MUSIC-LEAF TURNER.

Patented July 17, 1906.

' Application filed February 16,1906. ileiialllo.301,415.

To all whom it may concern:

Be it known that I, IRA L. GooDRrcH, a citizen of the United States, residing at Cupertino, in the county of Santa Clara and State of California, have invented new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

My invention relates to music-leaf turners. Its object is to provide a leaf-turning device which can be attached to any musical instrumen'tfsuch as a comet or a piano, and by which'the leaves are turned separately, either back or forward, by a push-key.

The invention consists of the parts and the construction and the combination of arts, as hereinafter more fully describe and claimed, havingreference to the accompanying drawings-,in which- Figure 1 is a perspective view of the inven tion applied to themusic-rack of a piano. Fig. 2 is an elevation, partly in section,.of same. Fig. 3 is a plan view of the segmental mutilated gear. Fig. 4 is a front view of the same. p a

A represents a bed-plate which is ada ted support may be'a part of a win instrument,

like a comet, or it may be the music-rack onv the piano. This bed-plate has a flange 2 at one end with a slot 3 and a pin 4 at the other end. The music leaf turning attachment 7 has a base B, which has a tongue or tang'part 5 to fit the slot 3 and a perforation 6 to re ceive the pin 4. A screw 7, carried by the bed-plate, is adapted to lock the attachment in opera ive position.

The usic-leaf-turning arrangement comprises a segment 8, which is pivoted in the ase B. This segment carries three gearsegments 9, 10, and 11. Each of these gears is adapted to engage successively a corresponding pinion 12, 13, and 14, which pinion operates respective rock- shafts 15, 16, and 17. Shaft 16 is a central one and has a gear 13 fixed directly to it. Gear 12 is mounted on a sleeve 18, which has an offset arm in which the shaft 15 is brazed or otherwise made a part thereof. Gear 14 is carried by a sleeve 19, which has an ofiset arm in which the shaft 17 is rigidly mounted. Sleeves 18 19 are concentric with shaft 15 and all turn independently. Rock-shafts 15., 16, and 17 have respective lateral arms 20, and the arms 20 and the vertical shafts are provided with suitable spring-clips 21 to hold a loose sheet of music 22. The segment 8 is operated by any suitable means, as the pivoted stem 23, having the push-button 24. Stops 25 limit the arc of movement of the arms 20 in either direction. These stops are shown as carried by the top plate C.

When the push-button 24 is out to its farthest limit, the three arms 20 will lie side side. Pushing it a. third of the way in wi I operate the gear 12 to rock the shaft 15 and turn the first sheet of musics Pushing another third of the way in on the push-key will cause the gear 10 to rock the shaft 16 and turn the second sheet, &c. Pulling out on the key turns back each sheet of music separately. ventlon is that-any sheet can beturned positively in either direction by reciprocating the ke -stem roperly.

anifestly there may be any desired number' of gearsegments and corresponding pinions, sleeves, shafts, and sheet-holding means.

Havingthus described my invention, what I claim, and desire to secure by Letters Patent is 1 ;In a music-leaf turner, a suitable support, a rotatable art journaled therein and provided with a p urality of successively-ar ranged segments disposed in different planes, a rock-shaft provided with a pinion, a sleeve concentric with the rock shaft and turnable independently thereof 'and provided with a pinion, a second sleeve concentric with the first sleeve and turnable independent thereof and provided with apini on, saidsleeve having ofiset arms, music-leaf-holding devices carried by said rock-shaft and said arms, said One important feature of this in-' several pinions arranged in difierent planes and engageable successively by the said segments.

.2. A music-leaf turner comprising a suitable support, a rockable part j ournaled therein and provided .with a plurality of succes- .sively-arranged gear-segments different planes, a plurality of pinions coaxial wlth each other and independently turnable and 'engageable with respective of said ear-segments, a shaft connected direct wit one of said pinions, sleeves surroundin the shaft and connected with the other pmions, said sleeves havin ofiset arms, shafts carried b said arms an arranged substantially para lel with the first-named shaft, lateral pro'ections on said several shafts, and leaf-hol ing means on said rojections and shafts.

3. A musiceaf turner comprising a suitable support, a rockable part j ournaled therein and provided with a plurality of successively-arranged gear segments in different planes, a lurality of pinons coaxial with each other and inde endently turnable and each engageable with one of said gear-segments, a shaft connected direct with one of said pinions, sleevessurrounding the shaft and connected with the other pinions, said sleeves having offset arms, shafts carried by said arms and arranged substantially parallel with the first-named shaft, lateral pro ections on said several shafts, leaf-holding means on said projections and shafts, a push-key connected to the rockable part to rotate the same, and stop means in the path of said lateral rojections to limit the rotative movement of the shafts.

4. A music-leaf turner com rising a suitable su port, a unitary rocka le part journaled t erein and having a plurality of successively-arranged gear-segments, said segments being dis osed in different planes and each being rigi with the rockable part, a rockshaft, sleeves concentric with each other and with the rock-shaft, said sleeves and rock-shaft independently turnable, and said sleeves having offset arms, gears on the shaft and on the respective sleeves engageable successivel b the ear-se ments on said rockable-part, leaf-ho ding means carried by said shaft and the arms of said sleeves, and means to limit the rotative movement of the sleeves and shaft.

5. A music-leaf turner comprising a suitable support, a rockable part journaled therein and having a plurality of successively-arranged gear-segments, a rock-shaft, sleeves concentric with each other and with the rockshaft, said sleeves and rock-shaft independently turnable, gears on the shaft and on the respective sleeves engageable successively by the gear-segments on said rockable part, said sleeves having lateral projections, shafts carried by said roj ections and arranged substantially parallel with the first-named shaft, lateral arms on the'several shafts, leaf-holding means on the several shaft-arms, and means to rock said rockable part.

6. A music-leaf turner comprising a suitable support, a rockable part journaled therein and having a plurality of successively-arranged gear-segments, a rock-shaft, sleeves concentric with each other and with the rockshaft, said sleeves and rockshaft independently turnable, gears on the shaft and on the respective sleeves engageable successively by the gear segments on said rockable part, said sleeves having lateral projections, shafts carried by said projections and arranged substantially parallel with the first named shaft, lateral arms on the several shafts, leaf -holding means on the several shaft-arms, stop means to limit the rocking movement of said arms, and a push-key connected to the rockable part to rotate the same.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
