JOHN SULLIVAN AND WILLIAM ROSENSTOCK, OF THE UNITED STATES NAVY.

MEASURING APPARATUS.

To all whom it may concern:

Be it known that we, JOHN SULLIVAN and IVILLIAM ROSENSTOCK, of the United States Navy, citizens of the United States, have invented new and useful Improvements in Measuring Apparatus, of which the following is a specification.

The object of our invention is to provide an apparatus for measuring liquids, i. 6., for drawing off predetermined quantities of liq uid from a source of supply, which shall be exceedingly simple of construction and absolutely positive and efficient in operation.

The apparatus characterized by our invention isv most admirably adapted for use in saloons, but is, also, susceptible of advantageous use in grocery and other stores, and

V in wine-cellars of private houses.

By the use of the device of our invention in stores, saloons, and the like, considerable saving of time is effected, and the danger of overflow or withdrawal of more than the desired, predetermined quantity of liquid is obviated.

In drawing a desired predetermined quantity of liquid, in the use of our device, it is simply necessary for the Storekeeper, or the like, to place a bottle, can, bucket, or the like, beneath the spigot of our device, and, then, throw a lever, which is accomplished in a mere second of time, and which sets into operation automatically-operating mechanism; he can, then, immediately turn aside and wait upon customers and return to the apparatus to find the bottle, or the like, filled with the desired predetermined quantity of liquid, exit of the liquid having been automatically stopped at the proper time.

lVith the above objects in view, and others appearing as the specification proceeds, our invention comprehends the novel construction, arrangement, and combination of parts, as fully hereinafter described, set forth in the claims, and illustrated in the accompanying drawing, in which:

Figure 1 is a central, longitudinal sect-ion, partly broken away, through our apparatus, certain parts being shown in elevation; and Fig. 2 is a fragmentary, detail view, in front elevation, of the front wall of the casing.

Referring, now, in detail to the drawing: A designates a casing or housing, which may be of any desired shape, in this instance being shown as oblong. Extending preferably through the lower portion of the casing and Specification of Letters Patent.

Application filed April 13, 1910.

Patented Sept. 20, 1910. Serial No. 555,125.

longitudinally thereof is a pipe B, communicating, at one end, as at b, with a source of supply of liquid and carrying, at the other end, a spigot .7). Interiorly of the casin said pipe carries a valve or faucet Z2 controlling the passage of liquid through said pipe.

Interiorly of the casing A and mounted in suitable bearings in the front and rear walls, a a, respectively, thereof is a revoluble shaft C, preferably disposed toward the upper end of the casing. Carried by said shaft C, toward one end thereof, and movable therewith, is a gear 0, and secured to the other end of said shaft, as at c, is one end of a spiral clock-spring c of considerable strength, the other end whereof is secured to the rear wall a of the casing, as by the pin a.

The front wall a of the casing A is provided, toward its upper end, with an arcshaped slot a, in which works a pin 0, provided at the end thereof which is exterior of the casing with a knob or handle and secured at its other end to the gear 0. The exterior surface of the front wall a of the casing is provided, alongthe slot a with graduations and indicia a such as the numbers and words Pint Pint Quart etc. (See Fig.

Interiorly of the casing A and disposed beneath and parallel to the shaft C, and mounted in suitable bearings in the front and side walls a, a, of the casing, is another revoluble shaft D, carrying, toward one end, a pinion (Z, meshing with the gear 0. Also carried by said shaft D is a worm (Z.

Mounted on the stem of the faucet Z2 carried by the pipe B is a gear-wheel E, meshing with the worm d.

It will be seen, by the described construction and combination of the parts, that the farther the pin 0 is thrown, the more tightly will the spring 0 be wound up and, upon release of the pin, the greater will be the time the spring will take to unwind. Therefore, the operation will be apparent, but, briefly stated, it is as follows. The spigot Z) may be always left open, or be normally closed, and the faucet b is, of course, normally closed, cutting off communication through the pipe B. The relative size of the gear 0, the pinion the worm cl, the gear-wheel E, and the spring 0 is so proportioned and adjusted to the degree of velocity of flow of the particular liquid, under gravity or pressure, and

the consequent period of time a given quanl tity of the particular liquid must consume in passing through the faucet to the outlet spigot b, that, when the pin a is thrown from its normal position of inactivity at the end of the slot a to, say, the 1% Pint mark or graduation on the slot a the spring 0 will be so wound up that it will take a period of time to unwind sufficient to allow one-half pint of the particular liquid to pass through the faucet b to the exit spigot b. It will be understood that difierent liquids are of varying density, and that the velocity of flow thereof is governed partly thereby. Thus, the velocity of flow of molasses, being of considerable density, will be retarded, as compared, say, to that of wine of considerably lesser relative density; and the construction of our devices, under our invention, will, of course, be governed by the kind of liquid in connection with which they will be used. The pin 0 is thrown to the desired point, say to the T1; Pint mark on the arc-slot a and is, thereupon, immediately released: By the throw, mentioned, of the pin, the gear 0 will be rotated, the shaft C revolving simultaneously therewith and winding up the spring 0 the pinion d, being in mesh with the gear 0, will also be simultaneously rotated, revolving the shaft D and worm (Z coincidently therewith; the gear-wheel E, being in mesh with the worm 4, will also be synchronously revolved, thus turning the stem of the faucet b and opening the same, to allow flow therethrough of the liquid in the pipe B. As said, the pin is immediately released after throwing the same, whereupon the spring 0 which has been wound up by said throw of the pin will commence to unwind, thus reversing the prior direction of movement of the difierent parts and returning them to normal position, thus closing the faucet b and cutting off communication therethrough. It will thus be seen that the faucet b is automatically closed and the flow of liquid from the spigot Z) automatically stopped at the desired predetermined interval of time, requisite to withdraw the desired predetermined quantity of liquid.

It being understood that various slight changes in detail may be made without affecting the spirit of the invention, or sacrificing any of its advantages, and that all such modifications as come within the scope of the appended claims are within the purview of the invention, what we claim and desire to secure by Letters-Patent is:
