Abstract
Abstract A device for delivering a flow of matter in a variable direction, comprising an inlet piece and an outlet piece, said pieces being interconnected in a ball-jointlike manner in which the forces caused by the flowing pressure and tending to move the two pieces apart are compensated by a tie member disposed in the flow passage through and between the two pieces.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
258 words
A device for delivering a flow of matter in a variable direction comprising an inlet piece having supply-connecting means, and an outlet piece pivotally connected with said inlet piece, in which the interconnected ends of the two pieces have mating partially spherically shaped inner and outer surfaces respectively, a tie member being provided in the flowing passage between the two pieces, said member being connected to said outlet piece at a point adjacent the center of the common spherical surface, defining said inner and outer surfaces, and on the other hand being connected to a point of said inlet piece located upstream of said center, the inlet piece being mounted for an adjusting rotary movement about a vertical axis on a stationary connecting piece, characterIzed in that the inlet piece is carried out as a band, one axis of which is directed along the average elevation angle of the outlet piece, and the other axis of which is directed downward and has an axially directed collar enclosing an upper flange of said connecting piece and being supported by said flange with the intermediary of a ring of balls disposed in an annular track, defined by an outer circumferential groove of semicircular cross section in said flange and an opposite inner circumferential groove of semicircular cross section in said collar, said collar being provided with a hole, intersecting the inner circumferential groove in such a way, that the balls may be introduced in said annular ball track through said hole, said hole being filled up by a removable pin.
Claim 2
Independent Claim
258 words
A device for delivering a flow of matter in a variable direction comprising an inlet piece having supply-connecting means, and an outlet piece pivotally connected with said inlet piece, in which the interconnected ends of the two pieces have mating partially spherically shaped inner and outer surfaces respectively, a tie member being provided in the flowing passage between the two pieces, said member being connected to said outlet piece at a point adjacent the center of the common spherical surface, defining said inner and outer surfaces, and on the other hand being connected to a point of said inlet piece located upstream of said center, the inlet piece being mounted for an adjusting rotary movement about a vertical axis on a stationary connecting piece, characterIzed in that the inlet piece is carried out as a band, one axis of which is directed along the average elevation angle of the outlet piece, and the other axis of which is directed downward and has an axially directed collar enclosing an upper flange of said connecting piece and being supported by said flange with the intermediary of a ring of balls disposed in an annular track, defined by an outer circumferential groove of semicircular cross section in said flange and an opposite inner circumferential groove of semicircular cross section in said collar, said collar being provided with a hole, intersecting the inner circumferential groove in such a way, that the balls may be introduced in said annular ball track through said hole, said hole being filled up by a removable pin.
Claim 3
Dependent Claim
45 words
A device according to claim 1, characterized in that a cam lever is disposed between the collar and an intermediate flange of the connecting piece, said lever being adapted to exert an axial force tending to move the inlet piece and the connecting piece apart.
Claim 4
Dependent Claim
123 words
A water gun for fire extinguishing, comprising an inlet piece having supply-connecting means, and an outlet piece pivotally connected with said inlet piece, in which the interconnected ends of the two pieces have mating partially spherically shaped inner and outer surfaces respectively, a tie rod being provided in the flowing passage between the two pieces, having one end engaging said outlet piece along a partially spherical surface concentrically disposed with respect to the center of said mating partially spherical surfaces, and having its other end engaging said inlet piece at a point upstream of said center on the cam surface of a rotatable cam, said cam being provided with an external handle for rotating said cam to vary the tension in said rod.
Claim 5
Dependent Claim
123 words
A water gun for fire extinguishing, comprising an inlet piece having supply-connecting means, and an outlet piece pivotally connected with said inlet piece, in which the interconnected ends of the two pieces have mating partially spherically shaped inner and outer surfaces respectively, a tie rod being provided in the flowing passage between the two pieces, having one end engaging said outlet piece along a partially spherical surface concentrically disposed with respect to the center of said mating partially spherical surfaces, and having its other end engaging said inlet piece at a point upstream of said center on the cam surface of a rotatable cam, said cam being provided with an external handle for rotating said cam to vary the tension in said rod.
