8 Claims.

This invention relates for small boats or canoes having outboard motors.

Among other objects, the invention aims to provide a construction permitting an occupant of a boat to steer it by turning the outboard motor (with the usual propeller and, in some cases, a rudder) Without use of his hands or feet, thereby permitting that occupant to devote his entire attention to manipulating a fishing rod or line. The construction of the invention permits perfect control of steering by merely shifting the position of the operators body relative to the boat; thus one man can steer a boat around logs, snags, sand bars, rocks and other obstructions and can simultaneously manipulate a fly rod or casting rod with both hands.

A further object is to provide a construction which may be installed on'most small boats or skiffs; in fact, the installation may be made by one man withoutspecial skill or tools.

Another object is to provide an attachment adaptable for several different types of outboard motors.

Another object is to provide an attachment for steering outboard-motor-driven boats which is readily disconnected when it is desired to steer by hand in the conventional manner,

Other objects will be apparent from the following description of the preferred form of the invention, togetherwith one of the many modifications which express the inventive concept.

In the accompanying drawing forming a part of this specification, and showing the parts somewhat diagrammatically- V Fig. 1 is a top plan view of the stern of a small boat shown with an outboard motor and the steering attachment of the invention;

Fig. 2 is a section on line 2-2 of Fig. 1 but showing the backrest folded down or closed;

Fig. 3 is a vertical section on line 3-3 of Fig. 1,

the backrest being shown upright as in Fig. 1;

Fig. 4 is an enlarged sectional elevation of the seat showing in dot-and-dash lines how it may be manipulated;

Fig. 5 is a fragmentary vertical section through the seat, on the same scale as Fig. 4;

Fig. 6 is a fragmentary plan view showing part of the seat and its mounting;

Fig. 7 is a detail showing the connection between one end of the cable and the movable seat;

Fig. 8 is a top plan view of a modification;

Fig. 9 is a side elevation of the parts shown in Fig. 8; and 1 Fig. 10 is a detail inper pective of a modification.

Referring particularly to the drawings, the reference character ll designates a boat'or skiff of any ordinary construction, and I2 is an'outboard to steering attachments motor clamped upon the stern of the boatandhaving a substantiallyyerticalpropeller shaft I 3 and a steering lever I4. 11-, will bejunderstood that a propeller (and usually, a rudder) are'mounted at the lower end of shaft l3; these parts are not shown as they form no part of the invention. The boat may be propelled and steered by the outboard motor assembly when the motor is running and the lever 14 is turned by the hand of the operator, it being understood that the outboard motor may be turned through a wide angle in order to effect such turning, or in the event a swing of the motor is made, as is possible with some motors, a reversal or backing of the boat will take place.

Mounted on the stern seat l5 of the boat is a relatively fiat rolling seat I 6 on which the operator sits. This seat may include a cushion, not shown. Two or more parallel rails I1, I 8 are made fast to seat [5. For convenience these rails may be angle irons, as shown, or they may be small I- beams or have other shapes. A pair of shafts I9, 20 are fixed crosswise of rolling seat I6 on the underside, and a pair of grooved rollers 2 I, 22 are rotatable on each shaft I9, 20, said rollers preferably being ball-bearing to cut down friction to a minimum. By this means the rolling seat 16 may roll on the stern seat 15 crosswise of the boat, its own weight, plus that of the operator, holding it on the rails. A backrest 23, which may be cushioned, is adapted to stand upright as shown in Fig. 3, in which position it is held by a pair of

braces

24, 25, or it may be folded in the manner shown in Fig. 4 and when so folded will lie horizontally on top of the rolling seat I6.

Braces

24, 25 have enlarged ends or

heads

25a, 25a and slide through eyelets or

ring guides

26, 27 swiveled respectively on the end of the backrest and on the end of seat I6, so that the change from the vertical position of Fig. 3 tothe folded position of Fig. 4 is facilitated. If necessary additional members (not shown) may be used to prevent relative shifting of the backrest longitudinally of seat l6. These and other minor details of construction are omitted as the invention is not concerned with them. Pins 28 are fixed at each end of the rolling seat I6 and project outwardly for engagement by the overlapping end edges of the backrest to support the same in the folded position.

The rails ll, l8 may be secured together in parallelism by a pair of

angle bars

29, 30 welded or otherwise fixed to the ends of the rails to form a rectangular track frame which is rigid and has a'width equal to that of a standard wooden boat seat. This track frame may be drilled (not shown) and screws or bolts may be passed through registering holes drilled also in the boat seat It, to secure the track frame rigidly yet permit its removal when desired. Lugs 3|, 32 welded or otherwise secured to the sides of the rails may project downwardly at spaced points, in contact with'the front and rear edges of seat l5 to guide the attachment when it is shown), said pins being telescoped' in the ends of the tubular arms as shown and being welded.

or otherwise immovably fastened to the track frame at said corners. At their outer or free end the

tubular arms

33, 34 carry small pulleys 3-1 which are either pivotally mounted as shown. or are swivel pulleys, as will be understood without illustration. These pulleys 31 guidea wire cable 38 one end of which is attached to a pin 39 (Fig. 4) fixed to the seat edge. Cable 38 passes around a pulley 3! to and completely around the lower part of the casing or crankcase of the outboard motor l2 and back around the other guide pulley 3] to a turnbuckle 39? which is screwed on ahook 49 (Fig. 7) and also on an eye-bolt 4i screwed or otherwise secured to the bottom edge of the backrest 23. Cable 38 may be disconnected from hook 40 whenever its tension is diminished by turning the turnbuckle 3%. If desired a tension spring '(not shown) may be employed with cable 38 to keep it in tension so that it will have the necessary frictional engagement with the crankcase.

In Figs. 8 and. 9 I show a slightly different construction wherein a steering sector ring 50 is bolted on an outboard motor of the type known as a Martin 60, which makes a 180 turn for reversing the boat. The cable 38 is in two parts which are received in a groove 52 in the steering sector ring and are attached thereto and cross each other and then extend to their connections with the seat. In this construction the

arms

33, 34 and pulleys 31 are not necessary. In Fig. l0 I show a modification comprising two U-shaped brackets 55 connected together by a strap or bar 55, the brackets fitting over the transom of the boat and supporting the same pulleys 31 which in the previous formwere on the ends of tubular arms. Cable 38 is guided around these pulleys 3:1. Various other changes and modifications may be resorted to within the cop of the appended claims.

K am a re f the B s o d nt o- 1,133,738 dated ll/larch 30, 1915, and do not claim such a construction; but I claim:
