4 Claims.

The present invention relates to newand useful improvements in machines for cleaning, painting or otherwise treating a cable or stay with a liquid coating and has for its primary object to provide a device of this character by means of which overhead stays, lines or cables leading aloft on shipboard or elsewhere may be cleaned, painted or otherwise treated with a liquid coating from the ground or deck of a ship whereby to eliminate the danger and the difficulties of elevating a workman in a bosns chair or similar lifting device.

A further object of invention is to provide a device of this character which may be hoisted on the cable or stay'to be treated and embodying' a fountain'br'ush surrounding the cable together with means for supplying. the brush with paint or other liquid under pressure to paint or coat the cable as the device is moved upwardly or downwardly thereon.

A still further object of invention is to provide a pump mechanism for supplying. the paint or other liquid under pressure to the brush and arranged for manual operation by a. workman at the bottom of the cable.

A still further object of invention is to provide a device of this character of simple and practical construction, which is efii'cient and reliable in operation, relatively inexpensive in manufacture, easy to mol'in-t-n-i position on the cable or stay to be painted or otherwise treated and which otherwise is Well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein Figure I is a side elevational view. Figure 2 is a vertical sectional view. Figure 3 is a top plan view with parts broken away and shown in section, and

Figure 4 is a transverse sectional View taken substantially on a line 4-4 of Figure 2.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a sleeve including inner and outer walls 6 and I, the inner wall being adapted to surround spaced relation therefrom. The walls 6 and I are connected at their upper and lower ends by top and bottom annular chambers 9 and I0 a cable or stay 8 in slightly likenumerals refer to like parts throughout, and in which:

which are open at their inner edges adjacent the cable 8. v

Gaskets are positioned in the upper and lower annular chambers, each gasket being composed of upper and lower soft rubber rings ll and [2 between which is positioned an intermediate ring of felt or other material I3, the inner edge of the ring l3 in the upper gasketprojecting inwardly beyond the inner edge of the rings H and I2 to lightly contact the surface of the cable 8.

Positioned in the arm lar chambers behind the gaskets are annular leaf springs 14 to yieldably urge the ring l3 of the upper gasket into wiping contact with the cable rings ll, l2, [3 in the lower gasket. V

7 At one side of the sleeve 5 is a door [5 hinged along one vertical edge as shown at l6 forswing': ing into and out of open position as shown by the dotted lines in Figure 3' of the drawings to enable mounting of the sleeve on the cable 8. The door I5 is secured in a wing nut ll threaded on a screw 18 projecting from the sleeve and adapted for clamping against the lug l9 projecting from the free edge of the door.

The door I5 includes segments '29 and 2i on the upper and lower annular chambers Q and III for opening and closing movement together with the door to enable the positioning of the cable therein and the upper and lower 'gasketsare split transversely as indicated at 22 to likewise enable the gasket to be placed in position while the inner wall 6 is longitudinally split for the same pur p r At the inside of the door I5 and at'diametri cally opposite sides of the sleeve 5 are concave rollers 23 including trunnions 24 at the end thereof slidably mounted in slots 25 on inwardly-projecting supporting arms or brackets 26. Also freely mounted on the trunnions are Yokes 2 to which the inner ends of adjusting screws 28 are rotatably connected and projecting outwardly through the sleeve for threaded adjustment therein whereby to adjust the rollers 23 relative to each other for engaging diametrically opposite sides of cables of various diameters.

A pair of

tanks

29 and 30 are connected to or formed at diametrically opposite sides of the sleeve 5 adapted to contain paint or other liquid to be applied to the cable 8, the top of each tank being provided with a filler cap 3| threaded thereon and in which is slidably mounted the stem 32 of a follower 33 engaged by a coil spring 34 for urging the follower downwardly in the tanks.

and to similarly urge the its closed position-by The bottom of each tank is provided with a discharge port 35 registering with a port 36 in a hollow pistOn 37 working in a cylinder 38 projecting laterally from the lower end of the sleeve 5.

A coil spring 39 is positioned in the cylinder 38 with its outer end projecting into the piston 31 to urge the piston outwardly. A roller it is journaled in the outer end of the piston bearing against a lever til which extends upwardly and is pivoted at its upper end to the adjacent tank as shown at 42. A stop pin 43 is carried at the outer end of the cylinder 38 and is positioned transversely of the lever 4! to limit outward movement thereof.

A pipe 14 is connected at its lower end to the inner end of the cylinder 38 and is provided with a check valve 65 therein, the pipe extending upwardly in the sleeve 5 between the inner and outer walls thereof and has its upper end projecting through the inner wall 6 for communication with a transversely split annular brush 46 secured to the inside of the sleeve at the disv charge end of the pipes M.

Links 47, which in the present disclosure embodies rope sections, connect the lower end of the levers H of the respective pumps to each other and connected to the rope 5! and extending downward therefrom is a rope 8 for operation by a workman at the bottom of the cable 8.

A bale i9 is attached to the upper portion of the

tanks

29 and 30 and to which a hoisting cable 56 is attached.

In the operation of the device the door i5 is opened so as to permit the sleeve 5 to be mounted on the cable, stay or other slender object to be painted or coated with the liquid, the door then being closed and the'rollers 23 adjusted by the screws 28 in accordance with the size of the cable.

As the device is hoisted by the rope 53 along the cable 8 the rope 48 is pulled downwardly to actuate the piston 3'! and pump the liquid from the tanks 29 and 3B upwardly through the pipes 40 for supplying the liquid to the brush it whereby to apply the liquid to the surface of the cable. The pistons 31 are moved to their original position as shown in Figure 2 of the drawings in their return stroke by releasing the rope s and the pumps may be actuated as frequently as desired to properly supply the paint or other liquid to the brush,

The ring 83 of the upper gasket and the rings Ii, l2, E3 of the lower gasket clean the surface of the cable as the painting thereof progresses and also prevent excess paint from dripping below the device,

It will be apparent from the foregoing that the device may be used for either painting the cable 8 or apply any desired liquid to the cable for treating or preserving the same.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
