Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to lubricating and cleaning apparatus. In particular, this invention relates to an apparatus for supplying a lubricant cleaner to a wire cable so as to lubricate and clean the wire cable.

2. Description of the Prior Art

In many usages, multi-strand cable, also termed wire rope, becomes quite fouled by dirt, old grease, grime, and the like. The nature of the usage renders it impractical, or at least inconvenient, to remove the cable for cleaning and relubricating. Typical examples include bridge suspension cables, elevator suspension cables, well operating suspension cables, and heavy duty crane cables. Furthermore, where such multi-strand cable is exposed to weather or to water, it suffers deterioration from rust and corrosion unless protected by some suitable material such as, for example, oil or grease.

Numerous lubricating and cleaning devices have been utilized for cable cleaning and/or lubricating. Such devices of the prior art generally utilize a pumping apparatus to apply a lubricant cleaner to the wire cable, and either a brush assembly or a die to remove the excess lubricant from the wire cable and clean the cable. However, such devices of the prior art, while satisfactory for their intended purpose, ordinarily leave something to be desired in that they are complex in design, costly, cumbersome to use, and somewhat inefficient.

SUMMARY OF THE INVENTION

The subject invention overcomes some of the disadvantages of the prior art, including those mentioned above, in that it comprises a relatively simple wire rope lubricator cleaner which may be utilized to lubricate and clean a multi-strand wire cable passing therethrough.

The subject invention includes a rectangular shaped frame having a lubricating canister removably coupled thereto at one end thereof. At the opposite end of the rectangular shaped frame is an upper slide assembly which rotatably supports a die. The wire cable passes through the lubricating canister which applies a lubricant cleaner, and then to the die. The die, which has a plurality of internal spiral grooves adapted to fit the spiral strands of the wire cable, then cleans the wire cable and removes from the wire cable the excess lubricant cleaner applied thereto.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The preferred embodiment of the subject invention will now be discussed in some detail in conjuntion with all of the figures of the drawing, wherein like parts are designated by like reference numerals, insofar as it is possible and practical to do so.

Referring now to FIG. 1, there is shown a wire rope lubricator cleaner 11 comprising a rectangular shaped frame 13. Rectangular shaped frame 13 includes an upper rack handle assembly 15 fixedly attached to a pair of bracing bars 17 and 19. Fixedly attached to the opposite end of bracing bars 17 and 19 is a lower rack handle assembly 20 having a pair of mating members 21 and 22.

Rigidity of rectangular shaped frame 13 is provided by triangular support elements 23, 25, 27, and 29. Triangular support element 23 is positioned between upper rack handle assembly 15 and bracing bar 17, triangular support element 25 is positioned between upper rack handle assembly 15 and bracing bar 19, triangular support element 27 is positioned between lower rack handle assembly 20 and bracing bar 17, and triangular support element 29 is positioned between lower rack handle assembly 20 and bracing bar 19. Of course, triangular support elements 23, 25, 27, and 29 may be attached to rectangular frame assembly 13 by any suitable conventional means, for example by welds.

Affixed to bracing bars 17 and 19 of rectangular shaped frame 13 is a lower slide assembly 31. Lower slide assembly 31 includes a support bar 33 fixedly attached at one end thereof to bracing bar 17. A bumper element 35 is fixedly connected to the opposite end of support bar 33. A support bar 37 is fixedly attached at one end thereof to bracing bar 19. A bumper element 39 is fixedly connected to the opposite end of support bar 37.

A support block 41 having a mating member 43 and an aperture 45 extending therethrough is mounted around support bar 33 such that support block 41 is in slidable engagement with support bar 33. A spring 47 slidably mounted around support bar 33 between bracing bar 17 and support block 41 exerts a force upon support block 41 so as to push support block 41 against bumper element 35. A support rod 49 is attached at one end thereof to support block 41. Fixedly connected to the opposite end of support rod 49 is a tip element 51.

A support block 53 having a mating member 55 and an aperture 57 extending therethrough is mounted around support bar 37. A spring 59 slidably mounted around support bar 37 between bracing bar 19 and support block 53 exerts a force upon support block 53 so as to push support block 53 against bumper element 39. A support rod 61 is attached at one end thereof to support block 53. Fixedly connected to the opposite end of support rod 61 is a tip element 63.

A lubricating canister 65 having a strap hinge 67, an intake port 69, and an aperture 71 extending therethrough along a predetermined line 73 is removably coupled to rectangular shaped frame 13 so as to allow lubricating canister 65 to be removed therefrom. Mounted upon one end of lubricating canister 65 is a first pair of support members 75 and 77, each of which has a slot, not shown, therein. Mounted upon the opposite end of lubricating canister 65 is a second pair of support members 79 and 81, each of which has a slot, not shown, therein.

Mating members 21, 22, 43, and 55 are respectively in slidable engagement with the slots of support members 75, 77, 79, and 81 such that by moving support block 41 in the direction of bracing bar 17 and support block 53 in the direction of bracing bar 19, lubricating canister 65 may be removed from rectangular shaped frame 13.

An upper slide assembly 83 is mounted around upper rack handle assembly 15 in slidable engagement therewith. Upper slide assembly 83 includes a die support block 85 having a boss 87 fixedly connected to one side thereof and a sleeve 89 fixedly connected to the opposite side thereof. Mounted upon a third side of support block 85 is a toggle latch 91. Oppositely disposed from toggle latch 91, on a fourth side of die support block 85, is a toggle latch 93, FIG. 3. Upper slide assembly 83 has an aperture 95 extending clear through along predetermined line 73. Mounted through an aperture 97, which extends clear through die support block 85, is rack handle assembly 15. Toggle latches 91 and 93 when released allow upper slide assembly 83 to be separated along predetermined line 73 and slide upon upper rack handle assembly 15, as will be discussed more fully below.

Rotatably supported by boss 87 of upper slide assembly 83 is a die 99 having an aperture 101 extending therethrough and a flange 103. At this time it may be noteworthy to mention that die 99 is separable into die halves 105 and 107.

Referring now to FIGS. 1 and 4, there is shown flange 103 of die 99 having a pair of bolt holes 109 and 111 extending therethrough. A pair of bolts 113 inserted within bolt holes 109 and 111 of flange 103 and a pair of nuts 115 are utilized to fasten together die halves 105 and 107 around a wire cable 117 so as to form die 99.

Wire cable 117, which has a plurality of spiral stands 119, is passed through aperture 71 of lubricating canister 65, aperture 101 of die 99, and aperture 95 of upper slide assembly 83 along predetermined line 73.

Located within die 99 are a plurality of internal spiral grooves 121 fitting spiral strands 119 of wire cable 117 such that as wire cable 117 passes through die 99 from lower rack handle assembly 20 to upper rack handle assembly 15, die 99 will be rotated about boss 87 of upper slide assembly 83.

At this time it may be noted that whenever wire cable 117 is passed through die 99 in a direction opposite that discussed above, tip elements 51 and 63 of lower slide assembly 31 provide support for die 99.

Also, it may be noteworthy to mention that die 99 is a brass casting. Brass was utilized for die 99 because brass has excellent bearing characteristics, thereby allowing spiral strands 119 of wire cable 117 to pass freely through die 99.

Referring now to FIGS. 1 and 2 and 5, there is shown a supply tank 123 having an output port 125. Output port 125 of supply tank 123 is connected to an intake port 127 of a pump 129 by a supply line 131. An output port 133 of pump 129 is connected to intake port 69 of lubricating canister 65 by a supply line 135. Supply tank 123 and pump 129 provide lubrication canister 65 with a lubricant cleaner, not shown, to be applied to wire cable 117 as wire cable 117 passes through lubrication canister 65, the details of which will be discussed more fully below.

Mounted upon the outer surface of lubricating canister 65 in diametrically opposed alignment from strap hinge 67 are a pair of toggle latches 139 and 149. Upon removing lubricating canister 65 from rectangular shaped frame 13 and then releasing toggle latches 139 and 141, lubricating canister 65 may be opened about strap hinge 67.

It may be noteworthy to mention at this time that lower rack handle assembly 20 has therein a centrally located U-shaped member 137 which allows wire cable 117 to pass through lower rack handle assembly 20.

Referring now to FIGS. 1 and 3, there is shown rectangular shaped frame 13 having lubricating canister 65 and die 99 removed therefrom. A pair of circular bumper elements 143 and 145, mounted upon upper rack handle assembly 15 of rectangular shaped frame 13, are utilized to prevent upper slide assembly 83 from shifting positions along upper rack handle assembly 15 when wire cable 117 passes through upper slide assembly 83.

It may be noteworthy to mention that upon releasing toggle latches 91 and 93, upper slide assembly 83 is separable about predetermined line 73, as shown in FIG. 3.

The operation of the invention will now be discussed briefly in conjunction with all of the figures of the drawings.

Referring now to FIGS. 1, 2, and 4, there is shown wire cable 117 passing through U-shaped member 137. Supply tank 123, which has stored therein the lubricant cleaner to be utilized in lubricating and cleaning wire cable 117, supplies to pump 129 the aforementioned lubricant cleaner. Pump 129, in turn, delivers to lubrication canister 65 under pressure the lubricant cleaner which is then applied by lubrication canister 65 to wire cable 117 as wire cable 117 passes therethrough.

The lubricant cleaner when applied to wire cable 117 acts as a solvent so as to dissolve any hardened residue which is present on wire cable 117, and as a lubricant so as to lubricate wire cable 117.

The lubricant cleaner applied by lubrication canister 65 to wire cable 117 may be any conventional, well known, and commercially available lubricant cleaner. In particular, it has been found that a lubricant cleaner designated Molub-alloy, manufactured by Imperial Oil and Grease, Inc., of Los Angeles, Calif., performs quite satisfactorily as the lubricant cleaner.

Wire cable 117 then passes through die 99 which removes from wire cable 117 the excess lubricant cleaner including the dissolved residue. As wire cable 117 passes through die 99, spiral strands 119 of wire cable 117, which fit internal spiral grooves 121 of die 99, rotate die 99 about boss 87 of upper slide assembly 83. The close fitting of wire cable 117 within die 99 allows for the retention on the surface of wire cable 117 of no more than the desired amount of lubricant.

At this time it may be noteworthy to mention that wire rope lubricator cleaner 11 may be employed to clean and lubricate wire cables, not shown, of various diameters. A plurality of dies, not shown, each of which has internal spiral grooves fitting the spiral strands of one of the aforementioned wire cables may be utilized within wire rope lubricator cleaner 11.

From the foregoing, it may readily be seen that the subject invention comprises a new, unique, and exceedingly useful wire rope lubricator which constitutes a considerable improvement over the known prior art. Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced other than as specifically described.
