Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 28th May, 1902.

COMPLETE specifications relating to the undermentioned applications for Letters Patent have been accepted, and are open to public inspection at this office. Any person may, at any time within two months from the date of this Gazette, give me notice in writing of opposition to the grant of any such patent. Such notice must set forth the particular grounds of objection, and be in duplicate. A fee of 10s. is payable thereon.

No. 13847.—25th July, 1901.—JAMES CHARLES NEWELL, of Palmerston North, New Zealand, Pianoforte-tuner. An improved music-leaf turner, with da capo movement.

Claims.—(1.) In music-leaf turners, a number of spring lever-arms A pivoted upon a spindle B, each one being attached to a pulley C, two springs E being connected at one end with each pulley C, and fixed at the other end to a sliding frame G. Each pulley C is secured to one of the lever-arms A by a vertical steel rod D, by which means the lever-arms A can be turned upon their pivot to the right or left at the will of the operator. Each lever-arm A is provided with means for gripping the leaves of music, and with means whereby the lever-arms A may be released one by one and allowed to turn upon their pivot as specified. (2.) In music-leaf turners, a number of spring lever-arms A, provided with means for gripping the leaves of music, in combination with escapements M, such escapements M consisting of vertical rods N sliding in fixed frame H, the bottom ends being provided with forked horizontal arms with upper projecting pins O that release and retain the spring lever-arms A one by one as the vertical rods N are moved up and down, as specified. (3.) In music-leaf turners, a number of spring lever-arms A, pivoted, and with pulleys C and sliding frame G, in combination with escapements M such as referred to in claim 2, and with cords Q or wires running over pulley R and secured at one end to the bar connecting the vertical rods N of the escapements M, and at the other end to the slide G; the back levers L (whose attachment is shown in Drawing No. 2), also the cords V which are attached to the ends of the back levers L, and which when pulled downward by the knee lever cause the slide G to move and the escapements M to be raised. (4.) In music-leaf turners, escapements M (such as referred to in claim 2), in combination with two compression-springs S, which are secured to the vertical sliding rods N by pins T, so that the escapements M are returned to and kept in their normal low position by the compression-springs S after the strain on the wire Q is removed, as set forth. (5.) In music-leaf turners, escapements M (such as referred to in claim 2) having upper projecting pins O, by which the lever-arms A are held within the escapements, and having also lower spring pivoted pins P standing back from the upper pins O the exact thickness of the lever-arm A, and which allow the latter to pass within the escapements M. (6.) The general arrangement and construction and combination of parts in my improved music-leaf turner (with da capo movement) as described and explained, and as illustrated in the drawings, and for the several purposes set forth.
