PROPELLER.

SPECIFICATXON forming part of Letters Patent N o. 473,017, dated April 19, 1892*. Application and July 16, 1891. serial No. 399,693. (Nb model.)

To @ZZ whom, it may concern:

Be it known that I, HENRY PETERSEN, of New York, county and State of New York, have invented a certain new and useful Improvement in Propellers for Vessels,of which` the following is a specification.

This invention relates to propellers for steam or similar vessels; and it consists in propeller-wheels located at the side of the vessel and rotated from the main propeller` wheel shaft; and it further consists in means for lubricating the bearings.

I will describe a mechanism embodying my improvement, and then point out the novel features in claims.

In the accompanying drawings, Figure l is a transverse vertical section of a vessel, showing my improvement. Fig. 2 is a top view of the propellers, showing the casings or tubes and a portion of the vessel in longitudinal section. Fig. 3 is an enlarged view, partly in section, of one of the propellers. Fig. 4 is an end view thereof. Fig. 5 is a horizontal section of a bearing employed. Fig. 6 is a transverse section of said bearingand certain lubricating mechanism. Fig. 7 is an enlarged detail partly in section. Fig. 8 is a partial vertical section showing lubricating mechanism for the propellers.

Referring by letter to the drawings, A designates the hull of a vessel, and A shows a portion of a shaft rotated in the usual manner to revolve a propeller-wheel (not shown) at the stern of the vessel.

B B designate pairs of propeller-wheels located at the outer sides of the hull A below the water-line and rotated from the main propeller-shaft A. I have shown the propellerwheels B B of each pair as mounted on a shaft d, which has bearings d in spiders d2, secured within a tubular casing A2, which is open at its ends. The bearing for the forward wheel is in the rear of the wheel. The forward propeller-wheel B of each pair is preferably smaller in diameter-than the rear wheel B, and the tubular casing A2 has a taper, the smaller end being forward. By tapering the casing A2, as shown, it offers less resistance to the water. The casings A2 may be secured to the sides of the vessel in any desired manner-such, for instance, as by metal bands a2, surrounding the casings and bolted to the vessel. It will be seen that the forward end of the hub of the forward wheel against longitudinal or vertical movement in the sides of the vessel for the passage of the eccentric-rods C. These bearings D are cylindrical in form and oscillate in bearingblocks D', whichv are secured in openings in the sides of the vessel and have horizontal openings d through them. A rod Chas alongitudinal movement through a transverse hole din its bearing D. It is obvious in this construction that when the rods C are in operation they will havea longitudinal movement through the bearings, and the oscillation of the bearingspwill accommodate them to the oscillating movements of the rods, and the bearings are water-tight.

As the different bearings cannot be reached for oiling in the usual manner, I have provided a means for automatically lubricating the bearings, which I will now describe.

I Will rst describe the crankpin bearings. (Plainly shown in the enlarged view, Fig. 7.) The crank-pin e is secured to the crank c and passes through an opening in the eccentricrod C, and an oil-box in the form of a cap E is removably engaged by a screw-thread or Yotherwise to a tubular boss extending from the side of the rod C, and through which the pin e also passes. A pipe E', secured to the rod C, communicates with the interior of the oil-box E. The pipe E has a telescopic connection with a pipe e', passing through and secured within an opening e2 in the bearing D.

F is an oil-vat located Within the vessel A and having a tube f, communicating through its bottom with the inner end of the pipe e. As the tube fis stationary and the pipe e has an oscillating movement with the bearing D, I connect the tube and pipe by means of movable joints f. The oil-vat F is preferably IOO provided with a Weighted piston f2, which by its downward movement forces the oil to the bearing.

I have shown the above-described lubricating mechanism as connected with the crankpn of one pair only of the propeller-Wheels; but it is to be understood that the other crankpin is to be lubricated in the same manner.

As a means for lubricating the bearings a for the shafts c, I provide the oil-vats G Within the vessel, from which pipes glead through the sides of the vessel to pipes g', securedvto the casings A2, as plainly shown in Fig. 8. From the pipes g branch pipes g2 lead to oilholes in the bearings a.

My invention not only serves to increase the speed of a Vessel, but it obviates to a great extent the rocking motion often found in a propeller having only the stern Wheel.

Having described my invention, What I claim isf 1. In a vessel, the combination, with a tubular casing secured to the side thereof, of propeller-wheels having bearings supported in said casing, means comprising an oil-vat Within the vessel, having pipe connections Wit-h the wheel-bearings, for automatically lubricating the bearings, and means for rotating the Wheels, `substantially as specified.

2. In a vessel, the combination, with the main shaft, the propeller-wheels, and the eccentric-rods, of the bearings for said rods, consisting of the transversely-perforated cylindrical bearings D and the blocks D', Within which the bearings oscillate, substantially as specified. 3. The combination, With the oscillating bearing, the eccentric-rod, and the crank-pin, of the oil-box for said pin, a pipe communi- Veating with the interior of said box, a pipe XVitnesses:
