To all whom it may concern: l

Be it known that I, WILLIAM E; HASKELL,

a citizen of the United States, residing at Brattleboro, in the county of Windham and trolling the same is called the Oboe stop;

and the object of the present improvement is to secure this characteristic and peculiar tone by the construction andvoicing of the pipe without the employment of any vibratr mg reed or other moving part.

The improvements are illustrated in the accon; inying drawings in whicha a Figure 1, is a front view of a metallic organ pipe embodying the improvements.

Fig .4, isa cross-section'in the plane indicated by the line 4: 4 in Fig.3. Fig. 5, is a horizontal section in the lane indicated by the line 5-5 in Fig. 3. ig. 6, is a detail view of the lower lip and. the languid. p

A,'is the body of the ipe; B, is its foot, having toe a, with port, C, is the mouth, having upper lip'c, and lower lip 02; D, is the languid,

the windway e; E, is a cup below the mouth,

i I and between the front of which and the front- ,of the foot is a throat f; F, is a roller or draft bridge, infront of the lower portion of the mouth and mounted in vertically extending ears 9, on o osite sides of the mouth; G, is the tuning slit, and. H, is the tuner.

All of: the pipes are made of the usual metal employed in the manufacture of me tallio organ pipes. The smaller pipes of thesto 'are'made of'a composition of tin and lea 'and the larger pi es are made of zinc.

The pipes are. open at t eir to s.

In order that the characteristics of the im proved set of pipes may be fully understood, a s ecification will be given of the exactdetai s which have been followed in the COLIl-r mercial manufacture of the pi es,

The front of the pipe is attened at the mouth so that the mouth entends in a plane fipeci hc aticn of Letters Patent. 'hpplicatioafiloli June 24:. 1905- Beriel No. 266.838-

fifths the diameter of the mouth, and the between the two ears 9, g. The width of the maximum diameter of the body of the pipe is six-fifths the diameter at the mouth. The maximum diameter of the body of the pipe is substantially half way between the mouth and the top of the p1pe. The, body of the pipe gradually diverges from the mouth to the middle, and then gradually converges from the middle to the top. The cup E, isan im ortantfeature of the pipe, and its depth helowthe level of the lower lip is equal to the diameter ofthe body of the pipe at its tops The voicing of the pipe is likewise important.

The up or and lower lips should be bev- I eled as s own to have sharp edges. The roller or draft bridge F, is of wood, and is stationary between the ears, being fixed thereto by a pin h. The bridge is circular in crosssection, and its diameter is four-fifths the height of the mouth. It is so placed that its center is substantially on a level with the top of the lower lip, and the distance between it and the upper edge of the lower lip (at their points of nearest approach) should be aprogrimately one-fifth the diameter of the rx go. I

The bottom of the languidD, is at the same level as the top of the lower lip. The

front face of the languid is beveled to a sharp edge. The width of the windway a, between the languid and the lower lip may be varied to a considerable extent, do ending u on the volume of tone required an the dept of the nicking on the languid. As a proper average roportion, it .may be stated that the win Way may be about one fortieth as wide as the mouth is wide. I

The proportions of the foot B, with its inlet I), may follow ordinary organ practice in the construction of metal pipes, having no peculiarity in the present improved stop.

. The lengths of the different pipes in the stop are,' of course, determined by their pitch In the stop which has been commer. cially adopted, the CC is the lowest note of an 8 foot register. The heightof this pipe.

from the level of the lower lip to the extreme top of the pipe is 94.25 inches. The diameter at the mouth forthis'pipe is 3.25 inches, that is to say, the length.- of the pipe is I twentyqiine times its diameter at the stop follow the usual rule governing the pitch of the pipes, that is to say, each pipe is on'e-halfthe heightoi the octave belowpipe, and it entirely open,

The diameters of the pipes do not vary inthe same proportion as do their heights.

' Taking any given pipe as unity the nine teenth pi e'counting from it has half itsv diameter, 1 at is to say, if CC is 3.25 inches n diameter, then the nineteenth pipe counting froniit, namely, Fsharp, is 1.625 inches in diameter. In this count it is to be noted that both the first and last pipes are to be recognized. The intermediate pipes vary in diameter in regular geometric progression.

"l. he proportions of each pipe, as based u on the diameter of its mouth as heretofore given, should be'followedinv all pipes of, the sto The pro ortions which have been given, if exactly to lowed, will reduce a set .of pipes giving the desired qua lty of tone. It is not, however, to be inferred that there can be no departure whatever from these proportions, since they may be varied within limitswithout destroying the tone quality.

The mechanical'construci'ion of they cup E, possesses mechanical novelty and advanta e. he cup is made of the same metal as t 1e has a closed bottom and eripheral walls all in one piece of metal. T e bot-- tom is fiat,-as is likewise theifront i. The cylindrical portion m, of the cupfits snugly Within the pi e and is conveniently secured in place by so dering. The top of the cup is and the languid D, is conveniently secured in place by solderin lg to the top of the front wall 'i, of the cup. he cup fits snugly within the pi e so that wind can only pass through the t roat f, betweemits front Wall and the external body of the. pipe at the front.

The cup constitutes the 'bottom' of the pipe-and is below the mouth with its-u per open end at the level-of the bottom 0 the mouth and with its bottom a distance below the mouth substantially equal to the diameter of the top of the pipe. I

I claim as my invention:

1. A metallic organ pi e open atits top and having'a' mouth an having a body the diameter of which at the top is smaller thantlie major diameter in the planeof the mouth, and the diameter of which at the middle is larger than said major diameter at itsmouth.

2. A metallic organ pipe having amouth verges gradually characterized by and charabterized byhaving its top ap roxiinately one-fifth smaller in diameter t anit' is at the major diameter in the plane of the mouth, by .one-fifth arger in diameter than it is at said major diameter at its mouth, and by diver ing gradually from the mouth to the middland by converging dletotheto. J3. Ame-ta lic organ ipe characterized by having its upper and ower -li s beveled at having its middle approximately gradually from the midtheir outer-faces to a sharp e ge, having a languid-beveled atits front to a sharp edge,

the-bottom of said languid beingat substari- 1 tially the level of'the top of the lower lip, and

lower portion of the mouth.'

4. A metallic or an pi' e characterizedby. having a month t e wi th of which is approximately onefifth the" circumference of the pipeat the mouth, and the height. of

which. is approximately two-sevenths of its Width, and a draft bridge in front of the lower portion ofthe mouth Whose diameter is sublptantially four-fifths the height of the mout 5. A metallic organ pipe having a windway, a mouth, and a metallic oi 1p open at its top, closed at its. bottom, and fitting closely within the pipe, said cup constituting-the bottom of the pipe and having its open top at said mouth, a throat being left between the front of the cup and the front of the pipe for the passage of wind to the windway.

6. An open top metallic organ pipe having a mouth, a windway, a languid, and admit bridge, and characterized by the following features, namely, (a) its top is ap roxi- 'mately one-fifth smaller in diameter t an it is at its major diameter in the plane of the mouth, its middle is approximately. one-fifth larger in diameter than it is at said major diameter at its mouth, it diverges gradually from the mouth to the middle, and it confrom its middle to it's top;

(b) it hasa cup with itsbottom below the mouth a distance substantiallysquat-toithe diameter of its top; (0) the up er and lower.

li s at its mouth are each have ed toe sharp a or go, ari'dits languid is beveled to-a sharp edge; (dithe width of its mouth is approxi mately one-fifth the circumference of the pipe at the mouth, and the height of the mouthis approximately-two-sevenths of its width, i

and (e) its drafti bridge is in front of the:

j lower portion of the mouth and has a diame' tersubstanti'ally four-fifths the height of the mouth.

In witness whereof, I have hereunto si ned my name in the presence oftwo subsori "pg witnesses.
