AUTOMATIC SPRING-WINDING MECHANISM FOR MECHANICAL MUSICALJNSTRUMENT DEVlCES.

SPECIFICATION forming part of Reissued Letters Patent No. 12,289, dated November 22, 1904.

Original No 697,754, dated April 15, 1902. Application for reissue filed January 29, 1904. Serial No. 191,224- I i To (all 107mm if nt/q concern:

Be it known that we, HERBERT E. Sunnrs and ILLIAM F. Coornn, citizens of the United States. both residing at Chicago, in the county of (look and State of Illinois, have invented new and useful Improvements in Automatic Spring-finding Mechanism for Mechanical Musical-Instrument Devices, of which the following is a specification, reference being bad to the accompanying drawings, forming a part thereof. 7

Our invention relates to automatic springwinding mechanism for mechanical musicalinstrument devices, and has for its object to provide an improved and simple automatic winding mechanism for winding and keeping wound a spring-motor to be applied to the rolling and rerolling of a perforated tunesheet for automatic musical instruments and automatic musical attachments.

'VVith these ends in view our invention consists in certain details of construction and combination of parts, such as will be hereinafter fully set forth and then specifically be designated by claims.

In the accompanying drawings, which form a part of this application, Figure 1 is a view, partly in side elevation and partly in section, showing our improvement; and Fig. 2, a sec tional elevation of the spring-motorand windin g-spring in their proper assembled positions. Fig. 3 is a detail View of a portion of the winding devices shown in Fig. 1, on an enlarged scale, designed to show the frictioncluteh device. Fig. 4 is'a detail edge view of the disk and clutch device shown in Fig. 3.

Similar numbers of reference denote like parts in all the figures of the drawings.

I 1 is any suitable and ordinary casing, within which is journaled the motor-shaft 2. 3 is a drum hung loosely around this shaft inside the casing, and 4.. is the motor-spring, the inner. end of 'whichis secured, to the shaft 9 by any suitable means, as a screw 5; (shown in dotted lines,) while the outer end of said spring is secured to the wall of the drum by any suitable-means, such as a screw 6.

7 is a disk having one of its hubs, 8, secured to the shaft 2, while to the other hub, 9, of this dis'k is secured the hub 10 of a second disk 11, so that it will be clear that the shaft 2 and disks? 11 are rigidly securedtogether, so as to revolve in harmony.

12 is a wheel whose hub 13 is loosely journaled on the hub 8, and I4 is a similar wheel whose hub 15is loosely journaled on the hub 11. The wheels 12 14 are recessed or cut away at one side, as shown at 16 and 17 in each instance, and the disks 7 11 extend within these recessed'portions, so that the peripheries of the disks are very close to the inner peripheries of the recesses. The peripheries of these disks are provided with little wedgeshaped pockets 18, as shown at Fig. 1 in the instance of the disk 11, and resting within these pockets of this disk 11 are little balls 19, while corresponding balls 20 rest within the pockets of the disk 7. The diameter of these balls is greater than the widthof the space between the peripheriesof the disks and. the ocripheries of the recesses 16 17 at all points except where these pockets are located, so that it will be clear that when the wheels are turned in the direction of the arrow, as shown at Fig.

1, there will be no wedging or binding between these'wheels anddisks; but when said wheels are turned in a reverse direction the balls will be wedged tightly between the peripheries of the disks and recesses, and thereby cause the wheels and disks to revolve in harmony- Small springs 21 21 are secured to the sides of the disks, the extremities of these springs being extended behind the halls, so as i tion. although we prefer the form shown and described.

springs 4, 22, and 23 are the usual volute springs, and the springs 22 23 are each stronger than the spring 4:, and the springs 22 23 are wound in a direction reverse to the direction in which the spring 4 is wound, and when the wheels are turned in the direction indicated by the arrow at Fig. 1' the springs 22 23 will be wound, so that they will impart to the hubs of the wheels a tendency to revolve in a direction reverse to that indicated by the arrow. Therefore should the wheels be turned in the direction indicated by the arrow and then released the springs 22 23'would cause the wheels and shaft 2 to revolve in a direction reverse to that indicated by said arrow and the motor-spring 4 would be wound. The wheels are each connected with any suitable treadle or pedal device, so that at the powerstroke of such treadle or pedal the corresponding wheel will be turned in the direction indicated by the arrow, so as to wind the corresponding spring 22 or 23, while at the return movement of such pedals or treadles, respectively, the motor-spring will be wound by the treadle and passed over suitable pulleys 28 29 and then attached to the periphery of the wheel 14. The cord 27 is of course connected at one end with the periphery of the wheel 12 and then passed over a pulley 30 and another pulley similar to the pulley 28 (but not shown) and attached to the other trcadle or pedal. It will be understood that the two pedals will be operated in the usual manneri. a, beingdepressed alternately, one being held down while the other is.risingand it will be understood also that the clutch device in each of the wheels 12 and 14 operates as a detent, preventing the reverse movement of the shaft 2 .and disks 7 and 11 during the reverse movement of the other of'said wheels corresponding to the rising movement of the pedal with which it is connected. We have shown and described two of these wheels and two sets of the more powerful springs, since this is an advantageous construction. We do not wish, however, to be limited to thisidouble construction, since other and familiar detent means to hold the winding action gained at each stroke maybe used without departing from the main or essential feature of our invention.

The drum 3 carries a gear 31, wbichmeshes with the usual train of gears, by means of which the unrolling of the perforated tunesheet is effected, and the transferring of the power of the motor-spring to the usual rewinding-roll is accomplished by the ordinary 1 gear-shifting mechanism, which-we have not shown and which will require no illustration or description herein.

It will be understood that an important purpose of the springs 22 and 23, arranged so as to wind the motor-spring by reacting from the winding to which they are subjected by the pedal connections, is to avoid the danger of overwinding the motor-spring which arises when such motor-spring is wound bydirect= action of the pedals, whichare operated primarily for pumping the bellows and which fo r that purpose may require to be operated much more than would be necessary for keeping the motor-spring wound, and in the draw-' ings, therefore, the pedal 25, which is showm has a connecting-rod 32, and it will be understood that both pedals are similarly provided in this respect and that said rods 32 would extend to and operate the pumper-bellows. (Not shown.)

There are several forms .of spring-motors that are used in automatic piano-players, and we have illustrated a well-known form of motor in which the motor-spring winds continuously. Also spring-motors are commonly used in which no-drum whatever is employed, one extremity of the motor-spring being connected in any suitable and ordinary manner with the perforated tune-sheet-unrolling devices.

We therefore do not wish to be limited toany particular form of spring-motor, sincethegist of our invention resides in the broad idea of, winding the motor-spring by means of the actionof a more powerful spring at the return movement of the pedal.

Having thus described our invention. what we claim as new, and desire to secure by Let-I ters Patent, is v 1.
