MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 780,219, dated January 17, 1905. Application filed May 26, 1904. Serial No. 209,838.

To all whmn it 77l/(I/y concern:

Be it known that I, FRANKLIN B. MONAMARA, a citizen of the United States, residing at San Francisco, county of San Francisco, 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 a device designed especially for turning the leaves of music.

It consists in the combination of mechanism and in details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure l is a front elevation, partlyin section, of my invention; Fig. 2 is a side elevation, partly in section, of same. Fig. 3 shows attachment to a piano-rack.

My invention is especially designed for turning single loose leaves which are found in music which may be printed upon an outer sheet folded in the middle and having a single loose leaf lying within the fold and not attached to the outer sheet.

As here shown, A is a plate, base, or frame of any suitable shape or description. It is here shown as provided upon each side with arms, as at 2, and these arms are provided with screws 3, so that when the clamp has been fitted over the lower edge of the music stand or rack these screws may be tightened to hold the parts firmly'in place. In the case of certain piano-racks where there is an upturned edge at the bottom of the rack the clamp may be so designed as to hook over this upturned edge and be held by any suitable attachment.

4: is a yoke or extension below the arms 2, and it is here shown as forming an arch transversely between the said arms. This yoke and the plateAare perforated and form journals for holding and guiding the turning devlce.

The turning mechanism comprises a sleeve 5, the upper end of which fits and is turnable in the plate A. The lower end extends close to the yoke or inverted arch 4E, and the stem 6, by which the turning is effected, extends into the sleeve 5 and is slidable through a hole in the arch 4:, which is in line with the hole in the plate A, so that the two parts practically form the journal about which the device is turnable. From the upper end of the sleeve 5 extends a rod 7, and this rod is in line with the fold of the two outer sheets of the music and also in line with the edge of the single sheet or leaf to which it is to be attached.

The attachment consists of a clamp or clamps, as at 8 8, which are fixed to and project at right angles from the rod 7 and the edge of the loose leaf may be inserted between these clamps, which are long enough to inclose nearly the entire width of the loose leaf or such portion of the width as will make it sufficiently stiff to be turned properly without folding upon itself. I have here shown long clamp-rods 8 near the bottom of the sheet and shorter ones 8 near the top. I have shown foldable clamps, as at 9, connecting with the top of the rod 7, and these may be extended across the width of the sheet or leaf in case it is torn or too flexible to be properly operated by the shorter clamp of the holder. The device being thus in position, it will be seen that the outer sheet foldable in the middle will lie upon the music-rack, and the loose leaf having its inner edge held by the clamps upon the rod 7 will practically lie in its proper position with the inner edge in the fold of the outer sheet.

The turning device consists of the rod or sleeve 6, which is slidable in the hollow sleeve 5, and has a straight slot or groove 10 made in it extending longitudinally from near one end toward the other. Through the yoke or arch L a pin 11 passes and enters the slot 10, so that when the sleeve 6 is pulled downward it cannot turn, but will move in a straight line, this pin acting as aguide. Aspiral slot 12 is made around the sleeve 6, and into this slot enters a part of a pin or screw 13, which passes through the tubular sleeve 5. Suitable connection being made with the lower end of the rod or sleeve 6 and the latter being pulled downward will move in a straight line by reason of the guiding-pin 11; but the spiral groove 12 around this sleeve acting upon the pin 13 will cause the latter to move around in the segment of a circle and carry with it the sleeve 5 and the turning-rod 7, thus turning the leaf. The length and curvature of the spiral groove are such that an easy pull upon the rod 6 will cause the groove to act upon the pin 13 and turn it as far as is necessary to turn the leaf, which would be substantially a half-revolution. In order to hold the rod 6 normally in its highest position and with the loose leaf lying upon the right side of the page, I employ a spring or elastic connection 14:, having one end attached to some fixed part carried by the plate A or its stationary attachments, and the other end is connected with a hook or attachment projecting from the lower end of the spirally-grooved rod 6. Thus the rod will be normally held up in the position just described. The pull upon the rod may very conveniently be effected by means of a slender wire, as at 15, connected with a pedal-lever, as at 16, so that the leaf may be turned by pressing upon this lever with the feet. In order to prevent the return of the leaf by reason of the elastic spring pulling upon it, I have shown the spiral groove or channel made with a little offset or depression at the upperend, as shown at 17, into which the tip of the pin 13 will drop when the rod 6 has been pulled down sufliciently to half turn the leaf. This depression is only sufficient so that the weight of the parts will prevent its returning; but by a touch upon the outer end of the pin 13 or some part projecting from the sleeve 5 the pin will be released from this holding-offset, and then the pull of the elastic spring will cause the return of the rod 6, and the reverse action of the spiral groove will turn the leaf back to its normal position, so that if music is to be played over again the leaf can be returned to its normal position by a slight touch.

Having thus described my invention, what I claim, and desire to secure by Letters Pat ent, is

1. A music-leaf turner comprising a rod and a hollow extension at the lower end thereof, a support and means by which it is secured to the music-rack, clamps on the rod for holding the inner edge of the music-sheet, a yokesupport in which the lower end of the hollow extension is journaled, a rod guided inthe hollow extension and having a spiral groove, a pin in the hollow extension fitting said groove, and means for moving the grooved rod longitudinally.

2. A music-leaf turner comprising a support adapted to be fixed to the music-rack, a

hollow sleeve having one end journaled and turnable in the upper part of said support, said sleeve having an extension-rod and clamps by which the loose leaf is carried, a yoke, a rod extending into the sleeve and slidable through the yoke in line with the support of the sleeve, said rod having a straight slot and a guide-pin passing through the yoke, and entering the slot, a spiral slot formed around the rod, a pin extending through the outer sleeve and entering said slot, means for pulling the rod downward whereby the spiral slot acts to turn the sleeve and the leaf, and a returning-spring connecting with the rod.

3. In a music-leaf turner, a support, means for fixing it to the music-rack, a hollow sleeve journaled in the support having a rod and clamps adapted to engage the inner edge of the music-leaf, a guided and slidable rod entering the lower end of the sleeve and having a spiral groove made around it, a pin extending through the sleeve and entering said groove, means for pulling the rod whereby the groove acts upon the pin to turn the sleeve and the leaf carried thereby, a spring acting to return the red when the pull has been released and an offset in the upper end of the spiral slot into which the turning-pin falls after the sleeve has been turned, said offset preventing the spring from returning the leaf until disengaged.

I. In a music-leaf turner, a clamp or support adapted to be fixed to the music-rack, a sleeve journaled and turnable in said support having an extension-rod and clamps to which the music-leaf is secured, a rod guided and slidable in the lower end of the sleeve having a spiral slot made around it, a pin passing through the sleeve with its inner end engaging the spiral slot, at foot-lever and connection between said lever and the lower end of the spirally-slotted rod whereby the rod may be pulled and the sleeve and leaf carried thereby turned, a spring connected with the rod and acting to return it when pressure upon the foot-lever is released, and an offset in the upper end of the spiral groove into which the turning-pin falls and by which the return action of the spring is prevented.

In testil'nony whereof I have hereunto set my hand in presence of two subscribing witnesses.

FRANKLIN B. MCNAMARA.
