Specification of Letters Patent.

Patented Oct. 6, 1914.

Application filed November 6, 1913. Serial No. 799,458.

To all whom it may concern:

Be it known that 1, ROBERT E. G. VEIR, a subject of the King of Great Britain, and a resident of the city of New York, SoutlrOzone Park, Woodhaven, borough of Queens,'in the county of Queens and State of New York, have invented a new and Improved lvlechanical Rowboat, of which the following is a full, clear, and exact description.

This invention has special reference to improvements in toys and more particularly to an improved mechanical rowboat.

An object of the invention is the provision of an improved mechanical rowboat, in which a dummy, in the representation of a person, is pivotally supported and adapted to be oscillated by a novel connection with a spring or other motor, mounted in the hull near the stern, or otherwise, while the dummy consists of a novel arrangement of pivotally connected parts to permit a natural movement as in the act of rowing, there being oars attached to the arms of the dummy to cause the propulsion of the boat.

A further object of the invention is to provide in connection with a dummy as described, oars slidably connectedto the arms of the dummy and supported in a novel manner so as to effect feathering action of the oars when the latter are operated, which in conjunction with a suitable motor are designed to cause the continuous propulsion of the boat for a considerable length of time.

A still further object of the invention is to provide a rudder with an arm adapted to be held in an adjusted angular position for causing the boat to take a desired course, so as to adapt the device to be used in a vessel of small area or for directing the boat from one particular place to another, in

carrying out the interesting and enjoyable benefit to be derived therefrom.

With the-above and other objects in view theinvention resides more particularly in the peculiar combination and arrangement of parts, which will be illustrated as a preferred embodiment in the accompanying drawings, and described in the specification.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate correspondingparts in all the views.

Figure l is a plan view of a mechanical rowboat constructed in accordance with the invention, the oars being shown in full lines at the beginning of the power stroke, or vice versa, in dotted lines; Fig. 2' is a vertical longitudinal sectional view through the boat, with certain of the 1 parts in elevation; Fig. 3 is an enlarged side elevation of a fragmentary portion of the boat shown in Fig. 1, with the oar in the position indicated in solid lines in Fig. 1, except that the oars are shown after having entered the water; Fig. 4 is a similar View, but showing the our at the opposite limit of its move ment at the beginning of the return stroke; Fig. 5 is a fragmentary side elevation with the oar shown in its normal position, except that it is disposed in angular relation to me side of the boat; Fig. (3 is a vertical sectional view taken transversely of the dummy support, dummy being shown in elevation.

Referring to the drawings, numeral indicates the hull of the boat, which may be provided with a seat 11 at the bow, and

-a seat 12 at the stern, both of said parts being disposed below the top edge of the hull as shown. A rudder 13 is suitably pivoted or hinged at the stern of the boat and has a forwardly projecting arm 14: adapted by means of a vertical slidable pin 15 carried thereby at its free end, to be engaged with either of a plurality of apertures 16 in the seat 12. These apertures are arranged concentrically relative to the pivot of the rudder, so as to be engaged by the pin whereby the rudder may be held in a predetermined angular position relative to the boat, either to the right or left, or directly rearwardly so as to cause the boat to be guided in a curved or straight path as shall be desired.

Mounted transversely of the hull 10 at point substantially midway of the length thereof is a seat or support 17 for a dummy 18 shown in the representation of a person, it being obvious that it may take various forms. This dummy consists of a pendant upright 19, pivoted at a point below its vertical center to a horizontal pivot member 20 supported at its reduced ends 21, in hearing brackets removably bolted or other wise secured to or through the seat 17. The pendant upright 19 carries at its lower end a counterbalancing weight 23, and also operates through a slot Q-Fthrough the'seat 17, in a direction longitudinalgvith respect to the hull, so as to permit the pendent uplot right to oscillate longitudinally withrespect to the hull.

To cause the oscillation of the pendent upright, the latter is connected to a motor mounted in the hull at the stern of the boat, such a motor being in the present instance shown as. a SPI'lHgJIlObOI'Y'25; having op- -Q/er'ating spring 26 designed to be wound by a key shaft 27 and having a suitable train further consists of a transverse section or cross member 31 mounted on or secured to the pendent member projecting equally distant on either side of the pendent upright, and having rearwardly bent apertured ears at its ends, through which is engaged a pivot 32 for the pivotal attachment of jointed leg imitating members consisting of thigh sections or links 33 and sections or links 34 pivoted thereto. The feet portions 35 of which are designed to be normally disposed in the rear of a cross member or tread piece 36 to cause the parts 33 and 34 to execute a proper pivotal movement when the device is actuated so as to properly illustrate the movements of the lower limbs in the rowing action.

Fixed to-the pendent upright at a space distanced above the cross member 31 is a shoulder forming cross member 37, having at its ends forwardly projecting apertured cars 38, through which a transverse pivot 39 is 1gournaled, while fixed to the extremities 0 said pivot are; arms 40, having apertures 41 near their freeends" as shown. The

oars are indicated by the numeral 42 and are preferably of wood, or similar light material, except at the'points where they are mounted near the inner end, where they are provided with weighted metallic portions 43 serving as counterbalancing weights tending to normally raise the bladed ends of the oars and adapted to cause them'to travel more lightly over-and through the water, during the feathering action, to be subsequently explained. Theoars are supported for 1 feathering movement during their oscillation with the dummy by means of inverted U-shaped supports or oar locks 44, which are provided at central points.

' with depending loops 45 disposed in interlooking" engagement with loops 46 attached to the weighted portions of the cars ornea'r the outer ends of such weighted portions, so as to allow free'up and down movement of the oars during their actuation, aswell as'to permit them to be swung or turned foraction.

wardly or rearwardly with respect to the depending loop to cause them tofeather during their oscillation.

The oars 42 are provided at their inner ends with reduced portions or extensions 47, which slidably engage theapertures '41 and the arms 40, so that during the forward and backward movement of the arms as the body is oscillated, the cars will be similarly operated, the arms traveling or sliding upward and forward on the reduced portions or extensions of theoarsin a'substantially oval path to propel the boat, and during this operation the weighted portions 43 of the cars will cause the arms to swing downwardly ahead of the figure on the return stroke. When the figure commences the power stroke and the body is oscillated rearwardly the arms are raised with the body due to the circular motion of the latter on the pivot 20, and the arms will also bevraised slightly by centrifugal motion due to the quick rearward thrust or motion of the body by the motor on the pivot 39, such motion being transmitted to the oars through the arms as the latter travel in a substantially oval or circular path and the cars enter and are drawn through the water, while the opera tion ofthe oars in the water will serve as governors to regulate the unwinding of the operating mechanism, so that the period of operation of the latter is somewhat lengthened. In the position of the device shown in Fig. 2 the oars will take the position shown in Fig. 3 and the solid'line position shown in Fig. 1, thei dummy being poised forwardly against the action of the counterbalancinr weight 23, and theioars being shifted on their pendant supports or loops, so that the faces of the oars or the blade portions thereof will be presented against the water and caused to exert a propelling 7N During the. continued movements of the dummy with the mechanism, toward the bow of the boat, while still on the power the reduced. portions or extensions of the oars, the latter will be shifted on their inoperative or return strokes b'arely touching the waterin a feathering action, so as to gfl'er no resistance to the advancement of the oat.

From the foregoing description-in connection with the accompanying drawings, it

will be apparent that the mechanical rowboat constructed in accordance with the in-' vention will be strong and durable and not the dummy with the armsfreely sliding on v likely to get out of working order, but more than this the propelling mechanism is so ad ]usted and regulated that the boat will be propelled to the maximum of efliciency with a uniform speed, the power or strength of the motor, in the present instance illustrated as a spring motor, will be conserved so that the boat will operate for a considerable length of time.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
