Abstract
Abstract A dispenser for use in applying soap or other lubricants to wires to be pulled through conduits includes a slotted resilient canister capable of accommodating different size wires in a central bore, with the canister being filled with lubricant-retaining spronge-like material. The canister slot is adapted to receive a sponge-like and soap-filled insert which is placed in the longitudinal slot, with the slot providing access for the wires to the central bore. In one embodiment, all spong-like materials are packaged within apertured bags, thereby to prevent spillage while permitting the lubrication or soaping of wires or cables inserted into the central bore of the canister through the slot, with 360 degree lubrication being achieved through squeezing of the canister about the wire as it is pulled through the canister. One embodiment includes a rotatable canister cover or sleeve to lock the insertable piece to the resilient container. In a further embodiment, sponge-like material is provided in a bag which is impervious to the lubricant but has one or more apertures in one surface. With the sponge-like material fully-laden with lubricant, the bag is manually wrapped around the cable with the aperture facing inwardly, and lubricant is manually squeezed from the sponge-like material onto the surface of the cable as the cable is pushed through the wrap around bag.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
132 words
Apparatus for lubricating cables to be Pulled through a conduit, comprising: a canister having an outer body with ends, and a slot extending from an exterior surface of said canister and through a portion of each end to a longitudinal position within said canister, said ends having central openings to accommodate the passage of said cable through said canister; lubricant dispensing means lining said slot and adapted to dispense lubricant onto the portion of a cable in said slot as said cable is moved through said canister; removable insert means adapted to be placed in said slot after cables to be lubricated are placed in said slot; and means for sealing said canister with said insert in place, such that said canister with said lubricant dispensing means surrounds an inserted cable portion.
Claim 2
Dependent Claim
132 words
Apparatus for lubricating cables to be Pulled through a conduit, comprising: a canister having an outer body with ends, and a slot extending from an exterior surface of said canister and through a portion of each end to a longitudinal position within said canister, said ends having central openings to accommodate the passage of said cable through said canister; lubricant dispensing means lining said slot and adapted to dispense lubricant onto the portion of a cable in said slot as said cable is moved through said canister; removable insert means adapted to be placed in said slot after cables to be lubricated are placed in said slot; and means for sealing said canister with said insert in place, such that said canister with said lubricant dispensing means surrounds an inserted cable portion.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 wherein said longitudinal position corresponds to the center line of said canister.
Claim 4
Dependent Claim
21 words
The apparatus of claim 1 wherein said lubricant dispensing means dispenses lubrication carried therein upon squeezing of said lubricant dispensing means.
Claim 5
Dependent Claim
30 words
The apparatus of claim 3 wherein said canister is made of resilient material capable of being manually compressed, thereby to permit squeezing of said lubricant from said lubricant dispensing material.
Claim 6
Dependent Claim
32 words
The apparatus of claim 3 wherein said lubricant dispensing means includes sponge-like material and further including a lubricant impervious casing surrounding said sponge-like material, said casing having apertures along said longitudinal position.
Claim 7
Dependent Claim
33 words
The apparatus of claim 1 wherein said insert means contains said lubricant dispensing material and wherein said insert means extends only partway into said slot, thereby to define a bore through said canister.
Claim 8
Dependent Claim
20 words
The apparatus of claim 6 wherein said insert means further includes a lubricant impervious casing having apertures along said bore.
Claim 9
Dependent Claim
68 words
The apparatus of claim 2 wherein said canister includes concentrally located shell portions, with the inner shell portion adapted to rotate around the centerline of said canister, said inner shell portion adapted to rotate over said slot and insert and to clamp said insert into said canister while at the same time sealing any inserted cable into said slot for prohibiting leakage of said lubricant from said canister.
Claim 10
Dependent Claim
96 words
The apparatus of claim 8 wherein the outer shell portion includes partially completed circular end pieces, each having a central aperture, the inner and outer end pieces at each end of said canister being in contacting adjacency; and, wherein said inner shell portion includes centrally-apertured partially-circular end pieces, such that when said inner shell portion is rotated to its locking position, the respective end pieces being in contacting adjacency form a completed central aperture in the respective end of said canister, thereby to form a seal about an inserted cable at each end of said canister.
Claim 11
Independent Claim
117 words
A method for lubricating a cable to be pulled through a conduit with a soap type lubricant without spillage, comprising the steps of: providing a slotted soap-carrying canister having a sealable insert adapted to fit in said slot, said slot extending through the end portions of said canister, with said canister having apertured end pieces, at least a portion of which form a portion of said slot; inserting a portion of the cable in said slot; inserting and sealing said insert over said cable, with a portion of said cable extending from each end of said canister; and pushing said cable through said canister, thereby to apply soap-type lubricant to the cable portions emerging from said canister.
Claim 12
Independent Claim
117 words
A method for lubricating a cable to be pulled through a conduit with a soap type lubricant without spillage, comprising the steps of: providing a slotted soap-carrying canister having a sealable insert adapted to fit in said slot, said slot extending through the end portions of said canister, with said canister having apertured end pieces, at least a portion of which form a portion of said slot; inserting a portion of the cable in said slot; inserting and sealing said insert over said cable, with a portion of said cable extending from each end of said canister; and pushing said cable through said canister, thereby to apply soap-type lubricant to the cable portions emerging from said canister.
Claim 13
Dependent Claim
13 words
The method of claim 10 wherein said canister contains resilient sponge-like lubricant-bearing material.
Claim 14
Dependent Claim
32 words
The method of claim 11 wherein said canister is resilient and further including the step of squeezing said canister so as to express said lubricant onto the cables passing through said canister.
Claim 15
Independent Claim
77 words
A method for lubricating a cable to be pulled through a conduit with lubricant so as to facilitate passage of the cable through the conduit comprising the steps of at least partially surrounding a portion of the cable with a flexible resilient bag containing sponge-like material bearing lubricant said bag having lubricant dispensing apertures positioned to disperse lubricant onto the cable; and pushing the cable through said bag, whereby lubricant is applied to the cable without spillage.
Claim 16
Independent Claim
