WILLIAM JACKSON, OF ALBANY, NEW YORK, ASSIGNOR TO HIMSELF AND HENRY G. WILKINS. OF SAME PLACE.

Letters Patent No. 102,822, dated May 10, 1870.

IMPROVEMENT IN CHURCH-ORGANS The Schedule referred to in these Letters Patent and making part of the same.

' panying drawings forming a part of this specification,

in which Figure 1 represents a perspective view of an orgar, with improvements.

Fignre 2 is a longitudinal cross-section through airchamber, and supplementary air-chamber attached.

Figure 3 is a cross-section of the same, viewed from the front.

Figure 4 is a side view of stops, draw-rods, \vith'the composition bar and theirlevers attached.

Figure 5 is an end view of the same.

Figure 6 is a longitudinal moss-section of a pipe.

Figure 7 is a view, from back, of the apparatus for operating the bellows.

- To secure a constant flow of air from the bellows into. the air-chambers, I operate the bellows by a number of levers and bars, which are worked by a crank formed on the shaft of a fly-wheel, which fly-wheel is turned by a handle, and operates the several bellows in such a way as will bring up some one or more of the bellows while the others are going down.

I also attach to the draw stop-rods one extra arm each, and thesaid extra arms pass between what I call composition bars, which are fitted together in pairs, and are connected by T-headed levers at either end, and may be operated by pneumatic valves or the knees or feet of the operator, who can, by them, work quickly the stops, and throw them in or out at will.

To enable others skilled in the art to make and use my invention, I will proceed to describe it in reference to the accompanying drawings and letters of reference marked thereon, the. same letters referring 'to like parts. I

AA is any suitable frz'nne-work for an organ to be constructed.

Upon the lower platform p, figs. 1 and 7, is placed the usual air-chamber B; This air-chamber B is fed oy two or more bellows, C G, figs. 1, 2, 3, and 7, operated as follows:

A fly-wheel, W; furnished with a crank-shaft, a, supported by suitable standards, 3 s, operates a carrying block, I). To each end of the said carrying-block are attached the bars 0 c, which connect with and operate the-angle-levers (Z d, supported by the standards s s. Connected with one of the arms of the levers d (l are the connecting-bars e e, which. are attached to the lifting irons of the feeders or bellows c c. If

three feeding-bellows are to be used, I connect with the carrying-block 71 a third connecting-bar, c, the lower end of which is attached to the lifting-iron of the said third bellows C, and, when the fiy-wheei \V is revolved, the crank a carries the carrying-block b back and forth, and up and down, thereby working the feedingbellows 0-0 G alternately, one feeder being full, one empty, and the other partially/filled.

'lo readily operate the stops P and slides r the raw-rods k k are furnished with extra arms in on, and the said arms in operate the composition bars a n, which are coupled in pairs, as shown in figs. 4 and 5, one. bar of each pair being placed above and one below. Attached to the heads of the composition bars a n are the T-headed levers 0, which may be operated by pneumatic valves, or by the knees or feet of the operator. The heads of the composition bars may be used on either end with the T-levers. Pins t t are placed in the upper and lower bars of the composition bars at n, which operate the draw stop-irons k it upon any combination of the stops before agreed upon.

Having thus described my invention, 7

What I claim. and desire to secure by Letters Patent, is-

1. In combination 'with the bellows O O of a churchorgan, the fly-wheel- W, with the crank a, bars 0 c, levers (Z d, and connecting bar e c, constructed and em ranged substantially as described and for the purpose specified.

2. The extra arms in of the draw stop-irons k, in combination with the composition-bars n a and their pins t, and the T-headed lever o, as and for the purpose set forth and described.
