6 Claims.

My invention relates to musical toys or instruments which have a plurality of differently tuned tone members and means for activating these members selectively in any desired sequence whereby any desired melody can be played.

Objects of my invention are to activate the tone members by striking means contacting the surfaces of the tone members while by-passing these surfaces in a direction that is substantially tangential with respect to the path of the striking means and to the surface of the contacted tone member, thereby to produce clear, loud and pleasantly ringing tones, and to make this particular contact possible by Striking means arranged so rotatably that the rotary path leads these means into substantially tangential contact with the tone members.

- Other objects are to hit each tone member to be activated several times at each single hand stroke of the player, thereby to produce tremolant tones, to blend the individual tone impulses into one pleasant tremolant tone by the mentioned ringing quality of the individual tones, and to make these effects possible by a structure which allows passage of the striking means at the contacted tone surfaces whereby the striking means can continue rotating and can strike the tone members repeatedly.

Further objects are to provide tone members having the shape and the superior tone quality of bells, to provide different tones by using bells of different diameters, and too to provide rotatable striking means of variable radial length whereby the same striking member can contact the smallest bell and can by-pass the largest bell.

Still further objects are to attain the mentioned results with simple and inexpensive means, and to provide a musical toy of superior tone effect that can be made and assembled easily and quickly.

'Still other objects and advantages will appear from the following description of an exemplifying embodiment of my invention, from the appended claims and from the accompanying drawing in which:

Fig. 1 shows a cross-section of an illustrative embodiment of my invention, this cross-section being taken along the line ll in Fig. 2.

Fig. 2 shows another cross-section of the same embodiment, this cross-section being taken along the broken line 2--2 in Fig. 3.

Fig. 3 shows a top view of the same embodiment.

Fig. 4 shows a side view of an activating unit which is a part of the embodiment shown in Figs. 1 to 3, this view being seen in the direction of Fig. 1.

Fig. 5 shows a cross-section taken along the line 55 in Fig. 4.

Fig. 6 shows a side view of a striking member which may be used instead of the striking member shown in Figs. 4 and 5.

Figs. 4 to 6 are represented on a larger scale than Figs. 1 to 3.

The shown embodiment comprises a supporting structure constituted by a casing 3 which may be provided with openings 4 for the passage of tone waves. A shaft 6 is affixed to the casing 3 and crosses its inner space horizontally. A number of sleeves, some of which are indicated by 1, surround the shaft 6.

Tone members, some of which are indicated by 8 and 9, are shaped like bells and hav central bores through which the shaft 6 passes. These tone members are supported by this shaft in a row and are held in spaced positions by the sleeves. Each bell is tuned to a different tone, preferably by providing the bells with different diameters. The drawing shows seven bells. But I desire it understood that any number of tone members sufficient for playing a melody may be incorporated in the embodiment, for example, 8 or more tone members.

There may be one or more units 1 l for ringing or activating the tone members. Each unit may have the structure shown in Figs. 4 and 5. This structure comprises a frame or housing 12 having a top l3 supported by the casin 3, a shaft I 4 rotatably carried by the frame 12, an operating mechanism for rotating the shaft l4, and rotatable striking means. The latter comprise an arm 15 affixed to the shaft l4 and extending therefrom radially and a striking element 16 which is movably connected to the outer end of the arm 15, for example, by an axle I! passing through bores of the arm I5 and of the element [6 and provided with end heads l8 which prevent separation of the parts l5 and 16. Preferably, the distance between the two end heads I8 is large enough to provide some clearance between the parts i5 and IS.

The axis of the axle I1 is not radial, but preferably parallel to the shaft l4 and is eccentric with respect to the striking element l6 whereby the striking member constituted by this element and the arm l5 has a variable radial length. When the striking member rotates, the centrifugal force holds the element H3 in its most outward position as shown in Figs. 1 and 2. In this position, the striking element [6, forms an outer or radial extension of the arm 5. When, during the rotation, the striking elements hit. a tone member, the element It turns about the axle I! so far as necessary to allow passage of the striking member at the tone member whereby the striking member can continue rotating and can contact and activate the tone member repeatedly.

The arm I may have an integral extension forming another arm I5 positioned symmetrically at the opposite side of the shaft I4. This other arm I5 may be also provided with a striking element I6 and an axle I'I whereby the striking member is balanced about the shaft I4, and the number of contacts with the tone member is doubled. When the striking member does not rotate, the striking elements I6 depend from the axle I I as shown in Figs. 4 and 5.

The operating mechanism is so constructed that one stroke of the players hand or finger rotates the shaft I4 in one direction only and several times around whereby the striking member rotates in a circularly closed path. In the shown embodiment, for example, the unit I I is provided with a handle or key 2| positioned over the casing 3 and afiixed to a vertical stem 22 which passes slidably through the top I3. in a bottom opening of the housing I2 is affixed to the lower end of the stem 22 and engages a pinion 24. 'This pinion and a toothed wheel 25 are co-axially affixed to a shaft 25 which is rotatably in openings 27 of the housing I2.

The openings 21 have an elongated shape forming a short vertical slot. The rack 23 has a horizontal projection 28 to which the lower end of a coiled spring 29 is affixed. The tension of this spring urges the rack, the handle, the pinion 24, the wheel 25 and the shaft 26 into the shown uppermost position in which the shaft 26 rests in the upper ends of the openings 21. When the handle 2| is pressed down, the shaft slides down in the openings 21, and the wheel 25 engages another pinion 3B which is aflixed to the shaft I4. This shaft is rotatable in bores of the housing I2. Further depression of the handle and, thereby, of the rack 23 causes rotation of the pinion 24 and of the wheel 25 which, in turn, rotates the pinion 3d and the shaft I4 whereby the striking member rotates in the direction of the arrow 3! in Fig. 1.

When the pressure on the handle 2| ceases, the rack and the shaft 26 return into their uppermost position, and the wheel 25 is disengaged from the pinion 30. This pinion and the striking member continue rotating in the direction of the arrow 3| until they are braked by friction and by contacts with the tone member.

The units II are so arranged that their operative means allow selection of the path of the striking means in such a manner that the striking means can contact and activate any desired one of the tone members. This selection maybe made possible in several manners. For example, the unit may be so shiftable that it can be brought'into proper position to or into registry with any of the tone members. Or several units may be so arranged in fixed positions that each unit is in registry with one of the tone members. Or some tone members may be contactable by a shiftable unit and other tone members by fixed units.

The shown embodiment illustrates the latter combination between shiftable and fixed units. The tone members positioned in Fig. 2 at the left side of the casing 3 from 8 to 9 can be activated by a unit II which is shiftable parallel to the shaft 6 or along the row of tone members, the top i3 of the unit I I having an I-shaped:

A rack 23 guided at the right side of the tone member 9 can be activated by units II which may be identical to the shiftable unit, but are held in fixed positions.

When a unit is in registry with a tone member, the shaft I l has a distance from the tone member which is so measured that the tone member reaches slightly into the rotary path of the striking element whereby rotation of the striking element brings the same into contact with the tone member. These contacting bodies are sufficiently movable away from each other to allow passage of the striking element at the tone member. This movability may result from resilience, for example in the manner which will be described later, or from a movable connection of one of the contacting elements with the supporting structure. An example of such a movably connected element is the striking element I6 which is connected to the arm I5 and, hence, to the supporting structure by the axle I1. 'I'he striking member comprising the arm I5 and the element I6 has a maximal radial length sufficient for contact with the bell of smallest diameter and has a minimal length smaller than the distance of the shaft I4 from the largest bell.

Resilient evasion of the striking element may be produced, for example, by the following structure. Instead of the striking member comprising the arm I5 and the element I6, the striking member 33 shown in Fig. 6 may be used. This member has a central disk 34 affixed to the shaft I4 and two arms 35 formed by fiat springs and extending radially from the disk 34 whereby the length of these arms is shortened when the springs 35 bend resiliently.

The rotating striking element by-passes the tone member while striking and activating the latter. During this passing contact, the striking element moves tangentially to the contacted surface of the tone member and continues rotating in a circularly closed path.

I desire it understood that my invention is not confined to the particular embodiment shown and described, the same being merely illustrative, and that my invention may be carried out in other ways without departing from the spirit of my invention as it is obvious that the particular embodiment shown and described is only one of the many that may be employed to attain the objects of my invention.
