Abstract
Abstract The present invention is directed to a specialized hose end connector utilized for connecting a hydraulic hose dimensioned according to a first industry standard to a hydraulic port dimensioned according to a second industry standard. As one example meant for illustrative purposes only, the specialized hose end connector can secure a SAE Code 61 dimensioned hydraulic hose to a SAE Code 62 dimensioned hydraulic port. The specialized hose end connector eliminates the need for prior art adaptor plates and requires no extra labor steps or sealing surfaces than normally encountered in standard hose end connectors.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
97 words
A connector for connecting a fluid conduit of a first code standard to a fluid port of a second code standard different than said first code standard and wherein said fluid conduit has a flange head dimensioned according to said first code standard, said fluid port is dimensioned according to said second code standard, said connector having an opening dimensioned according to said first code standard for receiving said fluid conduit flange head, and said connector having securing means positioned according to said second code standard and being adapted for connecting said connector to said fluid port.
Claim 2
Dependent Claim
97 words
A connector for connecting a fluid conduit of a first code standard to a fluid port of a second code standard different than said first code standard and wherein said fluid conduit has a flange head dimensioned according to said first code standard, said fluid port is dimensioned according to said second code standard, said connector having an opening dimensioned according to said first code standard for receiving said fluid conduit flange head, and said connector having securing means positioned according to said second code standard and being adapted for connecting said connector to said fluid port.
Claim 3
Dependent Claim
44 words
The connector of claim 1 wherein said connector is formed by a pair of split flange clamp halves each having a semi-circular recess which together with the semi-circular recess of the other clamp half forms said connector opening receiving said fluid conduit flanged head.
Claim 4
Dependent Claim
64 words
The connector of claim 2 wherein each clamp half has at least two bolt receiving openings spaced according to the dimensions of said second code standard for said fluid port, and said securing means comprising bolts passing through said bolt receiving openings and into bolt receiving apertures formed in conjunction with said fluid port in accordance with the specifications of said second code standard.
Claim 5
Dependent Claim
30 words
The connector of claim 3 wherein the semi-circular recesses are dimensioned in accordance with SAE Code 61 and said bolt receiving openings are positioned in accordance with SAE Code 62.
Claim 6
Dependent Claim
161 words
A split flange connector adapted to secure a fluid conduit flange head configured according to a first code standard to a hydraulic port configured according to a second code standard different than said first code standard and wherein said split flange connector consists of a pair of split flange clamp halves each having a semi-circular recess adapted to mate with a portion of a flange head and having internal dimensions in accordance with said first code standard, each of said clamp halves also having a pair of bolt receiving opening which are spaced according to the dimensions required by said second code standard whereby a fluid conduit flange head dimensioned according to said first code standard can be directly mounted on a hydraulic port dimensioned according to said second code standard and secured by bolts passing through said bolt receiving opening in said clamp halves into bolt receiving apertures formed at said hydraulic port in accordance with said second code standard.
Claim 7
Dependent Claim
161 words
A split flange connector adapted to secure a fluid conduit flange head configured according to a first code standard to a hydraulic port configured according to a second code standard different than said first code standard and wherein said split flange connector consists of a pair of split flange clamp halves each having a semi-circular recess adapted to mate with a portion of a flange head and having internal dimensions in accordance with said first code standard, each of said clamp halves also having a pair of bolt receiving opening which are spaced according to the dimensions required by said second code standard whereby a fluid conduit flange head dimensioned according to said first code standard can be directly mounted on a hydraulic port dimensioned according to said second code standard and secured by bolts passing through said bolt receiving opening in said clamp halves into bolt receiving apertures formed at said hydraulic port in accordance with said second code standard.
Claim 8
Dependent Claim
100 words
The split flange connector of claim 5 wherein said hydraulic port is formed in a hydrostatic transmission unit having a maximum pressure rating of a first predetermined pressure establishing the requirement for hydraulic ports in said transmission unit being dimensioned according to said second code standard and wherein said transmission unit is connected in hydraulic circuit by fluid conduits consisting of hydraulic hoses at a lower pressure rating and manufactured in accordance with said first code standard, said split flange connector securing the flanged head of one of said hoses to one of said hydraulic ports of said transmission unit.
Claim 9
Dependent Claim
70 words
The split flange connector of claim 6 wherein said hydraulic port and the size and placement of said clamp half bolt receiving openings are dimensioned according to SAE Code 62 standards and said flanged head and said semi-circular recesses of said clamp halves are dimensioned according to SAE Code 61 standards whereby a lower psi rated hose is connected to a 6,000 psi rated port by said split flange connector.
