LIQUID-MEASURING APPLIANCE.

Specification of Letters Patent.

Patented Aug. 19,1913.

Application led May 14, 1912. Serial No. 697,164.

To all w/om t may concern Be it known that I, CHARLES P. Ross, a citizen of the United States, residing at Seattle, in the county of King and State of lfVashington, have invented certain new and useful Improvements in Liquid-Measuring Appliances, of which the following is a speciiication.

The object of this invention is to simplify the construction and increase the efliciency of liquid measuring devices.

A further object of the invention is the provision of means for indicating and recording the number of measures of liquid drawn on'. Y

lVith these and other objects in view, as will appear from the following explanation of the invention, the same consists in the novel construction and combination of parts as will hereinafter be described and claimed.

The invention is illustrated in the accom.- panying drawings in which- Figure 1 is a view in transverse vertical section through a liquid measurer embodying the present invention. Fig. 2 is a longitudinal vertical section of the same but with the outlet valve shown open. Fig. 3 is a partial plan view with the detachable casing-cover removed. Fig. 4 is an underside plan view of the casing cover. A

The reference numeral 5 designates the casing of the device said casing being divided by a horizontal partition 6 to afford an upper chamber 7 and a lower chamber 8. This lower chamber is formed to be of a certain capacity, as for example one gill liquid measurement. At the bottom of such measuring chamber is an outlet opening) whereat is provided a discharge nozzle 10 having' formed therein a seat for a valve 11. Adjacent the top of the measuring chamber, the latter is provided with an inlet opening 12 communicating with the passage of a faucet body 13 which may be inserted in a bung hole of a cask, or other container, from which the liquid to be measured is to be drawn.

14 represents the plug valve of the faucet which is provided with a crank handle 14 extending forwardly above the casing, and which is also provided with an arm 15 which extends through Yan opening of the casing into the chamber 7, as shown in Figs. l and 2. The valve 11 is provided with a slotted stem 11 operating through a guide 16, and engaging within the stem slot is the lower end of a rod 17. This rod extends through 'a packing box 18 provided in said partition and thereabove itis connected by a pin 19 with an arm 20 of an angle lever whose other arm 20l is arranged to be engaged by the aforesaid arm 15 when the latter is swung through the agency of the handle 14 into position, toward the right in the illustrated example, which effects the closing of the faucet valve. Vhen the lever is thus engaged the rod 17 is influenced to raise the valve 11 from its seat for the discharge of liquid previously supplied to the chamber 8. When the crank handle is swung toward the left, the lever arm 20 is encountered and thrust downwardly by the handle tocorrespondingly lower the rod 17, whereupon the valve 11 closes and the faucet valve 14 is subsequently opened by the handle at or near the termination of the referred to movement. By such devices, it is seen that the liquid is admitted to the chamber 8 when the handle is swung in one direction and is discharged when the handle is swung in the contrary direction; but when the handle is in itsI medial position both of said valves are closed. Vhen the handle is, however, moved into position to canse either o-f said valves to `be opened or closed,

as the case/mayv be, mea-ns are provided to maintain them in such position until they have performed their respective functions.

That is to say, when the faucet valve 14 is opened it must remain in such condition until the measuring chamber is supplied with a predetermined quantity of liquid, thereupon the faucet valve may be closed and the discharge valve 11 opened and must thus remain until the liquid has been entirely discharged from said chamber. To accomplish such functions, there is provided in the chamber' 8, a float 21 operable upon an upright float rod 22 movable in a guide bracket 23 and through a tube 24 extending through partition G. Fixedly secured to the lioat rod are spaced collars 25 and-25 which are adapted to be encountered by the float as the latter is respectively'bo-rne upwardly by the liquid in the filling of the chamber and when the float is lowered by the withdrawal of the liquid. The' collar 25 is preferably of a conical form and constitutes in cooperation with the tube 24 an air valve.

The upper end of the float rod is connected by a pin 22 to one of the branches, as 26, of a bifurcat-ed arm of a controlling lever,

or controller, as it will hereinafter be called, which is provided in the chamber 7. The other branch 2G of said controller arm is inclined upwardly at its extremity for engagement by the valve arm 15 to be pushed down thereby near the termination of the right hand swinging movement of such arm to effect a downward movement of the floatrod carrying its collar valve 25 sufficiently for admit-ting air through the tube 24 into the lower chamber to replace the liquid escaping therefrom. Provided on said bifurcated arm of the controller is a lug27 whose office is to prevent the reverse movement of the arm 15 until the lug has been withdrawn through the instrumentality of the float 21 when the same descends upon collar 25 to exercise the power of its weight. Upon the arm 28 of the controller is another lug 27 which serves to prevent the arm 15 from being moved from the position it would assume when the faucet valve is open for filling chamber 8 with liquid.

29 is an arcuate rack ixedly secured to partition G in chamber 7 and is designed to coperate with a pawl 30 depending from the arm 15 to prevent the handle being swung in a retrograde movement until the arm 15 has been carried beyond either of the controller' lugs 27 or 27. More particularly, when the handle is swung in one direction or the other, the pawl engages the successive teeth of the rack and thereby prevents the handle being swung in a contrary direction until after the arm 15 has passed said lugs. The lugs then serve to prevent the arm or handle being moved bac-k until the measuring compartment has been filled with or emptied of liquid. l/Vhen this occurs the previously operative lug is, as before explained, withdrawn and the handle may be swung to the opposite side of the device while the pawl 30 is dragged, so to speak, over the rack though in position to prevent the return movement of the handle.

Included in the invention, are indicating devices to designate the number of times the measuring chamber has been successively utilized, as for example, where a number of measures of liquid is required to supply a sale. Such indicating devices may be of any suitable type, such as a wheel 31 to which is secured a face plate-31 having thereon spaced numerals and mounted upon an upright post 312 secured to the handle 14. Said wheel is provided with ratchet teeth 82 which are successively engaged by a pawl 33 secured to a pin extending upwardly from the cover 34 of the casing, and as the handle is swung toward the right the numbers of said face plate are in turn exposed through a sight opening 55 (Fig. 3) provided in a casing 55 which is rigidly secured to said post.

35 is a spring detent adapted to engage the Loc/der? ratchet teeth 32, as presented to obviate any accidental rotary movement to the wheel 31 opposite to that in which it is impelled by the pawl Supplementary indicating, or recording, devices are also desirably used within the chamber '7 and are most conveniently applied to the underside of the cover, see l `igs. 1 and 4. These devices may comprise a ratchet-wheel 3G mounted on an arbor 37 and actuated by a pawl 3S carried by the arm 15 to furnish a step by step rotary motion to the ratchet wheel during successive correspomlingly swinging movements of said arm toward the right. integral with said ratchet wheel is a gear 40 having a single tooth or spur 40 which engages in gullets provided about the circumference of a wheel 4l so as to give a partial turn to the wheel in each revolution of the gear spur 40. Upon the wheel 41 are graduated numbers 42 which upon being brought opposite to an index mark 43 provided on the cover, will designate the amount of liquid drawn from the liquid container', as will be understood.

45 represents the wall of a compartment 4G which is desirably provided interiorly of chamber 8 to accommodate the float 21, said conipartment having communication with the exterior' space in the chamber, by rela tively small holes 47 and 47 in said wall near the top and bottom of the same. Through the agency of these small holes, the compartment 46 will lill and empty more slowly than the surrounding space of eham, ber 8 and, in consequence, insures the re liable operation of the float controlled appliances.

To indicate to the operator when the chamber 8 has been charged with liquid, I provide an audible indicator which is actuated by a current of air flowing into the cash of' liquid container to replace the liquid as it is withdrawn therefrom. This indicator may consist of a vessel 49 which, as, shown in Fig. 2, is connected to the body of said faucet and communicates with the passage therein by a tube 50 which is bent to afford a downwardly directed extremity 50 within the vessel. Interiorly of such eX-I tremity is a seat 51 for a non return valve such as a ball 52. At the upper end of said vessel. is a pair of spaced diaphragms 53 provided with apertures 54 and constitutes a whistle whereby air flowing into the vessel` will generate a sound which will endure while the liquid is flowing from the container.

Having described the invention, what I claim, is-

1. In a liquid measuring device, the combination with a casing provided with a chamber having inlet and outlet openings, valves for said openings, means operable by a single instrumentality for successively opening said valves, and liquid controlled means for locking the aforesaid means during both the filling and emptying of the chamber and whereby the respective valves are prevented from being operated until the chamber is iirst filled with liquid and the same entirely withdrawn therefrom.

2. A liquid measuring device having a chamber provided with a valved inlet opening and a valved outlet opening, a single handle for operating the two valves, and means whereby the inlet valve upon being opened is maintained in such position until the chamber is filled, whereupon the handle may be moved to close the inlet valve and subsequently open the outlet valve, said means then acting to lock the valve in open position until the chamber is emptied.

3. A liquid measuring device, the combination of a casing provided with a measuring chamber having inlet and outlet openings, a valve for each of the openings, a means for effecting the alternate opening and closing of said valves, a controller for regulating the action of said means, a float, and operative connections between the floatand the controller whereby said controller is influenced to secure said means against valveaffecting movements during both the filling and emptying of the measuring chamber.

el. In a liquid measuring device, the combination with the casing provided with a measuring chamber having openings for the admission and discharge of liquid from the chamber, said chamber being also provided with an opening for the admission and discharge of air, a valve for each of said openings, of means for opening and closingthe valves of the two first named openings, a controller `for regulating the action of said means, a float, a float-rod connected to said controller, a valve rigidly connected to said rod and adapted to be operated to close or open t-he opening for air, and means provided upon the rod whereby the float engages the same to effect the movements to actuate said controller.

5. In a liquid measuring device, the combination with the casing provided with a measuring chamber having openings for the admission and discharge of liquid, a valve for each of said openings, of means for opening and closing the valves, a controller for regulating the action of said means, a ioat, a float-rod connected to said controller, an air valve rigidly connected to said rod and adapted to be operated to close or open the opening provided in said chamber, means provided upon the rod whereby the oat engages the same to effect the movement thereof which actuates said controller, and a tube surrounding said oat and provided with small perforations near the bottom and top of same.
