lili USlC-'i'URNER.

SPECIFICATION forming part of Letters Patent No. 590,432, dated September 21, 1897'.

Application iiled June I5, 1897. Serial No. 640,860. (No model.)

Be it known that I, WILLIAM JAMISON CURRY, a citizen of the Dominion of Canada, residing at Nanaimo, in the county of Nanaimo, Province of British Colu1nbia,Canada, have invented certain new and useful Improvements in Musicflurners; and I doliereby declare the following to be a full, clear, and

exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to leaf-turners; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a front view of the leaf-turner. Fig. 2 is a plan view of the same. Fig. 3 is a detail side view of one of the turning-rods. Fig. i is a detail view of the top portion of the rod D.

A is a desk which is supported in any approved manner.

B is a metallic plate provided with a central groove a and secured to the middle part of the desk7 and projecting therefrom so as to hold the fold of the book above the level of the desk.

Cisa rod which is passed between the leaves i of the book at the fold and which keeps the fold of the book clamped in the said groove a. The bottom end of the rod C is provided with an eye c', which engages with the head of a pin b, which slides in a hole in the desk.

B is a spring secured to the pin behind the desk and operating to press the rod toward the desk.

O' is a spring secured to the upper part of the desk and provided with a bent end portion c, with which the upper end portion of the rod C engages.

D is a rod which is slidable vertically in bearings d secured to the desk. The rod D is arranged behind the plate B, and d is a spring which is secured to the desk and which bears on the rod D. rlhe spring d prevents the rod D from either sliding up or down when it engages with a notch o in the said rod unless the rod is turned to the left. The pressure of the spring CZ prevents the rod from turning accidentally. "When the rod D is pushed up, its tapering upper end engages vented from turning while being iitted over the leaves to be turned by the pressure of the thumb on the pins s, which are screwed into A the lower end portions of the rods e, and which work in the slots s in the end portions of the arms E. The leaves of the book or piece of music to be turned are slipped between the forks of the rods e. Each arm E is provided with a thumb-piece e for operating it.

F is a cord of flexible material, such as catgut, which extends across all the turningrods e. The ends of the cord are secured to the desk by springs f. 'Ihe cord and springs hold the turning-rods pressed against the desk whether they are to the right or to the left of the rod D. The turning-arms are moved to the right or to the left by hand against the tension of the said springs and cord.

G are ledges secured to the lower part of the desk for thebook to rest against. Each ledge has a long notch g in its front edge.

II are spring-pressed clips which work in cross-notches 7i, in the ledges G. Each clip has a stein I, which is slidable and revoluble in a hole in the desk at the bottom of the cross-notch, and i' is a spring secured to the said stein behind the desk and operating to press the clip toward the desk. Each clip has a thumb-piece j at its lower part for manipulating it. The clip can be turnedaround so that it rests in the notch g, as shown at the right hand in Fig. l., after being pulled forward against the tension of the spring. IVhen in this position, the book can be placed on the desk, and the clip can then be turned around to the position shown atthe left hand in Fig. l, so that it engages with the cross-notch 7i and bears against the cover of the book and those leaves which are not wanted to be turned. Y.

The clipII can be pulled forward against the tension of the spring and turned so that it rests on the edge of the ledge G and projects over the book. In this position the clip IOO keeps the music open and yet leaves a eonsiderable space between the clip and the desk, which Vis sometimes desirable.

The object in making the rod I) slidable is to enable the forked turni11grods to be slid into and out et' engagement with the leaves to be turned.

`What I claim isl. In a leaturner, the combination, with a desk provided at its lower part with a long notch g and a cross-notch 7i, of a clip provided with a stein which is journaled in a hole at the bottoni el the said erossnotch, and a spring secured to the said stein behind the desk, and permitting the elip to engage with either notch, substantially as set forth.

2. In a leaf-turner, the Combination, with a desk, ot' a eurved plate secured to the niiddie of the desk and projecting above its surface, a rod C provided with an eye at its lower end, a pin engaging with the said eye and slidable in a hole in the desk, a spring seeured to the pin behind the desk, and a spring secured to the upper part ot the desk and provided with a bent end portion for the upper portion of the rod C to migagewilh, sul stantially as set lforth.

3. ln a leaf-turner, the combination, with a desk provided with bearings d, of a rod slida-hlc vertically in the said bemings, a g

spring secured to the desk and pressing on the rod so that it is hindered Aironi. sliding, and turning-arms journaled on the said rod, substantially as set forth.

i. In a leaf-turner, the eonibinatimi, with a desk, and a rertieal rod supported thereby; of turning-arms pivoted on the said rod and provided with forked turn ing-rods projecting vertically from their end portions, a Iicxible eord extending across the said turning-rods, and springs connecting the ends of the said eord with the desk, substantially as set forth. In testimony whereof I al'lixv luy signature in presence of two witnesses.
