Specification of Letters Patent.

Application filed May 29, 1916. fierial No. 100,582..

To all whom it may concern:

Be it known that I, BASIL G. AUSTIN, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Pneumatic Urgan-Actions, of which the following is a specification.

This invention relates to what I shall for.

convenience term pneumaticorgan action; The title adopted has been as noted, merely for convenience, although the mechanism is of particular advantage when incorporated in or forming part of a pipe organ; it is conceivable that {it can be used with equal utility in other connections. The action inis situated. v In the drawings accompanying and forming part of the present specification I have shown one convenient form of embodiment of the invention which I will set forth fully 'in the following description. I do not however, restrict myself to this disclosure; I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings:

Figure 1 is a transverse section of pneu-' matic organ action involving the invention.

Fig. 2 is an enlarged sectional view of the magnet-operated valve and its ad uncts.

Fig. 3 is an inside face view of the casing for the magnet operated valve, and,

Fig. 4 is anoutside face view of the cage for the pneumatically operated valve.

Like characters refer to like parts throughout the several views.

The relay mechanismcomprises a main support as 2 and an auxiliary support as 3. Both these may as usual be of wood. The main support 2 has certain windways,-here- 1 inafter described, while the auxiliary support 3 constitutes what is known as a relay bar. The two parts 2 and 3 are connected by parts as 1 having windways as 5; The

part 3 can be held to the part 2, and the connecting tubes 4 canbe maintained in assembled relation with said parts 2 and 3 in some permanent manner as by screws 6.

The sup ort. or bar 3 carries anumber of cases as generally made of'm'etal. Adetailed description of one case and its accesseries will, of course, apply to the other, and for this purpose reference may be had especially to Figs. 2 and 3. The case therein shown has on its inner side nearthe upper end thereof, the boss 8 adapted to snugly fit the passage 9, said case having near its lower end also on the irmer sidethe probar 3. The case 7 is,'therefore, removably mounted. It is held in position by a spring 12 connected with the relay bar 3 and'bearopen side of the case 7, fitting a rabbet therein, the packing 1'5 conveniently of paper, resting" on the bottom of the rabbet It.will be understood, that the thin packing 15 has between its ends a slot 15' in constant register with both the ports 18- and 19.

.jection 10 to fit the opening 11 inv the relay I ing against thev cap or cover member'13as will. hereinafter more particularly appear;

This cap or cover member 13 closes the outer 7 5 type, the poles of the. magnet being driven into holes inthe said part 13. The free end of the spring 12 to which I have already referred is fitted in an indentation 17 in the cover piece or supporting member 13. By

disengaging the spring 12 from said part 13; the latter can be dismounted as can also the? case 7. In the cover piece 13 are ports 18 and 19. In the case 7 is an approximately oval flange 20, the space in which constitutes a 'port in register with the port 21 of the relay bar 3, said port 21 being in commun1-.

similar soft nature. The parts 2 and 3 and their adjuncts hereinbefore described are generally inclosed in a pressure box 2, the result being that when the magnet 16 is deenergized, the pressure passing through the ports 18 and 19 closes the valve 22 against its seat as shown by full lines in Fig. 2.

The magnet 16 is normally denergized. I have shown as connected with the terminals of the magnet the wires 25 and 26 con-. stituting part of circuit connections which include a battery and a switch or other circuit-closing device. When the magnet .is

drawn bodily outwardly; so the valve is.

more efiiciently and easily opened.

On the support or relay bar 3 is mounted a pneumatic 27 in communication with the port; or passage 9 by way of the port 28. The movable member of the pneumatic is connected with the stem 29 of the valve 30 mounted in the cage 31. This cage consists of a sheet metal shell covering the port or windway 32 leading from a pneumatic (not shown). The valve 30 controls the port 33 which it is shown as closing inFig. 1. The cage or elongated shell 31 has in its outer side the, port 34 from which the annular flange 35 extends inward, the inner edge of said flange constituting a seat for the valve 30. The

' in communication with atmosphere as is the port 36 into which thepassage 5 hereinbefore described leads. The chamber 37 in the relay bar 3 with which the passage or windway 5 communicates is also as will be obvious, in communication with the "atmosphere. The shell 31 is merely fittedalong the edge of its open side against the support 2; initially it may be held in position by a small quantity of shellac placed along said edge, although this is not always nec essary, because it can be removably held in place merely by the use of the spring 38 (or equivalent means) of bowed form, one end of the spring being seated in the recess 39 in the upper edge of the relay bar 3, while the other end of the spring fits against the outer closed sideof said cage or oblong shell 31. For holding the cage or shell 31 in proper relation, the pins 40 may be provided, these ins extending somewhat freely through per orations in the outer closed side of the cage and being driven into the support or windway 33 is port or bar 2. The spring 38 has an eye at its inner end to fit over the upper of the two pins, by reason of which said upper pin aids in holding the spring in position. This provides an exceedlngly simple way of holding the cage 31 in place. The use of a valve as 30 and a valve as 22 and the hereinbefore described. adjuncts thereof is in no sense new, the only novelty being in the manner in which the cage 31 is mounted,

the Way the spring 38 is associated with said case, and the novel relation between the I valve22 and its operating'magnet 16 and certain. details as will be more particularly set forth in my claims.

.In Fig. 1 the parts are shown as occupying their normal positions, the valve 30 being closed against the inner end of the windway or port 33, while the valve 22 is closed against the port 20 as shown by full linesin Fig. 2. To obtain the pneumatic action as familiar in organs, the magnet 16 -will be energized to attract its armature '22 (constituting a valve) so as to cover the ports 18 'and 19 to pressure and put the pneumatic 27 into communication with the atmosphere. When this condition ensues, the pneumatic or bellows 27 will be collapsed so that the valve 30 will be drawn away from the port 33' and cover the port 34,

so that the windway 32 will be put into connection with the port 33 by way of the cage 31 to fi'ect the operation of the pneumatic or perform some equivalent act as quite common in or ans.

When t e magnet 16 is denergized the valve 22 is moved by the pressure in the pressure box against its seat on the flange 20 as shown by full lines in Fig. 2 thus that the packing 15 is free or loose, by-

reason of which it can be readily if desired.

What I claim is:

1. The combination of a support having a port and a windway, a cage inclosing the windway and having a port, a valve in the cage to alternately close said ports, and a spring acting against the cage to hold the replaced :same against said support.

2. The combination of a support having a port and a windway, a cage inclosing the windway and having 'a port, a valve in the cage to alternately close said ports, pins extending freely through the cage and driven into said support, and a bowed spring bearing against the cage to hold the same against said support, that part of the spring port; the pins and the cage acting jointly to which holds the cage in place, having an guide the valve.

eye to receive one of said pins. In testimony whereof I affix my signatu're 3. The combination of a support having in presence of two Witnesses.
