Practice, moreover, has urher demonstrated that bv using rectangular fan casing-s, a greater area radiating surface is present in each' casing, Whieh condition serves to efectually dissipate objectionable or (iangerousrises in temperature Within the some. Obviously, any construction' tending ro decrease heat wihin ihe compressor is advantageous in he blowing-of organs.

Within each or theoasiiigs l, 2, and 3, and moimte for relation 'with the shaft 7, are fons 8, of any preferred type, Communica- ',tioh is established between the' nir inlet 95 ohmiiher 5, and the'ofssing l, by means o' an opening 9, see Fig. l2. Communication is esi'ahlished between heoasing Lend the first Connecting chamber 4, ,by virtue of' openings 10, see Fig. 3,` Communication is'- 103 established between the (za-sings 2, and 3,

Yihrough lie/second ohsmiloerl 4,*h-v similar tirely across and completely close the open-v ing G, in the bottom of the chamber 5. Felt is preferably employed, because of its excellent properties as a non-conductor of .found and because it is extremely porous. This, while eiectively serving to deaden noise generated within the com ressor, at the same' time permits of the 'ree passage of air through it. 0bvionsly, by making two ribbons of felt, corrugated, additional sound.- resisting area is provided. The end fan c asmg 3, is shown as having mounted upon its upper face an air outlet chamber 12, provided with an outlet port 13. Tle casing 3, is of a construction similar to the other casings with this exception that the outer tace lll, thereof is closed. in contra-distinction to being provided with outlets 10. Within the outlet chamber 12, are arranged superposed ribbons 15, of corrugated felt similar in all respects to the ribbons 11,`herein`betore described. By this arrangement and construction of parts, both the inlet and outlet ports of the air compressor are provided with nonconducting sound screens, which effectively serve to confine sounds within and preventthe escape thereof to the organ to which the compressor is attached.

it may be here remarked that one or more ot' the abovev casings may be used and in the case of using a single casing, the connecting chamber et, is dispensed with and the inlet and outlet chambers 5, and 153, are carried by a single casing.

'In operation, power from any suitable source is applied to the shatt 7, and the fan 8, in the casing 1, in revolving, draws air in through the screen 11, and the air being first compressed by the fan in the casing 1, is discharged through the openings 10, into the connecting chamber 4, thence, into the casing 2, and so on through a series of units, the number of which is determined by the requirements or' the organ until the air reaches the end casing, at which point it passes up through the screen 15, to the outlet port 13, from which point it is conveyed to an organ in the ordinary and well-understood manner.

.ln Figs. 5, and 6, a slightly modied form of screen for the inlet and outlet ports of the air compressor is disclosed. In lieu ot ribbons of corrugated felt hereinbeiore described, use is made of a layer of minerall slag wool. 16. As shown in said iigures, the sla g wool 1G, is confined by and between perforated metallic screens or wire gauze 17, "of coarse mesh.

That I claim is:

1. An air-compressor for blowing organs comprisin a series of spaced, separate rectangular an casings, adjacent casings havlng communication with one another, a connecting chamber of rectangular configuratien for establishing such communication, one end casing having an air inlet port therein, and the other end casing having an "air outlet port therein, a fan operative within each casing and a non-conducting sound screen of corrugated porous material operatively fitted across the respectlveports.

21h11 air compressor for blowing organs chamber, one end casing having a rectangular air inlet chamber and its complemental inlet port and the other end casing having an air outlet chamber and its complemental air outlet port, a fan operative within each casing and superposed ribbons of corrugated felt forming a non-conducting sound screen fitted within each of saidinlet and outlet chambers and across said inlet and outlet ports.

e. An aircompressor for blowing organs' v comprising a rectangular casing having air inlet and outlet ports, a fan operative therein and a non-conducting sound screen of c0rrugated porous material operatively fitted across the respective ports.

5. An air compressor for blowing organs comprising a rectangular casing having air inlet and outlet ports, a fan operative therein and a horizontally disposed non-conducting sound screen of corrugated-por0us material operatively. litted across the respec-I tive ports. v

In testimony whereof, I have herednto signed my name.
