IIWPRQVEIVEENT OF vALVE-ARRANGEIVEENT FOR. ORG-ANS.

The Schedule referred to in these Letters Patent and making parto! the sama.

Beit known that I, MORITZ BAUMGARTEN, J r., of New Haven, in the county of New Haven, and State of Connecticut, have invented a new Improvement in Valve-Arrangement for Organs; and I do hereby declare the following, when taken in connection with the accompanying drawing, and the letters. of reference marked thereon, to be afull, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents a sectional view of -the wind-chest, with the valves for the three .sets of pipes.

This invention relatesto -an improvement inthe arrangement of the valves to open communication rom'the wind-chest to the pipes; the object being to render the closing of 'the pipes more positive and perfect than has heretofore. been done, as well as to materially lessen the cost of construction, the invention being au improvement upon a patent granted to me,

June l2, 1866; and this invention consists in fixing the several valves, one foreach chest, upon a single rod,

so that the movementof the said rod both opens and positively closes the valves, the rod passing through the opening communicating to the pipe, so that the valvesl may be easily adj usted on the rods to close their respective openings.

To enable others to construct my improvement, I will fully describe the same, as illustrated inthe accompanying drawing.

A is the upper plateof thewind-chests E F G, the said chests being formed by partitions H I K, and each ofthe chambers-communicating, through openings B C D, with its respective sets of pipes, as denoted, in

the drawing. Centrally through the openings which communicate directly to the chambers, I pass a rod, L,

upon which vis arranged a spring, M, so as to force the rod forward, and connected `with a correspondingkey on gthe key-board, so that the depression of the key forces the rod inward. On the said rod in each of the chests, are fixed the respective valves P R S, all adjusted so that, when the rod is free, the three valves will tightly close their respective openings. Upon the face of the valve, I attach a piece of kid, for packing,

of larger diameter. .than the face of the valve, so that if, from any cause or dsadjustment, the valve-blocks of one should not lie tightly against and so as to perfectly close the opening, the kid packing will by the wind be forced on to the partition, so as to make' the closing of the opening perfect. In each partition, at

'the perforation through which the rod passes, as fat a,'I tix a suitable packing around the rod to prevent the passage of the wind from one chest to another, and

' and greatlyreduced-in dimensions, and the expenseof construction consequently very greatlyreduced, all of which tendA to improve the instrument.

The rod is forced inward in the usual manner, and being so forced, opens all the valves upon the rod in as perfect manner as in my patent before referred to. The closing of the valves is by this construction rendered positive and perfect.

A thread may be out upon the rod, and the valves adjusted thereon, by being secured on to the rod, ora set-screw may be set into the valve on to the rod, so as to fix the valve in its proper position. These valves move directly and bodily from the opening, which admits a free passage of wind entirely around the valve,
