OCTAVE-COUPLER FOR FOLDING KEYBOARDS FOR ORGANS.

SPECIFICATION forming part of Letters Patent No. 469,699, dated March 1, 1892.

Application filed November 23, 1891. Serial No. 412,741. (No model.)

To ctZZ whom it may concern:

Be it known that I, FREDERICK W. HEDGE- LAND, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Oetave-Couplers for Folding Keyboards for Organs, of which the following is a specification.

I have heretofore devised a keyboard for I.) organs adapted to fold up and into the case of the instrument; and my present invention relates to the con1bination,with such akeyboard, of an octave-coupler adapted to told with the keyboard and which requires no disconnecting preparatory to the folding of the board.

I have illustrated my present invention in the accompanying drawings, wherein- Figure l is a vertical section of that portion of the organ to which my invention relates, showing the keyboard and coupler lowered for use, and Fig. 2 a like section, show ing the parts folded up.

In the drawings, A represents one of the keys, B the front, and O the bottom, of the 2 5 keyboard, which is hinged to the case of the instrument at 0. Above the keys is the stopboard D, in which are the draw-stops D, (only one being shown,) provided with pulls or knobs d.

av is the key-rail, and a the support for the rear end of the keys, and Z) the rail limiting the dip of the keys. All these parts fold up and open simultaneously, though the stopboard turns upon a center in line with the 5 pivot of the joint d in the stop D.

The dotted lines, Fig. 1, show the relative movements of the key and stop boards.

E is a section of the case-front hinged at e and adapted to swing up and inward and 40 make room for the stop-board, as shown at Fig. 2.

F is a guard applied to the stop-board for operating the section E and preventing interference between it and the stops.

M is the locking-board engaging with the front of the stop-board.

The parts above described I do not claim in this application, as the present invention relates to the coupler which will now be described.

G is the usual board supporting the series of octave-couplers II, only one of the latter being illustrated. Said board swrngsfreely upon a leather hinge '1', connecting it with the supportinga'ail I, and is raised and lowered to throw the couplers into or out of operative position by a rocking lever having bent-up arms J, this being the usual construction. One end of each of the couplers II pro ects over and operates a lever K, supported by and pivoted upon a rail L, extending from end to end of the manual, so as to support the entire series of levers K, there being one of these levers for each coupler. The farther end of each lever K extends under and operates a sticker N, each of which passes through and is supported in an opening in the rear end of one of the keys A, and under the horizontal arm of the elbow-lever O, which operates the tracker o of the same key. The rear ends of the series of levers K are sustained upon a piece of webbing I, stretched across the manual under the series of levers. Iuse webbing for this purpose, as it 1s entirely noiseless, and is cheap and easily applied and takes up less room than awood rail. The couplers are actuated by the depending buffers 7L, attached to the keys.

This being the construction, the coupling devices operate as follows: Then the octave of the key shown is struck, the coupler II is actuated, and through it a movement is given to the lever K, lifting the sticker N and sounding the note represented by the key shown. This is done without any movement being imparted to the key itself. At the same time, when the key shown is struck, the only part of the devices connecting the coupler with the elbow-lever O which is moved is the sticker N .fQWhen the keyboard is folded, the key and sticker move away from the elbow-lever, aslthey are unattached to said 1ever, and they at once resume operative position therewith when the keyboard is again lowered. No disconnecting of the key or coupler from the action is required previous to folding the keyboard, nor is any attachment necessary upon unfolding it.

I claim- 1. The combination, with the keys of a folding keyboard, the octave-couplers, and the action operated by the keys and couplers, of

levers K and stickers N, substantially as set forth. I

2. The combination, with the keys of a folding keyboard, of octave-couplers H, pivoted levers K, operated by the couplers, stickers N, operated by said levers, and the action actuated by said keys and stickers, substantially as set forth.

8. The combination, with the keys of a folding keyboard, of stickers N, loosely supported in the rear end of the keys, octave-couplers for sounding" the action of the several keys, and means for carrying motion from said couplers to said stickers, substantially as set forth.

4. The combination, with the keys of a folding keyboard, of the octave-couplers, and connections carrying motion from the couplers to the actions of the several keys, said connections being unattached to the actions, substantially as set forth.

5. The combination of the keys having no attachment to the action, and octave-couplers with connections for carrying motion from the couplers to the action, but unattached to the latter, and a folding keyboard carrying said keys, couplers, and connections, substantially as set forth.

6. The combination, with the levers K, of the webbing B, substantially as set forth.

7. The combination, with the keys A and their several actions, of the series of couplers H, the series of pivoted levers K, the series of stickers N, and a support, such as P, for said levers K, substantially as set forth.

8. The combination of the folding keyboard and the keys and couplers supported therein, and the motion-receiving part of the several actions located in position to be operated by either the keys or the couplers, but unattached to either of them, substantially as set forth.
