Title: Improved Means for Automatically Turning the Leaves of Music.
Inventor: BUDGE GEORGE SYMONS
Filed: 1903-10-26
Granted: 1904-07-21
Abstract: 23,165. Budge, G. S. Oct. 26. Leaf-turners.-A device for automatically turning the leaves of music consists of a number of arms mounted on a spindle and having at the ends spring clips to engage the sheets. The arms are turned over to the right against the action of springs and are held by catches which are released one at a time by depressing a key. A base-board a is fixed vertically to the music rest of a piano and carries a frame b in which is mounted a spindle c. Arms d turn loosely on the spindle and are connected by springs f to the frame b. Each arm projects beyond the one above it and carries a spring clip at its end. On a spindle a are loosely mounted lever catches j equal in number to the arms d, and having extensions k which engage pins l on the arms. The arm m of each catch j is pressed by a spring n against a spindle o, on which are pallets p, one opposite each catch j. On the upper end of the spindle o is a ratchet-wheel having as many teeth as there are arms d. This wheel is turned by a pawl lever attached to a rod t, Fig. 5, which is connected by a bell-crank lever v with a lever plate w. On this plate rest pivoted arms x, y, bearing finger-pieces at their ends. On depressing the arm y, the rod t is pulled against the action of a spring 3, and the lever pawl turns the ratchetwheel through the space of one tooth, and is carried back by the spring 3 over the next tooth. The spindle o is thus turned, and one of the pallets p depresses its arm m and allows the pin l to escape from the projection k. The arm d is then pulled over to the left by the spring f. Should it be desired to repeat a page, the arm x is depressed. The spindle o is thereby turned sufficiently to release the arm d but not enough to let the pawl lever slip over the next tooth of the ratchet. A small cylinder fixed to the spindle o is marked with numbers showing the positions of the palletsp.
