KARL JOSEPH SEGK, OF MAINZ, GERMANY.

MECHANIGALLY-OPERATED BOAT.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed November 3, 1905. Serial No. 285,791.

To all whom it may concern:

Be it known that I, KARL J OSEPH SnoK, mechanician, residing at Mainz, No. 3 Gymnasium street, in the Grand Duchy of Hesse, Germany, have invented new and useful Improvements inMechanically-Operated Boats, of which the following is a specification.

My invention relates to boats which are propelled by paddles, operated by a series of mechanism from a common bar or bars actuated by manual or motor power, and by setting this bar, the course of the boat may be directed straight ahead, or backward, side- Wise to right or left, around its vertical axis, or around a point in its longitudinal axis, and may be used for pleasure or other purposes.

The advantages of my improved boat over others are, its easy management, the power necessary to propel the boat is reduced to a minimum, that it can be used without a rudder and that under the most trying conditions it can not capsize.

My improved boat consists as it may happen of two boats secured together by bridge pieces, or of only one boat carrying the propelling mechanism, comprising one or more sets of paddles operated by chainor sprocketwheels from sprocket-wheels at the center of the boat, a disk adjustably fastened to said center wheels,a hand-bar adjustably secured to said disk, and means for controlling the individual paddles to bring and maintain them in the direction, which is at right angles to the stroke.

My invention further consists of improvements hereinafter more fully described and pointed out in the claims.

My invention will be more fully understood taken in connection with the accompanying drawings forming part hereof, and

in which:

Figure 1, is a top view of my improved boat, showing the twin-boats bridged together, the paddle mechanism, the operating sprocket-wheels, disk and hand-bar, also a rudder with means for operating the same, and anchor With hoisting device. Fig. is a longitudinal section on the line 22 of Fig. 1. Fig. 3 is a crosssection on the line 3-3 of Fig. 1. Fig. l is a top-view of the paddle operating mechanism, with the hand bar. Fig. 5, is a central section of the operating mechanism shown in Fig. 4. Fig. 6, is an elevation of the paddles arranged in pairs, and supported from the bridge pieces by means of a stud and a cross-bar. Fig. 7, is a top-view of the paddles, their supporting bar and the mechanism for maintaining the individual paddles in normal actuating position. Fig. 8, is a section showing the mounting of a paddle upon its supporting bar, and Fig. 9, is a section showing the stud and paddle-supporting bar on the line 9-9 of Fig. 8.

Referring now to the drawings for a further description of my invention, a and a are the twin-boats coupled together by means of the distanceor bridge-pieces (Z, the distance at the fore-end between the twin-boats is smaller than at the rear in order to reduce the resistance of the water acting 011 the sides of the twin-boats, when the boat is being propelled. Each of the twin-boats is provided with recesses c, which may be closed by lids Z), and these recesses are provided with foot rests for the crew; other arrangements for the seating of the crew and other persons may of course be made.

On top of the distance or bridge pieces (Z, is secured a plank c, on which all the operating mechanism for the boat is mounted. To propel the boat, paddles f operating only in one direction, are provided, and are actuated and controlled as hereinafter more fully described. These paddles f are mounted at the ends of a paddle-bar g of which one or more may be arranged and pivoted in the longitudinal axis of the boat in the plank c, in the drawings, four of such bars 9 with two paddles f each are shown. These paddlebars g are mounted on short shafts 72,, Figs. 6, '7 and 8, in any preferred manner and are oscillated about their centers by chainor sm-ocket-wheels i secured to said shafts b. An oscillating motion is imparted to these shafts h from the sprocket-wheels j, 70 mounted loosely on the stud Z at the center of the plank e. Mounted loosely on the same stud Z and above the sprocket-wheels y, 70 is a disk we having a rim 1?, with series of notches 0, for a purpose to be presently described. Above the disk is further mounted loosely on the stud Z a hand-bar 29 having lugs to engage one of the said series of notches 0, and to keep the lugs engaged in said notches, a spring is employed in a well known manner. Normally the sprocket-wheels j, 70, and disk m are held together or in operative position by means of a removable pin Q engaging the distance blocks 7- between the wheels j, is and disk m, and when the hand-bar p is oscillated the two or more paddle-bars 9 move in unison therewith.

The middle part of the hand-bar is partly cut away, in order to display the word indicating the direction in which the boatis to be propelled. In Fig. 4, the hand-bar p is set on Forward, and both paddle-bars with paddles are operated to propel the boat in that direction. If the disk m with the sprocket-wheels j, 7:; still coupled together by the pin are rotated 30 degrees and the lugs on the hand-bar engage the notches 0 the slot in the hand-bar displaying To right, then the proportion of the diameter of the chain wheels 2' to that of the chain wheels j, 76, being as 1 to 3 the paddle-bars g assume the normal direction in line with the longitudinal axis of the boat, and the latter will be propelled or pushed to the right. A similar result will be obtained but the direction of the boat is changed to left, if the hand-bar p. is set at To left that is to say, turned 90 from the Forward position, and the bar 29 may be set in any notches between those just mentioned, to propel the boat at any angle desired. To propel the boat backward, the paddle-bars g are turned 180 degrees, by turning the disk m and wheels j, 180 degrees. To propel or swing the boat about its center, or a vertical axis through the stud h the coupling-pin q is lifted and the lower wheel is is turned by means of a lever s engaging the lower-wheels 7c, the pin q engaging the hole 26 in the wheel 70 this brings the paddle-bars again in line with the longitudinal axis of the boat, but the paddles work in opposite direction, as will be more fully described. The boat may be rotated toward the right or left in this manner, according to whether the wheel is is turned either toward the right or left. To propel the boat about the center, for instance of the rear paddle-bar g, and with the front of boat toward the left, the wheel 70 is entirely uncoupled and the wheel with disk m is coupled to the hand-bar 2) so as to display To left.

At the ends of the paddle-bars g are secured sleeves or journal-boxes t, in which stems u are rotatably mounted, Figs. 7, 8 and 9, the paddles f are provided with hingestraps o and mounted on the trunnions 10 secured to the said stems a. To hold the paddle f in operative or active position, the paddle is provided with a slanting offset 00 corresponding with the beveled lower end of the said stem, Fig. 9, so that the paddle when moved against the water, will be in vertical position and when moved away from the water, it will float over or with the same.

To keep the paddle when in action in the proper direction or what may be called the eficient position, that is at 90 degrees'to the direction in which the boat is to be propelled,

the short shaft 72. of the paddle-bar g is provided with a cross bar 2 and this bar is held by the helical spring .2 normally in line with the longitudinal axis of the boat.

The stems u are provided with arms 10, as shown in Figs. 7 and 9, extending on opposite sides of a paddle-bar g and the ends of these arms 10 are connected to the respective ends of the bar y by means of connecting rods 11 so that when the paddle-bars g are oscillated, the paddles f maintain an eiiicient position in relation to the water, which is at 90 degrees to the course of the boat.

The cross-bar 3/ is provided with notches 12 and the paddle-bar g with studs 13 to limit the oscillatory movement of the paddlebar when in rowing action. \Vhen however the paddle-bar g is reversed 180 degrees the wedge-shaped ends of the studs 13 and the spring a will allow the cross-bar y to pass over the studs 13.

The boat may also be provided with an anchor 1A and if such is employed it may be operated from the handle-bar p and the sprocket wheels 2' and 7c, in such case the shaft h is provided with another sprocketwheel 15, driving a wheel 16, ratchet-wheel 17 and winding-drum 18 for the anchorchain, which are all secured to one shaft journaled in the end of the plank e. A pawl 19 engaging the ratchet-wheel 17 is pivoted to the plank c and caused to engage with the ratchet-wheel 17 by a spring. The sprocketwheels 2' and 15 may be coupled together by a pin, when the anchor 1 1 is to be raised, the boat moving in such instance toward the anchor.

Having thus described the nature and ob jects of my invention, what I claim as new and desire to secure by Letters Patent is:

1. A boat composed of twin-boats coupled together by bridge-pieces, a plank in the center midway between the twin-boats, one or more paddle-bars rotatably mounted on said plank, a hand-bar pivoted at the center of the boats to the said plank, means for connecting said hand-bar with said paddle-bars, paddles trunnioned to the ends of the paddle-bars and back-stops for said paddles, substantially as and for the purpose set forth.
