JOHN GARTNER, or noonnsrnn, NEW YORK.

SEA-GGING VESSEL.

PECIPICATION forming part of Letters Patent No. 299,128, dated May 27, 18 84.

Application filed October 22, 1883.

To aZZ whom it may concern 1 Be it known that I, JOHN GARTNER, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Sea-Going Vessels, of which the following is a specification.

My invention relates to improvements in sea-going vessels of that class in which it has been proposed to use side propellers in addition to the ordinary stern propeller; and the object of my invention is to construct a vessel of this class that will acquire a much greater speed, and can be easier controlled than vessels as ordinarily constructed.

My invention consists of pillow-block castings constituting the bearings for the propellershafts, constructed to form part or sections of the plating or skin of the vessel and conforming to the water-lines thereof, whether the said pillow-block castings be combined with side or stern propellers. It is important that the bases of the pillow-block castings conform to the Water-lines of the recesses in which the side propellers are arranged, and that the pillow-bearings proper project from the surface of the castings longitudinally in line with the side walls of the vessel, while conforming to the contour of the walls of the recesses and to the side water-lines of the vessel, which enter and emerge from said recesses on each side of said surface pillow-bearings; and these recess pillow-block castings so constructed are formed with integral cut-waters in line with the pillow-bearings. The stern pillow-block casting conforms to both sides of the stern of the vessel, and the pillow-bearing proper thereof is placed between the skin or plating, and may be made in one or two parts or sections, suit ably bolted together, all of which will be more fully described hereinafter, and specifically pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a side elevation of the forward part of a vessel, showing one of the side propellers and its pillow-block castings; Fig. 2, a bottom view of the same; Fig. 8, a bottom view, on a smaller scale, showing the two side propellers and the stern propeller; Fig. 4, a

Fig. 14 is a erosssection of the same on the line 1 2 of Fig. 13.

In each side of the vessel A, forward of midship, is constructed a recess, B, for the reception of a propeller, G 0. Each recess is so formed as to conform to and mergeinto the regular water-lines of the vessel, so as to offer no obstruction to the free passage of the vessel through the water. The propellers are secured to shafts c c, which have their bearings in pillow-block castings D D. These pillowblock castings are constructed of cast-iron, composition, or other suitable metal, and are secured to and form a part of the skin of the vessel, to which they are riveted or bolted. They may be provided with recessed flanges dd, so that the thickness of metal of the skin fits into said recesses and forms a perfectly smooth surface. The joints are then properly calked to prevent any possible leakage. In the bearing of these pillow-block castings are arranged the ordinary sleeves and bushing with proper lignum -vitze or other suitable packing, and at the inner ends are placed the usual stuffing-boxes, c e. The shafts c c are each provided with the well-known collar thrust-bearing E E, as shown in Fig. 4L; and,if found necessary, similar thrust-bearings may be applied at the other ends of the shafts which extend to the engines.

Each propeller is preferably operated by a separate engine, so that in steering one may run in one direction while the other runs in the opposite direction. They maybe provided with couplings, so that they can be run together. Each pillow-block casting has formed with it, at the end facing the propeller, a sharp projection, f, which forms a cut-water, and

. guides the water toward the sides of the pillow-block castings. The cut-water gradually merges into the base of the pillow-block castings, so as to form no angles or projections. Said pillow-block castings are each provided with a suitable lubricating device, as shown at 9, Fig. 7, which extends through the inner wall of the vessel, so as to be easily accessible from the interior.

In the stern of the'vessel is placed the sternbearing pillow-block casting F, made in one or more parts, for the propeller G. This pillow-block casting contains the ordinary lining, bushings, packing, &c., and it is also provided with recessed flanges h, into which the plating or skin of the hull fits, and to it the pillow-block castings are riveted or bolted.

prefer to employ rivets or bolts with countersunk heads, so as to offer no resistance to the speed of the vessel. The sides of this pillowblock casting conform to the contour of that part of the stern to which it is secured at the top and at each side; and it is preferably cast in one piece,as shown in Fig. 14, and is adapted to join the keel and the rudder-post frame.

All the pillow-block castings may be strengthened by brackets or web-ribs on their inner sides, so as to make them very strong and durable,and prevent any twisting or derangement. .Any other kind of'thrust-bearing may be employed instead of the collar thrust-bearlngs.

Some of the advantages of my improvement are that the vessel, by the employment of the side propellers, can be made to answer the helm more quickly and easily; a much greater speed can be obtained than with ordinary vessels only using the stern-propellers, the recesses being made to gradually merge into the regular water-lines of the vessel on each side of the pillow-block castings, forming inlet and outlet passages for the water, and thereby causing the propellers to act with better effect and the vessel to move at increased speed.

The pillow-block castings can be easily applied to a vessel. They can be easily made and repaired, and they are very strong and They can be easily applied to old as well as new vessels, so as to accelerate the speed thereof, by adding the side propellers 5 and they can be easily replaced by new ones, if desired.

The side recesses are preferably formed at a point about a quarter to a third of the ships length from the bow, and they conform to the water-line, as shown in Fig. 11, so as to give a free inlet of the water to the propeller under the movement of the vessel, and allow the water to pass freely out of said recess, so that the side propellers operate in a body of water free from the least churning action. This is avery important matter of my invention, because such construction is of the highest advantage in increasing the capacity of the vessel' for speed. Such construction is-also important in giving the advantage of placing the pillowblock castings practically within the recesses, so that they do not form side projections on the hull. Nor do they offer obstruction to speed. The pillow-blocks proper are raised parts on the surface of a section of the plating or skin of the ship, and these raised parts are curved in lines conforming to the waterlines of the hull, so as to form a way or passage on each side of the raised part into and out of the recess, so that these pillow-blocks, in fact, offer no resistance to the speed of the vessel, while giving the firmest possible bearing and support for the propeller-shaft. The arrangement of the pillow-blocks within the recesses allows the bearings for the propellershaft to be extended into the recesses quite near the propeller, so that there will be a comparatively short length of shaft exposed crossing the recess, and there will consequently be little or no vibration to the shaft.

It has beenproposed to construct sea-going vessels with side propellers arranged in recesses formed in the hull; but, so far as I know and can find, the construction and combination of recesses, propellers, and pillow-block castings which I have shown and described are new, and give advantageous results not possible in the constructions hitherto devised for theemployment of side propellers.

While I have described the pillow-block castings as being separate and forming a part or section of the skin or plating of the vessel,yet it is obvious that while conforming to the waterlines of the vessel they may not necessarily be a part of the skin, but may be bolted to the skin.

I claim 1. In asea-going vessel having side recesses, the combination of the propellers B, arranged therein, with the separate pillow-block castings D D, forming parts or sections of the skin or plating A of the vessel, the pillow-bearings for the shafts projecting from the surface of said castings in lines conforming to the walls of the recesses and to the side water-lines of the vessel, entering and emerging from said recesses on each side of said pillow-block bearings, substantially as described, for the purpose specified.

2. In a sea-going vessel constructed with side recesses and having side propellers arranged therein, the separate pillow-block castings D D, for the propeller-shafts, constructed to form parts or sections of the skin or plating A of the vessel, with the pillow-bearings projecting longitudinally in line with the sides of e to the water-lines, whereof the bearing-projections of said pillow-blocks conform, of the propellers, their shafts passing through the bearings of said separate pillow-castings and the end thrust-bearings E E, substantially as described.

4. In a sea-going vessel, the combination, with a stern propeller, of a pillow-block casting, F, forming a part or section of the skin or plating of the vessel, conforming to the Water-lines of both sides of the stern, having the pillow-bearing extending through it between the plating, and provided with suitable bushings and packing, substantially as described.

5. In a sea-going vessel having both side and stern propellers, the former arranged within side recesses, the separate pillow-block castings D, D, and F, constructed to form the bearings for the propellenshafts and a part or section of the skin or plating of the vessel, conforming to the water-lines of the vessels sides and stern, and provided with suitable bearings, substantially as described.

6. The combination, in a sea-going vessel constructed with side recesses, of side propellers arranged therein, with pillow-block castings forming a part or section of the skin peller shafts of a sea-going vessel, having side recesses for the propellers, conforming to the water-lines of the vessel, said pillow-block castings provided with integral cut-waters, and having their bases conforming to the water-lines of the vessel.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN GARTNER.
