Abstract
Abstract An easily installable, high load capacity deadending apparatus for securing the end of lines such as guy cables and the like to anchoring structure is provided which includes a tapered wedge block in conjunction with a helically preformed line tie adapted to grip the line and preferably extend around and engage the remote end of the wedge block for securing the latter against substantial axial movement; a socket casting having a complementally tapered bore is applied over the wedge block and line tie thereround to complete the apparatus and permit connection thereof to an earth anchor or like device so that the socket and block are biased together in mutual gripping interengagement. In practice, as the line experiences increasing tension loads, the wedge block and socket are pulled into tight interengagement which in turn causes a tighter grip of the line and increases the overall holding power of the deadending apparatus. This operation has been found to unexpectedly enhance the holding power of the present deadending apparatus as compared with conventional units. In alternative forms the wedge block is provided with a continuous, peripheral line-receiving groove or a central bore defined by opposed block sections for receiving and holding a line adjacent the end thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
231 words
Deadending apparatus for an elongated line or the like, including: an elongated, unitary, uniformly tapered block having structure defining three circumferentially spaced, peripheral grooves extending along the length of the block, one of said grooves being configured for receiving a segment of said line adjacent the end thereof with a portion of the line extending radially outwardly beyond the adjacent outermost surfaces of the block, the remaining two of said grooves being configured for receiving respective portions of a line tie; a line tie including a first section in gripping engagement with said line, and a second loop section free of said line, said loop section having respective elongated portions thereof received within corresponding line-tie receiving grooves of said block with a bight portion interconnecting said elongated portions and in engagement with the largest diameter end of said block, said line tie-receiving grooves being dimensioned such that said elongated portions are seated within the same without extending radially outwardly beyond the outer adjacent surfaces of said block; and a socket having structure defining a tapered bore therein for complementally receiving said block, the loop segment of said line tie positioned therearound, and the segment of said line received by said one groove, said socket and block cooperatively engaging said line, with the line tie portions seated within said remaining grooves being substantially free of pressing engagement between said socket and block.
Claim 2
Dependent Claim
231 words
Deadending apparatus for an elongated line or the like, including: an elongated, unitary, uniformly tapered block having structure defining three circumferentially spaced, peripheral grooves extending along the length of the block, one of said grooves being configured for receiving a segment of said line adjacent the end thereof with a portion of the line extending radially outwardly beyond the adjacent outermost surfaces of the block, the remaining two of said grooves being configured for receiving respective portions of a line tie; a line tie including a first section in gripping engagement with said line, and a second loop section free of said line, said loop section having respective elongated portions thereof received within corresponding line-tie receiving grooves of said block with a bight portion interconnecting said elongated portions and in engagement with the largest diameter end of said block, said line tie-receiving grooves being dimensioned such that said elongated portions are seated within the same without extending radially outwardly beyond the outer adjacent surfaces of said block; and a socket having structure defining a tapered bore therein for complementally receiving said block, the loop segment of said line tie positioned therearound, and the segment of said line received by said one groove, said socket and block cooperatively engaging said line, with the line tie portions seated within said remaining grooves being substantially free of pressing engagement between said socket and block.
Claim 3
Dependent Claim
27 words
Apparatus as set forth in claim 1 wherein said block is configured to present a groove in said largest diameter end thereof for receiving said bight portion.
Claim 4
Dependent Claim
46 words
Apparatus as set forth in claim 1 including structure defining a pair of apertures in said socket on opposite sides of said tapered bore for receiving the arms of a U-bolt, the latter having an intermediate section between said arms adapted for connection to anchoring means.
Claim 5
Dependent Claim
160 words
Deadending apparatus for an elongated line or the like including: an elongated, tapered block; a socket having structure defining a tapered bore therein for complementally receiving said block, said block and socket being cooperatively configured to present a line-receiving opening therebetween for receiving said line adjacent the end thereof in a manner such that said block and socket cooperatively engage the line, said block also being configured to present a pair of line tie-receiving openings along the length thereof; a line tie including a first section in gripping engagement with said line, and a second loop section free of said line, said loop section having respective elongated portions thereof received within corresponding line tie-receiving openings with a bight portion interconnecting said elongated portions and in engagement with the largest diameter end of said block, said elongated portions being of a diameter to be received within said openings therefor and be substantially free of pressing engagement with said block and socket.
Claim 6
Dependent Claim
160 words
Deadending apparatus for an elongated line or the like including: an elongated, tapered block; a socket having structure defining a tapered bore therein for complementally receiving said block, said block and socket being cooperatively configured to present a line-receiving opening therebetween for receiving said line adjacent the end thereof in a manner such that said block and socket cooperatively engage the line, said block also being configured to present a pair of line tie-receiving openings along the length thereof; a line tie including a first section in gripping engagement with said line, and a second loop section free of said line, said loop section having respective elongated portions thereof received within corresponding line tie-receiving openings with a bight portion interconnecting said elongated portions and in engagement with the largest diameter end of said block, said elongated portions being of a diameter to be received within said openings therefor and be substantially free of pressing engagement with said block and socket.
