Application filed October 12, 1895. Serial No. 565,502. (No model.)

which may be readily carried on shipboard and easily brought into use when required, and adapted to be used either while the ship is afloat or in dry-dock.

The main object of the present invention is to provide such an apparatus with a iiexible frame, whereby the same may accommodate itself perfectly to the bilge and curvature of the ships hull beneath the load water-line.

A further object of the invention is to provide in connection with such frame a series of cleaning-brushes mounted upon endless guide-pins and capable of traveling transversely beneath the hulll from the load waterline to the keel, or vice versa.

The invention also has for its object to provide a novel gripping device attached to the cleaning-frame and adapted to be operated from above the surface of the water, so as to grip the keel as in a vise, thus securing the lower end of the cleaning-frame rigidly to said keel.

Other objects and advantages of the invention will appear in the course of the subjoined description.

The invention consists in an improved apparatus for cleaning ships bottoms, embodying certain novel features and details of construction and arrangement of parts, whereby increased efficiency is attained, as hereinafter fully described, illustrated in the drawings, and finally embodied in the claims.

In the accompanying drawings, Figure l is a perspective view of the improved apparatus constructed in accordance with the present invention. Fig. 2 is a cross-sectional view of a ships hull, showing the application of the improved apparatus. Fig. 3 is an enlarged detail perspective view of the keel-gripping feature. Fig. 4 is an enlarged detailsectional view through a portion of the chain of brushes. Fig. 5 is a detail perspective view of one of the adjustable roller-frames by means of which the apparatus may be adjusted fore and aft. Fig. 6 is a detail view of one of the brushes.

Similar numerals of reference designate corresponding parts in the several figures of the drawings.

For the purpose of carrying out the present invention I employ two flexible and elastic frames, (designated by the numeral l.) Each of said frames comprises a pair of elastic bars 2, which are arranged in parallelism .and spaced in a full-sized machine in the neighborhood of three feet apart, varying, of course, according to the size of the boat upon which the device is to operate. These'side bars are connected at their extremities by transverse tie-bolts 3, which pass through terminal eyes in the said side bars and have disposed around them sleeves or spacingtubes 4, which hold the side bars a sufficient distance apart. Two open rectangular frames are thus obtained, and these frames are connected at their lower ends bya series of links 5, which pass around the extended ends of the adjacent tie-bolts 3 and also around two or more transverse bolts 6, similar and arranged in parallelism to the tie-bolts 3 and also provided with spacing-sleeves 7. ll-ly'ljhe last-named bolts (l are interposed at regular i intervals between the bolts 3 of the frames l, and each of said bolts is connected with the bolt next adjacent to it by means of independent links arranged one at each end. The frames and the bolts 3 and 6 while thus firmly interconnected are capable of yielding independently, so that they will accommodate themselves to and dispose themselves beneath and upon the sides of the ships keel in the manner illustrated in Fig. 2. Vhen adjusted into the position just described, the bolts referred to may be caused to firmly grip the keel of the vessel by means of a series of lever-arms 8, four of such lever-arms being shown, two upon each side of the device. Each of said lever-arms is formed with two eyes or bearings 9, which embrace the projecting extremity of one of the end bolts 3 of the adjacent frame l, and the other the correspending end of the intermediate bolt 6, n ext IOO adjacent thereto. All of the lever-handles are disposed in the same manner and at their outer ends attached to ropes or chains 10, which extend in opposite directions beneath the hull of the boat and upward above the surface of the water, where they may be hauled taut by the deck-hands and made fast to the rails. The apparatus may thus be temporarily clamped to the hull of the boat and caused to grip the keel as in a vise, so that it will be impossible for the apparatus to slip or move longitudinally of the keel in either direction.

11 designates a plurality of outwardly-projecting blocks, which are secured to the elastic side bars of both frames by means 0f U- shaped straps l2, of metal, the said straps passing around and embracing the said framebars and also embracing the blocks 11 upon opposite sides thereof and being riveted or otherwise secured thereto, as shown. These straps 12 hold the blocks 11 firmly in place upon the elastic bars of the frame and at right angles thereto and form the bearings for a series of transverse rods or bolts 13, surrounded by antifriction-sleeves 14, constituting rollers against which the clcanin g-bru shes have their bearing. Journaled on the end bolts or rods 13 of each frame are enlarged rollers or drums ,15, and upon the opposite ends of the upper roller or drum are secured sprocket-wheels 16. Sprocket-chains 17 pass over these sprocket-wheels and extend downwardly to the lower end of the frame, where they pass over the lower roller or drum, the said chains being guided at intermediate points by means of the antifriction sleeves or rollers 14 and short supplemental rollers 18, revolubly mounted upon the inner faces of the blocks l1 and upon the opposite sides of the chains from the sleeves or rollers 14. The chains are thus caused to travel between antifriction guiding-rollers and are thus held properly to their work. The pivots 19 of certain KVlinks of the chain, at equal intervals d'a'part, are extended transversely across from one chain to the other. These extended pivots are arranged in pairs and are received in facial grooves 20 in the back 21 of a cleaning or scouring brush 22. Any number of said brushes may be employed and the operative faces of said brushes are preferably made to exceed in area a half-cylinder, so that said brushes may swing freely to accommodate themselves to any unevenness in the ships bottom and yet present their operative faces thereto. Metal bristles or bass or any other suitable material may be used in the manufacture of the brushes 22. Arranged between the chains and secured to the backs of the brushes is an endless belt of rubber, as indicated at 23. This belt also passes around the end drums or rollers and serves to hold the brushes upon the extended pivots of the chains and also assists in preserving the proper poise of the several brushes and restore the same to their proper working positions.

'lhe shaft of the upper roller or drum is extended beyond the blocks 11, in which it has its bearings, and is provided outside of said blocks with spur-gears 241, which mesh with corresponding gear-wheels on a countershaft 25, arranged above and in parallelism to the drum-shaft. This last-named shaft 25 is provided with a drum or pulley 26, from which a belt may be extended to an engine of any description arranged upon the deck of the vessel or other convenient point. In this manner motion may beimparted to the chain of brushes for causing them to traverse the ships bottom and clean any barnacles orother foul matter therefrom. The opposite ends of the upper-drum shaft are also extended beyond the spur-gears sufficiently to receive oppositely-disposed cranks 27, which are preferably made of a size which will admit of the employment of two men for each crank. Provision is thus made for operating the brushes by hand-power as well as from a driven belt.

28 represents a rope or cable which attaches to a link 29 at the bottom of the frame 1, and extends thence upwardly outside of pulleys 30, journaled upon the outer faces of the blocks 11, and attaches to the rail of the vessel. By means of this arrangement and with the aid of four of such ropes or cables arranged upon the opposite sides of both of the 'elastic frames 1 the latter may be drawn inward against the submerged hull of the vessel, so as to fit snugly against the same and accommodate themselves accurately and perfectly to the outline and curvature of such hull.

31 designates a pair of pivoted frames which are mounted between laterally-proj ecting ears extending in opposite directions from an opposite pair of blocks 11, preferably at a point central of the vertical extent or length of each of the elastic frames. Each of said frames 31 is provided at one cnd with an eye, and thc opposite end thereof is forked to embrace a bearing-roller 33, which is journaled therein. These rollerframes are so arranged that they may be connected with ropes or cables 34, running fore and aft and attached to the eyes 32. By drawing upon these ropes or cables the roller-frames may be vibrated upon their pivots in such manner as to project the roll ers inside of the inner faces of the elastic frames l, thereby permitting the apparatus to be moved toward the bow or stern of the vessel, as required. When these ropes are secured at their opposite ends, they serve as additional stays for holding the apparatus in place.

In operation the apparatus is lowered from the bow of the vessel, whereupon the weight of the apparatus will carry it to a sufficient depth, so that it may be moved longitudinally and passed underneath the vessel to the desired point. The upper ends of the elastic IOO IIO

frames are now made fast by means of suitable stay-ropes which attach to the frames and to the rail of the vessel. The ropes which connect with the keel-grip levers are now hauled taut, thereby causing the apparatus to lirmly grip the keel, as hereinabove stated.

. After making these ropes fast the ropes 28 are drawn taut and made fast to the rail of the vessel, thus causing the elastic frames to assume a curvature corresponding to the lines of the hull. By now setting the train of brushes in motion the barnacles and other foul or foreign matter which may have accumulated on the hull are removed from the path in which the brushes travel. The apparatus may be read justed in a similar manner to a different point and the operation repeated until the entire hull of the vessel below the water-line shall have been cleaned. Another valuable function of the elastic frames of the apparatus resides in the adaptability of the same for assisting in the stoppage of a leak in the vessels hull. Should a hole be stove in the vessels hull beneath the water-line, one or more thicknesses of canvas or other suitable material may be attached to the elastic bars of one of the frames v l, and thus be lowered beneath the surface and brought into position to cover such hole or leak. Owing to the flexibility and elasticity of such frame the canvas will be pressed firmly against the bottom of the vessel and securely held against escape. The action of the water will be to press this canvas still more iirmly around the leak and prevent the inflow of water during the operation of pumping the water from the hold and making the proper repair of the leak from the inside of the vessel.

The apparatus above described is simple and efficient in construction and operation, may be manufactured in any size to suit the particular vessel in connection with which it is intended to be used, and by reason of the elasticity of its framework will readily accommodate itself to hulls of varying shapes.

Various changes in the form, proportion, and minor details of construction may be re sorted to without departing f rom the spirit or sacrificing any of the advantages of this invention.
