GEORGE PEDLER, OF CHICAGO, ILLINOIS.

REED-ORGAN ACTION.

To all whom it may concern:

Be it known that I, GEORGE PEDLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Reed-Organ Actions, of which the following is a s ecification.

This invention re ates to organs and relates more particularly to reed organ actions. In certain types of organs of this class, as heretofore constructed, wherein a plurality of sets of reeds are employed on a common board and arranged to draw their air supply through a single channel, there is serious objection resulting not only from the noise due to features of construction, but from wind-robbing, so that the operation of the organ is seriously, aifected, since the small reeds do not receive their proper quantity of air.

The present invention has for its principal object to provide a reed action for organs so designed as to overcome the objections above set forth by separating the sets of reeds so that each has an independent air chamber that communicates with the wind chest.

A further object of the invention is to provide a reed organ in which the air inlet valves are arranged at the outside of the reed cells and the stop valves are arranged between the individual air chambers and wind chest. I

A still further object of the invention is to provide a simple, inexpensive and substantial mechanism for operating the inlet valves, one or both valves being adjustable so as to effect their proper closing.

Another object of the invention is to improve and simplify the construction and operation of apparatus of the character referred to so as to be comparatively inexpensive and easy to manufacture, composed of few parts compactly arranged, and eflicient and reliable in operation.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be' more fully described ereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustratesone of the embodiments of the invention, Figure 1 is a transverse sectional view of a lower reed action of an organ.- Fig. 2 is a similar view of an upper reed action.

Specification of Letters Patent.

Application filed April 3, 1907.

Patented July 14, 1908.

Serial No. 366,188.

Similar reference characters are employed to designate similar parts throughout the several views.

Referring to the drawings, and more particularly to Fig. 1, 1 designates the foundation board which is of suitable construction and arranged to form the bottom of the wind chest 2, the top plate 3 thereof being provided with air ports 4 arranged in sets to correspond to the sets of reeds, there being stop valves 5 for controlling the ports. The ports 4 communicate with the separate air chambers 6 that are formed by the reedboard 7 at the top, a longitudinal partition 8 and longitudinal strips 9 at the sides, and plate 3 at the bottom. Each reedboard has a set of cells 10 to accommodate a reed 11 in the usual manner. The outer longitudinal edges of the reedboards 7 are beveled to form seats 12 for the air inlet valves 13 that control the admission of air to their respective reedcells. Corresponding valves 13 on each set of reeds are mounted on separate levers 14 arranged to abut at their inner ends and dis posed in operative relation to the tracker pin 15 depending from the adjacent organ key 16. The keys 16 are mounted in the usual manner on the key frame 17, and disposed under the key frame is a member 18 through which the tracker pin 15 extends and interposed between each lever 14 and the member 18 is a helical compression spring 19 that operates through its lever to keep the inlet valve closed. Each lever has a rod 20 to which its air inlet valve is directly attached, the rod passing through a projection 21 and adjustably clamped thereto by a set screw 22. By this means, the valves can be adjusted with great accuracy. The inner ends of the levers are in engagement with a collar 23 on the tracker pin, and through the collar the tracker pin operates the levers to open the valves.

In operation, the airinlet valves are opened by depressing the organ keys 16, whereupon air is sucked by the bellows through the reed cells, reeds, air chambers 6, valve controlled ports 4, and wind chest 2, the valves being operated in any suitable manner. It will be noted that since the chambers 6 are rendered entirely independent by the partition 8, there is no danger of air robbing between the sets of reeds, each reed receiving its full amount of air since the suction through one air chamber 6 is equal to that through the other chamber. I

In the upper reed action shown in Fig. 2,

which is adapted for use in an organ having two actions, one of which is above and the other below the keyboard, thefeatures of contrsuction are for the most part similar to the action already described, except as to those parts that are altered to suit the location of the action in the organ. The bar 26 moves bodily with the pin 25 to which it is rigidly secured. Extending longitudinally of the center of the action is a channel 24 through which extend the vertical tracker pin 25 actuating the bar 26 that takes the place of I the levers 14 in the previous construction, and on the ends 01 each bar are rods 27, to

I which the air inlet valves 13 are adjustably to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention,

together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the app aratus shown is merely illustrative and that such changes may be made when desired, as are within the scope of the claims.

Having thus described the invention, what I claim is 1. In an apparatus of the class described, the combination of a pair of reed-boards hav ing cells, air chambers arranged to supply air to the cells, a wind chest common to the air chambers, valve-controlled ports between the air chambers and wind chest, air-controlling valves at the outer ends of the cells, movable horizontal members disposed over the reed-boards, rods on the members, said valves being adjustably mounted on the rods, and actuating means for the members whereby the valves of corresponding cells of the reed-boards are open and closed simultaneously.

2. In an apparatus of the class described, the combination of a wind chest, a pair of reed-boards having cells, independent air chambers for supplying the cells of each reed board, stop valves between the wind chest and air chambers, inclined seats at the outer ends of the cells, levers mounted on the reed-boards and having their inner ends presented to each other, a s ring operating on each lever, valves adj usta l mounted on the levers andheld closed by t e springs, and a tracker pin disposed between and engaging the meeting ends of the levers for simultaneously tilting the same.

3. In an apparatus of the class described, the combination of reed-boards provided with cells, valve seats at the outer ends of the cells, levers disposed over the reedboards, rods on the levers of round cross-section, valves adjustably mounted on the rods, means acting on the levers for maintaining the valves closed, and a tracker pin for operating a plurality of levers simultaneously.

4. In an apparatus of the class described, the combination of reed-boards each having a set of cells, reeds in the cells, inlet valves for controlling the supply of air to the cells, levers mounted on the reed-boards and car rying the valves, springs operating on the levers to hold the valves seated, keys for actuating the levers, and adjustable means for setting the valves on the levers so as to firmly seat.

5. In an apparatus of the class described, the combination of a pair of reed-boards hav ing cells, valve seats at the outer ends of the cells, a pair of levers, valves adjustably mounted on the levers for engaging the said seats, a stationary abutment, springs bearing on the abutment and levers for holding the valves closed, and a single tracker pin engaging the levers to actuate the same against the tension of the springs for opening the valves simultaneously.

6. In an apparatus of the class described, the combination of separate reed-boards having cells, valve seats at the outer ends of the cells, rods of round crosssection, valves adjustably mounted on the rods, means for clamping the valves on the rods, a single tracker pin, means between the tracker pin and rods for opening the valves simultaneously, and an elastic means operating to hold the valves closed and to return the tracker pin to normal position.

In testimony whereof, I affix my signature in presence of two witnesses.
