Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 423 words
An improved compression type end fitting for plastic jacketed cables through which fluid mediums pass comprising: a. a central body portion having a central bore extending in a longitudinal direction partially therethrough and adapted to receive the end of said cable in order to allow compression of said central body portiOn about the end of said cable to secure said end fitting to said cable; b. a sleeve means surrounding said central body portion and spaced from said body portion at least in contiguous portions extending from a point extending on one end beyond said central body portion and on the other end abutting and sealingly secured to said body portion, c. a sealing fitting means positioned at the end of said sleeve means extending beyond said central body portion arranged and constructed to effect a sealing relationship with both the surface of said cable and the sleeve means; and d. a passage means positioned in the opposite end of said central body portion from said bore and extending from a location in the central body portion adjacent to which the sleeve means is spaced from said body portion to the terminal end of said end fitting, said passage means opening into the space between the said sleeve and the central body portion at one end and to the exterior of said end fitting at the opposite end and in part defining a portion of a continuous passage extending from a position adjacent an opening in the jacket of a plastic jacketed cable secured in said end fitting - said opening being intermediate the sealing fitting means and the end of the central body portion - longitudinally between the said sleeve means and the said central body portion, and then through the portion of said central body portion beyond the end of said central bore in said central body portion to the end of the fitting, said end fitting being so constructed and arranged that a fluid medium, passing into the upper portion of a plastic jacketed cable, secured in said end fitting, and flowing therethrough along and around the component wires of said cable, will flow from the interior of said cable, through the opening in the plastic jacket, into and through the space between the central body portion and the sleeve means, thence through passage means in the portion of the central body below the end of the central bore therein and therethrough to the exterior of the terminal end of the central body portion which extends beyond the sleeve means.
Claim 2
Dependent Claim 423 words
An improved compression type end fitting for plastic jacketed cables through which fluid mediums pass comprising: a. a central body portion having a central bore extending in a longitudinal direction partially therethrough and adapted to receive the end of said cable in order to allow compression of said central body portiOn about the end of said cable to secure said end fitting to said cable; b. a sleeve means surrounding said central body portion and spaced from said body portion at least in contiguous portions extending from a point extending on one end beyond said central body portion and on the other end abutting and sealingly secured to said body portion, c. a sealing fitting means positioned at the end of said sleeve means extending beyond said central body portion arranged and constructed to effect a sealing relationship with both the surface of said cable and the sleeve means; and d. a passage means positioned in the opposite end of said central body portion from said bore and extending from a location in the central body portion adjacent to which the sleeve means is spaced from said body portion to the terminal end of said end fitting, said passage means opening into the space between the said sleeve and the central body portion at one end and to the exterior of said end fitting at the opposite end and in part defining a portion of a continuous passage extending from a position adjacent an opening in the jacket of a plastic jacketed cable secured in said end fitting - said opening being intermediate the sealing fitting means and the end of the central body portion - longitudinally between the said sleeve means and the said central body portion, and then through the portion of said central body portion beyond the end of said central bore in said central body portion to the end of the fitting, said end fitting being so constructed and arranged that a fluid medium, passing into the upper portion of a plastic jacketed cable, secured in said end fitting, and flowing therethrough along and around the component wires of said cable, will flow from the interior of said cable, through the opening in the plastic jacket, into and through the space between the central body portion and the sleeve means, thence through passage means in the portion of the central body below the end of the central bore therein and therethrough to the exterior of the terminal end of the central body portion which extends beyond the sleeve means.
Claim 3
Dependent Claim 66 words
An improved end fitting according to claim 1 wherein the sleeve means is an annular sleeve means and is secured at the end extending beyond the central body portion to the sealing fitting means in which there is positioned a packing means adapted to be compressed against the outer surface of the plastic jacket by a gland means to effect a seal with said plastic jacket.
Claim 4
Dependent Claim 35 words
An improved end fitting according to claim 2 wherein the end of the annular sleeve abutting said body portion is threaded and adapted to engage threads upon said body portion to effect a seal therewith.
Claim 5
Dependent Claim 45 words
An improved end fitting according to claim 3 additionally comprising packing means adjacent a flange on the body portion against which the annular sleeve means is adapted to be threaded, said packing means effecting a seal between said annular sleeve and said central body portion.
Claim 6
Dependent Claim 40 words
An improved end fitting according to claim 4 wherein the end fitting has a threaded nose adapted for threaded engagement with additional apparatus and through which fluid passage means extends to conduct fluid from said fitting to said additional apparatus.
