Valve for @Igan-Bellows, of which the following is a specification.
My invention relates primarily to air valves and has more especial reference to a type of air valve adapted for use in controlling the dow of fluid throu h air tubes used in connection with organ lowers.
The object of the invention is to produce an air valve which may be easily and readily applied to a fluid pipe and which may be operated easily and noiselessly.
A further object is to provide an air valve of this character which will be positive and effective in its closing movement.
With these objects in View the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claim, it bein understood that Various changes in the orm, proportions, size and minor details of construction may be made within the scope of the appended claim, without departing from the spirit or sacricing any of the advantages ofthe invention.
lln the accompanying drawings:
Figure l is a view of anorgan blower and bellows, showing my improved air valve applied thereto.
Fig. 2 is a longitudinal section through the valve.
Fig. 3 is a detached view ofthe same.
Fig. 4 is a section on line 4 4, Fig. 3.
Similar numerals of reference indicate corresponding parts throughout the several gures of the drawings.
The present invention is, while obviously applicable to many uses, primarily designed for use in connection with organ blowers and bellows, where large volumes of .air are forced through apipe, in the manner illustrated-in Fig. l. llt is necessary, in such a device, to provide means for automatically opening and closing the tube as the bellows is emptied and hlled with the air from the blower. llt is essential to also provide for edectively and positively closing the tube when the bellows islilled and at the Isame time to provide a device which will be noiseless in its operation in order not to interfere wlth the operation of the organ.
Referring more especially to the construction illustrated in the accompanying drawings, the numeral 1 indicates an organ blower of any usual and well known construction which is operated by means of the usual motor 2, an air tube 3, preferably of sheetv metal, connecting the blower with the ordinary organ bellows d, which may be of any usual and well known construction'. My improved air valve is located in this air tube 1ntermediate the blower and the bellows and comprises the cylinder 5, within which the movable vane is pivoted, said cylinder being preferably provided with the reduced ends 6 arranged to receive the extremities of the tube 3.
-Journaled transversely through the center ofthe cylinder 5 is a. shaft 7 upon which shaft is ixedly mounted the movable vane, which will be hereinafter described. 'llo the outer extremity of the shaft 7 is lixedly attached a lever 8 having a small weight 9 located near its free extremity. A suitable cord or other flexible member l0 is connected to the member 8 and passes up over the pulleys 11 and downwardly where it is connected to the top of the bellows Ll.
rlhe movable vane comprises the elliptical plate 12 and the elliptical frame member 13, which is secured to said plate by means of a plurality of bolts la or their equivalents,
a strip of felt or other suitable insulating materlal i6 being clamped between said plate and frame member. A semi-cylindrical indented portion i7 is provided transversely,
across the elliptical plate l2 and similar indented portions 18 are provided in the frame i3, these being for the purpose of receiving 'the shaft 7 to which the vane is liXedly connected by clamping the elliptical plate and frame member together upon said vane. The felt strip 16 extends beyond the periphery of the plate l2 and frame 13 and is arranged to contact with the interior of the cylinder 5when the valve is in the closed position.
When the blower is operated the bellows is indated to its highest point when the weight 9 upon thev arm 8 will roch the shaft 7 into a position to close the air valve, the vane being moved into the position best illustrated in Fig. 2 of the drawingathe felt strip lt contacting with the interior ot the cylinttl 'lll
llltl der 5, thus shutting' of all airfrom the blowei` tothe bellows. After the keys and stops of thearm 8- and open the valve enough to supplythe bellows with suicient air and as more stops are operated upon the organ the valve will be accordingly opened as the demand requires, the valve being again closed when the stops are pushed back, thus properly regulating the wind pressure of the organ under all conditions of playing. The movement of the valve will be noiseless as the felt strip is the only portion of the vane which comes into contact with the interior ci the cylinder 5 thus the operation of the organ isynot interrupted or interfered with.
ll claim ln a device of the character described, the
Leashes Ithereof, a flexible member adapted to pass over a series of suitably arranged pulleys and means for operatively connecting the said flexible member to the saidvane and the said bellows to close the said vane when the bellows is filled and open said vane as the bellows empties. v
In testimony that I claim the above, I havehereunto subscribed my name.
