This invention relates to mechanical attractions especially for stores and in particular to a musical display device for seasonal exhibition as at Christmas time in which a figure representing a robed organist simulates playing on an organ,

in a pleasing and life-like manner.

A universal objection to many mechanical toys is the presence of a jerky, uneven movement far from life-like. Some inventors have tried to '-overcome this fault by making the movements absolutely smooth and regular but this in turn is also unnatural and produces an inanimate monotonous effect which is not pleasing. Therefore the main object of this invention is to provide a mechanical figure having pleasing animated movements which are neither mechanically jerky nor monotonously inanimate.

A particular object of the invention is to provide a figure which closely simulates the movements of a human being in playing a musical instrument such as a piano or an organ. Another object is the provision of a figure which has a smooth and non-jerky motion when operated by a simple mechanical means such as a crank.

Still another object is to provide an attractive front for a radio or phonograph before which a mechanical figure moves as if playing the instrument represented by the front and to provide a simple mechanical device for translating the ro- Figure 1 is a perspective View of a pipe organ and a player operating the same in accordance with my invention.

Figure 2 is a perspective view of the mechanism used to operate the players hands and feet;

Figure 3 is a view of a modified detail. Referring to Figures 1 and 2, it wil be seen that the hands IU of the figure H are supported just above the keyboard I2 of the pipe organ I 4 by means of supports l5 and I6 which reciprocate toward and away from each other to give the figure the appearance of playing the organ. The supports preferably have upright pins H and i8 thereon to be received in sockets l1 and I8 provided in the hands I0 of the figure with sufficient looseness of engagement to give the desired lost motion. The feet 20 of the organist II similarly engage supports 22 and 23 located under the keyboard in about the same relative position as the ordinary foot pedals of an organ. When thesepedals or supports are operated out of unison with the upper supports they give the feet of the doll a movement simulating closely that of a real player.

I have discovered that the jerky movement so common in mechanical toys is still further eliminated by providing yielding pads 24, preferably of sponge rubber, between some and preferably all the joints of the figure. The torso 32 of the organist is secured to a rocker 30 and is'held in a yieldingv upright position on the bench 26 by means of elastic cords 28 so as to provide alimited amount of freedom. A still simpler form is to afiix the sponge rubber cushion 34 to the block 30 and the bench 26 as by suitable adhesive material.

The elastic cushion 34, preferably of "sponge rubber, is positioned between the rocker 30 and the bench 26 which construction permits the body of the figure to sway slightly while the hands and feet are being moved which swaying makes the playing remarkably realistic. The thighs and legs 36 of the figure are joined together and are secured to the rocker by means of elastic cords 38 of usual construction and the upper and lower portions of the arms are held together and to the body 32 by means of similar elastic cords or tendons 39.

In the rear of the organ is arranged a device for giving the supports l5, I6, 2-2 and 23 different harmonic motions so that, while the hands and feet of the organist shall move in unison, these movements shall not always be in the same. di-

rection or at the same speed. As will be seen in Figure 2, the diagonally positioned supports l5 and 23 are connected together by means of the sloping member 4|] and that similarly, opposite supports l6 and 22 are connected together by the sloping member 42 which crosses member 40. The supports in the present instance are shown as connected to tubular sliders 44 which are con strained to move in parallel paths by the rails or bars 46 rigidly secured one above the other in the uprights 48, this being the preferable construction.

Each pair of diagonally connected supports, one member operating an arm and the other operating a foot, is adapted to be given harmonic motion by its respective connecting rod 50 or 5] in response to rotation of a double crank 52 which may be operated by the motor of a phonograph or any other available means. In practice I use the organ front as a screen or shield for a phonograph 54 and drive the crank 52 by means of a belt 55 which encircles a pulley 56 driven by the phonograph motor and a second pulley 51 on the crank shaft. Obviously the crank may be actuated by any other means without changing my invention. The rod 50 pivoted to the sloping member 42 somewhat above its center is connected to the middle arm 59 of the crank while the corresponding connecting rod is connected to a point somewhat below the center of the diagonal member 40 and is pivoted to the end 58 of the crank which may be of the same or different length than the middle arm 59 of this crank, but preferably the two arms are of somewhat different lengths so that the travel of the diagonal members 40 and 42 are likewise different, the left or bass arm of the figure having a greater length of travel than the right or treble arm, or vice versa, if desired.

In Figure 3 is shown a modified form of support for the doll which is more economical than the bench and eliminates the necessity of the rocker and rubber cushion. The torso 32 of the figure may be rigidly secured to the top of the piano stool 63 which is supported by a helical spring 64 to permit limited motion of the doll.

As illustrated in Figure l the figure is pleasingly represented as a girl organist whose robe is in front of the bench as in the figure but may hide the helical spring 64 in the modified and simpler form shown in Figure 3. It will be understood that while the invention covers the entire combination illustrated and also equivalent structures I- also intend to protect the individual items as well, for example, a figure with stationary legs but employing the arm movement shown.

The movement of the arms and legs of the figure can probably be best understood by assuming that the middle arm 59 of the crank is directly above the shaft of the pulley 51, at which time the end 58 is projecting to the right as seen in Figure 2 so that the connecting rod 5| is slightly above the central pivot of the crank. Assuming the pulley 51 is turning clockwise, the left hand support I5 is at one limit of its motion as the end arm 58 is about on dead center. The right hand support I6 and with it the left foot support 22 will be moving toward the right at almost its highest speed. Just prior to the position shown in Figure 2 the two connecting rods are nearly parallel and both hands and both feet are moving to the right. In the position shown the end 58 of the crank is pointing to the right, the left hand support l5 and the right foot support 23 are at a dwell and consequently substantially stationary as the rod 5| is at dead center. At such time, however, the right hand and left foot of the figure are moving to the right at approximately maximum speed;

At 90 from the position shown the right hand support I6 has reached the right limit of its travel but the left hand is still moving to the left. From this point on both hands and both feet of the figure are moving to the'left at approximately the same rate of speed and this movement continues until 180 of travel from the position shown in Figure 2 at which time the connecting rod 5| is again on dead center and consequently the left hand support |5 and the right foot support 23 have reached their left hand end of travel and are substantiallystill altho the other hand and the other foot of the figure are moving toward the left at'maximum speed. From this point back to 360 the two hands of the figure are approaching each other but'the feet are moving away from each other. Because of the crossed position of the diagonal members 40 and 42 the two hands of the figure will be closest together when the feet are farthest apart as at 5( and likewise, thehands will be farthest apart when the feet are closest together as at 230. While in some of the models I drive the connecting rods 50 and 5| by cranks revolving at different speeds, it will be noted that practically the same effect is had by the simpler mechanism illustrated in Figure 2 in which, as just shown, the hands of the figure are sometimes moving in the same direction and are sometimes moving in opposite direction and one hand will be moving at almost maximum speed when the other hand is substantially still, thus simulating quite closely the movement of thehands of a living organist.

What I claim is:
