An improved oiler includes a manually operated pump mechanism retained within the oiler container for pumping low viscosity oil and similar low viscosity fluids through a spout of the oiler for discharge by an adjustable spray nozzle. The nozzle is comprised of four separate interengaging parts including a compression fitting which contains a nozzle disc and a channel member. By rotating the compression fitting, physical separation of the disc and channel member is controlled and the pattern of spray through the nozzle is adjusted between a fine spray and a fine stream.
The invention describes a nozzle head for effectuating a broad angle cone of spray of liquid which liquid is contained in a tank and is forced into the nozzle head by pressure applied to the liquid contained in the tank.
A pump dispenser has a nozzle body on which is rotatably disposed a nozzle cap having two orifices which selectively align with a swirl chamber formed in the front end of the body. One orifice is formed with a surrounding cup-like structure to retain the last drop of liquid after discharge. The other is formed with a pair of diagonal parallel ribs on opposite sides of the orifice to effect an elongated narrow landing pattern for the spray.
A spray device for mounting on a fluid dispenser connected to a tank; the device being of the type comprising a head provided with an expansion chamber into which the outlet orifice of said dispenser opens out; the expansion chamber communicating with a nozzle via at least one outlet duct. The nozzle is constituted by a hinged inner element which is at least partially received in the outlet duct, and by an outer element fixed to bear in sealed manner against the inner element so as to define between their respective contacting surfaces a network of swirl-inducing channels communicating with the outlet duct and opening to the outside via a spray orifice formed through the outer element.
An atomizing nozzle usable on a vaporizer or atomizer is provided, having a unified core and valve member and a diaphragm perforated by a narrow orifice. The unitary member is axially mobile and laterally guided in a chamber within the nozzle. Additionally, the unified member has, on its end remote from the orifice, a concave circular cup in which the edges of the cup are turned toward the orifice, and, on its end nearest to the orifice, a core portion which cooperates with the diaphragm to form a system of turbulent channels which supply the orifice.
A container for a manually operable oil dispenser for use with metal working machines comprises a bucket providing a reservoir for oil to be dispensed and a pan in the bucket for catching oil and chips dropping thereinto and for returning the oil to the bucket. The bucket has a bottom, a sidewall and an annular upper end, and the pan has an apertured bottom spaced above the bottom of the bucket, a sidewall inwardly of the sidewall of the bucket and an upper end overlying and slidable circumferentially relative to the upper end of the bucket. The bucket and pan have locking members interengaging during relative sliding displacement therebetween to releasably interengage the bucket and pan against separation. The bottom and sidewall of the bucket are contoured to minimize the volume of oil necessary in the reservoir area for continual operation of the dispenser, and the bucket is provided with a bulkhead fitting for attachment to a dispensing pump hose at an angle of 45.degree. to horizontal.
