To all zit-may concern:

Kings and State of New York, have invented certain new and useful Improvements in Sihon-Closets, of which the following is a specication.

This invention has reference to siphon appagttus for water-closets and it is an objectt ereof to furnish a construction in which discharge outlet shall be of relatively large area throughout :its entire length,'so as to successfully pass obstructive materials of considerable mass, also to accomplish this result without the introduction of internal projections or providing the outlet with me-' cha'm'cal strictures or such other obstructive 'deyices'intrpducedin or extendin into the outlet of the discharge-pipe as wou d tend to clog the same and interfere with the movement-of the outgoing stream or catch up and stop any masses of material.

prior practices it has been common to reducethe outlet to form a choke, thereby 'to' more surely obtain thefwater-plug of sufii cient solidity to accomplish the siphoning action necessary to the proper operation 0 the closet. For accoml'ph'shng these objects the discharge-pipe of t e usual siphon form and arrangement is led out of the closet and then passes upward to .form the upper bend and then downwardand inwardly for the purpose more especially of bringing it to'a desirable position fortaking away the stream of the closet. With isset forth on the accompanying sheet of drawin s, whereon' j Q i ure 1 illustrates a sectional view of a bow with the improvement applied, and Fig. .2 isa' diagrammatic illustration of the action I of he stream in the outlet at the point of improvem'ent. p

I that the stream of water in coming down the portion 6 of the pipe 4 when it'reaches the point 7 naturally egins to spread, and itwill neissuedsuneiaisoe. Application for reissue filsii ll larch 30, 190.6 Serial No. 309,005,

then strike upon the abutment portion 8 of the enlargement or chamber 5. Thel wate'r striking upon said part 8 is naturally deflected and retarded in its movement, and the Water obstruction thus resulting to the oncom ing stream from the portion 6 tendsflal'l the more to fillthfe outward partof the chamber 5 with fluid, which in its turn tends further to obstruct the stream coming downthr ough the portion 6, and in connection withthis ac-v tion that portion 95 of the water directly dfi .fiected laterally toward the center of the pi'pefromth'e abutment-face 8 tends toform a fountain or water obstruction extending entirely across th'epipe and whichso'coacts with the incoming stream itself (obstructed and retarded, as ,already referredto) as to slow up the velocity of the water'immediately below in the portion 9 of the pipe, and thus form in that portionof the' pipe asolid stream."

notwithstanding. that the, said portion 9 of the outletipe may be as large, or nearly as large, as t 'This important result is also accomplished,

e upper portion 6. In this way any masses of material which will readily pass from the bowl throughthe outlet at 2 may be successfully passed through the entire length of the pipe, and so finallydisposed of without liability of the outlet-pipe becoming choked or blocked thereby at any portion in its length due to mechanical strictures in the outlet. In this way I form a water-plug in a ipe of relatively large size,.which plug will ro in a solid body through that portion 9 o the pipe 4, thus drawingdown the air as the plug preci itates and creates avacu um in 0 tion 6 o the said pipe 4. Thus an important feature accomplished in' thislipe fromthe improvement is that the outletomt Where it leaves the bow to, where it nall'y" enters the main pipe canbe of unrew I striated size throughout. v largement -of the outlet-pipe into ,a chamber would bring in the princl le in hydraulics (at least when the pipe is fiill offiuid) that the passageof a stream of a given velocity from a relatively small pipe into a largerpipe or chamber tends to re-forin the stream into one of'lar 'er diameter of lesser velocity and that this arger stream passing farther along The [sudden enthe conduit until it again enters the smaller j pipe at the point of such entrance again tends to re-form itself in a small stream whose velocity is equal to the reduction in the size of the stream.

The principle upon which my present improvement operates I a prehend is in sub stantial accordance wit the principle diagrammatically illustrated in Fig. 2. For instance, if'that portiontfi of pipe 4 be a pipe of, say, three-inch diameter and if the portion 6 be in line with and a continuation" of said portion 9, the two pipes being connectedby a large chamber, as 5, then water flow ng through the portion 6 at a' speed, for instance,

of ten feet in a given period will re-form on entering the chamber'5 into a stream of Cl1fiGI'-'-' ent size and-velocity. These speeds will of course be approximately roportionate, to the areas of the pipes, whic in the instance illustrated are about in the proportion of seven to nineteen, respectively-that is to say, the stream flowing through the portion 6 at a speed often feet per second :would normally re-form into a stream in the chamber 5 on the first discharge through the portion 6;

with a velocity of less than four feetzper second. In practice of course the stream does not instantaneously become a sohd stream but this com arison will serve to illustrate the principle l y which the water entering the pipe 9 from the larger portion 50f the conduit normally 0 erates to effect a fluid obstruction or c oke without the use of any reduction of the pi e and without the employment of any mechanical stricture or like device to interpose into the line of the pipe.

It will be noted that no mechanical ob struction is introduced within the conduit and no shoulder or device is made to project in any wise into the line of the outlet-pi e. The peculiar action of the apparatus y which the hydraulic choke is created is an action that is entirely different than would result from the introduction of any projection or abutment into the line of the conduit. It

will be observed that a very important'and' practical advantage of my resent improvement is that a complete sip onic action may be quickly and effectively produced in a vertical pipe without curves or bends an'd also freev of any mechanical choke orrestriction.

In Figs. 1 and 2 the dotted lines 19 20 indicate the pipe 4, continued from portion 6 to the portion 9 in line therewith. It may be here remarked that the first part of thestream of water coming down through the pipe (when the outlet-pipe'i's vertical, aspreerred in ractice) encounters'in the enlargement or c iamber a body of air normally stationary, and it is obvious the first effect of the descending water against such body of air will be to somewhat compress the air in the upper portion of said chamber, and thus tend to spread and divert the same, this action of the air being immediately opposed-by the relatively large surface at 2 1 There are thus set up within the chamber movements of air-currents somewhat com lex in character, but having as the result t ereof an impeding action on the incoming water. For illustration of one feature of this peculiar action of the inclosed airI have drawn the fine lines at. 22, indicating what I deem to be the probable lines' of resistance at the moment referred to within the mass of air in the air-- chamber, especially with regard to its tendency to flow out ofsaid chamber into the portion 9-, which lines, it will be noted, follow somewhat the arrangement of the, similar lines which are. understood-to beformedfin the case of sand flowingfout of'theordinary hour-glass.

By the term choke as used the claims I mean any kind of a choke which does not define itself with thewall' line of the outlet-pipe. i

A- feature ofmy improvement isth'at the discharge-conduitcomprises two. pi -sections of similar form and size, one lh cated above the other, but the two located al'mement, the interior- .of the conduit-sections communicating with an enlarged chamber combined with a laterally-disposed wall located outside of-th'e zone-of-the-conduit-opening or theinterior-wallof said conduit, and which-form's an a ron-orsplash-base for-deflecting the do owing stream into a plane transverse to the longitudinal axis ofthe-conduit, whereby this transverse flow creates a water-seat, upon which may pile other Waters emanating. from the inner-zones, so as to form a solidified water-plug, which .when' of'proper-weight so precipitates as to pro duce efiicient si honic action.

I'do not con e myself-to the precise construction and shape of'the outlet-as hereinshown and within the purview ofthis inventionmay resort to various modifications.
