20 Claims.

This invention relates to a mechanical rowboat toy and particularly to the type wherein two separate oars are used in oar locks and actuated by a mechanical figure containing actuating mechanism capable of being wound up by manipulating a part of said figure. W

The main object of theinvention' is to provide a toy of the character indicated wherein a mechanical figure is designed to simulate natural body movements of a person rowing a boat.

Another object is to provide by the nature and construction of the mechanical figure a toy having oars capable of movement and also to make it possible to insert or remove the oars at will While preventing actual loss of the oars or displacement thereof when in use.

It is furthermore an object of the invention to introduce improved means for detachably connecting the arms of a mechanical figure with the handle portions of the oars in a highly efficient mannerto resemble universal joints. 1

It should also be mentioned that it is an object to have a toy of this character of such simple and practical construction that it will be very reasonable to manufacture and capable of being sold at a low figure. In the accompanying drawings forming part hereof, the invention is illustrated in a practical embodiment.

Hence,

Fig. 1 is a perspective View of a mechanical rowboat toy made according to the present invention embodying the salient features thereof, a mechanical figure or automaton being shown seated in position for operating the toy;

- Fig. 2 is a partial, vertical and longitudinal central section of the toy showing certain features of construction including the oar operating mechanism. 1

Fig. 3 is a transverse section of the toy through the central well, wherein the automaton is located.

4 is a plan view.

Fig. 5 is a same view oars removed.

Fig. 6 illustrates details of the connection between an arm of the automaton and the end of the oar intended to be connected thereto preparatory to assembling.

Fig. 7 illustrates the same details in assembled condition.

Fig. 8 is a perspective of crank 43 and Fig. 9 is a perspective of the head, neck and elastic connected thereto. r I i Throughout the views the same reference numerals indicate the same or corresponding parts.

In the practice of my invention a toy model with the automaton and of a boat generally 'indicatedat I, and made .of wood or sheet metal; is provided with a central well 2 in which an automaton generally indicated at 3 is' located, and fromwhich well said automaton' extends upwardlyin the'form of -a body 5 or torso surmounted by a head 5 which serves as a. winding key for winding up the mechanism as will presently appear. l g

Of course the boat if made of sheet metal may have a central opening corresponding to the well -2 and be otherwise hollow throughout,'but a solid wooden block is for some purposes preferable as it is. quite easy to drill or cut out. A central well 2 will readily serve the purpose of the present invention in economical manner. 15

Upon the upper surface 6' of the boat is fixed an anchoring plate I for the mechanism terminating at the sides in a pair of opposite oar locks 8,8. The two prongs 9 and III of each ofthese oar locks are slightly expansible' in=resilient manner by. virtue of a slot II whi'chsplits said prongs apart and enters in upon the anchor plate a short distance at each side thereof, the resulting resilient condition of each oar lock allowing oars similar to I2, I2 to have the shanks thereof gently forced down between each pair of prongs so that the cars will snap into place and thereafter'be free to move in the wider portions of the space between said prongs while being prevented from dropping out of the car locks f'rom between'the prongs of said oar locks, due to the fact that the same have sprung back into position so as to partly envelop said oars.

The anchor plate projects downwardly with'in the sides of well 2 in the form of a yoke generally indicated at I3, having the sides I4, I4 and the transverse bottom portion I5 which is pierced by a slot l6 running transversely of the boat as a whole while the sides I4, I4 are provided with, corresponding apertures IT for receiving pivot means adapted to extend into corresponding holes IS in the sides I9 of the body 4 of the automaton. .Ho-rizontal pins would serve to project into holes I8 upon which the automaton might rock but it. is preferred to use an arch wire member 22 having side portions 20, 20 with horizontal opposite projections 2| in assembled condition of the device into the holes I8 in-the automaton from the holes I! in the anchor yoke. The arch wire is preferably resilient so that it tends to clamp against the sides I4, I4 of the yoke while the main looped portion of the wire may conveniently lie within the confines. of the well 2 in boat I, thus avoiding the loss of pivot pins and also fa- 55 cilitating assembling or disassembling of the automaton.

Extending from both sides of the body portion 4 at the upper portion thereof is a pair of similar arms 23, 23 which terminate in disc shaped ends or hands 24. The handle ends 25 of the oars are longitudinally slotted as at 26 while the disc shaped ends 24 are of slightly smaller diameter than the preferably hollow interior 2'! of said handle ends. When an oar is to be connected with one of the arms it is but necessar first to dispose the oar forwardly of the arm with the handle extending toward the arm, when it will be possible to introduce the disc 24 of the arm into the slot 26 after which it is but necessary to turn the car toward its respective side of the boat and press the same down between the pron s 9 and ID of the oar lock 8 upon said side of the boat when it will be found that the car has been not only connected with the arm but also assembled upon the boat so that both the arm and oar lock serve to retain the oar captive and under perfect control of movement of the arm involved. The arms 23' are capable of reciprocating in such manner as to raise and lower the cars as will presently be explained but it is noteworthy that the width of the slots 26 are designed to be a loose fit upon the narrow tapered portion 28, while the disc 24 upon the endof each arm is a loose fit within the round interior 21 of the car handle, with the result that the connection is substantially a universal joint allowing vertical and horizontal movements of the oars while the arm carries out corresponding motion and causes said movements, said joint by its nature allowing free movements in any direction within the range of movement possible for the arms and oars.

Returning momentarily to the anchor plate, it might be stated that it is preferably shaped from a single piece of metal which may be divided at the front and the rear along the top of the boat as at 29 and 33, the plate being secured to the body of the boat by screws 3 3| or by any other suitable means.

However, the body portion or torso 4 of the automaton may be made of a single sheet of bent metal comprising a rear portion 32, the shoulder portion 33 and the front portion 34, which is continued downwardly and bent under the figure at the bottom at 35 while terminating in a hook portion 36 engaging against the exterior of the lower end of the rear portion 32. If the torso is assembled by drawing the front and back together while the hook portion or flange 36 is allowed to clear the lower end of the back portion 32 it will be but necessary to press the front and backparts together and permit the flange 36 to be caught outside said lower end of the back, when the body portion will remain assembled in form. .Each side I 9 has a clearance space out out below the shoulder portion 33 and is partly over-lapped by a flange 31 which is bent forwardly from the rear portion 32. Upon the upper edge of flanges 31 rests the knife edge portions 33 of the arms 23, 23- which are interconnected by a transverse member 39 having within the body 4 of the automaton a pendently swingable leg 40 rigid therewith. This pendent leg is formed with a clearance slot 40 which extends substantially the entire length of the leg, but the resulting subdivisions of the leg are joined at the bottom by a forwardly directed flange 4| adapted to engage against a crank arm 42 of a driving crank generally indicated at 43 having an axle portion 44 passing through and centered in the bottom 35 of the body 4, so that said crank is rotatable in said bottom about a vertical axis. Above the crank arm 42 is fixed or formed a loop 45 to which a resilient member 54 such as a spring or an elastic member of rubber or the like is preferably attached for driving said crank, while the lower portion of the crank terminates in a crank arm 46 exteriorly below the bottom 35 of the automaton or figure and is adapted to engage in the transverse slot H3 in the bottom I5 of the lower pendent portion l3 of the anchor plate.

It will now be obvious from the immediate foregoing description that if the crank 43 is caused to rotate about its local axis in the bottom 35 of the automaton, the crank arm 42 will during rotation tend to repeatedly swing the leg 40 connected with cross member 39 and the arms 23, 23 rearwardly by engaging against the connecting flange 4|, while the lower crank arm 46 will cause the entire body of the automaton to swing back and forth about its pivot 2| so as to allow said crank arm 46 to oscillate from side to sidein slot l6. Of course, the flange 4| could be extended forwardly and a transverse slot cut therein within which the crank arm 42 can oscillate in order to positively drive pendent leg 43 both back and forth but this expedient when once mentioned'is so obvious as to be unnecessary to illustrate.

Beneath the shoulder portion 33 of the automaton body 4 is located upon each side an upwardly directed lug 4! immediately within the sides I 9, said lug being connected into a unit by a transverse member 48 provided with a tongue 49 which extends into the slotted portion of leg 40 so as to guide the latter in its movements. Centered in said cross member 48, and extending upwardly from it, is a resiliently expansive tubular member 50 which is split along one side at 5| and surmounted by the head 5 of the figure which is secured thereto, the mentioned tubular member being retained against loss by a flange 52 formed upon its lower end below member48. Passing through said tubular member in a transverse direction is a pin 53 which may serve simultaneously for securing the head 5 rigidly to the tube 50 and as an upper anchorage for the elastic member 54 which is secured at the lower portion to the loop 45 of the crank 43. Due to the fact that the tube 50 is split it can form as it were a tubular spring which tends to expand in the hole 55 of the transverse member 43 so as to produce a sufficient degree of friction which the elastic member 54 cannot overcome when it is twisted to a reasonable degree.

The head 5 of the figure serves as a winding key by which to wind up the elastic member 54 by turning the head clockwise while preventing the arms and oars from moving by interposing a finger in front of the oar handles with the result that the elastic 54 acquires a high torsional tension. When the boat is lowered into the water and allowed to float thereon and the oars freed, the crank 42 will rotate about its vertical axis at 44 in the bottom 35 of the torso or body 4, causing the entire automaton to rock back and forth about the horizontal pivots 2| due to the oscillation of lower crank 46 in slot l6 of the anchor plate, while the crank arm 42 will also cause pendent leg 40 to swing back and forth by engaging against the lower flange 4| thereof so as to raise and lower arms 23, 23. The result is that when the automaton is swung backwards the arms remain substantially stationary in 7 5 raised position due to the fact that .flange 4| of the pendent leg 40 will follow up by gravity the forward rotation of crank arm 42 becausethe cars have been. designed to extend with the greater part of their weight outside the oar looks so as to tend to raise the arms by their weight. The rotation of crank or crank arm 42 about 44 as an axis is based on the fact that when the torso 4 is considered as the housing or casing for the operating parts, the axis of the cranks 42 and 46, as well as the axis of the anchoring hook 45 andv elastic member 54 must be considered in reference to said torso. The axis of 44 is actually intended to be directly in line with the elastic 54 and the axis of member 50 as well as of the torso itself,- but while more accurately shown in Fig. 8, said part 44 is drawn slightly to the left in Fig. 2 in order to avoid confusion with parts 20 and 2|. When the figure has reached its rearmost position, the crank arm 46 has also reached its extreme position towards .one end of slot I6 and is about to return towards the other end in said slot and thereby rock the figure forwardly, the crank arm 42 also beginspositively to swing pendent leg 40 rearwardly which causes the arms 23, 23 to be lowered in positive manner so as to positively lower the handle portions of the cars and raise the outer ends of the oars while the figure is being rocked forwardly, this motion causing the outer ends of the oars to be swung rearwardly while clearing the water. 'When the figure is again about to rock towards the rear, the crank arm 46 which is now located towards the end of its oscillation and about to return in the opposite direction in said slot 16, the crank arm 42 swings forwardly so as to release the lower portion of leg 40 from its rearmost positionwith the result that the weight of the oarswill immediately raise the arms so that the outer ends of the oars are dropped into the water and. in this position the figure beings to rock backwards while said outer ends of the oars are driven forward in the water.

The rocking of the automaton and the raising and lowering of the cars in a manner very closely simulating the natural rowing of a person in a rowboat will be continued until the elastic member 54 has lost its torsional tension,'so that a new winding of the same by means of head 5 will again cause the automaton to operate as described.

The oars are preferably made of one piece and in fact the mechanism as a whole including the automaton, oars and anchor plate are preferably made of, sheet metal although other metal or materials may serve, but the invention is designed to be economically made and assembled from as few simple parts as possible, one of the simplest and yet surprising features being for example that the arms which have but a small space for free play operate perfectly upon the knife edge (which need not be sharp or particularly prepared) so that an easy and practically frictionless and balancing movement of the arms results.

As has already been mentioned, the boat may be made of solid wood etc., merely drilled out to accommodate the anchor plate and the automaton, or it may be made entirely in the form of a hollow sheet metal hull without any anchor plate, the flange with the car looks of the present description as well as the lower portion [3 with side portions I4, l4 and traverse bottom portion l5. being formed in a similar manner to the present anchor plate.

Nevertheless, it should be mentioned that the crank arm which operates the arms of the figure is disposed at an angle with the crank arm which cooperates with the slot in the bottom of the anchor plate so that the movements of the automaton run exactly opposite to the raising and lowering of the arms but this angular relation between the crank arms serves to bring about the dropping of the oars immediately before the figure is about to swing backward. In case the head is wound in a counter-clock-wise or backward direction the figure will tend to row backwards because the movements will naturally occur in opposite rotation.

Manifestly, variations may be resorted to and parts used without others within the scope of my invention as interpreted by the following claims.
