars having guiding means fixed to the guide bars and piercin the rack to permit simultaneous backwarc and upward movement of the rack, and means for so moving the rack.

In testimony whereof I have hereunto set my hand in presence of two snlmeribing Witnesses.
