ORGAN-PIPE.

Specication of Letters Patent.

Patented May 19, 1914.

- Application led September 25, 1913. Serial No. 791,769.

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 Organ- Pipes, of which the following is a specification.

This invention relates to organ pipes, among the objects 0f the invention being the provision of simple and effective means by which the formation of eddy currents therein is avoided to thus prevent windiness7 as it is known and also by which the amount of air to be supplied can be accurately and precisely regulated by virtue of which latter point 'the volume of sound can be governed or adjusted.

In the drawings accompanying and forming part of the present specification I have shown in detail two of the many forms of embodiment of the invention which to enable those skilled in the art to practise the same will be set forth fully in the following description. I may depart in several respects from the disclosure thus made within the scope ofthe invention defined by the claims following said description.

Referring to said drawings: Figure l is a sectional side elevation 'of a metal pipe embodying my invention. Fig. 2'is a simi-A lar View of a wooden pipe equipped with the invention in a slightly different form.

Like characters refer to like parts in both figures.

As will be inferred from what has already been stated the invention comprises two features, one by which the formation of eddy currents in an organ pipe is preventedsand the other by which the intensity of sound can be varied, and these can be employed separately, although in both forms of the device, one means secures both results.

In Fig.` l the numeral 2 denotes the lower portion of a metal organ pipe, the footl 3 of which is downwardly taperedafter the usual fashion, said pipe haviig in the lower part of its foot the air inlet port 4 and having in its body the mouth 5 below which is disposed the customary languid 6. I provide means for dividing the air which enters the pipe by way of said inlet port 4 or otherwise, into a multiplicity of streams or jets, by reason of which eddying of the air within the foot of the pipe or below the languid 6 is not possible, and the vmeans by which this result can be obtained may vary as to character, two different 4forms being shown herein, one especially welly adapted to the meta-l pipe shown in F ig. l, andthe other to the wooden pipe illustrated in F 2. Re-

ferring again to Fig. 1 the numeral 7 designates a cylinder which as shown is integral with the foot '3, and which rises from the port 4. This cylinder hasin it a large number of perforations or holes 8. It, therefore, follows that thev air by which the pipe 2 is made to speak, must pass through some or practically all these openings, the result being that the air is delivered as already intimated, into the pipe in a large number of jets orl streams. In like fashion various means'may be provided for regulating the amount of air. As shownthe cylinder 7 contains an adjustable cylindrical plug 9 'which can be made of wood or other suitable material and which comparatively closely fits the interior of said cylinder but which is capable of relative free movement up and down therein and by which certain of.y the perforations of the cylinder 7 can be thrdwn into and out of use.

In Fig. l the plug 9 constituting a' suitable valve is shown asbeing substantially midway of the height of the cylinder or tube 7, the consequence being that the air which enters the port 4 cannot pass through the perforations 8 covered by the plug 9 or Athrough those above said plug but can only go through the perforations below the plug. By moving the plug up or down the number of perforations which are to be used can be increased or decreased to correspondingly vary the amount ofvolume of sound of the pipe. If the amount of air entering the pipe be considerable the tone' will be heavy, while if the plug be lowered the tone will be lighter. Fastened to the plug 9 and rising therefrom -is the elongated stem 10 which extends through a guide hole or openingin the-languid' 6 and which at its upper end is equipped with .a button or like operatingl part which can be grasped to move the stem l0` longitudinally and thereby effect the elevation or lowering of the plug 9. It will be seen that the button or equivalent portion 11 of the stem is readily accessible, owing to the fact that it is opposite the mouth 5 and it ean be reached l bythe hand or a suitable tool to adjust thi` l plug t), which is a feature of advantage. l llie stein ean be eontinued below the plug l J foiijngiediaito a hook 10 .so that the plug eari""lo be shittedpfroin liielow the pipe Iirlfig. i), the organ pipe lf2 is et' wood, and its foot constituting a suitable valve as will hereinafter appear is denoted by 13, the open lower end et said foot presenting a port Jtor the. entrance of air into said pipe, the languid of which is designated by 14C and the mouth by 15. In the upper portion of the toot 'l-3 is a perforated metallic cylinder le closed at its upper end. To said elofred upper end is Connected the shank or red 1T projerting through a guide hole in the languid 1-1 and having a button 1S which can be re: ehed by the hand or a suitable iinplenient passed through the mouth 15 to eiiieet raising or lowering of the perforated cylinder 16. By raising or lowering said cylinder 16, the pei't'orations therein can be more or leas covered by the floot 13 to vary the anionnt of air passing into the pipe 12. In similar fashion thin cylinder 1G divides the air into a large nuinber of jets. The Stein 1T can also be extended downward as at 1? to provide tor the adjutinent of the cylinder 1G below the pipe 1Q, the lower end of the extension 17 terminating in a hook to 'laeilitate changing the position oit said cylinder.

that I elaii'n iS: 1. An organ pipe having a languid, an air inlet,- port, and means between the port and said languid, for directingT air into said pipe l in a multiplicity or jeta, said means being spared l'roin Asaid languid.

i. fin organ pipe eoinbined with means eoiiipi'i: ii'ig a perforated cylinder for directing the air in jet:4 into the pipe, and means whereby the amount of air thus delivered can be varied.

3. An organ pipe having an air inlet port. a perforated cylinder eonneeted with Said port through the perforations ot which air p-.iesea into the pipe, and a plug adjustable in the cylinder and movable to regulate the amount of air entering the pipe.

l. Ain organ pipe having a languid and an air inlet port, a perforated cylinder eonneeled with said port and which the air is divided into jetsi for Supply to the pipe in such condition, a plug in said Cylinder adjustable to regulate the amount of air entering the pipe, and an operating rod connected to said plug and extending mouth opposite the upper portion of said rod.

5. An organ pipe having a perforated cylinder tor directing air in jets thereinto7 and a 'valve for Said perforated Cylinder, the perforated eylinder and valve being relatively movable to Yary the amountot air to be deliveredA into said pipe.

in testimony whereof l athx my Signature in presence of two witnesses. f
