MEASURING AND FILLING APPARATUS.
SPECIFICATION formi-ng part of Letters Patent No. 71 1,144, dated October 14, 1902.
Application filed March Il, 1902. Serial No. 97,710. (No model.)
To a/ZZ whom t may concern:
Be it known that I, ALLEN CHUEN WEIGHT, a citizen of the United States, residing at Berkeley, county of Alameda, State of California, have invented certain new and useful m r velnen sin easurinfr an i infr I o t M g dFll z,A
paratus; and I do hereby declare the following to be a full, clear, and exact description ot the same.
The present invention relates to a simple and eective device for measuring liquids,
such as syrup, and automatically discharg-` ing same for the filling of jars, cans, or packages, the object of the invention being to facilitate the handling of the material and filling of the cans, jars, or packages.
To comprehend the invention, reference should be had to the accompanying sheet of drawings, wherein- Figure 1 is a verticalsectional front view in elevation of the apparatus. Fig. 2 is a side View thereof. Figs. 3 and 5 are end views `of the cut-olf valve in the position indicated in Fig. 4. of the drawings. Fig. 4 is a longitudinal sectional View of the valve-casing with the valve therein. Figs. 6 and 8 are end views of the cut-oft' valve illustrated in Fig. 7; and Fig. 7 is a View similar to that of Fig. 4 of the drawings, the position of the valve being changed so as to illustrate the open ports of Fig.V 4.- as closed and the closed ports thereof as opened. I
In the drawings the numerals l 2 are .used
to indicate the syrup-cylinders, within which work, respectively, the pistons 3 4. The piston-stems 5 6 extend above or beyond the upper end of the cylinders, andthe inner edge or face of `each piston-stem near its upper portion is formed into a rack 7. These rack portions of the piston-stems engage or mesh with the rack-pinion 8, which pinion is journaled in bearings of upright 9. The cylinders are secured to the valve-casing 12, communication between the cylinders and the interior of the casing being established by ports 13 14, respectively, of the casing. This valvecasing is also provided with the outlets l5 16, located a short distance apart. Below the outlets l5 16 is located a supporting-shelf 17 for the jars or cans 1S to be filled. This supporting-shelf is secured to rod 19, which screws into base 20. The shelf maybe raised or lowered, so as to decrease or increase its distance from outlets l5 16, in accordance with the height of the jar or packageto be placed beneath the outlet for filling.
Within the valve-casing 12 is tted a rota- Itable valve 21, which valve is provided with the inlet and outlet ports a o. and b and b', which inlet-ports communicate, respectively, with the ports 13 and d and 14 and d. With :the port d communicates the supply-pipe 22, which leads from a reservoir located at any suitable place containing the liquid or syrup to be conveyed to the jars or packages to be llled. Port a ofthe valve is so arranged as to communicate with outlet l5 when registering iwith port 13, While port b' when registering `with port 14 communicates with outlet 1G. When port a is out of registry with port 13, g port b will communicate with port 14 and supply-port (l, opening communication between cylinder 2 and the supply-pipe 22. The turning of valve 2l so as to cut off port a and establish communication between cylinder l and supply-pipe 22 by placing port ain regislirry with ports 13 and d destroys communication between ports 14 and d through port b and establishes connection between outlet 16 and cylinder 2 through valve-port b', so as topermit the liquid in cylinder 2 to escapo outlet of cylinder 2 to receive same.
The iuid'or liquor from the Vreservoir is forced by its head-pressure through supply- Ipipe 22 and is admitted into one of the cylinders-say cylinder l-through inlet-port l` a. As the liquor is admitted into this cylin- -f der` it forces piston 3 upward, the stem 5 of which during its upstroke causes the rack- Ypinion S to rotate so as to force stem 6 and piston 4 of cylinder 2 downward. yDuring i the downstroke of piston 4 the liquor or fluid 4contained in cylinder 2 is forced therefrom and through valve outlet-port b/ into outlet 16, from which it escapes into the jar, vessel, or package resting thereunder to be iilled.
As the downwardly-moving piston l is about to complete its stroke arm d', projecting from one end of the rotatable valve 2l, is engaged by lower end of rod 23, secured at its upper therefrom into jar cr package located beneathy IOO end to piston-stem 6, and gradually forced downward so as to impart a quarter-rotation to the valve. This movement of the valve closes inlet-port a and outlet-port b', at kthe same time opening into port b and outlet-port a'. When the valve stands in this position, the liquor and iiuid from the supply-pipe will enter cylinder 2 through inlet-port b and forces piston fi and its stem 6 upward, so as to fill said cylinder with liquor to be forced therefrom during the next downstroke of the piston 4. During the upstroke of said piston the stem 6 imparts an opposite rotation to rack-pinion 8, the movement of which forces piston-stem 5 and its piston 3 downward within cylinder l. With this movement of the piston 3 the liquor or iiuid contained in cylinder l is expelled therefrom and through outlet-port a into outlet l5, from whence it escapes into the vessel, jar, or package located thereunder to receive same. As the piston 3 approaches its full downstroke lower end of rod 24 engages arm d2, projecting from opposite end of valve 2l as that of arm d', and gradually forces said arm downward, so as to impart a reverse quarter-rotation to the valve 2l, thereby closinginlet-port Z9 and outlet-port a and opening inlet-port d and outlet-port b. The operation of emptying cylinder 2 and filling cylinder l, before described, is again repeated. In order to render the rotatablevalve 2l evenly balanced, there is attached to each end of said valve balance weights or arms d3, which oppose arms d d2. It will thus be observed that the operation of illing and emptying the cylinders is entirely automatic, it only being required that an operator be employed to remove the lled vessels and replace same with ones to be filled.
The cylinders may be supported in any suitable manner. I have illustrated same as being attached to bracket 25, which in turn may be secured to a wall or other support.
When it is desired to discontinue the working of the apparatus, it is only required to cut off the supply of liquor or iuid lthrough thel supply-pipe. A suitable cock may be utilized for this purpose.
Having thus described the invention, what is claimed as new, and desired to be protected by Lett-ers Patent, is
l. In a measuring and filling apparatus, the combination with a pair of cylinders, pistons Working therein, a rotatable valve for controlling the admission of fluid into and from the cylinders, a supply-pipe communicating with the casing of the rotatable valve, communication between the cylinders and the interior of the valve-casing, outlet-ports in said casing, inlet-ports in the valve which alternately connect the cylinders with the supply-pipe, and outlet-ports in said valve which alternately connect the cylinders with the outlet-ports of the valve-casing, and connection between the pistons of the cylindery whereby as one piston is forced upward by the admission of fluid into its cylinder the opposing piston is forced downward to expel the contents of its cylinder.
2. In a measuring and filling apparatus, the combination with a pair of receiving-cylinders,of means whereby the cylinders are alternately connected with a supply-pipe, a piston workingin each cylinder, connection between the pistons so arranged that as one piston is forced upward by the pressure of the fluidY admitted into its cylinder the opposite piston is forced downward within its cylinder to ex pel the contents thereof, outlets for the cylinders, and valved outlets with which the outlets of the cylinders alternately communicate so as to permit of one cylinder exhausting while the other cylinder is being illed.
