MUSlC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 397,241, dated February 5, 1889.

Application filed June 13, 1888. Serial No, 276,926. No model.)

To all 207mm it may concern:

' illustrated in Figsland it.

Be it known that I, FRANK H. Loucutiix, of Syracuse, in the county of Onondaga and 1 State of New York, have invented a new and 1 lm )roved Music-Leaf Turner of which the i following is a full, clear, and exact description.

My invention relates to an improvement in music-leaf turners, and has for its objectto provide a simple, cheap, and effective device capable of ready attachment to and detachment from a musical instrument or musicstand, and whereby the leaves of sheet-music 3 may be independently turned in an expeditions and convenient manner.

The invention consists in the construction and combination. of the several parts as will be hereinafter fully set-forth, and pointed out in the claims.

if are made in the topand base plate in which a latch-rod, F, is held to reciprocate. lfpon the forward edge of the said latch a series of lugs. ora lengthy lug, f", is secured or cast intogral tlun'ewith, one lug being provided for each drum used, which lugs are purposed, when the drums are revolved and the spring contained therein contracted, to enter the slots P of the drums and retain the same against the g tension of the springs.

Reference is to be had to the accompanying drawings, forming a part of this s 'iecitimtiou, in which similar letters of reference indicate corresponding parts in all the figures.

7 Figure l is a front elevation of the device applied to a piano. Fig. 2 is a rear view of the same. Fig. 3 is a plan view. Fig. at is a central vertical section on line .r of Fig.

j to thccombim-d height of thc drums.

When a single lug is employed, as shown, it. is of a length equal In the 1 rear edge of the latch a series of notches/"' Fig. 5 is a transverse vertical section on line i y y of Fig 3; and Fig. 6 is a plan view of a drum, adapted to carry the leaf-holders, having the top removed.

In carrying out the invention lLlJQlJZISE-PliltG A is provided with a dovetail rib, A, upon the under face, and a second or top plate, B, is supported a distance above the base-plate, parallel therewith, by studs or posts Z1 Z).

A vertical standard, D, is secured, respectively, to the top and base plates in any approved manner, being preferably stepped in said plates, as best shown in Fig. i. In the upper end of the standard D a perpendicular recess is produced, in which recess the lower i end of a cylindrical rod, D, introduced and retained in rigid position by a set-screw, (7, passing through the standard to an engageother well-known t't-istening devices.

A series of hollow drums, E, is held to turn upon the rod I), each of which drums contains a coiled spring, E, one end of which spring is secured to the rod, the other end being attached to the inner wall of the drum, as best is produced, preferably corresponding in number to the drums, the uppermost; of which notches is preferably located below the hori zontal plane of the lowermost end of the lugf.

A pintle, H, is transversely journalcd in the post Z) beneath the top plate, and upon the rear end of said pintle an elbow-lever, H, is rigidly fastened, the extremity of the horizontal member of the lever being adapted to engage the notches in the latch, as best shown in Fig. 2. The said elbow triplever is held in contact with the latch byaspring, 72, coiled upon the pintle, having a bearing against the front side of the post and likewise against a stop formed upon the forward extremity of the pintle, as clearly shown in Fig. 5. The said horizontal member-of the elbow-lever H is held in such position by a coilspring, K, secured to the inner side of the vertical member, at or near the extremity, and also to the opposite end of the base-plate, as shown in Fig. 2. The movement of the elbowlever is limited by a spur, 7;, projected from the botment with the rod, or through the medium of i tom of the vertical member, which spur travels in a slot, 7.", in the base-plate.

To each of the several barrels a longitudimilly-slotted arm, M, is secured, provided at each end with. upwardly-projccting slotted pins or tines n1, which arms and tines are purposed to clamp the several sheets of the music at the bottom of the page, as illustrated in dotted lines, Fig.1.

The pins or tines and likewise the arms may be of any desired length.

To attach the device to a musical instrunient-for instance, a pianoa block, S, provided with a dovetail groove, S, in the upper face, is permanently attached to the base of the swinging restor to the front board immediately in advance of the rest. The block S is likewise provided with a slot, S adapted to receive the latch of the device. It will thus be observed that by sliding the dovetail rib upon the base of the device into the similar groove of the block the turner expeditiously and conveniently applied.

The elbow-lever is actuated by a pedal, N, pivoted in any approved manner to the lyre, which pedal is connected by a cord, N, with the vertical member of the elbow-lever, as best shown in Fig. i. The cord N passes over pulleys 72, suit-ably placed, and is detaehably secured to the said lever.

In operation the arms M are bunched, as illustrated in Fig. 3, whereby the several slots 6 in the drums are brought in vertical alignment, and the latch, is drawn upward until the lug f thereon engages each of the said slots, as shown in Fig. i, and the leaves of the music to be turned are inserted in said arms.

Upon pressing upon the lever I the elbowlever bears upon the lowernotclnf of the latch and depresses the same to such an eX- tent that the upper barrel is disengaged from the lug, whereupon the spring E, acting, revolves the released barrel, causing the arm. attached thereto to make about a halfrevolution, the same being stopped by contact with a pin, R, projected upwardly from the post I), as best shown in Fig. 1. By pressing the pedal again the next drum is revolved, and so on until the last leaf is turned.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a base, a springactuated elbow-lever pivoted to the same, and an upwardly-enter]ding vertical post secured to the upper surface, of a series of spring-actuated drums revolving upon said post provided with a diametrical peripheral slot, arms horizontally projected from said drum, anda perpendicularlatch provided with an offset upon one edge and notches in the opposite edge, all combined to operate substantially as shown and described.

2. The combination,with a base, a springactuated elbow-lever pivoted to the same, and an upwardly-extending vertical post or bar, of. a series of spring-actuated drums revolving upon said post provided with a diametrical peripheral slot, slitted arms horizontally projected from the drums, a perpendicular latch provided with an offset upon one edge and notches in the opposite edge, afoot-lever, and connections between said foot-lever and elbow-lever, substantially as shown and described.

3. The combination, with a supportingblock provided with a dovetail groove, a base provided with a dovetail rib adapted to enter said groove, a spring-actuated elbow-lever pivoted upon said base, and a vertical post or bar extending upward from the same, of a series of spring-actuated drums revolving upon said post provided with a diametrical peripheral slot, slitted arms horizontally projected from the drums, a perpendicular latch provided with an offset upon one edge and notches'in the opposite edge, a stop-pin secured upon the base, a foot-lever, and connections between said foot-lever and elbowlever, all combined to operate substantially as set forth.
