SPECIFICATION forming part of Letters Patent No. 587,053, dated July 27', 1897'.

Application filed April 12, 1897. fierial No. 631,769. (No model.)

To all whom it may concern.-

Be it known that I, Josnrrr Benson, a citizen of the Dominion of Canada, residing at Jackman, in the county of Somerset and State of Maine, have invented certain new and useful Improvements in Leaf-Turners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto 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 1 is afrontview of the leaf-turner. Fig. 2 is a side view of the same. Fig. 3 is a cross-section taken on the line aw in Fig. 2. Fig. 4 is a detail side view of the means for keeping the cords taut. Fig. 5 is a detail plan View of one of the turningarms. Fig; 6 is a front view of one of the clips. Fig. '7 is a side view of oneof the pedals and its connections.

A is a base, and B is a hollow vertical post secured to the base.

C is a vertical post which is slidable inside the post B.

I) is a desk for holding the music or book, and d are spring-actuated clips for holding the music in position. The clips d are attached to the desk by curved arms (1.

E is a pi vot-pin secured to the middle of the lower part of the desk, and e are arms pivoted on the said pin and having spring-actuated clips 8 at theirends for engaging with the leaves to be turned.

A are pedals pivoted on pins a, carried by the base A. Cords b or other equivalent flexible connections are attached to the pedals A and to the opposite ends of the arms 6 from the clips 6. Each arm 0 is connected to two pedals. The cords b are connected to the arms c by pivoted links (1 upon opposite sides of the arm, and the links d are crossed and the cords Z) are led away in opposite di rections and pass over guide-pulleys 61, carried by the desk, so that the arms may be moved back and forth by depressing the two pedals alternately.

The cords pass over the pulleys D, and E are adj listing-screws for connecting the lower ends of the cords to the pedals. hen a nonextensible post is used, the cords may pass direct from the pulleys d to the pulleys D.

In order that the height of the desk may be adjusted and the cords b be kept taut, toothed racks F are provided on the post B, and similar racks f are provided on the post 0. G are toothed pinions which gear into each opposed pair of racks F and f.

The pinions G are mounted on a shaft g, and g are guide-pulleys journaled on the shaft g. The cords b are looped under the pulleys g and over guide-pulleys h, journaled at the upper part of the post 13.

II are plates secured to the post B for the backs of the racks f to bear against.

The post 0 is moved up and down by hand, and the pinions G are moved up and down by the racks, so that the cords Z) are always kept taut.

A fastening device is provided for holding the post 0 after its position has been adjusted.

This fastening device preferably consists of an eccentric II, journaled in brackets which are secured to the top portion of the post B. The eccentric is arranged to bear against the post 0, and it is provided with a lever 2' for operating it.

The leaves of the music on the desk are placed in engagement with the clips e and are turned over by depressing the pedals.

hat I claim is-- 1. In a leaf-turner, the combination, with a base, a post secured thereto, apost slidable in the aforesaid post, and a desk secured to the said slidable post; of arms pivoted to the said desk, pedals pivoted to the said base, cords connected to the said arms and pedals, guide-pulleys for the cords supported by the said desk, post and base, and slidable guidepulleys operating automatically to keep the said cords taut when the slidable post is moved vertically, substantially as set forth.

2. In a leaf-turner, the combination, with a stationary hollow post B provided with toothed racks, of a slidable post 0 also pro- Yided with toothed racks, plates guiding the post C in the post B, toothed pinions gearing into the racks on the posts B and O, a shaft carried by the said pinions, guide-pulleys g joui'naled on the said shaft, guide-pulleys it carried by the upper part of the post 13, lea-fturning arms supported by the post 0, and operating-cords attached to the said arms and
