Speocation of Letters Patent.
A invented certain new and useful Improvements in Air-Chests, of which the following' is a specification.
This invention relatesto air-chests, theobject of the invention being to provide a device of this character having means associated therewith, which is positive and certain in action and by which the supply of air from a pump or its equivalent to such chest can be effectively and precisely controlled.
-While an vair-chest involving the invention can be employed with advantage 1n many different connections, it is of especial utility when incorporated in or forming part of a pipe organ.
In the drawings accompanying and forming part of the present speciicationrwe have shown in detail one of the several convenient forms of embodyment of the invention which to enable those skilled in the art to practice `the same will be vset forth fully in the following description. We do not restrict ourselves to this disclosure; we
may depart therefrom in several respects Vwithin the scope ofthe invention defined by the claims following said description.
Referring to said drawings: Figure 1 1s a vertical sectional view of an air-chest and coperating elements involving our mvention, showing the pump as cut off from the air-chest. Fig.- 2 is a ar view with the pump supplying the air-chest. I
Like characters refer to like parts 1n both views. y
The numeral 2 denotes an archest, 3 a puin and 4 a duct connecting the pump with the air-chest, all suitable for our purpose. Inclosed by the duct or supply pipe .4 is a valve 5 shown as being of buttery type. In Fig. 1 the valve is closed so as to cut off communication between the pump 3 and the air-chest 2. In Fig. 2 the valve 1s shown open so as to put the pump into com. munication with said air-chest and 1n the In said air-chest 2 is mounted a pneumatically-governed member as the bellows 6,the chest having ports 7 and 8 opening from the atmosphere into the interior of the bellows 6. Between the chest 2 and the movable board 9 of the bellows and inclosed by the latter is a spring device as 10 which tends constantly to -expand the bellows 6 or to move the board or body -9 thereof inward. To the body or board 9 of the bellows s connected the stem or shank 11of the valve 12, this shank or stem being fastened to the inner face of the board or body 9 within the tube 13 extending into the chest 2, the other end of said tube having an enlarged head 14 fitted lover the tubular projection 15 extending laterally from the duct 4 between the ends thereof. The head 14 and the tubular extension 15 present a cylindrical chamber and they clamp the marginal, iexible portion of the diaphragm member 16. To the central or body part the diaphragm member 16 has a bleed open- 19. Connected to the valve 5 is a spring '.20 which tends constantly to close said valve. Connected with the bard- 9 and extendi.g outward therefrom is the stopmember 21 projecting through the opening or port Sand the head 22of which engages the outside of the air-chest 2 when the port 9 is in normal position as shown in Fig. 2.
-In Fig. 2 the valve 5 is wide open and the bellows 6 in its expanded condition, where it is held by the spring 10, the valve 12 at this time uncovering the upper open end of the tube '13, The consequence is that said tube 13 will be in communication with. the
' atmosphere by way of the ports or openings 7 and The diaphragm-member, pouch or pneumatic 16 is s hown as being in the outer positlon where it is held by the pressure of air against the inner 'side there- 100 Patented ree. 2a, wie. i
`the bellows. The valve controls one end of of. The pump 3 is assumed to be in action and to be supplyingcompressed air to the chest 2 by way of the duct 4. One side of the diaphragm member 16 is presented to the atmosphere, the other side as noted being exposed to pressure by virtue of which the valve 5 Will be maintained in open p0- sition by the pressure. After a predetermined amount of air is in the chest 2, the part 9 of the bellows. 6 is moved to cause the valve 12 to close the adjacent end of the tube 13, thereby cutting off the diaphragm member 16 from the atmosphere. When this occurs compressed air passes into the tube 13 by way of the bleed opening 19 land when the pressure against opposite sides of the diaphragm 16 are balanced, the spring 20 becomes effective for instantly shutting the valve`5 and the valve will be maintained in shut relation as shown in Fig. 1 to cut ofi' communication between the pump 3 and the air chest 2 until the amount of air in the air-chest has been reduced sufficiently to permit the spring 10 to move the part 9 inward and cause the valve 12" to uncoverl the upper end of the tube 13. At this point the outer surface of the diaphragm member 16 'will be presented again to the atmosphere, so that the pressure in the duct 4 above the valve 5 can act against said diaphragm member 16 to move the same outward and thereby through the link 17 and crank arm 18 swing the valve 5 open.
What we claim is:
1. The combination of an air chest, a
pump for supplying air to the air chest, a
ldevice normally exposed to atmosphere onone side and exposed to pressure from the pump on the other side, a member operable by the pressure of the pump, means governed by said member, for cutting off communication -of said device with the atmosphere, and means controlled by said device when cutoff from the atmosphere for stopping the supply of compressed air to the air chest.
2. The combination of an air-chest, a pump -for supplying air to the air-chest, a device normally exposed to atmosphere on one side and exposed to pressure from the pump on the other side, a member in the air-chest operable by the pressure therein,
means governed by said member for cutting oif communication of said device with the atmosphere, and means controlled by said device when cut olf from the atmosphere forl stopping the supply of compressed air to the air-chest. l
3. The combination of an air-chest, a pump for supplying compressed air tothe air-chest, a device normally exposed to at-` mosphere on one side and exposed to pressure from the pumpon the other side, a member in the air-chest operable by the pressure therein, means governed by said member for cutting off communication of said device with the atmosphere, a valve, and means controlled by said device when the latter is cut off from the atmosphere for shutting the valve to thereby stop the supply `of air from the pump to the air chest.
4. The combination of an air-chest, a
pump for supplying air to the air chest, ay device exposed to atmosphere on one side.
and to pressure from the pump on the other side a member operable in one direction by the pressure of the pump, means for operating said member in opposition to the pressure of the pump, means governed by said member for cutting off communication of said device with the atmosphere when said member is operated by pressure,'and means controlled by said device when cut 0H from the atmosphere for stopping the supply of compressed air to the air chest. t
6. The combination of an air-chest, a pum'p for supplying air to the air-chest, a tube having an end opening to atmosphere, a device exposed 'to atmosphere .on one side, by way of said tube and to pressure from the pump on the other side, a member in the air-chest operable by the pressure therein, a valve connected with said member, for closing the atmosphere end of said tube through the action of said member at a predetermined point, a valve between the pump and the air-chest and operatively connected with saiddevice, and spring means for clos-` ing said second valve when said device is cut 0E from communication with the atmosphere.
7. The combination of an .air-chest, a pump for supplying air to the air-chest, a valve for controlling communication between the air-chest and the pump, spring means connected with the valve and tending ber, operatively connected with the valve, said diaphragm member having a bleed opening, a tube connecting the chamber with the atmosphere, a member in the air-chest, and a valve connected with said member, said member being operable to cause the valve to close said tube when a predeter- .mined amount of air is in the air-chest.
In testimony whereof we aix our signatures in presence of two witnesses.
