UNITED STATES PATENT OFFICE.
CHARLES BERNHARD, OF NEW YORK, N. Y.
PROPELLER.
SPECIFICATION forming part of Letters Patent No. 351,152, dated October 19, 1886.
(No model.)
To all whOm it may concern.-
Be it known that I, CHARLES BERNHARD, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Propellers, of which the followingis aspecification.
This invention relates to a device for propelling boats, the peculiar and novel construction of which is fully pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure l is an end view seen from the rear, in which the rudder and its supports have been broken away. Fig. 2 is a horizontal section in the line a; :r, Fig. 3. Fig. 3 is a plan or top view.
Similar letters indicate corresponding parts.
In the drawings, the letter A designates the main frame, which is secured to traverses B B, which serve to hold two boats, C O, rigidly together.
D is the secondary frame carrying the propelling mechanism E and the steering-gear F.
Its forward end is connected to the main frame by a rope or chain, a, which passes through rings or staples b on its under surface, the outer ends of these ropes being secured to similar rings, 0, in the main frame. Its rear end is supported by two ropes or chains, (Z, the outer ends of which are secured to rings a in the main frame, and which pass over guides f to a Windlass, g, mounted in the secondary frame. The object of this construction is to adjust the secondary frame, which, as above described, carries the propelling mechanism,
so that the latter may be placed in the exact position in relation to the boats that will most effectually develop its utmost propelling capacity, whether the boats to which it is attached are loaded, and consequently low in the water, or empty and high above the water. If used on canals of limited depth, it will also obviate what has hitherto been a serious objection to the employment of propelling mechanisms on these water-ways namely, that of disturbing the bottom of the canal by the propellers when the boats were loaded down. This adjustment is accomplished by the windlass g, on which the ropes or chains d are wound until the desired position of the propeller is obtained, in which position the secondary frame is then secured by pins h, which pass through holes 6 in the uprights j of this frame, and rest on a beam, 70, secured to the main frame and extending through the secondary frame from one boat to the other, and also serving to hold the secondary frame against any endwise motion.
In the example shown in the drawings the Windlass and the other means for adjusting the secondary platform are shown attached to its rear end only, while its forward end is loosely attached to the main frame by the rope or chain (1.,- but it is obvious that an adjusting device may be attached at both ends of the secondary frame, if it is found necessary.
The propelling mechanism may be of any construction usually employed; but I prefer to use two propelling-screws, Z Z, carried by a shaft, m, having its bearings in the secondary frame. This shaft carries a chain-wheel, 12., over which a chain, 0, passes, which connects it with the shaft 1), which may be revolved by any motor. lVhere steanrpoweris not applicable, I impart the necessary revolving motion to the propeller-shaft by means of levers q, carrying pawls 1', which act on ratchet wheels 8, mounted on the shaft 16. This shaft is connected to the shaft to by gear or chain Wheels, or both, and the latter carries bevelgears which mesh into a similar gear on the shaft 1). By actuating the levers q motion is transmitted to the propelling'screws as above described, and as shown in patent granted to me, dated August 19, 188i, and numbered 308,7 97
The rudder G is mounted on the rear traverse, B, between the two boats, and carries a tiller, 1), the outer ends of which are connected by ropes or chains 10 with thefoot-lever a, con nected to the secondary frame by a pivot, I). To insure additional rigidity, guy-ropes may be stretched between the main and secondary frames, as shown at c.
What I claim as new, and desire to secure by Letters Patent, is
1. The combination of tivo boats, front and rear traverses connecting the latter, a main frame, a vertically-adjustable secondary frame locatedin the space between the two boats,
the lower end of the secondary frame below the main frame and traverses, substantially as described.
2. The combination of two boats, front and rear traverses rigidly connecting the boats, a main frame connected with the traverses, a vertically-adjustable secondary frame carried by the main frame in the space between the boats and between the traverses, and a revolving propeller-shaft journaled in the lower end of the secondary frame below the main frame and traverses, substantially as described.
3. The combination of two boats, front and rear traverses rigidly connecting the latter, a main frame mounted on the traverses, a vertically-adjustable secondary frame carried by the main frame, a revolving propeller-shaft journaled in the lower end of the secondary frame, a rudder journaled in the rear traverse between the two boats, and means for actuating the rudder, substantially as described.
4. The combination of two boats, a main frame connected with the adjacent sides of the boats, a vertically-movable secondary frame carried by the main frame in the space between the two boats, a windlass, arranged on and movable with the secondary frame, ropes or chains at, extending from the wind,- lass and having their ends respectively secured to opposite sides of the main frame, and guides f, around which pass the ropes or chains in the passage to the main frame, substantially as described.
"In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
