tlllTTED STATES PATENT FRANK E. RODLIFF, OF BURLINGTON, VERMONT.

LEAF-TURNER.

Application filed December 6, 1913.

To all whom it may concern Be it known that I, FRANK E. Ronnrrr, a citizen of the United States, residing at Burlington, in the county of Chittenden and State of Vermont, have invented certain new and useful Improvements in Leaf- Turners, of which the following is a speciiication.

This invention relates to leaf turners for turning sheet music, etc., and it comprises such a leaf turner having a back frame or support divided at its upper end and with one of the sections of this divided upper end offsetwith respect to the plane of the other, together with spring-actuated leaf-turner arms mounted on one of said sections and means for holding and releasing said arms in succession mounted on the other of said sections. It further comprises such a leaf turner provided with novel means for releasing the spring actuated leaf-turner arms in succession so that only one arm can be released at a time and the remaining arm or arms will be then released one only at a time until all are released.

It also comprises certain novel features of construction and arrangem nts of parts, all as more fully hereinafter set forth and as claimed.

In the accompanying drawings is illus trated one embodiment of the present invention, and the invention will be described more particularly in connection therewith and with reference thereto, it being understood however, that the invention is illustrated by, but is not limited to, the specific structure of this embodiment.

In the accompanying drawings :Figure 1 is a top plan of the leaf turner; Fig. 2 is a side elevation of the leaf turner; Fig. 3 is a front elevation of the leaf turner; Fig. 4 is a detail of the spring actuated arms and their supports and actuating springs; Fig. 5

is a side elevation, similar to Fig. 2, of the top of the leaf turner, showing the parts in position for turning the music; and Fig. 6 is a section on the line 11 of Fig. 3.

I will now proceed to describe my invention more in detail with reference to these figures of the drawing, illustrative thereof.

This leaf turner, as illustrated, comprises a back frame or support 1 bifurcated or slotted at its upper end at 2 to form two sections 3 and 4-. The section 3 is offset at 5 so that its plane is in front of the plane of the body 1 and section 4. At its lower end,

the body or frame 1 is bent forwardly at 6 and then back again at 7 and is provided with the bearings 8 for the lever 22 and with a bolt 9 or other suitable attaching means for attaching the leaf turner to a piano or other musical instrument etc., it being understood that the specific structure of the attaching means can be varied without departing from the invention. Mounted on the front section 3 near the top of the leaf turner are the a "ms 10 and 11 for turning the leaves of music etc., these arms bemg of wire, wood, or other suitable material; and on these arms are clips 12 of any suitable or approved construction for holding the individual leaves. These clips 12 are shown as spring clips. The inner ends of the arms 10 and 11 are enlarged, as at 13, and formed with, or attached to, spindles 17, each arm and spindle being rotatably mounted upon, and supported by, the. said frame section 3. As shown, the arm and spindle are provided with upper and lower collars 16 and 14 which engage the divided collar or support 15 and thereby hold the arm and spindle in position. The divided collar 15 is attached to the section 8 in any suitable manner. The particular form of bearing, and means of holding and supporting the arms 10 and 11, are illustrated somewhat diagrammatically, and it will be understood that their specific structure can be varied, and other suitable or equivalent bearings or supports utilized. Surrounding the spindle 17 is a casing 19, suitably attached to the section 3, and between the spindle and casing is the coil spring 18, made up of a single coil or a plurality of coils. Near the inner ends of the arms 10 and 11 are enlargements 20 adapted to engage the forwardly extending projections 21 on the section 8, these projections being shown as formed integrally with the sections l, by bending the sheet metal or material thereof into the form shown.

Mounted in the bearing 8 is the operating lever 22, pivotally connected at 24 with the operating rod 23. This rod 23 is shown as guided by suitable lugs or guides 25 on the frame 1. At its upper end the rod 23 has an enlargement 27 terminating in a shoulder and beyond this enlargement an extension 26. It will be understood that the rod 23 and extension 26 are made either detachable or integral and that the relative size and length of these parts can be varied with which they form a part. Above the end of the specific structure of the leaf turner of the rod 26 is a trip cam or member 28 mounted in guides 29 and having a spring catch 34 on its lower end. To one side of the rod 26 is another trip member 31 mounted in'guides 32 and providedat its lower end with a spring catch 33. Mounted in the member 31 is the pin or pivot 35, and on the ends of this pivot are the arm 36 and the cam or member 30, the arm 36 and member 30being attached to the pivot 35 so as to rotate therewith and to the same extent. The spring catches 33 and 34- are similar in structure and are attached in any 'suitable'manner for example, by tenons 15 passing through openings inthe section 3 (not shown) to the members 31 and 28 respectively, as'by soldering, brazing, riveting etc.

It will be seen "that the offset section 3 carrying the arms 10 and 11 and their spring supports is arranged in front of the section' i carrying the spring catches 33 and 34 and their cooperating and actuating elements. Asa result, these elements are 10- 'cated back of the plane ofthe arm supports so that the arms can be swung to the right into a position parallel'to the back of the main support l, without interfering with the various elements mounted on the 1 section 4.

when more than two are used embodies the same'construction, with additional arms of the same construction and operation as the arm 11, and that these arms will be released in succession in the same manner that the arms 10 and 11 are released.

I'will now proceed to describe the opera tion of'the leaf turner illustrated, it being understood that the description of the operation'of the arm 11 is the same as that of other arms where a plurality of such arms are used, and that the provisions for holding and releasing the arm 11, and for preventing this release until the arm 10 has been first released, are the same where more than two arms are used. The arms 10 and 11 are swung to the right from the positions shown in Figs. 1 and 3 until they are engaged and heldbythe spring catches 34 and 33 respectively. The arm 10 engages the arm 36 and moves it back, as shown in 'Figfii, thereby swinging the cam or memberf30 out at'its lower end so that it cannot be engaged by the shoulder 27. Now when it'is' desired to turn one leaf the lever 22 is. depressed, thereby raising the rod 23 until its extension 26 engages the member 28 and raises it and the spring catch 34, thereby releasing the arm 10, which is swung to the left by the coil spring 18, this an carrying with it the leaf of music, etc, attached to it by the clips 12. Until the arm 10 is released the pivoted member 30 is held in the position shown in Fig. 5 so that the shoulder 27 cannot engage it; but on releasing the arm 10 the arm 36 is permitted to swing forward and the'member30 backward to the position shown in Fig. 2, so that it may be engaged by the shoulder 27. Now, when the end of the lever 22 is again depressed the shoulder 27 engages this member 30 and raises it together with the spring catch 33 and its guide member 31, thereby releasing the arm ll'and permitting its spring to swing it to the left into the position shown in Figs. 1 and 3. It will thus be seen that'only one arm can be released at a time, and that upon. releasing one arm the other can be released by again operating the'lever 22, and so on for as many arms as maybe provided.

From the preceding description it will be seen that the device is simple and reliable in construction and operation, and that the positive operation of the device and the successive operation of the armsand the sheets 1 frame arranged to engage and retain-said arms when swung intoengagement therewith, and to release; said arms in succession,

3. A leaf turner comprising a frame, leaf turner arms mounted one above another on the left hand side of said frame near its upper end and provided with springs for normally holding and swinging said arms to a position to the left of said frame and permitting swinging of the arms into a position to the right of said frame, a plurality of catches on the right hand side of said frame for engaging and retaining said arms when swung into engagement therewith and means for releasing said arms successively, said means comprising an operating rod, an upper guide member carrying a catch arranged to be operated by said rod, a lower guide member carrying a catch, a pivoted actuating member supported by said lower guide member arranged to be swung into or out of position to be engaged and operated by said operating rod, and a pivoted arm also mounted on said lower guide member and connected to said pivoted actuating member and arranged to be engaged by one of said leaf turner arms when held by the upper catch and to move said swinging member into inoperative position.

In testimony whereof, I affix my signature in the presence of witnesses.
