16 Claims.

The present invention relates to a scaling machine for cleaning the sides of a ship and the like.

An important object of the invention is to provide a simple, efficient, compact scaling machine arranged to be connected to the side of a ship so as to be movable longitudinally and vertically over-the surface to be treated, and which is provided with means for thoroughly and effectively removing scale, paint, rust and barnacles so as to obtain a clean, unstreaked scale surface at a minimum expenditure of time and cost.

'A further object comprehends the provision of a portable sealer attachment including a guide frame suspended from the side of a ship and with which is associated a vertically movable carrier that is guided by the frame. Driving means mounted on the carrier is operatively connected to the suspension frame to impart vertical movement to the carrier relative to the frame. Extending outwardly from the carrier andpreferably on opposite sides of the driving means are batteries of sealers or cleaning tools arranged in transverse rows and provided with scaling tools or guns that engage the side of the ship and are movable over a wide vertical and longitudinal area in a continuous operation.

A further object is to provide a suspension frame movably connected to the outer side of a ship to be cleaned, and which supports a movable sealer having tools arranged to be moved into engagement with the side of the ship during the cleaning operation. The sealer is provided with a platform movable therewith and on which a workman stands to control the operation of the scaler tools. Additionally, the frame has a fixed auxiliary platform at the lower end thereof for a second workman and which is provided with manually operable means connected to the sides of the ship to maintain the frame and carrier in a fixed position. The auxiliary frame also carries means connected to the ship and operable for moving the suspension frame and carrier longitudinally relative to the ship. The second workman stands on the auxiliary platform and controls the movement of the suspension frame and its associated parts relative to the ship.

Another object consists in forming the movable carrier with a vertically disposed base plate having outwardly spaced therefrom vertically disposed spaced rows of slat members, each of which rows includes a pair of inner and outer overlapping plates. To the outer plates are connected transverse rows of sealers arranged to be moved into operative engagement with the side of the ship during the clean operation. The outer plate is wider than the inner plate and associated with the ends of the inner and outer plates are means for adjusting the outer plate laterally relative to the inner plate, so that the rows of sealers may be longitudinally adjusted when operating conditions require slight lateral movement of the sealers relative to the work. Additionally, yieldable means are provided for moving and maintaining the inner and outer plates and the sealers in engagement with the work.

Other objects and advantages of the invention will become apparent from the following description when taken in conjunction with the accompanying claims and drawings.

Referring to the drawings in which is shown a preferred embodiment of the invention:

Figure 11 is an enlarged detail sectional view showing the yieldable means connected to the carrier for urging the sealer in engagement with the shell of the ship, and

Figure 12 is a sectional view taken substantially along the line l2--l2 of Figure 10.

Referring to the drawings in which like numerals indicate like parts in the several figures,

l5 (Fig. l) designates the side shell of a ship to which the upper deck l6 may "be connected at the gunwale I! by a weld l8 (Fig. 4). A fixed support I!) is secured to the gunwale ll and may be coextensive in length therewith. A guide rail 20 is welded or otherwise connected to the outer side of the support l8 and has a V-shaped1ongitudinal groove 2| that receives similar shaped spaced wheels or rollers 22, each of which rollers is journalled at 23 to a laterally extending arm or strap 24 welded or otherwise connected as at 25 to one of a pair of spaced vertically disposed guide channel members 26. The channel members 25 are connected together by vertically spaced U-shaped bars 1 2? (Fig. 3) that have parallel arms 23 extending outwardly from the channel members and are connected together by a transverse rail portion 29. The adjacent vertically spaced side arms 28 may be connected by cross braces 3%, and a vertical ladder may be secured to the transverse portions 29 of the U-shaped members so as togextend from ;the top to the bottom of the channel members 26.

The channel members 25, together with the bars 21 and braces 30, constitute a suspensio or guide frame that is movable by the rollers.22

along the guide track 2 i, and associated with the suspension frame is a vertically movable carrier generally indicated by the numeral 32 (Fig. 6).

.Theearrier 32 preferably comprises an elongated Vertically disposed base plate 33 positioned between the channel members 28 and having parallel side bearing members 3 t welded as at 35 to the opposite sides thereof (Fig '7) adjacent its .upper and lower ends, and to which are connected the outwardly extending axles or shafts 36 that carry the rollers. 3'? which extend into the :channelrmembers 26 between the arms thereof so as toguide and control the vertical movement of the carrier 32 relative the suspension frame and the shell IS. The outer face of each .of the channel members 26 may be provided with spaced elongated openings. 33 to reduce their weight.

A transverse drive shaft 39 (Fig. 8) is positioned in front ofthe base plate 33 and is,connected thereto .by the spaced bearing members 48 and the boltsii. .Areversing motor or the like. is connected to the'rear of the plate 3-3 by the spaced braekets ill and is operatively connected through a transverse shaft M to a gear reducing mechanism tifisecured to the rear of the'plate33 by thespaced brackets it. 'A- shaft 47 'extends outwardly and forwardly from the reducing gear mechanism and has keyed thereona bevel pinion fi8 as at-49. The pinion 48 meshes with agear' fifi-keyed as-at 51 to the transverse drive shaft 39. The ends of the shaft 39 arereduced as at=-52 and terminate in thread ed portions 53. Keyed or otherwise non-rotatably secured to the reduced portions 52 are pinions 54 which-mesh with rack bars-tethat are secured to the outer arms-56 of 'thechannel members 25 by welding or the like as at The rack bars are substantially coextensive in length with the channel members 26, and it will be seen that rotation of the shaft 39 through the mctor li. and reducing gear mechanism 45 will cause vertical movement of the carrier 32 and its assoeiatedparts relative to the channel members 26.

and an overlapping laterally displaceable front plate 53 of the same width as the back plate but of slightly longer length, as best shown in Figures 7 and 9. To the rear of each of the back plates 62 are connected outwardly spaced tubular members 8:3 as at 65 (Fig. 7), each of which telescopically receives a cylinder that extends through an opening E3? in the wall of the base plate 33 (Fig. 11) and is welded thereto as at 58. To the inner end of the tubular member 64 is connected an annular stop member or ring 69 through which extends a threaded bolt or plunger E8 having its head ll normally abutting the lower side of the stop member 6.9. Surrounding the bolt-l9 and confined between the stop v(Stand anadjusting nut 7 l on the threaded portion 72 of the bolt, is a coil spring '13 which tends yieldably to urgethe inner and

outer plates

62 and 63 outwardly away from the base plate 33. A closure cap 74 is threaded as at 1'5 to the sleeve -66 and has a central opening-through which the plunger ll! extends and the outer endof the plunger may be of polygonal shape as at 16 to ,receive a suitable tool for controlling or adjusting the tension of the spring ":3. A locking nut ll may be connected to the threaded portion 72 for retaining the nut T! in a fixed position. To each of the front plates 63 is connected a transverse. row or battery of scale removers or cleanersl'l8. of any conventional type, such as Oldham sealers. Each sealer-"l8 may include an elongated outer casing 19 welded at 89 to its associated front plate 63 (Fig. 12) v and an inner casing or housing 8| within the outer casing 79 and extending outwardly therefrom and of substantially the same configuration. Reciproeally mounted within the inner casing. 8i are preferably three spaced sealer tools or guns 82, each .of which tools has an enlarged inner end porouter surface of the plate 33, so as to provide Positioned in front of plate 33 and spaced therefrom ,arevertically spaced transverse rows of flat slat'members or straps 58, 59, 68 and SI (Fig. 6), preferably having the

slat members

58 and 59 positioned above the drive shaft 39 and the slat members 60 and SI below the same. Manifestly, the number and arrangement of the slat members may be varied'as operating conditions require. Each horizontal row of slats .58, 59, 6D and 6| comprises a bacl; plate52 (Fig.7)

shock absorbing means during the operation of the sealers 78. Each of the clamps 8 5. is also formed with spaced side openings through which the threaded studs 81 extend, and these studs are-welded or otherwise connected at their lower ends-as at 88 to the outer wall of the casing 2 9 so as to maintain the inner easing 8| and its associated parts firmly within the outer casing '59. The clamps 84 for the end sealers (Fig. 10)

i a have their outer ends enlarged as at 85 and are connected by spaced pairs or studs 8? to the easings in the same manner as the intermediate sealers.

The'sealer tools 82 are operable by any suitable fiuid;such'as compressed air, which is conducted from a main supply line 39 (Fig. 9) through a flexible connection, such as a rubber hose orthe like Ell], to an inlet pipe 9! of the manifold 92 that is provided with longitudinally spaeedoutlet pipes 93 connected by the flexible conduits 94 to chambers 8| (Fig. 12) in each of the casings SI of the sealers, so as to impart reciprocating movement to the tools 82 when the machineis in operation. .The top 85 of the inner casing 8! (Fig. is provided with spaced longitudinally disposed rows of outlet openings 82' through which the fluid may discharge from the chamber 8! during the operation of the reciprocating tools 82. Preferably, the transverse rows of scalers are inclined alternately in opposite directions with respect to each other (Fig. 6), and the end scalers it of each row have the conduits 9 delivering to the side thereof while the intermediate sealers have the conduits communicating with their ends (Fig. 10). A manually operable valve 80' may be provided for controlling the flow of the pressure fluid through the supply line 90.

To the upper end of the carriage 32 (Fig. 6) are connected spaced cables 95 as at 35. Each of the cables 95 extends upwardly and over a pair of sheaves 971 (Fig. 2) connected to the upper end of each channel member 26, and then downwardly along the side thereof, and is connected at its lower end to a weight 98 so as to provide eounterbalancing means for maintaining the carrier 3-2 and its associated parts in a relatively fixed position during the scaling operation. Extending outwardly from the lower end of the carrier 32 so as to be movable therewith, is a platform 99 on which the operator of the sealer stands to raise or lower the carrier during the scaling operation. A protective rail 98' may be connected to the carrier above the platform. The lower end of the suspension frame is provided with an auxiliary fixed platform lei? (Fig. 3) connected to the sides of the channel members 2% by vertically spaced U-shaped bars it! and 532 that extend outwardly beyond the bars 2?, and which may be connected by the vertical arms or strips I03 (Fig. 1). Extending downwardly from the bar Hi! are spaced inclined arms it that are connected to the channel members 25 by horizontal arms 5%. To the inner sides of the arms of the upper U-shaped bar 4172 are journalled hand Winches or drums Hi5 (Fig. 3), on each of which is wound one end of a cable I01 that extends downwardly past a guide pulley [58 (Fig. l) and then inwardly as at I99 so as to be connected at its opposite end to a pad eye II!) that may be welded as at H! to the side shell of the vessel at a spaced distance from the carrier 32, in order to provide means for maintaining the scraper attachment in a fixed position adjacent the side of the ship during the scaling operation. The upper U-shaped arm H32 of the auxiliary platform may also be provided with spaced hand winches M2 to each of which is connected one end of a cable H3 so as to be wound thereon. The cable H3 extends inwardly and passes up under a sheave H (Fig. 4) and over a sheave l 55 journalled in the upper end of an adjacent channel member 26, and then extends longitudinally of the gunwale I? (Fig. 2) so as to be connected to a stanchion or a fixed member H5 as at ill. The stanchions ii are laterally spaced from the carrier 32 so that upon operation of the winches M2, the suspension frame and the carrier 32 may be moved longitudinally along the side of the ship.

Each of the spaced stanchions or posts H6 may be connected to the deck it in any suitable manner as at H8 (Fig. 2). Spaced guide wheels H9 extend outwardly from the carrier 32 so as to engage the shell 55 in order to maintain the scalers in proper operative position and facilitate the vertical movement of the carrier. Each of the rollers H9 is journalled in a yoke I20 6 (Fig. 7) having a threaded shank 12! that extends through a transverse elongated slot E22 in the front plate 53 (Fig. 11) of the slot members, and a circular opening H3 in the rear plate 62. A nut I24 on the shank [2i bears against the plate ,63 adjacent the slot I22, and a nut {25 on the shank l2] engages the plate 62 so as not only to secure the wheels H9 to the carrier but alsoelamp the front plate 63 to the rear plate 62 and allow the front plate to be moved laterally relative to the rear plate when slight adjustment of the sealer tools is desired. Each of the outer plates 63 is laterally adjustable relative to its inner plate 62 within predetermined limits, by set screws I26 that extend through members I21 that abut the ends of the front plate 63 (Fig. 7) and are spaced from the ends of the rear plate 62 so that the inner ends of the screws engage the adjacent sides of the plate 62 in order that upon rotation of the screws, the plates 53 and the scalers l8 may be adjusted laterally during the operation of the device, when such adjustment is required due to obstructions or protuberances on the outer side of the shell 15.

Preferably, two men operate the sealer. One operator stands on the platform 99 to controlthe operation of the scaling tools or guns Si and the vertical movement of the carrier 32 relative to the guide members or suspension frame, so as to advance the tools over the surface being treated. The other operator will stand on the platform its so that by rotating the winches we to maintain the cables I59 taut to insure the sealer being firmly held in proper operative position during the cleaning operation. When it is desired to move the machine longitudinally after a vertical surface of the ship has been cleaned, the operator on the platform 5 cc loosens the cables Hi9 by operation of the winches I36, and then rotates the winches H2 in the desired direction so that the suspension frame and the carrier 32 may be moved as a unit to position the sealer tools 8! adjacent the area to be cleaned. Thus, it will be seen that if the left-hand winch in Figure 2 is rotated so as to tighten its associated cable H3 and the right-hand winch H2 is actuated to slacken its adjacent cable l i3, that the pressure developed will cause the suspension frame and carriage to be moved bodily toward the left, assuming, of course, that the winches I97 have been previously actuated to slacken the cables N39. The platforms 99 and H10 are conveniently accessible by the ladder 3i. The scaling device may efiiciently and expeditiously be operated by two men, one on the platform 99 for controlling the operation of the sealer tools and the vertical movement of the carriage, and the other workman who stands on the platform I00 so as to operate the pairs of winches in order that the machine may be maintained in proper operative position relative to the side of the ship and for moving the suspension frame longitudinally during the scaling operation. The outward pressure exerted by the springs iii within the cylinders 66 against the inner plate 62 provides means for yieldably maintaining the tools 8| in proper operative position during the scaling operation. The vertically spaced rows of sealing tools are staggered relative to each other in a vertical plane to insure the entire area over which the machine passes being thoroughly scaled during its operation.

Thus, it will be seen that a simple, efficient gangs-4s be easily and conveniently moved across theisurface vto-be treatedand issoarranged as to cover a .wide cleaningwarea in .a: continuous operation and at a minimum expenditure of timeand-labor. The scaler device is intended toclean the vertical portion or straight-away surface of. the shell, and the curved portions of the bow andisternaare cleaned by hand.
