MEASURING-FAUCET.

SPECIFICATION forming part of Letters Patent No. 592,274, dated October 26, 1897.

Application filed March 31, 1896. Renewed March 3, 1897. Serial No. 625,913. (No model.)

To all whom it may concern:

Be it known that I, ERNEST BOENING, a c'it-i-- zen of the United States, and a resident of Yonkers, in the county of Westchester and simple, cheap, and reliable measuringfaucet,

for drawing liquids from any source, but especially for application to wagon-tanks, and being provided with a registering apparatus whereby the indication of the quantity to be drawn is made before the drawing to prevent I 5 drawing without showing the evidence thereof, and the "apparatus may be effectually locked to prevent undue working of the register and to prevent it from being shifted by the shocksand jars of the wagon, as hereinafter described, reference being. made to the accompanying drawings, in which- Figure 1 is a transverse sectional elevation of the apparatus and part of a wagon-tank. Fig. 2 is a front elevation of the apparatus 2 5 shown in Fig. 1, with a part in sectional elevation. Fig. 3 is aside elevation on a reduced .scale. Fig. 4: is a front elevation, and Fig. 5 is a side elevation, of the apparatusin'a modified form of construction; Fig. 6 is an eleva tion of the registering apparatus in same view as in Fig. 2, but enlarged for greater clearness.

Fig. 7 isa section of the apparatus of Fig. 6 on line a z.

A represents the wagon or other tank from which the liquid is to be drawn.

' b and 0 represent measuring-chambers located side by side and separated by a partition d, two chambers being used to facilitate delivery by drawing into one chamber while: These measurdischarging from the other. ing-chambers are in this example represented as formed in an integral casting of metal; but they may be otherwise constructed, as 'desired. They are joined to the under side of 5 the tank A by a neck-piece e, in which is a taper-plug valve f, above said chambers, and having a straightway port g, with which two tank-ports h and "J communicate, respectively, according as the valve is set; but a single wide port may be used; and chamber 1) has a port j, and chamber 0 a port k, which also respectively communicate with valveport g, according totheposition ofthe valve, said ports j and It being separated by the partition d. The Valve also has vent-ports Z and m, respectively communicating with small air-inlet passages at when the chambers are opened for discharge of the contents and being closed when the chambers are filling.

In the lower extremity of the measuring chambers is another plug-valve 0, having a straight passage 19, with which ports (1 and s of the chambers communicate, respectively, according as the valve is set for discharging the measured contents into the nozzle t for delivery to the receptacle into which the liquid is to be drawn. The projecting stems of these two valves are geared together in front of the measuring-chambers by toothed segments to for synchronous action, and one is provided with a crank p for operating them, the arrangement being such that when, after one chamber has filled and the other has emptied,valve f is shifted for again filling the empty chamber, valve 0 will be shifted for opening the discharge-passage of the filled chamber, and so on.

'As it is not feasible to cast the chambers :with sufiicient accuracy of size for the necessary exactness of measurements of quantity, 8o

they are each cored or otherwise formed, as at w, for reception of an adjusting-plug m, by which any inaccuracy may be corrected by screwing the plug in or out.

The segments u are formed with eye-ter-- minals y at their extremities, so arranged that when the limit of movement of the valve is reached the eyes of those extremities that are I in mesh will match by overlapping each other and together form a double eye, whereby the 0 valves maybe locked in position with the 'hasp z of a padlock a inserted through said double eye to prevent unauthorized use of the faucet in the absence ofthe attendant and also to prevent the valves from shifting by 5 the shocks and jars of the wagon when mov-. ing along-the street. This lock 'alsoyserves to lock the registering apparatus to prevent making false registry. To illustrate this part of the invention, it is only necessary to show Ioo the prime mover of a register with my improved appliances for working it, as the rest of the register may be of any approved form. The said prime mover consists of the ratchetwheel a fixed loosely on a stud-pivot b of the back plate 0 of a case (1 and coincident with the axis of the valve f, said case being supported in front of the end of said valy e in any approved way,as by bracketc. Behind the back plate 0 of said case is a wrist-pinf, either in the crank V or in the end of one of the valves, which is connected by a rod or link g with a sliding pin 71 in a slot 2" of the back plate radial to the stud Z) and forming a pivot on which a hook-pawl It" is carried for shifting the ratchet-wheel a stage at each movement of the valves. A coiled spring Z, fixed on a curved rod m and bearing againstthe back of pawl 7t, keeps the pawl in engagement with the teeth of the ratchet-wheel and tends to shift the pawl back to the normal position. A retaining-pawl n. is employed, as usual, to prey'ent back motion of the ratchet when the shifting-pawl It returns after shifting the ratchet.

On the hub of the pawl it, connected to the sliding pin 71., is a locking-spur o, facing the ratchet-wheel and in such relation that it looks the ratchet-wheel until pawl /t is shifted for turning said wheel, and when the pawl it returns to normal position after shifting the ratchet it engages said ratchet again and effectually prevents it from shifting until the valves are again shifted, its movement being dependent on the movement of the valves, and when they are locked the registering apparatus is thereby also locked.

How the movement of the register is effected so that the drawing will be indicated before the liquid is drawn will be understood by reference to the diagram Fig. (5, where it will be seen that a movement of the crank r for -shifting the valves in one direction imparts through said wrist-pin a forward-and-backward movement to the sliding pin 71" and the pawl 7t, whereby the pawl shifts the ratchet in the first half of the movement of the crank, which is before the valves open, and returns to the normal position and locks the ratchet in the last part of the movement of the crank and simultaneously with the opening of the valves, this being effected by the connection of the sliding pin with the wrist-pin, so that said wrist-pin crosses the radial line in which the pin 71" slides when the crank r is at the middle of its stroke.

The valve-casings are prcferablycast integral with the chamber-casting, as shown in Fig. 1, but they may be made separately and be attached, if desired.

Figs. I and 5 show the chamber-casting in a different form, which may be preferred in some cases as more favorable for rapid and complete discharge of the contents, as when a wagon-tank may happen to stand on a grade with the hind end upward, and plug-valve o is represented with a branched passage with the nozzle having but a single port; but these changes are immaterial.

The register-supportingbracket may be attached to the measuring-ehamber casting instead of the tank, if desired.

It is to be understood that the chambers vent, when filling into the tank, through valve 1'.

To facilitate keeping accounts of drafts when a number are made in succession, I will provide a circle of plug-holes q in the cover of the dial and the indicator-hands with a plug a to be set prior to the first draft as far ahead of the hand as the number of drafts to be made to show when the hand reaches the plug the completion of the intended number of drafts.

The front plate of the register-case (Z will preferably be of metal, with openings (1 for sight of the indicator-hand, and on the lower edge of said front plate I provide a radiallyprojecting extension 6 with a guard f on the crank 1: overlapping said extension of the plate at the front, which guard being securely fastened to the crank will prevent the plate from being removed and protect the indicator from being fraudulently shifted to make false registry.
