UNITED STATES PATENT OFFICE FEEDER PAIL VALVE ASSEMBLY James M. (Joyner, Madison, Wis.
Application April 22, 1949, Serial No. 89,078
3 Claims. (Cl. 119-71) This invention relates to a feeder pail valve and method of assembly. The invention is applicable to other pails using a check valve in the nipple assembly, etc.
An object of the invention is to provide a feeder pail with a metal flap valve which permits complete drainage of the fluid from the pail. Yet another object is to provide a feeder pail with a half-moon opening in the outlet ferrule of the structure and with a flap valve designed tocontrol the flow through such half-moon opening. Still another object is to provide an outlet ferrule in combination with a metal flap valve which may be inserted in bent shape and then readily restored to a straight-line structure. Yet another object is to provide a new method for assembling a flap valve within a tube. Other specific objects and advantages will appear as the specification proceeds. I
The invention is illustrated in a single embodiment, by the accompanying drawing, in which-- Figure 1 is a perspective view of a pail equipped with the valve structure embodying my invention; Fig. 2, an enlarged, broken sectional view showing the ferrule and valve therein; Fig. 3, a view of the outlet tube or ferrule and of the opening provided in the partition in the ferrule; Fig. l, a sectional detailed view, the section being taken as indicated at line 4-4 of Fig. 2; Fig. 5,
a detailed sectional view, the section being taken as indicated at line 55 of Fig. 4; Fig. 6, a side view in elevation of the outlet thimble or ferrule; Fig. '7, an enlarged view similar to Fig. 4 but showing the flap valve in bent position prior to the straightening of the valve in position; Fig. 8,
a view similar to Fig. 7 but showing the completion of the assembly step in which the flap valve is straightened, with the pivot ears thereof received within openings in the ferrule; Fig. 9, a perspective view of the flap valve in bent position and prior to final assembly; and Fig. 10, a perspective view of the flap valve in the shape that it exists after assembly.
In the illustration given, I designates a pail which may be equipped with a bail I I. The pail may be formed of metal or any other suitable material. The pail is provided near its bottom with an opening through which extends an outlet tube or ferrule I2. The ferrule is preferably provided with a collar I3, which sits against the inner wall of the pail and which may be secured thereto by solder, or other means.
The tube or ferrule I2 is provided interiorly with a partition wall I4, having an opening I formed in the lower portion thereof generally in 2 the shape of a half-moon, as shown best in Fig. 3.
To control the flow outwardly through the half moon opening I5, I provide a flap valve IS. The flap valve is preferably in the shape of a halfmoon but slightly larger than the opening I5, and is equipped with laterally-extending pivot ears I1. The cars II extend through openings II on opposite sides of the tube or ferrule I2.
I find that the flap valve I6 can be effectively and quickly assembled within the ferrule [2 by bending the metal flap valve It to the position shown in Fig. 9 and inserting it, as illustrated in Fig. 7, until the ears l1 are in line with the openings I8. At this point, the inwardly-extending flange I9 about the lower portion of the halfmoon opening I5 engages the peripheral portions of the valve l6 and serves as an anvil to support the bent structure when a punch is introduced through the open end and against the apex portion of the bent valve [6. As the punch is advanced toward the flange 19, the flap valve I6 straightens to the position shown in Fig. 8, so that the valve I 6 is thus permanently anchored in position, with the ears I! thereof engaging the openings l8.
Upon the ferrule I2, as thus secured within the pail and equipped with the flap valve I6, I draw a resilient nipple 20 of the usual type used in feeder pails and provided with the usual dispensing slit in the outer end thereof. Milk, or other feeding material, including semi-solid feeds, may be placed within the pail and the pail suspended upon a support, so that the calf may have access to the nipple 20. While the calf is sucking upon the nipple 20, the valve I 6 is effective in permitting the flow of liquid or semi-solid liquid into the nipple 20, while at the same time preventing back flow into the pail.
The flap valve I6 does not gum up when semisolid materials or semi-fluid materials are fed in the form of a suspension through the pail as is the case when a ball-type of check valve is used. Further, the half-moon opening I5 reaches to the lowest part of the valve l5 and the flap valve permits complete drainage of the fluid from the pail.
The method of assembly of the flap valve within the ferrule permits ready and accurate assembly, while at the same time resulting in a permanently formed flap valve which will not become detached from its engagement with the ferrule. The projections or ears I! of the valve are forced by the punch into the sockets or holes [8, while the punch takes the bend out of the distorted flap valve, the flanges of the partition. wall l4 serving as an anvil to hold the distorted flap valve while it is made straight.
While, in the foregoing specification, I have set forth a specific structure in considerable detail for the purpose of illustrating one embodiment of the invention, it will be understood that such details of structure may be varied widely by those skilled in the art without departing from the spirit of my invention.
1. A valve assembly adapted for attachment to a feeder pail equipped near its bottom with an opening, comprising a flanged ferrule adapted to extend through said opening and provided with a partition wall extending interiorly across the ferrule passage, said partition wall being provided in its lower side with an opening, a flap valve of malleable metal extending across said opening on the outer side of said partition wall and equipped with laterally-extending projections, said ferrule being provided in its side walls with openings receiving said projections, and a resilient conduit carried by said ferrule and enclosing said wall openings.
2. A valve assembly adapted for attachment to a feeder pail equipped at its bottom with an opening comprising an outlet tube adapted to extend through said opening and to be secured to a pail, said tube having a partition Wall extending across its interior and provided in the lower portion thereof with an opening which is generally of a half-moon shape, a flap valve of malleable metal substantially filling the lower half of the tube and closing said opening, said valve having laterallyextending projections, said tube being provided with diametrically arranged openings receiving said projections, and a conduit secured to said tube and extending over and enclosing said openings.
3. A valve assembly adapted for attachment to a feeder pail provided near its bottom with an opening, comprising a flanged tube adapted to extend through said opening, means adapted to unite said flange to the inner wall of a pail, said tube having a substantially imperforate wall ex-- tending across the upper half of said tube on the interior thereof, the lower half of said tube being open, said tube having openings in the sides thereof adjacent the lower ends of said partition wall, a, half-moon shaped malleable metal flap valve having laterally-extending projections received within said openings, and a resilient conduit engaging the outer surface of said tube and closing said side wall openings.
