Abstract: A fluid dispenser includes an actuator containing fluid passages defining a discharge path for fluid from a supply container to a discharge orifice, a needle valve lying adjacent the discharge path, a nipple surrounding the needle valve and a nozzle cap having an end wall containing a discharge orifice and being threadedly engaged with the nipple for movement of the end wall toward and away from the valve upon cap rotation. Discharge through the orifice may be positively shut-off upon rotation of the cap which causes the valve to be seated against the discharge orifice, and the nozzle cap may be locked in an off position upon engagement between a spring biased tab provided on the actuator and an inwardly extending shoulder provided on the skirt of the cap. A ramp member on the cap includes a ramp surface and the shoulder so as to effect inward deflection of the tab upon engagement with the ramp surface during cap rotation toward the off position.
Abstract: An improved high speed egg grading system wherein a pair of opposed lifting bars disposed on rotating rings transfer eggs over a plurality of weighing stations, and a conveyor belt is provided for removing graded eggs spaced two abreast. An improved drive is provided for the bars which insures gentle pick-up and set down of the eggs at weighing stations where scales incorporating damping means to reduce settling out time are located.
Abstract: An easily assembled poultry cage system wherein the framework for the system includes a plurality of spaced A-frame members all of which are adapted to be assembled without the use of conventional fasteners. Protrusions and complementary receptacles are utilized for joining, connecting and interconnecting parts of the system. Once assembled into the appropriate receptacle, the protruding member is deformed in a manner to securely fasten the respective members together. The cages are supported between A-frame members by means of wire supports secured to the A-frames, by interconnection of the cages and by means of the feed trough. The feed trough is supported by a clip member in which it is secured by a snap-fit to the spaced A-frame members.
Abstract: In a feed supply system in which feed from a hopper is directed into down spouts by means of augers, agitators, gravity feed or the like, the down spouts terminating at a feed trough, a sensor capable of sensing a build up of feed is disposed at the end of the down spout and supplies a signal to terminate dispensing when excess feed is sensed.
Abstract: An egg packer in which the eggs are aligned while being conveyed to a transfer position with the eggs thereat having their narrow ends in an abutting relation with a transversely disposed vertical wall. A receptacle is disposed adjacent the end of the conveyor into which the eggs are guided with the larger end of the egg first entering into the receptacle. Upon rotation of the receptacle, the egg is turned and assumes a position with the narrow end facing downwardly. A pair of shell members receive the egg and move it into alignment with the egg carton or other receiving means at which the shell members are opened and the egg is deposited with the narrow end thereof downwardly facing.
Abstract: A dispensing pump of the pressure build-up variety includes a cylinder defining a variable volume pump chamber, and a main piston reciprocable therein, the piston having a valve seat thereon communicating with a discharge passage leading to a discharge nozzle. A valve member having a smaller diameter piston thereon is moved during pressure build-up away from the seat for opening the discharge passage. The smaller diameter piston has a flexible peripheral wall which is deformed inwardly at the commencement of the piston downstroke for closing a flow passage in the smaller diameter piston and thereby interrupting communication between the inlet and the pump chamber, such flow passage being open upon outward movement of such peripheral wall at the end of the piston upstroke. At the top of the cylinder along which the smaller diameter piston moves is a relieved section effecting the opening of the flow passage in an inoperative condition of the pump.
Abstract: An article inflating system for engaging and inflating articles to be decorated is disclosed. A plurality of spaced cup-shaped nozzles are disposed on a horizontal moving endless belt so as to allow the cup-shaped nozzles to engage the article prior to decoration and assume a sealed relation therewith while passing through the decorating station. While at the decorating station, the open end of the cup-shaped nozzle is positioned in communication with an air supply manifold disposed adjacent the decorating station to enable inflation of the article during decorating. After the label has been applied to the article, the nozzle is gradually lifted out of engagement with the decorated article while the latter is conveyed away from the decorating station.
Abstract: A fluid dispenser has a discharge path outletting at a discharge orifice provided in a nozzle cap in engagement with a nipple surrounding a dispenser needle valve, the cap being adjustable axially of the needle valve so as to move an open ended swirl chamber, which surrounds the discharge orifice, relative to the needle valve into and out of engagement therewith. The fluid is emitted from the discharge orifice in a concentrated and linear pattern upon disengagement between the swirl chamber and the needle valve. Otherwise, upon movement of the cap until the needle valve plugs the open end of the swirl chamber, a shaped spray pattern is created through the discharge orifice. The orifice is defined by a circular wall and by a pair of opposed projections thereon, the projections extending inwardly of the orifice and having spaced apart ends so as to effect a substantially flat spray pattern through the orifice when movement of the cap toward the needle valve causes the valve to plug the swirl chamber end.
Abstract: An egg drying apparatus is disclosed incorporating an improved laminar air flow for more effectively drying eggs. The orifices for discharging and directing air towards the eggs to be dried have a coefficient of discharge of at least about 0.8. The orifices are disposed in the bottom of a chamber and are formed by adjacently spaced elongated members having curved air contacting surfaces along the longitudinal axis of each member. A fan draws air into the chamber which is directed towards the eggs via the orifices. In the preferred embodiment, the coefficient of discharge of the orifices is about 0.9 and curved portions of the elongated members are U-shaped channels with the exterior of adjacent channels forming the orifices.
Abstract: A liquid dispenser has relatively rotatable closure, sleeve and plunger members, the latter two being locked against reciprocation of the plunger member by a misalignment between ribs and grooves therebetween. One of the grooves has a pair of upstanding pegs on opposite sides so as to not only avoid inadvertent alignment when the ribs and grooves are in a misaligned position, but to also permit the plunger and sleeve members to rotate together as the rib abuts against one or the other of the pegs when in a misaligned position. A spacer element surrounding the plunger rod maintains the inlet valve in a closed position despite a slight separation between the plunger and sleeve members when rotated to the misaligned position. Also, the closure member is adapted to be removed only with difficulty from the container on which it is affixed.
Abstract: A throw-away, one-use tray, for the packaging of easily bruised fruit and produce in conjunction with an overwrap plastic film, is provided with an open-window bottom configuration in which the bottom ribs defining the open windows are approximately 20% greater thickness than the side walls of the tray. The rib form at the bottom serves the functions of stiffening the bottom more than would ribs resulting from die cut openings, and creating a smooth rolled edge in contact with the produce to reduce cutting and bruising.
