Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
A hose connector comprising: a couple of connecting plates each of which has a plurality of pipes integrally formed on one side thereof for connection to a plurality of hoses and a plurality of endless projections formed on the other side thereof, inner passages of said pipes running through said plate, said endless projections enclosing openings of said inner passages; a gasket between said connecting plates and having a plurality of apertures corresponding to said pipes, circumferential portions of said apertures being pressed by said endless projections for a perfect seal; a couple of plate retainers located on said connecting plates opposite to said gasket, each plate retainer having a plurality of apertures corresponding to said pipes to pass said pipes therethrough and having slight curvature for permitting the pressing of said connecting plates to said gasket by spring action; and means for pressing and flattening said plate retainers thereby fixing said connecting plates, gasket and plate retainers all together to connect said inner passages of said connecting plates to each other through said apertures of said gasket.
Claim 2
Dependent Claim
178 words
A hose connector comprising: a couple of connecting plates each of which has a plurality of pipes integrally formed on one side thereof for connection to a plurality of hoses and a plurality of endless projections formed on the other side thereof, inner passages of said pipes running through said plate, said endless projections enclosing openings of said inner passages; a gasket between said connecting plates and having a plurality of apertures corresponding to said pipes, circumferential portions of said apertures being pressed by said endless projections for a perfect seal; a couple of plate retainers located on said connecting plates opposite to said gasket, each plate retainer having a plurality of apertures corresponding to said pipes to pass said pipes therethrough and having slight curvature for permitting the pressing of said connecting plates to said gasket by spring action; and means for pressing and flattening said plate retainers thereby fixing said connecting plates, gasket and plate retainers all together to connect said inner passages of said connecting plates to each other through said apertures of said gasket.
Claim 3
Dependent Claim
179 words
A hose connector comprising: a couple of connecting plates made of hard plastic each of which has a plurality of pipes integrally formed on one side thereof, whose inner passages run through said plate, and has a plurality of circular projections formed on the other side of said plate for enclosing the openings of said inner passages; a gasket made of soft rubber and put between said connecting plates, and having a plurality of apertures corresponding to said pipes, whose circumferences are pressed by said circular projections to form a perfect seal; a couple of plate retainers made of steel and located on said connecting plates opposite to said gasket, each of which has a plurality of apertures corresponding to said pipes to pass them therethrough and has slight curvature for pressing said plates to said gasket by spring action, and a stud for pressing and flattening said plate retainers, thereby tightly connecting said connecting plates, gasket and retainers all together to connect said inner passages of said connecting plates to each other through said apertures of said gasket.
Claim 4
