IMPROVEMENT IN ORGAN-BELLOWS.

TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Y Be Ait known that I, ELIHU H. THOMAS, Jr., of Brattleboro, in the connty of Windham, and State of Vermont, have invented a new and useful Improvement in the Blowing Mechanism of Reed or other Organs and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a front elevation of a pair of organ-bellows provided with my invention.

Figure 2 is an inner end view of one of the bellows, and the mechanism for operating it.

This invention is applicable to what are termed upright bellows. Most of the modes heretofore employed for operating the movable or 'pumpingboard of' a bellows of' an organ are more or less complicated, 'and liable to become deranged, or to easily get out of order, and cause more or less noise while in action. My improvement issimple in construction, very still and eicient in its operation, and may be thus described:

In the drawings, A A are a pairoi` upright bellows, of which b are the movable or pumping-boards, such bellows being arranged within an organ-case, B,- in the usual manner, as representedin the drawings. Near the inner edge of each of the said'movable beards b is a sector, e, which at its vertex is connected to the organi? frame by a hinge,h. A rope or strap, d, fastened to a pin, p, projecting from the upper part of the inner edge of the board b, passes around, and may be fastened in one or more places to the arc of the sector, and thence extends downward and is fastened to one of two pedals, e e. To each board b and the organ-frame'a spring,f, is applied close to the sector, such spring being for the purposeot` forcing forward the board after each retraction of it by the pedal, the strap, and the sector. By pressing the pedal downward, the sector will be moved or turned on its hinge, and the strap will draw the board b backward, its return to place being subsequently e'ected by the spring. The sector throughout its vibrations plays with very slight friction and movement at its hinge, and thus is very s till and effective in its operation.

What I claim' as my invention, isn p The combination and arrangement of the sector and its hinge with the strap, the pedal, the bellows,nnd its operative spring, thewhole being substantially as specified.
