MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed December 20, 1915. Serial No. 67,844.

To all whom it may concern Be it known that l, THOMAS M. JoLLnY, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

My present invention relates to certain new and useful improvements in music leat' turners and analogous devices; and as its primary object, it contemplates the provision of a device of this character, which includes novel means to operate the several engaging arms whereby they may be properly controlled and made to turn the leaves or sheets of music in proper equence and mechanism to cause the releasement or" the engaging arms at the termination of a stroke so that the turned leaves will be thus held in an advantageous position.

Another object of my invention, resides in the provision of improved means which may be so operated as to turn the respective leaves in either direction so that the operator will have complete control thereof, at all times during the operation of the device.

A further object oi my invention is to provide novel engaging arms to be associated with the several sheets to be turned and which are constructed in a manner whereby they will be automatically disengaged from the operating mechanism at the termination of a single stroke.

A still further object of my invention is to provide a device of the type in question that is extremely simple in construction, strong and durable, and highly practical from both the standpoint of the manufacturer and the standpoint of the user; and which, it is believed, may be manufactured at a comparatively low cost.

Various other objects and advantages will become apparent during the continuance of the following description.

These objects are accomplished by such means as are shown in their preferred form in the accompanying drawings, described in the following specification and then more specifically pointed out in the appended claims.

In' the accompanying drawings wherein like charac ers designate like parts throughout the several views;

Figure 1 is a view in front elevation illustrating my invention as in its preferred em lodiment, the several engaging arms being shown in an operative position;

Fig. 2 is a fragmentary view illustrating more clearly the method of mounting the several engaging arms and the relative position of the operating mechanism;

Fig. 3 is a view partly in section and partly in side elevation showing the back or body structure of the device in cross section;

Fig. 4 is a view similar to Fig. 2 showing more clearly the operating mechanism for the several engaging arms;

Fig. 5 is a view in detail of an improved structure that is designed to support one of the operating shafts;

Fig. 6 is a detail view illustrating a member that is designed to cooperate with the several engaging arms and the operating mechanism of the device such as will be he..einaiter fully pointed out;

7 is a view showing the relative disposition oi" the engaging arms at the beginning of the operation of the device.

in reducing" my invention to practice, I first provide a back or body portion 10 that may bei'ormed of any suitable or desirable material, and which carries suitable casings 11 and 12 respectively to contain ordinary clock work mechanisms or any other means designed to operate the several shafts. This back or body portion 10 may be ronstructed in a manner whereby it may be conveniently supported upon a tripod or other similar device, such as would retain the same in full view of the operator, at all times. Although not limiting myself to any specific means to support the device, the re spective casings 11 and 12 may be provided with gudgeons 13 whereby they may be readily connected to a suitable support.

Spaced bearings 14 and 15 respectively mav be arranged on the back or body member 10, substantially in the manner shown, the bearing 14: being designed to support a depending sleeve 16 in proximity to the easing while the other bearing is designed to receive a tubular standard 1'? that is connected in a suitable manner with the casing 12. In order to retain the sleeve 16 and the standard 17 in a secure position at all times and to prevent the accidental dislodgment thereof, during the operation of the device, suitable retaining members, such for instance as designated by the numeral 18 may be provided which are designed to con" nect with the body member 10, substantially in the manner shown. It is pointed out that any number of the bearings 14 and 15 and the retaining members 18 may be provided,

' since this is a mere arbitrary feature and is provided with, first, a rigid shaft 2O,

whose hollowed end ..1 receives the reduced portion 22 of the shaft 19 and, secondly a tubular operating shaft which incases the shaft 20 in the manner shown in Fig. 4. It will be noted that the shaft 20, serves in a sense, as a support for the shaft 19, while the shafts 19 and 23 are free to move independently of each other, if it is so desired. It is contemplated that the casing 11 be provided with clock work mechanism to turn the shaft 19 in one directionwhile the other casing carries mechanisms to actuate the shaft 23 in an opposite direction. Thus it will be seen that the leaves may be turned in one direction, by the actuation of one shaft, and in the other direction, by the operation of the other.

At its lower end, the sleeve 16 is slightly reduced as at 24, the said reduced portion being screw threaded about its periphery so as to receive a similarly formed cap 25; the latter in turn carrying a tubular bearing 26 to fit about the shaft 19 such as shown in Figs. 1 and 2, and at the same time serve as a bearing for the several engaging arms, such as will be presently pointed out. This bearing 26 is also provided with a stepping portion 27, such as shown in Fig. 2, whereby it may be made to support the several engaging arms. In effect, the elements 16, 24 and 25 constitute a tubular shaft reduced intermediate of its ends so as to form a pivot and a bearing shoulder for pivot-ally supporting the arms 39.

At its lower end, the shaft 19 is provided with a projecting actuating arm 28, which, when moved in the arc of a circle, may be made to pass through a slot 29 of the body member 10. This actuating arm may also be engaged with certain elements of the engaging arms, such as will be presently pointed out. Adjacent its connection with the shaft 19, the arm 28 is formed into a suitable eye having its upper surface cut slanting at an angle, so as to provide a cam-face as indicated by the numeral 30 in Fig. 4, which CQDI-fZICQ cooperates with the slanting under side or cam-face of the supporting member 27 so that the arm 28 constitutes a cam-lever having the upper edge of a member 35 as its fulcrum so that the ends of said arm will be raised and lowered slightly during its operation by the shaft 19. The shaft 23 is provided with an actuating arm 31 which may be made to project through a slot 32 of the body 10, and has the underface of its eye portions cut slanting as at 33 so that it will be raised and lowered in the same manner as the arm 28, during its operation by the shaft 23. In this connection it will benoted'that the stop 27 is spaced from the upper end of the standard 17 and the shafts arranged in the said standard, and, owing-to the inclined or slanting arrangement of the opposing faces of the stop and standard the space therebetween is con siderably less at the point farthest away from the backing 19 than it is at the point immediately adjacent said backing. It will therefore be seen that as the arms 28 and 31 when extended in normal position through the slots 29 and 32 are arranged respectively above and below the plane of the restricted portion of this space it will be evident that these arms must move vertically as they revolve so as to properly pass through this restricted portion and actuate the leaf turning arms as will be hereinafter more apparent.

A collar 34 is fixed to the rigid shaft 20 adjacent its upper end, such as shown in Fig. 4, and is provided with a branched guiding member 35, which is inturn connected with the body 10, as at 36 and 37 respectively. This branched guiding member 35 is substantially wedge shaped in cross section and is positioned between the slots 29 and 32 to serve as a guide for the arms 28 and 31 as these arms move in the arc of a circle across the front face of the backing. Being wedge shaped it will be evident that the inclined upper and lower faces of this guide member will permit the necessary vertical movement of said arms, it being understood that the arms engage said faces as they revolve with the shafts 19 and 23.

Eyes 38 are mounted to be movable upon the bearing 26 (see Fig. 2), each of the said eyes being provided with a projecting stud or arm 39. The studs 39 are in turn pivotally connected with the engaging arms 40 as at 41, for supporting said engaging arms while leaf springs 42 are employed to force the engaging arms downwardly. The engaging arms 40 may be of any desired construction; however, in the present embodiment, the same are provided with vertical intermediate end portions 43 adjacent their inner ends, whereby they may be made to engage the respective leaves more effectually, and depending fingers 44 which may be engaged by the actuating arms 28 and 31 at certain times, such as will be hereinafter more fully pointed out.

Members 45 which have their front faces cut slanting as at 46 may be fixed upon the body member 10 in proximity to the arms 40 through the instrumentality of the studs 47 These members may also be provided with suitably curved leaf springs 48 secured in place by rivets as at 49, which springs 48 are designed to engage with the arms 40, at certain times, to hold the said arms in a proper position whereby the fingers may be properly engaged by the actuating arms. WVhen the arms are engaged upon the inclined face of one of the members 45 as shown in Figs. 1 and 2 it will be seen that the fingers of the upper arms will be raised slightly higher than the fingers of the lower arm respectively. Therefore when the low ermost arm is engaged by one of the actuating members 28 or 31 and moved across to the opposite side of the backing 10 the remaining arms will gravitate downwardly along the inclined face of the said member 45 so as to bring the next lowest arm supported thereon into a position where it will be engaged by one of the actuating members on its next movement.

With a view of facilitating the operation of the device, I attach a cable 50 to the actuating arm of the clock work mechanism in the casing 11, while a plunger or rod 51 is con nected with the clock work mechanism in the casing 12. Bell crank levers 52 and 53 respectively are pivotally mounted upon the body member 10 as at 54, one arm thereof being connected with the cable 50 and the rod 51, while their other arm has connection with the actuating cables 55 and 56, which are in turn connected with lugs 57 of suitable finger engaging portions 58. Upon actuation of the finger engaging portion 58 to the right in Fig. 1 the clock work mechanism in the casing 11 will be released so as to cause the actuation of the arm 28 while the other finger engaging portion will release the clock work mechanism in the casing 12, such as will cause the operation of the arm 31.

In the operation of my invention, the several arms 40 are first arranged between the several sheets to be turned and then engaged upon the inclined supporting face of one of the members 45 whereby the finger 44 of the lower arm will project slightly below the fingers of the other arms. Now by depressing the finger engaging portion 58 to the right in Fig. 1, the clock work mechanism in the casing 11 will be released and will cause the positive actuation of the shaft 19 and similar movement of the actuating arm 28. Immediately upon movement, the arm 28 will tend to move slightly downwardly, caused by the contact between its slanting face 30 and the slanting face of the stop member 27 so that after leaving the slot 29, it will move materially below the plane thereof being guided in such movement by engagement with the adjacent inclined face of the branch guiding member 35. As the lower finger 44 is engaged by the actuating arm 28 the leaf turning arm 40 and studs 39 from which the finger depends will be moved to the opposite side of the packing so as to properly turn the leaf engaged therewith. IVhen the arm 40 has reached the end of its stroke, and is engaged with the leaf spring 48 of the other or op positely arranged member 45, it will be forced slightly upwardly as is obvious thereby causing the disengagement of the arm 28 and the respective finger 44. At this time the arm 28 will again be brought in engagement with the guiding member 35 whereby it will be returned to its normal position within the slot 29.

On the other hand, should the operator desire to turn the leaf in the opposite direction, a finger engaging portion 58 at the left in Fig. 1 may be depressed such as will cause the releasement of the clock work mechanism in the casing 12 and the consequent rotation of the shaft 23 and the actuating arm 31. This arm will be moved in practically the same manner as the arm 28 and therefore, it is not believed that further description will be required.

From the foregoing, it will be seen that the device may be employed to effectually turn the sheets in both directions and that simply one sheet may be turned and reversed in accordance with the desire of the operator. In view of the fact that the advantages and novel features of the invention will be readily apparent from the foregoing, further detail description thereof is deemed unnecessary.

In reducing my invention to practice, I find that the form referred to herein as the most practical and preferred embodiment is the most ellicient, but realizing that certain conditions will necessarily vary in concurrence with the adoption of my device, I desire to emphasize the fact that various minor changes in details of construction and the proportion of parts may be resorted to when required, without sacrificing any of the advantages of my invention as defined in the appended claims.
